- Make sapi_module available to external modules (PHPAPI)
- Make the php.ini path reported in phpinfo() always point to
real full path of the php.ini file
- Optimized the ISAPI module not to read unnecessary server
variables and read necessary variables at most once.
SAPI and down into the individual SAPI modules. I have made the
appropriate changes in all the SAPI modules, but please verify these.
The reason for this change is that Apache sometimes will feed PHP
a request_method of GET but have r->header_only set to true. This happens
in an ErrorDocument redirect. In this same scenario we want to preserve
the status code as well instead of just overwriting it with a 200 and
losing this information. For now the other sapi modules act exactly as
before since they probably do not make this distinction, and they may
not even have a valid response code this early in the request.
@ Fix HEAD request bug on an Apache ErrorDocument redirect and preserve
@ the status code across the redirect as well. (Rasmus)
* Makefile header is now completely dynamic
* Absolute paths in (top_)?(src|build)dir and VPATH
(fixes Tru64 support)
* VPATH does not contain variables anymore
(fixes UnixWare support)
- Added $HTTP_ENV_VARS[] and $HTTP_SERVER_VARS[] support, which similarly
to $HTTP_GET_VARS[], contain environment and server variables. Setting
register_globals to Off will now also prevent registration of the
environment and server variables into the global scope (Zeev)
- Renamed gpc_globals to register_globals (Zeev)
- Introduced variables_order that deprecates gpc_order, and allows control
over the server and environment variables, in addition to GET/POST/Cookies
(Zeev)
- Got rid of the old flush() implemenetation in favour of the new one
- Added implicit_flush() support to the output buffering layer.
@- Added implicit_flush() to control whether flush() should be called
@ implicitly after any output (Zeev)
- added support for externally built modules,
- improved support for in-tree shared modules,
- fixed diversion bugs,
- configure displays some informative messages,
- faster static build
(libtool isn't used anymore for compiling non-PIC objects),
- dependencies comparable to automake's without requiring GNU make or GCC,
- working make clean for non-GNU makes.
These cannot be implemented platform-independent, so we fall back to the native
non-reentrant versions, but lock during each access (only if ZTS is used).
To initialize/destroy the used data structures, you need to call
reentrancy_startup() before sapi_startup(), and reentrancy_shutdown() after
sapi_shutdown().
necessary, because we can change the value of INCLUDES globally in one
place (configure.in).
Also add two defines in thread-safe mode
(_REENTRANT and POSIX_PTHREAD_SEMANTICS)
with libtool components
* SAPI targets can enable thread-safe mode and define
shared/static/program build target
* all configure scripts use the same config.cache
* phplibdir is $(top_builddir)/modules to avoid
permission problems
* sapi/*/Makefile.inc are gone
* runpath handling cleaned up
* top-level Makefile.in obsoleted through Makefile.am
* --enable-versioning uses libtool's cleaner and more
portable -export-symbols feature
implementation now has its own directory under sapi/, just like
extensions have theirs under ext/. To make the final targets appear
in the main dir, the top-level Makefile includes sapi/NN/Makefile.inc
from the selected sapi backend. This is a plan Makefile stub without
any autoconf substitutions. Each SAPI backend also has its own
config.m4 like extensions (read at the end of diversion 2) and
config.h.stub files.
Each SAPI backend has to contain:
config.m4: just like for extensions, this file contains
autoconf/automake directives that end up in the configure script. The
only difference is that the sapi config.m4 files are read in diversion
(output block) 2 instead of 3. The sapi config.m4 files should set
two variables: PHP_SAPI (which sapi backend to choose) and SAPI_TARGET
(the name of the resulting library or program, previously BINNAME).
If they are not specified, they will default to "cgi" and "php",
respectively.
Makefile.inc: has to exist, has to define "INSTALL_IT" to the command
used to install the final target (or ":" for no operation). It also
has to define a plain Makefile rule (without autoconf substitutions)
to build $(SAPI_TARGET)
Makefile.am: just what you think. Make sure your target is called
"libphpsapi_NNN.a", where NNN is the value of PHP_SAPI.
Some testing and fixing probably remains. To make everything hang
together, I've done some ugly tricks that I can imagine causing some
problems. I've built and run the CGI version and built the Apache
DSO.
