Today, attempting to port SPrevayler to Squeak 3.9, I ran into a problem with the FilePlugin. It turns out the problem is already covered by a test case in the image, and that the test case is currently failing, at least on Linux on the versions of the VM I tried (3.7-7, 3.9-7, and svn trunk).
The problem is that FilePlugin is caching the
DIR* for the directory that was just deleted, and deleting the directory doesn’t invalidate the
DIR* cache. Adding a check against
dir_Delete solves the problem. Hopefully the fix will be included in mainline builds soon.
