docs: clarify license return warnings by frostebite · Pull Request #591 · game-ci/documentation

frostebite · 2026-09-30T21:36:35Z

Documents the license-return failure mode accurately:\n\n- a return retry notice is not proof that a seat leaked;\n- clearing an Actions cache cannot affect Unity's server-side licensing state;\n- a normal build returns from its activating container; and\n- recovery for an unavailable or binding-changed machine is Unity ID, not a later hosted-runner return job.\n\nAlso scopes manual command-line return to a persistent self-hosted machine and notes Unity's documented Personal return flow.

Summary by CodeRabbit

Documentation
- Clarified that GameCI automatically returns activated license seats after normal build and test jobs.
- Explained when manual return may be needed, including interrupted jobs and later unavailable-seat errors. Manual return guidance distinguishes serial and named-user licenses, and notes that Personal-license users should sign out of Unity Hub.
- Added guidance on interpreting return errors, timeout retries, stale activations, and why clearing the GitHub Actions cache does not change licensing state.
- Advised against adding a separate return step for hosted runners; manual returns are documented for persistent self-hosted machines.

📝 Walkthrough

Walkthrough

The license return guidance describes automatic returns after normal build or test jobs, when manual returns may apply, and how to interpret licensing errors and stale activations.

Changes

License return guidance

Layer / File(s)	Summary
Automatic and manual license returns `docs/03-github/05-returning-a-license.mdx`	The page describes automatic returns, supported return routes, and when manual returns apply to hosted or self-hosted runners.
Licensing errors and stale activations `docs/03-github/05-returning-a-license.mdx`	The page distinguishes licensing errors from confirmed failed returns, describes timeout-only cleanup retries, and documents stale-seat recovery.

Before / after behavior

observed — Modified behavior in docs/03-github/05-returning-a-license.mdx: The documentation replaces the claim that manual return is generally unnecessary except after an unrecoverable error, and the claim that only professional licenses can be returned. It now describes automatic returns after normal builds or tests, Unity’s documented serial and named-user command-line flows, and the Personal-license sign-out route.
observed — Modified behavior in docs/03-github/05-returning-a-license.mdx: New warnings distinguish licensing messages from confirmed failed returns, state that cleanup retries only explicit licensing-client timeouts (not generic unavailable-token messages), and note that cache clearing does not affect server-side licensing state. The documented unavailable-seat recovery is releasing the stale activation in Unity ID, including when the activating machine is unavailable or its binding changed.
observed — Modified behavior in docs/03-github/05-returning-a-license.mdx: The general instruction to use the return action to free a license slot is replaced with guidance against a separate return step for hosted builds, because a new Docker container has a different machine identity. Manual return is instead described for a self-hosted runner using the same persistent machine that activated a serial license.

+hosted-runner build: a separately started Docker container has a different
+machine identity and Unity can reject its return.


🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the machine-identity claim for separate containers.

Line 34 says a separately started Docker container has a different Unity machine identity. The FAQ in docs/10-faq/index.mdx, Lines 207–218, says GameCI hardcodes machine-id in its published Docker images. The game-ci/unity-return-license@v2 action is based on a unityci/editor image. For the standard GameCI image pair, starting a second container does not imply a different machine ID. Replace this rationale with the actual limitation, or qualify it to configurations whose images use different IDs. (game.ci)

Superseded by #592, which consolidates this PR together with the other two open docs PRs (#589, #590, #591) into a single change so they can be reviewed and merged as one. The content here is carried over in full; closing in favour of #592.

Unifies #589, #590 and #591 so the documentation change can be reviewed and merged as a single unit instead of three PRs that overlap on the license-return page. - #589: build memory limits and container env var behaviour (troubleshooting) + the missing `dockerShmSize` reference entry. - #590: document the `game-ci activate` / `game-ci return-license` commands, the `unity-activate` no-auto-return caveat, and add both to the CLI command table. - #591: clarify license-return warnings - a `License return failed` message is not proof of a leaked seat, and cache clearing cannot affect Unity's server-side licensing state. The one conflict was `docs/03-github/05-returning-a-license.mdx`, which #590 and #591 both rewrote. Resolved as the union: #590's structure (auto-return for builder/test-runner, the `unity-activate` caveat, the CLI `return-license` reference, the legacy action section) combined with #591's newer guidance that Unity's documented Personal-seat recovery is signing out of Unity Hub, and its warning against a second return step on hosted runners.
