This setting will be removed in a future release, Go 1.22 at the earliest.

### Go 1.10

Go 1.10 changed how build caching worked and added test caching, along
with the [`gocacheverify`, `gocachehash`, and `gocachetest` settings](/cmd/go/#hdr-Build_and_test_caching).
There is no plan to remove these settings.

### Go 1.6

Go 1.6 introduced transparent support for HTTP/2,

		package due to a non-default GODEBUG=gocachetest=... setting.

	/godebug/non-default-behavior/gocacheverify:events
		The number of non-default behaviors executed by the cmd/go
		package due to a non-default GODEBUG=gocacheverify=... setting.

	/godebug/non-default-behavior/gotypesalias:events
		The number of non-default behaviors executed by the go/types
		package due to a non-default GODEBUG=gotypesalias=... setting.

This may make fuzzing less effective, temporarily.

The GODEBUG environment variable can enable printing of debugging
information about the state of the cache:

GODEBUG=gocacheverify=1 causes the go command to bypass the
use of any cache entries and instead rebuild everything and check
that the results match existing cache entries.

GODEBUG=gocachehash=1 causes the go command to print the inputs
