[kamailio/kamailio] topos module does not update topos_d timestamp at re-INVITE (#2024)

by Henning Westerholt

The topos module fails to update the dialog data in the topos_d table after the processing of re-INVITEs. I have setup a call at 11:55, and triggered a re-INVITE at 12:08. The respective topos_d table entry is not updated. This causes the entry to expire after topos dialog_timeout value. I would expect that the timestamp of the call in the topos_d table is updated. Is this assumption correct? If the current behavior is expected, it should documented in the module README. No error messages from topos module in kamailio.log. Output from tables: ``` MariaDB [kamailio]> select id, rectime, s_method, a_callid from topos_t; select id, rectime, s_method, a_callid from topos_d; +-----+---------------------+----------+----------------------------------+ | id | rectime | s_method | a_callid | +-----+---------------------+----------+----------------------------------+ | 305 | 2019-08-04 12:08:12 | INVITE | q0Jeh9g49GeYdJXqcjCo-G0CW4dQ0iav | | 306 | 2019-08-04 12:08:12 | ACK | q0Jeh9g49GeYdJXqcjCo-G0CW4dQ0iav | | 307 | 2019-08-04 12:08:14 | INVITE | q0Jeh9g49GeYdJXqcjCo-G0CW4dQ0iav | | 308 | 2019-08-04 12:08:14 | ACK | q0Jeh9g49GeYdJXqcjCo-G0CW4dQ0iav | +-----+---------------------+----------+----------------------------------+ +-----+---------------------+----------+----------------------------------+ | id | rectime | s_method | a_callid | +-----+---------------------+----------+----------------------------------+ | 156 | 2019-08-04 11:55:22 | INVITE | q0Jeh9g49GeYdJXqcjCo-G0CW4dQ0iav | +-----+---------------------+----------+----------------------------------+ ``` -- You are receiving this because you are subscribed to this thread.

Re: [sr-dev] [SR-Users] Dispatcher round-robin problems in 5.2

by Henning Westerholt

Hi Alex, there have been many changes to the modules between 5.1 and 5.2. I just looked a bit to the code of dispatch.c and also the commits. I noticed something in commit 3933a64c464acfb285e - there was a block related to round-robin before which got removed in this refactoring (if I analyzed it correctly): - /* if alg is round-robin then update the shortcut to next to be used */ - if(alg == DS_ALG_ROUNDROBIN) - idx->last = (hash + 1) % idx->nr; It could be simple added back, because of the changed logic, though.

[kamailio/kamailio] core: Fix the cfg framework variable input type default (#2022)

by Mancaș George

#### Pre-Submission Checklist    - [x] Commit message has the format required by CONTRIBUTING guide - [x] Commits are split per component (core, individual modules, libs, utils, ...) - [x] Each component has a single commit (if not, squash them into one commit) - [x] 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 What the affected line of code really wants to achieve is: if an accepted inputs type mask is not specified then default to accepting only the actual variable type. So we must mask the var type first, then shift it by `CFG_INPUT_SHIFT`, before or-ing it with the rest. What happened before was that the entire type was shifted, and that included var type, input type and flags. What we end up with is some additional higher bits set (for flags). I actually discovered this while adding an additional flag that was meant to mark variables as private, only accessible through an internal API (not available to modules such as cfg_rpc).
