The m4_normalize([$1]) normalizes items into a single-space-separated
list of files to append them to the global PHP_OUTPUT_FILES variable
that is processed by AC_CONFIG_FILES. Redundant newlines are also
removed in the generated configure script.
PHP extensions using phpize can't use this macro so it's safe to change
this.
This macro once had also the 5th argument (the build target), which was
removed via 2a6da0f24c. This quotes all
PHP_SELECT_SAPI arguments and removes the redundant ones. The basic
macro usage help text is moved to the macros section from the obsolete
docs file.
This appends the possible rt library as needed on Solaris <= 10 to
FPM_EXTRA_LIBS instead of the global LIBS variable for all SAPIs to have
cleaner build. The possible required rt library for other SAPIs is also
checked in the configure.ac.
Instead of appending -lselinux to global LIBS variable, this adds it as
needed only to FPM_EXTRA_LIBS as it was already used in the BUILD_FPM
invocation.
Follow-up of GH-14881
Instead of appending -lapparmor to global LIBS variable, this adds it as
needed only to FPM_EXTRA_LIBS as it was already used in the BUILD_FPM
invocation.
Follow-up of GH-14881
Instead of appending -lsystemd to global LIBS variable, this adds it as
needed only to FPM_EXTRA_LIBS as it was already used in the BUILD_FPM
invocation. Move php_fpm_systemd substitution after its check.
Follow-up of GH-14881
- This syncs CS and wraps ptrace function check in a single
AC_CACHE_CHECK for optional edge case cross-compiling adjustments
- Overquoted arguments are reduced (first the compilation check if
ptrace in proper form is available on the system and then the run
check if ptrace works as expected)
- The cache variable php_cv_have_mach_vm_read is renamed to
php_cv_func_mach_vm_read.
- ACL user/group check wrapped in AC_CACHE_CHECK
- instead of appending -lacl to global LIBS variable, this adds it as
needed only to FPM_EXTRA_LIBS as it was already used in the BUILD_FPM
invocation
This removes obsolete link to php-fpm.org and redundant manual link in
favor of a dedicated FPM chapters.
Can be tested with:
man sapi/fpm/php-fpm.8.in
- Arguments quoted
- Redundant comments removed (some basic help info is in the
build/php.m4)
- APXS variable as such isn't used in the generated Makefile, the path
to the apxs tool is inserted during the configure step directly
- This simplifies over-quoted arguments to AC_COMPILE_IFELSE
- Indentation and other CS fixes
- php_cv_* cache variables
- AC_DEFINE help texts syncs to make it more clear
- Fix -Wunused-but-set-variable warnings
The ping feature of php-fpm monitoring was previously not working
in pm.status_listen pool due to the configuration variables ping.path
and ping.response not being copied over to the worker when forked. This
results in the ping code path being disabled because the worker detects
that ping.path is not configured.

* Mark many functions as static
Multiple functions are missing the static qualifier.
* remove unused struct sigactions
struct sigaction act, old_term, old_quit, old_int;
all unused.
* optimizer: minXOR and maxXOR are unused
This reduces -Wunused-variable and -Wunused-but-set-variable warnings
generated in the Autoconf's config.log to comply with possible stricter
default compiler configuration on the system to avoid having false
results.
The PHP_SUBST_OLD adds variables to generated Makefile and creates
output shell variables to replace the @variable_name@ placeholders in
templates. These changed variables are not used in the generated
Makefile so the AC_SUBST is sufficient.
- ext/odbc
- sapi/embed
- sapi/fpm
- only substituted in scripts/php-config.in:
- PHP_INSTALLED_SAPIS
- SAPI_LIBNAME_SHARED
- SAPI_LIBNAME_STATIC
`if (fpm_shm_size - size > 0)` will be rewritten by the compiler as this: `if (fpm_shm_size != size)`, which is undesirable. The reason this happens is that both variables are size_t, so subtracting them cannot be negative. The only way it can be not > 0, is if they're equal because the result will then be 0. This means that the else branch won't work properly. E.g. if `fpm_shm_size == 50` and `size == 51`, then `fpm_shm_size` will wraparound instead of becoming zero.
To showcase that the compiler actually does this, take a look at this
isolated case: https://godbolt.org/z/azobdWcrY. Here we can see the
usage of the compare instruction + cmove, so the "then" branch
is only done if the variables are equal.
autoconf/libtool generating code to test features missed `void` for
C calls prototypes w/o arguments.
Note that specific changes related to libtool have to be upstreamed.

The SELinux library has had pkg-config/pkgconf integration since ~2009.
To ease this change, the check without pkgconf is executed in case the
libselinux.pc file is not found on the system.
A sanity check also covers cases where the library path is overriden:
/configure --enable-fpm --with-fpm-selinux \
SELINUX_CFLAGS=-I/path/to/libselinux \
SELINUX_LIBS="-L/path/to/libselinux -lselinux"
This also removes the redundant symbol HAVE_SELINUX_SELINUX_H since the
selinux/selinux.h header is considered a required part of the SELinux
library package.
