1fcdd62adf Merge branch 'master' into sp/fast-import
I'm bringing master in early so that the OBJ_OFS_DELTA implementation
is available as part of the topic.  This way git-fast-import can
learn about this new slightly smaller and faster packfile format,
and can generate them directly rather than needing to have them be
repacked with git-pack-objects.

Due to the API changes in master during the period of development
of git-fast-import, a few minor tweaks to fast-import.c are needed
to produce a working merge.  I've done them here as part of the
merge to ensure bisection always works.

6900679c2f Replacing the system call pread() with lseek()/xread()/lseek() sequence.
Using cygwin with cygwin.dll before 1.5.22 the system call pread() is buggy.
This patch introduces NO_PREAD. If NO_PREAD is set git uses a sequence of
lseek()/xread()/lseek() to emulate pread.

e194cd1e0e git-remote
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.

c869753ebb Force core.filemode to false on Cygwin.
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.

30f610b7b0 Create 'git gc' to perform common maintenance operations.
Junio asked for a 'git gc' utility which users can execute on a
regular basis to perform basic repository actions such as:

 * pack-refs --prune
 * reflog expire
 * repack -a -d
 * prune
 * rerere gc

So here is a command which does exactly that.  The parameters fed
to reflog's expire subcommand can be chosen by the user by setting
configuration options in .git/config (or ~/.gitconfig), as users may
want different expiration windows for each repository but shouldn't
be bothered to remember what they are all of the time.

4264dc15e1 git reflog expire
This prepares a place to collect reflog management subcommands,
and implements "expire" action.

	$ git reflog expire --dry-run \
		--expire=4.weeks \
		--expire-unreachable=1.week \
		refs/heads/master

The expiration uses two timestamps: --expire and --expire-unreachable.
Entries older than expire time (defaults to 90 days), and entries older
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.

The parameter handling is still rough, but I think the
core logic for expiration is already sound.

5cde71d64a git-add --interactive
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.

1510fea781 Avoid accessing a slow working copy during diffcore operations.
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.

857b933e04 xdiff: add xdl_merge()
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.

ed09aef06f support fetching into a shallow repository
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.

acca687fa9 git-pickaxe: retire pickaxe
Just make it take over blame's place.  Documentation and command
have all stopped mentioning "git-pickaxe".  The built-in synonym
is left in the command table, so you can still say "git pickaxe",
but it probably is a good idea to retire it as well.

af8ffbed0f Remove SIMPLE_PROGRAMS and make git-daemon a normal program.
Some platforms (Solaris in particular) appear to require -lz as
part of the link line for git-daemon, due to it linking against
sha1_file.o and that module requiring inflate/deflate support.

So its time to retire SIMPLE_PROGRAMS and move its last remaining
member into the standard PROGRAMS list, allowing it to link against
all libraries used by the rest of Git.

da093d3750 improve fetch-pack's handling of kept packs
Since functions in fetch-clone.c were only used from fetch-pack.c,
its content has been merged with fetch-pack.c.  This allows for better
coupling of features with much simpler implementations.

One new thing is that the (abscence of) --thin also enforce it on
index-pack now, such that index-pack will abort if a thin pack was
_not_ asked for.

The -k or --keep, when provided twice, now causes the fetched pack
to be left as a kept pack just like receive-pack currently does.
Eventually this will be used to close a race against concurrent
repacking.

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 patch removes Git.xs from the repository for the time being. This
should hopefully enable Git.pm to finally make its way to master.

Git.xs is not going away forever. When the Git libification makes some
progress, it will hopefully return (but most likely as an optional
component, due to the portability woes) since the performance boosts are
really important for applications like Gitweb or Cogito. It needs to go
away now since it is not really reliable in case you use it for several
repositories in the scope of a single process, and that is not possible
to fix without some either very ugly or very intrusive core changes.

Rest in peace. (While you can.)

 * pattern strings and extended grep expressions are added to

 * 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.

This also adds an internal option "status_only" to grep_opt,
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.

e1e22e37f4 Start handling references internally as a sorted in-memory list
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 ]

358ddb62cf Add "git show-ref" builtin command
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.

39345a216f Add git-upload-archive
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.

4df096a5ca Add git-archive
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).

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.

7cf67205ca Trace into open fd and refactor tracing code.
Now if GIT_TRACE is set to an integer value greater than 1
and lower than 10, we interpret this as an open fd value
and we trace into it. Note that this behavior is not
compatible with the previous one.

We also trace whole messages using one write(2) call to
make sure messages from processes do net get mixed up in
the middle.

It's now possible to run the tests like this:

	GIT_TRACE=9 make test 9>/var/tmp/trace.log

e4fbbfe9ec Add git-zip-tree
In the Windows world ZIP files are better supported than tar files.
Windows even includes built-in support for ZIP files nowadays.

git-zip-tree is similar to git-tar-tree; it creates ZIP files out of
git trees.  It stores the commit ID (if available) in a ZIP file comment
which can be extracted by unzip.

There's still quite some room for improvement: this initial version
supports no symlinks, calls write() way too often (three times per file)
and there is no unit test.
