________________________________________________________________________________ Win32::UTCFileTime, Version 1.52 ________________________________________________________________________________ Revision history for Perl extension Win32::UTCFileTime. _________________ v1.52 25 Oct 2009 - Updated Module::Install components from version 0.91 of that distribution. - Updated ppport.h using version 3.19 of the Devel::PPPort distribution. _________________ v1.51 11 Oct 2009 - Declare all core module dependencies in the Makefile.PL as well as the existing CPAN module dependencies. (Cf. [cpan #50107].) _________________ v1.50 25 Aug 2008 - Silenced a warning from Visual C++ 8.x onwards, which now defines time_t as a 64-bit integer by default. A better solution to take advantage of the larger time_t size may be forthcoming. - Updated Module::Install components from version 0.77 of that distribution. - Changed the use of "eval { ... };" to test the return value rather than $@ since under certain circumstances $@ can end up undefined after a failed eval. _________________ v1.49 09 Jul 2008 - Changed dwDesiredAccess and dwShareMode flags in the CreateFile() calls in stat() and alt_stat() from GENERIC_READ and FILE_SHARE_READ to 0 and 0 as per the CreateFile() call in perl's own win32_stat(). This allows those functions to operate on a file that is opened by another process that is denying access to other processes trying to read the file. (Fixes [cpan #37535].) _________________ v1.48 06 Jul 2008 - Updated Module::Install::PRIVATE to version 1.06 for Makefile.PL improvements: * Added the magic "OS unsupported" phrase to Makefile.PL's die() message so that CPAN Testers report "N/A" rather than "FAIL" on OSes where the appropriate C compiler cannot be found. - Updated Module::Install components from version 0.75 of that distribution. Changed Makefile.PL appropriately to cope with a non-backwards-compatible change in the (undocumented) recommends() method. - Added full paths to Cygwin tools used when creating the distribution. _________________ v1.47 30 Jun 2008 - Added the magic "OS unsupported" phrase to Makefile.PL's die() message so that CPAN Testers report "N/A" rather than "FAIL" on non-Win32 OSes. - Updated ppport.h using version 3.14 of the Devel::PPPort distribution. _________________ v1.46 10 Jul 2007 - Updated Module::Install::PRIVATE to version 1.05 for Makefile.PL improvements: * Fixed the compiler version checking on Win32 for Visual C++ 8.x, which now uses four numbers separated by dots for its compiler version. - Updated Module::Install components from version 0.65 of that distribution. - Updated ppport.h using version 3.11 of the Devel::PPPort distribution. - Added comments to MANIFEST file. _________________ v1.45 14 Feb 2006 - Fixed all the functions so that they work correctly on FAT drives. Previous versions of this module made some erroneous assumptions about the behaviour of certain Win32 API functions that were used in the solutions implemented here, leading to incorrect behaviour on FAT drives. In fact, the test suite did not even pass all tests on FAT drives. The new solutions are much simpler, and all tests now pass on both NTFS and FAT drives, on Windows NT 4.0 Workstation, Windows 2000 Professional and Windows XP Professional (at least). Many thanks to Wayne Scott for drawing attention to these errors and for suggesting what the correct solution is. - Fixes for building with Borland C++: * Used instead of for the declaration of _getdrive(); * Added definition of _dev_t, which Borland C++ omits; * Skipped some directory mode tests because Borland's stat(2) sets the mode differently to Microsoft's stat(2), emulated by alt_stat(). This module should now build (and test) cleanly with Perls built using Borland C++ and dmake. - Changed various "use MODULE;" lines to be explicit about what is being imported, and in particular to not import things that are not required. - Updated Module::Install::PRIVATE to version 1.04 for Makefile.PL improvements: * Fixed the handling of user-input relative directory paths so that they are converted to absolute paths before use in case the Makefile.PL has changed to another directory in the meantime; * Renamed lots of methods for a better naming convention. - Updated Module::Install components from version 0.56 of that distribution. This includes Module::AutoInstall, which supersedes ExtUtils::AutoInstall. Changed Makefile.PL appropriately to take advantage of the new features. - Updated ppport.h using version 3.08 of the Devel::PPPort distribution. - Modified PREOP key in the dist option in Makefile.PL to ensure files are all Windows end-of-line format. - Corrected spelling mistakes and improved the grammar in some of the documentation. _________________ v1.44 02 Sep 2005 - Changed test scripts from using Test to Test::More for better diagnostic output in case of failures. - Updated Module::Install::PRIVATE to version 1.03 for Makefile.PL improvements: * Relaxed the compiler version checking so that only the major version numbers have to match (and also the minor version numbers for VC++ 7 and later, which use CRT DLLs named msvcr70.dll, msvcr71.dll, etc) (Thanks to Sisyphus for drawing attention to this problem via the PAR mailing list (par@perl.org)); * Fixed the parsing of bcc32's output as per perl change #24855. - Dropped the use of I<> for Perl variables in POD, in line with changes made (some time ago) to the perlpod manpage (perl change #12542). - Corrected spelling mistake: INITIALISATION should be INITIALIZATION. - Updated Module::Install and ExtUtils::AutoInstall components from versions 0.37 and 0.62 of those distributions respectively. _________________ v1.43 01 Jun 2005 - Updated Module::Install::PRIVATE to version 1.02 for Makefile.PL improvements: * ExtUtils::AutoInstall command-line options are now better supported, fixing problems with custom option handling that did not recognize them; * Errors now croak() rather than die() so that the error messages look a little more friendly; * If the "auto install" checks loaded Test::Builder then that module's cleanup diagnostic code is now skipped, which suppresses the somewhat confusing (given the context) message # Looks like your test died before it could output anything. in the event of any subsequent error that causes Makefile.PL to croak(). _________________ v1.42 03 Mar 2005 - Included Module::Install::PRIVATE version 1.01 for Makefile.PL improvements: * Added code to try to check that on Win32 the same compiler is being used to build this module as was used to build Perl itself to avoid problems with binaries built by different compiler versions loading different C run-time DLLs. - Added a recommendation for Test::Pod to Makefile.PL to test the POD when building these modules. Included ExtUtils::AutoInstall to facilitate this. - Updated ppport.h using version 3.06 of the Devel::PPPort distribution. - Corrected spelling mistakes: categorise, emphasise, initialise, realise, specialise, summarise and synchronise are more properly spelled categorize, emphasize, initialize, realize, specialize, summarize and synchronize respectively. - Corrected "daylight savings time" to "daylight saving time" (except in Microsoft Knowledge Base article titles) in the POD. - Fixed up copyright years in all files to reflect which files actually changed in each year. _________________ v1.41 12 Dec 2004 - Moved XSLoader::load() call inside BEGIN subroutine as recommended by the XSLoader manpage. This means that the XSUBs are now installed before the rest of the Perl module is compiled, and hence their prototypes are now known, and can be checked, during the remaining compilation. _________________ v1.40 31 Oct 2004 - Removed $Debug variable and introduced new $ErrStr variable. Instead of callers having no clue as to why a function failed unless an error happens to be in $! and/or $^E or they had $Debug set to a true value, they can now inspect the $ErrStr variable to obtain the reason for the failure, much like the use of $! and $^E themselves, except that $ErrStr will always be set when a function fails, even if the last error did not relate to a system call or Win32 API call. Note that $! and/or $^E will continue to be set as well wherever they were previously being set, so existing code that inspects those variables will not be affected. Callers should simply consider inspecting $ErrStr instead in the future. The only backwards compatibility issue here is the removal of the $Debug variable, which is unlikely to affect most production systems. - Updated documentation and tests for these changes. - Renamed some functions, macros and external variables in the XS and C code to use names that are more likely to be unique to this code, namely Win32UTCFileTime_*() for functions, WIN32_UTCFILETIME_* for macros and win32_utcfiletime_* for external variables. - Introduced use of *MY_CXT* macros etc for handling static data in the C code to make the module thread-safe. - Reinstated ppport.h to provide *MY_CXT* macros etc for Perls older than 5.7.3 (or 5.9.2 in the case of MY_CXT_CLONE). - Updated Module::Install components from version 0.36 of that distribution. _________________ v1.33 08 Aug 2004 - Added a check to the return value from the _get_osfhandle() call in the _SetUTCFileTimes() C function (used by the replacement utime() function) so that we do not try to continue with an invalid handle. - Also added an extra attempt at continuing in the above scenario by closing the previously opened file descriptor and trying to open an operating- system file handle directly instead, and modified the similar existing case intended to cover directories to always retry rather than only when errno was set to EACCES because (a) the debug message was misleading (errno is set to EACCES for read-only files too) and (b) errno is not always reliably set (see below). This module now appears to function correctly when built using the free Visual C++ Toolkit 2003 compiler in conjunction with a Perl (e.g. ActivePerl Build 810) that was built using Visual C++ 6.0. (Passing file descriptors, errno and other CRT resources between the msvcr71.dll and msvcrt.dll C run-time libraries used by those compilers respectively does not work.) Using such mismatched C run-times, however, has to be seen as undesirable and may not always work. Added a note to the INSTALL file that if possible the same compiler should be used to build this module as was used to build Perl itself. Thanks to Robert Rothenberg for drawing attention to this problem via CPAN Testers (http://testers.cpan.org/). _________________ v1.32 01 Aug 2004 - Removed standard modules from the list of pre-requisites in Makefile.PL (since a minimum required Perl version is given anyway). - Updated Module::Install components from version 0.35 of that distribution and changed Makefile.PL to use abstract_from() now that it is fixed. - Changed INSTALL document and Makefile.PL to remove requirement for Microsoft Visual C++, and mention dmake. - This module should now build cleanly with Perls built using MinGW / dmake. - Changed various standard C library function calls to their Perl replacement functions. - Improved warning and error messages to include the message string for the relevant standard C library errno or Win32 API last-error code where appropriate. - Fixed a bug in the _SetUTCFileTimes() C function (used by the replacement utime() function) in which a file handle was wrongly being closed twice. The inevitable failure of the second attempted closure had gone unnoticed because the error checking code was also faulty :( - Changed return value from the private _set_utc_file_times() XSUB so that if it fails when called in list context then it returns an empty list rather than a single "false" value (which would be seen as "true" in list context). (It is not currently called in list context anyway; this is just defensive programming.) _________________ v1.31 26 Feb 2004 - Use Module::Install as a front-end to ExtUtils::MakeMaker. The same build script can also be used as a front-end to Module::Build in due course (once problems building XS modules with Module::Build are ironed out), and it also creates a META.yml file that contains a "license" key, which http://search.cpan.org/ makes use of. - Added new test to check for POD errors if Test::Pod is available. _________________ v1.30 22 Feb 2004 - Changed stat(), lstat() and alt_stat() to use $_ if no argument is given, as per the Perl built-in functions. - Added new test script to exercise this new feature. - Clarified licence and warranty for the module, and included relevant licence files in the distribution. - Moved installation instructions to a separate INSTALL file. - Added PREOP to the dist option in Makefile.PL to ensure permissions are set correctly within the distdir (since they often are not set correctly in the top-level directory when working on Windows) to stop CPANTS from complaining about bad permissions. - Added COMPRESS (and SUFFIX) and ZIPFLAGS to the dist option in Makefile.PL to enable "best compression" for gzip when running "nmake dist" and for zip when running "nmake zipdist" respectively. - Added clean option to Makefile.PL to have the const-c.inc and const-xs.inc files deleted by "nmake clean". - Added MANIFEST.SKIP to stop "nmake distcheck" from producing bogus warnings. - Moved UTCFileTime.pm into lib/Win32/ sub-directory within distribution. This is the new layout style produced by h2xs as of version 1.23. - Removed ppport.h since no use was being made of it. (This module builds on Perl installations back to 5.6.0, both with and without ithreads, without needing any portability fixups.) _________________ v1.20 24 Sep 2003 - Introduced an alternative C stat(2) function from CVSNT and Perl code that can succeed in some cases where Microsoft's implementation fails. A Perl interface, alt_stat(), is optionally exported, and can be automatically tried by the replacement stat() and lstat() functions if the built-in functions that they call first fail. - Changed the replacement utime()s use of Perl's trick for making it work on directories too. The trick only works under Windows NT platforms, so it is more appropriate to try a more natural approach first and only fall back on the trick if that fails. This is the approach that Perl uses too. - Improved the replacement stat() and lstat() functions by having them fall back on CreateFile() if FindFirstFile() fails when getting the correct UTC file times. The file times can now be retrieved under Windows NT platforms for root (drive or UNC) directories, and for directories specified with a trailing slash or backslash. - Improved the detection of the filesystem when determining whether it stores UTC file times. - Cached the conversion of the base SYSTEMTIME to FILETIME for a minor speed-up. - Changed the output of debug information to use warn() rather than simply print()ing to STDERR to enable the information to be captured by a $SIG{__WARN__} handler if required. - Added new test scripts to exercise the new and improved features. - Renamed some functions in the XS and C code. - Reverted the typemap for "const char *" back to the default T_PV. There did not seem to be any point in the custom typemap. - Changed tabs to spaces (via "expand -t 4 infile > outfile") to avoid irritation when switching between editors that use 4- or 8-space tabs. - Added META.yml (courtesy of ExtUtils::MakeMaker 6.17). _________________ v1.10 23 Jun 2003 - Incorporated improvements to the underlying C code from CVSNT code. The DST season transition dates are now correctly calculated (assuming that they are not determined by year-specific clues), rather than assuming the United States' rule applies. _________________ v1.00 05 Jun 2003 - First released version. _________________ v0.01 20 May 2003 - Original version; created by h2xs 1.22 with options: -n Win32::UTCFileTime -b 5.6.0 ________________________________________________________________________________
