## Description
- Use tools methodology to use canonically versioned tools/binaries (e.g. golangci-lint)
- This makes it so that all environments and developers use the same versions of tools (no need to rely on hacky docker containers)
- Update makefile
- Address linting errors

{,scripts/}Makefile:
- Remove gometalinter, install golangci-lint.
- Remove distinction between tools and devtools.
Just tools is enough.
- test_lint -> lint
Migrating away from underscore separated names.
- Remove unnecessary targets.
- Drop tendermint/lint. Incompatbile with golangci-lint
and no longer necessary anyway.
- Fix misleading message in go-mod-cache.
- New ci-target to avoid download tools twice.
- Run tests with -mod=readonly.
Port tools/gometalinter.json to .golangci.yml
Update CircleCI config accordingly.
Closes: #3896
Replace sha1sum with jack's gosum and get rid of
vendor-deps.
Also don't compute hash on vendor/ contents.
Instead hash go.sum.
Disable unconvert lint check. It does not
work very well with go mod.
Remove update_vendor_deps once and for all.
Upgrade to go 1.12
Closes: #3919#3630
This is basically copying over @anton's great script!
Also had to run `make format` to make this pass `test_lint`.
This PR also makes the make commands for tools further align
with the tendermint implementation.
* Adds a Min function to Int, and uses that in the slash function
* Adds a getHeight helper function to iavlstore
* Adds a splitPath function to baseapp
* Changes cyclo param from 10 to 11
Gocyclo is a code complexity linter. It uses cyclomatic complexity.
Cyclomatic complexity essentially measures the number of different
paths code could go through. (The conditional in a for loop counts
as adding one path) It looks at this on a per-function level. The
idea that this would be enforcing is that if there are too many
different paths code can go through in a function, it needs to be
better split up. (A function with too many code paths is hard to
reason about)
The complexity which we want the linter to start failing on is
configurable. The default is 10. Change the "Cyclo" parameter in
`tools/gometalinter.json` to try other values.
* tools: Add unparam linter
unparam detects unused parameters in functions, and a parameter to
a function which only ever takes on one value. The latter is an
indication that more tests are required.
There are many nolints in this PR, as I believe that writing tests
to fix alot of these situations is out of scope for this PR / it
will be changed in future commits. There are some nolints for
when we have to comply to normal api's.
* crypto/keys no longer used by x/gov/client/rest/rest.go
* tools: Add ineffassign linter
This errors on assignments that don't actually do anything. i.e.
x, err := myFunc(1)
y, err = myFunc(2)
This will call out that the first function's call error was never
used.
* Fix makefile, add misspell to makefile
Previously, the install scripts weren't installing golint and gometalinter.
This commit fixes this, and installs tendermints linter, and the HEAD of
the gometalinter repository. Now make all should work.
