Error when getting collection permissions if the collection is empty

[s...@it-innovation.soton.ac.uk]

I am using iRODS 3.0 and prods 3.0.0 beta1, and I am having a problem
getting access permissions. To get the access permissions I use the
Prods Rule class and make a rule that invokes the
“msiGetCollectionACL” micro service.

I only get an error if there is nothing in the collection. If I have
uploaded a file to the collection, the access permissions are returned
with no problems.

The error I get is the following:

iRODS Exception : Code = -15000, Cause: RODSException: [-15000
SYS_PACK_INSTRUCT_FORMAT_ERR]: RODSMessage::unpack failed.1! The
header length is unexpected: ''
, trace = #0 /opt/irodsphp/prods/src/RODSConn.class.php(1335):
RODSMessage->unpack(Resource id #34)
#1 /opt/irodsphp/prods/src/ProdsRule.class.php(55): RODSConn-
>execUserRule('getCollectionPe...', Array, Array, Array, NULL)
#2 /opt/lampp/htdocs/irods_rest_interface/irods_utils_class.php(2162):
ProdsRule->execute()

If anyone can help it would be gratefully received!

Thanks in advance

Hi Steve,

I can take a look at this.
Can you send me the piece of code where send your rule using the ProdsRule class so I can try it out here?

thanks,

Thanks very much for looking at this!

Here is the function I wrote in PHP - I suspect I am doing something
wrong but I cannot figure out what!

Thanks again

Steve

///////////////////////////////////////////////////////////////////////////
static function getObjectPermission
($account, $path) {

try {

$rule_body='getObjectPermission'.

$input_params=array(
'*objectPath'=>$path

$out_params = array('ruleExecOut');


$rule=new ProdsRule($account,$rule_body,$input_params,
$out_params);

$results = array();
$results=$rule->execute();

$output = implode (",", $results);

$result_output = print_r ($results, true);

$output2 = "Rule Exec Results: " . $result_output .

iRODSUtils::logToFile("Rule execution results = ". $output ."
another form " . $output2);

return $output;

}
catch (Exception $e) {
throw $e;

This is an update on what happened for the benefit of the list - this
turned out to be a small and subtle bug in the ERA module, and the
irods team made a fix very quickly. I put the fix into my irods
installation, and it works well and addresses the original problem I
had, so I am very pleased!

I am pretty sure the fix has been committed to the irods trunk, and I
am guessing it will be available in the next maintenance release.

I would like to publicly say thanks very much to Antoine who made the
fix, and Lisa who liaised with me initally. This kind of support is
great stuff.

Thanks again to the irods team - fantastic!
