            expo sdk 41 - unable to build standalone apk/aab
            Asked 2021-May-08 at 18:04

            I recently upgraded my expo's SDK version from 35 to 41 and also upgraded expo-cli from 3.18.5 to 4.4.3. However, when I try to build a standalone APK/AAB, I'm getting the following error:
            × Build failed. Standalone build failed!
            In order to understand what was exactly causing this issue, I examined the Gradle logs of build Gradle on expo, and here's what I was able to find.



            Answered 2021-May-08 at 18:04

            There are two major reasons for this cause.

            1. Setting enableDangerousExperimentalLeanBuils to true.
            2. Missing expo-splash-screen package.

            The error is because it's(Gradle build) looking for expo-modules-splashscreen package, which is supposedly moved out of expo's main module in SDK 41, hence needs to be separately installed. In order to fix this, there are two workarounds:

            1. Remove enableDangerousExperimentalLeanBuilds property. (Not tested)
            2. Install expo-splash-screen using npm install expo-splash-screen.(Tested and working)



            Discord bot doesn't send an image
            Asked 2021-Apr-21 at 22:13

            I want my bot to send an image from given url with caption got from String(), but with SendFileAsync() it totally doesn't work. Is there another method for sending images from internet or I just screwed up something in here?



            Answered 2021-Apr-21 at 22:13

            To use SendFileAsync, you need to have the file locally. If you want to send a URL without downloading, just use SendMessageAsync. Discord will preview the image from the URL (unless the user disabled that manually).

            Otherwise, this would help:



            Flink-RocksDB behaviour after task manager failure
            Asked 2021-Apr-02 at 08:05

            I am experimenting with my new Flink cluster(3 Different Machines-> 1 Job Manager, 2-> Task Managers) using RocksDB as State Backend however the checkpointing behaviour I am getting is a little confusing.

            More specifically, I have designed a simple WordCount example and my data source is netcat. When I submit my job, the job manager assigns it to a random task manager(no replication as well). I provide some words and then I kill the currenlty running task manager. After a while, the job restarts in the other task manager and I can provide some new words. The confusing part is that state from the first task manager is preserved even when I have killed it.

            To my understanding, RocksDB maintains its state in a local directory of the running task manager, so what I expected was when the first task manager was killed to lose the entire state and start counting words from the beginning. So Flink seems to somehow maintain its state in the memory(?) or broadcasts it through JobManager?

            Am I missing something?



            Answered 2021-Apr-02 at 08:05

            The RocksDB state backend does keep its working state on each task manager's local disk, while checkpoints are normally stored in a distributed filesystem.

            If you have checkpointing enabled, then the spare task manager is able to recover the state from the latest checkpoint and resume processing.



            How to force Apache Flink using a modified operator placement?
            Asked 2021-Mar-24 at 10:00

            Apache Flink is distributes its operators on available, free slots on the JobManagers (Slaves). As stated in the documentation, there is the possibility to set the SlotSharingGroup for every operator contained in an execution. This means, that two operators can share the same slot, where they are executed later.

            Unfortunately, this option only allows to share the same group but not to assign a streaming operation to a specific slot.

            So my question is: What would be the best (or at least one) way to manually assign streaming operators to specific slots/workers in Apache Flink?



            Answered 2021-Mar-17 at 17:08

            You could disable the chaining via (disableChaining()) and start a new chain to isolate it from others via (startNewChain()). You can play with Flink Plan Visualizer to see if your plan has isolated operators. These modifiers applied affter the operator. Example:

            How to create a background job in AEM as a Cloud?
            Asked 2021-Mar-12 at 11:48

            I want to create a daily background job to be executed by AEM. I read an aem document and apache sling official site, and I thought I need two classes.

            • a service class that register the job to JobManager.
            • a consumer class that do the job.

            So I tried these code, but my job was not executed.

            service class



            Answered 2021-Mar-12 at 11:48

            If you annotate a method with @Activate it will be called when the component starts.

            @Activate public void startScheduledJob()

            I guess you want your job to run on startup. Another option would be to let MyJobService be a servlet and call it from outside.



            How to Exclude Configuration from Spring IT?
            Asked 2021-Mar-10 at 12:53

            It seems this is a very straightforward question, especially since it already works sometimes in my application. I have no idea why that is, so if I've missed some important information, just tell me.

            First of all, I have a test case:



            Answered 2021-Mar-10 at 12:53

            So the problem in this case is that Applications in close vicinity import each other, but not in the way it would make sense.

            There was a second application without the exclude, and so Spring figured it could just add the excluded class anyways. I wanted to have feature / package based Spring test application, this seems not to be possible. I merged them into one big application and now exclusion works normally.



            Rust Closure not allowing access to outside data
            Asked 2021-Feb-22 at 07:04

            I am working on implementing a Shell in Rust. I am using the ctrlc crate for handling SIGINT, and my intention is to forward the SIGINT signals received to the process currently running in the shell (the foreground job):



            Answered 2021-Feb-22 at 07:04

            If you look at the documentation, set_handler requires a 'static callback, meaning the callback must be able to live forever.

            Here your callback includes a reference to self, meaning it can't outlive self ('a), which is definitely not 'static.

            The simplest way to fix this issue is to pass only "owned" data to the callback, e.g.



            Multiple "k8s-ha-app1-jobmanager" configmaps on every Flink job run
            Asked 2021-Feb-18 at 11:00

            I have a Flink session cluster on top of Kubernetes and recently I switched from the ZK based HA to Kubernetes HA.

            Reading through

            I can observe on the Flink namespace the configmaps for each resource as described in the docs above:



            Answered 2021-Feb-16 at 16:49

            The way Flink works internally is that the Dispatcher creates for every submitted job a dedicated JobMaster component. This component needs a leader election and for this purpose it creates a k8s-ha-app1--jobmanager config map. This is the reason why you see multiple xyz-jobmanager ConfigMaps being created.

            The reason why these ConfigMaps are not cleaned up is that this currently happens only when the whole cluster is shut down. This is a limitation and the Flink community has created FLINK-20695 in order to fix it. The idea is that the JobMaster related ConfigMaps can be deleted after the job has reached a terminal state.

            A bit related is another limitation which hampers the proper clean up in case of a session cluster. If the cluster is shut down with a SIGTERM signal then it is currently not guaranteed that all resources are cleaned up. See FLINK-21008 for more information.
