[Serusers] Status of pa module in CVS HEAD?

[Hendrik Scholz]

Hi!

I just had a closer look at RFC 3265 (6.3 SUBSCRIBE Bodies) and
figured out that SUBSCRIBES may have empty bodies if the header fields
are sufficient.
SER from CVS replies with a 400 error saying 'Error while parsing headers'.

this is how a sample packet looks like:
#
U xx.xx.xx.xx:5061 -> xx.xx.xx.xx:5060
SIP/2.0 400 Bad Request.
Via: SIP/2.0/UDP xx.xx.xx.xx;branch=z9hG4bKea3f.82e1f753.0.
Via: SIP/2.0/UDP xx.xx.xx.xx;branch=0.
Via: SIP/2.0/UDP xx.xx.xx.xx:49449.

To: <sip:bbbbb at foobar.bla>;tag=95329101123423eab1637e9ad490b3a6-e941.
Call-ID: db28e67d79614e44b55275b6c6a025bd at xx.xx.xx.xx.
CSeq: 1 SUBSCRIBE.
Error while parsing headersContent-Length: 0.

The error message is misplaced from my point of view.

ser -E says:

12(24674) SUBSCRIBE from:sip:user at foobar.bla to:sip:bbbb at foobar.bla 
ruri:sip:bbbbb at foobar.bla messageid:3
12(24674) handle_subscription() entered
12(24674) parse_hfs(): Error while parsing headers
12(24674) handle_subscription(): Error while parsing message header
12(24674) handle_subscription about to send_reply and return -2

I cannot get my clients using 'application/xpidf+xml' to successfully
exchange presence information mainly due to the fact that SER doesn't
seem to take care of it:

11(24673) SUBSCRIBE from:sip:bbbb at foobar.bla to:sip:user at foobar.bla

What's the status on presence?
I've got a bunch of small patches that fix some minor problems but 
wonder if it makes sense to send them upstream.
Anybody running presence on CVS HEAD?

Thanks,
   Hendrik
