C h a n g e L o g o f e P e r l ___________________________________________________________________________ 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 ] 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 instead of the long (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 ___________________________________________________________________________ Changes between 2.1.0 and 2.1.1 ------------------------------- 970501 o added -P option to etc/newsvers o removed \n at SCRIPT_.._CTIME 970502 o replaced the $| = 1 stuff in eperl_perl5.c to the way mod_perl does it [Thanks to Doug MacEachern for patch] o enhanced the SetUID-based UID/GID checking: now in eperl_global.h is an option DO_ON_FAILED_STEP which either forces ePerl to error on any failed checks or go on but finally don't do the UID/GID switching o moved the security definitions from eperl_global.h to a new eperl_security.h and changed the references in eperl.pod Changes between 2.1b8 and 2.1.0 ------------------------------- 970426 o removed more obsolete @logfile@ stuff o again revised eperl.pod o !! CHANGED LICENSE !! NOW ePerl IS DISTRIBUTED AT THE TERMS OF EITHER THE GPL OR THE ARTISTIC LICENSE LIKE THE Perl 5.0 INTERPRETER ITSELF o fixed /tmp/x usage in configure o created PORTING file o tested ePerl on various platforms o made seteuid/setegid configureable via GNU autoconf for HP/UX and others o made the include files in eperl_globa.h conditional o made the -O2 conditional for GCC only Changes between 2.1b7 and 2.1b8 ------------------------------- 970425 o fixed installation manpath o fixed a security hole: the effective uid/gid have to be eliminated independend of mode and uid switching o fixed some typos in eperl.pod o rewritten the NEWS file o renamed the options: -D => -d, -E => -D (more intuitive) -b => -B, -e => -E (prevent conflicts) o fixed the order of command line option descriptions o removed the @logfile@ stuff from Makefile Changes between 2.1b6 and 2.1b7 ------------------------------- 970425 o fixed error page colors o changed some aux files: NEWS, TODO o added .cgi to allowed extensions for using shebang CGI/ePerl scripts o added more clear info about shebang to eperl.pod o fixed more bugs in eperl.pod o removed the exit on debug o finished the test suite o slightly fixed the usage output o added support for HEAD requests in case the server does not do it for us o documented provided env variables o created new isotime() function for SCRIPT_SRC_MODIFIED_ISOTIME variable o removed eperl_log.c because this will be used in later versions only Changes between 2.1b5 and 2.1b6 ------------------------------- 970414 o slightly changed the error message page 970418 o created -c for syntax check like "perl -c" o now the default delimiters are for CGI modes and <: ...:> for Filter mode o removed the delimiters defs in eperl_global.h but added a table to eperl.pod o completely rewritten the setuid security stuff !! o added security information to eperl.pod o now -x does something useful: it outputs the internally generated Perl script to /dev/tty and exits Changes between 2.1b4 and 2.1b5 ------------------------------- 970404 o now when used as a Unix filter the exit code is != 0 on error while for CGI scripts it is still 0 (needed to make the webserver happy and to force him to accept your HTML error page). o now prints the error message on stderr instead of stdout in Unix filter mode o fixed "make distclean", now t/Makefile is also removed. Changes between 2.1b3 and 2.1b4 ------------------------------- 970403 o fixed a bug in the b3 distribution: autoheader was not run, so to _compile_ ePerl GNU autoconf was needed. :-( o slight adjustments to eperl.pod Changes between 2.1b2 and 2.1b3 ------------------------------- 970402 o starting with Perl 5.003_96 the dXSUB_SYS define is empty. Removed the call and the gcc -Wall kludge from eperl_perl5.c o fixed etc/newvers o add "none" to configure DynaLoader check Changes between 2.1b1 and 2.1b2 ------------------------------- 970330 o reduced the logo GIF image in size to fit betteri into the browser window. The reduced one also has 10 KB less bytes. o made the Error HTML page nicer o removed the not used -a (age) option Changes between 2.1b0 and 2.1b1 ------------------------------- 970326 o added "-o file" to the usage message o when running as a Unix filter the current working directory is restored before the final outputfile (-o) is created. o documented that "-o outputfile" is relative to source file dir when runtime mode is CGI or NPH-CGI o added new-betalevel to Makefile.in Changes between 2.0.3 and 2.1b0 ------------------------------- 970322 o released as 2.1b0 for first test 970310 o added --with-perl=/path/to/perl option to ./configure to force a specific perl 970302 o removed getdate.c stuff :-( o added more tests o changed aux dir to etc for porting to WinNT :-( 970228 o debugged and cleanup up eperl_parse.c o fixed the core-dump under SunOS which comes from SunOS' non-POSIX vsprintf(). o removed the sdbm and md5 stuff because this should be introduced in 3.0 later only. o removed brainfile stuff o fixed another coredump in eperl_parse.c o fixed mode determination and mode-dependend error message 970227 o debugged and cleanup up eperl_parse.c 970226 o added dmalloc support for debugging 970224 o changed sprintf stuff to more portable variant in eperl_main.c o now autoconf checks for memmove and if not found eperl_parse.c uses bcopy. 970219 o changed bool checking to Autoconf stuff 970216 o ported to Linux: now bool is defined, prefix was replaced by AC_prefix to avoid collisions and the ccdlflags from Perl are used which need to be -rdynamic under Linux. Now ePerl compiles out of the box on Linux and runs fine, even with dynamic loading. 970210 o added getdate() code o added --enable-brainfile=/path/to/brainfile which sets the brain file where timestamps and md5 etc. are stored. o added -a option to set an age 970209 o added MD5 code o added SDBM code 970207 o changed -c and -s options to -m c and -m f o adding -m n for NPH/CGI, -m c is no only CGI o added stdin support via "-" and tmpfiles o added automatic tmpfile support with remove on interrupts or errors o now the old tempfiles are also created with new mechanism o added -o option for specifying an explicit outputfile instead of stdout o greatly imporved the manpage and brroght it to the latest status o created a test suite with Perl Test::Harness o now ePerl also accepts an empty file o added a security logfile which can be optionally enabled via "--enable-logfile=/path/to/logfile" at compile time. o added configure support for debug compilation via --enable-debug. This adds -g -ggdb3 to the CFLAGS and LDFLAGS and prevents the executable from being stripped. o removed the old doc/ subdir with the old FAQ and About file. 970206 o removed the generation of libeperl.a o added a real installation target to Makefile o removed eperl_parse.h, because it is still replaced by the generated eperl_proto.h o added -V option which now displays the compile parameters o removed the .. tags from error output because for the stand-alone version is looks bad. o added experimental TAINT...TAINT_NOT around perl_run. o added -d option to set real Perl variables and not just $ENV{'...'}; 970128 o added support to configure for Perl snapshot releases named 5.003_XX. o added a first security check: If operating in NPH-CGI mode the source file has to be one of the predefined valid file extensions. o now when ePerl runs as a setuid program (seteuid = 0) it switches to the uid/gid of the file owner 970127 o added -D option to set environment variables. (this is needed for my WML project where in pass 3 eperl gets called via -D...) o added -k option to keep CWD. (this is needed for my WML project where ePerl should not chdir to the /tmp/xxx files). 970118 o make the BEGIN/END_DELIMITER strings variables which now can be set via -b and -e (this is needed for my WML project where I use two variants of embedded Perl blocks) 970107 o fixed this changelog file o added test directory o cleanup of Makefile o removed obsolete prototypes in eperl_lib.h o cleaned up eperl_global.h o make eperl_getopt.[ch] gcc -Wall clean o added support for shebang usage, i.e. you can use #!/path/to/eperl at the top of your pages and use them as a CGI script now. ePerl will ignore the shebang line. o moved the system IO and env functions out to new eperl_sys.c o renamed eperl_lib to eperl_parse o Hups! all references to the CGI/1.0 standard were wrong, it actually is CGI/1.1... 970106 o added stand-alone interpreter with options o added -x and -v options o added README and LICENSE display o now ePerl reads the file from stdin if the argument is "-" o added a ePerl manual page for the stand-alone interpreter ___________________________________________________________________________ Changes between 2.0.2 and 2.0.3 ------------------------------- 970104 o added some documentation from the webpages to misc/doc/ o added a FreeBSD ports area to the webpages Changes between 2.0.1 and 2.0.2 ------------------------------- 970104 o remove of the temporary files were disabled for debugging purposes. Fixed. Changes between 2.0.0 and 2.0.1 ------------------------------- 970103 o removed unused variables Changes between 1.0 and 2.0.0 ----------------------------- 970102 o ePerl now supports the Perl 5 DynaLoader interface for dynamic linking and loading of shared modules. This provides ePerl with the complete power of the underlying Perl 5 installation, including the shared objects. o ePerl now runs as NPH-CGI/1.1 script, i.e. as a Non-Parsed-Header CGI-script. This means that it is able to create its own HTTP header. Implications of this include: - To create HTTP headers just put them on the first lines in your script as plain text or just generate them on the fly by a ePerl block at the beginning of your script. With this feature you can for instance write pages which create images instead of HTML code. - If no headers were created by the script, it outputs it with MIME-type "text/html", including an additional calculated "Content-Length" header. - It automatically adds "Date" and "Server" headers. o ePerl now saves and checks the STDERR output of the script. If this contains data this implies an error and leads to the display of the error HTML page, displaying the STDERR output. o ePerl now saves the STDOUT output of the script (the real contents). This implies that it can calculate the Content-Length or ignore it if STDERR was created and the error page have to be displayed. o Additional environment variables will be set by ePerl prior to the execution of the bristled Perl blocks: SCRIPT_SRC_SIZE ....... the byte size of the original source file SCRIPT_SRC_MTIME ...... the integer value of the last modify time SCRIPT_SRC_MTIME_FMT .. the formatted string of the last modify time SCRIPT_SRC_OWNER ...... the owner of the original source file VERSION_INTERPRETER ... the ePerl version string VERSION_LANGUAGE ...... the Perl version string o The ePerl sources were split into distinct peaces to allow further development, e.g. a standalone program or a Apache API module. ___________________________________________________________________________ Changes between 1.4 and 1.5 --------------------------- 9609xx o started with the work to split the ePerl functionality into a library and create a stand-alone CGI-program and a Apache module which use this library. Changes between 1.3 and 1.4 --------------------------- 960906 o changed source from PATH_INFO to PATH_TRANSLATED o cleanup the sources and released it the first time officially on the Web Changes between 1.2 and 1.3 --------------------------- 960622 o created WWW pages o changed all old EPL references to ePerl o added a lot of comments to the source o made the begin and end delimiters variable o changed the end delimiter from ">" to "!>" because ">" makes problems if it occurs inside the ePerl block Changes between 1.1 and 1.2 --------------------------- 960510 o created GNU autoconf files, Makefiles, etc. Changes between 1.0 and 1.1 --------------------------- 960415 o fixed a bug in the escape code: more chars have to be escaped! Changes between *GENESIS* and 1.0 --------------------------------- 960323 o adapted for Apache 1.1b0+ak 960310 o *GENESIS* ___________________________________________________________________________
