compile only a given list of modules

Config framework error for tm module
by Nils Ohlmeier 25 May '09

25 May '09

Hello, when I try to start SER with the ser-basic.cfg it fails with the following error message: 0(13147) ERROR: <core> [cfg/cfg.c:135]: ERROR: register_cfg_def(): the specified size (152) of the config structure does not equal with the calculated size (148), check whether the variable types are correctly defined! Note: I added the size informations to this error message just a minute ago so that the error message is hopefully more meaningful. Does anybody know what is wrong here? I'm using Gentoo Linux with 64bit, maybe that is the reason for this failure?! Thanks Nils

what if ...
by Daniel-Constantin Mierla 22 May '09

22 May '09

Hello, what would be the drawback of having sip_msg being all the time in shared memory? Would pkg vs shm operations have relevant impact? From personal observations, most of the requests (over 95%) end in TM module (to absorb retransmission or to forward) where the sip_msg s moved to shm. It would make things simpler for tm callbacks and related routes (no need to move back/forward from/to pkg/shm). Parsing will happen always once, as now cloning to shm in tm discards some parsed headers, which may be needed in failure route or callbacks. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com/
