Because the default characters are defined in the stub file, and the
stub file is UTF-8 (typically), the characters are encoded in the string
as UTF-8. When using a different character encoding, there is a mismatch
between what mb_trim expects and the UTF-8 encoded string it gets.
One way of solving this is by making the characters argument nullable,
which would mean that it always uses the internal code path that has the
unicode codepoints that are defaulted actually stored as codepoint
numbers instead of in a string.

`zend_strtod.c` uses a global state (mostly an allocation freelist) protected by a mutex in ZTS builds. This state is used by `zend_dtoa()`, `zend_strtod()`, and variants. This creates a lot of contention in concurrent loads. `zend_dtoa()` is used to format floats to string, e.g. in sprintf, json_encode, serialize, uniqid.
Here I move the global state to the thread specific `executor_globals` and remove the mutex.
The impact on non-concurrent environments is null or negligible, but there is a considerable speed up on concurrent environments, especially on Alpine/Musl.
This is addon to the GH-13727 bug fix. When configuring the build with:
./configure CFLAGS=-Werror=strict-prototypes
libtool check for parsing nm command would fail:
checking command to parse /usr/bin/nm -B output from cc object... failed
Upstream libtool has this specific check already fixed. Note that this
works only with Autoconf version 2.72 and later and is preparation for
future compilers that might have this error enabled by default.
This is a backport of commit 03f15534a1 to
PHP-8.2 due to GH-14002 and fixes the PHP_CXX_COMPILE_STDCXX check in
ext/intl whether the specified C++ standard is mandatory or optional.
The `dnl` (Discard to Next Line) M4 macro in this combination of `m4_if`
macros and arguments isn't properly replaced and a literal `dnl` string
is appended in the configure script. The `[]dnl` works ok.
The code originally posted in GH-10599 triggers the bug for
non-persistent connections, but changing the host to `p:.` reveals that
there is also a crash bug for persistent connections.
What happens is that the persistent network stream resource gets freed, yet
stays inside EG(persistent_list). This causes a crash on shutdown when the
persistent list is getting cleared, as the engine will try to free the network
stream again.
The code in close_stream gets confused between persistent vs
non-persistent allocations when EG(active) is false.
This code was introduced in c3019a1 to fix crashes when the persistent list
gets destroyed before module shutdown is called. This is indeed a potential
problem that was fixed on the master branch in 5941cda.
This fixes the crash reason of GH-10599.
As XMLReader only exposes a single class, and the property handlers are
statically set, we don't need to store the pointer to the property
handler table inside the object.
This simplifies the code and reduces the memory required for XMLReader.
