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
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
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.
This extracts out the shared libraries and `.node` native modules to a
temp file and opens them from there. **This means that this
implementation will not work in every scenario.** For example, a library
could require other files that only exist in the in-memory file system.
To solve that, we'll introduce
https://github.com/denoland/deno/issues/28918 later or adapt this
solution to solve more issues.
Additionally, this will not work when run on readonly file systems.
Updates to use rust 1.85. Doesn't move to the 2024 edition, as that's a
fair bit more involved.
A nice side benefit is that the new rustc version seems to lead to a
slight reduction in binary size (at least on mac):

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.
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).
This PR extracts the core part of
https://github.com/denoland/deno/pull/27203 to make it easier to review
and land in parts.
It contains:
- The JS plugin code the deserializes and walks the buffer
- The Rust portion to serialize SWC to the buffer format (a bunch of
nodes are still todos, but imo these can land anytime later)
- Basic lint plugin types, without the AST node types to make this PR
easier to review
- Added more code comments to explain the format etc.
More fixes and changes will be done in follow-up PRs.

This change fixes the premature exit of worker threads when there are still
remaining pending ops.
This change reuses the idea of #22647 (unref'ing `op_worker_recv_message` in
worker threads if closeOnIdle specified) and uses
`web_worker.has_message_event_listener` check in the opposite way as
#22944. (Now we continue the worker when `has_message_event_listener` is
true instead of stopping it when `has_message_event_listener` is false.
closes#23061closes#26154
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
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 commit improves permission prompts by adding an option
to print a full trace of where the permissions is being requested.
Due to big performance hint of stack trace collection, this is only
enabled when `DENO_TRACE_PERMISSIONS` env var is present.
Closes https://github.com/denoland/deno/issues/20756

Adds a lazily created code cache to `deno compile` by default.
The code cache is created on first run to a single file in the temp
directory and is only written once. After it's been written, the code
cache becomes read only on subsequent runs. Only the modules loaded
during startup are cached (dynamic imports are not code cached).
The code cache can be disabled by compiling with `--no-code-cache`.
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.
Initial import of OTEL code supporting tracing. Metrics soon to come.
Implements APIs for https://jsr.io/@deno/otel so that code using
OpenTelemetry.js just works tm.
There is still a lot of work to do with configuration and adding
built-in tracing to core APIs, which will come in followup PRs.

* 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(...);`

When using the `--unstable-detect-cjs` flag or adding `"unstable":
["detect-cjs"]` to a deno.json, it will make a JS file CJS if the
closest package.json contains `"type": "commonjs"` and the file is not
an ESM module (no TLA, no `import.meta`, no `import`/`export`).
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
```
