Summary: Error logs when diffing old revisions whose attachment content is missing
Issue Type: cid:jira-generated-image-avatar-4324d593-cdc0-4e64-bf13-55248abcb708 Bug
Affects Versions: 11.3
Assignee: Unassigned
Components: Old Core
Created: 02/Jun/26 10:15
Priority: cid:jira-generated-image-static-major-6e9bf39c-3ed9-4e96-94f9-75dedb02b6c2 Major
Reporter: Manuel Leduc
Description:

Reproduction steps

Variant A — delete + purge (recycle bin enabled)

  1. Create page Test.ReproDiff.
  2. Attach image.png (note the version, e.g. 2.1).
  3. Edit to insert the image in the page content
  4. Delete the attachment (it goes to the attachment recycle bin).
  5. Go to the deleted attachments tab of the page index and permanently delete the attachment
  6. Open the changes viewer between two early revisions: /xwiki/bin/view/Test/ReproDiff/?viewer=changes&rev1=4.1&rev2=2.1

Variant B — attachment rename/delete + page move

  1. Create a page P
  2. Attach a.png,
  3. Insert the image in the page content
  4. Rename a.png → b.png (or simply delete a.png). 
  5. Move/rename the page P → Q.
  6. Diff two old revisions (now served from Q) that both reference a.png: /xwiki/bin/view/<Q>/?viewer=changes&rev1=4.1&rev2=2.1

Order matters: the attachment delete/rename must happen before the page move. 

Expected

  • The changes/diff page renders without any ERROR in the logs.
  • For the attachment whose content can no longer be read, the diff shows the "The content diff is not available…" message introduced by XWIKI-15805 (web.history.changes.attachment.notAvailable), instead of failing the comparison.
  • When the content is still present in the recycle bin (Variant B), it should be recovered and the real content diff shown.

Actual

  • The page still renders, but for each affected attachment the log gets a full stack trace at ERROR level:
