The idea here is to cherry-pick the commits from 7690 to allow Samuel to continue his work.

Migrate WorkflowAlgorithms to new API

re #7690

Changeset: b04a293a66a50e99af2aa0cc93dbf7a30f0745dc

moved to ticket #7760

[Gesner Passos]

Solves the system tests that are failing

the problem was with importing the modules in the very beggining. It was necessary to let the modules to be imported in run time.

re #7690

moved to ticket #7760

Correct WorkflowAlgorithms for IndirectAnalysis

It is necessary to import the modules later un RunTime, otherwise, it fails if it tries in the very beggining.

Tester:

• executing the reductions involving indirect analysis, should not print warning that it is calling the old API anymore.
• code review to verify that old api is not being called.

[Samuel Jackson]

Everything appears to still work in the Indirect interface and there are no longer any python warnings about the old API. Visual code inspection show changes appear to be reasonable.

[Gesner Passos]

Some of the workflow algorithms used the os that was imported 'by chance', automatically from the old api.

It is necessary to add the import line now.

Besides, these workflow algorithms do not have unit tests, and a ticket but be created to check that their wrapper function is being executed correctly.

[Gesner Passos]

Include the os module for some workflow algorithms

The os was available before in the old api when import all, it has passed without notice.

Now, it has been bassed to those scripts using the os module.

re #7760

Changeset: 5cd5c2fcc61c2d41938ee065af6142aca3d09c71

[Gesner Passos]

Change priority of (testing) to critical. This and #7703 block us to switch off old API.

[Martyn Gigg]

Testing only pertains to the last commit as the rest was actually merged to master.
