@cname currently refers to the constant name in C. However, it is not always a (constant) name, but sometimes a function invocation, so naming it as @cvalue would be more appropriate.
Implements https://wiki.php.net/rfc/partially-supported-callables-expand-deprecation-notices
so that uses of "self" and "parent" in is_callable() and callable
type constraints now raise a deprecation notice, independent of the
one raised when and if the callable is actually invoked.
A new flag is added to the existing check_flags parameter of
zend_is_callable / zend_is_callable_ex, for use in internal calls
that would otherwise repeat the notice multiple times. In particular,
arguments to internal function calls are checked first based on
arginfo, and then again during ZPP, so the former suppresses the
deprecation notice.
Some existing tests which raised this deprecation have been updated
to avoid the syntax, but the existing version retained for maximum
regression coverage until it is made an error.
With thanks to Juliette Reinders Folmer for the RFC and initial
investigation.
Closes GH-8823.
smart_str uses an over-allocated string to optimize for append operations. Functions that use smart_str tend to return the over-allocated string directly. This results in unnecessary memory usage, especially for small strings.
The overhead can be up to 231 bytes for strings smaller than that, and 4095 for other strings. This can be avoided for strings smaller than `4096 - zend_string header size - 1` by reallocating the string.
This change introduces `smart_str_trim_to_size()`, and calls it in `smart_str_extract()`. Functions that use `smart_str` are updated to use `smart_str_extract()`.
Fixes GH-8896

This allows to combine union and intersection types together in the following form (A&B)|(X&Y)|T but not of the form (X|A)&(Y|B) or (X|A)&(Y|B)|T.
* Improve union type parsing

The new Linux 5.17 feature PR_SET_VMA_ANON_NAME can give names to
anonymous private memory, see:
https://lwn.net/Articles/867818/
It can be useful while debugging, to identify which portion of the
process's memory belongs to which subsystem.
This is how /proc/PID/maps can look like:
555ccd400000-555ccdc00000 r-xp 00000000 00:00 0 [anon:huge_code_pages]
7f6ec6600000-7f6ec6800000 rw-p 00000000 00:00 0 [anon:zend_alloc]
The first mapping is the PHP executable copied to anonymous memory by
option "opcache.huge_code_pages". The second one is a memory area for
the "zend_alloc.h" memory allocator library.
Unfortunately, it is not possible to give names to shared memory
(MAP_SHARED), because Linux MAP_SHARED really maps /dev/zero (see
shmem_zero_setup()), which makes madvise_vma_anon_name() believe this
is a file mapping, failing the prctl() with EBADF.
Add clean_module_functions() to clean functions which are registered by zend_register_functions().
The general logic of clean_module_functions() is consistent with clean_module_classes().
Add zend_ini_parse_quantity() and deprecate zend_atol(), zend_atoi()
zend_atol() and zend_atoi() don't just do number parsing.
They also check for a 'K', 'M', or 'G' at the end of the string,
and multiply the parsed value out accordingly.
Unfortunately, they ignore any other non-numerics between the
numeric component and the last character in the string.
This means that numbers such as the following are both valid
and non-intuitive in their final output.
* "123KMG" is interpreted as "123G" -> 132070244352
* "123G " is interpreted as "123 " -> 123
* "123GB" is interpreted as "123B" -> 123
* "123 I like tacos." is also interpreted as "123." -> 123
Currently, in php-src these functions are used only for parsing ini values.
In this change we deprecate zend_atol(), zend_atoi(), and introduce a new
function with the same behavior, but with the ability to report invalid inputs
to the caller. The function's name also makes the behavior less unexpected:
zend_ini_parse_quantity().

A slight imperfection in https://github.com/php/php-src/pull/7443.
As a zend_API, we should also consider other extensions that may call it in methods. This change will not break the behavior of php-src.
