When checking which tags to fetch, the old code used to call
git-show-ref --verify for each remote tag. Since reading even
packed refs is not a cheap operation when there are a lot of
local refs, the code became quite slow.
This fixes it by teaching git-show-ref to filter out existing
refs using a new mode of operation of git-show-ref.

When using symmetric differences, I think the user almost always
would want to know which side of the symmetry each commit came
from. So this removes --left-right option from the command
line, and turns it on automatically when a symmetric difference
is used ("git log --merge" counts as a symmetric difference
between HEAD and MERGE_HEAD).
Just in case, a new option --no-left-right is provided to defeat
this, but I do not know if it would be useful.

The output from "symmetric diff", i.e. A...B, does not
distinguish between commits that are reachable from A and the
ones that are reachable from B. In this picture, such a
symmetric diff includes commits marked with a and b.
x---b---b branch B
/ \ /
/ .
/ / \
o---x---a---a branch A
However, you cannot tell which ones are 'a' and which ones are
'b' from the output. Sometimes this is frustrating. This adds
an output option, --left-right, to rev-list.
rev-list --left-right A...B
would show ones reachable from A prefixed with '<' and the ones
reachable from B prefixed with '>'.
When combined with --boundary, boundary commits (the ones marked
with 'x' in the above picture) are shown with prefix '-', so you
would see list that looks like this:
git rev-list --left-right --boundary --pretty=oneline A...B
>bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb 3rd on b
>bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb 2nd on b
<aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 3rd on a
<aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 2nd on a

If GIT_COMMITTER_NAME is not available in receive-pack but reflogs
are enabled we would normally die out with an error message asking
the user to correct their environment settings.
Now that reflogs are enabled by default in (what we guessed to be)
non-bare Git repositories this may cause problems for some users
who don't have their full name in the gecos field and who don't
have access to the remote system to correct the problem.
So rather than die()'ing out in receive-pack when we try to log a
ref change and have no committer name we default to the username,
as obtained from the host's password database.

Everybody hated the pull behaviour of merging the first branch
listed on remotes/* file (or remote.*.fetch config) into the
current branch. This finally corrects that UI wart by
forbidding "git pull" without an explicit branch name on the
command line or branch.$current.merge for the current branch.
The matching change to git-clone was made to prepare the default
branch.*.merge entry for the primary branch some time ago.
Signed-off-by: Junio C Hamano <junkio@cox.net>
This stops enumerating the set of branches found on the remote
side when a clone was made in the configuration file. Instead,
a single entry that maps each remote branch to the local
tracking branch for the remote under the same name is created.
Doing it this way not only shortens the configuration file, but
automatically adjusts to a new branch added on the remote side
after the clone is made.
Unfortunately this cannot be done for the traditional layout,
where we always need to special case the 'master' to 'origin'
mapping within the local branch namespace. But that is Ok; it
will be going away before v1.5.0.
We could also lose the "primary branch" mapping at the
beginning, but that has to wait until we implement the "forbid
'git pull' when we do not have branch.$current.merge for the
current branch" policy we earlier discussed. That should also
be in v1.5.0

Now that 'git add' is considered a first-class UI for 'update-index'
and that the 'git add' documentation states "Even modified files
must be added to the set of changes about to be committed" we should
make the output of 'git status' align with that documentation and
common usage.
So now we see a status output such as:
# Added but not yet committed:
# (will commit)
#
# new file: x
#
# Changed but not added:
# (use "git add file1 file2" to include for commit)
#
# modified: x
#
# Untracked files:
# (use "git add" on files to include for commit)
#
# y
which just reads better in the context of using 'git add' to
manipulate a commit (and not a checkin, whatever the heck that is).
We also now support 'color.status.added' as an alias for the existing
'color.status.updated', as this alias more closely aligns with the
current output and documentation.

If a user modifies files and runs 'git commit' (without the very
useful -a option) and they have not yet updated the index they
are probably coming from another SCM-like tool which would perform
the same as 'git commit -a' in this case. Showing the user their
current status and a final line of "nothing to commit" is not very
reassuring, as the user might believe that Git did not recognize
their files were modified.
Instead we can suggest as part of the 'nothing to commit' message
that the user invoke 'git add' to add files to their next commit.

New and experienced Git users alike are finding out too late that
they forgot to enable reflogs in the current repository, and cannot
use the information stored within it to recover from an incorrectly
entered command such as `git reset --hard HEAD^^^` when they really
meant HEAD^^ (aka HEAD~2).
So enable reflogs by default in all future versions of Git, unless
the user specifically disables it with:
[core]
logAllRefUpdates = false
in their .git/config or ~/.gitconfig.
We only enable reflogs in repositories that have a working directory
associated with them, as shared/bare repositories do not have
an easy means to prune away old log entries, or may fail logging
entirely if the user's gecos information is not valid during a push.
This heuristic was suggested on the mailing list by Junio.
Documentation was also updated to indicate the new default behavior.
We probably should start to teach usuing the reflog to recover
from mistakes in some of the tutorial material, as new users are
likely to make a few along the way and will feel better knowing
they can recover from them quickly and easily, without fsck-objects'
lost+found features.

Back in the old days of Git when people messed around with their
GIT_DIR environment variable more often it was nice to know whether
or not git-init-db created a .git directory or used GIT_DIR.
As most users at that time were rather technical UNIXy folk the
message "defaulting to local storage area" made sense to some and
seemed reasonable.
But it doesn't really convey any meaning to the new Git user,
as they don't know what a 'local storage area is' nor do they
know enough about Git to care. It also really doesn't tell the
experienced Git user a whole lot about the command they just ran,
especially if they might be reinitializing an existing repository
(e.g. to update hooks).
So now we print out what we did ("Initialized empty" or
"Reinitialized existing"), what type of repository ("" or "shared"),
and what location the repository will be in ("$GIT_DIR").

The Cygwin folks have done a fine job at creating a POSIX layer
on Windows That Just Works(tm). However it comes with a penalty;
accessing files in the working tree by way of stat/open/mmap can
be slower for diffcore than inflating the data from a blob which
is stored in a packfile.
This performance problem is especially an issue in merge-recursive
when dealing with nearly 7000 added files, as we are loading
each file's content from the working directory to perform rename
detection. I have literally seen (and sadly watched) paint dry in
less time than it takes for merge-recursive to finish such a merge.
On the other hand this very same merge runs very fast on Solaris.
If Git is compiled with NO_FAST_WORKING_DIRECTORY set then we will
avoid looking at the working directory when the blob in question
is available within a packfile and the caller doesn't need the data
unpacked into a temporary file.
We don't use loose objects as they have the same open/mmap/close
costs as the working directory file access, but have the additional
CPU overhead of needing to inflate the content before use. So it
is still faster to use the working tree file over the loose object.
If the caller needs the file data unpacked into a temporary file
its likely because they are going to call an external diff program,
passing the file as a parameter. In this case reusing the working
tree file will be faster as we don't need to inflate the data and
write it out to a temporary file.
The NO_FAST_WORKING_DIRECTORY feature is enabled by default on
Cygwin, as that is the platform which currently appears to benefit
the most from this option.

Sometimes it is asked on the list how to revert selected path in

affects the working tree files has been available in the form of
"git checkout <tree> -- <paths>...".
By definition --soft would never affect either the index nor the

When comparing file contents during the second loop through a rename

Unfortunately we still have to at least initialize the sizes of the
