Fix #78470: odbc_specialcolumns() no longer accepts $nullable
It is mandatory to pass either `SQL_NO_NULLS` or `SQL_NULLABLE` as
tenth parameter to `SQLSpecialColumns()`; otherwise the function call
fails. Therefore the user must be allowed to pass the desired value
as parameter to `odbc_specialcolumns()` again.
Fix #76735: Incorrect message in fopen on invalid mode
We have to log errors in `stream_opener` callbacks to the wrapper's
error log, because otherwise we may pick up an unrelated `errno` or a
most generic message.
Fix #77493: curl_basic_009 fails with newer curl versions
libcurl 7.62.0 introduced a maximum protocol length of 8, so this test
case failed with `CURLE_URL_MALFORMAT`. While this is lifted to 40 as
of libcurl 7.65.0, and this test case has already been fixed with
commit e27301c[1], we restore the original intention to check for a
`CURLE_UNSUPPORTED_PROTOCOL ` error.
If restoring of any not registered built-in wrapper is requested, the
function is supposed to fail with a warning, so we have to check this
condition first.
Furthermore, to be able to detect whether a built-in wrapper has been
changed, it is not sufficient to check whether *any* userland wrapper
has been registered, but rather whether the specific wrapper has been
modified.
Fix #79423: copy command is limited to size of file it can copy
Passing `NULL` as `lpFileSizeHigh` to `GetFileSize()` gives wrong
results for files larger than 0xFFFFFFFF bytes. We fix this by using
`GetFileSizeEx()`, and let the mapping fail, if the file size is too
large for the architecture.
Instead of attempting to map large files into memory at once, we map
chunks of at most `PHP_STREAM_MMAP_MAX` bytes, and repeat that until we
hit the point where `php_stream_seek()` fails (see bug 54902), and copy
the rest of the file by reading and writing small chunks.
We also fix the mapping behavior for zero bytes on Windows, which did
not error (as with `mmap()`), but would have mapped the remaining file.

Fix #78179: mysqli/mysqlnd transaction extensions
MariaDB versioning created a mess with regarding testing
features based on version. We sidestep the problem here
by assuming the extensions are present, and if a syntax
error occurs with a SQL mode TRANS_START_READ_WRITE |
TRANS_START_READ_ONLY enabled, then output the same
warning as before.
> The size of BLOB/TEXT data inserted in one transaction is greater

Fix bug #80107: Handling of large compressed packets
Bug #80107 Add test for mysqli_query() fails for ~16 MB long query when compression is enabled
Fix bug #80107: Handling of large compressed packets
There's two layers of packet splitting going on. First, packets
need to be split into having a payload of exactly 2^24-1 bytes or
being the last packet. If the split packet has size between 2^24-5
and 2^24-1 bytes, the compressed packets also needs to be split,
though the choice of split doesn't matter here. I'm splitting off
the first 8192 bytes, as that's what I observe libmysqlclient to be
doing.
Add db2_execute() to the list of functions accessing the local
scope. Ideally the API wouldn't do that, but it seems most
pragmatic to address this on the opcache side at this point.
Fix #80067: Omitting the port in bindto setting errors
A recent commit[1] which fixed a memory leak introduced a regression
regarding the formerly liberal handling of IP addresses to bind to. We
fix this by reverting that commit, and fix the memory leak where it
actually occurs. In other words, this fix is less intrusive than the
former fix.
Fix #79825: opcache.file_cache causes SIGSEGV with custom opcode handlers
Modules may have changed after restart which can cause dangling pointers from custom opcode handlers in the second-level cache files. This fix includes the installed module names and versions in the accel_system_id hash as entropy. Closes GH-5836

Handle memory limit error during string reallocation correctly
Do not decrement the refcount before allocating the new string,
as the allocation operation may bail out and cause a use-after-free
lateron. We can only decrement the refcount once the allocation
has succeeded.
Fix throwing of yield from related exceptions into generator
Use the general zend_generator_throw_exception() helper for this.
Otherwise we don't handle the off-by-one opline correctly (should
we maybe just stop doing that?)
This is a followup to ad750c3bb6e7b48384c6265eb9d3bcf5b4000652,
which fixed a different yield from exception handling problem that
happened to show up in the same test case from oss-fuzz #25321.
Now both issues should be fixed.
This can happen if zend_call_function inserted a dummy frame,
and we already switched to the dummy frame in leave_helper,
and an exception is thrown during CV destruction.
