rebuild_index fails on windows

[gregmuellegger]

Hi, I tried to use xapian with django haystack on windows.

If I try a rebuild_index I get the following:

Traceback (most recent call last):

WindowsError: [Error 32] Der Prozess kann nicht auf die Datei zugreifen, da sie
von einem anderen Prozess verwendet wird: 'C:\\Users\\Frank\\Documents\\SVN_Fran
k\\geitmann.de\\web\\xapian_index\\

The german message means something like "The process cannot access the file because it's used by another process."
The rebuild_index works if we replace the first line of the def clear() method with a return :-)

So I assume, removing the directory while the library holds the lock fails under windows. Maybe releasing the lock first would help, or to avoid removing the whole directory.

Does this happen every time you try to rebuild the index or was there by chance an update happening at the same time?

[gregmuellegger]

Yes, this happens everytime. It is a local development installation,
no cronjobs or anything were accessing the project.

Should be resolved in SHA 37add92. Will not attempt to establish a WritableDatabase connection prior to shutil.rmtree. Will now only do so if cherry picking documents to remove.
