Peracotta

🍐 P.E.R.A.C.O.T.T.A. 🍐

Progetto Esteso Raccolta Automatica Configurazioni hardware Organizzate Tramite Tarallo Autonomamente

Program to gather data, display it and update T.A.R.A.L.L.O. automatically.

Common usage

Multiple use cases are possible. More details on each program are provided in the How to install and run section.

You are using a relatively fast pc

Launch peracotta: that is the GUI that allows you to gather data, parse it and display it.

Main peracotta window, displaying a motherboard

Options can be configured in the left pane, then after Generate is pressed data is displayed in the right pane. Some basic editing is possible (add and remove items and features, edit feature values). The result can be saved as a JSON or uploaded directly to tarallo.

You are using a slow pc or you don't have PyQt installed

Launch peracruda from the terminal: this a script that gathers and parses data, however it offers no editing capabilities. At the end, you can save data as a JSON or upload it to tarallo directly.

The saved JSON can be uploaded to tarallo or imported from the peracotta GUI e.g. on another computer, to review and edit it before upload.

You are on a pc that barely runs

If you are desperate and the entire system is unstable due to failing hardware or any other reason, run scripts/generate_files.sh. That's the most bare-bones way to gather data: the script takes a single (optional) parameter for the output directory, and generates some txt files. No parsing is done.

You can load those files in peracruda (-f option) or peracotta (File > Load raw files option) and continue from there.

How to install and run

sudo apt install libxcb-cursor-dev
pip install peracotta

Privileges and sudo

generate_files.sh requires root permissions. There are a few ways around this, none of which is terribly secure:

Call the script through sudo

This is what is done automatically: both peracruda and peracotta will run sudo generate_files.sh where needed.

peracotta will also ask you the sudo password, however keep in mind that is done with a QMessageBox and the password is stored in memory in plaintext. If you don't trust our code, don't type it there.

If you have configured sudo with NOPASSWD, at least for the generate_files.sh script, you can add this to .env:

export GENERATE_FILES_ASK_SUDO_PASSWORD=0

so it will not ask your password anymore but still use sudo.

Run the script as root

This is not recommended, but you can run everything as root and disable sudo. This is particularly useful if you don not have sudo at all.

Add this to your .env:

export GENERATE_FILES_USE_SUDO=0

Manually

Run sudo generate_files.sh /path/to/output/directory then load the raw files in peracruda or peracotta. This is probably the safest way, considering that generate_files.sh is pretty short so you can inspect it before running. Everything else will work as usual and won't require root permissions.

How to develop

Same as before, until the pip install part. Just install requirements-dev.txt instead: pip install -r requirements-dev.txt

This will allow you to run tests: pytest -vv tests

Some markers are also available, e.g. you can run pytest -m gui to just test the gui, or pytest -m 'not gui' to test everything else. See pytest.ini for a list of markers.

If requirements change:

If you can't run generate_files.sh because you don't have access to sudo, such as on our development VM, you can look at tests/source_files for examples.

peracruda (CLI)

This script basically runs sudo ./generate_files.sh and collect data into an appropriate json for T.A.R.A.L.L.O, but it does so in an interactive manner, so you can either pass it the arguments, or it will ask you for them nicely.

You can also pass as the -f/--files argument the directory where generate_files.sh dropped its files.

You can find the usage below, but keep in mind that the three most important arguments are:

usage: peracruda [-h] [-f] [--code CODE] [--owner OWNER] [-p PARSERS]
                 [-g | -c | -b | --gpu-none] [-v]
                 [path]
Parse the files generated with generate_files.sh and get all the possible info
out of them
positional arguments:
  path                  optional path where generated files are stored
options:
  -h, --help            show this help message and exit
  -f, --files           reuse previously generated files
  --code CODE           set the code assigned by T.A.R.A.L.L.O
  --owner OWNER         set a owner
  -p PARSERS, --parsers PARSERS
                        which parsers to use
  -v, --verbose         print some warning messages
GPU Location:
  -g, --gpu             computer has dedicated GPU
  -c, --cpu             GPU is integrated inside the CPU
  -b, --motherboard     GPU is integrated inside the motherboard
  --gpu-none            There's no GPU at all

peracotta (GUI)

Just need to run it with ./peracotta or from your file manager. It does everything the terminal based version does and more, all through a GUI.

generate_files.sh

This will create some txt files with data related to the computer, that will be parsed by launching peracruda with -f/--files argument. The hard work is powered by the many read_X.py scripts, which are the actual parsers.

Install dependencies on Debian-based distributions (Debian, Ubuntu, Xubuntu, etc): sudo apt install pciutils i2c-tools mesa-utils smartmontools dmidecode These are the actual programs that generate the files that we parse.

parsers

There are many read_something.py scripts in the parsers directory: these are used internally by the other scripts. They can also be launched from the command line, with very basic parameters. They can also be imported as libraries.

This directory contains some images and other files used by the GUI.
