A lot of modules that have nothing to do with git-shell functionality

This patch cuts off redundant dependencies by:
1. providing stubs for three functions that make no sense for git-shell;
2. moving quote_path_fully from environment.c to quote.c to make the
later self sufficient;
3. moving make_absolute_path into a new separate file.

So I was looking at the disgusting size of the git binary, and even with
the debugging removed, and using -Os instead of -O2, the size of the text
section was pretty high. In this day and age I guess almost a megabyte of
text isn't really all that surprising, but it still doesn't exactly make
me think "lean and mean".
With -Os, a surprising amount of text space is wasted on inline functions
that end up just being replicated multiple times, and where performance
really isn't a valid reason to inline them. In particular, the trivial
wrapper functions like "xmalloc()" are used _everywhere_, and making them
inline just duplicates the text (and the string we use to 'die()' on
failure) unnecessarily.
So this just moves them into a "wrapper.c" file, getting rid of a tiny bit
of unnecessary bloat. The following numbers are both with "CFLAGS=-Os":
Before:
[torvalds@woody git]$ size git
text data bss dec hex filename
700460 15160 292184 1007804 f60bc git
After:
[torvalds@woody git]$ size git
text data bss dec hex filename
670540 15160 292184 977884 eebdc git
so it saves almost 30k of text-space (it actually saves more than that
with the default -O2, but I don't think that's necessarily a very relevant
number from a "try to shrink git" standpoint).
It might conceivably have a performance impact, but none of this should be
_that_ performance critical. The real cost is not generally in the wrapper
anyway, but in the code it wraps (ie the cost of "xread()" is all in the
read itself, not in the trivial wrapping of it).

This patch adds support to compile and run git on 12 additional platforms.
The platforms are based on UNIX Systems Labs (USL)/Novell/SYS V code base.
The most common are Novell UnixWare 2.X.X, SCO UnixWare 7.X.X,
OpenServer 5.0.X, OpenServer 6.0.X, and SCO pre OSR 5 platforms.
Looking at the the various platform headers, I find:
#if defined(_KERNEL) || !defined(_POSIX_SOURCE) \
&& !defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE)
which hides u_short and other typedefs that other header files on these
platforms depend on. WIth _XOPEN_SOURCE defined, sources that include
system header files that depend on the typedefs such as u_short cannot be
compiled on these platforms.
__USLC__ indicates UNIX System Labs Corperation (USLC), or a Novell-derived
compiler and/or some SysV based OS's.
__M_UNIX indicates XENIX/SCO UNIX/OpenServer 5.0.7 and prior releases
of the SCO OS's. It is used just like Apple and BSD, both of these
shouldn't have _XOPEN_SOURCE defined.

Currently, when looking for a packed object from the pack idx, a
simple binary search is used.
A conventional binary search loop looks like this:
unsigned lo, hi;
do {
unsigned mi = (lo + hi) / 2;
int cmp = "entry pointed at by mi" minus "target";
if (!cmp)
return mi; "mi is the wanted one"
if (cmp > 0)
hi = mi; "mi is larger than target"
else
lo = mi+1; "mi is smaller than target"
} while (lo < hi);
"did not find what we wanted"
The invariants are:
- When entering the loop, 'lo' points at a slot that is never
above the target (it could be at the target), 'hi' points at
a slot that is guaranteed to be above the target (it can
never be at the target).
- We find a point 'mi' between 'lo' and 'hi' ('mi' could be
the same as 'lo', but never can be as high as 'hi'), and
check if 'mi' hits the target. There are three cases:
- if it is a hit, we have found what we are looking for;
- if it is strictly higher than the target, we set it to
'hi', and repeat the search.
- if it is strictly lower than the target, we update 'lo'
to one slot after it, because we allow 'lo' to be at the
target and 'mi' is known to be below the target.
If the loop exits, there is no matching entry.
When choosing 'mi', we do not have to take the "middle" but
anywhere in between 'lo' and 'hi', as long as lo <= mi < hi is
satisfied. When we somehow know that the distance between the
target and 'lo' is much shorter than the target and 'hi', we
could pick 'mi' that is much closer to 'lo' than (hi+lo)/2,
which a conventional binary search would pick.
This patch takes advantage of the fact that the SHA-1 is a good
hash function, and as long as there are enough entries in the
table, we can expect uniform distribution. An entry that begins
with for example "deadbeef..." is much likely to appear much
later than in the midway of a reasonably populated table. In
fact, it can be expected to be near 87% (222/256) from the top
of the table.
This is a work-in-progress and has switches to allow easier
experiments and debugging. Exporting GIT_USE_LOOKUP environment
variable enables this code.
On my admittedly memory starved machine, with a partial KDE
repository (3.0G pack with 95M idx):
$ GIT_USE_LOOKUP=t git log -800 --stat HEAD >/dev/null
3.93user 0.16system 0:04.09elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k

It's really totally separate functionality, and if we want to start
doing case-insensitive hash lookups, I'd rather do it when it's
separated out.
It also renames "remove_index_entry()" to "remove_name_hash()", because
that really describes the thing better. It doesn't actually remove the
index entry, that's done by "remove_index_entry_at()", which is something
very different, despite the similarity in names.

To support both at runtime, this commit introduces GITWEB_CONFIG_SYSTEM as

The top-level Makefile now creates a GIT-BUILD-OPTIONS file
which stores any options selected by the make process that
may be of use to further parts of the build process.
Specifically, we store the SHELL_PATH so that it can be used
by tests to construct shell scripts on the fly.
The format of the GIT-BUILD-OPTIONS file is Bourne shell,
and it is sourced by test-lib.sh; all tests can rely on just
having $SHELL_PATH correctly set in the environment.
The GIT-BUILD-OPTIONS file is written every time the
toplevel 'make' is invoked. Since the only users right now
are the test scripts, there's no drawback to updating its
timestamp. If something build-related depends on this, we
can do a trick similar to the one used by GIT-CFLAGS.

Packing objects can be done in parallell nowadays, but it's
only done if the config option pack.threads is set to a value
above 1. Because of that, the code-path used is often not the
most optimal one.
This patch adds a routine to detect the number of online CPU's
at runtime (online_cpus()). When pack.threads (or --threads=) is
given a value of 0, the number of threads is set to the number of
online CPU's. This feature is also documented.
As per Nicolas Pitre's recommendations, the default is still to
run pack-objects single-threaded unless explicitly activated,
either by configuration or by command line parameter.
The routine online_cpus() is a rework of "numcpus.c", written by
one Philip Willoughby <pgw99@doc.ic.ac.uk>. numcpus.c is in the

The only differences in behavior should be:
- git checkout -m with non-trivial merging won't print out
merge-recursive messages (see the change in t7201-co.sh)
- git checkout -- paths... will give a sensible error message if
HEAD is invalid as a commit.
- some intermediate states which were written to disk in the shell
version (in particular, index states) are only kept in memory in
this version, and therefore these can no longer be revealed by
later write operations becoming impossible.
- when we change branches, we discard MERGE_MSG, SQUASH_MSG, and
rr-cache/MERGE_RR, like reset always has.
I'm not 100% sure I got the merge recursive setup exactly right; the
base for a non-trivial merge in the shell code doesn't seem
theoretically justified to me, but I tried to match it anyway, and the
tests all pass this way.
Other than these items, the results should be identical to the shell
version, so far as I can tell.

This makes write_tree_from_memory(), which writes the active cache as
a tree and returns the struct tree for it, available to other code. It
also makes available merge_trees(), which does the internal merge of
two trees with a known base, and merge_recursive(), which does the
recursive internal merge of two commits with a list of common
ancestors.
The first two of these will be used by checkout -m, and the third is
presumably useful in general, although the implementation of checkout
-m which entirely matches the behavior of the shell version does not
use it (since it ignores the difference of ancestry between the old
branch and the new branch).

qsort in Windows 2000 (and various other C libraries) is a Quicksort
with the usual O(n^2) worst case. Unfortunately, sorting Git trees
seems to get very close to that worst case quite often:
$ /git/gitbad runstatus
# On branch master
qsort, nmemb = 30842
done, 237838087 comparisons.
This patch adds a simplified version of the merge sort that is glibc's
qsort(3). As a merge sort, this needs a temporary array equal in size
to the array that is to be sorted, but has a worst-case performance of
O(n log n).
The complexity that was removed is:
* Doing direct stores for word-size and -aligned data.
* Falling back to quicksort if the allocation required to perform the
merge sort would likely push the machine into swap.
Even with these simplifications, this seems to outperform the Windows
qsort(3) implementation, even in Windows XP (where it is "fixed" and
doesn't trigger O(n^2) complexity on trees).
[jes: moved into compat/qsort.c, as per Johannes Sixt's suggestion]
[bcd: removed gcc-ism, thanks to Edgar Toernig. renamed make variable
per Junio's comment.]

"git-help--browse" helper is to launch a browser of the user's choice
to view the HTML version of git documentation for a given command. It
used to take the name of a command, convert it to the path of the
documentation by prefixing the directory name and appending the
".html" suffix, and start the browser on the path.
This updates the division of labor between the caller in help.c and
git-help--browser helper. The helper is now responsible for launching
a browser of the user's choice on given URLs, and it is the caller's
responsibility to tell it the paths to documentation files.
This is in preparation to reuse the logic to choose user's preferred
browser in instaweb.
The helper had a provision for running it without any command name, in
which case it showed the toplevel "git(7)" documentation, but the
caller in help.c never makes such a call. The helper now exits with a
usage message when no path is given.

POSIX.1-2001 has declaration of select(2) in <sys/select.h>, but
in the previous version of SUS, it was declared in <sys/time.h>
(which is already included in git-compat-util.h).
This introduces NO_SYS_SELECT_H macro in the Makefile to be set
on older systems, to skip inclusion of <sys/select.h> that does
not exist on them.
We could check _POSIX_VERSION with 200112L and do this
automatically, but earlier it was reported that the approach
does not work well on some vintage of HP-UX. Other systems may
get _POSIX_VERSION itself wrong. At least for now, this manual

The `core.whitespace` configuration variable allows you to define what
`diff` and `apply` should consider whitespace errors for all paths in
the project (See gitlink:git-config[1]). This attribute gives you finer
control per path.
For example, if you have these in the .gitattributes:
frotz whitespace
nitfol -whitespace
xyzzy whitespace=-trailing
all types of whitespace problems known to git are noticed in path 'frotz'
(i.e. diff shows them in diff.whitespace color, and apply warns about
them), no whitespace problem is noticed in path 'nitfol', and the
default types of whitespace problems except "trailing whitespace" are
noticed for path 'xyzzy'. A project with mixed Python and C might want
to have:
*.c whitespace
*.py whitespace=-indent-with-non-tab
in its toplevel .gitattributes file.

This replaces git-clean.sh with builtin-clean.c, and moves
git-clean.sh to the examples.
This also introduces a change in behavior when removing directories
explicitly specified as a path. For example currently:
1. When dir has only untracked files, these two behave differently:
$ git clean -n dir
$ git clean -n dir/
the former says "Would not remove dir/", while the latter would say
"Would remove dir/untracked" for all paths under it, but not the
directory itself.
With -d, the former would stop refusing, however since the user
explicitly asked to remove the directory the -d is no longer required.
2. When there are more parameters:
$ git clean -n dir foo
$ git clean -n dir/ foo
both cases refuse to remove dir/ unless -d is specified. Once again
since both cases requested to remove dir the -d is no longer required.

The option parser takes argc, argv, an array of struct option
and a usage string. Each of the struct option elements in the array
describes a valid option, its type and a pointer to the location where the
value is written. The entry point is parse_options(), which scans through
the given argv, and matches each option there against the list of valid
options. During the scan, argv is rewritten to only contain the
non-option command line arguments and the number of these is returned.
Aggregation of single switches is allowed:
-rC0 is the same as -r -C 0 (supposing that -C wants an arg).
Every long option automatically support the option with the same name,
prefixed with 'no-' to unset the switch. It assumes that initial value for
strings are "NULL" and for integers is "0".
Long options are supported either with '=' or without:
--some-option=foo is the same as --some-option foo

This implements a smarter rename detector for exact renames, which
rather than doing a pairwise comparison (time O(m*n)) will just hash the
files into a hash-table (size O(n+m)), and only do pairwise comparisons
to renames that have the same hash (time O(n+m) except for unrealistic
hash collissions, which we just cull aggressively).
Admittedly the exact rename case is not nearly as interesting as the
generic case, but it's an important case none-the-less. A similar general
approach should work for the generic case too, but even then you do need
to handle the exact renames/copies separately (to avoid the inevitable
added cost factor that comes from the _size_ of the file), so this is
worth doing.
In the expectation that we will indeed do the same hashing trick for the
general rename case, this code uses a generic hash-table implementation
that can be used for other things too. In fact, we might be able to
consolidate some of our existing hash tables with the new generic code
in hash.[ch].

Thanks to Johannes Schindelin for review and fixes, and Julian
Phillips for the original C translation.
This changes a few small bits of behavior:
branch.<name>.merge is parsed as if it were the lhs of a fetch
refspec, and does not have to exactly match the actual lhs of a
refspec, so long as it is a valid abbreviation for the same ref.
branch.<name>.merge is no longer ignored if the remote is configured
with a branches/* file. Neither behavior is useful, because there can
only be one ref that gets fetched, but this is more consistant.
Also, fetch prints different information to standard out.

Add tests for documented features of "git reset".

gets selected paths into the index.
The reset option with paths was implemented by Johannes Schindelin.
Since the option that gets selected paths into the index is not
a "reset" like the others because it does not change the HEAD at all,
now the command is showing a warning when the "--mixed" option
is supplied for that purpose.
The following table shows the behaviour of "git reset" for
the different supported options, where X means "changing"
the HEAD, index or working tree:

This replaces "git-verify-tag.sh" with "builtin-verify-tag.c".
Testing relies on the "git tag -v" tests calling this command.
A temporary file is needed when calling to gpg, because git is
already creating detached signatures (gpg option -b) to sign tags
(instead of leaving gpg to add the signature to the file by itself),
and those signatures need to be supplied in a separate file to be
verified by gpg.
The program uses git_mkstemp to create that temporary file needed by
gpg, instead of the previously used "$GIT_DIR/.tmp-vtag", in order to
allow the command to be used in read-only repositories, and also
prevent other instances of git to read or remove the same file.
Signal SIGPIPE is ignored because the program sometimes was
terminated because that signal when writing the input for gpg.
The command now can receive many tag names to be verified.

"git tag" with no arguments prints all tags, more like "git branch" does,
and "git tag -n" also prints all tags with annotations (without needing -l).

- It failed to replace git$X with git.o in the list of files that
record GIT_VERSION. This broke incorporation of a changed
GIT_VERSION into git$X because, when GIT_VERSION changes, git.o isn't
remade and git$X is relinked from the git.o that still contains the
old GIT_VERSION.

I realize that a lot of people use the "git-xyzzy" format, and we have
various historical reasons for it, but I also think that most people have
long since started thinking of the git command as a single command with
various subcommands, and we've long had the documentation talk about it
that way.
Slowly migrating away from the git-xyzzy format would allow us to
eventually no longer install hundreds of binaries (even if most of them
are symlinks or hardlinks) in users $PATH, and the _original_ reasons for
it (implementation issues and bash completion) are really long long gone.
Using "git xyzzy" also has some fundamental advantages, like the ability
to specify things like paging ("git -p xyzzy") and making the whole notion
of aliases act like other git commands (which they already do, but they do
*not* have a "git-xyzzy" form!)
Anyway, while actually removing the "git-xyzzy" things is not practical
right now, we can certainly start slowly to deprecate it internally inside
git itself - in the shell scripts we use, and the test vectors.
This patch adds a "remove-dashes" makefile target, which does that. It
isn't particularly efficient or smart, but it *does* successfully rewrite
a lot of our shell scripts to use the "git xyzzy" form for all built-in
commands.
(For non-builtins, the "git xyzzy" format implies an extra execve(), so
this script leaves those alone).
So apply this patch, and then run
make remove-dashes
make test
git commit -a
to generate a much larger patch that actually starts this transformation.
(The only half-way subtle thing about this is that it also fixes up
git-filter-branch.sh for the new world order by adding quoting around
the use of "git-commit-tree" as an argument. It doesn't need it in that
format, but when changed into "git commit-tree" it is no longer a single
word, and the quoting maintains the old behaviour).
NOTE! This does not yet mean that you can actually stop installing the
"git-xyzzy" binaries for the builtins. There are some remaining places
that want to use the old form, this just removes the most obvious ones
that can easily be done automatically.

Don't you just hate the fact sometimes, that git-rebase just applies
the patches, without any possibility to edit them, or rearrange them?
With "--interactive", git-rebase now lets you edit the list of patches,
so that you can reorder, edit and delete patches.
Such a list will typically look like this:
pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...
By replacing the command "pick" with the command "edit", you can amend
that patch and/or its commit message, and by replacing it with "squash"
you can tell rebase to fold that patch into the patch before that.

This command can be used to initialize, update and inspect submodules. It
uses a .gitmodules file, readable by git-config, in the top level directory
of the 'superproject' to specify a mapping between submodule paths and
repository url.
Example .gitmodules layout:
[module "git"]
url = git://git.kernel.org/pub/scm/git/git.git
With this entry in .gitmodules (and a commit reference in the index entry for
the path "git"), the command 'git submodule init' will clone the repository
at kernel.org into the directory "git".

There is currently no way to override the url found in the .gitmodules file,
except by manually creating the subproject repository. The place to fix this

HPA noticed that git-rebase fails when changes involve symlinks
in the middle of the hierarchy. Consider:
* The tree state before the patch is applied has arch/x86_64/boot
as a symlink pointing at ../i386/boot/
* The patch tries to remove arch/x86_64/boot symlink, and
create bunch of files there: .gitignore, Makefile, etc.
git-apply tries to be careful while applying patches; it never
touches the working tree until it is convinced that the patch
would apply cleanly. One of the check it does is that when it
knows a path is going to be created by the patch, it runs
lstat() on the path to make sure it does not exist.
This leads to a false alarm. Because we do not touch the
working tree before all the check passes, when we try to make
sure that arch/x86_64/boot/.gitignore does not exist yet, we
haven't removed the arch/x86_64/boot symlink. The lstat() check
ends up seeing arch/i386/boot/.gitignore through the
yet-to-be-removed symlink, and says "Hey, you already have a
file there, but what you fed me is a patch to create a new
file. I am not going to clobber what you have in the working
tree."
We have similar checks to see a file we are going to modify does
exist and match the preimage of the diff, which is done by
directly opening and reading the file.
For a file we are going to delete, we make sure that it does
exist and matches what is going to be removed (a removal patch
records the full preimage, so we check what you have in your
working tree matches it in full -- otherwise we would risk
losing your local changes), which again is done by directly
opening and reading the file.
These checks need to be adjusted so that they are not fooled by
symlinks in the middle.
- To make sure something does not exist, first lstat(). If it
does not exist, it does not, so be happy. If it _does_, we
might be getting fooled by a symlink in the middle, so break
leading paths and see if there are symlinks involved. When
we are checking for a path a/b/c/d, if any of a, a/b, a/b/c
is a symlink, then a/b/c/d does _NOT_ exist, for the purpose
of our test.
This would fix this particular case you saw, and would not
add extra overhead in the usual case.
- To make sure something already exists, first lstat(). If it
does not exist, barf (up to this, we already do). Even if it
does seem to exist, we might be getting fooled by a symlink
in the middle, so make sure leading paths are not symlinks.
This would make the normal codepath much more expensive for
deep trees, which is a bit worrisome.
This patch implements the first side of the check "making sure
it does not exist". The latter "making sure it exists" check is
not done yet, so applying the patch in reverse would still
fail, but we have to start from somewhere.

I'm finding it difficult to work with a 6,000+ line Tcl script
and not go insane while looking for a particular block of code.
Since most of the program is organized into different units of
functionality and not all users will need all units immediately
on startup we can improve things by splitting procs out into
multiple files and let auto_load handle things for us.
This should help not only to better organize the source, but
it may also improve startup times for some users as the Tcl
parser does not need to read as much script before it can show
the UI. In many cases the user can avoid reading at least half
of git-gui now.
Unfortunately we now need a library directory in our runtime
location. This is currently assumed to be $(sharedir)/git-gui/lib
and its expected that the Makefile invoker will setup some sort of
reasonable sharedir value for us, or let us assume its going to be
$(gitexecdir)/../share.
We now also require a tclsh (in TCL_PATH) to just run the Makefile,
as we use tclsh to generate the tclIndex for our lib directory. I'm
hoping this is not an unncessary burden on end-users who are building

I haven't really made any functionality changes here, this is just a

Like core-Git we now track the values that we embed into our shell
script wrapper, and we "recompile" that wrapper if they are changed.
This concept was lifted from git.git's Makefile, where a similar
thing was done by Eygene Ryabinkin. Too bad it wasn't just done
here in git-gui from the beginning, as the git.git Makefile support
for GIT-GUI-VARS was really just because git-gui doesn't do it on

Remove usernames from all commit messages, not just when using svmprops

Create a sysconfdir variable, and use it for ETC_GITCONFIG
ETC_GITCONFIG defaults to $(prefix)/etc/gitconfig, so if you just set
prefix=/usr, you end up with a git that looks in /usr/etc/gitconfig, rather
than /etc/gitconfig as specified by the FHS. Furthermore, setting
ETC_GITCONFIG does not fix the paths to any future system-wide configuration
files.
Factor out the path to the system-wide configuration directory into a variable
sysconfdir, normally set to $(prefix)/etc, but set to /etc when prefix=/usr .
This fixes the prefix=/usr problem for ETC_GITCONFIG, and allows centralized
configuration of any future system-wide configuration files without requiring
further action from package maintainers or other people building and
installing git.

This adds the basic infrastructure to assign attributes to
paths, in a way similar to what the exclusion mechanism does
based on $GIT_DIR/info/exclude and .gitignore files.
An attribute is just a simple string that does not contain any
whitespace. They can be specified in $GIT_DIR/info/attributes
file, and .gitattributes file in each directory.
Each line in these files defines a pattern matching rule.
Similar to the exclusion mechanism, a later match overrides an
earlier match in the same file, and entries from .gitattributes
file in the same directory takes precedence over the ones from
parent directories. Lines in $GIT_DIR/info/attributes file are
used as the lowest precedence default rules.
A line is either a comment (an empty line, or a line that begins
with a '#'), or a rule, which is a whitespace separated list of
tokens. The first token on the line is a shell glob pattern.
The rest are names of attributes, each of which can optionally
be prefixed with '!'. Such a line means "if a path matches this
glob, this attribute is set (or unset -- if the attribute name
is prefixed with '!'). For glob matching, the same "if the
pattern does not have a slash in it, the basename of the path is
matched with fnmatch(3) against the pattern, otherwise, the path
is matched with the pattern with FNM_PATHNAME" rule as the
exclusion mechanism is used.
This does not define what an attribute means. Tying an
attribute to various effects it has on git operation for paths
that have it will be specified separately.

This merge strategy largely piggy-backs on git-merge-recursive.
When merging trees A and B, if B corresponds to a subtree of A,
B is first adjusted to match the tree structure of A, instead of
reading the trees at the same level. This adjustment is also
done to the common ancestor tree.
If you are pulling updates from git-gui repository into git.git
repository, the root level of the former corresponds to git-gui/
subdirectory of the latter. The tree object of git-gui's toplevel
is wrapped in a fake tree object, whose sole entry has name 'git-gui'
and records object name of the true tree, before being used by
the 3-way merge code.
If you are merging the other way, only the git-gui/ subtree of
git.git is extracted and merged into git-gui's toplevel.
The detection of corresponding subtree is done by comparing the
pathnames and types in the toplevel of the tree.
Heuristics galore! That's the git way ;-).

Some workflows require use of repositories on machines that cannot be
connected, preventing use of git-fetch / git-push to transport objects and
references between the repositories.
git-bundle provides an alternate transport mechanism, effectively allowing
git-fetch and git-pull to operate using sneakernet transport. `git-bundle
create` allows the user to create a bundle containing one or more branches
or tags, but with specified basis assumed to exist on the target
repository. At the receiving end, git-bundle acts like git-fetch-pack,
allowing the user to invoke git-fetch or git-pull using the bundle file as
the URL. git-fetch and git-ls-remote determine they have a bundle URL by
checking that the URL points to a file, but are otherwise unchanged in
operation with bundles.
The original patch was done by Mark Levedahl <mdl123@verizon.net>.
It was updated to make git-bundle a builtin, and get rid of the tar
format: now, the first line is supposed to say "# v2 git bundle", the next
lines either contain a prerequisite ("-" followed by the hash of the
needed commit), or a ref (the hash of a commit, followed by the name of
the ref), and finally the pack. As a result, the bundle argument can be
"-" now.

It currently does NOT know about file attributes, so it does its
conversion purely based on content. Maybe that is more in the "git
philosophy" anyway, since content is king, but I think we should try to do
the file attributes to turn it off on demand.
Anyway, BY DEFAULT it is off regardless, because it requires a
[core]
AutoCRLF = true
in your config file to be enabled. We could make that the default for
Windows, of course, the same way we do some other things (filemode etc).
But you can actually enable it on UNIX, and it will cause:
- "git update-index" will write blobs without CRLF
- "git diff" will diff working tree files without CRLF
- "git checkout" will write files to the working tree _with_ CRLF
and things work fine.
Funnily, it actually shows an odd file in git itself:
git clone -n git test-crlf
cd test-crlf
git config core.autocrlf true
git checkout
git diff
shows a diff for "Documentation/docbook-xsl.css". Why? Because we have
actually checked in that file *with* CRLF! So when "core.autocrlf" is
true, we'll always generate a *different* hash for it in the index,
because the index hash will be for the content _without_ CRLF.
Is this complete? I dunno. It seems to work for me. It doesn't use the
filename at all right now, and that's probably a deficiency (we could
certainly make the "is_binary()" heuristics also take standard filename
heuristics into account).
I don't pass in the filename at all for the "index_fd()" case
(git-update-index), so that would need to be passed around, but this
actually works fine.
NOTE NOTE NOTE! The "is_binary()" heuristics are totally made-up by yours
truly. I will not guarantee that they work at all reasonable. Caveat
emptor. But it _is_ simple, and it _is_ safe, since it's all off by
default.
The patch is pretty simple - the biggest part is the new "convert.c" file,
but even that is really just basic stuff that anybody can write in
"Teaching C 101" as a final project for their first class in programming.
Not to say that it's bug-free, of course - but at least we're not talking

git-fast-import requires use of inttypes.h, but the master branch has
added it to git-compat-util differently than git-fast-import originally
had used it. This merge back of master to the fast-import topic is to
get (and use) inttypes.h the way master is using it.
This is a partially evil merge to remove the call to setup_ident(),
as the master branch now contains a change which makes this implicit
and therefore removed the function declaration. (commit 01754769).

I'm stealing the exact logic used by core Git within its own Makefile to

and that the version number also reflects when it is coming from a dirty
working directory (and is thus pretty worthless).

It might be handy to have a single command that helps you manage
your configuration that relates to downloading from remote
repositories. This currently does only about 20% of what I want
it to do.
$ git remote
shows the list of 'remotes' you have defined somewhere, and
$ git remote origin
shows the details about the named remote (in this case
"origin"). How the branches are tracked, if you have a
tracking branch that is stale, etc.
$ git add another git://git.kernel.org/pub/...
defines the default remote.another.url and remote.another.fetch
entries just like a clone does; you can say "git fetch another"
afterwards.
For it to be useful, I think it should be enhanced to:
- check overlaps of tracking branches and warn;
- offer to remove stale tracking branches in one go;
- offer ways to remove or rename remote;
- offer ways to update an existing remote, perhaps have an
interactive mode;
Other enhancements might be also possible, but I do not think of
anything that is absolutely necessary other than the above right
now.

Many users have noticed that core.filemode doesn't appear to be
automatically set right on Cygwin when using a repository stored
on NTFS. The issue is that Cygwin and NTFS correctly supports
the executable mode bit, and Git properly detected that, but most
native Windows applications tend to create files such that Cygwin
sees the executable bit set when it probably shouldn't be.
This is especially bad if the user's favorite editor deletes the
file then recreates it whenever they save (vs. just overwriting)
as now a file that was created with mode 0644 by checkout-index
appears to have mode 0755.
So we introduce NO_TRUSTABLE_FILEMODE, settable at compile time.
Setting this option forces core.filemode to false, even if the
detection code would have returned true. This option should be
enabled by default on Cygwin.

than expire-unreachable time (defaults to 30 days) and records a commit
that has been rewound and made unreachable from the current tip of the
ref are removed from the reflog.

A script to be driven when the user says "git add --interactive"
is introduced.
When it is run, first it runs its internal 'status' command to
show the current status, and then goes into its internactive
command loop.
The command loop shows the list of subcommands available, and
gives a prompt "What now> ". In general, when the prompt ends
with a single '>', you can pick only one of the choices given
and type return, like this:
*** Commands ***
1: status 2: update 3: revert 4: add untracked
5: patch 6: diff 7: quit 8: help
What now> 1
You also could say "s" or "sta" or "status" above as long as the
choice is unique.
The main command loop has 6 subcommands (plus help and quit).
* 'status' shows the change between HEAD and index (i.e. what
will be committed if you say "git commit"), and between index
and working tree files (i.e. what you could stage further
before "git commit" using "git-add") for each path. A sample
output looks like this:
staged unstaged path
1: binary nothing foo.png
2: +403/-35 +1/-1 git-add--interactive.perl
It shows that foo.png has differences from HEAD (but that is
binary so line count cannot be shown) and there is no
difference between indexed copy and the working tree
version (if the working tree version were also different,
'binary' would have been shown in place of 'nothing'). The
other file, git-add--interactive.perl, has 403 lines added
and 35 lines deleted if you commit what is in the index, but
working tree file has further modifications (one addition and
one deletion).
* 'update' shows the status information and gives prompt
"Update>>". When the prompt ends with double '>>', you can
make more than one selection, concatenated with whitespace or
comma. Also you can say ranges. E.g. "2-5 7,9" to choose
2,3,4,5,7,9 from the list. You can say '*' to choose
everything.
What you chose are then highlighted with '*', like this:
staged unstaged path
1: binary nothing foo.png
* 2: +403/-35 +1/-1 git-add--interactive.perl
To remove selection, prefix the input with - like this:
Update>> -2
After making the selection, answer with an empty line to
stage the contents of working tree files for selected paths
in the index.
* 'revert' has a very similar UI to 'update', and the staged
information for selected paths are reverted to that of the
HEAD version. Reverting new paths makes them untracked.
* 'add untracked' has a very similar UI to 'update' and
'revert', and lets you add untracked paths to the index.
* 'patch' lets you choose one path out of 'status' like
selection. After choosing the path, it presents diff between
the index and the working tree file and asks you if you want
to stage the change of each hunk. You can say:
y - add the change from that hunk to index
n - do not add the change from that hunk to index
a - add the change from that hunk and all the rest to index
d - do not the change from that hunk nor any of the rest to index
j - do not decide on this hunk now, and view the next
undecided hunk
J - do not decide on this hunk now, and view the next hunk
k - do not decide on this hunk now, and view the previous
undecided hunk
K - do not decide on this hunk now, and view the previous hunk
After deciding the fate for all hunks, if there is any hunk
that was chosen, the index is updated with the selected hunks.
* 'diff' lets you review what will be committed (i.e. between
HEAD and index).
This is still rough, but does everything except a few things I
think are needed.
* 'patch' should be able to allow splitting a hunk into
multiple hunks.
* 'patch' does not adjust the line offsets @@ -k,l +m,n @@
in the hunk header. This does not have major problem in
practice, but it _should_ do the adjustment.
* It does not have any explicit support for a merge in
progress; it may not work at all.

The Cygwin folks have done a fine job at creating a POSIX layer
on Windows That Just Works(tm). However it comes with a penalty;
accessing files in the working tree by way of stat/open/mmap can
be slower for diffcore than inflating the data from a blob which
is stored in a packfile.
This performance problem is especially an issue in merge-recursive
when dealing with nearly 7000 added files, as we are loading
each file's content from the working directory to perform rename
detection. I have literally seen (and sadly watched) paint dry in
less time than it takes for merge-recursive to finish such a merge.
On the other hand this very same merge runs very fast on Solaris.
If Git is compiled with NO_FAST_WORKING_DIRECTORY set then we will
avoid looking at the working directory when the blob in question
is available within a packfile and the caller doesn't need the data
unpacked into a temporary file.
We don't use loose objects as they have the same open/mmap/close
costs as the working directory file access, but have the additional
CPU overhead of needing to inflate the content before use. So it
is still faster to use the working tree file over the loose object.
If the caller needs the file data unpacked into a temporary file
its likely because they are going to call an external diff program,
passing the file as a parameter. In this case reusing the working
tree file will be faster as we don't need to inflate the data and
write it out to a temporary file.
The NO_FAST_WORKING_DIRECTORY feature is enabled by default on
Cygwin, as that is the platform which currently appears to benefit
the most from this option.

This new function implements the functionality of RCS merge, but
in-memory. It returns < 0 on error, otherwise the number of conflicts.
Finding the conflicting lines can be a very expensive task. You can
control the eagerness of this algorithm:
- a level value of 0 means that all overlapping changes are treated
as conflicts,
- a value of 1 means that if the overlapping changes are identical,
it is not treated as a conflict.
- If you set level to 2, overlapping changes will be analyzed, so that
almost identical changes will not result in huge conflicts. Rather,
only the conflicting lines will be shown inside conflict markers.
With each increasing level, the algorithm gets slower, but more accurate.
Note that the code for level 2 depends on the simple definition of
mmfile_t specific to git, and therefore it will be harder to port that
to LibXDiff.

A shallow commit is a commit which has parents, which in turn are
"grafted away", i.e. the commit appears as if it were a root.
Since these shallow commits should not be edited by the user, but
only by core git, they are recorded in the file $GIT_DIR/shallow.
A repository containing shallow commits is called shallow.
The advantage of a shallow repository is that even if the upstream
contains lots of history, your local (shallow) repository needs not
occupy much disk space.
The disadvantage is that you might miss a merge base when pulling
some remote branch.

This allows web sites with a header and footer standard for each page
to add them to the pages produced by gitweb.
Two new variables $site_header and $site_footer are defined (default
to null) each of which can specify a file containing the header and
footer html.
In addition, if the $stylesheet variable is undefined, a new array
@stylesheets (which defaults to a single element of gitweb.css) can be
used to specify more than one style sheet. This allows the clasical
gitweb.css styles to be retained, but a site wide style sheet used
within the header and footer areas.

This makes three functions and associated option structures from
builtin-grep available from other parts of the system.
* options to drive built-in grep engine is stored in struct
grep_opt;
* pattern strings and extended grep expressions are added to
struct grep_opt with append_grep_pattern();
* when finished calling append_grep_pattern(), call
compile_grep_patterns() to prepare for execution;
* call grep_buffer() to find matches in the in-core buffer.

which suppresses any output from grep_buffer(). Callers of the
function as library can use it to check if there is a match
without producing any output.

This also adds some very rudimentary support for the notion of packed
refs. HOWEVER! At this point it isn't used to actually look up a ref
yet, only for listing them (ie "for_each_ref()" and friends see the
packed refs, but none of the other single-ref lookup routines).
Note how we keep two separate lists: one for the loose refs, and one for
the packed refs we read. That's so that we can easily keep the two apart,
and read only one set or the other (and still always make sure that the
loose refs take precedence).
[ From this, it's not actually obvious why we'd keep the two separate
lists, but it's important to have the packed refs on their own list
later on, when I add support for looking up a single loose one.
For that case, we will want to read _just_ the packed refs in case the
single-ref lookup fails, yet we may end up needing the other list at
some point in the future, so keeping them separated is important ]

This adds a new command, git-for-each-ref. You can have it iterate
over refs and have it output various aspects of the objects they
refer to.
Signed-off-by: Junio C Hamano <junkio@cox.net>
It's kind of like "git peek-remote", but works only locally (and thus
avoids the whole overhead of git_connect()) and has some extra
verification features.
For example, it allows you to filter the results, and to choose whether
you want the tag dereferencing or not. You can also use it to just test
whether a particular ref exists.
For example:
git show-ref master
will show all references called "master", whether tags or heads or
anything else, and regardless of how deep in the reference naming
hierarchy they are (so it would show "refs/heads/master" but also
"refs/remote/other-repo/master").
When using the "--verify" flag, the command requires an exact ref path:
git show-ref --verify refs/heads/master
will only match the exact branch called "master".
If nothing matches, show-ref will return an error code of 1, and in the
case of verification, it will show an error message.
For scripting, you can ask it to be quiet with the "--quiet" flag, which
allows you to do things like
git-show-ref --quiet --verify -- "refs/heads/$headname" ||
echo "$headname is not a valid branch"
to check whether a particular branch exists or not (notice how we don't
actually want to show any results, and we want to use the full refname for
it in order to not trigger the problem with ambiguous partial matches).
To show only tags, or only proper branch heads, use "--tags" and/or
"--heads" respectively (using both means that it shows tags _and_ heads,
but not other random references under the refs/ subdirectory).
To do automatic tag object dereferencing, use the "-d" or "--dereference"
flag, so you can do
git show-ref --tags --dereference
to get a listing of all tags together with what they dereference.

This command implements the git archive protocol on the server
side. This command is not intended to be used by the end user.
Underlying git-archive command line options are sent over the
protocol from "git-archive --remote=...", just like upload-tar
currently does with "git-tar-tree=...".
As for "git-archive" command implementation, this new command
does not execute any existing "git-{tar,zip}-tree" but rely
on the archive API defined by "git-archive" patch. Hence we
get 2 good points:
- "git-archive" and "git-upload-archive" share all option
parsing code.
- All kind of git-upload-{tar,zip} can be deprecated.

git-archive is a command to make TAR and ZIP archives of a git tree.
It helps prevent a proliferation of git-{format}-tree commands.
Instead of directly calling git-{tar,zip}-tree command, it defines
a very simple API, that archiver should implement and register in
"git-archive.c". This API is made up by 2 functions whose prototype
is defined in "archive.h" file.
- The first one is used to parse 'extra' parameters which have
signification only for the specific archiver. That would allow
different archive backends to have different kind of options.
- The second one is used to ask to an archive backend to build
the archive given some already resolved parameters.
The main reason for making this API is to avoid using
git-{tar,zip}-tree commands, hence making them useless. Maybe it's
time for them to die ?
It also implements remote operations by defining a very simple
protocol: it first sends the name of the specific uploader followed
the repository name (git-upload-tar git://example.org/repo.git).
Then it sends options. It's done by sending a sequence of one
argument per packet, with prefix "argument ", followed by a flush.
The remote protocol is implemented in "git-archive.c" for client
side and is triggered by "--remote=<repo>" option. For example,
to fetch a TAR archive in a remote repo, you can issue:
$ git archive --format=tar --remote=git://xxx/yyy/zzz.git HEAD
We choose to not make a new command "git-fetch-archive" for example,
avoind one more GIT command which should be nice for users (less
commands to remember, keeps existing --remote option).

The little helper write_or_die() won't come back with bad news about
full disks or broken pipes. It either succeeds or terminates the
program, making additional error handling unnecessary.
This patch adds the new function and uses it to replace two similar
ones (the one in tar-tree originally has been copied from cat-file
btw.). I chose to add the fd parameter which both lacked to make
write_or_die() just as flexible as write() and thus suitable for
lib-ification.
There is a regression: error messages emitted by this function don't
show the program name, while the replaced two functions did. That's

This is just an update for people being interested. Alex and me were
busy with that project for a few days now. While it has progressed nicely,
there are quite a couple TODOs in merge-recursive.c, just search for "TODO".
For impatient people: yes, it passes all the tests, and yes, according
to the evil test Alex did, it is faster than the Python script.
But no, it is not yet finished. Biggest points are:
- there are still three external calls
- in the end, it should not be necessary to write the index more than once
(just before exiting)
- a lot of things can be refactored to make the code easier and shorter
BTW we cannot just plug in git-merge-tree yet, because git-merge-tree
does not handle renames at all.
This patch is meant for testing, and as such,
- it compile the program to git-merge-recur
- it adjusts the scripts and tests to use git-merge-recur instead of
git-merge-recursive
- it provides "TEST", a script to execute the tests regarding -recursive
- it inlines the changes to read-cache.c (read_cache_from(), discard_cache()
and refresh_cache_entry())

This patch introduces a very basic and barebone Git.pm module
with a sketch of how the generic interface would look like;
most functions are missing, but this should give some good base.
I will continue expanding it.
Most desirable now is more careful error reporting, generic_in() for feeding
input to Git commands and the repository() constructor doing some poking
with git-rev-parse to get the git directory and subdirectory prefix.
Those three are basically the prerequisities for converting git-mv.
I will send them as follow-ups to this patch.
Currently Git.pm just wraps up exec()s of Git commands, but even that
is not trivial to get right and various Git perl scripts do it in
various inconsistent ways. In addition to Git.pm, there is now also
Git.xs which provides barebone Git.xs for directly interfacing with
libgit.a, and as an example providing the hash_object() function using
libgit.
This adds the Git module, integrates it to the build system and as
an example converts the git-fmt-merge-msg.perl script to it (the result
is not very impressive since its advantage is not quite apparent in this
one, but I just picked up the simplest Git user around).
Compared to v3, only very minor things were fixed in this patch (some
whitespaces, a missing export, tiny bug in git-fmt-merge-msg.perl);
at first I wanted to post them as a separate patch but since this
is still only in pu, I decided that it will be cleaner to just resend

This fleshes out the code that generates a three-way merge of a set of
blobs.
It still actually does the three-way merge using an external executable
(ie just calling "merge"), but the interfaces have been cleaned up a lot
and are now fully based on the 'mmfile_t' interface, so if libxdiff were
to ever grow a compatible three-way-merge, it could probably be directly
plugged in.
It also uses the previous XDL_EMIT_COMMON functionality extension to
libxdiff to generate a made-up base file for the merge for the case where
no base file previously existed. This should be equivalent to what we
currently do in git-merge-one-file.sh:
diff -u -La/$orig -Lb/$orig $orig $src2 | git-apply --no-add
except it should be much simpler and can be done using the direct libxdiff
interfaces.

This creates a simple specialized object allocator for basic
objects.
This avoids wasting space with malloc overhead (metadata and
extra alignment), since the specialized allocator knows the
alignment, and that objects, once allocated, are never freed.
It also allows us to track some basic statistics about object
allocations. For example, for the mozilla import, it shows
object usage as follows:
blobs: 627629 (14710 kB)
trees: 1119035 (34969 kB)
commits: 196423 (8440 kB)
tags: 1336 (46 kB)
and the simpler allocator shaves off about 2.5% off the memory
footprint off a "git-rev-list --all --objects", and is a bit
faster too.
[ Side note: this concludes the series of "save memory in object storage".
The thing is, there simply isn't much more to be saved on the objects.
Doing "git-rev-list --all --objects" on the mozilla archive has a final
total RSS of 131498 pages for me: that's about 513MB. Of that, the
object overhead is now just 56MB, the rest is going somewhere else (put
another way: the fact that this patch shaves off 2.5% of the total
memory overhead, considering that objects are now not much more than 10%
of the total shows how big the wasted space really was: this makes
object allocations much more memory- and time-efficient).
I haven't looked at where the rest is, but I suspect the bulk of it is
just the pack-file loading. It may be that we should pack the tree
objects separately from the blob objects: for git-rev-list --objects, we
don't actually ever need to even look at the blobs, but since trees and
blobs are interspersed in the pack-file, we end up not being dense in
the tree accesses, so we end up looking at more pages than we strictly
need to.
So with a 535MB pack-file, it's entirely possible - even likely - that
most of the remaining RSS is just the mmap of the pack-file itself. We
don't need to map in _all_ of it, but we do end up mapping a fair
amount. ]

This shrinks "struct object" to the absolutely minimal size possible.
It now contains /only/ the object flags and the SHA1 hash name of the
object.
The "refs" field, which is really needed only for fsck, is maintained in
a separate hashed lookup-table, allowing all normal users to totally
ignore it.
This helps memory usage, although not as much as I hoped: it looks like
the allocation overhead of malloc (and the alignment constraints in
particular) means that while the structure size shrinks, the actual
allocation overhead mostly does not.
[ That said: memory usage is actually down, but not as much as it should
be: I suspect just one of the object types actually ended up shrinking
its effective allocation size.
To get to the next level, we probably need specialized allocators that
don't pad the allocation more than necessary. ]
The separation makes for some code cleanup, though, and makes the ref
tracking that fsck wants a clearly separate thing.

This changes semantics very subtly, because it adds a new atomicity
guarantee.
In particular, if you "git rm" several files, it will now do all or
nothing. The old shell-script really looped over the removed files one by
one, and would basically randomly fail in the middle if "-f" was used and
one of the files didn't exist in the working directory.
This C builtin one will not re-write the index after each remove, but
instead remove all files at once. However, that means that if "-f" is used
(to also force removal of the file from the working directory), and some
files have already been removed from the workspace, it won't stop in the
middle in some half-way state like the old one did.
So what happens is that if the _first_ file fails to be removed with "-f",
we abort the whole "git rm". But once we've started removing, we don't
leave anything half done. If some of the other files don't exist, we'll
just ignore errors of removal from the working tree.
This is only an issue with "-f", of course.
I think the new behaviour is strictly an improvement, but perhaps more
importantly, it is _different_. As a special case, the semantics are
identical for the single-file case (which is the only one our test-suite
seems to test).
The other question is what to do with leading directories. The old "git

Importing a quilt patch series into git is not very difficult
but parsing the patch descriptions and all of the other
minutia take a bit of effort to get right, so this automates it.
Since git and quilt complement each other it makes sense
to make it easy to go back and forth between the two.
If a patch is encountered that it cannot derive the author

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.

* np/delta:
improve diff-delta with sparse and/or repetitive data
tiny optimization to diff-delta
replace adler32 with Rabin's polynomial in diff-delta
use delta index data when finding best delta matches
split the diff-delta interface
This adds "binary patch" to the diff output and teaches apply
what to do with them.
On the diff generation side, traditionally, we said "Binary
files differ\n" without giving anything other than the preimage
and postimage object name on the index line. This was good
enough for applying a patch generated from your own repository
(very useful while rebasing), because the postimage would be
available in such a case. However, this was not useful when the
recipient of such a patch via e-mail were to apply it, even if
the preimage was available.
This patch allows the diff to generate "binary" patch when
operating under --full-index option. The binary patch follows
the usual extended git diff headers, and looks like this:
"GIT binary patch\n"
<length byte><data>"\n"
...
"\n"
Each line is prefixed with a "length-byte", whose value is upper
or lowercase alphabet that encodes number of bytes that the data
on the line decodes to (1..52 -- 'A' means 1, 'B' means 2, ...,
'Z' means 26, 'a' means 27, ...). <data> is 1 or more groups of
5-byte sequence, each of which encodes up to 4 bytes in base85
encoding. Because 52 / 4 * 5 = 65 and we have the length byte,
an output line is capped to 66 characters. The payload is the
same diff-delta as we use in the packfiles.
On the consumption side, git-apply now can decode and apply the
binary patch when --allow-binary-replacement is given, the diff
was generated with --full-index, and the receiving repository
has the preimage blob, which is the same condition as it always
required when accepting an "Binary files differ\n" patch.

This attempts to set up built-in "git grep" to further reduce
our dependence on the shell, while at the same time optionally
allowing to run grep against object database. You could do
funky things like these:
git grep --cached -e pattern ;# grep from index
git grep -e pattern master ;# or in a rev
git grep -e pattern master next ;# or in multiple revs
git grep -e pattern pu^@ ;# even like this with an
;# extension from another topic ;-)
git grep -e pattern master..next ;# or even from rev ranges
git grep -e pattern master~20:Documentation
;# or an arbitrary tree
git grep -e pattern next:git-commit.sh
;# or an arbitrary blob
Right now, it does not understand and/or obey many options grep
should accept, and the pattern must be given with -e option due
to the way the parameter parser is structured, both of which
obviously need to be fixed for usability.
But this is going in the right direction. The shell script
version is one of the worst Portability offender in the git
barebone Porcelainish; it uses xargs -0 to pass paths around and
shell arrays to sift flags and parameters.

This adds a builtin "push" command, which is largely just a C'ification of
the "git-push.sh" script.
Now, the reason I did it as a built-in is partly because it's yet another
step on relying less on shell, but it's actually mostly because I've
wanted to be able to push to _multiple_ repositories, and the most obvious
and simplest interface for that would seem be to just have a "remotes"
file that has multiple URL entries.
(For "pull", having multiple entries should either just select the first
one, or you could fall back on the others on failure - your choice).
And quite frankly, it just became too damn messy to do that in shell.
Besides, we actually have a fair amount of infrastructure in C, so it just
wasn't that hard to do.
Of course, this is almost totally untested. It probably doesn't work for
anything but the one trial I threw at it. "Simple" doesn't necessarily
mean "obviously correct".

Signed-off-by: Junio C Hamano <junkio@cox.net>
The cache_tree data structure is to cache tree object names that
would result from the current index file.
The idea is to have an optional file to record each tree object
name that corresponds to a directory path in the cache when we
run write_cache(), and read it back when we run read_cache().
During various index manupulations, we selectively invalidate
the parts so that the next write-tree can bypass regenerating
tree objects for unchanged parts of the directory hierarchy.
We could perhaps make the cache-tree data an optional part of
the index file, but that would involve the index format updates,
so unless we need it for performance reasons, the current plan
is to use a separate file, $GIT_DIR/index.aux to store this
information and link it with the index file with the checksum
that is already used for index file integrity check.

This is the first installment to libify diff brothers.
The updated diff-files uses revision.c::setup_revisions()
infrastructure to parse its command line arguments, which means
the pathname arguments are checked more strictly than before.
The tests are adjusted to separate possibly missing paths from
the rest of arguments with double-dashes, to show the kosher
way.
As Linus pointed out, renaming diff.c to diff-lib.c was simply
stupid, so I am renaming it back. The new diff-lib.c is to
contain pieces extracted from diff brothers.
