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>
2019-10-31src: change env.h includes for forward declarationsAlexandre Ferrando
Due to how the Environment class is used through the codebase, there are a lot of includes referencing either env.h or env-inl.h. This can cause that when any development touches those libraries, a lot of files have to be recompiled. This commit attempts to change those includes by forward declarations when possible to mitigate the issue.

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.

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.

Causing a segfault when a heapdump was taken. This has been added, and the label_ set to the given provider name so each instance can be identified. The id will not be set of the passed object has no internal field count. As the class pointer cannot be retrieved from the object.

2015-02-22stream_base: introduce StreamBaseFedor Indutny
StreamBase is an improved way to write C++ streams. The class itself is for separting `StreamWrap` (with the methods like `.writeAsciiString`, `.writeBuffer`, `.writev`, etc) from the `HandleWrap` class, making possible to write abstract C++ streams that are not bound to any uv socket. The following methods are important part of the abstraction (which mimics libuv's stream API): * Events: * `OnAlloc(size_t size, uv_buf_t*)` * `OnRead(ssize_t nread, const uv_buf_t*, uv_handle_type pending)` * `OnAfterWrite(WriteWrap*)` * Wrappers: * `DoShutdown(ShutdownWrap*)` * `DoTryWrite(uv_buf_t** bufs, size_t* count)` * `DoWrite(WriteWrap*, uv_buf_t*, size_t count, uv_stream_t* handle)` * `Error()` * `ClearError()` The implementation should provide all of these methods, thus providing the access to the underlying resource (be it uv handle, TLS socket, or anything else). A C++ stream may consume the input of another stream by replacing the event callbacks and proxying the writes. This kind of API is actually used now for the TLSWrap implementation, making it possible to wrap TLS stream into another TLS stream. Thus legacy API calls are no longer required in `_tls_wrap.js`.
