Reset the BufferViewFilter after setting a new config

I'm not sure why, but somehow BufferView crashes in rare occasions because of invalid modelindexes
if we don't reset the BufferModel after setting its config. This is even true if we haven't set
a source model before, so an attached View couldn't even get any invalid indexes in the first
place. Anyway, it stops Quassel from crashing here, so I shouldn't complain, I guess.

This hopefully fixes #663, the Heisenbug that has haunted us for a long time now. At least for me.

Revert "Reset the BufferViewFilter after setting a new config"

No, doesn't fix #663. Also it has side effects with Qt 4.7 and some other bugs.
So bringing back the old workaround sigh

This reverts commit 617a3966941742a4e235af440d3665d0274354a8.

History

#1 Updated by jotik about 8 years ago

I think I discovered a way to reproduce this: Minimize Quassel to tray on startup when it's still connecting to the core. When the tray icon changes to show it has connected, click on that icon.

#6 Updated by Sputnick about 8 years ago

#7 Updated by jotik about 8 years ago

Strangely this does not happen to me at home, when I have AC power and a wired network.

#8 Updated by DevUrandom about 8 years ago

Some notes/workarounds from #710:
---

When I clicked the systray icon right after startup, Quassel crashed.
This was reproducable until I tried running Quassel in GDB, after which the issue apparently vanished.
---

Note also that it now became perfectly reproducible. Or in other words: Quassel is now totally unusable, since I can not restore the window anymore. (Every click on the systray icon, no matter when, will result in Quassel crashing.)
---

With my Quassel was also totally unusable. I have QuasselClient set up that it automatically connects to the core. I had to stop the core, start QuasselClient, wait for the error that it couldn't connect, start QuasselCore and then connect QuasselClient again, then I could use Quassel again.
---

I have found a way to "workaround" the crash:
If I am very fast and click the systray icon while the "Connecting..." dialogue is still open, I can access the Quassel window.
If I did that once, I can hide/restore the Quassel window with subsequent clicks on the systray icon without a crash.
---

Using the last method a lot, I do now have a few more tips:
You have to click right in the moment before/when the "Connecting..." dialogue closes. Clicking before that will not do anything, and clicking too long afterwards will result in the mentioned crash. The timeframe is about 1s on my computer (AMD X2 5k). If you train a little bit, you will be able to actually use Quassel quite reliably with this method.

#9 Updated by EgS about 8 years ago

  • Priority changed from High to Urgent

This sounds pretty much like a blocker... So I wonder why it isn't treated that way...

Anyways: as there's no tray icon on mac os, I can't reproduce this.

So anybody who has this issue:
1.) if you manage to run Quassel and have a visible mainwindow, please disable all treelike views. Those should be your buffer views (views -> buffer views) and the nicklist (views -> show nicklist). Disable all those views.
2.) Now try to reproduce the bug. If it still occurs please note here.
3.) If it doesn't occur. Bring back one view one at a time and always retry to reproduce the bug. please note when it does crash.

Thanks for your help.

Done.

It does not occur.

3.) If it doesn't occur. Bring back one view one at a time and always retry to reproduce the bug. please note when it does crash.

It occurs when clicking the menu item to show "All buffers". One time I was able to click that without making it crash, when I previously opened and closed the "Configure buffer views" dialog.

Additionally the crash also seems to happen when I try to start Quassel with some custom buffer view visible.

#11 Updated by Sputnick about 8 years ago

I would love to see a valgrind log of that bug. I can't reproduce with valgrind running, but maybe one of you can...

Just run
  1. valgrind --log-file=somelog.txt quasselclient

and attach the log. I'm still hoping to get some information out of that.

The trick is to wait. Longer than usual, because it is running in valgrind.

And here you go:

#13 Updated by DevUrandom about 8 years ago

seezer said on IRC that it works on Windows Vista x64. m4yer adds that it works on Mac OS X 10.5.7 as well.

Fancy, as there is no minimize to tray or even a tray icon on Mac OS ;)

#15 Updated by EgS almost 8 years ago

To those experiencing this issue:

If it's possible, please upgrade to Qt 4.5.2 and retest.

From the changelog:

- QSortFilterProxyModel
    * [250023]  Fixes QSortFilterProxyModel not reporting child if the model
      needs to fetchMore().
    * [251296] In dynamic filter model, children of temporarily filtered
      items were not correctly updated.
    * [252507] Show a warning instead of crashing if invalid indexes are
      passed.
    * [254234] Fixed setDynamicSortFilter not working when setting the model
      initially.

Issue 252507 sounds like a fit.

#21 Updated by bbigras almost 8 years ago

Until now I was using v0.5-pre (dist-84b0f5f) and was able to replicate this bug (or a very similar one).

Updating to d7832127ff8412b09d9fa4e56570d8a890abcbbe seem to have fixed the problem for me.

I tested just again: b819fa39f3053f047f5389456570d00020051688 is also already working.

#23 Updated by DevUrandom almost 8 years ago

Bisection shows that the issue was fixed in 119114e986ac8e05ca9698643cf749c24a1ef147. (f047a4f7add72ef7e32ad33f884e62a5773ecc72 still crashes, 119114e986ac8e05ca9698643cf749c24a1ef147 is the first to work)

#25 Updated by Sputnick almost 8 years ago

We have found a possible workaround (sadly not a real fix) for this and put it in git master: http://git.quassel-irc.org/?p=quassel.git;a=commit;h=119c23602ed1aa956d756ad6f56adb05cad1f815 (this patch should cleanly apply to 0.4.x too, if someone wants to try it out in the branch).

Could affected people please try out current git master and see if this issue is still present?

#26 Updated by Sputnick almost 8 years ago

  • Target version deleted (0.4.3)

#27 Updated by jotik almost 8 years ago

I have now been using Quassel 0.5_rc1 with Qt 4.5.2 on Gentoo for some time now and I haven't been able to reproduce this crash lately.

#28 Updated by johu over 7 years ago

  • Status changed from Confirmed to Assigned
  • Assignee set to Sputnick

check if this is done and resolve issue with correct version it was fixed

#29 Updated by johu over 7 years ago

  • Status changed from Assigned to Feedback

please give feedback, if this is resolved with quassel 0.5.2 or higher

#30 Updated by DevUrandom over 7 years ago

I am using 0.6_betaSomething and havent had this issue in a while. Remembering talking to Sput and that it might have been some kind of Qt issue.

#31 Updated by johu over 7 years ago

  • Status changed from Feedback to Closed

#32 Updated by Sputnick over 7 years ago

  • Status changed from Closed to Feedback
  • Priority changed from Urgent to High

This is not to be closed yet, as we've had an ugly workaround (that caused side-effects) in the code for the past release cycle.

I'm disabling the workaround now to see if the root issue is still around. Please report if you get such a crash again with current master (0.7-pre).

#33 Updated by Sputnick over 7 years ago

  • Status changed from Feedback to Resolved
  • % Done changed from 0 to 100

#34 Updated by Sputnick over 7 years ago

  • Status changed from Resolved to Assigned

Reopening, as the issue still isn't fixed. It avoids the crash in some specific instances, but it's still possible to corrupt our models, so we still have to find the root cause.

#35 Updated by Anonymous over 4 years ago

#36 Updated by Sputnick over 2 years ago

  • Subject changed from Crash on systray icon click to restore window to Crash when disabling uniform row heights for BufferView
  • Status changed from Resolved to Assigned
  • Priority changed from High to Normal

Seems like disabling the setUniformRowHeights() workaround lets me reproduce this 100% of the time when using Qt5. So reopening this for further investigation - sometimes Qt complains about invalid model indexes, so there's still something foul in our models, it seems...

FWIW, I see the same issue in my own (PyQt-based) project:

https://github.com/The-Compiler/qutebrowser/blob/66ec4f05990c52523bf76f3fef8b5098ab7bbb41/qutebrowser/completion/completionwidget.py#L114-L120

It's using quite simple QStandardItemModels, with a QSortFilterProxyModel. The only tricky thing it does is sometimes switching models. Other than that, no idea what triggers it, though I haven't investigated since finding the workaround here.
