This brings to a leak on the contact DB because the contact will always have refs > 0 and no actual refs on DB. Now, as a fallback, we actually checks on DB the real number of refs of the contact. If this refs is 0, force the number of refs in the record to 0 and mark the contact for deletion. --- Modified: modules/ims_usrloc_scscf/udomain.c Modified: modules/ims_usrloc_scscf/usrloc_db.c Modified: modules/ims_usrloc_scscf/usrloc_db.h --- Diff: https://github.com/kamailio/kamailio/commit/3438dbe5e5149d23c40ba17e1c47f6b… Patch: https://github.com/kamailio/kamailio/commit/3438dbe5e5149d23c40ba17e1c47f6b…

[kamailio/kamailio] Improvements on DB handling on S-CSCF usrloc (#730)
by Federico Favaro 02 Aug '16

02 Aug '16

Some improvements on the handling of contacts on S-CSCF database, namely * Clean the contact table at startup if impu_contact table is empty * if the contact is in state DELAYED_DELETE but still has ref_count > 0 in memory, it could mean that it has not been decremented before due to a failure to get a lock. This way we are leaking a contact on the DB and in memory. When the contact is expired and in DELAYED_DELETE, we do a query to check if it is really still referenced on impu_contact table. If not, we mark contact for deletion. * Add an helper function to print the actual state of a contact instead of the index of the enum You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/730 -- Commit Summary -- * ims_usrloc_scscf: Remove all unlinked contacts * ims_usrloc_scscf: Double check contact refs on DB * ims_usrloc_scscf: Print contact state as string -- File Changes -- M modules/ims_usrloc_scscf/udomain.c (26) M modules/ims_usrloc_scscf/usrloc.h (17) M modules/ims_usrloc_scscf/usrloc_db.c (72) M modules/ims_usrloc_scscf/usrloc_db.h (2) -- Patch Links -- https://github.com/kamailio/kamailio/pull/730.patch https://github.com/kamailio/kamailio/pull/730.diff --- You are receiving this because you are subscribed to this thread.
