* put validate function under base rule struct
* better validation error wording
* add Fingerprint and Description methods to Issue struct, made codeclimate reporter easier to read, checkstyle output is now pretty printed
Ensure that `unused` is always the last
in execution order. It can speed up packages loading
a bit.
Refactor enabled linters set to remove extra logging.
Relates: #944
Run all linters per package. It allows unloading package data when it's
processed. It dramatically reduces memory (and CPU because of GC) usage.
Relates: #337
* update staticcheck
Don't fork staticcheck: use the upstream version.
Remove unneeded SSA loading.
* Cache go/analysis facts
Don't load unneeded packages for go/analysis.
Repeated run of go/analysis linters now 10x faster
(2s vs 20s on this repo) than before.
Treat Go source files as plain text files by misspell: it allows detecting
issues in strings, variable names, etc. Also, it's the default mode of
a standalone misspell tool.
Also, implement richer and more stable auto-fix of misspell issues:
now it can fix multiple issues in one line.
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.
Relates: #316, #466, #467, #468
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!
1. Rename in a backward compatible way
2. Remove gosec default exclude list because gosec is already disabled
by default.
3. Warn about unmatched linter names in //nolint directives
4. Process linter names in //nolint directives in upper case
5. Disable gosec for golangci-lint in .golangci.yml
1. Support unparam linter and fix found issues
2. Replace forked mvdan.cc/lint and mvdan.cc/interfacer with the
upstream ones
3. Minimize forked megacheck: move the most of it's code to this repo
4. Use golang.org/x/tools/go/ssa import path instead of custom fork
paths
5. In golang.org/x/tools/go/{ssa,callgraph} use changed code from
honnef.co/go/tools
6. Add megacheck.check-unexported option: it found some issues in
the repo, fixed them all
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)
