Python
We can ask the python script to write out the defs as ‘.def’ definition file
This can also be useful for debugging when you have a complex suite definition:
| Code Block | ||||
|---|---|---|---|---|
| ||||
#!/usr/bin/env python2.7 import os |
from ecflow import Defs,Suite,Task,Edit print "Creating suite definition" |
|
home = |
os.path.join(os.getenv("HOME"), |
"course") defs = Defs( Suite('test', Edit(ECF_HOME=home) |
, Task('t1'))) 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 restore the definition from file 'test.def' we can use: # restored_defs = ecflow.Defs("test.def") |
If you called “defs.save_as_defs()” the file test.def will be written.
This can be loaded in the server as described earlier. (See Text)
Since the Suite Definition API allows the definition to be built in memory,
it can be directly loaded into the ecflow_server.
This can be done by using ecflow.Client python class.
try:
print "Load the in memory definition(defs) into the server"
ci = ecflow.Client()
ci.load(defs)
except RuntimeError as e:
print "Failed:", e
However it is recommended that the building of the suite definition is separated
from loading it into the server. The loading should be placed into a file. client.py.
#!/usr/bin/env python2.7
import ecflow
try:
print "Loading definition in 'test.def' into the server"
ci = ecflow.Client()
ci.load("test.def") # read definition from disk and load into the server
except RuntimeError as e:
print "Failed:", e
If everything is OK, you should have defined a suite in the server.
Have a look in the window running the ecflow_server, and look at the log file
What to do
- Load the definition file. Choose between loading as a text file, or using python api (Update $HOME/course/test.py to write out the definition to disk)
- If using python examine test.def and create the file client.py.
- Check the log file.
If you encounter errors associated with loading the suite twice, then you can delete the 'test' suite in the server.
| Code Block |
|---|
ecflow_client --delete /test |
The definition can then be re-loaded.
Alternatively you can use replace , please type the following for help on replace.
| Code Block |
|---|
ecflow_client --help replace ecflow_client --replace=/test test.def # e.g. to replace the whole suite ecflow_client --replace=/test/t1 test.def # or one node |
