Trash not emptied with folders from other partitions

[Tsu Jan]

When a folder from a partition other than the home partition is put into the trash, the trash can't be emptied with middle-clicking on the dustbin applet. I get an error like this:

------------------
vfs.c:cairo_dock_gio_vfs_empty_trash:1624) [0m
gnome_integration : Error removing file: Directory not empty
GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Error removing file: No such file or directory
------------------

The GError part can be fixed by using "g_file_delete (file, NULL, NULL)" in that section of the function "cairo_dock_gio_vfs_empty_trash", which is related to the deletion of info files.

To fix "Error removing file: Directory not empty", in the same function, I added "G_FILE_ATTRIBUTE_STANDARD_TYPE" to "cAttributes" and set the following condition in a proper place:

if (iFileType == G_FILE_TYPE_DIRECTORY)

{

 cairo_dock_gio_vfs_empty_dir (sFileUri->str);

}

I've attached a patch.

Thanks a lot for this clear patch !
I apply it immediately on my branch :-)

forgot to mention that the patch has been included, thanks again for your help!

BTW, as you may know, Trash applet can't remove files with names containing "%". Do you think that there's a bug in g_file_delete()? Is there any workaround in that case?

[Fabounet (fabounet03)]

I didn't know.
is there a difference if the file is in the home dir, or if it's on another
volume ?
the '%' char is used to escape characters, so maybe there is a conflict
here, but I don't know on which side.

That only occurs for files in the home dir.

For a file "a%b" in other volumes, sFileUri in cairo-dock-gio-vfs.c is of the form ".../a%25b", while if the same file is in the home dir, sFileUri is ".../a%b".

[Tsu Jan (tsujan2000)]

I forgot to add that if the file "a%b" is inside a folder in the home dir Trash, the Trash will be emptied correctly!

[Fabounet (fabounet03)]

good job ! :-)
I can find a workaround, however your latest remark makes me feel like it's
a bug in gio/gvfs.

I'm afraid you've put the following line at a wrong position after "if (cFileName && *cFileName == '\\')" in cairo-dock-gio-vfs.c:

   g_file_delete (file, NULL, &erreur);

It should be below this conditional:

   if (iFileType == G_FILE_TYPE_DIRECTORY)
   {
    _cairo_dock_gio_vfs_empty_dir (sFileUri->str);
   }

Otherwise, only the contents of a (nonempty) folder -- and not the folder itself -- would be deleted on emptying the trash of another volume.

[Fabounet (fabounet03)]

you're perfectly right, thanks ! :-)
by the way I've commited a patch for the '%' problem too.

Thank you for that neat workaround! It fixed the problem.
