(vc-toggle-read-only): Explain in the doc string that users can bind
this to C-x C-q.
(vc-checkout-model): Change doc string to refer to vc-next-action,
not vc-toggle-read-only.
(vc-mode-line): Set vc-mode to nil if the file is
not version-controlled. This is necessary, e.g., if the file has
just been reverted, and thus was previously under version control
but isn't any longer.
(vc-find-file-hook): Likewise.
(vc-delete-automatic-version-backups, vc-make-version-backup): New
functions.
(vc-before-save): Use the latter.
(vc-default-make-version-backups-p): Added `-p' suffix to avoid
confusion.
* vc.el: (toplevel): Don't require `dired' at run-time.
(vc-dired-resynch-file): Remove autoload cookie.
2000-09-05 Andre Spiegel <spiegel@gnu.org>
* vc.el: Made several backend functions optional.
(vc-default-responsible-p): New function.
(vc-merge): Use RET for first version to trigger merge-news, not
prefix arg.
(vc-annotate): Handle backends that do not support annotation.
(vc-default-merge-news): Removed. The existence of a merge-news
implementation is now checked on caller sites.
* vc-hooks.el (vc-default-mode-line-string): Removed CVS special
case.
* vc-cvs.el (vc-cvs-mode-line-string): New function, handles the
special case that has been removed from the default in vc-hooks.el.
2000-09-05 Stefan Monnier <monnier@cs.yale.edu>
* vc.el (vc-log-edit): Properly handle the case where FILE is nil.
2000-09-05 Andre Spiegel <spiegel@gnu.org>

(vc-file-setprop): Use `vc-touched-properties' if bound by the new
macro `with-vc-properties' in vc.el.
(vc-file-getprop): Doc fix.
(vc-after-save): Call `vc-dired-resynch-file' only if vc is loaded.
* vc.el: Require dired-aux during compilation.
(vc-name-assoc-file): Moved to vc-sccs.el.
(with-vc-properties): New macro.
(vc-checkin, vc-checkout, vc-revert, vc-cancel-version,
vc-finish-steal): Use it.
(vc-cancel-version): Moved RCS-specific code to vc-rcs.el. The call
to the backend-specific function is now supposed to do the checkout,
too.
(vc-log-edit): Handle FILE being nil and added a FIXME for log-edit.
* vc-cvs.el (vc-cvs-checkin, vc-cvs-checkout): Don't bother to
set file properties; that gets done in the generic code now.
* vc-rcs.el (vc-rcs-uncheck): Renamed to `vc-rcs-cancel-version'.
Changed parameter list, added code from vc.el that does the
checkout, possibly with a double-take.
* vc-sccs.el (vc-sccs-name-assoc-file): Moved here from vc.el.
(vc-sccs-add-triple, vc-sccs-rename-file, vc-sccs-lookup-triple): Use
the above under the new name.
(vc-sccs-uncheck): Renamed to `vc-sccs-cancel-version'. Changed
parameter list, added checkout command.
(vc-sccs-checkin, vc-sccs-checkout): Don't bother to set file
properties; that gets done in the generic code now.
2000-09-05 Stefan Monnier <monnier@cs.yale.edu>
* vc.el: Docstring fixes (courtesy of checkdoc).
2000-09-05 Stefan Monnier <monnier@cs.yale.edu>

(vc-start-entry): Always call vc-log-edit, never vc-log-mode.
(vc-log-mode): Make it into a clean derived major mode.
(vc-log-edit): Mark buffer unmodified (as vc-log-mode did) and use

(vc-dired-mode-map): Don't set-keymap-parent yet.
(vc-dired-mode): Do set-keymap-parent here.
(vc-dired-buffers-for-dir): Nop if dired is not loaded.
(vc-default-mode-line-string): Show state
`needs-patch' as a `-' too.
(vc-after-save): Call vc-dired-resynch-file.
(vc-file-not-found-hook): Ask the user whether to
check out a non-existing file.

(vc-backend-hook-functions): Remove.
(vc-find-backend-function): Don't try to load vc-X-hooks anymore.

where vc-BACKEND-hooks.el doesn't exist.
(vc-call-backend): Cleanup.
(vc-find-backend-function): Return a cons cell if
using the default function.
(vc-call-backend): If calling the default function, pass it the
backend as first argument. Update the docstring accordingly.
(vc-default-state-heuristic, vc-default-mode-line-string): Update
for the new backend argument.
(vc-make-backend-sym): Renamed from vc-make-backend-function.
(vc-find-backend-function): Use the new name.

(vc-find-backend-function): New function.
(vc-call-backend): Use above fun and populate 'vc-functions
lazily.
(vc-backend-defines): Remove.
(vc-backend-hook-functions, vc-backend-functions)
(vc-make-backend-function, vc-call): Pass names without leading
`vc-' to vc-call-backend so we can blindly prefix them with
vc-BACKEND.
(vc-loadup): Don't load vc-X-hooks if vc-X is requested.
(vc-call-backend): Always try to load vc-X-hooks.
(vc-registered): Remove vc- in call to vc-call-backend.
(vc-default-back-end, vc-buffer-backend): Remove.
(vc-kill-buffer-hook): Remove `vc-buffer-backend' handling.
(vc-loadup): Load files quietly.
(vc-call-backend): Oops, brain fart.
(vc-locking-user): If locked by the calling user,
return that name. Redocumented.
(vc-user-login-name): Simplify the code a tiny bit.
(vc-state): Don't use 'reserved any more. Just use the same
convention as the one used for vc-<backend>-state where the
locking user (as a string) is returned.
(vc-locking-user): Update, based on the above convention. The
'vc-locking-user property has disappeared.
(vc-mode-line, vc-default-mode-line-string): Adapt to new
`vc-state'.
(vc-backend-functions): Removed vc-toggle-read-only.
(vc-toggle-read-only): Undid prev change.
(vc-master-templates): Def the obsolete var.
(vc-file-prop-obarray): Use `make-vector'.
(vc-backend-functions): Add new hookable functions
vc-toggle-read-only, vc-record-rename and vc-merge-news.
(vc-loadup): If neither backend nor default functions exist, use
the backend function rather than nil.
(vc-call-backend): If the function if not bound yet, try to load
the non-hook file to see if it provides it.
(vc-call): New macro plus use it wherever possible.
(vc-backend-subdirectory-name): Use neither `vc-default-back-end'
nor `vc-find-binary' since it's only called from
vc-mistrust-permission which is only used once the backend is
known.
(vc-checkout-model): Fix parenthesis.
(vc-recompute-state, vc-prefix-map): Move to vc.el.
(vc-backend-functions): Renamed `vc-steal' to
`vc-steal-lock'.

(vc-backend-functions): Added `vc-diff' to the list
of functions possibly implemented in a vc-BACKEND library.
(vc-checkout-required): Bug fixed that caused an error to be
signaled during `vc-after-save'.
(vc-backend-hook-functions): `vc-checkout-required'
updated to `vc-uses-locking'.
(vc-checkout-required): Call to backend function
`vc-checkout-required' updated to `vc-uses-locking' instead.
(vc-parse-buffer): Bug found and fixed.
(vc-backend-functions): `vc-annotate-command',
`vc-annotate-difference' added to supported backend functions.
vc-state-heuristic added to
vc-backend-hook-functions.
Implemented new state model.
(vc-state, vc-state-heuristic, vc-default-state-heuristic): New
functions.
(vc-locking-user): Simplified. Now only needed if the file is
locked by somebody else.
(vc-lock-from-permissions): Removed. Functionality is in
vc-sccs-hooks.el and vc-rcs-hooks.el now.
(vc-mode-line-string): New name for former vc-status. Adapted.
(vc-mode-line): Adapted to use the above. Removed optional
parameter.
(vc-master-templates): Is really obsolete.
Commented out the definition for now. What is the right procedure
to get rid of it?
(vc-registered, vc-backend, vc-buffer-backend, vc-name): Largely
rewritten.
(vc-default-registered): Removed.
(vc-check-master-templates): New function; does mostly what the
above did before.
(vc-locking-user): Don't rely on the backend to set the property.
(vc-latest-version, vc-your-latest-version): Removed.
(vc-backend-hook-functions): Removed them from this list, too.
(vc-fetch-properties): Removed.
(vc-workfile-version): Doc fix.
(vc-consult-rcs-headers):
Moved into vc-rcs-hooks.el, under the name
vc-rcs-consult-headers.
(vc-master-locks, vc-master-locking-user):
Moved into both
vc-rcs-hooks.el and vc-sccs-hooks.el. These properties and access
functions are implementation details of those two backends.
(vc-parse-locks, vc-fetch-master-properties): Split
into back-end specific parts and removed. Callers not updated
yet; because I guess these callers will disappear into back-end
specific files anyway.
(vc-checkout-model): Renamed to vc-uses-locking.
Store yes/no in the property, and return t/nil. Updated all
callers.
(vc-checkout-model): Punt to backends.
(vc-default-locking-user): New function.
(vc-locking-user, vc-workfile-version): Punt to backends.
(vc-rcsdiff-knows-brief, vc-rcs-lock-from-diff)
(vc-master-workfile-version): Moved from vc-hooks.
(vc-lock-file): Moved to vc-sccs-hooks and renamed.
(vc-handle-cvs, vc-cvs-parse-status, vc-cvs-status):
Moved to vc-cvs-hooks.
Add doc strings in various places. Simplify the
minor mode setup.

(vc-parse-buffer, vc-insert-file, vc-default-registered): Minor
simplification.
(vc-backend-hook-functions, vc-backend-functions):
New variable.
(vc-make-backend-function, vc-loadup, vc-call-backend)
(vc-backend-defines): New functions.
Various doc fixes.
(vc-default-back-end, vc-follow-symlinks): Custom fix.
(vc-match-substring): Function removed. Callers changed to use
match-string.
(vc-lock-file, vc-consult-rcs-headers, vc-kill-buffer-hook):
Simplify.
vc-registered has been renamed
vc-default-registered. Some functions have been moved to the
backend specific files. they all support the
vc-BACKEND-registered functions.
This is 1998-11-11T18:47:32Z!kwzh@gnu.org from the emacs sources
(vc-fetch-master-properties): Moved cvs status retrieval to the above.
(vc-backend): If a file is not registered, remember that by setting
the property to `none'.
(vc-name): Use the mechanism of vc-backend to compute the value.
(vc-after-save): Don't access vc-backend property directly.
transitions.
(vc-find-cvs-master): Convert UTC string to encoded time and compare
the results to the file attributes, rather than attempting to convert
file attributes to UTC string (which wasn't reliable).
(vc-find-cvs-master): Use it to compare mtime and checkout time.
(vc-locking-user): CVS case: *only* use checkout time.
(vc-find-cvs-master): Don't attempt to find the RCS master file.
Throw the full name of CVS/Entries.
(vc-name): Doc change (special CVS case).
(vc-after-save): Handle the case when a file is saved in the very
second in which it was checked out.
(vc-fetch-master-properties): CVS case: Use it.
(vc-lock-from-permissions, vc-file-owner, vc-rcs-lock-from-diff):
New functions.
(vc-locking-user): Largely rewritten. Uses the above, handles RCS
non-strict locking. Under CVS in CVSREAD-mode, learn the locking state
from the permissions.
(vc-find-cvs-master): Use vc-insert-file, rather than
find-file-noselect. Greatly speeds up things.
(vc-consult-rcs-headers): Bug fix, return status in all cases.
CVS case: new state `locally-added'.
(vc-locking-user): Under RCS with non-strict locking, don't trust
the file permissions. CVS case: change which states count as
"locked".
(vc-consult-rcs-headers): Streamlined. Don't set vc-locking-user if
this is called under CVS. Under RCS, use a heuristic to find the
value of vc-checkout-model without examining the master file.
(vc-parse-locks): Set vc-checkout-model.
(vc-status): Comment change.
(vc-after-save-hook, vc-after-save): The former renamed to the
latter. Now unconditionally called by `basic-save-buffer', determines
whether the buffer should be "locked" or not.
(vc-mode-line): No longer use dynamic after-save-hook. Changed
references to `automatic' into `implicit'.
(vc-checkout-model): Values are now `manual' and `implicit'. Derive
the property on a per-file basis, supporting all possible modes.
(vc-locking-user): Count cvs status `unresolved-conflict' as "locked".
(vc-checkout-model): New property and access function (still simplistic).
(vc-after-save-hook): New function.
(vc-mode-line): When the file is locked by somebody else, make the
buffer read-only. (Formerly this was only done for root.) Don't
write-protect the buffer if the file is unlocked. Instead, install
vc-after-save-hook, which "locks" the file when modifications are
saved.
VC-Log buffer. Better mode line text for initial comments.
Streamlined the function.
(vc-locking-user): Consider a cvs file "locked"
if its status is either 'locally-modified or 'needs-merge.
(vc-workfile-version): Catch 'found when calling vc-find-cvs-master.
(vc-fetch-master-properties): Handle cvs status "Needs Checkout".
This is intended for future use.
(vc-fetch-master-properties): Shrink the window
that displays the error message.
(vc-fetch-master-properties, vc-fetch-properties): Don't erase the
buffer because that is now done in vc-insert-file.
(vc-fetch-properties): Kill the *vc-info* buffer when done.
don't look for vc-latest-version and vc-your-latest-version here.
Read only through ^locks unless we need to find the tip of a branch.
(vc-consult-rcs-headers): Use non-regexp search to find the headers.
(vc-latest-version, vc-your-latest-version): Use vc-fetch-properties.
(vc-fetch-properties): New function.
master file directly, instead of using rlog. The properties
retrieved from the master file are kept separately. The two
main properties, `vc-workfile-version' and `vc-locking-user',
are inferred from those master file properties if the
information cannot be found elsehow. All properties are
consistently cached now.
(vc-master-info, vc-log-info, vc-fetch-properties): functions
removed. Their job is now done by `vc-fetch-master-properties'
and `vc-insert-file'.
(vc-fetch-master-properties): new function, replaces
vc-fetch-properties. Retrieves all the properties that can be
found in the master file, for all three backends (calls
`cvs status' in the CVS case).
(vc-insert-file): new function. Inserts an arbitrary file
into the current buffer, optionally chunkwise, until a certain
regexp shows up.
(vc-parse-locks): new function. Translates SCCS or RCS lock
lists, as found in the master files, into lisp lists. Sets
the new property `vc-master-locks'.
(vc-locked-version): property removed. Was unnecessary, and
only referenced in vc-hooks.el.
(vc-head-version, vc-default-branch, vc-master-locks):
new properties.
(vc-top-version): new name for the old property
`vc-branch-version'. ("top-version" is better because it
might also be the RCS "head" if there is no default branch.)
(vc-master-locking-user): replaces `vc-true-locking-user'.
Scans the new `vc-master-locks' property, yielding the master
file's idea of who is locking the current workfile version.
(vc-locking-user): slightly changed to use the new properties.
Changed the actual property value for an unlocked file to
'none. This is to distinguish it from an unknown locking
state, which is represented by nil. The function vc-locking-user
returns nil if the property is 'none, to make it compatible with
the rest of VC.
(vc-consult-rcs-headers, vc-master-locking-user): adpated to
the new 'none-value of vc-locking-user.
(vc-consult-rcs-headers): fixed bug that prevented
(not vc-consult-headers) from working
(vc-file-not-found-hook): set the default-directory of the new
buffer before check-out. (Otherwise, setting vc-keep-workfiles
to nil doesn't work.)
(vc-occurences, vc-branch-p): functions removed (no longer needed)
Reordered some defuns so they are grouped in a logical way.
(vc-mistrust-permissions, vc-keep-workfiles): Customization
variables, moved here from vc.el.
(vc-trunk-p, vc-minor-revision, vc-branch-part): Moved to vc.el.
(vc-backend): Renamed from vc-backend-deduce. Callers changed.
(vc-match-substring, vc-lock-file, vc-parse-buffer, vc-master-info):
(vc-log-info, vc-consult-rcs-headers, vc-fetch-properties):
(vc-backend-subdirectory-name, vc-locking-user, vc-true-locking-user):
(vc-latest-version, vc-your-latest-version, vc-branch-version):
(vc-workfile-version): Functions moved here from vc.el.
(vc-log-info): Log program is no longer called through vc-do-command,
to avoid including the lengthy vc-do-command here. It is done
directly through call-process now. Removed obsolete parameter LAST.
(vc-status): Replaced by the much simpler version that gets the
information from the file properties. Removed the obsolete
parameter vc-type.
(vc-parse-buffer): changed format of PATTERNS. Each pattern is now a
list of 2 to 3 elements, the first being the pattern, the remaining
ones the numbers of subexpressions to refer to.
(vc-cvs-status): New per-file property, only used in the CVS case.
(vc-cvs-status): New function.
(vc-log-info): Adapted to new version of vc-parse-buffer
(vc-fetch-properties): Adapted to new version of vc-parse-buffer.
Better search regexp for CVS latest version.
(vc-log-info): Search for branch version only in the RCS case,
since this doesn't make sense for SCCS or CVS.
(vc-fetch-properties): CVS case: set vc-cvs-status.
(vc-locking-user): CVS case: use vc-cvs-status to determine if
the file is up-to-date, thus avoiding an expensive call to
vc-workfile-unchanged-p.
(vc-mode-line): Re-activated the code that makes the buffer read-only
if the work file is unchanged. But the status of the work file
is now determined by looking at the already-computed mode string.
Also new variable, local in all buffers.
(vc-kill-buffer-hook): Kill local vc-buffer-backend.
(vc-kill-buffer-hook): Don't put it on kill-buffer-hook.
(vc-file-clearprops): Function moved here.
(vc-workfile-version): Function moved here.
(vc-mode-line): Don't call vc-locking-user.
Add branch support for RCS; treat CVS more like RCS and SCCS.
(vc-occurences, vc-trunk-p, vc-branch-p, vc-minor-revision)
(vc-branch-part): new functions that operate on RCS revision numbers.
(vc-status): Use the new property vc-workfile-version
and vc-locking-user (see vc.el). Display "locking state" for CVS.
(vc-find-cvs-master): Search for file name case-sensitively, store
version number into the new property vc-workfile-version.
(vc-find-file-hook): kill any remaining properties. Like this,
when re-finding a file (for example because it has changed on disk),
the version control state gets re-computed.
(vc-mode-line): CVS case: make the buffer read-only if the file
is unmodified.
(vc-kill-buffer-hook): Clear file's vc props when buffer is killed.
(vc-find-cvs-master): New function.
(vc-master-templates): Add vc-find-cvs-master.
(vc-registered): Allow vc-master-templates to contain atoms, and
call them with dirname and basename as arguments.
(vc-mode-line): Use equal, not string-equal, to
compare the result of vc-locking-user.
(vc-status): Use vc-path when calling prs.
(vc-status): New arg vc-type.
(vc-file-not-found-hook): Use save-excursion.
(vc-status): Renamed from vc-rcs-status. Handle SCCS.
(vc-display-status): Renamed from vc-rcs-status.
(vc-mode-line): Call vc-status for SCCS files too.
(vc-name, vc-backend-deduce): Set both vc-name and vc-backend
properties, to avoid calling vc-registered unnecessarily when
the other property is needed.
(vc-rcs-status): Yield only status of locks; do not try to yield " REV"
if there are no locks, since this cannot be done easily if there are
branches. Use vc-name instead of duplicating its function incorrectly.
Fix off-by-one bug when inserting master header pieces. Read headers
8192 bytes at a time instead of 100. Don't bother to expand-file-name.
(vc-rcs-glean-field): Removed.
