DataStore.GetStats() refactoring to simplify adding new fields #1704

veshij · 2021-10-21T07:20:22Z

What type of PR is this?: cleanup
What does this PR do / Why do we need it: In order to implement #1700 we need to add additional field to GetStats response.
Refactoring code to return struct instead list of ints to simplify future updates and decrease size of diffs.
Also adding AvailableAddresses() function implementing existing logic - since there are many places in the codebase where this number is calculated it makes sense to have in implemented as a function. AvailableAddresses() will be updated in following PR to treat cooldown IPs as 'taken'.
Expected to be a no-op change.

Testing done on this change: Y
Automation added to e2e: N
Will this break upgrades or downgrades. Has updating a running cluster been tested?: N/N
Does this change require updates to the CNI daemonset config files to work?: N
Does this PR introduce any user-facing change?: N (slightly changes log messages)

Can I get a review for the change pls? There will be one more on top of this diff which actually fixes the #1700

Hey @veshij, thanks for the update. Since this is one of series of changes that will have impacts on critical paths of VPC CNI, we have brought two more pairs of eyes to review your changes.

Hey @veshij, thanks for the update. Since this is one of series of changes that will have impacts on critical paths of VPC CNI, we have brought two more pairs of eyes to review your changes.

Thanks for update. This change itself should not change the behavior, next one will.
I'll publish it once this one is merged (I'm not sure there is a way to publish "stacked" PRs from forked repo).

@haouc gentle ping on the change. Or maybe you have some date in mind when I should come back to check status?

Sorry for the delay. The changes look good to me. Thanks for making efforts to clean up the code. Let's wait for a bit for comments from other reviewers.

It's been almost a month since I published this PR. I'd appreciate if someone can take a look and either request some changes or merge it.
Thank you!
