bug#2388: 23.0.90; wrong-type-argument in vc-dir

[robert]

If I run vc-dir in a svn controlled directory called 'Test Networks'
(with the internal space but not the quotes!), I get a wrong-type-argument
error, with the following traceback - 

Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  ewoc-data(nil)
  vc-dir-node-directory(nil)

when I don't have debug-on-error set to t the *vc-dir* process never
completes.

I can't reproduce this.
Can you please post step by step recipe of how you get this, starting
with emacs -Q. 
The output of 
svn -u status
in that directory might be helpful too.

I can't reproduce this either now :-(

I've done some checkins in that location and added a couple of files 
between when I reported the problem (which was very reproducible)
and now.
I will keep an eye on things and give a detailed recipe (and svn status) 
if it recurs.

I have seen this sometimes when files have needed merging/updating.  I don't
think it happened earlier because with SVN emacs didn't consult the remote
repository by default:

I still see this.  Here's a recent backtrace:

Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  ewoc-data(nil)
  (let ((data ...)) (or (vc-dir-fileinfo->directory data) 
(file-name-directory ...)))
  vc-dir-node-directory(nil)
  (let* ((rd ...) (prev-node ...) (prev-dir ...)) (unless (string-equal 
entrydir prev-dir) (ewoc-enter-before vc-ewoc node ...)))
  (cond ((string-lessp nodedir entrydir) (setq node ...)) ((string-equal 
nodedir entrydir) (let ... ...)) (t (let* ... ...) (ewoc-enter-before 
vc-ewoc node ...) (setq entries ... entry ...)))
  (let* ((entryfile ...) (entrydir ...) (nodedir ...)) (cond (... ...) 
(... ...) (t ... ... ...)))
  (while (and entry node) (let* (... ... ...) (cond ... ... ...)))
  (let ((entry ...) (node ...) (dotname ...)) (unless node 
(ewoc-enter-last vc-ewoc ...) (setq node ...)) (while (and entry node) 
(let* ... ...)) (unless (or node noinsert) (let ... ...)))
  (save-current-buffer (set-buffer buffer) (setq entries (sort entries 
...)) (let (... ... ...) (unless node ... ...) (while ... ...) (unless 
... ...)))
  (with-current-buffer buffer (setq entries (sort entries ...)) (let 
(... ... ...) (unless node ... ...) (while ... ...) (unless ... ...)))
  vc-dir-update((("." needs-update) ("mydir" needs-update) 
("pom.xml" needs-update) ("mydir1/mydir2/myfile" needs-update) 
...

which fails because node, i.e (ewoc-nth vc-ewoc 0), is nil.

Thanks for this, I've installed it and will persuade my colleagues to do 
a few checkins :-)
Not sure why svn should list '.' as needing an update.  Unfortunately my 
svn is now
up to date so I can't, currently, replicate this issue.

I would say it would be better to not install the above patch.  You can
install it whenever you hit the problem again and see if it help.
In case it doesn't saving the tree that generates the problem would help
testing a different fix.

Subject: 23.0.90; wrong-type-argument in vc-dir
Date: Thu, 19 Feb 2009 14:21:16 +0000
Message-ID: <87zlgi1p9f.fsf@tnei.co.uk>

If I run vc-dir in a svn controlled directory called 'Test Networks'
(with the internal space but not the quotes!), I get a wrong-type-argument
error, with the following traceback - 

Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  ewoc-data(nil)
  vc-dir-node-directory(nil)

when I don't have debug-on-error set to t the *vc-dir* process never
completes.

After doing "svn update -rSOME_OLDER_VERSION" it seems that "." can
appear in the "svn status" output.  So I applied this patch.

Can you please provide a recipe on how reproduce this problem starting
from 
emacs -Q
?

Can you also provide the backtrace you get when doing:
emacs -Q
M-: (setq debug-on-error t) RET
M-x load-library vc-dir.el RET

then do whatever you do to cause this problem.

Thanks.
