f5f84c7625 Fix for*/fold and for*/lists 
Only parse and use the type annotations if they are present on
all fold variables. This matches the default for other forms in TR.
Also, this will usually result in a "insufficient type information"
message which is more helpful than if TR chose some default type.

2e97280335 Eliminate the eval hack for top-level structs 
This eliminates a hack used to make the `struct` form

e031d6c47e Typecheck the top-level using trampolining macros 
Instead of local-expanding the entire top-level forms at
once, wrap expressions in a top-level begin in trampolining
macro forms. This allows the typechecker to trampoline back
to the evaluator, which is necessary to declare/register
declarations made in a top-level begin.

The point of this change is to eliminate top-level hacks
and faciliate various macros that need to communicate using
multiple top-level forms.

e997f02095 Rewrite compound pair operation optimization. 
Previous version replaced calls to, e.g., `cadr` with calls to `cdr`
then `car`, called the typechecker to populate the type table, then
optimized the exploded operations. The call to the typechecker failed
on open terms, limiting the applicability of the optimization, and was
just generally brittle.

The new version instead explodes operations, then optimizes them inside
out for as long as the argument's type guarantees it's safe. This works
on open terms, and should be more robust.

29144c7932 Fix handling of let rhs that don't return 
In the case that a let rhs doesn't return and therefore the
bodies of the let are unreachable, the bodies need to be marked
as ignored for the optimizer.

In addition, don't attempt unboxed let optimization at all
if the return type is Nothing since it probably means some
body expressions have no type.

6512b52b1d Fix polymorphic recursion check for type aliases 
The old check was broken for cases with type constructors
with more than one type argument and was also too conservative
in some cases (e.g., when one cycle refers to another cycle of
 aliases in a non-recursive manner).

The new check is still conservative, but it allows more types
than before.

577b5225cd Fix construction of promise contracts; broken in 5cd5f772. 2015-07-22 16:29:39 -04:00
Sam Tobin-Hochstadt
5cd5f772d6 Don't allow promises created with delay/name as (Promise T). 
Since these promises re-evaluate their bodies every time they
are forced, allowing them makes `force` not idempotent and not
safe to treat as a path.

This change is slightly backwards-incompatible, since programs
that previously passed `delay/name` promises across the typed
boundary will now fail at runtime. The alternative is also
incompatible: stop treating `force` as a path. Since `delay/name`
is quite obscure, this approach seems like the safer choice.

1842aaa2bd fixes for some tests 
The `identifier-binding` function is now senstive to the "macro
introduction" scope that's on an indentifier provided to a currently
expanding macro. Unit tests for TR need to use
`syntax-local-intorduce` to remove it, in the same way that `tc-setup`
already does.

Also, recognize a class expansion when it's wrapped with
`#%expression`, since `class` now expands that way sometimes.

2d095c4112 adapt to letrec-syntaxes+values removal and quote-syntax extension 
The `quote-syntax` form now suports a `#:local` option, which is
used for type annotations to preserve binding context.

Since `letrec-syntaxes+values` is now removed by `local-expand`,
some patterns must be adjusted, including the pattern used
for type annotations.

2f00de99d0 declare empty namespace for submodules 
Using the enclosing module's context for the `#f` part of the
`(module* _ #f ....)` would generally enable a compact encoding of
bindings for the purposes of `module->namespace`. Disabling
`module->namespace` for the generated submodules seems more reliable,
and it seems unlikely that anyone will miss the extra debugging
capability (which is all that is lost for these submodules whose
content is, I think, unspecified).

609d6189e9 Improve typecheck for private field initializers 
This patch addresses two issues with `typed/racket/class`:

1. For multiple private fields declared with `define-values`, type
information does not propagate from the values produced by the
initialization expression to the declared fields. This breaks soundness
of private fields: A field can be annotated with a type that does not
contain the field's initial value.

This was resolved by keeping a table of temporary bindings introduced in
the expansion of the initializer along with their types. The field
setter's type is then checked against that of the corresponding
temporary.

2. The class body typechecker assumes that the `expr` of
a `define-values` clause will expand to a bare `(values vs ...)`.

This was resolved by generalizing the template for matching an expanded
`define-values` initializer and extracting the type information from the
`expr` instead of each element in `(vs ...)`.

as the whole file, to ~100ms. For comparison, `racket/base` is 30ms
and `#lang racket` is 150ms. `#lang typed/racket` is ~200ms with
this change.

Changes include:
 - not using `in-syntax`
 - switching to `syntax/parse/pre`
 - avoiding `template` from `syntax/parse`

c70910aaa0 Fix type restriction in values->tc-results 
Previously the restriction didn't account for traversing
the object type with the given path. This also relies on
the previous commit that adds subtyping on filters.

(because this change seems to introduce filters which
 only differ by an unrolling of a recursive type, but
 the old subtyping only worked for identical types)

8acc86bb9b Add subtyping for types inside filters 
This makes a type like

  (-> Any Boolean : #:+ Integer)

a subtype of a type like

  (-> Any Boolean : #:+ Number)

For not filters, the direction is reversed.

ae0717d970 Move generated contracted provides to a submodule. 
This allows the main TR module not to explicitly
depend on the contract library. Each exported name
can be redirected to either the original name (for a
typed client) or to another macro (for an untyped
client) which expands to a `local-require` for the
relevant submodule (named `#%contract-defs`).

implementation in plai-typed that this is based on.
