ePerl -- Embedded Perl 5 Language

ChangeLog
=========

Changes between 2.2.13 and 2.2.14
---------------------------------
[Bugfixes only]

970727 o Fixed HTTP header parsing: Now beside the header/body
         delimiter "\n\n" also "\r\n\r\n" is recogized correctly.  This
         fixes especially the communication between CGI.pm and ePerl.
         [Thanks to Steve Dodd <dirk@loth.demon.co.uk> for hints and initial
         patches]
       o Fixed examples in Apache::ePerl manual
         [Thanks to Ian Wojtowicz <i@woj.com> for hints]
       o Fixed recognization of CGI situation where GET is used
         instead of POST to send data to ePerl scripts.  [Thanks to Steve
         Dodd <dirk@loth.demon.co.uk> for hint]
       o Added a CREDITS file to give explicit credits to the
         people who contributed stuff in the past
970802 o Replaced build user/host/domain/time determination stuff with a new
         `buildinfo' script I've written for Apache which is more robust.
       o Replaced mkinstalldirs and install-sh with the cleaned up
         versions I've done for Apache 1.3's APACI stuff.
       o Ported to Perl 5.005 where variables start with PL_, etc.

Changes between 2.2.12 and 2.2.13
---------------------------------
[Security and Bug Fixes]

980120 o Fixed construction of URLs inside Apache::ePerl for
         cases where the server port is not 80.  [Thanks to Jim
         O'Quinn <oquinn@fsonline.com> for hint]
980202 o Changed .so generation to be more compatible
980404 o Made etc/newvers more portable
980605 o Fix a minor comparison bug in Apache::ePerl
         [Thanks to Eric Howe <mu@trends.net> for hint]
980705 o Fixed copyright statements by adding 1998 and
         removing the "All Rights Reserved" part because
         this is incompatible with the GPL.
980710 o Fix again a non-trivial-to-fix security bug related to the
         inconsitency way webservers handle QUERY_STRINGs: this time by
         making more exact parameter comparison.  Now we check
         back even the argv[optind] against the provided
         QUERY_STRING, etc. Now the determination of the three
         runtime modes (CGI, NPH-CGI, FILTER) should be
         correct.  [Thanks to Tiago Luz Pinto
         <tiago@EPS.UFSC.BR> who reported this security hole on
         bugtraq]

Changes between 2.2.11 and 2.2.12
---------------------------------
[Bugfix only]

971231 o ARGL! We really need 1998 now: Yesterday
         I've released 2.2.11 with two nasty syntax errors in
         the configure script. Hmmmmm... 1998 is now really
         needed, I think.  [Thanks to Anthony Fok
         <foka@gpu.srv.ualberta.ca> and ??? <djk@tobit.co.uk>
         for quick response and patch]

Changes between 2.2.10 and 2.2.11
---------------------------------
[Bugfix only]

971230 o Activated Perl Locale support for both Perl 5.003
         and Perl 5.004 variants.
       o Fixed owner determination in eperl_main.c: ePerl core
         dumped when the owner of the script does not exists in
         the passwd database.
       o Updated contrib/pkg/ files
       o Updated VERSIONS file

Changes between 2.2.9 and 2.2.10
--------------------------------
[Bugfix only]

971228 o little distribution bug: the asc2c was not run before
         the 2.2.9 release, so it has to be run by the builder
         which is not what was intended.

Changes between 2.2.8 and 2.2.9
-------------------------------
[Bugfix only]

971120 o fixed demo.image.phtml description
971221 o fixed a really nasty fclose() bug in eperl_main.c
         which caused core dumps under Debian GNU/Linux with
         libc6.  [Thanks to <tv@havoc.fi> and Anthony Fok
         <foka@gpu.srv.ualberta.ca> for hints]

Changes between 2.2.7 and 2.2.8
-------------------------------
[Bugfix and Minor Enhancement]

971107 o ported to AIX 4.1.x by adding a fix for Perl's ccdlflags
971108 o again made Apache::ePerl even more complete: added the
         following env variables similar to nph-eperl:
         SCRIPT_SRC_URL, SCRIPT_SRC_URL_DIR,
         SCRIPT_SRC_URL_FILE, SCRIPT_SRC_PATH,
         SCRIPT_SRC_PATH_DIR, SCRIPT_SRC_PATH_FILE,
         SCRIPT_SRC_MODIFIED, SCRIPT_SRC_MODIFIED_CTIME,
         SCRIPT_SRC_MODIFIED_ISOTIME, SCRIPT_SRC_SIZE,
         SCRIPT_SRC_OWNER
       o enhanced the Apache::ePerl status page: now displays
         also the cache size
971116 o fixed shebang mode for webserver environment.  [Thanks
         to J. Douglas Dunlop <dunlop@ionline.net> for hint]
       o added hint to INSTALL file that PerlIO+SfIO is currently
         not supported.
       o fixed HTTP header parsing: now setting of cookies
         (e.g.  via Perl's CGI module) work correctly.
       o fixed HTTP header parsing in Apache::ePerl. Now even
         the special-case "Content-type: ..." works as expected.
971117 o fixed typos in eperl.pod
       o fixed preprocessing for Apache::ePerl
       o overhauled the demo webpages under eg/. Now the
         CGI::Cookie is used an example for CGI.pm.
       o adjusted VERSIONS file

Changes between 2.2.6 and 2.2.7
-------------------------------
[Bugfix and Minor Enhancement]

971102 o reduced memory consumption of Apache::ePerl by
         specificing detailed import flags
       o fixed prototype bug in Parse::ePerl's XS part
         [Thanks to Doug MacEachern <dougm@opengroup.org> for patch]
       o removed the not needed AUTOLOAD facility from
         Parse::ePerl because this causes problems.
         [Thanks to Doug MacEachern <dougm@opengroup.org> for hint]
971104 o added VERSION_LANGUAGE and VERSION_INTERPRETER
         environment variables to Apache::ePerl the same way it is provides
         by the stand-alone program.
971105 o adjusted the URL to the Perl homepage in the PODs.
       o fixed Content-length header generation in Apache::ePerl
       o minor cleanup to Parse::ePerl
971106 o added workarounds to Parse::ePerl for tainted environments
         like the "PerlTaintCheck On" under Apache/mod_perl where
         Parse::ePerl is called from Apache::ePerl.
       o made the Apache::ePerl error page similar to the one nph-eperl
         displays.

Changes between 2.2.5 and 2.2.6
-------------------------------
[Bugfix and Minor Enhancement]

970903 o merged ANNOUNCE and ANNOUNCE.ADDR files
       o slightly fixed comments in eperl_getopt.[ch]
970911 o added mod/README with CPAN module snipppet
       o changed the $VERSION variables to hold a real floating
         point number like 2.0206 instead of 2.2.6
       o updated contrib/pkg/fbsdpkg/ stuff
       o fixed a bug in the preprocessor: filedescriptors were
         not closed for #include directive [Thanks to
         mhalperi@bbnplanet.com for patch]
971024 o fixed configure's Perl version check because of Perl
         5.004_04's changed -v output.
       o added Apache->request($r) to Apache::ePerl for
         Apache::Registry modules like new CGI.pm under mod_perl-1.02.
       o updated PORTING file
       o added GNU long options
       o changed -i (nocase on delimiters) to -n
       o cleaned up source by sorted options
       o now the usage is only displayed on -h/--help
       o now the copyright and disclaimer is displayed on -V, too.
       o now configure removes -D_POSIX_SOURCE from Perl's
         ccflags under IRIX 5.3 because this causes problems with strdup.
       o now configure explicitly removed newlines at the end
         of the determined hostname/domainname pair because these
         would lead to a failure for GNU autoconfs final sed-part.
         [Thanks to <paul@miraclefish.com> for bug report]
       o added another -f test inside configure when trying
         to find a perl binary because when /tmp/perl is
         a directory -x alone fails.
       o added eperl_config.[ch] and moved some code from
         eperl_global to this file.
       o added test for strdup() to configure and a private
         replacement version to eperl_config.c (from FreeBSD 2.2)
         because Ultrix is missing strdup().
         [Thanks to Joerg Lenneis <lenneis@wu-wien.ac.at> for hint]
       o now the XS-Init function in eperl_perl5.c has a variable
         list of newXS() calls which come from the new
         eperl_perl5_sm.h file which itself is generated by
         eperl_perl5_sm.pl. This way we're now really able to
         use static module when no DynaLoader is available.
         [Thanks to Joerg Lenneis <lenneis@wu-wien.ac.at> for hint]
971027 o fixed also PORTING.test for new "perl -v" output
       o changed "prefix" stuff in Makefile.in to make the
         life of our Debian friends a little bit easier... ;_)
       o added Debian stuff to contrib/pkg/dpkg/
       o added workaround in aclocal.m4 for SunOS's braindead "date"
       o sucessfully run PORTING.test on platforms found in PORTING

Changes between 2.2.4 and 2.2.5
-------------------------------
[Bugfix and Minor Enhancement]

970902 o fixed error catching for Parse::ePerl::Precompile.
         [Thanks to Joseph W. Norton <norton@alum.mit.edu> for hint]
970903 o added better support for PerlIO/StdIO. The combination
         PerlIO/SfIO is currently untested and may be broken because
         the I/O redirection for SfIO is very different from StdIO.
       o added Perl I/O layer info to eperl -V
       o added built time/user info to configure and eperl -V

Changes between 2.2.3 and 2.2.4
-------------------------------
[Bugfix and Major Enhancement]

970901 o added more hints to PORTING file
       o fixed a bug in Parse::ePerl for case where $error was undefined
         [Thanks to Joseph W. Norton <norton@alum.mit.edu> for patch]
       o fixed -I option: now it works as expected even for
         cases where you want to add stuff to @INC which is
         needed at _parse_ time.
       o now the webmaster can configure the delimiters and other stuff via
         Apache::ePerl::Config hash from within <Perl>...</Perl> sections in
         Apache. An example is added to the synopsis of Apache::ePerl
         manpage.

Changes between 2.2.2 and 2.2.3
-------------------------------
[Security Bugfix and Minor Enhancement]

970821 o fixed installation section in Apache::ePerl manpage
       o ***** SECURITY BUGFIX *****
         ePerl versions <= 2.2.2 have a heavy security hole when running
         under a webserver's CGI/1.1 interface.   Because ePerl assumed here
         there are not command line arguments. THIS IS WRONG! According to
         the CGI/1.1 spec when an ISINDEX document is used (QUERY_STRING!)
         the query is provided on the command line by the webserver.  So,
         when only one query existed, there was exactly one command line
         argument and ePerl switched to stand-alone runtime mode and all
         CGI-mode restrictions are falling down!!
         ***** SECURITY BUGFIX *****
         [Thanks to Andrew Pimlott <pimlott@abel.MATH.HARVARD.EDU> for
         finding this security bug!]
       o now a chdir is done before the preprocessor is run so relative
         paths in #include directives work as expected.  [Thanks to Marc
         Singer <elf@netcom.com> for patch]

Changes between 2.2.1 and 2.2.2
-------------------------------
[Bugfix and Porting Enhancement]

970804 o removed bad demo.errsync.phtml
970806 o fixed a few spaces in Makefile.in
970807 o removed wrong $AUTOLOAD from Apache::ePerl
       o fixed a few other things in Apache::ePerl and Parse::ePerl
       o added 2.2.1 to VERSIONS file
       o moved the place of the release macros in Makefile.in
         before any targets because some braindead Make variants
         don't like it in the middle of targets.
       o added a new test 09-dynaloader.t for testing if
         dynamic loading works correctly.
       o added error capturing for Parse::ePerl::Evaluate via __DIE__ hook.
       o fixed the PODs
       o moved -lperl at linking after DynaLoader
970808 o fixed configure help string for --with-perl=PATH
       o added missing .eperl extension in eperl_security.h
         [Thanks to Heiko Schlittermann <heiko@os.inf.tu-dresden.de> for hint]
       o added more stuff to INSTALL.APACHE
970811 o fixed wrong coding in setuid check
         [Thanks to SONE Takeshi <ts1@tsn.or.jp> for patch]

Changes between 2.2.0 and 2.2.1
-------------------------------
[Bugfix and Enhancement]

970721 o fixed eg/demo.net.phtml
970727 o optimized the Perl 5 internal stuff in eperl_eperl5.c
         [Thanks to Doug McEachern <dougm@opengroup.org> for patches]
       o added support for Cwd parameter to Parse::ePerl::Precompile and use
         this also in Apache::ePerl when precompiling.
         [Thanks to Michael Lazar <michael@vertex.worldweb.com> for idea]
       o added support for quotation marks and angle brackets in #include
         and #sinclude directives: these are just skipped.
         [Thanks to Karl Wallner <karl.wallner@x3network.net> for idea]
       o now DOCUMENT_ROOT is automatically added to @INC in CGI modes.
         [Thanks to Karl Wallner <karl.wallner@x3network.net> for idea]
       o now Apache::ePerl always uses option "ConvertEntities=1" when
         calling Parse::ePerl::Translate.
         [Thanks to Mike Pheasant <pheasant@gte.net> for hint]
       o fixed demos for strict variables and added both .phtml
         and .iphtml files (same contents!) for easier testing
         with both nph-eperl and Apache::ePerl.
       o added support for generated custom HTTP headers
         to Apache::ePerl.
970801 o added "/eperl" to $libdir for installation
       o now "make install" installs the demo pages into $libdir/eg
       o added PORTING.test script for making porting tests easier
       o changed test for Perl in configure from "test -f" to "test -x"
       o fixed the examples again.
       o fixed a few things in eperl.pod
970802 o enhanced the overwriting of the perl and cc programs
         for the build process. See INSTALL for more details.
       o enhanced PORTING.test to be able to set perl and cc.
       o added overview to INSTALL

Changes between 2.2b9 and 2.2.0
-------------------------------
[Bugfix only]

970706 o added missing eperl_getopt.h include
         for eperl_main.c which caused the compilation
         at least under SunOS 4.x to fail.
       o added more descriptive error message
         to configure when Perl version is to old
       o added hint to INSTALL that the same
         environment have to be used for compiling
         ePerl as for Perl.
970709 o added klduge to support Perl+SFIO where
         fwrite has to be replaced by PerlIO_write
       o enabled ``CC=/path/to/cc ./configure'' again
         for cases where one wants to overwrite the
         used C compiler.
970714 o removed some unused defines in eperl_global.h
         which lead to problems under AIX 4.1.4
       o removed the P_ macros in eperl_proto.h because
         AIX 4.1.4 is not happy about it because of
         PrintError defines which has "...". Should
         be ok without P_ because we need an ANSI
         compiler since the first days.
970715 o changed Perl requirement from 5.00390 to 5.00325
970718 o added ANNOUNCE.ADDR file
       o updated NEWS file and updated ANNOUNCE file
       o updated VERSIONS file
       o slightly adjusted NEWS file
       o created contrib/utils/00README file
       o added the package files to contrib/pkg/
       o updated the demo files

Changes between 2.2b8 and 2.2b9
-------------------------------

970623 o added docs about #elsif to eperl.pod and NEWS file
970628 o added VERSIONS file with ePerl history
       o shit happens: the preprocessor parsing had
         nasty bugs where a string "#include" somewhere
         in the text leads to a total skip of all
         real "^#include" directives :-(

Changes between 2.2b7 and 2.2b8
-------------------------------

970615 o added hint about Options +ExecCGI
         to mod/Apache/ePerl.pm
       o split the ChangeLog file into seperated files
       o added old stuff from 2.1.2 to end of NEWS file
       o created a KNOWN.BUGS file
       o created a INSTALL.NSAPI
       o slightly fixed the POD in mod/Apache/ePerl.pm
       o created a new set of demo files in eg/
       o fixed some README headers
970620 o created a contrib/ dir and initially
         started to write a shtml2phtml script
         which converts (X)SSI to ePerl
       o fixed tabs in top-level Makefile
970622 o changed red colors to blue ones in error page
       o added the new powered-by-ePerl image
         which can be retrieved via URL nph-eperl/powered.gif
       o added del2del script to contrib/
       o added a #elsif to the preprocessor

Changes between 2.2b6 and 2.2b7
-------------------------------

970602 o now etc/newvers always removes /tmp/genopt
         [Thanks to Phil Ritzenthaler <phil@cgrg.ohio-state.edu>
          for hint]
       o now configure determines the full
         operating system id from Perl's Config.pm
970604 o set -Wl,-woff 85 only for IRIX 6.x because
         IRIX 5.x hates this option..
         [Thanks to Ewan McPhail <ewan@epages.iafrica.com> and
          Phil Ritzenthaler <phil@cgrg.ohio-state.edu> for hint]
       o fixed the preprocessor: the inital searching
         of the directives was broken, only worked
         when a specific order was used. So some
         directives were skipped :-(
       o added a #sinclude (secure include) directive
         which is the same as #include but removes
         all begin and end delimiters, so this one
         is a secure way of including stuff from
         foreign servers.
       o rewritten the preprocessor part of eperl.pod

Changes between 2.2b5 and 2.2b6
-------------------------------

970601 o added a #c preprocessor directive
         to be able to comment out stuff
         (even to use "#c #include..." to
         disable an include directive)
         [Thanks to J. Douglas Dunlop for hint]
       o now the preprocessor checks the
         HTTP response code when http://..
         is uses as the file:
         - when 301 and 302 are returned
           it searches for the new URL in the Location-header
           and restarts with this one
         - when a response code other
           than 200 (OK) is returned it fails the same way
           as it fails when a local file it not found:
           with an error.
         [Thanks to J. Douglas Dunlop for hint]
       o removed the Bash check in configure
         because this it not used

Changes between 2.2b4 and 2.2b5
-------------------------------

970530 o fixed perlvers -> perl_vers stuff
       o fixed again problem with VERSION stuff:
         ePerl.pm's were broken (ARGL!)

Changes between 2.2b3 and 2.2b4
-------------------------------

970529 o fixed preprocessor: #include only
         valid at column 0, i.e. at start of line
       o added a test 08 for the preprocessor
       o now any characters are skipped at end
         of #include lines up to the newline
       o added new parsing feature:
         "_" as the last non-whitespace command disables the automatic
         adding of the final semicolon. This is to be able to writeo
         <: if { :> ... <: } :> etc.
       o added new optional(!) parsing feature
         which is per-default disabled(!): "\" directly before a newline
         character outside ePerl blocks prevent the newline to be printed,
         i.e. the line is continued in the output
         This feature can be turned on via new option -L.
       o added new parsing feature:
         when an end delimiter is directly followed by ``//''
         this discards all data up to and including the following
         newline.
       o added three new commands to preprocessor
         which gets converted to ePerl blocks:
         ``#if expr'' -> ``<: if (expr) { _:>//'
         ``#else''    -> ``<: } else { _:>//''
         ``#endif''   -> ``<: } _:>//''
       o imported the patch from ePerl 2.1.2 which
         fixes a problem under non-GCC compilers
         with a semicolon in eperl_security.h
       o removed the sin_len stuff
970530 o !! Essential Change !!
         configure now imports all essential compilation
         flags from Perl's Config.pm, including the compiler.
         This is necessary to make ePerl work even under
         HP-UX and IRIX where they need the special compiler
         and special compiler flags. The point is that
         Perl already determined the correct flags, so
         we can use it.
       o changed C++ style comments in
         eperl_parse.c to C style
       o fixed a missing "int" in eperl_sys.c
       o renamed eperl_getopt.c to original
         eperl_egetopt.c and make the namespace
         clean, i.e. renamed optXXX to egetopt_optXXX.
         This is needed at least for IRIX
       o changes egetopt() slightly
       o replaced the old egetopt() by the GNU getopt()
         because egetopt() was broken under some
         systems like IRIX.
       o option -h now never displays the version
       o added a missing semicolon in mod/Parse/ePerl.pm
       o renamed and fixed mod/Parse/t/04_compile.t
       o now etc/newvers resets the LANG variable
         to prevent LOCALE warnings
       o provided an own copy of perl_eval_pv() which
         is too new. It was introduced in Perl 5.003_97e.
         Now plain old Perl 5.003 will work again.
       o the Perl 5 interface modules can only be
         used with Perl 5.003_90 or higher because
         of the TIEHANDLE stuff which is not working
         in prior releases.
       o fixed update-version target in Makefile.i

Changes between 2.2b2 and 2.2b3
-------------------------------

970521 o fixed NEWS and ANNOUNCE files o spellchecked
         INSTALL, INSTALL.APACHE and eperl.pod
970522 o fixed eperl.pod =back stuff and added a paragraph
         about software leverage.
970523 o added reference for Parse::ePerl and Apache::ePerl
         to eperl.pod
       o changed abstract in all source files
970525 o ** added new option -P for an own #include preprocessor. **
       o added new option -I: same as for "perl" to
         add directories to @INC and preprocessor
970526 o ** added support for URLs to #include **
       o added a kludge to etc/newvers for systems
         like BSDI where no "getopt" program is available
970527 o added Parse::ePerl::Preprocess which is the
         interface to the new preprocessor
       o added six new environment variables:
         SCRIPT_SRC_PATH, SCRIPT_SRC_PATH_DIR and SCRIPT_SRC_PATH_FILE
         SCRIPT_SRC_URL, SCRIPT_SRC_URL_DIR and SCRIPT_SRC_URL_FILE
       o fixed a long-standing bug: temporary files were
         not removed :-(
       o added new option -C for HTML entity conversions
         inside ePerl blocks. This is for people who
         use HTML editors which have now knowledge of ePerl code.
970529 o slightly fixed eperl.pod at some places

Changes between 2.2b1 and 2.2b2
-------------------------------

970518 o fixed ``make install UNINST=1'' case
         for Makefile.PL
970520 o added more POD to Apache::ePerl

Changes between 2.2a2 and 2.2b1
-------------------------------

970505 o again reorganized the source
         code and renamed a lot of
         functions.
       o created modules/ with h2xs
         for a Parse::ePerl module
       o created generation of libeperl.a
         containing shared objects for
         Parse::ePerl
970506 o created a top-level Makefile.PL
         for faking a MakeMaker distribution
970509 o created a Apache::ePerl module
970510 o added option -i for making the
         delimiters case-sensitive in more
         explicit way
970511 o added t/05* to Parse::ePerl
         and made delimiter case variable
970513 o enhanced Parse::ePerl and
         finished Apache::ePerl
970515 o fixed tests 4 and 5 for non-Bash users
         and fixed a char/int problem in eperl_main.c
         and eperl_sys.c
         [Thanks to Jarom Smith <jarom@jarom-indy.prophet.com>]
970516 o finished Apache::ePerl and Parse::ePerl
970517 o added a INSTALL.APACHE which describes the
         installation of ePerl as an SSSL under Apache

Changes between 2.2a1 and 2.2a2
-------------------------------

970504 o removed -s and added -m 755
         to install in configure
       o optimized the parser; no
         ``print "";'' constructs are
         never created which at least slightly
         speeds up processing.

Changes between 2.2a0 and 2.2a1
-------------------------------

970503 o now the begin and end delimiters are searched
         case-insensitive.
       o added -h for displaying the usage list.
         Just to be consequent with options.
       o added leading and trailing whitespaces
         for Perl blocks when translating the source file
         to make the -x display more readable.

Changes between 2.1.1 and 2.2a0
-------------------------------

970502 o added support for '=' prefix: now <:= ... :>
         automatically gets converted to "print ...".  Now one
         can interpolate variables in a more shorter way via
         <?=$variable!> instead of the long <?  print
         $variable; !> (in conjunction with the next
         enhancements)
       o now ePerl is much smarter when converting the ePerl
         blocks, i.e. it now recognizes final semicolons and
         automatically puts one if missing. Now <: cmd;cmd :>
         is also valid.
       o Whitespaces are not only stripped
         from the beginning of a ePerl block. Now
         they are stripped from the end, too.
       o !!CHANGED THE PARSING AGAIN!!
         Now again (as in 2.0.3) ePerl block end delimiters are
         found via plain forward search. No quoted strings are
         recognized.  The reason is that constructs with odd
         number of quoting characters are more often seen than
         end delimiters in quoted string. And one more fact: It
         is easier to escape the end delimiter in a quotes
         string (e.g.  via backslahes) than to rewrite a
         complex construct (e.g.  m|"[^"]+"| !!).
       o added -T (Tainting) and -w (Warnings) options
         which can be used like the same in "perl".
       o added alpha and snap releases to NEWVERS
