The map field has been empty for years now and we don't want the emit
file to be exposed so it allows us to iterate on making the cache
faster. Additionally, it's racy/unreliable to rely on this information.
Instead, people should emit the TS files themselves using tools like
deno_emit, typescript, esbuild, etc.

info: Deno doesn't support CommonJS modules without `.cjs` extension.
hint: Rewrite this module to ESM or change the file extension to `.cjs`.
```
This commit adds support for executing top-level `.cjs` files,
as well as import `.cjs` files from within npm packages.
This works only for `.cjs` files, the contents of sibling `package.json`
are not consulted for the `"type"` field.

This commit adds:
- `addAbortListener` in `node:events`
- `aborted` in `node:util`
- `execPath` and `execvArgs` named export from `node:process`
- `getDefaultHighWaterMark` from `node:stream`
The `execPath` is very hacky - because module namespaces can not have
real getters, `execPath` is an object with a `toString()` method that on
call returns the actual `execPath`, and replaces the `execPath` binding
with the string. This is done so that we don't require the `execPath`
permission on startup.
Running a file like:
```
import "@std/dotenv/load";
```
Without a mapping in `imports` field of `deno.json` or `dependencies` of
`package.json`
will now error out with a hint:
```
error: Relative import path "@std/dotenv/load" not prefixed with / or ./ or ../
hint: Try running `deno add @std/dotenv/load`
at [WILDCARD]bare_specifier_without_import/main.ts:1:8

This commit changes when to cause the hostname substition of `0.0.0.0` ->
`localhost`.
Currently we substitute `localhost` to the hostname on windows before
calling `options.onListen`, which prevents the users to do more advanced
thing using hostname string like
https://github.com/denoland/std/issues/5558. This PR changes it not to
substitute it when the user provide `onListen` callback.

This change fixes the handling of upgraded socket from `node:http` module.
In `op_node_http_fetch_response_upgrade`, we create DuplexStream paired
with `hyper::upgrade::Upgraded`. When the connection is closed from the
server, the read result from `Upgraded` becomes 0. However because we
don't close the paired DuplexStream at that point, the Socket object in
JS side keeps alive even after the server closed. That caused the issue
#20179
This change fixes it by closing the paired DuplexStream when the
`Upgraded` stream returns 0 read result.
closes #20179
This allows using npm deps of jsr deps without having to add them to the
root package.json.
Works by taking the package requirement and scanning the
`node_modules/.deno` directory for the best matching package, so it
relies on deno's node_modules structure.
Additionally to make the transition from package.json to deno.json
easier, Deno now:
1. Installs npm deps in a deno.json at the same time as installing npm
deps from a package.json.
2. Uses the alias in the import map for `node_modules/<alias>` for
better package.json compatiblity.
These now works:
```
$ deno add @std/dotenv/load
$ deno add npm:preact/hooks
```
Previously we were erroring out, because this is a "package reference"
including
a subpath.

`--allow-run` even with an allow list has essentially been
`--allow-all`... this locks it down more.
1. Resolves allow list for `--allow-run=` on startup to an absolute
path, then uses these paths when evaluating if a command can execute.
Also, adds these paths to `--deny-write`
1. Resolves the environment (cwd and env vars) before evaluating
permissions and before executing a command. Then uses this environment
to evaluate the permissions and then evaluate the command.
This PR serves as a part of #22907 .

Remove `--allow-hrtime` and `--deny-hrtime`. We are doing this because
it is already possible to get access to high resolution timers through
workers and SharedArrayBuffer.

Note: this is implemented on Deploy. However, according to @magurotuna,
a thin compatibility layer might be in the works that'd prevent
breakages for PRs such as this one.

`deno bundle` now produces:
```
error: ⚠️ `deno bundle` was removed in Deno 2.
See the Deno 1.x to 2.x Migration Guide for migration instructions: https://docs.deno.com/runtime/manual/advanced/migrate_deprecations
```
`deno bundle --help` now produces:
```
⚠️ `deno bundle` was removed in Deno 2.
See the Deno 1.x to 2.x Migration Guide for migration instructions: https://docs.deno.com/runtime/manual/advanced/migrate_deprecations
Usage: deno bundle [OPTIONS]
Options:
-q, --quiet Suppress diagnostic output
--unstable Enable all unstable features and APIs. Instead of using this flag, consider enabling individual unstable features
To view the list of individual unstable feature flags, run this command again with --help=unstable

Before:
```
$ deno upgrade v1.xx

After:
```
$ deno upgrade v1.xx
error: Invalid version passed (v1.xx)
Example usage:
deno upgrade | deno upgrade 1.46 | deno upgrade canary

Also updates help text to use "shorthand version" without flags, but a
positional arg.
This commit effectively turns Deno into Deno 2.0.
This is done by forcing `DENO_FUTURE=1` env var, that was available in
the past few months to try Deno 2 changes.
This commit contains several breaking changes scheduled for Deno 2:
- all deprecated JavaScript APIs are not available any more, mostly
`Deno.*` APIs
- `window` global is removed
- FFI, WebGPU and FS APIs are now stable and don't require
`--unstable-*` flags
- import assertions are no longer supported
- "bring your own node modules" is enabled by default
This is the first commit in a series that are scheduled before the Deno
2 release.
Follow up work is tracked in
https://github.com/denoland/deno/issues/25241.

This is blocking https://github.com/denoland/deno/pull/25213.
Turns out a bunch of FS APIs are completely broken because they
use RIDs (resource IDs) instead of FDs (file descriptors).
Fixes several tests blocking https://github.com/denoland/deno/pull/25213
by replacing `window` global that is gone in Deno 2 with `globalThis`.
Also adjusted a few tests using deprecated `rid` field.
Turns out we only virtualized it so one could have a `Console` property,
and the other one not. We can just make this `console.Console` available
everywhere.
Stores normalized version constraints in the lockfile, which will
improve reproducibility and will fix a bug with duplicate specifiers
ending up in the lockfile. Also, gets rid of some duplicate data in the
specifiers area of the lockfile.
Part of #20613.
If a node addon is using the legacy `napi_module_register` on ctor
approach to module registration, we have to store the registered module
so that other threads can load the addon (because `napi_module_register`
will only be called once per process).
This commit remove `--lock-write` that was deprecated in v1.45 release.

Fixes #23281. Part of #20613.
We were emitting the `online` event in the constructor, so the caller
could never receive it (since there was no time for them to add a
listener). Instead, emit the event where it's intended – after the
worker is initialized.
---
After this parcel no longer freezes, but still will fail due to other
bugs (which will be fixed in other PRs)
Fix task names containing a colon not being found with `deno run`. We
were only checking for a `module not found` error message, but strings
containing a colon throw a different error.
Fixes https://github.com/denoland/deno/issues/25232
- Add missing exports to `node:cluster`
- Fix default export not being an instance of `EventEmitter`
- Fix aliasing of properties
- Fix `disconnected` -> `disconnect` export naming
This makes `log4js` work in Deno. `karma` starts too, but somehow the
server isn't responding. That looks like a different issue.
Fixes https://github.com/denoland/deno/issues/24858
This commit enables the `log` feature for the `tracing` crate.
This allows us to examine additional detailed logs emitted by third party crates
that use `tracing` crate for logging by setting `RUST_LOG` env var or passing
`-L` option in command line.
Closes #25045
Fixes #24607.
This PR makes the logic that caches top level dependencies (things
present in import map) smarter, so we handle JSR dependencies without
root exports.
This commit deprecates "import assertions" proposal that has been
replaced with "import attributes".
Any time an import assertion is encountered a warning will be printed
to the terminal. This warning will be printed for both local and
remote files (ie. user code and dependencies).
Import assertions support will be removed in Deno 2.
Permission flags are unified in a clearer and concise output.
Unstable flags are hidden by default with exception of the `unstable`
flag itself. the remaining unstable flags can be seen with a
`--help=unstable`.
This also cleans up to show unstable flags only for subcommands that
actually need them.
Also sorts flags alphabetically, and gorups various flags together in a
set of categories.

This PR addresses a regression introduced in
https://github.com/denoland/deno/pull/25021 that would cause the
`req.url` parameter in Node's http server to always be a single
character instead of the expected value. The regression was caused by
effectively calling `.indexOf()` on an empty string and thus passing the
wrong index for slicing.
```js
"".indexOf("/") // -> -1
request.url.slice(-1) // effectively only giving us the last character
```

PrismJS uses `WorkerGlobalScope` and `self` for detecting browser's Web
Worker context:
59e5a34713/prism.js (L11)
Now the detection logic above is broken when it's imported from Deno's
Web Worker context because we only hide `self` (Prism assumes when
`WorkerGlobalScope` is available, `self` is also available).
This change fixes the above by also hiding `WorkerGlobalScope` global in
Node compat mode.
closes #25008
My fix in #25030 was buggy, I forgot to pass the `byteOffset` and
`byteLength`. Whoops.
I also discovered that fs.read was not respecting the `offset` argument,
and we were constructing a new `Buffer` for the callback instead of just
passing the original one (which is what node does, and the @types/node
definitions also indicate the callback should get the same type).
Fixes #25028.
This change improves the Node.js compatibility in managed npm resolution
mode by disabling the discovery of `node_modules` when the
main specifier is inside of `DENO_DIR`.

MacOS tends to not distribute evenly, so just don't assert that requests
were served by > 1 worker on mac.
Also added a check that all workers start, so we at least check that on
macos.
From upgrading `deno_lint`.
Previously if you had a node project that used a bunch of node globals
(`process.env`, etc), you would have to fix the errors by hand. This PR
includes a new lint that detects usages of node globals (`process`,
`setImmediate`, `Buffer`, etc.) and provides an autofix to import the
correct value. For instance:
```ts
// main.ts
const _foo = process.env.FOO;
```
`deno lint` gives you
```ts
error[no-node-globals]: NodeJS globals are not available in Deno
--> /home/foo.ts:1:14
|
1 | const _foo = process.env.FOO;
| ^^^^^^^
= hint: Add `import process from "node:process";`
docs: https://lint.deno.land/rules/no-node-globals
Found 1 problem (1 fixable via --fix)
Checked 1 file
```
And `deno lint --fix` adds the import for you:
```ts
// main.ts
import process from "node:process";
const _foo = process.env.FOO;
```
