Description

All test cases fail under both Debian and CentOS:

https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-sip-test/1051/
https://jenkins.osmocom.org/jenkins/view/TTCN3-centos/job/TTCN3-centos-sip-test/238/

Although, the 'latest' is relatively stable:

https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-sip-test-latest/828/

I spent a few hours trying to investigate what's going on. Here are some intermediate results:

The test cases fail due to DTEs listed below:

  • "MNCC_CodecPort.ttcn:19 Dynamic test case error: Initializing a variable of enumerated type @MNCC_Types.MNCC_MsgType with invalid numeric value 346140544. (No such file or directory)"
  • "Dynamic test case error: SIP Test Port: syntax error "v" -> unexpected character at character position 1."
  • "MNCC_Emulation.ttcn:348 Dynamic test case error: Write error (Broken pipe)"

Sometimes it's one reason, sometimes another. Sometimes there is no DTE but "timeout of Tguard". Weird.

I constantly see the following error in the output of osmo-sip-connector:

ttcn3-sip-test-latest doesn't fail probably because it's still using MNCCv6, while master uses MNCCv7.

It could be some TTCN3 MNCCv7 specific issue. I added MNCCv7 support to osmo-ttcn3-hacks.git in 563b3d013b166115a4f9e526d5e21df36f3bd399 (Sep 9 2020), not sure how it started later (JAN 16 2021).

As a result, osmo-sip-connector has been totally broken since Jan 12 2021.
