Changes   [plain text]

0.80 Jan 22, 2006

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

0.79 Jan 13, 2006

- 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

0.78 Jul 19, 2005

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

0.77 Apr 29, 2005

- 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.

- Updated ppport.h, which allows XS version to work with 5.00504.
This was broken since 0.75, at least.

0.76 Nov 13, 2004 (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 Nov 13, 2004 (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 Apr 4, 2004 (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 Mar 28, 2004  (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 Dec 3, 2003

- 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 by Jost

0.71 Dec 2, 2003

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

0.70 Nov 23, 2003

- 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 Nov 3, 2003

- 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 Oct 21, 2003

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

0.67 Oct 10, 2003

- The test count for 06-option.t was off.  Reported by Christian

- 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 Oct 08, 2003

- Skip a few more tests under Perl 5.6.0.  Patch from Christian

- 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 Aug 07, 2003

- 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 Jul 14, 2003

- 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 Jul 14, 2003

- 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

0.62 Jun 25, 2003

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

0.61 Jun 23, 2003

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

0.60 Jun 21, 2003

- 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

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 May 24, 2003

- 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 Apr 03, 2003

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

0.57 Feb 28, 2003

- 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 Feb 24, 2003

- The XS code that handled callbacks expects 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 Feb 21, 2003

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

0.54 Feb 20, 2003

- 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 Feb 19, 2003

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

0.52 Feb 14, 2003

- Added regex validation option.

0.51 Jan 14, 2003

- Added copyright info to each source file.  Added LICENSE file to

0.50 Jan 9, 2003

- 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

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

0.24  Jul 19, 2002

- 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

0.23 Jul 19, 2002

- 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 Jul 15, 2002

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

0.21 Jul 14, 2002

- 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 Jul 13, 2002

- More optimization work.

-- Improved the speed of both validate() and validate_pos() by about

-- Improved the speed of the 'no validation' mode for validate() by
over 30%, for validation_pos() by 15%, and for validate_with() by

-- 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 June 18, 2002

- 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 Jun 15, 2002

- Fix a doc nit where I had a wrong code example.  Reported by Britton

- Added a new validation option parameter, stack_skip, which allows
you to change how errors are reported by Params::Validate.

0.16 May 11, 2002

- Improve skipping of tests when run with 5.6.0.  Patch by Ken

- Silence an uninit value warning

0.15 Apr 19, 2002

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

0.14 Mar 14, 2002

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

0.13 Mar 10, 2002

- 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 Mar 10, 2002

- Add BOOLEAN type (equivalent to UNDEF | SCALAR).  Suggested by Ken

- 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

- 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

0.11 Jan 04, 2002

- 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 Jan 04, 2002

- Apparently making a tarball for CPAN is beyond my limited abilities.
0.09 was missing a file needed for tests.  Also reported by Blair

- When running Makefile.PL you get some warnings that can be ignored.
Add a message saying you can ignore them.

0.09 Jan 04, 2002

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

0.08 Jan 03, 2002

- Explicitly mention that, by default, Params::Validate uses
Carp::confess to report a validation failure.  Suggested by Mark

- 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

- 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 Sep 23, 2001

- 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 Aug 23, 2001

- Require Attribute::Handlers if using Perl 5.6.0+.

- fix doc nits.

0.05 Aug 23, 2001

- 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 Apr 14, 2001

- tweaks to make the code work under 5.00404

0.03 Mar 17, 2001

- 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 Mar 6, 2001

- fix a bug in the test suite that caused failures in 5.6.0.

0.01 Feb 16, 2001

- Original release
