Fixed the React editor saving from a stale copy of the post - #31278
Conversation
|
Navigate logical layers of code changes, visualize relationships, and explore their blast radius. WalkthroughThe editor session now exposes feature-image alt text and caption and adopts eligible values from reads and save acknowledgements. The feature-image binding uses session values and defers caption updates while the writer edits. The editor hook writes acknowledged records to the screen’s read query unless a later version is cached. The acceptance helper waits for the matching query to become idle. New tests cover feature-image synchronization, save acknowledgements, cache updates, and reopening the editor during a held refetch. Priority: ➖ Normal Change: Bug fix Merge Risk: 🟡 Moderate · up to Another writer's feature-image alt text or caption can be overwritten by this writer's older save. The overwrite can happen in the editor's working copy and in the cached copy used when reopening. A later save can then send the stale text back to the server. These issues should be resolved before merging. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The examined changes preserve record identity checks, local-edit protection, and precedence for newer saved content. No introduced security issue was established, but authorization and safe handling of server-supplied caption HTML were not fully verified.

no ref After a save the editor refetches the post, and a post reopened before that read landed was built from the copy cached before the save. The read then carried a newer token, which the session only adopts at the token it holds, so the next save raised a false "Someone else is editing this post" banner against the writer's own save. Each acknowledged save now writes the server's answer into the editor's query cache, as a reload already does, so a reopen starts from the saved copy. The acceptance helper that waits for a read now waits for the read itself rather than that copy.
no ref A read of another writer's later version could land in the editor's query cache before this tab's save answer, which then overwrote it, so a reopen showed the older version and its next save raised a false conflict. The answer now leaves a later cached version alone, by the comparison a reload already makes. A caller that throws on the answer is reported instead of failing a save that has landed, and a spec's held reads are released when it finishes.

#31279) no ref Another writer's alt text or caption edit doesn't move the post's version token. When a read brought that edit in, this writer's editor turned dirty, and their next save silently reverted it. - Another writer's alt text and caption now show in the feature image field and survive this writer's next save. - Typing in either field builds on their value. A caption the writer is typing in updates once they leave it. - The writer's own alt or caption edit still wins.
