2 1. Don't try to read data at all when POST > $POST_MAX.
3 2. Fixed bug that caused $cgi->param('name',undef,'value') to unset param('name') entirely.
4 3. Fixed bug in which upload() sometimes returns empty. (CPAN bug #12694).
5 4. Incorporated patch from BURAK@cpan.org to support HTTPcookies (CPAN bug 21019).
8 1. Patch from David Wheeler for CGI::Cookie->bake(). Uses mod_perl headers_out->add()
9 rather than headers_out->set().
10 2. Fixed problem identified by Andrei Voronkov in which start_form() output was screwed
11 up when initial argument begins with a dash and subsequent arguments do not.
12 3. Quashed uninitialized variable warnings coming from script_name(), url() and other
13 functions that require access to the PATH_INFO environment variable.
16 1. Added patch from Stephen Frost that allows one to suppress use of the temp file that is
17 created during uploads.
18 2. Fixed problem noted by Martin Foster in which regular expression meta-character terms
19 in the path information were not quoted, causing URL parsing
20 to fail on URLs that contained metacharacters (such as +).
21 3. More fixes to the url() method.
22 4. Removed "hack to fix broken PATH_INFO in MSII".
26 2. Patch from Steve Peters to default the document type to match the charset.
27 3. Fixed param() so that param(-name=>'foo',-values=>[]) sets the parameter to empty list.
29 Version 3.16 Wed Feb 8 13:29:11 EST 2006
30 1. header() -charset option now works even when the MIME type is not "text".
31 2. Fixed documentation for cookie() function and fastCGI.
32 3. Upload filehandles now only closed automatically on Windows systems.
33 4. Apache::Cookie compatibility fix from David Wheeler
34 5. CGI::Carp->fatalsToBrowser() does not work correctly with
35 mod_perl 2. No workaround is known.
36 6. Fixed text status code associated with 302 redirects. Should be "Found"
38 7. Fixed charset in start_html() and header() to be in synch.
40 Version 3.15 Wed Dec 7 15:13:22 EST 2005
41 1. Remove extraneous "?" from self_url() when URI contains a ? but no query string.
43 Version 3.14 Tue Dec 6 17:12:03 EST 2005
44 1. Fixed broken scrolling_list() select attribute.
47 1. Removed extraneous empty "?" from end of self_url().
50 1. Fixed virtual_port so that it works properly with https protocol.
51 2. Fixed documentation for upload_hook().
52 3. Added POSTDATA documentation.
53 4. Made upload_hook() work in function-oriented mode.
54 5. Fixed POST_MAX behavior so that it doesn't cause client to hang.
55 6. Disabled automatic tab indexes and added new -tabindex pragma to
56 turn automatic indexes back on.
57 7. The url() and self_url() methods now work better in the context of Apache
58 mod_rewrite. Be advised that path_info() may give you confusing results
59 when mod_rewrite is active because Apache calculates the path info *after*
60 rewriting. This is mostly worked around in url() and self_url(), but you
61 may notice some anomalies.
62 8. Removed empty (and non-validating) <div> from code emitted by end_form().
63 9. Fixed CGI::Carp to work correctly with Mod_perl 1.29 in an Apache 2 environment.
64 10. Setting $CGI::TMPDIRECTORY should now be effective.
67 1. Killed warning in CGI::Cookie about MOD_PERL_API_VERSION
68 2. Fixed append() so that it works in function mode.
69 3. Workaround for a bug that appears in Apache2 versions through 2.0.54
70 in which SCRIPT_NAME and PATH_INFO are incorrect if the additional path_info
71 contains a double slash. This workaround will handle the common case of
72 http://mysite.com/cgi-bin/log.cgi/http://www.some.other.site/args, but will
73 not handle the uncommon case of a ScriptAlias directive that adds additional
74 path information to the end of the translated URI.
77 1. Added Apache2::RequestIO, which is necessary for mp2 interoperability.
80 1. Fixed tabindex="0" when using CGI to create forms without a prior start_html
81 2. Removed warning about non-numeric MOD_PERL_API_VERSION.
84 1. update support for mod_perl 2.0. versions prior to
85 mod_perl 1.999_22 (2.0.0-RC5) are no longer supported.
88 1. Fixed typo in mod_perl detection.
92 1. Fixed bare call to script() in start_html

94 clobbering $@ when CGI functions are executed in an eval{}
96 3. mod_perl 2.0 version detection patch in CGI::Cookie provided by
98 4. autoEscape() flag is now respected when generating extra
100 5. Tests for *tag start/end generation from Shlomi Fish.
101 6. Support for can() method provided by Ron Savage.
102 7. Fix for lang='' when outputting XHTML.
103 8. Added support for chunked transfer encoding, as suggested by
105 9. Fixed clobbering of row and column headers in tableized radio
106 and checkbox groups, as reported by Nicolas Thierry-Mieg.
107 10. <Label> tags are now associated with form elements, as suggested
108 by accessibility guidelines.
109 11. The <?xml> directive produced by start_html is now turned off by
110 default and the charset is specified in a <meta> directive. Apparently
111 IE6 (and maybe some versions of Opera) were getting confused by this.
112 12. Support for tab indexes.
113 13. Retired the HTML docs. The POD docs are now primary documentation.
114 14. CGI::Carp now correctly detects and handles Apache::Dispatch.
115 15. CGI::Util::utf8_chr now correctly sets the UTF8 flag on 5.006 or
116 higher perls (fix courtesy Slaven Rezic).
121 1. Fixed uninitialized variable warning on start_form() when running
123 2. Fixed CGI::_set_attributes so that attributes with a - are handled
125 3. Fixed CGI::Carp::die() so as to avoid problems from _longmess()
127 4. If HTTP_X_FORWARDED_HOST is defined (i.e. running under a proxy),
128 the various functions that return HOST will use that instead.
129 5. Fix for undefined utf8() call in CGI::Util.
130 6. Changed the call to warningsToBrowser() in
131 CGI::Carp::fatalsToBrowser to call only after HTTP header is sent
132 (thanks to Didier Lebrun for noticing).
133 7. Patches from Dan Harkless to make CGI.pm validatable against HTML
135 8. Fixed an extraneous "foo=bar" appearing when extra style
136 parameters passed to start_html;
137 9. Fixed cross-site scripting bug in startform() pointed out by Dan
139 10. Fixed documentation to discuss list context behavior of
140 form-element generators explicitly.
141 11. Fixed incorrect results from end_form() when called in OO manner.
142 12. Fixed query string stripping in order to handle URLs containing
144 13. During server push, set NPH to 0 rather than 1. This is supposed
145 to fix problems with Apache.
146 14. Fixed incorrect processing of multipart form fields that contain
147 embedded quotes. There's still the issue of how to handle ones
148 that contain embedded semicolons, but no one has complained (yet).
149 15. Fixed documentation bug in -style argument to start_html()
150 16. Added -status argument to redirect().
154 1. Fixed the problem with mod_perl crashing when "defaults" button
159 1. Fix upload hook functionality

179 state saving still working.
180 7. Added code for underreads.
181 8. Fixed misleading description of redirect() and relative URLs in
183 9. Workaround for weird interaction of CGI::Carp with Safe module

654 CGI->image_button(), to fail.
655 4. Fixed bug which caused strong('CGI') to fail. Be careful to use
656 CGI::strong('CGI') and not CGI->strong('CGI'). The latter will
657 produce confusing results.

659 "filehandle as string" feature.
660 6. Added cgi_error() function.

685 start_ol(), end_ol(), and so forth now work (see the docs on how
686 to enable this feature).
687 6. Changed accept() to Accept(), sub() to Sub(). There's still a
688 conflict with reset(), but this will break too many existing

742 5. Table and other HTML3 functions are now part of the :standard set.
743 6. Small documentation fixes.

749 2. Split CGI.pm into CGI processing and HTML-generating modules.
750 3. More robust file upload (?still not working on the Macintosh?).
751 4. Bring in all the HTML4 functionality, particular the accessibility
756 1. file uploads failing because of VMS patch; fixed.
757 2. -dtd parameter was not being properly processed.
761 I finally got tired of all the 2.37 betas and released 2.38. The main
762 difference between this version and the last 2.37 beta (2.37b30) are
763 some fixes for VMS. This should allow file upload to work properly on
766 Version 2.37, various beta versions

778 7. Documented the import pragmas a little better.
779 8. Added a -compile switch to the use clause for the long-suffering
780 mod_perl and Perl compiler users.

784 11. Added documentation on escape(), unescape(), unescapeHTML() and
785 unescapeHTML() subroutines.
786 12. Added documentation on creating subclasses.
787 13. Fixed problem when calling $self->SUPER::foo() from inheriting

803 25. Removed autoloader warnings about absent MultipartBuffer::DESTROY.
804 26. Fixed non-sticky checkbox() when -name used without -value.
805 27. Hack to fix path_info() in IIS 2.0. Doesn't help with IIS 3.0.
806 28. Parameter syntax for debugging from command line now more
808 29. Added $DISABLE_UPLOAD to disable file uploads.
809 30. Added $POST_MAX to error out if POSTings exceed some ceiling.
810 31. Fixed url_param(), which wasn't working at all.
811 32. Fixed variable suicide problem in s///e expressions, where the
812 autoloader was needed during evaluation.
813 33. Removed excess spaces between elements of checkbox and radio
815 34. Can now create "valueless" submit buttons
816 35. Can now set path_info as well as read it.
817 36. ReadParse() now returns a useful function result.
818 37. import_names() now allows you to optionally clear out the
819 namespace before importing (for mod_perl users)
820 38. Made it possible to have a popup menu or radio button with a value
822 39. link() changed to Link() to avoid overriding native link function.
823 40. Takes advantage of mod_perl's register_cleanup() function to clear
825 41. <LAYER> and <ILAYER> added to :html3 functions.
826 42. Fixed problems with private tempfiles and NT/IIS systems.

828 44. Allow underscores to replace internal hyphens in parameter names.
829 45. CGI::Push supports heterogeneous MIME types and adjustable delays

834 48. Cookies now moved to their very own module.
835 49. Fixed documentation bug in CGI::Fast.
836 50. Added a :no_debug pragma to the import list.
840 1. Expanded JavaScript functionality
841 2. Preliminary support for cascading stylesheets
842 3. Security fixes for file uploads:
843 + Module will bail out if its temporary file already exists
844 + Temporary files can now be made completely private to avoid
845 peeking by other users or CGI scripts.
846 4. use CGI qw/:nph/ wasn't working correctly. Now it is.
847 5. Cookie and HTTP date formats didn't meet spec. Thanks to Mark
848 Fisher (fisherm@indy.tce.com) for catching and fixing this.
854 1. Robustified multipart file upload against incorrect syntax in
856 2. Fixed more problems with mod_perl.
857 3. Added -noScript parameter to start_html().
858 4. Documentation fixes.
866 1. Fixed a warning about an undefined environment variable.
867 2. Doug's patch for redirect() under mod_perl
868 3. Partial fix for busted inheritence from CGI::Apache
869 4. Documentation fixes.
873 1. Improved support for Apache's mod_perl.
874 2. Changes to better support inheritance.
879 1. New uploadInfo() method to obtain header information from uploaded
881 2. cookie() without any arguments returns all the cookies passed to a
883 3. Removed annoying warnings about $ENV{NPH} when running with the -w
885 4. Removed operator overloading throughout to make compatible with
886 new versions of perl.
887 5. -expires now implies the -date header, to avoid clock skew.
888 6. WebSite passes cookies in $ENV{COOKIE} rather than
889 $ENV{HTTP_COOKIE}. We now handle this, even though it's O'Reilly's
891 7. Tested successfully against new sfio I/O layer.
892 8. Documentation fixes.
896 1. Automatic detection of operating system at load time.
897 2. Changed select() function to Select() in order to avoid conflict
899 3. Added Tr() as an alternative to TR(); some people think it looks
901 4. Fixed problem with autoloading of MultipartBuffer::DESTROY code.
902 5. Added the following methods:
905 6. Automatic NPH mode when running under Microsoft IIS server.
910 2. Fixed problems that cropped up when useNamedParameters was set to
912 3. Prevent CGI::Carp::fatalsToBrowser() from crapping out when
913 encountering a die() within an eval().
914 4. Fixed problems with filehandle initializers.
918 1. Added support for NPH scripts; also fixes problems with Microsoft
920 2. Fixed a problem with checkbox() values not being correctly saved
922 3. Fixed a bug in which CGI objects created with empty string
923 initializers took on default values from earlier CGI objects.
924 4. Documentation fixes.
928 1. Small but important bug fix: the automatic capitalization of tag
929 attributes was accidentally capitalizing the VALUES as well as the
930 ATTRIBUTE names (oops).
934 1. Changed behavior of scrolling_list(), checkbox() and
935 checkbox_group() methods so that defaults are honored correctly.
936 The "fix" causes endform() to generate additional <INPUT
937 TYPE="HIDDEN"> tags -- don't be surpised.
938 2. Fixed bug involving the detection of the SSL protocol.
939 3. Fixed documentation error in position of the -meta argument in
941 4. HTML shortcuts now generate tags in ALL UPPERCASE.
942 5. start_html() now generates correct SGML header:
943 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
945 6. CGI::Carp no longer fails "use strict refs" pragma.
949 1. Fixed bug that caused bad redirection on destination URLs with
951 2. Fixed bug involving use_named_parameters() followed by
952 start_multipart_form()
953 3. Fixed bug that caused incorrect determination of binmode for
955 4. Spelling fixes on documentation.
959 1. Fixed bug that caused generation of lousy HTML for some form
961 2. Fixed uploading bug in Windows NT
962 3. Some code cleanup (not enough)
966 1. Fixed an obscure bug that caused scripts to fail mysteriously.
967 2. Fixed auto-caching bug.
968 3. Fixed bug that prevented HTML shortcuts from passing taint checks.
969 4. Fixed some -w warning problems.
973 1. New CGI::Fast module for use with FastCGI protocol. See pod
974 documentation for details.
975 2. Fixed problems with inheritance and autoloading.
976 3. Added TR() (<tr>) and PARAM() (<param>) methods to list of
977 exported HTML tag-generating functions.
978 4. Moved all CGI-related I/O to a bottleneck method so that this can
979 be overridden more easily in mod_perl (thanks to Doug MacEachern).
980 5. put() method as substitute for print() for use in mod_perl.
981 6. Fixed crash in tmpFileName() method.
982 7. Added tmpFileName(), startform() and endform() to export list.
983 8. Fixed problems with attributes in HTML shortcuts.
984 9. Functions that don't actually need access to the CGI object now no
985 longer generate a default one. May speed things up slightly.
986 10. Aesthetic improvements in generated HTML.
991 1. Added the -meta argument to start_html().
992 2. Fixed hidden fields (again).
993 3. Radio_group() and checkbox_group() now return an appropriate
994 scalar value when called in a scalar context, rather than
995 returning a numeric value!
996 4. Cleaned up the formatting of form elements to avoid unesthetic
997 extra spaces within the attributes.
998 5. HTML elements now correctly include the closing tag when
999 parameters are present but null: em('')
1000 6. Added password_field() to the export list.
1004 1. Dumped the SelfLoader because of problems with running with taint
1005 checks and rolled my own. Performance is now significantly
1007 2. Added HTML shortcuts.
1008 3. import() now adheres to the Perl module conventions, allowing
1009 CGI.pm to import any or all method names into the user's name
1011 4. Added the ability to initialize CGI objects from strings and
1013 5. Made it possible to initialize CGI objects with filehandle
1014 references rather than filehandle strings.
1015 6. Added the delete_all() and append() methods.
1016 7. CGI objects correctly initialize from filehandles on NT/95 systems
1018 8. Fixed the problem with binary file uploads on NT/95 systems.
1019 9. Fixed bug in redirect().
1020 10. Added '-Window-target' parameter to redirect().
1021 11. Fixed import_names() so that parameter names containing funny
1023 12. Broke the unfortunate connection between cookie and CGI parameter
1025 13. Fixed problems with hidden fields whose values are 0.
1026 14. Cleaned up the documentation somewhat.
1030 1. Added cookie() support routines.
1031 2. Added -expires parameter to header().
1032 3. Added cgi-lib.pl compatability mode.
1033 4. Made the module more configurable for different operating systems.
1034 5. Fixed a dumb bug in JavaScript button() method.
1038 1. Fixed a bug that corrects a hang that occurs on some platforms
1039 when processing file uploads. Unfortunately this disables the
1040 check for bad Netscape uploads.
1041 2. Fixed bizarre problem involving the inability to process uploaded
1042 files that begin with a non alphabetic character in the file name.
1043 3. Fixed a bug in the hidden fields involving the -override directive
1044 being ignored when scalar defaults were passed.
1045 4. Added documentation on how to disable the SelfLoader features.
1049 1. Added support for the SelfLoader module.
1050 2. Added oodles of JavaScript support routines.
1051 3. Fixed bad bug in query_string() method that caused some parameters
1052 to be silently dropped.
1053 4. Robustified file upload code to handle premature termination by
1055 5. Exported temporary file names on file upload.
1056 6. Removed spurious "uninitialized variable" warnings that appeared
1057 when running under 5.002.
1058 7. Added the Carp.pm library to the standard distribution.
1059 8. Fixed a number of errors in this documentation, and probably added
1061 9. Checkbox_group() and radio_group() now return the buttons as
1062 arrays, so that you can incorporate the individual buttons into
1064 10. Added the '-nolabels' option to checkbox_group() and
1065 radio_group(). Probably should be added to all the other
1066 HTML-generating routines.
1067 11. Added the url() method to recover the URL without the entire query
1069 12. Added request_method() to list of environment variables available.
1070 13. Would you believe it? Fixed hidden fields again!
1074 1. Fixed hidden fields yet again.
1075 2. Fixed subtle problems in the file upload method that caused
1076 intermittent failures (thanks to Keven Hendrick for this one).
1077 3. Made file upload more robust in the face of bizarre behavior by
1078 the Macintosh and Windows Netscape clients.
1079 4. Moved the POD documentation to the bottom of the module at the
1080 request of Stephen Dahmen.
1081 5. Added the -xbase parameter to the start_html() method, also at the
1082 request of Stephen Dahmen.
1083 6. Added JavaScript form buttons at Stephen's request. I'm not sure
1084 how to use this Netscape extension correctly, however, so for now
1085 the form() method is in the module as an undocumented feature. Use
1090 1. Added the -override parameter to all field-generating methods.
1091 2. Documented the user_name() and remote_user() methods.
1092 3. Fixed bugs that prevented empty strings from being recognized as
1093 valid textfield contents.
1094 4. Documented the use of framesets and added a frameset example.
1098 This was an internal experimental version that was never released.
1102 1. Fixed a bug that interfered with the value "0" being entered into
1107 1. Added -rows and -columns to the radio and checkbox groups. No
1108 doubt this will cause much grief because it seems to promise a
1109 level of meta-organization that it doesn't actually provide.
1110 2. Fixed a bug in the redirect() method -- it was not truly HTTP/1.0
1115 The changes seemed to touch every line of code, so I decided to bump
1116 up the major version number.
1117 1. Support for named parameter style method calls. This turns out
1118 to be a big win for extending CGI.pm when Netscape adds new HTML
1120 2. Changed behavior of hidden fields back to the correct "sticky"
1121 behavior. This is going to break some programs, but it is for
1122 the best in the long run.
1123 3. Netscape 2.0b2 broke the file upload feature. CGI.pm now handles
1124 both 2.0b1 and 2.0b2-style uploading. It will probably break again
1126 4. There were still problems with library being unable to distinguish
1127 between a form being loaded for the first time, and a subsequent
1128 loading with all fields blank. We now forcibly create a default
1129 name for the Submit button (if not provided) so that there's
1130 always at least one parameter.
1131 5. More workarounds to prevent annoying spurious warning messages
1132 when run under the -w switch. -w is seriously broken in perl
1137 1. Support for the Netscape 2.0 "File upload" field.
1138 2. The handling of defaults for selected items in scrolling lists and
1139 multiple checkboxes is now consistent.
1143 1. Created true "pod" documentation for the module.
1144 2. Cleaned up the code to avoid many of the spurious "use of
1145 uninitialized variable" warnings when running with the -w switch.
1146 3. Added the autoEscape() method. v
1147 4. Added string interpolation of the CGI object.
1148 5. Added the ability to pass additional parameters to the <BODY> tag.
1149 6. Added the ability to specify the status code in the HTTP header.
1151 Bug fixes in version 1.55
1153 1. Every time self_url() was called, the parameter list would grow.
1154 This was a bad "feature".
1155 2. Documented the fact that you can pass "-" to radio_group() in
1156 order to prevent any button from being highlighted by default.
1158 Bug fixes in version 1.54
1160 1. The user_agent() method is now documented;
1161 2. A potential security hole in import() is now plugged.
1162 3. Changed name of import() to import_names() for compatability with
1165 Bug fixes in version 1.53
1167 1. Fixed several typos in the code that were causing the following
1168 subroutines to fail in some circumstances
1171 2. No features added
1173 New features added in version 1.52
1175 1. Added backslashing, quotation marks, and other shell-style escape
1176 sequences to the parameters passed in during debugging off-line.
1177 2. Changed the way that the hidden() method works so that the default
1178 value always overrides the current one.
1179 3. Improved the handling of sticky values in forms. It's now less
1180 likely that sticky values will get stuck.
1181 4. If you call server_name(), script_name() and several other methods
1182 when running offline, the methods now create "dummy" values to
1185 Bugs fixed in version 1.51
1187 1. param() when called without arguments was returning an array of
1188 length 1 even when there were no parameters to be had. Bad bug!
1190 2. The HTML code generated would break if input fields contained the
1191 forbidden characters ">< or &. You can now use these characters
1194 New features added in version 1.50
1196 1. import() method allows all the parameters to be imported into a
1197 namespace in one fell swoop.
1198 2. Parameters are now returned in the same order in which they were
1201 Bugs fixed in version 1.45
1203 1. delete() method didn't work correctly. This is now fixed.
1204 2. reset() method didn't allow you to set the name of the button.
1207 Bugs fixed in version 1.44
1209 1. self_url() didn't include the path information. This is now fixed.
1211 New features added in version 1.43
1213 1. Added the delete() method.
1215 New features added in version 1.42
1217 1. The image_button() method to create clickable images.
1218 2. A few bug fixes involving forms embedded in <PRE> blocks.
1220 New features added in version 1.4
1222 1. New header shortcut methods
1223 + redirect() to create HTTP redirection messages.
1224 + start_html() to create the HTML title, complete with the
1225 recommended <LINK> tag that no one ever remembers to include.
1226 + end_html() for completeness' sake.
1227 2. A new save() method that allows you to write out the state of an
1228 script to a file or pipe.
1229 3. An improved version of the new() method that allows you to restore
1230 the state of a script from a file or pipe. With (2) this gives you
1231 dump and restore capabilities! (Wow, you can put a "121,931
1232 customers served" banner at the bottom of your pages!)
1233 4. A self_url() method that allows you to create state-maintaining
1234 hypertext links. In addition to allowing you to maintain the state
1235 of your scripts between invocations, this lets you work around a
1236 problem that some browsers have when jumping to internal links in
1237 a document that contains a form -- the form information gets lost.
1238 5. The user-visible labels in checkboxes, radio buttons, popup menus
1239 and scrolling lists have now been decoupled from the values sent
1240 to your CGI script. Your script can know a checkbox by the name of
1241 "cb1" while the user knows it by a more descriptive name. I've
1242 also added some parameters that were missing from the text fields,
1244 6. A whole bunch of methods have been added to get at environment
1245 variables involved in user verification and other obscure
1250 1. The problems with the hidden fields have (I hope at last) been
1252 2. You can create multiple query objects and they will all be
1253 initialized correctly. This simplifies the creation of multiple
1255 3. The URL unescaping code works correctly now.
