Note that this does NOT upgrade to xDS v3. That will come in a future PR.
Additionally:
- Ignored staticcheck warnings about how github.com/golang/protobuf is deprecated.
- Shuffled some agent/xds imports in advance of a later xDS v3 upgrade.
- Remove support for envoy 1.13.x but don't add in 1.17.x yet. We have to wait until the xDS v3 support is added in a follow-up PR.
Fixes#8425
And fix the 'value not used' issues.
Many of these are not bugs, but a few are tests not checking errors, and
one appears to be a missed error in non-test code.
We occasionally see the lint job fail due to this timeout. Likely when the node running lint is under heavy load, because normally it runs much faster.
This commit increases the timeout substantially to work around that problem.
Three of the checks are temporarily disabled to limit the size of the
diff, and allow us to enable all the other checks in CI.
In a follow up we can fix the issues reported by the other checks one
at a time, and enable them.
Using golangci-lint has a number of advantages:
- adding new linters becomes much easier, its a couple lines of yaml config
instead of more bash scripting
- it enables whitelisting of issues using inline comments or regex
- when running multiple linters less work is done. The parsed source can be reused
by multiple linters
- linters are run in parallel to reduce CI runtime.
