I have gone through documentation of the auto upgrade helper ,like how to use and prerequisites and all.

Can i get any examples like how to use the helper tool to upgrade a recipe,

Also how can i verify this tool like how it is working

for verifying i took a poky(warrior) layer as a reference example . 

With this i checked out older

commit hash (https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?h=warrior&id=0c011f61e67b33746b201db99bd25842c083cfa7).

so that when i use the auto upgrade tool on any recipe which had older changes can get updated to current commit changes.

With this when i checked recipes and their versions map there were some recipes which had this version difference(eg: python: 3.7.2 present 3.7.7).

Now if I run the tool to update the python recipe (like upgrade-helper.py python), I don't see any changes in the recipe at all.

I have followed the steps documented here:

https://docs.yoctoproject.org/3.2.4/dev-manual/dev-manual-common-tasks.html#using-the-auto-upgrade-helper-auh.

 

Are these steps followed for verification steps  correct or if you can suggest any other procedure if you can suggest that will be helpful
