python: fix installed scripts

[ymorin-orange]

Changes:

• Bug fix:
  • Closes: python: incorrect scripts installed #255
  • Fix dependencies on IoT3 (due to unpublished packages)

How to test:

Pre-requisites:

• a python 3.11 environment; if you do not have one already, use a container:

  $ docker container run \
      --detach \
      --name iot3 \
      --rm \
      -ti \
      --network host \
      -e http_proxy \
     -e https_proxy \
     -e no_proxy \
      --user $(id -u):$(id -u) \
      --mount type=bind,source=$(pwd),destination=$(pwd) \
      --workdir $(pwd) \
      python:3.11.9-slim-bookworm \
      /bin/bash -il
  $ docker container exec -u 0:0 iot3 apt update
  $ docker container exec -u 0:0 iot3 apt install -y build-essential git
  $ docker container attach iot3

  Note: in the following the $ prompt means running in a shell that has access to python3.11, while the 🐍 $ prompt means running in the activated venv.

1. Install the its-interqueuemanager package:

   $ python3.11 -m venv /tmp/iqm
   $ . /tmp/iqm/bin/activate
   🐍 $ pip install python/its-interqueuemanager
   🐍 $ /tmp/iqm/bin/its-iqm -h
   🐍 $ deactivate

2. Install the its-status package:

   $ python3.11 -m venv /tmp/status
   $ . /tmp/status/bin/activate
   🐍 $ pip install python/its-status
   🐍 $ /tmp/status/bin/its-status -h
   🐍 $ deactivate

3. Install the its-vehicle package (note: due to unpublished python packages, we need to resolve dependencies by hand for now):

   $ python3.11 -m venv /tmp/vehicle
   $ . /tmp/vehicle/bin/activate
   🐍 $ pip install linuxfd==1.5 python/iot3
   🐍 $ pip install --no-deps python/its-vehicle
   🐍 $ /tmp/vehicle/bin/its-vehicle -h
   🐍 $ deactivate

---

Expected results:

1. The its-interqueuemanager package installs a script named its-iqm; its-iqm -h displays help for its-iqm.
2. The its-status package installs a script named its-status; its-status -h displays help for its-status.
3. The its-vehicle package installs a script named its-status; its-vehicle -h displays help for its-vehicle.

@ymorin-orange I've been following the full procedure - using a container -, but I am running into the following error after running 🐍 $ pip install python/its-interqueuemanager:

Processing ./python/its-interqueuemanager
  Installing build dependencies ... done
  Getting requirements to build wheel ... error
  error: subprocess-exited-with-error
  
  × Getting requirements to build wheel did not run successfully.

      error: could not create 'its_iqm.egg-info': Permission denied
      [end of output]

Should the container be started with sudo to get the necessary rights?

This is due to a discrepancy between using a "normal" Docker installation vs. Docker Desktop.

After fixing docker configuration issues on the test machine (should use docker.io and not docker desktop):

Test 1

its-interqueuemanager package install successful.
Command /tmp/iqm/bin/its-iqm -h shows:

usage: its-iqm [-h] [--config CONFIG] [--debug]

options:
  -h, --help            show this help message and exit
  --config CONFIG, -c CONFIG
                        Path to the configuration file (default: /etc/its/iqm.cfg)
  --debug               Print tons of debug messages on stderr

Test 2

its-status package install successful.
Command /tmp/status/bin/its-status -h shows:

usage: its-status [-h] [--config CONFIG]

options:
  -h, --help            show this help message and exit
  --config CONFIG, -c CONFIG
                        Path to the configuration file (default: /etc/its-status/its-status.cfg)

Test 3

its-vehicle package install successful.
Command /tmp/vehicle/bin/its-vehicle -h shows:

usage: its-vehicle [-h] [--config CONFIG] [--debug]

options:
  -h, --help            show this help message and exit
  --config CONFIG, -c CONFIG
                        Path to the configuration file (default: /etc/its/vehicle.cfg)
  --debug, -d           Enable debug messages
