From 6f1dc21d983a495877c8054d41d9b634e234ccc4 Mon Sep 17 00:00:00 2001 From: Alex Vandiver Date: Thu, 9 Nov 2017 11:58:09 -0800 Subject: fsmonitor: read from getcwd(), not the PWD environment variable Though the process has chdir'd to the root of the working tree, the PWD environment variable is only guaranteed to be updated accordingly if a shell is involved -- which is not guaranteed to be the case. That is, if `/usr/bin/perl` is a binary, $ENV{PWD} is unchanged from whatever spawned `git` -- if `/usr/bin/perl` is a trivial shell wrapper to the real `perl`, `$ENV{PWD}` will have been updated to the root of the working copy. Update to read from the Cwd module using the `getcwd` syscall, not the PWD environment variable. The Cygwin case is left unchanged, as it necessarily _does_ go through a shell.
