Instead of passing --template explicitely to init-db and clone, you can
just set the environment variable GIT_TEMPLATE_DIR.

Also make use of it in the tests, to make sure that the templates are
copied.

This reverts commit 74d20040.
Version from Johannes to introduce GIT_TEMPLATE_DIR is simpler,
although I unconsciously stayed away from introducing yet another
environment variable.

The initial t/trash repository for testing was created properly
but over time we gained many tests that create secondary test
repositories with init-db or clone and they were not careful
enough.

This fixes it.

The remote server might not want to tell why it doesn't like us for

An earlier optimization for --verify broke a lot of stuff
because it did not take interaction with other flags into
account.

This also fixes an unrelated argument parsing error; --hash=8
should mean the same as "--hash --abbrev=8".

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.

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.

When replacing an existing file A with a directory A that has a
file A/B in it in the index, 'update-index --replace --add A/B'
did not properly remove the file to make room for the new
directory.

There was a trivial logic error, most likely a cut & paste one,
dating back to quite early days of git.

When replacing an existing file A with a directory A that has a
file A/B in it in the index, 'git add' did not succeed because
it forgot to pass the allow-replace flag to add_cache_entry().

It might be safer to leave this as an error and require the user
to explicitly remove the existing A first before adding A/B
since it is an unusual case, but doing that automatically is
much easier to use.

When you remove a directory D that has a tracked file D/F out of the
way to create a file D and try to "git update-index --add D", it used
to say "cannot add" which was not very helpful.  This issues an extra
error message to explain the situation before the final "fatal" message.

Since D/F conflicts are relatively rare event, extra verbosity would
not make things too noisy.

Finally.

The separate-remote layout is so much more organized than
traditional and easier to work with especially when you need to
deal with remote repositories with multiple branches and/or you
need to deal with more than one remote repositories, and using
traditional layout for new repositories simply does not make
much sense.

Internally we still have code for 1:1 mappings to create a bare
clone; that is a good thing and will not go away.

Now we lost the "first refspec is the one that is merged by default"
rule, there is no reason for clone to list the remote primary branch
in the config file explicitly anymore.

We still need it for the traditional layout for other reasons,
though.

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: NJunio 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

Add a kind of "next" view in the bottom part of navigation bar for
"commit" view, similar to what was added for "commitdiff" view in
commit 151602df
  'gitweb: Add "next" link to commitdiff view'

For "commit" view for single parent commit:
  (parent: _commit_)
For "commit" view for merge (multi-parent) commit:
  (merge: _commit_ _commit_ ...)
For "commit" view for root (parentless) commit
  (initial)
where _link_ denotes hyperlink.  SHA1 of commit is shortened
to 7 characters on display.

While at it, remove leftovers from commit cae1862a by Petr Baudis:
  'gitweb: More per-view navigation bar links'
namely the "blame" link if there exist $file_name and commit has a
parent; it was added in git_commit probably by mistake.  The rest
of what mentioned commit added for git_commit was removed in
commit 6e0e92fd by Luben Tuikov:
  'gitweb: Do not print "log" and "shortlog" redundantly in commit view'
(which should have probably removed also this "blame" link removed now).
