TypeScript Compiler API: get type structure

Asyncio big list of Task with sequential combine run_in_executor and standard Coroutine in each

QUESTION

TypeScript Compiler API: get type structure

Asked 2021-Aug-02 at 15:08

Is there an API method to get the "bottomed out" type information from the TypeScript compiler? Example:

I've found a solution. It doesn't use the TypeScript compiler API, directly, but rather the excellent ts-morph library, a wrapper for the compiler API which simplifies many tasks. Here's some example code, where the test.ts file contains the example code from my question above.

QUESTION

Asyncio big list of Task with sequential combine run_in_executor and standard Coroutine in each

Asked 2021-Jan-15 at 20:29

I need to handle list of 2500 ip-addresses from csv file. So I need to create_task from coroutine 2500 times. Inside every coroutine firstly I need to fast-check access of IP:PORT via python module "socket" and it is a synchronous function want to be in loop.run_in_executor(). Secondly if IP:PORT is opened I need to connect to this socket via asyncssh.connect() for doing some bash commands and this is standart asyncio coroutine. Then I need to collect results of this bash commands to another csv file.

Additionaly there is an issue in Linux: system can not open more than 1024 connections at same time. I think it may be solved by making list of lists[1000] with asyncio.sleep(1) between or something like that.

I expected my tasks will be executed by 1000 in 1 second but it only 20 in 1 sec. Why?

Little working code snippet with comments here:

Hands-on tutorial and definition of Property Based Testing: 🏁 see tutorial. Or directly try it online on our pre-configured CodeSandbox. Property based testing frameworks check the truthfulness of properties. A property is a statement like: for all (x, y, ...) such that precondition(x, y, ...) holds predicate(x, y, ...) is true. Install the module with: yarn add fast-check --dev or npm install fast-check --save-dev.
