Revision history for IPC::MMA

0.81 Feb 27 2010

• Added an Example to the pod documentation (a user suggested this, it should also raise IPC::MMA's Qwalitee level :-)
• Undid some changes to C compiler testing in Makefile.PL, that were a bad idea.

0.7 Feb 21 2010

• Improved Makefile.PL to check more deeply for the presence and completeness of the mm library, to work around an Unknown test result on one CPAN tester's system.
• Improved C compiler testing in Makefile.PL to deal with compound names like 'ccache cc'.
• Corrected two method names in .pod docs from 'mm[a]hash' to 'mm[a]array'.

0.6 Nov 23 2009

• Added NaN filter to random DOUBLE generation in 04_fixedArray.t.
• Improved reliability/consistency of 09_lock.t operation by ** reworking delays/timeouts for slow/heavily-loaded systems, ** using a local copy of the global variable, and ** always checking the expected value of the local copy,

  as a condition for setting the next global value.

0.59009 Nov 19 2009

• Reworked test 09_lock.t to try to eliminate a FAIL on a CPAN tester's slow system.
• Reworked optimization selection in Makefile.PL to be more compatible with various toolsets.
• Eliminated error messages when NaN or inf values are stored in DOUBLE_ARRAYs. Random number generation in test 04_fixedArray.t will occasionally produce NaNs and infs.

0.59007 Nov 17 2009

• Modified Makefile.PL to work around some problems with the 'inline' keyword under the Sun C compiler.
• Built a Perl 5.6.2 with 64-bit integers and worked thru test problems using it.
• Improved test 04_fixedArray to test option MM_CSTRING as well as MM_FIXED_REC.
• Updated Makefile.PL prerequisites, abstract, author.
• Added test for .pod file.

0.59005 Nov 13 2009

• Found/fixed a nasty problem involving list operands of array push, unshift, splice.
• Improved UINT value-testing mechanism for perl 5.6.
• Revised test 4_fixedArray to use proper equality operator (== or eq) based on the type of array (perl 5.6 again)

0.59004 Nov 11 2009

• Another try to fix the problem under perl 5.6, wherein storing into UINT arrays gives unwarranted errors for large values.
• Improved the mechanism for eliminating 'inline' on cc's that don't support it.
• Yet another tweak to t/9_lock.t, which has still had some "hang at state 23" errors on some smoke-testers' systems.

0.59003 Nov 6 2009

• Fixed numerous C warnings in MMA.xs, that were revealed by smoke-test systems with more rigorous C compilers than gcc-x86.
• Tried to fix a problem under perl 5.6, wherein storing into UINT arrays gave unwarranted errors for values with the MS bit set.
• Removed -s option from 'which mm-config' command in Makefile.PL. Some which'es don't implement -s.
• Restricted cc '-Os' option (optimize for size) to those systems that can handle it (e.g., gcc).
• Restricted 'inline' functions to compilers that can handle them.

0.58001 Oct 23 2009

• Changed tests 5, 7, 8 to use /dev/urandom (or perl rand) rather than /dev/random to avoid entropy delays on newly-started Linux systems. Thanks to Oliver Paukstadt for this suggestion.
• Extended final timeout in test 9 to accomodate heavily-loaded smoke-test systems.
• Reworked detection of mm library in Makefile.PL. New version tries to balance the needs of smoke-testers vs. regular users. Thanks to David Golden for his advice on this.
• Added license=>perl to Makefile.PL to make YAML reviewers happy

0.58 Aug 15 2009

      Included revised t/2_mmArray.t to try to fix 0.54 failure 
      (inadvertently omitted from 0.55-57)

0.57 Aug 13 2009

• Used Devel::PPPort to add ppport.h file to distribution
• Included (in C preprocessor sense) ppport.h in MMA.xs
• With help of script in ppport.h, defined two symbols in MMA.xs that make ppport.h define required "IS_NUMBER..." symbols when they're not provided by an older Perl
• Added prerequisite for latest version of ExtUtils::ParseXS, an attempt to avoid some nasty-looking warnings in 'make' step, that I had just battled through on my own system
• revised t/9_lock.t in response to FAIL on 0.56
• added Devel::CheckOS to distribution and Makefile.PL, to restrict IPC::MMA install to OSes that mm runs on (Still no change to IPC::MMA itself since 0.54)

0.56 Aug 11 2009:

      Fixed some bad code in Makefile.PL of 0.55
      It shouldn't have worked but it seemed to for me.  Forget 0.55!

0.55 Aug 10 2009:

      Tests changed to avoid some problems found by CPAN testers
      Improved Makefile.PL to ask for mm library (to reduce UNKNOWN tests)
      (No change to IPC::MMA)

0.54 Feb 26 2009:

• Fixed boolean array operation on platforms with 64 bit integers
• Corrected the .pod docs some more

0.53 Feb 23 2009:

• Fixed 2 bugs introduced with the "minor improvement" in 0.51: ** the mm_sizeof routine wrongly computed when an allocated

  block could remain in place ** mm_hash_store used its return value in the wrong polarity

• Revised installation tests and the mm_alloc_size function so that they should succeed on more platforms.
• Also for CPAN testers, include Test::Warn as a prerequisite.
• Further tweaking of return values in functions that return lists.
• Documentation updated in several places.

0.52 Feb 15 2009:

• Set cc Optimize flag in Makefile.PL to optimize (0.51 was set for debugging).
• Return empty lists for exceptional conditions in functions that return lists.

0.51 Feb 14 2009:

• Added use tags (:basic :scalar etc) to .pod doc.
• Minor improvement in keeping shared memory blocks in place, when they don't have to be re-allocated.

0.5 Feb 13 2009: New package with largely IPC::MM compatible names.

      Retains direct call and tied interfaces for scalars and hashes.
      Adds direct-call and tied array functions with multiple storage
      types, including general purpose, signed and unsigned integer,
      floating point, boolean, and fixed-length records
      (a.k.a. maximum-length strings).

      BTree functions are retained as aliases for Hash functions.
      Hash functions return keys in sorted order, which was the
      main difference of IPC::MM's BTree mode compared to Hash mode.
