How can a post have an overall score of +1 with 0 up and 1 down votes?

Iphone resource file size limit

Notwithstanding the answer itself, I see 0 vote up, 1 vote down, and a final score of 1.



Sum Expanded

Steps to reproduce:

  1. Find a post with vote +0/-0.
  2. Vote up
  3. Cancel up-vote
  4. Refresh the page to see it reports a total vote of 1, and the vote splitting becomes +0/-1.


So now the votes are 0 up, 0 down. We can infer from the timing allowed on vote cancellation that in some cases, a single up-vote, cancelled, produces a "temporary down-vote" which is cached and doesn't get removed for about a day. The sum total of votes remains unchanged post cancellation (and thus erroneous) and the vote detail is also erroneous.

  • Jeff Atwood's answer here: meta.stackexchange.com/questions/68737/… gives this same problem. – Yi Jiang Oct 28 '10 at 13:57
  • This is a remnant of the outage a week or two ago. It's been reported numerous times. Looking for links now... – Pops Oct 28 '10 at 14:12
  • @PopularDemand. Thanks. I wonder how a week-old outage can change the laws of mathematics today, though. – MPelletier Oct 28 '10 at 14:19
  • @MPelletier, I misunderstood your initial post. I thought you were referring to the question, posted in September, not the answer, posted today. That's double-odd. I don't know enough about how the SE databases work ("But you don't know anything about how the SE databases work!" "Exactly!") to know if the same corrupted-database-denormalization-voodoo-magic could be responsible. – Pops Oct 28 '10 at 14:32
  • Guys, I do not know what you are doing here, but this was discussed several times and you should already know, that it is a caching issue. At least, that's what Jeff says. No, I'm too lazy to search all these dupes. Ok, ok, here is one: meta.stackexchange.com/questions/67592/… – Ladybug Killer Oct 28 '10 at 14:52
  • @LadybugKiller: Thanks. Though it seems to correct itself over time, a case could (I didn't say should) be made for correcting this issue. – MPelletier Oct 28 '10 at 15:10

    This bug affects only 1-rep posters. – kennytm Oct 28 '10 at 15:32

    @MPelletier: Turns out it does not affect only 1-rep posters, but people who cast the first vote. I have updated your reproduction procedure to make it clear. – kennytm Oct 28 '10 at 17:44
  • @KennyTM: So the downvote doesn't even exist?? Wow! – MPelletier Oct 28 '10 at 17:48
  • @sth: Gee, thanks! I don't know if that'll do it, though. – MPelletier Nov 1 '10 at 13:29

    @MPelletier: The power of the bounty! Instantly fixed and I did even got the bounty rep back. I should do this more often ;) – sth Nov 1 '10 at 17:08
