1.871 Wed May 13 05:30:00 EST 2020

  * Reverted prior change. Skip unicode testing for MCE::Shared::Cache
    unless Perl has Scalar::Util 1.22 or later. It is too late at this
    stage for vendors to update Perl 5.10.1 on older Operating Systems.

1.870 Tue May 12 20:00:00 EST 2020

    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

  * 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

  * Bumped MCE dependency to 1.862.

1.861 Wed Sep 18 08:30:00 EST 2019

  * Hotfix for 1.849-1.860. The edge cases regarding signal handling have
    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.

    (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.

    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 }.

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

    Added parallel demonstration at the end of the documentation.

  * Bumped MCE dependency to 1.814 for the example to run.
  * Tweaked MCE::Shared::Ordhash and MCE::Shared::Server.

1.811 Wed Feb 15 17:00:00 EST 2017

    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.

  [BUG FIXES]

  * Fixed bug with MCE::Hobo for the Solaris platform.
  * Fixed race condition in Condvar->broadcast, ->signal, ->wait.
  * Fixed race condition in Queue->await.

    Bumped version to match MCE version.

  * Completed work supporting cyclical include of MCE Hobo.
  * Updated MCE::Shared to support Perl included with Git Bash.

1.102 Mon Jun 20 08:00:00 EST 2016

  * Updated logic for obtaining caller in several MCE::Hobo methods.
    This was missed in the 1.101 release.

1.101 Mon Jun 20 01:00:00 EST 2016

  [BUG FIXES]

  * Reverted a small change in Shared/Server.pm introduced in 1.100.

1.007 Wed May 25 16:00:00 EST 2016

  [NEW FEATURES]

  * Added chunk IO capability to READ in MCE::Shared::Handle. Both non-shared
    and shared handles are supported. See documentation for demonstrations.

  * Added assign to MCE::Shared::{ Array, Hash, and Ordhash }. Ditto, added
    hassign and lassign to MCE::Shared::{ Minidb }. Assign is inspired by
    Tie::Hash::Indexed v0.05_02. Thank you, Marcus Holland-Moritz.

  * Added META.json to the distribution.

  [ENHANCEMENTS]

  * Close shared file-handles when stopping the shared-manager process.
  * Improved exporting for shared MCE::Shared::{ Array, Hash, and Ordhash }.

  * Now loads PDL::IO::Storable automatically when PDL is present. PDL must
    come before MCE::Shared. Otherwise, load PDL::IO::Storable manually.

  * Specifying Sereal for serialization falls back to Storable when PDL is
    present. A warning is emitted indicating Sereal is not used.

  [API CHANGES]

  * Removed iterator and rewind functionality from MCE::Shared::Minidb.
    This was done to streamline Minidb and MCE/Shared/Server.pm.

1.006 Fri Apr 29 21:30:00 EST 2016
