- Why I did it
Updated package syntax to Python3

- How I did it
Used 2to3 tool to update the syntax. Also, added print function import from future when required

- How to verify it
Unit test cases pass.

- Which release branch to backport (provide reason below if selected)
N/A

is this necessary? https://www.tutorialspoint.com/python3/dictionary_has_key.htm

I can see python3 still have this support.

indeed. Not sure why 2to3 converted. I used 2to3 -f all switch. Are there recommended switches to use?

removed in 3.1:

https://docs.python.org/3.1/whatsnew/3.0.html

Can confirm, has_key() has been removed in Python 3. in is the new proper way to check for a key.

This line should not be necessary for backward-compatibility with Python 2.7, but it won't hurt anything.

I was getting error related to the print function syntax:

Running sonic-cfggen -y /sonic/src/sonic-config-engine/tests/test.yml -t /sonic/src/sonic-config-engine/tests/test.j2 -------------------------------------------------------------------------------------------------------------------------------------------------- Captured stderr call -------------------------------------------------------------------------------------------------------------------------------------------------- Traceback (most recent call last): File "/sonic/src/sonic-config-engine/tests/../sonic-cfggen", line 39, in <module> from minigraph import minigraph_encoder File "/sonic/src/sonic-config-engine/minigraph.py", line 291 print("VNI must be an integer (use default VNI %d instead)" % vni_default, file=sys.stderr) ^ SyntaxError: invalid syntax

Oh, maybe the file= argument was added in Python 3.0.

Edit: I figured out why from __future__ import print_function is not always needed in Python 2. In Python 2, adding parentheses around the arguments to print does not change it into a function call; it simply translates to "pass this tuple of args to the print statement". This works fine in Python 2, and in Python 3, it works because it is interpreted as a function call. However, adding the file= parameter won't work in Python 2 because print is not technically a function. This is the case when from __future__ import print_function is needed.

my suggestion is to enable py3 package build as soon as possible so that we have build check even though we may not using them in our image, otherwise it can be degraded.

The `ipv6_found` Jinja2 variable added to the supervisor config file goes out of scope before it is read. **- How I did it** 1. Rename the `wait_for_intf.sh` script to `wait_for_link.sh` 2. Use the Jinja2 "namespace" construct to fix the scope issue **- How to verify it** Ensure all processes in the radv container start properly under the correct conditions (i.e., whether or not there is at least one VLAN with an IPv6 address assigned). * [sonic-utilities] Update submodule (sonic-net#5233) * src/sonic-utilities d5fdd74...17fb378 (7): > [sonic-installer] Import re module (sonic-net#1061) > [fast-reboot]: Fix fail to execute fast-reboot problem (sonic-net#1047) > [config] Reduce Calls to SONiC Cfggen (sonic-net#1052) > [filter-fdb] Call Filter FDB Main From Within Test Code (sonic-net#1051) > [sflow_test.py]: Fix show sflow display.

It will then service those requests and send a response back to the requestor. This PR only introduces the host service infrastructure.

Zeroing this old relica makes sure that there is nothing left of the old partition lying around. There won't be any risk of having Aboot corrupt the new filesystem because of the old relica.

@tahmed-dev: You modified the sonic-config-engine syntax to support Python 3. However you did not modify the build process to build and install a Python 3 version of the sonic-config-engine package. Is there a reason why not?

tahmed-dev · 2020-09-22T00:12:52Z

@jleveque no particular reason. let me take note of that.

jleveque · 2020-09-22T00:15:55Z

Thanks. I ask because I am working on creating a Python 3 sonic-utilities package, and the unit tests require sonic-config-engine, so we need a Python 3 sonic-config-engine package first.

I'll dedicate some time on Wed to address this.
