Hello all,
the first Sofia-SIP release for year 2007 is now finally out! Release
notes follow:
Release notes for Sofia-SIP version 1.12.5 (2007-02-12)
=======================================================
Sofia-SIP is an open-source SIP User-Agent library, compliant with
the IETF RFC3261 specification. It can be used as a building block
for SIP client software for uses such as VoIP, IM, and many other
real-time and person-to-person communication services. The primary
target platform for Sofia-SIP is GNU/Linux. Sofia-SIP is based on a
SIP stack developed at the Nokia Research Center. Sofia-SIP is
licensed under the LGPL.
Changes since last release
--------------------------
Support for request queuing has been added to the high-level user-agent
API. Various portability improvements have been made related to Linux,
Mac OS X, Windows and Solaris ports. SIP registrations have been
modified to utilize persistent transport connections. The GObject
interface to 'nua' (nua-glib) has been dropped from the package and is
now distributed separately. Severe bugs in 'su', 'nua', 'nta', 'stun' and
'su-glib' modules have been fixed.
API/ABI changes and versioning
------------------------------
New features in API are marked with Doxytag macro @NEW_1_12_5.
Experimental features are marked with Doxytag macro @EXP_1_12_5.
libsofia-sip-ua:
- Added nua tags NUTAG_APPL_METHOD() and NUTAG_NEWSUB()
- Added nua_substate_make(), nua_substate_name()
- Added nta_incoming_create_response() function
- Added tport tags TPTAG_TOS(), TPTAG_DUMP(), TPTAG_LOG()
- Added tport predicate function tport_is_connected()
- Added authentication functions auc_info() and auc_has_authorization(),
added type msg_auth_info_t for Authentication-Info header
- Added msg_header_join_items() function
- Added sip_is_allowed() function and k_bitmap field to the
sip_allow_t structure
- Added sl_header_log implementation, updated its prototype
- Added experimental SIP headers Suppress-Notify-If-Match and
Suppress-Body-If-Match and functions related to them,
enabled with ./configure option --enable-experimental
- Added SIP header Refer-Sub and related functions
- Added <sofia-sip/sip_extra.h> include file
- Added auc_info() function (sofia-sip/auth_client.h)
- Added alternative implementations to event reactor object (su_port_t,
referenced by su_root_t) that can be changed at runtime using SU_PORT
environment variable, for instance
- Internal semantics of su_port_t reference counting have changed:
now su_port_create() has one reference, and su_root_create_with_port()
always consumes one reference
- Changed return type of bm_memmem() and bm_memcasemem() to non-const
- This release is ABI/API compatible with applications linked against
any 1.12.x release. However, applications built against this release won't
work against an older library. The ABI has been tested with the nua module
unit test (test_nua) built against original 1.12.0 release.
libsofia-sip-ua-glib:
- The 'nua-glib' module has been removed from the library and moved
to a separate package 'sofia-nua-glib'. The remaining library (su-glib)
is now considered stable and will be API/ABI compatible with later
releases in the 1.12.x series.
- ABI has been modified and applications built against 1.12.4 and earlier
releases, need to be rebuilt.
- Added su_glib_prefer_gsource() which makes glib-based su_port_t
implementation the default choice when su_root_create() is called
Contributors to this release
----------------------------
- Petteri Puolakka (patch to stun)
- Mikhail Zabaluev (patch to su-glib mainloop integration)
- Michael Jerris (patch to url parsing # in sip/sips userpart)
- Colin Whittaker (TPTAG_TOS())
- Roman Filonenko (TPTAG_LOG(), TPTAG_DUMP(),
patch to query DNS-servers with IP-Helper on win32)
- Remi Denis-Courmont (patch to network change API)
- Martti Mela (poll() emulation with select(), IPv6 and OS X fixes)
- Kai Vehmanen (persistent registrations, release management)
- Pekka Pessi (all the rest)
See the AUTHORS file in the distribution package.
Notes on new features
---------------------
- The su_root_t reactor uses different implementation (epoll, poll or select
on Linux), depending on SU_PORT environment variable.
- nua now supports request queuing, for instance, an application can send
overlapping BYE and NOTIFY requests. The stack engine takes care of
sending the new request only after the previous one has been responded.
- RFC 4488 defines the Refer-Sub header. Its datatypes, related functions and
methods declared in <sofia-sip/sip_extra.h> include file. The Refer-Sub
header structure can be accessed from sip_t structure with sip_refer_sub()
method, e.g.,
if (sip_refer_sub(sip) &&
strcasecmp("false", sip_refer_sub(sip)->rs_value) == 0) {
/* Do not create implicit subscription */
}
- Unsolicited NOTIFYs are now supported. The application can accept incoming
NOTIFYs and send NOTIFYs without existing subscription.
- Transport connections used for client registrations are now maintained
in a persistent fashion. For example a TCP connection used for
registration is not closed until client is unregisters, or the whole stack
is shut down.
- New build time options have been added: ability to build without
STUN and HTTP support. See 'docs/devel_platform_notes.txt' for some
additional notes to distributors.
Bugs fixed in this release
--------------------------
- Fixed su_from_create() returning a sip_to_t instance. Problem reported by
Ludovico Cavedon.
- Partially fixed problem #1633969 with too frequent timer
- Fixed problem in dialog matching. Problem reported by Fabio Margarido.
- Fixed #1624446 - su_wait_clone() (and nua_destroy()) blocking for ever if
the root object was created using su_glib
- Fixed #1626330 - leak in nta.c which happened if INVITE never got a final
response nor timed out.
- Fixed handle leak (pthread_*_init without pthread_*_destroy). Problem
reported by Maxim Zaikin.
- Fixed crash when nua_bye() was called while a NOTIFY client transaction
was in progress. Problem reported by Anthony Minnessale.
- Not using close() with sockets in sres.c. Problem reported by
Roman Filonenko.
- Bug in zero-padding STUN messages with a message integrity
attribute. Patch by Petteri Puolakka.
- Fixed a severe problem with timer accuracy, when sofia-sip timers
where used under glib's mainloop.
- Improved glib mainloop integration to avoid warnings about already
active mainloop context, and potentially other issue. Patch by
Mikhail Zabaluev. Closes sf.net item #1606786.
- Ignore harmless syntax errors in incoming requests/responses by default
- If a TCP connection cannot be made within SIP T4 (because of a
firewall, for instance) nta now tries to use UDP instead.
