This commit adds initial support for `--preload` (aliased to `--import`)
flag that allows to load and execute multiple ES modules before the
entry point modules is executed.
This command is available in `deno run`, `deno test` and `deno bench`
subcommands.
Closes https://github.com/denoland/deno/issues/29776
- Each workspace directory is probed for a `tsconfig.json`.
- These and any that are included by their `references` are put into a
list ordered by priority.
- A tsconfig has lower priority than its `references`.
- An earlier listed entry in `references` has higher priority than a
later one.
- A probed tsconfig in an inner directory has higher priority than an
outer one. Their `references` would be interspersed between them.
- Each tsconfig has a filter based on its `files`, `include` and
`exclude` fields. If it doesn't have `files` or `include`, it will match
any path in its containing directory not exempted by `exclude`.
- For type-checking, each root path will be allocated compiler options
based on the first tsconfig it whose filter it matches from this list.
- Only if it doesn't match any tsconfig, it will fall back to using the
nearest `deno.json`. If it's a workspace member and the root `deno.json`
has `compilerOptions`, these will be merged using the same logic from
`extends`.
Inheritance between configs strictly occurs via `extends` in a
`tsconfig.json`, and between workspace member and root `deno.json`s'
`compilerOptions`. There is no implicit inheritance between
`tsconfig.json` and `deno.json`.
The default compiler options currently applied against tsconfigs are
Deno's normal defaults, with the exception of `lib`. The default value
for `lib` is `["deno.window", "deno.unstable", "dom"]` for files in the
scope of a tsconfig with `lib` unspecified. This behaviour is depended
on by, for example, the template project created by `create-vite ->
svelte`. I expect we'll add more such exceptions over time with other
fields.
Since `rust 1.87.0` reported `undefined symbol:
ring::pbkdf2::PBKDF2_HMAC_SHA1::*` in CI and it was difficult to debug
locally, use `rust 1.86.0` in CI tests for troubleshoot the errors

This PR use object_id to interact with repl internal, instead of global
variable (`__DENO_REPL_INTERNALS_{seconds}__`),
so we don't need to hide this in completions, etc.

implement lazy(?) mode. an unconfigured jsruntime is created if
DENO_UNSTABLE_CONTROL_SOCK is present, and later passed into deno_runtime to be
configured and used.
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
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.
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).
Currently deno eagerly caches all npm packages in the workspace's npm
resolution. So, for instance, running a file `foo.ts` that imports
`npm:chalk` will also install all dependencies listed in `package.json`
and all `npm` dependencies listed in the lockfile.
This PR refactors things to give more control over when and what npm
packages are automatically cached while building the module graph.
After this PR, by default the current behavior is unchanged _except_ for
`deno install --entrypoint`, which will only cache npm packages used by
the given entrypoint. For the other subcommands, this behavior can be
enabled with `--unstable-npm-lazy-caching`
Fixes#25782.

Ensures a dynamic import in a CJS file will consider the referrer as an import for node resolution.
Also adds fixes (adds) support for `"resolution-mode"` in TypeScript.
This will respect `"type": "commonjs"` in a package.json to determine if
`.js`/`.jsx`/`.ts`/.tsx` files are CJS or ESM. If the file is found to
be ESM it will be loaded as ESM though.
* cts support
* better cjs/cts type checking
* deno compile cjs/cts support
* More efficient detect cjs (going towards stabilization)
* Determination of whether .js, .ts, .jsx, or .tsx is cjs or esm is only
done after loading
* Support `import x = require(...);`

This replaces `--allow-net` for import permissions and makes the
security sandbox stricter by also checking permissions for statically
analyzable imports.
By default, this has a value of
`--allow-import=deno.land:443,jsr.io:443,esm.sh:443,raw.githubusercontent.com:443,gist.githubusercontent.com:443`,
but that can be overridden by providing a different set of hosts.
Additionally, when no value is provided, import permissions are inferred
from the CLI arguments so the following works because
`fresh.deno.dev:443` will be added to the list of allowed imports:
```ts
deno run -A -r https://fresh.deno.dev
```

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.

This commit fixes memory leak described in
https://github.com/denoland/deno/issues/24380.
This is done by upgrading following crates:
- deno_ast
- deno_graph
- eszip
- dprint-plugin-typescript
- deno_lint
- deno_doc
- deno_emit
Also removes permissions being passed in for node resolution. It was
completely useless because we only checked it for reading package.json
files, but Deno reading package.json files for resolution is perfectly
fine.
My guess is this is also a perf improvement because Deno is doing less
work.
1. Generally we should prefer to use the `log` crate.
2. I very often accidentally commit `eprintln`s.
When we should use `println` or `eprintln`, it's not too bad to be a bit
more verbose and ignore the lint rule.
