bug#8179: 24.0.50; vc thinks that SVN takes care of all my files

[Lars Magne Ingebrigtsen]

A recent(ish) change in vc has made vc-dir and friends think that all my
code is belong to svn.

(vc-svn-responsible-p "~/pgnus/lisp/")
=> "~/"

The reason is this:

(defun vc-svn-root (file)
  (vc-find-root file vc-svn-admin-directory))

(defalias 'vc-svn-responsible-p 'vc-svn-root)

and I have an ~/.svn file in ~/ (from 2008, when I probably played with
svn for five seconds).

So instead of guessing that ~/pgnus is a git thing (I mean, it has all
the git directories and stuff), instead vc guesses at svn because of
that ~/.svn directory.

I suspect that if I push SVN to the end of vc-handled-backends then
things would work again, since they're being queried in turn.

Don't know about git, but with bzr-inside-svn this only seems to affect
unregistered files.

I guess the change is becuse recent svn apparently use a single
.svn directory, rather than having one in every subdir of a checkout:

http://lists.gnu.org/archive/html/emacs-devel/2011-02/msg00357.html

Not sure what Emacs can do differently here. I think the right thing for
you to do is adjust the order of c-handled-backends to your preference,
as you say.

If root touches /.svn, then nobody on the machine can use vc for
anything by default.  That seems less than optimal.

vc should instead look at what the "closest" vc in use is.  Or the svn
checker should either be made smarter, or if that is impossible, be
moved to the end of the list by default.

For some reason, it doesn't do it that way. That does seem to make more
sense on the face of it. I imagine this must have been discussed before
somewhere... The current behaviour is documented in the manual.

Then I guess you would have the same issue with the next element in the
list.

It was somewhat discussed, but not at length.  It's mostly a feature of
the implementation, rather than by design.

That would be the case if any of the other backends are as, er,
permissive as the SVN backend is.  Which I slightly doubt.

But, really, this is a bug in the SVN detection function.  It's
perfectly legitimate to, say, check in your ~/.emacs in SVN.  If you do
that now, then the Emacs vc functionality will break completely for all
the other files you have under your home directory.

So, like I said, I think the SVN checker should be made smarter, if
possible.  I don't use SVN, so I have no idea whether that's possible or
not.

If it's not possible, it should be moved to the end of the list.

Well, take a look:

(defalias 'vc-svn-responsible-p 'vc-svn-root)

(defun vc-svn-root (file)
  (vc-find-root file vc-svn-admin-directory))


(defalias 'vc-git-responsible-p 'vc-git-root)

(defun vc-git-root (file)
  (vc-find-root file ".git"))


(defalias 'vc-hg-responsible-p 'vc-hg-root)

(defun vc-hg-root (file)
  (vc-find-root file ".hg"))


etc.

It seems that the root cause of this problem is that .svn changed from
being present in each directory to being present once per managed tree.

Maybe refining the test in vc-svn-responsible-p can solve the problem
before re-implementing the VC part that determines the backend:

 Completely untested:

(defun vc-svn-responsble-p (DIR)
   (let ((root (vc-svn-root DIR))
      ;; This assumes that vc-svn-root returns a directory name or nil
      (and root (file-exists-p (expand-file-name root "wc.db")))))

Oops.  Well, then that won't work...

Are all these VCs really that, er, difficult to determine whether they
are in effect or not?  I thought they all pretty much used a .git (or
the like) in the current directory, but that's obviously wrong...

We're only talking about unregistered files, right?
For registered files, it should get it correct every time.


For unregistered files, IIUC it effectively does:

(for backend in BACKENDS ...
  (for directory in PWD PARENTS ... )

rather than:

(for directory in PWD PARENTS ... )
  (for backend in BACKENDS ... )


I agree that the second method does seem more sensible on the face of
it, but the former is the documented way it works.

It may to some extent be an artifact of the basic design dating from the
days when you had eg a CVS directory in every directory. The "modern"
VCS have eg a single .bzr in the parent directory, not one in every
subdir as well.

Well, actually I think the doc is misleading too:

"Registering a File for Version Control"

   If the file's directory already contains files registered in a
   version control system, Emacs uses that system. If there is more than
   one system in use for a directory, Emacs uses the one that appears
   first in @code{vc-handled-backends}.


I don't think the first sentence is correct.


Anyway, I think investigating if it can be made to work the other way
would be a worthwhile experiment.

No, it seems to fail on registered files, too.

Here's my test case:

$ mkdir ~/.svn

Then I go to ~/pgnus/lisp/ChangeLog which is covered by git, and I edit
the file, and when I try to save it, I get this error message:

apply: Searching for program: no such file or directory, svn

Also, if I just say `M-x vc-dir ~/pgnus/lisp', then I get the same
error, but that's with an "unregistered file", sort of?

Yup.

I think the better approach is to use a "breadth first search".

I don't really understand that turn of phrase. Do you mean:
look for all possible backends in the PWD, if none found, then go up a
level, repeat?
