epriestley 9181929ebc Give files uploaded to objects a very restrictive view policy ... Summary: Fixes T4589. This implements much better policy behavior for files that aligns with user expectations. Currently, all files have permissive visibility. The new behavior is: - Files uploaded via drag-and-drop to the home page or file upload page get permissive visibility, for ease of quickly sharing things like screenshots. - Files uploaded via the manual file upload control get permissive visibility by default, but the user can select the policy they want at upload time in an explicit/obvious way. - Files uploaded via drag-and-drop anywhere else (e.g., comments or Pholio) get restricted visibility (only the uploader). - When the user applies a transaction to the object which uses the file, we attach the file to the object and punch a hole through the policies: if you can see the object, you can see the file. - This rule requires things to use ApplicationTransactions, which is why this took so long to fix. - The "attach stuff to the object" code has been in place for a long time and works correctly. I'll land D8498 after this lands, too. Test Plan: - Uploaded via global homepage upload and file drag-and-drop upload, saw permissive visibility. - Uploaded via comment area, saw restricted visibility. - After commenting, verified links were established and the file became visible to users who could see the attached object. - Verified Pholio (which is a bit of a special case) correctly attaches images.
