[PATCH] Add "-q" option to show-diff.c
This adds the '-q' option for show-diff.c to squelch complaints for
missing files.
It is handy if you want to run it in the merge temporary directory after
running merge-trees with its minimum checkout mode, which is the
default, because you would not find any files other than the ones that
needs human validation after the merge there.
It also fixes the argument parsing bug Paul Mackerras noticed in
<16991.42305.118284.139777@cargo.ozlabs.ibm.com> but slightly
differently.

[PATCH] Simplify date handling and make it more reliable
This make all dates be stores as seconds since UTC epoch, with the
author's or committer's timezone as auxiliary data so that dates can be
pretty-printed in the original timezone later if anyone cares. I left
the date parsing in rev-tree.c for backward compatibility but it can be
dropped when we change to base64 :)

what you're going to want to feed it.

[PATCH] ls-tree enhancements
This adds '-r' (recursive) option and '-z' (NUL terminated)

known as git-merge.perl) script does not need to create any
temporary dircache while merging. It used to use show-files on
a temporary dircache to get the list of files in the ancestor
tree, and also used the dircache to store the result of its
automerge. I probably still need it for the latter reason, but
with this patch not for the former reason anymore.

Add "-lz" to link line to get in zlib.
Not all Linux distributions seem to need it (notably not YDL on ppc64), but
enough ones obviously do.

Add new fsck-cache to Makefile.
This is what happens when there are no nice tools to tell you to do things
properly.

Add first cut at "fsck-cache" that validates the SHA1 object store.
It doesn't complain about mine. But it also doesn't yet check for
inter-object reachability etc.
Linus Torvalds [Fri, 8 Apr 2005 22:01:15 +0000 (15:01 -0700)]
Add "check_sha1_signature()" helper function
And fix up header declarations.

Factor out "read_sha1_file" into mapping/inflating/unmapping.
This allows us to also actually check the sha1 hash using these
routines. Needed for the "fsck" thing.

Use "-Wall -O2" for the compiler to get more warnings.
And fix up the warnings that it pointed out. Let's keep the tree
clean from early on.
Not that the code is very beautiful anyway ;)

Make "cat-file" output the file contents to stdout.
New syntax: "cat-file -t <sha1>" shows the tag, while "cat-file <tag> <sha1>"
outputs the file contents after checking that the supplied tag matches.
Linus Torvalds [Fri, 8 Apr 2005 04:03:28 +0000 (21:03 -0700)]
Make read-tree actually unpack the whole tree.
I needed this to make a "sparse" archive conversion from my old
BitKeeper tree data. The scripts to do the conversion are just
incredibly ugly, but they seem to validate the notion that you
can actually use this silly 'git' thing to save your history in.

Add copyright notices.
The tool interface sucks (especially "committing" information, which is just
me doing everything by hand from the command line), but I think this is in
theory actually a viable way of describing the world. So copyright it.
