- 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)
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().
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.
