Module: sip-router Branch: master Commit: 6d7e23db563b7ba70701e21928def9c228c30520 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=6d7e23d… Author: Peter Dunkley <peter.dunkley(a)crocodile-rcs.com> Committer: Peter Dunkley <peter.dunkley(a)crocodile-rcs.com> Date: Mon Mar 19 16:05:56 2012 +0000 modules_k/rls: RLS DB-only mode performance improvements - When the RLS DB-only mode was implemented it was designed to do (as close as possible) exactly what the hash-table mode did in the same way the hash-table mode did it. This means lots of hash-table lookups (which are fast) result in lots of DB selects (which are slow). It also means where an entry is found in the hash-table and modified in place, in DB mode a select must be done and then an update. A lot of these DB transactions are not strictly necessary, and often fields were retrieved or updated in the DB even when they hadn't changed. - This change refactors the DB-only code (in rls_db.c) and re-orders the functional code in other files to make the DB operations as simple as possible and as few as few as possible. --- modules_k/rls/notify.c | 6 +- modules_k/rls/resource_notify.c | 34 +- modules_k/rls/rls.h | 17 +- modules_k/rls/rls_db.c | 994 ++++++++++++++------------------------- modules_k/rls/subscribe.c | 149 ++++--- 5 files changed, 459 insertions(+), 741 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=6d7…
