From: Johannes Schindelin <johannes.schindelin@xxxxxx> Whenever a branch is pushed to a repository which has GitHub Actions enabled, a bunch of new workflow runs are started. We sometimes see contributors push multiple branch updates in rapid succession, which in conjunction with the impressive time swallowed by even just a single CI build frequently leads to many queued-up runs. This is particularly problematic in the case of Pull Requests where a single contributor can easily (inadvertently) prevent timely builds for other contributors. To help with this situation, let's use the `concurrency` feature of GitHub workflows, essentially canceling GitHub workflow runs that are obsoleted by more recent runs: https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#concurrency Signed-off-by: Johannes Schindelin <johannes.schindelin@xxxxxx> --- ci: avoid unnecessary builds Just something I noticed recently and only got around to implement today.
