ChangesRedirect deduplication
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to Redirect creation now deduplicates by source path and language, but unresolved handling for an unavailable source path may trigger a runtime deprecation, and concurrent identical requests can still fail with a duplicate-record error. The change is mergeable with explicit owner awareness or follow-up for these bounded edge cases. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Validate parsed_source before hashing.
When getPath() cannot resolve $source, it returns NULL. createRedirect() passes that value to ltrim(), which can trigger a null-to-string deprecation on the supported PHP versions. Reject NULL before setting the entity and generating the hash.

Fixes https://www.drupal.org/project/filefield_paths/issues/3045063
Problem
Redirect::createRedirect()checked for an existing redirect using a hash built from the destination path, while\Drupal\redirect\Entity\Redirect::preSave()builds the stored hash from the source path and the entity's own language. The two values could never match, so the duplicate was never found and a second identical call died on the redirect table's unique index:Reported since 2019, confirmed by four people, and reproducible whenever the same file is moved twice, which happens routinely with Media Library and with Behat suites that reuse a source file.
Fix
Two commits, so the community fix keeps its author:
fix: #3569210 ...style commit by w.drupal, taken from patch test: comprehensive kernel and unit test coverage #7 on the issue: hash the source path, and set the entity's language so the pre-check and the stored hash agree.Both halves are required. Correcting only the hashed path fixes the default-language case and still crashes when the file's language is not the site default, which is the common case since the caller passes
$file->language().Verification
RedirectTest::testCreateRedirectTwiceWithSameArgumentsDoesNotThrowalready existed but was disabled behind a flag; it is now enabled and linked to the issue.RedirectTest::testCreateRedirectTwiceWithNonDefaultLanguageDoesNotThrowis new and covers the language half. Applying only the source-path change leaves this one failing, which is how the second half was proven necessary.Summary by CodeRabbit
