The following (coarsely wrapped) is the proximate cause of a test failure in lib/findbin.t for perl-current@6450: $ ./perl -I../lib -MCwd=getcwd -lwe 'print getcwd' lstat(./../../../../../../../../../../../../../../../../../../../../../../../../ ../../../../../../../../../../../../../../../../../../../../../../../../../../.. /../../../../../../../../../../../../../../../../../../../../../../../../../../. ./../../../../../../../../../../../../../../../../../../../../../../../../../../ ../../../../../../../../../../../../../../../../../../../../../../../../../../.. /../../../../../../../../../../../../../../../../../../../../../../../../../../. ./../../../../../../../../../../../../../../../../../../../../../../../../../../ ../../../../../../../../../../../../../../../../../../../../../../../../../../.. /../../../../../../../../../../../../../../../../../../../../../../../../../../. ./../../../../../../../../../../../../../../../../../../../../../../../../../../ ../../../../../../../../../../../../../../../../../../../../../../../../../../.. /../../../../../../../../../../../../../../../../../../../../../../../../../../. ./../../../../../../../../../../../../../../../../../../../MachTen_Folder): No s uch file or directory at -e line 1 This, in turn is a result of the changes made to Cwd.pm by change 6429. I have not analysed what's going on, but I'd bet that it's something to do with MachTen, which is 4.4BSD UNIX hosted by Mac OS, being a "root in the sky" implementation: the UNIX file hierarchy sits under / (as one expects), but, (as one wouldn't expect), // is the Mac OS volume under which MachTen's files live. To round things off, /.. is equivalent to / (as one would expect). This is OK by POSIX, which says "[a] pathname that begins with two successive slashes may be interpreted in an implementation-defined manner, although more than two leading slashes shall be treated as a single slash." The clue is that /MachTen_Folder (a standard fixture in MachTen) is a symlink into a directory under the root in the sky, a directory that cannot itself be reached by going /.. (the parent of the root directory). $ ls -l /MachTen_Folder lrwxr-xr-x 1 root wheel 9 Jul 27 18:39 /MachTen_Folder -> //MachTen My guess is that the very long path above is too long for some system buffer or another, and that it is the truncated name that is "not found", so precipitating the error message. My (not disinterested) feeling is that Perl should work with systems whose idiosyncrasies are permitted by POSIX. Does this analysis make sufficient sense for you to be able to propose a fix, or would you prefer me to have a hack at the problem? -- Dominic Dunlop
