                      7685     ~0%     {3} r1 = JOIN ActionController::ActionControllerContextCall#ff#shared WITH Method::Method::getName_dispred#ff ON FIRST 1 OUTPUT Rhs.1, Lhs.1 'controllerClass', Lhs.0 'this'

                                       return r6
```

Joining on enclosing module and name simultaneously yields a much better join.

67962cb93d Ruby: Fix bad join in access predicate 
Joining on variable name alone is a bad thing:

```
[2022-01-25 11:13:20] (228s) Tuple counts for Variable::Cached::access#ff#shared/3@868b54tu after 3m37s:
                      112554    ~0%     {3} r1 = JOIN Variable::VariableReal::getNameImpl_dispred#ff WITH Variable::VariableReal::getDeclaringScopeImpl_dispred#ff ON FIRST 1 OUTPUT Lhs.1, Lhs.0 'arg2', Rhs.1 'arg1'
                      561015756 ~1%     {3} r2 = JOIN r1 WITH Variable::variableName#ff_10#join_rhs ON FIRST 1 OUTPUT Rhs.1 'arg0', Lhs.2 'arg1', Lhs.1 'arg2'
                                        return r2
```

This change ensures that we join on name and scope simultaneously.

c5904b7410 Add inline tests for API Graph subclassing 2022-01-25 16:41:49 +13:00
Harry Maclean
517f2d0823 Add optional results to InlineExpectationsTest 
The idea behind optional results is that there may be instances where
each line of source code has many results and you don't want to annotate
all of them, but you still want to ensure that any annotations you do
have are correct.

This change makes that possible by exposing a new predicate
`hasOptionalResult`, which has the same signature as `hasResult`.

Results produced by `hasOptionalResult` will be matched against any
annotations, but the lack of a matching annotation will not cause a
failure.

We will use this in the inline tests for the API edge getASubclass,
because for each API path that uses getASubclass there is always a
shorter path that does not use it, and thus we can't use the normal
shortest-path matching approach that works for other API Graph tests.
