832684 - Restarting a failed install doesn't get the new manifest if it changed

Status: RESOLVED WONTFIX

(Core Graveyard :: DOM: Apps, defect)

Description

[Julien Wajsberg [:julienw]]

STR:
* have a hosted+appcache webapp with a wrong path for the appcache manifest in the webapp manifest
* install this app
=> it should fail
* fix the bad path in the webapp manifest
* restart the download from the app icon in the homescreen

Expected:
* it should now work

Actual:
* it still fails

Workaround:
* delete the app and install it again.

Should not block but I think this should eventually be fixed.

If you don't check for update, there's no way we can guess the appcache_path has changed in the manifest. Or I am missing something there?

This is more a proposition that an affirmation here, if you think this is a bad idea let's just close it wontfix.

What I propose here is that if an app's installState is "pending", then when restarting a download, we should download the manifest again.

I didn't tried with packaged apps, but the case is quite similar if the package_path is wrong. 

I don't know either for update cases.

I don't like that because there is no way to distinguish between a bad manifest and a server side issue. So it's very likely we will refetuch the manifest for no better result.
