This file explains how to set up and run the various kinds of bisection tests.
|
|
The bisection tool comes with several sets of tests which you should
|
run after updating any of the bisection tool scripts OR after updating
|
the Android compiler wrapper (to make sure the wrapper will still work
|
correctly with bisection).
|
|
Before you start.
|
----------------
|
|
Before you can run the tests, your PYTHONPATH environment variable
|
must be correct. This means that it must include both the
|
toolchain-utils directory and the binary_search_tool directory. The
|
easiest way to set it is:
|
|
$ cd toolchain-utils
|
$ export PYTHONPATH=`pwd`:${PYTHONPATH}
|
$ cd binary_search_tool
|
$ export PYTHONPATH=`pwd`:${PYTHONPATH}
|
|
|
Running the unittests.
|
----------------------
|
|
To run the basic unit tests:
|
|
$ cd toolchain-utils/binary_search_tool/test
|
$ ./binary_search_tool_tester.py
|
|
Running the bisection tests, testing the compiler wrapper.
|
----------------------------------------------------------
|
|
If you want to run the bisection tests, and test the compiler wrapper
|
(to make sure the POPULATE_GOOD and POPULATE_BAD stages are still
|
working properly) you can do the following.
|
|
If you are testing with the ANDROID COMPILER WRAPPER, you need to to some
|
preliminary setup:
|
|
Set up the compiler wrapper to replace GCC:
|
|
$ cd <android-root/prebuilts/clang/host/linux-x86/clang-368880/bin
|
$ cp clang gcc
|
$ whereis gcc
|
gcc: /usr/bin/gcc /usr/lib/gcc /usr/bin/X11/gcc /usr/share/man/man1/gcc.1.gz
|
$ cd /usr/bin
|
$ ls -l gcc
|
lrwxrwxrwx 1 root root 7 Feb 3 17:00 gcc -> gcc-4.8*
|
$ sudo mv gcc gcc.real
|
$ sudo ln -s <android-root>/prebuilts/clang/host/linux-x86/clang-3688880/bin/gcc gcc
|
|
Move to the correct directory, then run the test script:
|
|
$ cd toolchain-utils/binary_search_tool
|
$ ./run_bisect_test.py
|
|
|
If you are testing with the CHROMEOS COMPILER WRAPPER, you MUST run the
|
tests from INSIDE your CHROOT (but you don't need to do any special setup):
|
|
$ cd <path-to-chromeos-root>
|
$ cros_sdk
|
$ cd ~/trunk/src/third_party/toolchain-utils
|
|
Set up your PYTHONPATH:
|
|
$ export PYTHONPATH=`pwd`:${PYTHONPATH}
|
$ cd binary_search_tool
|
$ export PYTHONPATH=`pwd`:${PYTHONPATH}
|
|
Run the test script:
|
|
$ ./run_bisect_test.py
|
|
|
Running the bisection tests, without testing the compiler wrapper.
|
------------------------------------------------------------------
|
|
$ cd toolchain-utils/binary_search_tool
|
$ ./full_bisect_test/run-test-nowrapper.sh
|
