[Refactor] Offline detection #1727

arielj · 2022-08-14T23:50:37Z

This PR adds the offline/online detection + ping + event handling

Done:

check connectivity at startup
use the window offline and online events to detect when a network connection is active/inactive
show a message to the use that we are either offline or retrying the internet check
ping some websites we use, using axios with HEAD method to check internet connectivity
retry after 5 seconds if all pings fail
replaced the calls to isOnline with the new isOnline from online_monitor.ts
backend emits an event that can be listened to to do something when connection is back (check electron/anticheat/utils.ts:11)
added the Connection prefix for the logger
react app has a connectivity state that we can use anywhere if needed to show connectivity-related message (or to disable actions like opening a website or logging in for example)
handle heroic initialization when no internet connection (and initialize properly when it goes online), we can listen to the online event once to do things at boot waiting for the connection to be available and only once
more info to the user (show the list of sites we are pinging during retries)
i18n
increase the time between retries after it fails

TODO after merging this:

detect when an external request failed and do a ping to check if the request simply failed or we are actually offline and set the correct status to start pinging

I added a checkConnectivity function exported in online_monitor.ts that could be called after doing something that relies on an external request and we detect the connection failed. I didn't add this in this PR since I don't really know all the places where this can happen. I think it's better to start adding this calls to checkConnectivity when things fail as we find them.

TODO (I'll leave these things for the future maybe, this is more like polishing):

add an option to dismiss the retry message?
add an option retry on demand?
show a warning if offline and a game does not support offline mode
disable download/update features when offline?
disable verify and repair when offline?
disable other actions that require internet when offline?

For me the idea looks promising. Code vice also pretty good.
Love this eventlistener:

  ipcMain.once('online', async () => {
    try {
      const { data } = await axios.default.get(
        'https://raw.githubusercontent.com/Starz0r/AreWeAntiCheatYet/HEAD/games.json'
      )
      writeFileSync(heroicAnticheatDataPath, JSON.stringify(data, null, 2))
      logInfo(`AreWeAntiCheatYet data downloaded`, LogPrefix.Backend)
    } catch (error) {
      logWarning(
        `Failed download of AreWeAntiCheatYet data: ${error}`,
        LogPrefix.Backend
      )
    }
  })

    }
  })

I'm planning to add a helper method like if we are online right now, do this, else wait until we are online, because now that is not triggered the callback if the event was fired before adding the listener, but should be a simple thing to do

Tested and it works. I wonder if we really need the retry. It is going on forever. It is somehow really annoying to see the timer all the time. We should be silent till the user trys something what needs internet.

Is it also possible to log less informations. Lets say just a message that we retry in 25 secs. Don't log every secs count?

Should this be maybe also merged against beta, so we can test this more in a beta release?

Overall really good stuff and nice code :).

Tested and it works. I wonder if we really need the retry. It is going on forever. It is somehow really annoying to see the timer all the time. We should be silent till the user trys something what needs internet.

I was planning a dismiss / x button to remove the div until the next time it goes offline. I didn't want to add that just yet to not add more things to this PR though (I want a few more things after getting this merged).

Is it also possible to log less informations. Lets say just a message that we retry in 25 secs. Don't log every secs count?

sure!

I'll change it to beta today, I forgot about that (I started this against main and forgot about it hahah)

arielj · 2022-09-17T02:43:44Z

@Nocccer moved this to be against beta, removed the seconds retry log, I'll leave the dismiss (and other features) for after this is merged

Nocccer

I found a small frontend ui problem, where the showed seconds jump between random numbers and not counting down as expected. Here is a video. I start heroic without internet and after a time i connect internet again. At this moment numbers jumping

This is cool. Definitely an important feature covering the case where connection drops out or the user starts the app offline but then goes online after launch without having to restart the app. I tested on windows 11, and it is working for me. Left some comments.

@Nocccer can you check if the issue is still present? I was not sure how to reproduce it so I just added a check to make sure any previous timeout is stopped after starting a new timeout just in case

Nocccer · 2022-10-03T16:07:38Z

I still have the number bug. Here is a log. I just added a console.log(seconds) in the retry function.

You can see that at seconds 11 i got the connection back and the retry seconds get up to 20.

Also a big problem is that if i start heroic without internet, it always start with retry. Should it not be just showing offline and should retry if the connection is back again?

…key change

arielj · 2022-10-03T22:20:25Z

@Nocccer thanks, I think I fixed the counter issue now, I was able to reproduce it and now it should revert back to 5 seconds after an online or offline event properly.

I also changed it to not start retrying if it's currently offline.

Nocccer

Works like a charm now :). Really good stuff
