Bug #4709
closedosmo-bts-trx (latest version 1.2.1) crashes in ttcn3-bts-test-latest
0%
Description
Looking at the build artifacts of https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-bts-test-latest/, I noticed that almost all of them (at least since build#647, Jul 15, 2020) contain cordumps of osmo-bts-trx.

Package versions:
Package: libosmocore-dev Version: 1.3.2 Package: libosmo-abis-dev Version: 0.8.1 Package: osmo-bts Version: 0.4.0-2
I assume it has been fixed in the recent master, as we don't see any coredumps in ttcn3-bts-test (master).

Hmm, both osmo-bts-trx and apt show different versions:
root@470aa7e166f4:/data# osmo-bts-trx -V OsmoBTS version 1.2.1 root@470aa7e166f4:/data# apt show osmo-bts | grep Version Version: 0.4.0-2

I wonder why there is a osmo-bts package installed at all. the package we build in obs are osmo-bts-trx and osmo-bts-virtual, see https://download.opensuse.org/repositories/network:/osmocom:/nightly/Debian_10/amd64/

In the osmo-bts-latest container here:
root@077a826bddb4:/data# dpkg -l | grep osmo-bts ii osmo-bts-trx 1.2.0 amd64 osmo-bts-trx GSM BTS with osmo-trx ii osmo-bts-virtual 1.2.0 amd64 Virtual Osmocom GSM BTS (no RF hardware; GSMTAP/UDP)
Not sure who/what installed an ancient (maybe upstream debian) package on the container/system you reference?

if this only happens in latest but not in nightly, then the bug is fixed already in master. Either we have to back-port the fixes and make a patch release, or we have to tag new releases.

Turns out it's my fault: 'osmo-bts' is an ancient package provided by Debian itself, while in the Dockerfile we actually install 'osmo-bts-trx'.

I should have used dpkg to check versions of the installed packages, not apt (such a mess).

So after all mess is resolved, what's the current status of this tickets? Is there still an issue? any proposed solution?

I just checked ttcn3-bts-latest, and magically osmo-bts does not crash anymore. Last build where the artifacts contain a coredump is 677: https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-bts-test-latest/677/artifact/logs/bts/.
