Instead of duplicating the permissions on the temp file, the permissions
are duplicated on the output file directly. If the output file exists as
read-only, it is made writeable first.
There are some environments which don't allow the mv to work if the file
itself is read-only.
Instead of doing work to find the default branch just to be able to
set up the repository before doing a fetch, do a "git clone" and let
git handle it.
Use -c core.sharedrepository=0600 to get the same result as
--shared=0600 passed to init.
Use --separate-git-dir to get the git directory in $YADM_REPO. Use a
temporary dir as work tree and remove it right after the clone is
done.
When the clone is done, iterate over all missing files in $YADM_WORK
and perform a checkout. If local files exists that differ compared
with the cloned ones the local files are left intact and the user is
instructed to deal with the conflicts.
Don't rely on internals from the git completion. Instead set up the
environment and then simply call _git and let it do the completion as
it see fit.
See #292.
This makes it possible to run e.g. "yadm -Y foo introspect repo
2>/dev/null" and get an empty output instead of getting the error
message about foo not being fully qualified.
Start with doing "submodule absorbgitdirs" as otherwise "submodule
deinit" will fail if a module has been cloned first and later added as
a submodule (as it will then contain the .git dir instead of it being
under the superprojects .git dir).
Then try to deinit the submodules before moving the repo and abort the
upgrade if it fails for any submodule. Then do the move and finally
initialize the submodules that were initialized before the upgrade.
See #285
Also symlink instead of copy in that case, so that changes locally can
be reflected in the testhost directly, and print the used version in a
more readable format.
