[LCR] Bug in load_gws(pvar) in Kamailio 1.5

by Iñaki Baz Castillo

Hi, I set "from_uri = out" in "lcr" table. Then I call: $var(destination) = "out"; load_gws("$var(destination)") or: $var(destination) = "no-out"; load_gws("$var(destination)") or: $var(destination) = "no-out-lalala"; load_gws("$var(destination)") In any case LCR matches the rules of "lcr" table with "from_uri = out" !!! If I set: $var(destination) = "nooooo"; load_gws("$var(destination)") then rules are not loaded (as expected). So it seems that load_gws(pvar) does an internal match like: if table_from_uri =~ /PVAR_VALUE/ IMHO it should do: if table_from_uri =~ /^PVAR_VALUE$/ -- Iñaki Baz Castillo <ibc(a)aliax.net>

[tracker] Task closed: speex, sems and mi_datagram with quotes

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task is now closed: FS#7 - speex, sems and mi_datagram with quotes User who did this - Daniel-Constantin Mierla (miconda) Reason for closing: Not a bug Additional comments about closing: The MI command coming from sems must escape inner double-quotes. Otherwise it breaks MI cmd format, where multiline parameters are enclosed in double-quotes and followed by new line. FYI, last sems supports SIP natively, MI communication is pretty much obsolete.

Patches to get proper status code in daemonize mode

by Iñaki Baz Castillo

Hi, I've submitted some patches to the SR tracker in order to improve something that I consider buggy (and for sure it is): http://sip-router.org/tracker/index.php?do=details&task_id=66 As explained in the tracker, in daemonize mode kamailio doesn't return the proper status code. If for example the listen address is not local or a DB connection uses an invalid password, then the command "kamailio" would return 0 (OK) anyway (even if it fails to start). This occurs because all those checking (socket, DB connections...) are performed *after* invoking daemonize() so the parent process (which could be invoked by "/etc/init.d/kamailio start") returns 0 knowing nothing about those errors. In fact the only checking done before daemonizing is the config file parsing. The patches I've upload to the tracker improve/fix it by doing the following: - 'daemonize()' function doesn't exit the parent process, instead the parent process gets blocked in 'main()' function reading a pipe. - When the main process initializes the modules, sockets and so, it writes into the pipe so the parent process exists with 0. - If the main process fails to start then the pipe write fd is closed with no more processes writting into it so the parent process detects it and exists with -1 error. I've checked it and works ok. You can try to set a wrong MySQL password or a wrong listen address and run kamailio in daemonize mode. Check the exit status so you will get error code rather than 0 (as occurs without these changes). This is strongly required when working with HeartBeat (and any other software managing daemons) because HeartBeat relies on the init script returned status codes. Imagine for example that a MySQL password is changed. For any reason HeartBeat decides to change the service to nodo-2. This is what would happen without the proposed changes: - HeartBeat invokes "/etc/init.d/kamailio start". - It returns 0 even if it fails to start due to MySQL password. - HeartBeat invokes periodically "/etc/init.d/kamailio monitor" (similar to "status") which would return 1 (it's not running). - Then HeartBeat tries to start it again. And of course, it receives 0 again. - Loop... This is, a init script return codes are *important* and current SR/Kamailio doesn't do it well as it fails in daemonize mode. I will use these patches in production very soon as I'm building some platforms of Kamailio+HeartBeat and this is really required. If somebody could review than patches it should be great.
