The `encoding` attribute of the XML declaration is optional; it is good
practice to use external encoding information where available if it is
missing. Thus, we check for `charset` info of `Content-Type` headers,
and see whether the encoding is supported.
We cater to trailing parameters and quoted-strings, but not to escaped
backslashes and quotes in quoted-strings, since no known character
encoding contains these anyway.

This issue came up recently in a bug report[1]; without the error code,
users can barely guess why the function failed.

Closes GH-6745.
When opening HTTP streams, and reading the headers, we currently
discard header lines longer than `HTTP_HEADER_BLOCK_SIZE` (1024 bytes).
While this is not generally forbidden by RFC 7230, section 3.2.5, it
is not generally allowed either, since that may change the "message
framing or response semantics".
We thus fix this by allowing arbitrarily long header lines.
Closes GH-6720.
So far, `SendText()` simply separates potential email address lists at
any comma, disregarding that commas inside a quoted-string do not
delimit addresses. We fix that by introducing an own variant of
`strtok_r()` which caters to quoted-strings.
We also make `FormatEmailAddress()` aware of quoted strings.
We do not cater to email address comments, and potentially other quirks
of RFC 5322 email addresses, but catering to quoted-strings is supposed
to solve almost all practical use cases.

The lack of such a check leads to false-passes of tests on Windows
which expect no output, but produce a segfault or similar issue. I
discovered this a while ago due to bad tests in an extension I maintain.
Closes GH-6722.
When no test paths are specified this shows up when 'make test' is used on a PECL extension without specifying tests to run (or in php-src too, I guess...)
Closes GH-6717.
First, the `bzip2.compress` filter has the same issue as `zlib.deflate`
so we port the respective fix[1] to ext/bz2.
Second, there is still an issue, if a stream with an attached
compression filter is flushed before it is closed, without any writes
in between. In that case, the compression is never finalized. We fix
this by enforcing a `_php_stream_flush()` with the `closing` flag set
in `_php_stream_free()`, whenever a write filter is attached. This
call is superfluous for most write filters, but does not hurt, even
when it is unnecessary.

Closes GH-6703.
zend_find_array_dim_slow() may throw, make sure to handle this.
This backports the code we already use for this on PHP-8.0,
and also backports an exception check that makes this easier to
catch.
Rather than segfaulting because sname is missing lateron, report
a FAIL here. As this indicates a server bug, the errors is reported
as an out of band warning, rather than a client error.
This fixes the PHP side of bug #80713.
openssl_pkey_new() fetches various options from the config file --
most of these are optional, and not specifying them is not an error
condition from the perspective of the user. Unfortunately, the
CONF_get_string() API pushes an error when accessing a key that
doesn't exist (_CONF_get_string does not, but that is presumably a
private API). This commit adds a helper php_openssl_conf_get_string()
that automatically clears the error in this case. I've found that
OpenSSL occasionally does the same thing internally:

Closes GH-6699.
We need to first clean the symtable and then check whether a cache
slot is available for it. Otherwise, it may happen that a destructor
runs while cleaning the table and uses up all the remaining slots
in the cache.
This is particularly insidious because once we overflow the cache,
the first pointer we modify is symtable_cache_ptr, making it hard
to understand what happened after the fact.
Fixes oss-fuzz #30815.
The PAM service requires the terminating null to be part
of the communication.
Tested with MariaDB-10.4(pam) and Percona Server 5.7.32(auth_pam_compat).
Also changed MySQL Enterprise test to the server side plugin, authentication_pam
as opposed to the client plugin mysql_clear_password.
Add additional check for pamtest user and pam service file as
all are required for the test.
More importantly, test result should actually succeed.
Thanks Geoff Montee for bug report.
Closes GH-78680.
We need to always destroy current, not just when iter.data is not
set.
Take this opportunity to clean up the iterator destructor code a
bit, to remove redundant checks and incorrect comments.
Version numbers are not supposed to be localized, so we must not apply
locale dependent parsing with `atof()`.
Using `php_version_compare()` might even be better.
Closes GH-6668.
We need to handle the case where a CRLF after a Bcc header is not the
beginning of a folding marker, because in that case the Bcc header was
not the last "thing".
Closes GH-6666.
We must not use the locale dependent `atof()`, but instead use the
(hopefully) locale independent `zend_strtod()`, when converting string
representations of floating point numbers which are sent by the server.
Closes GH-6665.
When Phars are flushed, a new temporary file is created for each entry
which should be compressed, and the `compressed_filesize` is retrieved.
Afterwards, the Phar manifest is written, and only after that the files
are copied to the actual Phar. So for each such entry there is an open
temp file, what easily exceeds the limit.
Therefore, we use a single temporary file for all entries, and store
the start offset in the otherwise unused `header_offset` member. We
ensure that the `cfp` members are properly set to NULL even if flushing
fails, to avoid use after free scenarios.
This solution is based on a suggestion by @lserni[1].
Closes GH-6643.
