Prune has to walk $GIT_DIR/objects/?? in order to find the
set of loose objects to prune. Other parts of the code
(e.g., count-objects) want to do the same. Let's factor it
out into a reusable for_each-style function.
Note that this is not quite a straight code movement. The
original code had strange behavior when it found a file of
the form "[0-9a-f]{2}/.{38}" that did _not_ contain all hex
digits. It executed a "break" from the loop, meaning that we
stopped pruning in that directory (but still pruned other
directories!). This was probably a bug; we do not want to
process the file as an object, but we should keep going
otherwise (and that is how the new code handles it).
We are also a little more careful with loose object
directories which fail to open. The original code silently
ignored any failures, but the new code will complain about
any problems besides ENOENT.

Fetching from a shallow-cloned repository used to be forbidden,
primarily because the codepaths involved were not carefully vetted
and we did not bother supporting such usage. This attempts to allow
object transfer out of a shallow-cloned repository in a controlled
way (i.e. the receiver become a shallow repository with truncated
history).
* nd/shallow-clone: (31 commits)

send-pack.c: mark a file-local function static
git-clone.txt: remove shallow clone limitations

send-pack: support pushing from a shallow clone via http
receive-pack: support pushing to a shallow clone via http

fetch: add --update-shallow to accept refs that update .git/shallow
upload-pack: make sure deepening preserves shallow roots
fetch: support fetching from a shallow repository
clone: support remote shallow repository
...
A few places where we relied on a fixed length buffer to hold
pathnames in these two programs have been converted to use strbuf.
* mh/path-max:
builtin/prune.c: use strbuf to avoid having to worry about PATH_MAX
prune-packed: use strbuf to avoid having to worry about PATH_MAX
While at it, rename prune_tmp_object(), which used to be a helper to
remove temporary files that were created to become loose object
files, to prune_tmp_file(), as the function is also used to remove
any random cruft whose name begins with tmp_ directly in .git/object
or .git/object/pack directories these days.

Leaving only the function definitions and declarations so that any
new topic in flight can still make use of the old functions, replace
existing uses of the prefixcmp() and suffixcmp() with new API
functions.
The change can be recreated by mechanically applying this:
$ git grep -l -e prefixcmp -e suffixcmp -- \*.c |
grep -v strbuf\\.c |
xargs perl -pi -e '
s|!prefixcmp\(|starts_with\(|g;
s|prefixcmp\(|!starts_with\(|g;
s|!suffixcmp\(|ends_with\(|g;
s|suffixcmp\(|!ends_with\(|g;

Commit b60daf0 (Make git-prune-packed a bit more chatty. - 2007-01-12)
changes the meaning of prune_packed_objects()'s argument, from "dry
run or not dry run" to a bitmap.
It however forgot to update prune_packed_objects() caller in
builtin/prune.c to use new DRY_RUN macro. It's fine (for a long time!)
but there is a risk that someday someone may change the value of
DRY_RUN to something else and builtin/prune.c suddenly breaks. Avoid
that possibility.
While at there, change "opts == VERBOSE" to "opts & VERBOSE" as there
is no obvious reason why we only be chatty when DRY_RUN is not set.

Earlier we added support for --expire=all (or --expire=now) that
considers all crufts, regardless of their age, as eligible for
garbage collection by turning command argument parsers that use
approxidate() to use parse_expiry_date(), but "git prune" used a
built-in parse-options facility OPT_DATE() and did not benefit from
the new function.

Not that we do not actively encourage having annotated tags outside
refs/tags/ hierarchy, but they were not advertised correctly to the
ls-remote and fetch with recent version of Git.
* jk/fully-peeled-packed-ref:
pack-refs: add fully-peeled trait
pack-refs: write peeled entry for non-tags
use parse_object_or_die instead of die("bad object")
avoid segfaults on parse_object failure
Some call-sites do:
o = parse_object(sha1);
if (!o)
die("bad object %s", some_name);
We can now handle that as a one-liner, and get more
consistent output.
In the third case of this patch, it looks like we are losing
information, as the existing message also outputs the sha1
hex; however, parse_object will already have written a more
specific complaint about the sha1, so there is no point in
repeating it here.

"git prune" reports removal of loose object files that are no longer
necessary only under the "-v" option, but unconditionally reports
removal of temporary files that are no longer needed.
The original thinking was that the presence of a leftover temporary
file should be an unusual occurrence that may indicate an earlier
failure of some sort, and the user may want to be reminded of it.
Removing an unnecessary loose object file, on the other hand, is
just part of the normal operation. That is why the former is always
printed out and the latter only when -v is used.
But neither report is particularly useful. Hide both of these
behind the "-v" option for consistency.

Both git-prune and git-repack (and thus, git-gc) try to rmdir while
holding a DIR* handle on the directory. This can leave dangling
empty directories in the .git/objects on platforms where directory
cannot be removed while they are open.
First call closedir() and then rmdir(); that is more logical ordering.

This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of
[torvalds@nehalem git]$ em buil<tab>
Display all 180 possibilities? (y or n)
[torvalds@nehalem git]$ em builtin-sh
builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c
builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o
[torvalds@nehalem git]$ em builtin-shor<tab>
builtin-shortlog.c builtin-shortlog.o
[torvalds@nehalem git]$ em builtin-shortlog.c
you get
[torvalds@nehalem git]$ em buil<tab> [type]
builtin/ builtin.h
[torvalds@nehalem git]$ em builtin [auto-completes to]
[torvalds@nehalem git]$ em builtin/sh<tab> [type]
shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o
[torvalds@nehalem git]$ em builtin/sho [auto-completes to]
[torvalds@nehalem git]$ em builtin/shor<tab> [type]
shortlog.c shortlog.o
[torvalds@nehalem git]$ em builtin/shortlog.c
which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.
NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead. I think bash has some cut-off
around 100 choices or something.
So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion. But you can
simulate that by using 'ls' instead, or something similar.
