This commit adds `--eval` flag to `deno task` subcommand.
This flag allows to evaluate provided "task name" as a task itself,
effectively allowing to use `deno_task_shell` from the command line.
Also fixes shebang parsing for `node_modules/.bin/` entries to handle
`#!/usr/bin/node -S node` in addition to `#!/usr/bin/node node`.
Closes https://github.com/denoland/deno/issues/26918
We should track dependencies in `jsxImportSource`,
`jsxImportSourceTypes`, and `types`.
That way, for example, if someone removes or changes the
`jsxImportSource` then we can remove those items from the lockfile.
Support for Wasm modules.
Note this implements the standard where the default export is the
instance (not the module). The module will come later with source phase
imports.
```ts
import { add } from "./math.wasm";
console.log(add(1, 2));
```
```
> deno compile --allow-read=. --include data-file.txt main.js
```
This only applies to files on the filesystem. For remote modules, that's
going to have to wait for `import ... from "./data.txt" with { "type":
"bytes" }` or whatever it will be.
The issue was this package had an import like: `".//index.js"` and we
resolved that as specified, but node normalizes it to `"./index.js"` so
we have to copy node.
This commit adds support for "dependencies" in `deno task` subcommand:
```jsonc
{
"tasks": {
"build": "deno run -RW build.ts",
"generate": "deno run -RW generate.ts",
"serve": {
"command": "deno run -RN server.ts",
"dependencies": ["build", "generate"]
}
}
}
```
Executing `deno task serve` will first execute `build` and `generate`
tasks (in parallel) and once both complete the `serve` task will be executed.
Number of tasks run in parallel is equal to the no of cores on the
machine, and respects `DENO_JOBS` env var if one is specified.

This PR removes the public Deno.tracing.Span API.
We are not confident we can ship an API that is
better than the `@opentelemetry/api` API, because
V8 CPED does not support us using `using` to
manage span context. If this changes, we can
revisit this decision. For now, users wanting
custom spans can instrument their code using
the `@opentelemetry/api` API and `@deno/otel`.
This PR also speeds up the OTEL trace generation
by a 30% by using Uint8Array instead of
strings for the trace ID and span ID.
Adds a lazily created code cache to `deno compile` by default.
The code cache is created on first run to a single file in the temp
directory and is only written once. After it's been written, the code
cache becomes read only on subsequent runs. Only the modules loaded
during startup are cached (dynamic imports are not code cached).
The code cache can be disabled by compiling with `--no-code-cache`.
These tests are hitting a remote server which sometimes starts failing
randomly on CI.
They need to be rewritten to use a local server and have `/etc/hosts`
setup that remaps relevants URLs.
Closes #26425
## Overview
This PR adds support for specifying multiple environment files as
arguments when using the Deno CLI. Subsequent files override
pre-existing variables defined in previous files.
If the same variable is defined in the environment and in the file, the
value from the environment takes precedence.
## Example Usage
```bash
deno run --allow-env --env-file --env-file=".env.one" --env-file=".env.two" script.ts
```

This commit adds `Deno.jupyter.image` API to display PNG and JPG images:
```
const data = Deno.readFileSync("./my-image.jpg");
Deno.jupyter.image(data);
Deno.jupyter.image("./my-image.jpg");
```
This commit changes three aspects of `deno task`:
1. Tasks can now be written using object notation like so:
```jsonc
{
"tasks": {
"foo": "deno run foo.js",
"bar": {
"command": "deno run bar.js"
}
}
```
2. Support for comments for tasks is now removed. Comments above tasks
will
no longer be printed when running `deno task`.
3. Tasks written using object notation can have "description" field that
replaces
support for comments above tasks:
```jsonc
{
"tasks": {
"bar": {
"description": "This is a bar task"
"command": "deno run bar.js"
}
}
```
```
$ deno task
Available tasks:
- bar
// This is a bar task
deno run bar.js
```
Pulled most of the changes from
https://github.com/denoland/deno/pull/26467 to
support "dependencies" in tasks. Additionally some cleanup was performed
to make code easier to read.

Improving the breadth of collected data, and ensuring that the collected
data is more likely to be successfully reported.
- Use `log` crate in more places
- Hook up `log` crate to otel
- Switch to process-wide otel processors
- Handle places that use `process::exit`
Also adds a more robust testing framework, with a deterministic tracing
setting.

This commit makes comments in code snippets in JSDoc or markdown
preserved when they are executed as tests. In particular, this is needed
to get TypeScript special comments such as `@ts-ignore` or
`@ts-expect-error` to work correctly.
Fixes #26728
This will respect `"type": "commonjs"` in a package.json to determine if
`.js`/`.jsx`/`.ts`/.tsx` files are CJS or ESM. If the file is found to
be ESM it will be loaded as ESM though.
Initial import of OTEL code supporting tracing. Metrics soon to come.
Implements APIs for https://jsr.io/@deno/otel so that code using
OpenTelemetry.js just works tm.
There is still a lot of work to do with configuration and adding
built-in tracing to core APIs, which will come in followup PRs.

Fixes #26677
Some packages (like supabase) declare bin entries that don't exist until
lifecycle scripts are run. For instance, the lifecycle script downloads
a binary file which serves as a bin entrypoint.
Unfortunately you can't just defer setting up the bin entries until
after lifecycle scripts have run, because the scripts may rely on them.
I looked into this, and PNPM just re-links bin entries after running
lifecycle scripts. I think that's about the best we can do as well.
Note that we'll only re-setup bin entries for packages whose lifecycle
scripts we run. This should limit the performance cost, as typically a
given project will not have many lifecycle scripts (and of those, many
of them probably don't have bin entries to set up).

Fixes #25342.
Still not sure on the exact user agent to set (should it include
`node`?).
After this PR, here's the state of running some `create-*` packages
(just ones I could think of off the top of my head):
| package | prints/runs/suggests deno install | notes |
| ---------------- | ------------- | ------ |
| `create-next-app` | ❌ | falls back to npm, needs a PR
([code](c32e280209/packages/create-next-app/helpers/get-pkg-manager.ts (L3)))
| `sv create` | ❌ | uses `package-manager-detector`, needs a PR
([code](https://github.com/antfu-collective/package-manager-detector/tree/main))
| `create-qwik` | ✅ | runs `deno install` but suggests `deno start`
which doesn't work (should be `deno task start` or `deno run start`)
| `create-astro` | ✅ | runs `deno install` but suggests `npm run dev`
later in output, probably needs a PR
| `nuxi init` | ❌ | deno not an option in dialog, needs a PR
([code](f04e2e8944/src/commands/init.ts (L96-L102)))
| `create-react-app` | ❌ | uses npm
| `ng new` (`@angular/cli`) | ❌ | uses npm
| `create-vite` | ✅ | suggests working deno commands 🎉
| `create-solid` | ❌ | suggests npm commands, needs PR
It's possible that fixing `package-manager-detector` or other packages
might make some of these just work, but haven't looked too carefully at
each

I'm not exactly sure how this case comes about (I tried to write tests
for it but couldn't manage to reproduce it), but what happens is the
parent filename ends up null, and we bail out of resolving the specifier
in package exports.
I've checked, and in node the parent filename is also null (so that's
not a bug on our part), but node continues to resolve even in that case.
So this PR should match node's behavior more closely than we currently
do.
Spend some time stepping through the npm client code and noticed that
the bearer token was different from ours. They do some double encoding
and @dsherret helped me in matching the encoding behavior.
Fixes https://github.com/denoland/deno/issues/26033
Fixes https://github.com/denoland/deno/issues/26509.
Ended up being a `deno_graph` bug causing the error to surface. This PR
updates `deno_graph` to pick up the fix and reverts the temporary
workaround that skipped JSON exports.
While testing, I found out that light-my-request relies on
`ServerResponse.connection`, which is deprecated, so I added that and
`socket`, the non deprecated property.
It also relies on an undocumented `_header` property, apparently for
[raw header
processing](https://github.com/fastify/light-my-request/blob/v6.1.0/lib/response.js#L180-L186).
I added it as an empty string, feel free to provide other approaches.

Fixes playwright on linux, as reported in
https://github.com/denoland/deno/issues/16899#issuecomment-2378268454.
The issue was that we were opening the socket in nonblocking mode, which
meant that subprocesses trying to use it would get a `EWOULDBLOCK` error
(unexpectedly). The fix here is to only set nonblocking mode on our end
(which we need to use asynchronously)
Fixes #26498.
This was a sort of intentional decision originally, as I wanted to avoid
caching extra files that may not be needed. It seems like that behavior
is unintuitive, so I propose we cache all of the exports of listed jsr
packages when you run a bare `deno install`.
This commit makes sure that `deno add`, `deno install` and `deno remove`
update the lockfile if only `package.json` file is present.
Fixes https://github.com/denoland/deno/issues/26270
1. Respects the formatting of the file (ex. keeps four space indents or
tabs).
2. Handles editing of comments.
3. Handles trailing commas.
4. Code is easier to maintain.
This PR fixes the issue where mapped specifiers in a workspace member
would never be found. Only mapped paths from the workspace root would
resolve.
This was caused by always passing the workspace root url to the import
map resolver instead of the workspace member one.

We weren't normalizing the headers to lower case, so code that attempted
to delete the `Content-Length` header (but used a different case) wasn't
actually removing the header.
partially unblocks #25470
This PR aligns the resolution of `localhost` hostname to Node.js
behavior.
In Node.js `dns.lookup("localhost", (_, addr) => console.log(addr))`
prints ipv6 address `::1`, but it prints ipv4 address `127.0.0.1` in
Deno. That difference causes some errors in the work of enabling
`createConnection` option in `http.request` (#25470). This PR fixes the
issue by aligning `dns.lookup` behavior to Node.js.
This PR also changes the following behaviors (resolving TODOs):
- `http.createServer` now listens on ipv6 address `[::]` by default on
linux/mac
- `net.createServer` now listens on ipv6 address `[::]` by default on
linux/mac
These changes are also alignments to Node.js behaviors.
`napi_call_function` should use our equiv of NAPI_PREAMBLE (`&mut Env`
instead of `*mut Env`) since it needs to set error codes based on
whether the body of the function raised a JS exception.

When using the `--unstable-detect-cjs` flag or adding `"unstable":
["detect-cjs"]` to a deno.json, it will make a JS file CJS if the
closest package.json contains `"type": "commonjs"` and the file is not
an ESM module (no TLA, no `import.meta`, no `import`/`export`).
