That NULL unfortunately gets passed into xstrdup() next, resulting in

which will let us emit the correct error message.

A git daemon that starts as "root" and then drops privilege often
leaves $HOME set to that of the root user, which is unreadable by
the daemon process, which was diagnosed as a configuration error.
Make per-user configuration files that are inaccessible due to
EACCES as though these files do not exist to avoid this issue, as
the tightening which was originally meant as an additional security
has annoyed enough sysadmins.

With this change, the output of the push (with push.default set to
current) changes subtly from:
$ git push
...
* [new branch] HEAD -> push-current-head
to:
$ git push
...
* [new branch] push-current-head -> push-current-head
This patch was written with a different motivation. There is a problem
unique to push.default = current:
# on branch push-current-head
$ git push
# on another terminal
$ git checkout master
# return to the first terminal
# the push tried to push master!
This happens because the 'git checkout' on the second terminal races
with the 'git push' on the first terminal. Although this patch does not
solve the core problem (there is still no guarantee that 'git push' on
the first terminal will resolve HEAD before 'git checkout' changes HEAD
on the second), it works in practice.

Setting push.default to current adds the refspec "HEAD" for the
transport layer to handle. If "HEAD" doesn't resolve to a branch (and
since no refspec rhs is specified), the push fails after some time with
a cryptic error message:
$ git push
error: unable to push to unqualified destination: HEAD
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to 'git@github.com:artagnon/git'
Fail early with a nicer error message:
$ git push

With push.default set to upstream or simple, and a detached HEAD, git

$ git push
fatal: You are not currently on a branch.
To push the history leading to the current (detached HEAD)

git-merge-tree causes a null pointer dereference when a directory
entry exists in only one or two of the three trees being compared with
no corresponding entry in the other tree(s).
When this happens, we want to handle the entry as a directory and not
attempt to mark it as a file merge. Do this by setting the entries bit
in the directory mask when the entry is missing or when it is a
directory, only performing the file comparison when we know that a file
entry exists.

In preparation for Git 2.0, "git add -u/-A" without pathspec checks
all the working tree (not limited to the current directory) and
issues a warning when it finds any path that we might add in Git
2.0, because that would mean the users' fingers need to be trained
to explicitly say "." if they want to keep the current behaviour.
However, the check was incomplete, because "git add" usually does
not refresh the index, considers a path that is stat-dirty but has
contents that is otherwise up-to-date in the index as "we might
add", and relies on that it is a no-op to add the same thing again
via the add_file_to_index() API (which also knows not to say "added"
in verbose mode when this happens). We do not want to trigger the
warning for a path that is outside the current directory is merely
stat-dirty, as it won't be added in Git 2.0, either.

In the historical context of "git add --all ." that pays attention
to "all kinds of changes" (implying "without ignoring removals"),
the option to countermand it "--no-all" may have made sense, but
because we will be making "--all" the default when a pathspec is
given, it makes more sense to rename the option to a more explicit
"--ignore-removal". The "--all" option naturally becomes its
negation, "--no-ignore-removal".

The DWIM mode of checkout allows you to run "git checkout foo" when there
is no existing local ref or path called "foo", and there is exactly _one_
remote with a remote-tracking branch called "foo". Git will automatically
create a new local branch called "foo" using the remote-tracking "foo" as
its starting point and configured upstream.
For example, consider the following unconventional (but perfectly valid)
remote setup:
[remote "origin"]
fetch = refs/heads/*:refs/remotes/origin/*
[remote "frotz"]
fetch = refs/heads/*:refs/remotes/frotz/nitfol/*
Case 1: Assume both "origin" and "frotz" have remote-tracking branches called
"foo", at "refs/remotes/origin/foo" and "refs/remotes/frotz/nitfol/foo"
respectively. In this case "git checkout foo" should fail, because there is
more than one remote with a "foo" branch.
Case 2: Assume only "frotz" have a remote-tracking branch called "foo". In
this case "git checkout foo" should succeed, and create a local branch "foo"
from "refs/remotes/frotz/nitfol/foo", using remote branch "foo" from "frotz"
as its upstream.
The current code hardcodes the assumption that all remote-tracking branches
must match the "refs/remotes/$remote/*" pattern (which is true for remotes
with "conventional" refspecs, but not true for the "frotz" remote above).
When running "git checkout foo", the current code looks for exactly one ref
matching "refs/remotes/*/foo", hence in the above example, it fails to find
"refs/remotes/frotz/nitfol/foo", which causes it to fail both case #1 and #2.
The better way to handle the above example is to actually study the fetch
refspecs to deduce the candidate remote-tracking branches for "foo"; i.e.
assume "foo" is a remote branch being fetched, and then map "refs/heads/foo"
through the refspecs in order to get the corresponding remote-tracking
branches "refs/remotes/origin/foo" and "refs/remotes/frotz/nitfol/foo".
Finally we check which of these happens to exist in the local repo, and
if there is exactly one, we have an unambiguous match for "git checkout foo",
and may proceed.
This fixes most of the failing tests introduced in the previous patch.

Since commit a22e6f8 (receive-pack: send pack-processing
stderr over sideband, 2012-09-21), receive-pack will start
an async sideband thread to copy the stderr from our
index-pack or unpack-objects child to the client. We hand
the thread's input descriptor to unpack(), which puts it in
the "err" member of the "struct child_process".
After unpack() returns, we use finish_async() to reap the
sideband thread. The thread is only ready to die when it
gets EOF on its pipe, which is connected to the err
descriptor. So we expect all of the write ends of that pipe
to be closed as part of unpack().
Normally, this works fine. After start_command forks, it
closes the parent copy of the descriptor. Then once the
child exits (whether it was successful or not), that closes
the only remaining writer.
However, there is one code-path in unpack() that does not
handle this. Before we decide which of unpack-objects or
index-pack to use, we read the pack header ourselves to see
how many objects it contains. If there is an error here, we
exit without running either sub-command, the pipe descriptor
remains open, and we are in a deadlock, waiting for the
sideband thread to die (which is in turn waiting for us to
close the pipe).
We can fix this by making sure that unpack() always closes
the pipe before returning.
