svn:externals to older revision of deleted path

["Alves, Pedro Maia (NSN - PT/Amadora)" <pe...@nsn.com>]

Hi,
 
I have two repositories and in one I have an svn:externals property to
the other with fixed revision.
For example I have in on directory of REP1 an svn:externals property, to
get a directory from REP2, similar to:
 
-r49 http://REP2/trunk/xpto xpto
 
Now, I decide that I don't want anymore to have the xpto directory and
in revision 76 of REP2 I deleted the directory.
If I don't change the svn:externals property on REP1 I should be able to
get revision 49 of the xpto directory when I'm checking out the
directory from REP1 because on revision 49 the directory still existed
on REP2.
 
However if I try to check out REP1 I'm getting the following message:
 
'/svn/REP2/!svn/bc/76/trunk/xpto' path not found
 
It seams that it is looking for the directory first on the HEAD revision
(76) which doesn't make sense because I want revision 49.
 
I'm using 1.5.5-SlikSvn-tag-1.5.5@34877-WIN32.
 
Do you think this is a bug on svn?
 
Thank you and best regards,
 
Pedro Maia Alves

That is correct.

No, it works as intended.

You need to understand the difference between peg and operative  
revisions.

http://svnbook.red-bean.com/en/1.5/svn.advanced.pegrevs.html

You'll see that externals definitions now support both peg and  
operative revisions.

http://subversion.tigris.org/svn_1.5_releasenotes.html#externals

So the correct externals definition now would be

-r49 http://REP2/trunk/xpto@49 xpto

That would definitely work, or possibly it can be shortened to just  
specify the peg revision.

http://REP2/trunk/xpto@49 xpto

But I'm never sure if the operative revision defaults to the peg  
revision or to HEAD.
