Summary: 0002060: fseek() not supported on a socket stream
Description: PHP's fseek() is supposed to be able to discard data on a socket. Test case part 1, run on command line to set up a listen socket that will spew out some data when you connect to it:

$ echo "1234567890" | nc -l -p 8000

Test case part 2:

<?php
$sock = fsockopen("127.0.0.1", "8000");
fseek($sock, 5, SEEK_CUR);
print fgets($sock);

Vanilla PHP prints "67890". Quercus throws an exception:

java.lang.UnsupportedOperationException: com.caucho.vfs.SocketStream

This test case generates the following stack trace:

java.lang.UnsupportedOperationException: com.caucho.vfs.SocketStream
        at com.caucho.vfs.StreamImpl.seekStart(StreamImpl.java:232)

Attached is php/1m0p.qa, a rough draft regression test for this issue.

This specific issue is now fixed.

php/1m0p.qa

Still, a couple of edge cases related to fread and ftell
on sockets remain.

Added php/1m0q.qa, fseek now skipps over buffered bytes
when doing a seek forward.
