Now, show_date() can print three different kinds of dates: normal,
relative and short (%Y-%m-%s) dates.
To achieve this, the "int relative" was changed to "enum date_mode
mode", which has three states: DATE_NORMAL, DATE_RELATIVE and
DATE_SHORT.
Since existing users of show_date() only call it with relative_date
being either 0 or 1, and DATE_NORMAL and DATE_RELATIVE having these
values, no behaviour is changed.

So when we do
git show v1.4.4..v1.5.0
that's an illogical thing to do, since "git show" is defined to be a
non-revision-walking action, which means the range operator be pointless
and wrong. The fact that we happily accept it (and then _only_ show
v1.5.0, which is the positive end of the range) is quite arguably not very
logical.
We should complain, and say that you can only do "no_walk" with positive
refs. Negative object refs really don't make any sense unless you walk
the obejct list (or you're "git diff" and know about ranges explicitly).

The config option gitcvs.allbinary may be set to force all entries to
get the -kb flag.
In the future the gitattributes system will probably be a more
appropriate way of doing this, but that will easily slot in as the
entries lines sent to the CVS client now have their kopts set via the
function kopts_from_path().
In the interim it might be better to not just have a all-or-nothing
approach, but rather detect based on file extension (or file contents?).
That would slot in easily here as well. However, I personally prefer
everything to be binary-safe, so I just switch the switch.

The commithash for updating the ref is obtained from a call to
git-commit-tree. However, it was returned (and stored) with the
trailing newline. This meant that the later call to git-update-ref that
was trying to update to $commithash was including the newline in the
parameter - obviously that hash would never exist, and so git-update-ref
would always fail.
The solution is to chomp() the commithash as soon as it is returned by
git-commit-tree.

This makes "ci" codepath lockless by following the usual
"remember the tip, do your thing, then compare and swap at the
end" update pattern using update-ref. Incidentally, by updating
the code that reads where the tip of the head is to use
show-ref, it makes it safe to use in a repository whose refs are
pack-pruned.
I noticed that other parts of the program are not yet pack-refs
safe, but tried to keep the changes to the minimum.

We currently have two parallel notation for dealing with object types
in the code: a string and a numerical value. One of them is obviously
redundent, and the most used one requires more stack space and a bunch
of strcmp() all over the place.
This is an initial step for the removal of the version using a char array
found in object reading code paths. The patch is unfortunately large but
there is no sane way to split it in smaller parts without breaking the
system.

First there are too many offsets there and it is getting confusing.
So 'offset' is now 'curpos' to distinguish from other offsets like
'obj_offset'.
Then structures like x = foo(x, &y) are now done as y = foo(&x).
It looks more natural that the result y be returned directly and
x be passed as reference to be updated in place. This has the effect
of reducing some line length and removing a few, needing a bit less
stack space, and it even reduces the compiled code size.

Let's have hdr be a simple char pointer/array when possible, and let's
reduce its storage to 32 bytes. Especially for sha1_loose_object_info()
where 128 bytes is way excessive and wastes extra CPU cycles inflating.
The object type is already restricted to 10 bytes in parse_sha1_header()
and the size, even if it is 64 bits, will fit in 20 decimal numbers. So
32 bytes is plenty.

git-apply: do not fix whitespaces on context lines.
diff --cc: integer overflow given a 2GB-or-larger file
mailinfo: do not get confused with logical lines that are too long.
Internal function apply_line() is called to copy both context lines
and added lines to the output buffer, while possibly fixing the
whitespace breakages depending on --whitespace=strip settings.
However, it did its fix-up on both context lines and added lines.
This resulted in two symptoms:
(1) The number of lines reported to have been fixed up included
these context lines.
(2) However, the lines actually shown were limited to the added
lines that had whitespace breakages.

Few of us use git to compare or even version-control 2GB files,
but when we do, we'll want it to work.
Reading a recent patch, I noticed two lines like this:
int len = st.st_size;
Instead of "int", that should be "size_t". Otherwise, in the
non-symlink case, with 64-bit size_t, if the file's size is 2GB,
the following xmalloc will fail:
result = xmalloc(len + 1);
trying to allocate 2^64 - 2^31 + 1 bytes (assuming sign-extension
in the int-to-size_t promotion). And even if it didn't fail, the
subsequent "result[len] = 0;" would be equivalent to an unpleasant
"result[-2147483648] = 0;"
The other nearby "int"-declared size variable, sz, should also be of
type size_t, for the same reason. If sz ever wraps around and becomes
negative, xread will corrupt memory _before_ the "result" buffer.

It basically considers all the continuation lines to be lines of their
own, and if the total line is bigger than what we can fit in it, we just
truncate the result rather than stop in the middle and then get confused
when we try to parse the "next" line (which is just the remainder of the
first line).

Mark Levedahl noticed that git-gui will let you create an empty
normal (non-merge) commit if the file state in the index is out
of whack. The case Mark was looking at was with the new autoCRLF
feature in git enabled and is actually somewhat difficult to create.
I found a different way to create an empty commit: turn on the
Trust File Modifications flag, touch a file, rescan, then move
the file into the "Changes To Be Committed" list without looking
at the file's diff. This makes git-gui think there are files
staged for commit, yet the update-index call did nothing other
than refresh the stat information for the affected file. In
this case git-gui allowed the user to make a commit that did
not actually change anything in the repository.
Creating empty commits is usually a pointless operation; rarely
does it record useful information. More often than not an empty
commit is actually an indication that the user did not properly
update their index prior to commit. We should help the user out
by detecting this possible mistake and guiding them through it,
rather than blindly recording it.
After we get the new tree name back from write-tree we compare
it to the parent commit's tree; if they are the same string and
this is a normal (non-merge, non-amend) commit then something
fishy is going on. The user is making an empty commit, but they
most likely don't want to do that. We now pop an informational
dialog and start a rescan, aborting the commit.

cehteh on #git noticed that there was no way to perform a reset --hard
from within git-gui. When I pointed out this was Merge->Abort Merge
cehteh said this is not very understandable, and that most users would
never guess to try that option unless they were actually in a merge.
So Branch->Reset is now also a way to cause a reset --hard from within
the UI. Right now the confirmation dialog is the same as the one used
in Merge->Abort Merge.

diff sets the exit status to 0 when no changes were found, to 1
when changes were found, and 2 means error.
We imitate this to be able to use "git diff" in the test scripts.
(Actually, keeping in line with the rest of git, -1 is returned
on error, which corresponds to an exit status 255).
To find out if the diff is not empty, a member called
"found_changes" was introduced in struct diff_options, which is
set in builtin_diff() and fn_out_consume().
