Some minor bugs on Codeforces
By z4120, history, 4 years ago, In English

  1. This hack has been in queue for two weeks. https://codeforces.com/contest/1335/hacks

  2. (also on that page) The time is not localized.

    Actually this is not a bug, just a missing feature.

  3. On the "Complete problemset" page, the Codeforces logo is not updated.

    Example: https://codeforces.com/contest/1343/problems -- image:

    The logo should be this one.

    I thought this is because of caching, but the response header is cache-control: private,no-cache,no-store,max-age=0,must-revalidate.

    For comparison, the brand logo is displayed correctly on the "complete problemset" page of the contests such as Kotlin heroes.

  4. When a tag is duplicated while posting a blog, this error will appear.

    Just a little annoying. Codeforces already have the draft feature, which saves the post content.

submission will only show hacked instead of hacked by [user] if you are not logged in

if a solution get WA on test x it will show running on test x for a long time

comments sometimes show 0 instead of its real vote count

online x hours ago is not correct

there is still a speacial character in the content of [copy] code

submission time doesn't show according to user's time

out of contest participant on standing page doesn't show AC in how many second but in real time

    Maybe it's rerun after a few seconds?

    It's intentional, see this blog: "Now the negative score is not shown (just 0) if it is in range [-5,-1]. "

    submission will only show hacked instead of hacked by [user] if you are not logged in

    It's a reported problem -- unfortunately it may be an intentional feature.

    there is still a speacial character in the content of [copy] code

    I've already reported it (the bug happens when there's a new line at the end of the code. Example submission), but it remains unfixed.
