This commits adds the ability to set a would-be exit code
for the Deno process without forcing an immediate exit,
through the new `Deno.exitCode` API.
- **Implements `Deno.exitCode` getter and setter**: Adds support for
setting
and retrieving a would-be exit code via `Deno.exitCode`.
This allows for asynchronous cleanup before process termination
without immediately exiting.
- **Ensures type safety**: The setter for `Deno.exitCode` validates that
the provided value is a number, throwing a TypeError if not, to ensure
that
only valid exit codes are set.
Closes to #23605

In https://github.com/denoland/deno/pull/23955 we changed the sqlite db
journal mode to WAL. This causes issues when someone is running an old
version of Deno using TRUNCATE and a new version because the two fight
against each other.
The mixed `number | bigint` representation was useful optimization for
pointers. Now, pointers are represented as V8 externals. As part of the
FFI stabilization effort we want to make `bigint` the only
representation for `u64` and `i64`.
BigInt representation performance is almost on par with mixed
representation with the added benefit that its less confusing and users
don't need manual checks and conversions for doing operations on the
value.

Fixes #23643.
We weren't catching the cancellation exception thrown by TSC on the JS
side, so the rust side was catching this exception and then attempting
to print out the exception via `toString`. That last bit resulted in a
cryptic `[object Object]` showing up in the logs like so:
```
Error during TS request "getCompletionEntryDetails":
[object Object]
```
I'm not 100% sure how we weren't seeing this in the past. My guess is
that #23409 and the subsequent PR to improve the exception catching and
logging surfaced this, but I'm still not quite clear on it.
My initial fix here returned `null` to rust when a server request was
cancelled, but this resulted in a deserialization error when we
attempted to deserialize that into the expected response type. So now,
as soon as the request's cancellation token signals we'll stop waiting
for a response and return an error (which will get swallowed as the LSP
request is being cancelled).
I was a bit surprised to find that [this
branch](0c671c9792/cli/lsp/tsc.rs (L1093))
actually executes sometimes, I believe due to the fact that aborting a
future may not [immediately stop its
execution](https://docs.rs/futures/latest/futures/stream/struct.AbortHandle.html#method.abort).
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.

This PR wires up a new `jsxPrecompileSkipElements` option in
`compilerOptions` that can be used to exempt a list of elements from
being precompiled with the `precompile` JSX transform.
The actual handling of `$projectChanged` is quick, but JS requests are
not. The cleared caches only get repopulated on the next actual request,
so just batch the change notification in with the next actual request.
No significant difference in benchmarks on my machine, but this speeds
up `did_change` handling and reduces our total number of JS requests (in
addition to coalescing multiple JS change notifs into one).
Adds an `addr` field to `HttpServer` to simplify the pattern
`Deno.serve({ onListen({ port } => listenPort = port })`. This becomes:
`const server = Deno.serve({}); port = server.addr.port`.
Changes:
- Refactors `serve` overloads to split TLS out (in preparation for
landing a place for the TLS SNI information)
- Adds an `addr` field to `HttpServer` that matches the `addr` field of
the corresponding `Deno.Listener`s.
This allows people to use imports like:
```ts
import "./app.css";
```
...with `deno check` in systems where there's a bundle step (ex. Vite).
This will still error when using it with `deno run` or if the referenced
file does not exist.
See test cases for behaviour.
I'm running into a node resolution bug in the lsp only and while
tracking it down I noticed this one.
Fixed by moving the project version out of `Documents`.
…faces (#23296)"
This reverts commit e190acbfa8.
Reverting because it broke stable API type declarations. We will reland
it for v1.43 with updated interfaces
Currently we evict a lot of the caches on the JS side of things on every
request, namely script versions, script file names, and compiler
settings (as of #23283, it's not quite every request but it's still
unnecessarily often).
This PR reports changes to the JS side, so that it can evict exactly the
caches that it needs too. We might want to do some batching in the
future so as not to do 1 request per change.
Removes the certificate options from all the interfaces and replaces
them with a new `TlsCertifiedKeyOptions`. This allows us to centralize
the documentation for TLS key management for both client and server, and
will allow us to add key object support in the future.
Also adds an option `keyFormat` field to the cert/key that must be
omitted or set to `pem`. This will allow us to load other format keys in
the future `der`, `pfx`, etc.
In a future PR, we will add a way to load a certified key object, and we
will add another option to `TlsCertifiedKeyOptions` like so:
```ts
export interface TlsCertifiedKeyOptions =
| TlsCertifiedKeyPem
| TlsCertifiedKeyFromFile
| TlsCertifiedKeyConnectTls
| { key: Deno.CertifiedKey }
```
Changes `discreet` in the documentation for `discrete`
"Discreet" means careful to avoid being noticed, "discrete" means
separate parts, and is what the documentation refers to.
The TS language service requests source files via
[getSourceFile](7a25fd5ef0/cli/tsc/99_main_compiler.js (L560)).
In that function, we [unconditionally
add](7a25fd5ef0/cli/tsc/99_main_compiler.js (L613-L614))
the source file to our sourceFileCache. The issue is that we only remove
things from that cache if the source file [becomes out of
date](7a25fd5ef0/cli/tsc/99_main_compiler.js (L777-L783)).
For files that don't get changed, we keep them in the cache
indefinitely. So sometimes we keep SourceFile objects from being GC'ed
because they're retained in our cache, even though TS doesn't refer to
them any more. I see this in pretty much all of the heap snapshots I've
taken.
---
The fix here is pretty direct - just store weak references to the
sourcefiles in the cache. It doesn't really change our caching behavior,
it just prevents us from being the only retainer of a `SourceFile`. I
also split the `sourceFileCache` into a separate cache just for assets,
as we rely on those being alive.
The simpler fix is to only cache assets, but presumably that has a perf
impact.
---
In local testing, this PR reduced the size of the JS heap by about 1 GB
when using `deno lsp` in the Typescript repo.
Unused locals and parameters don't make sense to surface in remote
modules. Additionally, fast check can cause these kind of diagnostics
when publishing, so they should be ignored.
Closes #22959
This has been incorrect since the function adopted its (more intuitive)
current behavior in 9268df5f3. The same behavior change was backported
to v1.39.3 in 87e954f54.
This change deprecates
`Deno.CreateHttpClientOptions.{certChain,privateKey}` in favour of
`Deno.CreateHttpClientOptions.{cert,key}`.
Closes #22278

This changes the lockfile to not store JSR specifiers in the "remote"
section. Instead a single JSR integrity is stored per package in the
lockfile, which is a hash of the version's `x.x.x_meta.json` file, which
contains hashes for every file in the package. The hashes in this file
are then compared against when loading.
Additionally, when using `{ "vendor": true }` in a deno.json, the files
can be modified without causing lockfile errors—the checksum is only
checked when copying into the vendor folder and not afterwards
(eventually we should add this behaviour for non-jsr specifiers as
well). As part of this change, the `vendor` folder creation is not
always automatic in the LSP and running an explicit cache command is
necessary. The code required to track checksums in the LSP would have
been too complex for this PR, so that all goes through deno_graph now.
The vendoring is still automatic when running from the CLI.
For removal in Deno v2. There are two issues:
1. Any script being run causes the output of `warnOnDeprecatedApi()` to
be printed, even when none of the `rid` properties are called.
2. `.rid` of these classes is used in multiple tests. I'm not sure how
to account for that. I thought of having `STDIN_RID`, and friends,
constants, whose values can be shared between the tests and the classes
themselves. Should we go with that or do something else?

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.
- changed `Deno.UnsafeWindowSurface` typings from accepting
`Deno.UnsafePointerView` to `Deno.PointerValue`

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

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.

This commit adds `import.meta.filename` and `import.meta.dirname` APIs.
These APIs return string representation of filename and containing
dirname.
They are only defined for local modules (modules that have `file:///`
scheme).
Example:
```ts
console.log(import.meta.filename, import.meta.dirname)
```
Unix:
```
$ deno run /dev/my_module.ts
/dev/my_module.ts /dev/
```
Windows:
```
$ deno run C:\dev\my_module.ts
C:\dev\my_module.ts C:\
```

This change removes the currently deprecated `Deno.cron()` overload with
`options` as a potential last argument.
This might be fine to do now, in a major release, as `Deno.cron()` is an
unstable API. I thought of doing this while working on #22021. If this
is not ready to remove, I can instead set the removal version of this
overload for Deno v2.
Note: this overload was deprecated in Deno v1.38.2 (#21225). So it's
been deprecated for over 2 months.
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.
This change takes advantage of explicit resources management for
`FsFile` instances and tweaks documentation to encourage the use of it.

This commit removes conditional type-checking of unstable APIs.
Before this commit `deno check` (or any other type-checking command and
the LSP) would error out if there was an unstable API in the code, but not
`--unstable` flag provided.
This situation hinders DX and makes it harder to configure Deno. Failing
during runtime unless `--unstable` flag is provided is enough in this case.
This commit adds support for "rejectionhandled" Web Event and
"rejectionHandled" Node event.
```js
import process from "node:process";
process.on("rejectionHandled", (promise) => {
console.log("rejectionHandled", reason, promise);
});
window.addEventListener("rejectionhandled", (event) => {
console.log("rejectionhandled", event.reason, event.promise);

This defines the removal version of v2 for the following APIs that
favour the Streams API:
* `Deno.copy()`
* `Deno.File`
* `Deno.iter()`
* `Deno.Buffer`
* `Deno.readAll()`
* `Deno.readAllSync()`
* `Deno.writeAll()`
* `Deno.writeAllSync()`
* `Deno.FsWatcher.return()`
This change deprecates `Deno.Reader`, `Deno.ReaderSync`, `Deno.Writer`,
`Deno.WriterSync` and `Deno.Closer` in favour of the [Web Streams
API](https://developer.mozilla.org/en-US/docs/Web/API/Streams_API).
After discussing with Yoshiya, we both thought now might be the right
time to deprecate these interfaces with v2 getting closer.
This commit stabilizes "Deno.HttpServer.shutdown" API as well as

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.
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.
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
