q-logger-py

q-logger-py is a pure Python 3 logging library that use queues for handling log messages.

It is thread-based, which makes it faster than standard file logging.

Installation

pip install q-logger-py

Usage

first need to create a QueueHandler and a ThreadWorker (either ThreadStdoutWorker or ThreadRotateFileWorker).

Then, add the QueueHandler to your logger and start the ThreadWorker.

import logging
from q_logger_py import QueueHandler, ThreadStdoutWorker

queue_handler = QueueHandler()
thread_worker = ThreadStdoutWorker(queue_handler.log_queue)

logger = logging.getLogger(__name__)
logger.addHandler(queue_handler)
logger.setLevel(logging.DEBUG)

thread_worker.start()
logger.debug('This is a debug')
logger.info('This is a info')
logger.warning('This is a warning')
logger.error('This is an error')
thread_worker.end()

Features

• Thread-based: uses threads to handle log messages, which makes it faster than standard file logging.
• Queue-based: uses queues to store log messages, which ensures that no log messages are lost.

Custom Output

key features of q-logger-py is the ease of creating custom outputs.

By inheriting from the BaseThreadWorker class, you can define output method to handle records in any way you want.

from q_logger_py.worker.base_thread_worker import BaseThreadWorker

class ThreadFileWorker(BaseThreadWorker):
    def __init__(self, log_queue, filename):
        super().__init__(log_queue)
        self.file = open(filename, 'a')

    def output(self):
        log_output = self.format(self.record)
        # add custom output here
        # self.file.write(log_output + '\n')
        # self.file.flush()
        print(log_output)
