Domenic Denicola	7afdba6e0b	vm, core, module: re-do vm to fix known issues As documented in #3042 and in [1], the existing vm implementation has many problems. All of these are solved by @brianmcd's [contextify][2] package. This commit uses contextify as a conceptual base and its code core to overhaul the vm module and fix its many edge cases and caveats. Functionally, this fixes #3042. In particular: - A context is now indistinguishable from the object it is based on (the "sandbox"). A context is simply a sandbox that has been marked by the vm module, via `vm.createContext`, with special internal information that allows scripts to be run inside of it. - Consequently, items added to the context from anywhere are immediately visible to all code that can access that context, both inside and outside the virtual machine. This commit also smooths over the API very slightly: - Parameter defaults are now uniformly triggered via `undefined`, per ES6 semantics and previous discussion at [3]. - Several undocumented and problematic features have been removed, e.g. the conflation of `vm.Script` with `vm` itself, and the fact that `Script` instances also had all static `vm` methods. The API is now exactly as documented (although arguably the existence of the `vm.Script` export is not yet documented, just the `Script` class itself). In terms of implementation, this replaces node_script.cc with node_contextify.cc, which is derived originally from [4] (see [5]) but has since undergone extensive modifications and iterations to expose the most useful C++ API and use the coding conventions and utilities of Node core. The bindings exposed by `process.binding('contextify')` (node_contextify.cc) replace those formerly exposed by `process.binding('evals')` (node_script.cc). They are: - ContextifyScript(code, [filename]), with methods: - runInThisContext() - runInContext(sandbox, [timeout]) - makeContext(sandbox) From this, the vm.js file builds the entire documented vm module API. node.js and module.js were modified to use this new native binding, or the vm module itself where possible. This introduces an extra line or two into the stack traces of module compilation (and thus into most stack traces), explaining the changed tests. The tests were also updated slightly, with all vm-related simple tests consolidated as test/simple/test-vm-* (some of them were formerly test/simple/test-script-*). At the same time they switched from `common.debug` to `console.error` and were updated to use `assert.throws` instead of rolling their own error-testing methods. New tests were also added, of course, demonstrating the new capabilities and fixes.

elliottcable	200df8641b	Fix #1801 vm: Use 'sandbox' as global_prototype Squashed commit: (- re tests) Cleaning up the `Script` test suite. For whatever reason, there were several duplicate test files related to `Script` and the `'vm'` module. I removed these, and fixed a few other small issues. (More fixes coming in subsequent commits.) Squashes: 19e86045a0..1e3dcff4eb (api fix:1801 new:1801) `'vm'` module uses sandbox as prototype As described in GH-1801, the `'vm'` module was handling the `sandbox` object provided by the API consumer in a particularly terrible and fragile fashion: it was simply shallow-copying any enumerable properties from the sandbox onto the global context before executing the code, and then eventually copying any values on the global context back into the sandbox object afterwards. This commit removes all of that implementation, and utilizes the passed sandbox object as the prototype of the context instead. A bit of a hack, but a very effective one. This no longer allows for new variables created in the global context to be placed into your sandbox after execution has completed, but that’s for the best anyway, as it’s not very in line with the concept of a “box of passed-in context.” I’m planning to further implement an interface for API consumers to acquire the actual global from within the VM soon, thus allowing for separation-of-concerns: providing data to the VM via the sandbox-prototype, and exploring the internal environment of the VM itself. // GitHub cruft: closes #1801 Squashes: 43b8e3c..209ed86	13 years ago
