Revision wrongly flagged as "automatically checked" after edit conflict
Closed, ResolvedPublic

Description

See URL for an example.

Revision 97771495 is flagged as "automatically checked" though the previous version isn't. I think this is what happened:

  1. The base version is the version from 17:14 (CET), a flagged version.
  2. Elmar Nolte (with autoreview right) starts to edit.
  3. The IP starts to edit and saves first. The revision is not flagged.
  4. Elmar Nolte saves. The software detects an edit conflict which is resolved automatically. So no warning is shown. The FR extension still sees this edit based on the previous flagged version and flags the new revision as automatically checked.

But in fact Elmar Nolte's revision is based on the unflagged revision by the IP and should not be flagged automatically.

Was Elmar editing the page for 55+ seconds for such a small change? I suppose it's possible.

it's possible.

I think 55+ seconds for: starting link dialog from WikiEditor, messing around, inserting the link, clicking preview, testing the link, wondering why it doesn't work, deciding to save anyway is not very long, so definitely possible.

Are there any other known instances?

Are there any other known instances?

I tried to reproduce it on http://de.wikipedia.beta.wmflabs.org/w/index.php?title=Testseite&action=history, but apart from the fact that at first my login cookie get lost everything worked as expected. So I'm closing this bug for now.

Reopening: This happened again in https://de.wikipedia.org/w/index.php?title=Allgemeines_b%C3%BCrgerliches_Gesetzbuch&action=history

There are three relevant edits (all times in CEST):

(1) IP at 20:42:00
(2) IP at 20:42:31
(3) Botulph at 20:42:49

Edit (3) was started after (1), but before (2), and is just a revert of edit (1) via the "undo" function. The edit conflict with edit (2) was automatically resolved, but (3) was automatically checked, though of course it shouldn't.

Does this require VisualEditor to reproduce?

Neither edit is tagged as such, so no.
