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.
These stats are used to check whether the file exists -- they
should not generate errors. Having the flag set is particularly
important for custom stream wrappers.
Don't report EAGAIN/EWOULDBLOCK as errors for fwrite on
non-blocking socket streams. This matches behavior for fread,
as well as behavior for plain file streams.
Closes GH-5026.
We need to update the value even if new_value is NULL. In particular,
it should be reset back to NULL after each request if the setting was
not specified on startup. Otherwise we leave dangling pointers.
We switch the cookie value parsing function from `php_url_decode()` to
`php_raw_url_decode()`, so that cookie values are now parsed according
to RFC 6265, section 4.1.1. We also refactor to remove duplicate code
without changing the execution flow.
We add the `is_seekable` member to `php_stdio_stream_data`, and prefer
that over `is_pipe`, since the latter is simply a misnomer. We keep
`is_pipe` for now for Windows only, though, because we need special
support for pipes there. We also fix the misaligned bitfield which
formerly took 33 bit.
First, the limitation already doesn't trigger if you copy the whole
file (i.e. use copy() or stream_copy_to_stream() and don't specify
a length). This happens because length will be 0 at the time of the
check and only later calculated based on the file size. This means
that we're already completely blowing the length limit for what is
likely the most common case, and it doesn't seem like anyone complained
about that.
Second, the premise of the code comment ("to avoid runaway swapping")
seems incorrect to me. Because this performs a file-backed non-private
mmap, no swap backing is needed for the mapping. Concerns over "memory
usage" are also misplaced, as this is a virtual mapping.
