Hello gophers, We plan to issue Go 1.19.4 and Go 1.18.9 during US business hours on Tuesday, December 6. These minor releases include PRIVATE security fixes to the standard library. Following our security policy, this is the pre-announcement of those releases. Thanks, Jenny and Cherry for the

See my suggestion here: https://github.com/ebitengine/purego/issues/71#issuecomment-1332545306 For //go:norace and ABI wrapper functions, there's no instrument emitted. Your problem is that the compiler know there's a native ABI0 implementation for x_cgo_init, so calling it from assembly is f

[go-nuts] How to fix an awful marshal reflection hack

I have this code which works but has a horrible hack: ... nullable := false kind := field.Kind() // field's type is reflect.Value if kind == reflect.Ptr { // FIXME How can I improve upon this truly awful hack? switch field.Type().String() { case "*int", "*int8", "*uint8", "*int16", "*ui
