Fedora QA implemented a blocker voting system using Pagure tickets:
https://pagure.io/fedora-qa/blocker-review

Each time a person sends a comment containing a vote (e.g. BetaBlocker +1), our bot intercepts the message, computes the current votes, and updates the ticket summary. This happens very fast, in a matter of seconds after the user vote was submitted.

The current problem is that each person who casts a vote needs to refresh the page manually again, to make sure their vote was counted (it wouldn't be counted if they made a typo, for example). That's tedious to do every time. People would like to see the effect happen automatically.

We would like Pagure to automatically refresh the ticket description, it if gets changed, for everyone having that page currently open in their browser.

Please note that it seems that Pagure maybe already attempts something like this already. Sometimes, after sending a comment, the ticket description changes to a "mess of characters" - something that appears to be a single line of unformatted characters. (I couldn't reproduce it right now, but when I can, I'll attach a screenshot). My guess is that the ticket description gets updated and Pagure tries to reflect that, but it doesn't reformat that using Markdown, and instead displays it as raw text (with linefeeds munched?). But this happens only sometimes, in other cases I see no change in the description. So it might be some race, a different bug, I don't know.
