When compiling the documentation, asciidoc thinks a backtick surrounded
by whitespace shouldn't be interpreted as marking the start or end of a
literal. In most cases, that's useful behaviour, but in the git-pull
documentation it means asciidoc is failing to correctly detect which
text should be monospaced and which shouldn't.
To avoid this, remove the extraneous spaces from the text to be
monospaced. It would also be possible to fix the formatting by
switching to asciidoc's ++ monospace format markers and still have the
space characters included in the monospace text, but the spaces aren't
necessary and not having them keeps the markup simpler.
Also include a minor grammar fix suggested by Jeff while we're changing

When `git pull --rebase --autostash` in a dirty repository resulted in a
fast-forward, nothing was being autostashed and the pull failed. This
was due to a shortcut to avoid running rebase when we can fast-forward,
but autostash is ignored on that codepath.
Now we will only take the shortcut if autostash is not in effect.
Based on a few tests against the git.git repo, the shortcut does not
seem to give us significant performance benefits, on Linux at least.

We already have free_refspec(), a public function which does
the same thing as the static free_refspecs(). Let's just
keep one. There are two minor differences between the
functions:
1. free_refspecs() is a noop when the refspec argument is
NULL. This probably doesn't matter in practice. The
nr_refspec parameter would presumably be 0 in that
case, skipping the loop. And free(NULL) is explicitly
OK. But it doesn't hurt for us to port this extra
safety to free_refspec(), as one of the callers passes
a funny "i+1" count.
2. The order of arguments is reversed between the two
functions. This patch uses the already-public order of
free_refspec(), as it matches the argument order on the
parsing side.

Change all the "TRANSLATORS: [...]" comments in the C code to use the
regular Git coding style, and amend the style guide so that the
example there uses that style.
This custom style was necessary back in 2010 when the gettext support
was initially added, and was subsequently documented in commit
cbcfd4e3ea ("i18n: mention "TRANSLATORS:" marker in
Documentation/CodingGuidelines", 2014-04-18).
GNU xgettext hasn't had the parsing limitation that necessitated this
exception for almost 3 years. Since its 0.19 release on 2014-06-02
it's been able to recognize TRANSLATOR comments in the standard Git
comment syntax[1].
Usually we'd like to keep compatibility with software that's that
young, but in this case literally the only person who needs to be
using a gettext newer than 3 years old is Jiang Xin (the only person
who runs & commits "make pot" results), so I think in this case we can
make an exception.
This xgettext parsing feature was added after a thread on the Git
mailing list[2] which continued on the bug-gettext[3] list, but we
never subsequently changed our style & styleguide, do so.
There are already longstanding changes in git that use the standard
comment style & have their TRANSLATORS comments extracted properly
without getting the literal "*"'s mixed up in the text, as would
happen before xgettext 0.19.
Commit 7ff2683253 ("builtin-am: implement -i/--interactive",
2015-08-04) added one such comment, which in commit df0617bfa7 ("l10n:
git.pot: v2.6.0 round 1 (123 new, 41 removed)", 2015-09-05) got picked
up in the po/git.pot file with the right format, showing that Jiang
already runs a modern xgettext.
The xgettext parser does not handle the sort of non-standard comment
style that I'm amending here in sequencer.c, but that isn't standard
Git comment syntax anyway. With this change to sequencer.c & "make
pot" the comment in the pot file is now correct:
#. TRANSLATORS: %s will be "revert", "cherry-pick" or
-#. * "rebase -i".
+#. "rebase -i".

If the user provides "-h" on the command line, then our
parse_options() invocation will show a usage message and
quit. But if "-h" is the only argument, the git wrapper
behaves specially: it ignores our RUN_SETUP flag and calls
cmd_am() without having done repository setup at all. This
is due to 99caeed05 (Let 'git <command> -h' show usage
without a git dir, 2009-11-09).
Before cmd_am() calls parse_options(), though, it runs a few
other setup functions. One of these is am_state_init(),
which uses git_pathdup() to set up the default rebase-apply
path. But calling git_pathdup() when we haven't done
repository setup will fall back to using ".git". That's
mostly harmless (since we won't use the value anyway), but
is forbidden since b1ef400eec ("setup_git_env: avoid blind
fall-back to ".git"", 2016-10-20), and we now BUG().
We can't easily move that setup to after the parse_options()
call; the point is to set up defaults that are overwritten
by the option parsing. Instead, we'll detect the "-h" case
early and show the usage then. This matches the behavior of
other builtins which have a similar setup-ordering issue
(e.g., git-branch).

If we successfully parse a symref value like
"HEAD:refs/heads/master", we add the result to a string
list. But because the string list is marked
STRING_LIST_INIT_DUP, the string list code will make a copy
of the string and add the copy.
This patch fixes it by adding the entry with
string_list_append_nodup(), which lets the string list take
ownership of our newly allocated string. There are two
alternatives that seem like they would work, but aren't the
right solution.
The first is to initialize the list with the "NODUP"
initializer. That would avoid the copy, but then the string
list would not realize that it owns the strings. When we
eventually call string_list_clear(), it would not free the
strings, causing a leak.
The second option would be to use the normal
string_list_append(), but free the local copy in our
function. We can't do this because the local copy actually
contains _two_ strings; the symref name and its target. We
point to the target pointer via the "util" field, and its
memory must last as long as the string list does.
You may also wonder whether it's safe to ever free the local
copy, since the target points into it. The answer is yes,
because we duplicate it in annotaate_refs_with_symref_info
before clearing the string list.

Use is_dir_sep() to check for both slashes and backslashes on Windows.
This was discovered while playing with Duy's patches that warn after
fopen() failures. The functions that read the branches and remotes
files are protected by a valid_remote_nick() check. Without this
change, a Windows style absolute path is incorrectly regarded as
nickname and is concatenated to a prefix and used with fopen(). This
triggers warnings because a colon in a path name is not allowed:

When we diff a blob against a working tree file like:

we always use the working tree filename for both sides of

same anyway, as above. And until recently, we used the
"name" for the blob, not the path, which would have the
messy "HEAD:" on the beginning.
But when they don't match, like:
git diff HEAD:old_path new_path
it makes sense to show both names.
This patch uses the blob's path field if it's available, and

There's a subtle distinction between "name" and "path" for a

When we diff blobs directly, we use "name", but "path" is
more likely to be useful to the user (it will find the
correct .gitattributes, and give them a saner diff header).
We still have to fall back to using the name for some cases

a custom "struct blobinfo". But the pending array entry
already has all of this information (and more, which we'll
use in future patches). Let's just pass the original entry
instead.
In practice, these two blobs are probably adjacent in the
revs->pending array, and we could just pass the whole array.

separately and put it into another array, so we'll continue
to do so and make our own array-of-pointers.

If the revision parser sees an argument like tree:path, we
parse it down to the correct blob (or tree), but throw away
the "path" portion. Let's ask get_sha1_with_context() to
record it, and pass it along in the pending array.
This will let programs like git-diff which rely on the
revision-parser show more accurate paths.
Note that the implementation is a little tricky; we have to
make sure we free oc.path in all code paths. For handle_dotdot(),
we can piggy-back on the existing cleanup-wrapper pattern.
The real work happens in handle_dotdot_1(), but the
handle_dotdot() wrapper makes sure that the path is freed no
matter how we exit the function (and for that reason we make
sure that the object_context struct is zero'd, so if we fail
to even get to the get_sha1_with_context() call, we just end

The git-diff command can directly compare two blobs (or a
blob and a file), but we don't test this at all. Let's add
some basic tests that reveal a few problems.
There are basically four interesting inputs:
1. sha1 against sha1 (where diff has no information beyond
the contents)
2. tree:path against tree:path (where it can get
information via get_sha1_with_context)
3. Same as (2), but using the ".." range syntax
4. tree:path against a filename
And beyond generating a sane diff, we care about a few
little bits: which paths they show in the diff header, and
whether they correctly pick up a mode change.
They should all be able to show a mode except for (1),
though note that case (3) is currently broken.
For the headers, we would ideally show the path within the
tree if we have it, making:
git diff a:path b:path
look the same as:
git diff a b -- path
We can't always do that (e.g., in the direct sha1/sha1 diff,
we have no path to show), in which case we should fall back
to the name that resolved to the blob (which is nonsense
from the repository's perspective, but is the best we can
do).
Aside from the fallback case in (1), none of the cases get
this right. Cases (2) and (3) always show the full
tree:path, even though we should be able to know just the
"path" portion.
Case (4) picks up the filename path, but assigns it to
_both_ sides of the diff. So this works for:
git diff tree:path path
but not for:
git diff tree:other_path path
The appropriate tests are marked to expect failure.

When a sha1 lookup returns the tree path via "struct
object_context", it just copies it into a fixed-size buffer.
This means the result can be truncated, and it means our
"struct object_context" consumes a lot of stack space.
Instead, let's allocate a string on the heap. Because most
callers don't care about this information, we'll avoid doing
it by default (so they don't all have to start calling
free() on the result). There are basically two options for
the caller to signal to us that it's interested:
1. By setting a pointer to storage in the object_context.
2. By passing a flag in another parameter.
Doing (1) would match the way that sha1_object_info_extended()
works. But it would mean that every caller would have to
initialize the object_context, which they don't currently
have to do.
This patch does (2), and adds a new bit to the function's
flags field. All of the callers that look at the "path"
field are updated to pass the new flag.

The get_sha1_with_context() function zeroes out the
oc->symlink_path strbuf, but doesn't use strbuf_init() to
set up the usual invariants (like pointing to the slopbuf).
We don't actually write to the oc->symlink_path strbuf
unless we call get_tree_entry_follow_symlinks(), and that
function does initialize it. However, readers may still look
at the zero'd strbuf.
In practice this isn't a triggerable bug. The only caller
that looks at it only does so when the mode we found is 0.
This doesn't happen for non-tree-entries (where we return
S_IFINVALID). A broken tree entry could have a mode of 0,
but canon_mode() quietly rewrites that into S_IFGITLINK.
So the "0" mode should only come up when we did indeed find
a symlink.
This is mostly just an accident of how the code happens to
work, though. Let's future-proof ourselves to make sure the
strbuf is properly initialized for all calls (it's only a

- eliminate a goto which wasn't actually used for control
flow, but only to avoid duplicating a few lines

function)
- use early returns instead of deep nesting
- consistently name all variables for the left-hand side

specially. We detect it by noticing that both sides of the

range.
While correct, this makes the code overly complicated. We
can just detect ".." up front before we try to do further
parsing. This avoids having to de-munge the NUL from dotdot,
and lets us eliminate an extra const array (which we needed
only to do direct pointer comparisons).
It also removes the one code path from the range-parsing
