Code cleanup to avoid using redundant refspecs while fetching with
the --tags option.
* jt/fetch-no-redundant-tag-fetch-map:
fetch: do not redundantly calculate tag refmap

builtin/fetch.c redundantly calculates refmaps for tags twice. Remove
the first calculation.
This is only a code simplification and slight performance improvement -
the result is unchanged, as the redundant refmaps are subsequently
removed by the invocation to "ref_remove_duplicates" anyway.
This was introduced in commit c5a84e9 ("fetch --tags: fetch tags *in
addition to* other stuff", 2013-10-29) when modifying the effect of the
--tags parameter to "git fetch". The refmap-for-tag calculation was
copied instead of moved.

A lazy "git push" without refspec did not internally use a fully
specified refspec to perform 'current', 'simple', or 'upstream'
push, causing unnecessary "ambiguous ref" errors.

When the user does the lazy "git push" with no parameters with
push.default set to either "upstream", "simple" or "current",
we internally generated a refspec that has the current branch name
on the source side and used it to push.
However, the branch name (say "test") may be an ambiguous refname in
the context of the source repository---there may be a tag with the
same name, for example. This would trigger an unnecessary error
without any fault on the end-user's side.
Be explicit and give a full refname as the source side to avoid the
ambiguity. The destination side when pushing with the "current"
sent only the name of the branch and forcing the receiving end to
guess, which is the same issue. Be explicit there as well.

"git index-pack --stdin" needs an access to an existing repository,
but "git index-pack file.pack" to generate an .idx file that
corresponds to a packfile does not.
* jk/index-pack-wo-repo-from-stdin:
index-pack: skip collision check when not in repository
t: use nongit() function where applicable

You can run "git index-pack path/to/foo.pack" outside of a
repository to generate an index file, or just to verify the
contents. There's no point in doing a collision check, since
we obviously do not have any objects to collide with.
The current code will blindly look in .git/objects based on
the result of setup_git_env(). That effectively gives us the
right answer (since we won't find any objects), but it's a
waste of time, and it conflicts with our desire to
eventually get rid of the "fallback to .git" behavior of
setup_git_env().

The index-pack builtin is marked as RUN_SETUP_GENTLY,
because it's perfectly fine to index a pack in the
filesystem outside of any repository. However, --stdin mode
will write the result to the object database, which does not
make sense outside of a repository. Doing so creates a bogus
".git" directory with nothing in it except the newly-created
pack and its index.
Instead, let's flag this as an error and abort.

Unlike "git am --abort", "git cherry-pick --abort" moved HEAD back
to where cherry-pick started while picking multiple changes, when
the cherry-pick stopped to ask for help from the user, and the user
did "git reset --hard" to a different commit in order to re-attempt
the operation.

The error message tells the user that something went terribly wrong
and the --abort could not be performed. But the --abort is performed,
only without rewinding. By simply changing the error into a warning,
we indicate the user that she must not try something like
"git am --abort --force", instead she just has to check the HEAD.

"git pull --rebase", when there is no new commits on our side since
we forked from the upstream, should be able to fast-forward without
invoking "git rebase", but it didn't.

"git pull --rebase" always runs "git rebase" after fetching the
commit to serve as the new base, even when the new base is a
descendant of the current HEAD, i.e. we haven't done any work.
In such a case, we can instead fast-forward to the new base without
invoking the rebase process.

"git commit --allow-empty --only" (no pathspec) with dirty index
ought to be an acceptable way to create a new commit that does not

This is required by git-worktree.txt, stating that the main worktree is
the first line (especially in --porcelain mode when we can't just change
behavior at will).
There's only one case when get_worktrees() may skip main worktree, when
parse_ref() fails. Update the code so that we keep first item as main
worktree and return something sensible in this case:
- In user-friendly mode, since we're not constraint by anything,
returning "(error)" should do the job (we already show "(detached
HEAD)" which is not machine-friendly). Actually errors should be
printed on stderr by parse_ref() (*)
- In plumbing mode, we do not show neither 'bare', 'detached' or
'branch ...', which is possible by the format description if I read
it right.
Careful readers may realize that when the local variable "head_ref" in
get_main_worktree() is emptied, add_head_info() will do nothing to
wt->head_sha1. But that's ok because head_sha1 is zero-ized in the
previous patch.
(*) Well, it does not. But it's supposed to be a stop gap implementation
until we can reuse refs code to parse "ref: " stuff in HEAD, from
resolve_refs_unsafe(). Now may be the time since refs refactoring is
mostly done.

"git rev-parse --symbolic" failed with a more recent notation like
"HEAD^-1" and "HEAD^!".

The try_parent_shorthands() function shows each parent via
show_rev(). We pass the correct parent sha1, but our "name"
parameter still points at the original refname. So asking
for a regular rev-parse works fine (it prints the sha1s),
but asking for the symbolic name gives nonsense like:
$ git rev-parse --symbolic HEAD^-1
HEAD
^HEAD
which is always an empty set of commits. Asking for "^!" is
likewise broken, with the added bonus that its prints ^HEAD
for _each_ parent. And "^@" just prints HEAD repeatedly.
Arguably it would be correct to just pass NULL as the name
here, and always get the parent expressed as a sha1. The
"--symbolic" documentaton claims only "as close to the
original input as possible", and we certainly fallback to
sha1s where necessary. But it's pretty easy to generate a
symbolic name on the fly from the original.

The way "git stripspace" reads the configuration was not quite
kosher, in that the code forgot to probe for a possibly existing
repository (note: stripspace is designed to be usable outside the
repository as well). It read .git/config only when it was run from
the top-level of the working tree by accident. A recent change
b9605bc4f2 ("config: only read .git/config from configured repos",
2016-09-12) stopped reading the repository-local configuration file
".git/config" unless the repository discovery process is done, so
that .git/config is never read even when run from the top-level,
exposing the old bug more.
When rebasing interactively with a commentChar defined in the
current repository's config, the help text at the bottom of the edit
script potentially used an incorrect comment character. This was not
only funny-looking, but also resulted in tons of warnings like this
one:

This function used to have the caller pass in the current

In 55c4a6730, that logic moved to validate_new_branchname(),
which just resolves HEAD itself. The parameter to
create_branch is now unused.

Git generally does not explicitly close file descriptors that were
open in the parent process when spawning a child process, but most
of the time the child does not want to access them. As Windows does
not allow removing or renaming a file that has a file descriptor
open, a slow-to-exit child can even break the parent process by
holding onto them. Use O_CLOEXEC flag to open files in various
codepaths.

This function is meant to be used when reading from files in the
object store, and the original objective was to avoid smudging atime
of loose object files too often, hence its name. Because we'll be
extending its role in the next commit to also arrange the file
descriptors they return auto-closed in the child processes, rename
it to lose "noatime" part that is too specific.

When new paths were added by "git add -N" to the index, it was
enough to circumvent the check by "git commit" to refrain from
making an empty commit without "--allow-empty". The same logic
prevented "git status" to show such a path as "new file" in the
"Changes not staged for commit" section.
* nd/ita-empty-commit:
commit: don't be fooled by ita entries when creating initial commit
commit: fix empty commit creation when there's no changes but ita entries
diff: add --ita-[in]visible-in-index
diff-lib: allow ita entries treated as "not yet exist in index"

ita entries are dropped at tree generation phase. If the entire index
consists of just ita entries, the result would be a a commit with no
entries, which should be caught unless --allow-empty is specified. The
test "!!active_nr" is not sufficient to catch this.

If i-t-a entries are present and there is no change between the index
and HEAD i-t-a entries, index_differs_from() still returns "dirty, new
entries" (aka, the resulting commit is not empty), but cache-tree will
skip i-t-a entries and produce the exact same tree of current
commit.
index_differs_from() is supposed to catch this so we can abort
git-commit (unless --no-empty is specified). Update it to optionally
ignore i-t-a entries when doing a diff between the index and HEAD so
that it would return "no change" in this case and abort commit.

The subcommands are used exactly once, at the very beginning of
sequencer_pick_revisions(), to determine what to do. This is an
unnecessary level of indirection: we can simply call the correct
function to begin with. So let's do that.
While at it, ensure that the subcommands return an error code so that
they do not have to die() all over the place (bad practice for library
functions...).

The sequencer is our attempt to lib-ify cherry-pick. Yet it behaves
like a one-shot command when it reads its configuration: memory is
allocated and released only when the command exits.
This is kind of okay for git-cherry-pick, which *is* a one-shot
command. All the work to make the sequencer its work horse was
done to allow using the functionality as a library function, though,
including proper clean-up after use.
To remedy that, take custody of the option values in question,
allocating and duping literal constants as needed and freeing them
at end.

This change is not completely faithful: instead of initializing all fields
to 0, we choose to initialize command and subcommand to -1 (instead of
defaulting to REPLAY_REVERT and REPLAY_NONE, respectively). Practically,
it makes no difference at all, but future-proofs the code to require
explicit assignments for both fields.

A minor regression fix for "git submodule".

This is similar to the previous patch, though no user reported a bug and
I could not find a regressive behavior.
However it is a good thing to be strict on the output and for that we
always omit a trailing slash.

Before 63e95beb0 (2016-04-15, submodule: port resolve_relative_url from
shell to C), it did not matter if the superprojects URL had a trailing
slash or not. It was just chopped off as one of the first steps
(The "remoteurl=${remoteurl%/}" near the beginning of
resolve_relative_url(), which was removed in said commit).
When porting this to the C version, an off-by-one error was introduced
and we did not check the actual last character to be a slash, but the
NULL delimiter.
Reintroduce the behavior from before 63e95beb0, to ignore the trailing
slash.

Some code paths want to format multiple abbreviated sha1s in
the same output line. Because we use a single static buffer
for our return value, they have to either break their output
into several calls or allocate their own arrays and use
find_unique_abbrev_r().
Intead, let's mimic sha1_to_hex() and use a ring of several
buffers, so that the return value stays valid through
multiple calls. This shortens some of the callers, and makes
it harder to for them to make a silly mistake.

"git push" and "git fetch" reports from what old object to what new
object each ref was updated, using abbreviated refnames, and they
attempt to align the columns for this and other pieces of
information. The way these codepaths compute how many display
columns to allocate for the object names portion of this output has
been updated to match the recent "auto scale the default
abbreviation length" change.
* jc/abbrev-auto:
transport: compute summary-width dynamically
transport: allow summary-width to be computed dynamically
fetch: pass summary_width down the callchain
transport: pass summary_width down the callchain

Now we have identified three callchains that have a set of refs that
they want to show their <old, new> object names in an aligned output,
we can replace their reference to the constant TRANSPORT_SUMMARY_WIDTH
with a helper function call to transport_summary_width() that takes
the set of ref as a parameter. This step does not yet iterate over
the refs and compute, which is left as an exercise to the readers.
