42bd66816b Merge branch 'nd/ita-cleanup'
Git does not know what the contents in the index should be for a
path added with "git add -N" yet, so "git grep --cached" should not
show hits (or show lack of hits, with -L) in such a path, but that
logic does not apply to "git grep", i.e. searching in the working
tree files.  But we did so by mistake, which has been corrected.

b8e47d1acf grep: fix grepping for "intent to add" files
This reverts commit 4d5520053 (grep: make it clear i-t-a entries are
ignored, 2015-12-27) and adds an alternative fix to maintain the -L
--cached behavior.

4d5520053 caused 'git grep' to no longer find matches in new files in
the working tree where the corresponding index entry had the "intent to
add" bit set, despite the fact that these files are tracked.

The content in the index of a file for which the "intent to add" bit is
set is considered indeterminate and not empty. For most grep queries we
want these to behave the same, however for -L --cached (files without a
match) we don't want to respond positively for "intent to add" files as
their contents are indeterminate. This is in contrast to files with
empty contents in the index (no lines implies no matches for any grep
query expression) which should be reported in the output of a grep -L
--cached invocation.

Add tests to cover this case and a few related cases which previously
lacked coverage.

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.

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".

List of patterns file could come from a DOS editor.

This is iffy; you may actually be trying to find a line with ^M in
it on a system whose line ending is LF.  You can of course work it
around by having a line that has "^M^M^J", let the strbuf_getline()
eat the last "^M^J", leaving just the single "^M" as the pattern.

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().

--no-index option git simply dies.  For convenience, add a

repository.  It defaults to false, preserving the current behavior.

When grep is called with the --quiet option, the pager is initialized

previous commands and not ended with a newline is overwritten:

    $ echo -n aaa; echo bbb
    aaabbb
    $ echo -n aaa; git grep -q foo; echo bbb
    bbb

This can be worked around, for example, by making sure STDOUT is not a
TTY or more directly by setting git's pager to "cat":

    $ echo -n aaa; git grep -q foo > /dev/null; echo bbb
    aaabbb
    $ echo -n aaa; PAGER=cat git grep -q foo; echo bbb
    aaabbb

But prevent calling the pager in the first place, which would also

9e0c3c4fcd make add_object_array_with_context interface more sane
When you resolve a sha1, you can optionally keep any context
found during the resolution, including the path and mode of
a tree entry (e.g., when looking up "HEAD:subdir/file.c").

The add_object_array_with_context function lets you then
attach that context to an entry in a list. Unfortunately,
the interface for doing so is horrible. The object_context
structure is large and most object_array users do not use
it. Therefore we keep a pointer to the structure to avoid
burdening other users too much. But that means when we do
use it that we must allocate the struct ourselves. And the
struct contains a fixed PATH_MAX-sized buffer, which makes
this wholly unsuitable for any large arrays.

We can observe that there is only a single user of the
"with_context" variant: builtin/grep.c. And in that use
case, the only element we care about is the path. We can
therefore store only the path as a pointer (the context's
mode field was redundant with the object_array_entry itself,
and nobody actually cared about the surrounding tree). This
still requires a strdup of the pathname, but at least we are
only consuming the minimum amount of memory for each string.

We can also handle the copying ourselves in
add_object_array_*, and free it as appropriate in
object_array_release_entry.

When <command> happens to be the magic string "less", today

	git grep -O<command> -e<pattern>

helpfully passes +/<pattern> to less so you can navigate through
the results within a file using the n and shift+n keystrokes.

Alas, that doesn't do the right thing for a case-insensitive match,
i.e.

	git grep -i -O<command> -e<pattern>

For that case we should pass --IGNORE-CASE to "less" so that n and
shift+n can move between results ignoring case in the pattern.

The original patch came from msysgit and used "-i", but that was not
due to lack of support for "-I" but it merely overlooked that it
ought to work even when the pattern contains capital letters.

26ecfe3e20 grep: use run-command's "dir" option for --open-files-in-pager
Git generally changes directory to the repository root on
startup.  When running "grep --open-files-in-pager" from a
subdirectory, we chdir back to the original directory before
running the pager, so that we can feed the relative
pathnames to the pager.

We currently do this chdir manually, but we can ask
run_command to do it for us. This is fewer lines of code,
and as a bonus, the chdir is limited to the child process,
which avoids any unexpected surprises for code running after
the pager (there isn't any currently, but this is
future-proofing).

This helps reduce the number of match_pathspec_depth() call sites and
show how m_p_d() is used. And it usage is:

 - match against an index entry (ce_path_match or match_pathspec_depth
   in ls-files)

 - match against a dir_entry from read_directory (dir_path_match and
   match_pathspec_depth in clean.c, which will be converted later)

 - resolve-undo (rerere.c and ls-files.c)

d5d09d4754 Replace deprecated OPT_BOOLEAN by OPT_BOOL
This task emerged from b04ba2bb (parse-options: deprecate OPT_BOOLEAN,
2011-09-27). All occurrences of the respective variables have
been reviewed and none of them relied on the counting up mechanism,
but all of them were using the variable as a true boolean.

This patch does not change semantics of any command intentionally.

6330a17199 parse_pathspec: add special flag for max_depth feature
match_pathspec_depth() and tree_entry_interesting() check max_depth
field in order to support "git grep --max-depth". The feature
activation is tied to "recursive" field, which led to some unwanted
activation, e.g. 5c8eeb8 (diff-index: enable recursive pathspec
matching in unpack_trees - 2012-01-15).

This patch decouples the activation from "recursive" field, puts it in
"magic" field instead. This makes sure that only "git grep" can
activate this feature. And because parse_pathspec knows when the
feature is not used, it does not need to sort pathspec (required for
max_depth to work correctly). A small win for non-grep cases.

Even though a new magic flag is introduced, no magic syntax is. The
magic can be only enabled by parse_pathspec() caller. We might someday
want to support ":(maxdepth:10)src." It all depends on actual use
cases.

max_depth feature cannot be enabled via init_pathspec() anymore. But
that's ok because init_pathspec() is on its way to /dev/null.

These call sites follow the pattern:

   paths = get_pathspec(prefix, argv);
   init_pathspec(&pathspec, paths);

which can be converted into a single parse_pathspec() call.

9c5e6c802c Convert "struct cache_entry *" to "const ..." wherever possible
I attempted to make index_state->cache[] a "const struct cache_entry **"
to find out how existing entries in index are modified and where. The
question I have is what do we do if we really need to keep track of on-disk
changes in the index. The result is

 - diff-lib.c: setting CE_UPTODATE

 - name-hash.c: setting CE_HASHED

 - preload-index.c, read-cache.c, unpack-trees.c and
   builtin/update-index: obvious

 - entry.c: write_entry() may refresh the checked out entry via
   fill_stat_cache_info(). This causes "non-const struct cache_entry
   *" in builtin/apply.c, builtin/checkout-index.c and
   builtin/checkout.c

 - builtin/ls-files.c: --with-tree changes stagemask and may set
   CE_UPDATE

Of these, write_entry() and its call sites are probably most
interesting because it modifies on-disk info. But this is stat info
and can be retrieved via refresh, at least for porcelain
commands. Other just uses ce_flags for local purposes.

So, keeping track of "dirty" entries is just a matter of setting a
flag in index modification functions exposed by read-cache.c. Except
unpack-trees, the rest of the code base does not do anything funny
behind read-cache's back.

The actual patch is less valueable than the summary above. But if
anyone wants to re-identify the above sites. Applying this patch, then
this:

    diff --git a/cache.h b/cache.h
    index 430d021..1692891 100644
    --- a/cache.h
    +++ b/cache.h
    @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode)
     #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1)

     struct index_state {

    +	const struct cache_entry **cache;
     	unsigned int version;
     	unsigned int cache_nr, cache_alloc, cache_changed;
     	struct string_list *resolve_undo;

will help quickly identify them without bogus warnings.

39598f9983 quote_path_relative(): remove redundant parameter
quote_path_relative() used to take a counted string as its parameter
(the string to be quoted).  With an earlier change, it now uses
relative_path() that does not take a counted string, and we have
been passing only the pointer to the string since then.

Remove the length parameter from quote_path_relative() to show that
this parameter was redundant.  All the changed lines show that the
caller passed either -1 (to ask the function run strlen() on the
string), or the length of the string, so the earlier conversion was
safe.

All the callers of quote_path_relative() that used to take counted string
have been audited to make sure that they are passing length of the actual
string (or -1 to ask the callee run strlen())
