2.2.0 | 2021-12-20 19:32:33 -0800

  * Merge branch 'topic/christian/fix-python-unhashables' (Christian Kreibich, Corelight)

    * topic/christian/fix-python-unhashables:
      Add testcases for new Python SafeSubscriber class
      Provide a SafeSubscriber class in Python to accommodate non-hashable types
      Add immutable values to Python data type testsuite
      Python cleanup: remove unneeded semicolons and trailing whitespace

  * Add testcases for new Python SafeSubscriber class (Christian Kreibich, Corelight)

  * Provide a SafeSubscriber class in Python to accommodate non-hashable types (Christian Kreibich, Corelight)

    Broker's data model supports nested complex types, such as a set with table
    members. When rendering such structures into Python, this could trigger
    TypeError exceptions due to unhashable types.

    The SafeSubscriber class and the corresponding Endpoint.make_safe_subscriber()
    method ensure that immutable (hashable) Python types get used and that the
    returned values are read-only. For sets the frozenset type achieves this, for
    mapping types it's types.MappingProxyType. The API now also supports the latter
    two types as inputs.

  * Add immutable values to Python data type testsuite (Christian Kreibich, Corelight)

  * Change how actor_system_config::config_file_path is set (Jon Siwek, Corelight)

    Mainly avoid conflict with an upcoming change

2.1.0-dev.66 | 2021-05-24 15:01:34 -0700

  * Update embedded CAF to 0.18.3 (Jon Siwek, Corelight)

2.1.0-dev.54 | 2021-03-02 19:59:06 -0700

  * Add lgtm configuration (Tim Wojtulewicz, Corelight)

2.1.0-dev.52 | 2021-02-26 17:57:58 -0800

  * Increase CPUs used for macOS CI builds (Jon Siwek, Corelight)

2.1.0-dev.47 | 2021-02-16 12:30:36 -0800

  * broker-benchmark: Fix heap-buffer overflow when receiving stats (Dominik Charousset, Corelight)

  * Fix metrics and TTL of locally published data (Dominik Charousset, Corelight)

  * Implement more lightweight origin credit tracking (Dominik Charousset, Corelight)

    The item-based tracking of message origins keeps all context for input
    messages. However, benchmarking reveled that this nice-to-have property
    comes at an expensive price.

    The new approach for tracking how many inputs for each origin are
    currently in the system leverages the reference count of Broker messages
    that we need in any case rather than introducing additional state.

  * Disable background deserialization (Dominik Charousset, Corelight)

    Zeek configures only a few threads to the CAF thread pool. This may
    introduce some heavy delays for the deserialization that takes place in
    the background. Disabling this feature altogether makes sure that
    messages will not end up in some queues even though it puts more
    pressure on the multiplexer's thread.

2.1.0-dev.42 | 2021-02-11 12:10:05 -0800

  * Disable syntax highlighting for some overview documentation (Jon Siwek, Corelight)

  * Update embedded CAF to 0.18 (Jon Siwek, Corelight)

  * Add CI support for running cluster benchmarks (Tim Wojtulewicz, Corelight)

2.1.0-dev.33 | 2021-01-21 16:15:32 -0800

  * Fix deprecation warnings with latest CAF (Dominik Charousset, Corelight)

  * Clean up remaining caf::hash::fnv TODO (Dominik Charousset, Corelight)

    CAF 0.18 introduced an FNV hashing visitor that we can use instead of
    rolling custom hash algorithms and hash combinators.

  * Replace unsafe (to|from)_blob functions (Dominik Charousset, Corelight)

    The utility functions `to_blob` and `from_blob` in
    `broker/detail/blob.hh` silently ignored any error during serialization
    and deserialization. Since the functions were only used by the SQLite
    backend, the new implementations with proper error propagation (and
    cleaned up interface) moved to `sqlite_backend.cc`.

2.1.0-dev.27 | 2021-01-19 21:07:18 -0800

  * Update Cirrus CI naming for MacOS images (Christian Kreibich, Corelight)

    The docs on https://cirrus-ci.org/guide/macOS/ changed from
    "osx_instance" to "macos_instance", so let's reflect that.

2.1.0-dev.25 | 2021-01-12 20:19:56 -0800

  * GH-165: Fix possible deadlock by implementing new origin-based credit strategy (Dominik Charousset, Corelight)

  * Remove deprecated broker::memory/broker::sqlite enums (Jon Siwek, Corelight)

  * Remove unused and broken rocksdb backend (Dominik Charousset, Corelight)

2.1.0-dev.12 | 2021-01-04 15:40:56 -0800

  * broker-cluster-benchmark: Fix type mismatch and potential cleanup issue (Dominik Charousset, Corelight)

2.1.0-dev.10 | 2020-12-23 10:13:37 -0800

  * Call `ctest` instead of `make test` in CI builds (Dominik Charousset, Corelight)

    Setting `CTEST_OUTPUT_ON_FAILURE` and then calling `make test` seems to
    lose the flag at some point. Calling `ctest` directly and passing
    `--output-on-failure` makes sure that we actually get the test output in
    case of an error.

2.1.0-dev.8 | 2020-12-21 10:53:48 -0800

  * Add macOS Big Sur to CI (Jon Siwek, Corelight)

2.1.0-dev.6 | 2020-12-17 16:04:25 -0800

  * Remove explicit use of config mode for finding CAF (Dominik Charousset, Corelight)

2.1.0-dev.4 | 2020-12-17 10:36:12 -0700

  * Fix CAF configuration parameter names (Dominik Charousset, Corelight)

2.1.0-dev.2 | 2020-12-16 15:04:30 -0800

  * Make sure status updates are visible before data (Dominik Charousset, Corelight)

2.1.0-dev | 2020-12-14 20:16:02 -0800

  * Update NEWS for start of v2.1.0 development (Jon Siwek, Corelight)

1.5.0-dev.63 | 2020-12-14 10:38:14 -0800

  * Update CAF submodule to fix handling of --libdir (Jon Siwek, Corelight)

1.5.0-dev.62 | 2020-12-12 18:28:25 -0800

  * Change `configure --prefix` to not set CMAKE_INSTALL_LIBDIR (Jon Siwek, Corelight)

    In places where that libdir option is used and not explicitly set
    before, it will already correctly prepend CMAKE_INSTALL_PREFIX.  Having
    the configure script use the hardcoded 'lib' also prevented the
    automatic use of 'lib64' on platforms that prefer it.

1.5.0-dev.61 | 2020-12-10 14:07:51 -0800

  * Add Jenkinsfile for re-enabling Windows builds (Dominik Charousset, Corelight)

  * Add Python context manager support (Dominik Charousset, Corelight)

    For proper resource management/cleanup, the Python API now requires
    using Endpoint, Subscriber, StatusSubscriber, and Store objects within a
    `with` statement or alternatively doing an explicit call to the
    ``reset()`` method of subscriber/store objects before the associated
    Endpoint's ``shutdown()`` method.

  * Disable Windows builds via Travis CI (Dominik Charousset, Corelight)

    Remove the YAML file for Travis CI due to issues with getting Visual
    Studio 2019 with support for `std::filesystem` working on Travis. This
    is supposed to be a temporary measure until either finding a fix for the
    setup or re-enabling Windows build through some other means.

1.5.0-dev.20 | 2020-10-21 15:14:55 -0700

  * Update Windows CI config (Jon Siwek, Corelight)

    * Disable Cirrus Windows task: an updated Docker image on Cirrus-side
      has unknown issues and trying to create one for ourselves also ended
      with similar, unsuccessful results

    * Provide an example Dockerfile that uses Visual Studio 2019, which may
      help as a starting point for manual testing/development purposes

    * Enable Travis for testing just Windows

1.5.0-dev.16 | 2020-08-21 11:41:06 -0700

  * Respect --config-file= CLI parameters (Dominik Charousset, Corelight)

1.5.0-dev.14 | 2020-07-30 16:08:56 -0700

  * Fix build with CAF 0.18 (Dominik Charousset)

1.5.0-dev.12 | 2020-07-27 18:17:13 -0700

  * Use 127.0.0.1 instead of ::1 for cluster configs (Dominik Charousset)

  * Call abort() on errors during cluster benchmarks (Dominik Charousset)

    Orderly shutdowns seem to fail for some categories of errors. Calling
    `abort` ensures that the program at least always terminates, even though
    this means skipping cleanup of system resources such as open ports.

  * Make cluster-benchmark tool modular, add new mode (Dominik Charousset)

    Rather than using flags to change the behavior, the configuration of the
    tool now asks for a mode. This makes the tool easier to extend and use.
    Previously the behavior of mutualy exclusive flags (for example, setting
    both `--generate-config` and `--dump-stats`) was not well defined.

    Furthermore, this commits adds another mode: `shrink-generator-file`.
    This enables users to reduce the size of recordings retrospectively.

  * Add factory function for creating generator file headers (Dominik Charousset)

  * Add new read_raw method to expose generator file input bytes (Dominik Charousset)

  * Make broker-cluster-benchmark config file output independent of argv order (Dominik Charousset)

  * Include store IDs in the topic (Dominik Charousset)

    As discussed in #121, adding the store ID to the topic enables better
    control over the amount of data a subscriber receives by selecting only
    stores of interest.

1.4.0-dev.148 | 2020-06-23 16:10:07 -0700

  * Bump required CAF version to >= 0.17.5 (Dominik Charousset)

  * Update CAF submodule (Dominik Charousset)

  * Port Broker to CAF 0.18 (Dominik Charousset)

    With the new forward compatibility macros in CAF 0.17.5, we can support
    both CAF releases with a few select #ifdef blocks until switching fully
    to CAF 0.18.

  * Switch to _v suffix notation for atoms (Dominik Charousset)

  * Use inheritance for composing the core manager (Dominik Charousset)

  * Refactor streaming scaffold (Dominik Charousset)

    - Bundle streaming logic in new alm::stream_transport class
    - Inherit from `caf::stream_manager` directly
    - Remove the obsolete `stream_distribution_tree`

  * Templatize the core policy (Dominik Charousset)

  * Generalize node_message (Dominik Charousset, Corelight)

  * Fix subscription management with filter_extend (Dominik Charousset, Corelight)

1.4.0-dev.105 | 2020-04-30 16:37:21 -0700

* Allow users to subscribe to data store "update events" (Dominik Charousset)

  By subscribing to the new (reserved) topic topics::store_events, users can
  now get insert, update, and erase events whenever values in the store are
  added, changed, or removed::

    auto x = subscriber.get();
    if (auto insert = store_event::insert::make(x)) {
      // ...
    }
    // ... same for store_event::update and store_event::erase ...

1.4.0-dev.85 | 2020-04-29 15:17:53 -0700

  * Add new status codes for node discovery (Dominik Charousset)

    The new status codes are currently unused, but become relevant when
    switching to the ALM-based communication backend.

1.4.0-dev.81 | 2020-04-15 15:10:37 -0700

  * GH-109: fix unusable subscriber.poll() method in Python bindings (Jon Siwek, Corelight)

  * GH-106: Fix Python tests to work with Python 3.8 (Jon Siwek, Corelight)

  * Change topic strings to not automatically alter slashes (Jon Siwek, Corelight)

    Automatically removing trailing or consecutive slashes in topic strings
    prevents uniquely targeting topic names to a node.

    For example, publishing to "node-10/" should not match a subscription
    for "node-1/", but that's what happens with prefix-based matching if the
    trailing slash is automatically removed.

1.4.0-dev.77 | 2020-04-09 22:57:15 -0700

  * Fix concurrency setup for the Cirrus/MSVC build (Dominik Charousset)

1.4.0-dev.75 | 2020-03-30 13:21:09 -0700

  * Make RocksDB usage opt-in and add --enable-rocksdb configure flag
    (Jon Siwek, Corelight)

1.4.0-dev.73 | 2020-03-27 11:11:51 -0700

  * Add missing binding for broker_options member (Dominik Charousset)

  * Update CAF submodule to fix MSVC/Windows build (Dominik Charousset)

1.4.0-dev.69 | 2020-03-26 12:00:05 -0700

1.4.0-dev.65 | 2020-03-13 22:21:28 -0700

  * Add Windows task to Cirrus CI config (Jon Siwek, Corelight)

    This also moves the CAF submodule from aux/caf/ to caf/ since
    Windows does not allow naming a directory "aux".

1.4.0-dev.63 | 2020-03-13 13:38:40 -0700

  * Add branch whitelist for CI notifications (Jon Siwek, Corelight)

1.4.0-dev.62 | 2020-03-09 19:21:47 -0700

  * Add Cirrus CI config and remove Travis CI config (Jon Siwek, Corelight)

    The CMake configuration also now prefers choosing a Python3 installation
    over Python2 (since that's end-of-life) for building the Broker Python
    bindings.

    Some timeout values in unit tests were also fiddled to work better in
    the CI environment.

1.4.0-dev.60 | 2020-03-09 12:54:05 -0700

  * Fix a race condition in data store flare operations (Jon Siwek, Corelight)

    The race (as seen via Zeek usage) goes like:

    Thread A: enqueue item, get suspended
    Thread B: sees mailbox has items
    Thread B: dequeue item
    Thread B: extinguish flare
    Thread A: resume, fire flare

    That ordering can leave the flare in an active state without any actual
    items remaining in the mailbox.

    This patch adds a mutex/lock such that extinguishing of the flare cannot
    be interleaved between the enqueue and firing of the flare.

    This likely relates to https://github.com/zeek/zeek/issues/838,
    https://github.com/zeek/zeek/issues/716, as well as this thread
    http://mailman.icsi.berkeley.edu/pipermail/zeek/2020-February/015062.html

1.4.0-dev.58 | 2020-03-06 11:53:58 -0800

  * Send statuses and errors via regular topics (Dominik Charousset)

    With this set of changes, status and error messages no longer bypass the
    regular topic-based distribution. There are two new reserved topics:
    topics::statuses and topics::errors. Messages to these two topics are never
    forwarded to peers.

    When emitting status or error messages, they get converted to data, which
    is a vector.  The new conversions between status <-> data and error <->
    data actually accounts for the most code changes. However, this means
    scripts can now easily access these messages as well. Subscribing to the
    reserved topics grants easy access to statuses and errors now, allowing to
    multiplex them with regular events.

    The status_subscriber was rewritten to dispatch to a regular subscriber
    internally.

  * Implement conversion between error and data (Dominik Charousset)

  * Implement can_convert_to for endpoint_info (Dominik Charousset)

  * Add declarative inspection of data via contains<> (Dominik Charousset)

  * Make ec convertible to and from string (Dominik Charousset)

  * Add status_view type for operating on raw data (Dominik Charousset)

  * Implement conversion between data and status (Dominik Charousset)

  * Add from-string conversion to sc enum (Dominik Charousset)

1.4.0-dev.38 | 2020-03-06 10:39:42 -0800

  * Fix cross compilation build (Dominik Charousset)

1.4.0-dev.35 | 2020-03-02 11:40:53 -0800

1.4.0-dev.32 | 2020-03-02 10:30:03 -0800

  * Check in CMake whether the <filesystem> code links (Dominik Charousset)

  * Add instructions for MSVC builds (Dominik Charousset)

  * Improve error logging in the SQLite backend (Dominik Charousset)

  * Port the flare to Windows/MSVC (Dominik Charousset)

    The `pipe` system call only exists on POSIX. On Windows, we need to
    create a pair of connected sockets. Also, file descriptors and sockets
    are different things on Windows.

    Fortunately, CAF already offers a set of abstractions we can use to
    adjust for the platform differences. We still have to make sure to use
    recv/send on Windows instead of read/write as well as calling WSAStartup
    and WSACleanup.

  * Port recording utilities to Windows (Dominik Charousset)

  * Port filesystem wrapper to Windows/MSVC (Dominik Charousset)

  * Reimplement address with caf::ip_address for MSVC (Dominik Charousset)

    The implementation of `broker::address` used many  UNIX-specific
    functions as well as functions marked as deprecated/unsafe on MSVC (e.g.
    `sprintf`). Basing the implementation on `caf::ip_address` instead of
    rolling a custom implementation avoids dealing with most issues in the
    first place.

  * Add MSVC to the CMake build harness (Dominik Charousset)

1.4.0-dev.18 | 2020-02-28 13:22:09 -0800

  * Fix handling of OS-specific threading flags (Dominik Charousset)

1.4.0-dev.15 | 2020-02-25 17:56:28 -0800

  * Support building Broker as CMake subdirectory (Dominik Charousset)

    When building Broker as a subdirectory, we disable all compiler checks
    and flag management and leave it to the parent project to provide valid
    settings. In order to achieve "perfect forwarding" of all settings, we
    include CAF as subdirectory rather than bundling it as an external
    project.

1.4.0-dev.4 | 2020-02-22 11:54:14 -0800

  * Fix various "maybe uninitialized" warnings (Jon Siwek, Corelight)

1.2.0-154 | 2020-02-04 11:33:03 +0000

  * GH-85: Improve Python bindings Event validity checks. (Jon Siwek,
    Corelight)

    This adds a valid() method to broker.zeek.Event objects that may be
    called after creating them to check if the data it parsed was valid
    event data.

    Also extended the name() and args() methods of broker.zeek.Event to
    first check for validity to avoid segfaulting.  If the validity check
    fails, a ValueError exception is now thrown.

1.2.0-151 | 2020-01-24 12:04:26 -0800

  * Fix accidential error/log output (Dominik Charousset, Corelight)

  * Extend log output format on the console (Dominik Charousset, Corelight)

1.2.0-147 | 2020-01-23 13:33:04 +0000

  * Redesign Broker's configuration setup. (Dominik Charousset, Corelight)

    The environment variables BROKER_DEBUG_VERBOSE and
    BROKER_DEBUG_LEVEL overlapped and provided fuzzy semantics for a
    user. This commit replaces the previous variables with
    BROKER_CONSOLE_VERBOSITY and BROKER_FILE_VERBOSITY:

    - set `BROKER_CONSOLE_VERBOSITY=info` for seeing high-level events such
      as new connections, incoming peerings, etc.
    - set `BROKER_CONSOLE_VERBOSITY=debug` for tapping into exchanged
      messages and other low-level events (slow)

    When debugging a distributed Broker setup, users can instead use
    BROKER_FILE_VERBOSITY to record a test run and then collect the files
    from all endpoints.

    In all cases, Broker now omits CAF output. Advanced features are only
    accessible from the (new) `broker.conf`. Here, experienced users can
    remove the component files, tweak format strings, and so on.

    The initialization process now also fixes ordering of the various
    configuration parameters:

    - `broker.conf` overrides hard-coded defaults
    - environment variables override `broker.conf` entires
    - command line arguments override environment variables

    Finally, Broker now throws exceptions on invalid configuration entries
    rather than silently dropping them. Also, the `endpoint` checks whether
    the user asked for a help text and stops immediately instead of carrying
    on normally.

1.2.0-141 | 2020-01-07 20:45:15 -0800

  * Preserve optimization setting for sanitizer build (Jon Siwek, Corelight)

1.2.0-140 | 2020-01-03 10:45:38 -0700

  * Add LeakSanitizer instrumentation macros

    And disable checking LSAN leaks of sqlite3_open which seems to be a
    false positive. (Jon Siwek, Corelight)

  * Improve convenience options for enabling sanitizers

    * Removes --enable-asan configure flag
    * Removes ENABLE_ADDRESS_SANITIZER CMake variable
    * Adds --sanitizers configure flag
    * Adds BROKER_SANITIZERS CMake variable
    * Sets C++ compiler flags according to the new options and also passes
      them to the embedded CAF project

    These new options would typically be used with the Debug build type and
    also automatically sets -O1 unless NO_OPTIMIZATIONS environment variable
    exists.

1.2.0-135 | 2019-11-24 10:13:37 -0800

  * Use binary serializers, prepare for CAF changes (Dominik Charousset, Corelight)

    - The stream serializers perform poorly and probably disappear in the
      next CAF release. Consequently, always using the binary serializers
      improves performance and also makes sure Broker is "future proof".
    - Legacy support for serialize() functions probably fades away and
      mixing `inspect` and `serialize` functions in Broker only has historic
      reasons anyway. Sicking to one abstraction (`inspect`) is overdue.
    - The binary_serializer might use any buffer type in future releases.
      Instead of hardcoding `vector<char>`, we now ask the serializer for
      its container type.

  * Set CMAKE_INSTALL_LIBDIR in CAF if set in broker/zeek (Johanna Amann, Corelight)

    The INSTALL_LIB_DIR CMake variable was also removed in favor of

  * Require CMake 3 (Dominik Charousset, Corelight)

  * Fix position of CMake project() (Dominik Charousset, Corelight)

    The call to `project` must come after `cmake_minimum_required` in CMake
    in order to get the correct policy settings.

  * Fix conditions where broker-cluster-benchmark may hang (Dominik Charousset, Corelight)

1.2.0-108 | 2019-10-28 16:08:14 -0700

  * Use Ubuntu 18.04 (Bionic) for Travis CI (Jon Siwek, Corelight)

    Mostly as a simple way to get a C++17-capable compiler in the default
    build environment.

  * Require C++17 (Jon Siwek, Corelight)

1.2.0-102 | 2019-10-23 09:16:09 -0700

  * Add -DNO_AUTO_LIBCPP when building CAF. (Robin Sommer, Corelight)

    When setting the C++ compiler to clang, CAF by default switches to
    compiling with -stdlib=libc++. As Broker doesn't do that, the two end
    up linking against different libaries. Setting NO_AUTO_LIBCPP lets CAF
    use the same library settings as Broker.

1.2.0-100 | 2019-10-21 17:35:16 -0700

  * Add broker-cluster-benchmark tool (Dominik Charousset, Corelight)

    Allows benchmarking arbitrary Broker networks based on previously
    recorded data.  e.g. can record all Broker messages in a Zeek cluster
    and then replay them later in a simulated network for benchmarking
    purposes.  See tests/benchmark/README.md for details.

  * Add new is_file utility function (Dominik Charousset, Corelight)

  * Remove obsolete benchmark (Dominik Charousset, Corelight)

    The old broker-stream-benchmark is very low level and no longer provides
    any value with broker-cluster-benchmark in the mix.

  * Give recognizable names to custom actor types (Dominik Charousset, Corelight)

  * Streamline announcement of types (Dominik Charousset, Corelight)

  * GH-51: move Broker header files into include/ subdir (Jon Siwek, Corelight)

    So that project root directory doesn't need to be in search path
    (which potentially has non-header files whose name may collide with
    the intended header file from standard).

1.2.0-31 | 2019-09-04 15:30:51 -0700

  * Add option to record metadata for published messages (Dominik Charousset)

1.2.0-12 | 2019-09-04 13:38:42 -0700

  * Always disable OpenSSL in test fixture (Dominik Charousset)

  * Make logging code more robust (Dominik Charousset)

    Setting CAF_LOG_COMPONENT is very brittle and CAF is moving away from
    this design for that reason. Instead, we now dispatch directly to
    CAF_LOG_IMPL with the proper log component and level.

    Also, we no longer use CAF_LOG_* macros directly and instead always use
    the Broker macros in order to make sure log entries are properly
    attributed to either CAF or Broker code.

  * Rename test.[hc]pp according to naming convention (Dominik Charousset)

1.2.0-6 | 2019-09-03 11:32:35 -0700

  * Review broker-benchmark, remove dead/unsafe code (Dominik Charousset)

    - Remove 'use-non-blocking' mode, since it is unsafe. Once the queue gets
      exhausted, CAF will halt the nonblocking producer. However, there is no logic
      to trigger it again (see `publisher_worker` in `publisher.cc`). On a bigger
      picture, this nonblocking mode mimics what the publisher does internally, so
      it serves no purpose from a benchmarking perspective.

    - Remove 'use-zeek-batches' mode. This mode caused the benchmark to use the
      function `sendZeekBatch` for generating events. However, the implementation
      was identical to sendBrokerBatch (the default). Consequently, this mode was a
      fancy no-op.

1.1.2-49 | 2019-05-30 21:32:58 -0700

  * Improve shutdown behavior (Jon Siwek, Corelight)

    Sending the "kill" exit reason to CAF actors seems to more reliably
    avoid deadlock/hang issues on shutting down, likely due to it having
    more explicit logic to shut down streams.

1.1.2-48 | 2019-05-28 17:39:41 -0700

  * Fix subscriber_base::get(n, timeout) congestion tracking (Jon Siwek, Corelight)

    This could call became_not_full() in cases where the underlying queue
    size did not actually transition to below the congestion limit.

  * Fix race in subscriber_base::poll() leading to vector realloc (Jon Siwek, Corelight)

    The value used to reserve the initial vector capacity may
    be underestimated due to unlocking a mutex between the call
    to buffer_size() and consume(), leading to unnecessary vector
    re-allocation.

  * Improve broker::bro::Message API to help avoid copies (Jon Siwek, Corelight)

  * Fix flare_actor always reporting readiness (Jon Siwek, Corelight)

    Since mailbox elements get taken via receive(), not dequeue(),
    the flare which signalled readiness never got extinguished.

  * Add broker::store::proxy::receive(n) (Jon Siwek, Corelight)

    For receiving N data store responses at a time.

1.1.2-40 | 2019-05-23 17:57:57 -0700

  * GH-43: use Python tuples to represent Broker vectors (Jon Siwek, Corelight)

    Opposed to previously mapping vectors to Python lists.

    This is needed in order to represent tables indexed by vectors: tables
    are mapped to dictionaries, dictionaries require immutable indices,
    and a tuple is immutable whereas a list is mutable.
