fix(index): clean up indicies DB rows on all physical delete paths

[fabrizzio-dotCMS]

Summary

Fixes #35306 — ContentletIndexAPIImpl.delete() physically removed the index from the search provider but never deleted the corresponding row from the indicies table.

After a successful physical delete, a stale DB entry would remain pointing to a non-existent index, which could cause startup failures or silent inconsistencies on the next boot.

Root cause

The bug only occurs when delete() is called on an active index without a prior deactivateIndex() call (e.g., direct REST call to DELETE /api/v1/esindex/{name}). In the normal UI workflow, deactivateIndex() clears the DB row via point() before delete() is called, so no orphan is left.

Fix

After a successful physical delete, versionedIndicesAPI.removeByIndexName() is called to clean up the indicies row.

Phase safety:

• Physical delete: indexAPI resolves to IndexAPIImpl (the phase-aware router) — fans out to ES, OS, or both depending on the active migration phase.
• DB cleanup: versionedIndicesAPI.removeByIndexName() issues DELETE FROM indicies WHERE index_name = ? OR index_name = ? (bare + os:: tagged forms), covering both legacy non-versioned rows (ES, phases 0/1/2) and versioned OS rows (phase 3) in a single call. The deprecated legacyIndiciesAPI is not involved.

Test plan

• DELETE /api/v1/esindex/{name} on an active index → row removed from indicies table
• DELETE /api/v1/esindex/{name} on an already-deactivated index → no error (row already gone, removeByIndexName is a no-op)
• Verify across all phases (0, 1, 2, 3)

Findings

Two of the three paths described are not actually fixed.

The PR title is "clean up indicies DB rows on all physical delete paths" and the PR body lists a table of three call paths. Only one is fixed in the actual diff:

Path	Fixed?
ContentletIndexAPIImpl.delete()	✅
IndexAjaxAction.deleteIndex()	❌
DeleteInactiveLiveWorkingIndicesJob	❌

IndexAjaxAction.deleteIndex() (IndexAjaxAction.java:142-147) still calls APILocator.getESIndexAPI().delete(indexName) directly — the PR says it was rerouted through ContentletIndexAPI.delete(), but it was not. Same file, same line, unchanged.

DeleteInactiveLiveWorkingIndicesJob (DeleteInactiveLiveWorkingIndicesJob.java:23-24) still calls APILocator.getESIndexAPI().deleteInactiveLiveWorkingIndices(...) with no DB cleanup. The PR says ESIndexAPI.deleteInactiveLiveWorkingIndices() now returns List<String> and the job iterates it — it still returns void and nothing iterates anything.

Neither file appears in the changed files list. The PR title, description, and summary table describe a scope that was not implemented. Fix this →

The regression test proves nothing.

createContentIndex(workingIndex) at ContentletIndexAPIImplTest.java:312 calls the public synchronized overload (ContentletIndexAPIImpl.java:551) which only creates the physical ES/OS index — it never writes to the indicies table. So the SELECT COUNT(*) FROM indicies WHERE index_name = ? assertion at line 380 will always return 0 regardless of whether removeByIndexName is called. The test passes identically before and after the fix.

To make it meaningful, the test needs to seed the indicies table first (e.g., call versionedIndicesAPI.saveIndices(...) or INSERT INTO indicies directly), then verify the rows are gone after delete(). Fix this →

Minor: unused variable in IndicesFactoryImpl.removeExistingIndicesForVersion()

IndicesFactoryImpl.java:319: final int deletedCount = dotConnect.executeUpdate(...) — deletedCount is declared but never read. Minor compiler warning / dead code.

---

The fix itself (ContentletIndexAPIImpl.delete()) is structurally correct — physical delete first, DB cleanup only on success, failure logged but not re-thrown so the caller still gets an accurate boolean. No other issues with the new removeByIndexName plumbing (IndicesFactory, IndicesFactoryImpl, VersionedIndicesAPI, VersionedIndicesAPIImpl).
