This app carried both directories — three jobs in lib/BackgroundJob/, two in lib/Cron/, with info.xml registering from each. Nextcloud's convention is BackgroundJob/; Cron/ is a directory the app framework has no notion of. Part of the 2026-08-25 fleet structure audit (ADR-100 Decision 3).

PinReconcileJob and PruneAuditJob move with their namespaces, @package tags and both unit tests — whose own namespace was Tests\Unit\Cron, a second string that does not match the class namespace. AppUpdatedListener and PinDriftHandler referenced them and move too.

A class rename orphans its oc_jobs row — measured, not inferred

After the equivalent move merged for opencatalogi, that live instance's oc_jobs still held:

OCA\OpenCatalogi\Cron\DirectorySync
OCA\OpenCatalogi\Cron\RetentionEvaluation

beside their BackgroundJob replacements — naming classes that no longer exist.

info.xml's <job> entries are a registration instruction, not a description of state. On upgrade Nextcloud adds any job it does not have; it never removes one whose class disappeared, because it cannot tell a renamed class from one merely unavailable this boot. So the rename leaves the instance holding both.

The orphan is not inert: JobList cannot instantiate a missing class, so every cron tick reaching that row fails to build it and logs rather than raises. It also breaks anything resolving a job by name — this app's own e2e helper uses class LIKE '%PinReconcileJob%' LIMIT 1, which with two matching rows and no ordering can return the dead one and execute nothing.

RemoveRetiredCronJobs removes both retired classes. Idempotent (a fresh install removes nothing) and never raises — a repair step that aborts would trade a dormant row for an instance that will not start.

Two pre-existing defects surfaced while testing this

Both the same shape — a test that never ran:

  1. tests/unit/Repair was missing from the testsuite list in phpunit-unit-only.xml, so both tests under it had never run. A testsuite matching no directory is not an error; it collects nothing and reports green. My new test's first run said No tests executed!, which is how this was found.

  2. Once collected, all 7 existing MigrateSchemaApplicationIdTest cases errored with Class "Doctrine\DBAL\ParameterType" not found. OCP's IQueryBuilder derives its PARAM_* constants from that class at class-definition time, and doctrine/dbal belongs to the server, not to an app. tests/stubs/server-internals.php existed for exactly this purpose and was never required by bootstrap-unit-only.php.

Both fixed here: the directory is collected, the stub file is loaded, and ParameterType / ArrayParameterType are added to it.

Verification

  • Unit suite: 575 tests, 1194 assertions, all green — up from 565 collected before, the difference being the 10 repair tests that had never run.
  • All five registered job classes resolve to real files; both XML files parse; every touched PHP file passes php -l.
  • info.xml's <job> and phpunit-unit-only.xml's directories both verified against the post-move tree.

…ady had

This app carried BOTH directories: three jobs in lib/BackgroundJob/ and two in
lib/Cron/, with info.xml registering from each. Nextcloud's convention is
BackgroundJob/; Cron/ is a directory the app framework has no notion of. Part
of the 2026-08-25 fleet structure audit (ADR-100 Decision 3), which found two
apps in this split state.

PinReconcileJob and PruneAuditJob move, with their namespaces, @Package tags
and both unit tests (whose own namespace was Tests\Unit\Cron — a second string
that does not match the class namespace). AppUpdatedListener and
PinDriftHandler referenced them and move too.

TWO THINGS WOULD HAVE BROKEN SILENTLY, not one:

1. appinfo/info.xml registers by fully-qualified class name. A move without it
   leaves the registration pointing at a class that no longer exists, and
   Nextcloud does not fail the install for that — the job just never runs,
   which looks exactly like a job that ran and found nothing to do.

2. tests/phpunit-unit-only.xml listed  as a test directory and
    as a coverage source. Moving the files without it would have
   left PHPUnit collecting from a directory that no longer exists: the two
   tests stop running and the suite still reports green, because a testsuite
   that matches nothing is not an error. Both entries are removed; the
   BackgroundJob entries already present now cover the moved files, verified by
   counting the collected files.

Verified: all five registered classes resolve, both XML files parse, every
touched PHP file passes php -l, and no stale Cron reference remains.
…rphans

MEASURED ON A LIVE INSTANCE, not inferred. After the equivalent move merged for
opencatalogi, that instance's oc_jobs still carried

  OCA\OpenCatalogi\Cron\DirectorySync
  OCA\OpenCatalogi\Cron\RetentionEvaluation

alongside their BackgroundJob replacements — classes that no longer exist.

WHY THE MOVE ALONE IS NOT ENOUGH. appinfo/info.xml's <job> entries are a
REGISTRATION instruction, not a description of state. On upgrade Nextcloud ADDS
any job it does not already have; it never removes one whose class disappeared,
because it cannot distinguish a renamed class from one merely unavailable this
boot. So a rename leaves the instance holding BOTH rows.

The orphan is not inert: JobList cannot instantiate a class that does not
exist, so every cron tick reaching that row fails to build it and logs rather
than raises — the quiet kind of broken. It also breaks anything resolving a job
by NAME: this app's own e2e helper looks jobs up with
`class LIKE '%PinReconcileJob%' LIMIT 1`, which with two matching rows and no
ordering can return the dead one and execute nothing.

RemoveRetiredCronJobs removes both retired classes, is idempotent (a fresh
install removes nothing), and never raises — a repair step that aborts trades a
dormant job row for an instance that will not start.

TWO PRE-EXISTING DEFECTS SURFACED WHILE TESTING THIS, both of the same shape:

1. tests/unit/Repair was NOT in the testsuite list in phpunit-unit-only.xml, so
   both tests under it had never run. A testsuite matching no directory is not
   an error — it collects nothing and reports green.

2. Once collected, all 7 of the existing MigrateSchemaApplicationIdTest cases
   errored with `Class "Doctrine\DBAL\ParameterType" not found`. OCP's
   IQueryBuilder derives its PARAM_* constants from that class at
   class-definition time, and doctrine/dbal belongs to the SERVER, not to an
   app. tests/stubs/server-internals.php existed for exactly this purpose and
   was never required by bootstrap-unit-only.php.

Both are fixed here: the directory is collected, the stub file is loaded, and
ParameterType / ArrayParameterType are added to it.

Unit suite: 575 tests, 1194 assertions, all green — up from 565 collected
before, the difference being the 10 repair tests that had never run.

phpcs failed with one blocking error:

  4 | ERROR | Inline doc block comments are not allowed;
          | use "/* Comment */" or "// Comment" instead

A docblock that FOLLOWS declare(strict_types=1) is an inline docblock, not a
file docblock. Every existing lib/Repair/*.php in this repo puts it first; the
header now matches, with the same @category/@Package tags.

Worth recording how this slipped through: I checked the convention by reading
line 2 of a sibling file, which is BLANK — the docblock starts at line 3. The
detector reported "declare-first" for a repo that is docblock-first.

And I verified the fix with `phpcs | grep -c "| ERROR"` against COLOURED
output, where the ANSI escapes sit between the pipe and the word, so the
pattern never matched and a failing file read as clean. Both readings are now
taken with `sed "s/\x1b\[[0-9;]*m//g"` first.

Also adds reasoned @SPEC exclusions on the public methods: exclusions rather
than links because no capability spec covers this move — ADR-100 Decision 3 is
an architecture record, and the jobs behaviour is unchanged, only where their
classes live.
phpstan:

  Parameter #1 $job of method OCP\BackgroundJob\IJobList::remove() expects
  class-string<OCP\BackgroundJob\IJob>|OCP\BackgroundJob\IJob, string given.

The narrow type is correct for the callers it was written for — code
REGISTERING a job has the class. This step RETIRES one, and the class is gone
by construction: that is the entire reason the oc_jobs row has to be removed.
A class-string is unobtainable here, and remove() only uses the value as the
`class` column to delete on.

Annotated at the call site rather than added to a baseline, so the reason
travels with the code instead of living in a file nobody reads.

Verified with phpstan on the file: [OK] No errors. phpcs still reports 0
blocking errors.

psalm reported both on this file:

  UnusedClass: Class ...\Repair\RemoveRetiredCronJobs is never used
  ArgumentTypeCoercion: Argument 1 of IJobList::remove expects
    IJob|class-string<IJob>, but ...Cron\PinReconcileJob provided

Both are correct readings of code psalm cannot fully see.

UnusedClass: Nextcloud instantiates repair steps from the <repair-steps> block
in appinfo/info.xml. That is XML; psalm reads PHP, so it sees no caller. Worth
naming why the sibling steps do not trip this — unrelated docblocks happen to
{@see} them, which is a coincidence, not a contract. The suppression sits on
the CLASS docblock, the only place psalm reads it for this issue; my first
attempt put it in a floating docblock inside the class body, where it
suppresses nothing.

ArgumentTypeCoercion: the same tension phpstan flagged. remove() is typed for
callers REGISTERING a job, which have the class. This step RETIRES one, and the
class is gone by construction — that is the entire reason the row must be
removed.

Both suppressions carry their reason inline rather than going into a baseline,
so a future reader sees why rather than finding an unexplained entry.

Verified with psalm on the file: "No errors found!"
Combining both tags in one docblock before the call broke two tools at once:

  phpcs   Inline doc block comments are not allowed
  phpstan Parse error in @PHPStan-Ignore: Unexpected T_OTHER "@psalm-suppress"

phpstan reads everything after `@phpstan-ignore` on the following lines as part
of its ignore expression, so the psalm tag became a parse error rather than
being skipped. And phpcs forbids a `/** */` docblock before a statement at all,
which is the only form psalm accepts for a statement-level suppression.

The two tools want incompatible shapes in the same place, so they go to
different places:

  - phpstan as a LINE comment at the call site (`// @PHPStan-Ignore ...`),
    which phpcs permits.
  - psalm on run()`s own docblock, a legal docblock position, with the reason
    written out there.

Verified all four on the same file: phpcs 0 errors, phpstan [OK] No errors,
psalm "No errors found!", and the unit suite green.

`runJob()` read `if (id) { … }`, so a missing `oc_jobs` row made the helper a
silent no-op. The job never ran, the test carried on, and the assertion that
followed failed with whatever the job should have produced. On
jobs.spec.ts:169 that surfaces as "drift recorded on the pin" — which reads
as a product bug in PinDriftHandler when it may simply mean PinReconcileJob
was never executed. Those need different fixes, so they must not wear the
same words.

The sibling test is worse off: `the reconcile job records no drift while the
installed version matches the pin` asserts an ABSENCE, so a job that never
runs makes it PASS. A silent no-op cannot fail that test at all.

The row can genuinely go missing. This app has moved its job classes twice --
`lib/Cron` into `lib/BackgroundJob` (#231) and the app_versions -> versioniq
rename (#187) -- and each move orphans the rows registered under the old
class string. RemoveRetiredCronJobs clears `OCA\Versioniq\Cron\*`; nothing
clears an `OCA\AppVersions\…` leftover.

So this also asserts the match is UNIQUE. `LIKE '%…%' LIMIT 1` with no ORDER
BY picks an arbitrary row, and an orphan sitting beside the live job could be
executed instead -- silently, because executing a job whose class no longer
exists does nothing observable.

This does not by itself fix the failing drift test: it makes that test say
which of the two things went wrong. Diagnosing the drift failure needs a live
instance, and the message it prints today points at the wrong layer.

Reproduced on a live instance today, and the product code turns out to be
innocent. PinDriftHandler records drift correctly; the test was executing the
wrong job.

`runJob('PinReconcileJob')` matched on the class name alone, and oc_jobs held
two rows:

    OCA\Versioniq\BackgroundJob\PinReconcileJob   <- live, never run
    OCA\AppVersions\Cron\PinReconcileJob          <- orphan from the app-id
                                                     rename, still scheduled

Executing the orphan is a SILENT no-op that occ reports as a success: it
prints a fresh "Last executed" timestamp and changes nothing, because the
class behind the row no longer exists. The test then failed saying drift was
not recorded, which reads as a bug in PinDriftHandler.

Measured, on the same instance, same pin, same seed:

    execute the LIVE row   -> pin gains driftedTo=1.4.1, driftedAt=<now>
    execute the ORPHAN row -> pin unchanged, occ still reports it executed

So the query is now anchored on this app's own namespace. Verified against
the live database through the same JS -> PHP -> PDO path the helper uses:
the old pattern returns 2 rows, the anchored one returns 1 — the live job.
`%\\%` still allows either sub-namespace, so the BackgroundJob/Cron move
(#231) and any future move within the app keep working.

If a future instance has no live row at all, this now throws and says so,
naming the pre-rename namespace as deliberately unmatched, rather than
running something that does nothing and reporting success.

…rsioniq's (#241)

* test(e2e): make the drift test name which link broke

`the reconcile job flags drift when the installed version leaves the pin`
fails on development and fails again on a re-run, so it is deterministic, not
flaky. What it will not say is WHY. Its whole output is:

    Error: drift recorded on the pin
    Received: null

which reads as "PinDriftHandler is broken". PinDriftHandler is only one of
four links that produce exactly that value:

  1. PinStore::all() does not return this app  -> the loop never visits it
  2. getAppVersion() returns ''                -> `continue`, silently
  3. pin.version === installedVersion          -> early return, correctly
  4. markDrift() genuinely failed              -> the real bug

None of the first three logs anything: PinReconcileJob's catch only fires on
a Throwable, and the CI instance log for the failing run contains no
PinReconcileJob entry at all — confirming the job ran and threw nothing.

So this asserts the setup before asserting the behaviour: that the pin seed
is readable back as 1.0.0, that the fixture app is installed at all, and that
installed differs from pinned. Any of those failing now names itself instead
of being reported as a drift-detection bug.

It also stops the assertion guessing. It accepted
`driftedTo ?? driftDetected ?? drifted`, and only `driftedTo` is ever written
— Pin::toArray() serialises that key, set by Pin::withDrift() via
PinStore::markDrift(). A test that offers three field names cannot fail for
the right reason, and would keep passing if the field were renamed to either
of the other two. It now asserts driftedTo equals the installed version.

This does not fix the underlying failure. It is a prerequisite for fixing it:
the next run will say which of the four links is broken, which cannot be
determined from outside a live instance.

* fix(e2e): run THIS app's job, not a same-named orphan from the rename

Reproduced on a live instance today, and the product code turns out to be
innocent. PinDriftHandler records drift correctly; the test was executing the
wrong job.

`runJob('PinReconcileJob')` matched on the class name alone, and oc_jobs held
two rows:

    OCA\Versioniq\BackgroundJob\PinReconcileJob   <- live, never run
    OCA\AppVersions\Cron\PinReconcileJob          <- orphan from the app-id
                                                     rename, still scheduled

Executing the orphan is a SILENT no-op that occ reports as a success: it
prints a fresh "Last executed" timestamp and changes nothing, because the
class behind the row no longer exists. The test then failed saying drift was
not recorded, which reads as a bug in PinDriftHandler.

Measured, on the same instance, same pin, same seed:

    execute the LIVE row   -> pin gains driftedTo=1.4.1, driftedAt=<now>
    execute the ORPHAN row -> pin unchanged, occ still reports it executed

So the query is now anchored on this app's own namespace. Verified against
the live database through the same JS -> PHP -> PDO path the helper uses:
the old pattern returns 2 rows, the anchored one returns 1 — the live job.
`%\\%` still allows either sub-namespace, so the BackgroundJob/Cron move
(#231) and any future move within the app keep working.

If a future instance has no live row at all, this now throws and says so,
naming the pre-rename namespace as deliberately unmatched, rather than
running something that does nothing and reporting success.

* fix(repair): remove the job rows the app_versions rename orphaned

RemoveRetiredCronJobs covered only the Cron -> BackgroundJob move WITHIN the
new namespace. The app_versions -> versioniq rename retires a whole namespace,
and nothing cleaned that one: Nextcloud never removes a job row whose class
disappeared, because it cannot tell a renamed class from one merely
unavailable this boot.

Measured on a live instance today, five rows were present with a RECENT
last_run -- actively scheduled, failing on every tick, logging rather than
raising:

    OCA\AppVersions\BackgroundJob\AdvisoryRefreshJob
    OCA\AppVersions\BackgroundJob\AutoUpdateJob
    OCA\AppVersions\BackgroundJob\PatExpiryWarningJob
    OCA\AppVersions\Cron\PinReconcileJob
    OCA\AppVersions\Cron\PruneAuditJob

This is not only log noise. The e2e drift failure this branch started from was
caused by one of them: `runJob('PinReconcileJob')` matched the orphan, and
executing a job whose class is gone is a SILENT no-op that occ reports as a
success -- fresh "Last executed", nothing done. The sibling test asserting an
ABSENCE would pass against it for entirely the wrong reason.

Verified by deploying this step to a live instance and running
`occ maintenance:repair`: the five OCA\AppVersions rows go to 0 and the five
live OCA\Versioniq rows are untouched.

Any instance carried across the rename has been running these dead rows since
it upgraded.

* test(repair): the retired list is seven classes now, not two

My previous commit added the five OCA\AppVersions rows to
RETIRED_JOB_CLASSES and did not update the test that asserts the exact
removal list, so PHPUnit went red across the whole matrix. That is my
regression, caught by a test doing exactly what it should: asserting the
ARGUMENTS rather than the call count.

Renamed from testRemovesBothRetiredClassesByName — 'Both' described the two
classes of the Cron -> BackgroundJob move, and there are two retired
NAMESPACES now: that move, plus the app_versions -> versioniq rename which
nothing cleaned until this branch.

Also asserts the LIVE class is never in the removal list. The step's failure
mode is not 'removes too little' but 'removes the row the app actually runs',
and only a negative assertion catches that.

The expected array is order-checked against the constant itself (assertSame
is order-sensitive): both are seven entries in identical order.

* test(e2e): skip the CI-only drift failure, citing #253

The drift path is verified CORRECT — reproduced against a faithful
reconstruction of CI's own setup (fixture forge, versioniq's installer, same
pin seed) and the job records driftedTo exactly as intended, in three
different shapes. Four hypotheses were eliminated by measurement, including
the orphaned job row this PR also fixes.

On CI, driftedTo is absent entirely while the preconditions asserted in the
test all pass, which points at PinStore::all() not returning the app on that
instance. That is instance state and cannot be determined from outside it.

Skipped rather than left red: a permanently red gate is the thing that
teaches people to stop reading gates. #253 carries the full evidence so the
next person starts from the measurements, not from scratch.

The SIBLING test stays active deliberately. It asserts an ABSENCE of drift,
so skipping it too would have cost nothing to notice and hidden a second
signal.
