Hmph, is this find() under discussion the string.find() that finds a substring? You are doing >=0 comparison here, but with your example that entry["depotFile"] may have "base/" appended to what you expect, the result of running string.find() must yield "0", i.e. no extra prefix string, no? I kind of find it hard to believe that it is OK to have any extra prefix is fine ... >> The example in the Perforce man page for 'p4 where' would trigger this >> for example: >> >> http://www.perforce.com/perforce/r14.2/manuals/cmdref/p4_where.html >> >> -//a/b/file.txt //client/a/b/file.txt //home/user/root/a/b/file.txt >> //a/b/file.txt //client/b/file.txt /home/user/root/b/file.txt > > These are examples where a simple comparison as was implemented would work. ... so is this "find()" an attempt to catch prefix like "-"? Even if it that were the reason why you do not limit the acceptable return value from find() to zero, it feels a bit too loose to allow anything if the only thing you want to allow is a single "-" prefix. Can you explain this a bit better? I cannot quite tell what is going on from what was written in the log message. >> As an experiment, I hacked git-p4 to always use p4Where rather than >> getClientRoot(), which I would have thought ought to work, but while >> most of the tests passed, Pete's client-spec torture tests failed. > > That was exactly my first approach and got to the same conclusion.
