#35449 [Fbk->Opn]: stream_socket_recvfrom() docs don't mention about it's buffer bypassing

ID: 35449 User updated by: profic at kursknet dot ru Reported By: profic at kursknet dot ru -Status: Feedback +Status: Open Bug Type: Documentation problem PHP Version: Irrelevant New Comment: Hm. I didn't suppose, that documentashion problem needs test case. Here is one: <?php $s = stream_socket_client('tcp://localhost:80', $errno, $error, 5); stream_socket_sendto($s, "GET http://localhost/ HTTP/1.0\r\n"); stream_socket_sendto($s, "Host: localhost\r\n"); stream_socket_sendto($s, "\r\n"); echo "stream_get_line():\n"; var_dump(stream_get_line($s, 1500, "\r\n")); echo "stream_socket_recvfrom():\n"; var_dump(stream_socket_recvfrom($s, 100)); echo "stream_get_contents():\n"; var_dump(stream_get_contents($s, 100)); ?> Output of it for my system is: stream_get_line(): string(15) "HTTP/1.1 200 OK" stream_socket_recvfrom(): bool(false) stream_get_contents(): string(100) "Date: Sat, 03 Dec 2005 14:32:05 GMT Server: Apache/2.0.54 (Win32) PHP/5.1.0RC5-dev Content-Length:" As you can see stream_socket_recvfrom() returns false the same as when "end of socket" is reached. And it is reached. All incoming data from socket is stored in stream buffer, call to stream_get_contents() proves that. Previous Comments: ------------------------------------------------------------------------ [2005-11-29 14:26:30] vrana@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2005-11-28 15:30:49] profic at kursknet dot ru Description: ------------ Calls to stream_socket_recvfrom() on socket-based streams, after calls to buffer-based stream funcions (like fread(), steam_get_line()) may lead to unexpected (to user) results as it is bypass stream buffer. Thus is seems to be a good idea to have warning/note in documentation of stream_socket_recvfrom() about this. Elsewise it can be runtime notice in case of use stream_socket_recvfrom() on stream with non-empty buffer. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35449&edit=1
