[sr-dev] git:master:629c1674: sync: added support for millisecond resolution sleep

Module: kamailio Branch: master Commit: 629c1674fcbbfd12310da924e8b6cd5116cd71a3 URL: https://github.com/kamailio/kamailio/commit/629c1674fcbbfd12310da924e8b6cd5… Author: Paweł Pierścionek &lt;ppierscionek(a)gmail.com&gt; Committer: Henning Westerholt &lt;henningw(a)users.noreply.github.com&gt; Date: 2019-07-28T16:28:35+02:00 sync: added support for millisecond resolution sleep - new ms_timer parameter to enable millisecond precision timer - new async_ms_route and async_ms_sleep functions with milliseconds as a param - implementation: Each async_ms_sleep adds an entry to a linked list sorted by expiry time. List is checked every ms_timer ms for expired entries. All expired entries are pushed for execution on a pool of async workers. --- Modified: src/modules/async/async_sleep.c --- Diff: https://github.com/kamailio/kamailio/commit/629c1674fcbbfd12310da924e8b6cd5… Patch: https://github.com/kamailio/kamailio/commit/629c1674fcbbfd12310da924e8b6cd5… --- diff --git a/src/modules/async/async_sleep.c b/src/modules/async/async_sleep.c index ff1da14639..0e78879483 100644 --- a/src/modules/async/async_sleep.c +++ b/src/modules/async/async_sleep.c @@ -130,7 +130,7 @@ int async_init_ms_timer_list(void) if(lock_init(&_async_ms_list->lock) == 0) { LM_ERR("cannot init lock \n"); shm_free(_async_ms_list); - _async_ms_list = 0; + _async_ms_list = NULL; return -1; } return 0; @@ -140,6 +140,8 @@ int async_destroy_ms_timer_list(void) { if (_async_ms_list) { lock_destroy(&_async_ms_list->lock); + shm_free(_async_ms_list); + _async_ms_list = NULL; } return 0; } @@ -384,19 +386,6 @@ int async_ms_sleep(sip_msg_t *msg, int milliseconds, cfg_action_t *act, str *cbn LM_ERR("callback name is too long: %.*s\n", cbname->len, cbname->s); return -1; } - dsize = sizeof(async_task_t) + sizeof(async_task_param_t) + sizeof(async_ms_item_t); - - at = (async_task_t *)shm_malloc(dsize); - if(at == NULL) { - LM_ERR("no more shm memory\n"); - return -1; - } - memset(at, 0, dsize); - at->param = (char *)at + sizeof(async_task_t); - atp = (async_task_param_t *)at->param; - ai = (async_ms_item_t *) ((char *)at + sizeof(async_task_t) + sizeof(async_task_param_t)); - ai->at = at; - if(cbname && cbname->len>=ASYNC_CBNAME_SIZE-1) { LM_ERR("callback name is too long: %.*s\n", cbname->len, cbname->s); return -1; @@ -417,9 +406,22 @@ int async_ms_sleep(sip_msg_t *msg, int milliseconds, cfg_action_t *act, str *cbn if(tmb.t_suspend(msg, &tindex, &tlabel) < 0) { LM_ERR("failed to suspend the processing\n"); - shm_free(ai); return -1; } + + dsize = sizeof(async_task_t) + sizeof(async_task_param_t) + sizeof(async_ms_item_t); + + at = (async_task_t *)shm_malloc(dsize); + if(at == NULL) { + LM_ERR("no more shm memory\n"); + return -1; + } + memset(at, 0, dsize); + at->param = (char *)at + sizeof(async_task_t); + atp = (async_task_param_t *)at->param; + ai = (async_ms_item_t *) ((char *)at + sizeof(async_task_t) + sizeof(async_task_param_t)); + ai->at = at; + at->exec = async_exec_task; at->param = atp; atp->ract = act;
