We check the ordering of the entries, and we verify that none
of the entries has a slash in it (this allows us to remove the
hacky "has_full_path" member from the tree structure, since we
now just test it by walking the tree entries instead).

This improves the cold-cache behaviour on most filesystems,
since it makes the fsck access patterns more regular on
the disk, rather than seeking back and forth.
Note the "most". Not all filesystems have any relationship
between inode number and location on disk.
With this change, git-merge-one-file-script ceases to smudge
files in the work tree when recording the trivial merge results
(conflicting auto-merge failure case does not touch the work
tree file as before).

This new flag tells git-update-cache to remove the named path even
when the work tree still happens to have the file. It is used to
update git-merge-one-file-script not to smudge the work tree.

A new command, git-write-blob, is introduced. This registers
the contents of any file on the filesystem as a blob in the
object database and reports its SHA1 to the standard output.
To implement it, the patch promotes index_fd() from a static
function in update-cache.c to extern and moves it to a library
source, sha1_file.c.
This command is used to update git-merge-one-file-script so that
it does not smudge the work tree.

It's silly, and it shouldn't matter, but every time I look at
the diffs, I ended up just worrying why "l/" and "k/" as the
prefixes.
Junio says it's a tribute to linux-kernel, but graciously also
said I can change it to something else. So make it "a/" and "b/"
until somebody else complains ;)
Now that git does pretty reliable date parsing, we might as well get
the date from the email itself. Of course, it's still questionable
whether the date on the email is all that relevant, but it's certainly
no worse than taking the commit date.
This is to be applied on top of the previous patch to add
git-local-pull command. In addition to the '-l' (attempt
hardlink before anything else) and the '-s' (then attempt
symlink) flags, it adds '-n' (do not fall back to file copy)
flag. Also it updates the comments.

When git-apply-patch-script creates a new file without

Currently pull() calls fetch() without checking whether we have
the wanted object but all of the existing fetch()
implementations perform this check and return success
themselves. This patch moves the check to the caller.

Scripts may find it useful if they do not have to parse the
output from the command but just can rely on its exit status.

This means that you can take a tag object, and do
git-cat-file commit tagname
and it will cat the commit that the tag points to. Or you can
cat the tree that a commit (or tag) points to.
It still gives the old behaviour if you just give it the
original type, ie if you want to see the tag object itself,
you'd do
git-cat-file -t tagname
and you'd get the expected tag output.
If somebody wants it later, we can re-do it, but for now we consider
it an experiment that wasn't worth it. Git will still honor symbolic
names, it just won't look up parents for you.
Of course, you can always do it by hand if you want to.
It uses the jit syntax, at least for now. 0-xxxx is the first parent of xxxx,
while 1-xxxx is the second, and so on. You can use just "-xxxx" for the first
parent, but a lot of commands will think that the initial '-' implies a
command line flag.
This allows the programs to use various simplified versions of
the SHA1 names, eg just say "HEAD" for the SHA1 pointed to by
the .git/HEAD file etc.
For example, this commit has been done with
git-commit-tree $(git-write-tree) -p HEAD
instead of the traditional "$(cat .git/HEAD)" syntax.
And be a bitmore careful about matching: if we don't recognize a word
or a number, we skip the whole thing, rather than trying the next character
in that word/number.
Finally: since ctime() adds the final '\n', don't add another one in test-date.
I found this during a conflict merge testing. The original did
not have either DF (a file) or DF/DF (a file DF/DF under a
directory DF). One side created DF, the other created DF/DF. I
first resolved DF as a new file by taking what the first side
did. After that, the entry DF/DF cannot be resolved by running
git-update-cache --remove although it does not exist on the
filesystem.
$ /bin/ls -F
AN DF MN NM NN SS Z/
$ git-ls-files --stage | grep DF
100644 71420ab81e254145d26d6fc0cddee64c1acd4787 0 DF
100644 68a6d8b91da11045cf4aa3a5ab9f2a781c701249 2 DF/DF
$ git-update-cache --remove DF/DF
fatal: Unable to add DF/DF to database
It turns out that the errno from open() in this case was not
ENOENT but ENOTDIR, which the code did not check. Here is a

The merge-cache program was updated to pass executable bits when
calling git-merge-one-file-script, but the called script
supplied as an example were not using them carefully.
This patch fixes the following problems in the script:
* When a new file is created in a directory, which is a file in
the work tree, it tried to create leading directory but did
not check for failure from the "mkdir -p" command.
* The script did not check the exit status from the
git-update-cache command at all.
* The parameter "$4" to the script is a file name that can
contain almost any characters, so it must be quoted with
double quotes and also needs to be preceded with -- to mark
it as a non-option when passed to certain commands.
* The chmod command was used with parameter "$6" or "$7" to set
the mode bits. This contradicts with the strategy taken by
checkout-cache, where we honor user's umask and force only
the executable bits. With this patch, it creates a new file
by redirecting into it (thus honoring user's default umask),
and then uses "chmod +x" if we want the resulting file
executable. Without this fix, the merge result becomes 0644
or 0755 for users whose umask is 002 for whom it should
become 0664 or 0775.
* When "$1 -> $2 -> $3" case was not handled, the script did
not say which path it was working on, which was not so useful
when used with the -a option of git-merge-cache.

I said:
- Stop attempting to be compatible with cg-patch, and drop
(mode:XXXXXX) bits from the diff.
- Do keep the /dev/null change for created and deleted case.
- No "Index:" line, no "Mode change:" line, anywhere in the
output. Anything that wants the mode bits and sha1 hash can
do things from GIT_EXTERNAL_DIFF mechanism. Maybe document
suggested usage better.
This adds an example script git-apply-patch-script, that can be
used as the GIT_EXTERNAL_DIFF to apply changes between two trees
directly on the current work tree, like this:
GIT_EXTERNAL_DIFF=git-apply-patch-script git-diff-tree -p <tree> <tree>

This still doesn't actually really _use_ it properly, nor make any
distinction between different DST rules, but at least we could (if
we wanted to) fake it a bit better.
Right now the code actually still says "it's always summer". I'm
from Finland, I don't like winter.
Show the types of objects involved in broken links, and don't bother
warning about unreachable tag files (if somebody cares about tags,
they'll use the --tags flag to see them).
...since everything out there is either strange (libc mktime has issues
with timezones) or introduces unnecessary dependencies for people (libcurl).
This goes back to the old date parsing, but moves it out into a file of
its own, and does the "struct tm" to "seconds since epoch" handling by
hand.
I grepped through the tz-database and it seems there's one "country"
left that has non-60-minute DST: Lord Howe Island. All others dropped
that before 1970.
This switches git-commit-tree to using curl_getdate() for the
AUTHOR_DATE, and thus fixes the problem with "mktime()" parsing dates in
the local timezone. It also ends up being more permissive about the
format of the date.
