[Changes for 1.009 - Mar 26, 2011]
* Bug fixes, etc.

• RT #53463: PAR::Packer 1.002 on HPUX 11.23 PA-RISC issue (HPUX) patch from Lars-Gunnar Taube
  • add SHLIB_PATH to ld_path_keys in myldr/mktmpdir.c
  • call "chatr +s enable ..." on the extracted custom perl
• RT #65535: Unable to run perl script packaged with pp under cygwin on another Windows XP installation
  • lib/PAR/Filter/PatchContent.pm: patch AutoLoader.pm to add "cygwin" to the list of "is_dosish" $^O identifiers; otherwise AutoLoader::find_filename() will mangle filenames that start with a drive letter
  • script/par.pl: use PAR::Filter::PatchContent to patch any modules embedded in the packed excutable; this supersedes the ad hoc patching of XSLoader.pm and will now also patch AutoLoader.pm
  • myldr/Makefile.PL: when generating $parl_exe or $parldy_exe make sure that we use the PAR::* modules (e.g PAR::Filter::PatchContent) from the build environment rather than a possibly installed older version
• "Fix" #64485: pp PodStrip module included document how to inhibit pod stripping (copied from PAR.pm POD)
• bump required Module::ScanDeps to 1.01 (hopefully fixes failures in t/90-rt59710.t with Perl 5.13.x)
• reworked the build system a bit to fix recurring problems with dmake on Windows and parallel makes in general:
  • copy myldr/{parl,parldyn} to blib/scripts from myldr/Makefile
  • myldr/Makefile was completely handcrafted; try to generate it using standard ExtUtils::MakeMaker tools as much as possible
  • generate myldr/{Dynamic,Static}.pm from templates {Dynamic,Static}.in
  • rename static.c to boot.c
• add "configure_requires" for ExtUtils::Embed
• pick up some POD spelling fixes from Debian (thanks, Jonathan Yu <jawnsy@cpan.org>)

[Changes for 1.008 - Nov 21, 2010]
* Bug fixes, etc.

• RT #61528: bug similar to RT 55994 (Windows) relax heuristic to check whether the configured C compiler is actually gcc (Ed Zagar)
• RT #61874: Windows: Packed executable handles wildcards different from script myldr/static.c: turn off automatic globbing of process arguments when building with MingW (Roderich)
• RT #62357: .cgi extension not taken as script call into Module::ScanDeps with $Module::ScanDeps::ScanFileRE set to qr/./ so that we don't discriminate against scripts that have an extension other than .pl, .pm, .al or .t (or no extension at all) (Roderich)
• RT #63083: pp: Undefined subroutine &DynaLoader::bootstrap called in pp-compiled bianry fix the name where the shared perl DSO ($libperl in myldr/Makefile.PL) is extracted to so that it matches the reference the linker wrote into $par_exe; heuristic currently only available for Linux (assuming we have GNU binutils installed), but might work on other ELF-based systems, too (Roderich)
• t/30-current_exec.t: fix a test failure on Cygwin (cygwin.dll was not on PATH) (Roderich)

[Changes for 1.007 - Sep 9, 2010]
* Bug fixes, etc.

• RT #56582: PAR-packer compilation on Windows XP32 box applied patch from Jean-Michel Male to fix building with Microsoft Visual Studio (Roderich)
• RT #50747: (no subject) finally use permissions 0775 in my_mkfile() (Roderich)
• require modern Module::Install (chorny) and update Module::Install et al. to version 1.00 (Roderich)
• RT #59710: Par-Packer not including all dependencies When cleaning @INC at the end of bootstrapping (just before we run the actual packed script) canonicalize $ENV{PAR_TEMP} before we use it to match elements of @INC. This works around non-canonicalized values (e.g. a trailing slash) for $ENV{TMPDIR} or P_tmpdir (as #define'd in <stdio.h>) (the latter seen on FreeBSD and OSX) (Roderich)
• RT #56020: PAR::Packer and PDF::API2 Unicode::UCD: failed to find UnicodeData.txt that's actually a bug in Module::ScanDeps); bump requirement on Module::ScanDeps to a versionthat has the fix (correct %Preload rule for Unicode::UCD)

[Changes for 1.006 - Jun 26, 2010]
* Bug fixes, etc.

• RT #58266: fix "install PAR::Packer failed for strawberry perl 5.12.0.1 (parldyn.exe not found)" Apparently exec() on Windows spawns the new process, but then exits immediately without wait()ing for the new process (observed at least on ActiveState Perl 5.10.1 and Straberry Perl 5.12.0.1). That causes myldr/run_with_inc.pl to return control to myldr/Makefile prematurely, causing (depending on timing) the build to fail. Work around this by using system() instead.
• While we're at it, clean up some dubious dependencies in myldr/Makefile.PL.
• Drop test_requires IPC::Run3 introduced in 1.005, simply skip all tests in t/30-current_exec.t when run in a path that contains spaces.

[Changes for 1.005 - Jun 05, 2010]
* Bug fixes, etc.

• RT #57494: add attributes.pm to list of always required modules (Roderich)
• RT #55994: fix "Can't call method "remove" on an undefined value at .../Win32/Exe.pm" (patch from DJIBEL)
• RT #57948: pp-generated executable and a missing dependency on libgccssjlj-1.dll (Roderich)
• RT #58095: test fails on OS X (when building in a directory with blanks in its pathname); NOTE: adds a test_requires on IPC::Run3 (Roderich)
• spring cleaning in myldr directory (Roderich)

[Changes for 1.004 - Apr 20, 2010]
* Bug fixes, etc.

• RT #52794, #56654: script/par.pl: remove munging of @inc on Windows; it causes problems with Strawberry Perl

[Changes for 1.003 - Apr 10, 2010]
* Bug fixes, etc.

• RT #56171: add PerlIO and PerlIO::scalar to the list of always required modules (Roderich)
• Fix t/30-current_exec.t failing when cwd contains regexp metacharacters (Niko Tyni)
• Link to repository in meta information (chorny)

[Changes for 1.002 - Dec 17, 2009]
* Bug fixes, etc.

• RT #52407: fix calls of sprintf in myldr/mktmpdir.c that rely on unspecified behaviour (output buffer is also among the input parameters). (Roderich)

[Changes for 1.001 - Nov 24, 2009]
* Bug fixes, etc.

• Fix to the rejection of "main.pl" as input scripts. Previously, we rejected /main\.pl$/, now we only reject files named "main.pl" as we should (Markus Jansen)

[Changes for 1.000 - Nov 22, 2009]
No functional changes since the latest development release.

But let's (finally) encourage the notion that this is production grade software by using a version >= 1!

[Changes for 0.992_06 - Nov 20, 2009]
* Bug fixes, etc.

• Attempt to fix build problems where PERL5LIB is used to include temporary build directories (Roderich)

[Changes for 0.992_05 - Nov 13, 2009]
* Bug fixes, etc.

• Apply patches from RT #49900: [PATCH] build problems (Marcela Maslanova)
• When computing the SHA1 in par_mktmpdir (myldr/mktmpdir.c) rewind file descriptor f first. Otherwise we checksum just the last 12 bytes of file progname. (Roderich)
• RT #18472: "parl foo.par script.pl ..." uses a cache area that doesn't depend on foo.par Indeed, the (name of) the cache area used for "parl foo.par ..." is derived from the SHA1 checksum of parl.exe, and not foo.par. This patch changes that for the common use case above. It is not a complete fix though, as this would require to parse the parl command line arguments on the C level. (Roderich)

[Changes for 0.992_04 - Sep 11, 2009]
* New features

• Reject "main.pl" as input scripts since this can override the bootstrapping code. For wizards who really want this, there should be still "-a main.pl;script/main.pl".
  • Bug fixes, etc.
• Fix RT #48614: ignore setting of PERL5OPT (and others) in a packed executable (Roderich)
• Fix RT #48027: Fix building with ActivePerl & MinGW

[Changes for 0.992_03 - Jul 24, 2009]
* Bug fixes, etc.

• Fix "Can't locate IO/file.pm in @INC ..." bug (Markus Jansen)

[Changes for 0.992_02 - Jul 23, 2009]
* New features

• Add the cachedeps option to pp: PAR::Packer can now use the new Module::ScanDeps feature of caching the module dependencies for a significant packaging speed-up.

[Changes for 0.992_01 - Jul 19, 2009]
* New features

• Reusable pp packaged applications (see pp's --reusable option)
  • Bug fixes, etc.
• Accept other extensions than .par in -p mode.

[Changes for 0.991 - Mar 21, 2009]
* New features

• Add Roderich's reeally useful debugging tool "extract_embedded.pl" to the contrib/ subdirectory. It can be used to extract the contents of a "parl" binary.
  • Bug fixes, etc.
• Add Errno and Tie::Hash::NamedCapture (if available) to required_modules
• Fix the stripping of =encoding POD lines in PAR::Filter::PodStrip
• Throw a proper error if a module specified via -M cannot be found (Roderich Schupp, Gabor Szabo)
• Don't update exe's with icons twice on Win32.
• Band-aid fix for RT #41790 in par.pl
• Some very slightly more careful handling of environment variables in par.pl
• Fix SEGV crash during startup if $PATH is not defined (Johannes Lode)
  • Documentation
• RT #12104. Improved documentation in pp on -T/--tempcache.

[Changes for 0.982 - Jul 29, 2008]
* Bug fixes, etc.

• Fix bleadperl compilation.
• Ensure extracted files are marked executable on HP-UX so they can be used by the dynamic linker. (Scott Stanton)
• Fixed incorrect error handling code in test for directory existence when creating a private temporary directory. (Scott Stanton)
• On Windows, attempt to use the system temp directory before trying the temp_dirs locations. (Scott Stanton)
• Don't remove the top level par-<user> directory for PAR_CLEAN=1 because doing so introduces a race condition with other applications trying to create the directory on startup. (Scott Stanton)
• When creating the temporary directory for PAR_CLEAN=1, ensure that the directory does not already exist to avoid picking up stale files from a prior invocation of a different par application. This eliminates the need to rename the temp directory before removing it, which was causing race conditions in multi-threaded apps. (Scott Stanton)
• Now officially requires Perl 5.6.1 and up in the Makefile.PL. This has been the case for a long time anyway, but this change should suppress some spurious CPAN testers failures.
  • Documentation
• Clarified examples in the pp documentation, thanks to Dave Howorth.

[Changes for 0.981 - May 14, 2008]
* Bug fixes, etc.

• Make get_username_from_getpwuid work for uid=0. (Scott Stanton)
• Fixed crash in get_username_from_getpwuid when getpwuid fails. (Scott Stanton)
• Fix broken build on win32 when searching for dll and finding static perl library. (Alexey Borzenkov)
• Fix compilation on MacOS 10.5's gcc because that doesn't seem to support the --output option. (Matthew Andersen)

[Changes for 0.980 - May 14, 2008]
* Emergency bug fix release

• The test suite in the previous release was broken by my debugging code. Sorry about that. (Steffen)

[Changes for 0.979 - May 13, 2008]
* Bug fixes, etc.

• Add a preprocessor conditional to myldr/internals.c to make PAR::Packer compile with blead (Avar Bjarmason, Nicholas Clark)
• Also strip =encoding POD directive during PAR::Filter::PodStrip.
• Temporarily disable the shared-libraries cleanup code in par.pl that was introduced in 0.977 by Scott. This may result in stale cache directories even if PAR_CLEAN is in effect. On the other hand, this means threaded applications work again.

[Changes for 0.978 - Feb 28, 2008]

• Bug fixes, etc.
  • Fix pp -r for absolute file names (RT #33355) (Slaven Rezic)
  • Fix for FreeBSD's unreliable procfs (RT #33349) (Slaven Rezic)
  • Fix @INC ordering in par.pl:This might just fix the infamous "Only available with the XS version..." bug (see #24192) (Michael Schwern, Slaven Rezic)
  • Fix pp.pm version (Audrey)
  • Require Win32::Process on win32 (Audrey)
  • The parl-generation tests are now skipped if a pre-built .par binary is being used. (Mark Dootson)
  • Shared library extraction now checks first whether the file exists and whether it has the same size as the one to be extracted. In that case, the extraction is skipped. This should fix an issue with overwriting DLLs on Windows, see http://www.nntp.perl.org/group/perl.par/3325 (Scott Stanton)
  • When re-building the distribution because of a change in e.g. script/par.pl, the DATA sections of blib\PAR\StrippedPARL\{Dynamic,Static}.pm were not updated accordingly.

[Changes for 0.977 - Dec 20, 2007]

• New features
  • Support for Perl 5.10 and later.
  • New -E flag for "pp" that works just like "perl -E" for Perl 5.10+, namely enabling new syntactic features like "say".
• Bug fixes, etc.
  • When deleting the temp directory in the background, rename the directory to a unique name to avoid potential collisions caused by pid reuse (primarily an issue on Windows).
  • PAR::Packer now depends on Module::ScanDeps 0.78 because 0.77 had a critical bug. If you are having trouble with M::SD 0.78, please a) report it in the bug tracker and b) try versions of M::SD below 0.77.
  • If running with the "clean" option, go through extra pain in par.pl to clean up if the OS doesn't allow opened shared libraries to be deleted. (Scott Stanton)
  • Use the P_tmpdir macro as temporary directory on Unix if available. See RT #29784.
  • Included PWD fix. See RT #29050.
  • Added deletion of 'orig_parl' on Win32 in PAR::Packer.

[Changes for 0.976 - Jul 29, 2007]
* New features

• If available, the packager will include the new and slightly experimental Archive::Unzip::Burst module in generated binary executables. This can speed up the initial extraction of such a binary by a significant factor. (Total running time went from 8 seconds to 1.4 seconds in a simplistic test.)
• The preprocessor option/define PERL_PROFILING can be used while compiling myldr/ (parl) to enable Devel::DProf profiling of the archive extraction.
  • Bug fixes, etc.
• myldr/Makefile workaround for HPUX. (RT #24950)
• Makefile.PL doesn't require 5.006 any more but uses 'strict' now.
• Makefile.PL doesn't use Module::AutoInstall any more. It's evil.
• Dependency on PAR.pm upgraded to 0.976.
• Marked PAR::Filter::Bytecode as deprecated. Added references to PAR::Filter::Crypto.

[Changes for 0.975 - May 06, 2007]
* Bug fixes, etc.

• Trailing backslashes in @INC paths handled in PAR::StrippedParl::Base
• Win32 added to 'required modules' to handle changes in Win32 core present in ActiveState build 820 and development branches.
• No longer assume -B when using pp -P (or -p). (Roderich Schupp)

[Changes for 0.973 - Feb 3, 2007]
* New features

• If PERL5LIB is set, that variable may be ignored in some parts of the myldr/ build process. We now warn the user during Makefile.PL if PERL5LIB is set. (Gaal Yahas)
  • Bug fixes, etc.
• Cosmetics: Add "use strict;" and "use warnings;" to some files that lacked it.
• Several bug fixes for the tests from Malcolm Nooning. Related to making them work on Windows with spaces in paths.
• Added regexp escaping to the "pp -X foo.par" use case. (Eric Wilhelm)

[Changes for 0.970 - Dec 3, 2006]
* This is the first release of PAR-Packer as a separate distribution. * PAR and PAR-Packer (+pp, parl, etc.) have been separated because there is usually no reason for the PAR Packager to be present on a user system which just needs PAR.pm to access .par archives. * PAR-Packer will include all development tools such as those included in the contrib/ subdirectory.

• Bug fixes, etc.
  • Moved most code from script/pp to lib/pp.pm so it gets picked up by the CPAN indexer. Hence you will be able to write "install pp" in the CPAN shell to install pp/PAR::Packer.
  • PAR::StrippedPARL::Base->write_parl() failed to work if the @INC directories contained spaces in 0.960. (Steven Mackenzie)
  • Much improved documentation of the environment variables (Glenn Linderman)
  • Fix for a spaces-in-pathname problem on Windows for t/30-current_exec.t. (Malcolm Nooning)

[Changes for 0.960 - Nov 21, 2006]
* Bug fixes, etc.

• myldr/Makefile.PL fix: Clean up myldr/usernamefrompwuid.h.
• Silence warning in myldr/internals.c.
• Silence warnings seen on Irix from myldr/env.c.
• Skip most tests in 10-parl-generation.t if there is no parl.
• Skip loading ActiveState Perl's "sitecustomize.pl" in par.pl.
• Load modules via require and other files via do.
• The parl-regeneration-for-every-pp-call addition of the 0.958 release should now also work for static perls.
  • New features
• Adressing RT ticket #6612: Now using getpwuid() to determine the user name if supported by the OS.

[Changes for 0.959 - Nov 12, 2006]
* This is just a hotfix release because 0.958 lacked META.yml. One day, I will switch from Module::Install to Module::Build...

[Changes for 0.958 - Oct 25, 2006]
* Bug fixes, etc.

• myldr/Makefile.PL fix: make static.o depend on mktmpdir.c, my_perl.c, my_par.c. (Roderich Schupp)
• Modules included with the -M option to pp were previously scanned for dependencies but not mapped through the %Module::ScanDeps::Preload hash for custom dependencies. That's fixed now.
• $ENV{PAR_RUN} isn't set by PAR::Packer any more because nothing in the PAR sources uses it. $ENV{PAR_RUN} is no longer used by PAR at all.
• Unified the environment variables which are looked at for finding the system's temporary directory.
  • New features
• During the build process, PAR appends stripped down copies of parl (and parldyn if applicable) to the data classes PAR::StrippedPARL::Static and ::Dynamic. These parls-without-embedded-modules are used for packaging so the formerly embedded modules are now packaged from the packaging system. (Instead of stemming from the system where PAR/parl was built.)
• The "use PAR { repository => $url };" syntax now also supports the use of user-constructed PAR::Repository::Client objects instead of an URL.
• The -F (module code filter) option now supports selective filtering of modules. The syntax is "-F FILTER=REGEX" or - as before - "-F FILTER". The regular expression is applied to the file name, of the module inside the PAR (e.g. Foo/Bar.pm). This behaviour was chosen over matching against the module name (e.g. Foo::Bar) because the filters can be applied to module-like and script files as well (.pl, .al, etc.).
• Updated PAR/FAQ.pod with the new FAQ's from the PAR wiki.
• Added a POD file PAR/Environment.pod which is intended to become an index of all environment variables PAR uses of its own or recognizes from its users. Still mostly a stub.

[Changes for 0.957 - Oct 24, 2006]
* Bug fixes, etc.

• Fix executable PARs top properly detect embedded scripts named the same as the executable. (Jesse Vincent)
• Comment out the call to par_current_exec_proc (in the C loader) which breaks the use of symlinks to pp-ed executables when not called with a path. (I.e. using a search in $PATH).

[Changes for 0.956 - Oct 3, 2006]
* This is another hotfix release. Fixed a mindless bug introduced in 0.955.

[Changes for 0.955 - Oct 3, 2006]
* Bug fixes, etc.

• 0.952 introduced removal of system module search paths if -B is in effect. This resulted in some valid PAR-related paths being removed as well. Fixed. Upgrading from 0.952 and 0.954 is suggested.
• Changed the use of hard-coded '/' as path-separator to using File::Spec.

[Changes for 0.954 - Sep 26, 2006]
* This release is equivalent to 0.953. The 0.953 CPAN upload is broken!

[Changes for 0.953 - Sep 18, 2006]
* Bug fixes, etc.

• Added optional POD tests.
• Modified -B so that if -B is in effect, all entries are stripped out of @INC except for the PAR hooks. This happens right before the script contained in the pp-ed binary is executed.

[Changes for 0.952 - Aug 22, 2006]

• New features
  • Added the "install" option to the PAR loading syntax. If specified, the contents of the PAR distribution are permanently installed. This requires PAR::Repository::Client 0.04.
• Bug fixes, etc.
  • Fixed broken META.yml in 0.951.

[Changes for 0.951 - Aug 12, 2006]
(This includes any changes up to 0.950.)

• New features
  • Introduced new PAR loading syntax and semantics: use PAR { file => 'path/to/par/or/URL' }; ==> equivalent to "use PAR 'path/to/par/or/URL';"
  • Introduced the 'fallback' option: (default = 0) use PAR { file => 'foo.par', fallback => 1 }; ==> Loads modules from the PAR file only if loading

    them from @INC did not succeed.

  • Introduced the 'run' option which executes a script in a PAR archive just like perl -MPAR foo.par script.pl
  • If PAR::Repository::Client is installed, you can add a repository of .par distributions to your library search path as follows: use PAR { repository => 'http://foo' };
  • Of course, 'run' also works with repositories: use PAR { repository => 'http://foo', run => 'my_app' }; (This searches the repository for any distributions that have a my_app script.) --> For details on repositories, have a look at the

    PAR::Repository::Client module.

    • Bug fixes, etc.
  • Commented a couple of the routines in PAR.pm. (Yay!)
  • New test script for the new fallback loading feature.
  • Fixed a bug in the Spreadsheet::ParseExcel handling in PatchContent.pm.

[Changes for 0.942 - Jul 22, 2006]

• Bug fixes, etc.
  • Better support for diagnostics.pm (in conjunction with Module::ScanDeps 0.62.)
  • Now requiring Module::ScanDeps 0.62.

[Changes for 0.941 - Jun 20, 2006]
(No, PAR isn't stagnating. It's just that 1.00 would draw close if we continued with 0.01 increases.)

• Bug fixes, etc.
  • Version 0.94 of PAR would use the same cache area for all pp-ed applications due to a faulty hotfix for Digest::SHA. This applies to PAR 0.94 only. Think of 0.941 being PAR 0.94 done right.

[Changes for 0.94 - Jun 1, 2006]

• New Features
  • Added support for reading options to pp from a file using a '@filename' argument to pp: pp -o foo --gui @filename foo.pl
• Bug fixes, etc.
  • Workaround for a bug in Digest::SHA 5.38 and 5.39 that would prevent PAR from being built.
  • Fixed details in the 2-pp.t test file.
  • Now recognizes text files that aren't picked up by the -T operator but by the "file" tool.
  • Applied Roderich Schupp's patch to 30-current_exec.t to fix a path issue.
  • Now requiring Module::ScanDeps 0.60 which fixes a couple of bugs which might be observed as PAR bugs.
  • Now working well with Spreadsheet::ParseExcel which uses an invalid POD section to comment out a code block. This wasn't recognized by PAR::Filter::PodStrip as POD and hence partly left in...
  • If the output directory doesn't exist, we create it now and output a meaningful error message if that failed.

[Changes for 0.93 - May 19, 2006]

• New Features
  • Added support for PAR_TMPDIR (PAR_GLOBAL_TMPDIR) so that the temp directory can be controlled for just the PAR file bits. (Leolo)
  • Added par_current_exec_proc() which finds the file of the current executable in /proc, if possible. (Leolo)
  • Added par_current_exec() which finds he file of the current executable, if possible on this OS. (Leolo)
  • par_findprog() now uses par_current_exec() if possible.
• Bug Fixes, etc.
  • Upgraded to Module::Install 0.62+ (Audrey Tang, Steffen Mueller)
  • Document a strange interaction with chdir() and relative paths. (Chris Dolan)
  • Documented the bits that make up PAR_TEMP. (Leolo)
  • Fixed the call to par_findprog. path (aka val) was set to tmpdir. (Leolo)
  • Documented the CACHE name at the end of a self-executing PAR. (Leolo)
  • myldr/Makefile.PL now generates some dependencies for main.c (Leolo)
  • Applied patch from RT ticket. (tsee) https://rt.cpan.org/Ticket/Display.html?id=13959
  • Applied Ivan Kudryavtsev's patch that fixes a couple of calls to PAR subroutines in PatchContent filtered code. (tsee)

[Changes for 0.92 - February 22, 2006]

• Bug Fixes
  • Now requiring Module::ScanDeps 0.56 which handles autouse correctly.
  • Now shipping with a correct SIGNATURE. (Which was broken for 0.91.)

[Changes for 0.91 - February 13, 2006]

• Bug Fixes
  • Applied Alan Stewart's patch which fixes @ARGV pollution in daughter programs. See also http://www.nntp.perl.org/group/perl.par/2152
  • Now mentioning the ENV var "PAR_VERBATIM" in the documentation. See also http://www.nntp.perl.org/group/perl.par/2196
  • Applied Malcolm Nooning's fix for the test suite. We used to get failed tests on Windows because of spaces in path names.
  • Applied Roderich Schupp's and Malcolm Nooning's patches to the test suite fixing problems with Cygwin.
  • Applied Vincent Ladeuil's patch to PAR::Filter::Bleach to return a true value for modules that loaded okay.
  • Changed 'PAR_BASE' in the Makefile.PL to 'SMUELLER'.

[Changes for 0.90 - November 25, 2005]

• Bug Fixes
  • When compiling with static libperl, myldr/ may fail "make" due to sha1.c not generated properly.
  • Pod stripping could fail on __DATA__ sections for files with CRLF line endings.
  • The documentation erroneously referred to the PAR_TEMP environment variable, whereas it should be PAR_GLOBAL_TEMP.
  • Compilation fixes for MinGW/MSYS.

[Changes for 0.89 - June 10, 2005]

• Bug Fixes
  • Stop static.c from pulling in Perl header files, otherwise parl.exe ends up depending on the Perl DLL on Win32 when Perl is built without PERL_IMPLICIT_SYS.
  • With *nix and File::Path 1.06, par.pl's avoidance of loading Cwd.pm caused syntax errors.

[Changes for 0.88 - June 7, 2005]

• Bug Fixes
  • Extracted .pl files should be loadable via the coderef-in-@INC too, just like .pm files and autosplit files. This makes PAR work with Perl 5.8.7 on Win32.
  • Fix the build with GCC 4.0.
  • If $ENV{PWD} is not defined, fallback to use `pwd` to obtain the working directory for invoking.

[Changes for 0.87 - January 31, 2005]

• Bug Fixes
  • On Win32, some versions of File::Spec::Win32 contains explicit "use Cwd;" lines, which renders parl.exe unusable.
  • Executable made by "pp" may fail when invoked as "./a.out" or "../a.out", due to incorrect PWD handling logic.

[Changes for 0.86 - December 11, 2004]

• New Features
  • New "pp -z" (--compress) option to set compression level (0-9).
  • New "pp -T" (--tempcache) option to override the per-executable directory name; it defaults to a hash of the executable, computed at compile time. This makes startup much faster for large executables.
  • The hash algorithm described above now prefers Digest::SHA if installed, otherwise Digest::SHA1, then fallbacks to Digest::MD5.
  • Functionality of "pp -X" is now extended: if the argument after -X is a zip or par file, files in it are excluded from the produced executable, and the executable will "use" the zip/par instead. For multiple -X args, successive args are only "use"d if they contain additional unique files.
  • "pp -l" now searches for libraries in "." and PATH in Win32.
  • "pp -l" shared libraries are now added to %skip, so it will not be included in both shlib/ and lib/.
  • "pp -l" now chases symbolic links. For example, if "libsomelib.so" is a symlink to "libsomelib.so.1", which is another symlink to "libsomelib.so.1.2", pp now follows these symlinks and add the real file the par, rather than "libsomelib.so".
  • New contributed code in "contrib/stdio/": Useful Tk console for "pp -g" users.
  • New contributed tutorial documents, currently in "contrib/docs/", which will eventually be turned into POD documents.
  • Running "perl Makefile.PL" with $ENV{DEBUG} set to true now produces "parl" with debug symbols.
  • Remove Cwd.pm (and Cwd.so) from the bundled dependencies.
• Bug Fixes
  • More robust probing for case-insensitive file systems.
  • PodStrip now attempts to match "standard" pod start before =cut, otherwise =cut gets removed by itself.
  • Win32 slashes are now normalized in privlib and archlib directories.
  • Don't extract shared libraries to inc/, since they were extracted in $PAR_TEMP already.
  • Don't re-extract shared libraries in subdirectories, since they are picked up by corresponding "use".
  • Tk now exits properly with a non-zero exit() value.
  • Fix libperl probing problem on Debian and Gentoo that manifests as a "libperl5.8.so not found" error during runtime.
  • gpp: Fixed typo in options with multiple filenames; cleaned up pp parameters.
  • When PAR_TEMP is set, shlib/ was not correctly added to the dynamic load path environment variables.
  • PAR now builds with Win32 VC++ without CVTRES.EXE available.
  • Detection of cl.exe, gcc.exe and cc.exe is now case-insensitive.

[Changes for 0.85 - July 2, 2004]

• New Features
  • New version of "gpp"; see contrib/gui_pp/gpp_readme.txt for details.
• Bug Fixes
  • MANIFEST and META.yml were not properly updated by PAR::Packer.
  • Setting directory aliases with "pp -a"/"pp -A" was broken. Fixed, and tests were added for it.
  • Statically-built executables was needlessly extracting libperl each time it runs; now it is eliminated and hence much faster.

[Changes for 0.83 - May 29, 2004]

• New Features
  • Revamped PAR::FAQ and sychronized with par.perl.org.
  • In pp-generated programs, $0 is now set to the pathname leading to the invoked executable. Use $ENV{PAR_0} instead to get the filename that contains the main perl program.
  • Updated "contrib/gui_pp/gpp" to support PAR::Packer options.
• Bug Fixes
  • Core XS modules, such as Data::Dumper, were skipped by "pp".
  • Fix t/2-pp.t for Cygwin by probing $Config{_exe} rather than uname().
  • Scripts made by "pp -P", when invoked as "perl scriptname", should not search for the same-named programs in PATH.
  • Correctly remove leading slash and drive letters from absolute filenames passed to "pp -a". Also normalized blackslahes to slashes.
  • The PP_OPTS environment variable was not recognized.
  • "pp -a dirname;diralias" was broken.
  • "pp -f" and "pp -F" were broken.

[Changes for 0.82 - May 24, 2004]

• New Features
  • New module PAR::Packer provides an OO interface to "pp"'s functionality; "pp" is now merely a thin wrapper for it.
  • New module App::Packer::PAR is a modified version of App::Packer, designed to work with PAR::Packer, and will hopefully be merged back to App::Packer.
  • The old, procedural "pp" is moved to contrib/; end-users should notice no changes in "pp"'s behaviour.
  • New options "pp -a" and "pp -A" (--addfile/--addlist) provides ways to include extra files and directories in the package.
  • The long option name for "pp -M" is changed from --add to --module. The old name is still recognized but no longer documented. Using "pp -M" to include non-library files is now deprecated; use "pp -a" instead.
  • par.pl and parl now writes messages to STDOUT, instead of STDERR. As a consequence, t/2-pp.t no longer prints extra warnings during "make test".
• Bug Fixes
  • On Non-Win32 platforms, perl 5.8.0 and earlier versions produced pp-generated executables that immediately segfaults.
  • Running pp-generated executables with absolute pathname failed on statically-built perls.
  • Tests were failing due to a missing pipeacommand.pm in MANIFEST.
  • Add the missing myldr/win32.coff for building on Cygwin/MinGW.
  • If the "perl" in path is different from the perl interpreter used for "make test", t/2-pp.t is known to fail and is now skipped.
  • Cygwin failed t/2-pp.t because "parl" is spelled as "parl.exe" there.

[Changes for 0.81 - May 23, 2004]

• New Features
  • Regained support for Win9x, Cygwin and MinGW.
  • PAR now supports 64-bit platforms, such as Tru64 and AIX.
  • Cygwin and MinGW can now build EXEs with icons, too; MinGW can update the icons, but Cygwin cannot.
  • Newly supported modules: Pod::Usage, DBIx::SearchBuilder, DBIx::ReportBuilder, SVK::Command, SVN::Core, and the ':encoding()' IO discipline.
• Bug Fixes
  • On non-Win32 systems, invoking pp-generated executable from PATH did not work.
  • Standalone executables were clobbered by existing perl environments with an identical "auto/IO" libpath as the author's environment.
  • Standalone executables did not work on systems with an unset dynamic load path environment variable (eg. LD_LIBRARY_PATH).
  • "pp -p -o multi.par 1.pl 2.pl; parl multi.par 1.pl" now works.
  • $ENV{PATH} and $ENV{TEMP} were truncated at first path delimiter.
  • "pp -f Bleach" did not work for ActivePerl on Win32.
  • Windows 9x systems were generating invalid cache directory names.
  • $ENV{path} is also recognized as $ENV{PATH} for Win32.

[Changes for 0.80 - March 17, 2004]

• New Features
  • A comprehensive test suite for pp in contrib/automated_pp_test/. It is run as part of the "make test" process from t/2-pp.t.
  • Much better support for "pp -i" and "pp -N" (--icon/--info) using the Win32::Exe module. You may now use EXE and DLL as icon files.
  • If PAR_GLOBAL_CLEAN (-C, --clean) is not set, we now preemptively extracts files under the cache directory. That made POSIX.pm and other modules that depends on %INC pointing to real files work correctly.
  • Now uses SHA-1 to create temporary directories and files, instead of mtime.
  • Verbosity level is now 1..3, not 0..5; "pp -v" now takes an optional integer, so "pp -v input.pl" is no longer an error.
  • New flags "-vv" and "-vvv", as shorthands for "-v 2" and "-v 3".
  • The user-settable PAR_CLEAN and PAR_TEMP environment variables has been renamed to PAR_GLOBAL_CLEAN and PAR_GLOBAL_TEMP; the original variables are still accessible within the program. This is so that a pp-generated program can exec() or system() another one without crippling its environment variables.
  • File lookups are now case-insensitive on case-insensitive filesystems.
  • Another Tk-based GUI in contrib/gui_pp/; not installed by default.
  • OOified "pp" in contrib/object_oriented_pp/; not installed by default.
• Bug Fixes
  • "pp -d" (--dependent) prevented "pp -C" (--clean) from working.
  • The "pp -m" (--multiarch) option was implemented incorrectly and thus broken.
  • Many documentation tweaks.
  • Previously, "pp -M" (--module) did not add the module itself, only its dependencies.
  • Suppress a bogus warning when $ENV{$Config{ldlibpthname}} is empty.
  • "parl -v" without Module::Signature installed could delete all files within the current directory. Oops.
  • On *nix systems, pp-generated executables erroneously linked to libperl even if "pp -d" (--dependent) is not set.
  • Spurious =cut directives in source files is now handled gracefully by PAR::Filter::PodStrip.
  • "pp -L" (--log) now logs all output messages to the log file, not just the ones printed by "pp" itself.

[Changes for 0.79 - January 8, 2004]

• Bug Fixes
  • Setting PAR_CLEAN had the reversed effect. Oops.
  • Dynamic libraries in cached directories was not detected properly, resulting in "permission denied" errors during certain race conditions.

[Changes for 0.78 - January 7, 2004]

• New Features
  • By default, executables generated by "pp" will now store extracted files in cache directories. You may override this by setting the PAR_CLEAN environment variable to "1", or generate executables using "pp -C".
  • New "pp -C" (--clean) option to make the generated executable clean up temporary directories after each run.
  • PAR_CLEARTEMP is renamed to PAR_CLEAN.
• Bug Fixes
  • On Win32, temporary directories containing shared libraries was not being properly cleaned up.
  • If no suitable temporary directories are found, use the current directory (".") instead of the root directory ("/").

[Changes for 0.77 - January 1, 2004]

• New Features
  • New "pp -c" and "pp -x" (--compile/--execute) options run the script with "perl -c" to check for dependencies.
  • Also, the new "pp -n" (--noscan) command skips the default static scanning altogether.
  • Added support for "pp -c/-x/-n" to tkpp.
  • For dynamically-built perls, pp-generated .exe files will now appear in the process table with the same name as it was launched, instead of "par.exe".
  • New filter "Obfuscate", which uses B::Deobfuscate to strip away PODs and comments, as well as mangling variable names.
  • Merged tkpp 1.1 from Doug Gruber.
  • OS/2 is now supported.
  • External Zlib is no longer required to run pp-generated binaries.
• Bug Fixes
  • Makefile.PL was failing if $Config{cc} contains spaces.
  • No longer needs setting "Windows 95 compatible mode" to run on WinXP.
  • On Win9x with Perl 5.6.1, "nmake" was failing due to extra "@[...]" symbols in Makefile. It should be fixed now.
  • The "bad signature" problem with newer Archive::Zip versions is fixed.
  • App::Packer::Backend::PAR was misplaced into App/Packer/PAR.
  • Signature tests were failing under new ExtUtils::MakeMaker versions.
  • ActiveState's PPM building machine was having problem with PAR; a ".pdb" entry in MANIFEST.SKIP is added to fix that.
  • Some self-built PAR instances on Windows were failing due to mismatching short and long pathnames.

[Changes for 0.76 - October 28, 2003]

• New Features
  • Input filters. "pp --filter Bleach" now obfuscates the incoming script with PAR::Filter::Bleach; "pp --modfilter Bleach" applies Bleach to all packed modules.
  • Two previously built-in filters, PodStrip and PatchContent, are refactored out as PAR::Filter subclasses.
  • Two new filters, Bleach and Bytecode, are added for source-hiding purporses.
  • New utility, "tkpp", provides a GUI frontend to "pp".
  • New option, "pp --perlscript", to generate stand-alone scripts.
  • The old "PAR::Intro" documentation has been replaced by two new ones: "PAR::Tutorial" and "PAR::FAQ".
  • Tk pixmap (.xpm) files can now be packed with "pp --add".
• Bug Fixes
  • Perl 5.8.1 has an off-by-one bug that prevents "parl" to function properly. We have now provided a workaround; this bug should also be fixed in Perl 5.8.2.
  • Fixed https support for LWP via the new Module::ScapDeps.

[Changes for 0.75 - September 21, 2003]

• New Features
  • "pp -o file.exe file.par" now packs file.par into file.exe; this means you can hand-tweak PAR files generated by "pp -p" before packing it into an executable.
• Bug Fixes
  • Packing multiple programs by "pp script1.pl script2.pl" was producing syntax errors; fixed.
  • "pp -M datafile" now works.
  • Exit code from pp-packed executables now properly propagates out.
  • Fixed "use base" detection, Math::BigInt support and spurious signature warnings, by updated versions of Module::ScapDeps and Module::Signature.
  • On Win32, the PE info headers no longer show PAR_XXXXXXXXXXX.

[Changes for 0.74 - August 20, 2003]

• New Features
  • pp now has a set of "PatchContent" rules, dealing with non-PAR-compatible modules: Tk, Tk::Widget, Win32::API::Type, Win32::SystemInfo, SQL::Parser, diagnostics. These rules may get refactored back to PAR.pm in the future.
  • New function, PAR::reload_libs(), to reload currently used libraries inside PAR files.
  • PAR.pm itself is now never packed into pp-generated files, to perserve interface compatibility and reduce bloat.
  • PAR.pm now handles "use PAR 'othercode.par'" called from program or modules inside PAR files, even recursively.
  • A new icon for Win32 that is hopefully prettier.
• Bug Fixes
  • All data after __DATA__ are preserved for included libraries. This helps self-reading modules like Net::LDAP::Constants.
  • PAR::read_file() was broken. It now works.
  • "use PAR" inside pp-generated executables was failing with 'file too short' errors due the mishandling of seek/tell.
  • Occasional crashes on Win32 due to rmdir() called too early with DLLs still open is fixed; however, "pp -d" executables may still exhibit this problem.
  • "pp -X" used to only take full pathnames as arguments. It now also takes "Module::Name" and "Module/Name.pm".
  • Dynamically built Perl under Cygwin failed to build, because libperl.dll.a was not found.
  • Eliminated "callback called on exit" warnings, and the related "access violation" error on Win32.

[Changes for 0.73 - August 6, 2003]

• New Features
  • The PAR Homepage is now online at http://par.perl.org/. Documentations have been changed to link to it.
• Bug Fixes
  • Tk applications can now properly access xpm/xbm files with Tk->findINC.
  • On Win32, pp-generated executables could not start from Explorer, if its path contains space characters. Fixed.
  • On Win32, pp-generated executables used to leave around an empty directory in $ENV{TEMP}. It is now properly rmdir'ed.
  • Some systems (notably OpenBSD and Debian) does not put their libperl.so in the default location, which breaks the build process; now searches inside $ENV{$Config{ldlibpthname}} and $Config{libpth} to find it.

[Changes for 0.72 - August 2, 2003]

• New Features
  • CHECK and INIT blocks in programs inside PAR are now supported.
• Bug Fixes
  • Two debug statements were mistakenly left in the source, resulting in "trying to get rid of /tmp/par_priv.xxxx.tmp" messages.
  • Building on Linux with GCC 3.2.2 was failing due to massive heap required for my_perl.c. Fixed by splitting it into 3k chunks.
  • Depends on Module::ScanDeps 0.21; it supports utf8 on Perl 5.6.1 and can significantly reduce executable file size by eliminating unneccessary shared libraries.

[Changes for 0.71 - July 30, 2003]

• Bug Fixes
  • A nasty data-loss bug has been uncovered immediately after the previous release; it only affects Windows platforms, and may cause all files to be erased under the current root (\) directory.
  • Building on Red Hat linux was failing, with error message that says "my_perl not declared". This has since been fixed.

[Changes for 0.70 - July 29, 2003]

• New Features
  • On machines with shared libperl, "pp" now makes truly stand-alone executables; the old behaviour is available with "pp --dependent".
  • Under Windows NT/2000/XP, "pp --icon=name.ico" now changes the icon for the generated executable; otherwise, a default "white camel" icon is used.
  • "use PAR 'http://example.com/foo.par'" now works, as does "perl -MPAR -Ihttp://example.com/foo.par".
  • PAR::Dist is now a mandatory prerequisite, which provides functions to turn any CPAN distribution into a PAR distribution, as well as to install, uninstall, sign and verify such files.
  • Integrated PAR::Dist into "par.pl" and "parl". For example, "parl -i Foo-0.01-i386-freebsd-5.8.0.par" installs a PAR distribution; "parl -v out.exe" verifies a digitally signed executable generated by "pp --sign".
  • A new option, "pp --multiarch", lets you generate PAR files that can work on several architectures.
  • "pp --sign" now adds digital signatures to generated executables and PAR files.
  • PAR files may now (recursively) contain other PAR files inside their par/ directories.
  • shlib/ and par/ directories inside PAR files can now contain architecture- and perl-version-specific subdirectories.
  • The "Cross-Platform Packaging and Deployment with PAR" tutorial is now online as http://www.autrijus.org/par-tutorial/.
• Bug Fixes
  • MANIFEST.SKIP was broken on Win32.
  • C compilers that doesn't handle long line well can now compile PAR.
  • DLL files inside the same auto/ library as XS modules was not properly extracted and loaded. This specifically affects Win32.
  • Because parl's @INC is '.', pp-generated executables may miss IO.dll and other shared libraries since they couldn't be correctly found in @INC.

[Changes for 0.69 - May 31, 2003]

• New Features
  • Under Perl 5.8, "pp -p" now works with Apache::PAR. See http://aut.dyndns.org/par-tutorial/slide018.html for a simple example.
  • "pp -M filename" now adds "filename" to /, not /lib/, unless filename ends in (pm|ix|al). This makes it possible to bundle "web.conf" needed by Apache::PAR.
  • "pp -l" now searchs in system library paths, and appends "lib" / prepends ".$dl_ext" where necessary.
• Bug Fixes
  • PAR segfaults on some Unix platforms due to a NULL pointer used in mktmpdir.c. Fixed.
  • "pp -o out.par -p -e '...'" now honors -o; previously it used "a.out.par" anyway.
  • Inhibited spurious uninitialized warnings under -w in the POD-stripping code.
  • Win32 did not properly cleans up PAR_TEMP directory, resulting in failure for executables that reused the same PID. Fixed.

[Changes for 0.68 - May 26, 2003]

• New Features
  • New 'pp -l' option to pack additional shared libraries (DLLs).
  • POD-stripped libraries inside PAR files now have #line directives inserted, so they report the original line numbers on failure.
  • PAR files generated by 'pp' now has a MANIFEST file that can be viewed by Gecko-based browsers with Javascript turned on, e.g.: jar:http://aut.dyndns.org/par/test.par!/MANIFEST
• Bug Fixes
  • Each pp-executable instance now creates its own PAR_TEMP directory; this avoids permission errors when multiple users run the same binary. As a consequence, PAR_CLEARTEMP is now set to "1" by default.
  • Newer versions of shared Zlib library no longer causes "pp" to generate broken executables.
  • Fixed dynamic loading on Cygwin was failing due to missing +x mode.
  • Like "use lib", "use PAR 'name.par'" now unshift()s instead of push()es into @INC. Same applies for "par.pl -A" and "parl -A".
  • Fixed building on ActivePerl 626 and below due to a missing $Config{ld}.

[Changes for 0.67 - April 1, 2003]

• New Features
  • PAR now works on Cygwin and MinGW/MSYS.
  • Globbing support in PAR::import(): use PAR "/path/*.pm";
  • New license clarification messages added to POD and 'pp -V'.
  • All 'pp' options now has a short form (-o) and a long form (--output).
  • Revamped documentation for 'pp'.
  • New -g (--gui) flag for 'pp' to build console-less Win32 executables.
• Bug Fixes
  • Building on Darwin Perl 5.6.0 was broken with 'cc -s'.
  • Building on 5.6.0 was broken due to bad 'base.pm'.
  • Win32 Tk::Widget autoloading was broken due to a binmode() bug.
  • IPC::Run was pod-stripped incorrectly. Fixed.
  • Depends on Module::ScanDeps 0.19, which supports utf8 and .ph files.
  • Better AutoInstall support, which uses 'sudo' where necessary.

[Changes for 0.66 - March 20, 2003]

• New Features
  • Adds PAR::Intro, a PODified version of the online presentation.
  • Adds App::Packer::Backend::PAR, a bridge between PAR and App::Packer.
  • Scripts and modules are now searched in "/" last, instead of first.
  • Experimental patch for packing shared libraries via "pp -l".
  • HTTP fetching of precompiled packages in addition to FTP.
• Bug Fixes
  • Makefile.PL now downloads precompiled packages only if needed.
  • AutoInstall has been made to work for an easier installation.
  • The redundant "parl.exe.bat" is no longer created on Win32.
  • Pre-0.63 PARs used to leave broken .dll in TEMP; now they're cleaned.
  • "pp c:\something.pl" no longer treats c: as a relative path.
  • "pp -I dir" now searches 'dir' first, instead of last.
  • "pp" was broken on Perl 5.6.0 due to => stringification bugs.
  • Support for Tk::Widget autoloading has been added.
  • "parl" was not stripped if "gcc" was invoked as "cc"; fixed.
  • On a machine with multiple "parl"s, "pp" now uses the correct one.
  • File::Temp was missing as a dependency.
• Known Issues
  • Cygwin support is still broken.
  • PAR does not include utf8_heavy.pl nor unicore/* for scripts that has "use utf8;". This has since been fixed by Module::ScanDeps 0.18.

[Changes for 0.65 - March 9, 2003]

This release comes with several significant improvements:

• Automatic binary installation

Previously, users without a C compiler cannot build the 'parl' executable, and is therefore unable to create self-contained binaries using 'pp'.

Now, if there is a binary package available for that architecture under my CPAN directory, the Makefile.PL script will automatically fetch it, unpack into blib/, and the installation will continue as normal, resulting in a fully-functional 'pp'.

This feature is part of the soon-to-be-released Module::Install framework; it will greatly benefit all CPAN authors with non-pure-perl distributions.

• POD stripping

Packages generated with 'pp' will now strip POD sections from all packed dependencies (your own scripts is unaffected); all binary executables will save at least 276732 bytes, with additional ~20% saving in additional packed dependencies.

You can turn off this feature with the PAR_VERBATIM environment variable.

• XS Incompatibility solved

Because 'pp'-generated executables includes some fixed version of shared libraries (IO, Zlib, etc), they used to break when the target system has different version of shared libraries.

Now PAR::Heavy intercepts DynaLoader::dl_expandspec to always prefer the library inside the PAR file, so this issue is resolved.

• 5.6.1 Reclaimed

Thanks to Sisyphus and various others, building on Perl 5.6.1 (with its old ExtUtils::MakeMaker and lack of PTHREAD_ATFORK) now works again.

[Changes for 0.64 - March 2, 2003]

• New Features
  • The t/0-signature.t test is re-enabled for people using my Module::Signature to verify the module's OpenPGP signature.
  • This release is the first distribution on CPAN to use the Module::Install framework, which is a stand-alone, extensible drop-in replacement for ExtUtils::MakeMaker that needs no extra action/prerequisites for end users.
• Bug Fixes
  • Dynamic loading on Win32 was broken, due to a binmode() bug reported by Bill Atkins, D. Menzel and others.
  • Building on Win32 in directory names that contain spaces did not work.

[Changes for 0.63 - February 6, 2003]

• Bug Fixes
  • The 'parl' binary (which replaces the old 'par' or 'par.exe') didn't work properly when bundling perl modules for selfcontained executables, rendering 'pp' useless on machines without core perl.
