Genki Sky a6c612b528 rebase: add --allow-empty-message option
This option allows commits with empty commit messages to be rebased,
matching the same option in git-commit and git-cherry-pick. While empty
log messages are frowned upon, sometimes one finds them in older
repositories (e.g. translated from another VCS [0]), or have other
reasons for desiring them. The option is available in git-commit and
git-cherry-pick, so it is natural to make other git tools play nicely
with them. Adding this as an option allows the default to be "give the
user a chance to fix", while not interrupting the user's workflow
otherwise [1].

  [0]: https://stackoverflow.com/q/8542304
  [1]: https://public-inbox.org/git/7vd33afqjh.fsf@alter.siamese.dyndns.org/

To implement this, add a new --allow-empty-message flag. Then propagate
it to all calls of 'git commit', 'git cherry-pick', and 'git rebase--helper'
within the rebase scripts.

Thomas Gummerer 1cf823fb68 reset --hard: make use of the pretty machinery
reset --hard currently uses its own logic for printing the first line of
the commit message in its output.  Instead of just using the first line,
use the pretty machinery to create the output.

In addition to the easier to follow code, this makes the output more
consistent with other commands that print the title of the commit, such
as 'git commit --oneline' or 'git checkout', which both use
'pp_commit_easy()' with the CMIT_FMT_ONELINE modifier.

It is a slight change of the output if the second line of the commit
message is not a blank line, i.e. if the commit message is

    foo
    bar

previously we would print "HEAD is now at 000000 foo", while after
this change we print "HEAD is now at 000000 foo bar", same as 'git log
--oneline' shows "000000 foo bar".

So this does make the output more consistent with other commands, and
'reset' is a porcelain command, so nobody should be parsing the output
in scripts.

The current behaviour dates back to 0e5a7faa3a ("Make "git reset" a
builtin.", 2007-09-11), so I assume (without digging into the old
codebase too much) that the logic was implemented because there was
no convenience function such as 'pp_commit_easy' that would do this
already.

Stefan Beller cf63051ada diff: introduce DIFF_PICKAXE_KINDS_MASK
Currently the check whether to perform pickaxing is done via checking
`diffopt->pickaxe`, which contains the command line argument that we
want to pickaxe for. Soon we'll introduce a new type of pickaxing, that
will not store anything in the `.pickaxe` field, so let's migrate the
check to be dependent on pickaxe_opts.

It is not enough to just replace the check for pickaxe by pickaxe_opts,
because flags might be set, but pickaxing was not requested ('-i').
To cope with that, introduce a mask to check only for the bits indicating
the modes of operation.

Jeff King d45420c1c8 clone: do not clean up directories we didn't create
Once upon a time, git-clone would refuse to write into a
directory that it did not itself create. The cleanup
routines for a failed clone could therefore just remove the
git and worktree dirs completely.

In 55892d2398 (Allow cloning to an existing empty directory,
2009-01-11), we learned to write into an existing directory.
Which means that doing:

  mkdir foo
  git clone will-fail foo

ends up deleting foo. This isn't a huge catastrophe, since
by definition foo must be empty. But it's somewhat
confusing; we should leave the filesystem as we found it.

Because we know that the only directory we'll write into is
an empty one, we can handle this case by just passing the
KEEP_TOPLEVEL flag to our recursive delete (if we could
write into populated directories, we'd have to keep track of
what we wrote and what we did not, which would be much
harder).

Note that we need to handle the work-tree and git-dir
separately, though, as only one might exist (and the new
tests in t5600 cover all cases).

Jeff King f9e377adc0 clone: factor out dir_exists() helper
Two parts of git-clone's setup logic check whether a
directory exists, and they both call stat directly with the
same scratch "struct stat" buffer. Let's pull that into a
helper, which has a few advantages:

  - it makes the purpose of the stat calls more obvious

  - it makes it clear that we don't care about the
    information in "buf" remaining valid

  - if we later decide to make the check more robust (e.g.,
    complaining about non-directories), we can do it in one
    place

Note that we could just use file_exists() for this, which
has identical code. But we specifically care about
directories, so this future-proofs us against that function
later getting more picky about seeing actual files.

René Scharfe a9a03fa0d7 checkout: avoid using the rev_info flag leak_pending
The leak_pending flag is so awkward to use that multiple comments had to
be added around each occurrence.  We only use it for remembering the
commits whose marks we have to clear after checking if the old HEAD is
detached.  This is easy, though: We need to do that for the old commit,
the new one -- and for all refs.

Don't bother tracking exactly which commits need their flags cleared,
just nuke all we have in-core.  This change is safe because refs can
point at anything, so other program parts can't depend on any kept flags
anyway.  And since all refs are loaded we have to basically deal with
all commits anyway, so performance should not be negatively impacted.

Daniel Knittl-Frank 1bba00130a describe: prepend "tags/" when describing tags with embedded name
The man page of the "git describe" command explains the expected
output when using the --all option, i.e. the full reference path is
shown, including heads/ or tags/ prefix.

When 212945d4a8 ("Teach git-describe
to verify annotated tag names before output") made Git favor the
embedded name of annotated tags, it accidentally changed the output
format when the --all flag is given, only printing the tag's name
without the prefix.

Check if --all was specified and re-add the "tags/" prefix for this
special case to fix the regresssion.

Ævar Arnfjörð Bjarmason 30884c9afc commit: add support for --fixup <commit> -m"<extra message>"
Add support for supplying the -m option with --fixup. Doing so has
errored out ever since --fixup was introduced. Before this, the only
way to amend the fixup message while committing was to use --edit and
amend it in the editor.

The use-case for this feature is one of:

 * Leaving a quick note to self when creating a --fixup commit when
   it's not self-evident why the commit should be squashed without a
   note into another one.

 * (Ab)using the --fixup feature to "fix up" commits that have already
   been pushed to a branch that doesn't allow non-fast-forwards,
   i.e. just noting "this should have been part of that other commit",
   and if the history ever got rewritten in the future the two should
   be combined.

   In such a case you might want to leave a small message,
   e.g. "forgot this part, which broke XYZ".

With this, --fixup <commit> -m"More" -m"Details" will result in a
commit message like:

    !fixup <subject of <commit>>

    More

    Details

The reason the test being added here seems to squash "More" at the end
of the subject line of the commit being fixed up is because the test
code is using "%s%b" so the body immediately follows the subject, it's
not a bug in this code, and other tests t7500-commit.sh do the same
thing.

When the --fixup option was initially added the "Option -m cannot be
combined" error was expanded from -c, -C and -F to also include
--fixup[1]

Those options could also support combining with -m, but given what
they do I can't think of a good use-case for doing that, so I have not
made the more invasive change of splitting up the logic in commit.c to
first act on those, and then on -m options.

Stefan Beller 644eb60bd0 builtin/describe.c: describe a blob
Sometimes users are given a hash of an object and they want to
identify it further (ex.: Use verify-pack to find the largest blobs,
but what are these? or [1])

When describing commits, we try to anchor them to tags or refs, as these
are conceptually on a higher level than the commit. And if there is no ref
or tag that matches exactly, we're out of luck.  So we employ a heuristic
to make up a name for the commit. These names are ambiguous, there might
be different tags or refs to anchor to, and there might be different
path in the DAG to travel to arrive at the commit precisely.

When describing a blob, we want to describe the blob from a higher layer
as well, which is a tuple of (commit, deep/path) as the tree objects
involved are rather uninteresting.  The same blob can be referenced by
multiple commits, so how we decide which commit to use?  This patch
implements a rather naive approach on this: As there are no back pointers
from blobs to commits in which the blob occurs, we'll start walking from
any tips available, listing the blobs in-order of the commit and once we
found the blob, we'll take the first commit that listed the blob. For
example

  git describe --tags v0.99:Makefile
  conversion-901-g7672db20c2:Makefile

tells us the Makefile as it was in v0.99 was introduced in commit 7672db20.

The walking is performed in reverse order to show the introduction of a
blob rather than its last occurrence.

Phillip Wood 28d6daed4f sequencer: improve config handling
The previous config handling relied on global variables, called
git_default_config() even when the key had already been handled by
git_sequencer_config() and did not initialize the diff configuration
variables. Improve this by: i) loading the default values for message
cleanup and gpg signing of commits into struct replay_opts;
ii) restructuring the code to return immediately once a key is
handled; and iii) calling git_diff_basic_config(). Note that
unfortunately it is not possible to return early if the key is handled
by git_gpg_config() as it does not indicate to the caller if the key
has been handled or not.

The sequencer should probably have been calling
git_diff_basic_config() before as it creates a patch when there are
conflicts. The shell version uses 'diff-tree' to create the patch so
calling git_diff_basic_config() should match that. Although 'git
commit' calls git_diff_ui_config() I don't think the output of
print_commit_summary() is affected by anything that is loaded by that
as print_commit_summary() always turns on rename detection so would
ignore the value in the user's configuration anyway. The other values
loaded by git_diff_ui_config() are about the formatting of patches so
are not relevant to print_commit_summary().

Eric Sunshine b3b05971c1 clone: support 'clone --shared' from a worktree
When worktree functionality was originally implemented, the possibility
of 'clone --local' from within a worktree was overlooked, with the
result that the location of the "objects" directory of the source
repository was computed incorrectly, thus the objects could not be
copied or hard-linked by the clone. This shortcoming was addressed by
744e469755 (clone: allow --local from a linked checkout, 2015-09-28).

However, the related case of 'clone --shared' (despite being handled
only a few lines away from the 'clone --local' case) was not fixed by
744e469755, with a similar result of the "objects" directory location
being incorrectly computed for insertion into the 'alternates' file.
Fix this.

Jonathan Tan df11e19648 rev-list: support termination at promisor objects
Teach rev-list to support termination of an object traversal at any
object from a promisor remote (whether one that the local repo also has,
or one that the local repo knows about because it has another promisor
object that references it).

This will be used subsequently in gc and in the connectivity check used
by fetch.

For efficiency, if an object is referenced by a promisor object, and is
in the local repo only as a non-promisor object, object traversal will
not stop there. This is to avoid building the list of promisor object
references.

(In list-objects.c, the case where obj is NULL in process_blob() and
process_tree() do not need to be changed because those happen only when
there is a conflict between the expected type and the existing object.
If the object doesn't exist, an object will be synthesized, which is
fine.)

Jonathan Tan 8b4c0103a9 sha1_file: support lazily fetching missing objects
Teach sha1_file to fetch objects from the remote configured in
extensions.partialclone whenever an object is requested but missing.

The fetching of objects can be suppressed through a global variable.
This is used by fsck and index-pack.

However, by default, such fetching is not suppressed. This is meant as a
temporary measure to ensure that all Git commands work in such a
situation. Future patches will update some commands to either tolerate
missing objects (without fetching them) or be more efficient in fetching
them.

In order to determine the code changes in sha1_file.c necessary, I
investigated the following:
 (1) functions in sha1_file.c that take in a hash, without the user
     regarding how the object is stored (loose or packed)
 (2) functions in packfile.c (because I need to check callers that know
     about the loose/packed distinction and operate on both differently,
     and ensure that they can handle the concept of objects that are
     neither loose nor packed)

(1) is handled by the modification to sha1_object_info_extended().

For (2), I looked at for_each_packed_object and others.  For
for_each_packed_object, the callers either already work or are fixed in
this patch:
 - reachable - only to find recent objects
 - builtin/fsck - already knows about missing objects
 - builtin/cat-file - warning message added in this commit

Callers of the other functions do not need to be changed:
 - parse_pack_index
   - http - indirectly from http_get_info_packs
   - find_pack_entry_one
     - this searches a single pack that is provided as an argument; the
       caller already knows (through other means) that the sought object
       is in a specific pack
 - find_sha1_pack
   - fast-import - appears to be an optimization to not store a file if
     it is already in a pack
   - http-walker - to search through a struct alt_base
   - http-push - to search through remote packs
 - has_sha1_pack
   - builtin/fsck - already knows about promisor objects
   - builtin/count-objects - informational purposes only (check if loose
     object is also packed)
   - builtin/prune-packed - check if object to be pruned is packed (if
     not, don't prune it)
   - revision - used to exclude packed objects if requested by user
   - diff - just for optimization

been renamed "away". A similar message is shown when trying to create

branch. This is not correct and may confuse the user.

So, update the warning message shown to be more precise that only a copy
of the misnamed branch has been created. It's better to show the warning

Implementation note: The newly-created worktree may reference a branch
or be detached. In the latter case, a commit lookup is performed, though
the result is used only in a boolean sense to (a) determine if the
commit actually exists, and (b) assign either the branch name or commit
ID to HEAD. Since the post-commit hook needs to know the ID of the
checked-out commit, the lookup now needs to be done in all cases, rather
than only when detached. Consequently, a new boolean is needed to handle
(b) since the lookup result itself can no longer perform that role.

Brandon Williams fd66bcc31f diff-tree: read the index so attribute checks work in bare repositories
A regression was introduced in 557a5998d (submodule: remove
gitmodules_config, 2017-08-03) to how attribute processing was handled
in bare repositories when running the diff-tree command.

By default the attribute system will first try to read ".gitattribute"
files from the working tree and then falls back to reading them from the
index if there isn't a copy checked out in the worktree.  Prior to
557a5998d the index was read as a side effect of the call to
'gitmodules_config()' which ensured that the index was already populated
before entering the attribute subsystem.

Since the call to 'gitmodules_config()' was removed the index is no
longer being read so when the attribute system tries to read from the
in-memory index it doesn't find any ".gitattribute" entries effectively
ignoring any configured attributes.

Fix this by explicitly reading the index during the setup of diff-tree.

Thomas Gummerer 71d6682d8c worktree: add --guess-remote flag to add subcommand
Currently 'git worktree add <path>' creates a new branch named after the
basename of the <path>, that matches the HEAD of whichever worktree we
were on when calling "git worktree add <path>".

It's sometimes useful to have 'git worktree add <path> behave more like
the dwim machinery in 'git checkout <new-branch>', i.e. check if the new
branch name, derived from the basename of the <path>, uniquely matches
the branch name of a remote-tracking branch, and if so check out that
branch and set the upstream to the remote-tracking branch.

Add a new --guess-remote option that enables exactly that behaviour.

Jonathan Tan 88e2f9ed8e introduce fetch-object: fetch one promisor object
Introduce fetch-object, providing the ability to fetch one object from a
promisor remote.

This uses fetch-pack. To do this, the transport mechanism has been
updated with 2 flags, "from-promisor" to indicate that the resulting
pack comes from a promisor remote (and thus should be annotated as such
by index-pack), and "no-dependents" to indicate that only the objects
themselves need to be fetched (but fetching additional objects is
nevertheless safe).

Whenever "no-dependents" is used, fetch-pack will refrain from using any
object flags, because it is most likely invoked as part of a dynamic
object fetch by another Git command (which may itself use object flags).
An alternative to this is to leave fetch-pack alone, and instead update
the allocation of flags so that fetch-pack's flags never overlap with
any others, but this will end up shrinking the number of flags available
to nearly every other Git command (that is, every Git command that
accesses objects), so the approach in this commit was used instead.

This will be tested in a subsequent commit.

Currently, Git does not support repos with very large numbers of objects
or repos that wish to minimize manipulation of certain blobs (for
example, because they are very large) very well, even if the user
operates mostly on part of the repo, because Git is designed on the
assumption that every referenced object is available somewhere in the
repo storage. In such an arrangement, the full set of objects is usually
available in remote storage, ready to be lazily downloaded.

Teach fsck about the new state of affairs. In this commit, teach fsck
that missing promisor objects referenced from the reflog are not an
error case; in future commits, fsck will be taught about other cases.

Brandon Williams eef3df5a93 pathspec: only match across submodule boundaries when requested
Commit 74ed43711f (grep: enable recurse-submodules to work on <tree>
objects, 2016-12-16) taught 'tree_entry_interesting()' to be able to
match across submodule boundaries in the presence of wildcards.  This is
done by performing literal matching up to the first wildcard and then
punting to the submodule itself to perform more accurate pattern
matching.  Instead of introducing a new flag to request this behavior,
commit 74ed43711f overloaded the already existing 'recursive' flag in
'struct pathspec' to request this behavior.

This leads to a bug where whenever any other caller has the 'recursive'
flag set as well as a pathspec with wildcards that all submodules will
be indicated as matches.  One simple example of this is:

	git init repo
	cd repo

	git init submodule
	git -C submodule commit -m initial --allow-empty

	touch "[bracket]"
	git add "[bracket]"
	git commit -m bracket
	git add submodule
	git commit -m submodule

	git rev-list HEAD -- "[bracket]"

Fix this by introducing the new flag 'recurse_submodules' in 'struct
pathspec' and using this flag to determine if matches should be allowed
to cross submodule boundaries.

This fixes https://github.com/git-for-windows/git/issues/1371.

Phillip Wood e47c6cafcb commit: move print_commit_summary() to libgit
Move print_commit_summary() from builtin/commit.c to sequencer.c so it
can be shared with other commands. The function is modified by
changing the last argument to a flag so callers can specify whether
they want to show the author date in addition to specifying if this is
an initial commit.

If the sequencer dies in print_commit_summary() (which can only happen
when cherry-picking or reverting) then neither the todo list nor the
abort safety file are updated to reflect the commit that was just
made. print_commit_summary() can die if:

 - The commit that was just created cannot be found or parsed.

 - HEAD cannot be resolved either because some other process is
   updating it (which is bad news in the middle of a cherry-pick) or
   because it is corrupt.

 - log_tree_commit() cannot read some objects.

In all those cases dying will leave the sequencer in a sane state for
aborting; 'git cherry-pick --abort' will rewind HEAD to the last
successful commit before there was a problem with HEAD or the object
database. If the user somehow fixes the problem and runs 'git
cherry-pick --continue' then the sequencer will try and pick the same
commit again which may or may not be what the user wants depending on
what caused print_commit_summary() to die. If print_commit_summary()
returned an error instead then update_abort_safety_file() would try to
resolve HEAD which may or may not be successful. If it is successful
then running 'git rebase --abort' would not rewind HEAD to the last
successful commit which is not what we want.

Rafael Ascensão 65516f586b log: add option to choose which refs to decorate
When `log --decorate` is used, git will decorate commits with all
available refs. While in most cases this may give the desired effect,
under some conditions it can lead to excessively verbose output.

Introduce two command line options, `--decorate-refs=<pattern>` and
`--decorate-refs-exclude=<pattern>` to allow the user to select which
refs are used in decoration.

When "--decorate-refs=<pattern>" is given, only the refs that match the
pattern are used in decoration. The refs that match the pattern when
"--decorate-refs-exclude=<pattern>" is given, are never used in
decoration.

These options follow the same convention for mixing negative and
positive patterns across the system, assuming that the inclusive default
is to match all refs available.

 (1) if there is no positive pattern given, pretend as if an
     inclusive default positive pattern was given;

 (2) for each candidate, reject it if it matches no positive
     pattern, or if it matches any one of the negative patterns.

The rules for what is considered a match are slightly different from the
rules used elsewhere.

Commands like `log --glob` assume a trailing '/*' when glob chars are
not present in the pattern. This makes it difficult to specify a single
ref.  On the other hand, commands like `describe --match --all` allow
specifying exact refs, but do not have the convenience of allowing
"shorthand refs" like 'refs/heads' or 'heads' to refer to
'refs/heads/*'.

The commands introduced in this patch consider a match if:

  (a) the pattern contains globs chars,
	and regular pattern matching returns a match.

  (b) the pattern does not contain glob chars,
         and ref '<pattern>' exists, or if ref exists under '<pattern>/'

This allows both behaviours (allowing single refs and shorthand refs)
yet remaining compatible with existent commands.

This is similar to ff1e72483 (tag: change default of `pager.tag` to

Martin Ågren d74b541e0b branch: respect pager.branch in list-mode only
Similar to de121ffe5 (tag: respect `pager.tag` in list-mode only,
2017-08-02), use the DELAY_PAGER_CONFIG-mechanism to only respect
`pager.branch` when we are listing branches.

We have two possibilities of generalizing what that earlier commit made
to `git tag`. One is to interpret, e.g., --set-upstream-to as "it does
not use an editor, so we should page". Another, the one taken by this
commit, is to say "it does not list, so let's not page". That is in line
with the approach of the series on `pager.tag` and in particular the
wording in Documentation/git-tag.txt, which this commit reuses for
git-branch.txt.

This fixes the failing test added in the previous commit. Also adapt the
test for whether `git branch --set-upstream-to` respects `pager.branch`.

Haaris Mehmood 5f9674243d config: add --expiry-date
Add --expiry-date as a data-type for config files when
'git config --get' is used. This will return any relative
or fixed dates from config files as timestamps.

This is useful for scripts (e.g. gc.reflogexpire) that work
with timestamps so that '2.weeks' can be converted to a format
acceptable by those scripts/functions.

Following the convention of git_config_pathname(), move
the helper function required for this feature from
builtin/reflog.c to builtin/config.c where other similar
functions exist (e.g. for --bool or --path), and match
the order of parameters with other functions (i.e. output
pointer as first parameter).

Torsten Bögershausen 9472935d81 add: introduce "--renormalize"
Make it safer to normalize the line endings in a repository.
Files that had been commited with CRLF will be commited with LF.

The old way to normalize a repo was like this:

 # Make sure that there are not untracked files
 $ echo "* text=auto" >.gitattributes
 $ git read-tree --empty
 $ git add .
 $ git commit -m "Introduce end-of-line normalization"

The user must make sure that there are no untracked files,
otherwise they would have been added and tracked from now on.

The new "add --renormalize" does not add untracked files:

 $ echo "* text=auto" >.gitattributes
 $ git add --renormalize .
 $ git commit -m "Introduce end-of-line normalization"

Note that "git add --renormalize <pathspec>" is the short form for
"git add -u --renormalize <pathspec>".

While at it, document that the same renormalization may be needed,
whenever a clean filter is added or changed.

Martin Ågren a452d0f4ba builtin/merge-base: free commit lists
In several functions, we iterate through a commit list by assigning
`result = result->next`. As a consequence, we lose the original pointer
and eventually leak the list.

Rewrite the loops so that we keep the original pointers, then call
`free_commit_list()`. Various alternatives were considered:

1) Use `UNLEAK(result)` before the loop. Simple change, but not very
pretty. These would definitely be new lows among our usages of UNLEAK.
2) Use `pop_commit()` when looping. Slightly less simple change, but it
feels slightly preferable to first display the list, then free it.
3) As in this patch, but with `UNLEAK()` instead of freeing. We'd still
go through all the trouble of refactoring the loop, and because it's not
super-obvious that we're about to exit, let's just free the lists -- it
probably doesn't affect the runtime much.

In `handle_independent()` we can drop `result` while we're here and
reuse the `revs`-variable instead. That matches several other users of
`reduce_heads()`. The memory-leak that this hides will be addressed in
the next commit.

Ben Peart 00ec50e56d read_index_from(): speed index loading by skipping verification of the entry order
There is code in post_read_index_from() to catch out of order
entries when reading an index file.  This order verification is ~13%
of the cost of every call to read_index_from().

Update check_ce_order() so that it skips this verification unless
the "verify_ce_order" global variable is set.

Teach fsck to force this verification.

The effect can be seen using t/perf/p0002-read-cache.sh:

Martin Ågren 24d707f636 bisect: change calling-convention of find_bisection()
This function takes a commit list and returns a commit list. The
returned list is built by modifying the original list. Thus the caller
should not use the original list again (and after the next commit fixes
a memory leak, it must not).

Change the function signature so that it takes a **list and has void
return type. That should make it harder to misuse this function.

While we're here, document this function.

Martin Ågren 9560e6245a grep: take the read-lock when adding a submodule
With --recurse-submodules, we add each submodule that we encounter to
the list of alternate object databases. With threading, our changes to
the list are not protected against races. Indeed, ThreadSanitizer
reports a race when we call `add_to_alternates_memory()` around the same
time that another thread is reading in the list through
`read_sha1_file()`.

Take the grep read-lock while adding the submodule. The lock is used to
serialize uses of non-thread-safe parts of Git's API, including
`read_sha1_file()`.

Brandon Williams afa73c5384 diff: add flag to indicate textconv was set via cmdline
git-show is unique in that it wants to use textconv by default except
for when it is showing blobs.  When asked to show a blob, show doesn't
want to use textconv unless the user explicitly requested that it be
used by providing the command line flag '--textconv'.

Currently this is done by using a parallel set of 'touched' flags which
get set every time a particular flag is set or cleared.  In a future
patch we want to eliminate this parallel set of flags so instead of
relying on if the textconv flag has been touched, add a new flag
'TEXTCONV_SET_VIA_CMDLINE' which is only set if textconv is set to true
via the command line.

Jameson Miller eec0f7f2b7 status: add option to show ignored files differently
Teach the status command more flexibility in how ignored files are
reported. Currently, the reporting of ignored files and untracked
files are linked. You cannot control how ignored files are reported
independently of how untracked files are reported (i.e. `all` vs
`normal`). This makes it impossible to show untracked files with the
`all` option, but show ignored files with the `normal` option.

This work 1) adds the ability to control the reporting of ignored
files independently of untracked files and 2) introduces the concept
of status reporting ignored paths that explicitly match an ignored
pattern. There are 2 benefits to these changes: 1) if a consumer needs
all untracked files but not all ignored files, there is a performance
benefit to not scanning all contents of an ignored directory and 2)
returning ignored files that explicitly match a path allow a consumer
to make more informed decisions about when a status result might be
stale.

This commit implements --ignored=matching with --untracked-files=all.
The following commit will implement --ignored=matching with
--untracked=files=normal.

As an example of where this flexibility could be useful is that our
application (Visual Studio) runs the status command and presents the
output. It shows all untracked files individually (e.g. using the
'--untracked-files==all' option), and would like to know about which
paths are ignored. It uses information about ignored paths to make
decisions about when the status result might have changed.
Additionally, many projects place build output into directories inside
a repository's working directory (e.g. in "bin/" and "obj/"
directories). Normal usage is to explicitly ignore these 2 directory
names in the .gitignore file (rather than or in addition to the *.obj
pattern).If an application could know that these directories are
explicitly ignored, it could infer that all contents are ignored as
well and make better informed decisions about files in these
directories. It could infer that any changes under these paths would
not affect the output of status. Additionally, there can be a
significant performance benefit by avoiding scanning through ignored
directories.

When status is set to report matching ignored files, it has the
following behavior. Ignored files and directories that explicitly
match an exclude pattern are reported. If an ignored directory matches
an exclude pattern, then the path of the directory is returned. If a
directory does not match an exclude pattern, but all of its contents
are ignored, then the contained files are reported instead of the
directory.

Jeff King 752848df0f remote: handle broken symrefs
It's possible for resolve_ref_unsafe() to return NULL with a
REF_ISSYMREF flag if a symref points to a broken ref.  In
this case, the read_remote_branches() function will segfault
passing the name to xstrdup().

This is hard to trigger in practice, since this function is
used as a callback to for_each_ref(), which will skip broken
refs in the first place (so it would have to be broken
racily, or for us to see a transient filesystem error).

If we see such a racy broken outcome let's treat it as "not
a symref". This is exactly the same thing that would happen
in the non-racy case (our function would not be called at
all, as for_each_ref would skip the broken symref).

Jeff King b521fd1228 tag: respect color.ui config
Since 11b087adfd (ref-filter: consult want_color() before
emitting colors, 2017-07-13), we expect that setting
"color.ui" to "always" will enable color tag formats even
without a tty.  As that commit was built on top of
136c8c8b8f (color: check color.ui in git_default_config(),
2017-07-13) from the same series, we didn't need to touch
tag's config parsing at all.

However, since we reverted 136c8c8b8f, we now need to
explicitly call git_color_default_config() to make this
work.

Let's do so, and also restore the test dropped in 0c88bf5050
(provide --color option for all ref-filter users,
2017-10-03). That commit swapped out our "color.ui=always"
test for "--color" in preparation for "always" going away.
But since it is here to stay, we should test both cases.

Note that for-each-ref also lost its color.ui support as
part of reverting 136c8c8b8f. But as a plumbing command, it
should _not_ respect the color.ui config. Since it also
gained a --color option in 0c88bf5050, that's the correct
way to ask it for color. We'll continue to test that, and
confirm that "color.ui" is not respected.

Jeff King 33c643bb08 Revert "color: check color.ui in git_default_config()"
This reverts commit 136c8c8b8f.

That commit was trying to address a bug caused by 4c7f1819b3
(make color.ui default to 'auto', 2013-06-10), in which
plumbing like diff-tree defaulted to "auto" color, but did
not respect a "color.ui" directive to disable it.

But it also meant that we started respecting "color.ui" set
to "always". This was a known problem, but 4c7f1819b3 argued
that nobody ought to be doing that. However, that turned out
to be wrong, and we got a number of bug reports related to
"add -p" regressing in v2.14.2.

Let's revert 136c8c8b8, fixing the regression to "add -p".
This leaves the problem from 4c7f1819b3 unfixed, but:

  1. It's a pretty obscure problem in the first place. I
     only noticed it while working on the color code, and we
     haven't got a single bug report or complaint about it.

  2. We can make a more moderate fix on top by respecting
     "never" but not "always" for plumbing commands. This
     is just the minimal fix to go back to the working state
     we had before v2.14.2.

Note that this isn't a pure revert. We now have a test in
t3701 which shows off the "add -p" regression. This can be
flipped to success.

Brandon Williams aa9bab29b8 upload-pack, receive-pack: introduce protocol version 1
Teach upload-pack and receive-pack to understand and respond using
protocol version 1, if requested.

Protocol version 1 is simply the original and current protocol (what I'm
calling version 0) with the addition of a single packet line, which
precedes the ref advertisement, indicating the protocol version being
spoken.
