Hi,
I'm developing a custom stream wrapper and I've found this bug
implementing the stream_seek() method.
My php version:
PHP 5.2.8 (cli) (built: Dec 17 2008 00:54:27)
Copyright (c) 1997-2008 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies
with Zend Extension Manager v1.0.11, Copyright (c) 2003-2006, by
Zend Technologies
with Zend Optimizer v3.2.0, Copyright (c) 1998-2006, by Zend
Technologies
with Zend Debugger v5.2.2, Copyright (c) 1999-2006, by Zend Technologies
I've attached a simple script to reproduce the bug. It's a modified
version of the example stream wrapper at
http://www.php.net/manual/en/stream.streamwrapper.example-1.php.
Expected result should be:
whence=0
whence=1
whence=0
line1
line2
line3
but it is:
whence=0
whence=0
whence=0
line1
line2
line3
It seems that the SEEK_CUR parameter is always ignored and the whence
value passed to my wrapper is SEEK_SET.
Using SEEK_END works as expected.
Regards,
Davide Romanini

I think (didn't verify) that PHP keeps track of the position and
rewrites CUR to SET accordingly, but as said: Didn't verify.

I'll take time to try the script on php 5.2.11. I tried also on php 5.2.6
without zend extensions without success. If someone on the list could try
it on a php 5.2.11 sandbox it is very welcome :-)

Well, and why the hell php should do that?? It is a bug to me.
