2019-11-28src: cleanup unused headersAlexandre Ferrando
Node codebase has evolved a lot in the more than 10 years of its existence. As more features (and code) have been added, changed, removed, it's sometimes hard to keep track of what gets used and what not. This commits attempts to clean some of those potentially left-over headers using suggestions from include-what-you-use Refs: https://github.com/nodejs/node/issues/27531 PR-URL: https://github.com/nodejs/node/pull/30328 Reviewed-By: Anna Henningsen <anna@addaleax.net> Reviewed-By: Joyee Cheung <joyeec9h3@gmail.com> Reviewed-By: James M Snell <jasnell@gmail.com>
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 / `).

2018-07-27src: add proper MemoryInfoName to wrappersJoyee Cheung
- Use camel case names for memory retainers inherited from AsyncWrap instead of their provider names (which are all in upper case) - Assign class names to wraps so that they appear in the heap snapshot as nodes with class names as node names. Previously some nodes are named with reference names, which are supposed to be edge names instead.

2018-05-04src: refactor `BaseObject` internal field managementAnna Henningsen
- Instead of storing a pointer whose type refers to the specific subclass of `BaseObject`, just store a `BaseObject*` directly. This means in particular that one can cast to classes along the way of the inheritance chain without issues, and that `BaseObject*` no longer needs to be the first superclass in the case of multiple inheritance. In particular, this renders hack-y solutions to this problem (like ddc19be6de1ba263d9c175b2760696e7b9918b25) obsolete and addresses a `TODO` comment of mine. - Move wrapping/unwrapping methods to the `BaseObject` class. We use these almost exclusively for `BaseObject`s, and I hope that this gives a better idea of how (and for what) these are used in our code. - Perform initialization/deinitialization of the internal field in the `BaseObject*` constructor/destructor. This makes the code a bit more obviously correct, avoids explicit calls for this in subclass constructors, and in particular allows us to avoid crash situations when we previously called `ClearWrap()` during GC. This also means that we enforce that the object passed to the `BaseObject` constructor needs to have an internal field. This is the only reason for the test change. - Change the signature of `MakeWeak()` to not require a pointer argument. Previously, this would always have been the same as `this`, and no other value made sense. Also, the parameter was something that I personally found somewhat confusing when becoming familiar with Node’s code. - Add a `TODO` comment that motivates switching to real inheritance for the JS types we expose from the native side. This patch brings us a lot closer to being able to do that. - Some less significant drive-by cleanup. Since we *effectively* already store the `BaseObject*` pointer anyway since ddc19be6de1ba263d9c175b2760696e7b9918b25, I do not think that this is going to have any impact on diagnostic tooling.

2018-04-18src: remove req_wrap-inl.h from stream_base.hDaniel Bevenius
This commit removes the inclusion of req_wrap-inl.h in stream_base.h as ReqWrap is not used. This removal required stream_base.h to include async_wrap-inl.h so there is an implementation of BaseObject::object. The above change also affected connect_wrap, which needs to include req_wrap-inl.h to get an implementation of ReqWrap::Dispatched.

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.
