> - Issue #6043 `Min` is always `0` in `Summary Report` (fixed in 5.6.3) The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The numbers that appear to the left of the green box are the number of active threads / total number of threads, the total number of threads only applies to a locally run test, otherwise it will show `0` (see Bug 55510 ).

> ### HTTP Samplers and Test Script Recorder Pull request #6010 - Use UTF-8 as a default encoding in HTTP sampler. It enables sending parameter names, and filenames with unicode characters Pull request #6010 - Test Recorder will use UTF-8 encoding by default, so it will infer human-readable arguments rather than percent-encoded ones
> Non-functional changes
> Pull request #6000 - Add release-drafter for populating GitHub releases info based on the merged PRs Pull request #5989 - Use Gradle toolchains for JDK provisioning, enable building and testing with different JDKs, start testing with Java 21 Pull request #5991 - Update jackson-core, jackson-databind, jackson-annotations to 2.15.2 (from 2.15.1) Pull request #5993 - Update ph-commons to 10.2.5 (from 10.2.4) Pull request #6017 - Update kotlin-stdlib to 1.8.22 (from 1.8.21) Pull request #6020 - Update error_prone_annotations to 2.20.0 (from 2.19.1) Pull request #6023 - Update checker-qual to 3.35.0 (from 3.34.0) ### Other Samplers Pull request #6028 - Change default value for `sampleresult.default.encoding` to UTF-8 (it inherits default HTTP encoding which was modified in Pull request #6010 - )
> Bug fixes
> ### Thread Groups Pull request #6011 - Regression since 5.6: ThreadGroups are running endlessly in non-gui mode: use default value for LoopController.continue_forever rather than initializing it in the constructor ### Other Samplers Pull request #6012 - Java Request sampler cannot be enabled again after disabling in UI (regression since 5.6)

> ### Thread Groups Issue #5682 Pull request #717 - Open Model Thread Group: avoid skipping rows from CSV Data Set Config Support custom thread group implementations in "Add think time" and "Save as test fragment" actions Open Model Thread Group: interrupt pending HTTP requests and other `Interruptible` test elements on test stop ### HTTP Samplers and Test Script Recorder Pull request #5911 - Use Caffeine for caching HTTP headers instead of commons-collections4 LRUMap Pull request #5947 - Fetch resources referenced in `<link "rel"="preload"...>` elements Pull request #5869 - Allow more templates to format sampler names in the recorder: `#{url}`, `#{method}`, `#{scheme}`, `#{host}`, `#{port}` ### Other samplers Pull request #5909 - Use Caffeine for caching compiled scripts in JSR223 samplers instead of commons-collections4 LRUMap ### General Pull request #5792 - Add KeyStroke for start_no_timers (Start no pauses: CRTL+SHIFT+n) Pull request #5899 - Speed up CPU-bound tests by skipping `recoverRunningVersion` for elements that are shared between threads (the ones that implement `NoThreadClone`) Pull request #5914 - Use `Locale.ROOT` instead of default locale for `toUpperCase`, and `toLowerCase` to avoid surprises with dotless I in `tr_TR` locale Pull request #5885 - Use Java's `ServiceLoader` for loading plugins instead of classpath scanning. It enables faster startup Pull request #5788 - `FunctionProperty` no longer caches the value. Previously it cached the values based on iteration number only which triggered wrong results on concurrent executions. The previous behavior can be temporary restored with `function.cache.per.iteration` property. Pull request #5920 - Improve HTTP HeaderManager performance when it contains many headers: skip reinitialization on each iteration Pull request #5920 - Use AtomicInteger and AtomicLong instead of synchronized primitives for JMeterContextService#numberOfThreads Pull request #5920 - Cache bean properties in `TestBeanHelper` and avoid synchronization, so test plans with `TestBean`-based elements is faster Pull request #5920 - Improve computation when many threads actively produce samplers by using `LongAdder` and similar concurrency classes to avoid synchronization in `Calculator` Pull request #5920 - Reduce synchronization contention on `AbstractTestElement` that are shared between threads (the ones that implement `NoThreadClone`) Pull request #5934 - Added caching for date formatters for `__time` function Pull request #710 - Issue #5666Added Shortcut key event for Reset search: `ctrl + alt + F`, `cmd + alt + F` Pull request #5959 - `TestElement` has been migrated to Kotlin, so nullable types are annotated better Pull request #5944 - Add PI for declaring `TestElement` schemas so element properties are easier to access in code (see `TestElementSchema`, `TestElement#getSchema()`, `TestElement#getProps()`) Pull request #5944 - Enable usage of `${...}` expressions for checkbox controls (see context menus for checkboxes, however, the individual components should be adapted individually) Pull request #678 - Experimental Kotlin and Java DSL for programmatic test plan generation (see Creating a plan with Kotlin DSL)

> New and Noteworthy
> JMeter now supports Java 17 JMeter 5.5 ships with log4j2 2.17.2
> Open Model Thread Group
> New component: `Open Model Thread Group` allows creating load profiles with variable load. For example, if you need to gradually increase load from `0/sec` to `10/sec` during `minute` you could previously use `Thread Group + Timer` combinations. However, then you need to compute the expected number of threads, ensure they are created only when needed, and so on. With `Open Model Thread Group` you can configure the same load profile as `rate(0/sec) random_arrivals(1 minute) rate(10/sec)`. The thread group would spawn threads as needed to drive the configured load. The load profile can use properties, so you can launch the same script with slightly different load levels, however, the profile can't be updated while the test is running. The new thread group is experimental in JMeter 5.5, so please feel free to submit your feedback.
> Open Model Thread Group sample
> Preparing the deprecation of Oro Regex usage
> Another experimental feature in JMeter 5.5 is the ability to replace the Oro based Regex implementation by the built-in Java based one. To choose the Java based one, set the JMeter property `jmeter.regex.engine` to the value `java`.
> Core improvements
> Kotlin language is now used in some core classes and tests (e.g. Open Model Thread Group). JMeter is compiled with `apiTarget=1.5`, and it ships with `kotlin-stdlib` 1.6. lets-plot-kotlin charting library is added, so it will be easier to refine and create new charts in UI in the future.

To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing the Java `jdk.certpath.disabledAlgorithms` property. Remove the MD2 value or the constraint on size, depending on your case. This property is in this file:

Since Java 11 the JavaScript implementation Nashorn has been deprecated. Java will emit the following deprecation warnings, if you are using JavaScript based on Nashorn.
>       Warning: Nashorn engine is planned to be removed from a future JDK release
>   To silence these warnings, add `-Dnashorn.args=--no-deprecation-warning` to your Java arguments. That can be achieved by setting the enviroment variable `JVM_ARGS`

> -   With Java 15 the JavaScript implementation Nashorn has been removed. To add back a JSR-223 compatible JavaScript engine you have two options: Use Mozilla Rhino Copy rhino-engine-1.7.13.jar into `$JMETER_HOME/lib/ext`. Use OpenJDK Nashorn The OpenJDK Nashorn implementation comes as a module. To use it, you will have to download it and add it to the module path. A hacky way to download the version 15.0 and its dependencies and set the module path is outlined below:

> Bug 62179 - Bug 64658 - The splash screen is now application-modal rather than system-modal, so it does not block other applications when JMeter is starting up.
> Incompatible changes
> Remove LogKit logger functionality from some classes. This was intended to completely remove `LoggingManager` class (it has been deprecated since JMeter 3.2), but as jmeter-plugins depended on it, `LoggingManager` and our `LogKit`-adapter will remain for this version (but is still deprecated).

> New and Noteworthy
> UX improvements
> Darklaf Tree indentation level is easier to follow:
> JMeter tree with Darklaf Darcula theme
> JMeter tree with Darklaf IntelliJ theme
> New look and feel themes. Light: IntellJ, Solarized Light, HighContrast Light. Dark: OneDark, Solarized Dark, HighContrast Dark. When an element in tree is disabled, all its descendants are shown in gray. For instance, `While Contoller` is disabled in the following tree, so its children are gray. It is purely a UI change, and the behavior is not altered.
> While controller is disabled, so its children are gray
> Tree context menu is shown even in case the node selection is changed. Previously the popup did disappear and it was required to select a node first and only then launch popup. Look and feel can now be updated without a restart Use CTRL + ALT + wheel for zooming fonts. Previous shortcut was CTRL + SHIFT + wheel, however, it conflicted with horizontal scrolling. In-app zoom is more consistent (e.g. sometimes not all the labels or even panels were scaled). For instance: log viewer, JSR223 code editor were not previously scaled with zoom-in/out feature Tree context menu is shown for the full row, not for the label only Undo and redo support for editable fields. Keystrokes are CTRL + Z / CTRL + SHIFT + Z, or CMD + Z/ CMD + SHIFT + Z depending on the operating system. Undo is implemented on a field level basis (each fields has its own history), and the history is invalidated when tree selection changes. Mark the currently selected language in the options menu. Mark the currently selected log level in the options menu. Rework of many Test Element UI (JUnit Request, ForEach Controller, If Controller, Throughput Controller, WhileController, Counter Config, XPath2 Extractor, Function Helper Dialog, Search popup, JMS Elements)

> New and Noteworthy
> Core improvements
> JDBC testing has been improved with ability to set init SQL statements and add compatibility with JDBC drivers that do not support QueryTimeout
> Various bug fixes have been implemented, like gathering the correct headers when recording requests through the HTTP(S) Test Script Recorder using HTTPS In version 5.0, JMeter was changed to rename Sub results using a custom Naming Policy (Bug 62550 ). This change could be annoying for Functional Testing, a new property `subresults.disable_renaming=true` has been introduced to revert if needed to previous behaviour. An alternative is to check `Functional Test Mode` in Test Plan, see Bug 63055
> UX improvements
> Templates can provide parameters that are filled in on test plan generation, `Recording` template uses this feature
> A new `Tools` menu has been introduced to collect those entries, that are used for general usage around JMeter, like: `Function Helper Dialog` `Export transactions for report` `Generate Schematic View` which provides an overview as HTML of the Test plan `Import from cURL` which allows you to create or update your test plan by importing a cURL command `Compile JSR223 Test Elements` `Create a heap dump` `Create a thread dump`
> Test Plan
> Ability to create a Test plan from a cURL command.
> Scripting / Debugging enhancements
> A menu item to compile all JSR223 Elements is now available in `Tools` menu
> Live Reporting and Web Report
> A JSON file containing summary of a load test statistics is now generated when using `-e` or `-g` options. Percentiles computing graphed over time algorithm has been modified to restart for each time slot More user-friendly behaviour when reporting folder does not exist or is not empty through `-f` command line option
> Incompatible changes
> In `Response Time Percentiles Over Time (successful responses)` graph of the HTML report, before this version, percentile computation of each time slot used the percentile data of previous time slot as a base. Starting with this version, each time slot is independant. See Bug 62883 `ClientJMeterEngine#rsetProperties` signature has been changed to use `HashMap<String,String>` instead of Properties, see Bug 63034 A new Menu item `Tools` has been introduced, some menu items that were in `Help` menu are now under this new menu item. See Bug 63094 `slf4j-ext` has been removed from libraries (lib folder) and JMeter pom. It was not used by default and due to CVE-2018-8088 and unavailability of a stable version containing a fix to this issue, we decided to remove it. If you still needed, you can add it in lib folder.

> Known problems and workarounds
> - The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The numbers that appear to the left of the green box are the number of active threads / total number of threads, the total number of threads only applies to a locally run test, otherwise it will show `0` (see Bug 55510 ). Note that under some windows systems you may have this WARNING:
>       java.util.prefs.WindowsPreferences
>       WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
>       x80000002. Windows RegCreateKeyEx(…) returned error code 5.
> - The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore. You may encounter the following error:
>       java.security.cert.CertificateException: Certificates does not conform to algorithm constraints
>   if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature algorithm using MD2 (like `md2WithRSAEncryption`) or with a SSL certificate with a size lower than 1024 bits. This error is related to increased security in Java 8+. To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing the Java `jdk.certpath.disabledAlgorithms` property. Remove the MD2 value or the constraint on size, depending on your case. This property is in this file:
>       JAVA_HOME/jre/lib/security/java.security
> See Bug 56357 for details. Under Mac OSX Aggregate Graph will show wrong values due to mirroring effect on numbers. This is due to a known Java bug, see Bug JDK-8065373 The fix is to use JDK8_u45 or later. View Results Tree may fail to display some HTML code under HTML renderer, see Bug 54586 . This is due to a known Java bug which fails to parse "`px`" units in row/col attributes. See Bug JDK-8031109 The fix is to use JDK9 b65 or later. JTable selection with keyboard (SHIFT + up/down) is totally unusable with Java 7 on Mac OSX. This is due to a known Java bug JDK-8025126 The fix is to use JDK 8 b132 or later. # Version 5.0 Summary New and Noteworthy Incompatible changes Bug fixes Improvements Non-functional changes Known problems and workarounds Thanks
> New and Noteworthy
> Core improvements
> Rest support has been improved in many fields Multipart/form-data requests now work for `PUT`, `DELETE` … It is now also possible to send a JSON Body with attached file Parameters entered in Parameters Tab are now used in body instead of being ignored
> In distributed testing, JMeter now automatically prefixes thread names with engine host and port, this makes the counting of threads correct in the HTML report without any other configuration as it was required before
> XPath 2.0 is supported in a new element called `XPath2 extractor` providing easier XML namespaces handling, up to date XPath syntax and better performances
> Upgrade to HTTP Components 4.6 last APIs has been completed and JMeter does not rely anymore on deprecated APIs of this library It is now possible to control in an easier way Loop breaking and Loop switching to next iteration. This is available in `Flow Control Action` and `Result Status Action Handler` elements
> While Controller now exports a variable containing its current index named `__jm__<Name of your element>__idx`. So for example, if your While Controller is named WC, then you can access the looping index through `${__jm__WC__idx}`
> Scripting / Debugging enhancements
> Search feature has been improved to allow you to iterate in the tree over search results and do necessary replacements through `Next`/`Previous`/`Replace`/`Replace/Find` buttons
> In View Results Tree, the request and response headers/body are clearly separated to allow you to better inspect requests and responses. You can also search in all those tabs for a particular value
> Recording feature has been improved to provide a popup that is always on top when you navigate in browser allowing you to name transactions while you navigate in your application.
> You can now restart JMeter from menu File → Restart
> Live Reporting and Web Report
> A new Graph Total Transactions per second has been added to the HTML Web Report
> It is now possible to graph over time custom metrics available as JMeter Variables through `sample_variables`. Those custom metrics graphs will be available in the HTML Report in `Custom Graphs section`
> Hits per second graph now takes into account the embedded resources
> In Live reporting, the sent and received bytes are now sent to Backends (InfluxDB or Graphite)
> Functions
> A New function `__threadGroupName` has been introduced to obtain ThreadGroup name.
> Incompatible changes
> Since JMeter 5.0, when using default HC4 Implementation, JMeter will reset HTTP state (SSL State + Connections) on each thread group iteration. If you don't want this behaviour, set `httpclient.reset_state_on_thread_group_iteration=false` Since JMeter 5.0, in relation to above remark, `https.use.cached.ssl.context` is deprecated and not used anymore. Since JMeter 5.0, when using CSV output, sub results will now be also output to CSV file. To revert to previous behaviour set `jmeter.save.saveservice.subresults=false`, see Bug 62470 , Bug 60917 , Bug 62550 . Since JMeter 5.0, `CSS/JQuery Extractor` has been renamed to `CSS Selector Extractor` Since JMeter 5.0, `Test Action` has been renamed to `Flow Control Action` Since JMeter 5.0, JMeter renames subResults to `parentName-N` where N is a number to ensure that Hits Per Second graph includes resources downloads, see Bug 62550 , Bug 62470 and Bug 60917

> Known problems and workarounds
> - View Results Tree may freeze rendering large response particularly if this response has no spaces, see Bug 60816 . This is due to an identified Java Bug UI stuck when calling `JEditorPane.setText()` or `JTextArea.setText()` with long text without space. The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The numbers that appear to the left of the green box are the number of active threads / total number of threads, the total number of threads only applies to a locally run test, otherwise it will show `0` (see Bug 55510 ). Note that under some windows systems you may have this WARNING:
>       java.util.prefs.WindowsPreferences
>       WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
>       x80000002. Windows RegCreateKeyEx(…) returned error code 5.
> - The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore. You may encounter the following error:
>       java.security.cert.CertificateException: Certificates does not conform to algorithm constraints
>   if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature algorithm using MD2 (like `md2WithRSAEncryption`) or with a SSL certificate with a size lower than 1024 bits. This error is related to increased security in Java 8+. To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing the Java `jdk.certpath.disabledAlgorithms` property. Remove the MD2 value or the constraint on size, depending on your case. This property is in this file:
>       JAVA_HOME/jre/lib/security/java.security
> See Bug 56357 for details. Under Mac OSX Aggregate Graph will show wrong values due to mirroring effect on numbers. This is due to a known Java bug, see Bug JDK-8065373 The fix is to use JDK8_u45 or later. View Results Tree may fail to display some HTML code under HTML renderer, see Bug 54586 . This is due to a known Java bug which fails to parse "`px`" units in row/col attributes. See Bug JDK-8031109 The fix is to use JDK9 b65 or later. JTable selection with keyboard (SHIFT + up/down) is totally unusable with Java 7 on Mac OSX. This is due to a known Java bug JDK-8025126 The fix is to use JDK 8 b132 or later. # Version 4.0 Summary New and Noteworthy Incompatible changes Bug fixes Improvements Non-functional changes Known problems and workarounds Thanks
> New and Noteworthy
> Core improvements
> JMeter now supports JAVA 9. New `Boundary Extractor` element available which provides easy extraction with better performances
> New `JSON Assertion` element available to assert on JSON responses.
> New `Precise Throughput Timer` element available which produces Poisson arrivals with given constant throughput.
> JMS Point-to-Point sampler has been enhanced with `read`, `browse`, `clear` options.
> - Best property values are now selected on many Test Elements to ensure best practices are the defaults: Newly added `If Controller` now uses by default Expression which is the most performing option.
> - Newly added JSR223 Test Element now cache compiled script by default if language used provides this feature.
> `Loop controller` and `ForEach Controller` now expose their current iteration as a variable named `__jm__<Name of your element>__idx` that you can use like this for example for a Loop Controller named `MyLoopController`:
>     ${__jm__MyLoopController__idx}
> . See Bug 61802 Cookies are now shown in View Results Tree during recording. They were previously always shown as empty. `Response Assertion` now allows you to customize assertion message and assert on Request Data.
> UX improvements
> JMeter now uses Darcula LAF by default Workbench has been dropped from UI, you can now use Non Test Elements as immediate children of Test Plan.
> Menu UX have been improved to make most used elements available more rapidly.
> HTTP(S) Test Script Recorder now allows you to name your transactions while recording in a more human readable way.
> - UX improvements made on, among the most notable : Module Controller informs user at least one Controller is required Function Helper Dialog (The wizard that helps using and testing functions) has been improved in many fields.
> Switch Controller trims text to avoid issues when a space is introduced before/after name Test Plan is now saved before running the test plan
> Functions
> New Function `__digest` provides easy computing of SHA-XXX, MDX hashes:
>     ${__digest(MD5,Apache JMeter 4.0 rocks !,,,)}
> will return `0e16c3ce9b6c9971c69ad685fd875d2b` New Function `__dateTimeConvert` provides easy conversion between date formats:
>     ${__dateTimeConvert(01 Jan 2017,dd MMM yyyy,dd/MM/yyyy,)}
> will return `01/01/2017` New Function `__changeCase` provides ability to switch to Upper / Lower / Capitalized cases
>     ${__changeCase(Avaro omnia desunt\, inopi pauca\, sapienti nihil,UPPER,)}
> will return `AVARO OMNIA DESUNT, INOPI PAUCA, SAPIENTI NIHIL` New Functions `__isVarDefined` and `__isPropDefined` provide testing of properties and variables availability
>     ${__isPropDefined(START.HMS)}
> will return `true`
>     ${__isVarDefined(JMeterThread.last_sample_ok)}
> will return `true`
> Scripting and Plugin Development
> You can now call `SampleResult#setIgnore()` if you don't want your sampler to be visible in results `JavaSamplerContext` used by `AbstractJavaSamplerClient` has been enhanced with new methods to easy plugin development. JMeter now distributes additional Maven sources and javadoc artifacts into Maven repository Plugins can now register listeners to be notified when a Test Plan is opened/closed
> Live Reporting and Web Report
> InfluxDB backend listener now allows you to add custom tags by adding them with prefix `TAG_`, see Bug 61794 In Web Report responseTime distribution graph is more precise Some bugfixes have been made on report generation, see Bug 61900 , Bug 61900 61956, Bug 61899 . Graphs Latency Vs Request and Response Time Vs Request did not exceed 1000 RPS due to Bug 61962
> Configuration of JMeter environment
> JVM settings for the JMeter start scripts can be placed in a separate file (`bin/setenv.sh` on Unix and `bin\setenv.bat` on Windows), that gets called on startup. The startup script itself does not have to be edited anymore.
> Incompatible changes
> - `Start time` and `End date` of Thread Group have been removed, see Bug 61549 In distributed testing, mode `Hold` has been removed. Use alternative and more efficient modes For 3rd party plugins, the following method in `org.apache.jmeter.gui.tree.JMeterTreeNode` has been dropped for migration to Java 9 (Bug 61529 )
>       public Enumeration<JMeterTreeNode> children()
> `tearDown Thread Group` will now run on stop and shutdown of a test by default. If you don't want this behaviour, uncheck `Run tearDown Thread Groups after shutdown of main threads` on `Test Plan` element, see Bug 61656 Properties `sampleresult.getbytes.headers_size` and `sampleresult.getbytes.body_real_size` have been dropped, see Bug 61587 JMeter will now save your test plan whenever you run it. This behaviour can be controlled by property `save_automatically_before_run`, see Bug 61731 Workbench element has been dropped, you now directly add `Non Test Element` as children of Test Plan. When loading a Test Plan that contains the element JMeter will move the `Mirror Server`, `Property Display` and HTTP(s) `Test Script Recorder` elements as direct children of Test Plan. For any other element, it will create a `Test Fragment` element called `Workbench Test Fragment and move the elements in it`. Following classes have been dropped (`org.apache.jmeter.functions.util.ArgumentEncoder`, `org.apache.jmeter.functions.util.ArgumentDecoder`), see Pull request #335 - In JMS Point-to-Point sampler, setting timeout to 0 will now mean infinite timeout while previously it would be switched to 2000 ms, see Bug 61829 When Assertions are at different scopes, they are executed starting with the most OUTER one to the most INNER one. See Bug 61846 JMeter now starts by default using English locale. This change is due to missing translations in many supported languages. You can change locale by modifying in jmeter and jmeter.bat (or preferably setenv.sh/setenv.bat) the `JVM_ARGS` system property values. We'd also be very grateful if you can contribute translations in supported languages. SwitchController now trims by default the content of switch to avoid issue related to unwanted spaces. See Bug 61771 JMeter JVM heap settings have changed from `-Xms512m -Xmx512m` to `-Xms1g -Xmx1g` Beanshell version has been upgraded to bsh-2.0b6 which introduces breaking changes and more strict parsing rules

> Known problems and workarounds
> - View Results Tree may freeze rendering large response particularly if this response has no spaces, see Bug 60816 . This is due to an identified Java Bug UI stuck when calling `JEditorPane.setText()` or `JTextArea.setText()` with long text without space. The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The numbers that appear to the left of the green box are the number of active threads / total number of threads, the total number of threads only applies to a locally run test, otherwise it will show `0` (see Bug 55510 ). Note that under some windows systems you may have this WARNING:
>       java.util.prefs.WindowsPreferences
>       WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
>       x80000002. Windows RegCreateKeyEx(…) returned error code 5.

> New and Noteworthy
> IMPORTANT CHANGES
> JMeter now requires Java 8. Ensure you use the most up to date version. JMeter logging has been migrated to SLF4J and Log4j 2. This affects configuration and 3rd party plugins, see below "Logging changes". Starting with JMeter version 3.2 the number of results in View Results Tree is limited by default to 500 entries. If you want more entries, you have to set the property `view.results.tree.max_results` to a higher value, or to `0`, if you don't want to impose any limit. You can set the property in bin/user.properties. More info might be found here.
> Core improvements
> - JMeter now provides a new BackendListener implementation that interfaces InfluxDB.
>   This implementation sends data using Asynchronous HTTP calls to InfluxDB through its HTTP API and give you the following graphs with annotations:
> - DNS Cache Manager now has a table to allow static host resolution.
> - JMS Publisher and Subscriber now allow reconnection on error with pause.
> Variables in JMS Publisher are now supported for all types of messages. Add the encoding type of the file to parse its content
> - XPath Extractor now allows extraction randomly, by index or for all matches.
> - Response Assertion now allows to work on Request Header, provides a "OR" combination and has a better cell renderer
> JMeter now uses Oracle Nashorn Javascript engine instead of Rhino. This provides a faster execution of Javascript. HTTP HC4 Implementation now provides preemptive Basic Auth enabled by default Embedded resources download in CSS has been improved to avoid useless repetitive parsing to find the resources An important work on code quality and code coverage with tests has been done since Sonar has been setup on the project. You can see Sonar report here.
> UX improvements
> - When running a Test, GUI is now more responsive and less impacting on memory usage thanks to a limitation on the number of Sample Results listeners hold and a rework of the way GUI is updated HTTP Request GUI has been simplified and provides more place for parameters and body.
> - HTTP(S) Test Script Recorder has been simplified and clarified.
> - A `replace` feature has been added to Search feature to allow replacement in some elements.
>   ReplaceAll does not do replacement on all elements, it does it on: - HeaderManager: Replacement in values - Http Request: Replacement in Arguments, Path and Host
> - View Results Tree now provides a more up to date Browser renderer which requires JavaFX. You can now add through a contextual menu think times, this will add think times between samplers and Transaction Controllers of selected node.
> - You can now apply a naming policy to children of a Transaction Controller. A default policy exists but you can implement your own through `org.apache.jmeter.gui.action.TreeNodeNamingPolicy` and configuring property `naming_policy.impl`
> - Sorting per column has been added to View Results in Table, Summary Report, Aggregate Report and Aggregate Graph elements.
> Report/Dashboard improvements
> - Statistics have been reorganized to clarify report:
> - It is now possible to customize APDEX thresholds per transaction based on regular expression or sample name. The below example will apply different thresholds for samples sample(\\d+), sampleA and scenarioB than default ones (500 and 1500 for satisfied and tolerated thresholds) declared:
>       jmeter.reportgenerator.apdex_satisfied_threshold=500
>       jmeter.reportgenerator.apdex_tolerated_threshold=1500
>       jmeter.reportgenerator.apdex_per_transaction=sample(\\d+):1000|2000;\
>           sampleA:3000|4000;\
>           scenarioB:5000|6000
> Documentation improvements
> PDF Documentations have been migrated and updated to HTML user manual
> Incompatible changes
> JMeter requires now at least a Java 8 version to run. JMeter logging has been migrated to SLF4J and Log4j 2, this involves changes in the way configuration is done. JMeter now relies on standard Log4j 2 configuration in file `log4j2.xml` See `Logging changes` section below for further details. The following jars have been removed after migration from LogKit to SLF4J (see Bug 60589 ): ApacheJMeter_slf4j_logkit.jar avalon-framework-4.1.4.jar commons-logging-1.2.jar excalibur-logger-1.1.jar logkit-2.0.jar The `commons-httpclient-3.1.jar` has been removed after drop of HC3.1 support(see Bug 60727 ) JMeter now sets through `-Djava.security.egd=file:/dev/urandom` the algorithm for secure random Process Sampler now returns error code 500 when an error occurs. It previously returned an empty value. In `org.apache.jmeter.protocol.http.sampler.HTTPHCAbstractImpl` two protected static fields (`localhost` and `nonProxyHostSuffixSize`) have been renamed to (`LOCALHOST` and `NON_PROXY_HOST_SUFFIX_SIZE`) to follow static fields naming convention JMeter now uses by default Oracle Nashorn engine instead of Mozilla Rhino for better performances. This should not have an impact unless you use some advanced features. You can revert back to Rhino by settings property `javascript.use_rhino=true`. You can read this migration guide for more details on Nashorn. See Bug 60672 Bug 60729 - The Random Variable Config Element now allows minimum==maximum. Previous versions logged an error when minimum==maximum and did not set the configured variable. Bug 60730 - The JSON PostProcessor now sets the `_ALL` variable (assuming `Compute concatenation var` was checked) even if the JSON path matches only once. Previous versions did not set the `_ALL` variable in this case. ### Removed elements or functions SOAP/XML-RPC Request has been removed as part of Bug 60727 . Use HTTP Request element as a replacement. See Building a WebService Test Plan Bug 60423 - Drop Monitor Results listener Drop deprecated class `org.apache.jmeter.protocol.system.NativeCommand` Drop deprecated class `org.apache.jmeter.protocol.http.config.gui.MultipartUrlConfigGui` Drop deprecated class `org.apache.jmeter.testelement.TestListener` Drop deprecated class `org.apache.jmeter.reporters.FileReporter` Drop deprecated class `org.apache.jmeter.protocol.http.modifier.UserSequence` Drop deprecated class `org.apache.jmeter.protocol.http.parser.HTMLParseError` Drop unused methods `org.apache.jmeter.protocol.http.control.HeaderManager#getSOAPHeader` and `org.apache.jmeter.protocol.http.control.HeaderManager#setSOAPHeader(Object)` `org.apache.jmeter.protocol.http.util.Base64Encode` has been deprecated, you can use `java.util.Base64` as a replacement ### Logging changes JMeter logging has been migrated to SLF4J and Log4j 2. This affects logging configuration and 3rd party plugins (if they use JMeter logging). The following sections describe what changes need to be made. #### Setting the logging level and log file The default logging level can be changed on the command-line using the `-L` parameter. Likewise the `-l` parameter can be used to change the name of the log file. However the `log_level` properties no longer work. The default logging levels and file name are defined in the `log4j2.xml` configuration file in the launch directory (usually `JMETER_HOME/bin`)
> If you need to change the level programmatically from Groovy code or Beanshell, you need to do the following:
>         import org.apache.logging.log4j.core.config.Configurator;
>         ⋮
>         final String loggerName = te.getClass().getName(); // te being a JMeter class
>         Configurator.setAllLevels(loggerName, Level.DEBUG);
> #### Changes to 3rd party plugin logging
> 3rd party plugins should migrate their logging code from logkit to slf4j. This is fairly easy and can be done by replacing:
>             import org.apache.jorphan.logging.LoggingManager;
>             import org.apache.log.Logger;
>             ⋮
>             private static final Logger log = LoggingManager.getLoggerForClass();
> By:
>             import org.slf4j.Logger;
>             import org.slf4j.LoggerFactory;
>             ⋮
>             private static final Logger log = LoggerFactory.getLogger(YourClassName.class);

> Known problems and workarounds
> - View Results Tree may freeze rendering large response particularly if this response has no spaces, see Bug 60816 . This is due to an identified Java Bug UI stuck when calling JEditorPane.setText() or JTextArea.setText() with long text without space. The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The numbers that appear to the left of the green box are the number of active threads / total number of threads, the total number of threads only applies to a locally run test, otherwise it will show `0` (see Bug 55510 ). Note that under some windows systems you may have this WARNING:
>       java.util.prefs.WindowsPreferences
>       WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
>       x80000002. Windows RegCreateKeyEx(…) returned error code 5.
> - The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore. You may encounter the following error:
>       java.security.cert.CertificateException: Certificates does not conform to algorithm constraints
>   if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature algorithm using MD2 (like md2WithRSAEncryption) or with a SSL certificate with a size lower than 1024 bits. This error is related to increased security in Java 8+. To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing the Java `jdk.certpath.disabledAlgorithms` property. Remove the MD2 value or the constraint on size, depending on your case. This property is in this file:
>       JAVA_HOME/jre/lib/security/java.security
> See Bug 56357 for details. Under Mac OSX Aggregate Graph will show wrong values due to mirroring effect on numbers. This is due to a known Java bug, see Bug JDK-8065373 The fix is to use JDK8_u45 or later. View Results Tree may fail to display some HTML code under HTML renderer, see Bug 54586 . This is due to a known Java bug which fails to parse "`px`" units in row/col attributes. See Bug JDK-8031109 The fix is to use JDK9 b65 or later (but be aware that Java 9 is not certified yet for JMeter). JTable selection with keyboard (SHIFT + up/down) is totally unusable with JAVA 7 on Mac OSX. This is due to a known Java bug JDK-8025126 The fix is to use JDK 8 b132 or later. # Version 3.1 Summary New and Noteworthy Incompatible changes Bug fixes Improvements Non-functional changes Known problems and workarounds Thanks
> New and Noteworthy
> Improve Report/Dashboard
> - The Dashboard has been improved with 3 new graphs and 1 summary table: Connect Time over Time graph :
> - Response Time Percentiles Over Time (successful responses) graph :
> - Response Time Overview graph :
> - Top 5 errors by Sampler table :
> - More details on errors in Errors table Average response time added to Statistics table :
> - Active Threads table now stacks threads :
> New Metrics
> A new `sent_bytes` metric has been introduced which reports the bytes sent to server. Another metric `connect_time` has been enabled by default in this version
> Handling Big responses
> JMeter is now able to handle in terms of metrics responses bigger than 2GB, limit has been increased to 9223372 TB. To handle such big responses, it can also now truncate part of the response to avoid overflooding memory. See `httpsampler.max_bytes_to_store_per_request` property.
> New function
> Introduce a new function `__groovy` that enables Groovy functions. This can be handy, as JavaScript can be quite slow (same for BeanShell), when used in highly concurrent test plans.
> Use Groovy as default for JSR-223 elements
> Groovy is now set as the default language for JSR-223 elements. If you want to use another of the supported language, you have to make an explicit choice.
> By default `Cache compiled script if available` is not checked by default although we advise you to check it and ensure you don't use `${varName}` syntax to access JMeter variables but `vars.get("varName")` instead.
> Formatted HTML source view in Results Tree View
> The HTML source code in the Results Tree View can now be viewed formatted. This is extremely useful, if the code of the webpage has been stripped of all superfluous whitespace.
> New formatted HTML source view
> Ability to update all timers in Test plan with a new property
> A new property `timer.factor=1.0f` has been introduced which allows you to multiply pause times computed by Gaussian, Uniform and Poisson Timers by it. This allows you to update Think Times from one place and let you gain productivity.
> Core improvements
> Various GUI and UX fixes Memory usage improvements JDBC Request is now able to return Blob/Clob and computes latency and connect time CSS Parsing introduced in 3.0 has been optimized by introduction of a parsing cache HTTP Request is now able to handle body in GET request, this is useful for Elastic Search requests for example.
> Documentation improvements
> Documentation review and improvements for easier startup New properties reference documentation section
> Incompatible changes
> A cache for CSS Parsing of URLs has been introduced in this version, it is enabled by default. It is controlled by property `css.parser.cache.size`. It can be disabled by setting its value to `0`. See Bug 59885 ThroughputController defaults have changed. Now defaults are Percent Executions which is global and no more per user. See Bug 60023 Since version 3.1, HTML report ignores empty `Transaction Controller` (possibly generated by `If Controller` or `Throughput Controller`) when computing metrics. This provides more accurate metrics Since version 3.1, Summariser ignores SampleResults generated by `Transaction Controller` when computing the live statistics, see Bug 60109 Since version 3.1, when using Stripped modes (by default `StrippedBatch` is used), response will be stripped also for failing SampleResults, you can revert this to previous behaviour by setting `sample_sender_strip_also_on_error=false` in `user.properties`, see Bug 60137 Since version 3.1, `jmeter.save.saveservice.connect_time` property value is `true`, meaning CSV file for results will contain an additional column containing connection time, see Bug 60106 Since version 3.1, Random Timer subclasses (Gaussian Random Timer, Uniform Random Timer and Poisson Random Timer) implement interface `org.apache.jmeter.timers.ModifiableTimer` Since version 3.1, if you don't select any language in JSR223 Test Elements, Apache Groovy language will be used. See Bug 59945 Since version 3.1, CSV DataSet now trims variable names to avoid issues due to spaces between variables names when configuring CSV DataSet. This should not have any impact for you unless you use space at the beginning or end of your variable names. See Bug 60221 Since version 3.1, HTTP Request is able when using HttpClient4 (default) implementation to handle responses bigger than `2147483647` Bytes, that is 2GB. To allow this two properties have been introduced: `httpsampler.max_bytes_to_store_per_request` (defaults to 10MB) will control what is held in memory. By default JMeter will only keep in memory the first 10MB of a response. If you have responses larger than this value and use assertions that are after the first 10MB, then you must increase this value `httpsampler.max_buffer_size` will control the buffer used to read the data. Previously JMeter used a buffer equal to Content-Length header which could lead to failures and make JMeter less resistant to faulty applications, but note this may impact response times and give slightly different results than previous versions if your application returned a Content-Length header higher than current default value (65KB) See Bug 53039 ### Deprecated and removed elements or functions
> These elements do not appear anymore in the menu, if you need them modify `not_in_menu` property. The JMeter team advises not to use them anymore and migrate to their replacement.
> Bug 60222 - Remove deprecated elements Distribution Graph, Spline Visualizer Bug 60224 - Deprecate `Monitor Results` listener. It will be dropped in next version. Bug 60323 - Deprecate BSF Elements (Use JSR223 Elements instead). They will probably be dropped in N+2 version. The following elements are deprecated: `BSF Sampler` `BSF Listener` `BSF Assertion` `BSF Timer` `BSF PreProcessor` `BSF PostProcessor` Bug 60225 - Drop deprecated `__jexl` function, jexl support in BSF and dependency on `commons-jexl-1.1.jar`. This function can be easily replaced with `__jexl3` function Bug 60268 - Drop org.apache.jmeter.gui.action.Analyze and deprecate org.apache.jmeter.reporters.FileReporter (will be removed in next version)

For this release we want to give special thanks to the following reporters for the clear reports and tests made after our fixes: Apologies if we have omitted anyone else.
> Known problems and workarounds
> - The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The numbers that appear to the left of the green box are the number of active threads / total number of threads, the total number of threads only applies to a locally run test, otherwise it will show `0` (see Bug 55510 ). Note that there is a bug in Java on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
>        [java] WARNING: Couldn't flush user prefs:
>        java.util.prefs.BackingStoreException:
>        java.lang.IllegalArgumentException: Not supported: indent-number
> - This does not affect JMeter operation. This issue is fixed since Java 7b05. Note that under some windows systems you may have this WARNING:
>       java.util.prefs.WindowsPreferences
>       WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
>       x80000002. Windows RegCreateKeyEx(…) returned error code 5.
> - The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore. With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry. This is a known Java bug, see Bug JDK-8000629. A workaround is to use a Java 7 update 40 runtime which fixes this issue. You may encounter the following error:
>       java.security.cert.CertificateException: Certificates does not conform to algorithm constraints
>   if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature algorithm using MD2 (like md2WithRSAEncryption) or with a SSL certificate with a size lower than 1024 bits. This error is related to increased security in Java 7 version u16 (MD2) and version u40 (Certificate size lower than 1024 bits), and Java 8 too. To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing the Java `jdk.certpath.disabledAlgorithms` property. Remove the MD2 value or the constraint on size, depending on your case. This property is in this file:
>       JAVA_HOME/jre/lib/security/java.security
> See Bug 56357 for details. Under Mac OSX Aggregate Graph will show wrong values due to mirroring effect on numbers. This is due to a known Java bug, see Bug JDK-8065373 The fix is to use JDK7_u79, JDK8_u45 or later. View Results Tree may fail to display some HTML code under HTML renderer, see Bug 54586 . This is due to a known Java bug which fails to parse "`px`" units in row/col attributes. See Bug JDK-8031109 The fix is to use JDK9 b65 or later. JTable selection with keyboard (SHIFT + up/down) is totally unusable with JAVA 7 on Mac OSX. This is due to a known Java bug JDK-8025126 The fix is to use JDK 8 b132 or later. # Version 3.0 Summary New and Noteworthy Known bugs Incompatible changes Bug fixes Improvements Non-functional changes Thanks
> New and Noteworthy
> Test plan creation and debugging improvements
> New Search Feature in View Results Tree to allow searching for text / regexp in Request/Responses/Headers/Cookies/… This will ease correlation and Test plans creation
> New JSON Post Processor to better extract data from JSON content using user friendly JSON-PATH syntax
> JSON is now a first class citizen in JMeter with the introduction of a new JSONPath post processor. This post processor is very similar to Regular Expression Post Processor but is well suited for JSON code. It is based on Jayway JSON Path library
> New validation feature, in one click run a selection of Thread Groups with user, no pause and iteration
> JSR223 Test Elements do not require a Cache Compilation Key anymore
> Just check `Cache compiled script if available` checkbox and the elements (Pre-Processor, Post-Processor, Assertions, Listeners, …) will pre-compile the script and cache the compiled code if the underlying language supports it
> Nashorn can now be used as Javascript engine providing better performance and easier usage
> To enable Nashorn, you need to set in `user.properties`:
>     javascript.use_rhino=false
> Nashorn can be used with Java 8 in the following elements: IfController JSR223 Test elements with `javascript` language selected `__javaScript` function
> Jexl3 has been integrated. It provides new scripting features and much better documentation
> JEXL3 can now be used thanks to a new function `__jexl3`. JEXL is a language very similar to JSTL.
> Simplified HTTP Request UI
> A new "`Advanced`" tab has been added to HTTP Request to simplify configuration. The file upload feature has been moved into a dedicated tab. This increases the space available for parameters in UI and simplifies the UX.
> HTTP Request Defaults improvements
> You can now configure Source Address (IP Spoofing like feature) and "`Save response as MD5 hash`" in Advanced Tab
> Reporting improvements
> New Reporting Feature generating dynamic Graphs in HTML pages (APDEX, Summary report and Graphs)
> - A dynamic HTML report can now be generated either at the end of a load test or from a result file whenever you want. See Generating dashboard for more details. This report provides the following metrics: APDEX (Application Performance Index) table that computes the APDEX based on configurable values for tolerated and satisfied thresholds A request summary graph showing the Success and failed transaction percentage:
> - A Statistics table providing in one table a summary of all metrics per transaction including 3 configurable percentiles :
> - An error table providing a summary of all errors and their proportion in the total requests :
> - - Zoomable chart where you can check/uncheck every transaction to show/hide it for: Response times Over Time :
>   - Bytes throughput Over Time :
>   - Latencies Over Time :
>   - Hits per second :
>   - Response codes per second :
>   - Transactions per second :
>   - Response Time vs Request per second :
>   - Latency vs Request per second :
>   - Response times percentiles :
>   - Active Threads Over Time :
>   - Times vs Threads :
>   - Response Time Distribution :
> GraphiteBackendListener has a new Server Hits metric
> Summariser displays a more readable duration
> Now duration are display in the format `hours:minutes:seconds`

> BackendListener now allows you to define sampler list as a regular expression
> You can now use a regular expression to select the samplers you want to filter. Use parameter: `useRegexpForSamplersList=true` and put a regex in parameter `samplersList`
> Protocols and Load Testing improvements
> Migration to HttpClient 4.5.2 has been started. Although not completely finished, it improves many areas in JMeter
> Migration to HttpClient 4.5.2 improves the following fields of JMeter: Support of recent RFC like HTTP State Management Mechanism RFC-6265 for Cookies, you should use now `HC4CookieHandler` in HTTP Cookie Manager component and select `standard` Cookie policy Server Name Indication (SNI) support for HttpClient4 implementation Improved and better performing validation mechanism for Stale connections and Keep-Alive management, see properties `httpclient4.validate_after_inactivity` and `httpclient4.time_to_live` Many bug fixes since previous version 4.2.6 used in JMeter 2.13, see HttpClient 4.5.X release notes Better support of HTTP RFC 2616 / RFC 7230 and fixes to issues with `deflate` compression management
> Parallel Downloads is now realistic and scales much better:
> Parsing of CSS imported files (through `@import`) or embedded resources (background, images, …) Lazy initialization of SSL context: For 15 Threads 138% more sampling in 5 minutes for HTTP only tests. Gain increases as number of threads increases Rework of Connection management for Parallel Download: This better simulates current browser behaviour and improves throughput. For 15 Threads 135% extra samples in 5 minutes. Reuse of Threads used for Parallel downloads through a ThreadPool: This improves throughput and increases JMeter scalability for such tests Total of 750% more throughput found on test with 15 threads, the more threads you have the more the gain You can now compute and store just the MD5 of embedded resources instead of storing the entire response, this can be done by setting the property `httpsampler.embedded_resources_use_md5=true`
> Introduction of Sample Timeout feature
> This new Sample Timeout Pre-Processor allows you to apply a Timeout on the elements that are in its scope. In the screenshot below the 10 second timeout applies to the `Debug Sampler` and `HTTP Request` elements.
> JDBC request now uses DBCP2 pool
> JDBC Request and JDBC Connection Configuration have been updated to replace old Excalibur Pool by Apache Commons DBCP2 pool. As a consequence properties have been migrated to equivalent when available and UI has been updated. Note that unlike Excalibur, Commons DBCP uses the validation query when creating the pool. So make sure the query is valid. The default query suits many databases, but not all - for example Oracle requires '`SELECT 1 FROM DUAL`' or similar.
> UX Improvements:
> Better display in HiDPI screens
> See JMeter with a HiDPI screen on Linux or Windows in Hints and Tips section in user manual
> New Icon look and Logo
> JMeter has a new Logo created by Felix Schumacher. Icons have also been refreshed to give a more modern style and make them more meaningful
> Lots of fixes of annoying little bugs
> Around 40 UI fixes have been made to either fix buggy, confusing behaviour or simplify usage by not allowing incompatible options to be selected
> Improved Thread Group UI and related actions (, , )
> Creating and testing a Test Plan before Load Test has been much simplified by allowing you to only start a selection of Thread Group, start them without applying Timers (thus gaining time) or start them using a new Validation mode. This validation mode allows you to start a Thread Group (without modifying it) with 1 thread, 1 iteration and without applying timers. This validation mode can be customized.
> New shortcuts
> Add most used elements (Ctrl + 0 … Ctrl + 9), configurable through `gui.quick_XXX` properties Shortcuts to expand nodes
> Core improvements
> Configuration simplification with better defaults
> Default values for many properties have been modified to make JMeter configuration optimal Out of the box. Read "Incompatible changes" section for more details.
> Apache Groovy bundled with JMeter
> Apache Groovy, the well-known JVM scripting language, is now bundled with Apache JMeter in lib folder. This allows you to use it immediately through JSR223 Elements by selecting the Groovy language.
> Superfluous and old properties removed
> Old properties that existed to maintain backward compatibility or to offer some superfluous customization have been removed. Read "Incompatible changes" section to see which properties have been removed.
> Code and documentation improvements
> Migration to Java7 source code and use of its syntactic sugar Major code cleanups Full review of documentation and improvement both in content and presentation
> Improvements to unit tests
> Migration of many tests to JUnit 4 Better management of Headless tests More Unit Tests
> Dependencies refresh
> Deprecated Libraries dropped or replaced by up to date ones: Excalibur replaced by commons-dbcp htmllexer, htmlparser removed soap removed jdom removed
> Slf4j can now be used within Plugins and core code
> You can now use SLF4J logging wrapper in your custom plugins or `org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient` subclasses.
> Incompatible changes
> - Since version 3.0, Groovy-2.4.6 is bundled with JMeter (`lib` folder), ensure you remove old version or referenced versions through properties `search_paths` or `user.classpath` Since version 3.0, `jmeter.save.saveservice.assertion_results_failure_message` property value is true, meaning CSV file for results will contain an additional column containing assertion result response message, see Bug 58978 Since version 3.0, `jmeter.save.saveservice.print_field_names` property value is true, meaning CSV file for results will contain field names as first line in CSV, see Bug 58991 Since version 3.0, `jmeter.save.saveservice.idle_time` property value is true, meaning CSV/XML result files will contain an additional column containing idle time between samplers, see Bug 57182 In RandomTimer class, protected instance `timer` field has been replaced by `getTimer()` protected method, this is related to Bug 58100 . This may impact 3rd party plugins. Since version 3.0, you can use Nashorn Engine (default javascript engine is Rhino) under Java8 for Elements that use Javascript Engine (`__javaScript`, `IfController`). If you want to use it, use property `javascript.use_rhino=false`, see Bug 58406 .
>   Note: in a future version, we will switch to Nashorn by default. Users are encouraged to report any issue related to using Nashorn instead of Rhino.
> - Since version 3.0, JMS Publisher will reload contents of file if Message source is "`From File`" and the "`Filename`" field changes (e.g. if it uses a variable that has changed) `org.apache.jmeter.gui.util.ButtonPanel` has been removed, if you use it in your 3rd party plugin or custom development ensure you update your code. See Bug 58687 Property `jmeterthread.startearlier` has been removed. See Bug 58726 Property `jmeterengine.startlistenerslater` has been removed. See Bug 58728 Property `jmeterthread.reversePostProcessors` has been removed. See Bug 58728 Property `jmeter.toolbar.display` has been removed, the toolbar is now always displayed. See Bug 59236 Property `jmeter.errorscounter.display` has been removed, the errors/warnings counter is now always displayed. See Bug 59236 Property `xml.parser` has been removed, it is not used anymore as `org.apache.jmeter.util.JMeterUtils#getXMLParser` has been deprecated and is not used either. See Bug 59236 Summariser listener now shows the duration in the format `HH:mm:ss` (Hour:Minute:Second), it previously showed the duration in seconds. See Bug 58776 `org.apache.jmeter.protocol.http.visualizers.RequestViewHTTP.getQueryMap` signature has changed, if you use it ensure you update your code. See Bug 58845 JMS Subscriber will consider a sample to be an error if the number of received messages is not equal to expected number of messages. It previously considered a sample OK if at least 1 message was received. See Bug 58980 Since version 3.0, HTTP(S) Test Script recorder defaults to using port `8888` (as configured when using Recording Template). See Bug 59006 Since version 3.0, the parser for embedded resources (replaced since 2.10 by Lagarto based implementation) which relied on the htmlparser library (HtmlParserHTMLParser) has been dropped along with its dependencies. Since version 3.0, support for reading old Avalon format JTL (result) files has been removed, see Bug 59064 Since version 3.0, the default property value for `http.java.sampler.retries` has been changed to `0` (no retry by default) to align it with the behaviour of HttpClient4.
>   Note also that its meaning has changed: before 3.0, `http.java.sampler.retries=1` meant `No Retry` (i.e. total tries = 1), since 3.0 `http.java.sampler.retries=1` means `1` retry. (Note: this only applies to the Java HTTP Sampler)
> See Bug 59103 Since 3.0, the following deprecated classes have been dropped org.apache.jmeter.protocol.http.modifier.UserParameterXMLContentHandler org.apache.jmeter.protocol.http.modifier.UserParameterXMLErrorHandler org.apache.jmeter.protocol.http.modifier.UserParameterXMLParser `httpsampler.await_termination_timeout` has been replaced by `httpsampler.parallel_download_thread_keepalive_inseconds` which is now the keep alive time for the parallel download threads (in seconds). JDBC Request has been updated to use commons-dbcp2, since then the behaviour is slightly different, ensure you have a correct "Validation Query" for your database. See Bug 58786 The following jars have been removed: excalibur-datasource-2.1.jar (see Bug 59156 ) excalibur-instrument-1.0.jar (see Bug 58786 ) excalibur-pool-api-2.1.jar (see Bug 58786 ) excalibur-pool-impl-2.1.jar (see Bug 58786 ) excalibur-pool-instrumented-2.1.jar (see Bug 58786 ) htmllexer-2.1.jar (see Bug 59037 ) htmlparser-2.1.jar (see Bug 59037 ) soap-2.3.1.jar jdom-1.1.3.jar (see Bug 59156 ) Maximum number of redirects allowed by JMeter is now 20, it was previously 5. This can be changed with the property `httpsampler.max_redirects`. See Bug 59382 ### Deprecated and removed elements MongoDB elements (MongoDB Source Config, MongoDB Script) have been deprecated and will be removed in the next version of JMeter. They do not appear anymore in the menu, if you need them modify `not_in_menu` property. The JMeter team advises not to use them anymore. See Bug 58772 WebService(SOAP) Request and HTML Parameter Mask which were deprecated in 2.13 version, have now been removed following our deprecation strategy. Classes and properties which were only used by those elements have been dropped: `org.apache.jmeter.protocol.http.util.DOMPool` `org.apache.jmeter.protocol.http.util.WSDLException` `org.apache.jmeter.protocol.http.util.WSDLHelper` Property `soap.document_cache` JAR soap-2.3.1 has been also removed `__jexl` function (i.e. JEXL 1) has been deprecated and will be removed in next version. See Bug 58903 Spline Visualizer listener and Distribution Graph listener have been deprecated and will be removed in the next version of JMeter. They do not appear anymore in the menu, if you need them modify `not_in_menu` property. JMeter team advises not to use them anymore. See Bug 58791

> Known problems and workarounds
> - The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The numbers that appear to the left of the green box are the number of active threads / total number of threads, the total number of threads only applies to a locally run test, otherwise it will show `0` (see Bug 55510 ). Note that there is a bug in Java on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
>        [java] WARNING: Couldn't flush user prefs:
>        java.util.prefs.BackingStoreException:
>        java.lang.IllegalArgumentException: Not supported: indent-number
> - This does not affect JMeter operation. This issue is fixed since Java 7b05. Note that under some windows systems you may have this WARNING:
>       java.util.prefs.WindowsPreferences
>       WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
>       x80000002. Windows RegCreateKeyEx(…) returned error code 5.
> - The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore. With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry. This is a known Java bug, see Bug JDK-8000629. A workaround is to use a Java 7 update 40 runtime which fixes this issue. You may encounter the following error:
>       java.security.cert.CertificateException: Certificates does not conform to algorithm constraints
>   if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature algorithm using MD2 (like md2WithRSAEncryption) or with a SSL certificate with a size lower than 1024 bits. This error is related to increased security in Java 7 version u16 (MD2) and version u40 (Certificate size lower than 1024 bits), and Java 8 too. To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing the Java `jdk.certpath.disabledAlgorithms` property. Remove the MD2 value or the constraint on size, depending on your case. This property is in this file:
>       JAVA_HOME/jre/lib/security/java.security
> See Bug 56357 for details. Under Mac OSX Aggregate Graph will show wrong values due to mirroring effect on numbers. This is due to a known Java bug, see Bug JDK-8065373 The fix is to use JDK7_u79, JDK8_u45 or later. View Results Tree may fail to display some HTML code under HTML renderer, see Bug 54586 . This is due to a known Java bug which fails to parse "`px`" units in row/col attributes. See Bug JDK-8031109 The fix is to use JDK9 b65 or later. JTable selection with keyboard (SHIFT + up/down) is totally unusable with JAVA 7 on Mac OSX. This is due to a known Java bug JDK-8025126 The fix is to use JDK 8 b132 or later. # Version 2.13 Summary New and Noteworthy Known bugs Incompatible changes Bug fixes Improvements Non-functional changes Thanks
> New and Noteworthy
> New Elements
> New Async BackendListener with Graphite implementation
> A new Async BackendListener has been added to allow sending result data to a backend listener. JMeter ships with a GraphiteBackendListenerClient that allows sending results to a Graphite server using Pickle or Plaintext protocols. You can implement your own backend by extending AbstractBackendListenerClient. This backend could be a database (JDBC), a Message Oriented Middleware (JMS), a Webservice or anything you want.
> This is the kind of Live Dashboard you can obtain using Grafana and InfluxDB Read this for more details.
> Grafana dashboard
> Core Improvements
> New connect time metric
> Starting with this version a new metric called connectTime has been added. It represents the time to establish connection. By default it is not saved to CSV or XML, to have it saved add to user.properties: `jmeter.save.saveservice.connect_time=true`
> Aggregate Graph and Report
> The listeners Aggregate Graph and Aggregate Report previously showed only the 90 percentile (historical behavior), the 95 percentile and the 99 percentile have been added and are customizable. To setup the percentiles value you want, add to user.properties: `aggregate_rpt_pct1=90 aggregate_rpt_pct2=95 aggregate_rpt_pct3=99`
> HTTP(S) Test Script Recorder
> Now component is able to detect authentication schemes and automatically adds a pre-configured HTTP Authorization Manager with the correct Mechanism.
> HTTP Request
> The CalDAV verbs (Calendar extensions to WebDAV) REPORT and MKCALENDAR have been added in the HTTP Request sampler.
> JDBC Request
> The ResultSet can be get as a object, this allows to handle more easily the results after in BeanShell, JSR223 scripts, …
> Distributed Testing
> To allow better usage of Distributed Testing in the cloud, retry behaviour has been added when starting test on servers. Read this for more details.
> Distributed Testing performance
> Since JMeter 2.13, Stripping modes (StrippingBatch being the default mode) now also strip responses from SubResults improving consumed network bandwidth.
> Documentation refresh
> A new style for website (responsive and more up to date) has been created by Felix Schumacher. Documentations have been refreshed particularly: Building a Webservice Test Plan Best Practices Help! My boss wants me to load test our application!
> GUI Improvements
> Module Controller
> The Module Controller now shows the target controller in a tree view (instead of combo list).
> Toolbar
> JMeter's toolbar has been refreshed for some icons (start, toggle, etc.). Three sizes are now available for the icons: 22x22, 32x32 and 48x48. The toolbar with 22x22 pixels icons
> The toolbar with 32x32 pixels icons
> The toolbar with 48x48 pixels icons
> HTTP(S) Test Script Recorder
> If your Test Plan does not contains a Recording Controller, a new warning message will appear if the HTTP(S) Test Script Recorder is configured to send the samples into a Recording Controller.
> Incompatible changes
> Since 2.13, Aggregate Graph, Summary Report and Aggregate Report now export percentages to %, before they exported the decimal value which differed from what was shown in GUI Third party plugins may be impacted by fix of Bug 57586 , ensure that your subclass of HttpTestSampleGui implements ItemListener if you relied on parent class doing so. Report package has been removed, `ApacheJMeter_report.jar` is not generated anymore as a consequence, see Bug 57269

A workaround is to use a Java 7 update 40 runtime which fixes this issue. You may encounter the following error: java.security.cert.CertificateException: Certificates does not conform to algorithm constraints if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature algorithm using MD2 (like md2WithRSAEncryption) or with a SSL certificate with a size lower than 1024 bits. This error is related to increased security in Java 7 version u16 (MD2) and version u40 (Certificate size lower than 1024 bits), and Java 8 too. To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing the Java jdk.certpath.disabledAlgorithms property.

> New and Noteworthy
> Java 8 support
> Now, JMeter 2.12 is compliant with Java 8.
> New Elements
> Critical Section Controller
> The Critical Section Controller allow to serialize the execution of a section in your tree. Only one instance of the section will be executed at the same time during the test.
> DNS Cache Manager
> The new configuration element DNS Cache Manager(see Bug 56841 ) improves the testing of: CDN (Content Delivery Network) DNS load balancing. Load Balancers like Amazon Elastic Load Balancer
> Core Improvements
> Smarter Recording of Http Test Plans
> - Test Script Recorder has been improved in many ways Better matching of Variables in Requests, making Test Script Recorder variabilize your sampler during recording more versatile Ability to filter from View Results Tree the Samples that are excluded from recording, this lets you concentrate on recorded Samplers analysis and not bother with useless Sample Results
> Better defaults for recording, since this version Recorder will number created Samplers letting you find them much easily in View Results Tree. Grouping of Samplers under Transaction Controller will be smarter making all requests emitted by a web page be children as new Transaction Controller
> Support of Webdav requests
> You can now test against WebDav server using HttpClient4 Implementation of Http Request
> Better handling of embedded resources
> When download embedded resources is checked, JMeter now uses User Agent header to download or not resources embedded within conditional comments as per About conditional comments.
> Ability to customize Cache Manager (Browser cache simulation) handling of cached resources
> You can now configure the behaviour of JMeter when a resource is found in Cache, this can be controlled with cache_manager.cached_resource_mode property
> JMS Publisher / JMS Point-to-Point
> Add JMSPriority and JMSExpiration fields for these samplers.
> Mail Reader Sampler
> You can now specify the number of messages that want you retrieve (before all messages were retrieved). In addition, you can fetch only the message header now.
> SMTP Sampler
> Adding the Connection timeout and the Read timeout to the SMTP Sampler.
> Synchronizing Timer
> Adding a timeout to define the maximum time to waiting of the group of virtual users.
> Performance improvements
> A big improvement in performances of Functions has been made by lifting useless synchronization. It concerns all functions except __StringFromFile, __XPath and __BeanShell, see Bug 57114 __jexl2 performances have been improved to avoid contention point, see Bug 56708
> GUI Improvements
> Undo/Redo support
> Undo / Redo has been introduced and allows user to undo/redo changes made on Test Plan Tree. This feature (ALPHA MODE) is disabled by default, to enable it set property undo.history.size=25
> View Results Tree
> Improve the ergonomics of View Results Tree by changing placement of Renderers and allowing custom ordering (with the property view.results.tree.renderers_order).
> Response Time Graph
> Adding the ability for the Response Time Graph listener to save/restore format its settings in/from the jmx file.
> Log Viewer
> Starting with this version, the last lines of JMeter's log file (jmeter.log) can be viewed directly in GUI by clicking on Warning icon in the upper right corner. This will unfold the Log Viewer panel and show logs.
> File Opening
> Now, "Open File dialog" uses last opened file folder as start folder, see Bug 52707

> Since JMeter 2.12, active threads in all thread groups and active threads in current thread group are saved by default to CSV or XML results, see Bug 57025 . This is usually the expected behaviour as you want to have the number of running threads during the test. But if you want to revert to previous behaviour, set property jmeter.save.saveservice.thread_counts=false Since JMeter 2.12, Mail Reader Sampler will show 1 for number of samples instead of number of messages retrieved, see Bug 56539 Since JMeter 2.12, when using Cache Manager, if resource is found in cache no SampleResult will be created, in previous version a SampleResult with empty content and 204 return code was returned, see Bug 54778 . You can choose between different ways to handle this case, see `cache_manager.cached_resource_mode` in `jmeter.properties`. Since JMeter 2.12, Log Viewer will no more clear logs when closed and will have logs available even if closed. See Bug 56920 .

> New and Noteworthy
> HTTP(S) Test Script Recorder improvements
> Following improvements have been made since major changes introduced in JMeter 2.10 on HTTP(S) Test Script Recorder: Better detection of missing or invalid configuration of keytool utility New system property `keytool.directory` (see `system.properties`) lets you configure directory containing keytool in case on non-standard installation
> JMS Publisher/Point to Point : Add ability to set typed values in JMS header properties
> In the samplers JMS Publisher and JMS Point-to-Point, you can now set up the class of values for the JMS header properties. Previously only String was possible.
> View Results Tree : Add an XPath Tester
> In View Results Tree listener, a new XPath tester can be used to test XPATH expressions.
> Ability to choose the client alias for the cert key in JsseSslManager such that Mutual SSL auth testing can be made more flexible
> When testing client based certificate authentications you have now better control on certificate you use through a new field "Variable name holding certificate alias", this field lets you select the certificate you want to send to server to authenticate. You can use a CSV Data Set as a holder for the variable value.
> Add a "Save as Test Fragment" option
> In the file menu, a new option allow to save a group of elements as a Test fragment.
> Summariser is be enabled by default in Non GUI mode
> When you run JMeter from command line, now JMeter displays some statistics from the Summariser mode.
> Transaction Controller:Change default property "Include duration of timer…" for newly created element
> Starting from 2.11, Transaction Controller is configured by default to exclude processing time of pre/post processors as long as timers pause.
> Known bugs
> - The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see Bug 52496 ). A workaround is to add a sampler at the same level as (or superior to) the If Controller. For example a Test Action sampler with 0 wait time (which doesn't generate a sample), or a Debug Sampler with all fields set to False (to reduce the sample size). The numbers that appear to the left of the green box are the number of active threads / total number of threads, the total number of threads only applies to a locally run test, otherwise it will show 0 (see Bug 55510 ). Note that there is a bug in Java on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
>        [java] WARNING: Couldn't flush user prefs:
>        java.util.prefs.BackingStoreException:
>        java.lang.IllegalArgumentException: Not supported: indent-number
> This does not affect JMeter operation. This issue is fixed since Java 7b05. With Java 1.6 and Gnome 3 on Linux systems, the JMeter menu may not work correctly (shift between mouse's click and the menu). This is a known Java bug (see Bug 54477 ). A workaround is to use a Java 7 runtime (OpenJDK or Oracle JDK). With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry. This is a known Java bug, see Bug JDK-8000629. A workaround is to use a Java 7 update 40 runtime which fixes this issue.
> Incompatible changes
> When creating a new Transaction Controller, property "Include duration of timer and pre-post processors in generated sample" will be unchecked starting from version 2.11 In Non GUI mode, since 2.11 summariser is enabled with a 30 seconds frequency JMeter is more lenient with redirect handling and relaxes on RFC2616 by allowing relative locations. See property "`jmeter.httpclient.strict_rfc2616`" in `jmeter.properties` to change this behaviour, see Bug 55717 When creating a new Response Assertion, property "Pattern Matching Rules" now defaults to Substring starting from version 2.11

See updated documentation: HTTP(S) Test Script Recorder Redirection are now more smartly detected by HTTP Proxy Server, see Bug 55531 Many fixes on edge cases with HTTPS have been made, see Bug 55502 , Bug 55504 , Bug 55506 Many encoding fixes have been made, see Bug 54482 , Bug 54142 , Bug 54293
> You can now load test MongoDB through new MongoDB Source Config
> Kerberos authentication has been added to Auth Manager
> Device can now be used in addition to source IP address
> You can now do functional testing of MongoDB scripts through new MongoDB Script
> Timeout has been added to OS Process Sampler
> Query timeout has been added to JDBC Request
> New functions (__urlencode and __urldecode) are now available to encode/decode URL encoded chars

> See jmeter property: `jmeterengine.force.system.exit`
> HttpSampler now allows DELETE Http Method to have a body (works for HC4 and HC31 implementations). This allows for example to test Elastic Search APIs
> 2 implementations of HtmlParser have been added to improve Embedded resources parsing
> You can choose the implementation to use for parsing Embedded resources in HTML pages: See jmeter.properties and look at property "htmlParser.className". org.apache.jmeter.protocol.http.parser.LagartoBasedHtmlParser for optimal performances org.apache.jmeter.protocol.http.parser.JSoupBasedHtmlParser for most accurate parsing and functional testing
> Distributed testing has been improved
> - Number of threads on each node are now reported to controller.
> Performance improvement on BatchSampleSender(Bug 55423 ) Addition of 2 SampleSender modes (StrippedAsynch and StrippedDiskStore), see jmeter.properties
> ModuleController has been improved to better handle changes to referenced controllers
> Improved class loader configuration, see
> New property "plugin_dependency_paths" for plugin dependencies Properties "search_paths", "user.classpath" and "plugin_dependency_paths" now automatically add all jars from configured directories
> Best-practices section has been improved, ensure you read it to get the most out of JMeter
> See Best Practices
> GUI and ergonomy Improvements
> New Templates feature that allows you to create test plan from existing template or merge template into your Test Plan
> Workbench can now be saved
> Syntax color has been added to scripts elements (BeanShell, BSF, and JSR223), MongoDB and JDBC elements making code much more readable and allowing UNDO/REDO through CTRL+Z/CTRL+Y
> BSF Sampler with syntax color
> JSR223 Pre Processor with syntax color

> ##### Currently French has all its labels translated. Other languages are partly translated, feel free to contribute translations by reading Localisation (Translator's Guide)
> Moving elements in Test plan has been improved in many ways
> ##### Drag and drop of elements in Test Plan tree is now much easier and possible on multiple nodes
> Note that due to this bug in Java, you cannot drop a node after last node. The workaround is to drop it before this last node and then Drag and Drop the last node before the one you just dropped. ##### New shortcuts have been added to move elements in the tree. (alt + Arrow Up) and (alt + Arrow Down) move the element within the parent node (alt + Arrow Left) and (alt + Arrow Right) move the element up and down in the tree depth
> Response Time Graph Y axis can now be scaled
> JUnit Sampler gives now more details on configuration errors
> Known bugs
> - The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see Bug 52496 ). A workaround is to add a sampler at the same level as (or superior to) the If Controller. For example a Test Action sampler with 0 wait time (which doesn't generate a sample), or a Debug Sampler with all fields set to False (to reduce the sample size). Webservice sampler does not consider the HTTP response status to compute the status of a response, thus a response 500 containing a non empty body will be considered as successful, see Bug 54006 . To workaround this issue, ensure you always read the response and add a Response Assertion checking text inside the response. The numbers that appear to the left of the green box are the number of active threads / total number of threads, these only apply to a locally run test; they do not include any threads started on remote systems when using client-server mode, (see Bug 54152 ). Note that there is a bug in Java on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
>        [java] WARNING: Couldn't flush user prefs:
>        java.util.prefs.BackingStoreException:
>        java.lang.IllegalArgumentException: Not supported: indent-number
> This does not affect JMeter operation. This issue is fixed since Java 7b05. With Java 1.6 and Gnome 3 on Linux systems, the JMeter menu may not work correctly (shift between mouse's click and the menu). This is a known Java bug (see Bug 54477 ). A workaround is to use a Java 7 runtime (OpenJDK or Oracle JDK). With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry. This is a known Java bug, see Bug JDK-8000629. A workaround is to use a Java 7 update 40 runtime which fixes this issue.
> Incompatible changes
> SMTP Sampler now uses eml file subject if subject field is empty With this version autoFlush has been turned off on PrintWriter in charge of writing test results. This results in improved throughput for intensive tests but can result in more test data loss in case of JMeter crash (extremely rare). To revert to previous behaviour set `jmeter.save.saveservice.autoflush` property to `true`. Shortcut for Function Helper Dialog is now CTRL+SHIFT+F1 (CMD + SHIFT + F1 for Mac OS). The original key sequence (Ctrl+F1) did not work in some locations (it is consumed by the Java Swing ToolTipManager). It was therefore necessary to change the shortcut. Webservice (SOAP) Request has been removed by default from GUI as Element is deprecated. (Use HTTP Request with Body Data, see also the Template Building a SOAP Webservice Test Plan), if you need to show it, see property `not_in_menu` in jmeter.properties Transaction Controller now sets Response Code of Generated Parent Sampler (if Generated Parent Sampler is checked) to response code of first failing child in case of failure of one of the children, in previous versions Response Code was empty. In previous versions, IncludeController could run Test Elements located inside a Thread Group, this behaviour (which was not documented) could result in weird behaviour, it has been removed in this version (see Bug 55464 ). The correct way to include Test Elements is to use Test Fragment as stated in documentation of Include Controller. The retry count for the HttpClient 3.1 and HttpClient 4.x samplers has been changed to 0. Previously the default was 1, which could cause unexpected additional traffic. Starting with this version, the HTTP(S) Test Script Recorder tries to detect when a sample is the result of a previous redirect. If the current response is a redirect, JMeter will save the redirect URL. When the next request is received, it is compared with the saved redirect URL and if there is a match, JMeter will disable the generated sample. To revert to previous behaviour, set the property `proxy.redirect.disabling=false` Starting with this version, in HTTP(S) Test Script Recorder if Grouping is set to Put each group in a new Transaction Controller, the Recorder will create Transaction Controller instances with Include duration of timer and pre-post processors in generated sample set to false. This default value reflect more accurately response time. `__escapeOroRegexpChars` function (which escapes ORO reserved characters) no longer trims the value (see Bug 55328 ) The commons-lang-2.6.jar has been removed from embedded libraries in `jmeter/lib` folder as it is not needed by JMeter at run-time (it is only used by Apache Velocity for generating documentation). If you use any plugin or third-party code that depends on it, you need to add it in `jmeter/lib` folder

For this release we want to give special thanks to the following reporters for the clear reports and tests made after our fixes: Immanuel Hayden (immanuel.hayden at gmail.com) Danny Lade (dlade at web.de) Brent Cromarty (brent.cromarty at yahoo.ca) Wolfgang Heider (wolfgang.heider at racon.at) Shmuel Krakower (shmulikk at gmail.com) Apologies if we have omitted anyone else. # Version 2.9 ## New and Noteworthy ### Core Improvements: #### * A new Extractor that uses CSS or jquery-like selector syntax has been introduced, it allows using either JODD or JSOUP implementations
> Result: the title of the page in a JMeter variable
> #### * JMeter can now handle different types of documents (PDF, MsOffice files, Apache OpenOffice's files, …) within different elements Regular Expression Extractor, extract text from documents Assertion Response, check text in documents View Results Tree, view as a text the documents
> #### * A new Regex User Parameters Pre-Processor that enables injecting input parameter names and values using a reference extracted by Regular Expression Extractor from a previous response
> #### * TCP Sampler: new options TCP Sampler has been enhanced with new options to allow setting Close Connection, SO_LINGER and End of line(EOL) byte value
> #### * A new function __escapeOroRegexpChars(,) has been introduced quote ORO regexp meta characters #### * ForEach Controller: new fields ForEach Controller has now 2 new fields to control start and end of loop
> #### * Result Status Action Handler now has a new option to "Start next thread loop"
> #### * JMS Publisher: new option JMS Publisher can now send Bytes Messages
> #### * Memory and performance improvements Significant improvements have been done in this version on memory usage per Thread and CPU when more than one Post Processor is used as child of a Sampler JSR223 Elements (enable using Groovy, Scala, … as scripting languages) have been improved to enable caching of Compilation results when scripts are passed in Text area
> Some configuration defaults have changed to improve performances by default(see Bug 54412 ), see description in New and Noteworthy section. Distributed testing now uses MODE_STRIPPED_BATCH, which returns samples in batch mode (every 100 samples or every minute by default). Note also that MODE_STRIPPED_BATCH strips response data from SampleResult, so if you need it change to another mode (mode property in jmeter.properties) Result data are now saved to CSV by default (jmeter.save.saveservice.output_format in jmeter.properties) #### * XPath Assertion now enables using a JMeter variable as input
> ### GUI and ergonomy Improvements: #### * Search feature has been improved to search within more internal fields of elements and expand search results #### * Copy/paste is now possible between 2 JMeter instances >= 2.9 version Copy element(s) from one JMeter instance:
> Paste element(s) into a second JMeter instance:
> #### * HTTP Header Manager Allow copy from clipboard to HeaderPanel, headers are supposed to be separated by new line and have the following form name:value
> #### * Module Controller Module Controller has been improved to better render referenced controller and expand it by clicking on a new button
> #### * HTTP Proxy Server HTTP Proxy Server now has a button to add a set of default exclusions for URL patterns, this list can be configured through property : proxy.excludes.suggested
> #### * Rendering of target controller has been improved in HTTP Proxy Server ### HTTP Proxy Server recording: * HTTP Proxy Server now automatically uses HTTP Request with Raw Post Body mode for samples that only have one unnamed argument (JSON, XML, GWT, …) * HTTP Proxy Server does not force user to select the type of Sampler in HTTP Sampler Settings, this allows easier switch between implementations as Sampler do not have this information set anymore
> * SamplerCreator interface has been enriched to meet new requirements for plug-in providers * It is now possible to create binary sampler for x-www-form-urlencoded POST request by modifying proxy.binary.types property to add application/x-www-form-urlencoded * Improved timestamp format auto-detection when reading CSV files ## Known bugs The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see Bug 52496 ). A workaround is to add a sampler at the same level as (or superior to) the If Controller. For example a Test Action sampler with 0 wait time (which doesn't generate a sample), or a Debug Sampler with all fields set to False (to reduce the sample size). Webservice sampler does not consider the HTTP response status to compute the status of a response, thus a response 500 containing a non empty body will be considered as successful, see Bug 54006 . To workaround this issue, ensure you always read the response and add a Response Assertion checking text inside the response. Changing language can break part of the configuration of the following elements (see Bug 53679 ): CSV Data Set Config (sharing mode will be lost) Constant Throughput Timer (Calculate throughput based on will be lost) The numbers that appear to the left of the green box are the number of active threads / total number of threads, these only apply to a locally run test; they do not include any threads started on remote systems when using client-server mode, (see Bug 54152 ). Note that there is a bug in Java on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
>      [java] WARNING: Couldn't flush user prefs:
>      java.util.prefs.BackingStoreException:
>      java.lang.IllegalArgumentException: Not supported: indent-number
> This does not affect JMeter operation. ## Incompatible changes JMeter requires now a Java 6 runtime or higher. Some configuration defaults have changed to improve performances by default (see Bug 54412 ), see description in New and Noteworthy section. Webservice sampler now adds to request the headers that are set through Header Manager, these were previously ignored jdbcsampler.cachesize property has been removed, it previously limited the size of a per connection cache of Map < String, PreparedStatement > , it also limited the size of this map which held the PreparedStatement for SQL queries. This limitation provoked a bug Bug 53995 . It has been removed so now size of these 2 maps is not limited anymore. This change changes behaviour as starting from this version no PreparedStatement will be closed during the test. Starting with this version, there are some important changes on JSR223 Test Elements: JSR223 Test Elements that have an invalid filename (not existing or unreadable) will make test fail instead of making the element silently work In JSR223 Test Elements: responseCodeOk, responseMessageOK and successful are set before script is executed, if responseData is set it will not be overridden anymore by a toString() on script return value View Results Tree now considers response with missing content type as text. In remote Test mode, JMeter now exits in error if one of the remote engines cannot be configured, previously it started the test with available engines. ## Bug fixes ### HTTP Samplers and Proxy Don't log spurious warning messages when using concurrent pool embedded downloads with Cache Manager or CookieManager Bug 54057 - Proxy option to set user and password at startup (-u and -a) not working with HTTPClient 4 Bug 54187 - Request tab does not show headers if request fails Bug 53840 - Proxy Recording : Response message: URLDecoder: Illegal hex characters in escape (%) pattern - For input string: "" " Bug 54351 - HC4 and URI fragments is failing ### Other Samplers Bug 53997 - LDAP Extended Request: Escape ampersand (&), left angle bracket (<) and right angle bracket (>) in search filter tag in XML response data Bug 53995 - AbstractJDBCTestElement shares PreparedStatement between multi-threads Bug 54119 - HTTP 307 response is not redirected Bug 54326 - AjpSampler send file in post throws FileNotFoundException Bug 54331 - AjpSampler throws null pointer on GET request that are protected ### Controllers ### Listeners Bug 54088 - The type video/f4m is text, not binary Bug 54166 - ViewResultsTree could not render the HTML response: handle failure to parse HTML Bug 54287 - Incorrect Timestamp in Response Time Graph when using a date with time in Date format field Bug 54451 - Response Time Graph reports wrong times when the are many samples for same time Bug 54459 - CSVSaveService does not handle date parsing very well ### Timers, Assertions, Config, Pre- & Post-Processors Bug 54058 - In HTTP Request Defaults, the value of field "Embedded URLs must match: is not saved if the check box "Retrieve All Embedded Resources" is not checked.

> ## Known bugs The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see Bug 52496 ). A workaround is to add a sampler at the same level as (or superior to) the If Controller. For example a Test Action sampler with 0 wait time (which doesn't generate a sample), or a Debug Sampler with all fields set to False (to reduce the sample size). Changing language can break part of the configuration of the following elements (see Bug 53679 ): CSV Data Set Config (sharing mode will be lost) Constant Throughput Timer (Calculate throughput based on will be lost) Note that there is a bug in Java on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
>      [java] WARNING: Couldn't flush user prefs:
>      java.util.prefs.BackingStoreException:
>      java.lang.IllegalArgumentException: Not supported: indent-number
> This does not affect JMeter operation. ## Incompatible changes When using CacheManager, JMeter now caches responses for GET queries provided header Cache-Control is different from "no-cache" as described in specification. Furthermore it doesn't put anymore in Cache deprecated entries for "no-cache" responses. See Bug 53521 and Bug 53522 A major change has occurred on JSR223 Test Elements, previously variables set up before script execution where stored in ScriptEngineManager which was created once per execution, now ScriptEngineManager is a singleton shared by all JSR223 elements and only ScriptEngine is created once per execution, variables set up before script execution are now stored in Bindings created on each execution, see Bug 53365 . JSR223 Test Elements using Script file are now Compiled if ScriptEngine supports this feature, see Bug 53520 . Shortcut for Function Helper Dialog is now CTRL+F1 (CMD + F1 for Mac OS), CTRL+F (CMD+F1 for Mac OS) now opens Search Dialog. By default, the TestCompiler now stores details of which pairs it has seen in Controller instances rather than in a static Set. [Bug 53796 ] This gives much better memory behaviour for delayed start test plans, as memory used is proportional to the number of concurrent threads. With the static Set memory usage was proportional to the total thread count. This change is very unlikely to cause a problem. The original behaviour can be restored by setting the property `TestCompiler.useStaticSet=true` HTTPS Spoofing options have been removed from Proxy as HTTPS recording is directly available since JMeter 2.4. ## Bug fixes ### HTTP Samplers and Proxy Bug 53521 - Cache Manager should cache content with Cache-control=private Bug 53522 - Cache Manager should not store at all response with header "no-cache" and store other types of Cache-Control having max-age value Bug 53838 - Pressing "Stop" does not interrupt the TCP sampler Bug 53911 - JmeterKeystore does not allow for key down the list of certificate ### Other Samplers Bug 53348 - JMeter JMS Point-to-Point Request-Response sampler doesn't work when Request-queue and Receive-queue are different Bug 53357 - JMS Point to Point reports too high response times in Request Response Mode Bug 53440 - SSL connection leads to ArrayStoreException on JDK 6 with some KeyManagerFactory SPI Bug 53511 - access log sampler SessionFilter throws NullPointerException - cookie manager not initialized properly Bug 53715 - JMeter does not load WSDL ### Controllers ### Listeners Bug 53742 - When jmeter.save.saveservice.sample_count is set to true, elapsed time read by listener is always equal to 0 Bug 53774 - RequestViewRaw does not show headers unless samplerData is non-null Bug 53802 - IdleTime values are not saved to CSV log Bug 53874 - View Results Tree : If some parameter containing special characters like % is not encoded, RequestViewHTTP fails with java.lang.IllegalArgumentException: URLDecoder: Illegal hex characters in escape (%) pattern and Response is not displayed ### Timers, Assertions, Config, Pre- & Post-Processors Bug 51512 - Cookies aren't inserted into HTTP request with IPv6 Host header ### Functions ### I18N ### General Bug 53365 - JSR223TestElement should cache ScriptEngineManager Bug 53520 - JSR223 Elements : Use Compilable interface to improve performances on File scripts Bug 53501 - Synchronization timer blocks test end.

This should reduce per-thread memory requirements and processing, as only test elements that actually use testIterationStart functionality now need to be handled. Bug 53941 - Add latency to View Result table listener ### Timers, Assertions, Config, Pre- & Post-Processors Bug 53755 - Adding a HttpClient 4 cookie implementation in JMeter.

For example a Test Action sampler with 0 wait time (which doesn't generate a sample), or a Debug Sampler with all fields set to False (to reduce the sample size). ## Incompatible changes When doing replacement of User Defined Variables, Proxy will not substitute partial values anymore when "Regexp matching" is used. It will use Perl 5 word matching ("\b") In User Defined Variables, Test Plan, HTTP Sampler Arguments Table, Java Request Defaults, JMS Sampler and Publisher, LDAP Request Defaults and LDAP Extended Request Defaults, rows with empty Name and Value are no more saved. JMeter now expands the Test Plan tree to the testplan level and no further and selects the root of the tree. Furthermore default value of onload.expandtree is false. Graph Full Results Listener has been removed. When calling "Clear All" command, if Log Viewer is displayed its content will be cleared. ## Bug fixes ### HTTP Samplers and Proxy Bug 52613 - Using Raw Post Body option, text gets encoded Bug 52781 - Content-Disposition header garbled even if browser compatible headers is checked (HC4) Bug 52796 - MonitorHandler fails to clear variables when starting a new parse Bug 52871 - Multiple Certificates not working with HTTP Client 4 Bug 52885 - Proxy : Recording issues with HTTPS, cookies starting with secure are partly truncated Bug 52886 - Proxy : Recording issues with HTTPS when spoofing is on, secure cookies are not always changed Bug 52897 - HTTPSampler : Using PUT method with HTTPClient4 and empty Content Encoding and sending files leads to NullPointerException Bug 53145 - HTTP Sampler - function in path evaluated too early ### Other Samplers Bug 51737 - TCPSampler : Packet gets converted/corrupted Bug 52868 - BSF language list should be sorted Bug 52869 - JSR223 language list currently uses BSF list which is wrong Bug 52932 - JDBC Sampler : Sampler is not marked in error in an Exception which is not of class IOException, SQLException, IOException occurs Bug 52916 - JDBC Exception if there is an empty user defined variable Bug 52937 - Webservice Sampler : Clear Soap Documents Cache at end of Test Bug 53027 - JMeter starts throwing exceptions while using SMTP Sample in a test plan with HTTP Cookie Mngr or HTTP Request Defaults Bug 53072 - JDBC PREPARED SELECT statements should return results in variables like non prepared SELECT ### Controllers Bug 52968 - Option Start Next Loop in Thread Group does not mark parent Transaction Sampler in error when an error occurs Bug 50898 - IncludeController : NullPointerException loading script in non-GUI mode if Includers use same element name ### Listeners Bug 43450 - Listeners/Savers assume SampleResult count is always 1; fixed Generate Summary Results ### Assertions Bug 52848 - NullPointer in "XPath Assertion" ### Functions ### I18N Bug 52551 - Function Helper Dialog does not switch language correctly Bug 52552 - Help reference only works in English ### General Bug 52639 - JSplitPane divider for log panel should be hidden if log is not activated Bug 52672 - Change Controller action deletes all but one child samplers Bug 52694 - Deadlock in GUI related to non AWT Threads updating GUI Bug 52678 - Proxy : When doing replacement of UserDefinedVariables, partial values should not be substituted Bug 52728 - CSV Data Set Config element cannot coexist with BSF Sampler in same Thread Plan Bug 52762 - Problem with multiples certificates: first index not used until indexes are restarted Bug 52741 - TestBeanGUI default values do not work at second time or later Bug 52783 - oro.patterncache.size property never used due to early init Bug 52789 - Proxy with Regexp Matching can fail with NullPointerException in Value Replacement if value is null Bug 52645 - Recording with Proxy leads to OutOfMemory Bug 52679 - User Parameters columns narrow Bug 52843 - Sample headerSize and bodySize not being accumulated for subsamples Bug 52967 - The function __P() couldn't use default value when running with remote server in GUI mode.

Note: the Maven coordinates for the jar were changed from rhino:js to org.mozilla:rhino. This does not affect JMeter directly, but might cause problems if using JMeter in a Maven project with other code that depends on an earlier version of the Rhino Javascript jar. Bug 52675 - Refactor Proxy and HttpRequestHdr to allow Sampler Creation by Proxy Bug 52680 - Mention version in which function was introduced Bug 52788 - HttpRequestHdr : Optimize code to avoid useless work JMeter Ant (ant-jmeter-1.1.1.jar) task was upgraded from 1.0.9 to 1.1.1 Updated to commons-io 2.2 (from 2.1) Bug 53129 - Upgrade XStream from 1.3.1 to 1.4.2 Updated to httpcomponents-client 4.1.3 (from 4.1.2) Updated JMeter distributed testing guide (jmeter_distributed_testing_step_by_step.pdf).

> ### JMS Subscriber sampler With JMS Subscriber, ability to use Selectors
> ### New Logger Panel A new Log Viewer has been added to the GUI and can be enabled from menu Options → Log Viewer:
> This Log Viewer shows the jmeter.log file, and useful (for example) to debug BeanShell/BSF scripts:
> ### The menu item Options / Choose Language is now fully functional The menu item Options / Choose Language now changes all the displayed text to the new language provided all messages are translated. You can help on this by translating into your language. ### Legacy JMX and JTL Avalon format support restored Support for reading/writing the original Avalon XML format of JMX (script) and JTL (sample result) files was dropped in JMeter version 2.4. JMeter can now read the Avalon format files again, however there is no support for saving files in the old format. ### JMeter jars available from Maven repository JMeter jars are now available from Maven repository. ## Known bugs The Include Controller has some problems in non-GUI mode (see Bugs 40671, 41286, 44973, 50898). In particular, it can cause a NullPointerException if there are two include controllers with the same name. The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see Bug 52496 ). A workaround is to add a sampler at the same level as (or superior to) the If Controller. For example a Test Action sampler with 0 wait time (which doesn't generate a sample), or a Debug Sampler with all fields set to False (to reduce the sample size). ## Incompatible changes JMeter versions since 2.1 failed to create a container sample when loading embedded resources. This has been corrected; can still revert to the Bug 51939 behaviour by setting the following property: `httpsampler.separate.container=false` Mirror server now uses default port 8081, was 8080 before 2.5.1. TCP Sampler handles SocketTimeoutException, SocketException and InterruptedIOException differently since 2.6, when these occurs, Sampler is marked as failed. Sample Sender implementations now resolve their configuration on Client side since 2.6. This behaviour can be changed with property sample_sender_client_configured (set it to false). The HTTP User Parameter Modifier test element has been removed; it has been deprecated for a long time. ## Bug fixes ### HTTP Samplers and Proxy Bug 51932 - CacheManager does not handle cache-control header with any attributes after max-age Bug 51918 - GZIP compressed traffic produces errors, when multiple connections allowed Bug 51939 - Should generate new parent sample if necessary when retrieving embedded resources Bug 51942 - Synchronisation issue on CacheManager when Concurrent Download is used Bug 51957 - Concurrent get can hang if a task does not complete Bug 51925 - Calling Stop on Test leaks executor threads when concurrent download of resources is on Bug 51980 - HtmlParserHTMLParser double-counts images used in links Bug 52064 - OutOfMemory Risk in CacheManager Bug 51919 - Random ConcurrentModificationException or NoSuchElementException in CookieManager#removeMatchingCookies when using Concurrent Download Bug 52126 - HttpClient4 does not clear cookies between iterations Bug 52129 - Reported Body Size is wrong when using HTTP Client 4 and Keep Alive connection Bug 52137 - Problems with HTTP Cache Manager Bug 52221 - Nullpointer Exception with use Retrieve Embedded Resource without HTTP Cache Manager Bug 52310 - variable in IPSource failed HTTP request if "Concurrent Pool Size" is enabled Bug 52371 - API Incompatibility - Methods in HTTPSampler2 now require PostMethod instead of HttpMethod[Base].

(fixed docs) Update velocity.jar to 1.7 (from 1.6.2) Update js.jar to 1.7R3 (from 1.6R5) Update commons-codec 1.5 ⇒ 1.6 Update commons-io 2.0.1 ⇒ 2.1 Update commons-jexl 2.0.1 ⇒ 2.1.1 Update jdom 1.1 ⇒ 1.1.2 Update junit 4.9 ⇒ 4.10 Bug 51954 - Generated documents include </br> entries which cause extra blank lines Bug 52075 - JMeterProperty.clone() currently returns Object; it should return JMeterProperty Updated httpcore to 4.1.4 Bug 49753 - Please publish jMeter artifacts on Maven central repository # Version 2.5.1 ## Summary of main changes HttpClient4 sampler now re-uses connections properly (previously it would use one per sample, which could quickly cause resource exhaustion). Various fixes to JMS samplers Functions are no longer spuriously invoked when used with a Configuration element WebService sampler GUI has been re-organized for better design and more user-friendliness. Some improvements on WSDL configuration assistant Better handling of test shutdown. System.exit now only called if there is no other option; even this can be disabled. ## Known bugs The Include Controller has some problems in non-GUI mode. In particular, it can cause a NullPointerException if there are two include controllers with the same name. The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The If Controller may cause an infinite loop if the condition is always false from the first iteration. A workaround is to add a sampler at the same level as (or superior to) the If Controller. For example a Test Action sampler with 0 wait time (which doesn't generate a sample), or a Debug Sampler with all fields set to False (to reduce the sample size). The menu item Options / Choose Language does not change all the displayed text to the new language. [The behaviour has improved, but language change is still not fully working] To override the default local language fully, set the JMeter property "language" before starting JMeter. ## Incompatible changes The HttpClient4 and Commons HttpClient 3.1 samplers previously used a retry count of 3. This has been changed to default to 1, to be compatible with the Java implementation. The retry count can be overridden by setting the relevant JMeter property, for example:
>     httpclient4.retrycount=3
>     httpclient3.retrycount=3
> ## Bug fixes ### HTTP Samplers and Proxy Fix HttpClient 4 sampler so it reuses HttpClient instances and connections where possible. Temporary fix to HC4 sampler to work round HTTPCLIENT-1120. Bug 51863 - Lots of ESTABLISHED connections with HttpClient 4 implementation (vs HttpClient 3.1 impl) Bug 51750 - Retrieve all embedded resources doesn't follow IFRAME Bug 51752 - HTTP Cache is broken when using "Retrieve all embedded resources" with concurrent pool Bug 39219 - HTTP Server: You can't stop it after File→Open Bug 51775 - Port number duplicates in Host header when capturing by HttpClient (3.1 and 4.x) Bug 50617 - Monitor Results legend show "dead" server although values from the server are retrieved ### Other Samplers Bug 50424 - Web Methods drop down list box inconsistent Bug 43293 - Java Request fields not cleared when creating new sampler Bug 51830 - Webservice Soap Request triggers too many popups when Webservice WSDL URL is down WebService(SOAP) request - add a connect timeout to get the wsdl used to populate Web Methods when server doesn't response Bug 51841 - JMS : If an error occurs in ReceiveSubscriber constructor or Publisher, then Connections will stay open Bug 51691 - Authorization does not work for JMS Publisher and JMS Subscriber Bug 51840 - JMS : Cache of InitialContext has some issues Bug 47888 - JUnit Sampler re-uses test object ### Controllers If Controller - Fixed two regressions introduced by Bug 50032 (see Bug 50618 too) If Controller - Catches a StackOverflowError when a condition returns always false (after at least one iteration with return true) See Bug 50618 Bug 51869 - NullPointer Exception when using Include Controller ### Listeners ### Assertions ### Functions Bug 48943 - Functions are invoked additional times when used in combination with a Config Element ### I18N WebService(SOAP) request - add I18N for some labels ### General Bug 51831 - Cannot disable UDP server or change the maximum UDP port Bug 51821 - Add short-cut for Enabling / Disabling (sub)tree or branches in test plan. Bug 47921 - Variables not released for GC after JMeterThread exits. Bug 51839 - "… end of run" printed prematurely Bug 51847 - Some JUnit tests are Locale sensitive and fail if Locale is different from US Bug 51855 - Parent samples may have slightly inaccurate elapsed times Bug 51880 - The shutdown command is not working if I invoke it before all the thread are started Remote Shut host menu item was not being enabled. Bug 51888 - Occasional deadlock when stopping a testplan ## Improvements ### HTTP Samplers Bug 51380 - Control reuse of cached SSL Context from iteration to iteration Bug 51882 - HTTPHC3Client uses a default retry count of 3, make it configurable; default is now 1 Change the default HttpClient 4 sampler retry count to 1 ### Other samplers Beanshell Sampler now supports Interruptible interface Bug 51605 - WebService(SOAP) Request - WebMethod field value changes surreptitiously for all the requests when a value is selected in a request WebService(SOAP) Request - Reorganized GUI for better design and more user-friendliness ### Controllers ### Listeners Bug 42246 - Need for a 'auto-scroll' option in "View Results Tree" and "Assertion Results" View Results Tree: Regexp Tester - little improvements on user interface ### Timers, Assertions, Config, Pre- & Post-Processors Bug 51885 - Allow a JMeter Variable as input to XPathExtractor ### Functions ### I18N ### General Bug 51822 - (part 1) save 1 invocation of GuiPackage#getCurrentGui Added AsynchSampleSender which sends samples from server to client asynchronously. Upgraded to htmlparser 2.1; JavaMail 1.4.4; JUnit 4.9 ## Non-functional changes Bug 49976 - FormCharSetFinder visibility is default instead of public. Bug 50917 - Property CookieManager.save.cookies not honored when set from test plan Improve error logging when Javascript errors are detected. Updated documentation footer # Version 2.5 ## Summary of main changes The HTTP implementation can now be selected at run-time, and JMeter now also supports Apache HttpComponents HttpClient 4.x. Note that Commons HttpClient 3.1 is no longer actively developed, and support may be removed from JMeter in a future release. The HTTP sampler now allows concurrent downloads of embedded resources in an HTML page The HTTP Sampler can now report the size of a request before decompression. The JMS and Mail samplers have been improved. The new Test Fragment Test Element makes using Include Controllers easier There are various improvements to the View Results Tree Listener Bug 30563 - Thread Group should have a start next loop option on Sample Error There are two new Thread Group types - setUp and tearDown - which are run before and after the main Thread groups. Client-Server mode now supports external stop/shutdown via UDP multiple JMeter server instances can be started on the same host without needing to change the port property. Bug 50516 - "Host" header in HTTP Header Manager is not included in generated HTTP request ## Known bugs The Include Controller has some problems in non-GUI mode. In particular, it can cause a NullPointerException if there are two include controllers with the same name. Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The menu item Options / Choose Language does not change all the displayed text to the new language. [The behaviour has improved, but language change is still not fully working] To override the default local language fully, set the JMeter property "language" before starting JMeter. ## Incompatible changes Unsupported methods are no longer converted to GET by the Commons HttpClient sampler. Removed method public static long currentTimeInMs(). This has been replaced by the instance method public long currentTimeInMillis(). ProxyControl.getSamplerTypeName() now returns a String rather than an int. This is internal to the workings of the JMeter Proxy & its GUI, so should not affect any user code. ## Bug fixes ### HTTP Samplers and Proxy Bug 50178 - HeaderManager added as child of Thread Group can create concatenated HeaderManager names and OutOfMemoryException Bug 50392 - value is trimmed when sending the request in Multipart Bug 50686 - HeaderManager logging too verbose when merging instances Bug 50963 - AjpSampler throws java.lang.StringIndexOutOfBoundsException Bug 50516 - "Host" header in HTTP Header Manager is not included in generated HTTP request Bug 50544 - In Apache Common Log the HEAD requests cause problems. Bug 51268 - HTTPS request through an invalid proxy causes NullPointerException and does not show in result tree. Rather than delegating to the JMeter thread handler for "unexpected" failures, ensure all Exceptions generate a sample error. Bug 51275 - Cookie Panel clearGui() sets incorrect default policy in Java 1.6 ### Other Samplers Bug 50173 - JDBCSampler discards ResultSet from a PreparedStatement Ensure JSR223 Sampler has access to the current SampleResult Bug 50977 - Unable to set TCP Sampler for individual samples ### Controllers Bug 50032 - Last_Sample_Ok along with other controllers doesn't work correctly when the threadgroup has multiple loops Bug 50080 - Transaction controller incorrectly creates samples including timer duration Bug 50134 - TransactionController : Reports bad response time when it contains other TransactionControllers ### Listeners Bug 50367 - Clear / Clear all in View results tree does not clear selected element ### Assertions Bug 51488 - Assertion: Variable name scope is shared among all assertions (and Bug 51255 ) ### Functions Bug 50568 - Function __FileToString(): Could not read file when encoding option is blank/empty ### I18N Bug 50811 - Incomplete Spanish translation ### General Bug 49734 - Null pointer exception on stop Threads command (Run → Stop) Bug 49666 - CSV Header read as data after EOF Bug 45703 - Synchronizing Timer Bug 50088 - fix getAvgPageBytes in SamplingStatCalculator so it returns what it should Bug 50203 Cannot set property "jmeter.save.saveservice.default_delimiter=\t" mirror-server.sh - fix classpath to use : separator (not ;) Bug 50286 - URL Re-writing Modifier: extracted jsessionid value is incorrect when is between XML tags System.nanoTime() tends to drift relative to System.currentTimeMillis(). Change SampleResult to recalculate offset each time. Also enable reversion to using System.currentTimeMillis() only. Bug 50425 - Remove thread groups from Controller add menu Bug 50675 - CVS Data Set Config incompatible with Remote Start Fixed RMI startup to provide location of JMX file relative to user.dir. Bug 50221 - Renaming elements in the tree does not resize label Bug 51002 - Stop Thread if CSV file is not available. JMeter now treats IOError as EOF. Define sun.net.http.allowRestrictedHeaders=true by default. This fixes Bug 51238 . Bug 51645 - CSVDataSet does not read UTF-8 files when file.encoding is UTF-8 ## Improvements ### HTTP Samplers AJP Sampler now implements Interruptible Allow HTTP implementation to be selected at run-time Bug 50684 - Optionally disable Content-Type and Transfer-Encoding in Multipart POST Bug 50943 - Allowing concurrent downloads of embedded resources in html page Bug 50170 - Bytes reported by http sampler is after GUnZip Add optional properties to allow change the method to get response size Hiding the proxy password on HTTP Sampler (just on GUI, not in JMX file) ### Other samplers Bug 49622 - Allow sending messages without a subject (SMTP Sampler) Bug 49603 - Allow accepting expired certificates on Mail Reader Sampler Bug 49775 - Allow sending messages without a body Bug 49862 - Improve SMTPSampler Request output.

All BeanShell test elements now have the script variables "prev" and "Label" defined. Bug 50708 - Classpath jar order in NewDriver not alphabetically Bug 50659 - JMeter server does not support concurrent tests - prevent client from starting another Added remote shutdown functionality Client JMeter engine now supports external stop/shutdown via UDP UDP shutdown can now use a range of ports, from jmeterengine.nongui.port=4445 to jmeterengine.nongui.maxport=4455, allowing multiple JMeter instances on the same host without needing to change the port property. Updated to httpcore 4.1.3 and httpclient 4.1.2 ## Non-functional changes Bug 50008 - Allow BatchSampleSender to be subclassed Bug 50450 - use System.array copy in jacobi solver as, being native, is more performant. Bug 50487 - runSerialTest verifies objects that never need persisting Use Thread.setDefaultUncaughtExceptionHandler() instead of private ThreadGroup Update to Commons Net 3.0 # Version 2.4 ## Summary of main changes JMeter now requires at least Java 1.5. HTTP Proxy can now record HTTPS sessions. JUnit sampler now supports JUnit4 annotations. Added JSR223 (javax.script) test elements. MailReader Sampler can now use any protocol supported by the underlying implementation. An SMTP Sampler has been added. JMeter now allows users to provide their own Thread Group implementations. View Results Tree now supports more display options, including search and Regex Testing. StatCalculator performance is much improved; Aggregate Report etc. need far less memory. JMS samplers have been extensively reworked, and should no longer lose messages. Correlation processing is improved. JMS Publisher and Subscriber now support both Topics and Queues. Many other improvements have been made, please see below and in the manual. ## Known bugs The Include Controller has some problems in non-GUI mode. In particular, it can cause a NullPointerException if there are two include controllers with the same name. Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The menu item Options / Choose Language does not change all the displayed text to the new language. [The behaviour has improved, but language change is still not fully working] To override the default local language fully, set the JMeter property "language" before starting JMeter. ## Incompatible changes HTTP Redirect now defaults to "Follow Redirects" rather than "Redirect Automatically". This is to enable JMeter to track cookies that may be sent during redirects. This does not affect existing test plans; it only affects the default for new HTTP Samplers. The Avalon file format for JMX and JTL files is no longer supported. Any such files will need to be converted by reading them in JMeter 2.3.4 and resaving them. The XPath Assertion and XPath Extractor elements no longer fetch external DTDs by default; this can be changed in the GUI. JMSConfigGui has been renamed as JMSSamplerGui. This does not affect existing test plans. The constructor public SampleResult(SampleResult res) has been changed to become a true "copy constructor". It no longer calls addSubResult(). This may possibly affect some 3rd party add-ons. ## Bug fixes ### HTTP Samplers and Proxy Bug 47445 - Using Proxy with https-spoofing secure cookies need to be unsecured Bug 47442 - Missing replacement of https by http for certain conditions using https-spoofing Bug 48451 - Error in: SoapSampler.setPostHeaders(PostMethod post) in the else branch Bug 48542 - SoapSampler uses wrong response header field to decide if response is gzip encoded Bug 48568 - CookieManager broken for AjpSampler Bug 48570 - AjpSampler doesn't support query parameters (GET/POST) Bug 46901 - HTTP Sampler does not process var/func refs correctly in first file parameter Bug 43678 - Handle META tag http-equiv charset?

Added Comparison Assertion Visualizer Bug 47907 - Improvements (enhancements and I18N) Comparison Assertion and Comparison Visualizer Bug 36726 - add search function to Tree View Listener Bug 47869 - Ability to cleanup fields of SampleResult Bug 47952 - Added JSR223 Listener Bug 47474 - View Results Tree support for plugin renderers Allow Idle Time to be saved to sample log files Bug 48259 - Improve StatCalculator performance by using TreeMap Listeners using SamplingStatCalculator have much reduced memory needs as the Sample cache has been moved to the new CachingStatCalculator class. In particular, Aggregate Report can now handle large numbers of samples. Aggregate Report and Summary Report now allow column headers to be optionally excluded Bug 49506 - Add .csv File Extension in open dialog box from "read from file" functionality of listeners Bug 49545 - Formatted (parsed) view of Sample Result in Results Tree ### Timers, Assertions, Config, Pre- & Post-Processors Bug 47338 - XPath Extractor forces retrieval of document DTD Added Comparison Assertion Bug 47952 - Added JSR223 PreProcessor and PostProcessor Added JSR223 Assertion Added BSF Timer and JSR223 Timer Bug 48511 - add parent,child,all selection to regex extractor Add Sampler scope selection to XPathExtractor Regular Expression Extractor, Response Assertion and Size Assertion can now be applied to a JMeter variable Bug 46790 - CSV Data Set Config should be able to parse CSV headers ### Functions Bug 47565 - [Function] FileToString ### I18N Bug 47938 - Adding some French translations for new elements Bug 48714 - add new French messages ### General Bug 47223 - Slow Aggregate Report Performance (StatCalculator) Bug 47980 - hostname resolves to 127.0.0.1 - specifying IP not possible Bug 47943 - DisabledComponentRemover is not used in Start class HeapDumper class for runtime generation of dumps Basic read-only JavaMail provider implementation for reading raw mail files Bug 49540 - Sort "Add" menus alphabetically ## Non-functional changes Beanshell, JavaMail and JMS API (Apache Geronimo) jars are now included in the binary archive. Add TestBean Table Editor support Removed all external libraries from SVN; added download_jars Ant target Updated various jar files: BeanShell - 2.0b4 ⇒ 2.0b5 Commons Codec - 1.3 ⇒ 1.4 Commons-Collections - 3.2 ⇒ 3.2.1 JTidy ⇒ r938 JUnit - 3.8.2 ⇒ 4.8.1 Logkit - 1.2 ⇒ 2.0 Xalan Serializer = 2.7.1 (previously erroneously shown as 2.9.1) Xerces xml-apis = 1.3.04 (previously erroneously shown as 2.9.1) Some jar files were renamed. # Version 2.3.4 ## Summary of main changes This is a minor bug-fix release, mainly to correct some bugs that were accidentally added in 2.3.3. ## Known bugs The Include Controller has some problems in non-GUI mode. In particular, it can cause a NullPointerException if there are two include controllers with the same name. Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The menu item Options / Choose Language does not change all the displayed text to the new language. [The behaviour has improved, but language change is still not fully working] To override the default local language fully, set the JMeter property "language" before starting JMeter. ## Bug fixes ### HTTP Samplers and Proxy Bug 47321 - HTTPSampler2 response timeout not honored ### Other Samplers Bug 47290 - Infinite loop on connection factory lookup (JMS) JDBC Sampler should not close Prepared or Callable statements as these are cached ### Controllers Bug 39509 - Once-only controller running twice ### Listeners Change ResultCollector to only warn if the directory was not created Fix some synchronisation issues in ResultCollector and SampleResult (wrong locks were being used) ### I18N Fixed bug introduced in 2.3.3: JMeter does not start up if there is no messages.properties file for the default Locale. ### General Fix problems with remote clients - bug introduced in 2.3.3 Bug 47377 - Make ClassFinder more robust and close zipfile resources Fix some errors in generating the documentation (latent bug revealed in 2.3.3 when Velocity was upgraded) ## Improvements ### Other samplers Bug 47266 - FTP Request Sampler: allow specifying an FTP port, other than the default # Version 2.3.3 ## Summary of main changes The handling of test closedown is much improved. The gradual "Shutdown" command now waits until all threads have stopped, and does not report an error if threads don't stop within 5 seconds. The immediate "Stop" command can now be used if "Shutdown" takes too long. Also the immediate "Stop" command is able to interrupt samplers which support the new Interruptible interface (e.g. HTTP and SOAP, FTP). This allows immediate completion of pending responses. Non-GUI mode tests can also now be sent a "Shutdown" or "Stop" message. Test Action now supports a "Stop Now" action, as do the Thread Group and Result Status Action Handler Post Processor elements. HTTP Cookie handling is improved, and HTTP POST can now use variable file names correctly. HTTP, SOAP/XML-RPC and WebService(SOAP) sampler character encodings updated to be more consistent. HTTP Samplers now support connection and response timeouts (requires JVM 1.5 for the HTTP Java sampler). Together with the closedown improvements described above, this should avoid most cases where a test run hangs. Multiple Header Manager elements are now supported for a single HTTP sampler. The Proxy Server is improved, and no longer stores "Host" headers by default. JDBC Request can optionally save the results of Select statements to variables. JDBC Request now handles quoted strings and UTF-8, and can handle arbitrary variable types. There are several new functions: __char() function: allows arbitrary Unicode characters to be entered in fields. __unescape() function: allows Java-escaped strings to be used. _unescapeHtml() function: decodes Html-encoded text. __escapeHtml() function: encodes text using Html-encoding. A reference to a missing function - e.g. ${__missing(a)} - is now treated the same as a missing variable. Previously the function name - and leading { - were dropped. This makes it easier to debug test plans. Some Assertions can now be applied to sub-samples as well as (or instead of) just the parent sample. There is a new Random Variable Configuration element. JMS samplers are much improved (see details below). The TCP Sampler now supports some additional clients and is a bit more flexible. Client-server mode has been improved, and the server can optionally use a fixed RMI port, which should help with setting up firewalls. Various I18N changes have been made; language change works better (though not perfect yet). There are improved French translations as well as new Polish and Brazilian Portuguese translations. The BeanShell jar is now included with the binary archive; there is no need to download it separately. ## Known bugs The Include Controller has some problems in non-GUI mode. In particular, it can cause a `NullPointerException` if there are two include controllers with the same name. Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The menu item Options → Choose Language does not change all the displayed text to the new language. [The behaviour has improved, but language change is still not fully working] To override the default local language fully, set the JMeter property "`language`" before starting JMeter. ## Incompatible changes When loading sample results from a file, previous results are no longer cleared. This allows one to merge multiple files. If the previous behaviour is required, use the menu item Run → Clear (Ctrl + Shift + E) or Run → Clear All (Ctrl + E) before loading the file. The test elements "Save Results to a file" and "Generate Summary Results" are now shown as Listeners. They were previously shown as Post-Processors, even though they are implemented as Listeners. The Cookie Manager no longer saves incoming cookies as variables by default. To save cookies as variables, define the property "`CookieManager.save.cookies=true`". Also, cookies names are prefixed with "`COOKIE_`" before they are stored (this avoids accidental corruption of local variables) To revert to the original behaviour, define the property "`CookieManager.name.prefix=` " (one or more spaces). The Counter element is now shown as a Configuration element. It was previously shown as a Pre-Processor, even though it is implemented as a Config item. The above changes only affect the icons that are displayed and the locations in the GUI pop-up menus. They do not affect test plans or test behaviour. The PreProcessors are now invoked directly by the JMeterThread class, rather than by the TestCompiler#configureSampler() method. (JMeterThread handles the PostProcessors). This does not affect test plans or behaviour, but could perhaps affect 3rd party add-ons (very unlikely). Moved the Scoping Rules sub-section from Section 3. "Building a Test Plan" to Section 4. "Elements of a test plan" The While controller now trims leading and trailing spaces from the condition value before it is compared with `LAST`, blank or false. The "threadName" variable in the _jexl() and __javaScript() functions was previously misspelt as "theadName". The following deprecated methods were removed from JOrphanUtils: booleanToString(boolean) and valueOf(boolean). Java 1.4+ has these methods in the Boolean class. The TestElement interface has some new methods: void setProperty(String key, String value, String dflt) void setProperty(String key, boolean value, boolean dflt) void setProperty(String key, int value) void setProperty(String key, int value, int dflt) int getPropertyAsInt(String key, int defaultValue) These are implemented in the AbstractTestElement class which all elements should extend so this is unlikely to cause a problem. ## Bug fixes ### HTTP Samplers and Proxy Bug 46332 - HTTP Cookie Manager ignores manually defined cookies (bug introduced in r707810) Cookie Manager was not passing cookie policy to runtime threads so they always used compatibility mode Add version attribute to JMeter Cookie class (needed for proper cookie support) Cookie Manager now saves/restores cookie versions Check validity of cookies before storing them. HTTPSamplers can now use variables in POSTed file names Fix processing of first file name in HTTP POST so functions/variables work (bug introduced with multiple file support) Bug 45831 - WS Sampler reports incorrect throughput if SOAP packet creation fails HTTP, SOAP/XML-RPC and WebService(SOAP) sampler character encodings updated to be more consistent Bug 46148 - HTTP sampler fails on SSL requests when logging for jmeter.util is set to DEBUG Fix Java 1.6 https error: java.net.SocketException: Unconnected sockets not implemented Bug 46838 - if there was no data, still need to set latency in HTTPSampler Bug 46993 - Saving from Header Manager generates ClassCastException Bug 46690 - handling of 302 redirects with invalid relative paths. JMeter now removes extraneous leading "../" segments (as do many browsers) Bug 44521 - empty variables for a POST in the HTTP Request don't get ignored Bug 46977 - JMeter does not handle HTTP headers not delimited by whitespace Fix bug in HTTP file: handling - read bytes, not characters in the default encoding. Remove Host from headers saved by the Proxy server, as that will normally be generated by the HTTP stack Bug 45199 - don't try to replace blank variables in Proxy recording Change HTTPS spoofing so https: links are replaced even when URL match fails Bug 46436 - Improve error reporting in Proxy Gui Bug 46435 - More verbose error msg for error 501 (Proxy Server) ### Other Samplers The "prev" and "sampler" objects are now defined for BSF test elements Fix NPE (in DataSourceElement) when using JDBC in client-server mode Bug 45425 - JDBC Request does not support Unicode (changed sampler to use UTF-8) Bug 46522 - Incorrect "Response data" in JDBC sample when column names are missing Bug 46821 - JDBC select request doesn't store the first column in the variables Bug 43791 - ensure QueueReceiver is closed in JMS Point to Point sampler Bug 46016 - avoid possible NPE in JMSSampler Bug 46142 - JMS Receiver now uses MessageID Bug 45458 - Point to Point JMS in combination with authentication Bug 45460 - JMS TestPlan elements depend on resource property Various ReceiveSubscriber thread-safety fixes JMSPublisher and Subscriber fixes: thread-safety, support dynamic locale changes, locale independence for JMX attribute values FTP Sampler now logs out before disconnecting. TCP sampler now calls setupTest() and teardownTest() methods Bug 45887 - TCPSampler: timeout property incorrectly set ### Controllers Fix NPE when using nested Transaction Controllers with parent samples Fix processing of Transaction Controller parent mode so current sampler is set to actual sampler Bug 44941 - Throughput controllers should not share global counters Bug 47120 - Throughput Controller: change percent executions to total executions, the value is stored in a String and interpreted as 1 execution Bug 47150 - ThreadGroup with a loop count of zero causes infinite loop Bug 47009 - Insert parent caused child controller name to be reset Bug 47165 - Using duplicate Module Controller names in command line mode causes NPE ### Listeners Mailer Visualizer documentation now agrees with code i.e. failure/success counts need to be exceeded to trigger the mail. Mailer Visualizer now shows the failure count Mailer Visualiser - fix parsing of multiple e-mail address when using Test button Bug 45976 - incomplete result file when using remote testing with more than 1 server Fix Summariser so it works in client server mode Bug 34096 - Duplicate samples not eliminated when writing to CSV files Save "Include group Name in Label" setting in Aggregate and Summary reports The JMeter variable "sample_variables" is sent to all server instances to ensure the data is available to the client. CSVSaveService - check for EOF while reading quoted string ### Assertions Bug 45749 - Response Assertion does not work with a substring that happens to be an invalid RE Bug 45904 - Allow 'Not' Response Assertion to succeed with null sample ### Functions Fix regex function - was failing to process $m$mid$n$ correctly Protect against possible NPE in RegexFunction if called during test shutdown. Avoid NPE if XPath function does not match any nodes Correct the variable name "theadName" to "threadName" in the __jexl() and __javaScript() functions A reference to a missing function - e.g. ${__missing(a)} - is now treated the same as a missing variable. Previously the function name - and leading { - were dropped. ### I18N Fixed language change handling for menus (does not yet work for TestBeans) Add HeaderAsPropertyRenderer to support header resource names; use this to fix locale changes in various GUI elements Bug 46424 - corrections to French translation Bug 46844 - "Library" label in test plan are not I18N Bug 47064 - fixes for Mac LAF Bug 47127 - Unable to change language to pl_PL Bug 47137 - Labels in View Results Tree aren't I18N Bug 46423 - I18N of Proxy Recorder Bug 45928 - AJP/1.3 Sampler doesn't retrieve its label from messages.properties ### General Prompt to overwrite an existing file when first saving a new test plan Amend TestBeans to show the correct popup menu for Listeners Bug 45185 - CSV dataset blank delimiter causes OOM Fix incorrect GUI classifications: "Save Results to a file" and "Generate Summary Results" are now shown as Listeners. "Counter" is now shown as a Configuration element. Bug 41608 - misleading warning log message removed Bug 46359 - BSF JavaScript Preprocessor cannot access sampler variable on first iteration (Implement temporary work-round for BSF-22) Bug 46407 - BSF elements do not load script files, attempt to interpret filename as script Better handling of Exceptions during test shutdown Fix potential thread safety issue in JMeterThread class Bug 46491 - Incorrect value for the last variable in "CSV Data Set Config" (error in processing quoted strings) ## Improvements ### HTTP Samplers Bug 45479 - Support for multiple HTTP Header Manager nodes HTTP Samplers now support connection and request timeouts (requires Java 1.5 for Java Http sampler) Apache SOAP 2.3.1 does not give access to HTTP response code/message, so WebService sampler now treats an empty response as an error Mirror server now supports "X-Sleep" header - if this is set, the responding thread will wait for the specified number of milliseconds Bug 45694 - Support GZIP compressed logs in Access Log Sampler ### Other samplers JDBC Request can optionally save the results of Select statements to variables. JDBC Request now handles quoted strings. JDBC Request now handles arbitrary variable types. LDAP result data now formatted with line breaks Bug 45200 - MailReaderSampler: store the whole MIME message in the SamplerResult Bug 45571 - JMS Sampler correlation enhancement Bug 46030 - Extend TCP Sampler to Support Length-Prefixed Binary Data Add classname field to TCP Sampler GUIs ### Controllers Allow If Controller to use variable expressions (not just Javascript) Trim spaces from While Controller condition before comparing against LAST, blank or false ### Listeners Save Responses to a file can save the generated filename(s) to variables. Add option to skip suffix generation in Save Responses to a File Bug 43119 - Save Responses to file: optionally omit the file number Add BSF Listener element Bug 47176 - Monitor Results : improve load status graphic Bug 40045 - Allow Results monitor to select a specific connector Read XML JTL files more efficiently - pass samples to visualizers as they are read, rather than saving them all and then processing them ### Assertions, Config, Pre- & Post-Processors Bug 45903 - allow Assertions to apply to sub-samples Add Body (unescaped) source option to Regular Expression Extractor. Random Variable - new configuration element to create random numeric variables ### Functions Add OUT and log variables to __jexl() function Use Script to evaluate __jexl() function so can have multiple statements. Add log variable to the __javaScript() function Added __char() function: allows arbitrary Unicode characters to be entered in fields. Added __unescape() function: allows Java-escaped strings to be used. Added __unescapeHtml() function: decodes Html-encoded text. Added __escapeHtml() function: encodes text using Html-encoding. ### I18N Bug 45929 - improved French translations Bug 47132 - Brazilian Portuguese translations Bug 46900 - Polish translations Added locales.add property to allow for new Locales ### General Allow spaces in JMeter path names (apply work-round for Java Bug 4496398) Process JVM_ARGS last in script files so users can override default settings Bug 46636 - Allow server mode to optionally use a fixed rmi port Make some samplers interruptible: HTTP (both), SoapSampler, FTPSampler Test Action now supports "Stop Now" action, as do the Thread Group and Result Status Post Processor elements The Menu items Stop and Shutdown now behave better. Shutdown will now wait until all threads exit. In GUI mode it can be cancelled and Stop run instead. Stop now reports if some threads will not exit, and exits if running in non-GUI mode Add UDP server to wait for shutdown message if running in non-GUI mode; add UDP client to send the message. Bug 41209 - JLabeled* and ToolTips Include BeanShell 2.0b4 jar in binary download. ## Non-functional changes Introduce AbstractListenerGui class to make it easier to create Listeners with no visual output Assertions are run after PostProcessors; change order of pop-up menus accordingly Remove unnecessary clone() methods from function classes Moved PreProcessor invocation to JMeterThread class Made HashTree Map field final Improve performance of calling ResultCollector#isSampleWanted() for multiple samples Updated to new versions of: xmlgraphics-commons (1.3.1), jdom (1.1), xstream (1.3.1), velocity (1.6.2) ## Version 2.3.2 ### Summary of main changes #### Bug fixes Version 2.3.1 changed the way binary and text content types were determined as far as the View Results Tree Listener was concerned: originally everything except "image/" content types were considered text, but 2.3.1 introduced a check for specific content types. This has caused problems, as several popular types were omitted and these were no longer shown by default in the Response tab. Rather than try to list all the possible text types, JMeter now just checks for the following binary types: image/* audio/* video/* All other types are now assumed to be text. JMeter 2.3.1 introduced a bug in the Cookie Manager - if "Clear Cookie each iteration" was selected, all threads would see the same cookies. This bug has been corrected. #### Improvements The Proxy server can now record binary requests. By default the content types application/x-amf and application/x-java-serialized-object will be treated as binary and saved in a file. To change the content types, update the property proxy.binary.types. The CSV Dataset configuration element has new file sharing options: per thread group, per thread, per identifier. This allows for more flexible file processing, e.g. each thread can process the same data in the same order. Switch Controller now works properly with functions and variables, and the condition can now be a name instead of a number. Simple Controller now works properly under a While Controller CSV fields in JTL files can now contain delimiters. CSV and XML files can now contain additional variables (define the JMeter property sample_variables). Response Assertion can now match on substrings (i.e. not regular expression). Regex extractor can operate on variables. XPath processing is improved; Tidy errors are handled better. Save Table Data buttons added to Summary and Aggregate reports to allow easy saving of the calculated data. HTTP samplers can now save just the MD5 hash of responses, rather than the entire response. As a special case, if the HTTP Sampler path starts with "http://" or "https://" then this is used as the full URL, overriding the host and port fields. The HTTP Samplers can now POST multiple files. Webservice(SOAP) Sampler can now load local WSDL files using the "file:" protocol. A simple HTTP Cache Manager has been added. This needs further development. View Results Tree Listener now uses Tidy to display XML. This should allow more content to be displayed successfully. It also avoids the need to download remote DTD files, which can slow the rendering considerably. MailReader sampler now supports POP3S and IMAPS protocols. Individual mails are now added as sub-samples. Various improvements to the BSF Sampler: now supports Jexl, and Javascript bug works properly. Added BSF PreProcessor, PostProcessor and Assertion test elements. All now have access to "props" JMeter Properties object. Number of classes loaded in non-GUI mode is much reduced. ### Known bugs The Include Controller has some problems in non-GUI mode. In particular, it can cause a NullPointerException if there are two include controllers with the same name. Once Only controller behaves OK under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified). The menu item Options / Choose Language does not change all the displayed text to the new language. To override the default local language, set the JMeter property "language" before starting JMeter. ### Incompatible changes To reduce the number of classes loaded in non-GUI mode, Functions will only be found if their classname contains the string '.functions.' and does not contain the string '.gui.'. All existing JMeter functions conform to this restriction. To revert to earlier behaviour, comment or change the properties classfinder.functions.* in jmeter.properties. The reference value parameter for intSum() is now optional. As a consequence, if a variable name is used, it must not be a valid integer. The supplied TCPClient implementation no longer treats tcp.eolByte=0 as special. To skip EOL checking, set tcp.eolByte=1000 (or some other value which is not a valid byte) Leading and trailing spaces are trimmed from variable names in function calls. For example, ${__Random(1,63, LOTTERY )} will use the variable 'LOTTERY' rather than ' LOTTERY '. Synchronization has been removed from the RunningSample class (it was not fully threadsafe anyway). Developers of 3rd party add-ons that use the class may need to synchronize access. ### Bug fixes Check that the CSV delimiter is reasonable. Fix Switch Controller to work properly with functions and variables Bug 44011 - application/soap+xml not treated as a text type Bug 43427 - Simple Controller is only partly executed in While loop Bug 33954 - Stack Overflow in If/While controllers (may have been fixed previously) Bug 44022 - Memory Leak when closing test plan Bug 44042 - Regression in Cookie Manager (Bug introduced in 2.3.1) Bug 41028 - JMeter server doesn't alert the user when the host is defined as a loopback address Bug 44142 - Function __machineName causes NPE if parameters are omitted. Bug 44144 - JMS point-to-point: request response test does not work Bug 44314 - Not possible to add more than one SyncTimer Capture Tidy console error output and log it Fix problems using Tidy(tolerant parser) in XPath Assertion and XPath Extractor Bug 44374 - improve timer calculation Regular Expression Extractor now deletes all stale variables from previous matches. Bug 44707 - Running remote test changes internal test plan Bug 44625 - Cannot have two or more FTP samplers with different "put" and "get" actions Bug 40850 - BeanShell memory leak Ensure ResponseCode and ResponseMessage are set for successful JDBC samples FTPSampler now detects and reports failure to open the remote file Class directories defined in search_paths and user.classpath no longer need trailing "/" Bug 44852 SOAP/ XML-RPC Request does not show Request details in View Results Tree WebService(SOAP) Sampler ResponseData now includes the EOLs sent by server Bug 44910 - close previous socket (if any) in TCP Sampler Bug 44912 - Filter not working in Log Parser The BeanShell and BSF component documentation made some incorrect references to the "SampleResponse" object; this has been corrected to "SampleResult" BSF Sampler now works properly with Javascript Test Action "Stop Test" now works Bug 42833 - Argument class uses LinkedHashMap in getArgumentsAsMap() to preserve ordering Bug 45093 - SizeAssertion did not call getBytes() Bug 45007 - Rewrite Location headers when using Proxy HTTPS spoofing Use CRLF rather than LF in Proxy when returning headers to the client Bug 45007 - fix content length header if content may have been changed ### Improvements CSV files can now handle fields with embedded delimiters. longSum() function added Bug 43382 - configure Tidy output (warnings, errors) for XPath Assertion and Post-Processor Bug 43984 - trim spaces from port field Add optional comment to __log() function Make Random function variable name optional Reduce class loading in non-GUI mode by only looking for Functions in class names that contain '.functions.' and don't contain '.gui.' Bug 43379 - Switch Controller now supports selection by name as well as number Can specify list of variable names to be written to JTL files (CSV and XML format) Now checks that the remoteStart options -r and -R are only used with non_GUI -n option Bug 44184 - Allow header to be saved with Aggregate Graph data Added "Save Table Data" buttons to Aggregate and Summary Reports - save table as CSV format with header Allow most functions to be used on the Test Plan. Note __evalVar(), __split() and __regex() cannot be used on the Test Plan. Allow Global properties to be loaded from a file, e.g. -Gglobal.properties Add "Substring" option to Response Assertion Bug 44378 - Turkish localisation Add optional output variable name to Jexl function Add application/vnd.wap.xhtml+xml as a text type Add means to override maximum display size in View Results Tree - set the property: view.results.tree.max_size Use Tidy to display XML in View Results Tree Listener (avoids fetching DTDs) Bug 44487 - German translation As a special case, if the HTTP Sampler path starts with "http://" or "https://" then this is used as the full URL. Bug 44575 - Result Saver can now save only successful results Bug 44650 - CSV Dataset now handles quoted column values Bug 44600 - 1-ms resolution timer when running with Java 1.5+ Bug 44632 - Text input enhancement to FTP Sampler Bug 42204 - add thread group name to Aggregate and Summary reports FTP Sampler sets latency = time to login FTP Sampler sets a URL if it can Bug 41921 - add option for samplers to store MD5 of response; done for HTTP Samplers. Regex Function can now also be applied to a variable rather than just the previous sample result. Remove HTML Parameter Mask,HTTP User Parameter Modifier from menus as they are deprecated Bug 44807 - allow session ids to be terminated by backslash Bug 44784 - allow for broken server returning additional charset Added TESTSTART.MS property / variable = test start time in milliseconds Add POP3S and IMAPS protocols to Mail Reader Sampler. Mail Reader Sampler now creates a sub-sample for each mail. The supplied TCPClient implementation no longer treats tcp.eolByte=0 as special. To skip EOL checking, set tcp.eolByte=1000 (or some other value which is not a valid byte) JUnit sampler GUI now also finds Test classes defined in user.classpath Leading and trailing spaces are trimmed from variable names in function calls. For example, ${__Random(1,63, LOTTERY )} will use the variable 'LOTTERY' rather than ' LOTTERY ' Webservice(SOAP) Sampler can now load local WSDL files using the file: protocol Bug 44872 - Add "All Files" filter to Open File dialogs Mirror server can now be run independently (mirror-server.cmd and mirror-server.sh) Bug 19128 - Added multiple file POST support to HTTP Samplers Allow use of special name LAST to mean the last test run; applies to -t, -l, -j flags Bug 44418 /42178 - CSV Dataset file handling improvements Give BeanShell, Javascript and Jexl functions access to JMeter properties via the "props" object Give BSF Sampler access to JMeter Properties via "props" object Add Jexl as a supported BSF Sampler language Give Beanshell test elements access to JMeter Properties via "props" object Added BSF PreProcessor, PostProcessor and Assertion test elements All BSF elements now have access to System.out via the variable "OUT" Summariser updated to handle variable names Synchronisation added to Summary and Aggregate Report to try to prevent occasional lost samples Bug 44808 ,Bug 39641 - Proxy support for binary requests Bug 28502 - HTTP Resource Cache ### Non-functional changes Better handling of MirrorServer startup problems and improved unit test. Build process now detects missing 3rd party libraries and reports need for both binary and source archives Skip BeanShell tests if jar is not present Update to Xerces 2.9.1, Xalan 2.7.1, Commons IO 1.4, Commons Lang 2.4, Commons-Logging 1.1.1, XStream 1.3, XPP3 1.1.4c Use properties for log/logn function descriptions Check that all jmx files in the demos directory can be loaded OK Update copyright to 2008; use copy tag instead of numeric character in HTML output Methods called from constructors must not be overridable: make GUI init methods private Make static variables final if possible Split changes into current and previous ### Version 2.3.1 #### Summary of changes ##### JMeter Proxy The Proxy spoof function was broken in 2.3; it has been fixed. Spoof now supports an optional parameter to limit spoofing to particular URLs. This is useful for HTTPS pages that have insecure content - e.g. images/stylesheets may be accessed using HTTP. Spoofed responses now drop the default port (443) from https links to make them work better. Ignored proxy samples are now visible in Listeners - the label is enclosed in [ and ] as an indication. Proxy documentation has been improved. ##### GUI changes The Add menus show element types in the order in which they are processed - see Test Plan Execution Order. It is no longer possible to add test elements to inappropriate parts of the tree - e.g. samplers cannot be added directly under a test plan. This also applies to Paste and drag and drop. The File menu now supports a "Revert" option, which reloads the current file. Also the last few file names used are remembered for easy reloading. The Options Menu now supports Collapse All and Expand All items to collapse and expand the test tree. ##### Remote testing The JMeter server now starts the RMI server directly (by default). This simplifies testing, and means that the RMI server will be stopped when the server stops. Functions can now be used in Listener filenames (variables do not work). Command-line option -G can now be used to define properties for remote servers. Option -X can be used to stop a remote server after a non-GUI run. Server can be set to automatically exit after a single test (set property server.exitaftertest=true). ##### Other enhancements JMeter startup no longer loads as many classes; this should reduce memory requirements. Parameter and file support added to all BeanShell elements. Javascript function now supports access to JMeter objects; Jexl function always did have access, but the documentation has now been included. New functions __eval() and __evalVar() for evaluating variables. CSV files with the correct header column names are now automatically recognised when loaded. There is no need to configure the properties. The hostname can now be saved in CSV and XML output files. New "Successes only" option added when saving result files. Errors / Successes only option is now supported when loading XML and CSV files. General documentation improvements. ##### HTTP PUT and DELETE should now work properly. Cookie Manager no longer clears manually entered cookies. Now handles the META tag http-equiv charset ##### JDBC JDBC Sampler now allows INOUT and OUT parameters for Called procedures. JDBC Sampler now allows per-thread connections - set Max Connections = 0 in JDBC Config. #### Incompatible changes JMeter server now creates the RMI registry by default. If the RMI registry has already been started externally, this will generate a warning message, but the server will continue. This should not affect JMeter testing. However, if you are also using the RMI registry for other applications there may be problems. For example, when the JMeter server shuts down it will stop the RMI registry. Also user-written command files may need to be adjusted (the ones supplied with JMeter have been updated). To revert to the earlier behaviour, define the JMeter property: server.rmi.create=false. The Proxy server removes If-Modified-Since and If-None-Match headers from generated Header Managers. To revert to the previous behaviour, define the property proxy.headers.remove with no value #### Bug fixes Bug 43430 - Count of active threads is incorrect for remote samples Throughput Controller was not working for "all thread" counts If a POST body is built from parameter values only, these are now encoded if the checkbox is set. Bug 43584 - Assertion Failure Message contains a comma that is also used as the delimiter for CSV files HTTP Mirror Server now always returns the exact same content, it used to return incorrect data if UTF-8 encoding was used for HTTP POST body, for example Bug 43612 - HTTP PUT does not honor request parameters Bug 43694 - ForEach Controller (empty collection processing error) Bug 42012 - Variable Listener filenames do not get processed in remote tests. Filenames can now include function references; variable references do not work. Ensure Listener nodes get own save configuration when copy-pasted Correct Proxy Server include and exclude matching description - port and query are included, contrary to previously documented. Aggregate Graph and Aggregate Report Column Header is KB/Sec; fixed the values to be KB rather than bytes Fix SamplingStatCalculator so it no longer adds elapsed time to endTime, as this is handled by SampleResult. This corrects discrepancies between Summary Report and Aggregate Report throughput calculation. Default HTTPSampleResult to ISO-8859-1 encoding Fix default encoding for blank encoding Fix Https spoofing (port problem) which was broken in 2.3 Fix HTTP (Java) sampler so http.java.sampler.retries means retries, i.e. does not include initial try Fix SampleResult dataType checking to better detect TEXT documents #### Improvements Add run_gui Ant target, to package and then start the JMeter GUI from Ant Add File→Revert to easily drop the current changes and reload the project file currently loaded Bug 31366 - Remember recently opened file(s) Bug 43351 - Add support for Parameters and script file to all BeanShell test elements SaveService no longer needs to instantiate classes New functions: __eval() and __evalVar() Menu items now appear in execution order Test Plan items can now only be dropped/pasted/merged into parts of the tree where they are allowed Property Display to show the value of System and JMeter properties and allow them to be changed Bug 43451 - Allow Regex Extractor to operate on Response Code/Message JDBC Sampler now allows INOUT and OUT parameters for Called procedures JDBC Sampler now allows per-thread connections Cookie Manager not longer clears cookies defined in the GUI HTTP Parameters without names are ignored (except for POST requests with no file) "Save Selection As" added to main menu; now checks only item is selected Test Plan now has Paste menu item (paste was already supported via ^V) If the default delimiter does not work when loading a CSV file, guess the delimiter by analysing the header line. Add optional "loopback" protocol for HttpClient sampler HTTP Mirror Server now supports blocking waiting for more data to appear, if content-length header is present in request HTTP Mirror Server GUI now has the Start and Stop buttons in a more visible place Server mode now creates the RMI registry; to disable set the JMeter property server.rmi.create=false HTTP Sampler now supports using MIME Type field to specify content-type request header when body is constructed from parameter values Enable exit after a single server test - define JMeter property server.exitaftertest=true Added -G option to set properties in remote servers Added -X option to stop remote servers after non-GUI run Bug 43485 - Ability to specify keep-alive on SOAP/XML-RPC request Bug 43678 - Handle META tag http-equiv charset Bug 42555 - [I18N] Proposed corrections for the french translation Bug 43727 - Test Action does not support variables or functions The Proxy server removes If-Modified-Since and If-None-Match headers from generated Header Managers by default. To change the list of removed headers, define the property proxy.headers.remove as a comma-separated list of headers to remove The javaScript function now has access to JMeter variables and context etc. See JavaScript function Use drop-down list for BSF Sampler language field Add hostname to items that can be saved in CSV and XML output files. Errors only flag is now supported when loading XML and CSV files Ensure ResultCollector uses SaveService encoding Proxy now rejects attempts to use it with https Proxy spoofing can now use RE matching to determine which urls to spoof (useful if images are not https) Proxy spoofing now drops the default HTTPS port (443) when converting https: links to http: Add Successes Only logging and display The JMeter log file name is formatted as a SimpleDateFormat (applied to the current date) if it contains paired single-quotes, .e.g. 'jmeter_'yyyyMMddHHmmss'.log' Added Collapse All and Expand All Option menu items Allow optional definition of extra content-types that are viewable as text #### Non-functional Improvements Functor code tightened up; Functor can now be used with interfaces, as well as pre-defined targets and parameters. Save graphics function now prompts before overwriting an existing file Debug Sampler and Debug PostProcessor added. Fixed up method names in Calculator and SamplingStatCalculator Tidied up Listener documentation. ### Version 2.3 ### Fixes since 2.3RC4 #### Bug fixes Fix NPE in SampleResultConverter - XStream PrettyPrintWriter cannot handle nulls If Java HTTP sampler sees null ResponseMessage, replace with HTTP header Bug 43332 - 2.3RC4 does not clear Guis based on TestBean Bug 42948 - Problems with Proxy gui table fields in Java 1.6 Fixup broken jmeter-server script Bug 43364 - option to revert If Controller to pre 2.3RC3 behaviour Bug 43449 - Statistical Remote mode does not handle Latency Bug 43450 (partial fix) - Allow SampleCount and ErrorCount to be saved to/restored from files #### Improvements Add nameSpace option to XPath extractor Add NULL parameter option to JDBC sampler Add documentation links for Rhino and BeanShell to functions; clarify variables and properties Ensure uncaught exceptions are logged Look for user.properties and system.properties in JMeter bin directory if not found locally #### Fixes since 2.3RC3 Fixed NPE in Summariser (bug introduced in 2.3RC3) Fixed setup of proxy port (bug introduced in 2.3RC3) Fixed errors when running non-GUI on a headless host (bug introduced in 2.3RC3) Bug 43054 - SSLManager causes stress tests to saturate and crash (bug introduced in 2.3RC3) Clarified HTTP Request Defaults usage of the port field Bug 43006 - NPE if icon.properties file not found Bug 42918 - Size Assertion now treats an empty response as having zero length Bug 43007 - Test ends before all threadgroups started Fix possible NPE in HTTPSampler2 if 302 does not have Location header. Bug 42919 - Failure Message blank in CSV output [now records first non-blank message] Add link to Extending JMeter PDF Allow for quoted charset in Content-Type parsing Bug 39792 - ClientJMeter synchronisation needed Bug 43122 - GUI changes not always picked up when short-cut keys used (bug introduced in 2.3RC3) Bug 42947 - TestBeanGUI changes not picked up when short-cut keys used Added serializer.jar (needed for update to xalan 2.7.0) Bug 38687 - Module controller does not work in non-GUI mode #### Improvements since 2.3RC3 Add stop thread option to CSV Dataset Updated commons-httpclient to 3.1 Bug 28715 - allow variable cookie values (set CookieManager.allow_variable_cookies=false to disable) Bug 40873 - add JMS point-to-point non-persistent delivery option Bug 43283 - Save action adds .jmx if not present; checks for existing file on Save As Control + A key does not work for Save All As; changed to Control + Shift + S Bug 40991 - Allow Assertions to check Headers ### Version 2.3RC3 #### Known problems/restrictions: The JMeter remote server does not support multiple concurrent tests - each remote test should be run in a separate server. Otherwise tests may fail with random Exceptions, e.g. ConcurrentModification Exception in StandardJMeterEngine. See Bug 43168 . The default HTTP Request (not HTTPClient) sampler may not work for HTTPS connections via a proxy. This appears to be due to a Java bug, see Bug 39337 . To avoid the problem, try a more recent version of Java, or switch to the HTTPClient version of the HTTP Request sampler. Transaction Controller parent mode does not support nested Transaction Controllers. Doing so may cause a Null Pointer Exception in TestCompiler. Thread active counts are always zero in CSV and XML files when running remote tests. The property file_format.testlog=2.1 is treated the same as 2.2. However JMeter does honour the 3 testplan versions. Bug 22510 - JMeter always uses the first entry in the keystore. Remote mode does not work if JMeter is installed in a directory where the path name contains spaces. BeanShell test elements leak memory. This can be reduced by using a file instead of including the script in the test element. Variables and functions do not work in Listeners in client-server (remote) mode so they cannot be used to name log files in client-server mode. CSV Dataset variables are defined after configuration processing is completed, so they cannot be used for other configuration items such as JDBC Config. (see Bug 40394 ) #### Summary of changes (for more details, see below) Some of the main enhancements are: Htmlparser 2.0 now used for parsing HTTP Authorization now supports domain and realm HttpClient options can be specified via httpclient.parameters file HttpClient now behaves the same as Java Http for SSL certificates HTTP Mirror Server to allow local testing of HTTP samplers HTTP Proxy supports XML-RPC recording, and other proxy improvements __V() function allows support of nested variable references LDAP Ext sampler optionally parses result sets and supports secure mode FTP Sampler supports Ascii/Binary mode and upload Transaction Controller now optionally generates a Sample with subresults HTTPS session contexts are now per-thread, rather than shared. This gives better emulation of multiple users BeanShell elements now support ThreadListener and TestListener interfaces Coloured icons in Tree View Listener and elsewhere to better differentiate failed samples. The main bug fixes are: HTTPS (SSL) handling now much improved Various Remote mode bugs fixed Control + C and Control + V now work in the test tree Latency and Encoding now available in CSV log output Test elements no longer default to previous contents; test elements no longer cleared when changing language. #### Incompatible changes (usage): N.B. The javax.net.ssl properties have been moved from jmeter.properties to system.properties, and will no longer work if defined in jmeter.properties. The new arrangement is more flexible, as it allows arbitrary system properties to be defined. SSL session contexts are now created per-thread, rather than being shared. This generates a more realistic load for HTTPS tests. The change is likely to slow down tests with many SSL threads. The original behaviour can be enabled by setting the JMeter property:
>     https.sessioncontext.shared=true
> The LDAP Extended Sampler now uses the same panel for both Thread Bind and Single-Bind tests. This means that any tests using the Single-bind test will need to be updated to set the username and password. Bug 41140 : JMeterThread behaviour was changed so that PostProcessors are run in forward order (as they appear in the test plan) rather than reverse order as previously. The original behaviour can be restored by setting the following JMeter property: jmeterthread.reversePostProcessors=true The HTTP Authorization Manager now has extra columns for domain and realm, so the temporary work-round of using '\' and '@' in the username to delimit the domain and realm has been removed. Control + Z no longer used for Remote Start All - this now uses Control + Shift + R HttpClient now uses pre-emptive authentication. This can be changed by setting the following:
>     jmeter.properties:
>     httpclient.parameters.file=httpclient.parameters

>     httpclient.parameters:
>     http.authentication.preemptive$Boolean=false
The port field in HTTP Request Defaults is no longer ignored for https samplers if it is set to 80. #### Incompatible changes (development): N.B.The clear() method was defined in the following interfaces: Clearable, JMeterGUIComponent and TestElement. The methods serve different purposes, so two of them were renamed: the Clearable method is now clearData() and the JMeterGUIComponent method is now clearGui(). 3rd party add-ons may need to be rebuilt. Calculator and SamplingStatCalculator classes no longer provide any formatting of their data. Formatting should now be done using the jorphan.gui Renderer classes. Removed deprecated method JMeterUtils.split() - use JOrphanUtils version instead. Removed method saveUsingJPEGEncoder() from SaveGraphicsService. It was unused so far, and used the only Sun-specific class in JMeter. #### New functionality/improvements: Add Domain and Realm support to HTTP Authorization Manager HttpClient now behaves the same as the JDK http sampler for invalid certificates etc Added httpclient.parameters.file to allow HttpClient parameters to be defined Bug 33964 - Http Requests can send a file as the entire post body if name/type are omitted Bug 41705 - add content-encoding option to HTTP samplers for POST requests Bug 40933 ,Bug 40945 - optional RE matching when retrieving embedded resource URLs Bug 27780 - (patch 19936) create multipart/form-data HTTP request without uploading file Bug 42098 - Use specified encoding for parameter values in HTTP GET Bug 42506 - JMeter threads now use independent SSL sessions Bug 41707 - HTTP Proxy XML-RPC support Bug 41880 - Add content-type filtering to HTTP Proxy Server Bug 41876 - Add more options to control what the HTTP Proxy generates Bug 42158 - Improve support for multipart/form-data requests in HTTP Proxy server Bug 42173 - Let HTTP Proxy handle encoding of request, and undecode parameter values Bug 42674 - default to pre-emptive HTTP authorisation if not specified Support "file" protocol in HTTP Samplers Http Autoredirects are now enabled by default when creating new samplers Bug 40103 - various LDAP enhancements Bug 40369 - LDAP: Stable search results in sampler Bug 40381 - LDAP: more descriptive strings BeanShell Post-Processor no longer ignores samples with zero-length result data Added beanshell.init.file property to run a BeanShell script at startup Bug 39864 - BeanShell init files now found from current or bin directory BeanShell elements now support ThreadListener and TestListener interfaces BSF Sampler passes additional variables to the script Added timeout for WebService (SOAP) Sampler Bug 40825 - Add JDBC prepared statement support Extend JDBC Sampler: Commit, Rollback, AutoCommit Bug 41457 - Add TCP Sampler option to not re-use connections Bug 41522 - Use JUnit sampler name in sample results Bug 42223 - FTP Sampler can now upload files Bug 40804 - Change Counter default to max = Long.MAX_VALUE Use property jmeter.home (if present) to override user.dir when starting JMeter New -j option to easily change jmeter log file HTTP Mirror Server Workbench element Bug 41253 - extend XPathExtractor to work with non-NodeList XPath expressions Bug 42088 - Add XPath Assertion for booleans Added __V variable function to resolve nested variable names Bug 40369 - Equals Response Assertion Bug 41704 - Allow charset encoding to be specified for CSV DataSet Bug 41259 - Comment field added to all test elements Add standard deviation to Summary Report Bug 41873 - Add name to AssertionResult and display AssertionResult in ViewResultsFullVisualizer Bug 36755 - Save XML test files with UTF-8 encoding Use ISO date-time format for Tree View Listener (previously the year was not shown) Improve loading of CSV files: if possible, use header to determine format;

To revert to the previous behaviour, change the property sampleresult.timestamp.start to false (or comment it) The JMX output format has been simplified and files are not backwards compatible The JMeter.BAT file no longer changes directory to JMeter home, but runs from the current working directory. The jmeter-n.bat and jmeter-t.bat files change to the directory containing the input file. Listeners are now started slightly later in order to allow variable names to be used. This may cause some problems; if so define the following in jmeter.properties: jmeterengine.startlistenerslater=false The GUI now expands the tree by default when loading a test plan. This can be disabled by setting the JMeter property onload.expandtree=false #### Known problems: Post-processors run in reverse order (see Bug 41140 ) Module Controller does not work in non-GUI mode Aggregate Report and some other listeners use increasing amounts of memory as a test progresses Does not always handle non-default encoding properly Spaces in the installation path cause problems for client-server mode Change of Language does not propagate to all test elements SamplingStatCalculator keeps a List of all samples for calculation purposes; this can cause memory exhaustion in long-running tests Does not properly handle server certificates if they are expired or not installed locally #### New functionality: Report function XPath Extractor Post-Processor. Handles single and multiple matches. Simpler JMX file format (2.2) BeanshellSampler code can update ResponseData directly Bug 37490 - Allow UDV as delay in Duration Assertion Slow connection emulation for HttpClient Enhanced JUnitSampler so that by default assert errors and exceptions are not appended to the error message.

Missing start/end times in scheduler are assumed to be now, not 1970 Bug 28661 - 304 responses not appearing in listeners DOS scripts now handle different disks better Bug 32345 - HTTP Rewriter does not work with HTTP Request default Catch Runtime Exceptions so an error in one Listener does not affect others Bug 33467 - __threadNum() extracted number wrongly Bug 29186 ,33299 - fix CLI parsing of "-" in second argument Fix CLI parse bug: -D arg1=arg2. Log more startup parameters. Fix JTidy and HTMLParser parsers to handle form src= and link rel=stylesheet JMeterThread now logs Errors to jmeter.log which were appearing on console Ensure WhileController condition is dynamically checked Bug 32790 ensure If Controller condition is re-evaluated each time Bug 30266 - document how to display proxy recording responses Bug 33921 - merge should not change file name Close file now gives chance to save changes Bug 33559 - fixes to Runtime Controller #### Other changes: To help with variable evaluation, JMeterThread sets "sampling started" a bit earlier (see jmeter.properties) Bug 33796 - delete cookies with null/empty values Better checking of parameter count in JavaScript function Thread Group now defaults to 1 loop instead of forever All Beanshell access is now via a single class; only need BSH jar at run-time Bug 32464 - document Direct Draw settings in jmeter.bat Bug 33919 - increase Counter field sizes Bug 32252 - ForEach was not initialising counters ### Version 2.0.2 #### New functionality: While Controller BeanShell initialisation scripts Result Saver can optionally save failed results only Display as HTML has option not to download frames and images etc Multiple Tree elements can now be enabled/disabled/copied/pasted at once __split() function added Bug 28699 allow Assertion to regard unsuccessful responses - e.g. 404 - as successful Bug 29075 Regex Extractor can now extract data out of http response header as well as the body __log() functions can now write to stdout and stderr URL Modifier can now optionally ignore query parameters #### Bug fixes: If controller now works after the first false condition Bug 31390 Regex GUI was losing track of Header/Body checkbox Bug 29853 Display as HTML now handles frames and relative images Right-click open replaced by merge Fix some drag and drop problems Fixed foreach demo example so it works Bug 30741 SSL password prompt now works again StringFromFile now closes files at end of test; start and end now optional as intended Bug 31342 Fixed text of SOAP Sampler headers Proxy must now be stopped before it can be removed Bug 25145 Link Parser now supports BASE href Bug 25490 Bug 30917 Classfinder ignores duplicate names Bug 22820 Allow Counter value to be cleared Bug 28230 Fix NPE in HTTP Sampler retrieving embedded resources Improve handling of StopTest; catch and log some more errors ForEach Controller no longer runs any samples if first variable is not defined Bug 28663 NPE in remote JDBC execution Bug 30110 Deadlock in stopTest processing Bug 31696 Duration not working correctly when using Scheduler JMeterContext now uses ThreadLocal - should fix some potential NPE errors ### Version 2.0.1 Bug fix release. TBA. ### Version 2.0 HTML parsing improved; now has choice of 3 parsers, and most embedded elements can now be detected and downloaded. Redirects can now be delegated to URLConnection by defining the JMeter property HTTPSamper.delegateRedirects=true (default is false) Stop Thread and Stop Test methods added for Samplers and Assertions etc. Samplers can call setStopThread(true) or setStopTest(true) if they detect an error that needs to stop the thread of the test after the sample has been processed Thread Group Gui now has an extra pane to specify what happens after a Sampler error: Continue (as now), Stop Thread or Stop Test. This needs to be extended to a lower level at some stage. Added Shutdown to Run Menu. This is the same as Stop except that it lets the Threads finish normally (i.e. after the next sample has been completed) Remote samples can be cached until the end of a test by defining the property hold_samples=true when running the server. More work is needed to be able to control this from the GUI Proxy server has option to skip recording browser headers Proxy restart works better (stop waits for daemon to finish) Scheduler ignores start if it has already passed Scheduler now has delay function added Summariser test element (mainly for non-GUI) testing. This prints summary statistics to System.out and/or the log file every so often (3 minutes by default). Multiple summarisers can be used; samples are accumulated by summariser name. Extra Proxy Server options: Create all samplers with keep-alive disabled Add Separator markers between sets of samples Add Response Assertion to first sampler in each set Test Plan has a comment field Help Page can now be pushed to background Separate Function help page New / amended functions __property() and __P() functions __log() and __logn() - for writing to the log file _StringFromFile can now process a sequence of files, e.g. dir/file01.txt, dir/file02.txt etc _StringFromFile() function can now use a variable or function for the file name New / amended Assertions Response Assertion now works for URLs, and it handles null data better Response Assertion can now match on Response Code and Response message as well HTML Assertion using JTidy to check for well-formed HTML If Controller (not fully functional yet) Transaction Controller (aggregates the times of its children) New Samplers Basic BSF Sampler (optional) BeanShell Sampler (optional, needs to be downloaded from www.beanshell.org Basic TCP Sampler Optionally start BeanShell server (allows remote access to JMeter variables and methods) ### Version 1.9.1 TBA ### Version 1.9 Sample result log files can now be in CSV or XML format New Event model for notification of iteration events during test plan run New Javascript function for executing arbitrary javascript statements Many GUI improvements New Pre-processors and Post-processors replace Modifiers and Response-Based Modifiers. Compatible with jdk1.3 JMeter functions are now fully recursive and universal (can use functions as parameters to functions) Integrated help window now supports hypertext links New Random Function New XML Assertion New LDAP Sampler (alpha code) New Ant Task to run JMeter (in extras folder) New Java Sampler test implementation (to assist developers) More efficient use of memory, faster loading of .jmx files New SOAP Sampler (alpha code) New Median calculation in Graph Results visualizer Default config element added for developer benefit Various performance enhancements during test run New Simple File recorder for minimal GUI overhead during test run New Function: StringFromFile - grabs values from a file New Function: CSVRead - grabs multiple values from a file Functions now longer need to be encoded - special values should be escaped with "\" if they are literal values New cut/copy/paste functionality SSL testing should work with less user-fudging, and in non-gui mode Mailer Model works in non-gui mode New Throughput Controller New Module Controller Tests can now be scheduled to run from a certain time till a certain time Remote JMeter servers can be started from a non-gui client. Also, in gui mode, all remote servers can be started with a single click ThreadGroups can now be run either serially or in parallel (default) New command line options to override properties New Size Assertion ### Version 1.8.1 Bug Fix Release. Many bugs were fixed. Removed redundant "Root" node from test tree. Re-introduced Icons in test tree. Some re-organization of code to improve build process. View Results Tree has added option to view results as web document (still buggy at this point). New Total line in Aggregate Listener (still buggy at this point). Improvements to ability to change JMeter's Locale settings. Improvements to SSL Manager. ### Version 1.8 Improvement to Aggregate report's calculations. Simplified application logging. New Duration Assertion. Fixed and improved Mailer Visualizer. Improvements to HTTP Sampler's recovery of resources (sockets and file handles). Improving JMeter's internal handling of test start/stop. Fixing and adding options to behavior of Interleave and Random Controllers. New Counter config element. New User Parameters config element. Improved performance of file opener. Functions and other elements can access global variables. Help system available within JMeter's GUI. Test Elements can be disabled. Language/Locale can be changed while running JMeter (mostly). View Results Tree can be configured to record only errors. Various bug fixes. ### Version 1.7.3 New Functions that provide more ability to change requests dynamically during test runs. New language translations in Japanese and German. Removed annoying Log4J error messages. Improved support for loading JMeter 1.7 version test plan files (.jmx files). JMeter now supports proxy servers that require username/password authentication. Dialog box indicating test stopping doesn't hang JMeter on problems with stopping test. GUI can run multiple remote JMeter servers (fixes GUI bug that prevented this). Dialog box to help created function calls in GUI. New Keep-alive switch in HTTP Requests to indicate JMeter should or should not use Keep-Alive for sockets. HTTP Post requests can have GET style arguments in Path field. Proxy records them correctly now. New User-defined test-wide static variables. View Results Tree now displays more information, including name of request (matching the name in the test tree) and full request and POST data. Removed obsolete View Results Visualizer (use View Results Tree instead). Performance enhancements. Memory use enhancements. Graph visualizer GUI improvements. Updates and fixes to Mailer Visualizer. ### Version 1.7.2 JMeter now notifies user when test has stopped running. HTTP Proxy server records HTTP Requests with re-direct turned off. HTTP Requests can be instructed to either follow redirects or ignore them. Various GUI improvements. New Random Controller. New SOAP/XML-RPC Sampler. ### Version 1.7.1 JMeter's architecture revamped for a more complete separation between GUI code and test engine code. Use of Avalon code to save test plans to XML as Configuration Objects All listeners can save data to file and load same data at later date. ### Version 1.7Beta Better XML support for special characters (Tushar Bhatia) Non-GUI functioning & Non-GUI test plan execution (Tushar Bhatia) Removing Swing dependence from base JMeter classes Internationalization (Takashi Okamoto) AllTests bug fix (neth6@atozasia.com) ClassFinder bug fix (neth6@atozasia.com) New Loop Controller Proxy Server records HTTP samples from browser (and documented in the user manual) Multipart Form support HTTP Header class for Header customization Extracting HTTP Header information from responses (Jamie Davidson) Mailer Visualizer re-added to JMeter JMeter now url encodes parameter names and values listeners no longer give exceptions if their gui's haven't been initialized HTTPS and Authorization working together New Http sampling that automatically parses HTML response for images to download, and includes the downloading of these images in total time for request (Neth neth6@atozasia.com) HTTP responses from server can be parsed for links and forms, and dynamic data can be extracted and added to test samples at run-time (documented) New Ramp-up feature (Jonathan O'Keefe) New visualizers (Neth) New Assertions for functional testing ### Version 1.6.1 Fixed saving and loading of test scripts (no more extra lines) Can save and load special characters (such as "&" and "<"). Can save and load timers and listeners. Minor bug fix for cookies (if you cookie value contained an "=", then it broke). URL's can sample ports other than 80, and can test HTTPS, provided you have the necessary jars (JSSE) ### Version 1.6 Alpha New UI Separation of GUI and Logic code New Plug-in framework for new modules Enhanced performance Layering of test logic for greater flexibility Added support for saving of test elements Added support for distributed testing using a single client ### Version 1.5.1 Fixed bug that caused cookies not to be read if header name case not as expected. Clone entries before sending to sampler - prevents relocations from messing up information across threads Minor bug fix to convenience dialog for adding parameters to test sample. Bug prevented entries in dialog from appearing in test sample. Added xerces.jar to distribution Added junit.jar to distribution and created a few tests. Started work on new framework. New files in cvs, but do not effect program yet. Fixed bug that prevent HTTPJMeterThread from delaying according to chosen timer. ### Version 1.5 Abstracted out the concept of the Sampler, SamplerController, and TestSample. A Sampler represents code that understands a protocol (such as HTTP, or FTP, RMI, SMTP, etc..). It is the code that actually makes the connection to whatever is being tested. A SamplerController represents code that understands how to organize and run a group of test samples. It is what binds together a Sampler and its test samples and runs them. A TestSample represents code that understands how to gather information from the user about a particular test. For a website, it would represent a URL and any information to be sent with the URL. The UI has been updated to make entering test samples more convenient. Thread groups have been added, allowing a user to setup multiple test to run concurrently, and to allow sharing of test samples between those tests. It is now possible to save and load test samples. … and many more minor changes/improvements … Apache JMeter 1.4.1-dev Cleaned up URLSampler code after tons of patches for better readability.
