# This script is intended to be used by binary_search_state.py. It is to |
|
# be used for testing/development of the binary search triage tool |
|
# itself. It waits for the test setup script to build and install the |
|
# image, then checks the hashes in the provided file. |
|
# If the real hashes match the checksum hashes, then the image is 'good', |
|
# otherwise it is 'bad'. This allows the rest of the bisecting tool |
|
# to run without requiring help from the user (as it would if we were |
|
# dealing with a real 'bad' image). |
|
# |
|
|
|
# |
|
# Initialize the value below before using this script!!! |
|
# |
|
# Make an md5sum of all the files you want to check. For example if you want |
|
# file1, file2, and file3 to be found as bad items: |
|
# |
|
# md5sum file1 file2 file3 > checksum.out |
|
# |
|
# (Make sure you are hashing the files from your good build and that the hashes |
|
# from good to bad build differ) |
|
# |
|
# Then set HASHES_FILE to be the path to 'checksum.out' |
|
# In this example, file1, file2, file3 will be found as the bad files |
|
# because their hashes won't match when from the bad build tree. This is |
|
# assuming that the hashes between good/bad builds change. It is suggested to |
|
# build good and bad builds at different optimization levels to help ensure |
|
# each item has a different hash. |
|

|
# WARNING: |
|
# Make sure paths to all files are absolute paths or relative to |
|
# binary_search_state.py |

# cros_pkg bisector example: |
|
# 1. Build good packages with -O1, bad packages with -O2 |
|
# 2. cros_pkg/switch_to_good.sh pkg1 pkg2 pkg3 |
|
# 3. md5sum pkg1 pkg2 pkg3 > checksum.out.cros_pkg |
|
# 4. Set HASHES_FILE to be checksum.out.cros_pkg |
|
# 5. Run the bisector with this test script |
