Ecflow change possible impact after upgrading

This release corrects some faulty triggers expression, that may require validation:

...
family f1
   task t1
       trigger f1 == aborted
   task t2
       trigger ./f1 == aborted

...
family f1
   task t1
        trigger ../f1 == aborted
   task t2
        trigger ../f1 == aborted

If your suite contains wrongly defined triggers like the one on the left, they will never be satisfied and therefore the tasks or families depending on them will not run.

It is highly recommended that whenever you migrate to version 4.12 or beyond from an earlier release, you run the checks below. This will highlight problems early, and save you a lot of debug time.

This can be done before we migrate.

•  If you use python to generate your suite definitions, then simple make sure you run(defs.check())

  module load ecflow/ new ... # build your python suite definitions def = ... print defs.check()  #  this will print any problems with triggers and inlimit

• Alternatively you can use:

  module swap ecflow/ 4.12.0 ecflow_client --get > tmp.def ecflow_client --load tmp.def check_only #  this will print any problems with triggers and inlimit

If you have migrated to the new release, to check all your suites run:

You have all the details in the ecflow release 4.12.0.
