517fe807d6 assert NOARG/NONEG behavior of parse-options callbacks
When we define a parse-options callback, the flags we put in the option
struct must match what the callback expects. For example, a callback
which does not handle the "unset" parameter should only be used with
PARSE_OPT_NONEG. But since the callback and the option struct are not
defined next to each other, it's easy to get this wrong (as earlier
patches in this series show).

Fortunately, the compiler can help us here: compiling with
-Wunused-parameters can show us which callbacks ignore their "unset"
parameters (and likewise, ones that ignore "arg" expect to be triggered
with PARSE_OPT_NOARG).

But after we've inspected a callback and determined that all of its
callers use the right flags, what do we do next? We'd like to silence
the compiler warning, but do so in a way that will catch any wrong calls
in the future.

We can do that by actually checking those variables and asserting that
they match our expectations. Because this is such a common pattern,
we'll introduce some helper macros. The resulting messages aren't
as descriptive as we could make them, but the file/line information from
BUG() is enough to identify the problem (and anyway, the point is that
these should never be seen).

Each of the annotated callbacks in this patch triggers
-Wunused-parameters, and was manually inspected to make sure all callers
use the correct options (so none of these BUGs should be triggerable).

fd6263fb73 grep: clean up num_threads handling
When NO_PTHREADS is still used in this file, we have two separate code
paths for thread and no thread support. The latter will always have
num_threads remain zero while the former uses num_threads zero as
"default number of threads".

With recent changes blur the line between thread and no-thread
support, this num_threads handling becomes a bit strange so let's
redefine it like this:

- num_threads == 0 means default number of threads and should become
  positive after all configuration and option parsing is done if
  multithread is supported.

- num_threads <= 1 runs no threads. It does not matter if the platform
  supports threading or not.

- num_threads > 1 will run multiple threads and is invalid if
  HAVE_THREADS is false. pthread API is only used in this case.

PS. a new warning is also added when num_threads is forced back to one
because a thread-incompatible option is specified.

76e9bdc437 submodule: support reading .gitmodules when it's not in the working tree
When the .gitmodules file is not available in the working tree, try
using the content from the index and from the current branch. This
covers the case when the file is part of the repository but for some
reason it is not checked out, for example because of a sparse checkout.

This makes it possible to use at least the 'git submodule' commands
which *read* the gitmodules configuration file without fully populating
the working tree.

Writing to .gitmodules will still require that the file is checked out,
so check for that before calling config_set_in_gitmodules_file_gently.

Add a similar check also in git-submodule.sh::cmd_add() to anticipate
the eventual failure of the "git submodule add" command when .gitmodules
is not safely writeable; this prevents the command from leaving the
repository in a spurious state (e.g. the submodule repository was cloned
but .gitmodules was not updated because
config_set_in_gitmodules_file_gently failed).

Moreover, since config_from_gitmodules() now accesses the global object
store, it is necessary to protect all code paths which call the function
against concurrent access to the global object store. Currently this
only happens in builtin/grep.c::grep_submodules(), so call
grep_read_lock() before invoking code involving
config_from_gitmodules().

Finally, add t7418-submodule-sparse-gitmodules.sh to verify that reading
from .gitmodules succeeds and that writing to it fails when the file is
not checked out.

NOTE: there is one rare case where this new feature does not work
properly yet: nested submodules without .gitmodules in their working
tree.  This has been documented with a warning and a test_expect_failure
item in t7814, and in this case the current behavior is not altered: no
config is read.

0a09e5edc2 grep: add -r/--[no-]recursive
Recognize -r and --recursive as synonyms for --max-depth=-1 for
compatibility with GNU grep; it's still the default for git grep.

This also adds --no-recursive as synonym for --max-depth=0 for free,
which is welcome for completeness and consistency.

Fix the description for --max-depth, while we're at it -- negative
values other than -1 actually disable recursion, i.e. they are
equivalent to --max-depth=0.

1a07e59c3e Update messages in preparation for i18n
Many messages will be marked for translation in the following
commits. This commit updates some of them to be more consistent and
reduce diff noise in those commits. Changes are

- keep the first letter of die(), error() and warning() in lowercase
- no full stop in die(), error() or warning() if it's single sentence
  messages
- indentation
- some messages are turned to BUG(), or prefixed with "BUG:" and will
  not be marked for i18n
- some messages are improved to give more information
- some messages are broken down by sentence to be i18n friendly
  (on the same token, combine multiple warning() into one big string)
- the trailing \n is converted to printf_ln if possible, or deleted
  if not redundant
- errno_errno() is used instead of explicit strerror()

9d8db06eb4 grep.c: teach 'git grep --only-matching'
Teach 'git grep --only-matching', a new option to only print the
matching part(s) of a line.

For instance, a line containing the following (taken from README.md:27):

  (`man gitcvs-migration` or `git help cvs-migration` if git is

Is printed as follows:

  $ git grep --line-number --column --only-matching -e git -- \
    README.md | grep ":27"
  README.md:27:7:git
  README.md:27:16:git
  README.md:27:38:git

The patch works mostly as one would expect, with the exception of a few
considerations that are worth mentioning here.

Like GNU grep, this patch ignores --only-matching when --invert (-v) is
given. There is a sensible answer here, but parity with the behavior of
other tools is preferred.

Because a line might contain more than one match, there are special
considerations pertaining to when to print line headers, newlines, and
how to increment the match column offset. The line header and newlines
are handled as a special case within the main loop to avoid polluting
the surrounding code with conditionals that have large blocks.

6856077ab0 grep: remove "repo" arg from non-supporting funcs
As part of commit f9ee2fcdfa ("grep: recurse in-process using 'struct
repository'", 2017-08-02), many functions in builtin/grep.c were
converted to also take "struct repository *" arguments. Among them were
grep_object() and grep_objects().

However, at least grep_objects() was converted incompletely - it calls
gitmodules_config_oid(), which references the_repository.

But it turns out that the conversion was extraneous anyway - there has
been no user-visible effect - because grep_objects() is never invoked
except with the_repository. This is because grepping through objects
cannot be done recursively into submodules.

Revert the changes to grep_objects() and grep_object() (which conversion
is also extraneous) to show that both these functions do not support
repositories other than the_repository.

90c62155d6 repository: introduce raw object store field
The raw object store field will contain any objects needed for access
to objects in a given repository.

This patch introduces the raw object store and populates it with the
`objectdir`, which used to be part of the repository struct.

As the struct gains members, we'll also populate the function to clear
the memory for these members.

In a later step, we'll introduce a struct object_parser, that will
complement the object parsing in a repository struct: The raw object
parser is the layer that will provide access to raw object content,
while the higher level object parser code will parse raw objects and

b4f5aca40e sha1_file: convert read_sha1_file to struct object_id
Convert read_sha1_file to take a pointer to struct object_id and rename
it read_object_file.  Do the same for read_sha1_file_extended.

Convert one use in grep.c to use the new function without any other code
change, since the pointer being passed is a void pointer that is already
initialized with a pointer to struct object_id.  Update the declaration
and definitions of the modified functions, and apply the following
semantic patch to convert the remaining callers:

38ef24dccf grep: simplify grep_oid and grep_file
In the NO_PTHREADS or !num_threads case, this doesn't change
anything. In the threaded case, note that grep_source_init duplicates
its third argument, so there is no need to keep [path]buf.buf alive
across the call of add_work().

e2e05d619a grep: move grep_source_init outside critical section
grep_source_init typically does three strdup()s, and in the threaded
case, the call from add_work() happens while holding grep_mutex.

We can thus reduce the time we hold grep_mutex by moving the
grep_source_init() call out of add_work(), and simply have add_work()
copy the initialized structure to the available slot in the todo
array.

This also simplifies the prototype of add_work(), since it no longer
needs to duplicate all the parameters of grep_source_init(). In the
callers of add_work(), we get to reduce the amount of code duplicated in
the threaded and non-threaded cases slightly (avoiding repeating the
long "GREP_SOURCE_OID, pathbuf.buf, path, oid" argument list); a
subsequent cleanup patch will make that even more so.

f4f233e13d Merge branch 'bw/pathspec-match-submodule-boundary'
An v2.12-era regression in pathspec match logic, which made it look
into submodule tree even when it is not desired, has been fixed.

* bw/pathspec-match-submodule-boundary:

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.

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()`.

1c0b983a77 Merge branch 'jk/ref-filter-colors-fix'
This is the "theoretically more correct" approach of simply
stepping back to the state before plumbing commands started paying
attention to "color.ui" configuration variable.

Let's run with this one.

* jk/ref-filter-colors-fix:
  tag: respect color.ui config
  Revert "color: check color.ui in git_default_config()"
  Revert "t6006: drop "always" color config tests"

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.
