           Summary: JSStaticFunction and JSStaticValue are overly "const"
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified

          Severity: Minor
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org

* SUMMARY

JSStaticFunction has this definition:

typedef struct {
    const char* const name; // FIXME: convert UTF8
    JSObjectCallAsFunctionCallback callAsFunction;
    JSPropertyAttributes attributes;
} JSStaticFunction;

which means that it's impossible to initialize the name field dynamically. E.g. this code:

JSStaticFunction *fun;
fun->name = "something";

fails with a compiler error. There is no reason for the second of those two "const" qualifiers? A cast will be needed to set the structure field..

[...]


it definitely gives a warning for me, in test.c:

#include <JavaScriptCore/JavaScriptCore.h>
static void foo (void)
{
    JSStaticFunction *fun;
    fun->name = "something";
}

then:

$ cc -c test.c
test.c: In function 'foo':
test.c:7: error: assignment of read-only member 'name'

in my actual code I did this:

*(void **)&funptr->name = (void *) m->desc->jsName;
