Krzysztof kuhy Rudnicki 779ace0c87 fix(hosts-guard): stop setup aborting silently, so the guards actually enable 
setup_hosts_guard.sh died partway on every run under `set -euo pipefail`,
which is why hosts-guard.path / hosts-bind-mount.service / nsswitch-guard.path
sat installed-but-disabled since 2026-02-02 and resolved-guard.path was never
installed at all — /etc/hosts had no watcher to restore it if tampered.

Two aborts, both silent:

1. `local_dot=$(grep -E '^\s*DNSOverTLS\s*=' ... | tail -1 | sed ...)` — grep
   exits 1 when the key is absent, pipefail propagates, the assignment returns
   1, set -e kills the script. DNSOverTLS is absent from a default
   resolved.conf, so this fired on EVERY run, right before resolved-guard.path
   was enabled. The fix-if-missing branch below it was unreachable because
   detecting "missing" aborted first. Same trap on the ReadEtcHosts probe.
   check_and_enable_services.sh already guarded its copy with `|| true`.

2. `systemctl restart systemd-resolved` — resolved is MASKED here (dnsmasq
   serves DNS), so the restart failed and aborted the script on its last step,
   after everything was already configured. Now skipped with a note.

Before: exit 1, resolved-guard disabled, nsswitch-guard start-limit-hit.
After: exit 0; hosts-guard.path, hosts-bind-mount.service, nsswitch-guard.path
and resolved-guard.path all enabled+active. DNS still resolves; getent ahosts
on doubleclick/googlesyndication/facebook returns 0.0.0.0; /etc/hosts still
immutable at 176888 lines.

README.md

testsAndMisc

A collection of personal projects, scripts, and experiments — from a GPS-based phone focus tool to Linux/Arch automation, with CI, linting, and pre-commit hooks across the board.

Highlights

Phone Focus Mode

Location-based app restriction for rooted Android. Automatically disables non-whitelisted apps within 500 m of home using ADB + Magisk. Features Haversine distance calculation, hysteresis to prevent toggling, fail-safe unlock, and state persistence. Bash, Android ADB.

Linux Configuration

Automated Arch Linux setup: fresh-install scripts, i3 window manager config, LaTeX environment, and system tests. Includes documentation and test result logging.

Scripts

Utility scripts for development workflows — build file validation, secret detection, and custom makepkg helpers.

Repository Layout

Path Description
python_pkg/ Python packages (each maintained subpackage lives here)
linux_configuration/ Arch Linux setup, i3 config, system maintenance scripts
phone_focus_mode/ GPS-based Android focus enforcer
scripts/ Workspace-level helper scripts and pre-commit hooks
docs/ Reference docs and historical reports
third_party/ Vendored upstream skills/agents
meta/ Repo-wide tooling: pyproject.toml, requirements.txt, .pre-commit-config.yaml, run.sh, lint_python.sh, .fvmrc. Symlinked into the repo root so tools that auto-discover from root keep working.

Archived / unmaintained projects live in the sibling repository testsAndMisc-archive.

Tooling

  • Python linting: Ruff with all rules enabled (see meta/pyproject.toml)
  • Dependencies: pip install -r meta/requirements.txt (combined runtime + dev)
  • CI: GitHub Actions — lint, build, and test on push
  • Testing: pytest (Python), custom shell-based test harness for scripts
