This commit removes some of the technical debt related
to snapshotting JS code:
- "cli/ops/mod.rs" and "cli/build.rs" no longer define "cli" extension
which was not required anymore
- Cargo features for "deno_runtime" crate have been unified in
"cli/Cargo.toml"
- "cli/build.rs" uses "deno_runtime::snapshot::create_runtime_snapshot"
API
instead of copy-pasting the code
- "cli/js/99_main.js" was completely removed as it's not necessary
anymore

This PR causes Deno to include more files in the graph based on how a
template literal looks that's provided to a dynamic import:
```ts
const file = await import(`./dir/${expr}`);
```
In this case, it will search the `dir` directory and descendant
directories for any .js/jsx/etc modules and include them in the graph.
To opt out of this behaviour, move the template literal to a separate
line:
```ts
const specifier = `./dir/${expr}`
const file = await import(specifier);
```
Switch `ext/fetch` over to `resourceForReadableStream` to simplify and
unify implementation with `ext/serve`. This allows us to work in Rust
with resources only.
Two additional changes made to `resourceForReadableStream` were
required:
- Add an optional length to `resourceForReadableStream` which translates
to `size_hint`
- Fix a bug where writing to a closed stream that was full would panic
This commit changes LSP log names by prefixing them, we now have these
prefixes:
- `lsp.*` - requests coming from the client
- `tsc.request.*` - requests coming from clients that are routed to TSC
- `tsc.op.*` - ops called by the TS host
- `tsc.host.*` - requests that call JavaScript runtime that runs
TypeScript compiler host
Additionall `Performance::mark` was split into `Performance::mark` and
`Performance::mark_with_args` to reduce verbosity of code and logs.
This commit removes "ThrottledCancellationToken" in favor of
"CancellationToken".
Since calling into Rust to check if Tokio's cancellation token has
already been canceled is really cheap, there's no need for us to
throttle this check and let TSC burn up CPU with heavy computation.
When an old request is obsoleted while the user is typing, the client
will say so to the server and tower-lsp will drop the future associated
with that request.
This wires that up to the ts server by having any request's token be
cancelled when the surrounding state is dropped.
The self-upgrade feature is undesirable when deno is installed from
(Linux) distribution repository - using a system package manager. This
change will allow package maintainers to build deno with the "upgrade"
subcommand and background check disabled.
When the user runs `deno upgrade <args>` and the upgrade feature is
disabled, it will exit with error message explaining that this deno
binary was built without the upgrade feature.
Note: This patch is already used in the Alpine Linux’s
[deno](https://pkgs.alpinelinux.org/packages?name=deno) package.
What `Deno.ChildProcess` actually implements is `AsyncDisposable`, but the type
declaration says it's `Disposable`. This PR fixes the type declaration to match
the actual implementation.
Issue was main does canary builds, which broke this test because it
didn't handle searching for a canary release. Tested by building as
canary locally.
This PR updates the deprecation notices to point to the same replacement
APIs that the Standard Library points to. I've also tweaked the notices
to be a little more presentable/navigatable.
In particular, a follow-up PR in std will be made that documents the use
of `toArrayBuffer()`.
Closes #21193
Towards #20976
This commit adds unstable workspace support. This is extremely
bare-bones and
minimal first-pass at this.
With this change `deno.json` supports specifying `workspaces` key, that
accepts a list of subdirectories. Each workspace can have its own import
map. It's required to specify a `"name"` and `"version"` properties in the
configuration file for the workspace:
```jsonc
// deno.json
{
"workspaces": [
"a",
"b"
},
"imports": {
"express": "npm:express@5"
}
}
```
``` jsonc
// a/deno.json
{
"name": "a",
"version": "1.0.2",
"imports": {
"kleur": "npm:kleur"
}
}
```
```jsonc
// b/deno.json
{
"name": "b",
"version": "0.51.0",
"imports": {
"chalk": "npm:chalk"
}
}
```
`--unstable-workspaces` flag is required to use this feature:
```
$ deno run --unstable-workspaces mod.ts
```

This PR changes the `Deno.cron` API:
* Marks the existing function as deprecated
* Introduces 2 new overloads, where the handler arg is always last:
```ts
Deno.cron(
name: string,
schedule: string,
handler: () => Promise<void> | void,
)
Deno.cron(
name: string,
schedule: string,
options?: { backoffSchedule?: number[]; signal?: AbortSignal },
handler: () => Promise<void> | void,
)
```
This PR also fixes a bug, when other crons continue execution after one
of the crons was closed using `signal`.
Fixes #21121 and #19498
Migrates fully to rustls_tokio_stream. We no longer need to maintain our
own TlsStream implementation to properly support duplex.
This should fix a number of errors with TLS and websockets, HTTP and
"other" places where it's failing.
This PR uses the new `cancel` method of `TransformStream` to properly
clean up the internal `TextDecoder` used in `TextDecoderStream` if the
stream is cancelled.
Fixes #13142

We only want one zlib dependency.
Zlib dependencies are reorganized so they use a hidden
`__vendored_zlib_ng` flag in cli that enables zlib-ng for both libz-sys
(used by ext/node) and flate2 (used by deno_web).
This also updates deno_graph, which has the JSR change to use "exports".
It's not yet useful atm, so I've made this PR a fix about the deno doc
--lint error message improvements. I'll do a follow-up PR that adds
exports to the deno.json
This is the release commit being forwarded back to main for 1.38.1

This PR reduces the time to run `queue persistence with inflight
messages` test from 60 seconds down to about 6 seconds.
The test simulates a crash to ensure that inflight messages are cleaned
up and re-queued when the new process starts. Since messages are
considered dead after 5 seconds of being queued, reopening the db within
5 seconds does not re-queue the messages on startup (they do get
re-queued after 60 seconds, which is the cleanup frequency). By waiting
for 5 seconds before reopening the db, the test ensures that the cleanup
happens quickly when the db is opened.
We can move all promise ID knowledge to deno_core, allowing us to better
experiment with promise implementation in deno_core.
`{un,}refOpPromise(promise)` is equivalent to
`{un,}refOp(promise[promiseIdSymbol])`
Remove tokio-rustls as a direct dependency of Deno and refactor
test_server to reduce code duplication.
All tcp and tls listener paths go through the same streams now, with the
exception of the simpler Hyper http-only handlers (those can be done in
a later follow-up).
Minor bugs fixed:
- gRPC server should only serve h2
- WebSocket over http/2 had a port overlap
- Restored missing eye-catchers for some servers (still missing on Hyper
ones)
This commit moves all Chrome Devtools Protocol messages to `cli/cdp.rs`
and refactors all places using these types to pull them from a common
place.
No functional changes.
As pointed out in https://github.com/denoland/deno/issues/21067 , it's
confusing that `deno doc --lint mod.ts` outputs the documentation to
stdout on success. Instead, it would be better if it outputted how many
files were checked similar to what `deno lint` does on success. It still
outputs the documentation if `--lint` or `--html` are provided so this
is non-breaking.
This commit adds granular `--unstable-*` flags:
- "--unstable-broadcast-channel"
- "--unstable-ffi"
- "--unstable-fs"
- "--unstable-http"
- "--unstable-kv"
- "--unstable-net"
- "--unstable-worker-options"
- "--unstable-cron"
These flags are meant to replace a "catch-all" flag - "--unstable", that
gives a binary control whether unstable features are enabled or not. The
downside of this flag that allowing eg. Deno KV API also enables the FFI
API (though the latter is still gated with a permission).
These flags can also be specified in `deno.json` file under `unstable`
key.
Currently, "--unstable" flag works the same way - I will open a follow
up PR that will print a warning when using "--unstable" and suggest to use
concrete "--unstable-*" flag instead. We plan to phase out "--unstable"
completely in Deno 2.
Implements `WebSocket` over http/2. This requires a conformant http/2
server supporting the extended connect protocol.
Passes approximately 100 new WPT tests (mostly `?wpt_flags=h2` versions
of existing websockets APIs).
This is implemented as a fallback when http/1.1 fails, so a server that
supports both h1 and h2 WebSockets will still end up on the http/1.1
upgrade path.
The patch also cleas up the websockets handshake to split it up into
http, https+http1 and https+http2, making it a little less intertwined.
This uncovered a likely bug in the WPT test server:

This PR adds unstable `Deno.cron` API to trigger execution of cron jobs.
* State: All cron state is in memory. Cron jobs are scheduled according
to the cron schedule expression and the current time. No state is
persisted to disk.
* Time zone: Cron expressions specify time in UTC.
* Overlapping executions: not permitted. If the next scheduled execution
time occurs while the same cron job is still executing, the scheduled
execution is skipped.
* Retries: failed jobs are automatically retried until they succeed or
until retry threshold is reached. Retry policy can be optionally
specified using `options.backoffSchedule`.
This change adds the `--env=[FILE]` flag to the `run`, `compile`,
`eval`, `install` and `repl` subcommands. Environment variables set in
the CLI overwrite those defined in the `.env` file.
