Now, it USED to work under Wine. It no longer does. The program coughs up an error "No access to directory", and stderr shows a bunch of "LockFile not supported in server" errors.
LockFile didn't change AFAICT. What may have changed is: - timing of some operations may have changed (and if LockFile is really used & several threads/processes are used, this changes the whole picture) - reading operations has been a bit improved (which comes back to bullet above) But, I don't think those would lead to the no access to directory error. I think it's more something in the file management code which can play in this area, not the file locking.
Are there plans to add LockFile support into Wine?
they've been some talks of implementing it lately, but not lots of very conclusive so far.
A+
