Expose a store API for the unified license key - #189
Conversation
Every licensing function in the registry is a read, so a host plugin that collects a key on its own onboarding screen has no supported way to hand it to Harbor. The only PHP that stores one is License_Manager, which a consumer would have to reach into through its own Strauss-prefixed copy — exactly what this API exists to prevent. lw_harbor_store_unified_license_key() validates the key against the portal before storing it, so callers keep the "that key was rejected" answer the REST endpoint gave them. It refuses when a key is already stored, and never replaces one. The guard has to run before the API call rather than after: validate_and_store() writes the key unconditionally on success and fires the changed action that wipes the cached products, so a check placed afterwards would be reporting on a key it had already destroyed. Cheaper, too — a redundant store now costs no HTTP request and none of the rolling failure budget that gates the whole site's activation flow. The bool return collapses "already stored", "rejected" and "the call failed", so both failure branches are logged: consumers that need to tell the first apart can check lw_harbor_has_unified_license_key() first.

📝 WalkthroughWalkthroughAdds ChangesUnified license key API
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to Concurrent onboarding requests can cause the newly exposed API to replace one valid license key with another, violating its promise to never overwrite an existing key and potentially leaving the site activated against the wrong license. Merge should wait until the duplicate check and write are atomic. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

- Around line 40-53: Replace the preflight key_exists() guard in the unified
license-key storage flow with an atomic conditional write in the licensing
repository or manager, so validate_and_store() rejects the operation when an
applicable site or network key exists at commit time. Preserve the existing
refusal result/logging behavior, and add concurrent-request coverage using two
different valid keys.

I wonder if we should name this lw_harbor_maybe_store_unified_license_key() instead?
With it named as just "store", I would expect it to always store the key and overwrite one if it exists.
But since this only stores one if a key doesn't exist, then using the WP convention of "maybe" I think could be helpful here going forward.

Why not just read/delete from License_Repository normally? This way if License_Repository changes how it reads the Unified Key in the future, this Test can properly determine if that change broke something. If we make raw read/write/delete that coupling is lost.
Everything you're trying to do here are public methods on that object.

Same concerns here. I don't like us manually clearing this state using delete_option() when we're not actually testing License_Repository directly. We should instead call License_Repository's own methods to delete it.

The one part i'm concerned about here is how much of this logic are we duplicating across services? We have the REST License_Controller.php, the CLI command src/Harbor/CLI/Commands/License.php - is there an opportunity to share logic or are they genuinely different enough to only pull in specific pieces?

Closing this ticket as we don't need it anymore in favour of the existing REST API endpoint provided in harbor https://github.com/stellarwp/harbor/blob/main/src/Harbor/API/REST/V1/License_Controller.php Discussion can be found here: |
