Release note
~~~~~~~~~~~~

  Advanced Software Production Line is proud to announce Vortex
  Library 1.1.9 "Jupiter Room" release availability: an open source
  "BEEP Core" protocol implementation written in C, mapped onto
  TCP/IP.

  Vortex Library is a stable and robust application protocol
  development toolkit, with active support for Microsoft Windows and
  GNU/Linux platforms.

This release in short
~~~~~~~~~~~~~~~~~~~~~

  Several bug fixes and regression tests were added, specially for
  PULL API (which now has SASL and TLS available).
 
  Some API updates to include functions to query object ref counting
  state or if a particular vortex context is in process of finishing..

Change notifications
~~~~~~~~~~~~~~~~~~~~
  None

Thanks to..
~~~~~~~~~~~

  - Gernot Seidler (Several fixes and comments for ALIVE
    implementation).

  - Dexter (documentation advices on vortex_pull_next_event).

  - Subrahmanya (reported and provided a fix for wrong profile content
    encoding on server side and wrong handling of NUL frames when MIME
    processing is disabled).


Changes since 1.1.8
~~~~~~~~~~~~~~~~~~~

* [fix] Added ref/unref pair to sequencer foreach code to avoid
  races. Bug showed by test_01r.

* [fix] Fixed wrong reference counting handling at channel on created
  handler when a failure is found, causing the user to access to a
  connection pointer for which he has no reference owned. Making
  channel on creation code to acquire/release a reference to the
  connection during on channel created if it is found channel creation
  failed.  (Bug reported by Gernot Seidler).

* [fix] Added a note to advise that a call to vortex_event_unref is
  required after a call to vortex_pull_next_event. Note reported by
  Dexter..

* [fix] Adding some notes to pull API about event serialization..

* [fix] Adding comments to PULL API to explain that the user must not
  assume any order while pulling events from the queue..

* [fix] Minor documentation update on pull api.

* [fix] Updating debian files..

* [fix] Updated test certificate used by reg test to remove accent.

* [new] Updated vortex listener API to allow creating a BEEP listener
  without registering the object created into the vortex reader. API
  added:

   - vortex_listener_new_full2

* [fix] Making vortex_sequencer_drop_connection_messages to also check
  for connection exit status to avoid iterating over internal
  sequencer structures releasing connection pending messages.

* [fix] Updated channel added/removed notification, inside vortex
  connection module, to release and re-acquire mutex before jumping
  into user handler. Added code to get safe references to handlers
  that will be called to avoid races.

* [fix] Updated vortex internal data tracking to also record bytes
  sent. Also fixed missed tracking for bytes received at readline
  functions (BEEP header).

* [new] Updated vortex connection API to include a method that allows
  removing keys/values installed with
  vortex_connection_set_data/data_full wihtout calling registered
  destroy functions. API added:

   - vortex_connection_delete_key_data

* [new] Updated thread API to include a function that return current
  reference counting state for a VortexAsyncQueue. API added:

  - vortex_async_queue_ref_count

* [fix] Updated channel wait reply code to detect connection close
  when the synchronous wait is started.

* [new] Updated vortex API to include a function that allows checking
  if current vortex context is finishing. API added:

  - vortex_is_exiting

* [new] Updated vortex Ctx API to include a function that allows
  getting current reference counting state. Added internal check to
  avoid running dealloc operation when ref count bellow or equal to 0
  is detected. API added:
   
  - vortex_ctx_ref_count

* [fix] Fixed vortex_hash_remove which was calling to remove
  twice. ???

* [fix] Updated vortex listener on accepted handler to acquire
  references to handlers about being executed before releasing lock.

* [fix] Making vortex listener module to acquire a reference to the
  listener that created the new connection so the function
  vortex_connection_get_listener returns a valid reference.

* [fix] Updated PyVortexCtx object to support an attribute that
  returns current reference counting. API added:

  - vortex.Ctx.ref_count

* [fix] Updated PyVortexCtx module to stop firing vortex events into
  python user code when it is detected vortex is finishing.

* [fix] Moved ctx configuration before first vortex_log call inside
  __vortex_channel_release_pending_messages..

* [fix] Moved vortex ctx cleanup code to be run at vortex_exit_ctx to
  avoid circular references problems (calling that releases references
  is not run until the last vortex_ctx_unref which will never happen).
  Checked regression tests to ensure everything keeps working
  (especially pull api).

* [new] Added new function to allow uninstall ctx cleanup function
  from vortex ctx API.

* [fix] Fixed bug at pull API which was causing to not release all
  events once finished vortex context (vortex_exit_ctx). Added
  regression test to reproduce bug and check fix introduced
  (test-14-e).

* [fix] Updated vortex_profiles_invoke_start to only use global start
  handler (used by pull API) when it is found start handler and
  extended start handler is not defined (which indicates a profile
  with a particular handlers).

* [fix] Fixed wrong profile content indication on channel start
  received (was always notifying none). Added regression test to
  reproduce the bug and check the fix introduced (test-01-t).  Bug
  reported and fix provided by Subrahmanya.

* [fix] Making vortex internal reply handling to check for feeder
  reference when message size is 0 to avoid accessing null reference.
  Also updated vortex sequencer internals to detect this situation.
  Added regression test to reproduce the bug and check the fix
  introduced.

* [fix] Several updates to configure process to allow detecting site
  package installation for python modules to use this value to check
  what proposes AM_PATH_PYTHON macro, to check if it is wrong, warning
  the user to upgrade or fix its autoconf install.

* [fix] Several updates to channel create process to acquire
  internally some additional references to avoid breaking when channel
  start thread takes too long and in the middle the connection is
  closed. Added regression test to reproduce the bug and check the fix
  introduced (test_01-u).

* [fix] Making internal vortex alive trigger failure to release
  internal data only when vortex_connection_remove_on_close_full
  returns ok. Bug and fix reported by Gernot Seidler.
  
* [fix] Removed calls to __vortex_alive_free_reference when failure is
  detected inside __vortex_alive_do_check and
  __vortex_alive_create_channel as recommended by Gernot. Thanks!

* [fix] Making vortex_thread_pool_remove_event to return a boolean
  value indicating if the event was removed or not.

* [fix] Making automatic event handler removal when handler returns
  axl_true to use the internal reference instead of the list position
  to avoid removing other events in the case the event list changes
  during handler execution.

* [fix] Updated vortex regression test 00-c to allow checking support
  to remove an event handler from the handler itself..checked that
  removing fix introduced previously reproduces the bug.
  
* [fix] Updated python dir checking on configure.ac process to
  avoid guessing the directory but checking the directory detected
  by autotools..
