[Exist-open] Problems with Ant 'xdb:restore' task

[Tony G. <tg...@an...>]

Using the 'xdb:backup' Ant task worked okay [1], but when I tried to use
the 'xdb:restore' task, I had multiple problems.

The 'xdb:restore' task in documented [2] as having 'dir' and 'file'
attributes, but using 'dir' produces an 'xdb:restore doesn't support the
"dir" attribute' message.

Ant really doesn't know about a 'dir' or 'file' attribute, since this is
what the 'antstructure' task dumps for 'xdb:restore' from 'develop-acd0c14':

<!ELEMENT http://exist-db.org/ant:restore (dirset)*>
<!ATTLIST http://exist-db.org/ant:restore
           id ID #IMPLIED
           configuration CDATA #IMPLIED
           uri CDATA #IMPLIED
           ssl %boolean; #IMPLIED
           user CDATA #IMPLIED
           restorepassword CDATA #IMPLIED
           initdb %boolean; #IMPLIED
           permissions CDATA #IMPLIED
           taskname CDATA #IMPLIED
           description CDATA #IMPLIED
           failonerror %boolean; #IMPLIED
           password CDATA #IMPLIED
           driver CDATA #IMPLIED>

Switching to using a <dirset>:

<target name="exist.restore">
   <xdb:restore xmlns:xdb="http://exist-db.org/ant"
	       uri="${xmldb.xmlrpc.uri}"
	       user="${xmldb.backup.user}"
	       password="${xmldb.backup.passwd}">
     <dirset dir="${xmldb.backup.dir}" />
   </xdb:restore>
</target>

produces:

exist.restore:
[xdb:restore] ERROR StatusLogger No log4j2 configuration file found. 
Using default configuration: logging only errors to the console.
[xdb:restore] Database driver registered.
[xdb:restore] Found 16677 files.
[xdb:restore] Did not found file 
.../backup/db/ahrts-data/test-local-ahrts-pdf/__contents__.xml/__contents__.xml

'backup/db/ahrts-data/test-local-ahrts-pdf/__contents__.xml'
is in the second level of '__contents__.xml' files in the backup dump.
It is:

<collection xmlns="http://exist.sourceforge.net/NS/exist" 
name="/db/ahrts-data/test-local-ahrts-pdf" owner="ahrts-data" 
group="ahrts" mode="775" created="2017-02-28T13:51:32Z" version="1">
     <acl entries="0" version="1"/>
     <subcollection name="reports" filename="reports"/>
     <subcollection name="compareOutput" filename="compareOutput"/>
</collection>

and there are no mystery, blank-named directories nor any troublesome
files or directories with '=' in their name in its directory:

total 24
drwxrwxr-x.  4 tgraham tgraham   63 Mar  2 17:24 .
drwxrwxr-x.  4 tgraham tgraham 4096 Mar  2 12:38 ..
drwxrwxr-x. 11 tgraham tgraham 4096 Mar  2 12:38 compareOutput
-rw-rw-r--.  1 tgraham tgraham  373 Mar  2 12:38 __contents__.xml
drwxrwxr-x.  2 tgraham tgraham 8192 Mar  2 12:38 reports


Trying to start the restore one level down in 'reports' finds the
right number of files but fails with a similar
'__contents__.xml/__contents__.xml' message.

Is the 'xdb:restore' task trying to treat '__contents__.xml' as a directory?
