When diffing binary files, it is sometimes nice to see the
differences of a canonical text form rather than either a
binary patch or simply "binary files differ."
Until now, the only option for doing this was to define an
external diff command to perform the diff. This was a lot of
work, since the external command needed to take care of
doing the diff itself (including mode changes), and lost the
benefit of git's colorization and other options.
This patch adds a text conversion option, which converts a
file to its canonical format before performing the diff.
This is less flexible than an arbitrary external diff, but
is much less work to set up. For example:
$ echo '*.jpg diff=exif' >>.gitattributes
$ git config diff.exif.textconv exiftool
$ git config diff.exif.binary false
allows one to see jpg diffs represented by the text output
of exiftool.

The "diff" gitattribute is somewhat overloaded right now. It
can say one of three things:
1. this file is definitely binary, or definitely not
(i.e., diff or !diff)
2. this file should use an external diff engine (i.e.,
diff=foo, diff.foo.command = custom-script)
3. this file should use particular funcname patterns
(i.e., diff=foo, diff.foo.(x?)funcname = some-regex)
Most of the time, there is no conflict between these uses,
since using one implies that the other is irrelevant (e.g.,
an external diff engine will decide for itself whether the
file is binary).
However, there is at least one conflicting situation: there
is no way to say "use the regular rules to determine whether
this file is binary, but if we do diff it textually, use
this funcname pattern." That is, currently setting diff=foo
indicates that the file is definitely text.
This patch introduces a "binary" config option for a diff
driver, so that one can explicitly set diff.foo.binary. We
default this value to "don't know". That is, setting a diff
attribute to "foo" and using "diff.foo.funcname" will have
no effect on the binaryness of a file. To get the current
behavior, one can set diff.foo.binary to true.
This patch also has one additional advantage: it cleans up
the interface to the userdiff code a bit. Before, calling
code had to know more about whether attributes were false,
true, or unset to determine binaryness. Now that binaryness
is a property of a driver, we can represent these situations
just by passing back a driver struct.

Both sets of code assume that one specifies a diff profile
as a gitattribute via the "diff=foo" attribute. They then
pull information about that profile from the config as
diff.foo.*.
The code for each is currently completely separate from the
other, which has several disadvantages:
- there is duplication as we maintain code to create and
search the separate lists of external drivers and
funcname patterns
- it is difficult to add new profile options, since it is
unclear where they should go
- the code is difficult to follow, as we rely on the
"check if this file is binary" code to find the funcname
pattern as a side effect. This is the first step in
refactoring the binary-checking code.
This patch factors out these diff profiles into "userdiff"
drivers. A file with "diff=foo" uses the "foo" driver, which
is specified by a single struct.
Note that one major difference between the two pieces of
code is that the funcname patterns are always loaded,
whereas external drivers are loaded only for the "git diff"
porcelain; the new code takes care to retain that situation.

format-patch is most commonly used for multiple patches at once when
sending a patchset, in which case we want to number the patches; on
the other hand, single patches are not usually expected to be
numbered.
In other words, the typical behavior expected from format-patch is the
one obtained by enabling autonumber, so we set it to be the default.
Users that want to disable numbering for a particular patchset can do
so with the existing -N command-line switch. Users that want to
change the default behavior can use the format.numbering config key.

When the "git status" display code was originally converted
to C, we copied the code from ls-files to discover whether a
pathname returned by read_directory was an "other", or
untracked, file.
Much later, 5698454e updated the code in ls-files to handle
some new cases caused by gitlinks. This left the code in
wt-status.c broken: it would display submodule directories
as untracked directories. Nobody noticed until now, however,
because unless status.showUntrackedFiles was set to "all",
submodule directories were not actually reported by
read_directory. So the bug was only triggered in the
presence of a submodule _and_ this config option.
This patch pulls the ls-files code into a new function,
cache_name_is_other, and uses it in both places. This should
leave the ls-files functionality the same and fix the bug
in status.

This is inspired by patches from Robin Rosenberg but takes a different
approach. This adds a "makemenu" procedure for constructing menus
that allows the menu layout to be specified in a clear fashion, and
provides one place where the alt+letter accelerators can be detected
and handled.
The alt+letter accelerator is specified by putting an ampersand (&)
before the letter for the accelerator in the menu item name. (Two
ampersands in succession produce one ampersand in the menu item as
it appears on screen.) This is handled in makemenu.
We also add an mca procedure which is like mc but also does the
ampersand translation, for use when we want to refer to a menu item
by name. The mca name and the locations where we use it were
shamelessly stolen from Robin Rosenberg's patch.
This doesn't actually add any alt+letter accelerators yet.

coming off of UPSTREAM is merged into HEAD. Initially it show up in

This adds a check saying we can keep `preserve=t` if `p=UPSTREAM`...unless this

`rebase -i -p` got its rev-list of commits to keep by --left-right and

The dropped commits were then forgotten about when it came to rewriting the
parents of their descendents, so the descendents would get cherry-picked with
their old, unwritten parents and essentially make the rebase a no-op.

POSIX doth sayeth:
"In the regular expression processing described in IEEE Std 1003.1-2001,
the <newline> is regarded as an ordinary character and both a period and
a non-matching list can match one. ... Those utilities (like grep) that
do not allow <newline>s to match are responsible for eliminating any
<newline> from strings before matching against the RE."
Thus far git has not been removing the trailing newline from strings matched
against regular expression patterns. This has the effect that (quoting
Jonathan del Strother) "... a line containing just 'FUNCNAME' (terminated by
a newline) will be matched by the pattern '^(FUNCNAME.$)' but not
'^(FUNCNAME$)'", and more simply not '^FUNCNAME$'.

The problem with this is that 'git diff' always returns non-zero if it

contain differences in order to trigger the funcname pattern codepath.

This adds an option allowing the user to select whether gitk should
look up per-file encoding settings using git check-attr or not. If
not, gitk uses the global encoding set in the git config (as reported
by git config --get gui.encoding) for all files, or if that is not
set, then the system encoding.
The option is controlled by a checkbox in the Edit->Preferences
window, and defaults to off for now because git check-attr is so
slow. When the user turns it on we discard any cached diff file
lists in treediffs, because we may not have encodings cached for
the files listed in those lists, meaning that getblobdiffline will
do it for each file, which will be really really slow.
This adjusts the limit of how many paths cache_gitattr passes to each
instance of git check-attr depending on whether we're running under
windows or not. Passing only 30 doesn't effectively amortize the
startup costs of git check-attr, but it's all we can do under windows
because of the 32k limit on arguments to a command. Under other OSes
we pass up to 1000.
Similarly we adjust how many lines gettreediffline processes depending
on whether we are doing per-file encodings so that we don't run for
too long. When we are, 500 seems to be a reasonable limit, leading
to gettreediffline taking about 60-70ms under Linux (almost all of
which is in cache_gitattr, unfortunately). This means that we can
take out the update call in cache_gitattr.
This adds a simple cache on [tclencoding]. Now that we get repeated
calls to translate the same encoding, this is useful.
This reindents the new code added in the last couple of commits to
conform to the gitk 4-space indent and makes various other improvements:
use regexp in gitattr and cache_gitattr instead of split + join + regsub,
make gui_encoding be the value from [tclencoding] to avoid having to
do [tcl_encoding $gui_encoding] in each call to get_path_encoding,
and print a warning message at startup if $gui_encoding isn't
supported by Tcl.
