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.
