To fix bugs around detection of when node emulation is required, we will
just eagerly initialize it. The improvements we make to reduce the
impact of the startup time:
- [x] Process stdin/stdout/stderr are lazily created
- [x] node.js global proxy no longer allocates on each access check
- [x] Process checks for `beforeExit` listeners before doing expensive
shutdown work
- [x] Process should avoid adding global event handlers until listeners
are added

The goal of this PR is to address issue #19520 where Deno panics when
encountering an invalid SSL certificate.
This PR achieves that goal by removing an `.expect()` statement and
implementing a match statement on `tsl_config` (found in
[/ext/net/ops_tsl.rs](e071382768/ext/net/ops_tls.rs (L1058)))
to check whether the desired configuration is valid

Fix #20022, fix #19627 (duplicate)
#17333 upgraded clap from version 3.1 to version 4. clap version 3.2.0
(intentionally) broke a behavior that deno was relying on to make `deno
run --v8-flags=--help` work without specifying a file, see
clap-rs/clap#3793. The workaround was to make the script argument
required _unless_ `--v8-flags` is present. This broke the expectation
that all successfully parsed `run` commands have the script argument
set, leading to the panic on
`matches.remove_many::<String>("script_arg").unwrap()`.
Clap, as far as I was able to find out, does not currently offer a neat
solution to this problem. This PR adds logic to create and return a
custom clap error when a parsed run command does not have the script
argument.
I added an appropriate test.
Handles ASCCI espace chars in test and bench name making
test and bench reporting more reliable. This one is also tested
in the fixture of "node:test" module.
The original implementation of `Cache` used a custom `shutdown` method
on the resource, but to simplify fast streams work we're going to move
this to an op of its own.
While we're in here, we're going to replace `opAsync` with
`ensureFastOps`. `op2` work will have to wait because of some
limitations to our async support, however.
Rename some of the helper methods on the Fs trait to be suffixed with
`_sync` / `_async`, in preparation of the introduction of more async
methods for some helpers.
Also adds a `read_text_file_async` helper to complement the renamed
`read_text_file_sync` helper.
This commit moves `snapshot_from_lockfile` function to [deno_npm
crate](https://github.com/denoland/deno_npm). This allows this function
to be called outside Deno CLI (in particular, Deno Deploy).
This PR ensures that the original signal event is fired before any
dependent signal events.

The enabled tests fail on `main`:
```
assert_array_equals: Abort events fired in correct order expected property 0 to be
"original-aborted" but got "clone-aborted" (expected array ["original-aborted", "clone-aborted"]
got ["clone-aborted", "original-aborted"])
```
Not sure why `40_testing.js` is there. The other two `00_typescript.js`
and `99_main_compiler.js` should be covered by
`files_loaded_during_snapshot` at the end.
This helps with `__runtime_js_sources` wrt changing `40_testing.js`.
Renames the unstable `deno_modules` directory and corresponding settings
to `vendor` after feedback. Also causes the vendoring of the
`node_modules` directory which can be disabled via
`--node-modules-dir=false` or `"nodeModulesDir": false`.
This changes the design of the manifest.json file to have a separate
"folders" map for mapping hashed directories. This allows, for example,
to add files in a folder like `http_localhost_8000/#testing_5de71/` and
have them be resolved automatically as long as their remaining
components are identity-mappable to the file system (not hashed). It
also saves space in the manifest.json file by only including the hashed
directory instead of each descendant file.
```
// manifest.json
{
"folders": {
"https://localhost/NOT_MAPPABLE/": "localhost/#not_mappable_5cefgh"
},
"modules": {
"https://localhost/folder/file": {
"headers": {
"content-type": "application/javascript"
}
},
}
}
// folder structure
localhost
- folder
- #file_2defn (note: I've made up the hashes in these examples)
- #not_mappable_5cefgh
- mod.ts
- etc.ts
- more_files.ts
```
Closes #19399 (running without snapshots at all was suggested as an
alternative solution).
Adds a `__runtime_js_sources` pseudo-private feature to load extension
JS sources at runtime for faster development, instead of building and
loading snapshots or embedding sources in the binary. Will only work in
a development environment obviously.
Try running `cargo test --features __runtime_js_sources
integration::node_unit_tests::os_test`. Then break some behaviour in
`ext/node/polyfills/os.ts` e.g. make `function cpus() {}` return an
empty array, and run it again. Fix and then run again. No more build
time in between.

This PR removes that warning and improves coverage.
This bumps `async-compression` dependency in `deno_http` to latest, in
order to avoid having multiple duplicate versions.
Related, it also unpin a stale `flate2` dependency so that the whole
chain of `async-compression` -> `flate2` -> `miniz_oxide` can surface up
to current versions.
The lockfile entries for all of the above crates have been update
accordingly; the new tree of dependencies looks like this:
```
$ cargo tree -i -p miniz_oxide
miniz_oxide v0.7.1
└── flate2 v1.0.26
└── async-compression v0.4.1
```
This tweaks the HTTP response-writer in order to align the two possible
execution flows into using the same gzip default compression level, that
is `1` (otherwise the implicit default level is `6`).
This PR fixes some crashing WPT tests due to an unresolved promise.

This could be a [stream spec](https://streams.spec.whatwg.org) bug
When `controller.close` is called on a byob stream, there's no cleanup
of pending `readIntoRequests`. The only cleanup of pending
`readIntoRequests` happen when `.byobRequest.respond(0)` is called, it
happens
here:6ba245fe25/ext/web/06_streams.js (L2026)
which ends up calling `readIntoRequest.closeSteps(chunk);` in
6ba245fe25/ext/web/06_streams.js (L2070)
To reproduce:
```js
async function byobRead() {
const input = [new Uint8Array([8, 241, 48, 123, 151])];
const stream = new ReadableStream({
type: "bytes",
async pull(controller) {
if(input.length === 0) {
controller.close();
// controller.byobRequest.respond(0); // uncomment for fix
return
}
controller.enqueue(input.shift())
},
});
const reader = stream.getReader({ mode: 'byob' });
const r1 = await reader.read(new Uint8Array(64));
console.log(r1);
const r2 = await reader.read(new Uint8Array(64));
console.log(r2);
}
await byobRead();
```
Running the script triggers:
```
error: Top-level await promise never resolved
```
