fix(#3494240): skip the redirect when a file leaves the staging location by Decipher · Pull Request #24 · Decipher/filefield_paths

Decipher · 2026-08-28T01:28:31Z

Relates to https://www.drupal.org/i/3494240. Follows the redirect source fix that landed as 8423c05; the two together close the junk-row bug found while setting up the 8.x-1.0-rc2 demo.

Problem

With "Create Redirect" and active updating on, every first save of a new upload created a redirect from the staging path to the final path. The staging path only ever existed between the upload and the save, so nothing could link to it, and the redirect table grew by one row per upload. Under rc2's temporary:// default the source of that row was also malformed, which 8423c05 fixed.

Fix

FileFieldPathsProcessFileLegacy skips the redirect when the file is still at the staging location, global or field level, before the move. A bare scheme root such as public:// is not treated as a staging location: used as a prefix it would match every file on the scheme and stop redirects being created at all. The settings form accepts a bare root, so this case is real.

Tests

StagingRedirectTest, five kernel tests: a new entity earns no redirect; an existing entity gaining a staged upload earns none; an existing entity whose file moves from a published path still does; a bare scheme root does not suppress redirects; a field level staging location wins over the global one. The test pins temp_location to public://filefield_paths because rc2 moved the install default to temporary://filefield_paths.

Commits

Two commits. The first is Sakshi Sharma's, from their merge request on the issue in 2024-12: no redirect when the entity is being created, remade on the current hook class because the line it changed has since moved out of filefield_paths.inc. The second is mine: no redirect when the file is only now leaving the staging location, which also covers an existing entity that gains an upload, plus the bare scheme root guard, the tests voleger asked for, and the changelog entry.

Summary by CodeRabbit

Bug Fixes
- Prevented redirects from being created when files move from a temporary staging location during initial or subsequent saves.
- Improved staging-location detection, including support for field-specific temporary locations.
- Bare scheme roots such as public:// are no longer treated as staging locations.
- File moves from published locations continue to create redirects as expected.
Tests
- Added coverage for staging uploads, published file moves, new entities, temporary URI schemes, and staging-location precedence.

📝 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, field-specific, and unregistered-scheme 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`, `CHANGELOG.md`	Kernel tests verify staged files, published files, global bare-root settings, field-level staging settings, and unregistered temporary schemes. The changelog records the redirect behavior.

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.
