Roadmap to the next major release - v5.6.0

by Daniel-Constantin Mierla

Hello, it is the time to plan a bit the road to the next major release, to be versioned 5.6.0. The 5.5.0 was release about one year ago, therefore it is time to set the milestones for getting 5.6.0 out. I would propose to freeze the development on Thursday, April 14, 2020, test till mid of May or so, then release v5.6.0. There is a lot of development to existing components and a couple of new modules. If anyone wants a different time line towards 5.6.0, let's discuss and choose the one that suits most of the developers. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

The recursive lock of tm module is not safe?

by progrom

Hi： See lock_hash in h_table.c: Flowing lines of code do not guarantee atomicity and I think it is not safe: -      atomic_get(&_tm_table->entries[i].locker_pid) != mypid -      lock(&_tm_table->entries[i].mutex) -      atomic_set(&_tm_table->entries[i].locker_pid, mypid) Would you mind solving my confusion?

[kamailio/kamailio] dead lock of dialog module (Issue #3084)

by progromm

### Description See `internal_get_dlg`: ```C static inline struct dlg_cell* internal_get_dlg(unsigned int h_entry, str* callid, str* ftag, str* ttag, unsigned int* dir, int mode) { struct dlg_cell* dlg; struct dlg_entry* d_entry; d_entry = &(d_table->entries[h_entry]); dlg_lock(d_table, d_entry); for (dlg = d_entry->first ; dlg ; dlg = dlg->next) { /* Check callid / fromtag / totag */ if (match_dialog(dlg, callid, ftag, ttag, dir) == 1) { ref_dlg_unsafe(dlg, 1); if (likely(mode == 0)) { dlg_unlock(d_table, d_entry); } LM_DBG("dialog callid='%.*s' found on entry %u, dir=%d\n", callid->len, callid->s, h_entry, *dir); return dlg; } } if (likely(mode == 0)) { dlg_unlock(d_table, d_entry); } LM_DBG("no dialog callid='%.*s' found\n", callid->len, callid->s); return 0; } ``` Should judge whether `mode` is 0 before `dlg_lock` . -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3084 You are receiving this because you are subscribed to this thread.
