nv-driver-locator
=================
nv-driver-locator is a tool for internal usage, which purpose is to notify about new Nvidia driver releases. It's kernel supports and performs:
* Update retrieval from multiple sources (**channels** component).
* Notification through various ways (**notifiers** component).
* Driver info matching and aggregation via configurable set of attributes (**hasher** component).
* Persistence of collected data for keeping track on already seen drivers (**db** component).
## Requirements
* Python 3.4+
* `beautifulsoup4` package - required only when NvidiaDownloadsChannel is used. On recent Debian/Ubuntu you may install it like this: `apt-get install python3-bs4`. For other cases see [this](https://www.crummy.com/software/BeautifulSoup/bs4/doc/#installing-beautiful-soup).
## Overview
### Structure
All scripts may be used both as standalone application and importable module. For CLI synopsys invoke program with `--help` option.
* nv-driver-locator.py - main executable, intended to be run as cron job.
* mailer.py - module with email routines and minimalistic email client for test purposes.
* gfe\_get\_driver.py - GeForce Experience client library (and test util).
* get\_nvidia\_downloads.py - Nvidia downloads site parser (and test util).
### Operation
1. Cron job queries all configured channels.
2. Program aggregates responses by hashing their's values covered by `key_components`. `key_components` is a list of JSON paths (represented by list too) specified in config file.
3. Program queries DB if given hash has any match in database.
4. If no match found and we have new instance, then all notifiers are getting fired.
5. New record gets written into DB.
