            Springboot 2.6.0 / Spring fox 3 - Failed to start bean 'documentationPluginsBootstrapper'
            Asked 2022-Mar-25 at 06:14

            I'm trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.

            In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux dependencies.

            I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.

            I figured out that these lines in our build.gradle file are the origin of the problem.



            Answered 2022-Feb-08 at 12:36

            This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.

            As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.

            The short answer is "there is currently no solution." If you want your apps to run on iOS 12 and earlier, you can't use the async/await calls, unless you want to write 2 versions of all your async code, one that runs on iOS < 15, and the other that runs on iOS ≥ 15.

            As George mentions in his comment, Apple is trying to figure out how to "back-depoloy" async/await support. If they are able to do that, you will be able to use the modern approach with older versions, but I would bet Apple will not go back as far as iOS 12.


            See Bradley's comment below. The best you will get is async/await support in iOS 13, if Apple is able to pull that off. From the link Bradley posted, iOS 12 definitely won't be supported.

            Deps File Missing for Dotnet 6 Integration Tests

            Before I start, I've tried all suggestions from the following and none work:

            Integration testing ASP.NET Core with .NET Framework - can't find deps.json


            So I'm trying to write some integration tests for dotnet 6. However, my WebApplicationFactory throws the following error:

            System.InvalidOperationException: Can't find '/repos/subscription-info-api/tests/SubscriptionInfoApi.Tests.Integration/bin/Debug/net6.0/...

            System.InvalidOperationException Can't find '/repos/subscription-info-api/tests/SubscriptionInfoApi.Tests.Integration/bin/Debug/net6.0/testhost.deps.json'. This file is required for functional tests to run properly. There should be a copy of the file on your source project bin folder. If that is not the case, make sure that the property PreserveCompilationContext is set to true on your project file. E.g 'true'. For functional tests to work they need to either run from the build output folder or the testhost.deps.json file from your application's output directory must be copied to the folder where the tests are running on. A common cause for this error is having shadow copying enabled when the tests run. at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.EnsureDepsFile() at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.EnsureServer() at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.CreateDefaultClient(DelegatingHandler[] handlers) at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.CreateDefaultClient(Uri baseAddress, DelegatingHandler[] handlers) at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.CreateClient(WebApplicationFactoryClientOptions options) at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.CreateClient() at SubscriptionInfoApi.Tests.Integration.UnitTest1.Test1() in /repos/subscription-info-api/tests/SubscriptionInfoApi.Tests.Integration/UnitTest1.cs:line 14 at SubscriptionInfoApi.Tests.Integration.UnitTest1.Test1() in /repos/subscription-info-api/tests/SubscriptionInfoApi.Tests.Integration/UnitTest1.cs:line 16 at Xunit.Sdk.TestInvoker1.<>c__DisplayClass48_0.<b__1>d.MoveNext() in /_/src/xunit.execution/Sdk/Frameworks/Runners/TestInvoker.cs:line 264 --- End of stack trace from previous location --- at Xunit.Sdk.ExecutionTimer.AggregateAsync(Func1 asyncAction) in //src/xunit.execution/Sdk/Frameworks/ExecutionTimer.cs:line 48 at Xunit.Sdk.ExceptionAggregator.RunAsync(Func`1 code) in //src/xunit.core/Sdk/ExceptionAggregator.cs:line 90

            Using the hint from @jewelsea I was able to use a custom chain. I've done this from a "catcher" Pane which is added to the front of the StackPane. This then builds a chain using all the children, in reverse order, excluding itself.

            How to get message from logging function?
            Asked 2022-Jan-18 at 13:27

            I have a logger function from logging package that after I call it, I can send the message through logging level.

            I would like to send this message also to another function, which is a Telegram function called SendTelegramMsg().

            How can I get the message after I call the funcion setup_logger send a message through logger.info("Start") for example, and then send this exatcly same message to SendTelegramMsg() function which is inside setup_logger function?

            Answered 2022-Jan-06 at 15:59

            Picking up the idea suggested by @gold_cy: You implement a custom logging.Handler. Some hints for that:

            • for the handler to be able to send message via a bot, you may want to pass the bot to the handlers __init__ so that you have it available later
            • emit must be implemented by you. Here you'll want to call format which gives you a formatted version of the log record. You can then use that message to send it via the bot
            • Maybe having a look at the implementation of StreamHandler and FileHandler is helpful as well

            Can I allocate a series of variables on the stack based on template arguments?
            Asked 2022-Jan-08 at 17:53

            In a piece of code I'm writing, I receive packets as uint8_t * and std::size_t combination. I can register functions to call with these two parameters, based on which file descriptor the packet was received from. I use an std::map > handlers to keep track of which function to call.

            I would like to be able to (indirectly) register functions with arbitrary arguments. I already have a function like this to transform from the uint8_t * and std::size_t to separate variables:

            It's possible, just annoying to write.

            First you need a trait to get parameters from a function type:

            Cancelling an async/await Network Request
            Asked 2022-Jan-03 at 22:23

            I have a networking layer that currently uses completion handlers to deliver a result on the operation is complete.

            As I support a number of iOS versions, I instead extend the network layer within the app to provide support for Combine. I'd like to extend this to now also a support Async/Await but I am struggling to understand how I can achieve this in a way that allows me to cancel requests.

            Answered 2021-Oct-10 at 13:42

            async/await might not be the proper paradigm if you want cancellation. The reason is that the new structured concurrency support in Swift allows you to write code that looks single-threaded/synchronous, but it fact it's multi-threaded.

            Take for example a naive synchronous code:

            Managing handlers when storing React+Gatsby static App on GCP

            My React App is already running on GCP engine. Navigation and all the pages look fine but direct links are causing issues - for example, if I open myWebsite.com/vacancies, I'll get the error log saying that Static file referenced by handler not found: public/vacancies//index.html. Here's my app.yaml handlers config:



            Answered 2021-Sep-08 at 12:40

            This error is mainly caused by a problem in the app.yaml file, it can be caused if static file handlers redirects to a file that does not exist or the file name mentioned is incorrect. Please make sure you are using an updated version for the language and the name mentioned in the file is correct.

            You can refer to the public Documentation where reference for the App.yaml file is provided, you can also refer to the stackoverflow answers for the post1 and post2 where a brief description for the app.yaml handlers configuration has been provided for the static website.
