From c25ee8158000770cb667b914de62f802467c204e Mon Sep 17 00:00:00 2001 From: Mihai Dinca <mdinca@suse.de> Date: Fri, 16 Nov 2018 17:05:29 +0100 Subject: [PATCH] Async batch implementation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add find_job checks Check if should close on all events Make batch_delay a request parameter Allow multiple event handlers Use config value for gather_job_timeout when not in payload Add async batch unittests Allow metadata to pass Pass metadata only to batch jobs Add the metadata to the start/done events Pass only metadata not all **kwargs Add separate batch presence_ping timeout Fix async batch race conditions Close batching when there is no next batch Add 'batch_presence_ping_timeout' and 'batch_presence_ping_gather_job_timeout' parameters for synchronous batching Fix async-batch multiple done events Fix memory leak produced by batch async find_jobs mechanism (bsc#1140912) Multiple fixes: - use different JIDs per find_job - fix bug in detection of find_job returns - fix timeout passed from request payload - better cleanup at the end of batching Co-authored-by: Pablo Suárez Hernández <psuarezhernandez@suse.com> Improve batch_async to release consumed memory (bsc#1140912) Use current IOLoop for the LocalClient instance of BatchAsync (bsc#1137642) Fix failing unit tests for batch async Remove unnecessary yield causing BadYieldError (bsc#1154620) Fixing StreamClosed issue Fix batch_async obsolete test batch_async: avoid using fnmatch to match event (#217) Batch Async: Catch exceptions and safety unregister and close instances Fix unit tests for batch async after refactor Changed imports to vendored Tornado Async batch implementation fix (#320) Remove deprecated usage of NO_MOCK and NO_MOCK_REASON --- salt/auth/__init__.py | 2 + salt/cli/batch.py | 109 ++++++-- salt/cli/batch_async.py | 315 +++++++++++++++++++++++ salt/client/__init__.py | 51 ++-- salt/master.py | 20 ++ salt/transport/ipc.py | 9 +- salt/utils/event.py | 8 +- tests/unit/cli/test_batch_async.py | 386 +++++++++++++++++++++++++++++ 8 files changed, 839 insertions(+), 61 deletions(-) create mode 100644 salt/cli/batch_async.py create mode 100644 tests/unit/cli/test_batch_async.py diff --git a/salt/auth/__init__.py b/salt/auth/__init__.py index 3b73c2ec08..6f300fe7c4 100644 --- a/salt/auth/__init__.py +++ b/salt/auth/__init__.py @@ -49,6 +49,8 @@ AUTH_INTERNAL_KEYWORDS = frozenset( "print_event", "raw", "yield_pub_data", + "batch", + "batch_delay", ] ) diff --git a/salt/cli/batch.py b/salt/cli/batch.py index 2a692e13f8..828a1ded5b 100644 --- a/salt/cli/batch.py +++ b/salt/cli/batch.py @@ -13,9 +13,88 @@ import salt.exceptions import salt.output import salt.utils.stringutils +# pylint: disable=import-error,no-name-in-module,redefined-builtin + log = logging.getLogger(__name__) +def get_bnum(opts, minions, quiet): + """ + Return the active number of minions to maintain + """ + partition = lambda x: float(x) / 100.0 * len(minions) + try: + if isinstance(opts["batch"], str) and "%" in opts["batch"]: + res = partition(float(opts["batch"].strip("%"))) + if res < 1: + return int(math.ceil(res)) + else: + return int(res) + else: + return int(opts["batch"]) + except ValueError: + if not quiet: + salt.utils.stringutils.print_cli( + "Invalid batch data sent: {}\nData must be in the " + "form of %10, 10% or 3".format(opts["batch"]) + ) + + +def batch_get_opts( + tgt, fun, batch, parent_opts, arg=(), tgt_type="glob", ret="", kwarg=None, **kwargs +): + # We need to re-import salt.utils.args here + # even though it has already been imported. + # when cmd_batch is called via the NetAPI + # the module is unavailable. + import salt.utils.args + + arg = salt.utils.args.condition_input(arg, kwarg) + opts = { + "tgt": tgt, + "fun": fun, + "arg": arg, + "tgt_type": tgt_type, + "ret": ret, + "batch": batch, + "failhard": kwargs.get("failhard", parent_opts.get("failhard", False)), + "raw": kwargs.get("raw", False), + } + + if "timeout" in kwargs: + opts["timeout"] = kwargs["timeout"] + if "gather_job_timeout" in kwargs: + opts["gather_job_timeout"] = kwargs["gather_job_timeout"] + if "batch_wait" in kwargs: + opts["batch_wait"] = int(kwargs["batch_wait"]) + + for key, val in parent_opts.items(): + if key not in opts: + opts[key] = val + + opts["batch_presence_ping_timeout"] = kwargs.get( + "batch_presence_ping_timeout", opts["timeout"] + ) + opts["batch_presence_ping_gather_job_timeout"] = kwargs.get( + "batch_presence_ping_gather_job_timeout", opts["gather_job_timeout"] + ) + + return opts + + +def batch_get_eauth(kwargs): + eauth = {} + if "eauth" in kwargs: + eauth["eauth"] = kwargs.pop("eauth") + if "username" in kwargs: + eauth["username"] = kwargs.pop("username") + if "password" in kwargs: + eauth["password"] = kwargs.pop("password") + if "token" in kwargs: + eauth["token"] = kwargs.pop("token") + return eauth + + class Batch: """ Manage the execution of batch runs @@ -39,6 +118,7 @@ class Batch: self.pub_kwargs = eauth if eauth else {} self.quiet = quiet self.options = _parser + self.minions = set() # Passing listen True to local client will prevent it from purging # cahced events while iterating over the batches. self.local = salt.client.get_local_client(opts["conf_file"], listen=True) @@ -51,7 +131,7 @@ class Batch: self.opts["tgt"], "test.ping", [], -
