I also have a question. The majority of my deployments are config changes, not backports – can scap backport deploy those as well? I wouldn’t assume so based on the name, but Tyler’s email mentions operations/mediawiki-config…

Hi Martin, thanks for the feedback!

I often +2 all backports at the start of the window (or even prior the window), because I want to save time. It enables me to deploy more patches than I would be able to deploy with scap backport +2'ing it each patch separately. I also parallelize some of the steps (such as, +2'ing a config patch during the sync step), which also saves a bit of time. How would I do this with scap backport? By +2'ing the patch manually, and then letting scap backport figure out its magic?

Yes, you can do a +2 ahead of time and still use scap backport to do the remainder of the process, just be aware that if you do this and a patch ends up getting merged before the patch you are in the process of backporting with scap backport gets merged, then scap backport would end up syncing both patches at the same time (you will be given a warning and asked if you want to proceed).

Also, I'd like to mention that many ordinary deployments currently require a script to run. How would that work in scap backport world? When it asks me for confirmation, I will wait, run the script, and then finish it, to ensure the script runs at the right time

Good question...Do you mean the confirmation after syncing to debug servers? I assume you'd need to run the scripts right after pulling the changes to the deploy server. If so we would need to add an additional step.

tl;dr: use `scap backport <gerrit url>` to deploy MediaWiki backports

____

There’s now a single step to deploy changes to Wikimedia’s production MediaWiki.

🤯 An 85% reduction in command remembering!

On the deployment host run:

    scap backport <gerrit url>

This works for any change to a live branch for mediawiki/core, extensions, skins, or operations/mediawiki-config.

More details (and a demo) inside Jeena Huneidi’s excellent write up.
