Status: Open
Bug Type: Streams related
Operating System: win32 only
PHP Version: 5.2.8
New Comment:
Using the test above I get:
array(4) { ["type"]=> int(8) ["message"]=> string(112) "fwrite():
send of 1 bytes failed with errno=10054 Eine vorhandene Verbindung wurde
vom Remotehost geschlossen. "
So the bug is still there, I think. pfsockopen should transparently
check the socket error code and allocate a new connection if the
previous persistent connection has an error.
I have tested this on Win XP and PHP 5.2.11 download.

hi
please refer to bug #49447 (http://bugs.php.net/bug.php?id=49447)
where I have attempted to resolve this issue.
i am not sure, if you tried with php 5.2.11 or with recent snapshot
and let me know if this resolved your issue

Here's a test case:
----------------- TestServer.java ------------------
import java.io.InputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;
public class TestServer {
public static void main(String args[]) throws Exception {
ServerSocket ss = new ServerSocket (9090);
System.out.println("accepting connections");
Socket s = ss.accept();
System.out.println("got initial request");
InputStream in = s.getInputStream();
OutputStream out = s.getOutputStream();
while (true) {
out.write((byte)in.read());
out.flush();
System.out.println("waiting for next request");
}
}
}
---------TestClient.php--------------
<?php
function dieWithMsg() {
var_dump(error_get_last());
exit(1);
}
$errno = null; $errstr = null;
$conn = pfsockopen("127.0.0.1", 9090, $errno, $errstr, 30) or
dieWithMsg();
fwrite($conn, "\0") or dieWithMsg();
fread($conn, 1) or dieWithMsg();
echo "done";
exit(0);
?>
------------------------------------
To reproduce this bug on Windows XP and above, start the server with:
java TestServer
and refresh the
http://127.0.0.1/TestClient.php
a few times.
Then stop TestServer and start it again.
Refresh
http://127.0.0.1/TestClient.php
to get a broken connection from PHP.
I was able to reproduce this bug with yesterday's 5.2 windows
snapshot.

I changed the EGAIN to EWOULDBLOCK in the checking.

The windows equivalent to EAGAIN is EWOULDBLOCK or WSAEWOULDBLOCK.
Could it be that EAGAIN is 0 on windows?
Unfortunately I don't have the time and resources to debug this at the
moment.

Well, the initialization is okay now.
However, the code still doesn't work on windows. Which means that
there's another bug.
The php_socket_errno() != EAGAIN looks suspicious.
"Depending on whether your socket is blocking or non-blocking, you
either get FD_CLOSE notification, or recv() returns 0 (graceful
disconnection), or recv() returns WSAECONNRESET error."
I don' see how the current code handles these three cases properly.
