This version replaces SPACEs before the meridian with NARROW NO-BREAK
SPACEs. Thus, we split the affected test cases as usual.
(cherry picked from commit 8dd51b462d)
Fixes GH-10262.
A copy of this piece of code exists in zend_jit_compile_side_trace(),
but there, the leak bug does not exist.
This bug exists since both copies of this piece of code were added in
commit 4bf2d09ede
zend_get_property_guard previously assumed that at least "str" has a
pre-computed hash. This is not always the case, for example when a
string is created by bitwise operations, its hash is not set. Instead of
forcing a computation of the hashes, drop the hash comparison.

If, for whatever reason, the random_fd has been assigned file descriptor `0` it
previously failed to close during module shutdown, thus leaking the descriptor.
As a performance optimization, mbstring implements some functions using
tables which give the (byte) length of a multi-byte character using a
lookup based on the value of the first byte. These tables are called
`mblen_table`.
For many years, the mblen_table for SJIS has had '2' in position 0x80.
That is wrong; it should have been '1'. Reasons:
For SJIS, SJIS-2004, and mobile variants of SJIS, 0x80 has never been
treated as the first byte of a 2-byte character. It has always been
treated as a single erroneous byte. On the other hand, 0x80 is a valid
character in MacJapanese... but a 1-byte character, not a 2-byte one.
The same applies to bytes 0xFD-FF; these are 1-byte characters in
MacJapanese, and in other SJIS variants, they are not valid (as the
first byte of a character).
Thanks to the GitHub user 'youkidearitai' for finding this problem.
The issue was that passwd was empty for the issue reporter, but the test
expected passwd to be non-empty. An empty passwd can occur if there is
no (encrypted) group password set up.
This occurs because the array of properties is a single element with an
integer key, not an associative array. Therefore it is a packed array
and thus the assumption the iteration macro makes is invalid.
This restores the behaviour of PHP<8.2.

Until https://github.com/php/php-src/pull/10098 default constructors were sometimes documented, sometimes omitted. The above PR made adding documentation for constructor of all non-abstract classes required. However, this is not desired when such a class inherits a constructor from its parent. The current PR fixes the behavior the following way:
- documents inherited constructors (along with destructors)
- makes it possible to generate/replace the methodsynopsis of implicit default constructors which don't have a stub counterpart
When the validation logic for param->type was added, the logic did not
account for the case where param could be NULL. The existing code did
take that into account as can be seen in the `if (param)` check below.
Furthermore, phpdbg_set_breakpoint_expression even calls
phpdbg_create_conditional_break with param == NULL.
Fix it by placing the validation logic inside a NULL check.
The 'h' flag makes mb_convert_kana convert zenkaku hiragana to hankaku
katakana; 'k' makes it convert zenkaku katakana to hankaku katakana.
When working on the implementation of mb_convert_kana, I added some
additional checks to catch combinations of flags which do not make
sense; but there is no conflict between 'h' and 'k' (they control
conversions for two disjoint ranges of codepoints) and this combination
should not have been restricted.
Thanks to the GitHub user 'akira345' for reporting this problem.
Closes GH-10174.
Commit 6c25413183 added the flag ZEND_JIT_EXIT_INVALIDATE which
resets the trace handlers in zend_jit_trace_exit(), but forgot to
lock the shared memory section.
This could cause another worker process who still saw the
ZEND_JIT_TRACE_JITED flag to schedule ZEND_JIT_TRACE_STOP_LINK, but
when it arrived at the ZEND_JIT_DEBUG_TRACE_STOP, the handler was
already reverted by the first worker process and thus
zend_jit_find_trace() fails.
This in turn generated a bogus jump offset in the JITed code, crashing
the PHP process.
Commit 6c25413 added the flag ZEND_JIT_EXIT_INVALIDATE which resets
the trace handlers in zend_jit_trace_exit(), but forgot to consider
that on ZEND_JIT_TRACE_STOP_LINK, this changed handler gets passed to
zend_jit_find_trace(), causing it to fail, either by returning 0
(results in bogus data) or by aborting due to ZEND_UNREACHABLE(). In
either case, this crashes the PHP process.
I'm not quite sure how to fix this multi-threading problem properly;
my suggestion is to just fail the zend_jit_trace() call. After all,
the whole ZEND_JIT_EXIT_INVALIDATE fix was about reloading modified
scripts, so there's probably no point in this pending zend_jit_trace()
call.
