            Issues transferring zone file with dnspython
            Asked 2020-Nov-14 at 19:47

            I am attempting to use python to pull down a zone file. After going through hoards of documentation, I am still stuck on one line of code:


            I get the following error:

            socket.error: [Errno 111] Connection refused

            I've hardcoded ns2.megacorpone.com's IP to isolate any problems. For some reason this connection continues to refuse. Is anyone able to shed some light on this problem?

            Thanks all

            Running the same command with the domain name instead of IP worked.

            What is the meaning of messages outstanding to a subscriber in the context of PubSub subscription acknowledge deadlines and re-delivery?
            Asked 2020-Jun-30 at 18:18

            We are using Google PubSub in a 'spiky' fashion where we publish millions of small messages (< 10k) in a short time (~ 10 mins), spin up 2k GKE pods with 10 worker threads each that use synchronous pull and acknowledge PubSub service calls to work through the associated subscription (with a 10 minute acknowledgement deadline). The Stack Driver graph for the subscription backlog will show a spike to 10M messages and then a downward slope to 0 in around 30 minutes (see below).
            We noticed an increase of message re-delivery as the size of these backlogs grew from 1M to 10M from below 1% to beyond 10% for certain hours.

            Coming from the GAE Task Pull queue world, we assumed that a worker would "lease" a message by pulling a message from the PubSub subscription where, starting at the time of pull, a worker would have 10 minutes to acknowledge to message. What appears to be happening however, after adding logging (see below for example of a re-published message), is that it is not the time from pull to ack that matters, but the time from publishing the message to acknowledgement.

            Is this the right understanding of PubSub acknowledgement deadline, and subsequent redelivery behavior?

            If so, should we be making sure the subscription's message backlog should only grow to a size that worker threads are able to process and acknowledge within the time configured for the subscription's acknowledgement deadline to get re-delivery rates to < 0.1% on average? We can probably have the publisher apply some sort of back-pressure based on the subscription backlog size although the GAE Pull Task Queue leasing behavior seems more intuitive.

            Also, the wording in https://cloud.google.com/pubsub/docs/subscriber#push-subscription, under "Pull subscription": "The subscribing application explicitly calls the pull method, which requests messages for delivery" seems to imply that the acknowledgment timeout starts after the client pull call returns a given message?

            Note: we use the Python PubSub API (google-cloud-pubsub), although not the default streaming behavior as this caused "message hoarding" as described in the PubSub docs given the large amount of small messages we publish. Instead we call subscriber_client.pull and acknowledge (which seems thin wrappers around the PubSub service API calls)



            Answered 2020-Jun-30 at 17:17

            The ack deadline is for the time between Cloud Pub/Sub sending a message to a subscriber and receiving an ack call for that message. (It is not the time between publishing the message and acking it.) With raw synchronous pull and acknowledge calls, subscribers are responsible for managing the lease. This means that without explicit calls to modifyAckDeadline, the message must be acked by the ack deadline (which defaults to 10 seconds, not 10 minutes).

            If you use one of the Cloud Pub/Sub client libraries, received messages will have their leases extended automatically. The behavior for how this lease management works depends on the library. In the Python client library, for example, leases are extended based on previous messages' time-to-ack.

            There are many reasons for message redelivery. It's possible that as the backlog increases, load to your workers increases, increasing queuing time at your workers and the time taken to ack messages. You can try increasing your worker count to see if this improves your redelivery rate for large backlogs. Also, the longer it takes for messages to be acked, the more likely they are to be redelivered. The server could lose track of them and deliver them once again.

            There is one thing you could do on the publish side to reduce message redeliveries - reduce your publish batch size. Internally, ack state is stored per batch. So, if even one message in a batch exceeds the ackDeadline, they may all be redelivered.

            Message redelivery may happen for many other reasons, but scaling your workers could be a good place to start. You can also try reducing your publish batch size.

            How can I stop enemies from overlapping pygame
            Asked 2020-Jun-20 at 22:27

            I'm trying to find a way to have enemies track the player in my 2d game (pygame) but not clump up

            Currently, when I shoot at them, the bullet collides into and damages all of the enemies that are clumped. I would like it to be a hoard but spread out just enough to where I can't hit every single enemy at once

            It looks like this

            Here's a gif of them clumping

            I'm not sure how I would get the individual values of the enemies' positions so I can move them when they collide or how I should move them

            This is what I currently have for the enemies to track the player:



            Answered 2020-Jun-20 at 21:52

            You can do collision detection between the enemies, to determine which ones are too close. You'll also need to change their behavior, to decide what to do when they actually get too close.

            If you know you'll never get too many enemies, you can try comparing every enemy with every other enemy. This will take O(N^2) work, but that is probably OK if N is limited.

            If you are comparing every enemy to every other anyway, you have a wider variety of options than just "collision detection": like the Boids algorithm (which does collision avoidance instead).

            Instead of writing JSON.stringify(editMessage, null, 2) into your JSON you might want to edit the content of it first.

            You can replace the content of your file with data.replace() method.

            Display Sub content from ngFor Array on Click
            Asked 2019-Sep-14 at 01:56

            In my project I have, each of the card values displayed on the screen they are looped over from JSON using ngFor. The desired goal is when a user clicks on a card it displays just the information about that card from the JSON while just showing the content in my div with an *ngIf. I have an animation created to fade in a mask where I want the content displayed. Currently if you click on the card it just shows the array of thumbnails. I'm not getting any errors or anything to go on. I've tirelessly searched for answers on how to accomplish showing an individual key on a click. I need the Card image, name, and description displayed for a single card at a time. I feel like I've hit a road block and am not Googling the correct description. Please let me know if I need to further clarify. Thank you for any direction you can offer.

            Your toggle function isn't right.

            You are sending index i as an argument from your template (click)="toggleCard(i)" but aren't capturing it in your component.

            You should capture that index i because it uniquely identifies the clicked card. If not how will you know which card is clicked?

            DotNet Core 2.1 hoarding memory in Linux
            Asked 2019-Jul-04 at 06:38

            I have a websocket server that hoards memory during days, till the point that Kubernetes eventually kills it. We monitor it using prometheous-net.

            Disclaimer: I am no .NET Wizard.

            But you should do two things to go with Kubernetes best practices:

            1. Define sensible resource limits for your app. If the app does not need more than 200MB memory define a resource limit to prevent the app from consuming all available host memory. But be aware that the Unix API to get available memory is not capable of processing the cgroup the process has and always outputs the host memory no matter what your cgroup says.

            2. Tell your app what this resource limit is. It seems like your app does not "feel the need" to free memory as there is plenty. Almost all applications, and frameworks as well, have a switch to define the maximum memory to be consumed. Tell your app this limit, and it will "see" memory pressure and perform a full GC (what I guess could be the problem here)

            C# StringBuilder Continue Writing to a File instead of Replacing it
            Asked 2019-Jun-14 at 03:28

            I would like to continue writing to an existing text file in my StringBuilder instead of replacing it with a new file.

            Reason: To have ongoing logging to file from the datatable and clear it during the process to prevent hoarding up a big amount of memory if the program runs for a long time.

            Is it possible?

            Below is my current code which replaces with a new text file.

            How can I "discover" the COM object behind the ref counted handle in WinDbg?
            Asked 2018-Nov-19 at 14:53

            I'm investigating a memory leak via a WinDbg DMP file. I've found that there are many instances of AmazeType on the heap, and although it is an excellent type, there are way too many in existence. I'd like to know who is hoarding them.

            !gcroot-ing AmazeType leads me to a "ref counted handle". This makes sense, as the list of awesome type is stored in a property of a COM object instance, via a COM Callable Wrapper.

            I haven't done this in a 64-bit dump, only a 32-bit dump, but hopefully this will be of some help to you.

            (I realise this is likely to be too late for you, but hopefully it will help somebody else.)

            In my experience, going from the COM object to the .NET object runs like this. Therefore, going from the .NET object to the COM object is a case of reversing the process. I'm using examples from a real dump, but censored and renamed.

            From COM to .NET object.

            You have your COM object which has a field in it, which may look like this:

            I had similar issue. Try installing a correct version of LLDB. SOS plugin from specific dotnet version is linked to a specific version of LLDB. For example dotnet 2.0.5 is linked with LLDB 3.6, v.2.1.5 is linked with LLDB 3.9. Also this document might be helpful: Debugging CoreCLR

            Note not all versions of LLDB are available for some OS. For example LLDB 3.6 is unavailable on Debian but available on Ubuntu.

            Multiple integer overflows in the (1) malloc and (2) calloc functions in Hoard before 3.9 make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows on implementing code via a large size value, which causes less memory to be allocated than expected.
