A short perl script that will walk the tag refs, tag objects, and even commit
objects in its quest to figure out whether the given SHA1 (for a commit or
tree) was ever tagged.
This version is reworked incorporating sanity, feature and style fixes from
Junio.
Object references are used in server-info.c:find_pack_info_one() to
find out which objects in the pack are heads, therefore tracking of
references cannot be disabled.

need a better name, or start allowing dash,"clone.keep-pack"), the packed
data downloaded while cloning is saved as a pack in .git/objects/pack/
locally, with index generated for it with git-index-pack.
This changes the generation of hash packfiles have in their names, from
"hash of object names as fed to us" to "hash of object names in the
resulting pack, in the order they appear in the index file". The new
"git-index-pack" command is taught to output the computed hash value
to its standard output.
With this, we can store downloaded pack in a temporary file without
knowing its final name, run git-index-pack to generate idx for it
while finding out its final name, and then rename the pack and idx to
their final names.
git-index-pack builds a pack index file for an existing packed
archive. With this utility a packed archive which was transferred
without the corresponding pack index can be added to objects/pack/
without repacking.

When feeding patches from standard input, and --interactive is specified,
quit, so that the user can re-run the command, instead of infinitely
looping.
git-fetch --tags: deal with tags with spaces in them.
"git-fetch --tags" can get confused with tags with spaces in their names,
it used to use shell IFS to split the list of tags and also used curl
which insists the URL to be escaped. Fix it so it can work with Martin's
moodle repository http://locke.catalyst.net.nz/git/moodle.git/.
We still reserve characters like leading plus-sign '+' and colon
':' anywhere to represent refspec src-dst pair, and obviously we
cannot use LF (that terminates Pull: line in .git/remotes
files), but now you can have spaces with this patch.
curl_escape ought to do this, but we should not let it quote
slashes (nobody said refs/tags cannot have subdirectories), so
we roll our own safer version. With this, the last part of
git-clone from Martin's moodle repository that used to fail now
works, which reads:
[PATCH] cvsimport: don't pass --cvs-direct if user options contradict us
Detecting if the user passed --no-cvs-direct and don't force the mode.

They always were meant to be case-insensitive, but I had missed one
"tolower()", making that not true.
The actual _values_ aren't case-insensitive, of course, although some uses
of them may be (ie boolean parsing uses "strcasecmp()" to match against
the strings "true" and "false").

Use git config file for committer name and email info
This starts using the "user.name" and "user.email" config variables if
they exist as the default name and email when committing. This means
that you don't have to use the GIT_COMMITTER_EMAIL environment variable
to override your email - you can just edit the config file instead.
The patch looks bigger than it is because it makes the default name and
email information non-static and renames it appropriately. And it moves
the common git environment variables into a new library file, so that
you can link against libgit.a and get the git environment without having
to link in zlib and libcrypt.
In short, most of it is renaming and moving, the real change core is
just a few new lines in "git_default_config()" that copies the user
config values to the new base.
It also changes "git-var -l" to list the config variables.

With "[core] filemode = false", you can tell git to ignore
differences in the working tree file only in executable bit.
* "git-update-index --refresh" does not say "needs update" if index
entry and working tree file differs only in executable bit.
* "git-update-index" on an existing path takes executable bit
from the existing index entry, if the path and index entry are
both regular files.
* "git-diff-files" and "git-diff-index" without --cached flag
pretend the path on the filesystem has the same executable
bit as the existing index entry, if the path and index entry
are both regular files.
If you are on a filesystem with unreliable mode bits, you may need to
force the executable bit after registering the path in the index.
* "git-update-index --chmod=+x foo" flips the executable bit of the
index file entry for path "foo" on. Use "--chmod=-x" to flip it
off.
Note that --chmod only works in index file and does not look at nor
update the working tree.
So if you are on a filesystem and do not have working executable bit,
you would do:
1. set the appropriate .git/config option;
2. "git-update-index --add new-file.c"
3. "git-ls-files --stage new-file.c" to see if it has the desired
mode bits. If not, e.g. to drop executable bit picked up from the
filesystem, say "git-update-index --chmod=-x new-file.c".
I had meant to disallow unknown escape characters in the config file
parser, but instead an unknown escaped character would silently pass
through as itself. That's correct for some cases (notably '\' itself), but
wasn't correct in general.
This fixes it, and makes the parser write a nice error message if the
config file contains bogus escaped characters.

The http commit walker cannot use the same temporary file
creation code because it needs to use predictable temporary
filename for partial fetch continuation purposes, but the code
to move the temporary file to the final location should be
usable from the ordinary object creation codepath.
Export move_temp_to_file from sha1_file.c and use it, while
losing the custom relink_or_rename function from http-fetch.c.
Also the temporary object file creation part needs to make sure
the leading path exists, in preparation of the really lazy
fan-out directory creation.
Restore functionality to allow proxies to cache objects
The parallel request changes didn't properly implement the previous patch to

Add support for parallel HTTP transfers. Prefetch populates a queue of
objects to transfer and starts feeding requests to an active request
queue for processing; fetch_object keeps the active queue moving
while the specified object is being transferred. The size of the active
queue can be restricted using -r and defaults to 5 concurrent transfers.
Requests for objects that are not prefetched are also processed via the
active queue.

This is a first cut at a very simple parser for a git config file.
The format of the file is a simple ini-file like thing, with simple
variable/value pairs. You can (and should) make the variables have a
simple single-level scope, ie a valid file looks something like this:
#
# This is the config file, and
# a '#' or ';' character indicates
# a comment
#
which parses into three variables: "core.filemode" is associated with the
string "false", and "diff.external" gets the appropriate quoted value.
Right now we only react to one variable: "core.filemode" is a boolean that
decides if we should care about the 0100 (user-execute) bit of the stat
information. Even that is just a parsing demonstration - this doesn't
actually implement that st_mode compare logic itself.
Different programs can react to different config options, although they
should always fall back to calling "git_default_config()" on any config
option name that they don't recognize.

The platform specific tweaking part was using 'uname -o' which
is not always available. Squelch error message from it.
It was suggested to chain the if..else, but I chose not to, because
maintaining the nested if..else if..else..endif endif to match is a
pain. If we had "elif", things would have been different, though.
While we are at it, try not to invoke 'uname -s' for each platform
candidate.
Make sure 'make install' does not have to rebuild templates.
The dependency rule in templates directory forced 'make install'
that immediately followed 'make all' to rebuild boilerplates.
This was problematic for a workflow that built first as yourself
and then installed as root, from a working tree that is on an
NFS mounted filesystem that is unwritable by root.
[PATCH] If NO_MMAP is defined, fake mmap() and munmap()

This makes it possible to have a "sparse" git object subdirectory
structure, something that has become much more attractive now that people
use pack-files all the time.
As a result of pack-files, a git object directory doesn't necessarily have
any individual objects lying around, and in that case it's just wasting
space to keep the empty first-level object directories around: on many
filesystems the 256 empty directories will be aboue 1MB of diskspace.
Even more importantly, after you re-pack a project that _used_ to be
unpacked, you could be left with huge directories that no longer contain
anything, but that waste space and take time to look through.
With this change, "git prune-packed" can just do an rmdir() on the
directories, and they'll get removed if empty, and re-created on demand.
This patch also tries to fix up "write_sha1_from_fd()" to use the new
common infrastructure for creating the object files, closing a hole where
we might otherwise leave half-written objects in the object database.
[jc: I unoptimized the part that really removes the fan-out directories
to ease transition. init-db still wastes 1MB of diskspace to hold 256
empty fan-outs, and prune-packed rmdir()'s the grown but empty directories,
but runs mkdir() immediately after that -- reducing the saving from 150KB
to 146KB. These parts will be re-introduced when everybody has the
on-demand capability.]

It reorganizes the code and also has saner command line options

file from the command line, as well as reading from the standard
input when '-' is specified.
Add an new option --show-index-info to git-apply command to

command shows something similar to git-ls-files --stage output
for the pre-change image:
Show original and resulting blob object info in diff output.
This adds more cruft to diff --git header to record the blob SHA1 and
the mode the patch/diff is intended to be applied against, to help the
receiving end fall back on a three-way merge. The new header looks
like this:
diff --git a/apply.c b/apply.c

Upon receiving such a patch, if the patch did not apply cleanly to the
target tree, the recipient can try to find the matching old objects in
her object database and create a temporary tree, apply the patch to
that temporary tree, and attempt a 3-way merge between the patched
temporary tree and the target tree using the original temporary tree
as the common ancestor.
The patch lifts the code to compute the hash for an on-filesystem
object from update-index.c and makes it available to the diff output
routine.
When you are applying 200 mails in sequence, .dotest/ directory
will be littered with many messsages, and when the patch in one
of them fails to apply, it is not obvious which message was
being processed. Remove the one that has been already dealt
with, so that the last failed one is found typically as the
lowest numbered split message.
Fall back to three-way merge when applying a patch.
After git-apply fails, attempt to find a base tree that the patch
cleanly applies to, and do a three-way merge using that base tree into
the current index, if .dotest/.3way file exists. This flag can be
controlled by giving -m flag to git-applymbox command.
When the fall-back merge fails, the working tree can be resolved the
same way as you would normally hand resolve a conflicting merge.
When making commit, use .dotest/final-commit as the log message
template. Or you could just choose to 'git-checkout-index -f -a'
to revert the failed merge.
The current "git tag -s" thing always uses the tagger name as the signing
user key, which is very irritating, since my key is under my email
address, but the tagger key obviously contains the actual machine name
too.
Now, I could just use "GIT_COMMITTER_EMAIL" and force it to be my real
email, but I actually think that it's nice to see which machine I use for
my work.
So rather than force my tagger ID to have to match the gpg key name, just
support the "-u" flag to "git tag" instead. It implicitly enables signing,
since it doesn't make any sense without it. Thus:
git tag -u <gpg-key-name> <tag-name> [<tagged-object>]
will use the named gpg key for signing.

upload-pack: Do not choke on too many heads request.
Cloning from a repository with more than 256 refs (heads and tags
included) will choke, because upload-pack has a built-in limit of
feeding not more than MAX_NEEDS (currently 256) heads to underlying
git-rev-list. This is a problem when cloning a repository with many
tags, like http://www.linux-mips.org/pub/scm/linux.git, which has 290+
tags.
This commit introduces a new flag, --all, to git-rev-list, to include
all refs in the repository. Updated upload-pack detects requests that
ask more than MAX_NEEDS refs, and sends everything back instead.
We may probably want to tweak the definitions of MAX_NEEDS and
MAX_HAS, but that is a separate topic.

git-apply: allow operating in sparsely populated working tree.
This patch teaches 'git-apply --index' to automatically check

Return error when not checking out an entry due to dirtiness.
Without -f flag, 'git-checkout-index foo.c' issued an error message
when foo.c already existed in the working tree and did not match index.
However it did not return an error from the underlying checkout_entry()
function and resulted in a successful exit(0).
There was a leftover use of sed that attempted to remove the commit ID
output from git-diff-tree, which turned into an expensive no-op when
git-diff-tree output header format changed about three months ago.
