Release notes for current version of Sofia-SIP
|
|
==============================================
|
|
|
|
Changes since last release
|
|
--------------------------
|
|
|
|
Beside bugfixes, a server graylisting was added to nta and a few
|
|
improvements in event handling were made in nua interface.
|
|
|
|
A check-based test program was added, too.
|
|
|
|
API/ABI changes and versioning
|
|
------------------------------
|
|
|
|
New features in API are marked with Doxytag macro @NEW_1_12_8 or
|
|
@VERSION_1_12_8.
|
|
|
|
libsofia-sip-ua:
|
|
- Added nta_sip_is_internal(), nta_msg_is_internal() function in
|
|
<sofia-sip/nta.h>. Deprecating nta_is_internal_msg().
|
|
- Added su_msg_new(), su_msg_send_to() and su_msg_deinitializer() for more
|
|
robust and light-weight message passing in <sofia-sip/su_wait.h>
|
|
- Added su_home_lock(), su_home_trylock(), and su_home_unlock() in
|
|
<sofia-sip/su_alloc.h>
|
|
- Added type-neutral template macros for hash tables HTABLE2_DECLARE2(), HTABLE2_PROTOS2(),
|
|
and HTABLE2_BODIES2().
|
|
- Added sres_cache_set_srv_priority() in <sofia-resolv/sres_cache.h> and
|
|
sres_set_cached_srv_priority() <sofia-resolv/sres.h> for graylisting
|
|
SRV records for inresponsive servers.
|
|
- nua_create()/nta_agent_create()/tport_bind() now joins to multicast group
|
|
if "maddr" parameter is specified
|
|
- 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:
|
|
- No ABI/API changes, compatible with 1.12.0. Note, libsofia-sip-ua-glib
|
|
interface is not considered stable and may change in a future 1.12.x
|
|
release.

SIP Server Graylisting
|
|
----------------------
|
|
|
|
The hack contributed by Stefan Leuenberger from Netmodule changes the
|
|
priority of SRV records which are used when SIP URI is resolved.
|
|
|
|
If your domain has multiple servers, you can define separate SRV records for
|
|
them. If any of them becomes unresponsive, a SIP request sent to it times
|
|
out or gets rejected because of network error and Sofia SIP automatically
|
|
retries with another server. However, as Sofia SIP does not keep track of
|
|
failed servers with the next request it may again try first the failed
|
|
server. The graylisting repriotizes the SRV records so that the priority of
|
|
the failed server gets reduced and it won't be tried again until all other
|
|
servers have failed, too. Note that the SIP URI resolver may get confused
|
|
when using this kind of repriotizing if a single SRV record corresponds to
|
|
multiple servers or servers with multiple addresses.
|
|
|
|
You can disable the reprioritizing hack by including tag NTATAG_GREYLIST(0)
|
|
with nua_create(), nua_set_params(), nta_agent_create() or
|
|
nta_agent_set_params().
