2 1. Added patch from Stephen Frost that allows one to suppress use of the temp file that is
3 created during uploads.
4 2. Fixed problem noted by Martin Foster in which regular expression meta-character terms
5 in the path information were not quoted, causing URL parsing
6 to fail on URLs that contained metacharacters (such as +).
7 3. More fixes to the url() method.
8 4. Removed "hack to fix broken PATH_INFO in MSII".
12 2. Patch from Steve Peters to default the document type to match the charset.
13 3. Fixed param() so that param(-name=>'foo',-values=>[]) sets the parameter to empty list.
15 Version 3.16 Wed Feb 8 13:29:11 EST 2006
16 1. header() -charset option now works even when the MIME type is not "text".
17 2. Fixed documentation for cookie() function and fastCGI.
18 3. Upload filehandles now only closed automatically on Windows systems.
19 4. Apache::Cookie compatibility fix from David Wheeler
20 5. CGI::Carp->fatalsToBrowser() does not work correctly with
21 mod_perl 2. No workaround is known.
22 6. Fixed text status code associated with 302 redirects. Should be "Found"
24 7. Fixed charset in start_html() and header() to be in synch.
26 Version 3.15 Wed Dec 7 15:13:22 EST 2005
27 1. Remove extraneous "?" from self_url() when URI contains a ? but no query string.
29 Version 3.14 Tue Dec 6 17:12:03 EST 2005
30 1. Fixed broken scrolling_list() select attribute.
33 1. Removed extraneous empty "?" from end of self_url().
36 1. Fixed virtual_port so that it works properly with https protocol.
37 2. Fixed documentation for upload_hook().
38 3. Added POSTDATA documentation.
39 4. Made upload_hook() work in function-oriented mode.
40 5. Fixed POST_MAX behavior so that it doesn't cause client to hang.
41 6. Disabled automatic tab indexes and added new -tabindex pragma to
42 turn automatic indexes back on.
43 7. The url() and self_url() methods now work better in the context of Apache
44 mod_rewrite. Be advised that path_info() may give you confusing results
45 when mod_rewrite is active because Apache calculates the path info *after*
46 rewriting. This is mostly worked around in url() and self_url(), but you
47 may notice some anomalies.
48 8. Removed empty (and non-validating) <div> from code emitted by end_form().
49 9. Fixed CGI::Carp to work correctly with Mod_perl 1.29 in an Apache 2 environment.
50 10. Setting $CGI::TMPDIRECTORY should now be effective.

55 3. Workaround for a bug that appears in Apache2 versions through 2.0.54
56 in which SCRIPT_NAME and PATH_INFO are incorrect if the additional path_info
57 contains a double slash. This workaround will handle the common case of
58 http://mysite.com/cgi-bin/log.cgi/http://www.some.other.site/args, but will
59 not handle the uncommon case of a ScriptAlias directive that adds additional
60 path information to the end of the translated URI.
63 1. Added Apache2::RequestIO, which is necessary for mp2 interoperability.
66 1. Fixed tabindex="0" when using CGI to create forms without a prior start_html
67 2. Removed warning about non-numeric MOD_PERL_API_VERSION.
70 1. update support for mod_perl 2.0. versions prior to
71 mod_perl 1.999_22 (2.0.0-RC5) are no longer supported.
74 1. Fixed typo in mod_perl detection.

84 4. autoEscape() flag is now respected when generating extra
86 5. Tests for *tag start/end generation from Shlomi Fish.
87 6. Support for can() method provided by Ron Savage.
88 7. Fix for lang='' when outputting XHTML.
89 8. Added support for chunked transfer encoding, as suggested by
91 9. Fixed clobbering of row and column headers in tableized radio
92 and checkbox groups, as reported by Nicolas Thierry-Mieg.
93 10. <Label> tags are now associated with form elements, as suggested
94 by accessibility guidelines.
95 11. The <?xml> directive produced by start_html is now turned off by
96 default and the charset is specified in a <meta> directive. Apparently
97 IE6 (and maybe some versions of Opera) were getting confused by this.
98 12. Support for tab indexes.
99 13. Retired the HTML docs. The POD docs are now primary documentation.
100 14. CGI::Carp now correctly detects and handles Apache::Dispatch.
101 15. CGI::Util::utf8_chr now correctly sets the UTF8 flag on 5.006 or
102 higher perls (fix courtesy Slaven Rezic).
107 1. Fixed uninitialized variable warning on start_form() when running
109 2. Fixed CGI::_set_attributes so that attributes with a - are handled
111 3. Fixed CGI::Carp::die() so as to avoid problems from _longmess()
113 4. If HTTP_X_FORWARDED_HOST is defined (i.e. running under a proxy),
114 the various functions that return HOST will use that instead.
115 5. Fix for undefined utf8() call in CGI::Util.
116 6. Changed the call to warningsToBrowser() in
117 CGI::Carp::fatalsToBrowser to call only after HTTP header is sent

121 8. Fixed an extraneous "foo=bar" appearing when extra style
122 parameters passed to start_html;

128 12. Fixed query string stripping in order to handle URLs containing
130 13. During server push, set NPH to 0 rather than 1. This is supposed
131 to fix problems with Apache.
132 14. Fixed incorrect processing of multipart form fields that contain
133 embedded quotes. There's still the issue of how to handle ones
134 that contain embedded semicolons, but no one has complained (yet).
135 15. Fixed documentation bug in -style argument to start_html()
136 16. Added -status argument to redirect().
140 1. Fixed the problem with mod_perl crashing when "defaults" button
145 1. Fix upload hook functionality

165 state saving still working.
166 7. Added code for underreads.
167 8. Fixed misleading description of redirect() and relative URLs in

641 4. Fixed bug which caused strong('CGI') to fail. Be careful to use
642 CGI::strong('CGI') and not CGI->strong('CGI'). The latter will

645 "filehandle as string" feature.

733 correct DTDs, or at least offer the programmer a way to specify
735 2. Split CGI.pm into CGI processing and HTML-generating modules.
736 3. More robust file upload (?still not working on the Macintosh?).
737 4. Bring in all the HTML4 functionality, particular the accessibility
742 1. file uploads failing because of VMS patch; fixed.
743 2. -dtd parameter was not being properly processed.
747 I finally got tired of all the 2.37 betas and released 2.38. The main
748 difference between this version and the last 2.37 beta (2.37b30) are
749 some fixes for VMS. This should allow file upload to work properly on
752 Version 2.37, various beta versions
754 1. Added a CGI::Cookie::parse() method for lucky mod_perl users.
755 2. No longer need separate -values and -labels arguments for
756 multi-valued form elements.

762 6. Added a compile() method for those who want to compile without
764 7. Documented the import pragmas a little better.
765 8. Added a -compile switch to the use clause for the long-suffering
766 mod_perl and Perl compiler users.
767 9. Fixed initialization routines so that FileHandle and type globs
768 work correctly (and hash initialization doesn't fail!).
769 10. Better deletion of temporary files on NT systems.
770 11. Added documentation on escape(), unescape(), unescapeHTML() and
771 unescapeHTML() subroutines.
772 12. Added documentation on creating subclasses.
773 13. Fixed problem when calling $self->SUPER::foo() from inheriting

781 19. Fixed problem with uppercase-only parameters being ignored.
782 20. Fixed vanishing cookie problem.
783 21. Fixed warning in initialize_globals() under mod_perl.
784 22. File uploads from Macintosh versions of MSIE should now work.
785 23. Pragmas now preceded by dashes (-nph) rather than colons (:nph).
786 Old style is supported for backward compatability.
787 24. Can now pass arguments to all functions using {} brackets,
788 resolving historical inconsistencies.
789 25. Removed autoloader warnings about absent MultipartBuffer::DESTROY.
790 26. Fixed non-sticky checkbox() when -name used without -value.
791 27. Hack to fix path_info() in IIS 2.0. Doesn't help with IIS 3.0.
792 28. Parameter syntax for debugging from command line now more
794 29. Added $DISABLE_UPLOAD to disable file uploads.
795 30. Added $POST_MAX to error out if POSTings exceed some ceiling.
796 31. Fixed url_param(), which wasn't working at all.
797 32. Fixed variable suicide problem in s///e expressions, where the
798 autoloader was needed during evaluation.
799 33. Removed excess spaces between elements of checkbox and radio
801 34. Can now create "valueless" submit buttons
802 35. Can now set path_info as well as read it.
803 36. ReadParse() now returns a useful function result.
804 37. import_names() now allows you to optionally clear out the
805 namespace before importing (for mod_perl users)
806 38. Made it possible to have a popup menu or radio button with a value
808 39. link() changed to Link() to avoid overriding native link function.
809 40. Takes advantage of mod_perl's register_cleanup() function to clear
811 41. <LAYER> and <ILAYER> added to :html3 functions.
812 42. Fixed problems with private tempfiles and NT/IIS systems.
813 43. No longer prints the DTD by default (I bet no one will complain).
814 44. Allow underscores to replace internal hyphens in parameter names.
815 45. CGI::Push supports heterogeneous MIME types and adjustable delays
817 46. url_param() method added for retrieving URL parameters even when a
818 fill-out form is POSTed.
819 47. Got rid of warnings when radio_group() is called.
820 48. Cookies now moved to their very own module.
821 49. Fixed documentation bug in CGI::Fast.
822 50. Added a :no_debug pragma to the import list.
826 1. Expanded JavaScript functionality
827 2. Preliminary support for cascading stylesheets
828 3. Security fixes for file uploads:
829 + Module will bail out if its temporary file already exists
830 + Temporary files can now be made completely private to avoid
831 peeking by other users or CGI scripts.
832 4. use CGI qw/:nph/ wasn't working correctly. Now it is.
833 5. Cookie and HTTP date formats didn't meet spec. Thanks to Mark
834 Fisher (fisherm@indy.tce.com) for catching and fixing this.
840 1. Robustified multipart file upload against incorrect syntax in
842 2. Fixed more problems with mod_perl.
843 3. Added -noScript parameter to start_html().
844 4. Documentation fixes.
852 1. Fixed a warning about an undefined environment variable.
853 2. Doug's patch for redirect() under mod_perl
854 3. Partial fix for busted inheritence from CGI::Apache
855 4. Documentation fixes.
859 1. Improved support for Apache's mod_perl.
860 2. Changes to better support inheritance.
865 1. New uploadInfo() method to obtain header information from uploaded
867 2. cookie() without any arguments returns all the cookies passed to a
869 3. Removed annoying warnings about $ENV{NPH} when running with the -w
871 4. Removed operator overloading throughout to make compatible with
872 new versions of perl.
873 5. -expires now implies the -date header, to avoid clock skew.
874 6. WebSite passes cookies in $ENV{COOKIE} rather than
875 $ENV{HTTP_COOKIE}. We now handle this, even though it's O'Reilly's
877 7. Tested successfully against new sfio I/O layer.
878 8. Documentation fixes.
882 1. Automatic detection of operating system at load time.
883 2. Changed select() function to Select() in order to avoid conflict
885 3. Added Tr() as an alternative to TR(); some people think it looks
887 4. Fixed problem with autoloading of MultipartBuffer::DESTROY code.
888 5. Added the following methods:
891 6. Automatic NPH mode when running under Microsoft IIS server.
896 2. Fixed problems that cropped up when useNamedParameters was set to
898 3. Prevent CGI::Carp::fatalsToBrowser() from crapping out when
899 encountering a die() within an eval().
900 4. Fixed problems with filehandle initializers.
904 1. Added support for NPH scripts; also fixes problems with Microsoft
906 2. Fixed a problem with checkbox() values not being correctly saved
908 3. Fixed a bug in which CGI objects created with empty string
909 initializers took on default values from earlier CGI objects.
910 4. Documentation fixes.
914 1. Small but important bug fix: the automatic capitalization of tag
915 attributes was accidentally capitalizing the VALUES as well as the
916 ATTRIBUTE names (oops).
920 1. Changed behavior of scrolling_list(), checkbox() and
921 checkbox_group() methods so that defaults are honored correctly.
922 The "fix" causes endform() to generate additional <INPUT
923 TYPE="HIDDEN"> tags -- don't be surpised.
924 2. Fixed bug involving the detection of the SSL protocol.
925 3. Fixed documentation error in position of the -meta argument in
927 4. HTML shortcuts now generate tags in ALL UPPERCASE.
928 5. start_html() now generates correct SGML header:
929 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
931 6. CGI::Carp no longer fails "use strict refs" pragma.
935 1. Fixed bug that caused bad redirection on destination URLs with
937 2. Fixed bug involving use_named_parameters() followed by
938 start_multipart_form()
939 3. Fixed bug that caused incorrect determination of binmode for
941 4. Spelling fixes on documentation.
945 1. Fixed bug that caused generation of lousy HTML for some form
947 2. Fixed uploading bug in Windows NT
948 3. Some code cleanup (not enough)
952 1. Fixed an obscure bug that caused scripts to fail mysteriously.
953 2. Fixed auto-caching bug.
954 3. Fixed bug that prevented HTML shortcuts from passing taint checks.
955 4. Fixed some -w warning problems.
959 1. New CGI::Fast module for use with FastCGI protocol. See pod
960 documentation for details.
961 2. Fixed problems with inheritance and autoloading.
962 3. Added TR() (<tr>) and PARAM() (<param>) methods to list of
963 exported HTML tag-generating functions.
964 4. Moved all CGI-related I/O to a bottleneck method so that this can
965 be overridden more easily in mod_perl (thanks to Doug MacEachern).
966 5. put() method as substitute for print() for use in mod_perl.
967 6. Fixed crash in tmpFileName() method.
968 7. Added tmpFileName(), startform() and endform() to export list.
969 8. Fixed problems with attributes in HTML shortcuts.
970 9. Functions that don't actually need access to the CGI object now no
971 longer generate a default one. May speed things up slightly.
972 10. Aesthetic improvements in generated HTML.
977 1. Added the -meta argument to start_html().
978 2. Fixed hidden fields (again).
979 3. Radio_group() and checkbox_group() now return an appropriate
980 scalar value when called in a scalar context, rather than
981 returning a numeric value!
982 4. Cleaned up the formatting of form elements to avoid unesthetic
983 extra spaces within the attributes.
984 5. HTML elements now correctly include the closing tag when
985 parameters are present but null: em('')
986 6. Added password_field() to the export list.
990 1. Dumped the SelfLoader because of problems with running with taint
991 checks and rolled my own. Performance is now significantly
993 2. Added HTML shortcuts.
994 3. import() now adheres to the Perl module conventions, allowing
995 CGI.pm to import any or all method names into the user's name
997 4. Added the ability to initialize CGI objects from strings and
999 5. Made it possible to initialize CGI objects with filehandle
1000 references rather than filehandle strings.
1001 6. Added the delete_all() and append() methods.
1002 7. CGI objects correctly initialize from filehandles on NT/95 systems
1004 8. Fixed the problem with binary file uploads on NT/95 systems.
1005 9. Fixed bug in redirect().
1006 10. Added '-Window-target' parameter to redirect().
1007 11. Fixed import_names() so that parameter names containing funny
1009 12. Broke the unfortunate connection between cookie and CGI parameter
1011 13. Fixed problems with hidden fields whose values are 0.
1012 14. Cleaned up the documentation somewhat.
1016 1. Added cookie() support routines.
1017 2. Added -expires parameter to header().
1018 3. Added cgi-lib.pl compatability mode.
1019 4. Made the module more configurable for different operating systems.
1020 5. Fixed a dumb bug in JavaScript button() method.
1024 1. Fixed a bug that corrects a hang that occurs on some platforms
1025 when processing file uploads. Unfortunately this disables the
1026 check for bad Netscape uploads.
1027 2. Fixed bizarre problem involving the inability to process uploaded
1028 files that begin with a non alphabetic character in the file name.
1029 3. Fixed a bug in the hidden fields involving the -override directive
1030 being ignored when scalar defaults were passed.
1031 4. Added documentation on how to disable the SelfLoader features.
1035 1. Added support for the SelfLoader module.
1036 2. Added oodles of JavaScript support routines.
1037 3. Fixed bad bug in query_string() method that caused some parameters
1038 to be silently dropped.
1039 4. Robustified file upload code to handle premature termination by
1041 5. Exported temporary file names on file upload.
1042 6. Removed spurious "uninitialized variable" warnings that appeared
1043 when running under 5.002.
1044 7. Added the Carp.pm library to the standard distribution.
1045 8. Fixed a number of errors in this documentation, and probably added
1047 9. Checkbox_group() and radio_group() now return the buttons as
1048 arrays, so that you can incorporate the individual buttons into
1050 10. Added the '-nolabels' option to checkbox_group() and
1051 radio_group(). Probably should be added to all the other
1052 HTML-generating routines.
1053 11. Added the url() method to recover the URL without the entire query
1055 12. Added request_method() to list of environment variables available.
1056 13. Would you believe it? Fixed hidden fields again!
1060 1. Fixed hidden fields yet again.
1061 2. Fixed subtle problems in the file upload method that caused
1062 intermittent failures (thanks to Keven Hendrick for this one).
1063 3. Made file upload more robust in the face of bizarre behavior by
1064 the Macintosh and Windows Netscape clients.
1065 4. Moved the POD documentation to the bottom of the module at the
1066 request of Stephen Dahmen.
1067 5. Added the -xbase parameter to the start_html() method, also at the
1068 request of Stephen Dahmen.
1069 6. Added JavaScript form buttons at Stephen's request. I'm not sure
1070 how to use this Netscape extension correctly, however, so for now
1071 the form() method is in the module as an undocumented feature. Use
1076 1. Added the -override parameter to all field-generating methods.
1077 2. Documented the user_name() and remote_user() methods.
1078 3. Fixed bugs that prevented empty strings from being recognized as
1079 valid textfield contents.
1080 4. Documented the use of framesets and added a frameset example.
1084 This was an internal experimental version that was never released.
1088 1. Fixed a bug that interfered with the value "0" being entered into
1093 1. Added -rows and -columns to the radio and checkbox groups. No
1094 doubt this will cause much grief because it seems to promise a
1095 level of meta-organization that it doesn't actually provide.
1096 2. Fixed a bug in the redirect() method -- it was not truly HTTP/1.0
1101 The changes seemed to touch every line of code, so I decided to bump
1102 up the major version number.
1103 1. Support for named parameter style method calls. This turns out
1104 to be a big win for extending CGI.pm when Netscape adds new HTML
1106 2. Changed behavior of hidden fields back to the correct "sticky"
1107 behavior. This is going to break some programs, but it is for
1108 the best in the long run.
1109 3. Netscape 2.0b2 broke the file upload feature. CGI.pm now handles
1110 both 2.0b1 and 2.0b2-style uploading. It will probably break again
1112 4. There were still problems with library being unable to distinguish
1113 between a form being loaded for the first time, and a subsequent
1114 loading with all fields blank. We now forcibly create a default
1115 name for the Submit button (if not provided) so that there's
1116 always at least one parameter.
1117 5. More workarounds to prevent annoying spurious warning messages
1118 when run under the -w switch. -w is seriously broken in perl
1123 1. Support for the Netscape 2.0 "File upload" field.
1124 2. The handling of defaults for selected items in scrolling lists and
1125 multiple checkboxes is now consistent.
1129 1. Created true "pod" documentation for the module.
1130 2. Cleaned up the code to avoid many of the spurious "use of
1131 uninitialized variable" warnings when running with the -w switch.
1132 3. Added the autoEscape() method. v
1133 4. Added string interpolation of the CGI object.
1134 5. Added the ability to pass additional parameters to the <BODY> tag.
1135 6. Added the ability to specify the status code in the HTTP header.
1137 Bug fixes in version 1.55
1139 1. Every time self_url() was called, the parameter list would grow.
1140 This was a bad "feature".
1141 2. Documented the fact that you can pass "-" to radio_group() in
1142 order to prevent any button from being highlighted by default.
1144 Bug fixes in version 1.54
1146 1. The user_agent() method is now documented;
1147 2. A potential security hole in import() is now plugged.
1148 3. Changed name of import() to import_names() for compatability with
1151 Bug fixes in version 1.53
1153 1. Fixed several typos in the code that were causing the following
1154 subroutines to fail in some circumstances
1157 2. No features added
1159 New features added in version 1.52
1161 1. Added backslashing, quotation marks, and other shell-style escape
1162 sequences to the parameters passed in during debugging off-line.
1163 2. Changed the way that the hidden() method works so that the default
1164 value always overrides the current one.
1165 3. Improved the handling of sticky values in forms. It's now less
1166 likely that sticky values will get stuck.
1167 4. If you call server_name(), script_name() and several other methods
1168 when running offline, the methods now create "dummy" values to
1171 Bugs fixed in version 1.51
1173 1. param() when called without arguments was returning an array of
1174 length 1 even when there were no parameters to be had. Bad bug!
1176 2. The HTML code generated would break if input fields contained the
1177 forbidden characters ">< or &. You can now use these characters
1180 New features added in version 1.50
1182 1. import() method allows all the parameters to be imported into a
1183 namespace in one fell swoop.
1184 2. Parameters are now returned in the same order in which they were
1187 Bugs fixed in version 1.45
1189 1. delete() method didn't work correctly. This is now fixed.
1190 2. reset() method didn't allow you to set the name of the button.
1193 Bugs fixed in version 1.44
1195 1. self_url() didn't include the path information. This is now fixed.
1197 New features added in version 1.43
1199 1. Added the delete() method.
1201 New features added in version 1.42
1203 1. The image_button() method to create clickable images.
1204 2. A few bug fixes involving forms embedded in <PRE> blocks.
1206 New features added in version 1.4
1208 1. New header shortcut methods
1209 + redirect() to create HTTP redirection messages.
1210 + start_html() to create the HTML title, complete with the
1211 recommended <LINK> tag that no one ever remembers to include.
1212 + end_html() for completeness' sake.
1213 2. A new save() method that allows you to write out the state of an
1214 script to a file or pipe.
1215 3. An improved version of the new() method that allows you to restore
1216 the state of a script from a file or pipe. With (2) this gives you
1217 dump and restore capabilities! (Wow, you can put a "121,931
1218 customers served" banner at the bottom of your pages!)
1219 4. A self_url() method that allows you to create state-maintaining
1220 hypertext links. In addition to allowing you to maintain the state
1221 of your scripts between invocations, this lets you work around a
1222 problem that some browsers have when jumping to internal links in
1223 a document that contains a form -- the form information gets lost.
1224 5. The user-visible labels in checkboxes, radio buttons, popup menus
1225 and scrolling lists have now been decoupled from the values sent
1226 to your CGI script. Your script can know a checkbox by the name of
1227 "cb1" while the user knows it by a more descriptive name. I've
1228 also added some parameters that were missing from the text fields,
1230 6. A whole bunch of methods have been added to get at environment
1231 variables involved in user verification and other obscure
1236 1. The problems with the hidden fields have (I hope at last) been
1238 2. You can create multiple query objects and they will all be
1239 initialized correctly. This simplifies the creation of multiple
1241 3. The URL unescaping code works correctly now.
