The non-standard major(), minor(), and makedev() can be defined as
macros. These are usually used together with the Autoconf macro
AC_HEADER_MAJOR, which defines the MAJOR_IN_MKDEV if sys/mkdev.h is
available, or MAJOR_IN_SYSMACROS if sys/sysmacros.h is available.
On Solaris/illumos they are in the sys/mkdev.h header (macro defined to
libc implementation) and in sys/sysmacros.h (macro defined with binary
operators and bits shifting). On systems with musl and glibc 2.28 or
later they are defined in sys/sysmacros.h, in glibc 2.27 and earlier
they were in sys/types.h. On BSD-based systems and macOS they are in the
sys/types.h.
Autoconf 2.70 has fixed the AC_HEADER_MAJOR macro, so it detects the
headers properly due to glibc 2.25 throwing deprecation warnings when
using the macros from sys/types.h. With Autoconf 2.69 and earlier the
ac_cv_header_sys_types_h_makedev cache variable can skip the
improper sys/types.h check in the macro.
This change syncs the usage within the ext/fileinfo/libmagic bundled
library and ext/posix.
When sys/mkdev.h header is available, code includes that, otherwise
it conditionally includes the sys/sysmacros.h. The ext/posix has
additional check whether linker sees the makedev, otherwise it checks
if makedev is declared within the given set of headers accoring to the
AC_HEADER_MAJOR logic. Previously the AC_CHECK_FUNCS didn't detect it.
The '__asm__ goto' support is properly recognized by a simpler linking
check instead of a run check for easier cross-compilation. The
compile only check (AC_COMPILE_IFELSE) might produce false positives
results with certain compiler options.
This was tested on OpenBSD sparc64 and all fiber related tests pass.
On OpenBSD stackghost prevents the modification of the return address
and therefor an extra trampoline is needed in make_fcontext(). This
should not matter on other OS implementing sysv ABI and the trampoline
should work there as well.

Solaris/illumos systems have socket() in the socket library, Haiku has
it in network, Windows in ws2_32, and other systems in libc. This also
removes redundant and unused HAVE_SOCKET symbol.
The memmove() function is C99 standard function [1] and check was left for
the PCRE2 bundled library. It can be simplified by passing the compile
option instead of checking always available function on current systems.
External PCRE2 library on the system doesn't need this.

The htonl() function is available in libc on current *nix systems. On
Solaris versions around 2.5.1 it was located in the socket library.
Haiku has it in libc and Windows in ws2_32, which is linked as part of
the common libraries. This removes the redundant HAVE_HTONL symbol.
This moves memfd_create (HAVE_MEMFD_CREATE) to configure.ac. Since
ext/pcre is always enabled and check can be done in this case for
ext/pcre and ext/opcache at once.
This prepends -lnetwork as needed (Haiku) whether linker sees the
setsockopt function and avoids defining redundant symbols, such as
HAVE_LIBNETWORK and HAVE_SETSOCKOPT.
For Solaris/illumos systems, in this case, the check can be done using
AC_SEARCH_LIBS, which avoids defining redundant symbols like HAVE_PGRAB
and HAVE_LIBPROC.
The nanosleep() is mostly found in libc, except on systems, such as
Solaris <= 10 or the discontinued OpenSolaris, it is in the rt library.
This checks if nanosleep() exists in the libc, then it checks if rt
library has nanosleep, prepends it to LIBS and defines the
HAVE_NANOSLEEP symbol with the template from the AC_CHECK_FUNCS.
On some systems (Haiku) the math library is part of the C library and it
doesn't need to be explicitly prepended to LIBS. The redundant HAVE_LIBM
symbol defined by the AC_CHECK_LIB has been removed.
AC_SEARCH_LIBS can be used to check for dlopen and if dl library needs
to be prepended to LIBS. The dlsym is available with the same scope as
dlopen (if dlopen is present, also dlsym is). The redundant HAVE_DLOPEN
and HAVE_DLSYM symbols have been removed.
The AC_CHECK_FUNCS checks whether the linker sees the function in the
usual libraries, in this case libc. This is a simple trick to also check
existence of belonging headers, since the code uses HAVE_PRCTL and
HAVE_PROCCTL to include headers and call functions.
This removes the redundant check that defines the HAVE_STDINT_H symbol,
which is used in the ext/date/lib and ext/fileinfo/libmagic but on both
places patches and other header files take care of this so it is always
included unconditionally in php-src.
Autoconf by default still automatically checks for stdint.h internally
in current versions, so for now the HAVE_STDINT_H symbol is still
defined in php_config.h and will be made redundant along the way.
This removes the deprecated malloc.h header Autoconf check on *nix
systems and its HAVE_MALLOC_H symbol. It can be replaced mostly with the
stdlib.h. The libgd usptream also doesn't include it anymore.
On Windows, it is still used for some memory allocation functions, but
can be replaced with stdlib.h in the future.
Instead of the project macro, the sockaddr_storage and sockaddr.sa_len
can be checked with the AC_CHECK_TYPES and AC_CHECK_MEMBERS by including
the sys/socket.h. Some systems (~1988) didn't include the sys/types.h in
the socket.h (obsolete on current systems).
These macros by default define the HAVE_STRUCT_SOCKADDR_STORAGE and
HAVE_STRUCT_SOCKADDR_SA_LEN.
The struct flock is defined in fcntl.h, if system has it. This removes
redundant PHP_STRUCT_FLOCK M4 macro in favor of the AC_CHECK_TYPES,
which by default defines symbol HAVE_STRUCT_FLOCK.
PHP_DEFINE was introduced with the PHP 5 build system
9d9d39a0de and then refactored via
350de12bc2.
This was once used to put defined constants into a single file to have
more fine-graned dependencies (atomic includes). Since no known PHP
extension is using this and it makes very little sense to use this, this
M4 macro can be removed in favor of the Autoconf native way using
AC_DEFINE and the usual included files php_config.h and config.h.
- Generated unused include directory removed
- Remove include dir from DEFS
- Remove also include dir from PDO checks
SunOS 4.1.4 from 1994 didn't have fclose declared in standard header
stdio.h. This doesn't need to be checked anymore, as fclose is part of
the C89+ standard and declaration is present on Solaris 10 (SunOS 5.10)
and later.
Global --tag=CC defined in configure.ac is not correct in all cases. For example
linking objects that were compiled from C++ sources needs to be done with C++
compiler, however for link mode libtool will prefer compiler indicated with
--tag.
Fixes GH-12349
The root library was added here for the Haiku system, to check dlopen()
and dlsym(). However, the root library is already explicitly linked in
the system, and it does not need to be checked neither linked anymore,
since at least ~2013.
The fastcgi code was refactored in
18cf4e0a8a and in_addr_t is no longer
used. The PHP_CHECK_IN_ADDR_T is also obsolete and not recommended way
to discover availability of the type. If needed in the future, the
AC_CHECK_TYPES can be used instead.
Autotools emits warning if 3rd argument is empty. Call is wrapped in the
AC_CACHE_CHECK with php_cv_* cache variable name according to the docs.
Closes GH-12966
While __php_mempcpy is only used by ext/standard/crypt_sha*, the
mempcpy "pattern" is used everywhere.
This commit removes __php_mempcpy, adds zend_mempcpy and transforms
open-coded parts into function calls.
This was disabled in 2019 due to problems reported in FreeBSD 11. The original
report (PHP bug 77284) includes a comment that FreeBSD 12 worked - which also
happens to be the first version ifunc use appeared in libc.
