This is used by a special remote with sameas-uuid=
The remote's uuid is the sameas-uuid, but it needs to get
its RemoteConfig from the annex-config-uuid.
I found a way to avoid inheritance complicating anything outside of
Logs.Remote. It seems fine to require all inherited values to be
inherited and not set in the sameas remote's config. Since inherited
values will be used for stuff like encryption and perhaps chunking, which
control the actual content stored on the remote, it seems likely that
there will not be any reason to need them to vary between two remotes
that access the same underlying data store.
The newer version of containers is free; the minimum ghc version is
bundled with a newer version than that.
Initremote sets that, so after both initremote and enableremote,
the git config will be set.
Any remote that does not use Annex.SpecialRemote won't set
annex-config-uuid. But that's only Remote.Git, which doesn't use
RemoteConfig anyway.
initremote --sameas=remotename sets sameas-name and sameas-uuid
Using sameas-name rather than name prevents old git-annex initremote
from enabling a sameas remote by name, since it would not handle it
correctly.
Work around git cat-file --batch's odd stripping of carriage return from
the end of the line (some windows infection), avoiding crashing when the
repo contains a filename ending in a carriage return.
When dropping an unlocked file, preserve its mtime, which avoids git status
unncessarily running the clean filter on the file.
If the index file has close to the same mtime as a work tree file, git will
not trust the index to be up-to-date, and re-runs the clean filter
unncessarily. Preserving the mtime when depopulating a pointer file avoids
git status doing a little (or maybe a lot) of unncessary work.
There are other places that the mtime could be preserved, including other
places where pointer files are written perhaps, but also
populatePointerFile. But, I don't know of cases where those lead to git
status doing unncessary work, so I just fixed the one I'm aware of for now.
