f5cabd13d8 Encode a few extra flags per index entry.
This will allow us to have the same name in different "states" in the
index at the same time. Which in turn seems to be a very simple way to
merge.

ca2a079865 [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.

ccc4feb579 Convert the index file reading/writing to use network byte order.
This allows using a git tree over NFS with different byte order, and
makes it possible to just copy a fully populated repository and have
the end result immediately usable (needing just a refresh to update
the stat information).

27de946d0e [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 :)

commit-tree now eats RFC2822 dates as AUTHOR_DATE because that's
what you're going to want to feed it.

Yes, glibc sucks and strptime is a pile of crap. We have to parse it
ourselves.

aa1c48df81 [PATCH] ls-tree enhancements
This adds '-r' (recursive) option and '-z' (NUL terminated)
option to ls-tree.  I need it so that the merge-trees (formerly
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.

It is relative to bb95843a5a0f397270819462812735ee29796fb4

458754a9fe Use common "revision.h" header for both fsck and rev-tree.
It's really a very generic thing: the notion of one sha1 revision
referring to another one. "fsck" uses it for all nodes, and "rev-tree"
only tracks commit-node relationships, but the code was already
the same - now we just make that explicit by moving it to a common
header file.

"arbitrary" is a bit wrong, since it is limited by the argument
size limit (128kB or so), but let's see if anybody ever cares.
Arguably you should prune your tree before you have a few thousand
dangling heads in your archive.

We can fix it by passing in a file listing if we ever care.

727ff27787 [PATCH] rev-tree support for "in X but not in Y".
To do the automated commit-mailing I need to be able to answer the
question "which commits are here today but weren't yesterday"...  i.e. 
given two commit-ids $HEAD and $YESTERDAY I want to be able to do:

	rev-tree $HEAD ^$YESTERDAY

to list those commits which are in the tree now but weren't
ancestors of yesterday's head.

Yes, I could probably do this with 
	rev-tree $HEAD $YESTERDAY | egrep -v ^[a-z0-9]*:3
but I prefer not to.

c0fb976aa7 [PATCH] show-diff show deleted files as diff as well.
The ideas is that using the show-diff to generate the
patch including deleted and new file (in the next patch).
So we don't have to do the temp new file diff dance on the
script.

The cache index now contain enough information to generate
the whole patch. So the GIT SCM don't need separate command
for check out file to edit or delete. Just do the edit and
remove and GIT will generate the correct patch.

It still require tell GIT to add new files.

I looked a bit at my old BK tools for the same thing, but they were

data from one process to another (which was clever but very hard

771364af0e Make the rev-tree output more regular. This is the last
change. Promise.

It now always outputs all the revisions as <sha1>:<reachability>, where the
reachability is the bitmask of how that revision was reachable from the
commits in the argument list.

Trivially, if there is only one commit, the reachability will always be
(1 << 0) == 1 for all reachable revisions, and there won't be any edges
(so the "--edges" flag only makes sense with multiple commit keys).
