Yes, you need to unmarshall the result to access individual fields in the
result.result variable. The STAF Python User's Guide at
http://staf.sourceforge.net/current/STAFPython.htm provides information on
unmarshalling, as well as examples. Note that you don't have to
unmarshall the STAFResult's result string returned by the submit() method
(assuming auto-unmarshalling is enabled for the handle which it is by
default). Instead, you can directly access the result's marshalling
context in variable result.resultContext, and/or the root object of the
result's marshalling context in variable result.resultObj.
For example, here's a snippet of Python code that submits a PROCESS START
request to run "java -version" and prints the stdout/stderr data
containing the Java version if it succeeded:
command = 'java -version'
request = 'START SHELL COMMAND %s RETURNSTDOUT STDERRTOSTDOUT WAIT' %
(wrapData(command))
print '\nSTAF %s PROCESS %s' % (machine, request)
result = handle.submit(machine, 'PROCESS', request)
if result.rc != STAFResult.Ok:
print 'STAF local PROCESS %s failed, RC=%s Result=%s' % (request,
result.rc, result.result)
sys.exit(1)
# The result object is a map (aka Python dictionary) containing fields
such as "rc" and "fileList"
processMap = result.resultObj
if processMap['rc'] != '0':
# The process failed
# The formatObject API "pretty" prints the marshalled result in a
formatted manner
print 'Process failed since returned non-zero RC: %s\n%s' %
(processMap['rc'], formatObject(result.resultContext))
sys.exit(1)
# You can use the formatObject API to "pretty" print the marshalling
context for the result in a formatted manner
print '\nResult:\n%s' % (formatObject(result.resultContext))
# The process's stdout/stderr is provided in the fileList field in the
result object.
# The value for 'fileList' is a list of the returned files where each
entry in the list consists of a map that contains keys 'rc' and 'data'.
# In this PROCESS START request, we returned one file, stdout, and
returned stderr to this same file.
# Note that the STAF User's Guide defines the result for each request
submitted to an internal STAF service.
print 'java -version: %s' % (processMap['fileList'][0]['data'])

Re: Re: [staf-users] Question about trust level settings between machines
and running PROCESS
Sharon,
You are wonderful. I thought it might be something simple. I can now run
my command and get the result.results.
Question: Now that I can run the command successfully I see result.result
has what I expected at the end of the output.
My question, how do I get everything from "java -version"
to the end of result.result and not all the characters before "java
-version"?
For example in my Python debugger I have the following:
(Pdb) print result.result
@SDT/*:893:@SDT/{:587::13:map-class-...@sdt/{:559::35:STAF/Service/Process/completioni...@sdt/{:261::4:k...@sdt/[3:189:@SDT/{:56::12:display-n...@sdt/$S:11:Return

OpenJDK Runtime Environment (IcedTea6 1.6) (fedora-30.b16.fc11-i386)
OpenJDK Server VM (build 14.0-b16, mixed mode)
I believe it has something to do with marshalling structured data, but I
have not read enough of the users guide to know how I would remove all the
extra stuff before the "java version" output from result.result.
Any help would be appreciated. Probably something easy like the above
trust configuration issue.
Many thanks,
Regards,
Bill
