QUESTION
I have a pure python package(let's call it main) that has a few functions for managing infrastructure. Alongside, I have created a FastAPI service that can make calls to the main module to invoke functionality as per need.
For logging, I'm using loguru. The API on startup creates a loguru instance, settings are applied and a generic UUID is set (namely, [main]). On every incoming request to the API, a pre_request function generates a new UUID and calls the loguru to configure with that UUID. At the end of the request, the UUID is set back to default UUID [main].
The problem that I'm facing is on concurrent requests, the new UUID takes over and all the logs are now being written with the UUID that was configured latest. Is there a way I can instantiate the loguru module on every request and make sure there's no cross logging happening for parallelly processed API requests?
Implementation:
In init.py of the main package:

I'm not able to disable the traceback on exceptions even after setting LOGURU_BACKTRACE environment variable as False. I've also tried logger.configure() method like this.
ANSWER
Answered 2022-Feb-28 at 11:15The backtrace attribute controls the length of the traceback (if enabled, Loguru displays the entire traceback instead of stopping at the try/except frame like the standard exception does).
However, Loguru respects the sys.tracebacklimit value. You can disable traceback by settings it to 0:

For a third party library* I have to provide a function which consumes some data. My implementation of the consumption requires the data to be posted to an API. So I came up with this structure below:
...ANSWER
Answered 2022-Feb-26 at 21:07It depends on the context manager. In the code you wrote, the HTTPClient you created stays alive because the function it returns maintains a reference to it, even though the variable http_client defined in consumer_provider goes out of scope.
However, HTTPClient.__exit__ is still called before consumer_provider returns, so the consumer function may not work as intended.

QUESTION
is there a way clear the log file before using it with the python log library 'loguru'?
Thanks!
...ANSWER
Answered 2022-Feb-20 at 11:21Loguru API does not have the ability to remove/clean up log files. Instead of that, you could either use open('output.log', 'w').close() if you want to erase all contents of the log file. Or check the ability to use log rotation in Loguru if it's suitable for your use case (something like that logger.add("file_{time}.log"))

I'm still reaseaching about Loguru, but I can't find an easy way to do this. I want to use the default options from Loguru, I believe they are great, but I want to add information to it, I want to add the IP of a request that will be logged.

Answered 2022-Feb-06 at 14:13I make the same question in the Github Repository and this was the answered by Delgan (Loguru maintainer):
I think you simply need to add() your handler using a custom format containing the extra information. Here is an example:
QUESTION
So I have program written in a python file (main.py) that uses classes in an api wrapper file (bluerev.py). I want to use the loguru logger in main.py to collect all exceptions from the program + all requests made in the api wrapper. So the logging set up in the bluerev.py api wrapper looks like this:
...ANSWER
Answered 2022-Jan-07 at 10:59The problem is that loguru uses a completely different mechanism for logging than the classic logging library. The classic logging library constructs a hierarchy of loggers, and log records are propagate up to the root (see the Advanced logging tutorial from the Python docs for reference). But loguru does not use at all this hierarchy, it operates in a totally disjointed way from it.
So if you want the logs emitted using the classic logging library to be ultimately handled by loguru, you have to intercept them.
Here is a Minimal Reproducible Example of my solution :

Answered 2021-Dec-18 at 10:36For reasons I don't yet understand, Cheetah does not follow normal conventions to access object instance attributes and methods.

ANSWER
Answered 2021-Nov-25 at 09:31You're getting the behavior you're asking for. You've configured apscheduler to run check_list_len every five seconds, but you've also made it so that function runs without terminating - just sleeping for five seconds in an endless loop. That function never terminates, so apscheduler doesn't run it again - since it still hasn't finished.
Remove the infinite loop inside your utility function when using apscheduler - it'll call the function every five seconds for you:

Install loguru
You can use loguru 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.
