Jeff King 3a429d0af3 remote.c: report specific errors from branch_get_upstream
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).

Max Kirillov ad2f7255b3 git-show: fix 'git show -s' to not add extra terminator after merge commit
When git show -s is called for merge commit it prints extra newline
after any merge commit. This differs from output for commits with one
parent. Fix it by more thorough checking that diff output is disabled.

The code in question exists since commit 3969cf7db1. The additional
newline is really needed for cases when patch is requested, test
t4013-diff-various.sh contains cases which can demonstrate behavior when
the condition is restricted further.

Tests:

Added merge commit to 'set up a bit of history' case in t7007-show.sh to
cover the fix.

Existing tests are updated to demonstrate the new behaviour.  Earlier,
the tests that used "git show -s --pretty=format:%s", even though
"--pretty=format:%s" calls for item separator semantics and does not ask
for the terminating newline after the last item, expected the output to
end with such a newline.  They were relying on the buggy behaviour.  Use
of "--format=%s", which is equivalent to "--pretty=tformat:%s" that asks
for a terminating newline after each item, is a more realistic way to
use the command.

In the test 'merge log messages' the expected data is changed, because
it was explicitly listing the extra newline. Also the msg.nologff and
msg.nolognoff expected files are replaced by one msg.nolog, because they
were diffing because of the bug, and now there should be no difference.

Jeff King 9892d5d454 interpret_branch_name: find all possible @-marks
When we parse a string like "foo@{upstream}", we look for
the first "@"-sign, and check to see if it is an upstream
mark. However, since branch names can contain an @, we may
also see "@foo@{upstream}". In this case, we check only the
first @, and ignore the second. As a result, we do not find
the upstream.

We can solve this by iterating through all @-marks in the
string, and seeing if any is a legitimate upstream or
empty-at mark.

Another strategy would be to parse from the right-hand side
of the string. However, that does not work for the
"empty_at" case, which allows "@@{upstream}". We need to
find the left-most one in this case (and we then recurse as
"HEAD@{upstream}").

Jeff King 3f6eb30f1d interpret_branch_name: avoid @{upstream} past colon
get_sha1() cannot currently parse a valid object name like
"HEAD:@{upstream}" (assuming that such an oddly named file
exists in the HEAD commit). It takes two passes to parse the
string:

  1. It first considers the whole thing as a ref, which
     results in looking for the upstream of "HEAD:".

  2. It finds the colon, parses "HEAD" as a tree-ish, and then
     finds the path "@{upstream}" in the tree.

For a path that looks like a normal reflog (e.g.,
"HEAD:@{yesterday}"), the first pass is a no-op. We try to
dwim_ref("HEAD:"), that returns zero refs, and we proceed
with colon-parsing.

For "HEAD:@{upstream}", though, the first pass ends up in
interpret_upstream_mark, which tries to find the branch
"HEAD:". When it sees that the branch does not exist, it
actually dies rather than returning an error to the caller.
As a result, we never make it to the second pass.

One obvious way of fixing this would be to teach
interpret_upstream_mark to simply report "no, this isn't an
upstream" in such a case. However, that would make the
error-reporting for legitimate upstream cases significantly
worse. Something like "bogus@{upstream}" would simply report
"unknown revision: bogus@{upstream}", while the current code
diagnoses a wide variety of possible misconfigurations (no
such branch, branch exists but does not have upstream, etc).

However, we can take advantage of the fact that a branch
name cannot contain a colon. Therefore even if we find an
upstream mark, any prefix with a colon must mean that
the upstream mark we found is actually a pathname, and
should be disregarded completely. This patch implements that
logic.

Ramkumar Ramachandra 17bf4ff3cd sha1_name: fix error message for @{u}
Currently, when no (valid) upstream is configured for a branch, you get
an error like:

  $ git show @{u}
  error: No upstream configured for branch 'upstream-error'
  error: No upstream configured for branch 'upstream-error'
  fatal: ambiguous argument '@{u}': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'

The "error: " line actually appears twice, and the rest of the error
message is useless.  In sha1_name.c:interpret_branch_name(), there is
really no point in processing further if @{u} couldn't be resolved, and
we might as well die() instead of returning an error().  After making
this change, you get:

  $ git show @{u}
  fatal: No upstream configured for branch 'upstream-error'

Also tweak a few tests in t1507 to expect this output.

This only turns error() that may be called after we know we are
dealing with an @{upstream} marker into die(), without touching
silent error returns "return -1" from the function.  Any caller that
wants to handle an error condition itself will not be hurt by this
change, unless they want to see the message from error() and then
exit silently without giving its own message, which needs to be
fixed anyway.

Zbigniew Jędrzejewski-Szmek 17c82211ec Be more specific if upstream branch is not tracked
If the branch configured as upstream didn't have a local tracking
branch, git said "Upstream branch not found". We can be more helpful,
and separate the cases when upstream is not configured, and when it is
configured, but the upstream branch is not tracked in a local branch.

The following configuration leads to the second scenario:

    [remote "origin"]
    	    url = ...
            fetch = refs/heads/master
    [branch "master"]
            remote = origin
            merge = refs/heads/master

'git pull' will work on master, but master@{upstream} is not defined.

which is true but not very helpful, check that there's no
refs/heads/barnhc_wiht_tpyo and tell it to the user.

Zbigniew Jędrzejewski-Szmek 9884e67f9d Provide branch name in error message when using @{u}
When using @{u} or @{upstream} it is common to omit the branch name,
implying current branch. If the upstream is not configured, the error
message was "No upstream branch found for ''".

When resolving '@{u}', branch_get() is called, which almost always
returns a description of a branch. This allows us to use a branch name
in the error message, even if the user said something like '@{u}'.

The only case when branch_get() returns NULL is when HEAD points to so
something which is not a branch. Of course this also means that no
upstream is configured, but it is better to directly say that HEAD
does not point to a branch.

Zbigniew Jędrzejewski-Szmek 1b4aee94aa t1507: add tests to document @{upstream} behaviour
In preparation for future changes, add tests which show error messages
with @{upstream} in various conditions:

- test branch@{u} with . as remote
- check error message for branch@{u} on a branch with
  * no upstream,
  * on a branch with a configured upstream which doesn't have a
    remote-tracking branch
- check error message for branch@{u} when branch 'branch' does not
  exist
- check error message for @{u} without the branch name

Right now the messages are very similar, but various cases can and
will be distinguished.

Note: test_i18ncmp is not used, because currently error output is not
internationalized. test_cmp will be switched to test_i18ncmp in a later
patch, when error messages are internationalized.

Matthieu Moy 13931236b9 Change incorrect "remote branch" to "remote tracking branch" in C code
(Just like we did for documentation already)

In the process, we change "non-remote branch" to "branch outside the
refs/remotes/ hierarchy" to avoid the ugly "non-remote-tracking branch".
The new formulation actually corresponds to how the code detects this
case (i.e. prefixcmp(refname, "refs/remotes")).

Also, we use 'remote-tracking branch' in generated merge messages (by
merge an fmt-merge-msg).
