When pushing a branch that didn't have an upstream yet, we use the command line
git push --set-upstream origin HEAD:branch-name
The HEAD: part of this is too unspecific; when checking out a different branch
while the push is still running, then git will set the upstream branch on the
newly checked out branch, not the branch that was being pushed. This might be
considered a bug in git; you might expect that it resolves HEAD at the beginning
of the operation, and uses the result at the end.
But we can easily work around this by explicitly supplying the real branch name
instead of HEAD.
In go 1.22, loop variables are redeclared with each iteration of the
loop, rather than simple updated on each iteration. This means that we
no longer need to manually redeclare variables when they're closed over
by a function.
By constructing an arg vector manually, we no longer need to quote arguments
Mandate that args must be passed when building a command
Now you need to provide an args array when building a command.
There are a handful of places where we need to deal with a string,
such as with user-defined custom commands, and for those we now require
that at the callsite they use str.ToArgv to do that. I don't want
to provide a method out of the box for it because I want to discourage its
use.
For some reason we were invoking a command through a shell when amending a
commit, and I don't believe we needed to do that as there was nothing user-
supplied about the command. So I've switched to using a regular command out-
side the shell there
