It's stupid. We'd want to rename directories too, but this doesn't do
that yet - easy enough to do per se, we just need to carefully list all
the pathnames that got moved (and remember to ignore the files that
weren't tracked but are in the subdirectory that got moved).
Doing the directory case will require a bit more scripting.. Something like
oldfiles=($(git-ls-files | grep '^$src'))
newfiles=($(git-ls-files | sed ':^$src: s:^$src:$dst:'))
mv $src $dst && git-update-cache --add --remove -- "${oldfiles[@]}" "${newfiles[@]}"
might do it, except it needs to be done right, and carefully. Methinks
perl is probably better at this. Hint hint..

The git-update-server-info command prepares informational files
to help clients discover the contents of a repository, and pull
from it via a dumb transport protocols. Currently, the
following files are produced.
- The $repo/info/refs file lists the name of heads and tags
available in the $repo/refs/ directory, along with their
SHA1. This can be used by git-ls-remote command running on
the client side.
- The $repo/info/rev-cache file describes the commit ancestry
reachable from references in the $repo/refs/ directory. This
file is in an append-only binary format to make the server
side friendly to rsync mirroring scheme, and can be read by
git-show-rev-cache command.
- The $repo/objects/info/pack file lists the name of the packs
available, the interdependencies among them, and the head
commits and tags contained in them. Along with the other two
files, this is designed to help clients to make smart pull
decisions.
The git-receive-pack command is changed to invoke it at the end,
so just after a push to a public repository finishes via "git
push", the server info is automatically updated.
In addition, building of the rev-cache file can be done by a
standalone git-build-rev-cache command separately.

Retrieve and list the remote refs from git, http, and rsync
repositories, and optionally stores the retrieved refs in the
local repository under the same name.
To access a git URL, git-peek-remote command is used. An http
URL needs to have an up-to-date info/refs file for discovery,
which will be introduced by a later update-server-info patch.

Add a git-peek-remote command that talks with upload-pack the
same way git-fetch-pack and git-clone-pack do, to show the
references the remote side has on the standard output.
A later patch introduces git-ls-remote that implements a UI to
store tag values retrieved using this command.

Since pull and fetch are done often against the same remote
repository repeatedly, keeping the URL to pull from along with
the name of the head to use in $GIT_DIR/branches/$name makes a
lot of sense. Adopt that convention from Cogito, and try to be
compatible when possible; storing a partial URL and completing
it with a trailing path may not be understood by Cogito.
While we are at it, fix pulling a tag. Earlier, we updated only
refs/tags/$tag without updating FETCH_HEAD, and called
resolve-script using a stale (or absent) FETCH_HEAD.

Now, not all projects can be as refined as Linux. Before the final 1.0
release, we went through fifteen 0.99 patchfiles, and pl14 alone went
through subreleases 'a' through 'z'. Now _that_ is a release process.
Not to mention the odd-ball releases, like 0.96c+
Sadly, in this day and age of RPM's etc, we have silly limitations, and
I cannot call this release '0.99pl5a or some such awe-inspiring name
just because "rpmbuild" is such a party pooper. So it's just 0.99.1.
Oh well. Aspiring to such greatness as the Linux release numbering is
hubris anyway. You can attain such perfection only once in your life.

Sharing code between shell scripts and C is a challenge. The program
git-var allows us to have a set of named values that a shell script can
interrogate and a normal C program can simply call the functions that
compute them. Allowing sharing when computing plain test values.

.. and does a "git-upload-pack" on demand.

We'll want to use it for the tagging too.

There's a few generated files that we left behind.
|

That way we avoid any confusion with "GNU Interactive Tools", and it's
more descriptive anyway (the rpm documentation talks about how git is
split into a "core" part and an "SCM" part, this makes it clear that
this is the core one).

You can use it as
git branch <branchname> [start-point]
and it creates a new branch of name <branchname>. If a starting point
is specified, that will be where the branch is created, otherwise it
will be created at the current HEAD.
The sequence
git branch xyz abc
git checkout xyz
can also be written as
git checkout -b xyz abc
as per the previous commit.

This patch makes the first half of write_sha1_file() and
index_fd() externally visible, to allow callers to compute the
object ID without actually storing it in the object database.
[JC demangled the whitespaces himself because he liked the patch
so much, and reworked the interface to index_fd() slightly,
taking suggestion from Linus and of his own.]

I'm bored with doing it by hand all the time.

It only does local and ssh pushes, because it's really just a wrapper
for git-send-pack. We might make it do an rsync mirror or something, of
course.

It sets up the normal git environment variables and a few helper
functions (currently just "die()"), and returns ok if it all looks like
a git archive. So use it something like
. git-sh-setup-script || die "Not a git archive"

This was invaluable for debugging the zero-sized compression issue, and
might be useful for scripting too, if people want to see the contents of
a pack.

It's meant to be used by "git fetch" for the local and ssh case.
It doesn't actually do the fetching now, but it does discover the common
commit point.
|

I want to use it for git-fetch-pack too.
|
|
This, together with "git repack" can be used to clean up unpacked
git archives.

We're pretty sparse-clean already, thanks to earlier efforts, but some

Nico pointed out that having verify_pack.c and verify-pack.c was
confusing. Rename verify_pack.c to pack-check.c as suggested,
and enhances the verification done quite a bit.
- Built-in sha1_file unpacking knows that a base object of a
deltified object _must_ be in the same pack, and takes
advantage of that fact.
- Earlier verify-pack command only checked the SHA1 sum for the
entire pack file and did not look into its contents. It now
checks everything idx file claims to have unpacks correctly.
- It now has a hook to give more detailed information for
objects contained in the pack under -v flag.

It got turned off by mistake just because I had been doing debugging,

Like git-receive-pack, this is only partway done.
|
|
It's not working yet, but it's at the point where I want to be able to
track my changes. The theory of operation is that this is the "remote"
side of a "git push". It can tell us what references the remote side
has, receives out reference update commands and a pack-file, and can
execute the unpacking command.
|

Given a list of <pack>.idx files, this command validates the
index file and the corresponding .pack file for consistency.
This patch also uses the same validation mechanism in fsck-cache
when the --full flag is used.
During normal operation, sha1_file.c verifies that a given .idx
file matches the .pack file by comparing the SHA1 checksum
stored in .idx file and .pack file as a minimum sanity check.
We may further want to check the pack signature and version when
we map the pack, but that would be a separate patch.
Earlier, errors to map a pack file was not flagged fatal but led
to a random fatal error later. This version explicitly die()s
when such an error is detected.

This makes it match the new delta encoding, and admittedly makes the
code easier to follow.
This also updates the PACK file version to 2, since this (and the delta
encoding change in the previous commit) are incompatible with the old
format.
|
|
|
|
Packed delta files created by git-pack-objects seems to be the
way to go, and existing "delta" object handling code has exposed
the object representation details to too many places. Remove it
while we refactor code to come up with a proper interface in
sha1_file.c.

We want to be able to check their integrity later, and putting the
sha1-sum of the contents at the end is a good thing. The writing
routines are generic, so we could try to re-use them for the index file,
instead of having the same logic duplicated.
Update unpack-objects to know about the extra 20 bytes at the end
of the index.

This will scan 2 or more object repositories and look for common objects, check
if they are hardlinked, and replace one with a hardlink to the other if not.
This version warns when skipping files because of size differences, and
handle more than 2 repositories automatically.

The git-cherry command helps the git-rebase script by finding
commits that have not been merged upstream. Commits already
included in upstream are prefixed with '-' (meaning "drop from
my local pull"), while commits missing from upstream are
prefixed with '+' (meaning "add to the updated upstream").

So far it just reads the header and generates the list of objects.
It also sorts them by the order they are written in the pack file,
since that ends up being the same order we got them originally, and
is thus "most recent first".
|
|
This is kind of like a tar-ball for a set of objects, ready to be
shipped off to another end. Alternatively, you could use is as a packed
representation of the object database directly, if you changed
"read_sha1_file()" to read these kinds of packs.
The latter is partiularly useful to generate a "packed history", ie you
could pack up your old history efficiently, but still have it available
(at a performance hit, of course).
I haven't actually written an unpacker yet, so the end result has not
been verified in any way yet. I obviously always write bug-free code,
so it just has to work, no?
