Python
To delete the suite definition, reload and begin using the Client Server API: First update test.py
#!/usr/bin/env python2.7
import os
import ecflow
print "Creating suite definition"
defs = ecflow.Defs()
suite = defs.add_suite("test")
suite.add_variable("ECF_HOME", os.getenv("HOME") + "/course")
suite.add_task("t1")
suite.add_task("t2")
print defs
print "Checking job creation: .ecf -> .job0"
print defs.check_job_creation()
print "Saving definition to file 'test.def'"
defs.save_as_defs("test.def")
To delete all suites in the server and reload modified test.def, we could update client.py
#!/usr/bin/env python2.7
import ecflow
print "Client -> Server: delete, then load a new definition"
try:
ci = ecflow.Client()
ci.delete_all() # clear out the server
ci.load("test.def") # load the definition into the server
ci.begin_suite("test") # start the suite
except RuntimeError, e:
print "Failed: " + str(e)
Rather than deleting, loading and beginning the suite every time you can replace
all or part of the suite. (i.e. to replace the whole suite see below)
Additionally we do not want the suite to start straight away. This can be done
by suspending the suite in ecflowview before reloading.
However we will need to remember to do this, each time. To get round this we will
suspend the suite use the Client Server API:
Modify client.py with:
#!/usr/bin/env python2.7
import ecflow
print "Client -> Server: replacing suite '/test' in the server, with a new definition"
try:
ci = ecflow.Client()
ci.suspend("/test") # so that we can resume manually in ecflowview
ci.replace("/test", "test.def")
except RuntimeError, e:
print "Failed: " + str(e)

| For brevity the examples that follow, will not show the loading of the suite. |
What to do
:- Suspend the suite using ecflowview or via python using ecflow.Client.suspend
- Create the new task
- Create t2.ecf by copying from t1.ecf
- Update python scripts test.py and client.py or test.def
- Replace the suite
- Resume the the suite using ecflowview
- In ecflowview, watch the two task running. They should run at the same time
