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