Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Pull requests with cancelled, timed-out, or action-required compatibility checks may be labeled as requiring a release bump even when no binary incompatibility was found. Exclude these non-failure conclusions before merging so release labeling remains accurate. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

💡 Result:
The terms check-failure, check-cancelled, check-timed-out, and action_required are status descriptors used in automated pull request management tools, most notably Mergify [1]. These attributes are used within configuration files to define conditions for workflows, such as automatic merging or blocking pull requests based on the status of CI/CD checks [1]. Mergify specifically defines these as follows: check-failure: This attribute matches checks that have failed [1]. Notably, for backward compatibility and to ensure robust rule evaluation, this category also includes checks that report as cancelled, timed out, or action required [1]. check-cancelled: This attribute matches checks that have a cancelled conclusion, such as a GitHub Actions job stopped by a concurrency group [1]. While these are also captured under check-failure, using check-cancelled allows you to isolate or ignore cancellations in your logic [1]. check-timed-out: This attribute matches checks that have timed out during execution [1]. action_required: This refers to a state where a check is paused and awaiting external intervention or manual approval to proceed [1]. Because check-failure is a broad category that encompasses other non-success states, it is common practice to combine these attributes with negation operators to create precise rules [1]. For example, to trigger a rule only on a genuine failure while ignoring a cancellation, one might use the following configuration logic [1]: # Match a genuine failure but ignore a cancellation - check-failure = test - -check-cancelled = test

💡 Result:
In Mergify configuration, the conditions check-failure, check-cancelled, check-timed-out, and action-required (often handled as a subset of failures) are attributes used to match the status of checks on a pull request [1][2]. These attributes take a list of strings representing the check names [1][2]. Key characteristics include: - check-failure: Matches checks that have failed [1][2]. For backward compatibility, this also includes checks that report being cancelled, timed out, or requiring action [1][2]. - check-cancelled: Specifically matches checks that report a "cancelled" conclusion, such as those stopped by GitHub Actions concurrency: cancel-in-progress [1][3]. - check-timed-out: Specifically matches checks that reported a "timed out" conclusion [1][2]. - Addressing specific states: Because check-failure includes other states by default, you can isolate specific outcomes by pairing the conditions [1]. For example, to match a genuine failure while excluding a cancellation, you can use: - check-failure = - -check-cancelled = [1][2] The qualified form is supported for these attributes, allowing you to check them against specific statuses across your workflows [1][2]. Note that while Mergify provides these conditions to evaluate pull requests, distinct mechanisms like checks_timeout in queue_rules manage how the Merge Queue handles checks that do not report back in time [4][5].

Exclude non-failure conclusions from the release label rule.
At line 16, check-failure also matches cancelled, timed_out, and action_required. A cancelled or timed-out test / binary-compatibility run can therefore add release-bump-needed without reporting a binary incompatibility. (docs.mergify.com)

I am not sure, if this will work as you dream it should...
I imagine that we'd like to (theory):
But what we get is (practice):
Neither here nor in evolution-gaming/scala-github-actions#20 I find a machinery to mark reliably the PR as "binary incompatible" in a way, which would limit the Idea is nice, but I am afraid that execution relies on Developer's actions (or lack of them) more than on actual checks. We are not publishing new release from GitHub where we would see all merged PRs and their labels. We publish by pushing the tag and then letting To clearly prohibit patch/minor release when minor/major is due, we have to have external tools, which relies on external config, outside the repo, but with weak MiMa checks for Scala code and way how I do not believe, that this is a clear way on how to proceed. |

Trying the rules here before they go into the shared config. A pull request that keeps binary compatibility gets non-breaking-change, one that breaks it gets release-bump-needed, both driven off the test / binary-compatibility checks and cleared again by toggle.
Shared version is evolution-gaming/scala-github-actions#20, to be merged once this proves out.
