What's even more interesting is that this gook has renamed themself to "Delta" a long time ago, but telegram-purple still tries to save the log with the old name.

bodqhrohro commented 2 years ago

Got again, this time with a channel that did not change its name ever.

Finally sacrificed some resources for the greedy Valgrind, and got this familiar crash quickly: pidgin-vg.txt.gz

Pidgin 2.14.8 были с ошибками сегментации и попытались просмотреть файл ядра.

@EionRobb, could you take a look please? Seems like the libnotify+ plugin is involved, not sure if this is related to the crash though.

bodqhrohro commented 2 years ago

Hehe, looks like some corruption issue was fixed there in 7987f8427b722a2edce75678254ad27ae56297d7987f8427b722a2edce75678254ad27ae56297d, but I didn't mind and used an outdated build from a 2016 year revision xD That's why make install is evil, folks!

Would upgrade this and other plugins that were possibly installed from sources, and report if some of the corruption issues still persist. It seems like the notification object may still exist and be used when the strings making it are already freed, which doesn't seem to be fixed yet.

This confirms an old hypothesis that some prpl incorrectly frees its connection data.

But how? @EionRobb, if the same memory area was freed before, Valgrind had to catch it too, right?

I see that tgl uses its own allocator, can it be that it conflicts with malloc?

И да, @vysheng, что в коде делает 0xbedabeda? «Как вы яхту назовёте — так она и поплывёт» ничему не учит? xDDDDDDD

Oh, and despite it happened just when I was starting Pidgin, it managed to disconnect and start reconnecting already. (Did I tell already that my machine barely carries Valgrind out and it runs extremely slow, right? :P)

EionRobb commented 2 years ago

@bodqhrohro there's definitely something weird with your setup :)

Can you try disabling all your plugins and see if it's still a problem. Did you end up updating your cairo libs?

bodqhrohro commented 2 years ago

Pidgin is kind of useless without ALL of plugins, how do you imagine this? xD I have had annoying crashes even with the builtin IRC plugin, and had migrated to other client for IRC (and recently from IRC at all, when Freenode was destroyed by separatists).

I may resort to some kind of binary search, but this is going to take a lot of time, as neither of the crashes is reliably reproducible, and "not crashing" is a false negative.

Did you end up updating your cairo libs?

Yup, before the latest crash.

EionRobb commented 2 years ago

I mean, it seems like you get a crash every day or two. Could you cope without any plugins (other than protocol plugins) for that long just to help rule it out?

Unfortunately none of the backtraces and valgrind dumps that you've posted to any of the prpls have been very useful this far, however they are all seemingly very similar to each other which makes me think it's something not related to each of the prpls you're posting the issues for

bodqhrohro commented 2 years ago

So, okay, I went through a journey:

And you know what? No crash has happened in the process, except for https://github.com/dm0-/window_merge/issues/35

How is that supposed to work? I warned about false negatives :P

Possibly some messages need to arrive before the memory gets corrupted, it also would explain the flakiness. I've noticed it often happens right after some message with a link, possibly other markup counts as well.

bodqhrohro commented 2 years ago

@EionRobb I've run Valgrind with --read-var-info=yes, did it get any more informative? pidgin-vg12.txt.gz At least lots of copying of freed memory is revealed, not sure yet if that is dangerous though.

EionRobb commented 2 years ago

Yeah, looks pretty bad. You should probably disable your telegram-purple accounts. It looks like the accounts are disconnecting and free'ing memory, but the libtgl engine is still trying to use that free'd memory.

bodqhrohro commented 2 years ago

I rolled tgl back to bec2e6d537c272ed185e8c41ff81b4b8521a131d, and Pidgin survived two sleeps already with no crashes. So it's definitely a bug in @himselfv's patch.

bodqhrohro commented 2 years ago

This one is still relevant though:

What's that? Just a memory exhaustion (unlikely)? Or a conflict between allocators?
