It always seems to occur when there are problems reaching RTPEngine in a timely fashion. This is on Kamailio 5.2.4:de9a03, which I know has long fallen off the back of the maintenance train. However, line 1386 of `t_reply.c` in `master:HEAD` shows that the code is no different now: https://github.com/kamailio/kamailio/blob/master/src/modules/tm/t_reply.c#L… Of course, it's possible that something upstream has changed so as to prevent this state. Otherwise, I suppose a null pointer safety check for `Trans->uac` is recommended. I'd be happy to submit a patch, just wasn't sure if the feeling was more that this should be resolved higher up the call stack. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3297 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Building Alpine APKs fail due to sunsetting of Python2 (Issue #3257)

by Ben Kaufman

### Description Issues building `PYTHON` module on Alpine Linux due to [sunsetting of Python2](https://www.python.org/doc/sunset-python-2/). The `python2` package (apk) has been removed from the current Alpine linux. The APKBUILD file in the current Kamailio branches includes build settings for installing the Python (python2) module. While I'm guessing it's possible to build python2 in the current Alpine container it was a conscious decision to no longer have a package for it. Given this, what is the opinion about not building this by default within the APKBUILD file? ### Troubleshooting Running `abuild -r` fails due to lack of python2 libraries. #### Reproduction Running `abuild -r` fails due to lack of python2 libraries. #### Debugging Data N/A #### Log Messages N/A #### SIP Traffic N/A ### Possible Solutions In `APKBUILD` remove references to `python2` and `python` (but not `python3`). I'll submit a pull request to do this. ### Additional Information Kamailio 5.7 * **Operating System**: Alpine Linux latest -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3257 You are receiving this because you are subscribed to this thread.
