"svn info" to older servers returns nothing

[Zing <zi...@fastmail.fm>]

When you query older servers for info, the root of the repository returns
an empty response.  Querying subdirectories though, seems to work ok.

I have two ways to reproduce.  The easy and first way is the samba repo:

$ svn --version
svn, version 1.4.3 (r23084)
   compiled Mar 23 2007, 09:29:55

The following repository access (RA) modules are available:

* ra_dav : Module for accessing a repository via WebDAV (DeltaV) protocol.
  - handles 'http' scheme
  - handles 'https' scheme
* ra_svn : Module for accessing a repository using the svn network
protocol.
  - handles 'svn' scheme
* ra_local : Module for accessing a repository on local disk.
  - handles 'file' scheme

The second way, I setup a test repo with 1.1.4 on a older machine i had
and queried that through svn+ssh:

====== from serverold =======
$ svnadmin --version
svnadmin, version 1.1.4 (r13838)

Thanks for the report.  In a sense, this was expected behaviour: older
(pre-1.2) versions of svnserve don't provide any way to retrieve
information about the repository root.

Because of this, the current code does nothing for requests for the root
so that recursive queries (svn info -R svn://...) will continue to work.
This isn't very friendly for non-recursive queries, as you've found, and,
unfortunately, there was also a bug in that code that prevented the
recursion from working anyway.

I've changed the behaviour for non-recursive queries to return an
explicit error message, and fixed the recursive version.  The fix will
be included in Subversion 1.5.0, and I've also nominated it for the next
bugfix release in the 1.4 series.

Malcolm
