Here a modified version of what I posted at https://stackoverflow.com/a/67847257/893857 since it also solves this problem. I found a solution using nest_asyncio. If one has the following async example script: import asyncio import nest_asyncio async def bar(x): return x + 1 async def foo(): import ipdb; ipdb.set_trace() if __name__==”__main__”: loop = asyncio.get_event_loop() nest_asyncio.apply(loop) loop.run_until_complete(foo()) One … Read more
Python and JavaScript don’t do CPU threads (well, Python can do threads, but that’s not relevant here, because Python’s thread stuff isn’t inherently await-able). So they fake threading with “event loops”. C++ is a low-level language that knows what CPU threads are and expects to make use of them. As such, when you co_await on … Read more
After playing with the code I was able to figure it out. Here is the solution. public async Task DeleteSchoolTask(int schoolNumber, int taskDetailId) { var result = await GetTaskTypeAndId(taskDetailId); int taskId = result.Item1; string taskType = result.Item2; // step 1: delete attachment physically from server var fileService = new FileService(Logger, CurrentUser); var relativeFilePath = $”{schoolNumber}\\{Consts.RM_SCHOOL}\\{taskDetailId}”; … Read more
To answer your questions more directly: ConfigureAwait(true): Runs the rest of the code on the same thread the code before the await was run on. Not necessarily the same thread, but the same synchronization context. The synchronization context can decide how to run the code. In a UI application, it will be the same thread. … Read more
As per FastAPI’s documentation: When you declare a path operation function with normal def instead of async def, it is run in an external threadpool that is then awaited, instead of being called directly (as it would block the server). also, as described here: If you are using a third party library that communicates with … Read more
The easiest way is to start from the entry node of the graph, as if you were writing the code by hand. In order to solve the join problem, you can not use a recursive solution, you need to have a topological ordering of your graph, and then build the graph according to the ordering. … Read more
Look for Step module. It can chain asynchronous functions calls and pass results from one to another.
This is a great question which really isn’t explained well in most texts about C# and async. I searched for this for ages thinking I could and should maybe be implementing my own async I/O methods. If a method/library I was using didn’t have async methods I thought I should somehow wrap these functions in … Read more
The response body is blank because the @Async annotation is used at findEmail method of UserRepository class, it means that there is no data returned to the following sentence User user = userRepository.findByEmail(email); because findByEmail method is running on other different thread and will return null instead of a List object. The @Async annotation is … Read more
