checkout & worktree: introduce checkout.defaultRemote
Introduce a checkout.defaultRemote setting which can be used to designate a remote to prefer (via checkout.defaultRemote=origin) when running e.g. "git checkout master" to mean origin/master, even though there's other remotes that have the "master" branch. I want this because it's very handy to use this workflow to checkout a repository and create a topic branch, then get back to a "master" as retrieved from upstream: ( cd /tmp && rm -rf tbdiff && git clone git@github.com:trast/tbdiff.git && cd tbdiff && git branch -m topic && git checkout master ) That will output: Branch 'master' set up to track remote branch 'master' from 'origin'. Switched to a new branch 'master' But as soon as a new remote is added (e.g. just to inspect something from someone else) the DWIMery goes away: ( cd /tmp && rm -rf tbdiff && git clone git@github.com:trast/tbdiff.git && cd tbdiff && git branch -m topic && git remote add avar git@github.com:avar/tbdiff.git && git fetch avar && git checkout master ) Will output (without the advice output added earlier in this series): error: pathspec 'master' did not match any file(s) known to git. The new checkout.defaultRemote config allows me to say that whenever that ambiguity comes up I'd like to prefer "origin", and it'll still work as though the only remote I had was "origin". Also adjust the advice.checkoutAmbiguousRemoteBranchName message to mention this new config setting to the user, the full output on my git.git is now (the last paragraph is new): $ ./git --exec-path=$PWD checkout master error: pathspec 'master' did not match any file(s) known to git. hint: 'master' matched more than one remote tracking branch. hint: We found 26 remotes with a reference that matched. So we fell back hint: on trying to resolve the argument as a path, but failed there too! hint: hint: If you meant to check out a remote tracking branch on, e.g. 'origin', hint: you can do so by fully qualifying the name with the --track option: hint: hint: git checkout --track origin/<name> hint: hint: If you'd like to always have checkouts of an ambiguous <name> prefer hint: one remote, e.g. the 'origin' remote, consider setting hint: checkout.defaultRemote=origin in your config. I considered splitting this into checkout.defaultRemote and worktree.defaultRemote, but it's probably less confusing to break our own rules that anything shared between config should live in core.* than have two config settings, and I couldn't come up with a short name under core.* that made sense (core.defaultRemoteForCheckout?). See also 70c9ac2f19 ("DWIM "git checkout frotz" to "git checkout -b frotz origin/frotz"", 2009-10-18) which introduced this DWIM feature to begin with, and 4e85333197 ("worktree: make add <path> <branch> dwim", 2017-11-26) which added it to git-worktree.
