QUESTION
I want to check the reachability of about 100 ips addresses and set a limit of concurrent tasks with semaphore. But now I'm not sure how this works exactly or why it doesn't work in the code example. As I could observe the function "task_reachable" is still executed correctly. if no address is reachable, then in the "try_ssh_connection" "all" tasks are executed in parallel and this makes the code incredibly slow.
...ANSWER
Answered 2022-Mar-22 at 14:05Your problem is each running instance of boundary_task
has its own semaphore.

QUESTION
I want to download/scrape 50 million log records from a site. Instead of downloading 50 million in one go, I was trying to download it in parts like 10 million at a time using the following code but it's only handling 20,000 at a time (more than that throws an error) so it becomes time-consuming to download that much data. Currently, it takes 3-4 mins to download 20,000 records with the speed of 100%|██████████| 20000/20000 [03:48<00:00, 87.41it/s]
so how to speed it up?
ANSWER
Answered 2022-Feb-27 at 14:37If it's not the bandwidth that limits you (but I cannot check this), there is a solution less complicated than the celery and rabbitmq but it is not as scalable as the celery and rabbitmq, it will be limited by your number of CPU.
Instead of splitting calls on celery workers, you split them on multiple processes.
I modified the fetch

with an Executor will cause your process to block until the jobs in the executor are completed; since they’re running infinite event loops, they will never complete and your Executor will never unblock.
Instead, just use the executor to kick off the jobs, and run your stuff afterwards. When you’re finally done, call .shutdown()
to wait for processes to exit:

QUESTION
I'm using aiohttp for async http requests, and I can't figure out how to get the response from a server when the request returns a 4XX error.
...ANSWER
Answered 2022-Jan-24 at 17:31The reason this issue is occuring is because of a side effect with response.ok
. In older versions of aiohttp (3.7 and below), response.ok
called response.raise_for_status()
, which closed the TCP session and resulted in not being able to read the server's response anymore.
To fix this, you simply need to move response = await resp.json()
above the response.ok
line, that way you save the response beforehand. For example:

Install aiohttp
You can use aiohttp like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
