Basically just update deno_lockfile, deno_npm, and eszip, and then adapt
to those changes. The main changes were the removal of the lockfile v4
resolution snapshot loading, and a terser formatting for the `os` and
`cpu` fields in the lockfile.
Fixes two issues:
- If a cached packument was out of date and missing a version from the
lockfile, we would fail. Instead we should try again with a forced
re-fetch
- We weren't threading through the workspace patch packages correctly
This PR updates the behavior of `deno test --coverage` option. Now if
`--coverage` option is specified, `deno test` command automatically
shows summary report in the terminal, and generates the lcov report in
`$coverage_dir/lcov.info` and html report in `$coverage_dir/html/`
This change also adds `--coverage-raw-data-only` flag, which prevents
the above reports generated, instead only generates the raw json
coverage data (which is the same as current behavior)
This commit enabled [explicit resource management]
(https://github.com/tc39/proposal-explicit-resource-management)
proposal for JavaScript code.
This is done by upgrading `deno_ast` to a version that no longer
transpiles TS files with `using` keyword, and instead enables
a V8 flag that provides native support.

Fixes#27264. Fixes https://github.com/denoland/deno/issues/28161.
Currently the new lockfile version is gated behind an unstable flag
(`--unstable-lockfile-v5`) until the next minor release, where it will
become the default.
The main motivation here is that it improves startup performance when
using the global cache or `--node-modules-dir=auto`.
In a create-next-app project, running an empty file:
```
❯ hyperfine --warmup 25 -N --setup "rm -f deno.lock" "deno run --node-modules-dir=auto -A empty.js" "deno-this-pr run --node-modules-dir=auto -A empty.js" "deno-this-pr run --node-modules-dir=auto --unstable-lockfile-v5 empty.js" "deno run --node-modules-dir=manual -A empty.js" "deno-this-pr run --node-modules-dir=manual -A empty.js"
Benchmark 1: deno run --node-modules-dir=auto -A empty.js
Time (mean ± σ): 247.6 ms ± 1.7 ms [User: 228.7 ms, System: 19.0 ms]
Range (min … max): 245.5 ms … 251.5 ms 12 runs
Benchmark 2: deno-this-pr run --node-modules-dir=auto -A empty.js
Time (mean ± σ): 169.8 ms ± 1.0 ms [User: 152.9 ms, System: 17.9 ms]
Range (min … max): 168.9 ms … 172.5 ms 17 runs
Benchmark 3: deno-this-pr run --node-modules-dir=auto --unstable-lockfile-v5 empty.js
Time (mean ± σ): 16.2 ms ± 0.7 ms [User: 12.3 ms, System: 5.7 ms]
Range (min … max): 15.2 ms … 19.2 ms 185 runs
Benchmark 4: deno run --node-modules-dir=manual -A empty.js
Time (mean ± σ): 16.2 ms ± 0.8 ms [User: 11.6 ms, System: 5.5 ms]
Range (min … max): 14.9 ms … 19.7 ms 187 runs
Benchmark 5: deno-this-pr run --node-modules-dir=manual -A empty.js
Time (mean ± σ): 16.0 ms ± 0.9 ms [User: 12.0 ms, System: 5.5 ms]
Range (min … max): 14.8 ms … 22.3 ms 190 runs
Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet system without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options.
Summary
deno-this-pr run --node-modules-dir=manual -A empty.js ran
1.01 ± 0.08 times faster than deno run --node-modules-dir=manual -A empty.js
1.01 ± 0.07 times faster than deno-this-pr run --node-modules-dir=auto --unstable-lockfile-v5 empty.js
10.64 ± 0.60 times faster than deno-this-pr run --node-modules-dir=auto -A empty.js
15.51 ± 0.88 times faster than deno run --node-modules-dir=auto -A empty.js
```
When using the new lockfile version, this leads to a 15.5x faster
startup time compared to the current deno version.
Install times benefit as well, though to a lesser degree.
`deno install` on a create-next-app project, with everything cached
(just setting up node_modules from scratch):
```
❯ hyperfine --warmup 5 -N --prepare "rm -rf node_modules" --setup "rm -rf deno.lock" "deno i" "deno-this-pr i" "deno-this-pr i --unstable-lockfile-v5"
Benchmark 1: deno i
Time (mean ± σ): 464.4 ms ± 8.8 ms [User: 227.7 ms, System: 217.3 ms]
Range (min … max): 452.6 ms … 478.3 ms 10 runs
Benchmark 2: deno-this-pr i
Time (mean ± σ): 368.8 ms ± 22.0 ms [User: 150.8 ms, System: 198.1 ms]
Range (min … max): 344.8 ms … 397.6 ms 10 runs
Benchmark 3: deno-this-pr i --unstable-lockfile-v5
Time (mean ± σ): 211.9 ms ± 17.1 ms [User: 7.1 ms, System: 177.2 ms]
Range (min … max): 191.3 ms … 233.4 ms 10 runs
Summary
deno-this-pr i --unstable-lockfile-v5 ran
1.74 ± 0.17 times faster than deno-this-pr i
2.19 ± 0.18 times faster than deno i
```
With lockfile v5, a 2.19x faster install time compared to the current
deno.
- 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
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.
Allows easily constructing a `DenoResolver` using the exact same logic
that we use in the CLI (useful for dnt and for external bundlers). This
code is then used in the CLI to ensure the logic is always up-to-date.
```rs
use std::rc::Rc;
use deno_resolver:🏭:ResolverFactory;
use deno_resolver:🏭:WorkspaceFactory;
use sys_traits::impls::RealSys;
let sys = RealSys;
let cwd = sys.env_current_dir()?;
let workspace_factory = Rc::new(WorkspaceFactory::new(sys, cwd, Default::default()));
let resolver_factory = ResolverFactory::new(workspace_factory.clone(), Default::default());
let deno_resolver = resolver_factory.deno_resolver().await?;
```
This slightly degrades the performance of CJS export analysis on
subsequent runs because I changed it to no longer cache in the DENO_DIR
with this PR (denort now properly has no idea about the DENO_DIR). We'll
have to change it to embed this data in the binary and that will also
allow us to get rid of swc in denort (will do that in a follow-up PR).
split up otel config into user configurable and runtime configurable
parts. user configurable part is now set via env vars parsed according
to the otel spec. otel is now enabled via `OTEL_DENO=true`, and
`--unstable-otel` only acts as a guard.
Fixes: https://github.com/denoland/deno/issues/27273
This commit adds support for `deno init --npm <package>`.
Running this will actually call to `npm:create-<package>` package that
is equivalent to running `npm create <package>`.
User will be prompted if they want to allow all permissions and
lifecycle scripts to be executed.

This commit adds workspace support to "deno taks".
Two new flags were added:
- "--recursive" - allows to run a specified task in workspace members,
eg. "deno task --recursive dev"
- "--filter" - allows to run a specified task only in specific workspace members,
eg. "deno task --recursive --filter 'client/*' dev"
"--filter" flag implies "--recursive" flag.
Closes https://github.com/denoland/deno/issues/24991

Closes#20487
Currently spelled
```
deno outdated
```
and
```
deno outdated --update
```
Works across package.json and deno.json, and in workspaces.
There's a bit of duplicated code, I'll refactor to reduce this in follow
ups
## Currently supported:
### Printing outdated deps (current output below which basically mimics
pnpm, but requesting feedback / suggestions)
```
deno outdated
```

### Updating deps
semver compatible:
```
deno outdated --update
```
latest:
```
deno outdated --latest
```
current output is basic, again would love suggestions

#### Filters
```
deno outdated --update "@std/*"
deno outdated --update --latest "@std/* "!@std/fmt"
```
#### Update to specific versions
```
deno outdated --update @std/fmt@1.0.2 @std/cli@^1.0.3
```
### Include all workspace members
```
deno outdated --recursive
deno outdated --update --recursive
```
## Future work
- interactive update
- update deps in js/ts files
- better support for transitive deps
Known issues (to be fixed in follow ups):
- If no top level dependencies have changed, we won't update transitive
deps (even if they could be updated)
- Can't filter transitive deps, or update them to specific versions
## TODO (in this PR):
- ~~spec tests for filters~~
- ~~spec test for mixed workspace (have tested manually)~~
- tweak output
- suggestion when you try `deno update`

This commit adds `--eval` flag to `deno task` subcommand.
This flag allows to evaluate provided "task name" as a task itself,
effectively allowing to use `deno_task_shell` from the command line.
Also fixes shebang parsing for `node_modules/.bin/` entries to handle
`#!/usr/bin/node -S node` in addition to `#!/usr/bin/node node`.
Closes https://github.com/denoland/deno/issues/26918
Improving the breadth of collected data, and ensuring that the collected
data is more likely to be successfully reported.
- Use `log` crate in more places
- Hook up `log` crate to otel
- Switch to process-wide otel processors
- Handle places that use `process::exit`
Also adds a more robust testing framework, with a deterministic tracing
setting.

with Node-API addons using global cache (which is currently not
supported).
Closes https://github.com/denoland/deno/issues/25974
This commit adds better handling for terminal errors when
`window` global is used. This global is removed in Deno 2,
and while we have lints to help with that, an information and
hints are helpful to guide users to working code.
Ref https://github.com/denoland/deno/issues/25797
This commit lets `deno test --doc` command actually evaluate code snippets in
JSDoc and markdown files.
## How it works
1. Extract code snippets from JSDoc or code fences
2. Convert them into pseudo files by wrapping them in `Deno.test(...)`
3. Register the pseudo files as in-memory files
4. Run type-check and evaluation
We apply some magic at the step 2 - let's say we have the following file named
`mod.ts` as an input:
````ts
/**
* ```ts
* import { assertEquals } from "jsr:@std/assert/equals";
*
* assertEquals(add(1, 2), 3);
* ```
*/
export function add(a: number, b: number) {
return a + b;
}
````
This is virtually transformed into:
```ts
import { assertEquals } from "jsr:@std/assert/equals";
import { add } from "files:///path/to/mod.ts";
Deno.test("mod.ts$2-7.ts", async () => {
assertEquals(add(1, 2), 3);
});
```
Note that a new import statement is inserted here to make `add` function
available. In a nutshell, all items exported from `mod.ts` become available in
the generated pseudo file with this automatic import insertion.
The intention behind this design is that, from library user's standpoint, it
should be very obvious that this `add` function is what this example code is
attached to. Also, if there is an explicit import statement like
`import { add } from "./mod.ts"`, this import path `./mod.ts` is not helpful for
doc readers because they will need to import it in a different way.
The automatic import insertion has some edge cases, in particular where there is
a local variable in a snippet with the same name as one of the exported items.
This case is addressed by employing swc's scope analysis (see test cases for
more details).
## "type-checking only" mode stays around
This change will likely impact a lot of existing doc tests in the ecosystem
because some doc tests rely on the fact that they are not evaluated - some cause
side effects if executed, some throw errors at runtime although they do pass the
type check, etc. To help those tests gradually transition to the ones runnable
with the new `deno test --doc`, we will keep providing the ability to run
type-checking only via `deno check --doc`. Additionally there is a `--doc-only`
option added to the `check` subcommand too, which is useful when you want to
type-check on code snippets in markdown files, as normal `deno check` command
doesn't accept markdown.
