Keith Randall 2b8e60d464 runtime: make typehash match compiler generated hashes exactly If typehash (used by reflect) does not match the built-in map's hash, then problems occur. If a map is built using reflect, and then assigned to a variable of map type, the hash function can change. That causes very bad things. This issue is rare. MapOf consults a cache of all types that occur in the binary before making a new one. To make a true new map type (with a hash function derived from typehash) that map type must not occur in the binary anywhere. But to cause the bug, we need a variable of that type in order to assign to it. The only way to make that work is to use a named map type for the variable, so it is distinct from the unnamed version that MapOf looks for.

README.md

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.

To run just these tests, execute:

../bin/go run run.go

Standard library tests should be written as regular Go tests in the appropriate package.

The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:

it is most naturally expressed using the test runner; or
it is also applicable to gccgo and other Go tool chains.
