`socket_bind()` may raise `E_WARNING` on failure, which would cause the
test to be marked as borked. Since we're checking the return value
anyway, we can silence warnings.
As of PHP 8.0.0, failing `zend_fetch_resource_ex()` throws a TypeError,
so we cannot simply skip non resources in the `$read`, `$write` and
`$except` arrays. Instead we bail out. Since these arrays are already
checked in `php_sock_array_to_fd_set()`, we remove the additional check
in `php_sock_array_from_fd_set()`.
If interface 'lo' is not available, `socket_set_option()` may warn,
which would cause the test to be marked as borked. Thus we silence the
function call.
The AI_IDN_ALLOW_UNASSIGNED and AI_IDN_USE_STD3_ASCII_RULES have
been deprecated by glibcs, and PHP 7.4 follows this deprecation.
This removes the offending flags for PHP 8.0.
These flags have been deprecated in glibc 2.28, so we also
deprecate them in PHP.
As we can't deprecate constants, we can only check for their use
in socket_addrinfo_lookup().
The result of this check is to whether to define the HAVE_CMSGHDR symbol
or not. The HAVE_CMSGHDR is never used in the code and it has been
removed via 90289924c0.
Closes GH-4337
Removed unused checks:
- mbsinit check removed, HAVE_MBSINIT removed (not used in php-src)
- mempcpy check removed, HAVE_MEMPCPY removed (not used in php-src anymore since
560ed89bfb which uses PHP's own implementation)
- strpncpy check removed, added via a8c9e893b6 and
not used.
- setpgid check removed since HAVE_SETPGID is not used
Moved to a central configure.ac:
- fpclass
- mbrlen moved to configure.ac (since the HAVE_MBRLEN is used accross the php-src)
- sigprocmask
- getcwd
- getwd
- glob
- strfmon
- nice
Duplicated checks removed:
- gethostname
- getlogin
- getpwuid_r
- socketpair
- mprotect check simplified
Some headers were checked multiple times in the main configure.ac file
and in the bundled extensions or SAPIs themselves. Also many of these
checks are then used accross other extensions or SAPIs so a central
configure.ac makes most sense for these checks.
