Hi!
PhysFS has a bug in the ZIP archive module, function zip_find_start_of_dir.
Upon encountering a substring match, rc is set to a wrong value. The fix is
simple: swap both assignments like this:
[patch below --Ed.]
Some additional info for testing: Symptoms when you encounter this bug: A dir
is reported as empty although it has files in it; prerequisites or
encountering it: two dirs, one a substring of another, like "data/txt" and
"data/txt2", laid out in a way so that variable "middle" points to a file in
txt2 at some point during zip_find_start_of_dir
By the way, if you're interested in where PhysFS is used: I found this bug
while writing a patch for DOSBox (http://dosbox.sourceforge.net) to support
ZIP files. And I'd love to see that enhanced PHYSFS_mount syntax in an
official release soon *hint* ;);)
