Closes https://github.com/denoland/deno/issues/25084
|
|
The check in `tty.WriteStream.prototype.hasColors()` was incorrect
leading to the
[`yoctocolors`](https://github.com/sindresorhus/yoctocolors) package not
printing any colors.
Fixes https://github.com/denoland/deno/issues/24407

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
```
Fixes https://github.com/denoland/deno/issues/25080

PrismJS uses `WorkerGlobalScope` and `self` for detecting browser's Web
Worker context:
https://github.com/PrismJS/prism/blob/59e5a3471377057de1f401ba38337aca27b80e03/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.

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.

1. Adds a new "license" field.
1. Adds this field by default when doing `deno init --lib`
|
|
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`.

This reverts commit 22a834ff5b4b312b8f91be8991f2b495d49fad2f.
Appears this commit might have broken tests on `main`.

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;
```

Linux/macos only currently.
Part of https://github.com/denoland/deno/issues/23524 (fixes it on
platforms other than windows).
Part of #16899 (fixes it on platforms other than windows).
After this PR, playwright is functional on mac/linux.

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 adds capability to format HTML, Svelte, Vue, Astro and Angular
files.
"--unstable-html" is required to format HTML files, and "--unstable-component"
flag is needed to format other formats. These can also be specified in the config
file.

This commit adds another test suite that runs all Deno unit tests
with `DENO_FUTURE=1` flag to ensure all APIs are working as
expected, once Deno 2 is released.

Uint8Array (#25030)
Part of #25028.
Our underlying read/write operations in `io` assume the buffer is a
Uint8Array, but we were passing in other typed arrays (in the case above
it was `Int8Array`).

There is no constructor code when creating an inspector `Session`
instance in Node. Also get rid of some symbols which should've been
private properties. This PR doesn't yet add any new implementations
though as these are mostly cosmetic changes.

|
For some reason we didn't register the `node:inspector` module, which
lead to a panic when trying to import it. This PR registers it.

This commit stabilizes HMR functionality and renames
`--unstable-hmr` to `--watch-hmr`. The `--unstable-hmr`
flag is still working, but hidden from the help output.
It will be removed in Deno 2.
Once https://github.com/denoland/deno/pull/24958 lands
we should improve grouping of `--watch` and `--watch-hmr`
flags.

This is commonly used to register loading non standard file types. But
some libs also register TS loaders which Deno supports natively, like
the npm `payload` package. This PR unblocks those.
