Not reproducible on GNU/Linux with Emacs 24.3 and svn 1.7.9.

Looks totally normal to me. What's supposed to be odd?

Oh, but maybe with trunk.

Thought I saw it once while testing, can't reproduce it now.

The former shows what happens with -v which is, IIUC, how the latest
vc-svn invokes it.  The latter (empty) is what happens without -v.  I
thought I was seeing vc-svn failing to parse the verbose output with the
cryptic numbers, and mistakenly concluding that the file was not registered.

I am not seeing this 100% of the time, either.

But I just saw a related thing happening:  VC-mode accepted a commit
from me where there was no actual change in the file (the commit did not
go through to the svn repo).  Here before trying vc-next-action, I
checked svn status:

[rpgoldman-3:~/org] rpg% svn status -v todo.org
             21586    21586 rpgoldman    todo.org
[rpgoldman-3:~/org] rpg% svn status todo.org
[rpgoldman-3:~/org] rpg%

I *conjecture* that the fact that there was output from svn status is
what led vc-svn to think there was a modification and present me with
the log window to make a commit.

I confess to not understanding the innards of vc-svn that well...

Again, this is totally normally svn status output that vc-svn.el has
always handled.

Thanks.  Question: isn't the stuff from my trace of vc-svn wrong?  I.e., do we agree that vc-svn is incorrectly seeing a file that's unregistered?  If that's the case, I can try to zero in on why I'm getting these bad results, and provide you some more useful feedback.

Also, is there some way I can examine the copy of vc-svn.el that I have to make sure that you and I are talking about the same thing?

Thanks for your time.

Best,
Robert

It certainly sounds like Emacs is getting the svn status of the file
wrong. This may or may not be due to a problem parsing the output of the
"svn status" external command. Eg it could be due to us not calling "svn
status"; http://debbugs.gnu.org/7850 comes to mind.

The most helpful thing is of course a recipe to reliably reproduce the problem.
Failing that, you might try edebugging vc-next-action to see why it gets
"state" wrong.

I'm using the one in the current Emacs trunk. You can use locate-library
or somesuch to find yours.

More information was requested, but no response was given within a few
months, so I'm closing this bug report.  If the problem still exists,
please reopen this bug report.
