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..
