deleted directories in 1.2.x?

[Jim Paris <ji...@jtan.com>]

I can't access deleted directories with a 1.2.0 or 1.2.1 client:

  svnadmin create testrepo
  svn mkdir file://`pwd`/testrepo/x -m 'mkdir'
  svn rm file://`pwd`/testrepo/x -m 'rm'
  svn ls -r1 file://`pwd`/testrepo
  svn ls -r1 file://`pwd`/testrepo/x

The first "svn ls" gives expected output:
  x/
while the second seems to ignore -r:
  svn: File not found: revision 2, path '/x'

It works fine with 1.1.4, even against a 1.2.0 dav_svn server, so
either something is broken, or I missed the memo about the change in
usage.

Here's the memo, from CHANGES:

     * add peg-rev syntax to co/blame/cat/ls/pget/plist/export (issue  
#1093)


And here's the section of the 1.1 book that explains peg revisions:

     http://svnbook.red-bean.com/en/1.1/ch07s03.html


Yes, the behavior changed, in the sense that we considered the older  
behavior to be a bug.  When you run 'svn ls -rX URL', it's equivalent  
to running 'svn ls -rX URL@HEAD'.  The algorithm that is followed is:

     1. go to URL@HEAD

     2. trace the object backwards to revision X

     3. return that object.

So if the directory had a different name in revision X, you'd still  
see it.

This is the general way peg-revisions work:

     svn subcommand -r X path-or-URL@PEGREV

At this time, I believe every command uses peg-revisions now, except  
for 'svn log', which is still an open bug we're working on.
