CNA-VGAP-004: The Linux evdev controller-mapping reader is tested only on hand-written entries in CI; the real-database test always skips

CNA snapshot 009d40f5  ·  Known Issues › Verification gaps  ·  source links pinned to 009d40f5

LinuxEvdevMapping.EveryEntryOfADatabaseFileIsRead skips unless CNA_TEST_GAMECONTROLLERDB names a file, no workflow sets it, and mapped-pad behaviour with physical generic HID pads has no recorded evidence.

Verified against

CNA 009d40f5 (009d40f5dd085c4e674d3479675fac84b12b3e0a)

Evidence basis

Source-verified: read at TARGET, not executed

Tests touching this area

Yes: see Current tests

Affected contract

CNA_GAMECONTROLLERCONFIG_FILE / CNA_GAMECONTROLLERCONFIG on the X11 and Wayland evdev gamepad hub

Expected behaviour

The community gamecontrollerdb format the backend accepts is exercised against a real database in CI.

Actual behaviour at TARGET

LinuxEvdevMappingTests.cpp reads CNA_TEST_GAMECONTROLLERDB and calls GTEST_SKIP when it is unset; no workflow sets it. EvdevMapping.cpp (ControllerMappingDatabase::FromEnvironment) is otherwise exercised on hand-written entries.

Source locations

• modules/platform/tests/CNA/Platform/LinuxEvdevMappingTests.cpp — EveryEntryOfADatabaseFileIsRead and its skip
• modules/platform/src/Linux/EvdevMapping.cpp — ControllerMappingDatabase::FromEnvironment

Evidence

Checked by reading at 009d40f5; not executed.

Focused reproduction

No focused reproduction is known. Nothing has been invented here; the evidence above is what exists.

Current tests

Hand-written mapping entries; the real-database test skips in CI.

Regression test

Vendor or download a pinned gamecontrollerdb.txt in CI and set CNA_TEST_GAMECONTROLLERDB.

Blast radius

Generic HID pads on the native X11 and Wayland platforms.

Workaround

No workaround is known.
