Revision history for Perl module MCE::Shared.
1.869 Mon May 11 22:00:00 EST 2020
* Disabled unicode testing for MCE::Shared::Cache on Perl 5.10.1.
Testing for keys containing unicode is failing on RedHat 6.x,
but passing in meta::cpan (smoke tests). Thank you, Paul Howarth.
* Share array and hash deeply; only when using the TIE interface.
This resolves an edge case for the OO interface and passing
nested items during construction. Thank you, Nick Tonkin.
* Bumped MCE dependency to 1.868.
1.868 Sun May 10 22:00:00 EST 2020
* Completed threads-like detach capability in MCE::Hobo.
1.867 Sun May 03 18:00:00 EST 2020
* Bug fix for UTF-8 issues during inter-process communication.
This update required undoing optimizations specific to scalar args.
Essentially, IPC involves serialization for everything going forward.
Install Sereal::Encoder and Sereal::Decoder for better performance.
* Improved MCE::Hobo with threads-like detach capability. See POD.
Resolved MCE::Hobo stalling MCE::Shared::Server during global cleanup.
* Improved IPC in MCE::Shared::Queue with permanent fast-like dequeue
including dequeue_nb. Going forward, the fast and barrier options are
silently ignored if specified (i.e. no-op).
* Improved IPC performance on Linux.
1.864 Wed Dec 04 13:00:00 EST 2019
* Use monotonic clock if available in MCE::Hobo->yield.
See https://www.perlmonks.org/?node_id=11109673
* Bumped MCE dependency to 1.864.
1.863 Sun Nov 26 20:00:00 EST 2019
* Use MCE::Channel for MCE::Hobo->yield to not incur unnecessary delays
due to busy shared-manager process.
* Re-factored recent changes regarding IPC safety in MCE::Shared::Server.
This update defers signal handling for HUP, INT, PIPE, QUIT, TERM, and
custom handlers during IPC without incurring a performance penalty.
See POD section labled "DEFER SIGNAL" in MCE::Signal 1.863.
* Reverted $hobo->exit back to sending the SIGQUIT signal in MCE::Hobo
now that MCE::Shared::Server defers signal during IPC.
* Improved reliability for spawning MCE::Hobo inside threads including
nested parallelization, made possible using a global lock $MCE::_GMUTEX
in MCE 1.863.
* Updated signal handling in mce-examples/framebuffer on GitHub.
* Bumped MCE dependency to 1.863.
1.862 Wed Sep 18 22:00:00 EST 2019
* Hotfix for 1.861.
* Bumped MCE dependency to 1.862.
1.861 Wed Sep 18 08:30:00 EST 2019

been finally resolved for MCE::Hobo. Thank you, Richard Kelsch for the
use case involving ctrl-c. See mce-examples/framebuffer on GitHub.
* Bumped MCE dependency to 1.861.
1.860 Sun Sep 15 20:00:00 EST 2019
* Signal-handling update release.
* SIGINT and SIGTERM safety for shared objects during IPC.
* IPC safety in MCE::Hobo during SIGINT and SIGTERM.
* Method $hobo->exit in MCE::Hobo now sends the SIGINT signal
for extra reliability with MCE::Shared (previously SIGQUIT).

* Bumped MCE dependency to 1.845.
1.844 Wed Aug 14 21:30:00 EST 2019
* Completed validation running Kelp and Raisin apps with MCE::Shared.
For example, constructing shared objects at the top of the script
(i.e. MCE::Shared->scalar, MCE::Shared->cache, et cetera).
Shared objects are accessible by Plack workers (i.e. Starman).
* Disable internal signal handling for the shared-manager process
if spawned from inside a thread or process.
* MCE::Hobo workers exit immediately upon receiving a SIGSEGV signal.
This safegaurds IPC from stalling inside the manager process.
* Enhanced the _wait_one private function in MCE::Hobo.
* Removed Prima from the list for auto-enabling the posix_exit option.
Prima (since 1.52) is parallel safe during global cleanup.

1.839 Sat Aug 25 13:00:00 EST 2018
* Seeds the Math::Random::MT::Auto generator automatically when present
in MCE::Hobo, similarly to Math::Random and Math::Prime::Util, to avoid
child processes sharing the same seed value as the parent and each other.
The new seed is computed using the current seed.
* Updated MCE::Shared::Cache to support optional argument "expires_in" for
set and sugar methods.
* Updated MCE::Shared documentation.
* Bumped MCE dependency to 1.837.

See http://www.perlmonks.org/?node_id=1199760
and http://www.perlmonks.org/?node_id=1199891.

See http://www.perlmonks.org/?node_id=1200960.
* Bumped MCE dependency to 1.831.
1.831 Tue Sep 19 23:00:00 EST 2017
* Resolved crash on the Windows platform for older Perl (< v5.18).
Older Perl must continue to run the shared-server as a thread.
Thank you CPAN testers, CHORNY and NONAME.
* Re-enabled Condvar testing on the Windows platform.
1.830 Fri Sep 15 23:00:00 EST 2017

* Do not enable barrier mode for Queue if constructed inside a thread
or for the fast => 1 option.
* Fixed leaked handles during destruction; MCE::Shared::{ Condvar, Queue }.
* Updated MCE::Shared to not croak when running Perl in taint mode via
perl -T. Failing -T was MCE::Shared::{ Handle, Sequence, and Server }.
* Bumped MCE dependency to 1.827.
1.822 Sun Apr 02 23:00:00 EST 2017
* Is now safe running MCE::Hobo with the Wx GUI toolkit (wxWidgets).
* Bumped MCE dependency to 1.826.
1.821 Sun Apr 02 07:00:00 EST 2017
* Updated MCE::Shared::Queue. The following provides a comparison
for the enhancements made regarding IPC during 1.818 through 1.821,
in order to run on machines having "many" cores. I ran with 12, 96,
and 192 workers on an 8 core box.
Shared queue, dequeue 100k items.
my $Q = MCE::Shared->queue();
# Must start the manager manually when IO::FDPass is missing.
# This caveat applies to Condvar, Handle, and Queue.
MCE::Shared->start() unless $INC{'IO/FDPass.pm'};
$Q->enqueue( 1 .. 100000 );
$Q->end();
MCE->new(
max_workers => 12, 96, or 192,
user_func => sub {
while ( defined ( my $item = $Q->dequeue ) ) {
;
}
}
)->run();
MCE::Shared 1.821: 12 ~ 1.325 secs 96 ~ 5.206 secs 192 ~ 8.158 secs
MCE::Shared 1.825: ~ 0.913 secs ~ 1.068 secs ~ 1.560 secs
* Results were captured on a fast 8 core system running CentOS Linux 7.
The thing to take from this is that running many workers "no longer"
results in up to 6.2x penalty regarding IPC.
* When IO::FDPass is missing, croak with error if constructing a Condvar
or Queue and forgotten to start the shared-manager process manually.
* Bumped MCE dependency to 1.825.
1.820 Sat Apr 01 01:00:00 EST 2017

* Bumped MCE dependency to 1.821.
1.816 Mon Mar 06 13:00:00 EST 2017
* Optimized SHIFT and UNSHIFT methods in MCE::Shared::Ordhash.

* Added MCE::Hobo + Gearman demonstrations (xs and non-xs) on GitHub:
https://github.com/marioroy/mce-examples/tree/master/gearman_xs
https://github.com/marioroy/mce-examples/tree/master/gearman
* Changed kilobytes and megabytes to kibiBytes (KiB) and mebiBytes (MiB)
respectively inside the documentation.
* Having IO::FDPass is beneficial for Condvar(s), Handle(s), and Queue(s).
Thus, append IO::FDPass to PREREQ_PM if we can and not already installed.
Run MCE_PREREQ_EXCLUDE_IO_FDPASS=1 perl Makefile.PL to bypass the check.

and shared handles are supported. See documentation for demonstrations.
