`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.
In a similar model as _safe_*alloc api but for the `userland` it guards
against overflow before (re)allocation, usage concealed in fpm for now.
Modern Linux and most of BSD already have it.
Closes#8871.
Nothing new but to refactor usage b/w hash and password
extensions but using volatile pointers to be a bit safer,
allowing to expand its usage eventually.

Previously stripos/stristr would lowercase both the haystack and the
needle to reuse strpos. The approach in this PR is similar to strpos.
memchr is highly optimized so we're using it to search for the first
character of the needle in the haystack. If we find it we compare the
remaining characters of the needle manually.
The new implementation seems to perform about half as well as strpos (as
two memchr calls are necessary to find the next candidate).
Newer MSVC versions support the `inline` keyword, so we do not need to explicitly define it. We also shouldn't define `inline` to `__forceinline`, as we already have `zend_always_inline` to indicate this requirement.
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.
4. fixed indentation in some files before |
Firstly, we must not forget to set appropriate error codes for "manual"
checks in `virtual_file_ex()`.
Secondly, we must not call `php_error_docref2()` for warnings regarding
unary functions; thus, we introduce `php_win32_docref1_from_error()`.
Closes GH-6872.
php_mergesort() isn't being used for anything, and hasn't been for
a long time. Even if we wanted to use a stable sort, this isn't
the implementation we'd use...
By introducing a hook that is called whenever one of
internal_encoding / input_encoding / output_encoding changes, so
that mbstring can adjust it's internal state.
This also makes internal_encoding work with zend multibyte.
Checking for the strerror function presence is no longer needed since it
is part of the C89 standard [1] and can be safely assumed that all
current systems have it.
Check in the configure.ac and Windows defined symbol are still left
until the file library (libmagic) will be updated.

The `<limits.h>` header file is part of the standard C89 headers [1]
and on current systems can be included unconditionally.
Since PHP requires at least C89 or greater, the `HAVE_LIMITS_H` symbol
defined by Autoconf in configure.ac [2] can be ommitted and simplifed
however due to bundled file library (libmagic) and timelib still using
it, the removal there was omitted and done only in Zend.m4 file.
Current bundled libraries libtime, oniguruma, and libmagic still include
partial `HAVE_LIMITS_H` usage and will be more refactored when this is
possible.
