=item 1.99_11 - November 10, 2003

add a build/win32_fetch_apxs script (called within the top-level
Makefile.PL) to offer to fetch and install a Win32 development
version of apxs and (apr|apu)-config [Randy Kobes]

rewrite $r->read() and perlio read functions to use the same function,
which completely satisfies the read request if possible, on the way
getting rid of get_client_block and its supporting functions which
have problems and will most likely will be removed from the httpd-API
in the future. Directly manipulate bucket brigades instead. [Stas]

Since Apache2.pm pops /foo/Apache2 dirs to the top of @INC, it now
also takes care of keeping lib and blib dirs before the system dirs,
so that previously installed libraries won't get loaded instead of the
currently uninstalled libraries that are under test. [Stas]

When 'make test' fails we now print the info on what to do next [Stas]

At the end of 'make install' we now print the info how to proceed with
mod_perl and what to do in the case of post-install problems [Geoff]

Adjust the source to properly work with 5.8.2's new algorithm of
dynamic re-hashing of hashes on hash collision attack. [Nicholas Clark
<nick@ccl4.org>, Stas]. Add a test that mounts such an attack so we
can verify that we can survive this rehashing. [Scott A Crosby
<scrosby@cs.rice.edu>, Nicholas Clark <nick@ccl4.org>, Tels
<perl_dummy@bloodgate.com>, Mark Jason Dominus <mjd@plover.com>, Stas]

Standardize the Apache::PerlSections package name to it's plural form for
clarity and so that the pod gets glued in it's proper place.
[Philippe M. Chiasson <gozer@cpan.org>]

return value from Perl callbacks are now passed directly to Apache
without additional post-call manipulations (such as assuming HTTP_OK
should really be OK).  [Geoffrey Young]

perl 5.8.1 w/ ithreads has a bug where it reports the wrong parent pid
(as if the process was never forked), provide a local workaround (+ new
test). [Rafael Garcia-Suarez <rgarciasuarez@free.fr>]

overriden STD* streams now can be further overriden and will be
properly restored, which allows functions like $r->internal_redirect
work (+add tests) [Stas]

implement perlio's getarg hook, which now allows dupping STD* streams
overloaded by modperl [Stas]

Add PerlMapToStorageHandler [Geoffrey Young]

callbacks are now expected to return a meaningful value 
(OK, SERVER_ERROR, etc) or return via an official API 
(exit, die, etc).  relying on implicit returns from the 
last call evaluated by a subroutine may result in server 
errors.  [Stas, Geoffrey Young]

in the MP_MAINTAINER mode add the -Werror compilation flag when perl
v5.6.2 or higher is used, so that we don't miss compilation
warnings. [Stas]

fix the Makefile.PL option parser to support overriding of certain
build options, in addition to appending to them (.e.g. now MP_LIBNAME
is overridable) [Andrew Wyllie <wyllie@dilex.net>]

make sure that connection filters won't be inserted as request filters
[Stas]

Prevent the 'Use of uninitialized value.' warning when
ModPerl::Util::exit is used. [Stas]

To make the test-sute sandbox-friendly, which break when things try to
run off /tmp, use t/logs as the location of the mod_cgid socket and
TMPDIR env var [Haroon Rafique <haroon.rafique@utoronto.ca>]

=item 1.99_10 - September 29, 2003

added Apache::CRLF, Apache::CR, and Apache::LF to
Apache::Const's :platform group  [Geoffrey Young]

make sure that the custom pools are destroyed only once and only when
all references went out of scope [Stas]

($r|$c)->add_(input|output)_filter(\&handler) now verify that the
filter of the right kind is passed and will refuse to add a request
filter as a connection filter and vice versa. The request filter
handler is not required to have the FilterRequestHandler attribute as
long as it doesn't have any other attributes. The connection filter
handler is required to have the FilterConnectionHandler
attribute. [Stas]

fix tracing with (PerlTrace/MOD_PERL_TRACE) on win32 (the error_log
filehandle was invalid after the open_logs phase) [Stas]

fix a bug where %ENV vars set via subprocess_env persist across
requests.  (e.g. a Cookie incoming header which ends up in
$ENV{HTTP_COOKIE} would persist to the next request which has no
Cookie header at all). Now we unset all the %ENV vars set from
subprocess_env. Improve and extend the tests to cover this bug. [Stas]

it is invalid to return HTTP_INTERNAL_SERVER_ERROR or any other HTTP
response code from modperl_wbucket_pass, therefore set the error code
into r->status and return APR_SUCCESS. Untill now response handler
with messed up response headers, were causing no response what so ever
to the client.  LWP was assuming 500, and it was all fine, testing
without LWP has immediately revealed that there was a problem in the
handling of this case. [Stas]

put the end to the 'Not a CODE reference' errors, instead provide an
intelligent error message, hopefully telling which function can't be
found.  at the same time improve the tracing to include the pid/tid of
the server that has encountered this problem, to make it easier to
debug. [Stas]

mod_perl handler must be dupped for any mpm which runs within
USE_ITHREAD.  Untill now there was a big problem with prefork mpm if
any of its vhosts was using PerlOptions +(Parent|Clone) and happened
to load handlers before the main server. When that was happening the
main server will see that the handler was resolved (since it sees the
handler struct from the vhost that loaded this module, instead of its
own), which in fact it wasn't, causing the failure to run the handler
with the infamous 'Not a CODE reference' error. [Stas]

Make sure that the static mod_perl library is built after the dynamic
(a requirement on win32) [Steve Hay <steve.hay@uk.radan.com>]

Apache::Status now generates HTML 4.01 Strict (and in many cases, also
ISO-HTML) compliant output. Also add a simple CSS to make the reports
look nicer. [Ville Skyttä <ville.skytta@iki.fi>]

APR::Pool::DESTROY implemented and tweaked to only
destroy pools created via APR::Pool->new() [Geoffrey Young]

$r->slurp_filename is now implemented in C. [Stas]

remove support for httpd 2.0.45/apr 0.9.3 and lower.
httpd 2.0.46 is now the minimum supported version.
[Geoffrey Young]

APR::PerlIO now accepts the pool object instead of a request/server
objects, so it can be used anywhere, including outside mod_perl [Stas]

when perl is built with perlio enabled (5.8+) the new PerlIO Apache
layer is used, so now one can push layers onto STDIN, STDOUT handles
e.g. binmode(STDOUT, ':utf8'); [Stas]

add ap_table_compress() to APR::Table [Geoffrey Young]

alter stacked handler interface so that mod_perl follows Apache 
as closely as possible with respect to VOID/RUN_FIRST/RUN_ALL
handler types.  now, for phases where OK ends the Apache
call list (RUN_FIRST handlers, such as the PerlTransHandler), 
mod_perl follows suit and leaves some handlers uncalled.
[Geoffrey Young]

Apache::Build now tries to use the new APR_BINDIR query string to find
the location of apr-config. [Stas]

new package Apache::porting to make it easier to port mp1 code to mp2
[Stas]

new Apache::Build methods: mpm_name(), mpm_is_threaded(). use them in
the top-level Makefile.PL to require 5.8.0/ithreads if mpm requires
threads. [Stas]

add the missing XS methods to ModPerl::MethodLookup, add support for
mp1 methods that are no longer in the mod_perl 2.0 API. [Stas]

mod_perl now refuses to build against threaded mpms (non-prefork)
unless perl 5.8+ w/ithreads is used [Stas]

don't try to read PERL_HASH_SEED env var, where apr_env_get is not
available (apr < 0.9.3) [Stas]

APR.so now can be loaded and used outside mod_perl (all the way back
to httpd 2.0.36) [Stas]

perl 5.8.1 randomizes the hash seed, because we precalculate the hash
values of mgv elements the hash seed has to be the same across all
perl interpreters. So mod_perl now intercepts cases where perl would
have randomize it, do the seed randomization by itself and tell perl
to use that value. [Stas]

fix APR::PerlIO layer to pop itself if open() has failed. [Stas]

move the definition of DEFINE='-DMP_HAVE_APR_LIBS' to the top level
Makefile.PL, since it overrides MY::pasthru target which makes it
impossible to define local DEFINE in subdirs. [Stas]

make APR perl functions work outside mod_perl: several libraries
weren't linked. Also LIBS needs to receive all libs in one
string. [Stas]

Apache::compat: $r->cgi_env, $r->cgi_var are now aliases to
$r->subprocess_env [Stas]

For Win32, generate .pdb files for debugging when built with
MP_DEBUG. These will get installed into the same directory as
the associated dll/so libs. As well, install mod_perl.lib
into MP_AP_PREFIX/lib/ for use by 3rd party modules [Randy Kobes].

Apache2.pm is now autogenerated and will adjust @INC to include
Apache2/ subdirs only if built with MP_INST_APACHE2=1 [Stas]

Change the default value for the argument 'readbytes' for
ap_get_brigade(), from 0 to 8192. other than being useless, 0 always
triggers an assert in httpd internal filters and 8192 is a good
default. [Stas]

Fix DynaLoader breakeage when using DL_GLOBAL on OpenBSD
[Philippe M. Chiasson <gozer@cpan.org>]

renamed the private modperl_module_config_get_obj function to 
modperl_module_config_create_obj, since the logic creates 
the object but doesn't dig it out if it already exists.  then,
moved logic from mpxs_Apache__Module_get_config into a new public
C function that reused the old name, modperl_module_config_get_obj.
while Apache::Module->get_config exists as a wrapper to return the
object to Perl space, now C/XS folks can also access the object
directly with the public function.
[Geoffrey Young]

Apache::Reload: add a new config variable:
ReloadConstantRedefineWarnings to optionally shut off the constant sub
redefine warnings [Stas]

implement $parms->info.  directive handlers should now be complete.
[Geoffrey Young]

MP_GTOP now works with modern GCC
[Philippe M. Chiasson <gozer@cpan.org]

add missing dependencies to Apache::PerlSections
[Geoffrey Young]

$r->get_client_block is bogus in httpd-2.0.45 (and ealier), as it
can't handle EOS buckets arriving in the same bucket brigade with
data. so rewrite ModPerl::Test::read_post to use an explicit read
through all bucket brigades till it sees eos and then it stops. The
code is longer but it works correctly. [Stas]

an attempt to resolve the binary compatibility problem in
PerlIOAPR_seek API when APR_HAS_LARGE_FILES=0 [Stas]

perl 5.8.0 forgets to export PerlIOBase_noop_fail, causing problems on
win32 and aix. reimplement this function locally to solve the
problem. APR::PerlIO should now be useful on win32 and aix [Stas]

implement DECLINE_CMD and DIR_MAGIC_TYPE constants
[Geoffrey Young]

allow init filter handlers to call other methods than just $f->ctx [Stas]

Fix Apache::Reload to gracefully handle the case with empty Touchfiles
[Dmitri Tikhonov <dmitri@netilla.com>]

PerlRequire entried should be executed before PerlModule entries in
VirtualHost containers, just like in the base server [Stas]

=item 1.99_09 - April 28, 2003

$filter->seen_eos() now accepts 1/0 to set/unset the flag so streaming
filters can control the sending of EOS. [Stas]

support systems where apr header files are installed separately from
httpd header files ["Andres Salomon" <dilinger@voxel.net>]

implement init filter handlers + tests [Stas]

improving ModPerl::MethodLookup to:
- handle more aliased perl XS functions
- sort the methods map struct so one can use the autogenerated map as is
- add lookup_module, tells which methods are defined by a given module
- add lookup_object, tells which methods can be called on a given object
- provide autoexported wrappers print_method, print_module and
  print_object for easy deployment from the command line
[Stas]

add Perl glue for functions: APR::Socket::timeout_get
APR::Socket::timeout_set [Stas]

similar to SetEnv, upcase the env keys for PassEnv on platforms with
caseless env (e.g. win32) [steve.sparling@ps.ge.com]

Add a backcompat wrapper for $r->notes (mp2 supports only the
APR::Table API) [Stas]

Add a script mp2bug and a target 'make bugreport', so people can use
bugreporting during the build and after modperl is installed. [Stas]

Add a script mp2doc as a replacement for perldoc (due to 2.0 modules
living under Apache2, which won't be looked at by perldoc). [Stas]

Add a constant APR::PerlIO::PERLIO_LAYERS_ARE_ENABLED and use it in
tests [Stas]

Require perl 5.8 or higher when building mod_perl on OSes requiring
ithreads (e.g., win32), since 5.6.x ithreads aren't good. [Stas]

MP_COMPAT_1X=0 now can be passed to Makefile.PL to disable
mp1-back-compat compile-time features + adjust tests. [Stas]

<SERVER_ROOT> and <SERVER_ROOT>/lib/perl are now added to @INC, just
like mod_perl 1.0 with MP_COMPAT_1X=1 (currently enabled by
default). [Stas]

The Perl-5.8.0 crypt() workaround is now used only if 5.8.0 is used,
since 5.8.1-tobe/5.9.0-tobe(blead-perl) won't compile with
it. [Geoffrey Young]

new directives PerlSetInputFilter and PerlSetOutputFilter, which are
the same as SetInputFilter and SetOutputFilter respectively, but allow
to insert non-mod_perl filters before, between or after mod_perl
filters. + tests [Stas]

improved filters debug tracing [Stas]

implement $filter->remove (filter self-removal) + tests [Stas]

remove the second-guessing code that was trying to guess the package
name to load from the handler configuration (by stripping ::string and
trying to load the package). fall back to using explicit PerlModule to
load modules whose handler sub name is not called 'handler' + adjust
tests. [Stas]

set the magic taint flags before modules are required [Stas]

make sure to set base server's mip before any of the
PerlRequire/PerlModule directives are called, since they may add
add_config(), which in turn runs Perl sections or PerlLoadModule,
which may need the scfg->mip to be set. [Stas]

ModPerl::MM is now ready to be used in Makefile.PL of 3rd party
mod_perl modules [Stas and Geoff]

fix a segfault caused by PerlModule in $s->add_config, due to setting
the MP_init_done flag before init was done + add test [Stas]

adjust the generated Makefile's to properly build on aix (tested on
powerpc-ibm-aix5.1.0.0) [Stas]

the build now automatically glues the .pod files to the respective .pm
files, so one can use perldoc on .pm files to read the
documentation. [Stas]

provide a workaround for ExtUtils::MakeMaker::mv_all_methods, so
ModPerl::BuildMM and ModPerl::MM can override EU::MM methods behind
the scenes. [Stas]

adding ModPerl::BuildMM, which is now used for building mod_perl.
ModPerl::MM will be used for 3rd party modules. ModPerl::BuildMM
reuses ModPerl::MM where possible. [Stas]

drop the glue code for apr_generate_random_bytes, since it's not
available on all platforms. [Stas]

Since non-threaded mpms don't use tipools in mips, don't create and
destroy them. [Stas]

re-use the workaround for glibc/Perl-5.8.0 crypt() bug for the
main/vhost base perl interpreters as well. This solves the problem for
the buggy glibc on RH8.0. [Stas]

send_cgi_header now turns the header parsing off and can send any data
attached after the response headers as a response body. [Stas]

move the check that print/printf/puts/write/etc are called in the
response phase into the functions themselves so 1) we can print a more
useful error message 2) this check is not always needed in
modperl_wbucket_write, when called internally, so we save some cycles.
[Stas]

add checks that print/printf/puts/write/etc are called in the response
phase. move the check into the functions themselves so we can print a
more useful error message [Stas]

'make install' now installs mod_perl*h files under httpd's include
tree [Stas]

When PerlOptions +ParseHeaders is an effect, the CGI headers parsing
won't be done if any *mod_perl* handler before and including the
response phase, sets $r->content_type.  (similar behavior to mp1's
send_http_header() [Stas]

Registry: make sure that $r is not in the scope when the script is
compiled [Stas]

$Apache::Server::SaveConfig added. When set to a true value,
will not clear the content of Apache::ReadConfig:: once <Perl >
sections are processed. [Philippe M. Chiasson <gozer@cpan.org]

Apache::compat: support 1.0's Apache->push_handlers,
Apache->set_handlers and Apache->get_handlers [Stas]

revamp the code handling output flushing and flush bucket
sending. Namelly modperl_wbucket_flush and modperl_wbucket_pass now
can be told to send a flush bucket by themselves, attaching it to the
data bb they are already sending. This halfs the number of output
filter invocations when the response handler flushes output via $| or
rflush. adjust tests, which were counting the number of invocations.
[Stas]

move ModPerl::RegistryCooker to use a hash as object (similar to mp1),
to make it easier to subclass. [Nathan Byrd <nathan@byrd.net>]

$r->rflush has to flush internal modperl buffer before calling
ap_rflush, so implement rflush, instead of autogenerating the xs code
for it. [Stas]

fix the input filters handling of DECLINED handlers (consume the data,
on behalf of the handler) + tests [Stas]

fix the code that autogenerates modperl_largefiles.h not to define
macros matching m/^-/ (was a problem on aix-4.3.3) [Stas]

$Apache::Server::StrictPerlSections added. When set to a true
value, will abort server startup if there are syntax errors
in <Perl > sections [Philippe M. Chiasson <gozer@cpan.org]

Use Win32::GetShortPathName for Win32 to handle cases when
the supplied MP_AP_PREFIX contains spaces. [Randy Kobes]

Bump up ThreadsPerChild for mpm_winnt in httpd.conf, which seems 
to help avoid server startup problems when running the tests.
[Randy Kobes]

implement a new helper module ModPerl::MethodLookup to help figure out
which module should be loaded when a certain method is reported to be
missing. [Stas]

fix a bug for apr < 0.9.3, where it segfaults in apr_uri_unparse, if
hostname is set, but not the scheme. In case the hostname is defined
but scheme is not Apache::compat will default to the 'http' scheme,
whereas APR::URI::unparse provides no default [Stas]

move $r->send_http_header implementation to Apache::compat.  This
allows the 1.0 code to run unmodified if $r->send_http_header is
called before the response change. we already handle the check whether
content_type was set, when deciding whether the headers are to be
parsed inside modperl_wbucket_pass(). [Stas]

fixes to Apache::compat. make $r->connection->auth_type interface
with r->ap_auth_type. make both $r->connection->auth_type and
$r->connection->user writable. [Geoffrey Young]

Open up r->ap_auth_type, making it possible to write custom
authen handlers that don't rely on Basic authentication or
it's associated ap_* functions.
[Geoffrey Young]

add Apache::Bundle2 [Stas]

Apache::Reload now supports the PerlPreConnectionHandler invocation
mode, so connection filter and protocol modules can be automatically
reloaded on change. [Stas]

implement Apache::current_callback + $r->current_callback goes into
Apache::compat, since now we have a way too many callbacks unrelated
to $r [Stas]

Add Apache::compat methods: $r->connection->auth_type and
$r->connection->user (requires 'PerlOptions +GlobalRequest') + tests
[Stas]

Several issues resolved with parsing headers, including making work
the handlers calling $r->content_type() and not sending raw headers,
when the headers scanning is turned on. Lots of tests added to
exercise different situations. [Stas]

warn on using -T in ModPerl::Registry scripts when mod_perl is not
running with -T [Stas]

perl 5.7.3+ has a built-in ${^TAINT} to test whether it's running
under -(T|t). Backport ${^TAINT} for mod_perl running under
5.6.0-5.7.3, (what used to be $Apache::__T.  $Apache::__T is available
too, but deprecated. [Stas]

add PerlChildExitHandler implementation [Stas]

add PerlCleanupHandler implementation + test [Stas]

die when Apache->request returns nothing ('PerlOptions -GlobalRequest'
or 'SetHandler modperl') [Stas]

New Apache::Directive methods: as_hash(), lookup() + tests + docs
[Philippe M. Chiasson <gozer@cpan.org>]

Stacked handlers chain execution is now aborted when a handler returns
something other than OK or DECLINED [Stas]

make $filter->read() in input streaming filters, use the same number
of arguments as read() in the output filters. [Stas]

Implement $r->add_input_filter and $r->add_output_filter
          $c->add_input_filter and $c->add_output_filter
and add tests  [Stas]

Skip the handler package::func resolving error, only when the error
message matches "Can't locate .*? in @INC", rather than just "Can't
locate", since there are many other errors that start with that
string. [Stas]

the top level 'make test' now descends into the ModPerl-Registry dir
to run 'make test' there [Stas]

All response functions are now returning status and the callers check
and croak on failure or progate them further. [Stas]

OPEN, CLOSE and FILENO implementation for Apache::RequestRec [Stas]

Another fix for the handling of the return status in
ModPerl::RegistryCooker: reset the status to the original one only if
it was changed by the script, otherwise return the execution status
[Stas]

prevent segfault in $r->print / $filter->print (in output filter) and
related functions when they are called before the response phase
[Stas]

prevent segfault in send_http_header when it's called before the
response phase [Stas]

input stream filtering support was added + tests (plus renaming filter
tests so we can know from the test name what kind of filter is tested)
[Stas]

Add proper support for mis-behaved feeding filters that send more than
one EOS bucket in streaming filters + test. [Stas]

prevent a segfault when push_handlers are used to push a handler into
the currently phase and switching the handler (perl-script/modperl) +
tests [Stas]

Add $filter->seen_eos to the streaming filter api to know when eos has
been seen, so special signatures can be passed and any data stored in
the context flushed + tests. [Stas]

Add $filter->ctx to maintain state between filter invocation + tests
[Stas]

Request input and output filters are now getting the EOS bucket, which
wasn't passed through before. Now the context can be flushed on
EOS. [Stas]

=item 1.99_08 - January 10, 2003

Correct ModPerl::RegistryCooker to reset %INC, after compile for .pl
files which don't declare the package + add tests to check that [Stas]

Log the real error message when Foo::Bar::sub_name fails to resolve,
because of a problem in Foo::Bar, when Foo::Bar *was* found [Stas]

Add PerlPreConnectionHandler support in Apache::Test [Stas]

Enable PerlPreConnectionHandler [Stas]

Support the Host: request header in Apache::TestClient [Stas]

restore the ModPerl::RegistryLoader::new() method for backwards
compatibility  [Stas]

port the support for NameWithVirtualHost in ModPerl::RegistryCooker
and ModPerl::RegistryLoader [Stas]

fix the handling of the return status in ModPerl::RegistryCooker, add
a test to verify that [Stas]

under non-threaded perl need to check whether mod_perl is running,
when modperl_vhost_is_running check is done. [Stas]

fix $r->read to read all the requested amount of data if possible,
adjust the test TestApache::read to verify that [Stas]

fix the method content() in Apache::compat to read a whole request
body. same for ModPerl::Test::read_post. add tests.  [Stas]

Adjust the reverse filter test to work on win32 (remove trailing \r)
[Randy Kobes <randy@theoryx5.uwinnipeg.ca>]

Strongly suggest win32 users to upgrade to 5.8.0, if they run 5.6.x
[Randy Kobes <randy@theoryx5.uwinnipeg.ca>]

When installing the mod_perl shared object, first need to check
whether the directory 'modules' already exists, and create it if not.
[Randy Kobes <randy@theoryx5.uwinnipeg.ca>]

Add a capability to tune the test configuration sections ordering
in Apache::TestConfigPerl [Stas Bekman]

fix the complaining code about late PerlSwitches when PerlLoadModule
is used before it [Stas Bekman]

add various tests that exercise PerlLoadModule and vhosts
[Stas Bekman]

handle correctly PerlLoadModules (directives) with vhosts:
  - handle gracefully cases when things are undef/NULL
  - handle the case when scfg==NULL, by stealing the base_servers's config
[Stas Bekman]

make mod_perl work with vhosts when the server is started prior to
  post_config():
  - call modperl_init_globals as early as possible, because the main server
    record is needed during the configuration parsing, for perlloadmodule
    and vhosts
  - also make sure that we are using a real base_server, when dealing
    with modperl_init, and if not retrieve it from the global record
[Stas Bekman]

prevent segfaults, when scfg is NULL in Apache::Module->get_config();
[Stas Bekman]

ensure that a core file is a file indeed, before complaining [Philippe
M. Chiasson <gozer@cpan.org>]

add $r->as_string [Geoffrey Young]

add backcompat vars: $Apache::Server::CWD and
$Apache::Server::AddPerlVersion [Stas Bekman]

env var MOD_PERL_TRACE is working again [Stas Bekman]

add a new test TestDirective::perlloadmodule2, which performs a more
evolved merging.  [Stas Bekman]

fix Apache::TestConfigPerl under mod_perl 1.0, need to require
mod_perl.pm before using $mod_perl::VERSION [Geoffrey Young
<GYoung@covad.com>]

add an Apache::SIG backcompat stub to Apache::compat [Stas Bekman]

fix the Apache::TestConfigPerl's run_apache_test_config() function
where test packages are scanned for the magic APACHE_TEST_CONFIGURE
and if found get require()'d. Apache2 needs to be run for mod_perl
2.0.  [Stas Bekman]

move the custom mod_perl 2.0 configuration bits out of the
ModPerl::TestRun, where they don't belong, into a special config file
which is included at the very end of httpd.conf [Stas Bekman]

extend Apache::Test to allow extra configuration files to be included
at the very end of httpd.conf, when everything was loaded and
configured [Stas Bekman]

resolve a segfault in Apache::Module::get_config() for the edge case
when the package name is bogus. [Stas Bekman]

Apache::Reload: add support for watching and reloading modules only in
specified sub-dirs [Harry Danilevsky <harry@deerfieldcapital.com>]

enable APR.pm's linking for apr 0.9.2 and higher, which uses a new lib
naming scheme, such as libapr-0.so.0.9.2, only if apr-config and
apu-config scripts exist. [Stas Bekman]

define IoTYPE_RDONLY/IoTYPE_WRONLY for perl-5.6.0 so the project
compiles again under 5.6.0 [Stas Bekman]

allow output streaming filters to append data to the end of the stream
[Stas Bekman]

fixes to compile with ActivePerl 5.8 beta
[Randy Kobes <randy@theoryx5.uwinnipeg.ca>]

fix for directive handlers within vhosts using threaded MPMs
[Stephen Clouse <stephenc@theiqgroup.com>]

fix <IfDefine MODPERL2> support

default AuthType to Basic if not set in $r->get_basic_auth_pw()
[Philippe M. Chiasson <gozer@cpan.org>]

workaround glibc/Perl-5.8.0 crypt() bug (seen with threaded MPMs)

fix delete $ENV{$key} bug

fix parse_args compat method to support non-ascii characters and tr/+/ /
[Walery Studennikov <despair@sama.ru>]

fix post_connection compat method to behave as it did in 1.x
[Geoff Young <geoff@modperlcookbook.org>]

add support for setting $r->auth_name and $r->auth_type
