[ANNOUNCE] mod_perl-2.0.4

Finally, it's here and it works with Perl 5.10!

http://apache.org/dist/perl/mod_perl-2.0.4.tar.gz
http://apache.org/dist/perl/mod_perl-2.0.4.tar.gz.asc (pgp sig)

The package is also available on CPAN:

file: $CPAN/authors/id/G/GO/GOZER/mod_perl-2.0.4.tar.gz
size: 3727717 bytes
md5: 1a05625ae6843085f985f5da8214502a
sha1: 65299a16ec414a690a48a2bbe63acaa3c6bb897b

Changes since 2.0.3:

Fix $r->location corruption under certain conditions
[Gozer]

Fix a crash when spawning Perl threads under Perl 5.10
[Gozer]

Fix erratic behaviour when filters were used with Perl 5.10
[Gozer]

Fix problems with redefinitions of perl_free as free and perl_malloc
as malloc on Win32, as described at
http://marc.info/?l=apache-modperl&m=119896407510526&w=2
[Tom Donovan]

Fix a crash when running a sub-request from within a filter where
mod_perl was not the content handler. [Gozer]

Refactor tests to use keepalives instead of same_interp [Gozer, Phred]

Apache2::Reload has been moved to an externally maintained
CPAN distribution [Fred Moyer <fred[at]redhotpenguin.com>]

PerlCleanupHandler are now registered with a subpool of $r->pool,
instead of $r->pool itself, ensuring they run _before_ any other
$r->pool cleanups [Torsten Foertsch]

Fix a bug that would prevent pnotes from being cleaned up properly
at the end of the request [Torsten Foertsch]

On Win32, embed the manifest file, if present, in mod_perl.so,
so as to work with VC 8 [Steve Hay, Randy Kobes]

Expose apr_thread_rwlock_t with the APR::ThreadRWLock module
[Torsten Foertsch]

Don't waste an extra interpreter anymore under threaded MPMs when using a
modperl handler [Torsten Foertsch]

Fix a bug that could cause a crash when using $r->push_handlers() multiple
times for a phase that has no configured handlers [Torsten Foertsch]

Catch up with some httpd API changes
2.2.4:
The full server version information is now included in the error log at
startup as well as server status reports, irrespective of the setting
of the ServerTokens directive. ap_get_server_version() is now
deprecated, and is replaced by ap_get_server_banner() and
ap_get_server_description(). [Jeff Trawick]

2.3.0:
ap_get_server_version() has been removed. Third-party modules must
now use ap_get_server_banner() or ap_get_server_description().
[Gozer]

fixed Apache2::compat Apache2::ServerUtil::server_root() resolution
issues [Joshua Hoblitt]

*) SECURITY: CVE-2007-1349 (cve.mitre.org)
fix unescaped variable interprolation in regular expression
[Randal L. Schwartz <merlyn[at]stonehenge.com>, Fred Moyer <fred[at]redhotpenguin.com>]

Make $r->the_request() writeable
[Fred Moyer <fred[at]redhotpenguin.com>]

fix ModPerl::RegistryCooker::read_script to handle all possible
errors, previously there was a case where Apache2::Const::OK was
returned on an error. [Eivind Eklund <eeklund[at]gmail.com>]

a minor compilation warning resolved in modperl_handler_new_from_sv
[Stas]

a minor compilation warning resolved in modperl_gtop_size_string
[Stas]

Prevent direct use of _deprecated_ Apache2::ReadConfig in
<Perl> sections with httpd Alias directives from
incorrectly generating
'The Alias directive in xxxxx at line y will probably never match'
messages.
[Philip M. Gollucci <pgollucci[at]p6m78g.com>]

Prevent Apache2::PerSections::symdump() from returning invalid
httpd.conf snippets like 'Alias undef'
[Philip M. Gollucci <pgollucci[at]p6m78g.com>]

Require B-Size 0.9 for Apache2::Status which fixes
Can't call method "script_name" on an undefined value
[Philip M. Gollucci <pgollucci[at]p6m78g.com>]

-march=pentium4 or anything with an = in it in CCFLAGS or @ARGV
that gets passed to xs/APR/APR/Makefile.PL broke the @ARGV
parsing. I.E. FreeBSD port builds when users had CPUTYPE
set in /etc/make.conf.
[Philip M. Gollucci <pgollucci[at]p6m7g8.com>]

Fixes to get bleed-ithread (5.9.5+) to comile again.
[Philip M. Gollucci <pgollucci[at]p6m7g8.com>]

I think we knew that (or am I getting mixed up with the mp1 RC?) and it

Get us a core dump if you can, ideally with debugging information.

http://perl.apache.org/docs/2.0/devel/debug/c.html#Analyzing_Dumped_Core_Files

In a nutshell, rebuild with

perl Makefile.PL MP_DEBUG=1 [...]

And proceed until you get a core dump.

Then use t/REPORT to submit a bug report, with the backtrace.

Mixed up with the mp1 RC I believe. This problems seems like news to me ;-(

I don't have a FreeBSD machine handy, so, Philip, is there any chance you
could try and figure out a little more about what's going on?

Something is tripping up the compiler, so maybe
apache/include/apr_thread_rwlock.h has something funky in there (or isn't
even there)

Any chance you could run that one compilation invocation with
gcc -E instead ? That way, we can see the source _after_ macro
expansion, and it might help a lot in figuring out what's going on.

My APR was compiled without Threads (/var/db/pkg/apr-nothr)

I'll look at tweaking the detection.

Sounds like a problem with APR without threads.

I think this patch to a bit of *magical* code should do the trick.

Index: lib/ModPerl/BuildMM.pm

Feels like something that doesn't belong in there, but rather in the
configuration somewhere in xs/maps...
