 - Although it was advertised that the initial break criteria

   for this change, the default break score is also changed to

 - The code would have crashed with division by zero when trying

to apply different criteria; namely, regardless of the amount of
new material in the result, the determination of "rewrite"
should be done by looking at the amount of original material
still left in the result.  If you still have the original 97
lines from a 100-line document, it does not matter if you add
your own 13 lines to make a 110-line document, or if you add 903
lines to make a 1000-line document.  It is not a rewrite but an
in-place edit.  On the other hand, if you did lose 97 lines from
the original, it does not matter if you added 27 lines to make a
30-line document or if you added 997 lines to make a 1000-line
document.  You did a complete rewrite in either case.

This patch introduces a post-processing phase that runs after
diffcore-rename matches up broken pairs diffcore-break creates.
The purpose of this post-processing is to pick up these broken
pieces and merge them back into in-place modifications.  For
this, the score parameter -B option takes is changed into a pair
of numbers, and it takes "-B99/80" format when fully spelled
out.  The first number is the minimum amount of "edit" (same
definition as what diffcore-rename uses, which is "sum of
deletion and insertion") that a modification needs to have to be
broken, and the second number is the minimum amount of "delete"
a surviving broken pair must have to avoid being merged back
together.  It can be abbreviated to "-B" to use default for
both, "-B9" or "-B9/" to use 90% for "edit" but default (80%)
for merge avoidance, or "-B/75" to use default (99%) "edit" and

asked from the remote side when it is.  Since this partial

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

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

rewrite is broken into a deletion followed by a creation.  This

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.

[PATCH] Rewrite ls-tree to behave more like "/bin/ls -a"

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.

[PATCH] Optimize diff-tree -[CM] --stdin

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
