The Swarming bot doesn't.\r\n\r\nHow to fix?\r\n- For any process that starts children processes, make sure all children\r\n processes terminated properly before each parent process exits. This is\r\n especially important in very deep process trees.\r\n - This must be done properly both in normal successful task and in case of\r\n task failure. Cleanup is very important.\r\n- The Swarming bot sends a SIGTERM in case of timeout.\r\n - You have 30.0 seconds to comply after the signal was sent to the process\r\n before the process is forcibly killed.\r\n- To achieve not leaking children processes in case of signals on timeout, you\r\n MUST handle signals in each executable / python script and propagate them to\r\n children processes.\r\n - When your test script (python or binary) receives a signal like SIGTERM or\r\n CTRL_BREAK_EVENT on Windows), send it to all children processes and wait for\r\n them to terminate before quitting.\r\n\r\nSee\r\nhttps://chromium.googlesource.com/infra/luci/luci-py.git/+/master/appengine/swarming/doc/Bot.md#Graceful-termination_aka-the-SIGTERM-and-SIGKILL-dance\r\nfor more information.\r\n\r\n*** May the SIGKILL force be with you ***\r\n" ], "outputs_ref": { "isolated": "35669f853ce8d4eae274edab623641713ead99c6", "isolatedserver": "https://isolateserver.appspot.com", "namespace": "default-gzip", "view_url": "https://isolateserver.appspot.com/browse?namespace=default-gzip&hash=35669f853ce8d4eae274edab623641713ead99c6" }, "properties_hash": null, "run_id": "403303e03c6f4911", "server_versions": [ "3793-c7dcd56" ], "started_ts": "2018-09-27T08:54:06.369950", "state": 112, "tags": [ "build_is_experimental:false", "buildername:dart2js-strong-win-x64-firefox-dev", "buildnumber:8", "cpu:x86-64", "data:fac819c467cb67c3f5c1620e402af8765aeb93d0", "master:client.dart", "name:dart2js", "os:Windows", "pool:dart.tests", "priority:25", "service_account:none", "slavename:win10-dart-fedce810-us-central1-c-bxnn", "spec_name:dart.ci.sandbox:dart2js-strong-win-x64-firefox-dev", "stepname:dart2js co19_2 tests_shard_1 on Windows", "swarming.pool.template:none", "swarming.pool.version:378bf44637390f3eca3a8bcb5d9624a4373dc8c6", "user:None" ], "try_number": 1, "user": "" } ] }
