Fixing issue where REST handlers wouldn't work with apps that had copied code

Reference #2270

History

#1 Updated by Luke Murphey almost 6 years ago

The error is;

ImportError: cannot import name LookupEditor

from /home/SW/splunk/etc/apps/lookup_editor/bin/lookup_backups_rest_handler.py

#2 Updated by Luke Murphey almost 6 years ago

Questions:
  • What is the path that is used for resolving libraries?
    • See note, It does include
  • Does a relative import work?
    • No, it is in the same path
  • Do the hosts have the modules available?
    • Yes
  • Does manually setting the sys.path to include the current directory work?
    • No
  • Why does it not output any logs?
    • It does
  • Could another app be including the lookup editor Python code? If so, would inserting the path first help?
Observations:
  • The RHs are not starting, indicating: cannot import name LookupEditor
  • The sys.path looks like it ought to work

Can set the import path to the script directory via:

import sys
import os
sys.path.append(os.path.dirname(os.path.abspath(__file__)))

#5 Updated by Luke Murphey almost 6 years ago

I tried uploading a version of the app that does two things:

  1. Try using the path set from the script directory
  2. Outputs sys.path before starting

The app still doesn't work.

#7 Updated by Luke Murphey almost 6 years ago

Can dump apps with:

| rest /services/apps/local | table title label description
