[Bug 468255] [NEW] renaming a shared folder from within nautilus causes inconsistent sharing information

[John Baptist]

Public bug reported:

Binary package hint: nautilus-share

What happens:

Renaming a shared folder from Nautilus stops the file from being shared
but keeps the sharing emblem.

What I expected to happen:

If you rename a shared folder, from either within Nautilus or from any
other program, it should continue to be shared.

To reproduce:

1. Create a new folder on your desktop by right-clicking and selecting Create Folder.
2. Share the folder by selecting its Properties dialog, Share tab, click Share this folder, and Create share. At this point, the folder will be shared and a sharing emblem will be added to the icon.
3. Close the Properties dialog.
4. Right-click on the folder and select Rename. Rename it to anything else.
5. Now open the Properties dialog again, Share tab. According to the Share tab, the folder is no longer shared, and it is not accessible from the network. However, the sharing emblem remains, indicating to the user that it is still shared.

Additional notes:

The same thing happens if you move the shared folder to another folder (in Nautilus), instead of renaming it.
Moving or renaming a shared folder not through Nautilus (e.g., with the mv command) does not cause this problem. Instead, it causes a different problem, that the share is completely forgotten (that is, both the emblem and the Properties dialog indicate that the folder is not shared). Later, if you create another new folder with the same name as the original, it will be shared, even though the user has not indicated that it should be (this is a security problem and might be a separate bug).

My opinion, if I may be so bold:

Tracking potentially moveable/renameable folders strictly by pathname is
not a good solution here. There should be another way to keep track of
which folders are shared, so that samba/nautilus-share don't get
confused when allegedly shared folders get moved. Possibly we need a
file reference object that will be updated automatically in response to
move/rename operations, like MacOSX's CFURL object.

Applies to nautilus-share 0.7.2-12 on Karmic.
