Apache::SIG enhancements for LogFormat [Doug Bagley <doug@dejanews.com>]

drop API_EXPORTs for mod_include #perl stuff which breaks under win32/1.3b6
spotted by Jeff Baker

Inclusion of $r->server->server_hostname if $r->server->is_virtual in
Apache::Registry script namespaces is back to On by default after
recently tripping up Ben Laurie, Janos Farkas, Tony Bowden.  To
disable (only gain is to conserve memory) in a startup file set:
 $Apache::Registry::NameWithVirtualHost = 0;

work around bloody make problem "don't know how to make Apache.c Constants.c"
spotted on SCO by Krister Keskitalo (along w/ 1-2 others in the past)

[Stefano Santoro <ssantoro@voicetek.com>, Dan Peterson <pete@spry.com>]

removed obsolete src/Makefile.tmpl and src/Makefile.tmpl-Ben-SSL files

new module Apache::ExtUtils, currently with one method to generate xs
code so Apache/Perl modules can add their own directives to Apache rather
than use PerlSetVar (just some more rope, really)

1.3b6 compat:
- deal with ap_ API prefixing
- t/modules/embperl will warn on failure:
>>> NOTE: Be sure to rebuild HTML::Embperl against Apache 1.3b6+
>>> Try 'make test' again after doing so.

experimental: #ifdef PERL_OBJECT_HANDLERS, mod_perl will thaw objects
from Perl*Handler strings such as `$Global::Object->method'

$r->custom_response will now work under win32 with 1.3b6-dev+

added win32 test enhancements suggested by Gerald Richter

added mod_perl_cvs.pod document

=item 1.10 - March 21, 1998

rid of SEGV in PerlChildExitHandler spotted by Eric Cholet

rid of stupid "can't bootstrap Apache::Constants outside of httpd" message

added r->content_languages method

added htdocs/manual/mod/mod_perl.html (generated from Apache::ModuleDoc)

now support <Perl> under win32 (requires 1.3b6-dev+)

PerlChildExitHandler is now implemented via register_cleanup() rather
than the module child_exit hook (which might go away!)

support Apache::Constants tags `override' and `args_how', for Apache::Module

'make test' will now work again under win32

applied Apache::Symbol/Apache::StatINC patches from Chris Dean

fixed bug in Makefile.PL that would tack `aix' onto INCDIR w/ apache
1.2.x, spotted by Mike Klein

removed uneeded check for HTTP_AUTHORIZATION from perl_setup_env()

fixup perl_section_self_boot so it doesn't try to read config
if keys %Apache::ReadConfig:: < 1

perl_section_self_boot thang will now work w/ PerlRequire'd files too

compile @Apache::Constants::EXPORT subroutines at boot time (rather
than AUTOLOAD in each process)

added internal/error.t test to test the new feature below

ErrorDocument's can now access the $@ that threw SERVER_ERROR via
$@{ $r->prev->uri }

added internal/rwrite.t test to test printing of HUGE strings

1.3b6 compat:
- tmp fix for new r->server->names type
- adapt to SERVER_BUILT change to apapi_get_server_built() 
  for Constants.xs

fixed print $HUGE_buffer bug w/ ApacheSSL spotted by Jirka Hejsek 

added WRITE method for tied filehandles

fix so threaded Perl can have <Perl> sections

Perl 5.004_61 dropped -DUSE_THREADS from $Config{ccflags}, Makefile.PL
will now test $Config{usethreads} and add the flag itself

fixed eg/registry.pl sytax erros thanks to David Landgren

fix #ifdefs so we build under win32 again

config files now support =pod/=cut and __END__ in the same fashion Perl does

fix Makefile.PL so it can handle \'ed lines with help from Tom Hukins

Apache::Symbol::handler will skip all Devel::Symdump undef's so
make_universal will work properly

=item 1.08 - February 20, 1998

Apache::Registry will now fold multiple /'s to fix possible bug
spotted by Gerald Richter

fix Apache/Makefile.PL and Constants/Makefile.PL so DYNAMIC=1 works
with 1.3b5 (new include directory)

Constants.xs will now #include mod_perl.h so namespace #undefs are used

fixup some #define clashes on aix thanks to Eric Bartley

fixed Makefile.PL workaround for plucking SSL_INCLUDE with help from
Dan Peterson

can build again with threaded Perl (was just missing a few dTHR's)

cleared up BEGIN/END documenation with help from John Charlesworth

applied patch from Christopher McCrory so -f is also used when 'make
test' httpd is started so it'll work with a .rpm file for a redhat
linux 

added Apache::Constants->name method

fix an #endif; in mod_perl.h thanks to Eric Bartley

mod_perl_cleanup_handler won't try to if(cld) MP_RCLEANUP_off(cld);
#ifdef WIN32 to stop crash spotted by David Hodson

expose stacked handlers to Perl via %Apache::PerlStackedHandlers
(this is only those pushed via $r->push_handlers)

can now tell Makefile.PL APACHE_INCLUDE_INSTALL=0 if you don't want
header files installed

when Apache::Status tries to load optional modules, it will locally
turn off $SIG{__DIE__} to fix bug spotted by Dan Peterson

added SERVER_BUILT to Apache::Constants

got rid of "Use of uninitialized value." warning in perl_util.c seen
when running HTML::Embperl, hunted down by Todd Eigenschink and Gerald
Richter (listed as change in _04, but was lost!)

fixed Makefile.PL so it can deal with metacharacters when copying the
apache source include files, otherwise src.pm breaks, thanks to Dan
Peterson for the spot

=item 1.07_04 - February 10, 1998

fix "building mod_perl by hand" bug w/ 1.3bx spotted by Brian Mosley

no longer force 'PerlSendHeader On' for sub-requests which triggered a
bug spotted by Doug Bagley and Gerald Richter

Fix "Attempt to free unreferenced scalar." during kill -HUP w/
PerlFreshRestart On and <Perl> in httpd.conf spotted by Brian Mosley

clear endav and stacked_handlers on FreshRestart

fix bug spotted by Gerald Richter where Apache->register_cleanup would
cause a core dump

Apache->module will no longer eval "require $module", it will now
return true if the module is in %INC, false otherwise

fix so END blocks encountered at startup are run at shutdown
(I think one of the 1.07_xx version broke it)

If exists, Makefile.PL will add /usr/local/stronghold/conf/httpd.conf's
StrongholdKey to t/conf/httpd.conf for 'make test' for you

Makefile.PL will edit Stronghold's Makefile to replace:
"CFLAGS=$(CFLAGS)" with 'CFLAGS=$(CFLAGS)' so the SUBVERSION thang works

fix $r->custom_response problem spotted by Brian Mosley so it works
with SERVER_ERROR

added new method child_terminate

fix $r->current_callback so it can be called during startup

perl Makefile.PL PERL_DEBUG=1 will:
-add `-g' to EXTRA_CFLAGS
-turn on PERL_TRACE
-set PERL_DESTRUCT_LEVEL=2
-link against libperld if -e $Config{archlibexp}/CORE/libperld$Config{lib_ext}

Apache::Constants :common export tag no longer includes
OPT_EXECCGI (was held off from 1.07_01's Changes Apache::Constants
cleanup waiting to make sure HTML::Embperl and Apache::ePerl didn't
rely on OPT_EXECCGI to be exported by default.  both look fine now)

added workaround Apache::RedirectLogFix module to work around the
re-introduced log bug below

to fix a double-header send bug spotted by Doug Bagley, backed out
this Change from 1.06: 
 Apache::Registry will return REDIRECT if $r->header_out("Location")
 so the request is logged properly, thanks to spot by Jon Drukman

added experimental PerlRestartHandler 
(enabled with PERL_RESTART_HANDLER=1, note: _not_ enabled with EVERYTHING=1)

moved Apache::sv_name function to the new Apache::Symbol package

Apache::StatINC will call Apache::Symbol's undef_functions method for
.pm classes if PerlSetVar UndefOnReload is On

before re-compiling, Apache::Registry will now check if 
$package->can('undef_functions'), if so, invoke that method

added Apache::Symbol module with an undef_functions method

Apache->server_root_relative now defaults to "" when no
filename/directory name argument is given (ie returns ServerRoot)

made PERL_TRACE more useful with levels set via environment variable
MOD_PERL_TRACE:
d - trace directive handling during config read
s - trace processing of perl sections
h - trace Perl*Handler callbacks
g - trace global variable handling, intepreter allocation, END blocks, etc.
all - all of the above

will add -DSTRONGHOLD to CFLAGS if build against stronghold, thanks to
Todd R. Eigenschink

fix Makefile.PL's parsing of SERVER_SUBVERSION, spotted by Paul Sutton

$r->send_http_header can now accept an optional second argument, if
present will set $r->content_type

PerlPassEnv, PerlRequire and PerlModule now use an array_header
structure for internal storage

1.3b4 compat:
- adapt to new table api changes (with help from Rob Hartill and Dean Gaudet)
- adapt to *.h move to the new src/include directory

Apache::Status enhancements:
- "Loaded Modules" will now report last modified time
- "packages" are now links, click, symbol table dump
- now that packages are links, no longer do recursive dump
  (recurse yourself via hyperlinks, much easier to read!!!)
- hashes, scalars and arrays are now links, 
  click, Data::Dumper Dump (only if PerlSetVar StatusDumper is On)
- functions are now links, click, subroutine info (requires the B module)
- dump of any type also has a link "Peek Dump"
  (only if PerlSetVar StatusPeek is On and Apache::Peek is installed)
- dump of any type also has a link "OP Tree Graph" 
  (only if PerlSetVar StatusGraph is On)
  (requires the B and B::Graph modules and the dot program)
- added t/modules/status test

with the -DPERL_MARK_WHERE experimental feature enabled, there's a
chance you'll never see "Use of uninitialized value." again without
some more useful information, nor will you see '-e' reported outside
of Apache::Registry

perl_destruct_level can now be set via the environment variable
PERL_DESTRUCT_LEVEL or -DPERL_DESTRUCT_LEVEL

turn default perl_destruct_level down from 2 to Perl's default of 0

use a copy of apache's ap_cpystrn against versions < 1.3b4-dev

got rid of "Use of uninitialized value." warning in perl_util.c seen
when running HTML::Embperl, hunted down by Todd Eigenschink and Gerald
Richter 

added modules/src test for Apache::src

documented Apache::src

the Apache::src->new method will now default to the first
auto/Apache/include directory found relative to @INC

the apache header files (*.h) will now be installed in 
$(INST_ARCHLIB)/auto/Apache/include

fix $Apache::ServerStarting bug that broke 'make test' w/ ApacheSSL
and Stronghold spotted by Vivek Khera

remove the need for File::Copy's mv() function, since it can't seem to
decide if it has one or not

_03's new tests assumed PerlCleanupHandler was enabled, fixed now
thanks to spot by Rob Hartill

Makefile.PL will now chmod a+x t/net/perl/* t/net/perl/io/*
thanks to Rob Hartill 

experimental features can be enabled with -DDEFINEs instead of
$variables or %ENV, changes to Makefile.PL make them simple to add,
see eg/makepl_args.mod_perl for even simpler

added eg/makepl_args.mod_perl

the makepl_args.mod_perl can now have multiple lines, space, #comments
and empty newlines are ignored, stops reading if it hits __END__

Makefile.PL will now also look for $ENV{HOME}/.makepl_args.mod_perl
and read in if exists

before clearing handlers stacked via Apache->push_handlers at the end
of each request, save the PerlChildExitHandler stack and putback after
the clear.   this way, modules pulled in at server startup can say:
Apache->push_handlers(PerlChildExitHandler => sub {})

a "top-level" mod_perl per-directory directive would cause core dump
inside <Perl> sections.  now trap that and exit with message that the
directive should be inside a containter e.g. %Location, %VirtualHost
(not sure what the real problem is here)

re-work PERL_SECTIONS_SELF_BOOT stuff so it calls perl_section() directly,
rather than perl_eat_config_string("<Perl>\n</Perl>"), because:
- it no longer core dumps when a "top-level" per-server directive is found
- it no longer requires 1.3b3+ (1.2.x will work)
- it is faster

PerlModule/PERL_SECTIONS_SELF_BOOT will delete $INC{$PerlModule} on
the first config read pass, so it's re-read on the second pass

if ($] < 5.004_04) Makefile.PL will warn that users should upgrade to
5.004_04 or higher 

removed Apache::PerlSections' self test now that we have
modules/psections.t and it won't work without the =pod line.

remove =pod line from Apache:: modules (SIG, fork, Resource,
PerlSections) to stop 5.004's pod2man's bogus warnings spotted by  
Eric Cholet 

fixed but in $r->get_remote_host, which was forcing the default type
REMOTE_NAME even if another type was passed as the optional second argument

renamed eg/perlio.pl to eg/test.pl

moved SUPPORT section from INSTALL doc to it's own file

fixed auto-set of $ServerRoot bug in Apache::httpd_conf

get rid of -Wall warning in Apache::sv_name

=item 1.07_03 - January 8, 1998

removed "[notice] mod_perl restarted" message since it doesn't go to
the error_log as it should, spotted by Vivek Khera and Paul Phillips

fixed corrupted $ENV{TZ} spotted by Michael Parker

cut out 'make test' error_log noise, anything there now should only be
an error or a non-error [notice]

make Apache::Resource simpler to configure, to use w/ all defaults
(1.3bx + PerlChildInitHandler required):
PerlSetEnv PERL_RLIMIT_DEFAULTS On
PerlModule Apache::Resource

Makefile.PL will now:
mv "t/conf/httpd.conf", "t/conf/httpd.conf.old" 
so httpd.conf is re-generated when Makefile.PL is re-run

added new module Apache::src for finding it and picking out bits-n-pieces

get rid of some <Perl> section warnings with help from Doug Bagley

improved register_cleanup tests

applied $r->register_cleanup patch from Doug Bagley to properly call
MP_RCLEANUP_off after cleanups are run

perl Makefile.PL can now accept ADD_MODULE, Makefile.PL will (s/,/ /g)
and uncomment the list of modules from src/Configuration
 e.g.:
 ADD_MODULE=unique_id,proxy,info

perl Makefile.PL can now accept PERL_EXTRA_CFLAGS, Makefile.PL will 
(s/,/ /g) which are added to EXTRA_CFLAGS
 e.g.:
 PERL_EXTRA_CFLAGS=-DFOO=1,-DBAR=2

if the file `makepl_args.modperl' is present in . or .. it will be read into
@ARGV, e.g. might contain EVERYTHING=1 DO_HTTPD=1

fixes for 1.3b4-dev compat
- get rid of AuthName space in generated .htaccess file for
  internal/hooks test

if a PerlModule defines something in %Apache::ReadConfig <Perl>
sections are run without need to actually have <Perl></Perl> in
httpd.conf, i.e. httpd.conf could be nothing more than:
 PerlModule Apache::httpd_conf
whilst experimental, enable by setting the envrionment variable 
PERL_SECTIONS_SELF_BOOT to something true

experimental feature, modules can 'exit|die AUTH_REQUIRED;' or with
any HTTP error code and that response is sent rather than SERVER_ERROR
to test enable by setting $Apache::ERRSV_CAN_BE_HTTP = 1

take CGI.pm version check out of Apache::Registry, now that we require
5.004+, they'll have at least 2.36

get rid of "Use of uninitialized value at -e line 65535" warning
caused by perl_run_rgy_endav() spotted by Doug Bagley

if there is an error inside <Perl>, filename and line number are now
displayed in the error message, e.g.
syntax error at t/conf/httpd.conf line 25 
 instead of
syntax error at (eval 1) line 2

Apache::RegistryLoader->handler will now strip leading '/' when $uri is
server_root_relative and no $filename is present

Apache::Status menu item "Perl Section Configuration" 
(only if $Apache::ReadConfig is true)

added Apache::Status menu item "Enabled mod_perl Hooks"

added mod_perl.pm functions hook() and hooks()

go back to internal <Perl> sections package name ApacheReadConfig

Apache::PerlSections stuff:
- added handy store method for writing dump() to disk
- fixed self-test
- updated docs to reflect new output format

Apache::test stuff:
- added run method
- added MM_test method for Makefile.PL's to say:
  *MY::test = \&Apache::test::MM_test

some httpd_conf.pm stuff:
- added server_url method
- added catch_signals method to terminate httpd on __DIE__ or INT
  ($conf->server_start calls this by default)
- when httpd.conf is written, set BaseDir in a BEGIN block
- drop trailing slash from Alias'
- fix write() method's assignment of %$self to *Apache::ReadConfig:: 

fix possible core dump when calling gv_fetchmethod()

=item 1.07_02 - December 22, 1997

output of Apache::PerlSections->dump is now suitable to be eval'd

added Apache->httpd_conf method (just pushes into
@Apache::ReadConfig::PerlConfig and requires 1.3b3+)

renamed package <Perl> sections are proccessed in 
from ApacheReadConfig to Apache::ReadConfig

ensure values of %Location keys, etc. in <Perl> sections are HASH refs
to stop possible core dump spotted by Stuart Frew

filename 

added new Constants CONTINUE and NOT_AUTHORITATIVE as aliases for DECLINED 

change the `PerlScript' directive name to `PerlRequire' as suggested
by Dick Hardt (PerlScript will still work, but is not documented)

set variable $Apache::ServerStarting to 1 during perl_startup()

set variable $Apache::ServerReStarting to 1 during perl_restart()

Apache::SIG->set is now called at server startup by default

applied patch from Doug Bagley to stop possible infininite loop in
Apache->read 

create stacked_handlers = newHV() before modules are loaded,
so PerlModule's can do things like:
   Apache->push_handlers(PerlChildInitHandler => sub {
	srand(time ^ $$);
   });

$r->args can now be modified as suggested by Joel Truher

remove obsolete (and broken) iedit of t/net/perl/cgi.pl thanks to

get rid of "use of uninitialized value" from <Perl></Perl> pointed out
by Joel Wagner

fixed strict refs bug in Apache::PerlSections spotted by Brian Mosley

Apache::Registry will return REDIRECT if $r->header_out("Location")
so the request is logged properly, thanks to spot by Jon Drukman

call mod_perl_pass_env() during perl_startup() so PerlScript and
<Perl> sections can see PerlPassEnv variables

mkdir t/logs so we can run tests with ApacheSSL 

Makefile.PL will add -I$(SSL_BASE)/include to EXTRA_CFLAGS for ApacheSSL

fix core dump with 1.3b3-dev

If Apache::SIG is set, don't install the default $SIG{PIPE}="IGNORE"
 
added PerlPassEnv directive suggested by Joel Wagner

stop core dump in Apache::exit spotted by Joel Wagner if called as a

Apache->request($r)  

fixed bug spotted by Roland Friedwagne where CGI.pm-2.37bx's header()
method (Apache->send_cgi_header underneath) would not work unless
PerlSendHeader was On (added new tests to internal/headers.t to make
sure from now on!)

applied patches from Peter Tillemans so we can run the test suite
under win32

applied win32 patches from Peter Tillemans so perl_handler() is mutex
locked and to cut out Makefile.PL attempt to symlink the eg directory

Apache::test will define the bootstrap method for Apache and
Apache::Constants to quiet 'make test' noize spotted by Andreas

=item 1.05 - 11/06/97

no longer include $r->server->server_name as part of the
Apache::Registry uri->package name translation by default.  if you
*really* need this to happen set this in PerlScript:
 $Apache::Registry::NameWithVirtualHost = 1;
and, please tell me why you need it, we'll figure out a better way

yanked DeleteINC thingy from StatINC

applied patch from Randal Schwartz so StatINC doesn't loop when it has
to reload itself

disable CV cache of stacked handlers for now, they stick around too 
long, e.g. Apache::StatINC won't work, thanks to Randal Schwartz for
spotting this

applied patch from Ben Reser so $r->send_fd returns the length (as it
should have been doing)  

added current_callback() method handy for PerlDispatchHandler's

added suggestion from Andreas for a PerlDispatchHandler hook

re-worked code in perl_load_startup_script() that was causing IRIX 6.x
to choke when saving dowarn, thanks to Lasse Petersen for tracking
this down

fixed newline eating bug spotted by Eckard Brauer when headers and
body are sent in the same print() statement

renamed 'core' test directory to 'internal'

remove t/TEST's search for obsolete directories, which caused trouble
on IRIX 6, spotted by Lasse Petersen 

for internal redirects (spotted by $r->cgi_header_out), don't
perl_call_halt(), instead, tie STDOUT to the Apache::FakeRequest class
which just soaks up print() output.

suggestion from Salvador Ortiz Garcia, for table methods, if value is
undef, call table_unset underneath, these methods are subprocess_env, 
header_in, header_out, err_header_out, notes and dir_config. e.g.:

 $r->header_out("Content-length" => undef);

ensure constant subroutine re-definition warnings are surpressed
during restart (when PerlFreshRestart On), spotted by Vivek Khera

added Apache::FakeRequest module

added tests for embperl and eperl

applied patch from Lupe Christoph so Makefile.PL will not throw out
-DSERVER_SUBVERSION if present in apache_x.x.x/src/Configuration

fixed bug in Apache->send_cgi_header that was sending headers twice
with "here" docs, spotted by Leonard Megliola

Apache->server->log_error will return undef if logs are not open yet
as suggested by Mike Fletcher

fixed typo bug in Apache::Status spotted by Brian Tiemann

=item 1.04 - 10/30/97

PerlScript and -Mmod_perl are no longer handed to perl_parse(),
instead perl_parse() gets a -e to set $ENV{MOD_PERL} and
$ENV{GATEWAY_INTERFACE} (and possibly other switches -T, -w)
PerlScript is pulled in via 'do $PerlScript';

applied patch from Ron Hawkins to fix bug in perl_setup_env() when
running with Stronghold in secure mode

added Apache::PerlSections module, currently with one method: dump()

for use in <Perl> sections, PerlScript and PerlModules, can now say 
'my $s = Apache->server' during server startup, which returns a
server_rec* blessed into the Apache::Server class just as $r->server
does during request time.   

Apache::Server class can now warn() and log_error()

avoid using LWP::Simple so we don't get caught up on HTTP_PROXY which
was cause 'make test' to fail several tests for some people.
thanks to Philippe Froidevaux, Tom Hughes and Frank Cringle

added some 3rd-party tests for Apache::Stage and Apache::Sandwich

added Apache::test module

back out support for internal redirects, caused big problems with
sfio-enabled Perl spotted by Lupe Christoph and Salvador Ortiz Garcia 
(can still try by setting $Apache::DoInternalRedirect=1 #ifndef USE_SFIO)

added Apache::SIG module for testing

Apache::exit will not rflush if r->connection->aborted

updated Vivek's mod_perl_tuning.pod

now that 1.3b3-dev config gears are not tied so tight to a FILE*,
<Perl> sections may define $PerlConfig and/or @PerlConfig, who's
string values are fed to the apache config  

some mod_perl.pm fixes

Apache::Status "Loaded Modules" item enhancements:
-now shows file location
-can click on module package for dump of it's symbol table
-pretty table format

don't add -I. to perl_startup() which may cause confusion spotted by
Mike Fletcher

make _sure_ perl_per_request_init() is called for sub-requests so
everything works properly, e.g. Action or a mod_include'd #perl
thanks to Peter Levart and Scott Holdren for spotting this

=item 1.03 - 10/23/97

configure/build/INSTALL enhancements with much help from Bowen Dwelle:
- to use an apache Configuration file that mod_perl will not edit:
  perl Makefile.PL CONFIG=Configuration.custom

- perl Makefile.PL DYNAMIC=1 ALL_HOOKS=1 ...
  Configure mod_perl with ../apache_1.2.4/src ? [y]
  Shall I build httpd in ../apache_1.2.4/src for you? [y] n   
  now, $APACHE_SRC/modules/perl/Makefile will be enabled with those hooks
 
- to aid EXTRA_CFLAGS when building by hand or using a custom
  Configuration file: `perl -Mmod_perl -e subversion` prints:
    SERVER_SUBVERSION=\"mod_perl/$mod_perl::VERSION\"

- fixed up INSTALL quite a bit

added $r->post_connection alias for $r->cleanup_handler

if 1.3b2+, drop log_error(), use new aplog_error() instead (everywhere)

if Tie::IxHash can't be loaded for <Perl> sections, don't complain

applied patch from Rob so mod_perl.pm is in the tar_Apache target

removed Apache->request depreciation warning

added redirect.t test to test remote redirect and internal redirects

fixed internal re-direction handling of Location: /local/file.html

removed several eg/ scripts that were "ports" of CGI.pm-x.xx/examples 
now that CGI.pm runs solid under mod_perl and mod_perl requires
5.004+, there's no need for $r->print and CGI::Switch, so those
examples don't need "porting"

force 'PerlSendHeader On' for sub-requests, e.g. Apache::Sandwich
so headers don't show up in the browser

fixed PerlSendHeader bug with virtual includes spotted by Scott Holdren

make lib/mod_perl.pm -> mod_perl.pm symlink (for 'make test') relative,
suggested by Bowen Dwelle

applied patch from Andreas to add a new $r->subprocess_env method

fixed Apache::StatINC brokeness spotted by Bowen Dwelle and applied a
StatINC doc patch from him too

the Apache::Registry cache 
(must set 'PerlFreshRestart On' in httpd.conf for this to work)
 
=item 1.02 - 10/17/97

have Makefile.PL edit t/net/perl/cgi.pl's #! line to fix perl location
thanks to Frank Cringle for spotting this

=item 1.01 - 10/16/97

removed undocumented auto-import of qw(OK DECLINED) use to short-cut
Perl*Handlers and/or apache C handlers, use Apache::OK and
Apache::DECLINED instead

start perl interpreter with -Mmod_perl so _every_ module no matter
where it's loaded from will see $ENV{GATEWAY_INTERFACE} and $ENV{MOD_PERL}
Thanks to Mark Dedlow for illustrating this need with Apache::DBI and friends.

<Perl> section %Hash values of hash refs now go through
perl_handle_command_hv(), so `Location' can be inside %VirtualHost,
etc.  Thanks to Ask Hansen for spotting this. 

<Perl> section %Hash values of array refs now go though
perl_handle_command_av(), so proper action is used on TAKE1, etc. 

if Tie::IxHash is available, tie <Perl> section %Hashes to it, so the
apache config routines get info in the order it needs to.  Thanks to
Rob Hartill and Dean Gaudet for explaining this need for 1.3bx's
new virtual host features

include the mod_perl logo image (mod_perl.gif)

ensure _all_ stacked handlers registered with $r->push_handlers() are 
cleared after each request to fix bug spotted by Peter Lister

test suite will now delete $ENV{HTTP_PROXY} before running,
thanks to Frank Cringle

Apache::Registry args changes:
-$_[0] is the blessed Apache request_rec
-$_[1..-1] are args from Apache::Include::handler or elsewhere 
           as suggested by Andreas

added tests for Apache::Include

applied Apache::Registry optimization patch from Andreas

Apache/Apache::Constants no longer ISA Exporter,
just alias *import = \&Exporter::import

test suite re-org

write a mod_perl.pm so we can require a mod_perl min version 
and hooks/features ala
 use mod_perl 1.01;
 use mod_perl 1.01, qw(Authen Authz);

new Apache::RegistryLoader to pre-load Apache::Registry scripts

added Apache::Include->virtual($uri) method

1.3b1 stuff:
-cat apache_x.x.x/src/Makefile.config and src/modules/perl/Makefile
 together so we get $(INCLUDES) (for os/unix, etc)

applied patch from Salvador Ortiz Garcia so calling $r->args in an
array context will not produce "Odd number of elements in hash list" 

$r->auth_name can now be modified

remove Apache->send_cgi_header's broken internal re-direct handling
spotted by Debby Fu

added Frank Cringle's mod_perl FAQ 

added mod_perl_tuning.pod document from Vivek Khera <khera@kciLink.com>

fixed bug spotted by Brian Millett so stacked handlers work again with
Apache-SSL

set environment variable `MOD_PERL' so scripts can say:
if(exists $ENV{MOD_PERL}) { ...

added suggestion from Rob Hartill:
'PerlSetVar MaxModPerlRequestsPerChild 10' behaves like
MaxRequestsPerChild, but counts mod_perl requests only.  1.3b1-dev+ is
needed for this

=item 1.00_03 - 09/21/97

save %SIG before perl_handler (Apache::Registry) is run, restore
afterwards as suggested by Randal Schwartz

fixed virtual host/Apache::Registry bug introduced in _02,
spotted by Ryan A. Whelan

a few win32 fixes:
- skip uid,gid,etc., in perl_init_ids 
- fix ApacheModulePerl.dsp for source re-org

if PerlSendHeader is On, the environment variable PERL_SEND_HEADER is
set to `On'

=item 1.00_02 - 09/15/97

1.3b1 stuff:
- $r->warn and $r->log_error go through new aplog_error() function.
  If `LogLevel' is not set to `warn' or higher, $r->warn messages are
  ignored (not sent to error_log). 
  (i.e. $r->warn == APLOG_WARNING, $r->log_error == APLOG_ERR)
- always enable child_init/child_exit
  + use child_init for perl_init_ids() 
  + use child_exit to: 
     -run END blocks suspended at server startup
     -run perl_destruct(), now global objects will be DESTROYed
- make sure mod_include can find modules/perl/mod_perl.h if PERL_SSI=1
- fix INCDIR in src/modules/perl/Makefile
- rename libmodperl -> libperl for new Configure changes

applied Apache->read patch from Evert-Jan Couperus to use lvalue
substr() instead of .=

Apache->seqno will no longer dig into scoreboard info for rec.my_access_count
the seqno method was originally introduced for CGI.pm, which now uses
$r->register_cleanup instead.  It was never documented in Apache.pm,
does anyone actually use Apache->seqno?

perl_section() will call perl_startup() if Perl's not running already,
as suggested by Rob Hartill

included t/conf/httpd.conf.pl for testing <Perl>, which can replace
t/conf/httpd.conf if you've configured with PERL_SECTIONS=1

various documentation updates 
- document END blocks behavior
- added "Additional memory tips" section to mod_perl.pod

- other stuff here-n-there

applied patch from Ulrich Pfeifer so Makefile.PL does not eat args for
MakeMaker, e.g. PREFIX=~

mod_perl now requires Perl version 5.004 or higher

hookup STDERR to error_log first chance we get (first Perl*Handler
that's called)

$r->warn and $r->log_error will now join @_ and log one string instead
of calling log_error foreach @_, suggested by Joel Wagner

PerlScript may now be relative to ServerRoot

remove UNIVERSAL::AUTOLOAD from Apache::Debug (more trouble than help!)

make sent_header variable per-directory instead of global

added $r->bytes_sent method suggested by Maurice Aubrey
along with code from Nathan Torkington to make sure we get it right as
mod_log_common does 

added fix to Apache::Include from Randal Schwartz so $r->uri is
properly reset 

SetEnv PERL5LIB will now work on a per-directory basis thanks to spot
by Vivek Khera

if PERL_SSI=1 only do `perl -MExtUtils::Embed -e ccopts` once instead
of for every .c file!  nudge from Rob.

applied Makefile.PL patch from Rob Hartill to prompt for most recently 
modified apache*/src directories first

now suspend all END blocks encountered during server startup and run
them during server shutdown aka child_exit (need 1.3b1+)

now execute END blocks of PerlHandler (Apache::Registry) scripts at
the expected time

make sure CGI.pm version 2.36 or higher is being used

make sure GATEWAY_INTERFACE is not cleared from %ENV so
Apache::DBI/ApacheAuthenDBI work together, thanks to spot by 
John Groenveld

some source re-org: split stuff into perl_util.c and perlio.c, 
rename config.c -> perl_config.c, various cleanups

the constants.t test is now run under httpd with t/net/constants.pl

Apache::Constants not longer defines subs at startup.  we now use a C
AUTOLOAD which creates newSUBs when needed, without eval {} and
without "prototype mismatch" errors.  This shrunk my httpd image size
by ~50K

according to Joel Wagner, Solaris's tar did not like the trailing / on
the Apache/ argument to the tar_Apache target in Makefile.  gone now.

thanks to help from Vern Hart, Apache::Registry will now include
$r->server->server_name as part of the uri->perl package translation
if $r->server->is_virtual  

$0 is now set to $r->filename thanks to spot by Dylan Tynan

added auth.t test to the suite

moved constants/export.t to net/constants.t
 
$>, $<, $) and $( are now properly initialized, thanks to bug spot by
James Freeman 

applied Constants.{pm,xs} patch from Gisle Aas, adding some new
constants from httpd.h, :methods import tag and some cleanups

applied Makefile.PL patch from Andreas Koenig adding verbosity
if there's a problem with t/report

PerlNewSendHeader functionality has replaced PerlSendHeader's
the `PerlNewSendHeader' directive is gone, replace with `PerlSendHeader'

fixed Apache::exit so it no longer calls C-level exit (unless exit
code == -2), it now just terminates the perl callback, without
producing an "Internal Server Error" therefor, we complete _all_
post-handler request phases and no longer dump core, as some have seen
under certain conditions.  the test suite nows tests calling exit()

applied patch from Brian Millett to Makefile, so SSL_CFLAGS are used
with Ben-SSL 

=item 1.00 - 07/28/97 

some 1.3a1 compatible things:
- mod_perl is now a dll under win32 
(Extra thanks to Gurusamy Sarathy for fixing Perl so this works)
- cope with limit() -> limit_section() rename
- API_EXPORT perl_call_handler and perl_stdout2client for mod_include/win32
- added win32 dirent.h kludge to workaround conflict(s) between perl's
  dirent.h apache's readdir.h  
- -Wall clean again

added new sub request methods:
- lookup_uri (sub_req_lookup_uri)
- lookup_file (sub_req_lookup_file)
The returned request_rec * is blessed into the `Apache::SubRequest'
class so destroy_sub_req() is called automatically during DESTROY
- the run_sub_req() function is available in this class as the run() method 

added patched Makefile.tmpl-Xcert from Vivek Khera to support XCert's Stronghold Sentry

$r->cgi_header_out should do case-insensive checks, 
bug spotted by Ralf Engelschall

eval { bootstrap Apache::Constants } so perl -c works outside of httpd

added `PerlChildExitHandler' callback hook (requires 1.3a2-dev or higher)

added `PerlChildInitHandler' callback hook (requires 1.3a1 or higher)

don't enable PERL_SECTIONS or PERL_SSI unless apache version >= 1.2.0
thanks to hint from Vivek Khera

removed Makefile-1.2 (don't need one anymore!)

removed Apache->connection->close method which _nobody_ should still have
their code  (it has produced a warning since 0.93_01 - 03/04/97)

added Apache->connection methods local_addr() and remote_addr() thanks to
Eric James Negaard 

applied patch from Hakan Tandogan so mod_perl's Makefile picks up SSL_INCLUDE

=item 1.00b2 - 07/07/97

fixed scoping bug in Apache::Registry spotted by Marshall Dudley

append LockFile to t/conf/httpd.conf if SERVER_VERSION >= 1.2.1

add ''s for CC='$(CC)' workaround for bug spotted by David Lloyd and others

added Apache::Debug->import so 'use Apache::Debug level => 4' will:
-level sets $Apache::Registry::Debug
-define UNIVERSAL::AUTOLOAD to stop spinning when undefined sub is called
-Carp::confess instead of die()
-allocate $^M if $Config{cflags} =~ /EMERGENCY_SBRK/

croak() if should_client_block() to prevent spin into "Out of memory!"

make compatible with 1.2.1 r->read_length change so we don't hang
on file uploads

can't run 'make test' as root with 1.2.1, if user `nobody' exists,
use that, otherwise prompt user for `User' and `Group' as suggested by
Michael Parker   

Andrew Tennant reported that `PassEnv' didn't work.
we now turn off %ENV magic when clearing %ENV so it does work

win32 stuff:
-include handy patch for modules.c as there's no win32 Configure script yet
-fixed mod_perl.h mutex #define broken-ness

the following will now work as expected (building {Apache,Constants}.s[ol]):
 perl Makefile.PL NO_HTTPD=1 DYNAMIC=1 && make
thanks to hints from Bowen Dwelle

added Makefile.PL option where 'perl Makefile.PL EVERYTHING=1'
will enable all features:
ALL_HOOKS, PERL_SECTIONS, PERL_STACKED_HANDLERS, PERL_METHOD_HANDLERS, PERL_SSI

fixed cgi_to_mod_perl.pod mess

added AIX note from Eric Bartley to the INSTALL doc

swap link order of Makefile.tmpl for Stronghold, regardless of version,
thanks to Ted Corning

perl_clear_env() will now leave $ENV{TZ} in place to 
cure bug with hpux 9.04 spotted and suggested fix from
1Lt. Samuel S. Tai 

Apache::Registry will now 'chdir dirname $r->filename' before the 
script/subroutine is compiled so 'use Foo' can find Foo.pm in '.'
bug spotted by Janne Himanka

win32 port:
-added INSTALL.win32
-added src/modules/perl/mod_perl.mak
-tweaked Makefile.PL:
  -does not try to build httpd 
  -generates perlxsi.c, Apache.c, Constants.c (since we use mod_perl.mak)
-Apache::Registry does not test '-x $filename' if $Is_Win32 
-wrap callbacks in a mutex lock/unlock

applied patch from Eric Bartley to fix Apache::Include

change Apache::Registry behavior back to returing $r->status instead of OK

=item 0.99

fix bug with PERL_METHOD_HANDLERS spotted by Eric Bartley

=item 0.98_12

applied patch from Alexander Demenshin <aldem@techie.com> to plug
leaks in perl_{stdout,stdin}2client

can now say 'perl Makefile.PL PERL_SSI=1' to enable mod_include stuff

the link order of apache 1.2b12-dev has been switched back to the way
it was in b10, now we only have to muck with Makefile.tmpl if $Is_b11

once again, ensure CGI.pm knows GATEWAY_INTERFACE if it is use'd in a
PerlScript, thanks to Tom Hughes for spotting this

removed trick to make `require Apache::TieHandle' a noop, *nobody*
should still have that in any code, if so, sorry, get rid of it!

inspired by Pai-Ling Hsiao, added tiny Apache::Include module so the
mod_include <--!#perl directive can take advantage of
Apache::Registry, like so: 

 <!--#perl sub="Apache::Include" arg="/perl/ssi.pl" -->

added $r->translate_name method to run translate handlers

fix Apache::Status so it sends http headers!  spotted by Mike Stok

have cgi.t skip it's tests if CGI.pm is not installed, for Rob, the

=item 0.98_04

added BSDI dynamic loading notes from Gary Shea <shea@xmission.com> to
the INSTALL doc 

added PRINTF method (again!) for tie'd STDOUT, spotted by Kristina Helen Long

the following stuff now works inside <Perl></Perl> sections:
- %VirtualHost, %Files and %Directory 
- implemented <Limit GET POST> sections like so:
$Location{"/~dougm/"} = {
    AuthUserFile => '/tmp/htpasswd',
    AuthType => 'Basic',
    AuthName => 'Homepage',
    Limit => {
	METHODS => 'GET POST',
	require => 'user dougm',
    },
};
- `PerlModule' configuration directive

set $SIG{PIPE} = 'IGNORE'; when the server starts to avoid hosing when:
 `Apache->print lost connection to client'
thanks to Aaron Flin for the tip

=item 0.98_03 - 05/19/97

construct Perl interperter the first time perl_startup is called
rather than the second:
-slapped self upside head wondering why I did not do this before
-now -DAPACHE_SSL for Stronghold or Ben-SSL does not matter
-<Perl></Perl> sections work again
-ugly avoid_first_alloc_hack is gone!
 
added `ENVIRONMENT' section to mod_perl.pod

added `PerlSetEnv' configuration directive

back to only PerlHandler enabled by default 

if STATIC=1 is configured during 'perl Makefile.PL', Apache::Constants
will also be linked static.  This is the default on aix and bsdos.

$r->register_cleanup will now save a pointer to the request_rec
rather than doing it in PerlTransHandler

applied patch from Martin Pool <m.pool@pharos.com.au> so we see the real
line number if something goes wrong in an Apache::Registry script

now add -I./ and -I$Config{archlibexp}/CORE to EXTRA_CFLAGS for
mod_include integration

=item 0.98_02

$r->send_http_header now resets $r->status to 200 after calling
send_http_header() to squash double header w/ Location: bug 
spotted by Jonathan Lieberman

added $r->cgi_header_out so we can _really_ send headers the way
mod_cgi does (e.g. Set-Cookie bug spotted by Jonathan Lieberman)

=item 0.98_01

made room for args in perl_call_handler() for mod_include integration
in the future, this can be used to pass arguments to Perl*Handlers:

   PerlHandlerArgs Package::sub_name  OneArg TwoArg RedArg BlueArg 
   
split out some config routines from mod_perl.c to config.c

fixed bug in Apache/Makefile.PL thanks to Jeff Rowe

now use translate slot to do some initialization

Perl*Handlers can now be anonymous subs (need 5.003_98+), e.g.:

 PerlFixupHandler "sub { shift->header_out(Key => 'val') }"

finally get cleanups right:
- PerlCleanupHandler is now run during PerlLogHandler
- new method $r->register_cleanup uses register_cleanup
  underneath and is always available

@INC is now reset to default after each request

fixed "const char *" bug in typemap spotted by Honza Pazdziora 

=item 0.98 - 05/02/97

save a pointer to request_rec in the translate stage so we always have one
for PerlCleanupHandler (e.g. no PerlHandler first), tracked down by Eric Bartley

PerlTransHandler enabled by default now

don't use server_argv0 when intializing perl_startup's argv[], caught by Andreas

remove headers.t, will bring back in 0.98_01 and flesh out PerlNewSendHeader

fix bug in $r->requires, caught by Eric Bartley

go back to $|=1 #ifdef USE_SFIO, caught by Salvador Garcia

=item 0.97_02 - 04/29/97

added documentation for stacked handlers and a little for method handlers.

$^X is now set to server_argv0 as suggested by Frank Cringle

Apache::Registry will now require CGI.pm version 2.35 or higher if you
are using it.  Makefile.PL will also test and warn if it is < 2.35

removed examplish modules from the distribution into the contrib directory: 
AuthzAge.pm, AccessLimitNum.pm, MsqlProxy.pm, SSI.pm
the contrib directory will be tar'd and uploaded to CPAN when updated.

added headers.t test for Perl(New)SendHeader

added option to link httpd with static Apache.o (the original way), 
(Eric Bartley reported problems on aix with Apache.so, others?)
like so:  perl Makefile.PL STATIC=1

only bother setting $$ once per-child

%ENV is now cleared by a registered cleanup function, rather than
after PerlHandler is called

applied patch from Andreas to ensure APACHE_SSL is defined if
we're configuring with it 

putback -DSERVER_SUBVERSION now that netscape workaround is in 1.2b9

PerlNewSendHeader enhancement so headers don't need to be part of
a single print statement.

applied fix from Rob Hartill so Makefile.PL can parse beta version >= 10!

properly initialize cld->new_sendheader thanks to Rob Hartill

$r->print is now an xsub for speedup, even with the new
extra operation of checking $|, it's faster:

 Benchmark: timing 100 iterations of 0.97_01, 0.97_02...
    0.97_01:  9 secs ( 2.03 usr  0.19 sys =  2.22 cpu)
    0.97_02:  8 secs ( 1.84 usr  0.17 sys =  2.01 cpu)

sfapachewrite() will now call Apache->print 

if $| is non-zero, call rflush() after writing to the client

$| is reset to 0 before PerlHandler is called

applied patch from Eric Bartley to:
-add get_remote_logname() method
-update Apache.pm documentation including:
 get_remote_logname, auth_type, auth_name, document_root, notes

fix so $r->rflush works with older apache's

=item 0.97_01 - 04/22/97

added experimental `PerlNewSendHeader' config directive
works like `PerlSendHeader', but scans headers for special
headers like Location:, Status:, etc.
simply uses a C global variable `sent_header', if true, sends
data asis to client, otherwise calls $r->send_cgi_header 
currently, does not work with sfio (yet) and this only works if a
single print statement sends  the headers like so:

 print "Status: 302\n", 
       "Location: http://www.somewhere.com/\n",
       "Content-type: text/html\n\n";

"fixed" new preg* clashes w/ 1.2b9-dev spotted by Dean Gaudet

reworked callback mechanism a bit:
- folded duplicate code in run_stacked_handlers() + perl_call()
- gv_fetchmethod called only if -DPERL_METHOD_HANDLERS
- perl_handler_ismethod now() uses class stash in gv_fetchmethod
- cache CV from perl_get_cv lookup if -DPERL_STACKED_HANDLERS
- included patch from Eric Bartley so we can say:
  `Class->method' in Perl*Handler's if -DPERL_METHOD_HANDLERS
- fixed bug spotted by Rob Hartill so Perl*Handler (OK|DECLINED) work again
- added minimal tests for stacked handlers and method handlers
- PERL_METHOD_HANDLERS=1 can be set when running Makefile.PL

PerlCleanupHandler now uses register_cleanup underneath, 
instead of abusing the logger slot. 
PerlCleanupHandler is enabled by default

added PRINTF for tie'd STDOUT

detached Apache.o from httpd, now a dynamic extension. here's why:
- shinks httpd size 
- possible to 'use Apache ()' outside of httpd 
  (very few methods will work though!)
- once mod_perl.c settles it will be possible to upgrade mod_perl 
  without rebuilding httpd!

added $r->server_root_relative function

Apache::Status has 2 new menu items (need Devel::Symdump 1.99_01+):
 - "Inheritance Tree"
 - "ISA Tree" 

added new CGI.pm tests from Andreas

=item 0.97 - 04/15/97

don't add mod_perl/x.xx to Server: unless 'perl Makefile.PL ADD_VERSION=1'

ability to set $r->args, $r->connection->user and $r->connection->auth_type

applied patch from Dean Gaudet so $r->exit uses log_transaction 
instead of multi_log_transaction

=item 0.95_06

fixed typo in new merge function that broke PerlHeaderParserHandler

=item 0.95_05

make sure merge of configs accounts for sendheader and setup_env too!

applied patches from Glen McCallum <glenm@tusc.com.au> so build works
with hpux 10.20's native compiler

=item 0.95_04

dir configs are now merged so <Location> blocks can have Perl*Handlers
and PerSetVar's without stomping those that are in .htaccess

Apache->seqno will use the scoreboard's my_access_count if the -DSTATUS
option is enabled (default if mod_status is configured in)

=item 0.95_03

with 1.2b8-dev+, we no longer need a Makefile.tmpl

added Apache->max_requests_per_child method

now have taint.t test

added <Perl> config section (see httpd.conf.pl)
(needs 'perl Makefile.PL PERL_SECTIONS=1')

Apache::Registry will now chdir to directory where the script

Apache::AuthenDBI and Apache::Authen removed from distribution,
now maintained by John Groenveld and Steve Kane

added PerlInitHandler and PerlCleanupHandler hooks 

Apache::Registry will require CGI.pm version 2.32 or higher if it
finds CGI.pm in %INC

added Apache::Registry->push_cleanup method suggested by Frank Cringle.

applied patches from Gerald Richter <richter@ecos.de> to:
-fix Apache::unescape_url_info
-one s/Apache::Config/Apache::MyConfig/ in Makefile.PL

=item 0.95_02

introduced experimental "stacked handlers" mechanism, allowing more
than one Perl*Handler to be defined and run during each stage of the
request.  

Perl*Handler directives can now define any number of subroutines, e.g.
 
 PerlTransHandler OneTrans TwoTrans RedTrans BlueTrans

with a new method, Apache->push_handlers can add to the stack by
scripts at runtime

PerlLogHandler enabled by default during "stacked handlers" experiment

applied patches from Andreas to quiet prototype warnings seen with
perl5.003_94  

applied patches from Gerald Richter <richter@ecos.de> to:

*** CGI-XA/* removed from distribution ***
CGI.pm-2.32 is now mod_perl compatible, and 
now ships with CGI::Switch and CGI::Apache. 
******************************************

various documentation updates

renamed Apache::CGI to CGI::Apache 
(you should be using CGI::Switch anyhow!!!)

Perl*Handler package names no longer require a '::' to default
to PackageName::handler() when Perl*Handler is just PackageName

renamed eg/MyPackage.pl to startup.pl, pruned way down to
discourage use of PerlScript and avoid the confusion it has caused in
the past 

updated Makefile.tmpl-1.2 to work with 1.2b8-dev, there will be
a "Multiple rules lines" warning, once 1.2b8 is released, we'll 
take this out

added $r->prev and $r->next methods 

added Apache->taint method

Apache->untaint method now in Apache.xs

added $r->seqno method suggested by Lincoln Stein

added GETC and READLINE for tie *STDIN completeness

fixed Apache::CGI+file upload w/ patch from Andreas

data read from client ($r->read*, $r->args), %ENV, $r->cgi_env and
$r->*header*_* is now marked as tainted, t/net/test now tests this
(only with with `PerlTaintCheck On' of course)

various cleanup, including shifting things so Apache.o can be detached
from httpd to Apache.sl if the need arises 

now -Wall clean, except for Perl's dXSUB_SYS->dummy

set $|=1 by default #ifdef USE_SFIO

added Apache->module method

added Apache::Status->menu_item method

fixed warnings in Apache->read spotted by Owen Scott Medd

applied Apache::Registry fixes from Andreas

removed pp_hot.patch from distibution

t/net/http-post.t will now test the tie'd *STDIN if $] >= 5.003_93

*STDIN is now tie'd to the client, only works if perl version is
>= 5.003_93 

removed Apache::TieHandle from the distribution as it is no longer
needed.  however, scripts that are currently using:
use Apache:TieHandle ();
tie *STDOUT => "Apache::TieHandle";
will not break, but will produce a no longer needed warning

removed Apache::Registry's attempt to honor __END__, as Andreas
pointed out, this can't really be done right unless we have
Perl::Lex and Perl::Parse :-)

applied Makefile.PL patch from Andreas to use modules instead of
system() where possible

Apache::Constants now defines SERVER_SUBVERSION,
as suggested by Andreas

removed is_perlaliased from Apache::Debug, caught by Andreas

=item 0.93_01 - 03/04/97

added 'use ExtUtils::testlib' to t/docs/startup.pl since PERL5LIB
is shutoff with -T!?!

picky compilers should no longer complain of things reported
by Mike Stok and George Hartlieb when sfio is configured in

added (temporary?) `PerlWarn' directive to pass the -w switch
to perl_parse

bug fix so stderr is hooked to the error_log as it was and
should be (unless PERL_TRACE is defined)

argv[0] to perl_parse is now "httpd", making the value of 
magic $^X "httpd"

`PerlSetupEnv' now on by default

Apache::Registry parses command line switches if it sees #!, 
only -w and -T are recognized at the moment (not enough!)

Apache::Registry now honors __END__

(I needed this for -DHPUX10 + Apache::Constants)  

we now define SERVER_SUBVERSION as suggested by Andreas

fixed $$ bug in CGI::XA with fix from Salvador Garcia

added $r->is_initial_req method, now used by these modules:
Apache::AuthenDBI, Apache::AccessLimitNum, Apache::AuthzAge

Apache::warn now overrides CORE::warn in Apache::Registry scripts,
which is an alias for Apache::log_error 

Apache::exit now overrides CORE::exit in Apache::Registry scripts,
now converted CGI scripts can safely call plain 'ol exit;

$r->exit will close the client connection for you, no need for
$r->connection->close, which is no longer documented, and does 
nothing but warn not to call it.

fixed cookie bugs in CGI::XA spotted by Andrew Tennant

#undef some symbols that caused clashes #ifdef HPUX10
and ones on solaris spotted by Bowen Dwelle

fixed core-dump-causing bug spotted by Mike Stok

=item 0.91 - 01/22/97

perl_init now says 'use Apache::Constants qw(OK DECLINED)' (in C) so you can

applied patch from Rob so Makefile.PL copies $APACHE_SRC/Configuration to src/
if it has been changed

added Makefile.tmpl-1.2b5 from Rob

applied patch from Rob Hartill to stop $r->cgi_env($key) from core-dumping 
if $key does not exist

applied PerlModule overflow check patch from Rob Hartill

added $r->as_string method

=item 0.90_01

depreciation of Apache->request use outside of Apache::CGI and scripts
that run under Apache::Registry now spits out a warning.  See Apache.pm
doc update for details.

$r->is_perlaliased has gone away

added api tests

added tests for callback hooks besides PerlHandler

added Apache::perl_hook function

if a callback does not return a status values, we assume OK, 
fatal errors would have never made it that far anyhow, 
still log warning to error_log, but carry on

clean up here and there

added PerlHeaderParserHandler callback hook for apache versions >= 1.2b5

added $r->connection->aborted method
added $r->the_request and $r->header_only methods
added Apache::Server methods: is_virtual and names

added $r->headers_out and $r->err_header_out methods:
header*_* methods are now consistent, see Apache.pm docs

should now use $r->err_header_out instead of $r->err_headers_out
to set the value of an err_header

added 1.1.3 to Makefile.PL version map after hint from Arin Goldberg

src/modules/perl/Makefile now detects modules linked static with
your perl and links them with httpd

suggested by Rob Hartill

Makefile.PL now copies $APACHE_SRC/Configuration to src/ modifies, 
then tells apache's Configure to use this copy with -file

applied patch from Pai-Ling Hsiao <pailing@STRAWBERRY.UCC.UCONN.EDU>
o fix CGI::XA->*_group bugs

t/constants/export.t now tests _all_ of @EXPORT and %EXPORT_TAGS

fixed bugs in Apache::Constants spotted by John Groenveld and Rob Hartill

Apache.xs now uses rwrite() if apache >= 1.2b4

=item 0.90

perl Makefile.PL PERL_TRACE=1 will now enable tracing

  perl Makefile.PL PERL_AUTHEN=1 PERL_FIXUP=1

updated INSTALL and mod_perl.pod to reflect this change

=item 0.89

fixed bug spotted by Rob Hartill so perl_cmds[] is not prematurely
terminated

added Bundle::Apache module for use with CPAN.pm

fixed Constants/Makefile.PL so -I picks up $(APACHE_SRC) no matter what,
thanks to Mike Stok

=item 0.88

applied Makefile.PL patch from Rob Hartill so we compile with 1.2b3

=item 0.87

As suggested by Andreas, Makefile.PL now asks:
"Configure mod_perl with ../apache_xxx ?"
  answering 'y' only means there is where we can find *.h
"Shall I build httpd in $adir for you?"
  answering 'y' will run ../apache_xxx/Configure 
  and httpd will be built when running 'make'
 
$r->read now returns $nrd as it should

'perl Makefile.PL NO_HTTPD=1' will build only the perl side of
mod_perl (still need httpd.h for Constants.sl)

'make test' now picks up modules in ./blib as it should, bug
spotted by Mike Stok
 
ServerName is set to localhost in httpd.conf as suggested by 
Mike Stok and Frank Cringle

=item 0.86

Port is a little more random for tests '8529'

applied patch from Edmund Mergl <E.Mergl@BAWUE.DE> bringing CGI::XA 
up-to-date with CGI.pm 2.29

perl_destruct_level is set to 0 in mod_perl.c, while progress is being
made on fixing perl_{con,des}truct in 5.003_12

if there is no httpd.conf, Makefile.PL creates one for you, filling in
User and Group with uid and gid of the current process

updated Makefile.tmpl-1.2 with Makefile.tmpl from apache 1.2b2

if Makefile.PL finds apache version >= 1.2b3, instead of copying
Makefile.tmpl to ../src/apache_x.x, it uses the new '-make Makefile.tmpl'
option, made possible by Rob Hartill
otherwise, same as before and it now tells you it's made a backup 
'Makefile.tmpl.bak'

fixed 'make test', so you _really_ don't have to modify anything,
hopefully

if libwww-perl is not installed, the tests that require it will not be run,
and it will be suggested that you install the library, but who doesn't
have libwww-perl installed???

=item 0.85_06

same as 0.85_05, just fixed broken tarball

build Perl, thanks to Andreas

added 'make offsite-tar' target for build the perl-side on machines 
without apache source

fixed Makefile.tmpl* so people define EXTRA_FLAGS as suggested by Rob Hartill

a few minor fixes for Apache-SSL users

=item 0.85_04

applied patch from Rob Hartill to fix bug in $r->cgi_env

%ENV is cleared after each callback (&Perl*Handler)

added $r->cgi_var as suggested by Andreas:
calls $r->cgi_env($key) in a scalar context to prevent the 
mistake of calling in a list context.

if a Perl*Handler returns something > 600 we assume OK (for now)

bug fixed introduced in 0.85_03 for Perl*Handler's not prefixed with 
a Package:: causing httpd to sigsegv

ship with Makefile.tmpl-Ben-SSL for Apache-SSL users

Makefile.PL a little smarter
-knows if we're configuring with Ben-SSL, uses Makefile.tmpl-Ben-SSL
-after looking for 1.1.1 and 1.2*, globs for <apache*> not <apache_*>
-instead of rm -rf'ing the modules/perl/ directory we're configuring
 against, we only rm -f those found in our MANIFEST

applied patch from Frank Cringle <fdc@CLIWE.PING.DE> to fix defaults
in CGI::XA

got rid of stupid warning "missing test.pl"

=item 0.85_03

cleaned up internal perl_setup_env()

Perl*Handler's default to calling Perl*Handler::handler if the
Perl*Handler is just a class name, e.g. 'PerlHandler Apache::Registry'
will call Apache::Registry::handler
In addition, the class module will be loaded if it is not already, 
so there is no need to specify PerlModule

added Apache::Status module 

$r->print now sets a hard_timeout() before sending to the client
$r->read now sets a hard_timeout() before reading from the client

added $r->soft_timeout, $r->hard_timeout, $r->kill_timeout and
$r->reset_timeout methods

top-level Makefile.PL looks further for apache_x.x/src/ 
prompts you if nothing found

applied fix from Andreas to s/privlib/privlibexp/ in src/modules/perl/Makefile

applied patch from Rob Hartill <robh@imdb.com> to correctly initialize
cld->sendheader and cld->setup_env

=item 0.85_02

Apache::DBIAuthen renamed Apache::AuthenDBI and split out from
Apache::Authen

Apache::Authen->handler renamed Apache::Authen->check
as it is not a handler, only used by handlers

added ToDo file

updated UserGuide, now called 'mod_perl.pod'

updated INSTALL and README docs

perl_init will only perl_alloc and perl_contstruct once when the server
starts, meaning no more mad leaks when server is restarted

modified test suite adding extra tests for sfio and TIEHANDLE

unless Perl was configured to use perlio and sfio, STDOUT is tied by default to
the client, no more need for tie *STDOUT => Apache::TieHandle

Makefile.PL now looks for ../apache_1.1.1/src/, apache_1.2*/src/ to configure 
against

Fixed Makefile.PL bug spotted by Frank Cringle <fdc@CLIWE.PING.DE>, 
when no apache source was present or chosen to configure against

'make clean' will now cd $(APACHE_SRC) && $(MAKE) clean

applied patch from Rob Hartill <robh@imdb.com> to bring us up-to-date
with apache_1.2b0

$r->content now calls $r->read instead of $r->read_client_block

$r->read is no longer an alias for $r->read_client_block
The new $r->read implementation is based on patches and ideas from 
Milan Votava <ms.anet.cz@MS.ANET.CZ>,
Joonsuk Bae <bae@yahoo.com>,
and Gisle

=item 0.85_01

added 'tar_Apache' target for copying the perl-side of mod_perl to other 
machines without dragging the apache-side along.

'perl Makefile.PL' now Configures Apache to link mod_perl 
if ../apache_1.2-dev or ../apache_1.1.1  src/Configuration is found
In addition, 'apache_httpd' is added to the 'make all' target 

now include Makefile.tmpl-1.2

fix for 1.2's const requirement

=item 0.85

added the start of a mod_perl test suite

got rid of conditional perl*rec members, which was causing compile problems
for some people

send_cgi_header now sets $r->status to REDIRECT when it finds a Location
header which is not an internal redirect

Apache::Registry now returns $r->status rather than always OK

dropped old approach of the original mod_perl.c, mod_perl_fast functionality
has moved to the all-knowing, all-doing mod_perl

Makefile.PL for Apache::Constants looks for httpd.h in ../../apache*/src/ 
before prompting

dropped OK from @{$Apache::Constants::EXPORT_TAGS{response_codes}}

applied Makefile.PL patch from Gisle to set PERL= in Makefile*

=item 0.83_09

fixed bug with get_basic_auth_pw spotted by Patrick Kane <modus@enews.com>

=item 0.83_08

get_basic_auth_pw now returns the $send_pw, rather that setting it,
see Apache.pm docs
 
applied patch from Andreas with the following changes:

1) regex directory added in Constants/Makefile.PL. Current apache
   always needs -Iregex, that means for us an additional
   -I$httpd/regex. I think, they should

    #include <regex/something.h>

2) Assorted comments added to INSTALL, especially

  * FileHandle bug explained as being a 5.003 bug (not "current")

  * Configuration/Configuration.tmpl relation explained

  * && instead of ; to separate commands is a must in Makefiles

  * Gisle's hint about the default seems very important to me, so is
    there again.

3) Drops the deprecated mod_alias patch from the whole distribution

4) A whitespace patch for src/modules/perl/Makefile

5) The regex directory also for src/modules/perl/Makefile

6) Shuffling of code between mod_perl_fast.c and mod_perl.h until it
   fits the bill, who knows why :-0

added callback hooks for authorization, access, type-check, 
fixup and logger stages of the request

callback hooks can now be turned off at compile time with 
-DNO_PERL_...., and are turned off by default, except for the
handler stage (PerlHandler) 

reworked installation procedure to follow apache 1.2 recomendations, 
the procedure will still work with older versions of apache.
No more Makefile.tmpl.x.x.x mess!!

updated #if MODULE_MAGIC_NUMBERS >='s so we're inline with apache 1.2-dev-19961009130008

=item 0.83_03

Perl*Handler's are now called with Apache->request as an argument
PerlHandler's may still ask for Apache->request so existing code and
mechanisms such as Apache::Registry will continue to work
However, other handlers such as PerlAuthenHandler and PerlTransHandler,
cannot use Apache->request.

added Apache::Constants module, based on patch to Apache.xs 
from Gisle

updated Apache::Debug with patch from Gisle to 
- update the status codes from the latest
  HTTP::Status and produce a prettier and more output.

added method 'request' to return the request pointer object
And did a typedef request_rec * Apache
