Paul Tan [Tue, 21 Apr 2015 04:06:27 +0000 (12:06 +0800)] 
path.c: implement xdg_config_home()

The XDG base dir spec[1] specifies that configuration files be stored in
a subdirectory in $XDG_CONFIG_HOME. To construct such a configuration
file path, home_config_paths() can be used. However, home_config_paths()
combines distinct functionality:

1. Retrieve the home git config file path ~/.gitconfig

2. Construct the XDG config path of the file specified by `file`.

This function was introduced in commit 21cf3227 ("read (but not write)
from $XDG_CONFIG_HOME/git/config file").  While the intention of the
function was to allow the home directory configuration file path and the
xdg directory configuration file path to be retrieved with one function
call, the hard-coding of the path ~/.gitconfig prevents it from being
used for other configuration files. Furthermore, retrieving a file path
relative to the user's home directory can be done with
expand_user_path(). Hence, it can be seen that home_config_paths()
introduces unnecessary complexity, especially if a user just wants to
retrieve the xdg config file path.

As such, implement a simpler function xdg_config_home() for constructing
the XDG base dir spec configuration file path. This function, together
with expand_user_path(), can replace all uses of home_config_paths().

git-compat-util.h: implement a different ARRAY_SIZE macro for for safely deriving the size of array

To get number of elements in an array git use the ARRAY_SIZE macro
defined as:

       #define ARRAY_SIZE(x) (sizeof(x)/sizeof((x)[0]))

The problem with it is a possibility of mistakenly passing to it a
pointer instead an array. The ARRAY_SIZE macro as conventionally
defined does not provide good type-safety and the open-coded
approach is more fragile, more verbose and provides no improvement in
type-safety.

Use instead a different but compatible ARRAY_SIZE() macro,
which will also break compile if you try to
use it on a pointer. This implemention revert to the original code
if the compiler doesn't know the typeof and __builtin_types_compatible_p
GCC extensions.

This can ensure our code is robust to changes, without
needing a gratuitous macro or constant. A similar
ARRAY_SIZE implementation also exists in the linux kernel.

pathspec: avoid the need of "--" when wildcard is used

When "--" is lacking from the command line and a command can take
both revs and paths, the idea is if an argument can be seen as both
an extended SHA-1 and a path, then "--" is required or git refuses
to continue. It's currently implemented as:

 (1) if an argument is rev, then it must not exist in worktree

 (2) else, it must exist in worktree

 (3) else, "--" is required.

These rules work for literal paths, but when non-literal pathspec is
involved, it almost always requires the user to add "--" because it
fails (2) and (1) is really rarely met (take "*.c" for example, (1)
is met if there is a ref named "*.c").

This patch modifies the rules a bit by considering any valid (*)
wildcard pathspec "exist in worktree". The rules become:

 (1) if an arg is a rev, then it must either exist in worktree or
     not be a valid wildcard pathspec.

 (2) else, it either exists in worktree or is a wildcard pathspec

 (3) else, "--" is required.

With the new rules, "--" is not needed most of the time when
wildcard pathspec is involved.

the working directory is clean.  This is because the commit removed
the conversion in blame.c for all files, with or without CRLF in the

Having files with CRLF in the repo and core.autocrlf=input is a

    [This] syntax (<msg> `HEAD` <commit>...) is supported for

 2. filtering these parents into independent ones; and

 3. optionally calling fmt_merge_msg() via prepare_merge_message()

    contents that FETCH_HEAD would have had if these commits were
    fetched from the current repository with "git pull . $args..."

Make "git merge FETCH_HEAD" to be the same as the traditional

    git merge "$(git fmt-merge-msg <.git/FETCH_HEAD)" $commits

invocation of the command in "git pull", where $commits are the ones
that appear in FETCH_HEAD that are not marked as not-for-merge, by
making it do a bit more, specifically:

 - noticing "FETCH_HEAD" is the only "commit" on the command line
   and picking the commits that are not marked as not-for-merge as
   the list of commits to be merged (substitute for step #1 above);

 - letting the resulting list fed to step #2 above;

 - doing the step #3 above, using the contents of the FETCH_HEAD
   instead of fake contents crafted from the list of commits parsed
   in the step #1 above.

Note that this changes the semantics.  "git merge FETCH_HEAD" has
always behaved as if the first commit in the FETCH_HEAD file were
directly specified on the command line, creating a two-way merge
whose auto-generated merge log said "merge commit xyz".  With this
change, if the previous fetch was to grab multiple branches (e.g.
"git fetch $there topic-a topic-b"), the new world order is to
create an octopus, behaving as if "git pull $there topic-a topic-b"
were run.  This is a deliberate change to make that happen, and
