74400e7175 Add git-write-blob.
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.

0980d9b3a5 Change the prefix for builtin diff generation.
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 ;)

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.

7fa76eeb75 [PATCH] typo fixes to git-apply-patch-script
When git-apply-patch-script creates a new file without
executable mode set, a typo caused it not to report that

git-update-cache twice for newly created or deleted paths.  This

ee4f439fea [PATCH] Do not call fetch() when we have it.
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.

I will be sending a trivial git-local-pull which depends on
this in the next message.

90535218dd [PATCH] Make git-update-cache --refresh fail if update/merge needed.
Scripts may find it useful if they do not have to parse the

Earlier both Linus and myself thought this would be necessary to
make git-prune-script safer but it turns out that the issue was
somewhere else and not related to what this patch addresses.

Linus Torvalds
11e7d5c594 Make "cat-file" use "read_object_with_reference()"
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.

ca4c7db9ef Remove the ugly jit-style parent syntax.
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.

35ad33823e Add "look up parent" logic for the simple names.
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.

3c249c9506 Add "get_sha1()" helper function.
This allows the programs to use various simplified versions of

For example, this commit has been done with

	git-commit-tree $(git-write-tree) -p HEAD

instead of the traditional "$(cat .git/HEAD)" syntax.

e2a669bb2e [PATCH] Allow removing files in a subdirectory.
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
fix.

21a08dcbe7 [PATCH] Really fix git-merge-one-file-script this time.
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.

5d2f8b2753 [PATCH] Add git-apply-patch-script.
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>

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 also regularizes the make. The source files themselves don't get
the "git-" prefix, because that's just inconvenient. So instead we just
make the rule that "git-xxxx" depends on "xxxx.c", and do that for
all the core programs (ie the old "git-mktag.c" got renamed to just
"mktag.c" to match everything else).

And "show-diff" got renamed to "git-diff-files" while at it, since
that's what it really should be to match the other git-diff-xxx cases.
