This allows git to be built even with linkers which are not smart enough
to join those symbols, and makes this correct C. Pointed out by several
people.
A deflate loop in sha1_file.c would have /* nothing */ as its
body, but the semicolon was missing, so the next command was run.
Fortunately the loop went through exactly once so it didn't trigger
an actual bug so far.

Some commands initialize sha1_file_directory by hand. There is no
need to do so; sha1_file.c knows how to handle it.
The next patch will remove the variable altogether.

It didn't properly mark all cache updates as being dirty, and
causes merge errors due to that. In particular, it didn't notice
when a file was force-removed.
Besides, it was ugly as hell. I've put in place a slightly cleaner
version, but I've not enabled the optimization because I don't
want to be burned again.
This updates the usage message string and Documentation/core-git.txt

Pass pointer to filecontents to write_header() and pass pointer
to filecontents, its size and some flags to write_exntended_header().
These parameters are not used, yet. They are added in preparation
to symlink support.
Introduce append_extended_header_prefix(), extended_header_len()
and append_extended_header(). These are helper functions that
make it easier to handle multiple entries in a pax extended
header. append_log() is no longer needed and can go away.
This allows you to trivially do fancy and readable output. Something like
git-rev-list HEAD | git-diff-tree -p -v --stdin kernel/ | less -S
gives a nice output of what has changed in the kernel/ subdirectory lately.
It turns out that parse_object() is loading and decompressing given
object to free it just before calling the specific object parsing
function which does mmap and decompress the same object again. This
patch introduces the ability to parse specific objects directly from a
memory buffer.
Without this patch, running git-fsck-cache on the kernel repositorytake:
real 0m13.006s
user 0m11.421s
sys 0m1.218s
With this patch applied:
real 0m8.060s
user 0m7.071s
sys 0m0.710s
The performance increase is significant, and this is kind of a
prerequisite for sane delta object support with fsck.

This only shows the tree headers when something actually changed. Also,
add a "silent" mode, which doesn't actually show the changes at all,
just the commit information.
This means that you can do
git-rev-list HEAD --max-count=10 | git-diff-tree --stdin update-cache.c
to see which (if any) of the last ten commits changed update-cache.c.
Use the "-m" flag to see merges too. Normally they are suppressed.
gitweb.cgi's default view is the log of the last day and git-rev-list
can stop crawling the whole repo if we have all our data to display in the
browser. Also the rss-feed query needs only the last 20 items. This
will speeds up these queries dramatically.

Fix update-cache to compare the blob of a symlink against the link-target
and not the file it points to. Also ignore all permissions applied to
links.

This moves the private "say()" function to pull.c, renames it to
"pull_say()", and introduces a global variable "get_verbosely" that
makes the pull backends report what they fetch. The -v option is
added to git-rpull and git-http-pull to match git-local-pull.
The documentation is updated to describe these pull commands.

The tree object parsing used to get the executable bit wrong,
and didn't know about symlinks. Also, fsck really wants the
full mode value so that it can verify the other bits for sanity,
so save it all in struct tree_entry.
Update git-apply-patch-script for symbolic links.
Make git-prune-script executable again.
Do not write out new index if nothing has changed.

This patch updates the git-apply-patch-script for the symbolic links
in the cache, recently added by Kay Sievers.
It currently is very anal about symbolic link changes. It refuses to
change between a regular file and a symbolic link, and only allows
symbolic link changes if the patch is based on the same original.

This patch updates the external diff interface engine for the change
to store the symbolic links in the cache, recently done by Kay
Sievers.
The main thing it does is when comparing with the work tree, it
prepares the counterpart to the blob being compared by doing a
readlink followed by sending that result to a temporary file to
be diffed.

While manually resolving a merge conflict, being able to run
diff-cache without --cache option between files in the work tree
and either of the ancestor trees is helpful to verify the hand
merged result. However, diff-cache refuses to handle unmerged
paths, even when run without --cache option.
This changes the behaviour so that the above use case will
report the differences between the compared tree and the magic
0{40} SHA1 (i.e. "look at the work tree"). When there is no
corresponding file in the work tree, or when the command is run
with "--cache" option, it continues to report "unmerged".

Separate out the merge resolve from the actual getting of the
data. Also, update the resolve phase to take advantage of the
fact that we don't need to do the commit->tree object lookup
by hand, since all the actors involved happily just act on a
commit object these days.
Allow to store and track symlink in the repository. A symlink is stored
the same way as a regular file, only with the appropriate mode bits set.
The symlink target is therefore stored in a blob object.
This will hopefully make our udev repository fully functional. :)
