A `BSTR` is similar to a `zend_string`; it stores the length of the
string just before the actual string, and thus the string may contain
NUL bytes. However, `php_com_olestring_to_string()` is supposed to
deal with arbitrary `OLECHAR*`s which may not be `BSTR`s, so we
introduce `php_com_bstr_to_string()` and use it for the only case where
we actually have to deal with `BSTR`s which may contain NUL bytes.
Contrary to `php_com_olestring_to_string()` we return a `zend_string`,
so we can save the re-allocation when converting to a `zval`.
We also cater to `php_com_string_to_olestring()` not being binary safe,
with basically the same fix we did for `php_com_olestring_to_string()`.
`atol()` returns a `long` which is not the same as `zend_long` on
LLP64; we use `ZEND_ATOL()` instead.
There is no need for a new test case, since filesize_large.phpt already
tests for that behavior; unfortunately, the FTP test suite relies on
`pcntl_fork()` and therefore cannot be run on Windows.
Even if the length of a maker note does not match our expectations
(either because the maker note is corrupted, or because our
expectations do not quite match reality), there is no need to let
parsing fail; we can still go on parsing the other meta information.
If the current character is a line break character, it cannot be a tab
or space character, so we would always fail with an invalid sequence
error. Obviously, these `scan_stat == 4` conditions are meant to be
exclusive.
Furthermore, if `in_pp == NULL || in_left_p == NULL` is true, we hit a
segfault if we are not returning right away. Obviously, the additional
constraints don't make sense, so we remove them.
As its name suggests, `sqlite3_data_count` returns the number of
columns in the current row of the result set; we are interested in the
number of columns regardless of the current row, so we have to use
`sqlite3_column_count` instead.
The color resolution is expected in bits 4-6 of the packed fields byte
of the logical screen descriptor (byte 10 of the GIF data stream),
according to the specification[1], section 18.

We map the POSIX semantics of `IPC_PRIVATE` by creating unnamed file
mapping objects on Windows. While that is not particularly useful for
ext/shmop, which is the only bundled extension which uses `shmget()`,
it may be useful for external extensions.
I stumbled upon this while debugging a strange issue with
stream_socket_client() where it randomly throws out errors when
the connection timeout is set to below 1s. The logic to calculate
time difference in php_openssl_subtract_timeval() is wrong when
a.tv_usec < b.tv_usec, causing connection errors before the timeout
is reached.
We have to free the retrieved text content; to keep the code readable,
we extract a helper function to check for empty nodes. Unfortunately,
we cannot use xmlIsBlankNode(), because that also recognizes whitespace
only text content.
We also make sure to properly handle NULL returns from
xmlNodeGetContent().
This commit brings some substantial changes in behaviour due to the weird implementation.
This will be fixed in master due to BC concerns.
This reverts commit 1333b46d6d.
In commit a7305eb539 the last_message
field of the connection object was changed to be always non-persistent.
But there is a place on change_user path that still treats it
depending on conn->persistent flag. This will cause PHP crash after
com_change_user success when there is last_message set
The comment on `PS_VALIDATE_SID_FUNC(files)` is very clear that the
function is supposed to return `SUCCESS` if the session already exists.
So to detect a collision, we have to check for `SUCCESS`, not
`FAILURE`.
We also fix the wrong condition in session_regenerate_id() as well.
The skip message must start with the word 'skip', otherwise the test will not be skipped.
