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.
|
||||
<changes since last written in freshmeat.net "Changes:" style;
|
||||
and in less than 10 lines, written in 3rd person English, with
|
||||

|
||||
|
||||
A check-based test program was added, too.
|
||||
Bugs in blaa and foo have been fixed. The stack now supports
|
||||
use of foobar...
|
||||
|
||||
API/ABI changes and versioning
|

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.

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

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().
