contrib: remove git-diffall
The functionality of the "git diffall" script in contrib/ was incorporated into "git difftool" when the --dir-diff option was added in v1.7.11 (ca. June, 2012). Once difftool learned those features, the diffall script became obsolete. The only difference in behavior is that when comparing to the working tree, difftool copies any files modified by the user back to the working tree when the diff tool exits. "git diffall" required the --copy-back option to do the same. All other diffall options have the same meaning in difftool. Make life easier for people choosing a tool to use by removing the old diffall script. A pointer in the release notes should be enough to help current users migrate.

The git-diffall script provides a directory based diff mechanism
|
||||
for git.
|
||||
|
||||
To determine what diff viewer is used, the script requires either
|
||||
the 'diff.tool' or 'merge.tool' configuration option to be set.
|
||||
|
||||
This script is compatible with most common forms used to specify a
|
||||
range of revisions to diff:
|
||||
|
||||
1. git diffall: shows diff between working tree and staged changes
|
||||
2. git diffall --cached [<commit>]: shows diff between staged
|
||||
changes and HEAD (or other named commit)
|
||||
3. git diffall <commit>: shows diff between working tree and named
|
||||
commit
|
||||
4. git diffall <commit> <commit>: show diff between two named commits
|
||||
5. git diffall <commit>..<commit>: same as above
|
||||
6. git diffall <commit>...<commit>: show the changes on the branch
|
||||
containing and up to the second, starting at a common ancestor
|
||||
of both <commit>
|
||||
|
||||
Note: all forms take an optional path limiter [-- <path>*]
|
||||
|
||||
The '--extcmd=<command>' option allows the user to specify a custom
|
||||
command for viewing diffs. When given, configured defaults are
|
||||
ignored and the script runs $command $LOCAL $REMOTE. Additionally,
|
||||
$BASE is set in the environment.
|
||||
|
||||
This script is based on an example provided by Thomas Rast on the
|
||||
Git list [1]:

USAGE='[--cached] [--copy-back] [-x|--extcmd=<command>] <commit>{0,2} [-- <path>*]
|
||||
|
||||
--cached Compare to the index rather than the working tree.
|
||||
|
||||
--copy-back Copy files back to the working tree when the diff
|
||||
tool exits (in case they were modified by the
|
||||
user). This option is only valid if the diff
|
||||
compared with the working tree.
|
||||
|
||||
-x=<command>
|
||||
--extcmd=<command> Specify a custom command for viewing diffs.
|
||||
git-diffall ignores the configured defaults and
|
||||
runs $command $LOCAL $REMOTE when this option is
|
||||
specified. Additionally, $BASE is set in the
|
||||
environment.
