Handle workflows whose board or stack was deleted
Deleting a board or stack left the workflow row pointing at nothing: Deck
keeps the orphaned cards readable until its DeleteCron purges them, so the
run kept failing on the move every few minutes, silently and forever.

- The controller now rejects boards and stacks that do not exist (or are not
  the user's) on create and update, so no new broken row can be stored.
- The settings list marks affected workflows in red instead of showing a row
  that looks healthy.
- The background job disables such a workflow and mails its owner once. The
  mail ignores the notifyEmail flag: that one is about moved cards, this is a
  notice that the automation stopped. It stays a one-off because a disabled
  workflow is no longer picked up.

The check deliberately goes through StackService::findAll() rather than
BoardService::getUserBoards(): Deck injects the current user into BoardService
as a string frozen at construction, so in the job -- one process, many users,
a cached BoardService -- it would answer for the wrong user or for none, and
every workflow on the instance would have been disabled. findStackIds()
returns null only for a genuinely missing or forbidden board and throws for
anything else, so a Deck outage skips the workflow instead of killing it.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

A Nextcloud app (workflow_deck_automation, namespace WorkflowDeckAutomation) targeting Nextcloud Hub 26 Spring (server 34.x). It lets each user configure, from their personal settings, automation "workflows" that move overdue Deck cards from one stack to another, with optional assigned-user/label filters and an email notification. A background TimedJob evaluates all enabled workflows every 5 minutes.

Non-negotiable architectural constraint

No HTTP/OCS calls against Deck, anywhere. Every read (boards, stacks, cards, labels, assigned users) and the card move itself must go through Deck's own internal PHP classes (OCA\Deck\Service\CardService, StackService, BoardService, OCA\Deck\Db\CardMapper, …), resolved in-process via \OCP\Server::get(). This was an explicit, repeated product requirement from the user — do not "fix" it by switching to IClientService/curl against /ocs/..., even though that would be the more conventional cross-app integration approach.

All Deck access is funneled through lib/Service/DeckIntegrationService.php — it is the only class that references OCA\Deck\*. If you need new Deck data, extend that class rather than reaching into Deck internals from elsewhere. Every call in there is wrapped (class_exists() checks, IAppManager::isEnabledForUser('deck', …), try/catch → DeckUnavailableException) because OCA\Deck\* is not a documented/stable public API — it has no @since markers and can change between Deck releases without notice.

Per-user impersonation in the background job

Deck's ACL/permission checks read the live IUserSession, not a value frozen at construction. RunWorkflowsJob (a TimedJob) has no logged-in user by default and must evaluate workflows belonging to many different users within one PHP process. lib/Service/WorkflowRunner.php therefore groups workflows by owner and, per owner, temporarily impersonates them (IUserSession::setUser(), restored in a finally) before touching Deck. Don't remove this — without it, Deck's permission checks inside the cron run would be evaluated against no user (or the wrong user).

The filter-matching logic (WorkflowRunner::cardMatchesFilters(), ::isOverdue()) is deliberately static and side-effect-free so it's unit-testable without a real Deck installation — see tests/Unit/Service/WorkflowRunnerFilterTest.php.

Not everything in Deck reads the live session, though. BoardService takes the current user as private ?string $userId — a plain string frozen when the container builds it. getUserBoards() uses exactly that, so in the background job (one process, many users, a container-cached BoardService) it answers for whoever happened to be impersonated at first resolution, or for null. listBoardsForCurrentUser() is therefore request-only; the job asks findStackIds() instead, which goes through StackService::findAll()PermissionService → live session. Before using any other OCA\Deck\* service from the runner, check which of the two kinds it is — the failure mode is silent and user-crossing, not an error.

Workflows are auto-disabled when their Deck targets vanish

WorkflowRunner::findBrokenTarget() checks board and stacks before every run and, if something is gone, switches the workflow off (enabled = false) and sends a one-off mail. Two invariants hold this together and must survive refactors:

  • Only positive knowledge disables. DeckIntegrationService::findStackIds() returns null only for "board missing/not readable" (DoesNotExistException, Deck's NoPermissionException/NotFoundException) and throws for everything else. The runner skips the workflow on a throw. If you make that method degrade to []/null on generic errors, a Deck outage will disable every workflow on the instance and mail every user about it.
  • The mail ignores the notifyEmail flag — that flag is about moved cards; this is a notice that the user's configuration stopped working. It stays a one-off simply because a disabled workflow is not picked up by findAllEnabled() again.

Archived boards deliberately do not trigger this (they stay readable, so findStackIds() succeeds), even though they're filtered out of the settings dropdowns.

Job interval comes from config.php

RunWorkflowsJob reads workflow_deck_automation.interval (seconds, default 300, clamped to a 60s minimum) via IConfig::getSystemValueInt() in its constructor. That works because TimedJob re-reads $this->interval on every cron pass from the freshly constructed job — so editing config.php takes effect immediately, with no occ command and no re-registration. Don't move this into appinfo/info.xml or a stored app config; the constants (INTERVAL_CONFIG_KEY, DEFAULT_INTERVAL, MINIMUM_INTERVAL) on the job are the single source of truth and are referenced from the README.

The job must stay IJob::TIME_SENSITIVE. It was TIME_INSENSITIVE at first, which looked harmless and was not: OC\Core\Service\CronService::runCli() reads maintenance_window_start (default 100, i.e. unset) and, whenever the current UTC hour is outside [start, start+4], calls jobList->getNext($onlyTimeSensitive = true) — time-insensitive jobs are then skipped for the other 20 hours of the day. On an instance with a maintenance window configured (Nextcloud's admin overview nags admins into setting one) the job simply never ran, showing last_run = 1970-01-01 in occ background-job:list indefinitely. Note this gate only exists in runCli(), so it doesn't apply to ajax/webcron mode, and passing job classes explicitly (occ background-job:worker '<class>') bypasses it — which is exactly why manual testing can look fine while cron does nothing.

Changing the sensitivity in code does not fix an already-registered job. getNext() filters on the time_sensitive column of oc_jobs, and JobList::setLastRun() is a one-way ratchet:

if ($job instanceof TimedJob && !$job->isTimeSensitive()) {
    $query->set('time_sensitive', $query->createNamedParameter(IJob::TIME_INSENSITIVE));
}

There is no else. Once a job has run while declaring itself insensitive, the row is stamped TIME_INSENSITIVE for good — and nothing resets it: JobList::add() only writes the column in its insert branch, and re-registering an existing job (app update, app:enable) takes the update branch, which leaves it alone. So after deploying the TIME_SENSITIVE change, an existing instance still needs its row fixed once:

UPDATE oc_jobs SET time_sensitive = 0
 WHERE class = 'OCA\\WorkflowDeckAutomation\\BackgroundJob\\RunWorkflowsJob';

or, without DB access, occ background-job:delete <id> followed by occ app:disable workflow_deck_automation && occ app:enable workflow_deck_automation to get a freshly inserted row. Fresh installs are unaffected.

To debug this job on a server: occ background-job:list --class '<class>' for its id and last run, then occ background-job:execute <id> --force-execute to run it right now regardless of the interval. occ background-job:worker takes job classes, not an app id.

Registration is declarative, not Bootstrap-based

Background jobs and classic personal settings are registered in appinfo/info.xml (<background-jobs>, <settings><personal>/<personal-section>), not via IRegistrationContext in lib/AppInfo/Application.php — that interface has no registerBackgroundJob()/registerSettings() methods on NC 34. Application.php is intentionally near-empty.

Commands

PHP and npm are not available in the local dev sandbox this repo is normally edited from. Do not try to run composer, php, or npm locally to verify changes — they will fail with "command not found". Verification happens by pushing to main (or opening a PR) and checking the Gitea Actions run; the self-hosted runner tag is gitea-runner-server03 (see .gitea/workflows/*.yml, all pinned to that runs-on: label).

Commands as they'd run in CI/on a machine that has the tools:

composer install
composer run lint       # php -l over lib/ and tests/
composer run cs:check   # nextcloud/coding-standard (php-cs-fixer); composer run cs:fix to auto-fix
composer run test:unit  # PHPUnit — pure logic only, no live Deck/Nextcloud instance needed

npm install              # no package-lock.json is committed (gitignored) — use install, not `npm ci`
npm run build             # production build
npm run watch              # rebuild on change during development

To run a single PHPUnit test: vendor/bin/phpunit --filter testUserFilterIsOrAgainstAssignedUsers tests/Unit/Service/WorkflowRunnerFilterTest.php.

There is no meaningful way to test the Deck integration itself outside a real Nextcloud+Deck instance (php occ background-job:worker 'OCA\WorkflowDeckAutomation\BackgroundJob\RunWorkflowsJob' — the argument is a job class, not an app id) — the unit tests intentionally stop at the pure filter logic.

Release process

  1. Bump <version> in appinfo/info.xml and version in package.json (keep them in sync).
  2. Commit, push to main, confirm the run of .gitea/workflows/build-main.yml is green.
  3. git tag vX.Y.Z && git push origin vX.Y.Z — this triggers the tag branch of the same workflow, which re-runs the checks, builds the frontend, runs make appstore, and attaches workflow_deck_automation.tar.gz as the asset on a normal (non-pre-) release for that tag.

If the tagged build fails and no artifact was ever produced, fix the issue on main and move the existing tag to the fixed commit instead of bumping to a new version number (git tag -d vX.Y.Z && git tag -a vX.Y.Z -m "..." && git push origin :refs/tags/vX.Y.Z && git push origin vX.Y.Z) — this is how v0.1.0 was handled through several build fixes before it first built successfully. The job deletes any pre-existing release for the tag before creating the new one, so a moved tag republishes cleanly instead of failing on a duplicate asset name. Once a version has actually produced a published artifact, don't move its tag anymore; bump normally instead.

No actions/upload-artifact anywhere — and don't reintroduce it. This self-hosted Gitea instance identifies as GHES to the official actions/* JS actions, which refuse to run @actions/artifact v2.0.0+ (used internally by upload-artifact@v4 and later) against GHES: GHESNotSupportedError, which pinned us to @v3 for a while. Publishing through the Gitea release REST API with curl sidesteps that version-specific backend API entirely, so the build workflow uses that instead. actions/checkout and actions/setup-node were never affected — only the artifact upload/download actions are, because they're the ones talking to a versioned backend rather than just running local commands — and can stay on their latest majors.

One workflow for everything

.gitea/workflows/build-main.yml is the only workflow: it carries the checks (php-lint across 8.2/8.3/8.4, xml-lint, unit-tests) and the package job that builds and publishes. They used to be four separate workflow files, which meant they all triggered independently on the same push and a latest-main release was published even when PHPUnit was red. needs: only works between jobs of the same workflow (and Gitea's workflow_run can depend on one workflow at a time), so gating the release on the checks required merging them into this file. Don't split them back out.

Consequences of that shape, all intentional:

  • package builds and publishes in one job. Handing the tarball to a separate publish job would need actions/upload-artifact (unusable here, see above) or actions/cache — a second Gitea backend API in the critical path for no gain.
  • The workflow also runs on pull_request, where the Publish release step is skipped via if: gitea.event_name == 'push' and the job degrades into a frontend-build check. That matters: npm run build used to run only on main, so no PR ever exercised it.
  • Tags now get linted and tested too. Previously the check workflows triggered only on main pushes and PRs, so a v* tag published completely unverified.

It runs on pushes to main and on v* tags, and the publish step branches on gitea.ref:

  • main → rolling pre-release tagged latest-main; both the release and the tag are deleted and recreated each run, so the download URL for workflow_deck_automation.tar.gz always serves the newest main build.
  • v* → normal release on the tag that was just pushed. Only a stale release is deleted here — never the tag, since deleting it would destroy the ref that triggered the run. That's what the RECREATE_TAG flag guards.

The latest-main half exists so a build can be grabbed and copied onto the server (nextcloud.gnilebein.de) without cutting a version tag first — it produced v0.1.0-shaped raw-repo confusion once already when the app directory was populated by copying the git working tree instead of a built package; this gives a one-click alternative to that mistake.

Note that make appstore is pure mkdir/tar/rm — no composer, no php. The package job therefore needs Node only; a setup-php step there would be dead weight (the deleted release workflow had one). PHP is set up in the check jobs, which is a different job and a different container.

No manually created token is needed. The publish step authenticates with secrets.GITEA_TOKEN, the token Gitea injects into every Actions job automatically (Gitea 1.27.1 here). The job declares permissions: contents: write, which Gitea maps to Code: write (needed to delete the latest-main tag) plus Releases: write (creating the release and uploading the asset).

This replaced an earlier hand-made RELEASE_TOKEN repo secret. If the publish step ever starts returning 403s, check the repo/org default token permission mode: permissions: requests are clamped by MaxTokenPermissions, so a repository switched from Permissive (the backwards-compatible default) to Restricted silently downgrades releases to read-only and no permissions: block can raise it back. That's a repo setting, not a workflow bug — don't "fix" it by reintroducing a PAT before checking.

Data flow / architecture map

  • UI: src/PersonalSettings.vue (Vue 3, mounted from templates/settings/personal.php into the section registered by lib/Settings/PersonalSection.php + lib/Settings/Personal.php) talks to lib/Controller/WorkflowController.php (an OCSController) via src/api.js, hitting OCS routes declared in appinfo/routes.php (/ocs/v2.php/apps/workflow_deck_automation/api/v1/...).
  • Storage: lib/Db/Workflow.php (Entity) / lib/Db/WorkflowMapper.php (QBMapper) over the wfda_workflows table, created in lib/Migration/Version1000Date20260813120000.php. Filter fields (filter_user_ids, filter_label_ids) are stored as JSON-encoded arrays in text columns, not join tables.
  • Automation: lib/BackgroundJob/RunWorkflowsJob.php (5 min TimedJob) → lib/Service/WorkflowRunner.php (per-user impersonation + filtering, both filters OR-within-themselves and AND-between-each-other) → lib/Service/DeckIntegrationService.php (all actual Deck class calls) and lib/Service/NotificationMailer.php (email via OCP\Mail\IMailer to the workflow owner's account address, never a manually-entered address).
  • Both the controller's board/stack/label/participant lookups (for populating the settings UI dropdowns) and the runner's card reads/moves go through the same DeckIntegrationService — there is no separate read path.

Composer/npm lockfiles are intentionally not committed

.gitignore excludes composer.lock and package-lock.json. This means CI must use composer install/npm install, not composer install --no-dev assumptions tied to a lock file or npm ci (which hard-requires a lock file and will fail otherwise — this has already broken the build workflow once). If you add a lockfile-dependent step, either commit the lockfile deliberately or keep using the non-ci/non-locked install form.

Frontend build gotchas already hit (don't reintroduce)

None of these were discoverable locally — there's no npm here (see "Local-only notes" below), so all three were only caught by an actual Gitea Actions run against the build workflow:

  • vite version must satisfy @nextcloud/vite-config's peer requirement. package.json pins @nextcloud/vite-config to ^2.2.0, which currently resolves to 2.5.4 and peer-requires vite@^7.3.6. If you bump @nextcloud/vite-config, check its peerDependencies.vite and bump our vite devDependency to match, or npm install fails with ERESOLVE.
  • package.json needs "type": "module". vite.config.js uses import/export syntax and @nextcloud/vite-config is ESM-only; without "type": "module", Node treats .js as CommonJS and vite build fails trying to require() an ESM-only package.
  • A tsconfig.json must exist at the repo root, even though this project has no TypeScript source. @nextcloud/vite-config's index.js barrel statically re-exports createLibConfig from libConfig.js, which imports vite-plugin-dts at module scope — that import chain runs just from importing createAppConfig, regardless of whether createLibConfig is ever called. The minimal tsconfig.json in this repo exists to give that a config to resolve, not because we write TypeScript. On its own this did not fix the crash below — see the next bullet.
  • typescript must be an explicit devDependency. vite-plugin-dts (pulled in transitively by the bullet above, version ^4.5.4 as of @nextcloud/vite-config@2.5.4) peer-depends on typescript: "*" but doesn't install it itself. Without a typescript devDependency in our own package.json, nothing provides that package, and vite-plugin-dts's @volar/typescript integration crashes at module-load time — before vite.config.js's own code or tsconfig.json are ever consulted — with Cannot read properties of undefined (reading 'useCaseSensitiveFileNames') (proxyCreateProgram). This is the actual fix; tsconfig.json existing is necessary but not sufficient. Keep typescript reasonably close to the version @nextcloud/vite-config itself develops against (currently ^5.9.3) if you bump either.
  • createAppConfig prefixes every entry name with the app id, so the entry personal-settings is emitted as js/workflow_deck_automation-personal-settings.mjs and css/workflow_deck_automation-personal-settings.css. Util::addScript()/addStyle() take that full on-disk basename (minus extension), not the bare entry name — lib/Settings/Personal.php therefore passes Application::APP_ID . '-personal-settings'. Getting this wrong produces a silently blank settings page: the template's empty mount <div> renders fine, and the only symptom is Could not find resource workflow_deck_automation/js/….js to load (jsresourceloader) plus a matching Could not find resource file "/apps/workflow_deck_automation/css/….css" in nextcloud.log. If you rename the entry in vite.config.js, rename it in Personal.php too.
  • The bulk of the CSS lives in a hashed *.chunk.css, loaded at runtime by the .mjs bundle (cssCodeSplit: true). The css/workflow_deck_automation-personal-settings.css that addStyle() points at is the ~100-byte stub produced by createEmptyCSSEntryPoints: true. A near-empty entry CSS file is expected — don't "fix" it by turning off code splitting.

@nextcloud/vue 9 component API (Vue 3) — the v8 idioms silently do nothing

This app is on @nextcloud/vue ^9 / Vue 3. The v8 (Vue 2) prop spellings that most Nextcloud app code online still uses either fail silently or, worse, land as stray DOM attributes instead of erroring:

  • No .sync. Vue 3 removed it. NcTextField and NcCheckboxRadioSwitch both bind through modelValue/update:modelValue, so it's v-model="x":value.sync="x" / :checked.sync="x" leave the bound state permanently at its initial value. That's how form.title stayed '' and every save died on "Bitte einen Titel angeben."
  • NcSelect's label prop is the option display key, not a caption (it's vue-select's). Passing label="Board" makes it read option.Board on every option and render undefined for all of them. The visible caption prop is input-label.
  • NcButton: variant is the style, type is the native button type, and native-type no longer exists (v8's type="primary" + native-type="submit" → v9's variant="primary" + type="submit"). A leftover type="primary" renders <button type="primary">, which HTML treats as the invalid-value default submit — so a cancel button silently submits the form.
  • NcSelect's reduce is not declared on NcSelect itself; it reaches vue-select through attribute fallthrough (NcSelect's root element is the VueSelect component and it doesn't set inheritAttrs: false). It works, but it's fallthrough, not a documented prop.
  • NcNoteCard's prop is still type (success|info|warning|error) — not everything was renamed to variant.

Deck entities are "relational": getters don't return the uid string

Deck's RelationalEntity swaps resolved relations for an OCA\Deck\Db\RelationalObject once an entity is enriched. So on an enriched board/card, $acl->getParticipant(), $board->getOwner() and a card assignment's participant return a RelationalObject (wrapping OCA\Deck\Db\User/Group/Circle), not a uid — the uid is its getPrimaryKey(). Probing for getUID() on the returned object finds nothing and yields null, which is how the settings UI's user dropdown came up empty and why the runner's assigned-user filter could never match. DeckIntegrationService::unwrapUid() handles both shapes (bare string and RelationalObject); route any new participant/owner field through it.

Two more Deck facts that bit us in the same pass: a board's ACL does not contain its owner (a private board has an empty ACL, so participants must be seeded with $board->getOwner()), and ACL entries can be groups (type === 1) whose members have to be expanded via IGroupManager.

BoardService::getUserBoards() defaults to $includeArchived = true, and that flag also gates the deleted_at = 0 condition — with the default you get archived and trashed boards back. We call getUserBoards(null, false) (with a fallback to the no-arg form if Deck ever changes the signature) and still dedupe by id afterwards, because it merges own/group/circle boards and can return the same board twice. Stacks need no such handling: StackMapper::findAll() filters deleted_at = 0 unconditionally and stacks have no archived state.

Local-only notes

CLAUDE.local.md (gitignored) carries session-specific environment notes (e.g. "no PHP/npm available locally"). Check it at the start of work in this repo — it's not duplicated here since it can change independently of the committed guidance.
