live-v3's Introduction

live-v3

Welcome to the ICPC Live Source Code Repository.

Run release version

Download release from https://github.com/icpc/live-v3/releases
- You can download latest dev build instead if you are brave enough
Create contest config files
(Optional) Tune imported data, so it looks better
Run java -jar /path/to/jar/file --config-directory=/path/to/config/directory

Check for more options by running java -jar /path/to/jar/file without arguments. Here is the couple most useful
- --creds=creds.json -- The path to the credential file. It can be used to avoid storing credentials in the main config file.
- --no-auth -- Disable auth in admin interface. It's useful if you are running the overlayer on localhost.
- -p 8080 -- 8080 is default port to listen, but it can be changed.
- --widget-positions=filename -- customize positions of each widget, see examples in config/widget_positions.json.*
- --visual-config=filename -- customize colors, sizes, captions and other, see examples in config/visualConfig.json.*
(Optional) Check imported contest data
Add a source to OBS
- +Source
- Browser
- URL http://localhost:8080/overlay?noStatus
- W H 1920x1080
- OBS Custom css:
```
#root > div {
    background: unset;
}
```
Use admin interface in your browser to control overlay
Check general broadcast production schema for other details of typical setup
Check emulation mode part of development doc for testing your setup before the contest started.
Check troubleshooting guide is something looks wrong.
Read our awesome auto-generated documentation for extensive settings.json and advanced.json usage.

Authorisation

For now http basic auth is used. If you try to login with user, which does not exist, it will be automatically created. First created receives admin rights. Others only receive them when someone with admin rights confirms, it's okay.

Consider, if you are okay with passing your passwords using plain HTTP.

If you don't need auth, you can disable it by --no-auth command-line option.

live-v3's Issues

Overlay. Scoreboard Row doesn't expect undefined in scoreboardData

live-v3/overlay/src/components/organisms/widgets/Scoreboard.js

Lines 133 to 150 in 34fdc7a

 export const ScoreboardRow = ({ teamId, hideTasks, rankWidth, nameWidth, sumPenWidth, nameGrows, optimismLevel }) => { 

 const scoreboardData = useSelector((state) => state.scoreboard[optimismLevel].ids[teamId]); 

 const teamData = useSelector((state) => state.contestInfo.info?.teamsId[teamId]); 

 return <ScoreboardRowContainer> 

 <RankCell rank={scoreboardData.rank} medal={scoreboardData.medalType} width={rankWidth ?? SCOREBOARD_RANK_WIDTH}/> 

 <TeamNameCell teamName={teamData.shortName} width={nameGrows ? undefined : (nameWidth ?? SCOREBOARD_NAME_WIDTH)} canGrow={nameGrows ?? false} canShrink={nameGrows?? false}/> 

 <ScoreboardStatCell width={sumPenWidth ?? SCOREBOARD_SUM_PEN_WIDTH}> 

 {scoreboardData.totalScore} 

 </ScoreboardStatCell> 

 <ScoreboardStatCell width={sumPenWidth ?? SCOREBOARD_SUM_PEN_WIDTH}> 

 {scoreboardData.penalty} 

 </ScoreboardStatCell> 

 {!hideTasks && scoreboardData.problemResults.map(({ wrongAttempts, pendingAttempts, isSolved, isFirstToSolve }, i) => 

 <ScoreboardTaskCell key={i} status={getStatus(isFirstToSolve, isSolved, pendingAttempts, wrongAttempts)} 

 attempts={wrongAttempts + pendingAttempts}/> 

 )} 

 </ScoreboardRowContainer>; 

 };

We can't expect that scoreboardData in ScoreboardRow isn't undefined also as in QueueRow

live-v3/overlay/src/components/molecules/queue/QueueRow.js

Lines 24 to 37 in 34fdc7a

 export const QueueRow = ({ entryData, isEven }) => { 

 const scoreboardData = useSelector((state) => state.scoreboard[SCOREBOARD_TYPES.normal].ids[entryData.teamId]); 

 const teamData = useSelector((state) => state.contestInfo.info?.teamsId[entryData.teamId]); 

 const probData = useSelector((state) => state.contestInfo.info?.problems[entryData.problemId]); 

 return <QueueRowWrap> 

 <RankCell width={CELL_QUEUE_RANK_WIDTH} isEven={isEven} rank={scoreboardData?.rank} medal={scoreboardData?.medalType}/> 

 <TeamNameCell teamName={teamData?.shortName ?? "??"} isEven={isEven}/> 

 <Cell width={CELL_QUEUE_TOTAL_SCORE_WIDTH} isEven={isEven}> 

 {scoreboardData?.totalScore ?? "??"} 

 </Cell> 

 <ProblemCell probData={probData} width={CELL_QUEUE_TASK_WIDTH} isEven={isEven}/> 

 <VerdictCell verdict={entryData} width={CELL_QUEUE_VERDICT_WIDTH} isEven={isEven}/> 

 </QueueRowWrap>; 

 };

bug: before for CDS is 24 hours minus remaining time instead of negative time

tracked on SWERC. Recorded on Lidia's computer.

CDS pause and restart works though

Incorrect captions in info widget

Move ticker for TA live to main project. Multiline scoreboard, for example

feat: allow usage of locally hosted of images from Titles view

Feature description

Right now, images are required to be hosted via some external URL. Make it possible to use self-hosted images.

Motivation and possible use case

Two scenarios - one is that you are running a contest locally and cannot connect externally for some reason. Another is that you don't want assets to be publicly accessible at all.

bug: Team names are not rendered right away anywhere

feat: admin widget preview

Add widget preview to admin interface

feat: Add zebra for scoreboard

Think about the time when submits are in the queue

With a large number of submits, they do not fit, it does not look very good.

Perhaps it is necessary to hide them faster, since breaking news may not fit.

Grabbing contestant screens with webrtc

Rewrite overlay components to be used independently of redux state

This will allow us to ebmed components in the admin page

Team names appear late in scoreboard and ticker

feat: scroll last scoreboard page partially

To make scoreboards with little remainder nicer, we can just scroll the last scoreboard page for the remaining number of lines. Will look super nice for two-page scoreboards

Scoreboard settings don't work correctly

Try showing pages from 1 to 2

feat: Allow to have noop cds

Feature description

It should be possible to run overlayer with noop CDs, which will produce empty contest

Motivation and possible use case

Sysops were unhappy we were querying CDs after the closing ceremony because they were not sure if they can disable it.

feat: filtering for teamView

В инфо хочется несколько режимов - показать все решенные, показать все задачи которые трогали. Я бы ещё подумал над тем, чтобы показывать последние несколько попыток. (?)

Problems with statistics widget

Backend: Incorrect location
Frontend: Don't work correctly after freezing the results

Rework advanced properties and hot reloading

Add mapping from hot reloading structure to partisipant xml.

List with team ids (may be in contest.xml) (it's immutable).

Mutable list with special data (team video urls, team and cute full names, special start time).

bug: Build results in StackOverflowError

Context (Environment)

Trying to build the application using ./gradlew build or running using ./gradlew run.

Expected Behavior

The build succeeds without an error, and its possible to run ./gradlew release afterwards and use the resulting jar, or run the application.

Current Behavior

When running ./gradlew run or ./gradlew build, the build results in a java.lang.StackOverflowError, failing the build. Full logs: https://gist.github.com/kokx/ca709aebf3f8274235d78bfa81f43019

Possible Solution

Removing sniper-tools from from the include in /settings.gradle.kts allows the build to succeed.

Steps to Reproduce

Run ./gradlew build
For more information, see the logs in https://gist.github.com/kokx/ca709aebf3f8274235d78bfa81f43019

feat: scorebord type display

feat: Show submission language

Show submission language in queue

Feature description

We could show the programming language for runs in queue.

Motivation and possible use case

I think some viewers are wondering — what languages the contestants are using.

feat: Admin refetch admin data on data change on backend

Feature description

Refetch data when someone else edits the settings

Motivation and possible use case

It might be confusing when multiple users are editing presets and someone else changes them

Add authorisation (HTTP Basic Auth)

Passwords not in repos may be

More intresting statistic. For example, languadges statistic by problem or all submissions, avg submissions conunt by problems, avg testing time by problems

bug: fix statistics widget location

Статистика в кривом месте. Также кажется что она не согласована с таблицей результатов, особенно после заморозки

bug: Playwright tests are failing in GitHub Actions

Recently, playwright tests stopped working in GitHub Actions.
Example: https://github.com/icpc/live-v3/actions/runs/9149700885/job/25153716677

feat: expand show button

Optimistic and pessimistic scoreboard and caption

bug: Statistics with >=M problems gets out of widget borders and only shows L problems

Test: any contest with >=M problems

Existing result: only shows first L problems

Expected -- Change statistics widget into larger rectangle (same as scoreboard) and align bottom

bug: Locator doesn't dim good enough

Manage css styles in live (we haven't rebuild all to change gold medal color)

feat(backend): save current showing widgets in a file

MIT Licence & Open Repo

bug: Scoreboard scrolling works strange, when teams appearing while scoreboard is shown

You can check it by enabling

{
  "scoreboardOverrides": {
    "showTeamsWithoutSubmissions": false
  }
}

in advanced settings.

Get rid of Redux in favor of something faster

bug: Same team being showed multiple times in splitscreen when spamming in chat.

bug: statistics: Don't work correctly after freezing the results

Needs steps to reproduce

feat: Add keyboard shortcuts to admin

В целом мышкой пользоваться довольно неудобно - много маленьких кнопок. В будущем хочется вообще задавать админке system-wide сочетания клавиш, чтобы можно было на микро-стимдек мапить.

@azat-ismagilov

feat: quick buttons in admin to show split top4, pvp top 2 and so on

bug: left ticker needs to adjust text to width

Test on BSUIR OPEN

Default random task colors on frontend if none were passed

Rework scoreboard admin

bug: vmix ignores thinning the font in queue

https://vk.com/video/@moscowicpc?z=video-44001716_456239210%2Fclub44001716%2Fpl_-44001716_-2

Appeared on Rucode stream.

Only in queue, scoreboard is fine.

Longer team names move the number of problems, problem and verdict cells to the right

Correct events loading in clics contest emulation

Merge may give not all events here

live-v3/backend/src/main/kotlin/org/icpclive/cds/clics/ClicsDataSource.kt

Lines 158 to 175 in 5804875

 override suspend fun loadOnce() = coroutineScope { 

 val (_, contestInfoFlow, analyticsEventFlow) = launchLoader() 

 val analyticsEvents = merge(contestInfoFlow, analyticsEventFlow) 

 .takeWhile { it !is ContestInfo || it.status != ContestStatus.OVER } 

 .fold(mutableListOf<AnalyticsEvent>()) { ac, it -> 

 when (it) { 

 is AnalyticsEvent -> { 

 ac += it 

 ac 

 } 

 else -> ac 

 } 

 } 

 val contestInfo = contestInfoFlow.first { it.status == ContestStatus.OVER } 

 coroutineContext.cancelChildren() 

 val runs = model.submissions.values.map { it.toApi() } 

 ContestParseResult(contestInfo, runs, analyticsEvents) 

 }

It would also be nice to have single commentary message overlay. Similar to how social media comment overlays look like in similar tools.

feat: Show what task the team is working on

Show what task the team is working on
Think of a way to show it pretty.

bug: wrong StarIcon calculation in IOI mode

Standings: https://drive.google.com/file/d/1gojorOralJL1WHmpJsWcpzG-Knt9D-68/view?usp=sharing

Proof:

Tip: Darya Grekova must have a star in task №8

Introduced in: 26e8b6d

feat: Support updated event feed format

Support the updated event feed format, as defined here:
https://ccs-specs.icpc.io/master/contest_api#notification-format
