The earlier commit in 2dfc1a3898
unintentionally changed the behavior. It gives a different result when
looking up non-existent mount points (e.g. /cache on marlin).
The logic behind volume_for_path("/xyz") is unclear:
- It's fine to return non-null value if it's called by
ensure_path_mounted() before accessing that file "/xyz". (Just based
on the function name, we're not actually having this case.)
- It should return nullptr if the caller is interested in the existence
of that particular mount point "/xyz".
This CL renames the function to volume_for_mount_point(), which does an
exact match by querying the given mount point from libfs_mgr. The former
volume_for_path() has been moved down to function scope for serving
ensure_path_mounted() only.
Test: Build and boot into recovery on bullhead and marlin respectively.
'View recovery logs'.
Test: 'Mount /system'
Test: 'Apply update from ADB'

The Recovery Image
Quick turn-around testing
mm -j && m ramdisk-nodeps && m recoveryimage-nodeps
# To boot into the new recovery image
# without flashing the recovery partition:
adb reboot bootloader
fastboot boot $ANDROID_PRODUCT_OUT/recovery.img
Running the tests
# After setting up environment and lunch.
mmma -j bootable/recovery
# Running the tests on device.
adb root
adb sync data
# 32-bit device
adb shell /data/nativetest/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest/recovery_component_test/recovery_component_test
# Or 64-bit device
adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest64/recovery_component_test/recovery_component_test
Running the manual tests
recovery-refresh and recovery-persist executables exist only on systems without
/cache partition. And we need to follow special steps to run tests for them.
-
Execute the test on an A/B device first. The test should fail but it will log some contents to pmsg.
-
Reboot the device immediately and run the test again. The test should save the contents of pmsg buffer into /data/misc/recovery/inject.txt. Test will pass if this file has expected contents.
ResourceTest validates whether the png files are qualified as background text
image under recovery.
1. `adb sync data` to make sure the test-dir has the images to test.
2. The test will automatically pickup and verify all `_text.png` files in
the test dir.
