This allows you to do the conversion (although slowly) from
a remote repository, and besides, it's one less thing to worry
about when you don't need to look up the CVS Attic directories
etc.
This mean sthat you can give a beginning/end pair to git-rev-list,
and it will show all entries that are reachable from the beginning
but not the end.
For example
git-rev-list v2.6.12-rc5 v2.6.12-rc4
shows all commits that are in -rc5 but are not in -rc4.
The way broken deletes and creates are shown in the -p
(diff-patch) output format has become consistent with how
rename/copy edits are shown. They will show "dissimilarity
index" value, immediately following the "deleted file mode" and
"new file mode" lines.
The git-apply is taught to grok such an extended header.

A new diffcore filter diffcore-order is introduced. This takes
a text file each of whose line is a shell glob pattern. Patches
that match a glob pattern on an earlier line in the file are
output before patches that match a later line, and patches that
do not match any glob pattern are output last.

Although it was described as such, git-mkdelta didn't really attempt to
find the best delta against any previous object in the list, but was
only able to create a delta against the preceeding object. This patch
reworks the code to fix that limitation and hopefully makes it a bit
clearer than before, including fixing the delta loop detection which was
broken.
This means that
git-mkdelta sha1 sha2 sha3 sha4 sha5 sha6
will now create a sha2 delta against sha1, a sha3 delta against either
sha2 or sha1 and keep the best one, a sha4 delta against either sha3,
sha2 or sha1, etc. The --max-behind argument limits that search for the
best delta to the specified number of previous objects in the list. If
no limit is specified it is unlimited (note: it might run out of
memory with long object lists).
Also added a -q (quiet) switch so it is possible to have 3 levels of
output: -q for nothing, -v for verbose, and if none of -q nor -v is
specified then only actual changes on the object database are shown.
Finally the git-deltafy-script has been updated accordingly, and some
bugs fixed (thanks to Stephen C. Tweedie for spotting them).
This version has been toroughly tested and I think it is ready
for public consumption.

This is meant to make raw git not hugely less usable than something
like raw CVS. I want to make a 1.0 release of the plumbing, and the
actual commit part was just too intimidating.
A new diffcore transformation, diffcore-break.c, is introduced.
When the -B flag is given, a patch that represents a complete
rewrite is broken into a deletion followed by a creation. This
makes it easier to review such a complete rewrite patch.
The -B flag takes the same syntax as the -M and -C flags to
specify the minimum amount of non-source material the resulting
file needs to have to be considered a complete rewrite, and
defaults to 99% if not specified.
As the new test t4008-diff-break-rewrite.sh demonstrates, if a
file is a complete rewrite, it is broken into a delete/create
pair, which can further be subjected to the usual rename
detection if -M or -C is used. For example, if file0 gets
completely rewritten to make it as if it were rather based on
file1 which itself disappeared, the following happens:
The original change looks like this:
file0 --> file0' (quite different from file0)
file1 --> /dev/null
After diffcore-break runs, it would become this:
file0 --> /dev/null
/dev/null --> file0'
file1 --> /dev/null
Then diffcore-rename matches them up:
file1 --> file0'
The internal score values are finer grained now. Earlier
maximum of 10000 has been raised to 60000; there is no user
visible changes but there is no reason to waste available bits.

When preparing data to feed the external diff, we should give
the mode we obtained from the caller, even when we are dealing
with a file with 0{40} SHA1 (i.e. the caller said "look at the
filesystem"), since the mode passed by the caller via
diff_addremove() or diff_change() is always trustworthy.
This is _not_ a bugfix --- the existing code stat() on the file
ifself and does the same computation on st.st_mode to compute
the mode the same way the caller did to give the original mode.
We cannot remove the stat() call from here, but the extra
computation to create the mode value is unnecessary.

The score number that follow R/C status were parsed but the
parse pointer was not updated, causing the entire line to become
unrecognized. This patch fixes this problem.
There was a test missing to catch this breakage, which this
commit adds as t4009-diff-rename-4.sh. The diff-raw tests used
in related t4005-diff-rename-2.sh (the same test without -z) and
t4007-rename-3.sh were stricter than necessarily, despite that
the comment for the tests said otherwise. This patch also
corrects them.
The documentation is updated to say that the status can
optionally be followed by a number called "score"; it does not
have to stay similarity index forever and there is no reason to
limit it only to C and R.

This is a complete rewrite of ls-tree to make it behave more
like what "/bin/ls -a" does in the current working directory.
Namely, the changes are:
- Unlike the old ls-tree behaviour that used paths arguments to
restrict output (not that it worked as intended---as pointed
out in the mailing list discussion, it was quite incoherent),
this rewrite uses paths arguments to specify what to show.
- Without arguments, it implicitly uses the root level as its
sole argument ("/bin/ls -a" behaves as if "." is given
without argument).
- Without -r (recursive) flag, it shows the named blob (either
file or symlink), or the named tree and its immediate
children.
- With -r flag, it shows the named path, and recursively
descends into it if it is a tree.
- With -d flag, it shows the named path and does not show its
children even if the path is a tree, nor descends into it
recursively.
This is still request-for-comments patch. There is no mailing
list consensus that this proposed new behaviour is a good one.
The patch to t/t3100-ls-tree-restrict.sh illustrates
user-visible behaviour changes. Namely:
* "git-ls-tree $tree path1 path0" lists path1 first and then
path0. It used to use paths as an output restrictor and
showed output in cache entry order (i.e. path0 first and then
path1) regardless of the order of paths arguments.
* "git-ls-tree $tree path2" lists path2 and its immediate
children but having explicit paths argument does not imply
recursive behaviour anymore, hence paths/baz is shown but not
paths/baz/b.

This attempts to optimize "diff-tree -[CM] --stdin", which
compares successible tree pairs. This optimization does not
make much sense for other commands in the diff-* brothers.
When reading from --stdin and using rename/copy detection, the
patch makes diff-tree to read the current index file first.
This is done to reuse the optimization used by diff-cache in the
non-cached case. Similarity estimator can avoid expanding a
blob if the index says what is in the work tree has an exact
copy of that blob already expanded.
Another optimization the patch makes is to check only file sizes
first to terminate similarity estimation early. In order for
this to work, it needs a way to tell the size of the blob
without expanding it. Since an obvious way of doing it, which
is to keep all the blobs previously used in the memory, is too
costly, it does so by keeping the filesize for each object it
has already seen in memory.

This changes the way how pathspec is used in the three diff-*
brothers. Earlier, they tried to grab as much information from
the original input and used pathspec to limit the output. This
version uses pathspec upfront to narrow the world diffcore
operates in, so "git-diff-* <arguments> some-directory" does not
look at things outside the specified subtree when finding
rename/copy or running pickaxe.
Since diff-tree already takes this view and does not feed
anything outside the specified directotires to begin with, this
patch does not have to touch that command.

Earier version of diffcore-rename used to keep unmodified
filepair in its output so that the last stage of the processing
that tells renames from copies can make all of rename/copy to
copies. However this had a bad interaction with other diffcore
filters that wanted to run after diffcore-rename, in that such
unmodified filepair must be retained for proper distinction
between renames and copies to happen.
This patch fixes the problem by changing the way diffcore-rename
records the information needed to distinguish "all are copies"
case and "the last one is a rename" case.

the "apply-patch" program Linus has been quietly working on
without much advertisement, it started to make sense to emit
usable information in the "diff --git" patch output format as
well. Earlier built-in diff driver punted and did not say
anything about a symbolic link changing into a file or vice
versa, but this version represents it as a pair of deletion

It also fixes a minor problem dealing with old archive created
