836232 - [stub installer] Use caching for the downloaded installer

Status: RESOLVED WONTFIX

(Firefox :: Installer, enhancement)

Description

[Henrik Skupin [:whimboo][⌚️UTC+1]]

If you install Firefox through the stub installer and there is another running instance of Firefox (e.g. Nightly, Aurora) active, the installation will fail with the default settings. When you run the stub installer again it will re-download the whole package.

Don't we have a cache we could make use of? Or is that not implemented yet?

So in the given case above Firefox has already been installed. So with my steps I triggered a completely new installation. So putting the downloaded file into the cache, would help to speed up installation time and lower the amount of data to download. Mostly people will be affected here, for whom the installation process failed.

Sounds like what you've described is the "resume support" enhancement in bug 798005.

Actually change that - this situation is a bit different as it's a cross-over in installs.

Right. Now sure what rob thinks about it but if we want to make use of a cache your resume bug would most likely depend on it.

Why did the install fail? The install typically succeeds even when Firefox is in use though we don't launch the new version as stated in the messagebox.

The download performed by the stub does not use any existing profiles, caches, etc. and what it does use it cleans up at the end intentionally... it would be bad form to leave things like that around along with the goal is to successfully install the first time (which it does typically though there have been server side issues recently) so this would end up being for an edgecase.

The installation hasn't failed for this case for quite some time.

Per comment #6 we don't and intentionally don't keep these files around. Also, all stub installers download the latest build offered by bouncer for the channel associated with the stub so a cache as described could easily be problematic.
