updater: Clean up LoadSrcTgtVersion2().

Rename to LoadSourceBlocks() by moving the target blocks parsing part
into the caller. This allows detecting whether the target blocks have
already had the expected data before loading the source blocks. It
doesn't affect anything when applying an update package for the first
time, but it skips loading the unneeded source blocks when resuming an
update. It additionally avoids unnecessarily dumping the "corrupt"
source/stash blocks when resuming an update.

Bug: 33694730
Test: Apply an incremental update with the new updater.
Test: Resume an incremental update with the new updater.

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.
