I was on the road, with only spotty access to email, all last week.
During this time there was, apparently, a lot of VC-related activity 
including discussion of a new interface that has been partially 
implemented, and several patches flying back and forth. 

I have time to work on VC and consider myself responsible for it
(especially since the new-VC rewrite).  But I am unclear on what needs
to be done with VC at this point.

Would those of you who have been hacking please summarize the design
and coding issues as you see them?  From that I will try to put together
some sort of roadmap and get a start on executing it.

There are a few bug reports, some with patches, that were never looked
at.  Reviewing those would be a good start.

This is my list for vc-status.  It is roughly in order from core
pieces to UI.

* Make a new 'update' back end function to update the tree.

* Make dir-status back end function update the vc-status buffer
  asynchronously.  This means using a process filter.

* Don't clear vc-status buffer when updating.  This means figuring out
  how to insert new items into the ewoc at the right point.

* Figure out what to do about 'conflict' -- seems like it should be a
  state, but none of VC seems prepared for that.  There was some
  discussion about this.

* Add more bindings.  At least 'commit' and 'update' are needed.
  In general, copy stuff from pcl-cvs or psvn.
  We also need a menu and maybe a toolbar.

* Implement dir-status and update functions for all back ends.

* A few rough edges... allow multiple vc-status buffers.  Decide
  general approach to running the sub-process (what buffer to use,
  etc; there was some traffic about this).  Decide how to allow
  interrupting the process.  Update the vc-status buffer when a
  modification is made to a buffer visiting one of the listed files.

* Whatever else that pcl-cvs does that is cool that vc-status should
  have.

FWIW I am hardly working on this.  I send a patch as the mood strikes.
So, don't worry too much about duplicating effort :).  Dan, I think,
is leading it.

I probably forgot something.

According to the psvn maintainer it is due to sorting the entries
after svn exits.

Anyway the experiment is pretty easy.  I will try to remember to do it.

This is not the same if a marked file changes from modified to unmodified.
In this case it will disappear from the listing.

IMO it is nicer UI for the entries to persist a bit.

Pointers? 
I only remember one bug:

Most code discussion has been about vc-status.

By this time I think that we can declare the vc-status experiment a
success. It is in decent shape and the code is still very simple and
understandable.  Do you agree?

I added a TODO list to vc.el, and I have some additions to that list in
my uncommitted tree.  IMO this list can be used as a start for a
roadmap. Here's the list:

;; - Make vc-checkin avoid reverting the buffer if has not changed
;;   after the checkin.  Comparing (md5 BUFFER) to (md5 FILE) should
;;   be enough.
;;
;; - 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-register should register multiple files at a time. The
;;  `register' backend function already supports that.
;;
;; - the backend sometimes knows when a file it opens has been marked
;;   by the VCS as having a "conflict". Find a way to pass this info -
;;   to VC so that it can turn on smerge-mode when opening such a
;;   file.
;;
;; - 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 there's one instead of the ChangeLog.
;;
;; - make vc-state for all backends return 'unregistered instead of
;;   nil for unregistered files, then update vc-next-action.
;;
;; - add a generic mechanism for remembering the current branch names,
;;   display the branch name in the mode-line. Replace
;;   vc-cvs-sticky-tag with that.
;; 
;; - vc-register should register a fileset at a time. The backends
;;   already support this, only the front-end needs to be change to
;;   handle multiple files at a time.
;;
;; - deal with push/pull operations.
;;
;; - decide if vc-status should replace vc-dired.
;;
;; - vc-status needs a menu, mouse bindings and some color bling.
;;
;; - "snapshots" should be renamed to "branches", and thoroughly
;;   reworked.
;;

Now, onto Tom's list:

I am not yet convinced that we should do this. The discussion on this
was started by your observation that PCL-CVS and psvn "pause" when
updating the display. It would be good to actually investigate and see
what the cause of the "pause" is, and make sure that it can be fixed by
going asynchronous. 

Anyway, updating asynchronously is not a big change from the vc.el point
of view. Just a few lines need to change. The backends would have to
change more stuff to use process filters. But that should not be too
hard either once there a working model.

We don't need to do this right away an easy stopgap: we can keep a list
of selected items and select them at the time they are inserted.

Agreed.

One such cool thing is: when a files is modified and its directory is
shown in a vc-status buffer, add it there.

Hehe, hardly. I don't really have time to lead this properly, so the job
is up for grabs :-)

That's pretty much how PCL-CVS used to work, and indeed it sucked.
Now PCL-CVS tries to never remove entries unless the user asks for it
explicitly (typically with the `x' key which says "remove up-to-date
entries").
Actually, I find that the *cvs* buffer should also always list files
that are open in an Emacs buffer.  E.g. I use a find-file-hook to
automatically add files I visit to the *cvs* buffer(s).

Does this still happen? This might have been due to bugs due to the
introduction of the ignored and unregistered states.

This should have been fixed by a different patch.

Don't know about this one. If you think is correct and you tested it, I
can check it in.  Although I hope you get commit access soon.

Sure it's not.  The point here is just to move it from the
"experimental, can be deleted anytime" state to "work in progress, this
is the future" so that more people can work on this.

OK. Would this need a change in the interface to the backend?

The problem here is indeed in vc-diff-sentinel. It calls 
(shrink-window-if-larger-than-buffer)
which does this:
  (when (null window)
    (setq window (selected-window)))

So it will look at (selected-window), so it will shrink the wrong
window... 
Not sure what the best solution is here.

  > vc-dired refresh

This is for vc-dired. Needs to be looked checked if it still happens
when vc-dired is replaced with vc-status.

i just installed a fix.

btw, in the cvs log, i used the format:

  ONE-LINE-DESCRIPTION.
  
  (FUNC): CHANGE.
  (OTHER-FUNC): CHANGE.
  
as opposed to the format w/o `ONE-LINE-DESCRIPTION.\n\n'
(which is what went into ChangeLog).  any objections?

   strange byte compiler behavior
   http://lists.gnu.org/archive/html/emacs-devel/2007-12/msg01356.html

IIRC someone wanted to investigate the byte compiler's diagnostics, thus
delaying resolution of the next bug.  However, that doesn't seem as
important to me as fixing the bug, so...

Plese fix your fix so that it doesn't use just (get-buffer-window buf)
but (get-buffer-window buf t) like in the fix I installed minutes before
on the 22 branch.

The third argument to get-buffer-window really should not be optional,
to force people to think a bit more about the multi-frame case, which is
all too often ignored.

I don't think so.  Maybe it would be nice to have a function that is

couple times.

That is a good point, but I think such a change would break lots of

Yes, I didn't mean to change it, I meant it as "the way things should be

with the above changes, vc-workfile-unchanged-p will return nil when  
the test for the first if is false (and checkout-time ...).  This vc  
will consider the file changed each time the checkout-time is not  
known.  How about:

That seems to be necessary only when doing partial updates.  Now the
update is complete when vc-update-vc-status-buffer gets called.

But maybe first we should wait for ESR to post his plan/roadmap before
doing any further changes. Hopefully this will happen soon ...

Any news about this?

IMO the most pressing need right now is to move vc-status from it's
state of limbo.

Given how simple the vc-status code is, how easy it is to extend, and
how long it took for fundamental problems in vc-dired to be fixed, it's
quite easy to conclude that vc-status is the best way to go forward.

Sorry, I've been heads-down on another project.  Actually it's Battle For 
Wesnoth, the one I've held up as a tool-use model here.  We're heading
towards a major stable 1.4 release and, as I'm one of the core devs, this 
involves a huge amount of work.

I'll get back to working on VC probably around the first week of
March, possibly earlier.  In the meantime, anybody who wants to take the
initiative on moving VC to use vc-status sooner has my approval and 
encouragement to do it.

   AFAIK no.

I have just added vc-dir-status for Git.  Sigh, moments after
the C-c C-c, i see new func vc-git--ls-files-state, which
probably could have been useful.  However, before doing any
more munging, it would be nice for us to figure out what is
vc-dir-status philosophy and design, and write that down in a
vc.el comment so that backend support can derive guidance and
check for conformance.  Labeling everything EXPERIMENTAL is
lame; one such warning in vc.el should suffice.

Personally, i don't think vc-directory for Git is that bad
(w/ some tweaking)[0].  I *like* the "v" prefix, non-flat
(visible) directory hierarchy, and support for RCS and CVS.
I get the feeling that vc-dir-status is simply ewoc wanking.
Perhaps a nice comment in vc.el would dispell that, hint hint.

Is there a way to force vc-directory to not show "(ignored)" entries?
Actually, it seems kind of stupid that it shows them by default (if
they're marked "ignore", why are you showing them to me?).

Do you have any junk files around in that directory, which match your
git ignore specs?

If I just do M-x vc-directory RET in a git directory, I see stuff like:

  -rw-rw---- (ignored)  2007-07-31 15:16 +foo
  -rw-rw---- (ignored)  2008-01-10 15:07 ,1
  -rw-rw---- (ignored)  2008-01-10 15:19 ,2
  -rw-rw---- (ignored)  2008-01-10 15:32 ,3
  ... etc ...

[Some of the ignored stuff should be matched by my "user" gitignore file
(git config core.excludesfile), and some of it should be matched by the
.gitignore file in that directory.]

   Do you have any junk files around in that directory, which match
   your git ignore specs?

Yes.  For example, in .gitignore first line is "*.texi" and in the
directory there are 89 .texi files.  I don't have a "user" gitignore
file, however.  FWIW, i use git 1.5.3.5 (plus ttn mods).

Sorry, but this sounds too much like a rant for missing the obvious:
the implementation for `vc-git-dir-status' should be modeled after
the thing it tries to replace: `vc-git-dir-state'.

vc-status code was added as a PROOF OF CONCEPT that it's easy to replace
vc-dired with something that is simpler, it has more features
(asynchronous), it can be easily extended and it does not take 10 years
to find fundamental bugs.  
As long as it stayed in experimental state (and that was until
yesterday) it made more sense to spend time writing proof of concept
code, and there was little point to spend time writing ISO9000 type
documents describing it.
On top of that, everything was discussed at length on the list.

You mean "vc-git-hacking"? That link does not work.
It would be more productive to add that code to vc-git, or post it here.

Feel free to add them.

This bad attitude and adding this type of rants to vc-git.el:

;;; vc-dir-status support (EXPERIMENTAL)
;;; If vc-directory (which is not half bad under Git, w/ some tweaking)
;;; is to go away, vc-dir-status must at least support the same
;;; operations.  At the moment, vc-dir-status design is still fluid (a
;;; kind way to say half-baked, undocumented, and spottily-supported),
;;; so the following should be considered likewise ripe for sudden
;;; unannounced change.  YHBW, HAND.  --ttn

are totally counter-productive and seem to be designed just to aggravate
people instead of focusing on improving ANYTHING.

All i ask for is some comments in the source code, as a courtesy
to anyone who has not followed the discussion.  I think a brief
summary (no need for a lot of spew) of the conclusions reached,
together w/ the code, would "prove" the concept better.

   You mean "vc-git-hacking"? That link does not work.

I see this:
 $ cd /tmp
 $ git clone http://www.gnuvola.org/wip/vc-git-hacking.git
 Initialized empty Git repository in /tmp/vc-git-hacking/.git/

What do you see?

   This bad attitude and adding this type of rants to vc-git.el: [...]
   are totally counter-productive and seem to be designed just to
   aggravate people instead of focusing on improving ANYTHING.

Anger is a gift, supposedly, but i can see that aggravation is
just aggravation.  To get to actual anger, you have to read the
above comment as standing in for the lack of comments in vc.el.
They are two sides of the same coin: anger from fear, fear from
ignorance, ignorance from limited attention budget; we are like
brothers now!  What is it that we fear, together?

No worries, i understand joy of implementation can occlude sense
of responsibility.  Why leave a crumb for other programmers when
the bread mashes nicely in one's maw?

I think the bad attitude to be weeded out is the one that results
in thought codified but not fully transparent.

I added a description.

It works now, it used to give an error saying something about needing to
run update-server-info.

Now, this is a transition from obnoxious to unreasonable.  I explained
pretty clearly that the code was under development and used a demo to
ESR how things could work.  I wanted to waste no effort on stuff the
might be just thrown way.  This was done in public instead of doing it
in private email.  The amount of code is quite small and was discussed
on the list.
This silliness has gone beyond reasonable limits, so I am done
discussing it.  
If you are interested in improving the code, you are welcome to go ahead
and do it, but just talking about absolutely nothing important is just a
waste of time.

   [Some of the ignored stuff should be matched by my "user"
   gitignore file (git config core.excludesfile), and some of it
   should be matched by the .gitignore file in that directory.]

I have pushed a fix for this in
http://www.gnuvola.org/wip/  (vc-status-hacking)

You might need vc-git-hacking, too, i'm not sure; they have
only been tested together, w/ the ~/.emacs frag:

  (let ((default-directory "~/build/vc-status-hacking/"))
    (load-file "loadup.el"))
  (setq vc-dired-never-show-ignored t)
  (load "~/build/vc-git-hacking/vc-git-hacking.el")

Munge hardcoded paths to taste, of course...
