Mattermost Go Vet

This package contains mattermost-specific go-vet rules that are used to maintain code consistency in mattermost.

Included analyzers

  1. equalLenAsserts - check for (require/assert).Equal(t, X, len(Y))
  2. inconsistentReceiverName - check for inconsistent receiver names in the methods of a struct
  3. license - check the license header
  4. openApiSync - check for inconsistencies between OpenAPI spec and the source code
  5. structuredLogging - check invalid usage of logging (must use structured logging)
  6. mlogFieldNaming - check that mlog field keys are snake_case
  7. tFatal - check invalid usage of t.Fatal assertions (instead of testify methods)
  8. apiAuditLogs - check that audit records are properly created in the API layer
  9. rawSql - check invalid usage of raw SQL queries instead of using the squirrel lib
  10. emptyStrCmp - check for idiomatic empty string comparisons
  11. pointerToSlice - check for usage of pointer to slice in function definitions
  12. mutexLock - check for cases where a mutex is left locked before returning
  13. wrapError - check for original errors being passed as details rather than wrapped
  14. noSelectStar - check for SQL queries using SELECT * which breaks forwards compatibility
  15. requestCtxNaming - check that request.CTX parameters are consistently named 'rctx'
  16. sortSlices - check for sort.Strings/sort.Ints/sort.Slice/sort.SliceStable calls, which should use the slices package instead
