Change in libosmo-abis[master]: input/ipaccess: Avoid extra poll() call when e1i_ts tx queue becomes ...

by pespin

Instead, let's disable it immediatelly at the time we submit the last message in the queue.

Change in osmo-ci[master]: jobs: TTCN3-centos: set OSMOCOM_REPO_TESTSUITE_MIRROR

by osmith

osmith has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-ci/+/28100 ) Change subject: jobs: TTCN3-centos: set OSMOCOM_REPO_TESTSUITE_MIRROR ...................................................................... jobs: TTCN3-centos: set OSMOCOM_REPO_TESTSUITE_MIRROR In previous patch Id114d55edc2ba92f7851243ab7df51db332079c4, only the OSMOCOM_REPO_MIRROR should have been overridden. However OSMOCOM_REPO_TESTSUITE_MIRROR defaults to OSMOCOM_REPO_MIRROR, so explicitly set it in this patch to the opensuse mirror. This fixes problems while building debian-bullseye-titan caused by the different directory structure of both mirrors, and OSMOCOM_REPO_PATH intentionally not taken into account while building the testsuite docker image. This is part 2/2 of fixing TTCN3-centos-bts-test, which has been failing since OSMOCOM_REPO_MIRROR was changed in osmo-ci.git. Part 1 is in docker-playground I78e0445a1b82e5cd72ecaa86e8fe25516b19f485.
