Beside some small fixes, this release adds support for Apache 2.2 and a dump
meta command which simplifies debugging.

Embperl is a system for building dynamic websites with Perl.
It gives you the power to embed Perl code in your HTML/XML documents and the
ability to build your Web site out of small reusable objects in an
object-oriented style.
Embperl has several features which are especially useful for creating
Websites, including dynamic tables, form field processing, URL
escaping/unescaping, session handling, caching, xslt transformation and
more.
See http://perl.apache.org/embperl/ (english) or http://www.ecos.de/embperl/
(german) for more information.
Enjoy
Gerald
Changes since 2.1.0:
- Added new command [$ dump $] which can be used
to dump variables to logfiles or to the output
for debugging purpose.
- [$ sub $] return value is handled now corretly
in scalar and array context
- Added support for Apache 2.2
- Added Table of Content pod file, which lists
all available Embperl documentation, to get
a better overview. Thanks to Axel Beckert.
- Fixed Cookie expire calculation, because
relative exipre times where only calculated
once at server startup. Spotted by Derrick Spell.
- Fixed parsing of Cache configuration functions in
httpd.conf. Spotted by Carl Eklof.
- Added better handling of Out Of Memory condition,
i.e. log error end try to clean up instead of
segfault.
- Fixed segfault that could occur because a non
string value is passed as string index, which
crashed if such a string index doesn't exists.
Spotted by Carl Eklof.

Yes, I've done it and not any explicit error message is shown. Here is
the last script test I've used and it crashes the same way.
I only get the "before fork ok" in browser and perl.exe crashes, nothing
more. The only more thing I know, debugging the crash using Visual
Studio is that the exception occurs in PERL58.DLL.
#!/usr/bin/perl -T
use strict;
use warnings;
use CGI::Carp qw/fatalsToBrowser/;
print "Content-type: text/html\n\n";
print "before fork ok<br>";
my $pid = fork();
die "fork: $!\n" unless defined $pid;
if (!$pid){
print "son ok<br>";
exit 0;}
print "daddy ok<br>";
exit 0;

That script runs fine with my IndigoPerl build of Perl (5.8.6).

Well, on my side, I'm using ActivePerl 5.8.7 build 815 and this script
works fine if not in taint mode only :-(

That is really a matter of terminology. With most computer languages
an identifier is something that starts with a non-digit. I prefer that
view for Perl too, while $3, @3, etc. are exceptional variables whose
names are *not* identifiers.
