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.
This commit changes `deno upgrade` subcommand to accept
a positional argument that can be either a version, release channel
name or a git hash, making invocations of `deno upgrade` much
more concise:
```
# before
$ deno upgrade --version 1.46.0
# after
$ deno upgrade 1.46.0
```
```
# before
$ deno upgrade --canary
# after
$ deno upgrade canary
```
```
# specific canary version before
$ deno upgrade --canary --version f042c39180
# after
$ deno upgrade f042c39180
```
Old flags are still supported, but hidden from the help output.
- Update ffi turbocall to use revised fast call api
- Remove `v8_version` function calls
- `*mut OwnedIsolate` is no longer stored in OpCtx gotham store
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 commit fixes computation of the latest available version
by taking into account which release channel the current
binary is on.
Before this commit, if user was on "RC" channel, calling
`deno upgrade` would not switch back to the "stable"
channel.
This commits add a CI script that allows to promote a certain
canary build to a "Release Candidate" release.
This is done using `libsui` and `patchver` utilities.
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`.
closes #22732
closes #24589
This commit rewrites the internal `version` module that exported
various information about the current executable. Instead of exporting
several consts, we are now exporting a single const structure that
contains all the necessary information.
This is the first step towards cleaning up how we use this information
and should allow us to use SUI to be able to patch this information
in already produced binary making it easier to cut new releases.

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;
```
In preparation for https://github.com/denoland/deno/pull/25014, this
commit removes public `is_canary()` method and instead uses an enum
`ReleaseChannel` to be able to designate more "kinds" of builds.
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.
Close #25015
This commit fixes output of `deno upgrade` subcommand,
by displaying proper version numbers. Before this PR we were
prepending "v" before the canary version hash, which was
obviously wrong.
This commit changes how system certificates are loaded on startup.
Instead of hard erroring if a certificate can't be decoded, we are now
printing a warning and bumping a hex representation of the certificate
and continue execution.

These errors are caused by the fact that the test server doesn't have an
endpoint to return
RC releases. Which in turn causes an error to be raised which later just
short-circuits logic
for checking the version and storing it in file. Since fetching from a
remote host is always
fallible I elected to just return an empty vec of "rc" versions instead
of erroring. This might
lead to a slight mismatch in some situation when the request actually
failed and user is
prompted that there's a new canary version, but that is better than not
displaying
prompt at all. This issue will be fixed more robustly once we move to
using SUI for
specifying version of the binary.
This commit adds the "--rc" flag to "deno upgrade" subcommand.
This flag allows to upgrade to the latest "release candidate" release.
The update checker was also updated to take this into account.
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 PR integrates [Malva](https://github.com/g-plane/malva) into `deno

This PR ensures that we forward a `rename` event in our file watcher.
The rust lib we use combines that with the `modify` event.
This fixes a compatibility issue with Node too, which sends the `rename`
event as well.
Fixes https://github.com/denoland/deno/issues/24880
This PR updates `deno run` to fallback to executing tasks when there is
no script with the specified name. If there are both script and a task
with the same name then `deno run` will prioritise executing the script.
This moves YAML formatting behind an unstable flag for Deno 1.46. This
will make it opt-in to start and then we can remove the flag to make it
on by default in version of Deno after that.
This can be specified by doing `deno fmt --unstable-yaml` or by
specifying the following in a deno.json file:
```json
{
"unstable": ["fmt-yaml"]
}
```
Uses [sui](https://github.com/littledivy/sui) to inject metadata as a
custom section in the denort binary.
Metadata is stored as a Mach-O segment on macOS and PE `RT_RCDATA`
resource on Windows.

This PR resolves a handful of issues with child_process IPC. In
particular:
- We didn't support sending typed array views over IPC
- Opening an IPC channel resulted in the event loop never exiting
- Sending a `null` over IPC would terminate the channel
- There was some UB in the read implementation (transmuting an `&[u8]`
to `&mut [u8]`)
- The `send` method wasn't returning anything, so there was no way to
signal backpressure (this also resulted in the benchmark
`child_process_ipc.mjs` being misleading, as it tried to respect
backpressure. That gave node much worse results at larger message sizes,
and gave us much worse results at smaller message sizes).
- We weren't setting up the `channel` property on the `process` global
(or on the `ChildProcess` object), and also didn't have a way to
ref/unref the channel
- Calling `kill` multiple times (or disconnecting the channel, then
calling kill) would throw an error
- Node couldn't spawn a deno subprocess and communicate with it over IPC
