The program aborts upon hitting page_down, after toggling tags on an item several times

lenormf commented 4 years ago

I originally thought this issue I'm hitting was #1460, but since the following reproducer is so different from the one in #1460, which I cannot reproduce, I'm reporting details here.

Describe the bug

alot crashes with signal ABORT.

Software Versions

Python version: 3.8.2
Notmuch version: 0.29.3
Alot version: 0.9 (also verified on master, 1e66a3d)

Archlinux.

To Reproduce Steps to reproduce the behaviour:

open a search buffer, search tag:inbox
hold the s key for ~10s, to mark the same item as read/unread in rapid successions
hit the page-down key

The crash doesn't occur with j or page-up.

But it does occur if you hit ctrl+d twice.

lenormf commented 4 years ago

I just reproduced the issue by only hitting s, so I suppose this could be a dupe of #1460 after all. At least we have a fast reproducer here!

pazz commented 4 years ago

Thanks for this. I can reproduce it as initially reported, but not just with the s key. If you'd take the helm on this one that'd be much appreciated. I don't really have the time to dig deeper into libnotmuch or its bindings. I wasn't even aware that there is a second verison of these bindings. Is it "official", i.e., part of nochmuch yet?

lenormf commented 4 years ago

I'll try to look into it, but no promises.

I was actually hoping you could answer those questions, which I asked in #1460 since you commented on the RFC for the FFI bindings.

The bindings were renamed into notmuch2 and are part of the upstream repository - just completely undocumented as far as I could see. There's even a request pending to have a Debian python3-notmuch2 package, to:

encourage new downstream development to rely on notmuch2 instead of on notmuch

lenormf commented 4 years ago

Got the following output for the first time while using the same reproducer above:

terminate called after throwing an instance of 'Xapian::DatabaseModifiedError'

Also got a stacktrace in the debug log, this time!

It doesn't throw the same error, but it shows that not all exceptions are caught properly.

I was hitting a segfault all the time with the same backtrace, using 424669b4e08dd841f499981bbce10c15a5c48463. I have now updated to 486df70dbaf31eaefd441f1f2f47c93d8a057fa6, using python3-notmuch2 from ubuntu 20.10. I get much less segfault, but I can reliably get a segfault with the steps to reproduce of that issue. This time, the stack trace is a little different (though similar):

You can find the full stack trace here (also with a version form bt full).

The end of my log file looks like this (having replaced names and email addresses):

Could you relay that to the notmuch list? Ideally as answer to my last mail on the python bindings segfaulting? Many thanks, P

I was hitting a segfault all the time with the same backtrace, using 424669b. I have now updated to 486df70, using python3-notmuch2 from ubuntu 20.10. I get much less segfault, but I can reliably get a segfault with the steps to reproduce of that issue. This time, the stack trace is a little different (though similar):

You can find the full stack trace here (also with a version form bt full).

The end of my log file looks like this (having replaced names and email addresses):

Hi! I am also affected by this. I confirm that adding the workaround above in hooks.py prevents alot from aborting after a few tags switchings.

pazz commented 2 years ago

Is this on the latest release or alot from git master?

This is 0.10 (the 0.10-1 package, from Debian unstable). Oh! I have just seen the commit on top of master from last month. That should also probably fix that issue, shouldn't it?

pazz commented 2 years ago

Yes :)

With the latest commit, I cannot reproduce the issue anymore, even without the workaround above. But it is true, as its description says, that it slows down a little the program, noticeably at startup. Thanks for the indication!

pazz / alot

The program aborts upon hitting page_down, after toggling tags on an item several times #1504
