pidgin keeps crashing #288

iv4nhoe · 2020-04-03T12:00:19Z

I'm encountering seemingly random crashes of pidgin. Here's a backtrace of one of those crashes.

I;m also getting crashes on ssl-nss, but on Windows:

Same here.

MapleStoryPSN · 2020-04-03T18:01:39Z

Can also confirm it crashes on Windows.

EionRobb · 2020-04-03T18:50:12Z

Is someone able to get a debug log from before the crash by running pidgin from the command prompt/terminal with the --debug flag?

EDIT
The log contained a few lines like this:

Additional data:
all accounts were off, only discord running; pidgin is 2.13 of https://github.com/CkNoSFeRaTU/pidgin built as ./configure --prefix=/usr --disable-perl --disable-nm --with-static-prpls=jabber,irc --enable-gnutls=no

alexolog · 2020-04-03T22:24:34Z

On Windows:

(16:09:04) discord: got frame data: {"t":null,"s":null,"op":7,"d":null}
(16:09:04) dnsquery: Performing DNS lookup for gateway.discord.gg

Then the log ends.

EionRobb · 2020-04-03T22:38:37Z

Thanks all. The t: null is an unexpected response when the connection reconnects, but regardless should be checked for so that pidgin doesn't crash. Sorry about that.

pabs3 · 2020-04-03T23:10:21Z

FTR, bug Debian#955635 was reported about this issue and it contains a pidgin patch that also prevents the crashes. I think purple-discord needs to be fixed, but pidgin needs to be more robust in the face of plugins with bugs like this, so I'm suggesting that they also send their patch upstream.

sthibaul · 2020-04-03T23:38:28Z

I have forwarded the patch to https://bitbucket.org/pidgin/main/pull-requests/679/

EionRobb · 2020-04-04T08:39:38Z

Not sure what's causing it but dec5015 should workaround it for now. https://eion.robbmob.com/libdiscord.dll has been updated to patch it too

alexolog · 2020-04-04T17:59:12Z

Still crashing with the new DLL:

EionRobb · 2020-04-05T00:04:34Z

Ok, I've wrapped all purple_ssl_read()s in 4ccc5b9 until libpurple gets the patch fix applied. There's a new dll at https://eion.robbmob.com/libdiscord.dll too

pabs3 · 2020-04-05T00:20:49Z

With the new workaround I cannot connect to discord at all.

The logs are now showing this error during the initial connection:

EionRobb · 2020-04-05T00:41:22Z

Sorry @pabs3 my bad. Latest commit should fix that

alexolog · 2020-04-05T00:58:15Z

Thank you Eion. Please let us know when a new DLL is out.

EionRobb · 2020-04-05T01:01:37Z

@alexolog it already worked on Windows, oddly. Tested it before uploading. Uploaded another dll anyway, just in case

pabs3 · 2020-04-05T01:22:05Z

Thanks, the latest commit fixes the initial connection issue. I've uploaded the latest commit to Debian. I'll update the bug if anyone reports crashes.

This was probably with the previous build. I am getting the crash on windows and linux didn't build pidgin from source on windows but here is the backtrace from finch

EionRobb · 2020-04-13T21:42:21Z

Yup. Looks like from previous build. Can you recompile and retest? The dll at https://eion.robbmob.com/libdiscord.dll will be up to date with the fix too, so you don't have to build it yourself

klikevil · 2020-04-14T05:59:36Z

I just got a crash with the one from the nightly, i'll test that one and let you know :)

klikevil · 2020-04-14T06:21:26Z

Yeah that one crashed too after about 21 minutes being connected to multiple discord servers.

iv4nhoe · 2020-04-14T06:37:37Z

Sorry @pabs3 my bad. Latest commit should fix that

I haven't experienced any crashes with db7dc79 anymore.
As far as I'm concerned this issue is fixed.

EionRobb · 2020-04-14T07:08:14Z

@klikevil your one seems to be to do with gnutls when the others are to do with libnss. Let's start. Anew issue and close this one off
