2018-10-04src: name EmbededderGraph edges and use class names for nodesJoyee Cheung
This patch: - Refactors the `MemoryRetainer` API so that the impementer no longer calls `TrackThis()` that sets the size of node on the top of the stack, which may be hard to understand. Instead now they implements `SelfSize()` to provide their self sizes. Also documents the API in the header. - Refactors `MemoryTracker` so it calls `MemoryInfoName()` and `SelfSize()` of `MemoryRetainer` to retrieve info about them, and separate `node_names` and `edge_names` so the edges can be properly named with reference names and the nodes can be named with class names. (Previously the nodes are named with reference names while the edges are all indexed and appear as array elements). - Adds `SET_MEMORY_INFO_NAME()`, `SET_SELF_SIZE()` and `SET_NO_MEMORY_INFO()` convenience macros - Fixes a few `MemoryInfo` calls in some `MemoryRetainers` to track their references properly. - Refactors the heapdump tests to check both node names and edge names, distinguishing between wrapped JS nodes (without prefixes) and embedder wrappers (prefixed with `Node / `).

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.

2016-05-24src: no abort from getter if object isn't wrappedTrevor Norris
v8::Object::GetAlignedPointerFromInternalField() returns a random value if Wrap() hasn't been run on the object handle. Causing v8 to abort if certain getters are accessed. It's possible to access these getters and functions during class construction through the AsyncWrap init() callback, and also possible in a subset of those scenarios while running the persistent handle visitor. Mitigate this issue by manually setting the internal aligned pointer field to nullptr in the BaseObject constructor and add necessary logic to return appropriate values when nullptr is encountered.

AsyncListener is a JS API that works in tandem with the AsyncWrap class to allow the user to be alerted to key events in the life cycle of an asynchronous event. The AsyncWrap class has its own MakeCallback implementation that core will be migrated to use, and uses state sharing techniques to allow quicker communication between JS and C++ whether the async event callbacks need to be called.
