1cb639e6b0 git-submodule summary: show commit summary
This patch does the hard work to show submodule commit summary.

For a modified submodule, a series of commits will be shown with
the following command:

    git log --pretty='format:%m %s' \
        --first-parent sha1_src...sha1_dst

where the sha1_src is from the given super project commit and the
sha1_dst is from the index or working tree (switched by --cached).

For a deleted, added, or typechanged (blob<->submodule) submodule,
only one single newest commit from the existing end (for example,
src end for submodule deleted or type changed from submodule to blob)
will be shown.

If the src/dst sha1 for a submodule is missing in the submodule
directory, a warning will be issued except in two cases where the
submodule directory is deleted (type 'D') or typechanged to blob
(one case of type 'T').

In the title line for a submodule, the src/dst sha1 and the number
of commits (--first-parent) between the two commits will be shown.

The following example demonstrates most cases.

    Example: commit summary for modified submodules sm1-sm5.
    --------------------------------------------
    $ git submodule summary
    * sm1 354cd45...3f751e5 (4):
      < one line message for C
      < one line message for B
      > one line message for D
      > one line message for E

    * sm2 5c8bfb5...000000 (3):
      < one line message for F

    * sm3 354cd45...3f751e5:
      Warn: sm3 doesn't contain commit 354cd45

    * sm4 354cd34(submodule)-> 235efa(blob) (1):
      < one line message for G

    * sm5 354cd34(blob)-> 235efa(submodule) (5):
      > one line message for H

69099d6bed help: implement multi-valued "man.viewer" config option
This allows multiple viewer candidates to be listed in the configuration
file, like this:

        [man]
                viewer = woman
                viewer = konqueror
                viewer = man

The candidates are tried in the order listed in the configuration file,
and the first suitable one (e.g. konqueror cannot be used outside windowed
environment) is used.

As the result, the user will see something like this:

this:

28f9af5d25 git-submodule summary: code framework
These patches teach git-submodule a new subcommand 'summary' to show
commit summary of checked out submodules between a given super project
commit (defaults to HEAD) and working tree (or index, when --cached is
given).

This patch just introduces the framework to find submodules which have
summary to show. A submodule will have summary if it falls into these
cases:

  - type 'M': modified and checked out    (1)
  - type 'A': added and checked out       (2)
  - type 'D': deleted
  - type 'T': typechanged (blob <-> submodule)

Notes:

  1. There may be modified but not checked out cases. In the case of a
     merge conflict, even if the submodule is not checked out, there may
	 be still a diff between index and HEAD on the submodule entry
	 (i.e. modified). The summary will not be show for such a submodule.
  2. A similar explanation applies to the added but not checked out case.

fc99469a2b launch_editor(): allow spaces in the filename
The construct

	sh -c "$0 \"$@\"" <editor> <file>

does not pick up quotes in <editor>, so you cannot give path to the
editor that has a shell IFS whitespace in it, and also give it initial
set of parameters and flags.  Replace $0 with <editor> to fix this issue.

This fixes

	git config core.editor '"c:/Program Files/What/Ever.exe"'

In other words, you can specify an editor with spaces in its path using a
config containing something like this:

	[core]
		editor = \"c:/Program Files/Darn/Spaces.exe\"

NOTE: we cannot just replace the $0 with \"$0\", because we still want
this to work:

	[core]
		editor = emacs -nw

than vertical ones so we don't make too big impact on available screen

An interesting side effect of Tk scrollbars is that the "elevator"

scrollbar "elevator" changes as the user scrolls the view up and down.

2d48085661 [PATCH] Add an --argscmd flag to get the list of refs to show
This allows gitk to be used to display a different set of refs each

other porcelain suites, for doing such things as displaying the set of
patches in a patch stack.

The user specifies a command as the argument to the --argscmd option.
The command is run initially and each time the display is refreshed,
and is expected to generate a list of commit IDs, one per line.  Those
commits are appended to the commits passed on the command-line when
constructing the git log command to be executed.

The command is considered to be an attribute of a view, and has its
own field in the saved view, and an edit field in the view editor.

1caeacc1f2 unpack_trees(): minor memory leak fix in unused destination index
This adds a "discard_index(&o->result)" to the failure path, to reclaim
memory from an in-core index we built but ended up not using.

The *big* memory leak comes from the fact that we leak the cache_entry
things left and right. That's a very traditional and deliberate leak:
because we used to build up the cache entries by just mapping them
directly in from the index file (and we emulate that in modern times
by allocating them from one big array), we can't actually free them
one-by-one.

So doing the "discard_index()" will free the hash tables etc, which is
good, and it will free the "istate->alloc" but that is never set on the
result because we don't get the result from the index read. So we don't
actually free the individual cache entries themselves that got created
from the trees.

That's not something new, btw. We never did. But some day we should just
add a flag to the cache_entry() that it's a "free one by one" kind, and
then we could/should do it. In the meantime, this one-liner will fix
*some* of the memory leaks, but not that old traditional one.

34110cd4e3 Make 'unpack_trees()' have a separate source and destination index
We will always unpack into our own internal index, but we will take the
source from wherever specified, and we will optionally write the result
to a specified index (optionally, because not everybody even _wants_ any
result: the index diffing really wants to just walk the tree and index
in parallel).

This ends up removing a fair number more lines than it adds, for the
simple reason that we can now skip all the crud that tried to be
oh-so-careful about maintaining our position in the index as we were
traversing and modifying it.  Since we don't actually modify the source
index any more, we can just update the 'o->pos' pointer without worrying
about whether an index entry got removed or replaced or added to.

bc052d7f43 Make 'unpack_trees()' take the index to work on as an argument
This is just a very mechanical conversion, and makes everybody set it to
'&the_index' before calling, but at least it makes it more explicit
where we work with the index.

The next stage would be to split that index usage up into a 'source' and
a 'destination' index, so that we can unpack into a different index than
we started out from.

d1f128b050 Add 'const' where appropriate to index handling functions
This is in an effort to make the source index of 'unpack_trees()' as
being const, and thus making the compiler help us verify that we only
access it for reading.

The constification also extended to some of the hashing helpers that get
called indirectly.

bcbe5a515e Fix tree-walking compare_entry() in the presense of --prefix
When we make the "root" tree-walk info entry have a pathname in it, we
need to have a ->prev pointer so that compare_entry will actually notice
and traverse into the root.

01904572a5 Move 'unpack_trees()' over to 'traverse_trees()' interface
This not only deletes more code than it adds, it gets rid of a
singularly hard-to-understand function (unpack_trees_rec()), and
replaces it with a set of smaller and simpler functions that use the
generic tree traversal mechanism to walk over one or more git trees in
parallel.

It's still not the most wonderful interface, and by no means is the new
code easy to understand either, but it's at least a bit less opaque.

91e4f03604 Make 'traverse_trees()' traverse conflicting DF entries in parallel
This makes the traverse_trees() entry comparator routine use the more
relaxed form of name comparison that considers files and directories
with the same name identical.

We pass in a separate mask for just the directory entries, so that the
callback routine can decide (if it wants to) to only handle one or the
other type, but generally most (all?) users are expected to really want
to see the case of a name 'foo' showing up in one tree as a file and in
another as a directory at the same time.

In particular, moving 'unpack_trees()' over to use this tree traversal
mechanism requires this.

5803c6f8a2 Add return value to 'traverse_tree()' callback
This allows the callback to return an error value, but it can also
specify which of the tree entries that it actually used up by returning
a positive mask value.

40d934df72 Make 'traverse_tree()' use linked structure rather than 'const char *base'
This makes the calling convention a bit less obvious, but a lot more
flexible.  Instead of allocating and extending a new 'base' string, we
just link the top-most name into a linked list of the 'info' structure
when traversing a subdirectory, and we can generate the basename by
following the list.

Perhaps even more importantly, the linked list of info structures also
gives us a place to naturally save off other information than just the
directory name.
