class StrictVersion(vstring=None)

Bases: distutils.version.Version

Version numbering for anal retentives and software idealists. Implements the standard interface for version number classes as described above. A version number consists of two or three dot-separated numeric components, with an optional “pre-release” tag on the end. The pre-release tag consists of the letter ‘a’ or ‘b’ followed by a number. If the numeric components of two version numbers are equal, then one with a pre-release tag will always be deemed earlier (lesser) than one without.

The following are valid version numbers (shown in the order that would be obtained by sorting according to the supplied cmp function):

0.4 0.4.0 (these two are equivalent) 0.4.1 0.5a1 0.5b3 0.5 0.9.6 1.0 1.0.4a3 1.0.4b1 1.0.4

The following are examples of invalid version numbers:

1 2.7.2.2 1.3.a4 1.3pl1 1.3c4

The rationale for this version numbering system will be explained in the distutils documentation.

_create_indep2w_graph()[source]

Creates a simple graph with one workflow handling two independent workflows (with one simple calculation each). It was designed and used mainly to point out how the deletion behaviour works when setting call_work_forward to true: in this case if PWA is deleted, the somewhat independent PWB will also be deleted. Even worse, if call_calc_forward was also enabled, even the data provenance controlled by PWB (PCB and DOB) would be deleted as well. The graph is composed of the following nodes:

  • PW0: parent workflow, which calls both PWA and PWB.

  • PWA: it has a single call to PCA, with input DIA and output DOA.

  • PWB: it has a single call to PCB, with input DIB and output DOB.

This should look something like this (you can find a nicer version of this graph in the documentation, as it is the same used to explain the consistency rules):

_create_long_graph()[source]

Creates a straighforward graph with up to N=20 (currently) nodes. It checks if propagation works correctly, but it also can be used quickly to make preliminary timing profiling (increasing hardcoded N). The link scheeme looks like this:

+----+     +----+     +----+     +----+     +----+

_create_looped_graph()[source]

Creates a basic graph with one parent workflow (PWM) which first calls a child workflow (PWS) to choose one input from a set (DI1 from DI1-DI4), and then use it to perform a calculation (PCS) and obtain an output (DO1). The node PWM will call both PWS and PCS itself.

_create_minimal_graph()[source]

Creates a minimal graph which has one parent workflow (W2) that calls a child workflow (W1) which calls a calculation function (C0). There is one input (DI) and one output (DO). It has at least one link of each class:

  • CALL_WORK from W2 to W1.

  • CALL_CALC from W1 to C0.

  • INPUT_CALC from DI to C0 and CREATE from C0 to DO.

  • INPUT_WORK from DI to W1 and RETURN from W1 to DO.

  • INPUT_WORK from DI to W2 and RETURN from W2 to DO.

This graph looks like this:

      input_work     +----+     return
