;; rather than per individual file.
;;
-;; Features in the new version:
-;; * Key commands (vc-next-action = C-x v v, vc-print-log = C-x v l, vc-revert
-;; = C-x v u, vc-rollback = C-x v c, vc-diff = C-x v =, vc-update = C-x v +)
-;; now operate on filesets rather than individual files.
-;; * The fileset for a command is either (a) all marked files in VC-dired
-;; mode, (b) the currently visited file if it's under version control,
-;; or (c) the current directory if the visited buffer is not under
-;; version control and a wildcarding-enable flag has been set.
-;;
;; If you maintain a client of the mode or customize it in your .emacs,
;; note that some backend functions which formerly took single file arguments
;; now take a list of files. These include: register, checkin, print-log,
;; This mode is fully documented in the Emacs user's manual.
;;
;; Supported version-control systems presently include CVS, RCS, GNU
-;; Arch, Subversion, Bzr, Git, Mercurial, Meta-CVS, Monotone and SCCS
+;; Arch, Subversion, Bzr, Git, Mercurial, Monotone and SCCS

;;
;; - state-heuristic (file)
;;
;; than the implementation of `state'. For a list of possible values,
;; see the doc string of `vc-state'.
;;
-;; - dir-state (dir)
-;;
-;; If provided, this function is used to find the version control
-;; state of as many files as possible in DIR, and all subdirectories
-;; of DIR, in a fast way; it is used to avoid expensive indivitual
-;; vc-state calls. The function should not return anything, but
-;; rather store the files' states into the corresponding properties.
-;; Two properties are required: `vc-backend' and `vc-state'. (Note:
-;; in older versions this method was not required to recurse into
-;; subdirectories.)
-;;
;; - dir-status (dir update-function)
;;
;; Produce RESULT: a list of lists of the form (FILE VC-STATE EXTRA)
;; To provide more backend specific functionality for `vc-dir'
;; the following functions might be needed: `status-extra-headers',
;; `status-printer', `extra-status-menu' and `dir-status-files'.
-;; This function is used by `vc-dir', a replacement for
-;; `vc-dired'. vc-dir is still under development, and is NOT
-;; feature complete. As such, the requirements for this function
-;; might change. This is a replacement for `dir-state'.
;;
;; - dir-status-files (dir files default-state update-function)
;;
;; and make sure it is displayed in the buffer's window. The default
;; implementation of this function works for RCS-style logs.
;;
-;; - wash-log (file)
-;;
-;; Remove all non-comment information from the output of print-log.
-;;
;; - comment-history (file)
;;
;; Return a string containing all log entries that were made for FILE.
;; This is used for transferring a file from one backend to another,
-;; retaining comment information. The default implementation of this
-;; function does this by calling print-log and then wash-log, and
-;; returning the resulting buffer contents as a string.
+;; retaining comment information.
;;
;; - update-changelog (files)
;;
;;; Todo:
-;; - vc-dir-kill-dir-status-process should not be specific to dir-status,
-;; it should work for other async commands as well (pull/push/...).
-;;
-;; - vc-update/vc-merge should deal with VC systems that don't
-;; update/merge on a file basis, but on a whole repository basis.
+;;;; New Primitives:
;;
;; - deal with push/pull operations.
;;
-;; - "snapshots" should be renamed to "branches", and thoroughly reworked.
+;; - add a mechanism for editing the underlying VCS's list of files
+;; to be ignored, when that's possible.
;;
-;; - when a file is in `conflict' state, turn on smerge-mode.
+;;;; Primitives that need changing:
;;
-;; - figure out what to do with conflicts that are not caused by the
-;; file contents, but by metadata or other causes. Example: File A
-;; gets renamed to B in one branch and to C in another and you merge
-;; the two branches. Or you locally add file FOO and then pull a
-;; change that also adds a new file FOO, ...
+;; - vc-update/vc-merge should deal with VC systems that don't
+;; update/merge on a file basis, but on a whole repository basis.
+;; vc-update and vc-merge assume the arguments are always files,
+;; they don't deal with directories. Make sure the *vc-dir* buffer
+;; is updated after these operations.
+;; At least bzr, git and hg should benefit from this.
+;;
+;;;; Improved branch and tag handling:
+;;
+;; - "snapshots" should be renamed to "tags", and thoroughly reworked.
;;
;; - add a generic mechanism for remembering the current branch names,
;; display the branch name in the mode-line. Replace
;; adapted accordingly. Also, it considers RCS and CVS to be the same,
;; which is pretty confusing.
;;
+;; - vc-create-snapshot and vc-retrieve-snapshot should update the
+;; buffers that might be visiting the affected files.
+;;
+;;;; Default Behavior:
+;;
+;; - do not default to RCS anymore when the current directory is not
+;; controlled by any VCS and the user does C-x v v
+;;
+;; - vc-responsible-backend should not return RCS if no backend
+;; declares itself responsible.
+;;
+;;;; Internal cleanups:
+;;
+;; - backends that care about vc-stay-local should try to take it into
+;; account for vc-dir. Is this likely to be useful???
+;;
+;; - vc-expand-dirs should take a backend parameter and only look for
+;; files managed by that backend.
+;;
+;; - Another important thing: merge all the status-like backend operations.
+;; We should remove dir-status, state, and dir-status-files, and
+;; replace them with just `status' which takes a fileset and a continuation
+;; (like dir-status) and returns a buffer in which the process(es) are run
+;; (or nil if it worked synchronously). Hopefully we can define the old
+;; 4 operations in term of this one.
+;;
+;;;; Other
+;;
+;; - when a file is in `conflict' state, turn on smerge-mode.
+;;
+;; - figure out what to do with conflicts that are not caused by the
+;; file contents, but by metadata or other causes. Example: File A
+;; gets renamed to B in one branch and to C in another and you merge
+;; the two branches. Or you locally add file FOO and then pull a
+;; change that also adds a new file FOO, ...
+;;
;; - vc-diff should be able to show the diff for all files in a
;; changeset, especially for VC systems that have per repository
;; version numbers. log-view should take advantage of this.
;;
-;; - the *VC-log* buffer needs font-locking.
-;;
;; - make it easier to write logs. Maybe C-x 4 a should add to the log
;; buffer, if one is present, instead of adding to the ChangeLog.
;;
-;; - add a mechanism for editing the underlying VCS's list of files
-;; to be ignored, when that's possible.
-;;
;; - When vc-next-action calls vc-checkin it could pre-fill the
;; *VC-log* buffer with some obvious items: the list of files that
;; were added, the list of files that were removed. If the diff is
;; `diff-add-change-log-entries-other-window' to create a detailed
;; skeleton for the log...
;;
-;; - Set `vc-dir-insert-directories' to t and check what operations
-;; and backends do not support directory arguments and fix them.
-;;
-;; - a way to do repository wide log (instead of just per
-;; file/fileset) is needed. Doing it per directory might be enough...
-;;
;; - most vc-dir backends need more work. They might need to
;; provide custom headers, use the `extra' field and deal with all
;; possible VC states.
;;
-;; - add function that calls vc-dir to `find-directory-functions'.
-;;
-;; - vc-dir needs mouse bindings.
-;;
-;; - vc-dir needs more key bindings for VC actions.
-;;
-;; - vc-dir toolbar needs more icons.
-;;
-;; - vc-dir-next-line should not print an "end of buffer" message when
-;; invoked with the cursor on the last file.
-;;
-;; - add commands to move to the prev/next directory in vc-dir.
-;;
-;; - document vc-dir in the manual.
+;; - add a function that calls vc-dir to `find-directory-functions'.
;;
;; - vc-diff, vc-annotate, etc. need to deal better with unregistered
;; files. Now that unregistered and ignored files are shown in
-;; vc-dired/vc-dir, it is possible that these commands are called
+;; vc-dir, it is possible that these commands are called
;; for unregistered/ignored files.
;;
-;; - do not default to RCS anymore when the current directory is not
-;; controlled by any VCS and the user does C-x v v
-;;
-;; - vc-create-snapshot and vc-retrieve-snapshot should update the
-;; buffers that might be visiting the affected files.
-;;
;; - Using multiple backends needs work. Given a CVS directory with some
;; files checked into git (but not all), using C-x v l to get a log file
;; from a file only present in git, and then typing RET on some log entry,
;; Those logs should likely use a local variable to hardware the VC they
;; are supposed to work with.
;;
-;; - Another important thing: merge all the status-like backend operations.
-;; We should remove dir-status, state, dir-state, and dir-status-files, and
-;; replace them with just `status' which takes a fileset and a continuation
-;; (like dir-status) and returns a buffer in which the process(es) are run
-;; (or nil if it worked synchronously). Hopefully we can define the old
-;; 4 operations in term of this one.
-;;
-;; - backends that care about vc-stay-local should try to take it into
-;; account for vc-dir. Is this likely to be useful???
-;;
-;; - vc-dir listing needs a footer generated when it's done to make it obvious
-;; that it has finished.
