requestid
package originally used typeint
and value0
as its context key, which may potentially collide with other context keys. This PR uses an unexported type for its context key.requestid
package was ingo/support/context
, but it ischi
specific and only used by horizon. This PR moves it intohorizon/internal
.main.go
for non-command line source. This PR renames the files tocontext.go
andcontext_test.go
