2019-07-22src: make `CompiledFnEntry` a `BaseObject`Anna Henningsen
In particular: - Move the class definition to the relevant header file, i.e. `node_contextify.h`. - Make sure that class instances are destroyed on `Environment` teardown. - Make instances of the key object traceable in heap dumps. This is particularly relevant here because our C++ script → map key mapping could introduce memory leaks when the import function metadata refers back to the script in some way.

2019-04-30src: prefer v8::Global over node::PersistentAnna Henningsen
`v8::Global` is essentially a nicer variant of `node::Persistent` that, in addition to reset-on-destroy, also implements move semantics. This commit makes the necessary replacements, removes `node::Persistent` and (now-)unnecessary inclusions of the `node_persistent.h` header, and makes some of the functions that take Persistents as arguments more generic so that they work with all `v8::PersistentBase` flavours.

2013-08-21vm, core, module: re-do vm to fix known issuesDomenic Denicola
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.
