| Receive session enabled messages Azure Bus Service Posted: 26 Jun 2021 09:23 AM PDT I currently have a standard process that sends messages to a queue using: var queueHandler = new QueueHandler(new QueueManager(messageRequest.queueName)); queueHandler.AddMessage(jsonContent);
Everything is fine, receiving messages on a function Bus Service aware: public static async void Run([ServiceBusTrigger("MyQueueName")] string myQueueItem, ILogger log)
So it works auto on the server. Now I need to use session enabled queues, which can't be set up like this. How do you set up the Functions to be automatically triggered based on those messages? Do I have to periodically read the sessions? Do I have to schedule a function? The documentation says nothing about this, they just use console applications, which won't work on my scenario, I need them to be automatically processed, based on create or every X time. What are the best practises for this? Thank you.  |

| Timing how frequently a function is called ignoring the time spent in the function itself in multiprocessing Posted: 26 Jun 2021 09:23 AM PDT The problem I have been stuck on is more towards logical thinking. Consider a resource R. R can be produced programatically and has three characteristics: - Each unit of R takes an almost constant time T to produce
- Each unit of R costs money to produce
- Each unit of R becomes obselete if it is not used within 60s of production
Moreover, the workers that require R have two caveats as well: - They need R to carry out their tasks. Hence, they block until they recieve a unit.
- There can be multiple worker processes running concurrently.
Keeping these in mind, since production costs money, and there is an expiry time limit, my goal is to produce R in a quanitiy large enough so that the workers block for the least amount of time and small enough so the units don't expire. To manage this, I have the class RManager below: from multiprocessing import Queue, Manager, Lock, managers import logging from functools import wraps from inspect import signature import queue as Q class RManager: minimum = 1 T = 20 # Amount of time required to produce expiryT = 60 # Amount of time after which, if unused, the unit of R becomes useless def __init__(self, q): m = Manager() # The Queue that in which we send requests to produce R self.requestQueue = q # The Queue in which we receive units of R after production self.responseQueue = m.Queue() # To handle concurrent accesss self.instanceLock = Lock() # These will be defined as they are used self.processing = 0 self.total = 0 self.RequestRate = {'rate': 0.0, 'num': 0, 'total_time': 0.0, 'last_request': time.time()} def get_request(self, timeout=60): """ This function is called by workers to request a unit of R""" # We update information about how frequently this method is called in the atrribute 'RequestRate', to gauge how frequently # do the worker(s) require resource R. Basically, we add the time difference between successive calls of this method # and divide that by the number of times this method is called. This gives us the rate of this method being called. with self.instanceLock: self.RequestRate['total_time'] += time.time() - self.RequestRate['last_request'] self.RequestRate['num'] += 1 self.RequestRate['last_request'] = time.time() self.RequestRate['rate'] = self.RequestRate['total_time'] / self.RequestRate['num'] try: R = self.responseQueue.get(timeout=timeout) # We got a unit of R, so we increment the total units recieved. with self.instanceLock: self.total += 1 return R except Q.Empty: return 'timeout' def send_request(self): """ This function is called by workers periodically. It decides how many requests to send to produce resource R based on usage data """ instructions = {'improtant': 'things', 'response': self.responseQueue, 'time': time.time()} # Instructions on how to produce R to_send = RManager.minimum # Number of units of R that would be requested, initialized as minimum allowed if self.total >= 3: # We only go here if have enough collected data about usage with self.instanceLock: # In this we check status of resource availability after time RManager.T to see how many requests we should send # Currently, self.processing number of units of R are being produced. These all units will be definitly finish # production by time RManager.T to_add = self.processing # During the production time RManager.T, there will be units used up as well. This is given by below to_subtract = RManager.T // self.RequestRate['rate'] # We then find the amount of units finally available after time RManager.T keeping in mind there may already be some # present in the responseQueue future_available = self.responseQueue.qsize() + to_add - to_subtract # Now we calculate the amount of time these units will require to be used up total_time = future_available * self.RequestRate['rate'] # Now if the time to use them all up is below expiry time, we can request more units to be added. To do this, we # calculate the optimal amount of units that will need to be produced to keep up with the rate of request. # The number of units needed is then the difference between this value and the units that would actually be available # after RManager.T seconds. if total_time < RManager.expiryT - 15: optimal_future_available = (RManager.expiryT - 15) // self.RequestRate['rate'] to_send = min(optimal_future_available - future_available) # Send requests to produce R for _ in range(to_send): self.requestQueue.put(instructions) # Increment the counter which tells how many units are going to be ready soon with self.instanceLock: self.processing += to_send @staticmethod def requestsManager(requestQueue): """ This staticmethod is called in a separate process from the worker processes which produces R upon request. All requests for units of R are answered within RManager.T time regardless of quantity because production happens simultaneously.""" reqs = [] # Get all requests from queue and store them in a list while True: while True: try: r = requestQueue.get(block=False) except Q.Empty: break else: reqs.append(r) # Mimic production of R. It sends back a supposed unit of R when time for production is over for index, request in enumerate(reqs): if time.time() - request['time'] >= 20: request['response'].put({'R': 'value'}) # Mark request for deletion after it has been services reqs[index] = None # Remove completed requests reqs = [x for x in reqs if x]
Basically, I find out how frequently do the workers require R by finding the avg time, RequestRate, between successive calls to get_request function (check comments in get_request function). Using that, I try to predict how many units I would need to procure to keep up (see the comments in send_request function). Hence, if RequestRate is large, lesser requests would be sent to produce R. However, I run into a logical flaw here. The thing is, the get_request function, as mentioned, blocks until a unit of R is recieved. Hence, if production of R is too low, the function will block more frequently for longer times and RequestRate will become larger and larger. This would mean that the production will slow even more since the send_function considers the large RequestRate to mean that not many units of R are required, when infact the converse is True. This issue will be solved if somehow I could remove the time the workers spend inside the get_request function when calculating RequestRate. I cannot just simply calculate the time each worker spends inside the function and subtract that when calculating RequestRate because there could be multiple workers running. In that case RequestRate would most probably be smaller than the time each worker spent inside the function. So my question, as stated in the title, is finding out how frequently (in seconds) a class method is called ignoring the time spent in the function itself given that the function can be accessed by multiple instances concurrently. If this is not possible, can someone suggest a way for me to achieve my original goal, i.e, predicting how much R to produce so that the workers block the least amount of time and it expires the least number of times?  |

This is my database { "Users" : { "Customer" : { "0awTFPGUkIdzAaZEgYZMmGv1zwk1" : { "mail" : "1@gmai.com", "username" : "1234" } }, "Driver" : { "S04QBZx3PxYaLfDWBC3j3otM5ml1" : { "mail" : "m.yusuf7423@gmail.com", "username" : "YUSUF" } } } }
Also now my app started to crash and I get this problem in logcat Process: com.example.deliveryapp, PID: 12806 java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference
Edit:in the layout page I added On-click option to call update so now it doesn't crash and doesn't throw any error but now nothing happens at all like I can here the sound of the button being clicked(which happens when there is an onclick function) but nothing happens at all this is the layout of that button <Button android:id="@+id/editinfo" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginStart="228dp" android:layout_marginLeft="228dp" android:layout_marginTop="456dp" android:onClick="update" android:text="edit" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" />

| Use AD B2C and MSAL v2 with Angular allowing selective unprotected Web API calls Posted: 26 Jun 2021 09:23 AM PDT My goal is to allow users to freely browse an Angular 11+ site, reading data called from a .NET Web API as they navigate. Only users who wish to post data or access particular features would need to sign up and sign in, using AD B2C identity services. Accordingly, controllers in the backend app service are marked with [Authorize] or [AllowAnonymous] as appropriate. The site successfully supports browsing and posting for signed-in users, copying the approach from the AzureAD sample. export function MSALInterceptorConfigFactory(): MsalInterceptorConfiguration { const protectedResourceMap = new Map<string, Array<string>>(); protectedResourceMap.set(apiConfig.uri, apiConfig.scopes); return { interactionType: InteractionType.Redirect, protectedResourceMap }; }
However, using that approach, the Msal's httpInterceptor evidently fires for every database call, forcing a B2C signup/login event on all endpoints, defeating the effort to support anonymous browsing. MSAL v1 apparently supported an unprotectedResource array, but that was deprecated for v2. It also apparently supported the use of null patterns such as const resourceMap: [string, string[]][] = [ [`${apiBaseUrl}/health`, null], [`${apiBaseUrl}`, ['scope1', 'scope2']], ];
Since that v1 object has a different shape I tried it this way in v2, but to no avail const protectedResourceMap = new Map<string, Array<string>>(); protectedResourceMap.set(apiConfig.uri + '/myreadabledata', []); protectedResourceMap.set(apiConfig.uri, apiConfig.scopes);
I've tried other approaches such as setting the protectedResourceMap exclusively for the controllers that require authorization. That failed as well. const protectedResourceMap = new Map<string, Array<string>>(); protectedResourceMap.set(apiConfig.uri + '/mycloseddata1' , apiConfig.scopes); protectedResourceMap.set(apiConfig.uri + '/mycloseddata2' , apiConfig.scopes);
What is the correct way to achieve this?  |
| How to use stencil buffer to achieve hierarchical clipping Posted: 26 Jun 2021 09:24 AM PDT What I'm trying to achieve is illustrated on the image below: 
Let's say we have stencil buffer in a state so only red section is filled at the moment. What actions do I need to perform when I update stencil buffer with a section which is marked yellow, so in the end only green section would be the final state of the stencil buffer? I need this to achieve nested element content clipping, to prevent content of the element to be rendered beyond the boundaries of them both combined. So far I have tried various boolean operations involving stencil test to no avail, which brought more confusion than any progress. Please note that scissor test is not actual for this task, because elements may have arbitrary shape and rotation.  |
| Symfony getData event subscriber is null Posted: 26 Jun 2021 09:24 AM PDT I know this question has been asked already a couple of times, but there hasn't been an answer that actually helped me solving my problem. I've got three EventSubscribers for three Dropdowns who are dependent on each other. So in my FormType I say: public function buildForm(FormBuilderInterface $builder, array $options) { // solution showmethecode $pathToAgencies = 'agencies'; // $builder ->addEventSubscriber(new AddChannel1Subscriber($pathToAgencies)) ->addEventSubscriber(new AddChannel3Subscriber($pathToAgencies)) ->addEventSubscriber(new AddAgencySubscriber($pathToAgencies)); }
and one of my EventSubscribers looks like that: ... ... public static function getSubscribedEvents() { return array( FormEvents::PRE_SET_DATA => 'preSetData', FormEvents::PRE_SUBMIT => 'preSubmit' ); } private function addChannel1Form($form, $channel1s = null) { $formOptions = array( 'class' => 'AppBundle:Channel1', 'property' => 'name', 'label' => 'label.channel1s', 'empty_value' => 'label.select_channel1s', 'mapped' => false, 'expanded' => false, 'translation_domain' => 'UploadProfile', 'multiple' => true, 'required' => false, 'attr' => array( 'class' => 'channel1s' ), ); if ($channel1s){ $formOptions['data'] = $channel1s; } $form->add('channel1s', 'entity', $formOptions); } public function preSetData(FormEvent $event) { $data = $event->getData(); $form = $event->getForm(); if (null === $data) { return; } $accessor = PropertyAccess::createPropertyAccessor(); $agency = $accessor->getValue($data, $this->pathToAgency); $channel1s = ($agency) ? $agency->getChannel3s()->getChannel1s() : null; $this->addChannel1Form($form, $channel1s); } public function preSubmit(FormEvent $event) { $form = $event->getForm(); $this->addChannel1Form($form); } ...
Now I'm getting the error "Attempted to call an undefined method named "getChannel3s" of class "Doctrine\Common\Collections\ArrayCollection"." and (I think) this is because my $data in my preSetData is NULL but I don't know why it's null. Am I looking at the wrong spot or where is my mistake here?  |
| Laravel DB::table AND statement? Posted: 26 Jun 2021 09:26 AM PDT I'm very new to Laravel and don't quite understand the DB::table method in conjuction with an AND clause. So I have this query at the moment: $query = DB::select( DB::raw("SELECT * FROM tablethis WHERE id = '$result' AND type = 'like' ORDER BY 'created_at' ASC"));
It is working, but I'd like to use Laravel's Query Builder to produce something like: $query = DB::table('tablethis')->where('id', '=', $result)->where('type', '=', 'like')->orderBy('created_at', 'desc')
But this seems to ignore the second where() completely. So, basically how do I make this work?  |
| .htaccess redirect all pages to new domain Posted: 26 Jun 2021 09:23 AM PDT Which redirect rule would I use to redirect all pages under olddomain.example to be redirected to newdomain.example? The site has a totally different structure, so I want every page under the old domain to be redirected to the new domain index page. I thought this would do (under olddomain.example base directory): RewriteEngine On RewriteRule ^(.*)$ http://newdomain.example/ [R=301]
But if I navigate to olddomain.example/somepage I get redirected to newdomain.example/somepage. I am expecting a redirect only to newdomain.example without the page suffix. How do I keep the last part out?  |
