Greetings,
During testing of the Perl MCE 1.608 module (uses flock), the examples
scripts hang. Downgrading the base Cygwin package from 2.3.0-1 to
2.2.1-1 resolves the issue.
Installation is not required if a Cygwin developer desires to test
file locking via the Perl MCE module.
https://cpan.metacpan.org/authors/id/M/MA/MARIOROY/MCE-1.608.tar.gz
1. extract tar file
2. cd MCE-1.608/examples
3. perl foreach.pl 10
Hangs with Cygwin 2.3.0-1
Successful with Cygwin 2.2.1-1
The upcoming Perl MCE 1.7 release does away with file locking and
works with 2.3.0-1. The next commit into GitHub (in a day or two) will
contain optimizations allowing Perl MCE on Windows and Cygwin to run
at full speed with lesser overhead.
Best regards,
Mario
p.s. Thank you for Cygwin
