parser201 1.5.1

Extract individual fields from lines in Apache access logs

Features

The centerpiece of the parser201 module is the LogParser class. The class initializer takes a single line from an Apache access log file and extracts the individual fields into attributes within an object.

Installation

pip3 install parser201

Usage

The most common use-case for parser201 is importing individual lines from an Apache access log file and creating LogParser objects, like this:

from parser201 import LogParser

with open('access.log', 'r') as f:
    for line in f:
        lp = LogParser(line)
        # Use lp as desired: add to List, Dictionary, etc.

Version History

• 1.5.1 (2024-09-23)
  • Migrated packaging and build system to uv, and code formatting and linting to ruff.
  • Improved exception handling for invalid date-time objects.
  • Migrated documentation generation to pdoc.
  • Code and documentation linting.
    
    
• 1.5.0 (2024-01-27)
  • Cleaned up packaging for better PEP561 compliance.
  • Cleaned up type hints.
  • Dropped support for converting timestamps to local machine time. Processing local timezones across multiple architectures and operating systems is a bit of a hot mess in Python right now. There's just too much variability with regard to OS Settings, location, daylight savings time, etc. The performance of this feature was spotty at best. There is still support for the original timezone and converstion to UTC.
    
    
• 1.4.1 (2023-06-22)
  • Migrated code formatter to black.
    
    
• 1.4.0 (2023-04-30)
  • Strengthened regular expression parsing to handle log lines that contain a wider array of malicious attacks.

  • Implemented selectable formatting options for timestamp attribute {string, date_obj}.
  • Migrated API reference to GitHub pages.
  • Code cleanup.

  • Changed behavior to gracefully fail for any malformed input line. If an input line cannot be successfully parsed, all attributes of the returned object are set to None and no messages are printed.
  • Added additional pytest cases to verify failure behavior.
    
    
• 0.1.9 (2021-09-15)
  • Code cleanup for pep8 compliance.
  • Cleaned up Makefiles and scripts to remove references to python (meaning python2) and replace it with python3.
