delete fails to delete everything it should like dangling symlinks

[tim.conway at philips.com]

Try it without "--delete-after".  I'm pretty sure that --delete-after also 
affects --force, so I think it's trying to write to the directory pointed 
to by the symlink, which doesn't exist.  I could be wrong, but that looks 
like the most likely interaction.

        Classification: 



I think someone posted this before, but I can't find it in the archives.

I am using rsync to pull down source files to be compiled.  The delete
options are used to clear out any old files left over from previous.
Normally this works.  I've run into one case where it persistently fails.

Within the directory created during compiling is a symlink to another
directory, also created during compiling (well, literally, during tar
extraction done by the script that does the compiling).  When rsync is
run to re-syncronize, which should delete all created files (including
all those extracted from the tar file), the directory that is the target
of the symlink apparently is deleted first.  Then when the symlink is
encountered, I get an error saying that readlink gets No such file or
directory.  This doesn't make sense since readlink should work on a
dangling link.

Here's a paste of manually doing the rsync within the same host
(warning, the first line is 318 characters long):

As you can see I'm using a number of options that should, according
to the man page, make sure things get deleted.  But this is not
happening.

I assume that "partial transfer (code 23)" error message is because
it did recognize that it failed to completely get things in sync.

BTW, after manually deleting the 2 symlinks, it works fine:

=============================================================================
