Python utils for writing gamayun job scripts
Python utilities for Gamayun
This is a package containing python utilities for writing Gamayun jobs. Main Gamayun repository can be found here.
Getting the package
Install the package with the following command:
pip3 install gamayun-utils
This package depends on gprcio, which needs C/C++ compilers installed on the system. Needed dependencies on Alpine are:
apk add --no-cache python3 \ && apk add --no-cache gcc \ && apk add --no-cache g++ \ && apk add --no-cache libc-dev \ && apk add --no-cache linux-headers \ && apk add --no-cache python3-dev
Note that suggested way of using Gamayun is with Docker, so you don't have to install these dependencies locally. If you are using Docker, there is an image containing Gamayun and Gamayun Python utilities here.

Reporting results and errors
Functions for reporting results or errors from the script are following:
This function is used when the result we want to report is a list of strings
This function is used when the result we want to report is a list of maps
def report_result_with_maps_and_strings(mapResults, stringResults)
This function is used when the result we want to report is a list of strings and a list of maps
This function is used when we want to report error which will be forwarded through the notifier interface
Note that once result or error is reported for the script/gamayun-job, Gamayun will stop listening for results/errors for that job, so in entire job there should be only one call to any of the
Executing the script logic
There is a function with the following signature in this package:
All the script logic should be placed in some function and that function should be given to
run_gamayun_script_logic as argument as this will ensure that all uncought exceptions are caught and reported as errors to Gamayun.
So, a job script file should look something like this:
from gamayun_utils import report_result_with_maps_only from gamayun_utils import report_error from gamayun_utils import run_gamayun_script_logic def script_logic(): # place the script logic here if OK: report_result_with_maps_only(results) else: report_error(error) run_gamayun_script_logic(script_logic)
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
