15:30 → 15:40 CTA dev topics

Gtest build instructions for external sites

• Issue link #187
• Decide how gtest-1.12 should be installed by (or made available to) external users building CTA locally.

Consistency issue in volume names format

• Issue link #175
• We will enforce TAPE VID to be UPPERCASE. Should we apply the same to other fields?

REPACKING tape state and queue cleanup

• [Richard]: Testing of release candidate version v4.8.0-0.rc3 #83
• [Joao]: Discuss release plan

Update RetrieveJob to support completion report

• Issue link #154

Re-enabling automatic valgrind checks in branches / merge requests

• [Vova]: Discuss topic

"Needs discussion" topics

• Issues link

"Dev issue needed" topics

• Ops issues link

Gtest build instructions for external sites

• We decided that we will make the gitlab repo cta-dependencies publically available.
• Jorge will work on it. Before making it public, we need to update the README.md file with the build/install instructions and add the Licensing documentation to any relevant file.

Consistency issue in volume names format

• Joao will perform the changes that already have been discussed (VID should be uppercase). Regarding the uppercase constraint in other fields, we will for Vlado confirmation that they are needed or not.

REPACKING tape state and queue cleanup

• Joao will try to have the development work done before the end of next week, so that it can be tested during the following weeks.

Update RetrieveJob to support completion report

• The proposed changes have been accepted. Tigran can proceed with the implementation and submit a MR.

Re-enabling automatic valgrind checks in branches / merge requests

• Ideally, we would like to run Valgrind as the last test before merging to main (after it has been approved). Jorge will investigate will gitlab people if there is any possibility to do this.

15:40 → 15:50 AOB
