Reltool Release Notes

Håkan Mattsson
notes.xml

This document describes the changes made to the Reltool system from version to version. The intention of this document is to list all incompatibilities as well as all enhancements and bugfixes for every release of Reltool. Each release of Reltool thus constitutes one section in this document. The title of each section is the version number of Reltool.

## Reltool 0.5.5

### Fixed Bugs and Malfunctions

The reltool module contained two seriously erroneous specs which caused bogus warnings when dialyzing reltool and some correct code of users. These were fixed (specs for start_link/1 and eval_server/3)

- Code cleanups and simplifications - Fix a bug in the calculation of circular dependencies - Eliminate two dialyzer warnings - Put files alphabetically

## Reltool 0.5.4

### Improvements and New Features

Added function zip:foldl/3 to iterate over zip archives.

Added functions to create and extract escripts. See escript:create/2 and escript:extract/2.

The undocumented function escript:foldl/3 has been removed. The same functionality can be achieved with the more flexible functions escript:extract/2 and zip:foldl/3.

Record fields has been annotated with type info. Source files as been adapted to fit within 80 chars and trailing whitespace has been removed.

A new escript, called reltool, has been introduced in order to simplify the usage of the reltool application from makefiles.

The handling of applications included in releases has been improved. Applications that are required to be started before other applications in a release are now automatically included in the release. The kernel and stdlib applications are always included as they are mandatory.

Applications that are (explicitly or implicitly) included in a release are now automatically included as if they were explicitly included with the incl_cond flag.

A new embedded_app_type option has been introduced. It is intended to be used for embedded systems where all included applications must be loaded from the boot script, as these systems does not utilize dynamic code loading. If embedded_app_type is set to something else than undefined, all included applications will be included in both the release as well as in the boot script. If the profile is embedded the embedded_app_type option defaults to load.

A new function called reltool:get_status/1 has been introduced. It returns status about the configuration in the server.

The API functions that may take PidOrOptions as input and actually gets Options does now print out warnings.

The internal error handling has been improved. For example {error,Reason} is always returned in case of errors even when the server dies.

app and appup files has been added as well as a corresponding test suite.

Various cleanups has been made in the code and in the documentation.

## Reltool 0.5.2

### Improvements and New Features

The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the HTML frames are removed.

## Reltool 0.5.1

### Fixed Bugs and Malfunctions

In the new release of Reltool (0.5) there is a severe bug that may cause your source files to be deleted. The bug is triggered when you generate a target system WITH archive files AND your library directories are given with absolute paths. (Library directories are given with the ERL_LIBS environment variable or with the lib_dirs configuration parameter.)

## Reltool 0.5

### Improvements and New Features

The tool is still experimental. Feedback is appreciated.

Major improvements of the target system generation has been performed. Now it is possible to generate a relocatable target system that does not need to be re-installed if it is moved to a new location. Archive files are automatically generated. A detailed specification of the target system can be generated without actually creating the target system. Relocatable escripts are put in the bin directory of the target system. etc. etc.

Some new functions has been introduced in the reltool module: start/1, start_link/1, get_config/3, get_target_spec/1 and eval_target_spec/3.

Some new configuration parameters has been introduced: profile, incl_sys_filters, excl_sys_filters, incl_app_filters, excl_app_filters, incl_archive_filters, excl_archive_filters, archive_opts, escript and relocatable.

Some parameters have been obsoleted and given new semantics: incl_erts_dirs (incl_sys_filters), excl_erts_dirs (excl_sys_filters), incl_app_dirs (incl_app_filters), excl_app_dirs (excl_app_filters) and escripts (escript).
