920481 - [app manager] if the app is running when we click "update", the app is not killed

Status: VERIFIED FIXED

Is stopping and starting the app after install what we want here?  Or is the some kind of faster "refresh" we can offer to reload the app?

Yes.

[Alexandre Poirot [:ochameau]]

That's a poor UX. Seeing the app close/open doesn't look very important/usefull and will take sigificant amount of time due to the animation. Also closing/opening apps are complex operations where we still don't really know exactly when the app is done closing/opening. So I'm expecting such behavior would be harder to implement right.
I think we should try to do what simulator was doing, i.e. refreshing the frame.
The simulator was having the bad practice to call gaia codebase, it was calling this method:
  https://mxr.mozilla.org/gaia/source/apps/system/js/window.js#143
But we can simply fetch the frame from the actor and call frame.reload(true).

Attachment: Reload app frame after update

Alex, I've attempted your plan of calling frame.reload(true), but it doesn't seem to work too well for me.  The page flashes briefly while reloading, but it reappears with the old content.  Is there some additional cache clearing I need to do?

I am able to see the new content by stopping and starting the app after install.

Comment 6

[Alexandre Poirot [:ochameau]]

I've been looking at this and for me it seems to work only once, that's a really weird behavior.
Luca identified that we are missing a fix we had in the old simulator app actor, where we were flushing the jar:
http://mxr.mozilla.org/mozilla-central/source/dom/apps/src/Webapps.jsm#1408

I tried to also fire this flush notification, but it doesn't fix this...

I'll look into this.

Here is the UI patch, that just call the existing reload method of BrowserTabActor that does a window.location.reload()

Attachment: Ensure flushing jar cache when updating an app r=paul

Here is a device fix, that's an uplift from the old simulator codebase.
We need to flush the jar cache when updating the app zip package.
But it is a bit more complex on device, with apps running OOP.
We have to flush the cache in the app process itself.

This whole function could be moved to app-actor-front.js or a similar file.  I was liking the trend of separating UI logic from the calls to the debugger API that we got from having things in app-actor-front.js, so it would be nice to continue that.

That could return a promise you can use to log "App reloaded".

Hopefully "soon" we can refactor this file a bit, as it is quite a mess...

Looks good overall!  It's quite a nice UX to see it reload in place!  :D

Is there any harm to running this on device?  I guess it will just be ignored safely...?

Yes, especially since we give the precise application jar path. The jar channel will only prune cache for this particular jar.

I had to add this to prevent test exceptions on desktop.

[Approval Request Comment]
Bug caused by (feature/regressing bug #): new feature (app manager)
User impact if declined: repushing an app via the app manager doesn't update the app, the user has to kill the app manually

Alex, can we uplift that to the Simulator in the meantime?

Comment 23

[Garrett Robinson [:grobinson]]

I have this problem with the 1.2 simulator and it is quite annoying. Please uplift ASAP?

Comment 24

[Alexandre Poirot [:ochameau]]

We no longer build a custom b2g runtime, nor have a custom copy of webapps actor.
So we can't really uplift it as-is on the simulator without uplifting this patch on m-c.

Otherwise, we should ensure that approval-mozilla-b2g26 is still tracked...

Can you use version 1.3 in the meantime?

Go ahead & land this - this is critical for dev tools experience with apps.

This is awesome! Just downloaded the latest 1.3 simulator and clicking "Update" worked perfectly. Thanks everyone! (Now I can continue working on adding OTR support to https://github.com/waalt/loqui with minimal frustration)
