Description:
------------
When writing data to a socket, the program fails when writing more than
8192 bytes, irrespective of a given buffersize.
Specifics:
- Windows 2000
- 5.0.0.0 RC1-dev (-200403101130)
- Command line interface (using cygwin)
- Almost no modules, just php_sockets.dll
- Default php.ini(-dist), apart from
E_ALL for the error logging
Note:
The socket shouldn't be blocking, I didn't ask for it, and
set_stream_blocking(true) doesn't change it; I'm guessing this is some
irrelevant (for me) implementation detail for PHP.
Note:
Writing to localhost does work.
Note:
Writing less than 8192 bytes does work (well, didn't check the exact
size where failure starts to happen).
Note:
No problems on my Linux box and PHP 5.*.
Reproduce code:
---------------
<?php
$socket = fsockopen('some-other-host', 80, $errno, $errmessage);
$message_body = '';
for ($i = 0; $i < 4000; $i++) $message_body .= 'yadda ';
$contentlength = strlen($message_body);
$message = "POST / HTTP/1.0\r\n";
$message .= "Host: some-other-host\r\n";
$message .= "Content-Type: text/plain\r\n";
$message .= "Content-Length: $contentlength\r\n";
$message .= "\r\n";
$message .= $message_body;
fwrite($socket, $message);
fclose($socket);
print($errmessage);
print("Done\n");
?>
Expected result:
----------------
Expecting to just see "Done"
Actual result:
--------------
JeroenP@geneva$ bin/php fwrite-bug.php
Notice: fwrite(): send of 8192 bytes failed with errno=0 A non-blocking
socket o
peration could not be completed immediately.
in C:\home\wwwroot\aria\fwrite-bug.php on line 12
Done
