33e0f62ba9 pathspec: rename per-item field has_wildcard to use_wildcard
As the point of the last change is to allow use of strings as
literals no matter what characters are in them, "has_wildcard"
does not match what we use this field for anymore.

It is used to decide if the wildcard matching should be used, so
rename it to match the usage better.

0235017eaf clean: unreadable directory may still be rmdir-able if it is empty
As a last ditch effort, try rmdir(2) when we cannot read the directory
to be removed.  It may be an empty directory that we can remove without
any permission, as long as we can modify its parent directory.

Noticed by Linus.

get_relative_cwd's only user is is_inside_dir, we can kill it for

Rename the make_*_path functions so it's clearer what they do, in

make_nonrelative_path is by renaming them real_path and absolute_path

renamed to relative_path to maintain the name convention.

61cf282045 pathspec: add match_pathspec_depth()
match_pathspec_depth() is a clone of match_pathspec() except that it
can take depth limit. Computation is a bit lighter compared to
match_pathspec() because it's usually precomputed and stored in struct
pathspec.

In long term, match_pathspec() and match_one() should be removed in
favor of this function.

86e4ca69e3 tree_entry_interesting(): fix depth limit with overlapping pathspecs
Suppose we have two pathspecs 'a' and 'a/b' (both are dirs) and depth
limit 1. In current code, pathspecs are checked in input order. When
'a/b' is checked against pathspec 'a', it fails depth limit and
therefore is excluded, although it should match 'a/b' pathspec.

This patch reorders all pathspecs alphabetically, then teaches
tree_entry_interesting() to check against the deepest pathspec first,
so depth limit of a shallower pathspec won't affect a deeper one.

bc96cc87db tree_entry_interesting(): support depth limit
This is needed to replace pathspec_matches() in builtin/grep.c.

max_depth == -1 means infinite depth. Depth limit is only effective
when pathspec.recursive == 1. When pathspec.recursive == 0, the
behavior depends on match functions: non-recursive for
tree_entry_interesting() and recursive for match_pathspec{,_depth}

0602f3e916 Add struct pathspec
The old pathspec structure remains as pathspec.raw[]. New things are
stored in pathspec.items[]. There's no guarantee that the pathspec
order in raw[] is exactly as in items[].

raw[] is external (source) data and is untouched by pathspec
manipulation functions. It eases migration from old const char ** to

fbbb4e19be get_cwd_relative(): do not misinterpret root path
Commit 490544b (get_cwd_relative(): do not misinterpret suffix as
subdirectory) handles case where:

dir = "/path/work";
cwd = "/path/work-xyz";

When it comes to the end of get_cwd_relative(), dir is at '\0' and cwd
is at '-'. The rest of cwd, "-xyz", clearly cannot be the relative
path from dir to cwd. However there is another case where:

dir = "/";          /* or even "c:/" */
cwd = "/path/to/here";

In this special case, while *cwd == 'p', which is not a path
separator, the rest of cwd, "path/to/here", can be returned as a
relative path from dir to cwd.

Handle this case and make t1509 pass again.

21444f1805 Add case insensitivity support when using git ls-files
When mydir/filea.txt is added, mydir/ is renamed to MyDir/, and
MyDir/fileb.txt is added, running git ls-files mydir only shows
mydir/filea.txt. Running git ls-files MyDir shows MyDir/fileb.txt.
Running git ls-files mYdIR shows nothing.

With this patch running git ls-files for mydir, MyDir, and mYdIR shows
mydir/filea.txt and MyDir/fileb.txt.

Wildcards are not handled case insensitively in this patch. Example:
MyDir/aBc/file.txt is added. git ls-files MyDir/a* works fine, but git
ls-files mydir/a* does not.

5102c6173c Add case insensitivity support for directories when using git status
When using a case preserving but case insensitive file system, directory
case can differ but still refer to the same physical directory.  git
status reports the directory with the alternate case as an Untracked
file.  (That is, when mydir/filea.txt is added to the repository and
then the directory on disk is renamed from mydir/ to MyDir/, git status
shows MyDir/ as being untracked.)

Support has been added in name-hash.c for hashing directories with a
terminating slash into the name hash. When index_name_exists() is called
with a directory (a name with a terminating slash), the name is not
found via the normal cache_name_compare() call, but it is found in the
slow_same_name() function.

Additionally, in dir.c, directory_exists_in_index_icase() allows newly
added directories deeper in the directory chain to be identified.

Ultimately, it would be better if the file list was read in case
insensitive alphabetical order from disk, but this change seems to
suffice for now.

The end result is the directory is looked up in a case insensitive
manner and does not show in the Untracked files list.

10d4b02b99 Case insensitivity support for .gitignore via core.ignorecase
This is especially beneficial when using Windows and Perforce and the
git-p4 bridge. Internally, Perforce preserves a given file's full path
including its case at the time it was added to the Perforce repository.
When syncing a file down via Perforce, missing directories are created,
if necessary, using the case as stored with the filename. Unfortunately,
two files in the same directory can have differing cases for their
respective paths, such as /diRa/file1.c and /DirA/file2.c. Depending on
sync order, DirA/ may get created instead of diRa/.

It is possible to handle directory names in a case insensitive manner
without this patch, but it is highly inconvenient, requiring each
character to be specified like so: [Bb][Uu][Ii][Ll][Dd]. With this patch, the
gitignore exclusions honor the core.ignorecase=true configuration
setting and make the process less error prone. The above is specified
like so: Build

8cf2a84e9d Add string comparison functions that respect the ignore_case variable.
Multiple locations within this patch series alter a case sensitive
string comparison call such as strcmp() to be a call to a string
comparison call that selects case comparison based on the global
ignore_case variable. Behaviorally, when core.ignorecase=false, the
*_icase() versions are functionally equivalent to their C runtime
counterparts.  When core.ignorecase=true, the *_icase() versions perform
a case insensitive comparison.

Like Linus' earlier ignorecase patch, these may ignore filename
conventions on certain file systems. By isolating filename comparisons
to certain functions, support for those filename conventions may be more
easily met.

42f9852f3c common_prefix: simplify and fix scanning for prefixes
common_prefix() scans backwards from the far end of each 'next'
pathspec, starting from 'len', shortening the 'prefix' using 'path' as
a reference.

However, there is a small opportunity for an out-of-bounds access
because len is unconditionally set to prefix-1 after a "direct match"
test failed.  This means that if 'next' is shorter than prefix+2, we
read past it.

Instead of a minimal fix, simplify the loop: scan *forward* over the
'next' entry, remembering the last '/' where it matched the prefix
known so far.  This is far easier to read and also has the advantage
that we only scan over each entry once.

4b05548fc0 enums: omit trailing comma for portability
Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX
5.1 fails to compile git.

enum style is inconsistent already, with some enums declared on one
line, some over 3 lines with the enum values all on the middle line,
sometimes with 1 enum value per line... and independently of that the
trailing comma is sometimes present and other times absent, often
mixing with/without trailing comma styles in a single file, and
sometimes in consecutive enum declarations.

Clearly, omitting the comma is the more portable style, and this patch
changes all enum declarations to use the portable omitted dangling
comma style consistently.

29209cbe58 dir: fix COLLECT_IGNORED on excluded prefixes
As we walk the directory tree, if we see an ignored path, we
want to add it to the ignored list only if it matches any
pathspec that we were given. We used to check for the
pathspec to appear explicitly. E.g., if we see "subdir/file"
and it is excluded, we check to see if we have "subdir/file"
in our pathspec.

However, this interacts badly with the optimization to avoid
recursing into ignored subdirectories. If "subdir" as a
whole is ignored, then we never recurse, and consider only
whether "subdir" itself is in our pathspec.  It would not
match a pathspec of "subdir/file" explicitly, even though it
is the reason that subdir/file would be excluded.

This manifests itself to the user as "git add subdir/file"
failing to correctly note that the pathspec was ignored.

This patch extends the in_pathspec logic to include prefix
directory case.

45d76f1718 Fix memory corruption when .gitignore does not end by \n
Commit b5041c5 (Avoid writing to buffer in add_excludes_from_file_1())
tried not to append '\n' at the end because the next commit
may return a buffer that does not have extra space for that.

Unfortunately it left this assignment in the loop:

  buf[i - (i && buf[i-1] == '\r')] = 0;

that can corrupt memory if "buf" is not '\n' terminated. But even if
it does not corrupt memory, the last line would not be
NULL-terminated, leading to errors later inside add_exclude().

This patch fixes it by reverting the faulty commit and make
sure "buf" is always \n terminated.

While at it, free unused memory properly.

48ffef966c ls-files: fix overeager pathspec optimization
Given pathspecs that share a common prefix, ls-files optimized its call
into recursive directory reader by starting at the common prefix
directory.

If you have a directory "t" with an untracked file "t/junk" in it, but the
top-level .gitignore file told us to ignore "t/", this resulted in:

    $ git ls-files -o --exclude-standard
    $ git ls-files -o --exclude-standard t/
    t/junk
    $ git ls-files -o --exclude-standard t/junk
    t/junk
    $ cd t && git ls-files -o --exclude-standard
    junk

We could argue that you are overriding the ignore file by giving a
patchspec that matches or being in that directory, but it is somewhat
unexpected.  Worse yet, these behave differently:

    $ git ls-files -o --exclude-standard t/ .
    $ git ls-files -o --exclude-standard t/
    t/junk

This patch changes the optimization so that it notices when the common
prefix directory that it starts reading from is an ignored one.

c28b3d6e7b Read .gitignore from index if it is skip-worktree
This adds index as a prerequisite for directory listing (with
exclude).  At the moment directory listing is used by "git clean",
"git add", "git ls-files" and "git status"/"git commit" and
unpack_trees()-related commands.  These commands have been
checked/modified to populate index before doing directory listing.

add_excludes_from_file() does not enable this feature, because it
is used to read .git/info/exclude and some explicit files specified
by "git ls-files".

1d8842d921 Add 'fill_directory()' helper function for directory traversal
Most of the users of "read_directory()" actually want a much simpler
interface than the whole complex (but rather powerful) one.

In fact 'git add' had already largely abstracted out the core interface
issues into a private "fill_directory()" function that was largely
applicable almost as-is to a number of callers.  Yes, 'git add' wants to
do some extra work of its own, specific to the add semantics, but we can
easily split that out, and use the core as a generic function.

This function does exactly that, and now that much simplified
'fill_directory()' function can be shared with a number of callers,
while also ensuring that the rather more complex calling conventions of
read_directory() are used by fewer call-sites.

This also makes the 'common_prefix()' helper function private to dir.c,
since all callers are now in that file.

6e4f981ffb git-add: no need for -f when resolving a conflict in already tracked path
When a path F that matches ignore pattern has a conflict, "git add F"
insisted the -f option be given, which did not make sense.  It would have
required -f when the path was originally added, but when resolving a
conflict, it already is tracked.

So this should work (and does):

  $ echo file >.gitignore
  $ echo content >file
  $ git add -f file ;# need -f because we are adding new path
  $ echo more content >>file
  $ git add file ;# don't need -f; it is not actually an "other" file

This is handled under the hood by the COLLECT_IGNORED option to
read_directory. When that code finds an ignored file, it checks the
index to make sure it is not actually a tracked file. However, the test
it uses does not take into account unmerged entries, and considers them
to still be ignored. "git ls-files" uses a more elaborate test and gets
the right answer and the same test should be used here.

da4b3e8c28 dir.c: clean up handling of 'path' parameter in read_directory_recursive()
Right now we pass two different pathnames ('path' and 'base') down to
read_directory_recursive(), and the only real reason for that is that we
want to allow an empty 'base' parameter, but when we do so, we need the
pathname to "opendir()" to be "." rather than the empty string.

And rather than handle that confusion in the caller, we can just fix
read_directory_recursive() to handle the case of an empty path itself,
by just passing opendir() a "." ourselves if the path is empty.

This would allow us to then drop one of the pathnames entirely from the
calling convention, but rather than do that, we'll start separating them
out as a "filesystem pathname" (the one we use for filesystem accesses)
and a "git internal base name" (which is the name that we use for git
internally).

That will eventually allow us to do things like handle different
encodings (eg the filesystem pathnames might be Latin1, while git itself
would use UTF-8 for filename information).

fnmatch, but this was not done for other rules since they used strcmp
instead.  A file named "#foo" would not be excluded by "\#foo", but would
be excluded by "\#foo*".

We now treat all rules with "\" as wildcard rules.

Another solution could be to de-escape all non-wildcard rules as we
read them, but we would have to do the de-escaping exactly as fnmatch
does it to avoid inconsistencies.

88ea8112b4 Optimize match_pathspec() to avoid fnmatch()
"git add *" is actually fundamentally different from "git add .", and
yeah, you should generally use the latter.

The reason? The argument list is actually something different from what
you think it is. For git, it's a "pathspec", so what actualy happens is
that in *both* cases, it will really traverse the whole tree, and then
match every file it finds against the pathspec.

So think of the arguments not as a file list, but as a random bunch of
patterns to match against the files you have!

Which is why the cost is actually approximately O(n*m), where "n" is the
size of the working tree, and "m" is the number of pathspecs.

So the reason "git add ." is fast is actually that "m" in that case is
just 1 (just one trivial pattern), and then "git add *" is slow because
"m" is large (lots of complicated patterns). In both cases, 'n' is the
same (== the whole set of files in your working tree).

Anyway, here's a trivial patch that doesn't change this fundamental fact,
but that avoids doing anything *expensive* until we've done some cheap
initial tests. It may or may not help your test-case, but it's pretty
simple and it matches the other git optimizations in this area (ie
"conceptually handle the general case, but optimize the simple cases where
we can exit early")

Notice how this patch doesn' actually change the fundamental O(n^2)
behaviour, but it makes it much cheaper by generally avoiding the
expensive 'fnmatch' and 'strlen/strncmp' when they are obviously not
needed.

The fix is to send len which could be shorter than ent->len because we

match_one() was modified to allow a name[] that is not NUL terminated.
This allows us to check if the name matched the pathspec exactly

8e0f70033b Avoid unnecessary "if-before-free" tests.
This change removes all obvious useless if-before-free tests.
E.g., it replaces code like this:

        if (some_expression)
                free (some_expression);

with the now-equivalent:

        free (some_expression);

It is equivalent not just because POSIX has required free(NULL)
to work for a long time, but simply because it has worked for
so long that no reasonable porting target fails the test.
Here's some evidence from nearly 1.5 years ago:

    http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html

FYI, the change below was prepared by running the following:

  git ls-files -z | xargs -0 \
  perl -0x3b -pi -e \
    's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s'

Note however, that it doesn't handle brace-enclosed blocks like
"if (x) { free (x); }".  But that's ok, since there were none like
that in git sources.

Beware: if you do use the above snippet, note that it can
produce syntactically invalid C code.  That happens when the
affected "if"-statement has a matching "else".
E.g., it would transform this

  if (x)
    free (x);
  else
    foo ();

into this:

  free (x);
  else
    foo ();

There were none of those here, either.

If you're interested in automating detection of the useless
tests, you might like the useless-if-before-free script in gnulib:
[it *does* detect brace-enclosed free statements, and has a --name=S
 option to make it detect free-like functions with different names]

6831a88ac0 gitignore: lazily find dtype
When we process "foo/" entries in gitignore files on a system
that does not have d_type member in "struct dirent", the earlier
implementation ran lstat(2) separately when matching with
entries that came from the command line, in-tree .gitignore
files, and $GIT_DIR/info/excludes file.

This optimizes it by delaying the lstat(2) call until it becomes
absolutely necessary.

The initial idea for this change was by Jeff King, but I
optimized it further to pass pointers to around.

d6b8fc303b gitignore(5): Allow "foo/" in ignore list to match directory "foo"
A pattern "foo/" in the exclude list did not match directory
"foo", but a pattern "foo" did.  This attempts to extend the
exclude mechanism so that it would while not matching a regular
file or a symbolic link "foo".  In order to differentiate a
directory and non directory, this passes down the type of path
being checked to excluded() function.

A downside is that the recursive directory walk may need to run
lstat(2) more often on systems whose "struct dirent" do not give
the type of the entry; earlier it did not have to do so for an
excluded path, but we now need to figure out if a path is a
directory before deciding to exclude it.  This is especially bad
because an idea similar to the earlier CE_UPTODATE optimization
to reduce number of lstat(2) calls would by definition not apply
to the codepaths involved, as (1) directories will not be
registered in the index, and (2) excluded paths will not be in
the index anyway.

cf558704fb Create pathname-based hash-table lookup into index
This creates a hash index of every single file added to the index.
Right now that hash index isn't actually used for much: I implemented a
"cache_name_exists()" function that uses it to efficiently look up a
filename in the index without having to do the O(logn) binary search,
but quite frankly, that's not why this patch is interesting.

No, the whole and only reason to create the hash of the filenames in the
index is that by modifying the hash function, you can fairly easily do
things like making it always hash equivalent names into the same bucket.

That, in turn, means that suddenly questions like "does this name exist
in the index under an _equivalent_ name?" becomes much much cheaper.

Guiding principles behind this patch:

 - it shouldn't be too costly. In fact, my primary goal here was to
   actually speed up "git commit" with a fully populated kernel tree, by
   being faster at checking whether a file already existed in the index. I
   did succeed, but only barely:

	Best before:
		[torvalds@woody linux]$ time git commit > /dev/null
		real    0m0.255s
		user    0m0.168s
		sys     0m0.088s

	Best after:

		[torvalds@woody linux]$ time ~/git/git commit > /dev/null
		real    0m0.233s
		user    0m0.144s
		sys     0m0.088s

   so some things are actually faster (~8%).

   Caveat: that's really the best case. Other things are invariably going
   to be slightly slower, since we populate that index cache, and quite
   frankly, few things really use it to look things up.

   That said, the cost is really quite small. The worst case is probably
   doing a "git ls-files", which will do very little except puopulate the
   index, and never actually looks anything up in it, just lists it.

	Before:
		[torvalds@woody linux]$ time git ls-files > /dev/null
		real    0m0.016s
		user    0m0.016s
		sys     0m0.000s

	After:
		[torvalds@woody linux]$ time ~/git/git ls-files > /dev/null
		real    0m0.021s
		user    0m0.012s
		sys     0m0.008s

   and while the thing has really gotten relatively much slower, we're
   still talking about something almost unmeasurable (eg 5ms). And that
   really should be pretty much the worst case.

   So we lose 5ms on one "benchmark", but win 22ms on another. Pick your
   poison - this patch has the advantage that it will _likely_ speed up
   the cases that are complex and expensive more than it slows down the
   cases that are already so fast that nobody cares. But if you look at
   relative speedups/slowdowns, it doesn't look so good.

 - It should be simple and clean

   The code may be a bit subtle (the reasons I do hash removal the way I
   do etc), but it re-uses the existing hash.c files, so it really is
   fairly small and straightforward apart from a few odd details.

Now, this patch on its own doesn't really do much, but I think it's worth
looking at, if only because if done correctly, the name hashing really can
make an improvement to the whole issue of "do we have a filename that
looks like this in the index already". And at least it gets real testing
by being used even by default (ie there is a real use-case for it even
without any insane filesystems).

NOTE NOTE NOTE! The current hash is a joke. I'm ashamed of it, I'm just
not ashamed of it enough to really care. I took all the numbers out of my
nether regions - I'm sure it's good enough that it works in practice, but
the whole point was that you can make a really much fancier hash that
hashes characters not directly, but by their upper-case value or something
like that, and thus you get a case-insensitive hash, while still keeping
the name and the index itself totally case sensitive.

7a51ed66f6 Make on-disk index representation separate from in-core one
This converts the index explicitly on read and write to its on-disk

In particular, the in-core format is now host-endian (as opposed to the
on-disk one that is network endian in order to be able to be shared
across machines) and as a result we can dispense with all the
htonl/ntohl on accesses to the cache_entry fields.

This will make it easier to make use of various temporary flags that do

63d285c849 per-directory-exclude: lazily read .gitignore files
Operations that walk directories or trees, which potentially need to
consult the .gitignore files, used to always try to open the .gitignore
file every time they entered a new directory, even when they ended up
not needing to call excluded() function to see if a path in the
directory is ignored.  This was done by push/pop exclude_per_directory()
functions that managed the data in a stack.

This changes the directory walking API to remove the need to call these
two functions.  Instead, the directory walk data structure caches the
data used by excluded() function the last time, and lazily reuses it as
much as possible.  Among the data the last check used, the ones from
deeper directories that the path we are checking is outside are
discarded, data from the common leading directories are reused, and then
the directories between the common directory and the directory the path
being checked is in are checked for .gitignore file.  This is very
similar to the way gitattributes are handled.

This API change also fixes "ls-files -c -i", which called excluded()
without setting up the gitignore data via the old push/pop functions.

41a7aa588f Fix per-directory exclude handing for "git add"
In "dir_struct", each exclusion element in the exclusion stack records a
base string (pointer to the beginning with length) so that we can tell
where it came from, but this pointer is just pointing at the parameter
that is given by the caller to the push_exclude_per_directory()
function.

While read_directory_recursive() runs, calls to excluded() makes use
the data in the exclusion elements, including this base string.  The
caller of read_directory_recursive() is not supposed to free the
buffer it gave to push_exclude_per_directory() earlier, until it
returns.

was simplified and added to the t3700 test.

039bc64e88 core.excludesfile clean-up
There are inconsistencies in the way commands currently handle
the core.excludesfile configuration variable.  The problem is
the variable is too new to be noticed by anything other than
git-add and git-status.

 * git-ls-files does not notice any of the "ignore" files by
   default, as it predates the standardized set of ignore files.
   The calling scripts established the convention to use
   .git/info/exclude, .gitignore, and later core.excludesfile.

 * git-add and git-status know about it because they call
   add_excludes_from_file() directly with their own notion of
   which standard set of ignore files to use.  This is just a
   stupid duplication of code that need to be updated every time
   the definition of the standard set of ignore files is
   changed.

 * git-read-tree takes --exclude-per-directory=<gitignore>,
   not because the flexibility was needed.  Again, this was
   because the option predates the standardization of the ignore
   files.

 * git-merge-recursive uses hardcoded per-directory .gitignore
   and nothing else.  git-clean (scripted version) does not
   honor core.* because its call to underlying ls-files does not
   know about it.  git-clean in C (parked in 'pu') doesn't either.

We probably could change git-ls-files to use the standard set
when no excludes are specified on the command line and ignore
processing was asked, or something like that, but that will be a
change in semantics and might break people's scripts in a subtle
way.  I am somewhat reluctant to make such a change.

On the other hand, I think it makes perfect sense to fix
git-read-tree, git-merge-recursive and git-clean to follow the
same rule as other commands.  I do not think of a valid use case
to give an exclude-per-directory that is nonstandard to
read-tree command, outside a "negative" test in the t1004 test
script.

This patch is the first step to untangle this mess.

The next step would be to teach read-tree, merge-recursive and
clean (in C) to use setup_standard_excludes().

That happened in the case of a pathname that was ignored, and we did
not ask for "dir->show_ignored". That test used to be *together*
with the "DTYPE(de) != DT_DIR", but splitting the two tests up
means that we can do that (common) test before we even bother to
calculate the real dtype.

Of course, that optimization only matters for systems that don't
have, or don't fill in DTYPE properly.

I also clarified the real relationship between "exclude" and
"dir->show_ignored". It used to do

	if (exclude != dir->show_ignored) {
		..

which wasn't exactly obvious, because it triggers for two different
cases:

 - the path is marked excluded, but we are not interested in ignored
   files: ignore it

 - the path is *not* excluded, but we *are* interested in ignored
   files: ignore it unless it's a directory, in which case we might
   have ignored files inside the directory and need to recurse
   into it).

so this splits them into those two cases, since the first case
doesn't even care about the type.

I also made a the DT_UNKNOWN case a separate helper function,
and added some commentary to the cases.

e96980ef81 builtin-add: simplify (and increase accuracy of) exclude handling
Previously, the code would always set up the excludes, and then manually
pick through the pathspec we were given, assuming that non-added but
existing paths were just ignored. This was mostly correct, but would
erroneously mark a totally empty directory as 'ignored'.

Instead, we now use the collect_ignored option of dir_struct, which
unambiguously tells us whether a path was ignored. This simplifies the
code, and means empty directories are now just not mentioned at all.

Furthermore, we now conditionally ask dir_struct to respect excludes,
depending on whether the '-f' flag has been set. This means we don't have
to pick through the result, checking for an 'ignored' flag; ignored entries
were either added or not in the first place.

We can safely get rid of the special 'ignored' flags to dir_entry, which
were not used anywhere else.

c7f34c180b dir.c(common_prefix): Fix two bugs
The function common_prefix() is used to find the common subdirectory of
a couple of pathnames. When checking if the next pathname matches up with
the prefix, it incorrectly checked the whole path, not just the prefix
(including the slash). Thus, the expensive part of the loop was executed
always.

The other bug is more serious: if the first and the last pathname in the
list have a longer common prefix than the common prefix for _all_ pathnames
in the list, the longer one would be chosen. This bug was probably hidden
by the fact that bash's wildcard expansion sorts the results, and the code
just so happens to work with sorted input.

095952585c Teach directory traversal about subprojects
This is the promised cleaned-up version of teaching directory traversal
(ie the "read_directory()" logic) about subprojects. That makes "git add"
understand to add/update subprojects.

It now knows to look at the index file to see if a directory is marked as
a subproject, and use that as information as whether it should be recursed
into or not.

It also generally cleans up the handling of directory entries when
traversing the working tree, by splitting up the decision-making process
into small functions of their own, and adding a fair number of comments.

Finally, it teaches "add_file_to_cache()" that directory names can have
slashes at the end, since the directory traversal adds them to make the
difference between a file and a directory clear (it always did that, but
my previous too-ugly-to-apply subproject patch had a totally different
path for subproject directories and avoided the slash for that case).

9fc42d6091 Optimize directory listing with pathspec limiter.
The way things are set up, you can now pass a "pathspec" to the
"read_directory()" function. If you pass NULL, it acts exactly
like it used to do (read everything). If you pass a non-NULL
pointer, it will simplify it into a "these are the prefixes
without any special characters", and stop any readdir() early if
the path in question doesn't match any of the prefixes.

NOTE! This does *not* obviate the need for the caller to do the *exact*
pathspec match later. It's a first-level filter on "read_directory()", but
it does not do the full pathspec thing. Maybe it should. But in the
meantime, builtin-add.c really does need to do first

	read_directory(dir, .., pathspec);
	if (pathspec)
		prune_directory(dir, pathspec, baselen);

ie the "prune_directory()" part will do the *exact* pathspec pruning,
while the "read_directory()" will use the pathspec just to do some quick
high-level pruning of the directories it will recurse into.

dc49cd769b Cast 64 bit off_t to 32 bit size_t
Some systems have sizeof(off_t) == 8 while sizeof(size_t) == 4.
This implies that we are able to access and work on files whose
maximum length is around 2^63-1 bytes, but we can only malloc or
mmap somewhat less than 2^32-1 bytes of memory.

On such a system an implicit conversion of off_t to size_t can cause
the size_t to wrap, resulting in unexpected and exciting behavior.
Right now we are working around all gcc warnings generated by the
-Wshorten-64-to-32 option by passing the off_t through xsize_t().

In the future we should make xsize_t on such problematic platforms
detect the wrapping and die if such a file is accessed.

93d26e4cb9 short i/o: fix calls to read to use xread or read_in_full
We have a number of badly checked read() calls.  Often we are
expecting read() to read exactly the size we requested or fail, this
fails to handle interrupts or short reads.  Add a read_in_full()
providing those semantics.  Otherwise we at a minimum need to check
for EINTR and EAGAIN, where this is appropriate use xread().

4d06f8ac43 Fix 'git add' with .gitignore
When '*.ig' is ignored, and you have two files f.ig and d.ig/foo
in the working tree,

	$ git add .

correctly ignored f.ig but failed to ignore d.ig/foo.  This was
caused by a thinko in an earlier commit 4888c534, when we tried
to allow adding otherwise ignored files.

After reverting that commit, this takes a much simpler approach.
When we have an unmatched pathspec that talks about an existing
pathname, we know it is an ignored path the user tried to add,
so we include it in the set of paths directory walker returned.

This does not let you say "git add -f D" on an ignored directory
D and add everything under D.  People can submit a patch to
further allow it if they want to, but I think it is a saner
behaviour to require explicit paths to be spelled out in such a
case.

e813d50e35 match_pathspec() -- return how well the spec matched
This updates the return value from match_pathspec() so that the
caller can tell cases between exact match, leading pathname
match (i.e. file "foo/bar" matches a pathspec "foo"), or
filename glob match.  This can be used to prevent "rm dir" from
removing "dir/file" without explicitly asking for recursive
behaviour with -r flag, for example.

85023577a8 simplify inclusion of system header files.
This is a mechanical clean-up of the way *.c files include
system header files.

 (1) sources under compat/, platform sha-1 implementations, and
     xdelta code are exempt from the following rules;

 (2) the first #include must be "git-compat-util.h" or one of
     our own header file that includes it first (e.g. config.h,
     builtin.h, pkt-line.h);

 (3) system headers that are included in "git-compat-util.h"
     need not be included in individual C source files.

 (4) "git-compat-util.h" does not have to include subsystem
     specific header files (e.g. expat.h).

f8a9d42872 read-tree: further loosen "working file will be lost" check.
This follows up commit ed93b449 where we removed overcautious
"working file will be lost" check.

A new option "--exclude-per-directory=.gitignore" can be used to
tell the "git-read-tree" command that the user does not mind
losing contents in untracked files in the working tree, if they
need to be overwritten by a merge (either a two-way "switch
branches" merge, or a three-way merge).

c91f0d92ef git-commit.sh: convert run_status to a C builtin
This creates a new git-runstatus which should do roughly the same thing
as the run_status function from git-commit.sh. Except for color support,
the main focus has been to keep the output identical, so that it can be
verified as correct and then used as a C platform for other improvements to
the status printing code.

This doesn't make the code uglier or harder to read, yet it makes the
code more portable.  This also simplifies checking for other potential
incompatibilities.  "gcc -std=c89 -pedantic" can flag many incompatible

This moves the code to add the per-directory ignore files for the base
directory into the library routine.

That not only allows us to turn the function push_exclude_per_directory()
static again, it also simplifies the library interface a lot (the caller
no longer needs to worry about any of the per-directory exclude files at
all).

453ec4bdf4 libify git-ls-files directory traversal
This moves the core directory traversal and filename exclusion logic
into the general git library, making it available for other users
directly.

If we ever want to do "git commit" or "git add" as a built-in (and we
do), we want to be able to handle most of git-ls-files as a library.

NOTE! Not all of git-ls-files is libified by this.  The index matching
and pathspec prefix calculation is still in ls-files.c, but this is a
big part of it.
