In a triangular workflow, each branch may have two distinct
points of interest: the @{upstream} that you normally pull
from, and the destination that you normally push to. There
isn't a shorthand for the latter, but it's useful to have.
For instance, you may want to know which commits you haven't
pushed yet:
git log @{push}..
Or as a more complicated example, imagine that you normally
pull changes from origin/master (which you set as your
@{upstream}), and push changes to your own personal fork
(e.g., as myfork/topic). You may push to your fork from
multiple machines, requiring you to integrate the changes
from the push destination, rather than upstream. With this
patch, you can just do:
git rebase @{push}
rather than typing out the full name.
The heavy lifting is all done by branch_get_push; here we
just wire it up to the "@{push}" syntax.

Now that most of the logic for our local get_upstream_branch

fold the remainder into interpret_upstream_mark.
Furthermore, what remains is generic to any branch-related
"@{foo}" we might add in the future, and there's enough
boilerplate that we'd like to reuse it. Let's parameterize

In a triangular workflow, the place you pull from and the
place you push to may be different. As we have
branch_get_upstream for the former, this patch adds
branch_get_push for the latter (and as the former implements
@{upstream}, so will this implement @{push} in a future
patch).
Note that the memory-handling for the return value bears
some explanation. Some code paths require allocating a new
string, and some let us return an existing string. We should
provide a consistent interface to the caller, so it knows
whether to free the result or not.
We could do so by xstrdup-ing any existing strings, and
having the caller always free. But that makes us
inconsistent with branch_get_upstream, so we would prefer to
simply take ownership of the resulting string. We do so by
storing it inside the "struct branch", just as we do with
the upstream refname (in that case we compute it when the
branch is created, but there's no reason not to just fill
it in lazily in this case).

After calling stat_tracking_info, callers often want to
print the name of the upstream branch (in addition to the
tracking count). To do this, they have to access
branch->merge->dst[0] themselves. This is not wrong, as the
return value from stat_tracking_info tells us whether we
have an upstream branch or not. But it is a bit leaky, as we
make an assumption about how it calculated the upstream
name.
Instead, let's add an out-parameter that lets the caller
know the upstream name we found.
As a bonus, we can get rid of the unusual tri-state return
from the function. We no longer need to use it to
differentiate between "no tracking config" and "tracking ref
does not exist" (since you can check the upstream_name for
that), so we can just use the usual 0/-1 convention for
success/error.

The error-diagnosis logic in branch_get_upstream was copied
straight from sha1_name.c in the previous commit. However,
because we check all error cases and upfront and then later
diagnose them, the logic is a bit tangled. In particular:
- if branch->merge[0] is NULL, we may end up dereferencing
it for an error message (in practice, it should never be
NULL, so this is probably not a triggerable bug).
- We may enter the code path because branch->merge[0]->dst
is NULL, but we then start our error diagnosis by
checking whether our local branch exists. But that is
only relevant to diagnosing missing merge config, not a
missing tracking ref; our diagnosis may hide the real
problem.
Instead, let's just use a sequence of "if" blocks to check
for each error type, diagnose it, and return NULL.

Usually, when 'git rebase' stops before completing the rebase, it is to
give the user an opportunity to edit a commit (e.g. with the 'edit'
command). In such cases, 'git rebase' leaves the sha1 of the commit being
rewritten in "$state_dir"/stopped-sha, and subsequent 'git rebase
--continue' will call the post-rewrite hook with this sha1 as <old-sha1>
argument to the post-rewrite hook.
The case of 'git rebase' stopping because of a failed 'exec' command is
different: it gives the opportunity to the user to examine or fix the
failure, but does not stop saying "here's a commit to edit, use
--continue when you're done". So, there's no reason to call the
post-rewrite hook for 'exec' commands. If the user did rewrite the
commit, it would be with 'git commit --amend' which already called the
post-rewrite hook.
Fix the behavior to leave no stopped-sha file in case of failed exec
command, and teach 'git rebase --continue' to skip record_in_rewritten if
no stopped-sha file is found.

The 'exec' command is sending the current commit to stopped-sha, which is
supposed to contain the original commit (before rebase). As a result, if

When the previous commit introduced the branch_get_upstream
helper, there was one call-site that could not be converted:
the one in sha1_name.c, which gives detailed error messages
for each possible failure.
Let's teach the helper to optionally report these specific
errors. This lets us convert another callsite, and means we
can use the helper in other locations that want to give the
same error messages.
The logic and error messages come straight from sha1_name.c,
with the exception that we start each error with a lowercase
letter, as is our usual style (note that a few tests need
updated as a result).

Before the previous commit, we had to make sure that

When remote.c loads its config, it records the
branch.*.pushremote for the current branch along with the
global remote.pushDefault value, and then binds them into a
single value: the default push for the current branch. We
then pass this value (which may be NULL) to remote_get_1
when looking up a remote for push.
This has a few downsides:
1. It's confusing. The early-binding of the "current
value" led to bugs like the one fixed by 98b406f
(remote: handle pushremote config in any order,
2014-02-24). And the fact that pushremotes fall back to
ordinary remotes is not explicit at all; it happens
because remote_get_1 cannot tell the difference between
"we are not asking for the push remote" and "there is
no push remote configured".
2. It throws away intermediate data. After read_config()
finishes, we have no idea what the value of
remote.pushDefault was, because the string has been
overwritten by the current branch's
branch.*.pushremote.
3. It doesn't record other data. We don't note the
branch.*.pushremote value for anything but the current
branch.
Let's make this more like the fetch-remote config. We'll
record the pushremote for each branch, and then explicitly
compute the correct remote for the current branch at the
time of reading.

When we create each branch struct, we fill in the
"remote_name" field from the config, and then fill in the
actual "remote" field (with a "struct remote") based on that
name. However, it turns out that nobody really cares about
the latter field. The only two sites that access it at all
are:
1. git-merge, which uses it to notice when the branch does
not have a remote defined. But we can easily replace this
with looking at remote_name instead.
2. remote.c itself, when setting up the @{upstream} merge
config. But we don't need to save the "remote" in the
"struct branch" for that; we can just look it up for
the duration of the operation.
So there is no need to have both fields; they are redundant
with each other (the struct remote contains the name, or you
can look up the struct from the name). It would be nice to
simplify this, especially as we are going to add matching
pushremote config in a future patch (and it would be nice to
keep them consistent).
So which one do we keep and which one do we get rid of?
If we had a lot of callers accessing the struct, it would be
more efficient to keep it (since you have to do a lookup to
go from the name to the struct, but not vice versa). But we
don't have a lot of callers; we have exactly one, so
efficiency doesn't matter. We can decide this based on
simplicity and readability.
And the meaning of the struct value is somewhat unclear. Is
it always the remote matching remote_name? If remote_name is
NULL (i.e., no per-branch config), does the struct fall back
to the "origin" remote, or is it also NULL? These questions
will get even more tricky with pushremotes, whose fallback
behavior is more complicated. So let's just store the name,
which pretty clearly represents the branch.*.remote config.
Any lookup or fallback behavior can then be implemented in
helper functions.

When we call branch_get() to lookup or create a "struct
branch", we make sure the "merge" field is filled in so that
callers can access it. But the conditions under which we do
so are a little confusing, and can lead to two funny
situations:
1. If there's no branch.*.remote config, we cannot provide
branch->merge (because it is really just an application
of branch.*.merge to our remote's refspecs). But
branch->merge_nr may be non-zero, leading callers to be
believe they can access branch->merge (e.g., in
branch_merge_matches and elsewhere).
It doesn't look like this can cause a segfault in
practice, as most code paths dealing with merge config
will bail early if there is no remote defined. But it's
a bit of a dangerous construct.
We can fix this by setting merge_nr to "0" explicitly
when we realize that we have no merge config. Note that
merge_nr also counts the "merge_name" fields (which we
_do_ have; that's how merge_nr got incremented), so we
will "lose" access to them, in the sense that we forget
how many we had. But no callers actually care; we use
merge_name only while iteratively reading the config,
and then convert it to the final "merge" form the first
time somebody calls branch_get().
2. We set up the "merge" field every time branch_get is
called, even if it has already been done. This leaks
memory.
It's not a big deal in practice, since most code paths
will access only one branch, or perhaps each branch
only one time. But if you want to be pathological, you
can leak arbitrary memory with:
yes @{upstream} | head -1000 | git rev-list --stdin
We can fix this by skipping setup when branch->merge is
already non-NULL.
In addition to those two fixes, this patch pushes the "do we
need to setup merge?" logic down into set_merge, where it is
a bit easier to follow.

The option parser for git-stash stuffs unknown flags into

Dropped refs/stash@{0} (e6cf6d80faf92bb7828f7b60c47fc61c03bd30a1)

annotate each command to reject a non-empty $FLAGS variable,
we can notice that "stash show" is the only command that
actually _wants_ arbitrary flags. So we switch the default
mode to reject unknown flags, and let stash_show() opt into
