SIGSEGV Address Boundary Error when adding podcasts, and a Pango error when removing podcasts. #304

Open Zachs-Kappler opened 6 years ago

Zachs-Kappler commented 6 years ago

Well, I thought the error with adding and removing podcasts was fixed, but it still crashes. It gets weirder, as the actions are being performed and are reflected in Vocal after reopening it. I'll include the terminal output of both actions, but this is way better than nothing happening at all. I considered omitting the lines before the errors occurred, but maybe they might help.

elementary OS 0.4.1 Loki Vocal 2.2.0 from the AppCenter

I think I might have seen something similar when testing one of my PRs. https://github.com/needle-and-thread/vocal/pull/276#issuecomment-379514993 . It seems to happen when vocal is creating episodeDetailBoxes in the new episode view.

./com.github.needle-and-thread.vocal(vocal_episode_detail_box_construct+0xbe5)[0x4402d9]
./com.github.needle-and-thread.vocal(vocal_episode_detail_box_new+0x43)[0x4416b4]

./com.github.needle-and-thread.vocal(vocal_main_window_populate_views+0x1a30)[0x421efb]

Certainly for the first trace

psetq commented 6 years ago

Can these error be easily reproduced with the current version? Nevermind, I've been able to reproduce a couple of different errors when adding/removing podcasts. I'll create new issues once I'm able to narrow down the causes.

I'm getting some frequent errors/crashes when adding and/or removing podcasts, but they don't really seem to match the logs list above. The errors I'm getting appear to be *gtk_css* related. Not sure if I should open new issue or post backtrace here.

One example while removing a podcast:

xpaulnim commented 6 years ago

I think this issue and #311 are being cause by populate_views_async. Replacing it with populate_views seems to resolve the issue (It hasn't happened after subscribing and unsubscribing from a number of podcasts). The problem then becomes that vocal is not async.

I'm not sure why using an async would cause this.

I also see it crashing right after the Adding coverart to view. message with additional FATAL messages before finally dying. This happens repeatedly, even without interaction with the app and during listening to a podcast.

Unfortunately, I think many/most of those error messages are misleading. I've submitted a pull request to address the g_date_time_difference error, but I don't think that it's causing the crash.

I think, like xpaulnim pointed out is that the problem originates in the populate_views_async method. What I think is happening is that an already displayed UI element(s) are being updated from the background thread, which should not be done.

I was seeing crashes pretty regularly during background podcast updates and made a change (pull request #325 ) which defers updating the new-podcast UI to the main thread which significantly reduced the number of crashes I am now seeing (though I suspect this issue still exists in other areas/updates).

It's also be interesting to know which podcast caused the date errors, since the date parsing routine could probably be improved a bit ...
