ctimed-rotating-file-handler 0.1.2

TimedRotatingFileHandler using ctime instead of mtime to determine rollover times.

CTimedRotatingFileHandler

TimedRotatingFileHandler using ctime instead of mtime to determine rollover times.

This module provides a subclass CTimedRotatingFileHandler of logging.handlers.TimedRotatingFileHandler that uses file creation time instead of file modification time to calculate the next rollover time.

It also contains a workaround for "file system tunneling" on Windows, which prevents new files from having new creation times if they have already existed a short time ago.
To be able to do this, a new dependency to win32-setctime is introduced (only needed if running on Windows).

Usage Example

import logging
from ctimed_rotating_file_handler import CTimedRotatingFileHandler

logfile = 'path/to/logdir/MyName.log'
loglevel=logging.DEBUG
backupcount = 7
logformat='%(asctime)s\t%(levelname)s\t%(name)s\t%(message)s'

log = logging.getLogger()
formatter = logging.Formatter(fmt=logformat)
loghandler = CTimedRotatingFileHandler(logfile, when='midnight', interval=1, backupCount=backupcount)
loghandler.setFormatter(formatter)
logging.root.addHandler(loghandler)
logging.root.setLevel(loglevel)

log.info('This is an information.')

Development and building

Prerequesites

• Python 3.9 has to be installed with pip and packages:
  • virtualenv
  • build

Setup development environment

After cloning the repo, you should create a virtual environment for all further development work.
This may be done by calling one of the included setup_venv scripts for your platform:

• setup_venv.cmd: Windows batch
• setup_venv.ps1: Windows Powershell
• setup_venv.sh: Bash

This will

• create a new virtual environment in the directory venv or update an existing one,
• install all requirements from requirements.txt.

You still have to activate the venv manually (or automatically by configuring it in your IDE).

Building the package

All buils settings are inside pyproject.toml.
You might want to change project.version before building (eg. add .dev1 to it), so you always know which one you are dealing with.

To build the project, simply run this command from inside the project directory (the same directory that contains pyproject.toml):

python -m build

This will create .whl and .tar.gz in the directory dist.
