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.
