By default, `deno serve` will assign port 8000 (like `Deno.serve`).
Users may choose a different port using `--port`.
`deno serve /tmp/file.ts`
`server.ts`:
```ts
export default {
fetch(req) {
return new Response("hello world!\n");
},
};
```
When the response has been successfully send, we abort the
`Request.signal` property to indicate that all resources associated with
this transaction may be torn down.
Landing part of https://github.com/denoland/deno/pull/21903
This will allow us to more easily refactor `serveHttp` to live on top of
`serve` by splitting the websocket code out. There's probably a lot more
we could do here but this helps.
Embedders may have special requirements around file opening, so we add a
new `check_open` permission check that is called as part of the file
open process.
This PR enables V8 code cache for ES modules and for `require` scripts
through `op_eval_context`. Code cache artifacts are transparently stored
and fetched using sqlite db and are passed to V8. `--no-code-cache` can
be used to disable.

This commit moves logic of dispatching lifecycle events (
"load", "beforeunload", "unload") to be triggered from Rust.
Before that we were executing scripts from Rust, but now we
are storing references to functions from "99_main.js" and calling
them directly.
Prerequisite for https://github.com/denoland/deno/issues/23342
I'm unsure whether we're planning to make the `Deno.FsFile` constructor
illegal or remove `FsFile` from the `Deno.*` namspace in Deno 2. Either
way, this PR works towards the former. I'll create a superceding PR if
the latter is planned instead.
Towards #23089
The permission prompt doesn't wait for quiescent input, so someone
pasting a large text file into the console may end up losing the prompt.
We enforce a minimum human delay and wait for a 100ms quiescent period
before we write and accept prompt input to avoid this problem.
This does require adding a human delay in all prompt tests, but that's
pretty straightforward. I rewrote the locked stdout/stderr test while I
was in here.
This change removes deprecated methods from the `Deno.*` namespace when
the `DENO_FUTURE=1` environment variable is used.
Note: this does not address deprecated class properties and methods.
E.g. `Deno.Conn.rid`.
Slightly different approach to similar changes in #22386
Note that this doesn't use a warmup script -- we are actually just doing
more work at snapshot time.
This commit fixes passing `MessagePort` instances to
`WorkerOptions.workerData`.
Before they were not serialized and deserialized properly when spawning
a worker thread.
Closes https://github.com/denoland/deno/issues/22935
Skips the access check if the specific unary permission is in an
all-granted state. Generally prevents an allocation or two.
Hooks up a quiet "all" permission that is automatically inherited. This
permission will be used in the future to indicate that the user wishes
to accept all side-effects of the permissions they explicitly granted.
The "all" permission is an "ambient flag"-style permission that states
whether "allow-all" was passed on the command-line.
Issue https://github.com/denoland/deno/issues/22222
This PR moves `runtime/permissions` code to a upstream crate called
`deno_permissions`. The `deno_permissions::PermissionsContainer` is put
into the OpState and can be used instead of the current trait-based
permissions system.
For this PR, I've migrated `deno_fetch` to the new crate but kept the
rest of the trait-based system as a wrapper of `deno_permissions` crate.
Doing the migration all at once is error prone and hard to review.

Fixes #22724. Fixes #7164.
This does add a dependency on `signal-hook`, but it's just a higher
level API on top of `signal-hook-registry` (which we and `tokio` already
depend on) and doesn't add any transitive deps.
This commit changes how we figure out if we're running on main
thread in `node:worker_threads` module. Instead of relying on quirky
"magic variable" for a name to check if we're on main thread, we are
now explicitly passing this information during bootstrapping of the
runtime. As a side effect, `WorkerOptions.name` is more useful
and matches what Node.js does more closely (though not fully).

This commit adds support for source maps for `ext/` crates that are
authored in TypeScript. As a result any exceptions thrown from eg. `ext/node`
will now have correct stack traces.
This is only enabled in debug mode as it adds about 2Mb to the binary.
Improves #19100
Fixes #20356
Replaces #20428
Changes made in deno_core to support this:
- [x] Errors must be handled in setTimeout callbacks
- [x] Microtask ordering is not-quite-right
- [x] Timer cancellation must be checked right before dispatch
- [x] Timer sanitizer
- [x] Move high-res timer to deno_core
- [x] Timers need opcall tracing
- Removes the origin call, since all origins are the same for an isolate
(ie: the main module)
- Collects the `TestDescription`s and sends them all at the same time
inside of an Arc, allowing us to (later on) re-use these instead of
cloning.
Needs a follow-up pass to remove all the cloning, but that's a thread
that is pretty long to pull

If we strip out unprintable chars, we don't see the full filename being
requested by permission prompts. Instead, we highlight and escape them
to make them visible.
This commit removes some not really necessary FFI tests and in effect
removes them from being accessible from the user code.
This lowers the number of ops accessible to user code to 16.
This moves the op sanitizer descriptions into Rust code and prepares for
eventual op import from `ext:core/ops`. We cannot import these ops from
`ext:core/ops` as the testing infrastructure ops are not always present.
Changes:
- Op descriptions live in `cli` code and are currently accessible via an
op for the older sanitizer code
- `phf` dep moved to workspace root so we can use it here
- `ops.op_XXX` changed to to `op_XXX` to prepare for op imports later
on.
Migrations:
- Error registration no longer required for Interrupted or BadResource
(these are core exception)
- `include_js_files!`/`ExtensionFileSource` changes
This commit adds a list of ops to `runtime/99_main.js` that are
currently relying on getting them from `Deno.core.ops`. All ops that are not
present in the list are removed from `Deno.core.ops` on startup (they are
imported from "virtual op module" - `ext:core/ops`) making them effectively
inaccessible to user code.
This change lowers the number of ops exposed to user code from 650 to
around 260. This number should be gradually decreased in follow-up PRs.
Follow up to #22157.
This leaves us with 4 usages of `ensureFastOps()` in `deno` itself.
There's also about 150 usages of `Deno.core.ops.<op_name>` left as well.
For removal in Deno v2. I've also updated the deprecation of
`Deno.FsWatcher.return()`, which, to be clear, I'm not in favour of
deprecating. I mention this in #15499. Either way, it's safe to merge
this PR, then decide against the deprecation.
Removes weird "frame like" characters and simplifies the output:
```
warning: Use of deprecated "Deno.isatty()" API. This API will be removed in Deno 2.

This commit deprecates `window` global and adds deprecation
notice on each use of `window`.
We decided to proceed with removal of `window` global variable in Deno
2.0. There's a lot of code
in the wild that uses pattern like this:
```
if (typeof window !== "undefined) {
...
}
```
to check if the code is being run in browser. However, this check passes
fine in Deno and
most often libraries that do this check try to access some browser API
that is not available
in Deno, or use DOM APIs (which are also not available in Deno).
This situation has occurred multiple times already
and it's unfeasible to expect the whole ecosystem to migrate to new
check (and even if that
happened there's a ton of code that's already shipped and won't change).
The migration is straightfoward - replace all usages of `window` with
`globalThis` or `self`.
When Deno encounters use of `window` global it will now issue a warning,
steering users
towards required changes:
```
Warning
├ Use of deprecated "window" API.
│
├ This API will be removed in Deno 2.0. Make sure to upgrade to a stable API before then.
│
├ Suggestion: Use `globalThis` or `self` instead.
│
├ Suggestion: You can provide `window` in the current scope with: `const window = globalThis`.
│
└ Stack trace:
└─ at file:///Users/ib/dev/deno/foo.js:7:1
```
Ref https://github.com/denoland/deno/issues/13367.
Most uses of `Deno.resources()` within tests, as they previously checked
for leaked resources. This is not needed as the test runner does this
automatically. Other internal uses of this API have been replaced with
the internal `Deno[Deno.internal].core.resources()`.
This change:
1. Implements `Deno.stdin.isTerminal()`, `Deno.stdout.isTerminal()` and
`Deno.stderr.isTerminal()`.
2. Deprecates `Deno.isatty()` for removal in Deno v2, in favour of the
above instance methods.
3. Replaces use of `Deno.isatty()` with the above instance methods.

This change:
1. Sets the removal version for `Deno.RequestEvent`, `Deno.HttpConn` and
`Deno.serveHttp()` for Deno v2. I thought it might be worth calling
`warnOnDeprecatedApi()` within `Deno.Request` and `Deno.HttpConn`
methods, but I thought just having it called within `Deno.serveHttp()`
might be sufficient.
2. Removes some possibly unneeded related benchmarks.
Towards #22021
Closes https://github.com/denoland/deno/issues/21828.
This API is a huge footgun. And given that "Deno.serveHttp" is a
deprecated API that is discouraged to use (use "Deno.serve()"
instead); it makes no sense to keep this API around.
This is a step towards fully migrating to Hyper 1.
Fixes #21928.
We have a code path which empties the extension sources because they're
expected to be pre-executed in the snapshot. Instead of using
conditional compilation for that, we now just check if a snapshot was
provided.
Removes the `dont_use_runtime_snapshot` feature. We didn't allow not
providing a snapshot unless this feature was provided, now we always do.
Adds the `only_snapshotted_js_sources` feature for us to use in CLI.
This asserts that a snapshot is provided and gates the runtime
transpilation code so it isn't included in the executable.
This commit introduces deprecation warnings for "Deno.*" APIs.
This is gonna be quite noisy, but should tremendously help with user
code updates to ensure
smooth migration to Deno 2.0. The warning is printed at each unique call
site to help quickly
identify where code needs to be adjusted. There's some stack frame
filtering going on to
remove frames that are not useful to the user and would only cause
confusion.
The warning can be silenced using "--quiet" flag or
"DENO_NO_DEPRECATION_WARNINGS" env var.
"Deno.run()" API is now using this warning. Other deprecated APIs will
start warning
in follow up PRs.
Example:
```js
import { runEcho as runEcho2 } from "http://localhost:4545/run/warn_on_deprecated_api/mod.ts";
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
async function runEcho() {
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
}
await runEcho();
await runEcho();
for (let i = 0; i < 10; i++) {
await runEcho();
}
await runEcho2();

Part 1 of #21713
Changes:
- Remove `.present()` and add a `presentGPUCanvasContext` (not exposed
yet to users)
- Move lazy load logic to `00_init.js`. This can be used to use webgpu
on-demand from future code (OffScreenCanvas)
Harden the code that does permission checks to protect against
re-opening of stdin.
Code that runs FFI is vulnerable to an attack where fd 0 is closed
during a permission check and re-opened with a file that contains a
positive response (ie: `y` or `A`). While FFI code is dangerous in
general, we can make it more difficult for FFI-enabled code to bypass
additional permission checks.
- Checks to see if the underlying file for stdin has changed from the
start to the end of the permission check (detects races)
- Checks to see if the message is excessively long (lowering the window
for races)
- Checks to see if stdin and stderr are still terminals at the end of
the function (making races more difficult)
Main change is that:
- "hyper" has been renamed to "hyper_v014" to signal that it's legacy
- "hyper1" has been renamed to "hyper" and should be the default
`opAsync` requires a lookup by name on each async call. This is a
mechanical translation of all opAsync calls to ensureFastOps.
The `opAsync` API on Deno.core will be removed at a later time.
This PR implements the child_process IPC pipe between parent and child.
The implementation uses Windows named pipes created by parent and passes
the inheritable file handle to the child.
I've also replace parts of the initial implementation which passed the
raw parent fd to JS with resource ids instead. This way no file handle
is exposed to the JS land (both parent and child).

This PR implements the Node child_process IPC functionality in Deno on
Unix systems.
For `fd > 2` a duplex unix pipe is set up between the parent and child
processes. Currently implements data passing via the channel in the JSON
serialization format.
This fixes #21434 for `BroadcastChannel` and `WebSocketStream`.
`--unstable` still enable both, but granular unstable flags now also
work:
* `--unstable-net` now enables `WebSocketStream`.
* `--unstable-broadcast-channel` now enables `BroadcastChannel`.
* Additionally, there are now tests for all granular unstable flags.
Since `unsafe-proto` already had tests, so I didn't add any for this
one.
It also introduces a map to keep track of granular unstable ids without
having to sync multiple places.
This commit brings back usage of primordials in "40_testing.js" by

This commit refactors how we access "core", "internals" and
"primordials" objects coming from `deno_core`, in our internal JavaScript code.
Instead of capturing them from "globalThis.__bootstrap" namespace, we
import them from recently added "ext:core/mod.js" file.
Landing changes required for

We needed to update 99_main.js and a whole load of tests.
API changes:
- setPromiseRejectCallback becomes setUnhandledPromiseRejectionHandler.
The function is now called from eventLoopTick.
- The promiseRejectMacrotaskCallback no longer exists, as this is
automatically handled in eventLoopTick.
- ops.op_dispatch_exception now takes a second parameter: in_promise.
The preferred way to call this op is now reportUnhandledException or
reportUnhandledPromiseRejection.
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

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])`
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.

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 commit updates the ext/kv module to use the denokv_* crates for
the protocol and the sqlite backend. This also fixes a couple of bugs in
the sqlite backend, and updates versionstamps to be updated less
linearly.
