Command line program to process log file and return the most active cookie

• Cookie log file format - csv
• Define the most active cookie as one seen in the log the most times during a given day

Assumptions:

• If multiple cookies meet criteria, return all of them on separate lines
• -d parameter takes date in UTC time zone
• You have enough memory to store the contents of the whole file
• Cookies in the log file are sorted by timestamp (most recent occurrence is first line of the file)

Clone Repository:

$ git clone https://github.com/aamijar/most-active-cookie.git

Quick Run:

$ python3 most_active_cookie.py cookie_log.csv -d 2018-12-09

Executable and Run:

$ chmod +x most_active_cookie
$ ./most_active_cookie cookie_log.csv -d 2018-12-09

Python3 + Pytest

Virtual Environment [Optional]:

Ex: Miniconda

$ conda create -n cookie python
$ conda activate cookie

Install Pytest via pip:

$ pip install pytest

Save environment:

$ conda env export > environment.yml

$ pip freeze > requirements.txt

At root of project use pytest

$ python3 -m pytest

• /cookie - datatypes to hold cookie[s] and find most active
• /parsing
  • read cli arguments and read log file lines
  • filter log file content based on cli arguments (ex. UTC Date) using binary search
• /timeutil - helper functions to determine date and time from UTC format
• /testing - pytest based tests to validate program functions
