Switch bug
Ive found a rather anoying switch-bug that I couldnt find in the
issuetracker. It seems it deletes parts of the name of a file when
switching to a branch where the file never existed and afterwards it
seems to think that it really is a part of that branch.
Im running r3782. Attached is a script that gives this exact error
every time for me.
Is this a known bug?

aaaaaaaaaahhhhhhhhhhh.
Heh. Yup. Looks like a fairly simple brain-o, though.
If you're working on it, just assign the issue to yourself. Otherwise
I'll grab it tonight or tomorrow morning (working on some other stuff
right now).

Thanks, I'm having some local HTTP problems.
It's the same bug as the one Kent reported, but it just happens that I
used "/branch/b1" and "/trunk/foo" which happen to be the same length
(I saw the truncation and was curious :) and this happens
edit_path (c=0xbffff5c0, path=0x80b8580 "/trunk/foo")
at ../svn/subversion/libsvn_repos/delta.c:159
159 const char *editor_path = path + strlen (c->edit_base_path);
(gdb) p path
$2 = 0x80b8580 "/trunk/foo"
(gdb) p c->edit_base_path
$3 = 0x80812f0 "/branch/b1"
(gdb) n
160 if (*editor_path == '/')
(gdb) p editor_path
$4 = 0x80b858a ""
Something has obviously gone wrong, it makes no sense to mix those
paths.

No, it's really gone.

Did it delete `wc', or did it rename it to `b1'?

Yikes! Something is seriously wrong. This script
REPO=file://${PWD}/repo
svnadmin create repo
svn mkdir $REPO/trunk $REPO/branch
svn cp $REPO/trunk $REPO/branch/b1
svn mkdir $REPO/trunk/foo
svn co $REPO/trunk wc
ls wc
svn switch $REPO/branch/b1 wc
gives this error
../svn/subversion/libsvn_subr/io.c:682: (apr_err=2, src_err=0)
svn: No such file or directory
svn: svn_io_set_file_read_write: failed to set file 'wc/.svn/log' read-write
and
$ ls wc
ls: wc: No such file or directory
it's deleted my working copy.
Please raise an issue.
