I nearly make all test pass, but after merge master and resolve conflicts, I find tidb-tools have introduce module and it use a pd version conflict with here.

One thing that can help avoid disrupting workflows is to do the switch but to use go mod's vendoring support (we did this in pd).
Even if we don't want to commit that, it is very helpful for code review.

Good suggestion, we can adopt it in tidb-tools. @gregwebs
vendor is not included here because:

  1. tidb update parser frequently, and that will make this repo expansion quickly
  2. vendor is not recommend by the Go team

I think go.mod needs a more thorough review still. We may have a repeat of the same issue we had in PD of pulling in some odd dependencies tikv/pd#1269 (review)

Yeah, the hardest step is resolving the dependency and make CI work.

Now it's time to polish it, feel free to send some PRs. @gregwebs

I won't be sending PRs any time soon. You should be able to ask @disksing what he did.

Why there is an incompatible? Does it mean that we have dependencies that import different versions of etcd?

@gregwebs In fact, in the case where the vendor is deleted, it is difficult to know the difference between the dependencies used by go.mod and the previous vendor dependencies. This PR may have inadvertently changed a lot of dependent versions.
