Revision history for Perl extension CIPP.

2.40 Fri Nov  9 2001, joern
	Bugfix:
	- <?REQUIRE ISA> was broken and is still not documented
	  in CIPP::Manual. If you provide the ISA switch and inside
	  a <?MODULE>, this module inherits from the loaded module.

2.39 Tue Oct 30 2001, joern
	Bugfix:
	- upload files are not closed by CIPP, instead they're
	  seeked to the beginning, thus mulitpile saving the
	  same file is possible (even if the same file was
	  uploaded via different upload fields in one request)

2.38 Sat Oct 13 2001, joern
	Bugfix:
	- CGI::CIPP did not recognize the include_sub directive
	  correctly
	- Apache::CIPP prints now many "</table>" before giving
	  error messages. This prevents invisible error messages
	  inside tables which are not finished due to the
	  exception.

2.37 Tue Jul 24 2001, joern
	Bugfix:
	- removed unwanted debugging output on database close from
	  CIPP::Runtime. Note: you must install this CIPP::Runtime
	  version (0.39) on all your production systems to get rid
	  of the debugging messages.

	Features:
	- <?GETURL> support for new.spirit generic file type and
	  jar file types

2.36_04 Mon May 14 2001, joern
	INTERNAL BETA RELEASE
	Bugfix:
	- chdir to the base dir of the CGI program did not work,
	  because it was exectued too late. Thus programs did not
	  work, if the actual working directory differed from
	  the installation directory.
	- documentation is uptodate
	
	Incompatible Change:
	- The shortcut syntax for includes <?x.include.this>
	  is not deprecated anymore. It is completely forbidden.

	Features:
	- new CIPP command
	  <?>arbitrary perl expression to be printed<?/>

	  This makes it possible to write things like this
	  with less syntax overhead:

	  <?>$object->get_attribute<?/>

	  The official Perl solution for this:

	  ${\( $object->get_attribute )}

	  is really ugly, and the CIPP way
	  
	  <?PERL>print $object->get_attribute;<?/PERL>
	  
	  too long ;)


2.36_03	Mon May 14 2001, joern
	INTERNAL BETA RELEASE
	Bugfix:
	- <?REQUIRE> did not work for modules outside the own
	  project

2.36_02	Mon May 14 2001, joern
	INTERNAL BETA RELEASE
	Bugfix:
	- CIPP::Runtime threw warnings on program exit:
	  "commit ineffective with AutoCommit enabled ... "
	- "make test" always failed

2.36_01	Mon May 14 2001, joern
	INTERNAL BETA RELEASE
	Bugfix:
	- Bugzilla Bug #132:
	  - fixes some mod_perl bugs. If several new.spirit projects
	    are installed under one mod_perl instance some side effects
	    occured (establishing wrong database connections, loading
	    of wrong base configs)
	  - establishing the correct @INC path failed under mod_perl
	    (subsequent requests only had the standard @INC, all project
	     specific @INC entries disappeared)

2.35	Wed Mar 28 2001, joern
	Bugfix:
	- under new.spirit <?GETURL> did not work on cipp-html objects
	  with special file extensions (js, css)

2.34	Wed Mar 28 2001, joern
	Bugfix:
	- an <?EXIT> inside a <?CATCH> block causes that the catched
	  exception was thrown on exit
	- Include call code for Include Subroutines
	  was totally broken

2.33	Tue Mar 27 2001, joern
	- <?SAVEFILE> throws more detailed exception, when
	  the upload file parameter is not defined

2.32	Mon Mar 26 2001, joern
	- CIPP::Runtime now gives slightly more information on database
	  connection faults
	- fixed a bug in CIPP::Include. Include parameters which contained
	  double quotes produce syntax errors (in Include Subroutine mode)

2.31	Fri Mar 23 2001, joern
	- fixed a bug in <?SQL VAR=" $a, $b"> parsing. Leading
	  whitespace produces incorrect perl code.

2.30	Sat Mar 16 2001 joern
	- now Apache::CIPP and CGI::CIPP are integrated into the
	  CIPP distribution. Extra downloading and installation
	  is not neccessary anymore. The documentation is actually
	  not perfectly merged, so some READMEs and PODs contain
	  redundant information. Please be patient: a new documenatation
	  is on its way! ;) Anyhow: this adresses only installation
	  notes. The CIPP language itself is good documented through
	  the CIPP::Manual POD module.
	  
	- the experimental implementation of Subroutine Includes
	  is now less experimental ;) You can control this feature
	  through the Apache or CGI::CIPP configuration parameter
	  'include_subs'. The future will bring CIPP module generation
	  with all that caching stuff for Apache::CIPP and CGI::CIPP
	  environments, and not only under new.spirit.
	  
	  Note:
	  =====
	  Before enabling Subroutine Includes, delete your CIPP cache
	  directory, because the internal file structure has changed.

	- the new configuration parameter 'stats' controls collection
	  of runtime profile statistics. You can see how much time
	  your programs *and* Includes spend. Refer to the Apache::CIPP
	  manpage for a brief description of enabling this feature.
	  
	  Note:
	  =====
	  Statistics are collected on a per process base, so this only
	  functions for mod_perl or SpeedyCGI environments. Pure CGI
	  environments (new.spirit or CGI::CIPP) are currently not
	  supported, but this may change in future.

2.29	Mon Mar 12 2001 joern
	- Bugfix:
	  Due to a bug inside the CIPP Include Cache machanism a
	  <?!HTTPHEADER> command used by an Include did not
	  work, if you do a new.spirit "Project Compilation"
	  (only for the *first* processed object, which includes
	  this Cache include)

2.28	Wed Mar 07 2001 joern
	- updated CIPP::Manual

2.27	Mon Mar 05 2001 joern
	- the BEGIN block at the top of each CGI program is marked
	  with a # sign to tell new.spirit not to strip it off for
	  syntax checking

2.26	Mon Mar 05 2001 joern
	- experimental implementation of Subroutine Includes. Includes
	  are processed to subroutines, instead of copying the content
	  of the include into the actual document. Programs need much less
	  memory and can speed up to 20% in a mod_perl environment.
	  Currently this works only in Apache::CIPP and CGI::CIPP
	  environment. To enable this feature, set $CIPP::INCLUDE_SUBS
	  before CIPP->new(), until this feature is "official".
	- a new command: <?DUMP $var ...>. Uses Data::Dumper to dump
	  the listed variables to STDOUT, encapsulated in a <pre> block.
	- added a new option to the SQL commands: DBH. If a DBH option
	  is present, the given variable name is used as the database
	  handle for this operation. It is not possible to use the DBH
	  and DB option in combination.
	  
	  The following SQL related commands recognize the DBH option:
	  
	  <?SQL> <?COMMIT> <?ROLLBACK> <?AUTOCOMMIT> <?DBQUOTE>

2.25	Wed Feb 28 2001 joern
	- fixed html formatting bug in error formatting function

2.24	Sun Feb 25 2001 joern
	- ported dynamic database connection feature to Apache::CIPP
	  and CGI::CIPP. This now works under all CIPP environments.

2.23	Wed Feb 21 2001 joern
	- error formatting in case of a CIPP/new.spirit module name
	  clashing was messed up, but there are still problems in
	  error formatting (very seldom, so I don't hurry ;)

2.22	Mon Feb 19 2001 joern
	Bugfix:
	- <?GETURL> did not work for .png images

2.21	Fri Feb 16 2001 joern
	Bugfix:
	- <?GETPARAM>, <?GETPARAMLIST> and <?SAVEFILE> did not work
	  inside of CIPP modules

2.20	Thu Feb 15 2001 joern
	- <?HTML> forces the preprocessor to generate print statements
	  even in 'cipp/dynamic' mode.

2.19	Thu Feb 15 2001 joern
	- database connections are now establisjed dynamically.
	  In earlier version all required database connections found
	  in the program were established at the top of the program.
	  Now the connection is made on the fly, where needed.

	- WARNING: this code is not tested neither under Apache::CIPP
	           nor CGI::CIPP environment and likely will fail
		   there. Please dont use CIPP 2.19 with these modules.

2.18	Wed Feb 14 2001 joern
	- Bugfix: alternate database names did still not work
	  with new.spirit 2.x

2.17	Mon Feb 12 2001 joern
	- Bugfix: alternate database names did not work with new.spirit 2.x
	- Naming of x.bla.db does now work, project name does not matter

2.16	Tue Feb 11 2001 joern
	- (hopefully) final bug fixing in http header generation:
	  The project wide configured default HTTP header
	  was printed, although 'cipp/dynamic' is set and no
	  <?!HTTPHEADER> occurs.
	- also a HTTP header was printed, if the 'print_content_type'
	  attribute was set to false (e.g. in case of generating
	  a static HTML page with new.spirit)

2.16_01	Tue Feb  6 2001 joern
	- fix for usage with new.spirit 2.x. The new style .m files
	  for object properties broke the object source file resolution
	  algorithm

2.15    Tue Nov 28 2000 joern
	- added <?INPUT TYPE="image" SRC="x.gifs.picture">
	- fixed Bug in HTTP Header generation in case of
	  "cipp/dynamic" mode

2.14_04 Fri Oct 13 2000 joern
	- Bugfix: a broken http header was printed when
	          generating CIPP-HTML files with new.spirit 2.x

2.14_03 Sun Aug 13 2000 joern
	- Include cache works now Ok in Apache::CIPP
	  environments, if same named include occur
	  in different virtual hosts

2.14_02 Tue Aug  8 2000 joern
	INTERNAL BETA RELEASE PRE 2.15
	- this version represents a huge merge of the two CIPP
	  trunks 2-0-9-patches and 2.14_01.

	  2-0-9 implements many mod_perl fixes for using
	  generated CGI programs (new.spirit) under mod_perl.

	  2.14_01 adds many features to the CIPP language
	  and has some internal optimizations.

	- the CIPP/DB_DBI.pm module comes mainly from the
	  2.14_01 trunk. Only some fixes added to the 2-0-9
	  revision in the 2-0-9-patches trunk are added
	  manually to 2.14_01, because 2.14_01 got a major
	  internal redesign of the method interfaces.

	- added STICKY Feature to
		<?INPUT TYPE="checkbox">
		<?INPUT TYPE="radio">

	- added new CIPP Tags
		<?SELECT>
		<?OPTION>
		<?!PROFILE>	(experimental, interface may change)
		<?!HTTPHEADER>
		<?#>

	- Thanks go to Martin H. Sluka <martin@sluka.de> for
	  his suggestion about the STICKY feature.

	- Change syntax of <?GETURL> command. See documentation
	  CIPP::Manual for details
	
	- <?AUTOPRINT> is depreciated. Use <?!AUTOPRINT> instead.

2.14_01  Tue Mar 29 2000 joern
	INTERNAL BETA RELEASE
	- disconnect before connect to prevent rollback
	  ineffective error messages in mod_perl context

2.13	 Mo  Mar  6 2000 joern
	- new release, published to CPAN

2.13_03  Fr  Nov 26 1999 joern
	INTERNAL BETA RELEASE
	
	- Bugfix: debugging output in Apache/CGI Modus crashed

2.13_02	 Fr  Nov 26 1999 joern
	INTERNAL BETA RELEASE
	
	- many CIPP commands were dependent from the context, e.g.
	  it was impossible to use <?GETURL> in a <?PERL> context.
	  Now nearly all CIPP commands can be used in any context,
	  only inside a <?VAR> command context no other CIPP commands
	  can be used (which of course would make no sense ;)
	- new CIPP command <?HTML> to switch from <?PERL> context
	  into HTML context
	- now it is possible to nest <?SQL> commands, if the underlying
	  database engine supports multiple executed statement handles


2.13_01  Thu Nov 25 1999 joern
	INTERNAL BETA RELEASE

	- CIPP debugging source output enhanced: a summary of
	  errors is printed, with hyperlinks to the appropriate
	  sections of the highlighted source code output, so
	  you can navigate through your source code
	- new internal method to get the top level used objects
	  of a CIPP program (the existent methods always flatten
	  the dependency hierarchies)
	- new method for formatting Perl syntax error output, incl.
	  referencing to the corresponding CIPP lines
	- new CIPP command <?MODULE>
	- new CIPP command <?USE>
	- command <?LIB> is depreciated
	- DBI code generator has been slighlty optimized
	- some CIPP global variables of the generated Perl programs
	  did change. Currently there is a compatability patch active,
	  so existent applications (e.g. new.spirit 1.x, Apache::CIPP
	  and friends) need no change. Future releases will depend
	  on the new interfaces. Actually only new.spirit 2.x uses
	  the new style interface.

2.12  Sat Oct 09 1999 joern
	- added a workaround for Informix databases. After connecting
	  to the database, a "set lock mode to wait" is executed,
	  because some Informix databases do not wait on a lock. Instead
	  nothing happens, even no exception is thrown. :(
	  I will add this as an official feature in the near future,
	  called 'initial sql statement' per database. This is more
	  flexible than this hardcoded workaround.

2.11  Thu Sep 30 1999 joern
	- the Changes log has restarted with this version
	- CIPP has now multilanguage support. Error messages
	  are in english or german.
	- the documentation is translated to english. It is not
	  part of this distribution. Please download the package
	  CIPP-Doc from CPAN.


The previous section was in german language only and rather long,
so it is omitted here.
