#986 Edits disappear - then reappear mysteriously


I was editing [[Template:July 4 selected anniversaries]],
and after editing it, the old version directly preceding
mine disappeared, thus causing me to be credited with
its edit. About 5 minutes later, it reappeared just as

I took screenshots of these two versions of the pages.
The offending edit is the second from the top, titled "a
more dynamic, patriotic image to rotate on July 4".

    Ok, this is definitely *not* a caching issue, since the just-made edit is

    It might be some kind of weird locking/transaction delay on the old table
    hiding the previous edit for a bit while the cur table separately shows its
    having been updated... yuck.

    I had the same thing in the german Wikipedia wit the article
    [[atom]]. In my edit I remove an image on top of the text
    which was inserted by the editor just before my. I did not
    wait until the entry reappeared but several hour later after
    new login all entries were present.

    I just did some experiments: The problem arises if you add
    an image. It can be provoked doing the following step:

    1. Open an empty page, add an image and save.
    2. Edit this page again for an arbitrary edit (delete the
    image) and save.

    Then in the history the first edit is not present. In all cases
    mentioned above images were added before.

    I experienced a disappearing (but so far non-reappearing)
    edit on the article "I've fallen and I can't get up"
    (seriously). An IP address made a small edit on July 2, and
    I followed it up with another small edit to the same part of
    the article the next day; immediately after, when I checked
    out the article history, the July 2 edit had vanished, and a
    "last" on my edit shows a combination of my edit and the
    previous one (the diff between my version and the pre-July 2

    It's most likely a replication issue. Those should be
    solved by the replication synchronization code Tim added.

    Is this problem still there?
