fix: clearer licensing messages, and retry transient failures from one place - #292
Merged
Merged
Conversation
The message printed when Unity refuses the account-only Personal route had grown to fourteen lines: it explained our grading history, cited a workflow file by path, and justified a conclusion about a Unity version. That is written for the maintainer who argued about it, not for the person whose build just went red. It now says what happened, rules out the two things it is not, and lists the three things that actually help - re-run, set UNITY_SERIAL, or use 2022.3 or newer - in seven lines. No repository internals, no version verdict. The assertions that pinned the old wording are replaced by ones that pin the new constraints instead: it must not claim the version is unsupported, must not cite a file in this repository, and must stay short enough to read in a build log. A length bound is an odd thing to assert, so it is written as one deliberately - the failure mode here is the message growing back, and nothing else in the suite would notice. ubuntu and mac stay byte-identical.

Every licensing call already retried, but the policy was copied into every
loop that needed it: thirty-odd near-identical messages across two languages
and four platforms, each with its own variable names, and the backoff base a
bare `= 20` literal per file. So the wording could not be changed once, the
delay could not be tuned at all, and a retry was announced with a plain print
that disappears into a build log unless you already know to look.
Two shared functions now own both halves - unity_license_retry_delay /
unity_license_retry_notice in the bash helper, Get-UnityLicenseRetryDelay /
Write-UnityLicenseRetryNotice in the PowerShell one. All 33 call sites across
ubuntu, mac and both Windows script sets go through them.
Three things this changes for a user:
- The notice is a ::warning::, so it reaches the Actions UI rather than
sitting thousands of lines into the log. Retrying is a decision the tool
makes on their behalf; a run that silently retries for five minutes and
then succeeds should not look like a run that was never in trouble.
- It says what is happening and whose problem it is not: what was being
done, which attempt this is, and that a Unity-side blip - not the user's
project or credentials - is the usual cause.
- The window is tunable via UNITY_LICENSE_RETRY_DELAY_SECONDS without
editing anything, and the default is now five attempts rather than four.
The backoff doubles, so that is the difference between a ~2.5 minute
window and a ~5 minute one, and the failures this retries on have
outlasted the shorter of those. Still bounded, and still only for the
known-transient signatures - a genuinely broken license still fails on the
first attempt.
The suite covers the mechanism on both sides: a transient failure that clears
on the second attempt ends in success, the annotation names the attempt and
the reason, no retry is announced when there is no attempt left, and the delay
doubles and honours the override. The existing assertions that pinned the old
wording are pointed at the new one - left as they were they would have passed
vacuously, which is worse than failing.

changed the title
The shell scripts' `${UNITY_LICENSE_RETRY_MAX_ATTEMPTS:-5}` is only a fallback.
The CLI sets that variable from `--licenseRetryMaxAttempts`, so raising the
shell default changed nothing for a real run - confirmed in CI, where the new
retry notice printed "attempt 1 of 4" after the shell default had moved to 5.
The default that governs is the one in src/command-options/unity-options.ts,
and it is now 5 there too. Its help text also names the doubling backoff and
the window that comes out of it, so the number is not just a bare count.
Caught by reading the retry annotation the previous commit added, which is a
reasonable argument for having added it.

The 2020.3.49f1/serial cell passed its own job while the aggregate gate failed the run on that same cell. A Docker Hub token request had timed out, no container ever started, and the verdict graded inconclusive - which the cell had no exit path for, so it exited 0. A green tick on a capability matrix is read as "measured, and capable", the one reading an unmeasured cell must never produce. - the cell exits 1 on inconclusive when the run is gating, and 0 with a warning when it is exploratory, which is what the gate already did - the editor image is pulled first, with the same retry-and-say-so shape the licence steps use, because a registry blip is what produces most of these - the permanent form of that failure, a tag that does not exist, is not retried and not reported as a temporary problem it is not The image reference is resolved by asking the CLI rather than by rebuilding the tag, so the rules in runner-image-tag.ts keep one home.

The reference the probe resolves is only the tag the run asks for on the ubuntu runner this matrix uses. Off it the pull fails, warns and the CLI pulls what it wants, so the assumption costs nothing - but it should not take reading runner-image-tag.ts to find out why "linux" is written there.

CodeRabbit caught that the new retry assertions were grading the parent environment rather than the scripts. Both holes were real: - Clear-LicenseEnv in the PowerShell suite did not clear UNITY_LICENSE_RETRY_DELAY_SECONDS, so an exported value changed what the baseline delay assertions saw - measured, and three of them fail under one. The retry knobs now go through the same list the credentials do, which also means the Clear-LicenseEnv after the tunability case actually undoes the value that case set. - run_step in the bash suite isolated credentials and the branch selectors but not the retry knobs, so the doubling assertion read the environment. They are cleared there too, and the assertion sets a hostile value on the call so it fails if that clearing is ever removed. The probe suite gets the same treatment for LICENSING_PROBE_PULL_ATTEMPTS, unset rather than assigned: the two- and three-pull cases therefore still pin the shipped default instead of tracking whatever the caller exported. Each of these was verified by removing the isolation and watching the assertion fail - 56 instead of 160, 9 pulls instead of 3, and three FAILed delay assertions - then restoring it.

What
Two changes to what a user sees and gets when Unity licensing misbehaves, both about keeping our side of the conversation simple.
1. A licensing failure now says something a user can act on
The message printed when Unity refuses the account-only Personal route on an old editor (2020.3 and earlier, whose licensing client predates
--include-personal) had grown to fourteen lines. It explained our grading history, cited.github/workflows/licensing-capability-matrix.ymlby path, and carefully justified why it was not a verdict on the Unity version. That is written for the maintainer who argued about it, not for the person whose build just went red.2. Transient licensing failures are retried from one place, and say so
Every licensing call already retried, but the policy was copied into every loop that needed it: thirty-odd near-identical messages across two languages and four platforms, each with its own variable names, and the backoff base a bare
= 20literal per file. The wording could not be changed once, the delay could not be tuned at all, and a retry was announced with a plain print that disappears into a build log unless you already know to look.Two shared functions now own both halves —
unity_license_retry_delay/unity_license_retry_noticein the bash helper,Get-UnityLicenseRetryDelay/Write-UnityLicenseRetryNoticein the PowerShell one. All 33 call sites across ubuntu, mac and both Windows script sets go through them:::warning::, so it reaches the Actions UI. Retrying is a decision the tool makes on the user's behalf, and a run that silently retries for five minutes and then succeeds should not look like a run that was never in trouble.UNITY_LICENSE_RETRY_DELAY_SECONDS(default 20s, doubling), and the default is now five attempts rather than four. The backoff doubles, so that is a ~5 minute window rather than a ~2.5 minute one, and the failures this retries on have outlasted the shorter of those. Still bounded, and still only for the known-transient signatures — a genuinely broken license still fails on the first attempt.Tests
test-licensing-verdict.shtest-licensing-probe-cell.shtest-licensing-matrix-gate.shtest-licensing-steps.shtest-licensing-steps.ps1New coverage: a transient failure that clears on the second attempt ends in success; the annotation names the attempt and the reason and says it is not the user's fault; no retry is announced when there is no attempt left; the delay doubles and honours the override. Both languages, since the PowerShell suite previously did not cover the activation routes at all.
For the probe: a failed image pull is retried and does not cost the cell, a tag that does not exist is not retried, neither writes into the log the verdict is graded from, and a cell that never reached Unity fails the job rather than passing it.
The assertions that pinned the old message and retry wording are pointed at the new text. Left alone they would have passed vacuously — the refutes would have matched nothing and reported success — which is worse than failing, and is the same class of grading error this repository keeps finding in its own licensing tests.
The message-shape assertions are deliberately about constraints rather than exact text: it must not claim the version is unsupported, must not cite a file in this repository, and must stay short enough to read in a build log.
Notes
dist/changed, sosrc/generated/embedded-assets.tsis regenerated. ubuntu and mac stay byte-identical.licensing_method.ps1for the container set,steps/resolve_unity_path.ps1for the native one), matching how those two sets already duplicatelicensing_method.runner-image-tag.tskeeps one home.UNITY_LICENSE_RETRY_DELAY_SECONDSdecided what the baseline delay assertions saw — three of them fail under one. Each isolation was verified by removing it and watching the assertion fail.🤖 Generated with Claude Code
