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:

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.

Move the load_wsdl_ex call into the zend_try that destroys the
docs hash table. The wsdl will be inserted into docs early on,
and will thus be released on subsequent bailout.
We remove the arbitrary restriction to `INT_MAX`; it is superfluous on
32bit systems where `ZEND_LONG_MAX == INT_MAX` anyway, and not useful
on 64bit systems, where larger files should be readable, if the
`memory_limit` is large enough.
Closes GH-6648.
That bug report originally was about `parse_url()` misbehaving, but the
security aspect was actually only regarding `FILTER_VALIDATE_URL`.
Since the changes to `parse_url_ex()` apparently affect userland code
which is relying on the sloppy URL parsing[1], this alternative
restores the old parsing behavior, but ensures that the userinfo is
checked for correctness for `FILTER_VALIDATE_URL`.

The default encoding of filenames in a ZIP archive is IBM Code Page
437. Phar, however, only supports UTF-8 filenames. Therefore we have
to mark filenames as being stored in UTF-8 by setting the general
purpose bit 11 (the language encoding flag).
The effect of not setting this bit for non ASCII filenames can be seen
in popular tools like 7-Zip and UnZip, but not when extracting the
archives via ext/phar (which is agnostic to the filename encoding), or
via ext/zip (which guesses the encoding). Thus we add a somewhat
brittle low-level test case.
Closes GH-6630.
Check open_basedir after the fallback to the system's temporary
directory in tempnam().
In order to preserve the current behavior of upload_tmp_dir
(do not check explicitly specified dir, but check fallback),
new flags are added to check open_basedir for explicit dir
and for fallback.
Closes GH-6526.
When extracting compressed files from an uncompressed Phar, we must not
use the direct file pointer, but rather get an uncompressed file
pointer.
We also add a test to show that deflated and stored entries are
properly extracted.
This also fixes#79912, which appears to be a duplicate of #69279.

This is mainly to work around https://github.com/curl/curl/issues/6455,
but not building the mime structure for empty hashtables is a general
performance optimization, so we do not restrict it to affected cURL
versions (7.56.0 to 7.75.0).
The minor change to bug79033.phpt is unexpected, but should not matter
in practice.
Closes GH-6606.
The internal function `_readline_command_generator()` modifies the
internal array pointer of `readline_completion_function()`'s return
value. We therefore separate the array, what also avoids failing
assertions regarding the array refcount.
Closes GH-6582.
We must not assume that the first end of central dir signature in a ZIP
archive actually designates the end of central directory record, since
the data in the archive may contain arbitrary byte patterns. Thus, we
better search from the end of the data, what is also slightly more
efficient.
There is, however, no way to detect the end of central directory
signature by searching from the end of the ZIP archive with absolute
certainty, since the signature could be part of the trailing comment.
To mitigate, we check that the comment length fits to the found
position, but that might still not be the correct position in rare
cases.
Closes GH-6507.
To avoid that `parse_url()` returns an erroneous host, which would be
valid for `FILTER_VALIDATE_URL`, we make sure that only userinfo which
is valid according to RFC 3986 is treated as such.
For consistency with the existing url parsing code, we use ctype
functions, although that is not necessarily correct.
In the case of a stream with no filters, php_stream_fill_read_buffer
only reads stream->chunk_size into the read buffer. If the stream has
filters attached, it could unnecessarily buffer a large amount of data.
With this change, php_stream_fill_read_buffer only proceeds until either
the requested size or stream->chunk_size is available in the read buffer.

This fixes two related issues:
1. When a PS with cursor is used in store_result/get_result,
perform a COM_FETCH with maximum number of rows rather than
silently switching to an unbuffered result set (in the case of
store_result) or erroring (in the case of get_result).
In the future, we might want to make get_result unbuffered for
PS with cursors, as using cursors with buffered result sets
doesn't really make sense. Unlike store_result, get_result
isn't very explicit about what kind of result set is desired.
2. If the client did not request a cursor, but the server reports
that a cursor exists, ignore this and treat the PS as if it
has no cursor (i.e. to not use COM_FETCH). It appears to be a
server side bug that a cursor used inside an SP will be reported
to the client, even though the client cannot use the cursor.
Fixes bug #64638, bug #72862, bug #77935.
Closes GH-6518.
`phar_path_check()` already strips a leading slash, so we must not
attempt to strip the trailing slash from an now empty directory name.
Closes GH-6508.
Like the test title and some comments in this test describe, this test
was supposed to have `::prepare()` failing because `LOAD DATA INFILE`
would not be supported as prepared statement, and then the test checks
whether follow-up queries would succeed. However, `LOAD DATA INFILE`
is supported for prepared statements at least on Windows with mysqlnd,
so the test does no longer test what it is supposed to do. Therefore,
we drop it.
Closes GH-6509.
When we receive an error while reading a result set, we should
assume that no more result sets are available. libmysqlclient
implements the same behavior.
