d4a1cab541 Add new git-rm command with documentation
This adds a git-rm command which provides convenience similar to
git-add, (and a bit more since it takes care of the rm as well if
given -f).

Like git-add, git-rm expands the given path names through
git-ls-files. This means it only acts on files listed in the
index. And it does act recursively on directories by default, (no -r
needed as in the case of rm itself). When it recurses, it does not
remove empty directories that are left behind.

3fda8c4cc7 Introducing git-cvsserver -- a CVS emulator for git.
git-cvsserver is highly functional. However, not all methods are implemented,
and for those methods that are implemented, not all switches are implemented.
All the common read operations are implemented, and add/remove/commit are
supported.

Testing has been done using both the CLI CVS client, and the Eclipse CVS
plugin. Most functionality works fine with both of these clients.

Currently git-cvsserver only works over SSH connections, see the
Documentation for more details on how to configure your client. It
does not support pserver for anonymous access but it should not be
hard to implement. Anonymous access will need tighter input validation.

In our very informal tests, it seems to be significantly faster than a real
CVS server.

This utility depends on a version of git-cvsannotate that supports -S and on
DBD::SQLite.

aa064743fa git-push: Update documentation to describe the no-refspec behavior.
It turns out that the git-push documentation didn't describe what it
would do when not given a refspec, (not on the command line, nor in a
remotes file). This is fairly important for the user who is trying to
understand operations such as:

	git clone git://something/some/where
	# hack, hack, hack
	git push origin

I tracked the mystery behavior down to git-send-pack and lifted the
relevant portion of its documentation up to git-push, (namely that all
refs existing both locally and remotely are updated).

ca5381d43e pack-objects: finishing touches.
This introduces --no-reuse-delta option to disable reusing of
existing delta, which is a large part of the optimization
introduced by this series.  This may become necessary if
repeated repacking makes delta chain too long.  With this, the
output of the command becomes identical to that of the older
implementation.  But the performance suffers greatly.

It still allows reusing non-deltified representations; there is
no point uncompressing and recompressing the whole text.

It also adds a couple more statistics output, while squelching
it under -q flag, which the last round forgot to do.

There is one remaining issue when --no-reuse-delta option is not
used.  It can create delta chains that are deeper than specified.

    A<--B<--C<--D   E   F   G

Suppose we have a delta chain A to D (A is stored in full either
in a pack or as a loose object. B is depth1 delta relative to A,
C is depth2 delta relative to B...) with loose objects E, F, G.
And we are going to pack all of them.

B, C and D are left as delta against A, B and C respectively.
So A, E, F, and G are examined for deltification, and let's say
we decided to keep E expanded, and store the rest as deltas like
this:

    E<--F<--G<--A

Oops.  We ended up making D a bit too deep, didn't we?  B, C and
D form a chain on top of A!

This is because we did not know what the final depth of A would
be, when we checked objects and decided to keep the existing
delta.  Unfortunately, deferring the decision until just before
the deltification is not an option.  To be able to make B, C,
and D candidates for deltification with the rest, we need to
know the type and final unexpanded size of them, but the major
part of the optimization comes from the fact that we do not read
the delta data to do so -- getting the final size is quite an
expensive operation.

To prevent this from happening, we should keep A from being
deltified.  But how would we tell that, cheaply?

To do this most precisely, after check_object() runs, each
object that is used as the base object of some existing delta
needs to be marked with the maximum depth of the objects we
decided to keep deltified (in this case, D is depth 3 relative
to A, so if no other delta chain that is longer than 3 based on
A exists, mark A with 3).  Then when attempting to deltify A, we
would take that number into account to see if the final delta
chain that leads to D becomes too deep.

However, this is a bit cumbersome to compute, so we would cheat
and reduce the maximum depth for A arbitrarily to depth/4 in
this implementation.

7162dff3dd Add support for explicit type specifiers when calling git-repo-config
Currently, git-repo-config will just return the raw value of option
as specified in the config file; this makes things difficult for scripts
calling it, especially if the value is supposed to be boolean.

This patch makes it possible to ask git-repo-config to check if the option
is of the given type (int or bool) and write out the value in its
canonical form. If you do not pass --int or --bool, the behaviour stays
unchanged and the raw value is emitted.

This also incidentally fixes the segfault when option with no value is
encountered.

[jc: tweaked the option parsing a bit to make it easier to see
 that the patch does not change anything but the type stuff in
 the diff output.  Also changed to avoid "foo ? : bar" construct. ]

130fcca63f git-commit: revamp the git-commit semantics.
- "git commit" without _any_ parameter keeps the traditional
   behaviour.  It commits the current index.

   We commit the whole index even when this form is run from a
   subdirectory.

 - "git commit --include paths..." (or "git commit -i paths...")
   is equivalent to:

   	git update-index --remove paths...
        git commit

 - "git commit paths..." acquires a new semantics.  This is an
   incompatible change that needs user training, which I am
   still a bit reluctant to swallow, but enough people seem to
   have complained that it is confusing to them.  It

   1. refuses to run if $GIT_DIR/MERGE_HEAD exists, and reminds
      trained git users that the traditional semantics now needs
      -i flag.

   2. refuses to run if named paths... are different in HEAD and
      the index (ditto about reminding).  Added paths are OK.

   3. reads HEAD commit into a temporary index file.

   4. updates named paths... from the working tree in this
      temporary index.

   5. does the same updates of the paths... from the working
      tree to the real index.

   6. makes a commit using the temporary index that has the
      current HEAD as the parent, and updates the HEAD with this
      new commit.

 - "git commit --all" can run from a subdirectory, but it updates
   the index with all the modified files and does a whole tree
   commit.

 - In all cases, when the command decides not to create a new
   commit, the index is left as it was before the command is
   run.  This means that the two "git diff" in the following
   sequence:

       $ git diff
       $ git commit -a
       $ git diff

   would show the same diff if you abort the commit process by
   making the commit log message empty.

This commit also introduces much requested --author option.

8389b52b2a git-rerere: reuse recorded resolve.
In a workflow that employs relatively long lived topic branches,
the developer sometimes needs to resolve the same conflict over
and over again until the topic branches are done (either merged
to the "release" branch, or sent out and accepted upstream).

This commit introduces a new command, "git rerere", to help this
process by recording the conflicted automerge results and
corresponding hand-resolve results on the initial manual merge,
and later by noticing the same conflicted automerge and applying
the previously recorded hand resolution using three-way merge.

603968d22b daemon: extend user-relative path notation.
Earlier, we made --base-path to automatically forbid
user-relative paths, which was probably a mistake.  This
introduces --user-path (or --user-path=path) option to control
the use of user-relative paths independently.  The latter form
of the option can be used to restrict accesses to a part of each
user's home directory, similar to "public_html" some webservers
supports.

If we're invoked with --user-path=FOO option, then a URL of the
form git://~USER/PATH/... resolves to the path HOME/FOO/PATH/...,
where HOME is USER's home directory.

 original patch was done by Mark Wooding.]

b8bc67cef3 cvs-migration documentation update
Here's some changes to the cvs-migration.txt.  As usual, in my attempt
to make things clearer someone may have found I've made them less so, or
I may have just gotten something wrong; so any review is welcomed.

I can break up this sort of thing into smaller steps if preferred, the
monolothic patch is just a bit simpler for me for this sort of
thing.

I moved the material describing shared repository management from
core-tutorial.txt to cvs-migration.txt, where it seems more appropriate,
and combined two sections to eliminate some redundancy.

I also revised the earlier sections of cvs-migration.txt, mainly trying
to make it more concise.

I've left the last section of cvs-migration.txt (on CVS annotate
alternatives) alone for now.
