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").

If receive.denyNonFastforwards is set to true, git-receive-pack will deny
non fast-forwards, i.e. forced updates. Most notably, a push to a repository
which has that flag set will fail.
As a first user, 'git-init-db --shared' sets this flag, since in a shared
setup, you are most unlikely to want forced pushes to succeed.

The old code used to totally mix up the notion of a ref-name and the path
that that ref was associated with. That was not only horribly ugly (a
number of users got the path, and then wanted to try to turn it back into
a ref-name again), but it fundamnetally doesn't work at all once we do any
setup where a ref doesn't have a 1:1 relationship with a particular
pathname.
This fixes things up so that we use the ref-name throughout, and only
turn it into a pathname once we actually look it up in the filesystem.
That makes a lot of things much clearer and more straightforward.

The only change in behaviour should be having a "usage: " prefix
on the output string rather than "fatal: ", and an exit code of

This changes the calling convention of built-in commands and
passes the "prefix" (i.e. pathname of $PWD relative to the

This enhances core.sharedrepository to have additionally
specify that read and exec permissions to be given to others as
well. It is useful when serving a repository via gitweb and
git-daemon that runs as a user outside the project group.
The configuration item can take the following values:
[core]
sharedrepository ; the same as "group"
sharedrepository = true ; ditto
sharedrepository = 1 ; ditto
sharedrepository = group ; allow rwx to group
sharedrepository = all ; allow rwx to group, allow rx to other
sharedrepository = umask ; not shared - use umask
It also extends "git init-db" to take "--shared=all" and friends
from the command line.

There were a few calls to adjust_shared_perm() that were
missing:
- init-db creates refs, refs/heads, and refs/tags before
reading from templates that could specify sharedrepository in
the config file;
- updating config file created it under user's umask without
adjusting;
- updating refs created it under user's umask without
adjusting;
- switching branches created .git/HEAD under user's umask
without adjusting.
This moves adjust_shared_perm() from sha1_file.c to path.c,
since a few SIMPLE_PROGRAM need to call repository configuration
functions which in turn need to call adjust_shared_perm().
sha1_file.c needs to link with SHA1 computation library which
is usually not linked to SIMPLE_PROGRAM.

Basically this just renames init-db.c to builtin-init-db.c and makes
some strings const.
