Subject: CPAN.pm shell aborts without error message when trying to delete current directory
Download (untitled) / with headers
text/plain 2.9k
Module: CPAN VERSION 1.59_54 $ perl -v This is perl, v5.6.1 built for cygwin-multi Operating environment: cygwin version 1.3.9 When cpan shell tries to clean up it's path, if the current working directory happens to be one of the cpan cache directories that the shell is trying to clean up, the shell aborts without an error message and doesn't clean up the lock file. -------------- For example: ### NOTE: current directory is in the cpan cache and happens to be one that cpan is going to try to kill turnbullw@TURNBULL ~/.cpan/build/Math-Pari-2.010201 $ cpan cpan shell -- CPAN exploration and modules installation (v1.59_54) ReadLine support enabled Show quoted text

Contacting... Other job not responding. Shall I overwrite the lockfile? (Y/N) [y] n Ok, bye --------------- I think I've traced the culprit to line 869 of CPAN.pm which is this line File::Path::rmtree($dir); in sub force_clean_cache Apparently File::Path::rmtree aborts without an error message if it can't delete the current directory. After looking at File::Path, I think that ultimately this is really a bug with the rmdir function of this version of perl under cygwin. If rmdir is called on the current directory then perl 5.6.1 under cygwin aborts without an error message. Under ActiveState perl 5.6.1, I get: C:\temp\foo2>perl -e "rmdir 'c:\temp\foo2' or die $!; print 'ok'" Permission denied at -e line 1. Under cygwin perl 5.6.1 I get: turnbullw@TURNBULL /tmp/foo $ perl -e'rmdir "/tmp/foo2" or die "dead: $!"; print "ok"' turnbullw@TURNBULL /tmp/foo2 Notice that it just aborts. I will report this to the cygwin and perlbug lists but since it can cause CPAN.pm to fail I thought I should report it here as well. Regards, Rhet Turnbull
