Overrides: object.__init__

_FindNextOpcode(job, timeout_strategy_factory)
Static Method

source code 

Locates the next opcode to run.

Parameters:
  • job (_QueuedJob) - Job object
  • timeout_strategy_factory - Callable to create new timeout strategy

_MarkWaitlock(job, op)
Static Method

source code 

Marks an opcode as waiting for locks.

The job's start timestamp is also set if necessary.

Parameters:

_CheckDependencies(queue, job, opctx)
Static Method

source code 

Checks if an opcode has dependencies and if so, processes them.

Parameters:
Returns: bool
Whether opcode will be re-scheduled by dependency tracker

__call__(self, _nextop_fn=None)
(Call operator)

source code 

Continues execution of a job.

Parameters:
  • _nextop_fn - Callback function for tests
