On Solaris machines gnu install called ginstall
<JC> Editorial notes. I've also changed it to use $(COPTS), $(prefix),
and $(bin) because I always get confused without compiling it with -O1
when I single step in gdb. The default is left as Linus shipped.

<JC> Editorial Note. We may want to include standard headers in one
of those headers everybody includes, e.g. cache.h, to reduce clutters,
but this commit is as Thomas posted to the GIT list.

Thomas Glanzmann says that shell he uses on Solaris cannot grok
$(command) but the script does not use nested $(command) and
works happily just by using backticks instead.

Kay Sievers noticed that you can have both path and path/file in
the cache and write-tree happily creates a tree object from such
a state. Since a merge can result in such situation and the
user should be able to see the situation by looking at the
cache, rather than forbidding add_cache_entry() to create such
conflicts, fix it by making write-tree refuse to write such an
nonsensical tree. Here is a test case.
-- test case --
$ ls -a
./ ../
$ git-init-db
defaulting to local storage area
$ date >path
$ git-update-cache --add path
$ rm path
$ mkdir path

An unmerged path is given as the sole parameter to the script, so it

SHA1_FILE_DIRECTORIES environment variable is a colon separated paths
used when looking for SHA1 files not found in the usual place for
reading. Creating a new SHA1 file does not use this alternate object
database location mechanism. This is useful to archive older, rarely
used objects into separate directories.

Some commands initialize sha1_file_directory by hand. There is no

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.

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.

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. :)
