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.
