It runs 14 legs: seven on `windows-2022` and seven on `windows-2025`. Each leg installs a real released build with that build's own scripts, then runs this commit's install or upgrade script over it. The legs cover four shapes: +- U1: an install on the default virtual account. +- U2: an install whose service logon was changed to a non-default local account. +- U3: an install whose service was deleted. +- U4: a pre-3.9 folder directly under `C:\` that must still refuse and print the move steps. + +The workflow runs on pull requests that touch `Darling/tools/*.ps1`, as the `Darling upgrade shapes` job in the nightly, and by manual dispatch. The release commit often carries no such check, so look for the run at its sha. In the release commit's checks or the nightly, confirm all 14 legs ran at that sha and are green, by name. A skipped leg is not a pass. If there is no run at that sha, start one with `gh workflow run darling-upgrade-shapes.yml --ref ` and wait for it. + +Also read the two pins at the top of the workflow, `DARLING_CURRENT_RELEASE` and `DARLING_OLD_RELEASE`. The first must name the last shipped release, and the second a release from before 3.9 that is still downloadable. Record the run URL. If any leg is red or skipped, stop. A red leg blocks the release, and re-running it until it passes is not a fix. + +#### (b) `upgrade-darling.ps1` over a real existing install + +Do the whole procedure twice: once from the last release, and once from the oldest release still supported. + +- **Which release is the oldest supported:** the oldest `Darling/Darling.Tests/Fixtures/migration-ladder-v.sql` in the tree. `MigrationUpgradeLadderLiveTests` climbs the current ladder over every fixture in that folder. Its `TheMostRecentRelease_HasALadderFixture` check keeps the newest shipped release in the set. So the oldest fixture is the oldest store the tests vouch for. Read the folder at release time, and do not copy a version number into this file. Deleting a fixture drops that release from support, so make it a deliberate decision and not a tidy-up. +- **Set up the old install:** download that release's Darling zip and extract it to `C:\Program Files\PerformanceMonitorDarling`. Write a `darling.json` that points at one throwaway test instance. Install it the way that release documented: its `install-darling.ps1`, or the manual steps in the README's "Upgrading from a build that predates the script" section when that release has no script. Let it collect for at least two cycles. Before upgrading, record `MAX(version)` from `darling_schema_version` and the account the service runs as. Also record the row counts of two or three `collect.*` tables. +- **Upgrade:** extract the new release zip to a staging folder under `C:\Program Files\` that only administrators can write to. From an elevated PowerShell, run that copy's `upgrade-darling.ps1 -Source `. On one of the two runs, point `-Source` at the downloaded zip with `-Sha256` from the release page, so the hash path runs too. When the old release predates the script, the new zip's script still runs over it, because it finds the install through the registered service. If the README still tells those users to take the manual procedure, walk that once as well. Record which path worked. +- **Pass, at the script:** it exits 0 without a refusal. It prints that the SHA256 was verified (zip run), that `darling.json` is byte-identical, that the install manifest was written, and "Service is Running". +- **Pass, 10 to 15 minutes later:** work the five checks the script prints against the store. + 1. `MAX(version)` equals the new build's top rung. + 2. `collect.collection_log` has rows for every configured server in the last 15 minutes. + 3. The collector count is in the mid-30s, not single digits. + 4. Every non-SUCCESS row since the restart gets read. YIELDED is the lock-timeout guard working. Anything else is a finding. + 5. One table the release added or changed shows new rows. + + The row counts you recorded before the upgrade must still be there, and the service account must be unchanged. A service that is Running but not collecting is a fail. +- **What the tests already cover:** the `*RungTests` classes in `Darling/Darling.Tests` pin each migration rung's SQL and probes on every build, with no database. `MigrationUpgradeLadderLiveTests` replays the current ladder over each released store on a scratch PostgreSQL, in the `Darling PostgreSQL tests` job. `DarlingStoreUpgradeTests` and `DarlingStoreUpgradeRevertTests` cover the bundled runtime swap and the in-place PostgreSQL upgrade. They use the old and new runtimes that `Darling/tools/new-upgraded-store-fixture.ps1` builds, and the nightly sets that up. +- **What the live run adds:** none of those tests runs the upgrade script or the Windows service manager. None of them sees the file ownership and permissions of an install an older build made, or a store holding real rows. +- **Record:** the from and to versions, the install path, and the schema version before and after. Add the five check results and the tail of the script's output. + +#### (c) A fresh `install-darling.ps1` run + +Use a machine with no prior install and no `C:\ProgramData\PerformanceMonitorDarling` folder.

The compose file names `:latest`, which still points at the previous release until this one publishes. So run the check with this release's own image tag (`:`), set in the compose file or by an override file for the check. Pass: `docker compose ps` shows the darling container healthy (not `unhealthy`). The log shows the config load and `Postgres store ready`. `collection_log` fills, as in the Windows checks. +- **Fresh install, systemd:** extract the tarball to `/opt/darling` and install `libgssapi-krb5-2`. Write the unit from the README. Point `DARLING_CONFIG` at a config for a throwaway PostgreSQL 15+ with TimescaleDB, and start it. Pass: the unit is active and the same store checks hold. +- **Upgrade:** repeat each shape over a store the previous release created. For compose, keep the volume and recreate the container from this release's compose file and image. For systemd, stop the unit, move `/opt/darling` aside, extract the new tarball, keep the config, and start the unit. Pass: the service starts, the store migrates to the new top rung, and collection continues with the earlier rows still present. +- **Oldest supported:** apply the same fixture rule as (b). If that release did not ship a Linux tarball, say so in the record and use the oldest release that did. +- **Record:** the same fields as (b), plus the image digest or tarball checksum you tested. + +Put the outcome of (a) to (d) in the release's test record.
