We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
Voidification of Zend API which always succeeded
Use bool argument types instead of int for boolean arguments
Use bool return type for functions which return true/false (1/0)
Use zend_result return type for functions which return SUCCESS/FAILURE as they don't follow normal boolean semantics
Closes GH-6002
If the length is not -1, require it to be non-negative.
Using such lengths doesn't make sense (as only -1 is special-case
to read in chunks, anything else will end up doing a huge upfront
allocation) and can lead to string allocation overflow.
A similar check is already in place for file_get_contents(). That
one does not allow -1 (and uses null instead), but this function
is explicitly specified to accept -1, so stick to that behavior.
It does not make sense to throw a `TypeError` when the stream can't be
analyzed. If `sapi_windows_vt100_support()` is used as getter, we just
return `false` in that case; if the function is used as setter, we
additionally trigger a warning.
We also fix the test cases for this function, which have been broken
before. Note that these tests are still whitespace sensitive.
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.
