Subject: [SR-Users] Kamailio developers meeting - follow up remarks

Hello,

last week we had the 2nd annual Kamailio Developers Meeting hosted by Sipgate in \
Dusseldorf, Germany:

  * https://www.kamailio.org/w/developers-meeting/

16 people were at the event in various roles.

Giacomo Vacca published on his blog a good summary of what happened there:

  *
https://www.giacomovacca.com/2019/11/my-notes-on-kamailio-developer-meeting.html

This year we had a lot of discussions, as well as work done on multiple planes, not \
only Kamailio code. So I am trying to list here some of the conclusions for future \
development, the technical aspects of the meeting, so everyone is aware and can \
provide feedback.

1) Effective work was done on:

  * kamailio code
  * kamailio rpm packaging
  * kamailio tools (kamctl)
  * kamailio release process
  * kamailio project keys (to be used to sign the packages)

2) Documentation

2.a) Wiki

  * it was somehow a rough consensus to move the wiki content to github, along with \
changing the format from dokuwiki markdown to the standard/github markdown. This \
should enable people to make pull requests so developers or community members can \
review and aprove new content. It also makes it easier to contribute using existing \
github account, now the kamailio.org/wiki is requiring to make a dedicated account, \
which many prefer not to do it.

  * the presentation can be done either by using mkdocs to generate html files hosted \
on kamailio.org or using the github provided wiki portal.

 2.b) Docs for variables and transformations

  * there was a proposal to move them in the documentation the modules that export \
them, there are pros and cons, needs more discussions. Now they are in the wiki, so \
this probably has to resume after deciding on 2.a).

3) Kamailio Modules

3.a) replication (dmq) - several participants discussed about negotiations between \
nodes to take active role on some cases (e.g., active dialogs)

3.b) api integration - quite some interest in JSON-based API routing, concluding in \
extending rtjson to cover more use cases

3.c) security - have options to restrict the use of TLS1.3 or newer

4) Kamailio Releases

  * v5.3.2 was released during the event, allowing to document the process
  * work to automatize the process is planned, then eventually assing teams for \
takeing cares of releases from specific branches

5) Kamailio Testing

  * existing docker-based testing framework should be extended and integrated in \
CD/CI pipeline

6) Kamailio packages

6.a) rpms

  * rpm.kamailio.org has been prepared and is expected to take over the opensuse \
build service for building rpms and hosting them. Expected to provide support for \
hosting many kamailio versions in the same release series so one can do downgrade to \
older releases. Also, there is work in progress to provide nightly builds.

6.b) debs

  * work is planned to offer many kamailio versions in the same release series

7) Kamailio tools

  * kamctl/kamdbctl should be obsoleted in favor of kamcli, which offers a better \
framework for input validation and output formatting, as well as better portability, \
no longer depending on shell interpreter

8) Various discussions

  * kemi exports from C point of view and how to combine the documentation for \
                modules and their kemi exports
  * how to make kamaiio friendlier in virtualized environments (ended up in the need \
                of making the use of advertised address a bit more dynamic)
  * project organizatoric topics - to be approached separately
  * next events - Fosdem - someone should submit a proposal to present about Kamailio

9) Long term goals

We speak here more or less about Kamailio 6.0 ...

  * change the behaviour of the native config interpreter to be consistent with the \
other programming languages in terms of handling the response code (change what is \
now: the evaluation of negative value to false and positive value to true and the \
hidden return 0 to exit)

  * make the pool of processes more generic, so they can handle traffic from more \
sockets (being sip traffic or something else) -- this should make better use of \
resources, as some sockets might be less busy that others

I hope I covered the important topics, if I remember something else, I will reply on \
this thread. Or maybe other participants can contribute missing topics.

Should anyone have comments or suggestions on the above topics, or new ones, let's \
discuss on sr-users because it impacts the long term use of Kamailio (sr-dev is cc-ed \
now for notification purposes).

Overall, there were 2 very intensive days, however in a friendly and relaxed \
environment offered by Sipgate. Extremely useful discussions, not only about \
Kamailio, but about RTC ecosystem. At the evening social network event event, a \
couple of external people joined, some of them presenting very interesting use cases \
of Kamailio.

Many thanks to all participants that allocated time and resources to come to \
Dusseldorf, as well as to the companies that covered expenses for participants.

Cheers,
Daniel
