Creating a profile left the device on the old one. ProfileService.createProfile said so in its own doc comment — "Does not switch" — and duplicateProfile did the same, so the new profile appeared greyed out in the list and reaching it took a Switch click plus a second confirmation dialog. Both actions mean "use this profile now": you create a profile to set it up, and you duplicate one to experiment on the copy without touching the original.

Activation is routed through the drain-then-persist path an explicit switch already uses, extracted as a private activate() because exclusive() throws on re-entry and both callers are already inside it. The drain matters more here than the extra dialog it replaces: neither create path drained before, so a save still queued against the outgoing profile could be abandoned by the reload.

switchProfile keeps its existence check and the create paths do not get one — a freshly written slot needs no probe, since the write that created it was awaited, and asking the server "does this exist" immediately after writing it invites a confusing "no longer exists" from a lagging list.

Import is deliberately unchanged. Its doc comment records that decision, and importing to archive a config is a real use.

On the deferred-switch hole

#582 describes what happens when ReloadService declines the reload: the switch is deferred with nothing durable recording it. That does not meaningfully apply here. The profile write has to succeed before the reload probe runs, so the server would have to die between two adjacent requests — and an explicit Switch already carries the same exposure. This is not gated on #582.

The New and Duplicate buttons are both [disabled]="!canWriteUserData()", so a read-only session never reaches this path.

Verification

npm run ci clean: lint, strict-null gate, 2100 unit tests (up from 2098), 34 schema tests.

Five new tests, written before the change and confirmed failing against the old behaviour:

  • create activates the new profile
  • create drains the write queue before activating, asserted on invocationCallOrder rather than on both calls merely having happened
  • duplicate activates the copy, not the source
  • a storage failure during duplicate never activates
  • both dialogs tell the user Skip will reload, and the duplicate dialog names the source it leaves untouched

The existing "does not auto-switch into the created profile" test is replaced rather than deleted; the import test asserting the same property is untouched and now guards the deliberate difference.

Not exercised on a device: the reload itself. The activation path is the one an explicit switch already takes in production.

Closes #589

  • Creating or duplicating a profile activates the new profile and reloads the application.
  • The activation path drains pending writes before switching to preserve changes to the outgoing profile.
  • Duplication leaves the source profile unchanged and activates the copied profile.
  • Importing a profile does not activate it.
  • If storage draining fails, activation does not proceed.
  • Name dialogs explain that Skip reloads the application onto the new profile.
  • Tests cover activation, write-queue ordering, duplication, storage failures, and dialog messaging.

Creating or duplicating a profile left the device on the old one, so
reaching the new profile took a Switch click and a second confirmation.
Both actions mean "use this profile now".

Activation goes through the same drain-then-persist path an explicit
switch uses, so a save still queued against the outgoing profile is not
abandoned by the reload. Import keeps its own behaviour: it stays put,
because importing to archive a config is a real use.

Closes #589

📝 Walkthrough

Walkthrough

Profile creation and duplication now drain pending storage writes before activating the new profile. Configuration dialogs describe the automatic switch and reload. Tests cover activation failures and dialog text.

Changes

Profile Activation

Layer / File(s) Summary
Create and duplicate activation
src/app/core/services/profile.service.ts, src/app/core/services/profile.service.spec.ts
ProfileService drains pending writes before activation and rejects activation when draining fails. Creation and duplication activate the new profile. Tests cover activation and storage failures.
Dialog descriptions and coverage
src/app/core/components/settings/configuration/config.component.ts, src/app/core/components/settings/configuration/config.component.spec.ts
Creation and duplication dialogs describe switching to the new profile and reloading. Duplication identifies the unchanged source profile. Tests verify both descriptions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Mergeability Score: 🔵 Low · up to f0fff

The PR makes newly created and duplicated profiles activate immediately while preserving queued changes before reload. It is mergeable with owner awareness because the tests should more strictly prove the drain ordering and verify that a profile remains visible and inactive when activation is deferred.

awaitQueueDrain reports false on a failed patch or a timeout, and its
own contract says callers treating a drain as a save guarantee must
check the result. The switch path logged a warning and reloaded anyway,
which discards the queue: the user lands on the new profile with no
sign that the last edits to the old one never reached the server.
deleteProfile already treats the same signal as an error.

A created slot survives the cancellation as an inactive profile, which
the refreshed list already shows.

Review addressed — f0fffc09

All three CodeRabbit findings taken. One of them changes behaviour beyond the PR's original scope, which is called out below.

Major — activation proceeded after a failed drain (profile.service.ts:78). activate() now throws instead of logging a warning. The finding is right, and the codebase already agreed with it in two places the review did not cite: awaitQueueDrain's own doc says callers treating a drain as a save guarantee "must check the result rather than assume success", and deleteProfile throws on the identical signal at profile.service.ts:205. The switch path — the one where the loss is unrecoverable rather than a lingering orphan — was the outlier.

This is a pre-existing behaviour change: switchProfile warned-and-reloaded before this PR too. It is in scope because the PR restructured that code into activate() and put two new callers behind it. A created slot survives the cancellation as an inactive profile; refresh() runs before activate(), so the list already shows it.

renameProfile keeps its warning. Its false drain means an orphan copy of the old slot, not a lost edit, and blocking a completed rename on that would be the worse trade.

Minor — drain tests could not distinguish awaited from fired-and-forgotten (profile.service.spec.ts). The ordering assertion is now a deferred drain: the promise is held open, setActiveProfile is asserted absent, then it is released. It passed against the existing implementation, so it is a regression guard rather than a bug find. Three false-drain cases added, one per path; the create case also asserts setConfig still ran, since the slot must survive as an inactive profile rather than disappear.

Minor — dialog assertions were partial (config.component.spec.ts). Creation asserts switches to it and reloads; duplication asserts left untouched, switches to the copy, the source name, and reloads. Not whole-string comparison: that turns every copy edit into a test edit and reports "string differs" instead of naming the promise the dialog stopped making.

Verification

npm run ci clean. 2 103 unit tests, up from 2 100 — the three false-drain cases; the deferred-drain test replaced the call-order one rather than adding to it.

The deferred-drain test flushed a single microtask, which lands while
createProfile is still inside its first refresh -- nowhere near the
drain -- so an implementation that fired awaitQueueDrain without
awaiting it passed. Gate on the mock being entered instead, and hold
the drain open across a macrotask.

The cancellation tests asserted the write happened but not that the
user can see the profile it produced. The listing mock now reflects
what was written, so they assert the inactive profile is on screen.
