This commit introduces deprecation warnings for "Deno.*" APIs.
This is gonna be quite noisy, but should tremendously help with user
code updates to ensure
smooth migration to Deno 2.0. The warning is printed at each unique call
site to help quickly
identify where code needs to be adjusted. There's some stack frame
filtering going on to
remove frames that are not useful to the user and would only cause
confusion.
The warning can be silenced using "--quiet" flag or
"DENO_NO_DEPRECATION_WARNINGS" env var.
"Deno.run()" API is now using this warning. Other deprecated APIs will
start warning
in follow up PRs.
Example:
```js
import { runEcho as runEcho2 } from "http://localhost:4545/run/warn_on_deprecated_api/mod.ts";
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
async function runEcho() {
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
}
await runEcho();
await runEcho();
for (let i = 0; i < 10; i++) {
await runEcho();
}
await runEcho2();
```
```

Closes #21839
This commit adds support for [Stage 3 Temporal API
proposal](https://tc39.es/proposal-temporal/docs/).
The API is available when `--unstable-temporal` flag is passed.

import process from "node:process";
process.on("rejectionHandled", (promise) => {
console.log("rejectionHandled", reason, promise);
});
window.addEventListener("rejectionhandled", (event) => {
console.log("rejectionhandled", event.reason, event.promise);

Part 1 of #21713
Changes:
- Remove `.present()` and add a `presentGPUCanvasContext` (not exposed
yet to users)
- Move lazy load logic to `00_init.js`. This can be used to use webgpu
on-demand from future code (OffScreenCanvas)
Harden the code that does permission checks to protect against
re-opening of stdin.
Code that runs FFI is vulnerable to an attack where fd 0 is closed
during a permission check and re-opened with a file that contains a
positive response (ie: `y` or `A`). While FFI code is dangerous in
general, we can make it more difficult for FFI-enabled code to bypass
additional permission checks.
- Checks to see if the underlying file for stdin has changed from the
start to the end of the permission check (detects races)
- Checks to see if the message is excessively long (lowering the window
for races)
- Checks to see if stdin and stderr are still terminals at the end of
the function (making races more difficult)
Main change is that:
- "hyper" has been renamed to "hyper_v014" to signal that it's legacy
- "hyper1" has been renamed to "hyper" and should be the default
`opAsync` requires a lookup by name on each async call. This is a
mechanical translation of all opAsync calls to ensureFastOps.
The `opAsync` API on Deno.core will be removed at a later time.
This PR implements the child_process IPC pipe between parent and child.
The implementation uses Windows named pipes created by parent and passes
the inheritable file handle to the child.
I've also replace parts of the initial implementation which passed the
raw parent fd to JS with resource ids instead. This way no file handle
is exposed to the JS land (both parent and child).
`IpcJsonStreamResource` can stream upto 800MB/s of JSON data on Win 11

Bumped versions for 1.39.0
Please ensure:
- [x] Target branch is correct (`vX.XX` if a patch release, `main` if
minor)
- [x] Crate versions are bumped correctly
- [x] deno_std version is incremented in the code (see
`cli/deno_std.rs`)
- [x] Releases.md is updated correctly (think relevancy and remove
reverts)

This PR implements the Node child_process IPC functionality in Deno on
Unix systems.
For `fd > 2` a duplex unix pipe is set up between the parent and child
processes. Currently implements data passing via the channel in the JSON
serialization format.
This fixes #21434 for `BroadcastChannel` and `WebSocketStream`.
`--unstable` still enable both, but granular unstable flags now also
work:
* `--unstable-net` now enables `WebSocketStream`.
* `--unstable-broadcast-channel` now enables `BroadcastChannel`.
* Additionally, there are now tests for all granular unstable flags.
Since `unsafe-proto` already had tests, so I didn't add any for this
one.
It also introduces a map to keep track of granular unstable ids without
having to sync multiple places.
This commit brings back usage of primordials in "40_testing.js" by
turning it back into an ES module and using new "lazy loading" functionality
of ES modules coming from "deno_core".
The same approach was applied to "40_jupyter.js".

This commit refactors how we access "core", "internals" and
"primordials" objects coming from `deno_core`, in our internal JavaScript code.
Instead of capturing them from "globalThis.__bootstrap" namespace, we
import them from recently added "ext:core/mod.js" file.
Landing changes required for
https://github.com/denoland/deno_core/pull/359
We needed to update 99_main.js and a whole load of tests.
API changes:
- setPromiseRejectCallback becomes setUnhandledPromiseRejectionHandler.
The function is now called from eventLoopTick.
- The promiseRejectMacrotaskCallback no longer exists, as this is
automatically handled in eventLoopTick.
- ops.op_dispatch_exception now takes a second parameter: in_promise.
The preferred way to call this op is now reportUnhandledException or
reportUnhandledPromiseRejection.
