Consolidate common SONiC Python-language functionality into one shared package (sonic-py-common) and eliminate duplicate code.
The package currently includes four modules:
- daemon_base
- device_info
- logger
- task_base
NOTE: This is a combination of all changes from https://github.com/Azure/sonic-buildimage/pull/5003, https://github.com/Azure/sonic-buildimage/pull/5049 and some changes from https://github.com/Azure/sonic-buildimage/pull/5043 backported to align with the 201911 branch. As part of the 201911 port, I am not installing the Python 3 package in the base image or in the VS container, because we do not have pip3 installed, and we do not intend to migrate to Python 3 in 201911.
* Updated Makefile infrastructure to build debug images.
As a sample, platform/broadcom/docker-orchagent-brcm.mk is updated to add a docker-orchagent-brcm-dbg.gz target.
Now "BLDENV=stretch make target/docker-orchagent-brcm-dbg.gz" will build the debug image.
This debug image can be used in any linux box to inspect core file. If your module's external dependency can be suitably mocked, you my even manually run it inside.
"docker run -it --entrypoint=/bin/bash e47a8fb8ed38"
You may map the core file path to this docker run.
* Dropped the regular binary using DBG_PACKAGES and a small name change to help readability.
* Tweaked the changes to retain the existing behavior w.r.t INSTALL_DEBUG_TOOLS=y.
When this change ('building debug docker image transparently') is extended to all dockers, this flag would become redundant. Yet, there can be some test based use cases that rely on this flag.
Until after all the dockers gets their debug images by default and we switch all use cases of this flag to use the newly built debug images, we need to maintain the existing behavior.
* Build a Docker base image based on Debian Stretch
* Build a config-engine Docker image based on Stretch
* Do not install socat from Debian repo
* Add changes that were made to docker-base since this PR was opened
