checkout tests: index should be clean after dwim checkout
Assert that whenever there's a DWIM checkout that the index should be
clean afterwards, in addition to the correct branch being checked-out.
The way the DWIM checkout code in checkout.[ch] works is by looping
over all remotes, and for each remote trying to find if a given
reference name only exists on that remote, or if it exists anywhere
else.
This is done by starting out with a `unique = 1` tracking variable in
a struct shared by the entire loop, which will get set to `0` if the
data reference is not unique.
Thus if we find a match we know the dst_oid member of
tracking_name_data must be correct, since it's associated with the
only reference on the only remote that could have matched our query.
But if there was ever a mismatch there for some reason we might end up
with the correct branch checked out, but at the wrong oid, which would
show whatever the difference between the two staged in the
index (checkout branch A, stage changes from the state of branch B).
So let's amend the tests (mostly added in) 399e4a1c56 ("t2024: Add
tests verifying current DWIM behavior of 'git checkout <branch>'",
2013-04-21) to always assert that "status" is clean after we run
"checkout", that's being done with "-uno" because there's going to be
some untracked files related to the test itself which we don't care
about.
In all these tests (DWIM or otherwise) we start with a clean index, so
these tests are asserting that that's still the case after the
"checkout", failed or otherwise.
Then if we ever run into this sort of regression, either in the
existing code or with a new feature, we'll know.

checkout: add advice for ambiguous "checkout <branch>"
As the "checkout" documentation describes:
If <branch> is not found but there does exist a tracking branch in
exactly one remote (call it <remote>) with a matching name, treat
as equivalent to [...] <remote>/<branch.
This is a really useful feature. The problem is that when you add
another remote (e.g. a fork), git won't find a unique branch name
anymore, and will instead print this unhelpful message:
$ git checkout master
error: pathspec 'master' did not match any file(s) known to git
Now it will, on my git.git checkout, print:
$ ./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>
Note that the "error: pathspec[...]" message is still printed. This is
because whatever else checkout may have tried earlier, its final
fallback is to try to resolve the argument as a path. E.g. in this
case:
$ ./git --exec-path=$PWD checkout master pu
error: pathspec 'master' did not match any file(s) known to git.
error: pathspec 'pu' did not match any file(s) known to git.
There we don't print the "hint:" implicitly due to earlier logic
around the DWIM fallback. That fallback is only used if it looks like
we have one argument that might be a branch.
I can't think of an intrinsic reason for why we couldn't in some
future change skip printing the "error: pathspec[...]" error. However,
to do so we'd need to pass something down to checkout_paths() to make
it suppress printing an error on its own, and for us to be confident
that we're not silencing cases where those errors are meaningful.
I don't think that's worth it since determining whether that's the
case could easily change due to future changes in the checkout logic.

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.

checkout tests: index should be clean after dwim checkout
Assert that whenever there's a DWIM checkout that the index should be
clean afterwards, in addition to the correct branch being checked-out.
The way the DWIM checkout code in checkout.[ch] works is by looping
over all remotes, and for each remote trying to find if a given
reference name only exists on that remote, or if it exists anywhere
else.
This is done by starting out with a `unique = 1` tracking variable in
a struct shared by the entire loop, which will get set to `0` if the
data reference is not unique.
Thus if we find a match we know the dst_oid member of
tracking_name_data must be correct, since it's associated with the
only reference on the only remote that could have matched our query.
But if there was ever a mismatch there for some reason we might end up
with the correct branch checked out, but at the wrong oid, which would
show whatever the difference between the two staged in the
index (checkout branch A, stage changes from the state of branch B).
So let's amend the tests (mostly added in) 399e4a1c56 ("t2024: Add
tests verifying current DWIM behavior of 'git checkout <branch>'",
2013-04-21) to always assert that "status" is clean after we run
"checkout", that's being done with "-uno" because there's going to be
some untracked files related to the test itself which we don't care
about.
In all these tests (DWIM or otherwise) we start with a clean index, so
these tests are asserting that that's still the case after the
"checkout", failed or otherwise.
Then if we ever run into this sort of regression, either in the
existing code or with a new feature, we'll know.

checkout tests: index should be clean after dwim checkout
Assert that whenever there's a DWIM checkout that the index should be
clean afterwards, in addition to the correct branch being checked-out.
The way the DWIM checkout code in checkout.[ch] works is by looping
over all remotes, and for each remote trying to find if a given
reference name only exists on that remote, or if it exists anywhere
else.
This is done by starting out with a `unique = 1` tracking variable in
a struct shared by the entire loop, which will get set to `0` if the
data reference is not unique.
Thus if we find a match we know the dst_oid member of
tracking_name_data must be correct, since it's associated with the
only reference on the only remote that could have matched our query.
But if there was ever a mismatch there for some reason we might end up
with the correct branch checked out, but at the wrong oid, which would
show whatever the difference between the two staged in the
index (checkout branch A, stage changes from the state of branch B).
So let's amend the tests (mostly added in) 399e4a1c56 ("t2024: Add
tests verifying current DWIM behavior of 'git checkout <branch>'",
2013-04-21) to always assert that "status" is clean after we run
"checkout", that's being done with "-uno" because there's going to be
some untracked files related to the test itself which we don't care
about.
In all these tests (DWIM or otherwise) we start with a clean index, so
these tests are asserting that that's still the case after the
"checkout", failed or otherwise.
Then if we ever run into this sort of regression, either in the
existing code or with a new feature, we'll know.

checkout: Use remote refspecs when DWIMming tracking branches
The DWIM mode of checkout allows you to run "git checkout foo" when there
is no existing local ref or path called "foo", and there is exactly _one_
remote with a remote-tracking branch called "foo". Git will automatically
create a new local branch called "foo" using the remote-tracking "foo" as
its starting point and configured upstream.
For example, consider the following unconventional (but perfectly valid)
remote setup:
[remote "origin"]
fetch = refs/heads/*:refs/remotes/origin/*
[remote "frotz"]
fetch = refs/heads/*:refs/remotes/frotz/nitfol/*
Case 1: Assume both "origin" and "frotz" have remote-tracking branches called
"foo", at "refs/remotes/origin/foo" and "refs/remotes/frotz/nitfol/foo"
respectively. In this case "git checkout foo" should fail, because there is
more than one remote with a "foo" branch.
Case 2: Assume only "frotz" have a remote-tracking branch called "foo". In
this case "git checkout foo" should succeed, and create a local branch "foo"
from "refs/remotes/frotz/nitfol/foo", using remote branch "foo" from "frotz"
as its upstream.
The current code hardcodes the assumption that all remote-tracking branches
must match the "refs/remotes/$remote/*" pattern (which is true for remotes
with "conventional" refspecs, but not true for the "frotz" remote above).
When running "git checkout foo", the current code looks for exactly one ref
matching "refs/remotes/*/foo", hence in the above example, it fails to find
"refs/remotes/frotz/nitfol/foo", which causes it to fail both case #1 and #2.
The better way to handle the above example is to actually study the fetch
refspecs to deduce the candidate remote-tracking branches for "foo"; i.e.
assume "foo" is a remote branch being fetched, and then map "refs/heads/foo"
through the refspecs in order to get the corresponding remote-tracking
branches "refs/remotes/origin/foo" and "refs/remotes/frotz/nitfol/foo".
Finally we check which of these happens to exist in the local repo, and
if there is exactly one, we have an unambiguous match for "git checkout foo",
and may proceed.
This fixes most of the failing tests introduced in the previous patch.

checkout tests: index should be clean after dwim checkout
Assert that whenever there's a DWIM checkout that the index should be
clean afterwards, in addition to the correct branch being checked-out.
The way the DWIM checkout code in checkout.[ch] works is by looping
over all remotes, and for each remote trying to find if a given
reference name only exists on that remote, or if it exists anywhere
else.
This is done by starting out with a `unique = 1` tracking variable in
a struct shared by the entire loop, which will get set to `0` if the
data reference is not unique.
Thus if we find a match we know the dst_oid member of
tracking_name_data must be correct, since it's associated with the
only reference on the only remote that could have matched our query.
But if there was ever a mismatch there for some reason we might end up
with the correct branch checked out, but at the wrong oid, which would
show whatever the difference between the two staged in the
index (checkout branch A, stage changes from the state of branch B).
So let's amend the tests (mostly added in) 399e4a1c56 ("t2024: Add
tests verifying current DWIM behavior of 'git checkout <branch>'",
2013-04-21) to always assert that "status" is clean after we run

branch.c: Validate tracking branches with refspecs instead of refs/remotes/*
The current code for validating tracking branches (e.g. the argument to
the -t/--track option) hardcodes refs/heads/* and refs/remotes/* as the
potential locations for tracking branches. This works with the refspecs
created by "git clone" or "git remote add", but is suboptimal in other
cases:
- If "refs/remotes/foo/bar" exists without any association to a remote
(i.e. there is no remote named "foo", or no remote with a refspec
that matches "refs/remotes/foo/bar"), then it is impossible to set up
a valid upstream config that tracks it. Currently, the code defaults
to using "refs/remotes/foo/bar" from repo "." as the upstream, which
works, but is probably not what the user had in mind when running
"git branch baz --track foo/bar".
- If the user has tweaked the fetch refspec for a remote to put its
remote-tracking branches outside of refs/remotes/*, e.g. by running
git config remote.foo.fetch "+refs/heads/*:refs/foo_stuff/*"
then the current code will refuse to use its remote-tracking branches
as --track arguments, since they do not match refs/remotes/*.
This patch removes the "refs/remotes/*" requirement for upstream branches,
and replaces it with explicit checking of the refspecs for each remote to
determine whether a given --track argument is a valid remote-tracking
branch. This solves both of the above problems, since the matching refspec
guarantees that there is a both a remote name and a remote branch name
that can be used for the upstream config.
However, this means that refs located within refs/remotes/* without a
corresponding remote/refspec will no longer be usable as upstreams.
The few existing tests which depended on this behavioral quirk has
already been fixed in the preceding patches.
This patch fixes the last remaining test failure in t2024-checkout-dwim.

checkout: report upstream correctly even with loosely defined branch.*.merge
When checking out a branch that is set to build on top of another
branch (often, a remote-tracking branch), "git checkout" reports how
your work relates to the other branch, e.g.
Your branch is behind 'origin/master', and can be fast-forwarded.
Back when this feature was introduced, this was only done for
branches that build on remote-tracking branches, but 5e6e2b48 (Make
local branches behave like remote branches when --tracked,
2009-04-01) added support to give the same report for branches that
build on other local branches (i.e. branches whose branch.*.remote
variables are set to '.'). Unlike the support for the branches
building on remote-tracking branches, however, this did not take
into account the fact that branch.*.merge configuration is allowed
to record a shortened branch name.
When branch.*.merge is set to 'master' (not 'refs/heads/master'),
i.e. "my branch builds on the local 'master' branch", this caused
"git checkout" to report:
Your branch is based on 'master', but the upstream is gone.
The upstream is our repository and is definitely not gone, so this
output is nonsense.
The fix is fairly obvious; just like the branch name is DWIMed when
"git pull" merges from the 'master' branch without complaint on such
a branch, the name of the branch the current branch builds upon
needs to be DWIMed the same way.

these tests are asserting that that's still the case after the
"checkout", failed or otherwise.
Then if we ever run into this sort of regression, either in the
existing code or with a new feature, we'll know.

checkout: report upstream correctly even with loosely defined branch.*.merge
When checking out a branch that is set to build on top of another
branch (often, a remote-tracking branch), "git checkout" reports how
your work relates to the other branch, e.g.
Your branch is behind 'origin/master', and can be fast-forwarded.
Back when this feature was introduced, this was only done for
branches that build on remote-tracking branches, but 5e6e2b48 (Make
local branches behave like remote branches when --tracked,
2009-04-01) added support to give the same report for branches that
build on other local branches (i.e. branches whose branch.*.remote
variables are set to '.'). Unlike the support for the branches
building on remote-tracking branches, however, this did not take
into account the fact that branch.*.merge configuration is allowed
to record a shortened branch name.
When branch.*.merge is set to 'master' (not 'refs/heads/master'),
i.e. "my branch builds on the local 'master' branch", this caused
"git checkout" to report:
Your branch is based on 'master', but the upstream is gone.
The upstream is our repository and is definitely not gone, so this
output is nonsense.
The fix is fairly obvious; just like the branch name is DWIMed when
"git pull" merges from the 'master' branch without complaint on such
a branch, the name of the branch the current branch builds upon
needs to be DWIMed the same way.

checkout tests: index should be clean after dwim checkout
Assert that whenever there's a DWIM checkout that the index should be
clean afterwards, in addition to the correct branch being checked-out.
The way the DWIM checkout code in checkout.[ch] works is by looping
over all remotes, and for each remote trying to find if a given
reference name only exists on that remote, or if it exists anywhere
else.
This is done by starting out with a `unique = 1` tracking variable in
a struct shared by the entire loop, which will get set to `0` if the
data reference is not unique.
Thus if we find a match we know the dst_oid member of
tracking_name_data must be correct, since it's associated with the
only reference on the only remote that could have matched our query.
But if there was ever a mismatch there for some reason we might end up
with the correct branch checked out, but at the wrong oid, which would
show whatever the difference between the two staged in the
index (checkout branch A, stage changes from the state of branch B).
So let's amend the tests (mostly added in) 399e4a1c56 ("t2024: Add
tests verifying current DWIM behavior of 'git checkout <branch>'",
2013-04-21) to always assert that "status" is clean after we run
"checkout", that's being done with "-uno" because there's going to be
some untracked files related to the test itself which we don't care
about.
In all these tests (DWIM or otherwise) we start with a clean index, so
these tests are asserting that that's still the case after the
"checkout", failed or otherwise.
Then if we ever run into this sort of regression, either in the
existing code or with a new feature, we'll know.
