Bug description:Add support to establish > 1 persistent connection to the same
UNIX socket
Description:
------------
I found that it is possible to establish > 1 persistent connections with
unique_id to TCP socket using syntax provided below:
$s1=stream_socket_client('tcp://127.0.0.1:1234/id1', $errno, $errstr, 3,
STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT);
$s2=stream_socket_client('tcp://127.0.0.1:1234/id2', $errno, $errstr, 3,
STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT);
id1 and id2 are an unique identifiers which i can use later. This way i can
use > 1 persistent connection to the same host->port. Unfortunately it does
not work for the UNIX socket type. My proposed change is to add optional
columnn (:) to the UNIX socket and use it as identifier. E.g.
$s1=stream_socket_client('unix:////var/run/unix.sock:id1', $errno, $errstr,
3, STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT);
$s2=stream_socket_client('unix:////var/run/unix.sock:id2', $errno, $errstr,
3, STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT);
Part before column is used as socket path name, path after columnt - as
connection id.
Test script:
---------------
<?php
$sock = stream_socket_client('unix:////var/run/unix.sock:234', $errno,
$errstr, 3, STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT);
if($errno) echo $errstr."\n";
$sock2 = stream_socket_client('unix:////var/run/unix.sock:123', $errno,
$errstr, 3, STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT);
if($errno) echo $errstr."\n";
// here we can use "netstat -an|grep unix.sock" to control number of
established connections
sleep(1000));
?>
Expected result:
----------------
no connection errors and 2 different connections
Actual result:
--------------
connection error
