Currently we evict a lot of the caches on the JS side of things on every
request, namely script versions, script file names, and compiler
settings (as of #23283, it's not quite every request but it's still
unnecessarily often).
This PR reports changes to the JS side, so that it can evict exactly the
caches that it needs too. We might want to do some batching in the
future so as not to do 1 request per change.
This commit adds a way to connect to the TS compiler host that is run
as part of the "deno lsp" subcommand. This can be done by specifying
"DENO_LSP_INSPECTOR" variable.

Adds performance measurements for all ops used by the LSP. Also changes
output of "Language server status" page to include more precise
information.
Current suspicion is that computing "script version" takes a long time
for some users.
Adds an `--unstable-sloppy-imports` flag which supports the
following for `file:` specifiers:
* Allows writing `./mod` in a specifier to do extension probing.
- ex. `import { Example } from "./example"` instead of `import { Example
} from "./example.ts"`
* Allows writing `./routes` to do directory extension probing for files
like `./routes/index.ts`
* Allows writing `./mod.js` for *mod.ts* files.
This functionality is **NOT RECOMMENDED** for general use with Deno:
1. It's not as optimal for perf:
https://marvinh.dev/blog/speeding-up-javascript-ecosystem-part-2/
1. It makes tooling in the ecosystem more complex in order to have to
understand this.
1. The "Deno way" is to be explicit about what you're doing. It's better
in the long run.
1. It doesn't work if published to the Deno registry because doing stuff
like extension probing with remote specifiers would be incredibly slow.
This is instead only recommended to help with migrating existing
projects to Deno. For example, it's very useful for getting CJS projects
written with import/export declaration working in Deno without modifying
module specifiers and for supporting TS ESM projects written with
`./mod.js` specifiers.
This feature will output warnings to guide the user towards correcting
their specifiers. Additionally, quick fixes are provided in the LSP to
update these specifiers:
This commit changes LSP log names by prefixing them, we now have these
prefixes:
- `lsp.*` - requests coming from the client
- `tsc.request.*` - requests coming from clients that are routed to TSC
- `tsc.op.*` - ops called by the TS host
- `tsc.host.*` - requests that call JavaScript runtime that runs
TypeScript compiler host
Additionall `Performance::mark` was split into `Performance::mark` and
`Performance::mark_with_args` to reduce verbosity of code and logs.
When an old request is obsoleted while the user is typing, the client
will say so to the server and tower-lsp will drop the future associated
with that request.
This wires that up to the ts server by having any request's token be
cancelled when the surrounding state is dropped.
This makes `CliNpmResolver` a trait. The terminology used is:
- **managed** - Deno manages the node_modules folder and does an
auto-install (ex. `ManagedCliNpmResolver`)
- **byonm** - "Bring your own node_modules" (ex. `ByonmCliNpmResolver`,
which is in this PR, but unimplemented at the moment)
Part of #18967
When sending configuration requests to the client, reads `javascript`
and `typescript` sections in addition to `deno`.
The LSP's initialization options now accepts `javascript` and
`typescript` namespaces.
Give auto-import completion entries a sort-text suffix depending on if
the specifier parses as a URL. This will favour relative and bare
(likely import-mapped) specifiers.
Removes usage of `serde_json::Value` in several ops used in TSC, in
favor of using strongly typed structs. This will unblock more
changes in https://github.com/denoland/deno/pull/20462.
