Subject: Some proposed modifications of CarrierClass
Message-ID: <76986489.1846861.1636159912839.JavaMail.zimbra@u-pem.fr>

Hi Jim,
I've taken a look to the Carrier class.

Here are some small modifications,
- the computation of max locals/max stack for the constructor.
- use hidden class instead of classical class.
- use the Lookup of the hidden class instead of using reflection to get the constructor and the array of components.
- store the constructors and the components in the CarrierClass to avoid to recompute them at each call.

Obviously, feel free to use whatever parts you want.

regards,
R?mi

 switch (Second Preview)

Message-ID: <c705c195-328a-a33e-f1cb-9e8bf9aed5bf@oracle.com>

This is more of a spec issue than a compiler issue.? I finally got 
around to running some of my favorite GADT examples on this.

I started with this Haskell type:

 ??? data Term t where
 ??????? Lit :: t -> Term t
 ??????? Succ :: Term Int -> Term Int
 ??????? IsZero :: Term Int -> Term Bool
 ??????? If :: Term Bool -> Term a -> Term a -> Term a

I can map it to this Java hierarchy:

 ??? sealed interface Term<T> { }

 ??? record Lit<T>(T val) implements Term<T> { }
 ??? record Succ(Term<Integer> a) implements Term<Integer> { }
 ??? record IsZero(Term<Integer> a) implements Term<Boolean> { }
 ??? record If<T>(Term<Boolean> cond, Term<T> a, Term<T> b) implements 
Term<T> { }

We correctly eliminate the impossible cases in:

 ??? String foo(Term<String> t) {
 ? ?? ?? return switch (t) {
 ??????????? case Lit<String> -> "Lit";
 ??????????? case If<String> -> "If";
 ??????? }
 ??? }

And the compiler correctly tells me that the switch is exhaustive.? But 
if I try to write an evaluator:

 ??? static<T> T eval(Term<T> term) {
 ??????? return switch (term) {
 ??????? case Lit<T> t -> t.val;
 ??????? case Succ t -> eval(t.a) + 1;
 ??????? case IsZero t -> eval(t.a) == 0;
 ??????? case If<T> t -> eval(t.cond) ? eval(t.a) : eval(t.b);
 ??????? };
 ??? }


I get errors on the Succ and IsZero cases.? In Haskell, the equivalent:

 ??? eval :: Term t -> t
 ??? eval (Lit t) = t
 ??? eval (Succ i) = (eval i) + 1
 ??? ...

works correctly because when we match on `eval (Succ i)`, we unify t 
with Int, since that's the only instantiation for t that would work in 
this case.? That's what allows us to return an Int when we're expecting 
a t, because we've already figured out they are the same.

So in order to make our eval work, we would have to know to _refine_ the 
bounds of T on the RHS of

 ??????? case Succ t -> eval(t.a) + 1;

where we would say "Succ is Term<T>, and Succ extends Term<Integer>, so 
T=Integer here".

In the absence of this, I have to do an explicit boxing plus an 
unchecked cast:

 ??? static<T> T eval(Term<T> term) {
 ??????? return switch (term) {
 ??????? case Lit<T> t -> t.val;
 ??????? case Succ t -> (T) (Integer) (eval(t.a) + 1);
 ??????? case IsZero t -> (T) (Boolean) (eval(t.a) == 0);
 ??????? case If<T> t -> eval(t.cond) ? eval(t.a) : eval(t.b);
 ??????? };
 ??? }

That we need both the boxing and the T cast is probably a bug.

The updated specification excludes such impossible permitted subclasses from exhaustiveness checks, so the default is no longer needed and this:

Hi,


Regarding GADT semantics, I would also like to see empty switches, which is an inevitable phenomenon when you can refute patterns. Is empty switch a thing yet?

This is more of a spec issue than a compiler issue.&nbsp; I finally got 
around to running some of my favorite GADT examples on this.

I started with this Haskell type:

&nbsp;&nbsp;&nbsp;&nbsp; data Term t where
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Lit :: t -&gt; Term t
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Succ :: Term Int -&gt; Term Int
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; IsZero :: Term Int -&gt; Term Bool
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If :: Term Bool -&gt; Term a -&gt; Term a -&gt; Term a

I can map it to this Java hierarchy:

&nbsp;&nbsp;&nbsp;&nbsp; sealed interface Term<T&gt; { }

&nbsp;&nbsp;&nbsp;&nbsp; record Lit<T&gt;(T val) implements Term<T&gt; { }
&nbsp;&nbsp;&nbsp;&nbsp; record Succ(Term<Integer&gt; a) implements Term<Integer&gt; { }
&nbsp;&nbsp;&nbsp;&nbsp; record IsZero(Term<Integer&gt; a) implements Term<Boolean&gt; { }
&nbsp;&nbsp;&nbsp;&nbsp; record If<T&gt;(Term<Boolean&gt; cond, Term<T&gt; a, Term<T&gt; b) implements 
Term<T&gt; { }

We correctly eliminate the impossible cases in:

&nbsp;&nbsp;&nbsp;&nbsp; String foo(Term<String&gt; t) {
&nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; return switch (t) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case Lit<String&gt; -&gt; "Lit";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case If<String&gt; -&gt; "If";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp;&nbsp; }

And the compiler correctly tells me that the switch is exhaustive.&nbsp; But 
if I try to write an evaluator:

&nbsp;&nbsp;&nbsp;&nbsp; static<T&gt; T eval(Term<T&gt; term) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return switch (term) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case Lit<T&gt; t -&gt; t.val;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case Succ t -&gt; eval(t.a) + 1;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case IsZero t -&gt; eval(t.a) == 0;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case If<T&gt; t -&gt; eval(t.cond) ? eval(t.a) : eval(t.b);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; };
&nbsp;&nbsp;&nbsp;&nbsp; }


I get errors on the Succ and IsZero cases.&nbsp; In Haskell, the equivalent:

&nbsp;&nbsp;&nbsp;&nbsp; eval :: Term t -&gt; t
&nbsp;&nbsp;&nbsp;&nbsp; eval (Lit t) = t
&nbsp;&nbsp;&nbsp;&nbsp; eval (Succ i) = (eval i) + 1
&nbsp;&nbsp;&nbsp;&nbsp; ...

works correctly because when we match on `eval (Succ i)`, we unify t 
with Int, since that's the only instantiation for t that would work in 
this case.&nbsp; That's what allows us to return an Int when we're expecting 
a t, because we've already figured out they are the same.

So in order to make our eval work, we would have to know to _refine_ the 
bounds of T on the RHS of

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case Succ t -&gt; eval(t.a) + 1;

where we would say "Succ is Term<T&gt;, and Succ extends Term<Integer&gt;, so 
T=Integer here".

In the absence of this, I have to do an explicit boxing plus an 
unchecked cast:

&nbsp;&nbsp;&nbsp;&nbsp; static<T&gt; T eval(Term<T&gt; term) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return switch (term) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case Lit<T&gt; t -&gt; t.val;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case Succ t -&gt; (T) (Integer) (eval(t.a) + 1);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case IsZero t -&gt; (T) (Boolean) (eval(t.a) == 0);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case If<T&gt; t -&gt; eval(t.cond) ? eval(t.a) : eval(t.b);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; };
&nbsp;&nbsp;&nbsp;&nbsp; }

That we need both the boxing and the T cast is probably a bug.

Do you mean switches that have no operand, so the cases are a series of 
guards, or a switch with no cases?? The latter seems unlikely since the 
cases of a switch must be exhaustive on the type of the operand.

Hi,




I meant the latter. Consider Term<T&gt; with Lit and If, two subclasses removed, and you switch on an instance of Term<String&gt;.

         This is more of a spec issue than a compiler issue.&nbsp; I finally         got 
         around to running some of my favorite GADT examples on this.
         
         I started with this Haskell type:
         
         &nbsp;&nbsp; &nbsp; data Term t where
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; Lit :: t -&gt; Term t
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; Succ :: Term Int -&gt; Term Int
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; IsZero :: Term Int -&gt; Term Bool
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; If :: Term Bool -&gt; Term a -&gt; Term a -&gt; Term a
         
         I can map it to this Java hierarchy:
         
         &nbsp;&nbsp; &nbsp; sealed interface Term<T&gt; { }
         
         &nbsp;&nbsp; &nbsp; record Lit<T&gt;(T val) implements Term<T&gt; { }
         &nbsp;&nbsp; &nbsp; record Succ(Term<Integer&gt; a) implements         Term<Integer&gt; { }
         &nbsp;&nbsp; &nbsp; record IsZero(Term<Integer&gt; a) implements         Term<Boolean&gt; { }
         &nbsp;&nbsp; &nbsp; record If<T&gt;(Term<Boolean&gt; cond, Term<T&gt;         a, Term<T&gt; b) implements 
         Term<T&gt; { }
         
         We correctly eliminate the impossible cases in:
         
         &nbsp;&nbsp; &nbsp; String foo(Term<String&gt; t) {
         &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; return switch (t) {
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; case Lit<String&gt; -&gt; "Lit";
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; case If<String&gt; -&gt; "If";
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; }
         &nbsp;&nbsp; &nbsp; }
         
         And the compiler correctly tells me that the switch is         exhaustive.&nbsp; But 
         if I try to write an evaluator:
         
         &nbsp;&nbsp; &nbsp; static<T&gt; T eval(Term<T&gt; term) {
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; return switch (term) {
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; case Lit<T&gt; t -&gt; t.val;
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; case Succ t -&gt; eval(t.a) + 1;
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; case IsZero t -&gt; eval(t.a) == 0;
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; case If<T&gt; t -&gt; eval(t.cond) ? eval(t.a) :         eval(t.b);
         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; };

Hi all,

My friend Kiva have discovered an ICE of javac 17, here's the reproduction:


```
class Scratch {
&nbsp; public static void main(String[] args) {
&nbsp; &nbsp; switch (null) {
&nbsp; &nbsp; &nbsp; case null -&gt; System.out.println("114");
&nbsp; &nbsp; &nbsp; default -&gt; System.out.println("514");
&nbsp; &nbsp; }
&nbsp; }
}
```


FYI the following code compiles:


```
class Scratch {
&nbsp; public static void main(String[] args) {
&nbsp; &nbsp; var x = (Object) null;
&nbsp; &nbsp; switch (x) {
&nbsp; &nbsp; &nbsp; case null -&gt; System.out.println("1919");
&nbsp; &nbsp; &nbsp; default -&gt; System.out.println("810");
&nbsp; &nbsp; }
&nbsp; }
}
```



I have no idea how to file a bug to openjdk, so I'm just posting it here.


Best regards,
Tesla

Hi,

This is a known issue. It was solved at JDK18 and was backported to
JDK17.0.2. Please see this bug description[1].

You can use JDK18 early access builds[2] to avoid this issue or wait
JDK17.0.2 to release.

Best Regards,

Hi all,


In jep420, I saw




Without such pattern matching, expressing ad-hoc polymorphic calculations like this requires using the cumbersome [visitor pattern][visitor]. Pattern matching is generally more transparent and straightforward.




Probably a link label is missing

Hi,

I'm very happy to see that 420 is now targeting JDK 18, but what about 405? Is it planned to be launched in JDK 18?


Best regards,

Subject: Final variable initialization problem with exhaustive switch
Message-ID: <CAMg+uVR0ZQz2GLXDcM99YivriJ4Mj9vQ5SBy8AbB6pjyxuCyVg@mail.gmail.com>

Consider the case:

enum Parity {ODD, EVEN}
Parity p = ...
final int a;
switch (p) {
    case Parity.ODD -> a = 1;
    case Parity.EVEN -> a = 0;
}
int b = a + 1; //Compile time error: variable a might not have been
initialized

The switch is exhaustive, yet we need to add a default case to compile. The
same behaviour is observed with instance final fields too.
Without changing the semantics, the code below compiles:

final int a = switch (p) {
    case Parity.ODD -> 1;
    case Parity.EVEN -> 0;
};
int b = a + 1; //Compiles

How can the compiler prove that the final variable will be initialized only
in the second case and not in the first too?

Thanks for your time.

Subject: Switch on sealed enums
Message-ID: <AS8PR02MB65653A11E9F029B9549786A7E9619@AS8PR02MB6565.eurprd02.prod.outlook.com>

I've played around with sealed interfaces implemented by multiple enums only, and I've found some inconveniences I wanted to share here.

Consider the following class hierarchy:

    sealed interface Token {
        enum Digit implements Token { ONE, TWO, THREE }
        enum Letter implements Token { A, B, C }
    }

I can use a nested switch expression to cover all cases:

    static String toStringNested(Token token) {
        return switch (token) {
            case Digit d -> switch (d) {
                case ONE -> "1";
                case TWO -> "2";
                case THREE -> "3";
            };
            case Letter l -> switch (l) {
                case A -> "A";
                case B -> "B";
                case C -> "C";
            };
        };
    }

I thought that in theory, I should be able to use a single, flattened switch that covers all digits and all letters:

    static String toStringFlat(Token token) {
        return switch (token) {
            case ONE -> "1";
            case TWO -> "2";
            case THREE -> "3";
            case A -> "A";
            case B -> "B";
            case C -> "C";
        };
    }

This is probably deliberately not supported (yet). Anyway, here are my findings:

1. The compiler requires that the enum constants be unqualified.
But since we have multiple enums here, just leaving the enum away doesn't work either; we need to add static imports:

    import static package.to.Token.Digit.*;
    import static package.to.Token.Letter.*;

2. The compiler cannot figure out that the switch is exhaustive, even if we do cover all cases.
We need to add a default case to fix this compiler error.

3. With the default case added, the code still doesn't compile (my IDE thinks it does);
We get an error "constant expression required" for each case.


In case you wonder why one would use sealed hierarchies of enums, it probably makes more sense to think about these
as "enums with subgroups". Using this approach, you can model more precisely that a method accepts or returns only a subset
of the cases, but a logical coherent subset.
One special reason of grouping enum constants is the use of generics: we could extend our hierarchy as follows:

    sealed interface Token<T> {
        T value();
        enum Digit implements Token<Integer> {
            ONE, TWO, THREE;
            @Override public Integer value() { ... }
        }
        enum Letter implements Token<Character> {
            A, B, C;
            @Override public Character value() { ... }
        }
    }

This could also be seen as a workaround for JEP 301: "Enhanced Enums", but a very good one in my opinion.
Only when every enum constant needs a different type argument (as in the JEP's examples), you would need to wrap each constant
in its own enum.

Overall, I think there are good places for such groupings of enums. And it would help if they could be used just like a single enum inside
switch.


Cheers,
Matthias Perktold

That differing treatment of definite assignment seems like
it should be a bug, right?  But it?s not.  In fact, your switch
expression can (under certain circumstances) execute
correctly without executing either of its case branches.

Switch expressions are inherently exhaustive across their cases.
Switch statements are not.  This is a key difference.

You can see this if you take your code and comment out
one of the cases, say for Parity.EVEN.  The switch expression
errors out at compile time, but the switch statement is a
happy camper.

Or, if someone comes along and adds a third member to Parity
(say, NEITHER) then your switch expression will either fail to
compile statically or (if not recompiled) will fail to terminate
normally at runtime (throwing something).

Meanwhile, the corresponding switch statement will happily
recompile, and (whether recompiled or not) will fall through
when Parity.NEITHER is presented.  In that case, the variable
in question will not have been initialized.

This is a problem with legacy switch statements.  I?m not sure
what the solution will be, although I know various alternatives
have been discussed at some point.  The problem is that the
language cannot read the user?s mind, when it finds that
(a) an enum is the subject of a switch statement but (b) not
all members of the enum are mentioned in the cases.  Is it
an error in a switch that was intended to be exhaustive?
Or is it just that the user (that lazy user!) didn?t want to
mention cases which needed no-op actions?

Agree, it is just playing it too safe.

We can translate the above switch statement into an if, without losing the
semantics:

if (p == Parity.ODD) {
    a = 1;
} else if (p == Parity.EVEN) {
    a = 0;
}
int b = a + 1; //Compile time error: variable a might not have been
initialized

The above if is exhaustive, yet no one expects last statement to compile,
and that is totally fine.
So, reducing the switch to the above if, makes it clear why the compiler
can't guarantee about the switch too.
But, maybe it should. You see, to let the above if compile is an overkill,
but with the switch, we have the notion
of its context, and especially with enums and sealed types, we can take it
a step further and make assumptions
about its exhaustiveness.

The switch expression guarantees initialization of final variables, based
on whether it compiles or not, which by
itself depends on its exhaustiveness.
The switch statement does not have to be exhaustive to compile and
therefore there isn't here that compilation
barrier that guarantees the initialization. But, that doesn't have to be
the case. Our switch statement in question
is *Effectively *exhaustive. So, the compiler doesn't need to prove that a
switch statement is exhaustive, it is
sufficient to just prove that it is effectively exhaustive. It is similar
to the effectively final variables we have with
lambdas.

Of Course, at the end of the day, it's not about exhaustiveness, it's about
having a branch that is guaranteed
to perform the initialization. That is what we are effectively trying to
prove.

Lately, the switch has been greatly enhanced, especially in the
exhaustiveness department. Getting the
switch statement on track in that aspect, seems more consistent.

This is a sensible-seeming and well-intentioned argument, but it is unfortunately not correct.  

The problem is one of separate compilation.  At compile time, there are only two enum constants, EVEN and ODD, but at run time, there may be more (someone could edit Parity to add INDETERMINATE, and not recompile the client code.)  If such a novel constant shows up at runtime, the program semantics are subverted.  

Combine this with the fact that historically, switch statements are inherently partial; the switch you wrote currently *has a meaning*, which is if a novel value shows up, do neither of the actions.  This might be a ?dumb? meaning, but it is the meaning existing switches have, and we can?t arbitrarily change it.  

What you are arguing is that we made bad decisions in 1995 by allowing partial switches at all; while I might agree with that, in hindsight, it was ?obvious? in 1995 that partiality was an inherent aspect of switch statements (because, C.)  When we added switch *expressions*, totality was a forced move (and a good one); when we extended switches to support patterns, we made the bold move (which will annoy some) to require that non-legacy switch STATEMENTS also be total.  But we can?t rewrite history.  

We toyed with the idea of having a modifier on switch (e.g. ?total-switch?) which would engage the totality checking, but the return here seemed weak; it would only work if people changed their code.   We could over a decade possibly nudge pattern switches towards totality, with a gradually increasing set of warnings which eventually became errors, and we might do that, but let?s not kid ourselves that this is a very long road.  

We are largely in a no-win situation; we can either have newer constructs inherit the mistakes of the past, or live with some seam of ?old? switches working slightly differently.  We can try to move that seam around, but its hard to have it all.  Your claim of ?inconsistency? illustrates that fact, but if you had consistency, you wouldn?t like it, because we?d have to be consistent with the bad old behavior.  

Of course, whether this is ?too? safe is a matter of opinion.  It is a popular viewpoint to say ?but its wrong, just go ahead and break other people?s code, its good for them.?  But people won?t thank you for educating them; not doing so (or doing so only very, very carefully) is how Java stays popular.  So while I might call it unfortunate, it?s not ?too? safe; its just safe.

It's a long road but any stations along that road is a better place than the one we are currently.

Dimitris send me the code privately before and ask me if it was a bug or not.
I answer that it was a bug, I was wrong. I'm pretty sure Dimitris and me are not the only ones to fall into that trap.

Adding a warning requiring a default might be a good step forward, even if we never do more than that.

Fortunately, a warning does not break the code.
