Adds a `parallel` flag to `deno serve`. When present, we spawn multiple
workers to parallelize serving requests.
```bash
deno serve --parallel main.ts
```
Currently on linux we use `SO_REUSEPORT` and rely on the fact that the
kernel will distribute connections in a round-robin manner.
On mac and windows, we sort of emulate this by cloning the underlying
file descriptor and passing a handle to each worker. The connections
will not be guaranteed to be fairly distributed (and in practice almost
certainly won't be), but the distribution is still spread enough to
provide a significant performance increase.

This commit makes `fetch` error messages include source and destination TCP
socket info i.e. port number and IP address for better debuggability.
Closes #24922
- upgrade to v8 12.8
- optimizes DataView bigint methods
- fixes global interceptors
- includes CPED methods for ALS
- fix global resolution
- makes global resolution consistent using host_defined_options.
originally a separate patch but due to the global interceptor bug it
needs to be included in this pr for all tests to pass.
This is in preparation for extracting out node resolution code from
ext/node (which is something I'm going to do gradually over time).
Uses https://github.com/denoland/deno_package_json
This is the release commit being forwarded back to main for 1.45.3

This PR will bump the deno_cache_dir dependency from 0.10.0 to 0.10.2.
This will make the cache manifest at manifest.json more deterministic
(see denoland/deno_cache_dir#53 )

Originally landed in
f6fd6619e7.
Reverted in https://github.com/denoland/deno/pull/24574.
This reland contains a fix that sends "Accept: */*" header for calls made
from "FileFetcher". Absence of this header made downloading source code
from JSR broken. This is tested by ensuring this header is present in the
test server that servers JSR packages.

This makes bare specifiers for npm packages work when inside a
workspace, which emulates the same behaviour as when there's a
node_modules directory. The bare specifier can be overwritten by
specifying an import map entry or package.json dependency entry.

Closes #24605
This commit re-implements `ext/fetch` and all dependent crates
using `hyper` and `hyper-util`, instead of `reqwest`.
The reasoning is that we want to have greater control and access
to low level `hyper` APIs when implementing `fetch` API as well
as `node:http` module.

This is a temporary fix, which is not perfect - specifying
`--import-map`
will break resolution of packages defined in `workspace` setting, but
erroring on `--import-map` currently causes regression in code that
worked fine in v1.44.x.
This commit fixes memory leak described in
https://github.com/denoland/deno/issues/24380.
This is done by upgrading following crates:
- deno_ast
- deno_graph
- eszip
- dprint-plugin-typescript
- deno_lint
- deno_doc
- deno_emit
Adds support for running npm package lifecycle scripts, opted into via a
new `--allow-scripts` flag.
With this PR, when running `deno cache` (or `DENO_FUTURE=1 deno
install`) you can specify the `--allow-scripts=pkg1,pkg2` flag to run
lifecycle scripts attached to the given packages.
Note at the moment this only works when `nodeModulesDir` is true (using
the local resolver).
When a package with un-run lifecycle scripts is encountered, we emit a
warning suggesting things may not work and to try running lifecycle
scripts. Additionally, if a package script implicitly requires
`node-gyp` and it's not found on the system, we emit a warning.
Extra things in this PR:
- Extracted out bits of `task.rs` into a separate module for reuse
- Added a couple fields to `process.config` in order to support
`node-gyp` (it relies on a few variables being there)
- Drive by fix to downloading new npm packages to test registry
---
TODO:
- [x] validation for allow-scripts args (make sure it looks like an npm
package)
- [x] make allow-scripts matching smarter
- [ ] figure out what issues this closes
---
Review notes:
- This adds a bunch of deps to our test registry due to using
`node-gyp`, so it's pretty noisy
This adds object config for the workspace config:
```json
{
"workspace": {
"members": ["./member-1", "./member-2"]
}
}
```
This is a more verbose version of `"workspace": ["./member-1",
"./member-2"]`. Although we don't need it at the moment, it makes the
naming of `"workspace"` more clear and leaves the object open for more
config in the future.
