Still adding tests but wanted to get this up for review of the overall "shape" of the fix When certain things happen like installer updates we delete pending upcoming_activities(UA) and host_software_install(HSI) entries and need to mark setup_experience_status_results(SESR) cancelled. When this happens if that UA/HSI are being depended on by setup experience we need to make sure that that setup experience result eventually gets marked failed. I kind of went back and forth a few times on how best to do this and avoid race conditions. One thing I tried was looking at existence of the UA/HSI but found that naively just trying to look at that in relation to the SESR entry seemed to have a few race conditions that were hard to resolve. There are a few possible states here we need to account for such as: un-activated, totally not yet running software install cancelled activated but not yet running on the host software install cancelled activated and running on the host software install cancelled before results are completely reported back What I eventually came around to was essentially that we want to mark the SESR cancelled in the same transaction we delete the HSI/UA in. We then finalize it by marking it failed and sending the activity the next time the host fetches setupm experience results. The new cancelled status never leaves fleet. This is a bit ugly but in my testing avoided the race conditions and works well. Note that to actually avoid setup experience hanging entirely we still need to fix #29357 which encompasses several cases where the unified queue can get completely stuck for a host # Checklist for submitter If some of the following don't apply, delete the relevant line. <!-- Note that API documentation changes are now addressed by the product design team. --> - [ ] Changes file added for user-visible changes in `changes/`, `orbit/changes/` or `ee/fleetd-chrome/changes`. See [Changes files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/guides/committing-changes.md#changes-files) for more information. - [ ] Input data is properly validated, `SELECT *` is avoided, SQL injection is prevented (using placeholders for values in statements) - [ ] Added support on fleet's osquery simulator `cmd/osquery-perf` for new osquery data ingestion features. - [ ] If paths of existing endpoints are modified without backwards compatibility, checked the frontend/CLI for any necessary changes - [ ] If database migrations are included, checked table schema to confirm autoupdate - For database migrations: - [ ] Checked schema for all modified table for columns that will auto-update timestamps during migration. - [ ] Confirmed that updating the timestamps is acceptable, and will not cause unwanted side effects. - [ ] Ensured the correct collation is explicitly set for character columns (`COLLATE utf8mb4_unicode_ci`). - [ ] Added/updated automated tests - [ ] Manual QA for all new/changed functionality - For Orbit and Fleet Desktop changes: - [ ] Make sure fleetd is compatible with the latest released version of Fleet (see [Must rule](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/workflows/fleetd-development-and-release-strategy.md)). - [ ] Orbit runs on macOS, Linux and Windows. Check if the orbit feature/bugfix should only apply to one platform (`runtime.GOOS`). - [ ] Manual QA must be performed in the three main OSs, macOS, Windows and Linux. - [ ] Auto-update manual QA, from released version of component to new version (see [tools/tuf/test](../tools/tuf/test/README.md)). - [ ] For unreleased bug fixes in a release candidate, confirmed that the fix is not expected to adversely impact load test results or alerted the release DRI if additional load testing is needed. |
