Separate 'Game Mode' - Push the button to survive

[geerlingguy]

UPDATE: Here are the requirements:

• [x] Make a front-end timers page which shows the current countdown live for each room.
• [x] Make that front-end page refresh the timing data via AJAX every second for all live rooms.
• [x] Make the back end have a URL that returns the live countdown amount for each room based on the current time, the increment (time_seconds) time, and the number of button presses for the room.
• [x] Run a process that ticks every 1000 ms (like this) and checks the state of every room. If any room is over time at all (delta is 0 or negative), UPDATE the room and set color = red and time_expired = 1.
• [x] Update the URL for production server inside refresh_timer_data() in timers.js before go-live!
• [x] Fix bug-ish thing: When saving changes on Overview page, rooms that are expired should not have a vote saved!
• [x] Highlight the fact that there's no real "pause" functionality for this game — workaround is to set the time to a high value once the game is over. That's why I set the opening round value to 59 minutes. Can also 'reset all timers' for any room that is 'live'.

Making some headway on this:

Have to get all timey-wimey and use some javascript wizardry to keep that countdown fresh though.

Gonna be a little rough doing it all real time :/

Disabling the button game on the production servers for now (one less thing to keep running).

At this point, very likely not gonna happen before go-live.

[geerlingguy]

And at this point, very likely to happen after go-live. Need to gather some requirements.

New frontend for timer countdown bit, at least...

[geerlingguy]

Just did a load test with the whole thing running, and got at least 1000 votes per second throughput with the frontend updating every second:

And I also traverse the dom like a madman to get all the classes set correctly via Javascript (and otherwise, the page refreshes and shows the latest data if JS is broken):

I've also added a 'force reset timer' functionality that turns a room 'on' again and saves a vote so you can see it's back active. This should be helpful for debugging, and for the case where someone's buttons just stop working, for whatever reason. They could kinda 'pause' the game for that room.

I don't have any other pause functionality, though. The game will continue pretty much forever, until all rooms are counted down to 0.

I added functionality to force reset ALL live room's timers:
