Gerrit 2.13 Upgrade¶
We will upgrade our current Gerrit 2.11 production instance to 2.13.
Our production Gerrit server is two minor releases behind the latest release of Gerrit. We want to update gerrit from 2.11.4 to 2.13.x so that we can get the latest features and bug fixes. Also we don’t want to fall to far behind upstream otherwise it might be more difficult to upgrade later.
Upgrade to Gerrit 2.13 in a maintenance window.
1. Stay on 2.11. and go without useful new fixes/features. Pros: We know the issues with this release. Cons: We are behind upstream and don’t get many new features.
2. Upgrade to 2.12.x Many companies have already upgraded to 2.12.x which makes this a viable option. Pros: Other companies have vetted this version. Cons: Fixes might be difficult to get into this branch.
3. Upgrade to master Pros: May get fixes faster on master than on stable branches Cons: Only Google and GerritForge is on master.
2.13.x has not been installed by many companies so it really hasn’t been vetted by other companies yet.
- Primary assignee:
Use Gerrit topic “gerrit-upgrade” for all patches related to this spec.
git-review -t gerrit-upgrade
We don’t have a zuul dev environemnt that uses review-dev. Currently zuul-dev.o.o does not run jobs for review-dev.o.o. The first step is to update zuul-dev.o.o to simulate production zuul. We need to update it to the same version and get it to run jobs triggered off of the gerrit stream events. Once that happens we’ll have a valid dev environment for testing Gerrit 2.13. There’s more on testing gerrit in the testing section.
In case we need to rollback, we should create a mysql database rollback script.
Create a fork from Gerrit stable-2.13 branch and add build jobs for 2.13 and it’s associated plugins.
Puppet up some changes to swap out new versions.
Create an ‘openstack/2.13.1’ fork from the latest Gerrit 2.13.x tag
We need to update review-dev.o.o with Gerrit 2.13 and test the following integrations:
- data migration
- gerrit replication
- jeepyb integration
- zuul integration
- storyboard integration (its-storyboard plugin)
- launchpad integration
- javamelody plugin
- gerrit hooks
