Yes, cfgagent might be a good name for the directory. Will move intfconfd, vlanconfd and debug cli implmentation cfgmgrtest there. Actually that was the initial arrangement.

The table names for different DB are different. a vector might not be a good fit here.

I am not sure you are talking about the same thing. I mean that use a copied instance may cost much than a reference. #Closed

exec [](start = 10, length = 4)

check the return value? #Closed

Error has been logged in exec if there is any. In this case, error is not really expected.
That is common question for many functions in sonic, end 2 end feedback loop is missing.

I don't agree. Locally if there is any error happens, you should check the return code all the levels up the stack, and quit as soon as possible, or recover depending on the situation. #Closed

fine. But I don't see the same criteria applied in orchagent, syncd, those python code and etc.
We could start the endeavor from this.

isIntfStateOk [](start = 15, length = 13)

suggest name: readyIntf

Honestly I don't see readyIntf a better name than isIntfStateOk, we do put state ok in stateDB though it is not checked for now. If you insist on changing the name, I could do it.

Just checking the code, there is nothing about "Ok" state. So I guess the original name is not perfect.

Ok, will add code to check the state:

127.0.0.1:6379[6]> hgetall "PORT_TABLE|Ethernet47"

"state"

"ok"

I don't see that you check "ok"

can you rename to intfmgr?

The role of confd, orchagent, syncd are blurred, it is hard to have a clear cuts of different roles they are playing, so mgr can include all functions, which manages both asic and linux setup. therefore I prefer mgr name

Ok, will rename them to intfmgr and vlanmgr. For switch table level configuration, besides switchmgr process itself, the configuration may be used by multiple function modules like VLAN.

I plan to keep the class name of VlanConf, IntfConf and SwitchConf, let me know if you have other suggestions.

So process and binary name will be changed to VlanMgr/IntfMgr/SwitchMgr, you want to change the internal class name to xxxMgr too? IntfConfd/VlanConfd were chosen per the offline meeting discussion. Yes, class name may be changed.

add more comments here, retry. Later, we need to add subscriber for the state db to get notification when the port/lag/vlan is created.
