Database locked using WebDav folder on Mac OS X

[astrodad]

Hullo,

I'm trying out using a calibre db on a webdav folder instead over sftp mapped drive but no matter what I try, I get a database locked error trying to run calibre with the webdav drive.

Here is the console output: any ideas?

I can open and write other files with no problem.

Try one of the solutions from here http://www.sqlite.org/cvstrac/wiki?p=SqliteNetwork

[astrodad]

How would one take advantage of any of these solutions without changes to the code?

Hmm i though usqlite would be a drop in replacement, but apparently not. Unfortunately, I dont have any experience with sqlite on webdav, so I don't have any insights to offer.

Maybe i'll take a look at what it would take to implement one of these. I've been making changes to my own build here, so this would be another step in my Python programming.
