72e137e344 Added "bodyclose" support
This commit adds full support for bodyclose linter
(https://github.com/timakin/bodyclose), which checks if an `http.Body`
element is correctly closed after usage.

Since it can be used via `go/analysis', I followed the `govet' example
as suggested by https://github.com/golangci/golangci-lint/wiki/How-to-add-a-custom-linter.

This commit is fully tested, and contains a (flawed) test program which
calls `http.Get()' on `https://google.com' and does not closes its
corresponding `http.Body'.

ed0b551070 Fix linting of preprocessed files
Preprocessed files like .qtpl.go quicktemplate Go files can have
//line directives. They map to a source .qtpl file.
This commit fixes linting of such files:
1. don't fail on AST cache loading
2. output Go filename not .qtpl or similar

Also, here we update golint to the upstream version.

127f89f072 update golang.org/x/tools
This brings in the upstream fix
1aadbdfdbb. (Upstream
issue is https://github.com/golang/go/issues/31163).

To create this commit, I did:

  vgo get golang.org/x/tools
  make update_deps
  cd cmd/golangci-lint
  go install -ldflags "-X 'main.version=$(git describe --tags)' -X 'main.commit=$(git rev-parse --short HEAD)' -X 'main.date=$(date)'"

Fixes #500

01fb8231f9 unparam: update unparam, and go mod vendor
This updates the unparam linter to the current version that has fewer
false positives. The go.{mod,sum} files and the vendor folder are
updated as follows:

export GO111MODULE=on
go get -u mvdan.cc/unparam
go mod tidy
go mod vendor

The unparam callgraph algorithm is no longer selectable. Ref:
https://github.com/mvdan/unparam/commit/e6a6d1c5
This is the reason for removing the c.CallgraphAlgorithm(us.Algo) line
from pkg/golinters/unparam.go.

Fix #324, relates #314

1. Update gocritic to the latest version
2. Use proper gocritic checkers repo, old repo was archived
3. Get enabled by default gocritic checks in sync with go-critic: don't
enable performance, experimental and opinionated checks by default
4. Support of `enabled-tags` options for gocritic
5. Enable almost all gocritic checks for the project
6. Make rich debugging for gocritic
7. Meticulously validate gocritic checks config

7705f82591 Update megacheck to the latest version
Also do following improvements:
  - show proper sublinter name for megacheck sublinters
  - refactor and make more simple and robust megacheck
  merging/optimizing
  - improve handling of unknown linter names in //nolint directives
  - minimize diff of our megacheck version from the upstream,
  https://github.com/golang/go/issues/29612 blocks usage of the upstream
  version
  - support the new `stylecheck` linter
  - improve tests coverage for megacheck and nolint related cases
  - update and use upstream versions of unparam and interfacer instead of forked
  ones
  - don't use golangci/tools repo anymore
  - fix newly found issues after updating linters

Also should be noted that megacheck works much faster and consumes less
memory in the newest release, therefore golangci-lint works noticeably
faster and consumes less memory for large repos.

cb5d1da986 Add support for home directory expansion for -c/--config flag
This change introduces the ability to use the tilde (`~`) character in your
`-c/--config` flag value to expand your home directory. If invoking this via the
command line with `--config ~/.golangci-lint.yaml`, the user's shell expands the
`~` to the home directory. However, if something is invoking the program for
you (like an editor) it may not do the expansion.

Fixes #289

Use go/packages instead of x/tools/loader: it allows to work
with go modules and speedups loading of packages with the help
of build cache.

A lot of linters became "fast": they are enabled by --fast now and
work in 1-2 seconds. Only unparam, interfacer and megacheck
are "slow" linters now.

Average project is analyzed 20-40% faster than before if all linters are
enabled! If we enable all linters except unparam, interfacer and
megacheck analysis is 10-20x faster!

5514c4393e Fix #17, #87: govet becomes SLOW linter by default
1. Allow govet to work in 2 modes: fast and slow. Default is slow.
In fast mode golangci-lint runs `go install -i` and `go test -i`
for analyzed packages. But it's fast only when:
  - go >= 1.10
  - it's repeated run or $GOPATH/pkg or `go env GOCACHE` is cached
  between CI builds
In slow mode we load program from source code like for another linters
and do it only once for all linters.

3. Patch govet code to warn about any troubles with the type
information. Default behaviour of govet was to hide such warnings.
Fail analysis if there are any troubles with type loading: it will
prevent false-positives and false-negatives from govet.

4. Describe almost all options in .golangci.example.yml and
include it into README. Describe when to use slow or fast mode of govet.

5. Speed up govet: reuse AST parsing: it's already parsed once by
golangci-lint.
For "slow" runs (when we run at least one slow linter) speedup by
not loading type information second time.

6. Improve logging, debug logging

7. Fix crash in logging of AST cache warnings (#118)

2b587b63d6
Load AST for fast linters in different way.
Use build.Import instead of manual parser.ParseFile and paths traversal. It allows:
1. support build tags for all linters.
2. analyze files only for current GOOS/GOARCH: less false-positives.
3. analyze xtest packages (*_test) by golint: upstream golint and
gometalinter can't do it! And don't break analysis on the first xtest
package like it was before.
4. proper handling of xtest packages for linters like goconst where
package boundary is important: less false-positives is expected.

Also:
1. reuse AST parsing for golint and goconst: minor speedup.
2. allow to specify path (not only name) regexp for --skip-files and
--skip-dirs
3. add more default exclude filters for golint about commits:
`(comment on exported (method|function)|should have( a package)?
    comment|comment should be of the form)`
4. print skipped dir in verbose (-v) mode
5. refactor per-linter tests: declare arguments in comments, run only
one linter and in combination with slow linter
