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.

Fixes an incredibly obscure bug that causes parcel's file watcher to not
get any file update notifications on macOS.
The issue was that the native addon was calling `napi_resolve_deferred`,
but when we resolved the promise, v8 was running microtasks
automatically. That executed JS, which called back into the native addon
and broke the addon's assumption that the call wouldn't be reentrant.
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.
Unlike in dprint, `single_quote` option is shared between all
formatters, so we shouldn't change this option when formatting
attributes in components. This PR fixes this.
This problem doesn't affect formatting HTML.
This commit remove `--lock-write` that was deprecated in v1.45 release.
Closes https://github.com/denoland/deno/issues/24167.

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
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.
- rewrite flag help
- use gray for indentation
- reorganize permission flags and split them up
- make help subcommand act like help flag
- `deno run` outputs list of tasks
- Fixes #25120
error handling for `deno run` in case of no config file being found
needs to be improved

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.
