Torjus Håkestad	a065eab759	fix: improve error messages for flake metadata command Capture stderr from nix flake metadata to show the actual error message instead of just "exit status 1". Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-06 23:21:52 +01:00
Torjus Håkestad	883ec25a62	fix: add nix and git to PATH for flake collector The systemd service runs in a sandboxed environment without the usual PATH. Add nix and git to the service path when flake collector is enabled so it can run `nix flake metadata` on git+https:// URLs.

Torjus Håkestad	858e047bff	fix: add timeouts to prevent denial of service Add 30-second timeout to nix flake metadata command to prevent hanging on slow or unresponsive remotes. Add HTTP server timeouts (read, write, idle) to protect against slowloris-style attacks. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-02-06 22:58:05 +01:00
