Fixes https://www.drupal.org/project/filefield_paths/issues/3494240

Problem

Every new media entity left a redirect behind, pointing from the upload staging path to the final path. That path only exists between the upload and the save, so nothing can ever link to it. The result is redirect tables filling with entries that can never be followed.

Fix

Skip redirect creation when the file is only now leaving the staging area, resolved from the field's own temp_location third-party setting, falling back to filefield_paths.settings:temp_location, which is exactly where the widget puts uploads.

A bare scheme root such as public:// is treated as "not staged". The settings form accepts one, and used as a prefix it would match every file on the scheme and suppress redirects site-wide.

Notes on the existing patch

MR !32 on the issue guards on $entity->isNew() && isset($entity->original). That cannot work as written: core clears the new flag before invoking hook_entity_insert, and keying on the original also suppresses legitimate redirects when a previously published file is attached to a new entity and then moved. Credit to sakshi17 for the report and the diagnosis.

Verification

StagingRedirectTest covers four cases: staged upload creates no redirect, a genuinely published file still does, a bare scheme root does not suppress, and the field level staging location takes precedence over the global one.

Review Change Stack

📝 Walkthrough

Walkthrough

The file processing hook now detects staged uploads before creating redirects. It resolves field-level or global staging locations and adds kernel tests for staged, published, bare-root, and field-specific paths.

Changes

Staging-aware redirects

Layer / File(s) Summary
Redirect detection and staging-path resolution
src/Hook/FileFieldPathsProcessFileLegacy.php
The hook receives ConfigFactoryInterface, resolves the staging location, rejects empty or bare scheme-root paths, and skips redirects for staged uploads during active updating.
Kernel coverage for redirect behavior
tests/src/Kernel/StagingRedirectTest.php, tests/src/Kernel/FileFieldPathsProcessFileLegacyTest.php
Kernel tests verify redirect behavior for staged files, published files, global bare-root settings, and field-level staging settings. Existing constructor setup passes the config factory service.

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

Merge Risk: 🟡 Moderate · up to 63a2f

When active updating is disabled, the change can omit redirects for files that are moved from an already published location, leaving old URLs without the expected redirect. Merge should wait for this behavior to be corrected and tested.

Preserve redirects when active updating is disabled.

When a new entity references public://published/... and active_updating is disabled, the hook still moves the file. The added prerequisite then skips the redirect. Remove it and let isStagedUpload() suppress redirects only for staged files. Add a kernel test for this configuration.

Checked this against the pre-PR code, and the finding is real but it is not introduced here.

The active_updating requirement on the redirect predates this branch. At d23f47e2, before any change of mine:

// Create redirect from old location.
if (
  !empty($settings['redirect']) && $settings['active_updating'] &&
  $this->moduleHandler->moduleExists('redirect')
) {

This PR adds only the !$this->isStagedUpload(...) clause. So the case you describe, a new entity referencing public://published/... with active_updating disabled, already moved the file and already skipped the redirect before this change. Removing the active_updating requirement would be a behaviour change to a separate documented setting, widening when redirects are written, which is beyond a fix scoped to https://www.drupal.org/i/3494240 and wants its own issue and its own release note.

Worth saying that the underlying observation looks sound to me: if the module moves a file away from a path that was publicly reachable, a redirect is the right outcome regardless of the active_updating setting, and the current coupling of the two settings is questionable. I am raising it separately rather than folding it in here.

For what this PR does cover, StagingRedirectTest pins all four paths: staged upload leaves no redirect, a genuinely published file still gets one, a bare scheme root does not suppress scheme-wide, and the field level staging location takes precedence over the global one.
