./devel/p5-IPC-Shareable, Tie a variable to shared memory

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.13, Package name: p5-IPC-Shareable-1.13, Maintainer: pkgsrc-users

IPC::Shareable allows you to tie a variable to shared memory making
it easy to share the contents of that variable with other Perl
processes. Scalars, arrays, and hashes can be tied. The variable
being tied may contain arbitrarily complex data structures -
including references to arrays, hashes of hashes, etc.


Required to run:
[lang/perl5]

Required to build:

Log message:
(devel/p5-IPC-Shareable) Updated 1.06 to 1.13

1.13    2022-10-11
    - In singleton(), do a check whether class was sent in. There was a shifting
      issue if called with IPC::Shareable::singleton() as opposed to
      IPC::Shareable->singleton()
    - When an exclusive collision occurs and both 'graceful' and 'warn' are set,
      the warning thrown now includes the segment/semaphore key in use. This
      makes it easier to clean things up with 'ipcrm'

1.12    2022-03-13
    - Add tests in t/07-new.t to test how using tied() against a dereferenced
      variable returned from new() allows access to the underlying
      IPC::Shareable object
    - Reworked how spawn() and unspawn() manage things internally
    - POD updates, fixes and clarifications
    - Removed spawn() and unspawn(). There's really no need for these as one
      can simply create but not destroy

1.11    2022-03-07
    - Fix certain tests so they don't throw if we bail early

1.10    2022-03-07
    - Fix issue where if segments were created underneath of a parent by an
      external process other than the process that created the parent, the
      global register wasn't being updated, therefore those segments weren't
      being removed when calling clean_up_all()
    - All test files now check number of segments before and after the entire
      script has run, verifying that all segments were cleaned up ok
    - The test suite itself in its entirety makes sure that all segments
      created during the suite run are cleaned up properly
    - Added CI_TESTING=1 to coverage CI tests

1.09    2022-03-06
    - Made 81-fork_dup_rand_keys.t developer only (but still need to figure out
      why it only fails on FreeBSD)

1.08    2022-03-04
    - Added 'protected' option and clean_up_protected(). If set, the cleanup
      methods, nor the automatic 'destroy' functionality will remove the segment
      the option was set in, nor any children created underneath of it. A call
      to clean_up_protected() is required to remove them
    - Updated attribute tests to include all available options
    - _shm_key_rand() now checks EXCLUSIVE_CHECK_LIMIT times to find a key for
      a free segment. It croaks if not
    - Added _shm_key_rand_int() so we can mock it to test the dup random key
      checks
    - Added build prereq of Mock::Sub to test the random key function

1.07    2022-03-04
    - When running in forked environments, _shm_key_rand() was consistently
      returning the same 'random' key to each forked process. We've fixed this
      issue, and added tests for it (fixed by adding a call to srand() before
      rand)
    - Move $SIG{CHLD} handlers to spawn() and unspawn() instead of having them
      global (fixes #15)
    - t/65-seg_size.t fails on 32-bit perls; Add a check and bail if we're on
      a perl < 64-bit (fixes #14)

Log message:
Update to 1.06

Upstream changes:
1.06    2021-09-08
    - Fix significant bug where at least on MacOS, if we generated a CRC of a
      key that was greater than 0x80000000, it would round down the key to that
      number exactly, casuing duplicates, and incorrect segment access
    - Added new() method, returns a reference (default hash) without having to
      do the tie() directly
    - Modify t/65-seg_size.t beyond RAM max test to cover varying error messages
      on differing OSs
    - Renamed t/67-out_of_memory.t as the tests are related to exhausting SHM
      slots, not RAM

Log message:
Update to 1.05
Update DEPENDS

Upstream changes:
1.05    2021-07-16
    - Bump prereq version of Test::SharedFork to 0.35
    - Added ability to use JSON as the serializer
    - Added ipcs()
    - Added test to ensure we croak if data size is greater than segment size
    - Added 'tidy' attribute, removes unneeded nested structure segments
    - In SharedMem, added _key attribute, and added set/get methods
    - Changed key generation from using padding, pack and unpack to using
      String::CRC32's crc32(), which allows arbitrary, unpadded strings
    - Added attributes() allows fetching one, or all of the object's atttributes
    - Added 'limit' attribute, by setting false, allows a user to set a segment
      size larger than our internal 1GB default
    - Cleaned up exception throwing (particularly if seg size eats up all
      memory, we throw an appropriate message)
    - Display proper exception if we try to exhaust all available shared memory
      segments (fixes #3)

1.04    2021-06-28
    - Skip unspawn tests for perls with -Duselongdouble, as Storable is not
      compatible storing/retrieving such numbers (closes #5)

1.03    2021-06-25
    - Add newline to singleton() warn so that it doesn't print out trace info

1.02    2021-06-25
    - Remove erroneous listing from MANIFEST
    - Work around issue in t/65-seg_size.t where MacOS and FreeBSD don't have
      the -i flag to ipcs (thanks for the PR, Roland Walker!)
    - Added singleton(), ensures that only a single instance of a script can
      run at any given time
    - Added tests to ensure we croak() if create is not set and the segment
      doesn't yet exist
    - Fix POD issue where we stated exclusive returns undef instead of croaking
      (fixes #10)
    - Change 'perl' shell call to $^X in t/71-unspawn.t (fixes #6)

1.01    2021-06-24
    - Added 'graceful' flag option. With exclusive, if a second process
      attempts to tie an exclusive segment, we exit gracefully instead of
      croaking

1.00    2021-06-09
    - Project adopted by Steve Bertrand
    - Added global_register() and process_register() to return the
      registries of active segments and semaphores
    - Added seg() and sem() methods, returns the structure of a shared
      memory segment and a sempahore respectively
    - Added initial "persist" hash variables. Separate processes (even
      multiple files in multiple windows) can share a variable, and it'll
      remain available even after all processes exit. The variable will be
      re-attached if the same shared segment key is used in subsequent runs
    - Reversed order of Changes file
    - Removed trace() and debug() code for ease of reading
    - Improved exception/error messages, added exception testing, reduced
      and minimized the number of exceptions actually uncaught
    - Significant POD cleanup
    - 100% rewrite of all test files, and added a slew of new ones, all
      using Test::More
    - Add build requirement of Test::SharedFork to handle the out of
      sequence fork() tests in t/35-clean.t and t/30-lock_operations
    - Major POD updates
    - Added tests to prove that RT 123057 isn't really an issue (ie. segment
      size parameter works correctly)
