1. Log all warnings, don't hide none of them
2. Write fatal messages (stop analysis) with error log level
3. Remove ugly timestamp counter from logrus output
4. Print nested module prefix in log
5. Make logger abstraction: no global logging anymore
6. Refactor config reading to config.FileReader struct to avoid passing
logger into every function
7. Replace exit codes hardcoding with constants in exitcodes package
8. Fail test if any warning was logged
9. Fix calculation of relative path if we analyze parent dir ../
10. Move Runner initialization from Executor to NewRunner func
11. Log every AST parsing error
12. Properly print used config file path in verbose mode
13. Print package files if only 1 package is analyzedin verbose mode,
print not compiling packages in verbose mode
14. Forbid usage of github.com/sirupsen/logrus by DepGuard linter
15. Add default ignore pattern to folint: "comment on exported const"
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
