[Bug 530268] Re: MOVE_SELF handling renames the directory incorrectly

[Facundo Batista]

Note that this bug affects directly the Ubuntu One syncdaemon, because
it scrambles the file paths and mixes the metadata the user has for
them.

Status in “pyinotify” package in Ubuntu: Confirmed

Bug description:
I have a path fully watched. Rename one directory from "test_dir", to "test_dir_renamed" (note that they "overlap").

So, it gets into process_IN_MOVE_SELF(), and tries to fix the paths that it has in the watch managers.

In the loop where it checks which paths to choose, it gets:  "tests/home_dir/root/test_dir_renamed".

The src_path is:

    tests/home_dir/root/test_dir

The dest_path is:  

    tests/home_dir/root/test_dir_renamed

And the code *incorrectly* renames it to:

    tests/home_dir/root/test_dir_renamed/renamed

One way to avoid this overlapping issue is to add the "/" to the source_path, so you don't get in the trap of comparing with .startswith(). 

A patch is attached here that fixes the problem in the described way.
