From 434cb7587e8a01d0650b311bb2a986817ee53045 Mon Sep 17 00:00:00 2001 From: Krzysztof kuhy Rudnicki Date: Sat, 22 Aug 2026 17:10:15 +0200 Subject: [PATCH] Test bt_adapter.sh to 98.55%; line 97 is unreachable by construction Third of the 16 untested fixes/lib libs, and the first that does NOT come off the allowlist. 68/69 = 98.55%, up from 45/69. The remaining line is not a missing test: PS4='+TRACE:${BASH_SOURCE##*/}:${LINENO} ' bash -x shows bash attributing the whole multi-line dbus-send assignment in _services_resolved to line 100, and never emitting line 97 at all. Line 97 is the OPENING line of a backslash-continued statement; kcov instruments it, bash never attributes a statement to it. That is defect (a) in docs/kcov-under-report.md -- a wrong denominator -- and no test can move it. continuation_lines() in shell_coverage_lines.py already excludes such lines, but only detects them by tracking QUOTE state, so a line ending in an unquoted backslash slips through. Fixing that is deliberately left out of this commit: it changes the denominator for every measured lib, and if it regresses one of the libs now gated with no exemption, reverting a mixed commit would throw away these tests too. Scope of the problem, measured rather than guessed -- backslash continuations are confined to the bluetooth family: bt_audio.sh 10, bt_adapter.sh 7, bt_pairing.sh 3, pacman_hook_stall_summary.sh 2, and ZERO in the other 12 remaining libs. So this caps bt_audio.sh next and then stops mattering. Also replaces the harness's _t_only_path with _t_hide. _t_only_path dropped PATH to $FAKE_BIN alone, which hid grep, head and sort as well as the tool under test -- so the "usbreset is not installed" case died in a cascade of "command not found" and passed for the wrong reason instead of exercising the fallback. _t_hide rebuilds PATH from symlinks to every real executable except the named ones; verified directly that command -v usbreset is then empty while grep and head still resolve. bt_report.sh (37/37) and bt_pairing.sh (65/65) re-measured at --min 100, both exit 0, so neither cleared lib regressed.
