Rapidly spamming/deleting comments can break "infinite river" feature on comment moderation pages

[markjaquith]

Comment moderation pages have an "infinite river" feature whereby when you remove one comment (spam/delete), it'll load a new one at the bottom. Unfortunately, it doesn't seem to catch up if you click more rapidly than about once every 2 or 3 seconds, and you'll "lose" comments. At the end, you may just have one comment that, when dealt with, will be replaced by only one comment. This may have to do with doubleclicking the "spam" link, or maybe clicking the "spam" link of the next comment before the river action has finished.

Does this bug still apply ?

[markjaquith]

Yes. This bug applies even more strongly now that there is keyboard-based moderation.

I believe the main problem of this bug has to do with your connection speed to the server.

When you click, the javascript hides the comment, the request (A) is send to the server.
You click another comment, the javascript hides the comment, the request (B) is send to the server.
But if you have a slow connection to the server, Request (A) might not have finished yet and is terminate. The server won't handle the actual spam/delete Request (A).
When you do this multiple times, the queue that has the overflow of comments is depleted and doesn't fill up because of the terminated requests.

Turns out I have no desire to work on this - I'd rather wait until we overhaul the whole thing.

There doesn’t seem to be a clear solution suggested, but I think this can at least get moved back into “Future Release"
