It was cumbersome to feed hash-object the file '-t' (you could

8d69195124 Fix 5501 test
Not everybody can rely on /bin/sh to be sane, and we support
SHELL_PATH for that.  Use it.

mktemp(1) is not used anywhere else in the core git.  Do not
introduce dependency on it.

Not everybody's "which" gives a sane return value.  For example,
on Solaris 'which XXX' says "no XXX in /usr/bin /bin ..." and
exits with zero status.  The lesson here is to never use 'which'
in your scripts.

4050c0df8e Clean up compatibility definitions.
This attempts to clean up the way various compatibility
functions are defined and used.

 - A new header file, git-compat-util.h, is introduced.  This
   looks at various NO_XXX and does necessary function name
   replacements, equivalent of -Dstrcasestr=gitstrcasestr in the
   Makefile.

 - Those function name replacements are removed from the Makefile.

 - Common features such as usage(), die(), xmalloc() are moved
   from cache.h to git-compat-util.h; cache.h includes
   git-compat-util.h itself.

Again, dumb transport clients are too dumb to make use of the
top objects information to make a choice among multiple packs,

d79374c7b5 [PATCH] daemon.c and path.enter_repo(): revamp path validation.
The whitelist of git-daemon is checked against return value from
enter_repo(), and enter_repo() used to return the value obtained
from getcwd() to avoid directory aliasing issues as discussed
earier (mid October 2005).

Unfortunately, it did not go well as we hoped.

For example, /pub on a kernel.org public machine is a symlink to
its real mountpoint, and it is understandable that the
administrator does not want to adjust the whitelist every time
/pub needs to point at a different partition for storage
allcation or whatever reasons.  Being able to keep using
/pub/scm as the whitelist is a desirable property.

So this version of enter_repo() reports what it used to chdir()
and validate, but does not use getcwd() to canonicalize the
directory name.  When it sees a user relative path ~user/path,
it internally resolves it to try chdir() there, but it still
reports ~user/path (possibly after appending .git if allowed to
do so, in which case it would report ~user/path.git).

What this means is that if a whitelist wants to allow a user
relative path, it needs to say "~" (for all users) or list user
home directories like "~alice" "~bob".  And no, you cannot say
/home if the advertised way to access user home directories are
~alice,~bob, etc.  The whole point of this is to avoid
unnecessary aliasing issues.

Anyway, because of this, daemon needs to do a bit more work to
guard itself.  Namely, it needs to make sure that the accessor
does not try to exploit its leading path match rule by inserting
/../ in the middle or hanging /.. at the end.  I resurrected the
belts and suspender paranoia code HPA did for this purpose.

This check cannot be done in the enter_repo() unconditionally,
because there are valid callers of enter_repo() that want to
honor /../; authorized users coming over ssh to run send-pack
and fetch-pack should be allowed to do so.

0f8f45cb4a git-ls-tree: add "-t" option to always show the tree entries
The old (new) behaviour was that it only shows trees if the object is
specified exactly, and recursive is not set. That makes sense, because
there is obviously nothing else it can show for that case.

However, with the new "-t" option, it will show the tree even with "-r",
as it traverses down into it.

NOTE! This also means that it will show all trees leading up to that tree.

For example, if you do a

	git-ls-tree -t HEAD -- drivers/char/this/file/does/not/exist

it will show the trees that lead up to the files that do not exist:

	[torvalds@g5 linux]$ git-ls-tree -t HEAD -- drivers/char/this/file/does/not/exist
	040000 tree 9cb687b77dcd64bf82e9a73214db467c964c1266    drivers
	040000 tree 298e2fadf0ff3867d1ef49936fd2c7bf6ce1eb66    drivers/char
	[torvalds@g5 linux]$

and note how this is true even though I didn't specify "-r": the fact that
I supplied a pathspec automatically implies "enough recursion" for that
particular pathspec.

I think the code is cleaner and easier to understand too: the patch looks
bigger, but it's really just splitting up the "should we recurse into this
tree" into a function of its own.
