Should `C-x v a' work for svn backend

Should `C-x v a' work for svn backend

[Leo]

Hi there,

I asked a question on the help list¹ and got no replies. I suspect it
might be a bug.

For a file that has been in svn version control, 'C-x v a' open an
empty *ChangeLog* buffer i.e., the ChangeLog buffer is not populated
with changes. Is this a missing feature or a bug?

Tested with 'emacs -Q' in GNU Emacs 22.0.93.4 (i686-pc-linux-gnu, GTK+
Version 2.10.8) of 2007-02-04.

All I can say is it works for me on recent CVS head, and recent svn
head of subversion.

I am using subversion-1.4.2-2.fc6. I have used 'Emacs -Q' to test
it. Wonder how I can get more debug info?

Find the source for the relevant function, then instrument it with C-u
M-C-x, then run it and step through it.

My limited knowledge can't find anything useful from instrumenting
'vc-update-change-log', 'vc-call-backend' and
'vc-default-update-changelog'. Help?

Gaah.  Now it's not working for me, either :-(  I don't understand why
I thought it was.

I hope you can get it back and find out the cause ;) Good luck. For
me, it never succeeds.

I wish I had read the manual before posting the OT.

,----
| `C-x v a'
|      Visit the current directory's change log file and, for registered
|      files in that directory, create new entries for versions checked
|      in since the most recent entry in the change log file.
|      (`vc-update-change-log').
| 
|      This command works with RCS or CVS only, not with any of the other
|      back ends.
