oeqa/context: Only set buffer mode for non-concurrent tests
Periodically we'd see: NOTE: core-image-sato-1.0-r0 do_testsdk: ====================================================================== NOTE: core-image-sato-1.0-r0 do_testsdk: ERROR: broken-runner NOTE: core-image-sato-1.0-r0 do_testsdk: ---------------------------------------------------------------------- NOTE: core-image-sato-1.0-r0 do_testsdk: testtools.testresult.real._StringException: Traceback (most recent call last): File "/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-mips/build/meta/lib/oeqa/core/utils/", line 122, in _run_test File "/usr/lib/python3.6/site-packages/subunit/", line 1194, in run protocol = TestProtocolServer(result, self._passthrough, self._forward) File "/usr/lib/python3.6/site-packages/subunit/", line 514, in __init__ stream = stream.buffer AttributeError: '_io.StringIO' object has no attribute 'buffer' which seems to occur if a result arrives before all the runner threads have started. The runner's result handling changes sys.stdout to a buffer temporarily which can be seen in other threads and it can sometimes fail. Since the tests are running in a separate process we don't need this buffer handling in the concurrent case so only set when not parallelising. The concurrent class handle setting buffer mode internally. Signed-off-by: Richard Purdie <>
