Ben Noordhuis	9ff7ed23cd	lib: fix event race condition with -e Commit `c5b07d4` ("lib: fix beforeExit not working with -e") runs the to-be-evaluated code at a later time than before because it switches from `process.nextTick()` to `setImmediate()`. It affects `-e 'process.on("message", ...)'` because there is now a larger time gap between startup and attaching the event listener, increasing the chances of missing early messages. I'm reasonably sure `process.nextTick()` was also susceptible to that, only less pronounced. Avoid the problem altogether by evaluating the code synchronously. Harmonizes the logic with `Module.runMain()` from lib/module.js which also calls `process._tickCallback()` afterwards.

Ben Noordhuis	c5b07d4ec6	lib: fix beforeExit not working with -e Commit `93a44d5` ("src: fix deferred events not working with -e") defers evaluation of the script to the next tick. A side effect of that change is that 'beforeExit' listeners run before the actual script. 'beforeExit' is emitted when the event loop is empty but process.nextTick() does not ref the event loop. Fix that by using setImmediate(). Because it is implemented in terms of a uv_check_t handle, it interacts with the event loop properly.

Anna Henningsen	0815b9401d	vm: add ability to break on sigint/ctrl+c - Adds the `breakEvalOnSigint` option to `vm.runIn(This)Context`. This uses a watchdog thread to wait for SIGINT and generally works just like the existing `timeout` option. - Adds a method to the existing timer-based watchdog to check if it stopped regularly or by running into the timeout. This is used to tell a SIGINT abort from a timer-based one. - Adds (internal) `process._{start,stop}SigintWatchdog` methods to start/stop the watchdog thread used by the above option manually. This will be used in the REPL to set up SIGINT handling before entering terminal raw mode, so that there is no time window in which Ctrl+C fully aborts the process.

Ruben Bridgewater	88307974e6	node: improve process.nextTick performance Prevent deoptimization of process.nextTick by removing the try finally block. This is not necessary as the next tick queue will be reset anyway, no matter if the callback throws or not. Use a predefined array size prevents resizing the array and is therefor faster.

Ben Noordhuis	70d1f32f56	deps: update v8 to 4.4.63.9 Upgrade the bundled V8 and update code in src/ and lib/ to the new API. Notable backwards incompatible changes are the removal of the smalloc module and dropped support for CESU-8 decoding. CESU-8 support can be brought back if necessary by doing UTF-8 decoding ourselves. This commit includes https://codereview.chromium.org/1192973004 to fix a build error on python 2.6 systems. The original commit log follows: Use optparse in js2c.py for python compatibility Without this change, V8 won't build on RHEL/CentOS 6 because the distro python is too old to know about the argparse module.

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.
