If you do read my previous email you will understand what I meant. This
new stuff looks like quick hack to fix just few demands, whilst a
discussion about such major change (done in the last minute) would
reveal a better design and approach. openser is now beyond one man
interests, and as you talk about collective work and collaboration, what
happened it is not the right approach.
I do understand all the code, and really don't like the solution. What
it brings:
- for internally generated messages we can now: do xlog, add headers,
benchmarking, avpops and accounting
The new route is executed after the buffer with the message (that was
previously sent to the network) is built, reparsed in a local static
sip_msg structure, and then apply eventually new changes induced from
local_route, building a new buffer and sending. No real connection to
TM, just that the function to send such message is there -- no
possibility to bind to transaction callbacks, or other stuff specific to TM.
Same, but more will be available if it is going to be plugged in the
core, for all messages. Self generated messages are easy to detect, by
that we can select the ones that are processed with the current version.
More over:
- siptrace can be easily updated to avoid tm callbacks and use this new
route for outgoing messages, and it will work even for stateless mode
- the destination ip/port/protocol can be made availabe in just few
lines of code, allowing flexible filtering and accounting (there is a
pending feature request IIRC)
- details from sent buffer may be accounted
- the self generated CANCELs can be handled as well.
Just some that got in my mind.

You mean about the C code or? Nobody claimed current code is wrongly
written, just it is not the proper solution for project's demands.
Cheers,
