73 | # Darwin's getcwd(3) (which Cwd.xs:bsd_realpath() uses which |
74 | # Cwd.pm:getcwd uses) has some magic related to the PWD |
75 | # environment variable: if PWD is set to a directory that |
76 | # looks about right (guess: has the same (dev,ino) as the '.'?), |
77 | # the PWD is returned. However, if that path contains |
78 | # symlinks, the path will not be equal to the one returned by |
79 | # /bin/pwd (which probably uses the usual walking upwards in |
80 | # the path -trick). This situation is easy to reproduce since |
81 | # /tmp is a symlink to /private/tmp. Therefore we invalidate |
82 | # the PWD to force getcwd(3) to (re)compute the cwd in full. |
83 | # Admittedly fixing this in the Cwd module would be better |
84 | # long-term solution but deleting $ENV{PWD} should not be |
85 | # done light-heartedly. --jhi |
