Ben Noordhuis	204228b57f	test: move slow tests to test/pummel/ Slowness being somewhat subjective but determined by running the test suite a few times and picking off everything that consistently clocks in at 2 seconds or more. Honorable mention for simple/test-tls-server-large-request, it often runs for 10 (!) seconds or more.	11 years ago

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.

Miroslav Bajtos	c16963b977	src: break on uncaught exception Most TryCatch blocks have SetVerbose flag on, this tells V8 to report uncaught exceptions to debugger. FatalException handler is called from V8 Message listener instead from the place where TryCatch was used. Otherwise uncaught exceptions are logged twice. See comment in `deps/v8/include/v8.h` for explanation of SetVerbose flag: > By default, exceptions that are caught by an external exception > handler are not reported. Call SetVerbose with true on an > external exception handler to have exceptions caught by the > handler reported as if they were not caught. The flag is used by `Isolate::ShouldReportException()`, which is called by `Isolate::DoThrow()` to decide whether an exception is considered uncaught.	12 years ago
