1.00 2011-06-11

• Fix documentation indexing on search.cpan.org. Reported by Lutz Gehlen. RT #68756.

0.99 2011-05-27

• The metadata file - META.{json,yml} - had references to a different distro because of a copy and paste error. Reported by Bernhad Graf. RT #68514.

0.98 2011-04-23

• Attribute::Params::Validate's $VERSION regressed in 0.96. It now manually set to 1.07. Reported by tokuhirom. RT #67715.

0.97 2011-04-19

• The spec validation added in 0.96 broke MooseX::Params::Validate, so it has been removed until I can work out how to make the two modules play nice.

0.96 2011-04-19

• The XS version of the code always called Carp::confess, regardless of whether you provided your own on_fail callback. Reported by Scott Bolte. RT #66359.
• There were a couple spots that called eval without localizing $@ first. RT #58087.
• The parameters for each key validation (can, isa, regex) are now checked, and an error is thrown if any of the keys are not valid. Basically, we validate the validation spec. Based on a patch by Andreas Faafeng. RT #57831.
• Lots of little pod fixes. RT #61002.
• This module now requires Perl 5.8.1.
• Switched to version 2.0 of the Artistic License.

0.95 2010-02-16

• Skip t/29-taint-mode.t entirely, since it seems to randomly fail for people, despite already being marked a todo test.

0.94 2009-12-01

• Removed the Makefile.PL entirely. If it was used then the XS code was never built, because I'm using the Module::Build XS layout. Reported by jawnsy on IRC.

0.93 2009-11-30

• If the pure Perl version of validate() received a hash reference it would alter that reference directly. Reported by Paul Eckhardt. RT #51155.
• Author-only tests now only run if $ENV{AUTHOR_TESTING} is true. RT #49890.

0.92 2009-09-25

• Switched to Module::Build and don't try to detect a compiler. If you want to force a Perl-only build, run the Build.PL as "perl Build.PL --pp". Addresses RT #44719 (more or less), Reported by Olivier Mengué.
• Require Scalar::Util 1.10, since that is the first version with looks_like_number. Reported by Olivier Mengué. RT #45103.
• Require Attribute::Handlers 0.79. Reported by Olivier Mengué. RT #44066.

0.91 2008-05-03

• The fix for handling @_'s readonly-ness introduced a refcounting bug. One symptom of this was a failing Log::Dispatch test. Reported by Andreas Koenig. RT #35608.

0.90 2008-05-01

• Make the XS version of Params::Validate recognize regexp objects with Perl 5.11.0-to-be. Patch by Andreas Koenig. RT #32872.
• With the XS version, when you passed @_ directly to validate() and then got a hash reference back, the values of that hash reference would be marked readonly. Reported by W J Moore. RT #34410.

0.89 2007-10-31

• With validation turned off, the pure Perl version incorrectly ignored an odd number of parameters when a hash was expected (no validation still does the bare minimum of checks needed to set defaults).
• Added pod & pod coverage tests.
• Modernized test suite to use Test::More and fixed some test suite bugs along the way.
• Attribute::Params::Validate would die when given a ValidatePos attribute containing one element.
• More tests are skipped on 5.6.0.

0.88 2007-03-07

• The XS version threw an error when it attempted to do "isa" or "can" validation on a value that was not a string or object, such as undef or a number. Reported by Steffen Winkler. RT #25229.
• Fixed a compilation failure with bleadperl (5.9.x) that happened because of a new scalar type introduced in blead. Patch by Nicholas Clark. Fixes RT #24458.

0.87 2007-01-18

• When determining the caller of a function in the XS version, use Perl's caller() function rather than CopSTASHPV. The caller() function apparently ignores the DB package, whereas the latter doesn't. This caused validate_options to be ignored when running under profiling (and probably the debugger as well). Thanks to Jeff Weisberg for pointing this out.

0.86 2006-08-09

• I cannot get this module to compile with Perl 5.00504 any more. I get errors from including CORE/perl.h, so the problem may be outside my control, but help is welcome.
  • Only turn inlining on if __GNUC__ is defined, since it seems that so many other compilers don't support this. RT #20881.
  • Removed spaces in #define, #ifdef, etc. Suggested by Peter Marquardt.
  • If a type is specified as a string ('SCALAR', not SCALAR), this is now caught and a useful error is thrown. RT #9660.

0.85 2006-06-07

• Compiles without warnings under gcc's -Wall. Warnings reported by Scott Godin.
• Turned off inlining with HP-UX compiler. RT #19763.

0.84 2006-05-29

• The XS version of the code used Carp::croak to report failures, while the Perl version used Carp::confess. The module has always been documented as using confess, so now the XS version uses this.
• The new compiler detection code always returned false if you didn't have ExtUtils::CBuilder installed.

0.83 2006-05-28

• Change how C compiler detection is done in the Makefile.PL so it does not rely on having make on the system. The new way should work on (most?) Unix and Win32 systems. Suggested by David Golden. See RT 18969 (for DateTime.pm, but equally applicable to this module). Will hopefully fix RT 17644.
• Previously, if a parameter was undefined, regex checks for that parameter always failed. However, it's quite possible for a regex to successfully match an undefined value (qr/^$/, for example). Now the code treats undef as an empty string ('') in regex checks. Reported by Duncan Salada.

0.82 2006-05-09

• Disabled function inlining if MSCVER is defined. Patch from Audrey Tang.
• Check isa by calling it as a method on the thing being checked.
• Do the same for can in the pure Perl version. This was already fixed for the XS version in 0.75.

0.81 2006-04-01

• Speed up no validation in XS version by short-circuiting immediately if validation is off. This gives a noticeable speed boost when $ENV{NO_VALIDATION} is in use. Patch by Daisuke Maki.
• Inlined some C functions for additional speed in the XS version. Patch by Daisuke Maki.

0.80 2006-01-22

• If a undef value was given for a parameter that had a regex in its spec, a warning was emitted. RT #15196.

0.79 2006-01-13

• The XS version of Params::Validate did not work if a spec hash reference was marked Readonly using Readonly::XS.
• Added some tests for using tied values for params or spec, and discovered that a tied spec causes a segfault, but could not figure out how to fix this (Grr, Perl magic is a huge pain in the nether regions).

0.78 2005-07-19

• If an overloaded object returned false in boolean context, then it would always fail "can" tests. Patch by Chi-Fung Fan.

0.77 2005-04-29

• Neither --xs or --pm worked with the Makefile.PL the way they were supposed to. Reported by Doug Treder.
• Moved source to my personal SVN repo. https://svn.urth.org/svn/Params-Validate
• Updated ppport.h, which allows XS version to work with 5.00504. This was broken since 0.75, at least.

0.76 2004-11-13

(The "Cancan some more" release)

• Make sure that both the XS and Perl versions give the same error when checking "can" for an undefined value.

0.75 2004-11-13

(The "Cancan" release)

• When checking if a parameter has a method, P::V now calls the ->can method on the parameter, rather than calling UNIVERSAL::can() directly. Requested by Don Armstrong.

0.74 2004-04-04

(The "I hate old Perls" release)

• Sometimes, but not always, Perl 5.00504 and 5.00503 cannot produce a string value for a glob (as opposed to glob reference) parameter. This was uncovered by a test in the HTML::Mason test suite, but I cannot reproduce it in a simple testable form for this test suite. Sigh ...

0.73 2004-03-28

(The "YAPC::Taipei release party" release)

• The minimum number of arguments required was reported incorrectly by the XS code when a call to validate_pos() failed because too few parameters were given. Patch from Britton Kerin.
• Add a new untaint key to the validation spec, which untaints a value if it passes its validation checks.

0.72 2003-12-03

• If a normalize_keys callback returns the same normalized key for two different inputs, Params::Validate will die.
• The pure Perl implementation had a bug where if the same hash reference was used for the spec in multiple calls to validate(), then any call made after a parameter failed a validation check could exhibit strange behaviors (like parameters passing that shouldn't, etc.). This was due to the fact that the Perl implementation uses each() internally, and was leaving the hash's iterator partially iterated. Reported via an apparent problem with DateTime.pm by Jost Krieger.

0.71 2003-12-02

• Suppressed some annoying "subroutine redefined" warnings if the pure Perl version ended up being loaded after attempting to load the XS version.

0.70 2003-11-23

• Any validation call that used a callback leaked memory when using the XS version. This was introduced in 0.67, when callbacks started receiving a reference to the parameters as a second argument. Reported by Eugene van der Pijll.

0.69 2003-11-03

• The key normalization feature introduced in 0.66 leaked one SV* every time a parameter hash was run through the XS version of validate() or validate_with(). This happened if one of normalize_keys, allow_extra, or ignore_case was set, or if validate_with() was used. Upgrading is strongly recommended! Reported by Ruslan.

0.68 2003-10-21

• Added spiffy new parameter dependency feature. Implemented by Daisuke Maki.

0.67 2003-10-10

• The test count for 06-option.t was off. Reported by Christian Schaffner.
• Validation callbacks now receive a reference to the (normalized) parameter hash/array as their second argument.
• Shut up an "unitialized value in subroutine entry" warning caused by calling validate_pos() with an undef value in the parameter array. This was introduced in 0.66.

0.66 2003-10-08

• Skip a few more tests under Perl 5.6.0. Patch from Christian Schaffner.
• Error messages now include the stringified value of the variable that was invalid. Implemented by Daisuke Maki.
• Added a new parameter normalization callback feature, the "normalize_keys" option. Implemented by Daisuke Maki.
  • The "strip_leading" and "ignore_case" options are now deprecated. Use the new "normalize" feature instead.

0.65 2003-08-07

• It is now possible to turn validation on and off at runtime. To make this easier, it can be set via the PERL_NO_VALIDATION environment variable, or the $Params::Validate::NO_VALIDATION global variable. Go ahead, shoot yourself in the foot with it!

0.64 2003-07-14

• Fix an XS compilation error under 5.6.1:

Validate.xs:In function `validate_isa': Validate.xs:381: `perl_on_error' undeclared (first use in this function)

0.63 2003-07-14

• The XS version of validate_with failed if the params key contained an array reference containing a single hash reference. Since this works with the pure Perl version, it should work with the XS version. Reported by Diab Jerius. Bug #2791 on rt.cpan.org.

0.62 2003-06-25

• Remove a warn() statement left in from debugging. Reported by Shane McCarron.

0.61 2003-06-23

• The last release had some debugging code left in which tried to load Devel::StackTrace. Reported by Iain Truskett.

0.60 2003-06-21

• Fixed a weird segfault that could occur with Perl 5.6.1 when a user-defined on_fail callback died with an object as its argument. This only happened with the XS version of the code. Reported by Ken Williams.

  The end result is that the version of the XS code that is used with Perl 5.6.0 and 5.6.1 is slightly slower than that used with 5.00503 or 5.8.0, as it requires an additional Perl-level wrapper.

• Use XSLoader in preference to Dynaloader with Perl 5.6.0+.

0.59 2003-05-24

• If an odd number of parameters was given to validate() in the array as its first argument, the error given would be different depending on whether or not the pure Perl or XS version of the code was being used.
• Fixed incredibly odd bug that occurred in XS code when tainting was on with Perl 5.00503. Unfortunately, the only test case that reliably reproduces this is one of Mason's tests, so no test was added.

0.58 2003-04-03

• Fix some compiler warnings from MS Visual Studio 6. Reported by Ron Hill.

0.57 2003-02-28

• When called from the main body of a script, the validation routines would cause an undefined value warning if validation failed. Reported by Britton Kerin and fixed by Ilya Martynov.

0.56 2003-02-24

• The XS code that handled callbacks expected all callbacks to return an integer, instead of simply testing the returned value for truth. This could cause strange warnings like 'Argument "InMemory" isn't numeric in subroutine entry...'. Based on a bug report from Robert Dick for another module I wrote (Lingua::ZH::CCDICT).

0.55 2003-02-21

• Fixed Params::Validate for Perl configurations where sizeof(IV) != sizeof(int). Reported by Alain Barbet.

0.54 2003-02-20

• Something around test 5 in 06-options.t appear to cause Perl to die/segfault/something under 5.6.0. These tests will be skipped with 5.6.0 in the future. Reported by Christian Schaffner.

0.53 2003-02-19

• When testing for a compiler, use nmake on Win32. Implemented by Ronald Hill.

0.52 2003-02-14

• Added regex validation option.

0.51 2003-01-14

• Added copyright info to each source file. Added LICENSE file to distro.

0.50 2003-01-09

• Added an XS implementation, written by Ilya Martynov. The pure Perl implementation is still included as a fallback for users who do not have a compiler handy. The XS implementation gives a speed boost of 150% to 300%, depending on the complexity of the validation being done.

  This XS code is known to work Perl 5.00503+, but it may not work with earlier versions of Perl.

0.24 2002-07-19

• Fix Attribute::Params::Validate docs to show that attribute declaration must have open paren immediately after "Validate" or "ValidatePos". Reported by Britton Kerin.
• Fix bug with Perl 5.8.0 when in PERL_NO_VALIDATION mode and calling validate() expecting a hash ref to be returned. Reported by Randal Schwartz.

0.23 2002-07-19

• Argh. In 0.22 some of the tests printed their test counts (1..x) after doing the tests. This works with newer versions of Test::Harness so I didn't notice it. Reported by Peter Asemann.

0.22 2002-07-15

• The last version's tarball was a mess, and had blib and other junk in it. This is a nice clean one.

0.21 2002-07-14

• The various validation functions are now context sensitive, and will return a reference in scalar context. This may be a helpful speedup, especially for large parameter lists.

0.20 2002-07-13

• Improved the speed of both validate() and validate_pos() by about 20-25%.
• Improved the speed of the 'no validation' mode for validate() by over 30%, for validation_pos() by 15%, and for validate_with() by 125%.
• The speed of validate_with() has been improved by over 100%, but this was at the expense of not validating its own incoming arguments, thus making it a little more fragile.
• The PERL_NO_VALIDATION env var is now only checked when the module is loaded. This means you cannot change it mid-program. This is a backwards incompatibility.

0.18 2002-06-18

• Added a new function, validate_with(), that allow you to set various options on a per-invocation basis, rather than on a per-package basis. Patch by Ken Williams.

0.17 2002-06-15

• Fix a doc nit where I had a wrong code example. Reported by Britton Kerin.
• Added a new validation option parameter, stack_skip, which allows you to change how errors are reported by Params::Validate.

0.16 2002-05-11

• Improve skipping of tests when run with 5.6.0. Patch by Ken Williams.
• Silence an uninit value warning

0.15 2002-04-19

• validate_pos would die stupidly when it received an array with an odd number of elements.

0.14 2002-03-14

• validate_pos used exists on an array element, which only works with Perl 5.6.0. This release makes it work 5.00503 again. Reported by Jon Swartz.

0.13 2002-03-10

• Apply some of the same optimizations to positional parameters. The speedup here seems to be about 7-8%.
• Fix stupid bug in 04-defaults tests.

0.12 2002-03-10

• Add BOOLEAN type (equivalent to UNDEF | SCALAR). Suggested by Ken Williams.
• This version is about 8-10% faster on named parameters than previous versions. This may not seem like that much but if most, or all, of your subroutines/methods use validation then this can be a significant improvement.
• This version has slightly different semantics for dealing with missing parameters. Previously, if parameters were missing, an exception was thrown before any of the other validation parameters were checked. Now, the validation parameters (type, isa, etc.) are checked first, so that these errors will show up before missing parameters.

0.11 2002-01-04

• Accidentally removed the set_options function (in 0.08). Though this will go away in the future it isn't happening quite yet.

0.10 2002-01-04

• Apparently making a tarball for CPAN is beyond my limited abilities. 0.09 was missing a file needed for tests. Also reported by Blair Zajac.
• When running Makefile.PL you get some warnings that can be ignored. Add a message saying you can ignore them.

0.09 2002-01-04

• I forgot to put the Makefile.PL in the MANIFEST. I am dumb. Reported by Blair Zajac.

0.08 2002-01-03

• Explicitly mention that, by default, Params::Validate uses Carp::confess to report a validation failure. Suggested by Mark Stosberg.
• The 'NO_VALIDATION' mode was seriously broken in that it didn't handle defaults at all.
• The 'NO_VALIDATION' env var was mis-documented as being 'NO_VALIDATE'.
• The 'NO_VALIDATION' env var is now 'PERL_NO_VALIDATION' and this method of disabling validation is no longer considered alpha.
• The validation functions now check this environment variable every time they are called. This is probably a bit slower than the previous implementation, which only checked once when the module was loaded. If you have a problem with this, let me know.

0.07 2001-09-23

• Fix problem with CPAN shell's 'r' command that Attribute::Params::Validate was causing with older Perl's. Reported by Rob BloodGood.
• Add ability to specify defaults for parameters and get a new hash/array back from validate or validate_pos. Partial patch submitted by Ken Williams.

0.06 2001-08-23

• Require Attribute::Handlers if using Perl 5.6.0+.
• fix doc nits.

0.05 2001-08-23

• Added Attribute::Params::Validate - do validation via attributes!
• Rename set_options to validation_options. This can now be exported safely and is included in the :all export tag. set_options is deprecated and will be removed in a future release. Thanks to Jon Swartz for the suggestion.

0.04 2001-04-14

• Tweaks to make the code work under 5.00404

0.03 2001-03-17

• Make sure all error messages contain the name of the subroutine that was called.
• The error message given when an argument doesn't match the 'isa' spec has been improved.
• Use Carp::confess by default when dying with an error. This produces a more useful error message.

0.02 2001-03-06

• Fix a bug in the test suite that caused failures in 5.6.0.

0.01 2001-02-16

• Original release
