in reply to Rename unreliable on Windows

Script runs fine for me; no crashes. Windows 2008 R2, Perl 5.12.4.

I suspect you're triggering some sort of race condition in Windows' file locking, but even if I removed the print to STDOUT to try to speed things up, I wasn't able to trigger it. Sleeping for a few microseconds before calling rename might help.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

    Thanks, I tested this with usleep 50000; but it didn't help. See resolution above (backup software was locking files).
      Good catch.   Points out that any operation that might possibly fail, especially when run on end-user machines (that are commonly less-privileged than the [foolishly, too privileged] developer machines), should trap for runtime errors with eval or otherwise, and be prepared to handle them plausibly.

    Should cpanminus be part of the standard Perl release?
