This directory contains modules related to tools for bisecting regressions. There are several different tools for bisecting regressions; the main use of these tools is to find revisions where a performance regression occurred. These tools are generally run by trybots but can also be run locally. Documentation: http://www.chromium.org/developers/bisecting-bugs http://www.chromium.org/developers/tree-sheriffs/perf-sheriffs/bisecting-performance-regressions Overview of bisect-related files in src/tools: run-bisect-perf-regression.py -- the script used to kick off a normal performance regression bisect job. run-bisect-perf-regression.cfg -- this file contains parameters for a bisect job, and is read by other modules including run-bisect-perf-regresion.py. run-bisect-manual-test.py -- a script which is used to manually bisect regressions; this also depends on bisect-perf-gression.py. bisect-perf-regression.py -- the main module which the others depend on. bisect-manual-test.py -- a helper module used when manually bisect regressions.
