Revision history for Perl extension CGI::Header.

0.63 (1.00-RC16) Aug 1st, 2013

  - Merge CGI::Header::Extended into CGI::Header

0.62 (1.00-RC15) Jul 31st, 2013

  - Add CGI::Header::Extended to examples/

0.61 (1.00-RC14) Jun 16th, 2013

  - Add the following modules to examples/:
      * Blosxom::Header
      * CGI::Application::Header
      * CGI::Redirect
      * CGI::Redirect::Adapter
      * MyApp::Header

0.60 (1.00-RC13) Jun 16th, 2013

  - Add examples/
  - mv lib/CGI/Header/ examples/lib/CGI/Header/
  - CGI::Header::Apache2 isn't provided by this distribution.

0.59 (1.00-RC12) Jun 11th, 2013

  - Remove CGI::Header#redirect and location

0.58 (1.00-RC11) Jun 5th, 2013

  - CGI::Header::Apache2 updates request_rec->status_line properly

0.57 (1.00-RC10) Jun 1st, 2013

  - CGI::Header::Standalone is separated into CGI::Header::Adapter
    and Apache2. Apache1 is not available at this time.

0.56 (1.00-RC9) May 31st, 2013

  - finalize() prints to STDOUT using CGI#print


    CGI::Header::Standalone will be separated into CGI::Header::Apache1
    and Apache2. For example, CGI::Header::Apache2 inherits from
    CGI::Header::Adapter which is a base class for adapters.

0.55 (1.00-RC8) May 22nd, 2013

  - Add CGI::Header::Standalone again as the alternative to CGI::Header

0.54 (1.00-RC7) May 20th, 2013

  - Rename CGI::Header#as_string to "finalize" since's header()
    method returns an empty string in "mod_perl" environment
  - Remove CGI::Header::Standalone

0.53 (1.00-RC6) May 19th, 2013


    - update EXAMPLES

0.52 (1.00-RC5) May 14th, 2013

  - Add tests for CGI::Header#clone. POD explains how CGI::Header copies
    its instances.
  - CGI::Header::Standalone#as_string removes CRLF from Status-Line properly.
  - Tests require Test::MockTime (Thanks to CPAN Testers)

0.51 (1.00-RC4) May 13th, 2013

  - Add CGI::Header::Standalone that doesn't depend on's
    header() method
  - Add clone() method to CGI::Header

0.50 (1.00-RC3) Apr 23rd, 2013

  - Tests don't depend on Test::Exception (Thanks to CPAN testers)

0.49 (RC-1.00) Apr 22nd, 2013

  - Remove rehash(). new() normalizes property names automatically.

0.48 (RC-1.00) Apr 20th, 2013

  - Add tests for EXAMPLES
  - Tests require CGI::Simple
  - Release candidate for CGI::Header 1.00 (RC-1.00)

0.47  Apr 12th, 2013

  - Remove handler() and add redirect() instead
  - Rename cookie() to cookies() since the "cookie" property can be an
  - Remove push_cookie(). It's up to you to decide how to manage HTTP cookies.
    For example, Plack::Response#cookies behaves like HASH. On the other
    hand, Mojo::Message::Response#cookies behaves like ARRAY.

0.46  Apr 11th, 2013

  - Remove CGI::Header::PSGI from this distribution. Sorry for confusing
  - Simplify cookie() and p3p()
  - push_cookie() creates CGI::Cookie object automatically

0.45  Apr 10th, 2013

  - Add CGI::Header::PSGI to this distribution and rewrite the module


    - Rewrite test suite entirely
    - Remove flatten() and as_hashref() from CGI::Header

0.44  Apr 9th, 2013


    - Revise new() entirely

0.43  Apr 8th, 2013


    - Remove dispatch tables used by set() and delete()
    - Remove tie() interface

0.42  Apr 8th, 2013

  - Add handler() attribute which defaults to 'header'.
    If handler() is set to 'redirect', as_string() will invoke:

        $h->query->redirect( $h->header )


    - Remove CGI::Header::Redirect and t/31_cgi_redirect.t
    - Remove t/32_nph_pragma.t
    - Remove push_p3p()

0.41  Apr 8th, 2013

  - CGI::Header::Redirect is obsolete and will be removed in 0.42


  - Simplify get() and exists(). Namely,



      exists $h->as_hashref->{'Content-Type'};

  - Remove the following methods:
      * is_empty
      * field_names
      * is_empty
      * SCALAR
      * p3p_tags

  - Normalized property names doesn't start with a dash,
    and also use dashes instead of underscores:

      "-Content_Length" -> "content-length"


    Dispatch tables used by get(), set(), exists() and delete() will be
    removed gradually, and so ver. 0.4x will be quite unstable.
    Sorry for your inconvenience.

0.40  Apr 7th, 2013

  - field_names() is obsolete and will be removed in 0.41
  - Add as_hashref(). get() and exists() will be replaced with this method:
      $h->get('Content-Type'); # <=> $h->as_hashref->{'Content-Type'}
      $h->exists('Content-Type'); # <=> exists $h->as_hashref->{'Content-Type'}

  - p3p_tags() is obsolete and will be renamed to p3p() in 0.41
  - each() is obsolete and will be removed in 0.41
  - is_empty() is obsolete and will be removed in 0.41
  - Add the following methods:
        * charset
        * cookie
        * location
        * push_cookie
        * push_p3p
        * status
        * target
        * type


    - Doesn't overload '""' and 'bool' anymore
    - flatten() doesn't accept any argument

0.35  Mar 22nd, 2013

  - lc() is obsolete and will be removed in 0.36
  - get(), set(), exists() or delete() throws an exception
    in the following situation:

      $header->set( 'Type' => 'text/plain' );
      # die "'-type' can't be used as a field name"

  - SCALAR returns true if the -nph pragma is enabled
  - Since the following class methods are unstable,
    they are not documented:

      * normalize_field_name
      * normalize_property_name
      * get_property_names
      * is_reserved_name
      * get_alias

0.34  Mar 16th, 2013

  - Add support for -nph pragma:

      use CGI qw(-nph);
      my $h = CGI::Header->new;
      $h->nph; # => true

    If -nph pragma is enabled, you can't set nph() to FALSE:

      $h->nph(0); # die "Modification of a read-only value attempted"

    You can check whether the pragma is enabled or not as follows:

      $h->query->nph; # <=> $CGI::NPH

    You can also set $CGI::NPH to FALSE:

      $h->nph(0); # lives_ok

0.33  Mar 15th, 2013

  - Add tests for CGI::Header::Redirect
  - Fix POD: "CGI::Header::Redirect#is_empty always returns false"
  - Update dispatch tables to maintain this module more easily
  - Add the following class methods:
      * time2str
      * normalize

0.32  Mar 9th, 2013

  - Add CGI::Header::Redirect, an adapter for the CGI::redirect() function.
    CGI::Header::Redirect inherits from CGI::Header, and also overrides
    some methods.

0.31  Mar 8th, 2013

  - add get_alias() which returns the alias of the given property name:

      my $alias = CGI::Header->get_alias('content_type'); # => 'type'

0.30  Mar 4th, 2013

  - The following operators are overloaded:

      ""   -> as_string
      bool -> SCALAR

  - env() is obsolete and will be removed in 0.31.




    Summary: env() was replaced with query()

    - Add query() method which returns your query object.
      You can't pass your current environment (\%ENV) to new() anymore.

        my $header = { -type => 'text/plain' };
        my $h = CGI::Header->new( $header, \%ENV );


        use CGI;
        my $query = CGI->new;
        my $h = CGI::Header->new( $header, $query );

      query() defaults to $CGI::Q. Functions exported by
      depends on this query object. In other words, when you choose
      the procedural interface of, the module behaves like
      a Singleton class.

        # $query can be omitted when you choose the procedural
        # interface of
        my $h = CGI::Header->new( $header );

    - as_string() become a shortcut for:

        $h->query->header( $h->header )

      and so you can't pass $eol to as_string() anymore.


     CGI::Header is not compatible with CGI::Simple at this time.
     This module will be adapted to CGI::Simple gradually.
     (no_cache() isn't supported by, for example)

0.22  Feb 26th, 2013

  This distribution doesn't contain CGI::Header::PSGI anymore,
  which was separated into another distribution, CGI-Header-PSGI.

  The following files were removed:

    - lib/CGI/Header/
    - t/31_psgi_header.t
    - t/40_psgi_header.t
    - t/41_psgi_redirect.t

  This distribution doesn't require the following modules anymore:

    - Exporter
    - CGI::PSGI (for testing)

  There are no code changes besides incrementing the version number
  since CGI-Header-0.21.

0.21  Feb 25th, 2013


    - psgi_header() is compatible with CGI::Simple's header() method.
      Namely, psgi_header() can be configured by no_cache() method.
      If no_cache() isn't available, that method will be ignored simply.
      And so psgi_header() is compatible with as well.

    - I'm not sure about whether to use Role::Tiny ;)

    - [BUG FIX] psgi_redirect() invokes self_url(), not url()

    - Imports CGI::PSGI's psgi_headers.t and redirect.t

0.20  Feb 24th, 2013


0.19  Feb 11th, 2013

  Add CGI::Header::PSGI which exports two methods on demand: psgi_header()
  and psgi_redirect().

    use parent 'CGI';
    use CGI::Header::PSGI qw(psgi_header psgi_redirect);

  CGI::Header::PSGI helps you create your own CGI::PSGI-compatible class.


    - rehash() and new() rename '-uri' and '-url' to '-location'

    - flatten() and each() stringify CGI::Cookie objects by default.

0.18  Feb 9th, 2013

  - You can pass a media type to new() in the following situation:

      my $h = CGI::Header->new('text/plain');
      $h->header; # => { -type => 'text/plain' }

  - new() throws an exception in the following situation:

      my $h = CGI::Header->new( -foo => 'bar', '-baz' );
      # die "Odd number of elements in hash assignment"


    The following methods are unstable:

      - $h->set( 'Content-Type => $value )
      - $h->set( 'P3P' => $value )
      - $h->set( 'Expires' => $value )

        I'm not sure about how to process these headers properly at this time.

0.17  Jan 18th, 2013




    - Fix META.yml ("version" was broken)

0.16  Jan 14th, 2013


    - rehash() throws an exception when a property name is duplicated:

        my $header = {
            -Type        => 'text/plain',
            Content_Type => 'text/html',

        my $h = CGI::Header->new( $header );
        $h->rehash; # die "Property '-type' already exists"

      If it was allowed to overwrite existent properties,
      it would be essentially impossible to predict 
      the overwritten value of '-type' in the above example:

        $h->header->{-type}; # => 'text/html' or 'text/plain' ?

    - In addition to HTTP header properties,
      new() accepts '-env' property which represents your current environment:

        my $h = CGI::Header->new(
            -type => 'text/plain',
            -env  => \%ENV,

        $h->header; # => { -type => 'text/plain' }
        $h->env;    # => \%ENV

      Unlike the above case, if a property name is duplicated,
      that property will be overwritten silently:

        my $h = CGI::Header->new(
            -Type        => 'text/plain',
            Content_Type => 'text/html',

        $h->header->{-type}; # => "text/html"


    Add a subtest called 'as_string()' to t/10_basic.t

0.15  Jan 11th, 2013

  Add env() which defaults to \%ENV. new() receives an additional
  argument which determines the value of the attribute.
     my $header = CGI::Header->new({ -type => 'text/plain' }, \%ENV);
     $header->env; # => \%ENV


    - Add psgi_headers.t which requires CGI::PSGI
    - new() returns an object based on a blessed hash.

0.14  Jan 9th, 2013

  - set() and delete() throw exceptions when the specified header field
    is read-only.
  - get() returns undef in the following situations:

      $header->header; # => { -expires => q{}, ... }
      $header->get( 'Expires' ); # => undef

      $header->header; # => { -p3p => q{}, ... }
      $header->get( 'P3P' ); # => undef


    id() is aliased to Scalar::Util::refaddr()

0.13  Jan 8th, 2013

  - clear() and each() return the current object itself
  - set() returns the given value:
      $header->set( 'Foo' => 'bar' ); # => "bar"


    Correct the following warning message:
      "Can't set '-content_type' to neither undef nor an empty string"
    This message was replaced with:
      "Can set '-content_type' to neither undef nor an empty string"


    Add "Server" and "Date" to "LIMITATIONS" 

0.12  Jan 7th, 2013

    - Rename _normalize() to _lc()
    - Add a benchmark against HTTP::Response->parse

    - Add HTTP::Headers to "SEE ALSO"

0.11  Dec 16th, 2012
  - Add FIRSTKEY() and NEXTKEY(). These methods were implemented to
    test this module itself.
  - flatten() receives optional $is_recursive argument
    which determines whether to flatten the Set-Cookie headers recursively.
    $is_recursive defaults to true.
  - flatten() and each() don't stringify CGI::Cookie objects.
  - field_names() returns a list of field names in a random order

0.10  Dec 14th, 2012
  - p3p_tags() returns the number of P3P tags
    instead of the first element in scalar context
  - rehash() returns the current object itself:
      my @headers = CGI::Header->new(@args)->rehash->flatten;
  - each() doesn't depend on field_names().
    field_names() depends on each().
    As a result, if Set-Cookie header is multi-valued,
    field_names() will return a list which contains duplicate values.
    I don't know how to solve this problem at this time.

0.09  Nov 13th, 2012
  - has charset() attribute which defaults to 'ISO-8859-1'.
    CGI::header() function depends on this attribute.
    I noticed this module depends on the default value, 'ISO-8859-1',
    and so decided to remove this dependency because this module
    shouldn't depend on the internal state of
        my $h = CGI::Header->new( -type => 'text/plain' );
        $h->get( 'Content-Type' ); # => "text/plain; charset=ISO-8859-1"
        $h->get( 'Content-Type' ); # => "text/plain"

0.08  Nov 13th, 2012
  - reimplemented rehash()
  - [DOCUMENTATION] describe how this module normalizes parameter names

0.07  Nov 12th, 2012

0.06  Nov 11th, 2012
  - First release

0.05  Nov 10th, 2012
  - add rehash() method which rebuilds header hash references

0.04  Nov 7th, 2012
  - reorganized tests using subtest() function exported by Test::More
  - doesn't overload '""' (stringify) with as_string()
    because this module isn't the replacement of CGI::header() function.
    I think CGI::header() should be used to stringify
    header hash references in most cases.
  - each() doesn't stringify values (cf. HTTP::Headers->scan),
    and so the callback function will receive raw CGI::Cookie objects.
  - On the other hand, flatten() forces stringification.
    flatten() may be called to generate PSGI-compatible header array

0.03  Oct 7th, 2012
  - add a benchmark against HTTP::Parser::XS
  - update POD
  - add t/server.t
  - tests require 3.51 because the distribution contains t/headers.t

0.02  Oct 4th, 2012
  - tests require 3.60 and HTTP::Date
  - fix typo

0.01  Sep 23rd, 2012
  - Forked from Blosxom::Header
