-;; Some features will not work with old RCS versions. Where
-;; appropriate, VC finds out which version you have, and allows or
-;; disallows those features (stealing locks, for example, works only
-;; from 5.6.2 onwards).
-;; Even initial checkins will fail if your RCS version is so old that ci
-;; doesn't understand -t-; this has been known to happen to people running
-;; NExTSTEP 3.0.
-;;
-;; You can support the RCS -x option by customizing vc-rcs-master-templates.
-;;
-;; Proper function of the SCCS diff commands requires the shellscript vcdiff
-;; to be installed somewhere on Emacs's path for executables.
-;;
;; If your site uses the ChangeLog convention supported by Emacs, the
;; function `log-edit-comment-to-change-log' could prove a useful checkin hook,
;; although you might prefer to use C-c C-a (i.e. `log-edit-insert-changelog')
;; from the commit buffer instead or to set `log-edit-setup-invert'.
;;
-;; The vc code maintains some internal state in order to reduce expensive
-;; version-control operations to a minimum. Some names are only computed
-;; once. If you perform version control operations with the backend while
-;; vc's back is turned, or move/rename master files while vc is running,
-;; vc may get seriously confused. Don't do these things!
+;; When using SCCS, RCS, CVS: be careful not to do repo surgery, or
+;; operations like registrations and deletions and renames, outside VC
+;; while VC is running. The support for these systems was designed
+;; when disks were much slower, and the code maintains a lot of
+;; internal state in order to reduce expensive operations to a
+;; minimum. Thus, if you mess with the repo while VC's back is turned,
+;; VC may get seriously confused.
;;
-;; Developer's notes on some concurrency issues are included at the end of
-;; the file.
+;; When using Subversion or a later system, anything you do outside VC
+;; *through the VCS tools* should safely interlock with VC
+;; operations. Under these VC does little state caching, because local
+;; operations are assumed to be fast. The dividing line is
;;
;; ADDING SUPPORT FOR OTHER BACKENDS
;;
;; and then do a (funcall UPDATE-FUNCTION RESULT nil)
;; when all the results have been computed.
;; 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'.
+;; the following functions might be needed: `dir-extra-headers',
+;; `dir-printer', `extra-dir-menu' and `dir-status-files'.
;;
;; - dir-status-files (dir files default-state update-function)
;;
;; files. If not provided, the default is to consider that the files
;; are in DEFAULT-STATE.
;;
-;; - status-extra-headers (dir)
+;; - dir-extra-headers (dir)
;;
;; Return a string that will be added to the *vc-dir* buffer header.
;;
-;; - status-printer (fileinfo)
+;; - dir-printer (fileinfo)
;;
;; Pretty print the `vc-dir-fileinfo' FILEINFO.
;; If a backend needs to show more information than the default FILE
;;
;; Return non-nil if FILE is unchanged from the working revision.
;; This function should do a brief comparison of FILE's contents
-;; with those of the repository master of the working revision. If
+;; with those of the repository copy of the working revision. If
;; the backend does not have such a brief-comparison feature, the
;; default implementation of this function can be used, which
;; delegates to a full vc-BACKEND-diff. (Note that vc-BACKEND-diff
;; The default implementation deals well with all states that
;; `vc-state' can return.
;;
-;; - prettify-state-info (file)
-;;
-;; Translate the `vc-state' property of FILE into a string that can be
-;; used in a human-readable buffer. The default implementation deals well
-;; with all states that `vc-state' can return.
-;;
;; STATE-CHANGING FUNCTIONS
;;
;; * create-repo (backend)
;;
;; * checkin (files rev comment)
;;
-;; Commit changes in FILES to this backend. If REV is non-nil, that
-;; should become the new revision number (not all backends do
-;; anything with it). COMMENT is used as a check-in comment. The
-;; implementation should pass the value of vc-checkin-switches to
-;; the backend command. (Note: in older versions of VC, this
-;; command took a single file argument and not a list.)
+;; Commit changes in FILES to this backend. REV is a historical artifact
+;; and should be ignored. COMMENT is used as a check-in comment.
+;; The implementation should pass the value of vc-checkin-switches to
+;; the backend command.
;;
;; * find-revision (file rev buffer)
;;
;; arg CONTENTS-DONE is non-nil, then the contents of FILE have
;; already been reverted from a version backup, and this function
;; only needs to update the status of FILE within the backend.
+;; If FILE is in the `added' state it should be returned to the
+;; `unregistered' state.
;;
;; - rollback (files)
;;
;;
;; HISTORY FUNCTIONS
;;
-;; * print-log (files &optional buffer)
+;; * print-log (files buffer &optional shortlog start-revision limit)
+;;
+;; Insert the revision log for FILES into BUFFER.
+;; If SHORTLOG is true insert a short version of the log.
+;; If LIMIT is true insert only insert LIMIT log entries. If the
+;; backend does not support limiting the number of entries to show
+;; it should return `limit-unsupported'.
+;; If START-REVISION is given, then show the log starting from the
+;; revision. At this point START-REVISION is only required to work
+;; in conjunction with LIMIT = 1.
+;;
+;; * log-outgoing (backend remote-location)
+;;
+;; Insert in BUFFER the revision log for the changes that will be
+;; sent when performing a push operation to REMOTE-LOCATION.
;;
-;; Insert the revision log for FILES into BUFFER, or the *vc* buffer
-;; if BUFFER is nil. (Note: older versions of this function expected
-;; only a single file argument.)
+;; * log-incoming (backend remote-location)
+;;
+;; Insert in BUFFER the revision log for the changes that will be
+;; received when performing a pull operation from REMOTE-LOCATION.
;;
;; - log-view-mode ()
;;
;; Invoked from a buffer in vc-annotate-mode, return the revision
;; corresponding to the current line, or nil if there is no revision
;; corresponding to the current line.
+;; If the backend supports annotating through copies and renames,
+;; and displays a file name and a revision, then return a cons
+;; (REVISION . FILENAME).
;;
;; TAG SYSTEM
;;
;;
;; MISCELLANEOUS
;;
-;; - root (dir)
-;;
-;; Return DIR's "root" directory, that is, a parent directory of
-;; DIR for which the same backend as used for DIR applies. If no
-;; such parent exists, this function should return DIR.
-;;
;; - make-version-backups-p (file)
;;
;; Return non-nil if unmodified repository revisions of FILE should be
;; `revert' operations itself, without calling the backend system. The
;; default implementation always returns nil.
;;
+;; - root (file)
+;; Return the root of the VC controlled hierarchy for file.
+;;
;; - repository-hostname (dirname)
;;
;; Return the hostname that the backend will have to contact
;; Return the revision number that follows REV for FILE, or nil if no such
;; revision exists.
;;
+;; - log-edit-mode ()
+;;
+;; Turn on the mode used for editing the check in log. This
+;; defaults to `log-edit-mode'. If changed, it should use a mode
+;; derived from`log-edit-mode'.
+;;
;; - check-headers ()
;;
;; Return non-nil if the current buffer contains any version headers.
;; Operation called in current buffer when opening a file. This can
;; be used by the backend to setup some local variables it might need.
;;
-;; - find-file-not-found-hook ()
-;;
-;; Operation called in current buffer when opening a non-existing file.
-;; By default, this asks the user if she wants to check out the file.
-;;
;; - extra-menu ()
;;
;; Return a menu keymap, the items in the keymap will appear at the
;; to your backend and which does not map to any of the VC generic
;; concepts.
;;
-;; - extra-status-menu ()
+;; - extra-dir-menu ()
;;
;; Return a menu keymap, the items in the keymap will appear at the
;; end of the VC Status menu. The goal is to allow backends to
;; makes it possible to provide menu entries for functionality that
;; is specific to a backend and which does not map to any of the VC
;; generic concepts.
+;;
+;; - conflicted-files (dir)
+;;
+;; Return the list of files where conflict resolution is needed in
+;; the project that contains DIR.
+;; FIXME: what should it do with non-text conflicts?
;;; Todo:
;; display the branch name in the mode-line. Replace
;; vc-cvs-sticky-tag with that.
;;
-;; - C-x v b does switch to a different backend, but the mode line is not
-;; adapted accordingly. Also, it considers RCS and CVS to be the same,
-;; which is pretty confusing.
-;;
-;; - vc-create-tag and vc-retrieve-tag 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
;; the two branches. Or you locally add file FOO and then pull a
;; change that also adds a new file FOO, ...
;;
-;; - C-x v l should insert the file set in the *VC-log* buffer so that
-;; log-view can recognize it and use it for its commands.
-;;
-;; - 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.
-;;
;; - 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.
;;
;; `diff-add-change-log-entries-other-window' to create a detailed
;; skeleton for the log...
;;
-;; - The *vc-dir* buffer needs to be updated properly after VC
-;; operations on directories that change the file VC state.
-;;
;; - 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.
;; vc-dir, it is possible that these commands are called
;; for unregistered/ignored 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,
-;; vc will bombs out because it wants to see the file being in CVS.
-;; Those logs should likely use a local variable to hardware the VC they
-;; are supposed to work with.
+;; - vc-next-action needs work in order to work with multiple
+;; backends: `vc-state' returns the state for the default backend,
+;; not for the backend in the current *vc-dir* buffer.
;;
-;;;; Problems:
+;; - vc-dir-kill-dir-status-process should not be specific to dir-status,
+;; it should work for other async commands done through vc-do-command
+;; as well,
;;
-;; - the *vc-dir* buffer is not updated correctly anymore after VC
-;; operations that change the file state.
+;; - vc-dir toolbar needs more icons.
+;;
+;; - The backends should avoid using `vc-file-setprop' and `vc-file-getprop'.
