C++11 puts isfinite, isinf, isnan and a lot of other stuff into the
std namespace. Thus, if a C++11 or newer source is compiled, these
symbols won't be available. A good solution would be to include cmath,
but depending on a particular compiler that might remove even more
stuff from the global namespace, so such a fix should only target master.
For now, just keep these defines same for C++11 and upper, as the actual
C++ code should use symbols from the std namespace anyway. This
especially concerns older GCC versions like at least 4 and 5, which are
used by default in the LTS Linux distros.
Since PHP 7.2 the minimum autoconf version is 2.64. The configure.ac
script file includes also AX_CHECK_COMPILE_FLAG macro call so besides
only checking it in buildconf script this bumps the autoconf here too.
The phpize.m4 script is for now still relaxed to 2.59 version since some
still supported systems such as CentOS 6 still include autoconf 2.63
version and might require calling phpize on some old extensions.
Autoconf doesn't mention the AC_CONFIG_HEADER macro since the v2.13
released in 1999 anywhere in the documentation. Future of this macro is
unclear and commented as possible candidate for obsoletion in the
autoconf source code. Since it is just a wrapper around the main
AC_CONFIG_HEADERS macro, the functionality is the same, and also more
clear to find it in the autoconf documentation and avoid possible future
obsoletion.
The IPv6 IP of a socket is provided by inet_ntop() as a string, but
this function doesn't enclose the IP in brackets. This patch adds
them in the php_network_populate_name_from_sockaddr() function.
On systems without glibc, such as Alpine with Musl libc, the function attributes
are not supported. GCC 6 doesn't properly omit some systems. This is
already fixed in GCC 7 but for systems with GCC 6 and ones without
glibc, this additional check fixes this bug.
Named subpatterns are now passed to `mb_ereg_replace_callback`.
This commit also adds a subset of the oniguruma back-reference syntax
for replacements:
* `\k<name>` and `\k'name'` for named subpatterns.
* `\k<n>` and `\k'n'` for numbered subpatterns
These last two notations allow referencing numbered groups where n > 9.
`mb_ereg`, `mb_ereg_search_regs` & `mb_ereg_search_getregs`
returned only numbered capturing groups.
Now they return both numbered and named capturing groups.
Fixes Bug #72704.
Test case: strnatcmp_ex(L"333", 3, L"333 ", 4, true)
The reason this bug didn't come up earlier is probably because most input strings are null-terminated.
