Staticcheck 2024.1 (v0.5.0)

Backwards incompatible changes

Staticcheck 2024.1 contains the following backwards incompatible changes:

• The keyify utility has been removed. The recommended alternative is gopls.
• staticcheck -merge now exits with a non-zero status if any problems have been found.

Improved Go 1.22 support

This release updates Staticcheck’s database of deprecated standard library APIs to cover the Go 1.22 release. Furthermore, checks have been updated to correctly handle the new “for” loop variable scoping behavior as well as ranging over integers.

Added Go 1.23 support

Staticcheck 2024.1 has full support for iterators / range-over-func. Furthermore, SA1015 will skip any code targeting Go 1.23 or newer, as it is now possible to use time.Tick without leaking memory.

Improved handling of Go versions

Go 1.21 more rigorously defined the meaning of the go directive in go.mod files, as well as its interactions with //go:build go1.N build constraints. The go directive now specifies a minimum Go version for the module. Furthermore, it sets the language version that is in effect, which may change the semantics of Go code. For example, before Go 1.22, loop variables were reused across iterations, but since Go 1.22, loop variables only exist for the duration of an iteration. Modules that specify go 1.22 will use the new semantics, while modules that specify an older version will not.

Individual files can both upgrade and downgrade their language version by using //go:build go1.N directives. In a module that requires Go 1.22, a file specifying Go 1.21 will experience the old loop variable semantics, and vice versa. Because the Go module as a whole still specifies a minimum version, even files specifying an older version will have access to the standard library of the minimum version.

Staticcheck 2024.1 takes all of this into consideration when analyzing the behavior of Go code, when determining which checks are applicable, and when making suggestions. Older versions of Staticcheck were already aware of Go versions, but 2024.1 works on a more fine-grained, per-file basis, and differentiates between the pre- and post-1.21 semantics of the go directive.

The -go command line flag continues to exist. It will override any module-based version selection. This is primarily useful for Go modules that target older Go versions (because here, the go directive didn’t specify a minimum version), or when working outside of Go modules.

To prevent misinterpreting code, Staticcheck now refuses to analyze modules that require a version of Go that is newer than that with which Staticcheck was built.

Checks

New checks

The following checks have been added:

• SA1031 flags overlapping destination and source slices passed to certain encoding functions.
• SA1032 flags calls to errors.Is where the two arguments have been swapped.
• SA4032 flags impossible comparisons of runtime.GOOS and runtime.GOARCH based on the file’s build tags.
• SA6006 flags io.WriteString(w, string(b)) as it would be both simpler and more efficient to use w.Write(b).
• SA9009 flags comments that look like they intend to be compiler directives but which aren’t due to extraneous whitespace.

Changed checks

The following checks have been improved:

• QF1001 no longer panics on expressions involving “key: value” pairs (issue 1484).
• S1008 now understands that some built-in functions never return negative values. For example, it now negates len(x) > 0 as len(x) == 0 (issue 1422).
• S1009 now flags unnecessary nil checks that involve selector expressions (issue 1527).
• S1017 no longer flags if else branches (issue 1447).
• SA1006 now detects more Printf-like functions from the standard library (issue 1528).
• SA1015 now skips any code targeting Go 1.23 or newer (issue 1558).
• SA1029 now flags uses of the empty struct (struct{}) as context keys (issue 1504).
