1.2b9 (BETA) 10. Sept 1999
- Fixed a problem with loading Apache::Session 1.01, when
Apache::Session 0.17 is not installed. Spotted by Volker Hess.1.2b8 (BETA) 9. Sept 1999
- Fixed behaviour of <INPUT>. <INPUT> now does not overide
VALUE="" with the value from %fdat. This seems to has been
broken, since a couple of versions and the fix may break
pages that depends on that wrong behaviour. Anyway I have
to fix it before the release version is out!
- Added a patch (and a FAQ) from Jens-Uwe Mager, so Embperl compiles
and links on AIX.
- Fixed error in URL unescaping, spotted by Hartmut Palm.
- _WINSOCK2API_ gets defined on Win32, when compiling with
Apache 1.3.9. Spotted by Randy Korbes.
- Win32 test uses also embpexec.test.pl (instead of .bat),
so cgi test runs also with Apache 1.3.9. Spotted by Randy Korbes.
- Fixed problem with EMBPERL_SESSION_ARGS that splits the arguments
wrong when, for example, the DataSource contains a '='. Spotted by
Vince Galloway.
- Fix a memory leak which eats one SV per <OPTION> tag, introduced
in 1.2b6.
- Fix a problem that meta commands also recognized as html tags, i.e.
now <if x> is no longer the same as [$ if x $]. Spotted by Danielle Gallo.
- German documentation (IntroD.pod, FeaturesD.pod and EmbperlD.pod)
are now included in the distribution.1.2b7 (BETA) 30 Aug 1999
- Embperl works now with Apache::Session 1.01
(1.01 _not_ 1.00 or below!)
- Cookie for session id is only send the first time and not
resend if it's already known by the browser. Suggested
by Roman Maeder.
- Fixed a SIGSEGV that occurs with $optRawInput = 1 and a
value is in %fdat, but not in the input html tag. Spotted
by Robert. 1.2b6 (BETA) 19 Aug 1999
- When call another page via Execute EMBPERL_VIRTLOG will
automaticly set to the same value as the in the calling page
- Add parameter 'firstline' to specify the linenumber of the
first line in the input
- Defined missing DECLINED constant for non mod_perl environement
Spotted by James Elson.
- Inside of an A tag URL escaped characters are translated back
to their ascii aquivalent inside of perl code, before the code
is executed. This avoid problems with HTML editors, which
changes space to %20 inside an URL.
- '%' is escaped to %25 inside of URLs
- Inside the A tag only the HREF attribute is URL escaped, instead
of the whole tag.
- The SRC attribute of embed, frame, iframe, img, layer now are
also URL escaped.
- Giving a an array refernce inside an URL, cause Embperl expand
it to URL parameter syntax (i.e. [+ \@A +] becomes A=1&B=2, when
@A = (A, 1, B, 2) ).
- Embperl checks now for unclosed metacommands (if, while etc.) and
unclosed HTML tags (table etc.). Suggest by Todd Eigenshink.
- Fixed a problem when file was not found, which causes in some cases
a SIGSEGV.
- Added new configuration directive EMBPERL_MAIL_ERRORS_TO. If set
all error messages will be send to the given address.
- input_/output_func parameter can take a code reference as
argument. Based on a patch from Jon Tobey.
- Set force PERL_DL_NONLAZY to zero, so make test does not fail
if dynaloader was initialized with PERL_DL_NONLAZY set.
Patch from John Tobey.
- [$ foreach $i(x..y) $] does not require a space before the (
anymore. Suggested by Jonny Cavell.
- select <option value="a & b"> works now correctly. Spotted by
Rick Welykochy.
- Fixed SegFault when parameter input => is numeric. Spotted by
Cliff Rayman.
- Added option optNoUncloseWarn, which disables the warnings
about unclosed if, while, table etc.1.2b5 (BETA) 5 July 1999
- Renamed __strdup and __strndup so there are no duplicate
symbols when compiling with glibc. Spotted by Michael Hall.
- Removed some debugging message from the logfile output.
- Correct some wrong table entries for html escaping of some
characters like §
- Added optReturnError which causes Embperl to return an
error code and let the calling programm (i.e. Apache)
handle the error. This is necessary to use the
ErrorDocument directive together with Embperl. Spotted by
Michael Smith.
- Fixed the problem that the output of Execute inside a table
didn't come out when optEarlyHttpHeader was set. Spotted by
Chris Alexander.
- %fdat of a Execute will not be overwritten anymore when the
%fdat of the main request was empty. Spotted by Chris Alexander.
- fixed a small memory leak which was caused by not releasing
memory space for the cookie-name/-domain etc.
- added the missing -T switch to embpexec.test.bat, which caused the
taint test in cgi mode to fail on win32
- Added epchar.c.iso-latin-2 from Jiri Novak, which contains the correct
escaping for the iso-8859-2 (iso-latin-2) character set. You may use it
to replace the standard epchar.c
- Added new metacommand [$ sub <name> $] and [$ endsub $] which allows
you to define blocks of code an call them mulitple times inside a page,
either a creating a subrequest Execute('#<name>') or by calling them
directly as a perl subroutine [- <name> -]. Read the docs for more
information on the details and differences.
- Added new parameter "import" to Execute, which let's you import subs
(defined with [$sub <name>$]) into the current page.
- @ffld is filled with 'values %fdat' if the ffld parameter in the call
to the Execute funtion is missing.
- Filedata will held into memory until the end of the request, so a
second call to Execute for the same file will not reread the data
from disk.
- Added emacs/embperl.el. It's a emacs minor mode for Embperl written
by Erik Arneson
- Output of dbgShowCleanup is now sorted by name
- Update the Faq.pod with new Q&A and removed obsolete Q&A
- Made Makefile.PL more smarter in DSO situations. It detecteds now
which of the needed Apache modules are linked staticly and places
neccessary LoadModule statements in the httpd.conf for make test.
This way make test should work also where all modules linked at
runtime, like on RedHat 6. With help form James H. Thompson.
- Makefile.PL ask´s now if it can´t find any modules. On win32
it will not try to guess (the maybe wrong) path anymore.
- Added possibility to get the the uploadInfo from CGI.pm
(e.g. ${${$fdat{upload}}} -> {'Content-Type'} will return the
content type). Requested by Brian Reichert.
- Catch die of CGI.pm when it hit's a 'Malformed multipart POST'.
Spooted by Chris Alexander.
- Add optKeepSrcInMemory which tells Embperl to keep the source
file in memory and not reload it on every request
- Added the possibility to use recursive calls to Execute.
NOTE: You can create local variables via [* local $foo ; *]
- Reworked the cleanup. Now imported values from other modules
left unchanged. This solves problems with using modules
inside Embperl pages, which exports some global variables.
- Added the %CLEANUP hash. Put variables into with should be
additional cleaned up ($CLEANUP{'var'} = 1) or which shouldn't
cleaned up ($CLEANUP{'var'} = 0)
- Special handling for DBIx::Recordset objects, so it's sure
they are really get destroyed
- fixed a problem with dynamic tables, that occurs when you
had tried to repeat multiple table rows
- Embperl compiles now with perl5.005_57+. Patch from Ask Bjoern Hansen
- Cleanup now logs any errors that occurs when calling object
destructors and makes sure errors inside object destructors do
not break Embperl itself.
- Embperl now returns DECLINED when called for a directory. This
way Apache can handle diretories the correct way. This will make
DiretoryIndex (e.g. index.html) work again with Embperl.
- Fixed a problem that @ffld contains the same field more then
one time if posted from a select multiple with multiple items
selected. This caused problems with [$hidden$]. Spotted by
Martin Leja.
- Double quotes (") will be url-encoded to %22 inside URLs.
- Embperl now never writes to the logfile if EMBPERL_DEBUG is zero
- make test now runs with newest version of mod_ssl (2.3.5)
- Added option optKeepSpaces which will disable the removing of spaces
and empty lines from the output. Suggested from Gary Shea.
- Added option optOpenLogEarly, which will cause Embperl to open the
logfile as soon as it is loaded into memory. You can use this when
you loaded Embperl via PerlModule under Apache, to open the log
as root instead of the non-privileged user Apache runs as.1.2b4 (BETA) 15 Feb 1999
- fixed a problem that $req_rec was sometimes invalid on the
second call to the same page causing Embperl to SIGSEGV.
With help of Todd Eigenshink.
- Cleanup the variable space inside Embperl pages. Before this
fix many of the internal my variables were visible to the
Embperl page. Spotted by Todd Eigenshink.
- multiple form values with the same name are handled now
correctly (concated in a tab delimited string) when send
in a multipart/form-data (file-upload). Spotted by Dirk
Lutzebaeck.
- The dbgForm flag works now also for multipart/form-data
- a missing right *] will be reported as an error.
- [[* is correctly output as [* and not interpreted as a
starting of a perl block. Spotted by Dirk Lutzebaeck.
- fixed a bug that causes the html after an endforeach to be
skiped, when the foreach loop gets an empty array as argument.
Spotted by Dirk Lutzebaeck.
- Makefile.PL checks now for required modules and versions and
generates warnings if necessary
- Do not CLEAR %udat and %mdat in cleanup, so Apache::Session
will not warn anymore about unsupported CLEAR operation.
- Added tests for session management (%udat, %mdat)
- Added more tests to see that $req_rec is correctly setup
- Added module Apache::Session::epDBI which is a subclass of
Apache::Session::DBI and corrects a problem with locking and
cares of serializing requests, so %mdat works correctly.
Please read IMPORTANT NOTE under Session Management in
Embperl.pod
- Added the dbgProfile flag which cause the display of the time
since the request start for every source line in the logfile.
- Correct a problem that the escape character ('\') was not removed
when unescaping the input. Now '<' is correctly translated
to '<' and '\<' is translated to '<' .
- When requesting to view the logfile via the browser now all
lines which does not start with a pid ([<pid>]) are displayed.
- fixed a problem, that sometimes not all errors are shown in the
error page, in conjunction with dynamic tables
- When running under perl 5.005 or higher, the cleanup after the
every request, now not only cleans up scalars, array and hashs,
but also closes all open file- and directoryhandles and undef's
all typglob (which causes for example DBIx::Recordset objects to
DESTROY correctly)
NOTE: This also causes imported variables from other packages/modules
not to be cleanedup anymore!!
NOTE: That the cleanup behaveiour under perl 5.004 and 5.005 is
slightly differnt! The new cleanup doesn't work with 5.004 because
of a bug, which should be corrected in 5.004_05 as soon as available.
- EMail adress from the form is insert as Reply-To header instead of
From header in MailFormTo to avoid problems with unresolvable
EMail adresses.
- Fixed the problem that session management (%udat, %mdat) didn't
work when Execute is used in the same page. Spotted by by Simon Lindgren.
- Fixed a path problem in Makefile.PL. Now pathes on Win32 Systems uses
blackslash instead of slash. Spotted by Randy Kobes.
- Win32 batch files will no longer contain path to perl after the #!,
so cgi tests passes on systems with 4DOS shell. Spotted by Randy Kobes.
- Added ; as terminator for cookie to correctly parse multiple cookies.
Patch from Tim Carrol.
- Changed table_set to table_add when setting the cookie for session data
to avoid problems with other modules setting also cookies.
- Corrected the %ENV problem that mod_perl-1.18 introduced, so both
work together again.
- Added dbgSession flag to enable/disable logging of session handling
- Added configuration diretives EMBPERL_COOKIE_NAME, EMBPERL_COOKIE_DOMAIN,
EMBPERL_COOKIE_PATH and EMBPERL_COOKIE_EXPIRES to configure the cookie
which holds the session id. Suggested by Cliff Rayman.1.2b3 (BETA) 22 Nov 1998
- fixed an undefined pointer which occurs when using precompiled
[* ... *] blocks. Spotted by Bruce W. Holyman and Paul J. Schinder
- removed unwanted 0xa0 characters from tagscan.htm which causes
the test to fail on sunos. Spotted by Paul J. Schnider.
- Enhanced the detection of Stronghold, Apache SSL and mod_ssl
so they are found if they are not in a standard path. Spotted
by Brad Cox.
- Convert relativ path for apache source to absolute to avoid
problems within test script. Spotted by Brad Cox.
- Make Embperl compile with useperio=defined. Spotted by Todd
Eigenshink.
- Makefile.PL does now check if mod_perl is compiled into apache
and don't create a config for USE_DSO situtation even if
libperl.so exists.
- Added a workarround in the Execute('foo.htm') call, to avoid a
bug in perl5.004 which causes a SIGSEGV. Spotted by Michael J.
Schout and Chris Alexander.1.2b2 (BETA) 9 Nov 1998
- There is now a short form of the Execute function. You can
now include a sub page in an Embperl page by simply writing
[- Execute ('filename.html') -] or use
[- Execute ('filename.html', 1, 2, 3) -] to pass additional
parameters
- Added new block [* ... *]. This block compiles code to an
outer subroutine which surounds the whole page. This makes
it possible to define "local" variables with a scope of the
whole page, which would be necessary for recursive calls
to Execute.
Also this let you use perl control structures inside Embperl
pages: e.g.
[* foreach $v (1..5) { *] Cnt = [+ $v +] [* } *]
NOTE: [* ... *] blocks _must_ always end with a ;,{ or }
[* ... *] cannot apear inside html tags that are
interpreted by Embperl (unless you disable the
interpretation of such tags like table, input etc.)
- Added a comment block: Everything between [# and #] is a
comment and is removed from the output.
NOTE: [* ... *] blocks also interpreted inside of a
[# ... #] block, all other blocks [+/-/$ $/-/+] are not.
- Added magic hash %mdat, which can be used to store persitent
data on a per module basis (needs Apache::Session, with
path in session.patch applied)
- Done more tests on session handling, seems to work fine now.
- Added new option dbgNoHiddenEmptyValue which suppresses
empty hidden input fields in the [$hidden$] meta command.
Patch from Steve Willer.
- Whitespaces after [...] blocks are removed in the output, so
there will be less empty lines, makeing the output shorter and
more readable, based on a patch from Todd Eigenshink.
- Embperl compiles now with mod_ssl (from Ralf Engelschall).
Spotted by Dirk Lutzebaeck and Randel Schwartz.
- Added a patch from Todd Eigenshink to build Embperl with
Stronghold 2.4.1
- Added patch from Gerald McLarnon so Embperl compiles on AIX
- Added optAllowZeroFileSize to accept files of length 0,
without that option Embperl will report NOT_FOUND.
Suggested by Doug Bagley
- fixed a wrong call to logerror when OPT_EXECCGI is not on,
spotted by Dirk Lutzebaeck.
- fixed the problem that reloads only takes place at the next day,
because mtime was an int instead of a double (introduced in1.2b1.
Spotted by Michael Smith and Roman Maeder.
- fixed a problem that changing of the filesize was ignored, when
a documents is reloaded (introducted in 1.2b1)
- cleanup for all subpages are disabled if main request has
disabled cleanup and subpages does not specify otherwise
- dbgShowCleanup works again
- Every package is only cleanuped once, also it's included multiple
times in one page
- %fdat and @ffld are setup correctly when optDisableVarCleanup
is set
- DEFS=-DEPDEBUGALL compiles again, spotted by Michael Smith
- fixed that cleanup is never called with Execute nesting, when
req_rec was not set. Now the parameter req_rec isn't necessary
anymore. Spotted by Michael J.Schout
- Changes of $escmode inside a HTML-A tag now handled correctly,
spotted by Michael Smith
- fixed problems with links to the logfile and the line break
in the html log file display
- fixed a problem with blocks that expand to nothing inside of Embperl
interpreted HTML tags.
- Adapted test script to modified error output of Apache 1.3.4.
Spotted by Eric Cholet.
- Empty values (VALUE="") in input tags will not be overridden by
value in %fdat1.2b1 (BETA) 8 Oct 1998
- I have reworked the whole source code so Embperl is now
going to be an object. This means Embperl is reentrant, you
can call Execute within an Embperl page, for example to include
the same header on each page.
- Addeded Session handling via Apache::Session. Simply store data
to %udat and let Embperl do the rest for you. Experimental!
NOTE: You need Apache-Session-0.16.1 or higher and must apply
the patch from session.patch to it.
- Added test for calling Execute inside a Embperl page
- Errors of Input/Output function now also log to the httpd error log
- Added an test for input file not found1.1.1 15 Sep 1998
- A lot of documentation updates. Now Embperl ships with most of
the documentation which is also available on
http://perl.apache.org/embperl/
This includes:
- Intro.pod an introduction to Embperl
- Faq.pod an new very much extented version of the FAQ
and a lot of spell checking, gramar checking and so on
Thanks very much to Nora Mikes for putting together the FAQ
and doing a lot of proof reading.
- eg/x/upload.htm an example for file upload within Embperl
- splited documentation out of Embperl.pm into Embperl.pod
to make it load a little bit faster (Embperl.pm is now 30K
instead of 90K)
- Optimized the loading of other modules. Other modules are now
only loaded when really necessary. This make Embperl in CGI mode
about 2 times faster then version 1.1.0 was.
- Added a test for file-upload
- Embperl compiles and works now with threaded perl, but Embperl
is currently B<not> threadsafe. So you can use Embperl in a
threaded environement, but you have to make sure that only one
thread useses Embperl at a time.
- Fixed a memory leak which has occured in checkboxes and selects
- Enhanced test.pl
- MailFormTo: Send \n after mail header to work correctly with all
mail servers, added EMBPERL_MAILHOST to specify mail server hostname,
MailFormTo dies when it can't connect to mailserver. Spotted by
Steffen Geschke.1.1.0 28 Jul 98
- Added support for perl5.005 (currently only without threads!)
- Nesting of metacommands and HTML tags are now independent of
each other.
- Added examples in eg/x for do .. until, foreach, if,
DBI datbase access, DBIx::Recordset database access and a
input- / confirmation form.
- Added optUndefToEmptyValue which will cause Embperl to treat non-
existent values in %fdat as an empty string in input tags, as suggested
by Steve Willer.
- Catch "die" within EMBPERL_INPUT/OUTPUT_FUNC and write error
message to the logfile
- Write error message of LWP::UserAgent in ProxyInput to logfile
if any
- Added test for POST Requests
- Added support for tests when mod_perl is built with USE_DSO.
Spotted by Christian Oyarzun.
- Selects and checkboxes are setup correctly if state is set via %fdat.
Spotted by Todd Eigenschink and Steve Willer.
- Changes URL escaping so that only space, '+', '&', '=' and chars < 0x20
will be escaped to avoid problems with older netscape browsers.
- Added missing documentation for req_rec parameter of the Execute
function. Spotted by Eric Cholet.
- Send correct http header for error page, spotted by Steve Willer
- Fixed a memory leak in foreach metacommand
- Removed limit of 2048 Bytes for GET request data (there is no
limit anymore). Spotted by Steve Willer
- Read all POSTed data (not just the first 1024 Bytes). Patch from
Steve Willer.
- Removed some compiler warnings spotted by Tarang Kumar Patel
- Make sure all data is flushed to the logfile at the end of
each request
- Fixed a bug that causes Init to set DebugFlags to 1 instead of 0.
Spotted by Eric Cholet.1.1b2 27 Jun 98
- Added an additional note for input- and output- escaping
which is described in "Inside Embperl" section.
It's very important to understand this if you have any
problems with HTML tags or filehandles in your Perl code.
- Embperl will recognize Apache::exit. If called inside an
Embperl page or in a module called from an Embperl page,
the processing of the document is immediately aborted.
Everything processed so far is output/sent to the browser.
Based on a patch from Steve Willer.
- When running under mod_perl, 'exit' is an alias for Apache::exit
in every document.
- Enhanced the format of the Errorpage. Thanks for the patch
from Steve Willer
- Added a [$ foreach $] and a [$ do $] ... [$ until $]
metacommand
- Now multiple checkboxes with the same name will be set
correctly, to the values posted to the document. Spotted
by Todd Eigenshink and Nathan Krislock.
- [+ local $escmode = 0 .... +] works now. The first setting
of $escmode in a [+ ... +] block will now applied to the
whole block. You cannot change $escmode inside a [+ ... +]
block. Spotted by Chris Thormann.
- Fixed the return path setting in MailFormFields
- ProxyInput now passes http headers, so authentification
will be passed thru.
- Removed the limit 2048 for the length of HTML tags when [+ ... +]
are included. Now there is no limit anymore. Spotted by Doug Bagley1.1b1 14 Jun 98
- Now you can set custom input and/or output functions via
EMBPERL_INPUT_FUNC and EMBPERL_OUTPUT_FUNC. This can be
used to chain modules together or to get the input from
(or put the output to) non-standard locations.
- Added a function ProxyInput which can be used to fetch
the input from another URL instead of the disk. One possible
usage for this is to let mod_include parse the document first
and then let Embperl process it. Suggested by Steffen Geschke.
- Added a function LogOutput, which will write every generated
document to a unique file in addition to sending it to the
browser. Suggested by Dan Peterson.
- EMBPERL_FILESMATCH allows you to select which files in
a Location should be processed by Embperl. The rest are handled
by the Apache default handler. This allows you to have
Embperl and non-Embperl documents (like gifs etc.) in
the same directory.
- Logfile was displayed at the wrong position when requested via the
browser the first time after the httpd was started.1.0.0 12 Jun 98
- Make test runs with Apache 1.3.0, spotted by Eric Cholet
- Added a definition for MAX_PATH, which is not there on SunOS 4.1.4.
Spotted by Dan Peterson
- Fixed a bug that causes Makefile.PL to interpret MakeMaker parameters
spotted by Jason Bodnar
- Fixed a bug that caused EMBPERL_PACKAGE not to be recognized.
- Fixed a bug that caused optDisableFormData not to be recognized for
multipart formdata.0.28-beta 19 May 1998
- I have added a chapter "Inside Embperl" to the docs, I hope this
will make it clearer how escaping and unescaping works and how you
can get desired results. Highly recommended! (Thanks for spell- and
grammar-checking to Todd Eigenshink)
- make test now runs under win32 (You need to install LWP and libwin32)
IMPORTANT: You need a mod_perl version > 1.11 or you get a deadlock.
- Compiles with apache_1.3b6
- Added support for Stronghold and Apache_SSL to Makefile.PL and test.pl
- Changed dbgEarlyHttpHeader to optEarlyHttpHeader because it's not a
debugging option. dbgEarlyHttpHeader still persists, but will be removed
in one of the following versions
- Embperl does not change the current working directory when optDisableChdir
is set, this saves some milliseconds per request, also the cwd is moved
to the c code, so it runs faster then Cwd::fastwd.
Thanks to Doug Bagley for the profile which has shown how much time
Cwd::fastcwd consumes
- You can set optDisableHtmlScan in EMBPERL_OPTIONS. If set, Embperl only
recongizes [+/-/$/! ... !/$/-/+], but will not do anything with HTML tags,
as suggested by Randy Harmon.
- optDisableInputScan, optDisableTableScan and optDisableMetaScan can be
used to disable only some of the HTML tag processing
- You can set optDisableFormData in EMBPERL_OPTIONS. If set, Embperl
will not setup the %fdat and @ffld, as suggested by Doug Bagley
- If you use Execute, the explicit call to Init/Term isn't needed anymore,
because Embperl performs the Init automatically when it is loaded. The
Init function can still be used to change the path of logfile. Suggested
by Honza Jirousek
- All options and debugging flags can now be read/set at runtime. For
example $optRawInput = 1 sets the optRawInputFlag. Some of the options
are read-only, because they must be known before the request.
- Added more tests
- Embperl discards all errors which occur in an expression after the end
of a dynamic table, and which are only evaluated to detect the table end and
never displayed. This allows usage of object methods in dynamic tables,
where the table end is caused by an undefined object. (see
test/html/object.htm for an example). Spotted by Jason Bodnar.
- Printing to filehandle OUT has the same effect as using [+ .. +]
(including html-escaping)
- Setting optRedirectStdout causes Embperl to tie STDOUT to the Embperl
output stream (same as print OUT ...), suggested by Jason Bodar
- Setting optAllFormData will make empty formfields occur in %fdat and @ffld
with an empty string value, suggested by Dan Peterson
- Embperl now handles SELECT MULTIPLE correct. All OPTIONs which are
posted to the document will now be selected by Embperl, spotted by
Todd Eigenschink
- Fixed a bug that caused a '>' inside a [$/! ... !/$] block to be
interpreted as the end of a HTML tag, spotted by Todd Eigenschink.
- Fixed a bug which caused the SELECT/OPTIONS tag to not insert their
values in %idat and therefore made [$hidden$] work incorrectly, spotted by
Dave Paris [aka Spider]
- Fixed a bug that caused the INPUT CHECKBOX tag to not insert its
value in %idat when the value wasn't in %fdat and therefore made [$hidden$]
work incorrectly.
- Fixed a problem that caused magical variables to be handled as if they
were undefined, which caused dynamic tables to end, sometimes prematurely.
- Closing HTML tags will be correctly removed form Perl source again
(when optRawInput is not set)
- will be translated to space (0x20) instead of 0xf0
- When EMBPERL_DEBUG is set 0, only errors and warnings will be written to
the logfile
- MailFormTo will generate the correct TO header and insert a Return-Path
from the posted e-mail address
- Changed detection of mod_perl to $ENV{MOD_PERL}. This makes sure that
it will work correctly, even if Apache.pm isn't loaded.
- Re-entered the optDisableEmbperlErrorPage, which was lost in one of the last
releases, spotted by Doug Bagley.
- The content_length of the Apache request_rec will only be set when a http
header is sent.
- If, Elsif and While metacommands now use SvTRUE instead of a != 0 to test the
evaluated expression, so they now behave like the Perl ones do. Spotted by Jason
Bondar0.27-beta not available
0.26-beta 16 Mar 98
- Adapt include pass to compile with apache_1.3b5
- Applied patch from Dan Walters to make Embperl compile with
apache_1.3b3 and mod_perl on Win 32
- Changed the order of included c headers and undef some macros
inbetween (copied from mod_perl.c) to compile with Apache on Win 32
- Embperl works with apache_1.3b5 on Win NT ('make test' does not yet)
(You need the Apache source and must compile Perl with the vc++)
- Added the 'param' parameter to the 'Execute' function to pass parameters
from and to the Embperl document.
- Added the 'fdat' and 'ffld' parameter to the 'Execute' function to
setup %fdat and @ffld
- Fixed a problem which displayed tables a second time after the end of
the document, if dbgEarly HttpHeaders was on, thanks to Ask Bjorn Hansen
for spotting this.
- Fixed the return values of CheckFile, which was not correct after a change
from 0.24 to 0.25. Thanks to Todd Eigenschrink for spotting this.
- Fixed an error which was causing Embperl to crash on an HTML input tag without
the 'type' parameter. Thanks to Todd Eigenschrink for the hint.
- Fixed a problem that caused Embperl to not recognize errors correctly
when reading the sourcefile
0.25-beta 17 Feb 1998
- Included the "translation" of the Embperl POD to a human-readable
form done by Todd Eigenschink
- Started a FAQ file from the questions I answered by e-mail
- Added the function Execute, which can be called from Perl programs
(or Apache::Registry scripts), and can take input from (and/or
output to) memory, as suggested by Doug Bagley and Randy Harmon
(Look at test/html/registry/Execute.htm for an example)
- Changed the source so that it will compile on aix, spotted by
Patrick McAuliffe
- Access sys_errlist via perl macro Strerror to avoid errors with
redeclaration, thanks for spotting this to Honza Jirousek
- Changed the tab size from 4 to 8 in my editor to be compatible with
Unix standard
- Added warning if dbgLogLink is set and EMBPERL_VIRTLOG is not
- Changed the delimiter of metacommand from space to any non-alpha char
to allow writing [$while(a==b)$] as suggested by Michael D. Dowling
- Added config variable EMBPERL_ESCMODE to set inital values of $escmode
as suggested by Todd Eigenschink
- Added [! ... !]. Does just the same as [- ... -] but will only execute
on the first request for that document. This can be used to do one-time
initialization and to define subroutines.
- Changed push_handlers to register_cleanup, so PERL_STACKED_HANDLERS and
PERL_CLEANUP aren't necessary anymore, as suggested by Doug MacEachern
- If it exists, the function CLEANUP of the processed document will be called
before the variable cleanup, but after the connection to the client is closed
- Added a closing </font> in the logfile which is sent to the browser, otherwise
MS IE 4 can't handle it
- Changed Perl constants in Perl part from subroutines to "real" constants
- Did some general rearranging of code
- Fixed a memory leak which caused Embperl to lose one sv per Perl
block when a document is reloaded
- Fixed a bug which caused [+... +] within the Textarea tag to be ignored,
spotted by Todd Eigenschink
- Fixed a bug in sorting hidden fields
- Fixed a wrong argument to MakeMaker, which was causing Embperl to not be able
to build statically, spotted by Anatoli Belomestnov (and added a
description to the Faq on how to build a copy of Embperl which is statically-
linked to mod_perl)
- Fixed a problem which was causing the LOG filehandle to not be imported in
the documents package, this was causing everything printed to LOG to sort
of disappear 0.24-beta 13 Jan 1998
- Added the option optRawInput which causes Embperl not to pre-process the
source for a Perl expression (the only exception is that CR will be removed).
This option should be set when you are writing your code with an ascii editor.
If you are using a WYSIWYG editor, which inserts unwanted HTML tags in your
Perl expressions and escapes special characters automatically (i.e.
< will occur as < in the source), you should not set this option, and
Embperl will automatically convert the HTML input back to the Perl
expression you have written. (Thanks to Todd R. Eigenschink for a patch)
- $0 is set to the filename of the HTML source
- Change Current Working Directory to directory of HTML source
- Warning messages are now also logged in logfile at the correct
position, next to the source line
- Perl error and warning messages contain the filename and correct
linenumber of the HTML source
- Sourcelines in logfile contain linenumbers
- Output via [+ ... +] of undefined values at the end of a dynamic table
(which must be there to end the table) do not generate a warning anymore
NOTE: If you use them in an expression (such as $a = $arr[$row] or simply
inside " ", you will still get a warning)
- Open HTML source in binary mode on Win32 to avoid overhead of crlf -> lf
translation.
- Use aplog_error for apache_1.3 to avoid senseless os errors written to
httpd error log
- Removed some uninitializied value messages when running with
-w / PerlWarn on, spotted by Todd R. Eigenschink
- Fixed a bug which has caused nested 'while' loops to execute incorrectly
if the condition of the outer one is false 0.23-beta 31 Dec 1997
- Fixed a bug which caused $req_rec to be not defined anymore (Thanks to
Todd R. Eigenschink for the hint and debugging)
- Fixed a bug in escaping special HTML char to normal ascii (Thanks to
Todd R. Eigenschink for the hint)
- Makefile.PL now sets the path to your Perl binary in embpexec.pl and
embpexec.test.pl, so that it works regardless of where your Perl is located
(Thanks to Randall Schwartz for the hint)
- Added the SSLDisable to the test config when running an httpsd. (Thanks
to David Scott for the hint and Ralf S. Engelschall for the Syntax)
- Fixed a bug in <META> tag interpretation which was causing random errors
when not compiled for mod_perl0.22-beta 28 Dec 1997
- Changed include path generated in Makefile.PL so Embperl also
compiles with apache_1.3b3 (Thanks to Doug Bagley for the hint) 0.21-beta 25 Dec 1997
- Embperl offline mode now works under Win 32 (mod_perl and cgi mode
not tested under Win 32 yet, but maybe it works too)
- Totally reworked safenamespace and operatormask handling. Works now
without memory leak, is fully configurable and also does p-code
caching. If you use it, please look at the documentation, because
the configuration has changed.
- Embperl now sends its own error document if it detects an error.
The page contains all the error messages and if you have the
dbgLogLink enabled, all errors are links to the corresponding
line in the logfile. (this can be disabled with optDisableEmbperlErrorPage)
- Added new metacommand [$VAR ... $], which can be used to declare
variables and apply the strict pragma (same as use strict ; use vars )
- Added debug flag dbgHeadersIn which causes Embperl to log all http
headers which are received from the client
- Don't change any unknown HTML Escapes (i.e. && has been translated
to ? in versions < 0.21)
- dbgShowCleanup logs all variables which are automatically undefined at the
end of a request (for scalars the value is also shown)
- Error messages will also be cached, so that the compiling of the code
only takes place once, because erroneous Perl code will cause memory
leaks in Perl itself if it's compiled on and on and on.
- Optimized the compiling of the embedded Perl code
- Changed use Apache::Constants to conform with the new default exports
introduced in mod_perl-1.07_01
- Output of the 'hidden' metacommand is sorted in the same order as the input
from the formfields (sorting order can also be supplied as third argument)
- <meta http-equiv= ... > will override the corresponding http header
(this keeps netscape from asking the user to reload the document
when the content-type differs between the http header and the
meta http-equiv)
This can also be used to set http headers
- Fixed a problem that Embperl magic variables do not work when
the package exists before the first call to Embperl
- Fixed a problem that caused a SIGSEGV when retrieving the same document
containing a Perl error for the second time from the same child
- Fixed a problem that caused Embperl to terminate in offline/cgi-mode
when the file was not found or when access was forbidden
- Fixed a problem with the 'hidden' metacommand, which came up when
arguments were supplied with surrounding spaces
- Fixed a problem that Embperl did not handle metacommands correctly
when HTML tags (e.g. <br>) were embedded
0.20-beta 15 Nov 97
- Every file is executed in a separate package (don't confuse this
with safe namespaces) to reduce unwanted effects on each other
- Added the configuration directive EMBPERL_PACKAGE which can be used to override
the automatically-generated package name
- The namespace (package) used by a request is cleaned up afterwards.
That means that every scalar, hash or array is undef'ed after the
request to make sure nothing is lying around to possibly make the next request
misbehave.
This requires mod_perl with PERL_CLEANUP=1 and PERL_STACKED_HANDLER=1!
NOTE: To get persistent variables, place them in another namespace i.e.
write $persistent::x instead of $x
- Added configuration directive EMBPERL_OPTIONS to configure various runtime
options. Now only the scalar cleanup can be disabled.
- use log_error for writing to Apache error log to get timestamp
- Escaping inside an <A> tag is changed from an HTML escape to a URL escape
i.e. the space is translated to + and & is translated to %26 and so on
- Escaping can now be turned on and off via $escmode
- Concats ENV and cgi_env under mod_perl so that PerlSetEnv can be used
instead of SetEnv for configuration. In contrast to SetEnv, PerlSetEnv
allows different values per directory/virtual host
- Added two links to show source-loglines and eval-loglines when dbgLogLink
is enabled to have a quick jump to the logfile
- Reget pid for every request, so the correct one will be written to the
logfile, also when Embperl is loaded at server startup
- Check error log in make test, added test for error output
- Fixed a bug which causes Embperl to cause a SIGSEGV when a Perl syntax
error occurred
- Fixed a bug so that a '>' inside of [+/- ... -/+] is not detected as the end
of an HTML tag (Thanks to Todd R. Eigenschink)0.19-beta 29 Oct 97
- Rewrote the code for the LOG handle. Now the handle LOG is tied so that every
print/printf is written to embperl.log at the right position. Use this to
do logging from your embedded code or modules
- Fixed a bug which caused garbage to be displayed in dynamic tables (or made
parts of the table disappear) 0.18-beta 25 Oct 97
- Added caching of p-code. Now all Perl code is compiled only once. On the
second request, the compiled p-code is used. This makes, for example, the
table.htm from the test about 4 times faster on the second run then it was in
previous versions of Embperl. Also, tables and loops are faster in the first
request, because the code is only compiled in the first iteration.
- <Select>/<option> is now handled like <input>, this means that if a value
for the select exists in %fdat, the corresponding option is automatically
selected.
- Added support for table heading (<th> tag). If all cells in a row are surrounded
by <th>/</th> instead of <td>/</td> the row is interpreted as column headings and
printed only once. Row headings are not supported yet, but in one of the next versions...
- Added support for multipart/formdata to support fileupload. Embperl automatically
detects multipart/formdata and lets CGI.pm handle it. The results are also
present in @ffld and %fdat like for normal formdata. See CGI.pm for more docs.
(Thanks to eigenstr@mixi.net for the idea and material)
- Now all the output is kept in memory and the http-header are sent when the
processing is finish. This gives the ability to set http-headers (only under mod_perl)
within the page. Also now the Content-Length can be sent in the http-header.
(Thanks to eigenstr@mixi.net for the idea and material)
- Added tests for mod_perl mode and running as cgi-script, if compilation
for mod_perl is enabled (Thanks to Doug MacEachern for lots of ideas
and code I have borrowed from his mod_perl)
- Removed "= true" in MailFormTo which caused a warning and didn't declare
syserr_list in ep.h on FreeBSD (Thanks to Michael Fuhr for the hints)
- Added SYSNOPSIS section to docs to avoid pod2man warning and changed
apache/src/regx to apache/src/regex in Makefile.PL (Thanks to Bob Wilkinson)
- Splitted C-sources in some more source files
- Fixed two minor memory leaks. Now the Embperl test suite can run 1000 times and
more without making the httpd grow!0.17-beta 30 Aug 97
- Removed some Compiler Warnings (Thanks to Ian Kallen for reporting them)0.16-beta 29 Aug 97
- Added more restrictive access check when running under mod_perl
* Option ExecCGI must be set
* must not be a directory
- Added a (few) more docs about how to view the Embperl logfile with
your browser
- Added a declaration for error-dependent stuff to compile on Solaris, check errno before
accessing sys_errlist to avoid SIGSEVs, Fixed another warning from Sun Pro C Compiler
(Thanks to Dan Peterson)
- Switched I/O to PerlIO if supported by installed Perl version.
Should now work with sfio (not tested yet)
- Added possibilty to include Embperl commands in all HTML tags
(did not work for body, table and tr tags in previous versions)
- Will now preserve case of HTML tags
- Do not interpret unknown HTML tags in any way, so as to handle "<" characters
which do not start a HTML tag better
- Do not display the time needed for the request if CLOCKS_PER_SEC not
defined (e.g. SunOS - Thanks to Dan Peterson)
- Added apache_xx/src/regx to include path, to avoid problems when
Apache was built with its own regx library
- Now Embperl shows which tags don't match in error message (table, dir, select etc.)
- Fixed a bug which caused "[" characters to be printed even in a false
if path 0.15-beta 11 July 1997
- Added interpretation of SELECT Tag to generate dynamic listboxes
from an arrary
- Fixed a problem with dynamic lists
- Fixed some warnings displayed by the Sun Pro C Compiler (Thanks to Dan Peterson)
- Fixed an error message about missing IO::Handle
- Changed all // comments to /* */ to be more compatible with compilers other
than the gnu-c compiler
- Inserted a missing return in oputc which caused a SIGSEV on Solaris (Thanks
to Dan Peterson)
- Checked return code of Logfile open, to prevent a SIGSEV when Embperl cannot
write to the logfile (it now writes an error message in server's errorlog)
(Thanks to Dan Peterson)
- Errors will also be logged to the server's error log (written to stderr)
0.14-beta 30 Juni 1997
- adding 8192 to EMBPERL_DEBUG and setting EMBPERL_VIRTLOG will add a link
to Embperl output, so you can directly view the right part of the logfile
with your browser
- Added the LOG filehandle to print to the Embperl logfile
- Added the possibility to handle multiple form fields with same name
- chars which are a result of a Perl expression will not be escaped to HTML if
they are prefixed with a backslash
- Added support for scanning the parameters of input tags for Perl code i.e.
[- -] and [+ +] substitution takes place
- Replaced carriage return in Perl expression with space to avoid Perl 5.004 error
about carriage return
- added $req_rec to access the Apache server api when running under mod_perl
- Fixed a bug in Safe namespace handling which was always causing ERR: 17 Namespace unknown
- Fixed a bug which caused dynamic tables to end, if a 'if', 'while' and etc. was included
- Fixed a bug that caused [$cmd$] to be executed only in the first iteration of a 'while'
or a table
- Fixed some bugs in input tag interpretation
- Fixed a bug which occurred when Embperl encountered an input tag with value="" and %ffld=""
- Fixed a bug in embpexec.pl that caused the options to be ignored when running offline0.13-beta April 26 1997
- Moved EPENTRY (embperl_init) down to avoid crashing when compiled with
-DEPDEBUGALL
- Added #undefs for stdio function to compile with Perl > 5.003
NOTE: This is a quick hack, and will be changed to use PerlIO in
one of the next releases, so we can tie stdout of Embperl
- Added pids (to distinguish between muliplite requests) and time to
logfile output
- Made many functions static and names of externals more unique to
avoid conflicts of symbolnames with other modules
- If file not found return status 404 instead of 500
- Add Apache::Embperl so the module shows at CPAN also under
module/by-module/Apache/ as suggested by Doug MacEachern0.12-beta not publicly released
- The mask has been removed from namespace option so it can be used
with safe.pm > 2
- Embperl works with -T / PerlTaintCheck on
