- upgrade v8 to 13.4
- turbocall conversion for arraybuffers is now much more complex, so use
cranelift
- misc updates for deprecated fns
- v8 default stack size is too small now, causing stack overflow
exceptions in some tests
- add syscall shim to support new syscall in old sysroot
Cache busts the http cache when the lockfile integrity doesn't match
what's in the cache. This will help when someone's lockfile is in line
with the remote server, but their local cache isn't.
Supports `deno task --frozen=false some_task`, which is necessary
because with `"nodeModulesDir": "auto"` or `"global"` (the default with
no package.json) we do an auto-install of npm packages.
Closes https://github.com/denoland/deno/issues/28070
In particular this helps startup of the TSC isolate because
`00_typescript.js` can use the code cache.
Overall, this offsets a fair bit of the hit we took when we removed the
TSC snapshot.

adds tracing and opentelemetry exporting to the LSP.
enable it in `.vscode/settings.json` (or wherever you configure the
LSP), like
```
{
"deno.tracing": true
}
```
which will by default export opentelemetry traces to `localhost:4317`
or
```
{
"deno.tracing": {
// all fields optional
"collector": "openTelemetry" (default) | "logging" (output in lsp log window)
"collectorEndpoint": "http://localhost:4318" (for opentelemetry)
"enable": true | false,
"filter": "info" // defaults to "info", but can be any span filter
}
}
```
---
a full working setup would be
1: Run jaeger (an opentelemetry collector with a nice UI):
```
docker run --rm -p 16686:16686 -p 4317:4317 jaegertracing/jaeger
```
2. Enable in .vscode/settings.json
```
{
"deno.tracing": true
}
```
3. Restart LSP (right now it only will start the opentelemetry exporter
on LSP startup)
3. open `http://localhost:16686` in your browser

This commit changes the TS host implementation
in the LSP to use the same snapshot as the runtime worker
and web worker use.
This is due to upcoming V8 upgrade that might require
that all isolates in the same process use the exact same
snapshot.
Removes the TSC snapshot to unblock the V8 upgrade (which enables shared
RO heap, and is incompatible with multiple snapshots).
this compresses the sources and declaration files as well, which leads
to a roughly 4.2MB reduction in binary size.
this currently adds about 80ms to deno check times, but code cache isn't
wired up for the extension code (namely `00_typescript.js`) yet

This commit removes the docs URL for diagnostics coming
from JS plugins. Before, we mistakenly printed
URLs pointing to `docs.deno.com`, even though they did not
exist.
An ability to actually specify a custom URL for plugin rules,
will be added in a follow up PR.
This commit fixes racy condition in lint plugins
that could have caused diagnostics for another
file to be printed for completely unrelated file.
With this change, a oneshot channel is used
to receive diagnostics for a file, which ensures
that the caller will receive diagnostics for itself.
This clears the diagnostics whenever a file is about to run. For
example, what could previously occur is an error and the diagnostics
would be leftover from the previous run.
Noticed that the LSP might panic during serialization when working on a
file with a syntax error.
This PR changes the serialization so that invalid nodes are simply
serialized to the invalid node `0`. The plugin code treats the node with
id `0` as an invalid node and will ignore it during visiting.
I'm not sure how to write a test for the LSP.
This PR fixes deviations in our AST format compared to TSEStree. They
are mostly a leftover for when I first started working on it and based
it off of babel instead.
One of the key changes why the changeset is a bit bigger is that
TSEStree uses `undefined` instead of `null` as the empty value for type
nodes. This is likely influenced by `tsc` which use `undefined`
everywhere. The rest of the nodes use `null` though. It's a little
weird, but for now it might be better to align.

Not sure what our handling of unstable properties in `deno.json` is.
This PR adds it to the config schema.

This commit adds an unstable lint plugin API.
Plugins are specified in the `deno.json` file under
`lint.plugins` option like so:
```
{
"lint": {
"plugins": [
"./plugins/my-plugin.ts",
"jsr:@deno/lint-plugin1",
"npm:@deno/lint-plugin2"
]
}
}
```
The API is considered unstable and might be subject
to changes in the future.
Plugin API was modelled after ESLint API for the
most part, but there are no guarantees for compatibility.
The AST format exposed to plugins is closely modelled
after the AST that `typescript-eslint` uses.
Lint plugins use the visitor pattern and can add
diagnostics like so:
```
export default {
name: "lint-plugin",
rules: {
"plugin-rule": {
create(context) {
return {
Identifier(node) {
if (node.name === "a") {
context.report({
node,
message: "should be b",
fix(fixer) {
return fixer.replaceText(node, "_b");
},
});
}
},
};
},
},
},
} satisfies Deno.lint.Plugin;
```
Besides reporting errors (diagnostics) plugins can provide
automatic fixes that use text replacement to apply changes.

interactively select which packages to upgrade. a future improvement
could be to add a way to select the version as well, though not sure how
valuable that would be.
This PR adds the `--permit-no-files` cli options to the `bench`
subcommand. This will cause `deno bench --permit-no-files` to not return
an error when no bench files where found.
