Bug 1544834 - Replace deprecated generics in test code r=evilpie - `Array.map` becomes `Array.from` - Array copying via `Array.slice` becomes `Array.from`. - `Array.forEach` that did not rely on closures becomes `for`-`of` loops. - Anything else: `Array.X` becomes `Array.prototype.X`. Complex cases: dom/bindings/test/TestInterfaceJS.js and dom/bindings/test/test_exception_options_from_jsimplemented.html use `Array.indexOf` to generate an error with a specific error message. Switched to `Array.prototype.forEach` to generate the same error. js/src/jit-test/tests/basic/exception-column-number.js In this test `Array.indexOf()` is used to generate an error. Since the exact message doesn't matter, I switched to `Array.from()`. Intentionally not changed: editor/libeditor/tests/browserscope/lib/richtext/richtext/js/range.js Did not modify because this is 3rd-party code and the code uses feature detection as a fall back when Array generics are not used. testing/talos/talos/tests/dromaeo/lib/mootools.js Did not modify because mootools adds the `Array.slice` method to the `Array` object. Not changed because they check the implementation of Array generics: js/src/jit-test/tests/basic/arrayNatives.js js/src/jit-test/tests/basic/bug563243.js js/src/jit-test/tests/basic/bug618853.js js/src/jit-test/tests/basic/bug830967.js js/src/jit-test/tests/jaeger/recompile/bug656753.js js/src/jit-test/tests/self-hosting/alternate-static-and-instance-array-extras.js js/src/tests/non262/Array/generics.js js/src/tests/non262/Array/regress-415540.js js/src/tests/non262/extensions/regress-355497.js js/src/tests/non262/extensions/typedarray-set-neutering.js Depends on D27802 Differential Revision: https://phabricator.services.mozilla.com/D27803

Bug 1544834 - Replace non-test uses of deprecated Array generics r=evilpie,dao - `Array.forEach` becomes for-of loop or `array.forEach`. - `Array.slice(a)` or `Array.slice(a, 0)` becomes `Array.from(a)`. - `Array.map` becomes `Array.from` - `Array` copy + concatenation becomes Array literal + spread syntax. - All other `Array.X(a, ...)` become `Array.prototype.X.call` or `Array.from(a).X(...)` Differential Revision: https://phabricator.services.mozilla.com/D27802

Bug 1521677. Change defineProperties to handle non-configurable properties on WindowProxy like defineProperty does. r=evilpie We want to indicate "we didn't actually manage to define your properties as non-configurable" but we don't want to throw exceptions when people try to Object.defineProperties with a non-configurable property in the list on a WindowProxy. Though maybe we should just silently ignore the "can't define non-configurable on WindowProxy" bits in defineProperties and just return the object anyway? The reason we do the "return null" bit in defineProperty is so that Caja and the like can detect it, but if they're not using defineProperties to start with they may not need to detect this "failure". On the other hand, Mark Miller thinks the detection will be needed... Differential Revision: https://phabricator.services.mozilla.com/D17516

Bug 859782 - Firefox cannot start without /proc (chroot). r=sfink,evilpie,jld Firefox uses the current stack frame address and the stack size as a sort of heuristic for various things in the javascript engine. The js::GetNativeStackBaseImpl() function is used to get the base stack address (ie the address from which the stack grows, so this can be either the first or last memory address of the stack memory space depending on the CPU architecture). On Linux, this function is implemented using the pthreads APIs. For non-main threads, the queried thread info is stored in memory. The main thread does not have this information on hand, so it gets the stack memory range via the /proc/self/maps file ( see glibc's pthread_get_attr_np.c ). Fortunately (per discussions with the firefox devs in #jsapi) the base address only needs to be approximation. In reality, environment variables, args, and other things are stored in space between the end/beginning of the mapped stack memory and the 'top' of the stack space used by stack frames. We can get the top of this usable stack from __libc_stack_end, which is a void* set by glibc during program initialization. Non-main threads still get their stack-base through the usual pthreads APIs.
