I'm running latest client (38ef52) available in manjaro linux with nautilus 3.14.2. When creating a new folder, owncloud starts syncing right away but when renaming the folder, a standard procedure after creating a new folder, it crashes. Is there any way I can debug?

Did you try running it inside gdb?

gdb --args /usr/bin/owncloud --logfile -

Then on crash you do:

Nautilus, owncloud is running fine. Will try to get a backtrace

Interesting, while and after running nautilus in gdb it didn't crash anymore. Will try to reproduce this

Got it. Does this help already or do i need more debug symbols?

Do you have the Nautilus integration for the icon overlays inside the sync folders running?
If you disable it does it crash too?

@piratenpanda

Yes, python-nautilus is installed. Will try without

Seems to work fine without

dragotin commented Apr 7, 2015

hmm, are you sure that the python-nautilus does match the nautilus version that is running? I.e. if you updated nautilus to a more recent version that is not bin compatible to the python bindings, that might crash.

@piratenpanda

I'm using the one available in arch so i dont have a choice really. Icons and updating the icons while syncing works fine.

It works just fine on fedora 20 x64 (nautilus 3.10.1, nautilus-python 1.1) , same OC client version as piratenpanda with icon overlays running. All packages from official repos.

@piratenpanda Unfortunately the backtrace doesn't tell me much. Would you be up for testing a couple of things?

Open your installed syncstate.py (probably in .../share/nautilus-python/extensions/syncstate.py):

  • line 151: 'return []' instead of 'return'?
  • line 182: remove 'Nautilus.ColumnProvider, '

It that doesn't do it, let's try to narrow down the problem locaton:

  • remove the whole MenuExtension class, does it work now?
  • remove the whole SyncStateExtension, does it work now?

I'm somewhat suspicious of how the script stores the FileInfo items it gets from update_file_info() - it may need to be rewritten to use the async update_file_info_full()...

@piratenpanda

Changing the two lines didn't help. And i noticed renaming works fine a few times and then it crashes for the n-th time you rename folders.

Removing the MenuExtension class doesn't change it.

When removing the whole extension i can't get nautilus to crash

@piratenpanda Thanks for the test! Removing only the SyncStateExtension makes it work, correct?

@piratenpanda

Author

When you mean deleting the file in the python-nautilus extension directory then yes

ckamm commented Apr 8, 2015

@piratenpanda No, I mean removing everything between class SyncStateExtension and the end of the file.

@piratenpanda
Copy link
Author

ah ok, i misunderstood because the file is called syncstate.py and in an extension dir. Let me try it now.

@piratenpanda

Removing the SyncStateExtension class seems to "fix" it, yes

ckamm commented Apr 8, 2015

@piratenpanda Okay, thanks. Unfortunately that means it'll probably not be a simple fix. I think we can't store the FileInfo objects we get from update_file_info. Instead we'll likely have to use update_file_info_full. See https://projects-old.gnome.org/nautilus-python/documentation/html/class-nautilus-python-info-provider.html.

@piratenpanda I now installed everything in a VM with archlinux, nautilus 3.14.2 and owncloud 38ef52. I can't reproduce the problem. I'm creating new folders and renaming them immediately or after a short pause. Is there anything in particular I should try?

@piratenpanda

I have to create a few folders quickly in sequence. And after a few times it crashes.

ckamm commented Apr 9, 2015

I've now made 35 folders in quick succession in various subfolders but can't reproduce it. :/

This makes it less clear that there's an actual bug here. I'll ask someone from nautilus-python whether our usage of update_file_info is safe - but it's not necessary for 1.8.1.
