[sr-dev] sip_msg changes - proposal

Hello,

some months ago (iirc) we had a discussion about the sip_msg structure and the fact that it has too many header hooks, some for pretty uncommon or not really used inside sip router code.

I spotted - subject - accept_language - content_disposition - accept_disposition - unsupported - organization - diversion (expired draft?)

The list can continue a bit ... I was thinking to replace them with a call of get_hdr_by_name|type() kind of function. The benefit will be lower structure.

On the other hand, I would add a new field to hold the pid of the process that received the message. There are some potential races by using only id to identify a message, especially in serial forking.

Opinions?

Daniel
