History of Win32::API perl extension.

2015-05-26  Win32::API v0.82    bulk88
   - Fixed, missing MANIFEST entry caused GCC 32 bit builds to be broken

2015-05-26  Win32::API v0.81    bulk88
   - Fixed #104426, GCC 32 bit build uses real assembly code and a real
     (GNU) assembler instead of inline assembly, Borland C support, if it still
     worked, has been removed
   - 30-40% startup time improvement ("timeit perl -e"require Win32::API;
     Win32::API->import();""), and 632 KB less memory used on startup
     on 32 bit threaded 5.22 Perl ("perl -e"system 'pause'; require Win32::API;
     Win32::API->import(); system 'pause'"")
   - Fixed, setting $DEBUG in a BEGIN block, which is described in the POD
     but didn't actually work and was ignored from a BEGIN block
   - Debug mode code is now compiled away using constant folding, undocumented
     runtime setting of $DEBUG has been removed
   - Win32::API::Test is no longer installed, it is never needed outside of
     testing, this saves disk space

2015-05-14  Win32::API v0.80_02    bulk88
   - Improvements to debugging mode for RT #104426

2015-03-05  Win32::API v0.80_01    bulk88
   - additional diagnostics for
     http://www.cpantesters.org/cpan/report/fa1749cc-6bf4-1014-a4f8-5a5c5d380f5a

2015-03-05  Win32::API v0.80    bulk88
   - Fixed RT #100666, newer Cygwins strnicmp link failure in Callback.xs

2014-08-25  Win32::API v0.79    bulk88
   - promote to release version

2014-08-04  Win32::API v0.78_02    bulk88
   - Fixed, trial release for
     http://www.cpantesters.org/cpan/report/f6bd6af0-1a3b-11e4-b698-db7a2867dcfa

2014-08-02  Win32::API v0.78_01    bulk88
   - Fixed, trial release for
     http://www.cpantesters.org/cpan/report/e98d4c80-198a-11e4-b698-db7a2867dcfa

2014-07-29  Win32::API v0.78    bulk88
   - Fixed, POD (khw, bulk88)
   - Win32::API::Callback and Cygwin fork incompatibility noted
   - Fixed, RT #94906, signed integral return values that were shorter than an
     IV and whose value was negative, were returned as large unsigned numbers
     in Perl

2014-01-09  Win32::API v0.77    bulk88
   - Improved, hardened tests for error code returned by API/More's new()
   - Improved, new() is more resistent to future changes in LastError clearing
     behaviour in MS's Windows API
   - Fixed, in some rare cases with very wrong parameters being passed to new()
     no error code was set
   - Deprecated, Win32::API uses Win32 error codes, not C/Unix error codes,
     assigning low numbered Win32 error codes to $!, results in $!
     stringification to Unix descriptions, not Win32, therefore only $^E and
     GetLastError may be used to retrieve the error code of a failed API
     constructor call

2013-11-24  Win32::API v0.76_05    bulk88
   - Added, Cygwin 64 bit support RT #90597

2013-10-12  Win32::API v0.76_04    bulk88
   - Fixed, a lie in the POD for Type.pm, about the Type database
   - Fixed, using Perl 5.6/MakeMaker < ~6.25 caused Makefile.PL to generate
     a syntax erroring makefile
   - Added, beginnings of MSYS compatibility (Thanks to Sebastian Schuberth)
   - Fixed, many POD typos by David Steinbrunner
   - Fixed, removed use of "package ExtUtils::MM_Win32;" in Makefile.PLs for
     MSYS compatibility
   - Fixed, substr bug by Sebastian Schuberth
   - Fixed, thread_fails.t crashes due to race freeing the callback function
     stub
   - Improved, Win32::API::Callback::IATPatch::DESTROY optimization

2013-07-04  Win32::API v0.76_03    bulk88
   - Fixed, rebuilt API_test64.dll to fix a problem where Debug CRT was required
     by manifest but not by import table, this caused API_test64.dll to be
     unloadable on many x64 CPANTesters machines
   - 2 Makefile.PL files are not executable in the CPAN tarball anymore for
     Kwalitee reasons

2013-06-27  Win32::API v0.76_02    bulk88
   - Fixed, on 32 bits, Call_asm since 0.76_01, in Visual Studio, even with
     symbols loaded, lost the the part of the call stack behind Call_asm in VS
     debugger, while in the body of Call_asm, in a crash this made debugging
     harder by showing a corrupt or incomplete call stack, the prologue code was
     reworked to enable traditional EBP walking
   - Changed RaiseException/TerminateProcess on ESP inconsistency to a catchable
     die() if no C debugger is attached, community opinion from PerlMonks, if
     C debugger is attached, then Win32::API crashes to enable examination of
     process state
   - Added, previously (v0.76_01) 32 bit VC-only stack checking/ESP
     inconsistency now works on 32 bit GCC for __stdcall/__cdecl mixups only,
     not for wrong number of params (C stack overwritten)
   - Fixed, iat.t fatally exits after "ok 23" with "Usage:
     Win32::API::Callback::IATPatch::new(classSV, callback, HookDll,
     ImportDllName, ImportFunctionName) at t/iat.t line 163." on 32 bit Mingw
     Perl with 64 bit IVs (all of iat.t is skipped on 32 bit Cygwin Perls with
     64 bit IVs, so test was never executed before), reported by kmx
   - Fixed, when using Win32::API::Import, the API object internally created was
     leaked, now when the sub is freeded, the API object also is destroyed, this
     might unload the DLL being called, previously the DLL referenced by a
     ::Import was never unloaded except at interpreter exit
   - Fixed, Win32::API::More::Import created Win32::API objs,
     not Win32::API::More
   - Fixed, POD had erronous commas in code samples, UseMI64 code example didn't
     match current behaviour
   - Improved, the internals of a Win32::API obj were reorgranized for more
     speed
   - Improved, POD for NULL pointer for letter 'P'
   - Improved, mangle_simple_struct in API_test*.dll was made less noisy during
     a make test
   - Improved, ::Import created subs are now faster than doing $api->Call(,
     pre 0.76 Import time 0.85us per call, 0.76 alpha pure Perl Import time
     0.69us, 0.76 XSUB Import (final) 0.34 us, regular ->Call( is 0.40 us, a
     regular XSUB wrapper of the same C func is 0.22 us for comparison,
     *internals* The Call() XSUB is not written in XS anymore but plain C. This
     allows some R/W optimizations to the interp struct in the header of Call()
     and simplifies Import vs ->Call differences.
   - API Change, Import now returns a API obj ref, previously it returned a
     1/0 bool scalar
   - API Change, new and Import now check to make sure a sane number of params
     are passed and die otherwise RT#82611 txn-1183194
   - Under undef-ed NDEBUG and/or DEBUGGING, a wrong assert happened in
     my_find_mg on old Perls that need my_find_mg
   - Improved, XSUB Import is down to 0.24 us which is only .02-.03 us longer on
     benchmark vs regular XSUB.
     *internals* TARG is now used and sv_set* instead of allocating new SVs,
     this is the largested drop in time. 2nd biggest time win was getting rid
     of the inefficient implementation of memcopy in MS CRT. Also cpu uops
     reduction around the incoming args loop. A bunch of asm shifts, scales,
     Mod R/Ms, --/++s, and adds were removed by C code modification.
   - TODO REMOVE TEST CODE, alloca was rewritten for Visual C for speed and not
     cause extends of the C stack, this is dangerous so rewrite this with push
     asm ops from template param array in control
   - Fixed, WIN32_API_DEBUG build option now works on GCC
   - Fixed, the "Win32::API a function was called with the wrong prototype..."
     message had a typo

2013-03-26  Win32::API v0.76_01    bulk88
   - Fixed RT #82611, make tool detection in Makefile.PL didn't work for
     absolute path make tools, also removed a "dmake:  makefile:  line 276:
     Warning: -- Macro `CCFLAGS' redefined after use" warning
   - Fixed RT #83191, C stack not aligned to 16 bytes on x64
   - Improved, ::API->Call() is much faster now
   - Added, a limit of ~65K parameters per C function prototype was added
   - Added, on VC 32bit, Win32::API detects (TODO, dies) __stdcall funcs that
     were called with the wrong prototype, or __stdcall/__cdecl mixups, similar
     to VC's stack pointer Run-Time Error Checks feature
   - Improved, API_test64.dll was rebuilt with a dynamic CRT, dozens of KBs
     smaller
   - Fixed, threading_fails.t skipped on unthreaded Perls (Perl 5.6 related) to
     stop crashes
   - Fixed, 32 bit Strawberry Perl 5.8.9 with GCC 3.4.5 now builds and passes
   - Now requires Encode::compat, not Encode::, hopefully will enable
     automatic building on Perl 5.6
   - Win32::API is faster on 5.10 than 5.8 (HvNAME related)
   - Win32::API on 32 bit Windows has a little bit more optimization on Visual C
     than on Mingw GCC

2013-01-09  Win32::API v0.75    bulk88
   - Fixed/added, alpha Perl 5.6.2 support has been added, ::API will compile,
     will not crash except for randomly threading_fails.t . Many tests fail due
     to prerequities not being met. 00_API.t should pass on 5.6.2 with zero
     failures WITHOUT prereqs. Other tests require Math::Int64 and
     Encode::compat.
   - Removed, distropref workaround for ActiveState's PPM system (AS fixed it)

2012-11-21  Win32::API v0.74    bulk88
   - Fixed, non threaded Perl fix from Reini Urban
   - Fixed, Perl 5.8 in Struct.pm syntax error (cpantesters report)
   - Fixed, LNK 4210 warning on >= VS 2005 fixed
   - Fixed, misc POD

2012-10-20  Win32::API v0.73    bulk88
   - Known Issue, IATPatch usually does not work on Cygwin
   - Fixed, now works on 32 bit Cygwin Perl
   - Fixed, now works on 32 bit Perl with 64 bit IVs
   - Fixed, misc POD
   - Added, check for cygpath tool on ::API for Cygwin 
   - Fixed, cygpath fix from Jerry D. Hedden
   - Fixed, ::Callback's DLL failed to load in DynaLoader on newer
     (Strawberry Perl 5.16.*) Mingws due to newer Mingws starting to always
     include Static TLS in DLLs
   - Fixed, ::API on newer 32 bit Mingws (Strawberry Perl 5.16.*) crashed on
     all cdecl calls due to different optimization defaults in newer Mingws
   - Improved, some tests were hardened
   - Fixed, should build on ActiveState's PPM system

2012-10-16  Win32::API v0.72    cosimo
   - Improved Callback tests by properly detecting native or ithreads
     fork capability. Thanks to Steve Hay for the patch.

2012-10-15  Win32::API v0.71    bulk88
   - API Change, UseMI64 changed to always return old value, not old on no
     setting and new on setting
   - Added, "in" for ::API and "out" for ::Callback are automatically
     treated as Math::Int64 objects if they are refs, a call to UseMI64 is
     recommended but not mandatory now
   - Half Fixed, on a fork, the child interp free the parent's Win32::API DLL
     HMODULE causing access violation, though a problem with unicode path names
     containing characters not in the local CP probably exists
   - Added, support for forking to Win32::API/Win32::API::More, not ::Callback
   - Added, support for WINAPI, NTAPI, CALLBACK, WINAPIV calling conventions
   - Added, Win32::API::Callback::IATPatch

2012-08-16  Win32::API v0.70_02    bulk88
   - Added, typedef() in ::Struct now aborts and warns when encoutering an
     unknown type rather than creating a garbage struct definition
     (http://perlmonks.org/?node_id=978468)
   - Added, new() in ::Struct now aborts and warns when encoutering an 
     unknown type, rather than silent failure and a 0 byte long struct buffer
     being passed to the C func
   - Fixed/Added, pointers to other ::Struct types now supported in ::Struct
   - Optimized, trim down 32 bit asm code and Call() in ::API, untested 64 bit
     IV on 32 bit support in ::API
   - Optimized APIPARAM struct
   - Fixed, in Call() some of the callbacks trashed the 1st parameter on the PL
     stack, which cause no symptoms since it was the ::API object which was read
     from the PL stack much earlier in Call()
   - Fixed some no symptoms problems with using a stale local SP in Call()
     after a callback, which in a million to once chance might have been
     reallocated during the callback
   - Added 'void' as a type, it is an alias for VOID, which is a 'c'/char
     maybe this needs to be revisted one day because a void function does
     not return a char, but returns garbage on 32 and 64
   - Added, for C proto API objects, struct type is checked against supplied
     struct object, dies on failure
   - Fixed, bug was can not create an alias to char * from ::Type::typedef,
     the alias is to char instead of char *, C function gets a extended char
     instead of pointer
   - Changed, Carp is used in more placed in ::Struct
   - Added, SafeReadWideCString function
   - Fixed, a length checking bug in WriteMemory
   - Fixed, creating an API object, with ::Callback or ::Struct as return type
     now fatally errors in new() instead of silent failure and being a void
   - Optimized, removed CRT initialization code on MSVC
   - Added, 'V' now works for "in" letter protos, it is equivelent to ""
   - Added, strict, warnings, and pod testing globally

2012-08-16  Win32::API v0.70_01    bulk88
   - broken CPAN package, useless

2012 never CPAN released  Win32::API v0.70    bulk88
   - Added, Callback now works on x64
   - Added, Quads on API and Callback for 32 bit perl, they are
     8 byte strings or Math::Int64 objs on 32 bit perl 
   - Added, floats and doubles work in Callback
   - Callback has been rewritten, much less C and machine code, more Perl
   - Fixed RT #55660 and #77677, nonvolatile registers were corrupted on x64,
     especially if more than 4 parameters

2012 never CPAN released  Win32::API v0.69    bulk88
   - Fixed RT #12057, dll leak if func not found
     (https://rt.cpan.org/Ticket/Display.html?id=12057)
   - Fixed RT #77048, shorts and short typedefs crashed since 'S'
     was mapped wrong to structs, fix in Win32::API::More, struct now 'T'
     in ::More, 'S'/'s' now dies on Win32::API if not Win32::APU::Sturct objs,
     not crashes
     (https://rt.cpan.org/Ticket/Display.html?id=77048)
   - Fixed RT #77055, returned numbers are always signed, unsigneds
     fixed in Win32::API::More
     (https://rt.cpan.org/Ticket/Display.html?id=77055)
   - Fixed RT #77182, "int* var" works, "int *var" unparsable,
     fixed in core and ::More
     (https://rt.cpan.org/Ticket/Display.html?id=77182)
   - Fixed/Added RT #39810, in Win32::API::More for C proto created objs,
     pointer to numbers are automatically packed and unpacked, now 1234 or
     0x04D2 not "\xD2\x04\x00\x00", feature was implemented but broken
     previously
   - Fixed, on x64 float "in" params were broken, in 0.68, 4 byte floats were
     converted to 8 byte doubles of the same (approx) numeric 
     value when being prepared for XMM register loading, a C func 
     that takes floats will read 4 bytes from an XMM register, not 8
   - Fixed, on x64, for msvc builds, the callstack was lost during
     Call_x64_real
   - for a func with char * as return type, NULL caused crash, and perl
     memleak if it didn't crash on 32bit, char * as a return type's handing
     is still very flawed, signed/unsigned doesn't work, float * doesn't work,
     if the char * is dynamically allocated by its source, it is leaked
   - for a func with char as return type, undef was always returned, fixed
   - void ** and something ** don't parse, now errors out cleanly on a **
   - stability improvements to Win32::API::Callback, -Od, -O1, -O2 and
     Incremental Linkings/ILT now ok on MSVC 2003
   - on 32 bits, funcs with float return type were silently never called, fixed
   - if a buffer overflow for pointers is detected, a die is thrown, unless env
     var "WIN32_API_SORRY_I_WAS_AN_IDIOT" is set
   - Added, adding unsigned or signed prefixes to C prototype for char
     family (in only, out not implemented) cause numeric treatment for the
     scalar parameter, not string
     treatment, previously unsigned/signed were unparsable
   - Added Win32::API objs from non-DLL function pointers
     use as "$function = new Win32::API::More(undef, 123456, 'GetHandle',
            'P', 'I');", 123456 is the function pointer

2012-04-10  Win32::API v0.68    Cosimo

   - Temporarily skip RT#53914 related Callback test that's crashing
     for everyone and CPAN testers too.

2012-02-14  Win32::API v0.67    Cosimo

   - Fix a problem in 0.66 that prevented successful build and install
     of Win32::API. In other words, v0.66 is unusable! Stay away.
     Thanks CPAN testers!

2012-02-13  Win32::API v0.66    Cosimo

   - RT#74578 about structs alignment calculation should be fixed.
     Thanks to Douglas Wilson (DOUGW) and Reini Urban!

2012-02-12  Win32::API v0.65    Cosimo

   - No changes other than passing all files through perltidy

2011-08-28  Win32::API v0.64    Cosimo

   - Small improvement to Makefile.PLs to build or not build
     the Callback module depending on architecture (64 bit archs
     by default don't build Callback, it's known to fail tests).

2011-07-19  Win32::API v0.63    kmx

   - Fix for the strawberry perl 5.14.1/x64
     the upgraded gcc toolchain (4.4.6) uses different underscoring

2011-03-26  Win32::API v0.62    Cosimo

   - Skip Callback/t/03_Jim_Shaw.t test as it's reported failing
     on both 32-bit and 64-bit architectures.

2011-03-22  Win32::API v0.61    Cosimo

   - Fixed build process that was failing due to missing *.h
     and *.asm files in the MANIFEST

2011-03-19  Win32::API v0.60    Cosimo

   - Added *preliminary* x64, 64-bit, support.
     Now the test dll also ships with a x64 build
     and an updated VS solution file with Release and Debug x64 builds.

     Many fantastic people helped with 64 bits support:
     https://rt.cpan.org/Ticket/Display.html?id=55660

   - Fixed RT #48006
     (https://rt.cpan.org/Ticket/Display.html?id=48006)

   - Added a minimal TODO file, so I can remember where I left off

2009-07-02  Win32::API v0.59     Cosimo

   - Fixed compilation with gcc/mingw 4.4.0, thanks to Reini Urban.
     (RT#47398, https://rt.cpan.org/Ticket/Display.html?id=47398)

2009-01-17  Win32::API v0.58     Cosimo

   No significant updates for normal users.
   Developers instead please update to v0.58.
   Now you can play with the API_test.dll.

   - Test DLL MSVC project files updated to MSVC 2008.
     Now I will be able to add new tests (__cdecl)
   - General cleanup of tests and removed some warnings

2008-10-16  Win32::API v0.57     Cosimo

   - Re-added source code for the API_test DLL.
     Still needs to be adapted to be built with GCC/MinGW
     and different Makes, but it's a start.

2008-10-03  Win32::API v0.56     Cosimo

   - RT#39730 (http://rt.cpan.org/Ticket/Display.html?id=39730)

     Now passing a Perl undefined value to an API imported with
     a prototype, automatically turns it into a NULL value.
     Thanks to Ikegami for his bug report and patch.
     Added a new test case.

   - Fixed MSVC compiler version detection in Win32::API::Test.
     Thanks to Salvador Ortiz Garcia (sog at msg com mx)

   - Fixed several compilation warnings on `Callback.xs'

   - Started some work to support double*. Halfway through.

2008-03-23  Win32::API v0.55     Cosimo

   - Integrated patch from Salvador Ortiz Garcia (sog at msg com mx)
     which fixes RT #14660. There was a bug in arguments type packing
     unpacking of char* (and other pointer types).

2008-03-04  Win32::API v0.54     Cosimo

   - Try to clean up this big OS check mess.

2008-03-02  Win32::API v0.53     Cosimo

   - Devel::AssertOS came out unauthorized.
   - META.yml was outdated and wrong.

2008-03-01  Win32::API v0.52     Cosimo

   - Devel::AssertOS was not properly set up in 0.51.

2008-03-01  Win32::API v0.51     Cosimo

   - Cleaned up API.pm pod docs and clearly stated Win32::API license
   - Fixed $$/pid tests for Cygwin
   - Now uses Devel::AssertOS to check that we are on a Win32 or Cygwin
     system. This should ease the work of CPAN testers.

2008-02-23  Win32::API v0.50     Cosimo

   - Fixed RT #31702 (http://rt.cpan.org/Public/Bug/Display.html?id=31702)
     Thanks to RUrban for supplying the fix.

2008-02-20  Win32::API v0.49     Cosimo

   - Fixed the stack cleanup assembler statements for GCC in API.xs, I hope.
   - Fixed a Borland C macro definition in API.xs
   - Fixed META.yml (stupid me)

2008-02-20  Win32::API v0.48     Cosimo

   - Finally applied the cdecl/stdcall patch available since long time
     from http://www.xs4all.nl/~itsme/projects/perl/.
     Now Win32::API *can* work with cdecl DLLs.
     Fixes RT #32424 (http://rt.cpan.org/Public/Bug/Display.html?id=32424)
       and RT #24685 (http://rt.cpan.org/Public/Bug/Display.html?id=24685)
     Thanks to Willem Jan Hengeveld (itsme at xs4all.nl) for your great work.
     Thanks to JimK for a test case and to BrowserUk and others at PerlMonks
     for providing me useful information and complaints. :-)

     However, still missing some GCC assembler magic for stack cleanup.
     Any help?

   - Clarified licensing info. Yes, Win32::API is available with
     GPL 2 / Artistic license.

2007-11-12  Win32::API v0.47     Cosimo

   - Nothing exciting. Fixed warning on DATA filehandle.
     Reported by Dmitri Karasik. Build passed on Windows Vista.
     Fixes RT #30674 (http://rt.cpan.org/Ticket/Display.html?id=30674)

2006-12-23  Win32::API v0.46     Cosimo

   - Test suite now passes on MSVC6, MSVC7, GCC/MinGW and Cygwin.
     A lot of skips and segfaults on doubles/floats should be examined,
     though. But now it's possible to cleanly install from CPAN!

   - API_test.dll building phase has been removed. Now there is only
     a prebuilt version of it, suitable for all compilers to link and
     use, I hope.

     Why does Cygwin gcc compile an entirely different API_test.dll?
     I checked the tdump of msvc and gcc and the gcc version is
     missing all the kernel32 imports. I don't know why this happens.

   - Removed README.txt file. Now there's only README.

2006-11-29  Win32::API v0.45     Cosimo

   - What a mess! Restored GCC/MinGW compile that broke with that
     damned assembler macros...

2006-11-28  Win32::API v0.44     Cosimo

   - Fixed compile under MSVC broken with GCC/MinGW last changes.

2006-11-28  Win32::API v0.43     Cosimo

   - Now Win32::API should cleanly *compile* on GCC / MinGW
     environment. This has been tested only Vanilla Perl and
     only with Microsoft nmake.
     Test suite does not work with GCC. You can only test that
     Win32::API extension works running manually the t\99_GetProcess.t
     test script.
     This improvement comes thanks to the 0.42 patches I found
     and collected from the internet, though I don't know who
     is the guy that wrote them first. Anyway, thank you!

   - There are problems with current ExtUtils::MakeMaker (6.31 and
     also blead, I believe) version and dmake generated Makefiles.
     I'm trying to understand what to do here.

   - Win32::API::Type now doesn't have a INIT block anymore, that
     seems to be the cause of all evils on this module.
     Please you out there report your findings on this.

   - Last but not least. Current maintainer of Win32::API is now
     Cosimo Streppone (me), cosimo at cpan.org. I'm not very
     skilled on Win32 development, but I'm trying to to work out the
     CPAN bugs queue. Thanks to Aldo for handing me his wonderful
     work maintainance.
