2721ce21e4 use string_list initializer consistently
There are two types of string_lists: those that own the
string memory, and those that don't. You can tell the
difference by the strdup_strings flag, and one should use
either STRING_LIST_INIT_DUP, or STRING_LIST_INIT_NODUP as an
initializer.

Historically, the normal all-zeros initialization has
corresponded to the NODUP case. Many sites use no
initializer at all, and that works as a shorthand for that
case. But for a reader of the code, it can be hard to
remember which is which. Let's be more explicit and actually
have each site declare which type it means to use.

This is a fairly mechanical conversion; I assumed each site
was correct as-is, and just switched them all to NODUP.

64093fc06a blame,shortlog: don't make local option variables static
There's no need for these option variables to be static,
except that they are referenced by the options array itself,
which is static. But having all of this static is simply
unnecessary and confusing (and inconsistent with most other
commands, which either use a static global option list or a
true function-local one).

Note that in some cases we may need to actually initialize
the variables (since we cannot rely on BSS to do so). This
is a net improvement to readability, though, as we can use
the more verbose initializers for our string_lists.

e51b0dfc97 builtin/commit.c: memoize git-path for COMMIT_EDITMSG
This is a follow up commit for f932729c (memoize common git-path
"constant" files, 10-Aug-2015).

The many function calls to git_path() are replaced by
git_path_commit_editmsg() and which thus eliminates the need to repeatedly
compute the location of "COMMIT_EDITMSG".

4e55ed32db add: add --chmod=+x / --chmod=-x options
The executable bit will not be detected (and therefore will not be
set) for paths in a repository with `core.filemode` set to false,
though the users may still wish to add files as executable for
compatibility with other users who _do_ have `core.filemode`
functionality.  For example, Windows users adding shell scripts may
wish to add them as executable for compatibility with users on
non-Windows.

Although this can be done with a plumbing command
(`git update-index --add --chmod=+x foo`), teaching the `git-add`
command allows users to set a file executable with a command that
they're already familiar with.

9f23e04061 pretty: support "mboxrd" output format
This output format prevents format-patch output from breaking
readers if somebody copy+pasted an mbox into a commit message.

Unlike the traditional "mboxo" format, "mboxrd" is designed to
be fully-reversible.  "mboxrd" also gracefully degrades to
showing extra ">" in existing "mboxo" readers.

This degradation is preferable to breaking message splitting
completely, a problem I've seen in "mboxcl" due to having
multiple, non-existent, or inaccurate Content-Length headers.

"mboxcl2" is a non-starter since it's inherits the problems
of "mboxcl" while being completely incompatible with existing
tooling based around mailsplit.

8f31fac365 builtin/apply: add 'lock_file' pointer into 'struct apply_state'
We cannot have a 'struct lock_file' allocated on the stack, as lockfile.c
keeps a linked list of all created lock_file structures.

Also 'struct apply_state' users might later want the same 'struct lock_file'
instance to be reused by different series of calls to the apply api.

So let's add a 'struct lock_file *lock_file' pointer into 'struct apply_state'
and have the user of 'struct apply_state' allocate memory for the actual
'struct lock_file' instance.

Let's also add an argument to init_apply_state(), so that the caller can
easily supply a pointer to the allocated instance.

fb85db84dc rev-list: disable bitmaps when "-n" is used with listing objects
You can ask rev-list to use bitmaps to speed up an --objects
traversal, which should generally give you your answers much
faster.

Likewise, you can ask rev-list to limit such a traversal
with `-n`, in which case we'll show only a limited set of
commits (and only the tree and commit objects directly
reachable from those commits).

But if you do both together, the results are nonsensical. We
end up limiting any fallback traversal we do to _find_ the
bitmaps, but the actual set of objects we output will be
picked arbitrarily from the union of any bitmaps we do find,
and will involve the objects of many more commits.

It's possible that somebody might want this as a "show me
what you can, but limit the amount of work you do" flag.
But as with the prior commit clamping "--count", the results
are basically non-deterministic; you'll get the values from
some commits between `n` and the total number, and you can't
tell which.

And unlike the `--count` case, we can't easily generate the
"real" value from the bitmap values (you can't just walk
back `-n` commits and subtract out the reachable objects
from the boundary commits; the bitmaps for `X` record its
total reachability, so you don't know which objects are
directly from `X` itself, which from `X^`, and so on).

So let's just fallback to the non-bitmap code path in this
case, so we always give a sane answer.

5c9f9bf313 rev-list: "adjust" results of "--count --use-bitmap-index -n"
If you ask rev-list for:

    git rev-list --count --use-bitmap-index HEAD

we optimize out the actual traversal and just give you the
number of bits set in the commit bitmap. This is faster,
which is good.

But if you ask to limit the size of the traversal, like:

    git rev-list --count --use-bitmap-index -n 100 HEAD

we'll still output the full bitmapped number we found. On
the surface, that might even seem OK. You explicitly asked
to use the bitmap index, and it was cheap to compute the
real answer, so we gave it to you.

But there's something much more complicated going on under
the hood. If we don't have a bitmap directly for HEAD, then
we have to actually traverse backwards, looking for a
bitmapped commit. And _that_ traversal is bounded by our
`-n` count.

This is a good thing, because it bounds the work we have to
do, which is probably what the user wanted by asking for
`-n`. But now it makes the output quite confusing. You might
get many values:

  - your `-n` value, if we walked back and never found a
    bitmap (or fewer if there weren't that many commits)

  - the actual full count, if we found a bitmap root for
    every path of our traversal with in the `-n` limit

  - any number in between! We might have walked back and
    found _some_ bitmaps, but then cut off the traversal
    early with some commits not accounted for in the result.

So you cannot even see a value higher than your `-n` and say
"OK, bitmaps kicked in, this must be the real full count".
The only sane thing is for git to just clamp the value to a
maximum of the `-n` value, which means we should output the
exact same results whether bitmaps are in use or not.

The test in t5310 demonstrates this by using `-n 1`.
Without this patch we fail in the full-bitmap case (where we
do not have to traverse at all) but _not_ in the
partial-bitmap case (where we have to walk down to find an
actual bitmap). With this patch, both cases just work.

I didn't implement the crazy in-between case, just because
it's complicated to set up, and is really a subset of the
full-count case, which we do cover.

"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag.  It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge.  The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit

c57e501c51 pull: warn on --verify-signatures with --rebase
git-pull silently ignores the --verify-signatures option when
running --rebase, potentially leaving users in the belief that
the rebase operation would check for valid GPG signatures.

Implementing --verify-signatures for git-rebase was talked about,
but doubts for a valid workflow rose up.  Since you usually merge
other's branches into your branch you might have an interest that
their side has a valid GPG signature.

Rebasing, on the other hand, is to rebuild your branch on top of
other's work, in order to push the result back, and it is too late
to reject their work even if you find their commits lack acceptable
signature.

Let's warn users that the --verify-signatures option is ignored
during "pull --rebase"; users do not wonder what would happen if
their commits lack acceptable signature that way.

6a36e1e7bb cat-file: default to --buffer when --batch-all-objects is used
Traditionally cat-file's batch-mode does not do any output
buffering. The reason is that a caller may have pipes
connected to its input and output, and would want to use
cat-file interactively, getting output immediately for each
input it sends.

This may involve a lot of small write() calls, which can be
slow. So we introduced --buffer to improve this, but we
can't turn it on by default, as it would break the
interactive case above.

However, when --batch-all-objects is used, we do not read
stdin at all. We generate the output ourselves as quickly as
possible, and then exit. In this case buffering is a strict
win, and it is simply a hassle for the user to have to
remember to specify --buffer.

This patch makes --buffer the default when --batch-all-objects
is used. Specifying "--buffer" manually is still OK, and you
can even override it with "--no-buffer" if you're a
masochist (or debugging).

For some real numbers, running:

  git cat-file --batch-all-objects --batch-check='%(objectname)'

on torvalds/linux goes from:

  real    0m1.464s
  user    0m1.208s
  sys     0m0.252s

to:

  real    0m1.230s
  user    0m1.172s
  sys     0m0.056s

for a 16% speedup.

845de33a5b cat-file: avoid noop calls to sha1_object_info_extended

  1. With --batch-all-objects, you can generate a listing of
     the sha1s present in the repository, without any input.

  2. You do not have to feed sha1s; you can feed arbitrary
     sha1 expressions and have git resolve them en masse.

  3. You can even feed a raw sha1, with the result that git
     will tell you whether we actually have the object or
     not.

In case 3, the call to sha1_object_info is useful; it tells
us whether the object exists or not (technically we could
swap this out for has_sha1_file, but the cost is roughly the
same).

In case 2, the existence check is of debatable value. A
mass-resolution might prefer performance to safety (against
outputting a value for a corrupted ref, for example).
However, the object lookup cost is likely not as noticeable
compared to the resolution cost. And since we have provided
that safety in the past, the conservative choice is to keep
it.

In case 1, though, the object lookup is a definite noop; we
know about the object because we found it in the object
database. There is no new information gained by making the
call.

This patch detects that case and optimizes out the call.
Here are best-of-five timings for linux.git:

  [before]
  $ time git cat-file --buffer \
                      --batch-all-objects \
                      --batch-check='%(objectname)'
  real    0m2.117s
  user    0m2.044s
  sys     0m0.072s

  [after]
  $ time git cat-file --buffer \
                      --batch-all-objects \
                      --batch-check='%(objectname)'
  real    0m1.230s
  user    0m1.176s
  sys     0m0.052s

There are two implementation details to note here.

One is that we detect the noop case by seeing that "struct
object_info" does not request any information. But besides
object existence, there is one other piece of information
which sha1_object_info may fill in: whether the object is
cached, loose, or packed. We don't currently provide that
information in the output, but if we were to do so later,
we'd need to take note and disable the optimization in that
case.

And that leads to the second note. If we were to output
that information, a better implementation would be to
remember where we saw the object in --batch-all-objects in
the first place, and avoid looking it up again by sha1.

In fact, we could probably squeeze out some extra
performance for less-trivial cases, too, by remembering the
pack location where we saw the object, and going directly
there to find its information (like type, size, etc). That
would in theory make this optimization unnecessary.

I didn't pursue that path here for two reasons:

  1. It's non-trivial to implement, and has memory
     implications. Because we sort and de-dup the list of
     output sha1s, we'd have to record the pack information
     for each object, too.

  2. It doesn't save as much as you might hope. It saves the
     find_pack_entry() call, but getting the size and type
     for deltified objects requires walking down the delta
     chain (for the real type) or reading the delta data
     header (for the size). These costs tend to dominate the
     non-trivial cases.

By contrast, this optimization is easy and self-contained,
and speeds up a real-world case I've used.

90a78b83e0 diff: run arguments through precompose_argv
When running diff commands, a pathspec containing decomposed
unicode code points is not converted to precomposed unicode form
under Mac OS X, but we normalize the paths in the index and the
history to precomposed form on that platform.  As a result, the
pathspec would not match and no diff is shown.

Unlike many builtin commands, the "diff" family of commands do
not use parse_options(), which is how other builtin commands
indirectly call precompose_argv() to normalize argv[] into
precomposed form on Mac OSX.  Teach these commands to call
precompose_argv() themselves.

Note that precomopose_argv() normalizes not just paths but all
command line arguments, so things like "git diff -G $string"
when $string has the decomposed form would first be normalized
into the precomposed form and would stop hitting the same string
in the decomposed form in the diff output with this change.

It is not a problem per-se, as "log" family of commands already use
parse_options() and call precompose_argv()--we can think of this
change as making the "diff" family of commands behave in a similar
way as the commands in the "log" family.

2fc0f1849b builtin/apply: introduce 'struct apply_state' to start libifying
Currently commands that want to use the apply functionality have to launch
a "git apply" process which can be bad for performance.

Let's start libifying the apply functionality and to do that we first need
to get rid of the global variables in "builtin/apply.c".

This patch introduces "struct apply_state" into which all the previously
global variables will be moved. A new parameter called "state" that is a
pointer to the "apply_state" structure will come at the beginning of the
helper functions that need it and will be passed around the call chain.

To start let's move the "prefix" and "prefix_length" global variables into
"struct apply_state".

89044baa8b submodule: stop sanitizing config options
The point of having a whitelist of command-line config
options to pass to submodules was two-fold:

  1. It prevented obvious nonsense like using core.worktree
     for multiple repos.

  2. It could prevent surprise when the user did not mean
     for the options to leak to the submodules (e.g.,
     http.sslverify=false).

For case 1, the answer is mostly "if it hurts, don't do
that". For case 2, we can note that any such example has a
matching inverted surprise (e.g., a user who meant
http.sslverify=true to apply everywhere, but it didn't).

So this whitelist is probably not giving us any benefit, and
is already creating a hassle as people propose things to put
on it. Let's just drop it entirely.

Note that we still need to keep a special code path for
"prepare the submodule environment", because we still have
to take care to pass through $GIT_CONFIG_PARAMETERS (and
block the rest of the repo-specific environment variables).

We can do this easily from within the submodule shell
script, which lets us drop the submodule--helper option
entirely (and it's OK to do so because as a "--" program, it
is entirely a private implementation detail).

described with respect to an old tag but with a newer tag.  It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge.  The logic has been

is a lot easier to explain to the end users: "We describe a commit

6694856153 commit-tree: do not pay attention to commit.gpgsign
ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) introduced a
"signed commit" by teaching the --[no]-gpg-sign option and the
commit.gpgsign configuration variable to various commands that
create commits.

Teaching these to "git commit" and "git merge", both of which are
end-user facing Porcelain commands, was perfectly fine.  Allowing
the plumbing "git commit-tree" to suddenly change the behaviour to
surprise the scripts by paying attention to commit.gpgsign was not.

Among the in-tree scripts, filter-branch, quiltimport, rebase and
stash are the commands that run "commit-tree".  If any of these
wants to allow users to always sign every single commit, they should
offer their own configuration (e.g. "filterBranch.gpgsign") with an
option to disable signing (e.g. "git filter-branch --no-gpgsign").

Ignoring commit.gpgsign option _obviously_ breaks the backward
compatibility, but it is easy to follow the standard pattern in
scripts to honor whatever configuration variable they choose to
follow.  E.g.

	case $(git config --bool commit.gpgsign) in
	true) sign=-S ;;
	*) sign= ;;

c66410ed32 submodule init: redirect stdout to stderr
Reroute the output of stdout to stderr as it is just informative
messages, not to be consumed by machines.

This should not regress any scripts that try to parse the
current output, as the output is already internationalized
and therefore unstable.

We want to init submodules from the helper for `submodule update`
in a later patch and the stdout output of said helper is consumed
by the parts of `submodule update` which are still written in shell.
So we have to be careful which messages are on stdout.

fa2ab86d18 format-patch: add '--base' option to record base tree info
Maintainers or third party testers may want to know the exact base tree
the patch series applies to. Teach git format-patch a '--base' option
to record the base tree info and append it at the end of the first
message (either the cover letter or the first patch in the series).

The base tree info consists of the "base commit", which is a well-known
commit that is part of the stable part of the project history everybody
else works off of, and zero or more "prerequisite patches", which are
well-known patches in flight that is not yet part of the "base commit"
that need to be applied on top of "base commit" in topological order
before the patches can be applied.

The "base commit" is shown as "base-commit: " followed by the 40-hex of
the commit object name.  A "prerequisite patch" is shown as
"prerequisite-patch-id: " followed by the 40-hex "patch id", which can
be obtained by passing the patch through the "git patch-id --stable"
command.

Imagine that on top of the public commit P, you applied well-known
patches X, Y and Z from somebody else, and then built your three-patch
series A, B, C, the history would be like:

---P---X---Y---Z---A---B---C

With "git format-patch --base=P -3 C" (or variants thereof, e.g. with
"--cover-letter" of using "Z..C" instead of "-3 C" to specify the
range), the base tree information block is shown at the end of the
first message the command outputs (either the first patch, or the
cover letter), like this:

base-commit: P
prerequisite-patch-id: X
prerequisite-patch-id: Y
prerequisite-patch-id: Z

d22eb04475 clone: add --shallow-submodules flag
When creating a shallow clone of a repository with submodules, the depth
argument does not influence the submodules, i.e. the submodules are done
as non-shallow clones. It is unclear what the best default is for the
depth of submodules of a shallow clone, so we need to have the possibility
to do all kinds of combinations:

* shallow super project with shallow submodules
  e.g. build bots starting always from scratch. They want to transmit
  the least amount of network data as well as using the least amount
  of space on their hard drive.
* shallow super project with unshallow submodules
  e.g. The superproject is just there to track a collection of repositories
  and it is not important to have the relationship between the repositories
  intact. However the history of the individual submodules matter.
* unshallow super project with shallow submodules
  e.g. The superproject is the actual project and the submodule is a
  library which is rarely touched.

The new switch to select submodules to be shallow or unshallow supports
all of these three cases.

It is easy to transition from the first to the second case by just
unshallowing the submodules (`git submodule foreach git fetch
--unshallow`), but it is not possible to transition from the second to the
first case (as we would have already transmitted the non shallow over
the network). That is why we want to make the first case the default in
case of a shallow super project. This leads to the inconvenience in the
second case with the shallow super project and unshallow submodules,
as you need to pass `--no-shallow-submodules`.

14ace5b77b branch: do not rename a branch under bisect or rebase
The branch name in that case could be saved in rebase's head_name or
bisect's BISECT_START files. Ideally we should try to update them as
well. But it's trickier (*). Let's play safe and see if the user
complains about inconveniences before doing that.

(*) If we do it, bisect and rebase need to provide an API to rename
branches. We can't do it in worktree.c or builtin/branch.c because
when other people change rebase/bisect code, they may not be aware of
this code and accidentally break it (e.g. rename the branch file, or
refer to the branch in new files). It's a lot more work.

8d9fdd7087 worktree.c: check whether branch is rebased in another worktree
This function find_shared_symref() is used in a couple places:

1) in builtin/branch.c: it's used to detect if a branch is checked out
   elsewhere and refuse to delete the branch.

2) in builtin/notes.c: it's used to detect if a note is being merged in
   another worktree

3) in branch.c, the function die_if_checked_out() is actually used by
   "git checkout" and "git worktree add" to see if a branch is already
   checked out elsewhere and refuse the operation.

In cases 1 and 3, if a rebase is ongoing, "HEAD" will be in detached
mode, find_shared_symref() fails to detect it and declares "no branch is
checked out here", which is not really what we want.

This patch tightens the test. If the given symref is "HEAD", we try to
detect if rebase is ongoing. If so return the branch being rebased. This
makes checkout and branch delete operations safer because you can't
checkout a branch being rebased in another place, or delete it.

Special case for checkout. If the current branch is being rebased,
git-rebase.sh may use "git checkout" to abort and return back to the
original branch. The updated test in find_shared_symref() will prevent
that and "git rebase --abort" will fail as a result.
find_shared_symref() and die_if_checked_out() have to learn a new
option ignore_current_worktree to loosen the test a bit.

78ccd44195 verify-tag: prepare verify_tag for libification
The current interface of verify_tag() resolves reference names to SHA1,
however, the plan is to make this functionality public and the current
interface is cumbersome for callers: they are expected to supply the
textual representation of a sha1/refname. In many cases, this requires
them to turn the sha1 to hex representation, just to be converted back
inside verify_tag.

Add a SHA1 parameter to use instead of the name parameter, and rename
the name parameter to "name_to_report" for reporting purposes only.

We most likely want the oldest tag that contained the commit to be

than anything else when choosing the best name for a given commit.

Suggested by Linus Torvalds.

Note that we need to update t9903 because it tested for the old behavior
(which preferred the description "b1~1" over "tags/t2~1").

We might want to introduce a --heed-taggerdate option, and make the new
behavior dependent on that, if it turns out that some scripts rely on the
old name-rev method.

    because such a "two project merge" would be done after fetching
    the other project into some location in the working tree of an

    is sufficient to allow a local merge without such an option

a127331cd8 mv: allow moving nested submodules
When directories are moved using `git mv` all files in the directory
have been just moved, but no further action was taken on them. This
was done by assigning the mode = WORKING_DIRECTORY to the files
inside a moved directory.

submodules however need to update their link to the git directory as
well as updates to the .gitmodules file. By removing the condition of
`mode != INDEX` (the remaining modes are BOTH and WORKING_DIRECTORY) for
the required submodule actions, we perform these for submodules in a
moved directory.

3604242f08 submodule: port init from shell to C
By having the `submodule init` functionality in C, we can reference it
easier from other parts in the code in later patches. The code is split
up to have one function to initialize one submodule and a calling function
that takes care of the rest, such as argument handling and translating the
arguments to the paths of the submodules.

This is the first submodule subcommand that is fully converted to C
except for the usage string, so this is actually removing a call to
the `submodule--helper list` function, which is supposed to be used in
this transition. Instead we'll make a direct call to `module_list_compute`.

An explanation why we need to edit the prefixes in cmd_update in
git-submodule.sh in this patch:

By having no processing in the shell part, we need to convey the notion
of wt_prefix and prefix to the C parts, which former patches punted on
and did the processing of displaying path in the shell.

`wt_prefix` used to hold the path from the repository root to the current
directory, e.g. wt_prefix would be t/ if the user invoked the
`git submodule` command in ~/repo/t and ~repo is the GIT_DIR.

`prefix` used to hold the relative path from the repository root to the
operation, e.g. if you have recursive submodules, the shell script would
modify the `prefix` in each recursive step by adding the submodule path.

We will pass `wt_prefix` into the C helper via `git -C <dir>` as that
will setup git in the directory the user actually called git-submodule.sh
from. The `prefix` will be passed in via the `--prefix` option.

Having `prefix` and `wt_prefix` relative to the GIT_DIR of the
calling superproject is unfortunate with this patch as the C code doesn't
know about a possible recursion from a superproject via `submodule update
--init --recursive`.

To fix this, we change the meaning of `wt_prefix` to point to the current
project instead of the superproject and `prefix` to include any relative
paths issues in the superproject. That way `prefix` will become the leading
part for displaying paths and `wt_prefix` will be empty in recursive
calls for now.

The new notion of `wt_prefix` and `prefix` still allows us to reconstruct
the calling directory in the superproject by just traveling reverse of
`prefix`.

63e95beb08 submodule: port resolve_relative_url from shell to C
Later on we want to automatically call `git submodule init` from
other commands, such that the users don't have to initialize the
submodule themselves.  As these other commands are written in C
already, we'd need the init functionality in C, too.  The
`resolve_relative_url` function is a large part of that init
functionality, so start by porting this function to C.

To create the tests in t0060, the function `resolve_relative_url`
was temporarily enhanced to write all inputs and output to disk
when running the test suite. The added tests in this patch are
a small selection thereof.

40d71940b6 builtin/merge.c: fix a bug with trivial merges
If read_tree_trivial() succeeds and produces a tree that is already
in the object store, then the index is not written to disk, leaving
it out-of-sync with both HEAD and the working tree.

In order to write the index back out to disk after a merge,
write_index_locked() needs to be called.  For most merge strategies, this
is done from try_merge_strategy().  For fast forward updates, this is
done from checkout_fast_forward().  When trivial merges work, the call to
write_index_locked() is buried a little deeper:

  merge_trivial()
  -> write_tree_trivial()
     -> write_cache_as_tree()
        -> write_index_as_tree()
           -> write_locked_index()

However, it is only called when !cache_tree_fully_valid(), which is how
this bug is triggered.  But that also shows why this bug doesn't affect
any other merge strategies or cases.

Add a direct call to write_index_locked() from merge_trivial() to fix
this issue.  Since the indirect call to write_locked_index() was
conditional on cache_tree_fully_valid(), it won't be written twice.

When f9568530 (builtin-commit: resurrect behavior for multiple -m
options, 2007-11-11) converted a "char *message" to "struct strbuf
message" to hold the messages given with the "-m" option, it
incorrectly changed the checks "did we get a message with the -m
option?" to "is message.len 0?".  Later, we noticed one breakage
from this change and corrected it with 25206778 (commit: don't start
editor if empty message is given with -m, 2013-05-25).

However, "we got a message with -m, even though an empty one, so we
shouldn't be launching an editor" was not the only breakage.

 * "git commit --amend -m '' --allow-empty", even though it looks
   strange, is a valid request to amend the commit to have no
   message at all.  Due to the misdetection of the presence of -m on
   the command line, we ended up keeping the log messsage from the
   original commit.

 * "git commit -m "$msg" -F file" should be rejected whether $msg is
   an empty string or not, but due to the same bug, was not rejected
   when $msg is empty.

 * "git -c template=file -m "$msg"" should ignore the template even
   when $msg is empty, but it didn't and instead used the contents
   from the template file.

Correct these by checking have_option_m, which the earlier 25206778
introduced to fix the same bug.

d281b45d75 builtin/verify-tag.c: ignore SIGPIPE in gpg-interface
The verify_signed_buffer() function may trigger a SIGPIPE when the
GPG child process terminates early (due to a bad keyid, for example)
and Git tries to write to it afterwards.  Previously, ignoring
SIGPIPE was done in builtin/verify-tag.c to avoid this issue.

However, any other caller who wants to call verify_signed_buffer()
would have to do the same.

Use sigchain_push(SIGPIPE, SIG_IGN) in verify_signed_buffer(),
pretty much like in sign_buffer(), so that any caller is not
required to perform this task.

This will avoid possible mistakes by further developers using
verify_signed_buffer().

a08feb8ef0 correct blame for files commited with CRLF
git blame reports lines as not "Not Committed Yet" when they have
CRLF in the index, CRLF in the worktree and core.autocrlf is true.

Since commit c4805393 (autocrlf: Make it work also for un-normalized
repositories, 2010-05-12), files that have CRLF in the index are not
normalized at commit when core.autocrl is set.

Add a call to read_cache() early in fake_working_tree_commit(),

95c38fb0ed branch: fix shortening of non-remote symrefs
Commit aedcb7d (branch.c: use 'ref-filter' APIs, 2015-09-23)
adjusted the symref-printing code to look like this:

    if (item->symref) {
	    skip_prefix(item->symref, "refs/remotes/", &desc);
	    strbuf_addf(&out, " -> %s", desc);
    }

This has three bugs in it:

  1. It always skips past "refs/remotes/", instead of
     skipping past the prefix associated with the branch we
     are showing (so commonly we see "refs/remotes/" for the
     refs/remotes/origin/HEAD symref, but the previous code
     would skip "refs/heads/" when showing a symref it found
     in refs/heads/.

  2. If skip_prefix() does not match, it leaves "desc"
     untouched, and we show whatever happened to be in it
     (which is the refname from a call to skip_prefix()
     earlier in the function).

  3. If we do match with skip_prefix(), we stomp on the
     "desc" variable, which is later passed to
     add_verbose_info(). We probably want to retain the
     original refname there (though it likely doesn't matter
     in practice, since after all, one points to the other).

The fix to match the original code is fairly easy: record
the prefix to strip based on item->kind, and use it here.
However, since we already have a local variable named "prefix",
let's give the two prefixes verbose names so we don't
confuse them.

70999e9cec branch -m: update all per-worktree HEADs
When renaming a branch, currently only the HEAD of current working tree

the old branch.

This is the current behavior, /path/to/wt's HEAD is not updated:

  % git worktree list
  /path/to     2c3c5f2 [master]
  /path/to/wt  2c3c5f2 [oldname]
  % git branch -m master master2
  % git worktree list

  % git branch -m oldname newname
  % git worktree list
  /path/to     2c3c5f2 [master2]

1ea4d9b7c8 submodule--helper: do not borrow absolute_path() result for too long
absolute_path() is designed to allow its callers to take a brief
peek of the result (typically, to be fed to functions like
strbuf_add() and relative_path() as a parameter) without having to
worry about freeing it, but the other side of the coin of that
memory model is that the caller shouldn't rely too much on the
result living forever--there may be a helper function the caller
subsequently calls that makes its own call to absolute_path(),
invalidating the earlier result.

Use xstrdup() to make our own copy, and free(3) it when we are done.

so parse_binary() can return -1, because that's what error() returns.

Also parse_binary_hunk() sets "status" to -1 in case of error and
parse_binary() does "if (status) return status;".

In this case parse_chunk() should not add -1 to the patchsize it computes.

c6777563cd git-send-pack: fix --all option when used with directory
When using git send-pack with --all option
and a target repository specification ([<host>:]<directory>),
usage message is being displayed instead of performing
the actual transmission.

The reason for this issue is that destination and refspecs are being set
in the same conditional and are populated from argv. When a target
repository is passed, refspecs is being populated as well with its value.
This makes the check for refspecs not being NULL to always return true,
which, in conjunction with the check for --all or --mirror options,
is always true as well and returns usage message instead of proceeding.

This ensures that send-pack will stop execution only when --all
or --mirror switch is used in conjunction with any refspecs passed.

e379fdf34f merge: refuse to create too cool a merge by default
While it makes sense to allow merging unrelated histories of two
projects that started independently into one, in the way "gitk" was
merged to "git" itself aka "the coolest merge ever", such a merge is
still an unusual event.	 Worse, if somebody creates an independent
history by starting from a tarball of an established project and
sends a pull request to the original project, "git merge" however
happily creates such a merge without any sign of something unusual
is happening.

Teach "git merge" to refuse to create such a merge by default,
unless the user passes a new "--allow-unrelated-histories" option to
tell it that the user is aware that two unrelated projects are
merged.

Because such a "two project merge" is a rare event, a configuration
option to always allow such a merge is not added.

We could add the same option to "git pull" and have it passed
through to underlying "git merge".  I do not have a fundamental
opposition against such a feature, but this commit does not do so
and instead leaves it as low-hanging fruit for others, because such
a "two project merge" would be done after fetching the other project
into some location in the working tree of an existing project and
making sure how well they fit together, it is sufficient to allow a
local merge without such an option pass-through from "git pull" to
"git merge".  Many tests that are updated by this patch does the
pass-through manually by turning:

	git pull something

into its equivalent:

	git fetch something &&
	git merge --allow-unrelated-histories FETCH_HEAD

If somebody is inclined to add such an option, updated tests in this
change need to be adjusted back to:

	git pull --allow-unrelated-histories something

This regression was introduced in 74703a1e4d (submodule: rewrite
`module_list` shell function in C, 2015-09-02), as we changed the
order of checking in new module listing to first check whether it is
a gitlin before feeding it to match_pathspec().  It used to be that
a pathspec that does not match any path were diagnosed as an error,
but the new code complains for a pathspec that does not match any
submodule path.

Arguably the new behaviour may give us a better diagnosis, but that
is inconsistent with the suggestion "deinit" gives, and also this
was an unintended accident.  The new behaviour hopefully can be
redesigned and implemented better in future releases, but for now,
switch these two checks to restore the same behavior as before.  In
an empty repository, giving the pathspec '.' will still get the same
"did not match" error, but that is the same bug we had before 1.7.0.

2824e1841b list-objects: pass full pathname to callbacks
When we find a blob at "a/b/c", we currently pass this to
our show_object_fn callbacks as two components: "a/b/" and
"c". Callbacks which want the full value then call
path_name(), which concatenates the two. But this is an
inefficient interface; the path is a strbuf, and we could
simply append "c" to it temporarily, then roll back the
length, without creating a new copy.

So we could improve this by teaching the callsites of
path_name() this trick (and there are only 3). But we can
also notice that no callback actually cares about the
broken-down representation, and simply pass each callback
the full path "a/b/c" as a string. The callback code becomes
even simpler, then, as we do not have to worry about freeing
an allocated buffer, nor rolling back our modification to
the strbuf.

This is theoretically less efficient, as some callbacks
would not bother to format the final path component. But in
practice this is not measurable. Since we use the same
strbuf over and over, our work to grow it is amortized, and
we really only pay to memcpy a few bytes.

dc06dc8800 list-objects: drop name_path entirely
In the previous commit, we left name_path as a thin wrapper
around a strbuf. This patch drops it entirely. As a result,
every show_object_fn callback needs to be adjusted. However,
none of their code needs to be changed at all, because the
only use was to pass it to path_name(), which now handles
the bare strbuf.

85975c0c7f grep: turn off gitlink detection for --no-index
If we are running "git grep --no-index" outside of a git
repository, we behave roughly like "grep -r", examining all
files in the current directory and its subdirectories.
However, because we use fill_directory() to do the
recursion, it will skip over any directories which look like
sub-repositories.

For a normal git operation (like "git grep" in a repository)
this makes sense; we do not want to cross the boundary out
of our current repository into a submodule. But for
"--no-index" without a repository, we should look at all
files, including embedded repositories.

There is one exception, though: we probably should _not_
descend into ".git" directories. Doing so is inefficient and
unlikely to turn up useful hits.

This patch drops our use of dir.c's gitlink-detection, but
we do still avoid ".git". That makes us more like tools such
as "ack" or "ag", which also know to avoid cruft in .git.

As a bonus, this also drops our usage of the ref code
when we are outside of a repository, making the transition
to pluggable ref backends cleaner.

f1c126bd8b setup: set startup_info->have_repository more reliably
When setup_git_directory() is called, we set a flag in
startup_info to indicate we have a repository. But there are
a few other mechanisms by which we might set up a repo:

  1. When creating a new repository via init_db(), we
     transition from no-repo to being in a repo. We should
     tweak this flag at that moment.

  2. In enter_repo(), a stricter form of
     setup_git_directory() used by server-side programs, we
     check the repository format config. After doing so, we
     know we're in a repository, and can set the flag.

With these changes, library code can now reliably tell
whether we are in a repository and act accordingly. We'll
leave the "prefix" field as NULL, which is what happens when
setup_git_directory() finds there is no prefix.

As we create the .keep file with O_CREAT|O_EXCL, and we do so after
we write the .idx file, we luckily do not clobber the .idx file, but
because we deliberately ignored EEXIST when creating .keep file
(which is justifiable because only the existence of .keep file
matters), nobody noticed this mistake so far.

14111fc492 git: submodule honor -c credential.* from command line
Due to the way that the git-submodule code works, it clears all local
git environment variables before entering submodules. This is normally
a good thing since we want to clear settings such as GIT_WORKTREE and
other variables which would affect the operation of submodule commands.
However, GIT_CONFIG_PARAMETERS is special, and we actually do want to
preserve these settings. However, we do not want to preserve all
configuration as many things should be left specific to the parent
project.

Add a git submodule--helper function, sanitize-config, which shall be
used to sanitize GIT_CONFIG_PARAMETERS, removing all key/value pairs
except a small subset that are known to be safe and necessary.

Replace all the calls to clear_local_git_env with a wrapped function
that filters GIT_CONFIG_PARAMETERS using the new helper and then
restores it to the filtered subset after clearing the rest of the
environment.

fc7d47f0dd rev-parse: let some options run outside repository
Once upon a time, you could use "--local-env-vars" and
"--resolve-git-dir" outside of any git repository, but they
had to come first on the command line. Commit 68889b4
(rev-parse: remove restrictions on some options, 2013-07-21)
put them into the normal option-parsing loop, fixing the
latter. But it inadvertently broke the former, as we call
setup_git_directory() before starting that loop.

We can note that those options don't care even conditionally
about whether we are in a git repo. So it's fine if we
simply wait to setup the repo until we see an option that
needs it.

However, there is one special exception we should make:
historically, rev-parse will set up the repository and read
config even if there are _no_ options. Some of the
tests in t1300 rely on this to check "git -c $config"
parsing. That's not mirroring real-world use, and we could
tweak the test.  But t0002 uses a bare "git rev-parse" to
check "are we in a git repository?". It's plausible that
real-world scripts are relying on this.

So let's cover this case specially, and treat an option-less
"rev-parse" as "see if we're in a repo".

47fe3f6ef0 nth_packed_object_offset: bounds-check extended offset
If a pack .idx file has a corrupted offset for an object, we
may try to access an offset in the .idx or .pack file that
is larger than the file's size.  For the .pack case, we have
use_pack() to protect us, which realizes the access is out
of bounds. But if the corrupted value asks us to look in the
.idx file's secondary 64-bit offset table, we blindly add it
to the mmap'd index data and access arbitrary memory.

We can fix this with a simple bounds-check compared to the
size we found when we opened the .idx file.

Note that there's similar code in index-pack that is
triggered only during "index-pack --verify". To support
both, we pull the bounds-check into a separate function,
which dies when it sees a corrupted file.

It would be nice if we could return an error, so that the
pack code could try to find a good copy of the object
elsewhere. Currently nth_packed_object_offset doesn't have
any way to return an error, but it could probably use "0" as
a sentinel value (since no object can start there). This is
the minimal fix, and we can improve the resilience later on
top.

5404c116aa diff: activate diff.renames by default
Rename detection is a very convenient feature, and new users shouldn't
have to dig in the documentation to benefit from it.

Potential objections to activating rename detection are that it
sometimes fail, and it is sometimes slow. But rename detection is
already activated by default in several cases like "git status" and "git
merge", so activating diff.renames does not fundamentally change the
situation. When the rename detection fails, it now fails consistently
between "git diff" and "git status".

This setting does not affect plumbing commands, hence well-written
scripts will not be affected.

2f275207ce push: remove "push.default is unset" warning message
The warning was important before the 2.0 transition, and remained
important for a while after, so that new users get push.default
explicitly in their configuration and do not experience inconsistent
behavior if they ever used an older version of Git.

The warning has been there since version 1.8.0 (Oct 2012), hence we can
expect the vast majority of current Git users to have been exposed to
it, and most of them have already set push.default explicitly. The
switch from 'matching' to 'simple' was planned for 2.0 (May 2014), but
actually happened only for 2.3 (Feb 2015).

Today, the warning is mostly seen by beginners, who have not set their
push.default configuration (yet). For many of them, the warning is
confusing because it talks about concepts that they have not learned and
asks them a choice that they are not able to make yet. See for example

  http://stackoverflow.com/questions/13148066/warning-push-default-is-unset-its-implicit-value-is-changing-in-git-2-0

(1260 votes for the question, 1824 for the answer as of writing)

Remove the warning completely to avoid disturbing beginners. People who
still occasionally use an older version of Git will be exposed to the
warning through this old version.

Eventually, versions of Git without the warning will be deployed enough
and tutorials will not need to advise setting push.default anymore.

5545f057d4 fetch-pack: simplify add_sought_entry
We have two variants of this function, one that takes a
string and one that takes a ptr/len combo. But we only call
the latter with the length of a NUL-terminated string, so
our first simplification is to drop it in favor of the
string variant.

Since we know we have a string, we can also replace the
manual memory computation with a call to alloc_ref().

Furthermore, we can rely on get_oid_hex() to complain if it
hits the end of the string. That means we can simplify the
check for "<sha1> <ref>" versus just "<ref>". Rather than
manage the ptr/len pair, we can just bump the start of our
string forward. The original code over-allocated based on
the original "namelen" (which wasn't _wrong_, but was simply
wasteful and confusing).

3733e69464 use xmallocz to avoid size arithmetic
We frequently allocate strings as xmalloc(len + 1), where
the extra 1 is for the NUL terminator. This can be done more
simply with xmallocz, which also checks for integer
overflow.

There's no case where switching xmalloc(n+1) to xmallocz(n)
is wrong; the result is the same length, and malloc made no
guarantees about what was in the buffer anyway. But in some
cases, we can stop manually placing NUL at the end of the
allocated buffer. But that's only safe if it's clear that
the contents will always fill the buffer.

In each case where this patch does so, I manually examined
the control flow, and I tried to err on the side of caution.

850d2fec53 convert manual allocations to argv_array
There are many manual argv allocations that predate the
argv_array API. Switching to that API brings a few
advantages:

  1. We no longer have to manually compute the correct final
     array size (so it's one less thing we can screw up).

  2. In many cases we had to make a separate pass to count,
     then allocate, then fill in the array. Now we can do it
     in one pass, making the code shorter and easier to
     follow.

  3. argv_array handles memory ownership for us, making it
     more obvious when things should be free()d and and when
     not.

Most of these cases are pretty straightforward. In some, we
switch from "run_command_v" to "run_command" which lets us
directly use the argv_array embedded in "struct
child_process".

c3a700fba1 reflog_expire_cfg: NUL-terminate pattern field
You can tweak the reflog expiration for a particular subset
of refs by configuring gc.foo.reflogexpire. We keep a linked
list of reflog_expire_cfg structs, each of which holds the
pattern and a "len" field for the length of the pattern. The
pattern itself is _not_ NUL-terminated.

However, we feed the pattern directly to wildmatch(), which
expects a NUL-terminated string, meaning it may keep reading
random junk after our struct.

We can fix this by allocating an extra byte for the NUL
(which is already zero because we use xcalloc). Let's also
drop the misleading "len" field, which is no longer
necessary. The existing use of "len" can be converted to use
strncmp().

a31eeae27f remote: use remote_is_configured() for add and rename
Both remote add and remote rename use a slightly different hand-rolled
check if the remote exits.  The hand-rolled check may have some subtle
cases in which it might fail to detect when a remote already exists.
One such case was fixed in fb86e32 ("git remote: allow adding remotes
agreeing with url.<...>.insteadOf").  Another case is when a remote is
configured as follows:

  [remote "foo"]
    vcs = bar

If we try to run `git remote add foo bar` with the above remote
configuration, git segfaults.  This change fixes it.

In addition, git remote rename $existing foo with the configuration for
foo as above silently succeeds, even though foo already exists,
modifying its configuration.  With this patch it fails with "remote foo
already exists".

cc8e538d45 remote: actually check if remote exits
When converting the git remote command to a builtin in 211c89 ("Make

converted from:
       if (!exists $remote->{$name}) {
       	  [...]
to:
       remote = remote_get(argv[1]);
       if (!remote)
          [...]

The new check is not quite correct, because remote_get() never returns
NULL if a name is given.  This leaves us with the somewhat cryptic error
message "error: Could not remove config section 'remote.test'", if we
are trying to remove a remote that does not exist, or a similar error if
we try to rename a remote.

Use the remote_is_configured() function to check whether the remote
actually exists, and die with a more sensible error message ("No such
remote: $remotename") instead if it doesn't.

0ebf4a2af3 worktree: fix "add -B"
Current code does not update "symref" when -B is used. This string
contains the new HEAD. Because it's empty "git worktree add -B" fails at
symbolic-ref step.

Because branch creation is already done before calling add_worktree(),
-B is equivalent to -b from add_worktree() point of view. We do not need
the special case for -B.

de1e67d070 list-objects: pass full pathname to callbacks
When we find a blob at "a/b/c", we currently pass this to
our show_object_fn callbacks as two components: "a/b/" and
"c". Callbacks which want the full value then call
path_name(), which concatenates the two. But this is an
inefficient interface; the path is a strbuf, and we could
simply append "c" to it temporarily, then roll back the
length, without creating a new copy.

So we could improve this by teaching the callsites of
path_name() this trick (and there are only 3). But we can
also notice that no callback actually cares about the
broken-down representation, and simply pass each callback
the full path "a/b/c" as a string. The callback code becomes
even simpler, then, as we do not have to worry about freeing
an allocated buffer, nor rolling back our modification to
the strbuf.

This is theoretically less efficient, as some callbacks
would not bother to format the final path component. But in
practice this is not measurable. Since we use the same
strbuf over and over, our work to grow it is amortized, and
we really only pay to memcpy a few bytes.

bd64516aca list-objects: drop name_path entirely
In the previous commit, we left name_path as a thin wrapper
around a strbuf. This patch drops it entirely. As a result,
every show_object_fn callback needs to be adjusted. However,
none of their code needs to be changed at all, because the
only use was to pass it to path_name(), which now handles
the bare strbuf.

df714f81a7 check_filename: tighten dwim-wildcard ambiguity
When specifying both revisions and pathnames, we allow
"<rev> -- <pathspec>" to be spelled without the "--" as long
as it is not ambiguous. The original logic was something
like:

  1. Resolve each item with get_sha1(). If successful,
     we know it can be a <rev>. Verify that it _isn't_ a
     filename, using verify_non_filename(), and complain of
     ambiguity otherwise.

  2. If get_sha1() didn't succeed, make sure that it _is_
     a file, using verify_filename(). If not, complain
     that it is neither a <rev> nor a <pathspec>.

Both verify_filename() and verify_non_filename() rely on
check_filename(), which definitely said "yes, this is a
file" or "no, it is not" using lstat().

Commit 28fcc0b (pathspec: avoid the need of "--" when
wildcard is used, 2015-05-02) introduced a convenience
feature: check_filename() will consider anything with
wildcard meta-characters as a possible filename, without
even checking the filesystem.

This works well for case 2. For such a wildcard, we would
previously have died and said "it is neither". Post-28fcc0b,
we assume it's a pathspec and proceed.

But it makes some instances of case 1 worse. We may have an
extended sha1 expression that contains meta-characters
(e.g., "HEAD^{/foo.*bar}"), and we now complain that it's
also a filename, due to the wildcard characters (even though
that wildcard would not match anything in the filesystem).

One solution would be to actually expand the pathname and
see if it matches anything on the filesystem. But that's
potentially expensive, and we do not have to be so rigorous
for this DWIM magic (if you want rigor, use "--").

Instead, we can just use different rules for cases 1 and 2.
When we know something is a rev, we will complain only if it
meets a much higher standard for "this is also a file";
namely that it actually exists in the filesystem. Case 2
remains the same: we use the looser "it could be a filename"
standard introduced by 28fcc0b.

We can accomplish this by pulling the wildcard logic out of
check_filename() and putting it into verify_filename(). Its
partner verify_non_filename() does not need a change, since
check_filename() goes back to implementing the "higher
standard".

Besides these two callers of check_filename(), there is one
other: git-checkout does a similar DWIM itself. It hits this
code path only after get_sha1() has returned failure, making
it case 2, which gets the special wildcard treatment.

Note that we drop the tests in t2019 in favor of a more
complete set in t6133. t2019 was not the right place for
them (it's about refname ambiguity, not dwim parsing
ambiguity), and the second test explicitly checked for the
opposite result of the case we are fixing here (which didn't
really make any sense; as shown by the test_must_fail in the
test, it would only serve to annoy people).

2239617526 checkout-index: disallow "--no-stage" option
We do not really expect people to use "--no-stage", but if
they do, git currently segfaults. We could instead have it
undo the effects of a previous "--stage", but this gets
tricky around the "to_tempfile" flag. We cannot simply reset
it to 0, because we don't know if it was set by a previous
"--stage=all" or an explicit "--temp" option.

We could solve this by setting a flag and resolving
to_tempfile later, but it's not worth the effort. Nobody
actually wants to use "--no-stage"; we are just trying to
fix a potential segfault here.

While we're in the area, let's improve the user-facing
messages for this option. The error string should be
translatable, and we should give some hint in the "-h"
output about what can go in the argument field.

6a6df8aa45 checkout-index: handle "--no-index" option
The parsing of "--index" is done in a callback, but it does
not handle an "unset" option. We don't necessarily expect
anyone to use this, but the current behavior is to treat it
exactly like "--index", which would probably be surprising.

Instead, let's just turn it into an OPT_BOOL, and handle it
after we're done parsing. This makes "--no-index" just work
(it cancels a previous "--index").

As a bonus, this makes the logic easier to follow. The old
code opened the index during the option parsing, leaving the
reader to wonder if there was some timing issue (there
isn't; none of the other options care that we've opened it).
And then if we found that "--prefix" had been given, we had
to rollback the index. Now we can simply avoid opening it in
the first place.

Note that it might make more sense for checkout-index to
complain when "--index --prefix=foo" is given (rather than
silently ignoring "--index"), but since it has been that way
since 415e96c ([PATCH] Implement git-checkout-cache -u to
update stat information in the cache., 2005-05-15), it's
safer to leave it as-is.

We can fix this by switching it to an OPT_STRING, which

that this assigns NULL, so we bump our default-case

435ec090ec config: add core.untrackedCache
When we know that mtime on directory as given by the environment
is usable for the purpose of untracked cache, we may want the
untracked cache to be always used without any mtime test or
kernel name check being performed.

Also when we know that mtime is not usable for the purpose of
untracked cache, for example because the repo is shared over a
network file system, we may want the untracked-cache to be
automatically removed from the index.

Allow the user to express such preference by setting the
'core.untrackedCache' configuration variable, which can take
'keep', 'false', or 'true' and default to 'keep'.

When read_index_from() is called, it now adds or removes the
untracked cache in the index to respect the value of this
variable. So it does nothing if the value is `keep` or if the
variable is unset; it adds the untracked cache if the value is
`true`; and it removes the cache if the value is `false`.

`git update-index --[no-|force-]untracked-cache` still adds the
untracked cache to, or removes it, from the index, but this
shows a warning if it goes against the value of
core.untrackedCache, because the next time the index is read
the untracked cache will be added or removed if the
configuration is set to do so.

Also `--untracked-cache` used to check that the underlying
operating system and file system change `st_mtime` field of a
directory if files are added or deleted in that directory. But
because those tests take a long time, `--untracked-cache` no
longer performs them. Instead, there is now
`--test-untracked-cache` to perform the tests. This change
makes `--untracked-cache` the same as `--force-untracked-cache`.

This last change is backward incompatible and should be
mentioned in the release notes.

0571979bd6 tag: do not show ambiguous tag names as "tags/foo"
Since b7cc53e9 (tag.c: use 'ref-filter' APIs, 2015-07-11),
git-tag has started showing tags with ambiguous names (i.e.,
when both "heads/foo" and "tags/foo" exists) as "tags/foo"
instead of just "foo". This is both:

  - pointless; the output of "git tag" includes only
    refs/tags, so we know that "foo" means the one in
    "refs/tags".

and

  - ambiguous; in the original output, we know that the line
    "foo" means that "refs/tags/foo" exists. In the new
    output, it is unclear whether we mean "refs/tags/foo" or
    "refs/tags/tags/foo".

The reason this happens is that commit b7cc53e9 switched
git-tag to use ref-filter's "%(refname:short)" output
formatting, which was adapted from for-each-ref. This more
general code does not know that we care only about tags, and
uses shorten_unambiguous_ref to get the short-name. We need
to tell it that we care only about "refs/tags/", and it
should shorten with respect to that value.

In theory, the ref-filter code could figure this out by us
passing FILTER_REFS_TAGS. But there are two complications
there:

  1. The handling of refname:short is deep in formatting
     code that does not even have our ref_filter struct, let
     alone the arguments to the filter_ref struct.

  2. In git v2.7.0, we expose the formatting language to the
     user. If we follow this path, it will mean that
     "%(refname:short)" behaves differently for "tag" versus
     "for-each-ref" (including "for-each-ref refs/tags/"),
     which can lead to confusion.

Instead, let's add a new modifier to the formatting
language, "strip", to remove a specific set of prefix
components. This fixes "git tag", and lets users invoke the
same behavior from their own custom formats (for "tag" or
"for-each-ref") while leaving ":short" with its same
consistent meaning in all places.

We introduce a test in t7004 for "git tag", which fails
without this patch. We also add a similar test in t3203 for
"git branch", which does not actually fail. But since it is
likely that "branch" will eventually use the same formatting
code, the test helps defend against future regressions.

6d19db1491 update-index: add untracked cache notifications
Attempting to flip the untracked-cache feature on for a random index
file with

    cd /random/unrelated/place
    git --git-dir=/somewhere/else/.git update-index --untracked-cache

would not work as you might expect. Because flipping the feature on
in the index also records the location of the corresponding working
tree (/random/unrelated/place in the above example), when the index
is subsequently used to keep track of files in the working tree in
/somewhere/else, the feature is disabled.

With this patch "git update-index --[test-]untracked-cache" tells the
user in which directory tests are performed. This makes it easy to
spot any problem.

Also in verbose mode, let's tell the user when the cache is enabled
or disabled.

ffd036b128 clean: make is_git_repository a public function
We have always had is_git_directory(), for looking at a
specific directory to see if it contains a git repo. In
0179ca7 (clean: improve performance when removing lots of
directories, 2015-06-15), we added is_git_repository() which
checks for a non-bare repository by looking at its ".git"
entry.

However, the fix in 0179ca7 needs to be applied other
places, too. Let's make this new helper globally available.
We need to give it a better name, though, to avoid confusion
with is_git_directory(). This patch does that, documents
both functions with a comment to reduce confusion, and
removes the clean-specific references in the comments.

99c08d4eb2 ls-remote: add support for showing symrefs
Sometimes it's useful to know the main branch of a git repository
without actually downloading the repository.  This can be done by
looking at the symrefs stored in the remote repository.  Currently git
doesn't provide a simple way to show the symrefs stored on the remote
repository, even though the information is available.  Add a --symref
command line argument to the ls-remote command, which shows the symrefs
in the remote repository.

While there, replace a literal tab in the format string with \t to make
it more obvious to the reader.

d6b16ce914 shortlog: don't warn on empty author
Git tries to avoid creating a commit with an empty author
name or email. However, commits created by older, less
strict versions of git may still be in the history.  There's
not much point in issuing a warning to stderr for an empty
author. The user can't do anything about it now, and we are
better off to simply include it in the shortlog output as an
empty name/email, and let the caller process it however they
see fit.

Older versions of shortlog differentiated between "author
header not present" (which complained) and "author
name/email are blank" (which included the empty ident in the
output).  But since switching to format_commit_message, we
complain to stderr about either case (linux.git has a blank
author deep in its history which triggers this).

We could try to restore the older behavior (complaining only
about the missing header), but in retrospect, there's not
much point in differentiating these cases. A missing
author header is bogus, but as for the "blank" case, the
only useful behavior is to add it to the "empty name"
collection.

9b21a34a96 shortlog: optimize out useless string list

actual list of subject onelines associated with each author.
We care only about the number. So rather than store a
string-list for each author full of "<none>", let's just
keep a count.

This drops my best-of-five for "git shortlog -ns HEAD" on

ed7eba9022 shortlog: optimize out useless "<none>" normalization

If the user asked us only to show counts for each author,

  [after]
  real    0m5.257s

That's only ~7%, but it's so easy to do, there's no good
reason not to. We don't have to touch any downstream code,
since we already fill in the magic string "<none>" to handle

2db6b83d18 shortlog: replace hand-parsing of author with pretty-printer
When gathering the author and oneline subject for each
commit, we hand-parse the commit headers to find the
"author" line, and then continue past to the blank line at
the end of the header.

We can replace this tricky hand-parsing by simply asking the
pretty-printer for the relevant items. This also decouples
the author and oneline parsing, opening up some new
optimizations in further commits.

One reason to avoid the pretty-printer is that it might be
less efficient than hand-parsing. However, I measured no
slowdown at all running "git shortlog -ns HEAD" on
linux.git.

As a bonus, we also fix a memory leak in the (uncommon) case
that the author field is blank.

it was converted to C by b8ec592 (Build in shortlog,

longer matched the raw output.

Given the amount of intervening time without any bug
reports, it's probable that nobody cares. But it's
relatively easy to fix, and the end result is hopefully more
readable than the original.

Note that this no longer matches "author: ", which we did
before, but that has never been a format generated by git.

a7630bd427 ls-files: add eol diagnostics
When working in a cross-platform environment, a user may want to
check if text files are stored normalized in the repository and
if .gitattributes are set appropriately.

Make it possible to let Git show the line endings in the index and
in the working tree and the effective text/eol attributes.

The end of line ("eolinfo") are shown like this:

    "-text"        binary (or with bare CR) file
    "none"         text file without any EOL
    "lf"           text file with LF
    "crlf"         text file with CRLF
    "mixed"        text file with mixed line endings.

The effective text/eol attribute is one of these:

    "", "-text", "text", "text=auto", "text eol=lf", "text eol=crlf"

git ls-files --eol gives an output like this:

    i/none   w/none   attr/text=auto      t/t5100/empty
    i/-text  w/-text  attr/-text          t/test-binary-2.png
    i/lf     w/lf     attr/text eol=lf    t/t5100/rfc2047-info-0007
    i/lf     w/crlf   attr/text eol=crlf  doit.bat
    i/mixed  w/mixed  attr/               locale/XX.po

to show what eol convention is used in the data in the index ('i'),
and in the working tree ('w'), and what attribute is in effect,
for each path that is shown.

Add test cases in t0027.

The program by default reads LF terminated lines, with an option to
use NUL terminated records.  Instead of pretending that there can be
other useful values for line_termination, use a boolean variable,
nul_term_line, to tell if NUL terminated records are used, and
switch between strbuf_getline_{lf,nul} based on it.

8f309aeb82 strbuf: introduce strbuf_getline_{lf,nul}()
The strbuf_getline() interface allows a byte other than LF or NUL as
the line terminator, but this is only because I wrote these
codepaths anticipating that there might be a value other than NUL
and LF that could be useful when I introduced line_termination long
time ago.  No useful caller that uses other value has emerged.

By now, it is clear that the interface is overly broad without a
good reason.  Many codepaths have hardcoded preference to read
either LF terminated or NUL terminated records from their input, and
then call strbuf_getline() with LF or NUL as the third parameter.

This step introduces two thin wrappers around strbuf_getline(),
namely, strbuf_getline_lf() and strbuf_getline_nul(), and
mechanically rewrites these call sites to call either one of
them.  The changes contained in this patch are:

 * introduction of these two functions in strbuf.[ch]

 * mechanical conversion of all callers to strbuf_getline() with
   either '\n' or '\0' as the third parameter to instead call the
   respective thin wrapper.

After this step, output from "git grep 'strbuf_getline('" would
become a lot smaller.  An interim goal of this series is to make
this an empty set, so that we can have strbuf_getline_crlf() take
over the shorter name strbuf_getline().

c8aa9fdf5d strbuf: make strbuf_getline_crlf() global
Often we read "text" files that are supplied by the end user
(e.g. commit log message that was edited with $GIT_EDITOR upon 'git
commit -e'), and in some environments lines in a text file are
terminated with CRLF.  Existing strbuf_getline() knows to read a
single line and then strip the terminating byte from the result, but
it is handy to have a version that is more tailored for a "text"
input that takes both '\n' and '\r\n' as line terminator (aka
<newline> in POSIX lingo) and returns the body of the line after
stripping <newline>.

Recently reimplemented "git am" uses such a function implemented
privately; move it to strbuf.[ch] and make it available for others.

Note that we do not blindly replace calls to strbuf_getline() that
uses LF as the line terminator with calls to strbuf_getline_crlf()
and this is very much deliberate.  Some callers may want to treat an
incoming line that ends with CR (and terminated with LF) to have a
payload that includes the final CR, and such a blind replacement
will result in misconversion when done without code audit.

f5eb87b98d pull: allow interactive rebase with --rebase=interactive
A couple of years ago, I found the need to collaborate on topic
branches that were rebased all the time, and I really needed to see
what I was rebasing when pulling, so I introduced an
interactively-rebasing pull.

The way builtin pull works, this change also supports the value
'interactive' for the 'branch.<name>.rebase' config variable, which
is a neat thing because users can now configure given branches for
interactively-rebasing pulls without having to type out the complete
`--rebase=interactive` option every time they pull.

introduces format.outputDirectory configuration option for same

The case of usage of this configuration option can be convenience
to not pass every time -o/--output-directory if an user has pattern
to store all patches in the /patches directory for example.

The format.outputDirectory has lower priority than command line
option, so if user will set format.outputDirectory and pass the
command line option, a result will be stored in a directory that
passed to command line option.

ee76f92fe8 notes: allow treeish expressions as notes ref
init_notes() is the main point of entry to the notes API. It ensures
that the input can be used as ref, because it needs a ref to update to
store notes tree after modifying it.

There however are many use cases where notes tree is only read, e.g.
"git log --notes=...".  Any notes-shaped treeish could be used for such
purpose, but it is not allowed due to existing restriction.

Allow treeish expressions to be used in the case the notes tree is going
to be used without write "permissions".  Add a flag to distinguish
whether the notes tree is intended to be used read-only, or will be
updated.

With this change, operations that use notes read-only can be fed any
notes-shaped tree-ish can be used, e.g. git log --notes=notes@{1}.

ea56518dfe Handle more file writes correctly in shared repos
In shared repositories, we have to be careful when writing files whose
permissions do not allow users other than the owner to write them.

In particular, we force the marks file of fast-export and the FETCH_HEAD
when fetching to be rewritten from scratch.

This commit does not touch other calls to fopen() that want to
write files:

 - commands that write to working tree files (core.sharedRepository
   does not affect permission bits of working tree files),
   e.g. .rej file created by "apply --reject", result of applying a
   previous conflict resolution by "rerere", "git merge-file".

 - git am, when splitting mails (git-am correctly cleans up its directory
   after finishing, so there is no need to share those files between users)

 - git submodule clone, when writing the .git file, because the file
   will not be overwritten

 - git_terminal_prompt() in compat/terminal.c, because it is not writing to
   a file at all

 - git diff --output, because the output file is clearly not intended to be
   shared between the users of the current repository

 - git fast-import, when writing a crash report, because the reports' file
   names are unique due to an embedded process ID

 - mailinfo() in mailinfo.c, because the output is clearly not intended to
   be shared between the users of the current repository

 - check_or_regenerate_marks() in remote-testsvn.c, because this is only
   used for Git's internal testing

 - git fsck, when writing lost&found blobs (this should probably be
   changed, but left as a low-hanging fruit for future contributors).

Note that this patch does not touch callers of write_file() and
write_file_gently(), which would benefit from the same scrutiny as
to usage in shared repositories.  Most notable users are branch,
daemon, submodule & worktree, and a worrisome call in transport.c
when updating one ref (which ignores the shared flag).

We sometimes use 32-bit unsigned integers as bit-fields.
It's fine to access the MSB, because it's unsigned. However,
doing so as "1 << 31" is wrong, because the constant "1" is

undefined behavior.

7cb5f7c44d blame: fix object casting regression
Commit 1b0d400 refactored the prepare_final() function so
that it could be reused in multiple places. Originally, the
loop had two outputs: a commit to stuff into sb->final, and
the name of the commit from the rev->pending array.

After the refactor, that loop is put in its own function
with a single return value: the object_array_entry from the
rev->pending array. This contains both the name and the object,
but with one important difference: the object is the
_original_ object found by the revision parser, not the
dereferenced commit. If one feeds a tag to "git blame", we
end up casting the tag object to a "struct commit", which
causes a segfault.

Instead, let's return the commit (properly casted) directly
from the function, and take the "name" as an optional
out-parameter. This does the right thing, and actually
simplifies the callers, who no longer need to cast or
dereference the object_array_entry themselves.

b33a15b081 push: add recurseSubmodules config option
The --recurse-submodules command line parameter has existed for some
time but it has no config file equivalent.

Following the style of the corresponding parameter for git fetch, let's
invent push.recurseSubmodules to provide a default for this
parameter. This also requires the addition of --recurse-submodules=no to
allow the configuration to be overridden on the command line when
required.

The most straightforward way to implement this appears to be to make
push use code in submodule-config in a similar way to fetch.

e34f80278e merge-file: clamp exit code to maximum 127
Git-merge-file is documented to return one of three exit
codes:

  - zero means the merge was successful

  - a negative number means an error occurred

  - a positive number indicates the number of conflicts

Unfortunately, this all gets stuffed into an 8-bit return
code. Which means that if you have 256 conflicts, this wraps
to zero, and the merge appears to succeed (and commits a
blob full of conflict-marker cruft!).

This patch clamps the return value to a maximum of 127,
which we should be able to safely represent everywhere. This
also leaves 128-255 for other values. Shells (and some parts
of git) will typically represent signal death as 128 plus
the signal number. And negative values are typically coerced
to an 8-bit unsigned value (so "return -1" ends up as 255).

Technically negative returns have the same problem (e.g.,
"-256" wraps back to 0), but this is not a problem in
practice, as the only negative value we use is "-1".

29abb33978 add: simplify -u/-A without pathspec
Since Git 2.0, "add -u" and "add -A" run from a subdirectory without
any pathspec mean "everything in the working tree" (before 2.0, they
were limited to the current directory).  The limiting to the current
directory was implemented by inserting "." to the command line when
the end user did not give us any pathspec.  At 2.0, we updated the
code to insert ":/" (instead of '.') to consider everything from the
top-level, by using a pathspec magic "top".

The call to parse_pathspec() using the command line arguments is,
however, made with PATHSPEC_PREFER_FULL option since 5a76aff1 (add:
convert to use parse_pathspec, 2013-07-14), which predates Git 2.0.
In retrospect, there was no need to turn "adding . to limit to the
directory" into "adding :/ to unlimit to everywhere" in Git 2.0;
instead we could just have done "if there is no pathspec on the
command line, just let it be".  The parse_pathspec() then would give
us a pathspec that matches everything and all is well.

Incidentally such a simplification also fixes a corner case bug that
stems from the fact that ":/" does not necessarily mean any magic.
A user would say "git --literal-pathspecs add -u :/" from the
command line when she has a directory ':' and wants to add
everything in it (and she knows that her :/ will be taken as
'everything under the sun' magic pathspec unless she disables the
magic with --literal-pathspecs).  The internal use of ':/' would
behave the same way as such an explicitly given ":/" when run with
"--literal-pathspecs", and will not add everything under the sun as
the code originally intended.

05e625e5bf mailinfo: keep the parsed log message in a strbuf
When mailinfo() is eventually libified, the calling "git am" still
will have to write out the log message in the "msg" file for hooks
and other users of the information, but it does not have to reopen
and reread what it wrote earlier if the function kept it in a strbuf.

This also removes the need for seeking and truncating the output
file when we see a scissors mark in the input, which in turn allows
us to lose two callsites of die_errno().

4933910ab7 mailinfo: handle_commit_msg() shouldn't be called after finding patchbreak
There is a strange "if (!mi->cmitmsg) return 0" at the very beginning
of handle_commit_msg(), but the condition should never trigger, because:

 * The only place cmitmsg is set to NULL is after this function sees
   a patch break, closes the FILE * to write the commit log message
   and returns 1.  This function returns non-zero only from that
   codepath.

 * The caller of this function, upon seeing a non-zero return,
   increments filter_stage, starts treating the input as patch text
   and will never call handle_commit_msg() again.

Replace it with an assert(!mi->filter_stage) to ensure the above
observation will stay to be true.

find_boundary().  Pass "line" as a parameter to this leaf function

008ed7df93 tag.c: use the correct algorithm for the '--contains' option
In b7cc53e9 (tag.c: use 'ref-filter' APIs, 2015-09-11) we port tag.c
to use the ref-filter APIs for filtering and printing refs.  In
ref-filter we have two implementations for filtering refs when the
'--contains' option is used.

Although they do the same thing, one is optimized for filtering
branches and the other for tags (borrowed from branch.c and tag.c
respectively) and the 'filter->with_commit_tag_algo' bit decides
which algorithm must be used.  We should unify these.

When we ported tag.c to use ref-filter APIs we missed out on setting
the 'filter->with_commit_tag_algo' bit.  As reported by Jerry
Snitselaar, this causes "git tag --contains" to work way slower than
expected, fix this by setting 'filter->with_commit_tag_algo' in
tag.c before calling 'filter_refs()'.

33e8fc8740 usage: do not insist that standard input must come from a file
The synopsys text and the usage string of subcommands that read list
of things from the standard input are often shown like this:

	git gostak [--distim] < <list-of-doshes>

This is problematic in a number of ways:

 * The way to use these commands is more often to feed them the
   output from another command, not feed them from a file.

 * Manual pages outside Git, commands that operate on the data read
   from the standard input, e.g "sort", "grep", "sed", etc., are not
   described with such a "< redirection-from-file" in their synopsys
   text.  Our doing so introduces inconsistency.

 * We do not insist on where the output should go, by saying

	git gostak [--distim] < <list-of-doshes> > <output>

 * As it is our convention to enclose placeholders inside <braket>,
   the redirection operator followed by a placeholder filename
   becomes very hard to read, both in the documentation and in the
   help text.

Let's clean them all up, after making sure that the documentation
clearly describes the modes that take information from the standard
input and what kind of things are expected on the input.
