Add a job function as a child job.

See toil.job.JobFunctionWrappingJob for a definition of a job function.

Parameters:: fn (Callable) – Job function to be run as a child job with *args and **kwargs as arguments to this function. See toil.job.JobFunctionWrappingJob for reserved keyword arguments used to specify resource requirements.

Return type:: None

static wrapFn(fn, *args, **kwargs)[source]¶

Makes a Job out of a function.

Convenience function for constructor of toil.job.FunctionWrappingJob.

Parameters:: fn – Function to be run with *args and **kwargs as arguments. See toil.job.JobFunctionWrappingJob for reserved keyword arguments used to specify resource requirements.
Returns:: The new function that wraps fn.
Return type:: FunctionWrappingJob

static wrapJobFn(fn, *args, **kwargs)[source]¶

Makes a Job out of a job function.

Convenience function for constructor of toil.job.JobFunctionWrappingJob.

Parameters:: fn – Job function to be run with *args and **kwargs as arguments. See toil.job.JobFunctionWrappingJob for reserved keyword arguments used to specify resource requirements.
Returns:: The new job function that wraps fn.
Return type:: JobFunctionWrappingJob

encapsulate(name=None)[source]¶

Parameters:: name (Optional[str]) – Human-readable name for the encapsulated job.
Returns:: an encapsulated version of this job.
Return type:: EncapsulatedJob

rv(*path)[source]¶

Create a promise (toil.job.Promise).

The “promise” representing a return value of the job’s run method, or, in case of a function-wrapping job, the wrapped function’s return value.

Parameters:: path ((Any)) – Optional path for selecting a component of the promised return value. If absent or empty, the entire return value will be used. Otherwise, the first element of the path is used to select an individual item of the return value. For that to work, the return value must be a list, dictionary or of any other type implementing the __getitem__() magic method. If the selected item is yet another composite value, the second element of the path can be used to select an item from it, and so on. For example, if the return value is [6,{‘a’:42}], .rv(0) would select 6 , rv(1) would select {‘a’:3} while rv(1,’a’) would select 3. To select a slice from a return value that is slicable, e.g. tuple or list, the path element should be a slice object. For example, assuming that the return value is [6, 7, 8, 9] then .rv(slice(1, 3)) would select [7, 8]. Note that slicing really only makes sense at the end of path.
Returns:: A promise representing the return value of this jobs toil.job.Job.run() method.
Return type:: Promise

registerPromise(path)[source]¶

prepareForPromiseRegistration(jobStore)[source]¶

Set up to allow this job’s promises to register themselves.

Prepare this job (the promisor) so that its promises can register themselves with it, when the jobs they are promised to (promisees) are serialized.

The promissee holds the reference to the promise (usually as part of the job arguments) and when it is being pickled, so will the promises it refers to. Pickling a promise triggers it to be registered with the promissor.

Parameters:: jobStore (toil.jobStores.abstractJobStore.AbstractJobStore)
Return type:: None

checkJobGraphForDeadlocks()[source]¶

Ensures that a graph of Jobs (that hasn’t yet been saved to the JobStore) doesn’t contain any pathological relationships between jobs that would result in deadlocks if we tried to run the jobs.

See toil.job.Job.checkJobGraphConnected(), toil.job.Job.checkJobGraphAcyclic() and toil.job.Job.checkNewCheckpointsAreLeafVertices() for more info.

Raises:: toil.job.JobGraphDeadlockException – if the job graph is cyclic, contains multiple roots or contains checkpoint jobs that are not leaf vertices when defined (see toil.job.Job.checkNewCheckpointsAreLeaves()).

getRootJobs()[source]¶

Return the set of root job objects that contain this job.

A root job is a job with no predecessors (i.e. which are not children, follow-ons, or services).

Only deals with jobs created here, rather than loaded from the job store.

Return type:: Set[Job]

checkJobGraphConnected()[source]¶

Raises:: toil.job.JobGraphDeadlockException – if toil.job.Job.getRootJobs() does not contain exactly one root job.

As execution always starts from one root job, having multiple root jobs will cause a deadlock to occur.

Only deals with jobs created here, rather than loaded from the job store.

checkJobGraphAcylic()[source]¶

Raises:: toil.job.JobGraphDeadlockException – if the connected component of jobs containing this job contains any cycles of child/followOn dependencies in the augmented job graph (see below). Such cycles are not allowed in valid job graphs.

A follow-on edge (A, B) between two jobs A and B is equivalent to adding a child edge to B from (1) A, (2) from each child of A, and (3) from the successors of each child of A. We call each such edge an edge an “implied” edge. The augmented job graph is a job graph including all the implied edges.

For a job graph G = (V, E) the algorithm is O(|V|^2). It is O(|V| + |E|) for a graph with no follow-ons. The former follow-on case could be improved!

Only deals with jobs created here, rather than loaded from the job store.

checkNewCheckpointsAreLeafVertices()[source]¶

A checkpoint job is a job that is restarted if either it fails, or if any of its successors completely fails, exhausting their retries.

A job is a leaf it is has no successors.

A checkpoint job must be a leaf when initially added to the job graph. When its run method is invoked it can then create direct successors. This restriction is made to simplify implementation.

Only works on connected components of jobs not yet added to the JobStore.

Raises:: toil.job.JobGraphDeadlockException – if there exists a job being added to the graph for which checkpoint=True and which is not a leaf.
Return type:: None

defer(function, *args, **kwargs)[source]¶

Register a deferred function, i.e. a callable that will be invoked after the current attempt at running this job concludes. A job attempt is said to conclude when the job function (or the toil.job.Job.run() method for class-based jobs) returns, raises an exception or after the process running it terminates abnormally. A deferred function will be called on the node that attempted to run the job, even if a subsequent attempt is made on another node. A deferred function should be idempotent because it may be called multiple times on the same node or even in the same process. More than one deferred function may be registered per job attempt by calling this method repeatedly with different arguments. If the same function is registered twice with the same or different arguments, it will be called twice per job attempt.

Examples for deferred functions are ones that handle cleanup of resources external to Toil, like Docker containers, files outside the work directory, etc.

Parameters:

function (callable) – The function to be called after this job concludes.
args (list) – The arguments to the function
kwargs (dict) – The keyword arguments to the function

Return type:

None

Returns:: True if the service is still running, else False. If False then the service job will be terminated, and considered a success. Important point: if the service job exits due to a failure, it should raise a RuntimeError, not return False!
Return type:: bool
