To avoid the risk of port collisions during tests, we listen on port 0
and use that for both ends of the connections (for any tests we run in
this file).
Fixes #23179.
Fixes #22454.
Enables passing `{tokens: true}` to `parseArgs` and setting default
values for options.
With this PR, the observable framework works with deno out of the box
(no unstable flags needed).
The existing code was basically copied straight from node, so this PR
mostly just updates that (out of date) vendored code. Also fixes some
issues with error exports (before this PR, in certain error cases we
were attempting to construct error classes that weren't actually in
scope).
The last change (in the second commit) adds a small hack so that we
actually exercise the `test-parse-args.js` node_compat test, previously
it was reported as passing though it should have failed. That test now
passes.

When `DENO_FUTURE=1` env var is present, then BYONM
("bring your own node_modules") is enabled by default.
That means that is there's a `package.json` present, users
are expected to explicitly install dependencies from that file.

The `tools/node_compat/node` submodule has been moved to
`tests/node_compat/runner/suite` and the remaining files within
`tools/node_compat` to `tests/node_compat/runner`.
Most of the changes are of the header within `tests/node_compat/test`
files. The `setup` and `test` tasks within `tests/node_comapt` execute
successfully.

The permission prompt doesn't wait for quiescent input, so someone
pasting a large text file into the console may end up losing the prompt.
We enforce a minimum human delay and wait for a 100ms quiescent period
before we write and accept prompt input to avoid this problem.
This does require adding a human delay in all prompt tests, but that's
pretty straightforward. I rewrote the locked stdout/stderr test while I
was in here.
Was doing a bit of debugging on why some stuff is not working in a
personal project and ran a quick debug profile and saw it cloning the
pkg json a lot. We should put this in an Rc.
Unused locals and parameters don't make sense to surface in remote
modules. Additionally, fast check can cause these kind of diagnostics
when publishing, so they should be ignored.
Closes #22959
Was investigating a separate stack overflow (that I've now found in the
node resolution code) and came across this. We should avoid recursion
(this is very old code).
There's a TOCTOU issue that can happen when selecting unused ports for
the server to use (we get assigned an unused port by the OS, and between
then and when the server actually binds to the port another test steals
it). Improve this by checking if the server existed soon after setup,
and if so we retry starting it. Client connection can also fail
spuriously (in local testing) so added a retry mechanism.
This also fixes a hang, where if the server exited (almost always due to
the issue described above) before we connected to it, attempting to
connect our client ZMQ sockets to it would just hang. To resolve this, I
added a timeout so we can't wait forever.
This PR introduces the ability to exclude certain paths from the file watcher
in Deno. This is particularly useful when running scripts in watch mode,
as it allows developers to prevent unnecessary restarts when changes are
made to files that do not affect the running script, or when executing
scripts that generate new files which results in an infinite restart
loop.

In preparation for upcoming changes to `deno install` in Deno 2.
If `-g` or `--global` flag is not provided a warning will be emitted:
```
⚠️ `deno install` behavior will change in Deno 2. To preserve the current behavior use `-g` or `--global` flag.
```
The same will happen for `deno uninstall` - unless `-g`/`--global` flag
is provided
a warning will be emitted.

This commit changes "deno init" subcommand to use "jsr:" specifier for
standard library "assert" module. It is unversioned, but we will change
it to `@^1` once `@std/assert` release version 1.0.
This allows us to start decoupling `deno` and `deno_std` release. The
release scripts have been updated to take that into account.
Fixes #23053.
Two small bugs here:
- the existing condition for printing out the group header was broken.
it worked in the reproducer (in the issue above) without filtering only
by accident, due to setting `self.has_ungrouped = true` once we see the
warmup bench. Knowing that we sort benchmarks to put ungrouped benches
first, there are only two cases: 1) we are starting the first group 2)
we are ending the previous group and starting a new group
- when you passed `--filter` we were applying that filter to the warmup
bench (which is not visible to users), so we suffered from jit bias if
you were filtering (unless your filter was `<warmup>`)
TLDR;
Running
```bash
deno bench main.js --filter="G"
```
```js
// main.js
Deno.bench({
group: "G1",
name: "G1-A",
fn() {},
});
Deno.bench({
group: "G1",
name: "G1-B",
fn() {},
});
```
