The php_stream_read() and php_stream_write() functions now return an ssize_t value, with negative results indicating failure. Functions like fread() and fwrite() will return false in that case. As a special case, EWOULDBLOCK and EAGAIN on non-blocking streams should not be regarded as error conditions, and be reported as successful zero-length reads/writes instead. The handling of EINTR remains unclear and is internally inconsistent (e.g. some code-paths will automatically retry on EINTR, while some won't). I'm landing this now to make sure the stream wrapper ops API changes make it into 7.4 -- however, if the user-facing changes turn out to be problematic we have the option of clamping negative returns to zero in php_stream_read() and php_stream_write() to restore the old behavior in a relatively non-intrusive manner.
