-

i sending object s3 upload , locally 'httpuploadprogress' event. notifies .progress call on function , updates record progress. works fine locally not on server. ideas appreciated. i've included 2 snippets of code. i'm using google servers, not sure if it's issue code or server settings :/

s3.uploadvideo = function (filepath, videoname, publisher_id) {  	var deferred = q.defer();  	var body = fs.createreadstream(filepath);  	var s3obj = new aws.s3({  		params: {  			bucket: transcodeconfig.nontranscodedvideobucket,  			key: publisher_id + '/' + videoname  		}  	});  	s3obj.upload({body: body}).  		on('httpuploadprogress', function (evt) {  			deferred.notify(evt);  			return  		}).  		send(function (err, data) {  			if (!err) {  				deferred.resolve(data);  				return  			} else {  				deferred.reject(err);  				return  			}  		});  	//deferred.resolve({})  	return deferred.promise;  }

aws_api.s3.uploadvideo(file.path, filename, publisher_id ).progress(function(progress){  		return models.videos.findoneandupdate({_id : trackingid},{uploadprogress: progress, file_type:fileextension},function(err,data){  			if(err){  				return next(err);  			}else{    				return data;  			}  		})  	})

PHP DOM loadHTML() method unusual warning -

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
