- BUG FIXES
- Fixed typo in MCE::Step POD (RT#95250) (Florian Schlich).
- Updated MCE::Util's get_ncpu function for AIX (Dana Jacobsen).
- Do not send a KILL signal after receiving a SIGPIPE.
- Fixed issue with Makefile.PL on defining the minimum Perl version.
- Use Scalar::Util (looks_like_number) for validation logic. The regex previously were insufficient for large numbers containing scientific notation. This impacted the sequence option in MCE.
- ENHANCEMENTS
- The mce-sandbox demo has been released on Github demonstrating Perl + MCE + Inline::C. The theme is Prime Numbers. This journey which began 2 years ago has been completed. There is also the mce-sort exercise demonstrating Perl + MCE + External C. https://github.com/marioroy/mce-sandbox (is thread-safe) https://github.com/marioroy/mce-sort (not thread-safe)
- A hard decision had to made for MCE, particularly Perl under Windows excluding Cygwin. MCE will now load the threads module automatically for Windows only. Folks may specify use_threads => 0 if threads is not desired. The reason for this is from seeing Math::Prime::Util crashing once workers exit. The same is true without MCE and forking a child process. Threads does not exhibit this behavior. It is a hard problem to solve. Why not default to threads for Windows since forking is emulated.
