问题 The 'request' module has been a long-time standard for Node.js. They have recently deprecated the library. I am starting a new project, and looking for the best solution to do my networking. I started off using the native 'https' module, but ran into problem after problem. Using the request module seemed to be easy and work just fine. There are also many other libraries to replace the request module. Generally speaking, you should avoid using deprecated libraries when possible. But does that

问题 According to cppreference, the trait std::is_literal_type is deprecated in C++17. The question is why and what is the preferred replacement for the future to check whether a type is a literal type. 回答1: As stated in P0174: The is_literal type trait offers negligible value to generic code, as what is really needed is the ability to know that a specific construction would produce constant initialization. The core term of a literal type having at least one constexpr constructor is too weak to be

问题 We have a Java project. We enable -Xlint (enable warnings) and -Werror (treat warning as error) flags for javac , to make sure our code is warning-free. Recently we decide to deprecate a class. The problem is in some cases @SuppressWarnings("deprecation") will not suppress the deprecation warning at all, resulting in build failure. Below is a list of use cases that I ran into: Imported in other non-deprecated classes. Imported in other deprecated classes. Parent class. Type parameter. For

问题 I have removed the UIWebView from my app. But when I uploaded the iOS app on iTunes I still got the same message "Re: ITMS-90809: Deprecated API Usage - Apple will stop accepting submissions of apps that use UIWebView APIs" I have searched for UIWebView globally in the project and there are no search results. That simply means UIWebView is removed. I have updated the pods too. I have verified the presence of UIWebView in the app archive using below code: grep -r "UIWebView" . The response is

问题 I am using the following configuration snippet in my Java/Kotlin Android project in the app/build.gradle file: gradle.projectsEvaluated { tasks.withType(JavaCompile) { options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation" } } It generates a verbose output of Lint warnings in .java files when the project is compiled. I would like to achieve the same for .kt files. I found out that Kotlin has compiler options: gradle.projectsEvaluated { tasks.withType(org.jetbrains.kotlin.gradle

问题 A lot of the functions in asyncio have deprecated loop parameters, scheduled to be removed in Python 3.10. Examples include as_completed(), sleep(), and wait(). I'm looking for some historical context on these parameters and their removal. What problems did loop solve? Why would one have used it in the first place? What was wrong with loop ? Why is it being removed en masse? What replaces loop , now that it's gone? 回答1: What problems did loop solve? Why would one have used it in the first
