This step converts as many explicit accesses as possible in favor of direct imports from the modules in which things were declared. This restores the code (as much as possible) back to how it looked originally before the explicitify step, e.g. instead of "ts.Node" and "ts.Symbol", we have just "Node" and "Symbol".
This step converts each file into an exported module by hoisting the namespace bodies into the global scope and transferring internal markers down onto declarations as needed.
The namespaces are reconstructed as "barrel"-style modules, which are identical to the old namespace objects in structure. These reconstructed namespaces are then imported in the newly module-ified files, making existing expressions like "ts." valid.
* fix(51100): ensure tsserver shuts down when parent process is killed
When using IPC channel (`--useNodeIpc`) for communicating with tsserver,
the child tsserver process did not shut down on parent process disconnecting
(for example due to it being killed).
Call exit() on IPC disconnect, same as stdio-based communication did
when pipe to parent process was destroyed.
* don't duplicate inherited method

* Use fs events as default watching
* Some refactoring
* Make single per directory native watchers now that we are using it as default
* Rename
* Comment

* Prototype TS plugins on web
This prototype allows service plugins to be loaded on web TSServer
Main changes:
- Adds a new host entryPoint called `importServicePlugin` for overriding how plugins can be loaded. This may be async
- Implement `importServicePlugin` for webServer
- The web server plugin implementation looks for a `browser` field in the plugin's `package.json`
- It then uses `import(...)` to load the plugin (the plugin source must be compiled to support being loaded as a module)
* use default export from plugins
This more or less matches how node plugins expect the plugin module to be an init function
* Allow configure plugin requests against any web servers in partial semantic mode
* Addressing some comments
- Use result value instead of try/catch (`ImportPluginResult`)
- Add awaits
- Add logging
* add tsserverWeb to patch in dynamic import
* Remove eval
We should throw instead when dynamic import is not implemented
* Ensure dynamically imported plugins are loaded in the correct order
* Add tests for async service plugin timing
* Update src/server/editorServices.ts

* Merge 'decorators' into 'modifiers' on various Nodes
* Drop RESERVED argument in favor of removing parameter
* Ignore grammar error nodes when asserting invariants
* Revert 'illegalX' property renames
* PR Feedback
* Use node ipc for TS Server
For #46417
This lets us use Node's built-in ipc for passing messages to/from the typescript server instead of using stdio
* Remove extra parse
* Add extra logging when using node IPC
* Split out to subclass
* Extract common writeMessage method
* Baseline accept
* shorthand -> long for `factory` since the typeformer script doesn't
know how to handle it.
* Use setter to change `ts.sys` (similar to #35399).
* Fix `loggedIO` with empty namespaces to indicate dependency
(similar to 50603eda).
* Move `Map` / `Set` stuff from `core.ts` to `corePublic.ts` since the
types are there.
Make `tracing` either `undefined` or the same namespace as before.
Switching all calls to `tracing?.___` means that there is no cost for
a call or the arguments when tracing is not used. Comparing two runs
without tracing (27 runs, drop 5+5, avg rest) I get:
master:
42.59s user 1.00s system 165% cpu 26.372 total
changed:
42.01s user 0.982 system 165% cpu 26.039 total
(Makes it all private, so no api changes.)
* Adds experimental support for running TS Server in a web worker
This change makes it possible to run a syntax old TS server in a webworker. This is will let serverless versions of VS Code web run the TypeScript extension with minimal changes.
As the diff on `server.ts` is difficult to parse, here's an overview of the changes:
- Introduce the concept of a `Runtime`. Valid values are `Node` and `Web`.
- Move calls to `require` into the functions that use these modules
- Wrap existing server logic into `startNodeServer`
- Introduce web server with `startWebServer`. This uses a `WorkerSession`
- Add a custom version of `ts.sys` for web
- Have the worker server start when it is passed an array of arguments in a message
In order to make the server logic more clear, this change also tries to reduce the reliance on closures and better group function declarations vs the server spawning logic.
**Next Steps**
I'd like someone from the TS team to help get these changes into a shippable state. This will involve:
- Adddress todo comments
- Code cleanup
- Make sure these changes do not regress node servers
- Determine if we should add a new `tsserver.web.js` file instead of having the web worker logic all live in `tsserver.js`
* Shim out directoryExists
* Add some regions
* Remove some inlined note types
Use import types instead
* Use switch case for runtime
* Review and updates
* Enable loading std library d.ts files
This implements enough of `ServerHost` that we can load the standard d.ts files using synchronous XMLHttpRequests.
I also had to patch some code in `editorServices`. I don't know if these changes are correct and need someone on the TS team to review
* Update src/tsserver/webServer.ts
* Update src/tsserver/webServer.ts

* Addressing feedback
* Allow passing in explicit executingFilePath
This is required for cases where `self.location` does not point to the directory where all the typings are stored
* Adding logging support
* Do not create auto import provider in partial semantic mode
* Handle lib files by doing path mapping instead
* TODO
* Add log message
This replaces the console based logger with a logger that post log messages back to the host. VS Code will write these messages to its output window
* Move code around so that exported functions are set on namespace
* Log response
* Map the paths back to https:
// TODO: is this really needed or can vscode take care of this
How do we handle when opening lib.d.ts as response to goto def in open files
* If files are not open dont schedule open file project ensure
* Should also check if there are no external projects before skipping scheduling
Fixes failing tests
* Revert "Map the paths back to https:"
This reverts commit 0edf650622.
* Revert "TODO"
This reverts commit 04a4fe7556.
* Revert "Should also check if there are no external projects before skipping scheduling"
This reverts commit 7e4939014a.
* Refactoring so we can test the changes out

Future versions of node will be able to return undefined, rather than
allocating and throwing an exception, when a file is not found.
See https://github.com/nodejs/node/pull/33716
* Add tracing support to tsserver
Read the `TSS_TRACE` environment variable to determine which directory
trace files should be written to.

3) New, server-specific events (request/response, cancellation, etc)

* Rename stepCancellation to stepCanceledEarly
* Rename stepEarlyCancellation to stepCanceled and use flag instead
* Check correct variable on exit
* fix: IOSession access this before calling super
close#40399
This makes the TS server crashes if the build target is ES6 or higher.
