- 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
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

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
```
❯ hyperfine --warmup 5 -p "rm -rf ~/Library/Caches/deno/check_cache_v2" "../../deno/target/release-lite/deno check main.ts" "deno check main.ts"
Benchmark 1: ../../deno/target/release-lite/deno check main.ts
Time (mean ± σ): 184.2 ms ± 2.2 ms [User: 378.3 ms, System: 48.2 ms]
Range (min … max): 181.5 ms … 189.9 ms 15 runs
Benchmark 2: deno check main.ts
Time (mean ± σ): 107.4 ms ± 1.2 ms [User: 155.3 ms, System: 23.9 ms]
Range (min … max): 105.3 ms … 109.6 ms 26 runs
Summary
deno check main.ts ran
1.72 ± 0.03 times faster than ../../deno/target/release-lite/deno check main.ts

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 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.
(extracted from https://github.com/denoland/deno/pull/27977)
https://nodejs.org/api/sqlite.html#databaseapplychangesetchangeset-options
```js
const sourceDb = new DatabaseSync(':memory:');
const targetDb = new DatabaseSync(':memory:');
sourceDb.exec('CREATE TABLE data(key INTEGER PRIMARY KEY, value TEXT)');
targetDb.exec('CREATE TABLE data(key INTEGER PRIMARY KEY, value TEXT)');
const session = sourceDb.createSession();
const insert = sourceDb.prepare('INSERT INTO data (key, value) VALUES (?, ?)');
insert.run(1, 'hello');
insert.run(2, 'world');
const changeset = session.changeset();
targetDb.applyChangeset(changeset);
// Now that the changeset has been applied, targetDb contains the same data as sourceDb.
```
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.

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.
Implements the `readOnly` option for `DatabaseSync`.
Permissions:
`--allow-read=test.db --allow-write=test.db` => all works
`--allow-read=test.db` => only `readOnly` dbs work, cannot create new db
Shows directory import and missing extension suggestions in error
messages similar but not exactly to node.
Closes #26802
