Segfault on /quit

[jmdaemon]

1. Launch weechat
2. Either, configure weechat matrix with invalid credentials
3. Check for error "LoginError: 403 Invalid Password"
4. Type /quit
5. Segfault

There's also another way that involves doing something similar

1. Launch weechat
2. Configure no credentials and prompt for SSO instead
3. Check for "matrix: The server requested a single sign-on ..." message
4. Type /quit
5. Segfault

I'm also experiencing this on every /quit. It happens both when starting weechat normally, as well as with a running weechat-headless.

For me, the steps to reproduce are:

1. With the matrix plugin set to load on startup AND with server.matrix_org.autoconnect set to on
2. Open weechat
3. Type /quit and hit <ENTER>
4. /quitzsh: segmentation fault (core dumped) weechat

Setting server.matrix_org.autoconnect to off fixes this issue, but as soon as you connect to the matrix server, quitting weechat produces a segmentation fault.

weechat freezes every time I type /quit. It doesn't segfault, but I do have to kill -KILL it every time I exit it. It's terrible.

[grtcdr]

The freezes have happened to me as well, but the segfaults are more frequent. I've had to uninstall the plugin because it was becoming unusable.

What alternatives are there?

[ewtoombs]

You mean besides element? That's what I have had to resort to for now.

It's probably this issue

[FIGBERT]

Freezes indefinitely on quit for me as well. WeChat v3.4.1, Python v3.10.2, macOS

[LorenzoBianconi]

@poljar are you still maintain this plugin? Do you suggest to switch to rust implementation?

[poljar]

The Rust implementation does not have feature parity with the Python one, sadly I'm not sure when I'll get the chance to return to this.

[grtcdr]

@poljar I think this issue should be mentioned in the README, so that future users are aware of them instead of being surprised by them.

[scresante]

weechat-matrix.py is the only thing I have in ~/.local/share/weechat/python/autoload
I get a hang on /quit with weechat-matrix.py loaded and connected
I get a hang on /plugin unload python
Turning off matrix_org.autoconnect, with the .py in still in the autoload dir allows a successful /quit

Using python 3.10.6 on arch.

This might be related to weechat/weechat#1519

Since I rarely use matrix (although I do appreciate its features) I will probably just keep it turned off and use a different client.

I have not seen segfaults on /quit. My setup is a little different:

I'm using Debian Buster, with all the following, and the python dependencies, installed in a separate user account:

• weechat compiled from git, version 3.6 e5a159c74f8c71483129abd013b77f0f7a9ca216
• olm compiled fromgit, version 3.2.9 0dde38bd4f49ad1c690e60041703ff1cddd4c8de
• weechat-matrix from git, c2d2a52
• python dependencies installed by the above

python-ldap 3.1.0

I had no time to look into it yet but I think the issue is due to python3. I am running python 3.10.6 (fedora 36) and I can reproduce the issue

[ilf]

I can also confirm this bug. weechat 3.8 hangs on /script unload matrix or quit.

Even more annoying, weechat doesn't safe settings like "weechat.look.save_config_on_exit", because it doesn't exit cleanly.

The weechat issue has already been posted: weechat/weechat#1519

@poljar: Is there anything weechat-matrix can do about this? If so: what do you need?
