As of commit 81b2f3e[1], `parse_url()` accepts URLs with a zero port,
but does not report that port, what is wrong in hindsight.
Since the port number is stored as `unsigned short` there is no way to
distinguish between port zero and no port. For BC reasons, we thus
introduce `parse_url_ex2()` which accepts an output parameter that
allows that distinction, and use the new function to fix the behavior.
The introduction of `parse_url_ex2()` has been suggested by Nikita.

We cannot simply switch to use_result here, because the fetch_row
methods in get_result mode and in use_result/store_result mode
are different: In one case it accepts a statement, in the other
a return value zval. Thus, doing a switch to use_result results
in a segfault when trying to fetch a row.
Actually supporting get_result with cursors would require adding
cursor support in mysqlnd_result, not just mysqlnd_ps. That would
be a significant amount of effort and, given the age of the issue,
does not appear to be particularly likely to happen soon.
As such, we simply generate an error when using get_result()
with cursors, which is much better than causing a segfault.
Instead, parameter binding needs to be used.
Unless `SQLGetData()` returns `SQL_SUCCESS` or `SQL_SUCCESS_WITH_INFO`,
the `StrLen_or_IndPtr` output argument is not guaranteed to be properly
set. Thus we handle retrieval failure other than `SQL_ERROR` by
yielding `false` for those column values and raising a warning.
Closes GH-6281.
Set error_info when we fail to read a packet, instead of throwing
a warning. Additionally we also need to populate the right
error_info in rowp_read -- we'll later take the error from the
packet, not the connection.
No test case, as this is hard to reliably test. I'm using the
test case from:
https://github.com/php/php-src/pull/2131#issuecomment-538374838
We have to error on unhandled exceptions in FFI callbacks, to avoid
passing back undefined values.
This has been discussed and agreed upon in a previous PR[1].

Closes GH-6366.
Make sure deadlock errors are properly propagated and reports in
a number of places in mysqli and PDO MySQL.
This also fixes a memory and a segfault that can occur under these
conditions.
libxml2 has no particular issues parsing HTML strings with NUL bytes;
these just cause truncation of the current text content, but parsing
continues generally. Since `::loadHTMLFile()` already supports NUL
bytes, `::loadHTML()` should as well.
Note that this is different from XML, which does not allow any NUL
bytes.
Closes GH-6368.
A recent bug fix regarding symlinks claimed:
> After resolving reparse points, the path still may be a reparse
> point; in that case we have to resolve that reparse point as well.
While that is basically correct, some reparse points may point to
inaccessible system folders (e.g. `IO_REPARSE_TAG_DEDUP` points to
"\System Volume Information"). Since we don't know details about
arbitrary reparse points, and are mainly interested in nested symlinks,
we take a step back, and only resolve `IO_REPARSE_TAG_SYMLINK` for now.

`ADD_EXTENSION_DEP()` relies on the `PHP_<extname>` config variables to
be set to `"yes"`, and since the standard and date extension are always
enabled, we define the respective variables uncoditionally.
Closes GH-6383.
libc-client expects `TYPEMESSAGE` with an explicit subtype of `RFC822`
to have a `nested.msg` (otherwise there will be a segfault during
free), but not to have any `contents.text.data` (this will leak
otherwise).
Closes GH-6345.
The original fix for that bug[1] broke the formerly working composition
of message/rfc822 messages, which results in a segfault when freeing
the message body now. While `imap_mail_compose()` does not really
support composition of meaningful message/rfc822 messages (although
libc-client appears to support that), some code may still use this to
compose partial messages, and using string manipulation to create the
final message.
The point is that libc-client expects `TYPEMESSAGE` with an explicit
subtype of `RFC822` to have a `nested.msg` (otherwise there will be a
segfault during free), but not to have any `contents.text.data` (this
will leak otherwise).

OCB mode ciphers were already exposed to openssl_encrypt/decrypt,
but misbehaved, because they were not treated as AEAD ciphers.
From that perspective, OCB should be treated the same way as GCM.
In OpenSSL 1.1 the necessary controls were unified under
EVP_CTRL_AEAD_* (and OCB is only supported since OpenSSL 1.1).
Closes GH-6337.
If unsupported `$search_criteria` are passed to `imap_sort()`, the
function returns an empty array, but there is also an error on the
libc-client error stack ("Unknown search criterion: UNSUPPORTED
(errflg=2)"). If, on the other hand, unsupported `$criteria` or
unsupported `$flags` are passed, the function returns `false`. We
solve this inconsistency by returning `false` for unsupported
`$search_criteria` as well.
Closes GH-6332.
Unless `topbod` is of `TYPEMULTIPART`, `mail_free_body()` does not free
the `nested.part`; while we could do this ourselves, instead we just
ignore additional bodies in this case, i.e. we don't attach them in the
first place.
Closes GH-6321.
We separate the input arrays and all sub-arrays to avoid modification
of the passed parameters.
This should be rewritten to use `zend_string`s for the "master" branch.
Closes GH-6316.
