for snapshotted modules (#18041)
This commit renames "deno_core::InternalModuleLoader" to
"ExtModuleLoader" and changes the specifiers used by the
modules loaded from this loader to "ext:".
"internal:" scheme was really ambiguous and it's more characters than
"ext:", which should result in slightly smaller snapshot size.
Closes https://github.com/denoland/deno/issues/18020

Closes #14406

This PR refactors all internal js files (except core) to be written as
ES modules.
`__bootstrap`has been mostly replaced with static imports in form in
`internal:[path to file from repo root]`.
To specify if files are ESM, an `esm` method has been added to
`Extension`, similar to the `js` method.
A new ModuleLoader called `InternalModuleLoader` has been added to
enable the loading of internal specifiers, which is used in all
situations except when a snapshot is only loaded, and not a new one is
created from it.

Updated third_party dlint to v0.37.0 for GitHub Actions. This PR
includes following changes:
* fix(prefer-primordials): Stop using array pattern assignments
* fix(prefer-primordials): Stop using global intrinsics except for
`SharedArrayBuffer`
* feat(guard-for-in): Apply new guard-for-in rule

Yearly tradition of creating extra noise in git.

This commit adds "Deno.Conn.ref()" and "Deno.Conn.unref()" methods.
These methods can be used to make connection block or not block the
event loop from finishing. Refing/unrefing only influences "read"
operations - ie. scheduling writes to a connection _do_ keep event
loop alive.
Required for https://github.com/denoland/deno/issues/16710

(#17003)
This commit stabilizes following APIs:
- `Deno.TcpConn.setNoDelay()`
- `Deno.TcpConn.setKeepAlive()`
|
|
This PR adds copies of several unstable APIs that are available
in "Deno[Deno.internal].nodeUnstable" namespace.
These copies do not perform unstable check (ie. don't require
"--unstable" flag to be present). Otherwise they work exactly
the same, including permission checks.
These APIs are not meant to be used by users directly and
can change at any time.
Copies of following APIs are available in that namespace:
- Deno.spawnChild
- Deno.spawn
- Deno.spawnSync
- Deno.serve
- Deno.upgradeHttpRaw
- Deno.listenDatagram

Should fix https://github.com/denoland/deno_std/issues/2807
|
|
Previously `op_net_listen`, `op_net_accept`, and various other ops in
ext/net where variadic on the transport. This created a lot of code
bloat. This commit updates the code to instead have separate ops for
each transport.
|
|
This commit adds a new op_write_all to core that allows writing an
entire chunk in a single async op call. Internally this calls
`Resource::write_all`.
The `writableStreamForRid` has been moved to `06_streams.js` now, and
uses this new op. Various other code paths now also use this new op.
Closes #16227

Welcome to better optimised op calls! Currently opSync is called with parameters of every type and count. This most definitely makes the call megamorphic. Additionally, it seems that spread params leads to V8 not being able to optimise the calls quite as well (apparently Fast Calls cannot be used with spread params).
Monomorphising op calls should lead to some improved performance. Now that unwrapping of sync ops results is done on Rust side, this is pretty simple:
```
opSync("op_foo", param1, param2);
// -> turns to
ops.op_foo(param1, param2);
```
This means sync op calls are now just directly calling the native binding function. When V8 Fast API Calls are enabled, this will enable those to be called on the optimised path.
Monomorphising async ops likely requires using callbacks and is left as an exercise to the reader.

This commit adds `readable` and `writable` properties to `Deno.File` and
`Deno.Conn`. This makes it very simple to use files and network sockets
with fetch or the native HTTP server.

This allows resources to be "streams" by implementing read/write/shutdown. These streams are implicit since their nature (read/write/duplex) isn't known until called, but we could easily add another method to explicitly tag resources as streams.
`op_read/op_write/op_shutdown` are now builtin ops provided by `deno_core`
Note: this current implementation is simple & straightforward but it results in an additional alloc per read/write call
Closes #12556

Currently all async ops are polled lazily, which means that op
initialization code is postponed until control is yielded to the event
loop. This has some weird consequences, e.g.
```js
let listener = Deno.listen(...);
let conn_promise = listener.accept();
listener.close();
// `BadResource` is thrown. A reasonable error would be `Interrupted`.
let conn = await conn_promise;
```
JavaScript promises are expected to be eagerly evaluated. This patch
makes ops actually do that.
