Tests that affect the repo in stateful ways are easier to write if we can run setup steps outside of the measured portion of perf iteration. This change adds a "--setup 'setup-script'" parameter to test_perf. To make invocations easier to understand, I also moved the prerequisites to a new --prereq parameter. The setup facility will be used in the upcoming perf tests for batch mode, but it already helps in some existing tests, like t5302 and t7820.

Set GIT_PERF_7820_GREP_OPTS in the environment to pass options to
|
|
git-grep. Make sure to include a leading space,
|
|
e.g. GIT_PERF_7820_GREP_OPTS=' -i'. Some options to try:
|
|
|
|
-i
|
|
-w
|
|
-v
|
|
-vi
|
|
-vw
|
|
-viw
|
|
|
|
If GIT_PERF_GREP_THREADS is set to a list of threads (e.g. '1 4 8'
|
|
etc.) we will test the patterns under those numbers of threads.
