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.

The pointer used to hold an incoming dynamically loaded module's `node::node_module` structure needs to be thread-local. So far this was done with `uv_key_set()` and `uv_key_get()`. The language now supports the `thread_local` keyword which makes implementing this a lot cleaner.

2019-01-18src: merge into coreGireesh Punathil
Make node-report part of core runtime because: 1. When enabled, node-report significantly helps root cause various types of problems, including support issues sent to the various repos of the Node.js organization. 2. The requirement of explicitly adding the dependency to node-report in user applications often represents a blocker to adoption. Major deviation from the module version of the node-report is that the report is generated in JSON format, as opposed to human readable text. No new functionalities have been added, changes that are required for melding it as a built-in capability has been affected on the module version of node-report (https://github.com/nodejs/node-report) Co-authored-by: Bidisha Pyne <bidipyne@in.ibm.com> Co-authored-by: Howard Hellyer <hhellyer@uk.ibm.com> Co-authored-by: Jeremiah Senkpiel <fishrock123@rocketmail.com> Co-authored-by: Julian Alimin <dmastag@yahoo.com> Co-authored-by: Lakshmi Swetha Gopireddy <lakshmigopireddy@in.ibm.com> Co-authored-by: Manusaporn Treerungroj <m.treerungroj@gmail.com> Co-authored-by: Michael Dawson <michael_dawson@ca.ibm.com> Co-authored-by: Richard Chamberlain <richard_chamberlain@uk.ibm.com> Co-authored-by: Richard Lau <riclau@uk.ibm.com> Co-authored-by: Sam Roberts <vieuxtech@gmail.com> Co-authored-by: Vipin Menon <vipinmv1@in.ibm.com> PR-URL: https://github.com/nodejs/node/pull/22712 Reviewed-By: Anna Henningsen <anna@addaleax.net> Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Michael Dawson <Michael_Dawson@ca.ibm.com> Reviewed-By: Vse Mozhet Byt <vsemozhetbyt@gmail.com>

2018-12-21src: move more process methods initialization in bootstrap/node.jsJoyee Cheung
Instead of: - Writing methods onto the process directly in C++ during `SetupProcessObject()` and overwrite with argument checks later - Or, wrapping and writing them in `internal/process/*.js` Do: - Move the C++ implementations in node_process.cc and mark them static wherever possible - Expose the C++ methods through a new `internalBinding('process_methods')` - Wrap the methods in `internal/process/*.js` in a side-effect-free manner and return them back to `internal/bootstrap/node.js` - Centralize the write to the process object based on conditions in `bootstrap/node.js` So it's easier to see what methods are attached to the process object during bootstrap under what condition and in what order. The eventual goal is to figure out the dependency of process methods and the write/read access to the process object during bootstrap, group these access properly and remove the process properties that should not be exposed to users this way. Also correct the NODE_PERFORMANCE_MILESTONE_BOOTSTRAP_COMPLETE milestone which should be marked before code execution.

2018-12-18src: always compile and store code cache for native modulesJoyee Cheung
This patch changes the NativeModuleLoader to always try to find code cache for native modules when it compiles them, and always produce and store the code cache after compilation. The cache map is protected by a mutex and can be accessed by different threads - including the worker threads and the main thread. Hence any thread can reuse the code cache if the native module has already been compiled by another thread - in particular the cache of the bootstrappers and per_context.js will always be hit when a new thread is spun. This results in a ~6% startup overhead in the worst case (when only the main thread is launched without requiring any additional native module - it now needs to do the extra work of finding and storing caches), which balances out the recent improvements by moving the compilation to C++, but it also leads to a ~60% improvement in the best case (when a worker thread is spun and requires a lot of native modules thus hitting the cache compiled by the main thread).

2018-12-11process: specialize building and storage of process.configJoyee Cheung
Instead of treating config.gypi as a JavaScript file, specialize the processing in js2c and make the serialized result a real JSON string (with 'true' and 'false' converted to boolean values) so we don't have to use a custom deserializer during bootstrap. In addition, store the JSON string separately in NativeModuleLoader, and keep it separate from the map of the builtin source code, so we don't have to put it onto `NativeModule._source` and delete it later, though we still preserve it in `process.binding('natives')`, which we don't use anymore. This patch also makes the map of builtin source code and the config.gypi string available through side-effect-free getters in C++.
