## Vortex Library 1.0.3 ##
## "Hands open release" ##
Advanced Software Production Line is proud to announce the Vortex
Library 1.0.3 "Hands open release" availability: an open source "BEEP
Core" protocol implementation written in C, mapped onto TCP/IP.
Vortex Library has been developed inside the Af-Arch project as its
data transport layer.
Vortex Library is a stable and robust application protocol
development toolkit. Currently it is running under Microsoft Windows
and GNU/Linux platforms.

The release in short
Finally, vortex library no longer depends on Glib and GThread. It
now includes its own abstraction layer for the threading API
(supporting POSIX and win32 backend).
Implemented a new general purpose filtering mechanism (Profile
Masks) which allows to configure and control which profiles can be
selected. This have been used by Turbulence to implement a powerful
administrative configuration which allows to mix, select, and filter
profiles according to serverName parameter, peer remote address,
profiles that are already initiated, etc.
The xml-rpc-gen tool is now fully tested, being considered as a
Updated Vortex I/O waiting API to support poll(2) and epoll(2)
system calls when available. The new added API allows to select each
mechanism at run-time even during transmission!
Implemented a fully working TUNNEL profile, allowing every BEEP
profile implemented on top of Vortex to be TUNNELed through a BEEP
proxy at run-time without any modification. Turbulence uses this
TUNNEL implementation to provide a general TUNNEL BEEP server, with
an administrative configuration.
Lot of work have been done to increase the Vortex Library run-time
performance, reducing its memory consumption. Client regression test
used at 1.0.2 was completed with 14.244 seconds, while the similar
test (with more checkings added) is completed in 5.832 seconds.
Thomas Unterleitner (reported and fixed wrong signal configuration
at the windows platform).
Milton Yates (fixed warnings at vortex main header, fixed missing
parameter received in the validation resource function for the
Martin Huter (provided really useful patches to integrate poll(2)
and epoll(2) into vortex).
Changes since 1.0.2
* [fix] Added #ifdef macros to avoid exposing signal configuration
while compiling vortex.c under windows (Reported and fixed by Thomas
* [fix] Fixed some warnings caused by header definitions at vortex
module. (Reported and fixed by Milton Yates).
* [fix] Fixed a missing parameter received in the validation resource
for the xml-rpc implementation (Reported and fixed by Milton Yates).
* [new] Added new module to implement a portable threading API,
supporting initially POSIX and windows API. The new API includes
basic support to create threads, support for mutex and support for
conditional vars. Replaced all calls to previous api g_mutex_*,
g_thread_* and g_cond*. Checked that the result properly executes
the regression test. API added:
- VortexThread (type)
- VortexThreadConf (enum)
- VortexMutex (type)
- VortexCond (type)
* [fix] Replaced all calls to the g_static_mutex* api with new API
* [fix] Removed vortex semaphore modules. It is no longer required.
* [new] Committing initial headers to implement a message queue, to
current implementation based on GAsyncQueue.
* [new] Implemented a replacement for GAsyncQueue, with the API
- VortexAsyncQueue (type)
* [fix] replace calls to previous message queue API with the new one
provided: VortexAsyncQueue. Replaced all calls to previous logging
facilities, using new one provided by vortex_log. Ensured all
regression test work properly.
* [fix] Updated regression test to conform with the new changes
introduced. Removed pkg-config reference to gthread-2.0
module. Removed all gthread initialization code.
* [fix] Updated vortex hash handling provided by vortex connection and
vortex channel modules, to fully use services provided by axlHash
(removed previous code that was adding support to configure a
key_destroy and a func_destroy per item, which is supported by axl
* [new] Added new API to replace an item into the VortexHash
configuring the key and value destroy function. Added also a
function to get and clear a data from the hash atomically. API
* [fix] Making vortex_channel_get_piggyback to use
vortex_hash_lookup_and_clear to avoid possible race condition.
* [fix] Reimplemented vortex queue module internals to use axlList
rather than GQueue. Checked library status against regression test.
* [new] Added support to implement a profile filtering mechanism that
allows to install user space handlers which are executed by vortex
to check if a profile could be used (in many contexts, for example
while producing the greetings reply, or returning remote side
profiles supported). Updated vortex internals, sasl and tls
implementation to use this new feature. Nice! API added:
- VortexProfileMaskFunc (handler)
* [fix] fixed wrong conditional wait at vortex_async_queue_timedpop.
* [fix] Fixed race condition causing channel module to dealloc an
string which is later used while closing the channel 0 acting as a
* [fix] committing missing channel module headers for previous fix.
* [new] Updated vortex-regression-client to check vortex on close
connection notification functions.
* [fix] Simplified internal implementation for the full on close
connection notification, to use axlList rather than GList, storing the
handler and the data associated inside a single node.
* [fix] Reimplemented channel closing functions, at the connection
close to replace GList previous implementation with axlList. Used
destroy notification functions from axlList to improve channel
* [fix] Fixed bug and memory leak at the channel extended start
handling, causing to not use the error reply produced by the profile
implantation, loosing that content and the memory reference.
* [fix] Fixed memory leak at the sasl implementation, causing to
double-allocate the password returned for the CRAM-MD5 and the
* [fix] Updated implementation for vortex_profiles_get_actual_list, to
use axlList rather than GList.
* [fix] Fixed documentation references, and removed VortexSemaphore
* [fix] several fixings to make the new threading layer to properly
work on windows.
* [fix] Updating version and configure.ac files.
* [fix] Updated compilation files for windows: removed reference to
vortex semaphore module, added vortex thread.
* [fix] Fixed race condition at __vortex_connection_set_not_connected.
* [fix] xml-rpc-gen: replaced getline implementation with a portable
one, that is available on windows and linux. Updated tool headers to
include some definitions to avoid to make the tool available on
* [fix] Included initial support to the poll interface, and reworked
race condition fixed previously on windows which was causing
problems on linux.
* [fix] Committing update to the libvortex.def to remove function which
are not available on windows and updated Makefile.am to produce a
proper .def file.
* [new] Added support to vortex library to change the I/O wait API at
runtime. Integrated into regression tests, and now vortex tests
are changed against all available I/O API installed. GREAT!! API
* [new] Added support to use poll(2) system call to perform I/O
waiting, which is selectable at any time. (Martin Huter reported and
provided really useful patches to integrate poll(2) into
* [new] Added new API to allow setting and getting run time
configuration used by the library. Implemented initial support to
get current listen backlog and socket number limit
configuration. Making vortex listener module to use this value while
allocating new listeners. API added:
- VORTEX_LISTENER_BACKLOG, VORTEX_SOFT_SOCK_LIMIT,
* [fix] Removed all references to G_OS_UNIX and G_OS_WIN32, replaced
by its similar macros found in axl.
* [fix] Fixed bug which was causing to get a listener connection
locked into the situation where no more sockets could be allocated
(making accept call to fail) due to system limits reached, but at
the same time the listener completed connection queue (backlog) is
full and always reporting for pending events to be processed.
* [fix] Finished initial implementation to configure vortex_conf_set.
* [new] Added complete support for the epoll(2) interface, fully
tested and integrated into the regression test (Thanks for Martin
Huter for providing useful information and patches to integrate
poll and epoll).
* [new] Making vortex compile configuration to detect and check the
better I/O waiting interface, to make it the default one. Now, the
library supports select(2), poll(2) and epoll(2).
* [fix] Fixed a bug inside the select(2) I/O implementation which was
causing to overrun the file set buffer, leading to weird bugs.
* [fix] Making vortex master listener connection to also have data
* [fix] Making vortex_connection_is_ok to activate free on fail
feature in all cases.
* [new] Updated all vortex io interface to provide support for
automatic dispatch, allowing to improve performance one those
mechanism that can implement it. For now, poll(2) and epoll(2)
implements it. API added:
* [new] Added new function to check queue items at a vortex async
queue. API added:
* [fix] Making vortex reader to take check result provided by
vortex_io_waiting_invoke_add_to_fd_group to drop the connection not
* [fix] Making vortex reader to check for automatic dispatch for the
current I/O mechanism selected, and fallback into the default check
based on "is-set".
* [fix] Making vortex_io_waiting_use to be callable before
* [fix] Removed G_GINT64_CONSTANT declaration for MAX_SEQ_MOD.
* [fix] Fixing documentation error and updated windows definition
* [fix] Committing updates to include checkings to activate I/O support
from vortex. Updated version files and latest change notification.
* [fix] Updated documentation to include references to the new I/O
* [fix] Fixed bug at the SASL server side layer which was causing to
not allow renegotiate the sasl auth once a previous failed one was
* [fix] Making channel 0 start message handling to check if the
profile requested is filtered for the connection that is holding the
* [fix] Updating autoconf files to check and properly detect threading
* [fix] Improved epoll checks to ensure it is really supported (not
only by checking headers).
* [fix] Fixed wrong declaration for pthread flags.
* [fix] Fixed and updated vortex documentation.
* [new] Added initial files and modifications to support the TUNNEL
profile. Updated vortex handlers and types to include some initial
definitions. Added new module vortex tunnel. API added:
- VortexTunnelSettings (type)
- VortexTunnelItem (TUNNEL_END_CONF, TUNNEL_FQDN, TUNNEL_PORT
TUNNEL_IP4, TUNNEL_IP6, TUNNEL_SRV,
* [fix] Fixed bug introduced at the xml-rpc-gen tool due to its port
to windows while reading lines from the user command line.
* [new] Finished TUNNEL profile implementation for client, server and
middle hop. Great!!!
* [fix] Updated several tests to check the TUNNEL profile including
regression tests and the client connections test.
* [fix] Making vortex_cond_wait and vortex_cond_timedwait to return a
status value to report any error found. Used this update to ensure
the wait-for-pending-replies feature implemented at the BEEP close
to limit that operation if the session is closed not properly.
* [fix] Fixed wrong SEQ frame handler which was reporting to update
the receiving window without waiting to be used half of the window
* [fix] Making vortex log handler to check only one time for the
environment variable, reducing the overhead due to calling getenv.
* [fix] Updated vortex TLS implementation to base is tuning reset on
the preread handler rather than the on close connection.
* [new] Added new functions to the TUNNEL api already implemented to
check if TUNNEL profile is available, to produce proxy settings from
a xml content and to make a BEEP peer to accept TUNNEL incoming
request and a function to set a handler which is executed to
resolver particular TUNNEL settings such as "endpoint", "profile"
* [fix] Implemented an xml document cache for greetings parsing which
is shows an stable patern, allowing to reduce the greetings parsing
overhead from 35.17% to 10.45% (callgrind results).
* [fix] Implemented a hostname resolution cache on top of
gethostbyname, solving its possible reentrant problems on some
platform and speeding up host name resolution previously done.
* [fix] Making channel close reply validation to try doing a fast
validation by checking the common string replied rather than using
axl services to parse a minimal string.
* [fix] Making vortex channel frame received for channel 0 to use a
fast check (based on inspecting payload headers) to detect the kind
of message avoiding to move the payload into the xml level.
* [fix] Removed frame received on channel 0 validation which is
performed later by each handler (start, close, ok, error).
* [fix] Fixed client connections (was not properly configuring proxy).
* [fix] Making vortex tunnel ok reply handling to use fast string
checking before going into translating the reply into a xml doc.
* [fix] Removed GThreadFunc definitions replaced with
* [fix] Making vortex tunnel listener implementation to check for
"<tunnel />" profile content, to quickly detect end point tunnel
* [fix] Making vortex channel start reply handling to use a reply
cache allowing to greatly improve channel creation.
* [fix] Making some work at the vortex tunnel start request handling
to reuse references, avoiding double memory allocation patterns.
* [fix] Updated vortex_greetings_send function to use an internal list
from the vortex profiles rather than reallocating a new one for each
greetings done, and removed all allocation code to build the
greetings message, replaced by a memcpy/strlen construction.
Reduced function overhead from 21.49% (total run-time cost,
according to callgrind results using regression tests) to
* [new] Making vortex_listener_set_on_connection_accepted to support
any number of handlers to be executed on connection accepted.
* [new] Making vortex-client to allow requesting to create new
channels using profiles even not adviced by the listener peer.
* [fix] updated profile mask support to allow notify the rest of
parameters that are involved in the channel creation.
* [new] Added a new function to get the first channel found on a
connection running a profile. API added:
* [fix] Making vortex listener server on accept new connection event
to be triggered before the initial greetings is about to be sent.
* [new] Updated vortex hash API to allow performing foreach operations
with two user defined pointers. API added:
* [fix] fixed vortex_connection_get_channel_by_uri, using previous
* [new] Making vortex to allow creating channel that are even not
advised by the remote peer. Updated vortex conf API to allow
configuring this behavior which is allow creating any channel
requested by default. API updated:
VORTEX_CONF_ENFORCE_PROFILES_SUPPORTED (enum for vortex_conf_* API).
* [new] General internal update to finally remove glib dependency.
Checked regression tests and memory consumed. Initial results shows
* [new] Added some documentation to show how to use the TUNNEL
* [fix] general updates and fixings to make latest vortex library base
code to compile and properly run on windows. I can't write more
changes because my wife is getting annoyed!
* [fix] Removed requirement to return at least one profile in the
initial greetings. This is now an accepted case for the vortex
library: sending empty greetings. This is now used by turbulence and
its profile path, to hide profiles according to the environment
* [fix] Moving to the public header all marks used from the sasl
module to make them more available while using these marks with
turbulence "connmark" support.
* [fix] Fixed some compilation warnings at the vortex support module
and documented SASL marks that can be used by turbulence.
* [fix] Fixing bug at vortex_support_getenv_int while getting
variables not defined.
* [fix] Added an internal flag (__COMPILING_VORTEX__) to protect code
definitions that must be used while compiling vortex library, but
not used by vortex API consumers.
* [fix] Removed MAX(a,b) definition from vortex support header because
it is not strongly used, and because it is causing
collisions. Updated vortex reader to use standard ?: statement to
check for the max value.
* [fix] Updated documentation to reflect current dependencies and
* [fix] Removed glib dependency from the pkg-config file.
* [fix] Making xml-rpc-gen tool to allow including the '%' character
inside the inline source code, at the IDL definition, without
requiring to place an escaped sequence as: %%.
* [fix] Fixed bug which was causing to not properly append all content
found inside the source code inline declaration at IDL format.
* [fix] Fixed wrong source code generation for array of ints at the
* [fix] Fixed wrong source code generation for array of strings.
* [fix] Fixed wrong source code generation for an array of booleans.
* [fix] General update to the tool to accept the type "bool" as the
* [fix] Making vortex sequencer to not flag the connection as non
connected, avoiding race conditions with the vortex reader and the
user space code.
