There was a problem hiding this comment.
Parenthesis not required here (lets remove to be more python-way consistent).
Also, in which cases bool(version_info) == False ? Let's teat it as undefined platform error, otherwise we hide the problem and keep pmon in the list
There was a problem hiding this comment.
At the beginning of the file lets initialize asic_type like this:
try:
asic_type = version_info['asic_type']
except KeyError, TypeError:
click.abort('undefined ASIC type')
Any subsequent code that uses asic_type knows that it is initialized correctly

…aidump_by_route_size (sonic-net#2972) * * [saidump] • Saidump for DNX-SAI sonic-net/sonic-buildimage#13561 Solution and modification: To use the redis-db SAVE option to save the snapshot of DB each time and recover later, instead of looping through each entry in the table and saving it. (1) Updated sonic-buildimage/build_debian.sh, to install Python library rdbtools into the host. (2) Updated sonic-buildimage/src/sonic-sairedis/saidump/saidump.cpp, add a new option -r, which updates the rdbtools's output-JSON files' format. (3) Add a new script file: files/scripts/saidump.sh, to do the below steps For each ASIC0, such as ASIC0, #1. Save the Redis data. sudo sonic-db-cli -n asic$1 SAVE > /dev/null #2. Move dump files to /var/run/redisX/ docker exec database$1 sh -c "mv /var/lib/redis/dump.rdb /var/run/redis$1/" #3. Run rdb command to convert the dump files into JSON files sudo python /usr/local/bin/rdb --command json /var/run/redis$1/dump.rdb | sudo tee /var/run/redis$1/dump.json > /dev/null #4. Run saidump -r to update the JSON files' format as same as the saidump before. Then we can get the saidump result in standard output. docker exec syncd$1 sh -c "saidump -r /var/run/redis$1/dump.json" #5. clear sudo rm -f /var/run/redis$1/dump.rdb sudo rm -f /var/run/redis$1/dump.json (4) Update sonic-buildimage/src/sonic-utilities/scripts/generate_dump, replace saidump with saidump.sh * * [saidump] • Saidump for DNX-SAI sonic-net/sonic-buildimage#13561

- What I did
Don't start/stop pmon during config reload since pmon is triggered by syncd.
This PR depends on [syncd.sh] stop pmon ahead of syncd in flows except warm reboot #7
- How I did it
For Mellanox platform, remove pmon from the services_to_stop and service_to_start list.
- How to verify it
execute "config reload" and "systemctl restart swss.service" and check whether all dockers start.
- Previous command output (if the output of a command-line utility has changed)
- New command output (if the output of a command-line utility has changed)
