Kamailio Random Crash Alert - 5.4.7
by Hardik Patel 12 Jul '22

12 Jul '22

Hello Team, We are using Kamailio 5.4.7 and we found there is a random crash. We have observed the core logs and we noticed it is due to some of the RPC events. We have noticed it has been crashed from the "ctl handler" process. Please find the attached crash logs and Kamailio version details are mentioned below. version: kamailio 5.4.7 (x86_64/linux) a19fe1 flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: a19fe1 compiled on 02:56:57 Feb 16 2022 with gcc 8.3.0 -- Hardik Patel

[kamailio/kamailio] presence: No autocommit+rollback if no active watchers (PR #3183)
by Alessio Garzi 12 Jul '22

12 Jul '22

#### Pre-Submission Checklist    - [x] Commit message has the format required by CONTRIBUTING guide - [ ] Commits are split per component (core, individual modules, libs, utils, ...) - [ ] Each component has a single commit (if not, squash them into one commit) - [ ] No commits to README files for modules (changes must be done to docbook files in `doc/` subfolder, the README file is autogenerated) #### Type Of Change - [x] Small bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds new functionality) - [ ] Breaking change (fix or feature that would change existing functionality) #### Checklist:  - [ ] PR should be backported to stable branches - [x] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description This is a small performance improvement, the goal is to avoid issuing rollbacks if not necessary. On my setup, Kamailio presence executes a lot of ROLLBACKS in MariaDB since function process_dialogs() runs repeatedly. What see inside MariaDB logs is the following ``` SET autocommit=0 select `presentity_uri`,`callid`,`to_tag`,`from_tag`,`event` from `active_watchers` where `updated`=3 AND `event`<>'presence.winfo'\G ROLLBACK ``` Maybe we can improve this behaviour telling presence to do autocommit to do not execute them if the select returns zero elements?

git:master:c80cccd9: presence: No autocommit+rollback if no active watchers

Module: kamailio Branch: master Commit: c80cccd996dcc3b91d4f0f68a2de51104a16d1a5 URL: https://github.com/kamailio/kamailio/commit/c80cccd996dcc3b91d4f0f68a2de511… Author: Alessio Garzi <agarzi(a)sipwise.com> Committer: Victor Seva <linuxmaniac(a)torreviejawireless.org> Date: 2022-07-12T15:39:33+02:00 presence: No autocommit+rollback if no active watchers - In case the active_watcher query returns no elements there is a weird situation where kamailio first runs the select for active_watcher then rollbacks. This can happen a lot of times for each second since function process_dialogs() runs repeatedly. For this reason trying to avoid the rollback can result in a quite good performance boost. --- Modified: src/modules/presence/notify.c --- Diff: https://github.com/kamailio/kamailio/commit/c80cccd996dcc3b91d4f0f68a2de511… Patch: https://github.com/kamailio/kamailio/commit/c80cccd996dcc3b91d4f0f68a2de511… --- diff --git a/src/modules/presence/notify.c b/src/modules/presence/notify.c index cf52c21c22..4980dc4b0a 100644 --- a/src/modules/presence/notify.c +++ b/src/modules/presence/notify.c @@ -2867,6 +2867,7 @@ int process_dialogs(int round, int presence_winfo) str ev_sname, winfo = str_init("presence.winfo"); int now = (int)time(NULL); int updated = 0; + int no_active_watchers = 0; db_query_f query_fn = pa_dbf.query_lock ? pa_dbf.query_lock : pa_dbf.query; query_cols[n_query_cols] = &str_updated_col; @@ -2900,13 +2901,6 @@ int process_dialogs(int round, int presence_winfo) goto error; } - if(pa_dbf.start_transaction) { - if(pa_dbf.start_transaction(pa_db, pres_db_table_lock) < 0) { - LM_ERR("in start_transaction\n"); - goto error; - } - } - /* Step 1: Find active_watchers that require notification */ if(query_fn(pa_db, query_cols, query_ops, query_vals, result_cols, n_query_cols, n_result_cols, 0, &dialog_list) @@ -2920,7 +2914,17 @@ int process_dialogs(int round, int presence_winfo) } if(dialog_list->n <= 0) + { + no_active_watchers = 1; goto done; + } + + if(pa_dbf.start_transaction) { + if(pa_dbf.start_transaction(pa_db, pres_db_table_lock) < 0) { + LM_ERR("in start_transaction\n"); + goto error; + } + } /* Step 2: Update the records so they are not notified again */ if(pa_dbf.update(pa_db, query_cols, query_ops, query_vals, update_cols, @@ -3164,7 +3168,7 @@ int process_dialogs(int round, int presence_winfo) if(dialog) pa_dbf.free_result(pa_db, dialog); - if(pa_dbf.abort_transaction) { + if(no_active_watchers == 0 && pa_dbf.abort_transaction) { if(pa_dbf.abort_transaction(pa_db) < 0) LM_ERR("in abort_transaction\n"); }
