Bug 680688 – dev-lang/go-1.12.1 should only download files relevant to the host and target architecture

• Product: Gentoo Linux
• Status: RESOLVED CANTFIX

[Description Frank Krömmelbein 2019-03-17 10:10:40 UTC]

The ebuild for this new version fetches now 11 files with each about 50 MB in size. Required is normaly only one of them, thus about 500 MB will be unnecessarily downloaded. This probem is caused by this change:

I think we have to download all  of the bootstrap packages, unless there
is another way to do this I don't know about.

See bug #671394 and the following pull request:

The issue with the arch use flags amd64, x86, etc. which I removed is
that they are set to reflect the machine you are building *for*, not the
machine doing the building. This was breaking a crossdev environment.A

So, we either have big downloads or I start offering go-bin as a package
and using the upstream go binary releases.

[Comment 3 Tomáš Mózes 2019-03-18 05:09:30 UTC]

Can we add a comment to the ebuild (and a reference to this bug) so that one can lookup this information?

Personally, I'm fine with downloading even those 500MB, should not be a problem these days.

Thanks.

Thank you William for the detailed information. 
I can live with it, should i close the ticket or keep it open for some time?
