52f2a9a1c9 Test case to make sure typestate checks the body of class constructors 2012-03-28 10:38:57 -07:00

edb747ceed Enforce mutability declarations in classes; correct shapes for classes 
1. Enforce mutability declarations on class fields. Don't allow any
mutation of class fields not declared as mutable (except inside the
constructor).

2. Handle classes correctly in shape (treat classes like records).

the private method you were trying to call was in the same crate

67cc89f38d Rewrite exhaustiveness checker 
Issue #352
Closes #1720

The old checker would happily accept things like 'alt x { @some(a) { a } }'.
It now properly descends into patterns, checks exhaustiveness of booleans,
and complains when number/string patterns aren't exhaustive.

e5d095d67e Change option::t to option 
Now that core exports "option" as a synonym for option::t, search-and-
replace option::t with option.

The only place that still refers to option::t are the modules in libcore
that use option, because fixing this requires a new snapshot
(forthcoming).

888262b337 Allow operator overloading of the indexing operator

87b064b249 First stab at operator overloading 
When no built-in interpretation is found for one of the operators
mentioned below, the typechecker will try to turn it into a method
call with the name written next to it. For binary operators, the
method will be called on the LHS with the RHS as only parameter.

Binary:

    +   op_add
    -   op_sub
    *   op_mul
    /   op_div
    %   op_rem
    &   op_and
    |   op_or
    ^   op_xor
    <<  op_shift_left
    >>  op_shift_right
    >>> op_ashift_right

Unary:

    -   op_neg
    !   op_not

Overloading of the indexing ([]) operator isn't finished yet.

6db688e893 Check that the names mentioned in tag exports are actually types (or variants) 
Check that in export foo{}, foo is an enum type, and that in export

9dc59e1506 Export all enum variants by default; new syntax for selectively exporting variants 
See issue 1426 for details. Now, the semantics of "export t;" where t is a tag are
to export all of t's variants as well. "export t{};" exports t but not its
variants, while "export t{a, b, c};" exports only variants a, b, c of t.

To do:
- documentation
- there's currently no checking that a, b, c are actually variants of t in the
 above example
- there's also no checking that t is an enum type, in the second two examples above
- change the modules listed in issue 1426 that should have the old export
semantics to use the t{} syntax

I deleted the test export-no-tag-variants since we're doing the opposite now,
and other tests cover the same behavior.

e36df0f6c8 Handle fail after return correctly in typestate 
Previously, typestate would conclude that this function was
correctly diverging:

fn f() -> ! { ret; fail; }

even though it always returns to the caller. It wasn't handling the
i_diverge and i_return bits correctly in the fail case. Fixed it.
