VPP RC1 Milestone Tasklist
1. At least a week prior to the RC1 date, email a reminder to vpp-dev@lists.fd.io about VPP RC1 Milestone. See an example email or another example email.
2. Resend reminder a day or two prior to the RC1 date.
Pulling a VPP Throttle Branch
NOTE: Steps 3 and 4 can be done any time prior to RC1 branch day. At the very least, discuss the requirements with the individuals ahead of time to set the correct expectations.
3. Request LF Admin (via fd.io helpdesk) create Nexus repositories
Have LF admin staff create in nexus new repositories of the form "fd.io.${branchpart}.${distropart}" where branchpart is of the form stable.YYMM (example stable.1804) and the distropart is one of the supported distributions.
At the current time (circa 19.04), we currently support the ubuntu.xenial.main, ubuntu.bionic.main, ubuntu-arm.bionic.main, and centos7 distributions. NOTE: The Nexus package manager has problems with bionic packages, thus while the build infrastructure still uploads packages to nexus.fd.io as well as packagecloud.io, the Installing VPP Binaries from Packages refer solely to packagecloud.io, thus validation of the nexus packages (other than bionic packages) is recommended, but not strictly necessary.
For example:
Hello fd.io helpdesk! Could you create the Nexus repositories required for the VPP 19.04 release, please? Per https://wiki.fd.io/view/VPP/CommitterTasks/PullThrottleBranch these should be named: fd.io.stable.1904.ubuntu.xenial.main fd.io.stable.1904.ubuntu-arm.bionic.main fd.io.stable.1904.ubuntu.bionic.main fd.io.stable.1904.centos7 Note that the centos repository should be setup as a Yum repository, to enable the task that generates the index files. Please also run the indexing task manually to generate an empty index. Thanks, <name>
NOTE: In the message to the helpdesk we indicate that the Centos repository is also a Yum repository and needs the indexing task setup. If this is not done then the Centos merge job will fail with a message in the console output that Yum could not retrieve that index.
4. Request Ed Warnicke create the package cloud repos.
Send and email to Ed Warnicke (eaw@cisco.com and/or hagbard@gmail.com) reminding him to create the package cloud repositories for the new release and remind him to ensure that all of the platform repo's contain at least one package. If lets say, the bionic repo does not contain any packages, then the build will fail in a non-intuitive manner that may require a day's worth of troubleshooting to resolve.
NOTE: If these do not exist or the permissions for them are wrong, then the merge jobs will fail after uploading build artifacts to nexus.fd.io
5. Jenkins: (can be done and merged some days before the date of pulling the branch) - In the ci-management Git repo, edit jjb/vpp/vpp.yaml:
- a. https://git.fd.io/ci-management/tree/jjb/vpp/vpp.yaml#n49
- add a new 'stream' for your new YYMM. Example for stable/1801:
- '1801':
branch: 'stable/1801’'
repo-stream-part: 'stable.1801'
- b. https://git.fd.io/ci-management/tree/jjb/vpp/vpp.yaml#n87
- likewise add a new stream here. Exactly the same idea as the previous step.
- c. Example: https://gerrit.fd.io/r/9934/
6. Create a new branch stable/YYMM (example: stable/1801) in the Gerrit web UI against the point on master you wish to be cutting the branch (usually HEAD at the time you’re cutting).
7. On stable/YYMM (example: stable/1801) prepare a commit which updates the .gitreview to reflect the correct branch
- b. Merge patch onto the new stable branch
NOTE: Verify that this patch is in fact on the new stable branch, and not on master!
8. Lay down a tag (v18.01-rc1) on stable/1801 at the point of the patch you just merged.
9. Verify that the nexus repos have packages with the correct version and are working
- a. Remerge the patch from step 7
- b. When the remerge from step 7 is complete, verify that the correct package versions have been uploaded onto the nexus server
https://nexus.fd.io/content/repositories/fd.io.stable.YYMM.centos7/
https://nexus.fd.io/content/repositories/fd.io.stable.YYMM.ubuntu.xenial.main/
- c. Examples
- d. Verify that package like artifacts are present in all the above git repos by looking for:
- Non-zero sized ‘Package’ in the apt repos (xenial)
- A repodata/ subdir in the yum repo (centos7)
- e. Update the Installing VPP Binaries from Packages Wiki page with instructions for the new branch, and test that you can install packages
10. Lay down a tag for the next release RC0 (e.g. 1804-rc0) on master.
11. Update the package version used by Java generation on master with the next release version in vpp/src/configure.ac
- a. Example: https://gerrit.fd.io/r/#/c/8578/
- b. Merge the patch.
12. Verify that the nexus repos have packages with the correct version and are working
- a. Remerge the last merged patch on master
- b. When the remerge of the last patch on master is complete, go look for package with the correct versions at:
- c. Verify that package like artifacts are present in all the above git repos by looking for:
- Non-zero sized ‘Package’ in the apt repos (xenial)
- A repodata/ subdir in the yum repo (for centos7)
- d. Follow instructions on VPP/Installing_VPP_binaries_from_packages and verify that packages with the new versions are installed
13. If the Jira steps from VPP/CommitterTasks/ApiFreeze#Jira_versions didn't happen yet, do them now.
14. Send the all-clear message. Example.
Amend as necessary with any caveats; for example the 1804 RC1 milestone opened master and stable on different days while minor issues were resolved.
