As the title says, Xodus will not create and download a .csv of more than about 8000 users, a file of about 19M (18891684b actually) the file contains all 11,865 users but for some reason above 8000 no go. Which I can change with this function:
public function beforeQuery() {
$this->setProperty('limit', 0); // change to 8000
return true;
}
- PHP file/timeout/execution and memory settings are not the culprit (10 minutes and 1024M memory)
- I can download and open the file Xodus creates manually
- no (PHP) errors in webserver logs
it gets to the point in getfile.class.php:
public function outputArray(array $users, $count = false){
$this->modx->log(modX::LOG_LEVEL_ERROR,'XODUS: RUNNING outputArray');
if ($count === false) { $count = count($users);}
if($count == 0){
return '{"success":true,"message":"'.$this->modx->lexicon('xodus.export_no_users').'","object":{"total":"0"},"data":[]}';
}else{
$action_url = $this->getActionURL();
$this->modx->log(modX::LOG_LEVEL_ERROR,'XODUS: outputArray:: Got action url = ' . $action_url);
if($this->fext == 'csv'){
$this->modx->log(modX::LOG_LEVEL_ERROR,'XODUS: outputArray fext = CSV'.'{"success":true,"message":"'.count($users).' '.$this->modx->lexicon('xodus.export_users').'","object":{"file":"'.$this->timestamp.'.csv","action_url":"'.$action_url.'","total":"'.count($users).'"},"data":[]}');
return '{
"success":true,
"message":"'.count($users).' '.$this->modx->lexicon('xodus.export_users').'",
"object":{
"file":"'.$this->timestamp.'.csv",
"action_url":"'.$action_url.'",
"total":"'.count($users).'"
},
"data":[]
}';
}else{
...else....
}
}
}
So I have added some debugging, and it will output the return value (correctly) to the modx log. but the actual php force download function never fires?
public function render(){
$this->modx->log(modX::LOG_LEVEL_ERROR,'XODUS RUNNING CONTROLLER GETFILE');
$this->failure('');
$this->loadHeader = false;
$this->loadFooter = false;
$this->isFailure = false;
$this->failureMessage = '';
$this->content = '';
$this->modx->lexicon->load('xodus:default');
$core_path = dirname(dirname(__FILE__));
$file_path = $core_path.'/tmp/'.$_GET['f'];
if(file_exists($file_path)){
$filepts = explode('.',$_GET['f']);
$ext = $filepts[1];
$mimetype = '';
switch($ext){
case 'csv':
$mimetype = 'text/csv';
break;
case 'xls':
$mimetype = 'application/excel';
break;
case 'xlsx':
$mimetype = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet';
break;
}
$this->modx->log(modX::LOG_LEVEL_ERROR,'XODUS RUNNING GETFILE/SIZE = ' . filesize($file_path));
header("Content-type: application/force-download");
header('Content-Disposition: inline; filename="'.$_GET['f'].'"');
header("Content-Transfer-Encoding: Binary");
header("Content-length: ".filesize($file_path));
header('Content-Type: '.$mimetype);
header('Content-Disposition: attachment; filename="'.$_GET['f'].'"');
readfile($file_path);
unlink($file_path);
exit();
}else{
$this->modx->log(modX::LOG_LEVEL_ERROR,'XODUS: XodusGetfileManagerController::render'.print_r($scriptProperties,TRUE));
$this->modx->lexicon->load('xodus:default');
$this->content = '<html><title>'.$this->modx->lexicon('xodus').' '.$this->modx->lexicon('xodus.error').'</title><head></head><body>
<h1>'.$this->modx->lexicon('xodus').' '.$this->modx->lexicon('xodus.error').'</h1>
<p>'.$this->modx->lexicon('xodus.error_text').'. <a href="javascript:history.go(-1);">'.$this->modx->lexicon('xodus.return_link_text').'</a>.</p>
</body></html>';
return $this->content;
}
}
You will get the first log entry in that function IF I set it to export less than 8000 users.
Anyone have any idea what might be happening here?? Is modx or ExtJS somehow blocking large files or something silly? Spent an entire day on this with no progress 
HELP!
