thunar does not play nice with huge rclone remotes


Description Davide Palma 2019-03-28 13:03:48 CET
I have a Gentoo system installed with Thunar.
I have a huge OneDrive remote (with tens of thousand of files, some of them are GB-large) that I mount with rclone (v1.45) mount.
What rclone mount does is to setup a FUSE file system.
With GNU's coreutils I can cp,mv,ls with no problems.
When I try to browse this mount with Thunar, however it freezes for minutes or even hours.
My guess is that thunar tries to open the whole file, which needs to be downloaded and this takes time.
Probably this bug extends to every huge and low-bandwidth FUSE file system.

Thanks for reporting !

Could you please take a try if the bug can be reproduced with nautilus and nemo ?
These two and as well thunar use gvfs for remote file systems. If all 3 show the same bug, it could be a gvfs issue.

Another thing to try: In the thunar settings you can configure thunar to only generate thumbnails for local files. If thunar is configured to show thumbnails for remote files, this could explain the freeze for huge files .. since the thumbnailer actually would try to download every remote file.

Hi, sorry if I take a long time to answer but I'm busy with life (just don't assume I've abandoned the issue :) )
gio list and its deprecated counterpart gvfs-ls work fine. 
I still have the issue when I disable thumbnail generation.
I'll try nautlilus tomorrow...

Nautilus locks up as well, even though it handles it musch better than Thunar (it shows up a "loading" icon and the UI does not lock up)

Interesting .. so the changes are high that you hitted a gvfs bug.

You could try mounting the drive in console via "gvfs-mount" and see if any errors pop up / if you can reproduce the problem on console.

If yes, best check the gvfs bugtracker and report the bug there to get further help.

I can't use gio mount to mount the position as that is an rclone mount.
Anyway, I found out that the issue happens only with ISO files.

Ah, sorry, sure, it is mounted via rclone, not via gvfs. Possibly a bug in rclone ?

What about other file-managers ?  Nemo? (Possibly a gtk bug?)
Same for qt file-managers ? (e.g. dolphin ? )

Closing, since it looks like the bug is not thunar-specific
