{s.escape.param} transformation
by Camille Oudot 25 Nov '13

25 Nov '13

Hi, I've noticed that {s.escape.param} doesn't change "@" into "%40", and yet RFC3261 specifies pvalue as pvalue = 1*paramchar paramchar = param-unreserved / unreserved / escaped param-unreserved = "[" / "]" / "/" / ":" / "&" / "+" / "$" with: unreserved = alphanum / mark mark = "-" / "_" / "." / "!" / "~" / "*" / "'" / "(" / ")" escaped = "%" HEXDIG HEXDIG I've committed a patch in coudot/escape-param branch to fix the escape function. Several unreserved characters were escaped, and some reserved ones weren't. Regards -- Camille

ndb_cassandra - New module proposal
by Luis Martin Gil 24 Nov '13

24 Nov '13

Hello, I developed a module for Kamailio SIP project. I would like Kamailio’s community to consider this work to be included in the next versions of the project. The module is called ’ndb_cassandra’, it is a non-driver db module to write and retrieve information using Apache Cassandra. It depends on thrift version 0.7.0. You can check the source code here, https://github.com/luismartingil/ndb_cassandra I would like to contribute back to Kamailio project and I think this module could be very useful. Please let me know the viability of this add-on. Thanks, Luis Martin Gil

[tracker] Comment added: Out of memory when a request is sent to itself
by sip-router 22 Nov '13

22 Nov '13

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#372 - Out of memory when a request is sent to itself User who did this - Konstantin (Konstantin) ---------- We investigated this issue in the context of the bigger problem. We use several custom modules and we met an issue which causes Kamailio server crash. In all cases we can see that the shared memory is corrupted somehow. For example, //Program terminated with signal 11, Segmentation fault. #0 0x08176264 in fm_malloc () (gdb) bt #0 0x08176264 in fm_malloc () #1 0x001a43e2 in shm_malloc (_dom=0x390cdf30, _aor=0x1b9aa4, _contact=0xbfc49408, _ci=0x1b9b20) at ../../mem/shm_mem.h:256 #2 shm_str_dup (_dom=0x390cdf30, _aor=0x1b9aa4, _contact=0xbfc49408, _ci=0x1b9b20) at ../../ut.h:700 #3 new_ucontact (_dom=0x390cdf30, _aor=0x1b9aa4, _contact=0xbfc49408, _ci=0x1b9b20) at ucontact.c:206 #4 0x001b2cd6 in mem_insert_ucontact (_r=0x1b9aa0, _c=0xbfc49408, _ci=0x1b9b20) at urecord.//c:156 Could you recommend how to analyze this problem or tools how to analyze core dumps to identify the place where the shared memory was corrupted? May be there is a way or tool to investigate the shared memory content and its integrity to find out the place where control structures were broken? Thank you in advance. ---------- More information can be found at the following URL: https://sip-router.org/tracker/index.php?do=details&task_id=372#comment1179 You are receiving this message because you have requested it from the Flyspray bugtracking system.
