I have found an incompatibility between VMWare Fusion (Windows guest) with TortoiseSVN. TortoiseSVN is a windows client that is an interface to Subversion ISVN).
In my current setup, I have the working copy files on the host files sytem, and am trying to update and commit from within the Windows Guest. The problem is that everytime I try to commit, numerous files get made read-only during the first part of the operation (this is not supposed to happen) and then the commit fails because of the read-only files.
I have done this many, many times now, and the problem seems to occur on a random subset of the SVN files. Although it should not be necessary to say this, I am sure that many responders to this thread will be wondering: no, not in 3 years of daily use has this problem ever occurred in the native Windows environment.
For my next step, I am going to try moving the working copy files back into the VM.
Has anyone else seem this problem?
