We have to log errors in `stream_opener` callbacks to the wrapper's
error log, because otherwise we may pick up an unrelated `errno` or a
most generic message.
Closes GH-6187.
If restoring of any not registered built-in wrapper is requested, the
function is supposed to fail with a warning, so we have to check this
condition first.
Furthermore, to be able to detect whether a built-in wrapper has been
changed, it is not sufficient to check whether *any* userland wrapper
has been registered, but rather whether the specific wrapper has been
modified.
Closes GH-6183.
Passing `NULL` as `lpFileSizeHigh` to `GetFileSize()` gives wrong
results for files larger than 0xFFFFFFFF bytes. We fix this by using
`GetFileSizeEx()`, and let the mapping fail, if the file size is too
large for the architecture.
Closes GH-5319.
A recent commit[1] which fixed a memory leak introduced a regression
regarding the formerly liberal handling of IP addresses to bind to. We
fix this by reverting that commit, and fix the memory leak where it
actually occurs. In other words, this fix is less intrusive than the
former fix.

The `timercmp()` manpage[1] points out that some systems have a broken
implementation which does not support `>=`. This is definitely the
case for the Windows SDK, which only supports `<` and `>`.

We must not cast `size_t` to `int` (unless the `size_t` value is
guaranteed to be less than or equal to `INT_MAX`). In this case we can
declare `array_len` as `size_t` in the first place.
This is actually about three distinct issues:
* If an empty string is passed as $address to `stream_socket_sendto()`,
the `sa` is not initialized, so we must not pass it as `addr` to
`php_stream_xport_sendto()`.
* On POSIX, `recvfrom()` truncates messages which are too long to fit
into the specified buffer (unless `MSG_PEEK` is given), discards the
excessive bytes, and returns the buffer length. On Windows, the same
happens, but `recvfrom()` returns `SOCKET_ERROR` with the error code
`WSAEMSGSIZE`. We have to catch this for best POSIX compatibility.
* In `php_network_parse_network_address_with_port()`, we have to zero
`in6` (not only its alias `sa`) to properly support IPv6.

To be able to see changes done only with `SetEnvironmentVariable()`, we
have to use `GetEnvironmentStrings()` instead of `environ`, because the
latter sees only changes done with `putenv()`.
For best backward compatibility we're using `GetEnvironmentStringsA()`;
switching to the wide string version likely makes sense for master,
though.
This is a backport of fcdc0a6db0
to the PHP-7.3 branch. We need to make sure that OnUpdateString
is also called for a NULL value, otherwise the reset of the encoding
at the end of the request will not work.
I believe I already tried to land this before once, but it didn't
actually end up on the PHP-7.3 branch due to a push conflict that
I only noticed just now.
This makes the stream opening actually fail, and avoids assertion
failures when we tokenize with EG(exception) set.
Also avoid throwing an additional warning after an exception has
already been thrown.
stream_get-line repeatedly calls php_stream_fill_read_buffer until
enough data is accumulated in buffer. However, when stream contains
filters attached to it, then each call to fill buffer essentially
resets buffer read/write pointers and new data is written over old.
This causes stream_get_line to skip parts of data from stream
This patch fixes such behavior, so fill buffer call will append.
