Reachability bitmaps do not work with shallow operations,
because they cache a view of the object reachability that
represents the true objects. Whereas a shallow repository
(or a shallow operation in a repository) is inherently
cutting off the object graph with a graft.
We explicitly disallow the use of bitmaps in shallow
repositories by checking is_repository_shallow(), and we
should continue to do that. However, we also want to
disallow bitmaps when we are serving a fetch to a shallow
client, since we momentarily take on their grafted view of
the world.
It used to be enough to call is_repository_shallow at the
start of pack-objects. Upload-pack wrote the other side's
shallow state to a temporary file and pointed the whole
pack-objects process at this state with "git --shallow-file",
and from the perspective of pack-objects, we really were
in a shallow repo. But since b790e0f (upload-pack: send
shallow info over stdin to pack-objects, 2014-03-11), we do
it differently: we send --shallow lines to pack-objects over
stdin, and it registers them itself.
This means that our is_repository_shallow check is way too
early (we have not been told about the shallowness yet), and
that it is insufficient (calling is_repository_shallow is
not enough, as the shallow grafts we register do not change
its return value). Instead, we can just turn off bitmaps
explicitly when we see these lines.

Whitespace breakages are checked while the patch is being parsed.
Disable them at the beginning of parse_chunk(), where each
individual patch is parsed, immediately after we learn the name of
the file the patch applies to and before we start parsing the diff
contained in the patch.
One may naively think that we should be able to not just skip the
whitespace checks but simply fast-forward to the next patch without
doing anything once use_patch() tells us that this patch is not
going to be used. But in reality we cannot really skip much of the
parsing in order to do such a "fast-forward", primarily because
parsing "@@ -k,l +m,n @@" lines and counting the input lines is how
we determine the boundaries of individual patches.

We parse each patchfile and find the name of the path the patch
applies to, and then use that name to consult the attribute system
to find the whitespace rules to be used, and also the target file
(either in the working tree or in the index) to replay the changes
against.
Unlike a Git-generated patch, a non-Git patch is taken to have the
pathnames relative to the current working directory. The names
found in such a patch are modified by prepending the prefix by the
prefix_patches() helper function introduced in 56185f49 (git-apply:
require -p<n> when working in a subdirectory., 2007-02-19).
However, this prefixing is done after the patch is fully parsed and
affects only what target files are patched. Because the attributes
are checked against the names found in the patch during the parsing,
not against the final pathname, the whitespace check that is done
during parsing ends up using attributes for a wrong path for non-Git
patches.
Fix this by doing the prefix much earlier, immediately after the
header part of each patch is parsed and we learn the name of the
path the patch affects.

Feeding the result of a real_path() call to real_path() again doesn't
change that result -- the returned path won't get any more real. Avoid
such a double call in set_git_dir_init() and for the same reason stop
calling real_path() before feeding paths to set_git_work_tree(), as the
latter already takes care of that.

We generally want to avoid lookup_unknown_object, because it
results in allocating more memory for the object than may be
strictly necessary.
In this case, it is used to check whether we have an
already-parsed object before calling parse_object, to save
us from reading the object from disk. Using lookup_object
would be fine for that purpose, but we can take it a step
further. Since this code was written, parse_object already
learned the "check lookup_object" optimization, so we can
simply call parse_object directly.

The "struct object" type implements basic object
polymorphism. Individual instances are allocated as
concrete types (or as a union type that can store any
object), and a "struct object *" can be cast into its real
type after examining its "type" enum. This means it is
dangerous to have a type field that does not match the
allocation (e.g., setting the type field of a "struct blob"
to "OBJ_COMMIT" would mean that a reader might read past the
allocated memory).
In most of the current code this is not a problem; the first
thing we do after allocating an object is usually to set its
type field by passing it to create_object. However, the
virtual commits we create in merge-recursive.c do not ever
get their type set. This does not seem to have caused
problems in practice, though (presumably because we always
pass around a "struct commit" pointer and never even look at
the type).
We can fix this oversight and also make it harder for future
code to get it wrong by setting the type directly in the
object allocation functions.
This will also make it easier to fix problems with commit
index allocation, as we know that any object allocated by
alloc_commit_node will meet the invariant that an object
with an OBJ_COMMIT type field will have a unique index
number.

When the user has no user-wide configuration file, it's faster to use the
newly introduced config file template than to run two commands to set
user.name and user.email. Advise this to the user.
The old advice is kept if the user already has a configuration file since
the template feature would not trigger in this case.

When the user has no ~/.gitconfig file, git config --global --edit used
to launch an editor on an nonexistant file name.
Instead, create a file with a default content before launching the
editor. The template contains only commented-out entries, to save a few
keystrokes for the user. If the values are guessed properly, the user
will only have to uncomment the entries.
Advanced users teaching newbies can create a minimalistic configuration
faster for newbies. Beginners reading a tutorial advising to run "git
config --global --edit" as a first step will be slightly more guided for
their first contact with Git.

When parsing "index" lines from a git-diff, we look for a
space followed by the mode. If we don't have a space, then
we set our pointer to the end-of-line. However, we don't
double-check that our end-of-line pointer is valid (e.g., if
we got a truncated diff input), which could lead to some
wrap-around pointer arithmetic.
In most cases this would probably get caught by our "40 <
len" check later in the function, but to be on the safe
side, let's just use strchrnul to treat end-of-string the
same as end-of-line.

When using --graft, with a mergetag in the original

also be misleading. So let's just error out and
