When mapping the file, we need to pass the proper `dwFileOffsetHigh`
instead of `0`.

Closes GH-7158.
When doing a non finishing flush, BZ2_bzCompress() returns BZ_FLUSH_OK
(not BZ_FINISH_OK) what requires us to do further flushes right away.
We also refactor the while-loop as do-loop.
Closes GH-7113.
When the memory limit is reduced using an `ini_set("memory_limit", ..)`
below the currently allocated memory, the out-of-memory check overflowed.
Instead of implementing additional checks during allocation,
`zend_set_memory_limit()` now validates the new memory limit. When
below the current memory usage the ini_set call will fail and throw
a warning.
This is part of GH-7040.
This is not guaranteed to work, since the actual server name may only
be given as SAN. Since we're doing the peer verification later anyway
(using the respective context options as appropriate), there is no need
to even supply a server name when verifying against the Windows cert
store.
Closes GH-7060.
For concatenation, the in-place variant can be much more efficient,
because it will reallocate the string in-place. Special-case the
typed property compound assignment code for the case where we
concatenate to a string, in which case we know that the result
will also be a string, and we don't need the type check anyway.
If ZTS is enabled, this can cause cwd_globals_ctor() to be called
multiple times, each with a freshly allocated virtual_cwd_globals
instance. At shutdown time however, cwd_globals_dtor() will call
realpath_cache_clean(), which then possibly cleans up the same
realpath_cache instance more than once. Using AddressSanitzer, this
shows up as a heap use-after-free.
To avoid this, add a helper function to do the actual work on one
instance of a realpath_cache, and call it both from cwd_globals_dtor()
and realpath_cache_clean(). The former uses the virtual_cwd_globals
parameter passed in via the destructor, the latter uses the CWDG()
macro.
Now that we properly dereference references of the superglobals. we
also need to dereference contained references to avoid to string
conversion.
Closes GH-7014.
This PR replaces the bundled libgd includes from #include <foo.h> with
#include "foo.h" for gd-related headers to avoid including headers that
may be available in system directories instead of the expected local
headers.
Closes GH-6975.
If `SQLDescribeParam()` fails for a parameter, we must not assume
`SQL_LONGVARCHAR` for any param which is not `PDO_PARAM_LOB`. At least
mapping `PDO_PARAM_INT` to `SQL_INTEGER` should be safe, and not
introduce a BC break.
Closes GH-6973.
We need to cater to references, when traversing the files to extract.
While we're at it, we move the `zval_file` declaration into a narrower
scope.
Closes GH-6959.
Make sure that the previous opline is part of the same block,
otherwise it may be non-dominating.
The test case does not fail on PHP-7.4, but I think the general
problem can appear on 7.4 as well, so I'm applying the patch to
that branch.
First we need to properly clear the `inbuf`, what is an amendment to
commit d2881adcbc[1].
Then we need to report `php_pollfd_for_ms()` failures right away; just
setting `errno` does not really help, since at least in some cases it
would have been overwritten before we actually could check it. We use
`php_socket_strerror()` to get a proper error message, and define
`ETIMEDOUT` to the proper value on Windows; otherwise we catch the
definition in errno.h, which is not compatible with WinSock. The
proper solution for this issue would likely be to include something
like ext/sockets/windows_common.h.
Finally, we ensure that we only report warnings using `inbuf`, if it is
not empty.

Closes GH-6718.
The `StrLen_or_IndPtr` parameter usually may be `SQL_NO_TOTAL`; we need
to cater to that possibility to avoid working with negative string
lengths and other issues. A noteable exemption are calls to
`SQLGetData()` which return `SQL_SUCCESS`; in that case `SQL_NO_TOTAL`
can not occur.
Closes GH-6809.
`php_stream_can_cast()` forwards to `_php_stream_cast()` with `ret` set
to `NULL`. `php_pgsql_fd_cast()` needs to cater to that, because
otherwise the stream would report that it is not castable.
This *might* fix https://bugs.php.net/73903.
Closes GH-6888.
Firstly, we must not forget to set appropriate error codes for "manual"
checks in `virtual_file_ex()`.
Secondly, we must not call `php_error_docref2()` for warnings regarding
unary functions; thus, we introduce `php_win32_docref1_from_error()`.
Closes GH-6872.
The function name should be kept if Closure was created from the function which is marked as ZEND_ACC_CALL_VIA_TRAMPOLINE, because it is not a one-time thing and it may be called multiple times.
Closes GH-6867.
`buf` may contain NUL bytes, so we must not use `strcspn()` but rather
a binary safe variant. However, we also must not detect a stray CR as
line ending, and since we only need to check line endings at the end
of the buffer, we can nicely optimize.

Closes GH-6836.
Function info for curl_exec() incorrect specified that the
function cannot return true. This is already fixed in PHP 8,
as the func info entry was removed there.
We use the proper type, and make sure that no overflow can occur by
using `safe_emalloc()` (we can assume that neither string length is
`SIZE_MAX`).
Closes GH-6845.
When `SSL_read()` after `SSL_shutdown()` fails with `SSL_ERROR_SYSCALL`,
we should not warn about this, because it is likely caused by the peer
having closed the connection without having sent a close_notify
shutdown alert.

`xmlNewNs()` does not XML encode the passed `href`, so we need to do
that manually.
