Update applications

[jm42]

Now is not possible to install an application that is already installed, even if the last version is newer that the installed version. For a future where the store can update applications, the first step would be showing the last application version from data.json.

Then to show the installed version. The App object has the complete manifest with the version.

It also has a checkForUpdate() method.

Seems like checkForUpdate() might be an Firefox OS only feature.

Firefox OS on the phone polls once per day for changes to an app. To do this, it polls the URL of the mini-manifest, then polls the URL in the package_path field in the mini-manifest. This is done using the checkForUpdate() method on the App object. When the ETag header changes, it knows the app has been updated. Then it checks if the zip file has changed.

Unfortunately I don't know how to update an app without losing the user data. uninstall-> download new version -> install

I think for this to happen, the backend needs to be revamped completely, moving away from the OmniSD format to having mini manifests and application zips: https://developer.mozilla.org/en-US/docs/Archive/Marketplace/API/DOMApplicationsRegistry/install

can we use it to install a certified app?

I think it should be able to, you could try. I guess this is the same mechanism that the KaiStore uses to install apps behind the scenes.

I don't think we need to completely move away from the OmniSD format. OmniSD zip already have application.zip and manifest as long as I remember.

you could try if import () works without OmniSD then you could use both.

At lest the store should show last version (and, if installed, the current version.)
