Module: sip-router Branch: master Commit: f44534cbe841046079e176512b04a6b9c5a68bdc URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=f44534c… Author: Timo Reimann <timo.reimann(a)1und1.de> Committer: Timo Reimann <timo.reimann(a)1und1.de> Date: Thu Aug 25 15:17:48 2011 +0200 modules_k/dialog: Simplify and refactor parts of reference counter handling. - Remove special handling for dialogs in the "deleted" state to allow accessing such dialogs (e.g., from the configuration script). Besides making the code easier to understand, this also fixes a bug where the reference counter would be decremented after detecting a spiral (dlg_handlers.c) even though get_dlg() does not increment it for "deleted" dialogs. - Adapt interfaces for lookup_dlg() and get_dlg() accordingly, i.e., remove "del" parameter and update in-code documentation. - Replace direct increments on a dialog structure's ref variable by calls to ref_dlg_unsafe(). - Move {un}ref_dlg_unsafe() definitions towards the head of the file to make declaration available earlier. - Improve store_dlg_in_tm(): * Return and evaluate result code. * Replace second register call by passing unreference_dialog() as release function to the first register call. - Document various places in the code dealing with reference counting. --- modules_k/dialog/dialog.c | 5 +- modules_k/dialog/dlg_handlers.c | 92 +++++++------------------ modules_k/dialog/dlg_hash.c | 139 +++++++++++++++--------------------- modules_k/dialog/dlg_hash.h | 13 ++-- modules_k/dialog/dlg_profile.c | 3 + modules_k/dialog/dlg_req_within.c | 2 +- 6 files changed, 97 insertions(+), 157 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=f44…
