2019-04-12src: replace FromJust() with Check() when possibleSam Roberts
FromJust() is often used not for its return value, but for its side-effects. In these cases, Check() exists, and is more clear as to the intent. From its comment: To be used, where the actual value of the Maybe is not needed, like Object::Set.

2019-03-05src: use object to pass `Environment` to functionsAnna Henningsen
Use a `v8::Object` with an internal field, rather than a `v8::External`. On a `GetReturnValue().Set(Environment::GetCurrent(args) == nullptr)` noop function, this benchmarks as a ~60 % speedup, as calls to `obj->GetAlignedPointerFromInternalField()` can be inlined and the field is stored with one level of indirection less. This also makes breaking up some pieces of the `Environment` class into per-native-binding data easier, if we want to pursue that path in the future.

Encapsulate stream requests more: - `WriteWrap` and `ShutdownWrap` classes are now tailored to the streams on which they are used. In particular, for most streams these are now plain `AsyncWrap`s and do not carry the overhead of unused libuv request data. - Provide generic `Write()` and `Shutdown()` methods that wrap around the actual implementations, and make *usage* of streams easier, rather than implementing; for example, wrap objects don’t need to be provided by callers anymore. - Use `EmitAfterWrite()` and `EmitAfterShutdown()` handlers to call the corresponding JS handlers, rather than always trying to call them. This makes usage of streams by other C++ code easier and leaner. Also fix up some tests that were previously not actually testing asynchronicity when the comments indicated that they would.

2017-12-13src: minor refactoring to StreamBase writesAnna Henningsen
Instead of having per-request callbacks, always call a callback on the `StreamBase` instance itself for `WriteWrap` and `ShutdownWrap`. This makes `WriteWrap` cleanup consistent for all stream classes, since the after-write callback is always the same now. If special handling is needed for writes that happen to a sub-class, `AfterWrite` can be overridden by that class, rather than that class providing its own callback (e.g. updating the write queue size for libuv streams). If special handling is needed for writes that happen on another stream instance, the existing `after_write_cb()` callback is used for that (e.g. custom code after writing to the transport from a TLS stream). As a nice bonus, this also makes `WriteWrap` and `ShutdownWrap` instances slightly smaller.

2017-05-10src: implement native changes for async_hooksTrevor Norris
Changes in the native code for the upcoming async_hooks module. These have been separated to help with review and testing. Changes include: * Introduce an async id stack that tracks recursive calls into async execution contexts. For performance reasons the id stack is held as a double* and assigned to a Float64Array. If the stack grows too large it is then placed in it's own stack and replaced with a new double*. This should accommodate arbitrarily large stacks. I'm not especially happy with the complexity involved with this async id stack, but it's also the fastest and most full proof way of handling it that I have found. * Add helper functions in Environment and AsyncWrap to work with the async id stack. * Add AsyncWrap::Reset() to allow AsyncWrap instances that have been placed in a resource pool, instead of being released, to be reinitialized. AsyncWrap::AsyncWrap() also now uses Reset() for initialization. * AsyncWrap* parent no longer needs to be passed via the constructor. * Introduce Environment::AsyncHooks class to contain the needed native functionality. This includes the pointer to the async id stack, and array of v8::Eternal<v8::String>'s that hold the names of all providers, mechanisms for storing/retrieving the trigger id, etc. * Introduce Environment::AsyncHooks::ExecScope as a way to track the current id and trigger id of function execution via RAII. * If the user passes --abort-on-uncaught-exception then instead of throwing the application will print a stack trace and abort.

2017-05-10async_wrap,src: add GetAsyncId() methodTrevor Norris
Allow handles to retrieve their own uid's by adding a new method on the FunctionTemplates. Implementation of these into all other classes will come in a future commit. Add the method AsyncWrap::GetAsyncId() to all inheriting class objects so the uid of the handle can be retrieved from JS. In all applicable locations, run ClearWrap() on the object holding the pointer so that it never points to invalid memory and make sure Wrap() is always run so the class pointer is correctly attached to the object and can be retrieved so GetAsyncId() can be run. In many places a class instance was not removing its own pointer from object() in the destructor. This left an invalid pointer in the JS object that could cause the application to segfault under certain conditions. Remove ClearWrap() from ReqWrap for continuity. The ReqWrap constructor was not the one to call Wrap(), so it shouldn't be the one to call ClearWrap(). Wrap() has been added to all constructors that inherit from AsyncWrap. Normally it's the child most class. Except in the case of HandleWrap. Which must be the constructor that runs Wrap() because the class pointer is retrieved for certain calls and because other child classes have multiple inheritance to pointer to the HandleWrap needs to be stored. ClearWrap() has been placed in all FunctionTemplate constructors so that no random values are returned when running getAsyncId(). ClearWrap() has also been placed in all class destructors, except in those that use MakeWeak() because the destructor will run during GC. Making the object() inaccessible. It could be simplified to where AsyncWrap sets the internal pointer, then if an inheriting class needs one of it's own it could set it again. But the inverse would need to be true also, where AsyncWrap then also runs ClearWeak. Unforunately because some of the handles are cleaned up during GC that's impossible. Also in the case of ReqWrap it runs Reset() in the destructor, making the object() inaccessible. Meaning, ClearWrap() must be run by the class that runs Wrap(). There's currently no generalized way of taking care of this across all instances of AsyncWrap. I'd prefer that there be checks in there for these things, but haven't found a way to place them that wouldn't be just as unreliable. Add test that checks all resources that can run getAsyncId(). Would like a way to enforce that any new classes that can also run getAsyncId() are tested, but don't have one.
