stash: default listing to working-tree diff
When you list stashes, you can provide arbitrary git-log
options to change the display. However, adding just "-p"
does nothing, because each stash is actually a merge commit.
This implementation detail is easy to forget, leading to
confused users who think "-p" is not working. We can make
this easier by defaulting to "--first-parent -m", which will
show the diff against the working tree. This omits the
index portion of the stash entirely, but it's simple and it
matches what "git stash show" provides.
People who are more clueful about stash's true form can use
"--cc" to override the "-m", and the "--first-parent" will
then do nothing. For diffs, it only affects non-combined
diffs, so "--cc" overrides it. And for the traversal, we are
walking the linear reflog anyway, so we do not even care
about the parents.

Unlike a Git-generated patch, a non-Git patch is taken to have the

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

files to be parsed several times during the run of a git program, with
different callbacks picking out different variables useful to themselves.
Add a `config_set`, that can be used to construct an in-memory cache for

`~/.gitconfig` etc.). Add two external functions `git_configset_get_value`
and `git_configset_get_value_multi` for querying from the config sets.
`git_configset_get_value` follows `last one wins` semantic (i.e. if there
are multiple matches for the queried key in the files of the configset the
value returned will be the last entry in `value_list`).
`git_configset_get_value_multi` returns a list of values sorted in order of
increasing priority (i.e. last match will be at the end of the list). Add
type specific query functions like `git_configset_get_bool` and similar.
Add a default `config_set`, `the_config_set` to cache all key-value pairs
read from usual config files (repo specific .git/config, user wide
~/.gitconfig, XDG config and the global /etc/gitconfig). `the_config_set`
is populated using `git_config()`.

`git_config_get_value_multi` for querying in a non-callback manner from

add object_as_type helper for casting objects
When we call lookup_commit, lookup_tree, etc, the logic goes
something like:
1. Look for an existing object struct. If we don't have
one, allocate and return a new one.
2. Double check that any object we have is the expected
type (and complain and return NULL otherwise).
3. Convert an object with type OBJ_NONE (from a prior
call to lookup_unknown_object) to the expected type.
We can encapsulate steps 2 and 3 in a helper function which
checks whether we have the expected object type, converts
OBJ_NONE as appropriate, and returns the object.
Not only does this shorten the code, but it also provides
one central location for converting OBJ_NONE objects into
objects of other types. Future patches will use that to
enforce type-specific invariants.
Since this is a refactoring, we would want it to behave
exactly as the current code. It takes a little reasoning to
see that this is the case:
- for lookup_{commit,tree,etc} functions, we are just
pulling steps 2 and 3 into a function that does the same
thing.
- for the call in peel_object, we currently only do step 3
(but we want to consolidate it with the others, as
mentioned above). However, step 2 is a noop here, as the
surrounding conditional makes sure we have OBJ_NONE
(which we want to keep to avoid an extraneous call to
sha1_object_info).
- for the call in lookup_commit_reference_gently, we are
currently doing step 2 but not step 3. However, step 3
is a noop here. The object we got will have just come
from deref_tag, which must have figured out the type for

move setting of object->type to alloc_* functions
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.

alloc.c: remove the alloc_raw_commit_node() function
In order to encapsulate the setting of the unique commit index, commit 969eba63 ("commit: push commit_index update into alloc_commit_node",
10-06-2014) introduced a (logically private) intermediary allocator
function. However, this function (alloc_raw_commit_node()) was declared
as a public function, which undermines its entire purpose.
Introduce an inline function, alloc_node(), which implements the main
logic of the allocator used by DEFINE_ALLOCATOR, and redefine the macro
in terms of the new function. In addition, use the new function in the
implementation of the alloc_commit_node() allocator, rather than the
intermediary allocator, which can now be removed.
Noticed by sparse ("symbol 'alloc_raw_commit_node' was not declared.
Should it be static?").

commit: advertise config --global --edit on guessed identity
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.

home_config_paths(): let the caller ignore xdg path
The caller can signal that it is not interested in learning
the location of $HOME/.gitconfig by passing global=NULL, but
there is no way to decline the path to the configuration
file based on $XDG_CONFIG_HOME.
Allow the caller to pass xdg=NULL to signal that it is not
interested in the XDG location.

config --global --edit: create a template file if needed
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.

apply: avoid possible bogus pointer
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.

fix memory leak parsing core.commentchar
When we see the core.commentchar config option, we extract
the string with git_config_string, which does two things:
1. It complains via config_error_nonbool if there is no
string value.
2. It makes a copy of the string.
Since we immediately parse the string into its
single-character value, we only care about (1). And in fact
(2) is a detriment, as it means we leak the copy. Instead,
let's just check the pointer value ourselves, and parse
directly from the const string we already have.

free ref string returned by dwim_ref
A call to "dwim_ref(name, len, flags, &ref)" will allocate a
new string in "ref" to return the exact ref we found. We do
not consistently free it in all code paths, leading to small
leaks. The worst is in get_sha1_basic, which may be called
many times (e.g., by "cat-file --batch"), though it is
relatively unlikely, as it only triggers on a bogus reflog
specification.
