Subject: [PATCH v3 0/8] Run tests in parallel
Date: Mon, 12 Feb 2024 10:58:50 -0800 [thread overview]
Message-ID: <20240212185858.68189-1-irogers@google.com> (raw)
If command line option '-p' is provided, start/fork all tests in the
main thread and then gather them in order at the end. On a laptop test
time was reduced from 5 minutes 21 seconds to 1 minute 50 seconds. The
option isn't default as the test shows up perf and test flakes.
The '-v' option is modified so that 'perf test -v' will give verbose
output only from failing tests.
v3 - fix a crash if shell test directory isn't found, remove merged patch.
v2 - fix parallel test output/verbose issue
v1 - initial PoC
Ian Rogers (8):
perf thread_map: Skip exited threads when scanning /proc
perf list: Add scandirat compatibility function
perf tests: Avoid fork in perf_has_symbol test
tools subcmd: Add a no exec function call option
perf test: Rename builtin-test-list and add missed header guard
perf tests: Use scandirat for shell script finding
perf tests: Run time generate shell test suites
perf tests: Add option to run tests in parallel
