[M] Change in osmo-ci[master]: jobs/update-osmo-python-on-slaves: remove

by osmith

osmith has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-ci/+/37549?usp=email ) Change subject: jobs/update-osmo-python-on-slaves: remove ...................................................................... jobs/update-osmo-python-on-slaves: remove This job should not be needed anymore, as the builds of almost all jenkins jobs are done in docker where we install osmo-python-tests inside the containers if it is needed. We already removed the initial deployment to jenkins nodes via ansible in I7c87bd516d1bcdbcc21f65909dabbd3ccc38eede ("ansible: osmocom_build_deps: remove"), let's remove the job that updates osmo-python-tests too. I'm doing this now because the jenkins job started failing after I42ba71e2fd0ceb8466758ea46e9ae33e3d4fcb91 ("contrib/jenkins.sh: use virtualenv and pip") on some nodes where virtualenv is not available. The contrib/jenkins.sh script was used for both CI verification and to actually deploy this python package to the jenkins nodes, which was not really obvious and also as noted above isn't needed anymore.

[S] Change in osmo-pcu[master]: pcuif_sock: do not retry when sending PCU version

by dexter

Attention is currently required from: fixeria, pespin. Hello Jenkins Builder, fixeria, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-pcu/+/37548?usp=email to look at the new patch set (#2). The following approvals got outdated and were removed: Code-Review-1 by fixeria, Code-Review-1 by pespin, Verified+1 by Jenkins Builder Change subject: pcuif_sock: do not retry when sending PCU version ...................................................................... pcuif_sock: do not retry when sending PCU version When some client connects to the PCU socket, the PCU sends a TXT indication with its version number in it. There is a retry mechanism in place that checks if the BTS got active. In case the BTS is not active yet, the TXT indication with the version number is repeated. This mechanism is unnecessary. It even can cause annoyance in cas the BTS on the other end does not send an info indication because it does not use GPRS/EGPRS at all. The TXT indication is sent after the PCU socket connection is made. We use a normal unix domain socket, which can not lose messages. It is guaranteed that the TXT indication reaches the client (BTS or BSC).
