Compiling sip-router with ser modules

by Jan Janak

Hello Few days ago Andrei setup another repository called ser_modules on git.sip-router.org, see http://git.sip-router.org/cgi-bin/gitweb.cgi?p=ser_modules;a=summary This is a repository which contains all SER modules except tm. The repository is synchronized with cvs and receives commits from cvs on 'cvs-head' branch. I just created another branch called 'updated' in the repository and commited updates to all the modules (created mostly with ser-to-sh script) to make them compile with the sip-router core. In other words, we just reached another important milestone. We are now able to compile all (well, almost) SER modules with the sip-router core and thus we are almost ready to replace the core of ser with the new and merged sip-router core and start using/testing it. You can try to compile and use it yourself: 1) git clone git://git.sip-router.org/sip-router 2) git remote add ser_modules git://git.sip-router.org/ser_modules 3) git fetch ser_modules 4) git merge ser_modules/updated 5) make config mode=debug exclude_modules="mysql postgres dbtext jabber oracle flatstore lcr ldap osp" 6) make all And if everything goes well, you should have the sip-router core and all ser modules compiled and ready to use in your working directory.

commit mail limit changes

by Andrei Pelinescu-Onciul

I've changed the commit limit for separate mail messages vs. one big mail containing all the commits. Now if you "push" more then 15 commits, only one message will be sent to the mailing list (containing all the commits). If you "push" less then 15, then for each commit a separate mail message will be sent. The previous limit was 100 (which IMHO produced too many separate messages when kamailio or ser modules were merged). Andrei

LOG(L_DBG, FMT, ARGS...) and DBG(FMT, ARGS...) prints always the same message) - changed the format of log messages produced by the macros to include the log level, module name, filename, line (if applicable) - added new, internal LOG_(LEVEL, PREFIX, FORMAT, ARGS...) macro - removed DPrint() and DEBUG() macros, L_DEFAULT log level and dprint() function !!! !!! IMPORTANT! READ ME! !!! These changes (mainly the first two) require reformating of the most log messages in SER core and module source files. This step can be done automatically by running "scripts/logging/fix-logs-all" script BUT it was NOT originally performed because it would have generated too many changes in CVS which was discouraged by Andrei. Instead, the developers are expected to run it when ready.

URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=d65cdd3… Author: Bogdan Pintea <bogdan(a)iptego.com> Date: Mon Jan 5 21:26:44 2009 +0000 When building the route set of ACKs for local UACs, only the reply is now evaluated; this is insufficient, since replies to in-dialog requests normally miss the route set. The patch fixes that: evals INVITE, if this was in-dialog; otherwise, the reply (since the req. doesn't have yet complete route set). Add support for the SASI if'ace, adding the implemenation for two more TM API functions: - t_get_canceled_ident(): returns the hash coordinates (bucket/index) of the transaction the currently processed CANCEL is targeting - ack_local_uac(): allow generating the ACKs for 2xx'ed locally originated INVITEs - new headers and body can now also be appended to it. Fully closes #SER-346. URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=5137b02… Author: Bogdan Pintea <bogdan(a)iptego.com> Date: Sun Jan 4 15:34:54 2009 +0000 In case the AVP is a regexp, an allocation is required to build an AVP "ident". The patch adds the functionality to free it. Closes #SER-344. URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=eddf3e3… Author: Bogdan Pintea <bogdan(a)iptego.com> Date: Sun Jan 4 15:27:39 2009 +0000 Currently, SER matches E2E ACKs only if there is an equality between From HF in INVITE and ACK. While this is pretty safe, there are UAs that do mess small things, like display name, or some bigger ones, like URI, in generated ACK. However, matching over the full URI (or worse, HF) is not needed and was even intended for deprecation (see 1st comment of 3261#Sec. 12.2.1.1). The applied patch should boost a bit the matching flexibility - only compare the tag. Closes #SER-419. URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=713d776… Author: Bogdan Pintea <bogdan(a)iptego.com> Date: Sun Jan 4 15:02:11 2009 +0000 The calculate_routeset_length() produces an invalid result in the case dlg_t.hooks.last_route is set (and .first_route not). Applied patch fixes that (and should hopefully be a bit cleaner). Closes #SER-421. URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=0f92150… Author: Bogdan Pintea <bogdan(a)iptego.com> Date: Sun Jan 4 14:58:36 2009 +0000 'memapp' and 'append_mem_block' are now both only used in source t_msgbuilder.c. Applied patch removes the definition of both from .h.: memapp moved to .c, append_mem_block only left in .c. (Interestingly, gcc complained over different definitions, but accepted same definition twice, for same identifier.) Closes #SER-422.

Default: UDP (off). - force_rport = yes|no - global force_rport(). new script commands: - udp_mtu_try_proto(TCP|TLS|SCTP|UDP) - like udp_mtu_try_proto above but works on a per packet basis and not globally.

For such messages only the Via is changed (for example the original built for udp Record-Route is kept untouched so that subsequent messages in the dialog will use udp if smaller then udp_mtu). - udp_mtu and udp_mtu_try_proto (fallback proto) can be changed at runtime via the cfg framework (e.g. sercmd cfg.set_now_int core udp_mtu 1300; cfg.set_now_int core udp_mtu_try_proto 2 ) - force_rport can now be set globally using the config framework (e.g. sercmd cfg.set_now_int core force_rport 1 ) Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org>

Wiki adjustments

by Dmitry Semyonov

Hi all, I suggest to enable the following configuration options for the SIP-Router wiki: $conf['breadcrumbs'] = 7; //how many recent visited pages to show $conf['rss_content'] = 'diff'; The former one adds 'Trace:' line near 'You are here:' one with links to recently visited pages. The latter one makes RSS feeds more useful (IMHO) -- they start showing what was actually changed. -- ...Bye..Dmitry.
