Is there a common way to identify

--changed-since

on

main

branches after a PR is merged? For example, with this workflow: 1. A PR is opened, we can use

--changed-since=origin/main

to detect everything that's new on the PR. 2. The PR is merged to

main

. We want to run a command with effectively the same files that "changed-since" on the PR, but we can't use

origin/main

anymore. A few thoughts in the 🧵

also, depending on the CI system used, there’s usually some env var or so that points to the “last successfull” build..

I'm on CircleCI. I don't recall seeing this in the past, but I can look to see - that's a good idea.

was hoping for an easier answer, like for Jenkins, there’s a env var from the git plugin providing this in the env directly.. but as long as it’s doable 😉

I ended up recreating this with git tags on my own - just linking these threads together: https://pantsbuild.slack.com/archives/C046T6T9U/p1675956171363579?thread_ts=1675801304.389179&cid=C046T6T9U
