2021-07-15fs: fix FileHandle::ClosePromise to return persisted PromiseJames M Snell
Makes the FileHandle::ClosePromise() idempotent, always returning the same Promise after it has already been successfully called once. Avoids the possibility of accidental double close events.

2021-02-08src: rename binding_data_name to type_name in BindingDataJoyee Cheung
Previously, this was a per-class string constant for BindingData which is used as keys for identifying these objects in the binding data map. These are just type names of the BindingData. This patch renames the variable to type_name so that we can generalize this constant for other BaseObjects and use it for debugging and logging the types of other BaseObjects.

2020-05-15fs: clean up Dir.read() uv_fs_t data before calling into JSAnna Henningsen
A call into JS can schedule another operation on the same `uv_dir_t`. In particular, when the handle is closed from the callback for a directory read operation, there previously was a race condition window: 1. A `dir.read()` operation is submitted to libuv 2. The read operation is finished by libuv, calling `AfterDirRead()` 3. We call into JS 4. JS calls dir.close() 5. libuv posts the close request to a thread in the pool 6. The close request runs, destroying the directory handle 7. `AfterDirRead()` is being exited. Exiting the `FSReqAfterScope` in step 7 attempts to destroy the original uv_fs_t` from step 1, which now points to an `uv_dir_t` that has already been destroyed in step 5. By forcing the `FSReqAfterScope` to clean up before we call into JS, we can be sure that no other operations on the same `uv_dir_t` are submitted concurrently. This addresses issues observed when running with ASAN/valgrind. PR-URL: https://github.com/nodejs/node/pull/33274 Reviewed-By: Colin Ihrig <cjihrig@gmail.com>

2019-10-08fs: introduce `opendir()` and `fs.Dir`Jeremiah Senkpiel
This adds long-requested methods for asynchronously interacting and iterating through directory entries by using `uv_fs_opendir`, `uv_fs_readdir`, and `uv_fs_closedir`. `fs.opendir()` and friends return an `fs.Dir`, which contains methods for doing reads and cleanup. `fs.Dir` also has the async iterator symbol exposed. The `read()` method and friends only return `fs.Dirent`s for this API. Having a entry type or doing a `stat` call is deemed to be necessary in the majority of cases, so just returning dirents seems like the logical choice for a new api. Reading when there are no more entries returns `null` instead of a dirent. However the async iterator hides that (and does automatic cleanup). The code lives in separate files from the rest of fs, this is done partially to prevent over-pollution of those (already very large) files, but also in the case of js allows loading into `fsPromises`. Due to async_hooks, this introduces a new handle type of `DIRHANDLE`. This PR does not attempt to make complete optimization of this feature. Notable future improvements include: - Moving promise work into C++ land like FileHandle. - Possibly adding `readv()` to do multi-entry directory reads. - Aliasing `fs.readdir` to `fs.scandir` and doing a deprecation.

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 / `).

2018-05-04src: 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.

2017-12-18fs: refactor FSReqWrap and AfterJames M Snell
Separate FSReqWrap definition into a new node_file.h. Add Reject and Resolve methods to encapsulate the callbacks and make the constructor, destructor protected instead of private in preparation to make FSReqWrap subclassable for the Promises implementation. Rework and simplify the After function slightly in preparation for a refactor. Introduce the node::fs namespace instead of using an anonymous namespace for fs methods.
