Revision history for IPC::MMA

0.59003 Nov 6 2009
      * Fixed numerous C weaknesses in MMA.xs, that were revealed by 
        smoketest systems with more rigorous C compilers than gcc-x86.
        More such fixing may be needed.
      * Tried to fix a problem under perl 5.6, wherein storing into 
        UINT arrays gave unwarranted errors for values with the MS bit 
        set.  Fingers crossed for this perlguts issue!
      * 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.
