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.

The macro checks for existence of size_t in <stddef.h> otherwise it sets
it to 'unsigned int'. The size_t is part of C89 standard and all
platforms should have it. Macro is also marked to be made obsolete in
the future versions of Autoconf.
At this point there is still AC_FUNC_ALLOCA in PHP's configure.ac which
uses AC_TYPE_SIZE_T under the hood so the check is still done there in
the meantime.
- AC_CHECK_HEADERS already includes the header(s) listed in the first
argument, so additional net/if.h is redundant.
- The crypt.h is checked two times and HAVE_CRYPT_H is only needed in
ext/standard.
- Remove duplicate <string.h> in ext/standard
- Remove duplicate <string.h> in getaddrinfo check in configure.ac
- Unused header checks removed:
HAVE_NETINET_TCP_H and HAVE_SYS_UN_H are not used in the code.
- Duplicate linux/filter.h check removed:
HAVE_LINUX_FILTER_H is already defined in ext/sockets.
clang and newer gcc releases support byte-sized atomic accesses on
riscv64 through inline builtins. In both cases the hard dependency on
libatomic added by GH-11321 isn't useful.
Stop using AC_CHECK_LIB() which is too naive to notice that libatomic
isn't needed. Instead, PHP_CHECK_FUNC() will retry the check with -latomic
if required.
Closes GH-11790
This moves the fiber configure option in the Zend section. TSRM doesn't
currently have any specific configure options so it can be removed from
the ./configure --help output.
When building from sources, someone distributing PHP may want to add a
vendor specific string to the PHP_VERSION so users can differentiate
multiple vendor builds from the same PHP version. For instance, a vendor
backporting a bug fix to a no-longer-supported PHP version could extend
their PHP_EXTRA_VERSION to allow their users to identify that they carry
such fix by checking their PHP_VERSION.
Closes GH-11706
The two unsets before the last `unset LIBS LDFLAGS` are not necessary so
LDFLAGS can be adjusted via command line:

`zend_rc_debug` is not a type and does not really belong in
`zend_types.h`; this allows using `ZEND_RC_MOD_CHECK()` without
including the huge `zend_types.h` header and allows decoupling
circular header dependencies.
1. Implementation based on https://github.com/WojciechMula/base64simd
2. Only runtime path is added to reduce the complexity of SIMD variants.
3. Expand test case to cover SIMD implementation.

The release VMs already enforced this, but PHP's configure script did
not.
re2c 0.13.5, which timelib's date/time parser requires is no longer
compatible with the current version of Zend/zend_language_scanner.l, as
it starts spinning in a loop.
As with other SIMD-accelerated functions in php-src, the new UTF-16
encoding and decoding routines can be compiled either with AVX2
acceleration "always on", "always off", or else with runtime detection
of AVX2 support.
With the new UTF-16 decoder/encoder, conversion of extremely short
strings (as in several bytes) has the same performance as before,
and conversion of medium-length (~100 character) strings is about 65%
faster, but conversion of long (~10,000 character) strings is around
6 times faster.
Many other mbstring functions will also be faster now when handling
UTF-16; for example, mb_strlen is almost 3 times faster on medium
strings, and almost 9 times faster on long strings. (Why does mb_strlen
benefit more from AVX2 acceleration than mb_convert_encoding? It's
because mb_strlen only needs to decode, but not re-encode, the input
string, and the UTF-16 decoder benefits much more from SIMD
acceleration than the UTF-16 encoder.)
To make sure that compiler supports C99 before Autoconf 2.69, this was
needed. But with Autoconf 2.70 and later the macro is obsolete because
the checks are done in AC_PROG_CC and warnings are emitted when building
configure script.
