Blocking UI updates when updating

[ewindso]

Thanks for making this! One thing I notice is that when I check for an update after come back from the background, the UI seems blocked. This doesn't happen when it's initially updating using the same method (runUpdateProcess).

However when coming back from the background, it also checks for an update -- and if there is one, the UI is blocked from interaction. (ScrollViews scroll, but taps do not work, cannot do anything else.) Also, even the progress from useHotUpdaterStore seems not to update.

This is on iOS. I haven't yet gotten to Android, just wanting to get past this. One potential workaround I see is showing a full-screen splash screen, with a spinner (loading progress won't work since it can't update UI...)

Any help on fixing it would be appreciated! Thank you.

Could you provide a reproduction code?

I noticed something similar in ios, there is no problem when I forceupdate. fallbackComponent is shown and reload works successfully, but when forceupdate is false. when the application is first opened, the ui is blocked during the update time, fallbackComponent is not shown and navigation operations do not occur because the ui is blocked.

version 0.7.0

@gronxb @mstfmedeni I think the issue is with the native updateBundle method, how it uses dispatch_semaphore_wait. According to ChatGPT, it blocks the thread it's called on. I forked and am going to try a dispatch_async around it to see if that helps, when calling it from the RN method. If so, will post a PR here.

@gronxb I would provide a JS example but the way our project does updates (or used to do them in CodePush) is a little complex.

Ok @gronxb @mstfmedeni this seems to fix it:

@gronxb @mstfmedeni just fyi sending events was happening too quick for me on iOS, UI thread was getting clogged... I added this in, seems to fix:

I got the same issue with the latest version (v0.12.0) on Android.
When I release a new hot update version -> open the app -> it checks checking new version and gets block UI
