I guess this is where git2_github.com.gcc-mirror.gcc.tar.gz download
comes from? It increased the size of my downloads-directory by >30% --
and I must have quite a bit of old junk in that directory already.
Is there no other solution to this than a 2.5G git copy (honest
question, I don't know gcc)?
We went down this road before and it wasn't great for users. There is
at
least a tarball for 6.1, we'd presumably need some patches on top of
that (~43 if we were to simply take what's in the gcc-6-branch between
6.1 and bd9a826, minus the "daily bumps").
Perhaps that was a little unclear - when I say "we went down this road
before" I'm agreeing with Jussi - we pointed to a git branch in a
previous release with the same resulting huge download for everyone,
something I think we should avoid if at all possible.
Maybe it's biggest but at least there is only one copy of it:
top 10 in my downloads (archives and then git clones).

No argument from me there - it does seem a little wasteful given that
there must be a huge overlap between those repos.
In other build systems, I've simply been able to reference a common
repository for the majority of the blobs. That isn't an option with
oe/bitbake (as far as I know).
It's possible we could add functionality along those lines to at least save
download time; disk usage would probably be unaffected though.
Nope. Disk usage goes down as well. With alternate objects, each
repo is only the size of what is unique to the repo.
We could also do shallow clones, but I'm also unsure of how well that
is supported.
I know Chris looked into adding this, I don't recall how far he got.
With the amount of series that are completely rebased and dynamic in
content, the trees do need to be separate per version. It becomes
completely un-bisectable and maintainable any other way.
Bisectability is function of how the branch is managed, not the repository -
surely? Perhaps I'm missing something.
Terminology perhaps? branch, repository .. whatever. They are all
the same.
Granularity of kernel commits. Over time with features like lttng,
aufs, preempt-rt, backports, etc, etc, It becomes impossible to
integrate new features and kernel updates without conflicts.
You end up with a tree riddled with merge commits, reverts and other
garbage that obscure the real changes.
I've lived that life, and its a not fun.
