The csuite.py script does not work correctly on Windows. It runs
correctly in baseline mode, but there are two problems when running in
compare mode:
1. In compare mode the output of benchmark.py is piped to the
compare-baseline.py script, but Windows only execute python files if
python.exe is the default program to open '.py' files, and this is
not the case, by default, when python is installed as part of the
depot_tools.
Fix: explicitly add the 'python' command before compare-baseline.py.
2. By default CSuite prints the results to stdout using escapes codes
that add color highlights. But this does not work on Windows when
compare-baseline.py is launched with a pipe:
python test/benchmarks/csuite/benchmark.py <...> |
python test/benchmarks/csuite/compare-baseline.py <baseline_results>
Fix: Do not use a pipe. Write the benchmark numbers for the
compare-run into a separate file, and pass the path to this file to
compare-baseline.py
