The session extension has a --with-mm flag that tells it to build
the mm backend ("mm" is the name of the library). However, that
backend is not thread-safe, and mod_mm.c will refuse to compile if
the --enable-maintainer-zts flag was also passed to the configure
script.
Rather than crash halfway through the build, this commit adds a check
to the session extension's config.m4 file. If both --with-mm and
--enable-maintainer-zts are "on," then the configure script will
die and explain that they can't be used together.
PHP-bug: 14269
The bug causes the kernel not to return -1/EAGAIN. The new test case
has been borrowed from the Linux Test Project.
This also fixes a bug which apparently caused HAVE_PREAD/WRITE to be
defined even if the more complex checks failed (ac_cv_func_NAME=no
was set albeit with no difference).
The old checks supposed that pread/pwrite worked, if a declaration was
found in <unistd.h>. We now actually check whether they work successfully
before using them.
The following new/revived shared modules are available now:
... MySQL (*)
... PCRE (*)
... Session
... SWF
(*) capable of using bundled library or external library
All changes:
The m4 macro PHP_EXTENSION was revamped. Uses LIB_BUILD now.
This effectively means that all extensions have to use dynlib.
ext/mysql/config.m4 was revamped.
Uses LIB_BUILD for building bundled library.
ext/pcre/config.m4 was revamped.
Uses LIB_BUILD for building bundled library.
ext/ext_skel was changed to reflect that more modules should be
compileable as shared module.
ext/Makefile.in has been simplified enormously.
Dependencies are now stored in the build tree.
Empty dependencies are not generated by buildconf anymore. They
are now dynamically created during the build process.
Implicit rules for .S were removed.
The NO_RECURSION feature was removed.
"libs.mk" has been added to all cvsignore files in ext.
- 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.
this uses a custom scanner which detects relative URIs and changes
them appropiately.
must be explicitly enabled with --enable-trans-sid
(normal case is not affected, since session_adapt_uris defaults to
void statement. Compiler should eliminate dead code in output.c then.)
- improve genif.sh to also consider all header files for inclusion
(checks for phpext_)
- use vsnprintf in main.c to avoid buffer overflows
- improve sessions's mm module to cope better with OOM situations
within the shared memory segment
- fix typo wrt session.auto_start
- fix gc probability algorithm
- don't access mod_data directly
- initial version of mm support for session data storage
This works pretty good, but we need to create the initial mm pool
from the parent process/thread. Still looking for a clean way to do that.
