All usage strings are now declared as static const char [].
This is carried over from my old git-pb branch.

Here is a patch that fixes several gcc4 warnings about different signedness,
all between char and unsigned char. I tried to keep the patch minimal
so resertod to casts in three places.

write_trailer() writes the last 10k (a full block) of the tar archive.
write_if_needed() writes out a block *if* it is full and then sets
the offset to 0. In nine out of ten cases the messed up write_trailer()
function didn't manage to fill the block thus not writing anything at
all, truncating the archive. I was "lucky" to hit the other case and so
my testing ran OK.

Fix various things that sparse complains about:
- use NULL instead of 0
- make sure we declare everything properly, or mark it static
- use proper function declarations ("fn(void)" instead of "fn()")
Sparse is always right.

Fixes all in-code names that leaved during "big name change".

- Raw hashes should be unsigned char.
- String functions want signed char.
- Hash and compress functions want unsigned char.

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.

Add symlink support to git-tar-tree.
|
|
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.
|
|
Add TYPEFLAG_ constants.
|
|
Add get_record() which returns a pointer to the next record in the block.
|
|
This allows the programs to use various simplified versions of
the SHA1 names, eg just say "HEAD" for the SHA1 pointed to by
the .git/HEAD file etc.
For example, this commit has been done with
git-commit-tree $(git-write-tree) -p HEAD
instead of the traditional "$(cat .git/HEAD)" syntax.

Write commit ID to global extended pax header at the beginning of the tar
file, if possible. get-tar-commit-id.c is an example program to get the
ID back out of such a tar archive.

This patch replaces the usage of read_tree_with_tree_or_commit_sha1()
with read_object_with_reference() in tar-tree. As a result the code
that tries to figure out the commit time doesn't need to open the commit
object 'by hand' any more.

This is an improved version of tar-tree, a streaming archive creator for
GIT. The major added feature is blocking; all write(2) calls now have a
size of 10240, just as GNU tar (and tape drives) likes them. The
buffering overhead does not seem to degrade performance because most
files in the repositories I tested this with are smaller than 10KB, so
we need fewer system calls.
File names are still restricted to 500 bytes and the archive format
currently only allows for files up to 8GB. Both restrictions can be
lifted if need be with more pax extended headers.
The archive format used is the pax interchange format, i.e. POSIX tar
format. It can be read by (and created with) GNU tar. If I read the
specs correctly tar-tree should now be standards compliant (modulo
bugs).
Because it streams the archive (think ls-tree merged with cat-file),
tar-tree doesn't need to create any temporary files. That makes it
quite fast.
It accepts tree IDs and commit IDs as first parameter. In the latter
case tar-tree tries to get the commit date out of the committer line.
Else all files in the archive are time-stamped with the current time.
An optional second parameter is used as a path prefix for all files in
the archive. Example:
$ tar-tree a2755a80f40e5794ddc20e00f781af9d6320fafb \
