SimView v1.4

With this release I have made UI code repo public (it was anyway accessible to all ) as I am not able to work much on it. Feel free to contribute any changes you would like . Backend (writer/http process) code is still private
Github: https://github.com/back-marker/sim-view-ui

ChangeLog:

• Enhancement:
  • Added support for SSL/TLS in both Writer/HTTP process. Both HTTP and WebSocket connection are secured. Check config.toml for more detail.
  • Writer process won't crash now when pit boundary cannot be constructed (due to missing KN5 files or any other reason). A warning will be logged to indicate this as pit entry/exit detection won't work in this case.
  • Writer/HTTP now take path (absolute/relative) to config.toml file as arguments.
  • Both processes will now search for config.toml in current working directory first then will look into config folder when no parameter given.
  • Added doc. for integrating automatic start/stop with ACSM (single server + multi server).

• Bug:
  • Fixed file path not printed correctly when relative path is set in game.path config.
  • Fixed failure in pitlane boundary creation when integer prefix is present in key name for pitlane mesh in surfaces.ini.
  • Fixed packets folder being created when AC server restarts (you can safely delete this folder if present).

Note: config.detail.toml file changed. Replace your config.toml file with new one

ChangeLog

• Enhancement:
  • The session list in results page will now only show session which are either live or has atleats one finished lap.
  • The standing, sector, stints tab in results page will now also show driver/team with no valid laps at the bottom of list.
  • Added y axis on right side as well for all graphs
  • Added car class selection to filter data shown in all graphs
  • Added 2 new graphs:
    • Gap to leader at the end of each lap
    • Pitstops time as stacked bar graph
  • Made all tabs in results page to load data lazily to avoid redundant HTTP request

• Bug:
  • Fixed driver flag in team livery preview
  • Fixed outliers not visible clearly in lap variation boxplot
  • Fixed sorting of values in boxplot tooltip

ChangeLog

• Enhancement:
  • SimViewTool executable now available can be used to generate required files from KN5 model file of tracks from you AC installation. You can now just upload the generared file to server instead of KN5 files. This will save disk space on your server as KN5 are huge in size. Refer manual on how to use SimViewTool.
  • Added consistency tab in results page. It shows drivers absolute error and consistency percent.
  • Added graphs tab in result page containing following graphs:
    • Lap time variation using boxplot
    • Lap time per lap
    • Pace per lap
    • Position per lap
    • All graphs support zoom and panning
• Bug:
  • Fixed straight line drawn between first and last point in telemetry graph.
  • Fixed issue with country flags. Check config.detail.toml on how to get new country codes.

Note: config.detail.toml file changed. Replace your config.toml file with new one

ChangeLog

• Bug:
  • Fixed issue with simview-1.2.sql script which caused it to create a new database (simview_1_2) on import. Only those who had fresh install through this script it would have created new database.

Lap telemetry is finally here!!

ChangeLog

• Feature:
  • Added new Analysis page for lap telemetry
    • Telemetry for single lap can be viewed and can be compared with one other lap
    • Currently shows Speed vs position, gear vs position and racing line on track map (same for comparison)
    • Single lap telemetry can be viewed from Best Lap page and Results page (standings tab for qualification/practice session and any lap in stints tab)
    • Comparing lap can be done from Bestlap page only by selecting two laps
    • Directly going to analysis page will show latest finished lap telemetry
    • Telemetry is saved for valid laps only and with min speed of 1km/hr. So it is skipped for in-lap, out-lap, stopping on track
    • Default AC Realtime interval set to 200ms (5Hz) for more accurate telemetry, and can be tuned further in config.toml
    • Track map now has sidelines for telemetry. New track maps will be automatically generated to replace old ones.
    • New config (ac.server.event.lap.telemetry.enable) to enable/disable telemetry

Note: config.detail.toml file changed. Replace your config.toml file with new one
Note: DB schema changed. If you were using older version, DB migration will be happen. Follow steps from the manual

Minor update with mostly bug fixes

ChangeLog

• Enhancement:
  • Added tyre change session feed event. Fast consecutive tyre change will be merge to one event.

• Bug:
  • Fixed pit entry and exit wrongly detected for U shaped pit lane ex. Daytona pit exit
  • Fixed same collision appearing twice in session feed
  • Fixed issue when driver continue to show as loading when it got disconnected while loading to server
  • Fixed to work with tracks which has no models.ini file. SimView will fallback to read all kn5 files present in track folder
  • Update config.detail.toml with ' for strings. This will allow \ for path related config in Windows
  • Fixed wrong error logged when kn5 file does not exists
  • Fixed folders in cache directories not created automatically in some cases ex. for pit boundary
  • Change MySQL host to 127.0.0.1 in config.detail.toml to work on Ubuntu
  • Fixed Final Lap not shown in countdown in time based race session
  • Fixed all session shown as [LIVE] in results page
  • Fixed event shown in live event page as greyed out for once after finishing

Note: config.detail.toml file changed. Replace your config.toml file with new one

Mostly bug fixes

ChangeLog:

• Enhancement:
  • Added sector times in practice/qualification result page standings

• Bug:
  • Fixed team leaderboad showing multiple entry for same team after driver swap

Team leaderboard shows multiple entry for a team after driver swap

Finally fix for issue when running with ACSM v2.

• Enhancement:
  • Live leaderboad will now work completely with AC servers running using Assetto Corsa Server Manager (ACSM) v2+ versions. Huge thanks to Callum Jones and team from ACSM for making this possible. Enable this feature with ac.server.udp.use.acsm.udp config when running AC servers from ACSM v2+ versions.

  • Fixed lights countdown timer in race session rendering in 2 lines in some cases.

Note: config.detail.toml file changed. Replace your config.toml file with new one

A lot of fundamental changes so marking it v1.0. Hoping it performs and look better now.

ChangeLog:

• Performance:
  • Moved live leaderboard API to Writer process. Single thread in Writer process will serve leaderboard API over configurable port (defaults to ac.server.udp.local.port). This port need to be opened to public (along with port for HTTP process) for Live Leaderboard to work now.
  • Changed live leaderboard API to WebSocket broadcast with binary data
  • Improved leaderboard serialisation performance to handle large leaderboard
  • Session feeds will now not be buffered at server side. It will now only send new feed generated since its last refresh
  • Writer process will now only use 1 connection to DB.
  • Leaderboard APIs now had start, current grip reducing extra request to HTTP process
  • Added new APIs to get multiple car/driver/teams in single request instead of doing multiple request to HTTP process. This APIs have per thread cache enabled with improved serialisation specific for live leaderboard
  • HTTP process will now use per thread DB connection instead of pool to avoid lock contention
  • Result stint tab will now not load all stints at once, but only when clicked on specific stint. For long duration events it used to request lot of data from HTTP process
  • Added compression for all HTTP static files
  • Added API to get multiple latest sessions in one requests
  • Made number of threads for HTTP process to be automatically decided, config (app.server.threads) is still there to override if needed.

• Enhancement:
  • Leaderboard now highlights personal best, session best last lap, sector times in practice/qualification/race leader-boards
  • Tyre used is now shown in live leaderboard, result and best-lap page
  • Added car track position indicator in last lap column in leaderboard (above last lap time)
  • Redesigned session feed UI
  • Added Live viewers count in leaderboard
  • Improved pit boundary computation for track which has very narrow pit entry and exit
  • Added SimView favicon icon for browser tabs
  • HTTP process will now honour If-Modified-Since header for static files request for browser to be able to cache files
  • Changed "Last Lap" to "Final Lap" in countdown
  • Show message when disconnected from leaderboard API and when high response time variation is observed in leaderboard API (indicating some issue with connection)
  • Config app.live.session.leaderboard.cache.size removed as leaderboard API is removed from HTTP process
  • Added config (ac.server.udp.realtime.update.interval.ms) for UDP real-time position interval set in AC server. (default 500ms)
  • Added config (writer.leaderboard.broadcast.interval.ms) to control leaderboard refresh interval. (default 2s). UI animations will sync with this configured interval.
  • Removed Date response headers of HTTP responses
  • Few back-end changes to enabled UDP packet logging to generate data for simulating sessions

• Bug:
  • Now elapsed session time will be used for countdown during time based sessions. This should bring SimView countdown close to AC in-game countdown.
  • Fixed extra pit exit feed shown when driver loads into the server
  • Fixed wrong last lap shown when same driver connects with different car
  • Fixed last stored combo not cleared in best-lap page when the combo is not valid any more

Note: DB schema changed. If you were using older version, DB migration will be happen. Follow steps from the manual
Note: config.detail.toml file changed. Replace your config.toml file with new one

Preview:

ChangeLog:

• Enhancement
  • Improved pit entry and exit detection logic, similar to Fair Racing App. No manual configuration required. Pit stop time in feed will now be from pit entry to pit exit (duration when speed limiter is active). This will required track's kn5 files to be accessible to SimView in track path
  • Added fallback to main content folder (first checks in server content folder) for files required by SimView
  • Removed position change, offtrack and rejoins feed event as it clutter feed
  • Show teleport to pit event in feed

• Bug:
  • Fixed drivers gaining 1 lap erroneously for a moment when crossing start-finish line. This will fix abrupt leaderboard position changes.
  • Fixed Writer crashing when server_cfg.ini cannot be parsed, and set limit for car list to 1000 chars
  • Fixed Writer crashing when empty GUID or extra ; found in entry_list.ini file
  • Fixed Writer crashing when track name contains '/' due to csp
  • Fixed password being shown in UI when chat enabled and ignore all chats starting with '/'
  • Fixed bug in v0.9 -> v0.10 migration scripts which caused session feed to not work
  • Fixed s1 s1 s1 showing in leaderboad sector columns for race session

Note: DB schema changed. If you were using older version, DB migration will be required. Follow steps from the manual

Small fix for some bugs

ChangeLog:

• Bug:
  • Remove extra long pit lanes in live track map generation. Will reduce false positive pit detections. New map will automatically replace old ones
  • Increase offtrack threshold detection, should detect only when whole car is offtrack
  • Fixed pit status when transition from a session to next session
  • Fixed pit and offtrack color not shown in leaderboard for even positions

ChangeLog

• Enhancement:
  • Improve live map generation to now use side lines from fast_lane.ai instead of ideal line. This will give more accurate track representation. For custom tracks which don't have side lines use this awesome app "AI Line Helper" from RD to add them.
  • Added offtrack and in pitlane status in live leaderboard and track map. It should detect teleport to pit as well.
  • New events in session feed:
    • Offtrack and subsequent rejoins from driver with track location
    • Pit entry and pit exit with total time spend in pit lane. Timer start when driver is "off the track" and entered the pit lane road and stops when driver is back "on track"
  • Best laps page will now remember your last combo viewed and will open it when you revisit.
  • Position gain and lose will now be shown in live leaderboard with green and red arrows.
  • Added hide option for whole car class in live track map.
  • Added tooltip for various leaderboad columns
  • Full name of driver or team for team event will be shown on hovering on particular car on live track map.
  • Session feed cache count increased to 50.

• Bug:
  • Fix issue where HTTP process crashes if it receives concurrent requests during its startup

Note: DB schema changed. If you were using older version, DB migration will be required. Follow steps from the manual

Finally an update after long time
ChangeLog

• Feature:
  • Added Session Feed UI in live track map tab.
  • Currently event shown in feed are:
    • Driver connect/disconnect
    • Driver swap in team event
    • Collisions (with corner names) and indicator on map
    • Session/stint best lap
    • Driver position change in leader board
    • Users chat messages (disabled by default in config)
    • 30 feed events are caches in HTTP process, on browser side no limit. Refreshing page will only show last 30 events.

• Enhancement:
  • Significant performance improvement in Writer process while data to DB. Should also fix issue when HTTP process seems behind in time.
  • Live map format updated to integrate with session feed. If you have old maps they will be automatically replaced with new ones.
  • Added handling for packet loss for session start and driver connect and disconnect packet.
  • Added option to get more entries in BestLaps page - by default 10 and max 50.
  • Moved some log to DEBUG to reduce HTTP process log file size.

• Bug:
  • Removed temp name feature for team event which caused issue with driver names automatically changing to team names
  • Fix speed in best lap page capped at 255KM/HR
  • Fix issue when other connected plugin connect to AC server sets very low real-time position and cause performance issue with Writer process. Writer process will now write data at fixed rate.
  • Fixed issue which allowed same cars to be selected multiple time in best laps page.
  • Drivers list will be shown in alphabetical order in Driver page

Note: config.detail.toml file changed. Replace your config.toml file with new one
Note: DB schema changed. If you were using older version, DB migration will be required. Follow steps from the manual

I have setup a server with SimView to iron out some bugs. It would be great if some of you guys can join the session and do some laps. Search SimView in CM/server browser. I will be monitoring it for any issue and will keep it running for a day or two. You can view SimView UI for this server from here.
