### Go command {#go-command}
|
|
|
|
### Cgo {#cgo}
|
|
|
|
Cgo currently refuses to compile calls to a C function which has multiple
|
|
incompatible declarations. For instance, if `f` is declared as both `void f(int)`
|
|
and `void f(double)`, cgo will report an error instead of possibly generating an
|
|
incorrect call sequence for `f(0)`. New in this release is a better detector for
|
|
this error condition when the incompatible declarations appear in different
|
|
files. See [#67699](/issue/67699).
|
|
|
|
### Vet
|
|
|
|
The new `tests` analyzer reports common mistakes in declarations of
|
|
tests, fuzzers, benchmarks, and examples in test packages, such as
|
|
malformed names, incorrect signatures, or examples that document
|
|
non-existent identifiers. Some of these mistakes may cause tests not
|
|
to run.
|
|
|
|
This analyzer is among the subset of analyzers that are run by `go test`.
|
|
|
|
### GOCACHEPROG
|
|
|
|
The `cmd/go` internal binary and test caching mechanism can now be implemented
|
|
by child processes implementing a JSON protocol between the `cmd/go` tool
|
|
and the child process named by the `GOCACHEPROG` environment variable.
|
|
This was previously behind a GOEXPERIMENT.
|
|
For protocol details, see [#59719](/issue/59719).
