Database Redesign

Post by Alkworld » Wed Sep 04, 2024 5:20 pm

Hi C4F community,

you might have read a couple of times that I was mentioning some mysterious redesign in the past month, which basically keeps me from fixing anything else. I'll try to explain why I'm doing that, what I'm doing (roughly) and what the next steps are.

Why am I changing something?
I need to be a little technical here: The database (which stores all user data, teams, riders, races and a lot more) is organized in tables, but unfortunately not in a very good way especially when it comes to riders and teams
  • the rider table contains rider info (name, skills, value, etc) and info about the rider's current race (energy, points, tempo settings, ...)
  • the team / user table contains user info (name, password (encryted), email address, language settings, etc), team info (balance, number of wins, etc) and info about the team's current race (salary, race ID, next race, etc)
  • retired riders are in a separate table
  • the transfermarket is split over three tables (above mentioned rider table, youth transfermarket and older riders transfermarket with generated riders)
  • the code for race calculation is seriously hard to understand, as it's not well structured and badly documented (no offense to Buhmann, he was still in school when writing it). Fixing bugs there is very tricky without extensive testing. And even then the impact of changes is far from obvious (see pavé fixes).
Having one table for active riders and their races now makes it hard to have multiple races for a rider (like short races in addition or world championships where riders are controlled by different users). Buhmann solved it by making copies of those tables, but this is a pretty ugly solution. The same goes for the users / teams table.

What am I changing now?
  • for all riders (active, retired, transfermarket), there will be one combined table
  • riders in races (called racers in the code) are handled in a different table
  • users, teams and teams in races will be separated (similar like riders and racers)
  • new test environment and better tools for admins to be able to help with the testing (lots of code needed to be changed, which possibly causes new errors)
Benefits of the changes
  • less technical dependencies with the seperation of rider and race data (shorter red light)
  • simpler code, easier to understand and maintain
  • other race types can be in parallel (short races, world championships, retired rider races, etc)
  • signing up for multiple races at a time will be possible
  • races (incl replay) can be available for a longer time
  • better online status solution (incl. sitters, auto-refresh and visitors again)
  • rebuilding the whole race physics will be easier (or even possible at all)
  • better performance, smaller database size, more robust game in general (it's not that bad currently)
Next steps
  • me completing the code (including taking over Gipfel's recent improvements)
  • testing the new code, new database setup and bugfixing --> here you (any player) will be able to help, too. I'll let you know by then.
  • at some point moving to the new version (maybe the game needs to be off for a few hours to migrate the data)

Hi everybody,

the new version is now ready to be tested, i.e. all the important features might work correctly, but maybe they aren't and I just haven't noticed. As the changes were that big, it's hard to notice if I missed out anything important.

You can reach the new version on http://cycling4freaks.com/c4f-3.0/c4f-react/, the picture on top is replaced by something ugly so you know you're not in the real (old) C4F. The data is a copy of the original data from a week ago (Andes is cancelled there), therefore you can login with your usual account details.

So if you're interested in finding any bugs there and help me finalizing the new version, feel free to test whatever you want and whatever comes to your mind. Areas that require a bit more testing are the following:
  • check if the transfermarket still looks fine and has the usual kind of riders (the code for generation of riders has been changed)
  • check various kinds of one-day races and tours, ITT, TTT, rest day, half stages, pavé. The core of the race code hasn't changed, but there's lots of translations between old and new data model
  • check if FPC functionality is complete and includes Gipfel's recent changes
  • check race editor and calendar planning tools
  • check nations committee functionality
  • check all the stats
If somebody is interested, I can assign the admin role in the test environment (max one or two people, as it could get chaotic otherwise), then you can test races a lot faster (day change and race calculation can be triggered). Same with the calendar planner role, which allows to publish races in the test environment.

Thanks for the effort, a view early observations:

- my 20 year old rider was not transferred to the new version
- non of the riders on the transfer marked are available, probably an error which div can buy them
- I still see the canceled races (10 h and 15 h) on the inscription screen (should check what happens with the 19 h race)

Data is from around day 2 of Andes, maybe last Sunday. Which rider is it?

I cancelled Andes manually, they are still shown because the calculated time is not over yet. New races are cancelled because nobody signed up :)

Norbert Wiener (ID 1209457). The transfer is shown under transfers but the rider is not shown in the rider list und Team.

quite some riders have missing flags in statistics tab, i assume because of mismatch of country codes



not a bug, but suggestion: when hovering over flags it would be nice to show the name of the country in the tooltip instead of "c4fcode" (teams page) or "nationality" (statistics)

for me it shows the market of riders on the transfer market as unknown instead of the Divs

Yesterday, Sieb in green looked way to effective. It was something like 50 against 41 climbing, 200 less energy, +11. The time difference looked too small for a normal split as well.

A few fixes done now (v3.0.1):
- team page in race corrected
- no more crash when sorting by number in inscriptions
- no more crash when sorting by acronym in stats (Hansa's "fault" with a number as acronym)
- winner interviews are shown again
- Race leads you to today's race after it's completed
- signing up for cancelled races is no longer possible
- fairplay votings working again (I didn't get a crash there)
- missing flags might be fixed (issue only in older browsers where unicode flags are not used)

At 1800 race there is only one rider from team bergwerk with starting number "-9". I don't think bw inscribed fully to the race

Riders stop tempo as soon as a team switches to yellow status (offline 3 kms) if you use auto refresh
