This fixes #20767.
We were losing `this` and then when an exception was happening, it
didn't show up in the output because we weren't bubbling up exceptions
from within a user defined function for displaying. I thought about
doing a `.call(object)` but didn't want to get in the way of a bound
`this` that a user or library was already putting on the function.
Adds `buffers` to the `Deno.jupyter.broadcast` API to send binary data
via comms. This affords the ability to send binary data via websockets
to the jupyter widget frontend.
fixes #20454
Current KV queues implementation assumes that `enqueue` and
`listenQueue` are called on the same instance of `Deno.Kv`. It's
possible that the same Deno process opens multiple KV instances pointing
to the same fs path, and in that case `listenQueue` should still get
notified of messages enqueued through a different KV instance.
This makes `CliNpmResolver` a trait. The terminology used is:
- **managed** - Deno manages the node_modules folder and does an
auto-install (ex. `ManagedCliNpmResolver`)
- **byonm** - "Bring your own node_modules" (ex. `ByonmCliNpmResolver`,
which is in this PR, but unimplemented at the moment)
Part of #18967
This API is providing hoops to jump through with undergoing migration to
`#[op2]` macro.
The overhead of supporting this API is non-trivial and besides internal
use of it in test sanitizers is very rarely used in the wild.
This helps reduce flakes where a test starts an HTTP server and makes a
request using fetch, then shuts down the server, then starting a new
test with a new server, but the connection pool still has a "not quite
closed yet" connection to the old server, and a new request to the new
server gets sent on the closed connection, which obviously errors out.
Previously could flake on the op sanitizer because the
`await makeTempFile()` promise could leak out of the test. Now we ensure
the request is fully handled before returning.
We can go one level down in abstraction and avoid using the public
`ReadableStream` APIs.
This patch ~5% perf boost on small ReadableStream:

When sending configuration requests to the client, reads `javascript`
and `typescript` sections in addition to `deno`.
The LSP's initialization options now accepts `javascript` and
`typescript` namespaces.
Give auto-import completion entries a sort-text suffix depending on if
the specifier parses as a URL. This will favour relative and bare
(likely import-mapped) specifiers.
Adds an experimental unstable built-in package manager to Deno, but it is
currently not usable because the registry infrastructure hasn't been
setup and it points to a non-existent url by default. The default
registry url can be configured via the `DENO_REGISTRY_URL` environment
variable.

# Implementation
Instead of going the route of recursively getting all the objects under
`application/.*json` keys, I went with `JSON.stringify`ing in denospace
then parsing it from rust. One of the key benefits of serializing and
deserializing is that non-JSON-able entries will get stripped
automatically. This also keeps the code pretty simple.
In the future we should _only_ do this for `application/.*json` keys.

"Fixes" the exception display issue of #20524 on older versions of
Jupyter that required `evalue` to be truthy. For now, until we can do
proper processing of the `ExceptionDetails` this will make Jupyter
Notebook 6.5.1 and below happy.
This is the alternative "just work now" PR to #20530
This commit improves async op sanitizer speed by only delaying metrics
collection if there are pending ops. This
results in a speedup of around 30% for small CPU bound unit tests.
It performs this check and possible delay on every collection now,
fixing an issue with parent test leaks into steps.
This commit adds "deno jupyter" subcommand which
provides a Deno kernel for Jupyter notebooks.
The implementation is mostly based on Deno's REPL and
reuses large parts of it (though there's some clean up that
needs to happen in follow up PRs). Not all functionality of
Jupyter kernel is implemented and some message type
are still not implemented (eg. "inspect_request") but
the kernel is fully working and provides all the capatibilities
that the Deno REPL has; including TypeScript transpilation
and npm packages support.

This adds the ability to pattern match unordered lines. For example, the
downloading messages may appear in any order
```
[UNORDERED_START]
Download https://localhost:4546/a.ts
Download https://localhost:4546/b.ts
[UNORDERED_END]
Hello!
```
Additionally, I've made the pattern matching slightly more strict and the output better.
TaskQueue is being removed from `deno_core` and replaced with an unsync
version in deno_unsyc.
https://github.com/denoland/deno_core/pull/193
This is a change in preparation for that. The remaining
`deno_core::TaskQueue` usage in this repo should be replaced with
`deno_core::unsync::TaskQueue` once upgraded.
### What
Skip writing files from the template if the files already exist in the
project directory.
### Why
When I run deno init in a directory that already has a main.ts, or one
of the other template files, I usually want to initialize a workspace
around a file I've started working in. A hard error in this case seems
counter productive. An informational message about what's being skipped
seems sufficient.
Close #20433
Removes usage of `serde_json::Value` in several ops used in TSC, in
favor of using strongly typed structs. This will unblock more
changes in https://github.com/denoland/deno/pull/20462.
This PR implements a graceful shutdown API for Deno.serve, allowing all
current connections to drain from the server before shutting down, while
preventing new connections from being started or new transactions on
existing connections from being created.
We split the cancellation handle into two parts: a listener handle, and
a connection handle. A graceful shutdown cancels the listener only,
while allowing the connections to drain. The connection handle aborts
all futures. If the listener handle is cancelled, we put the connections
into graceful shutdown mode, which disables keep-alive on http/1.1 and
uses http/2 mechanisms for http/2 connections.
In addition, we now guarantee that all connections are complete or
cancelled, and all resources are cleaned up when the server `finished`
promise resolves -- we use a Rust-side server refcount for this.
Performance impact: does not appear to affect basic serving performance
by more than 1% (~126k -> ~125k)

LSP testing APIs now obey the various file inclusion settings:
- Modules shown in the text explorer now respect the `exclude`,
`test.exclude` and `test.include` fields in `deno.json`, as well as
`deno.enablePaths` in VSCode settings.
- Modules with testing code lens now respect the `"exclude"`,
`test.exclude` and `test.include` fields in `deno.json`. Code lens
already respects `deno.enablePaths`.
This allows us to opt in to extremely detailed tracing from dependency
libraries, like so:
```
cargo run --features tracing/log,tracing/max_level_trace -- test --log-level=trace -A --unstable ./cli/tests/unit/serve_test.ts
```
It will not impact normal operation as it requires the
`tracing/max_level_trace` and `tracing/log` to be active.
Note that tracing is already a dependency -- this just makes it a direct
dep of cli so we can access its features more easily.
Fixes https://github.com/denoland/deno/issues/19816
In that issue, I suggest switching over the other brotli functionality
to the Rust API provided by the `brotli` crate. Here, I only do that
with the `brotli_decompress` function to fix the bug with buffers longer
than 4096 bytes.
Previously we pre-computed enabled paths into `Config::enabled_paths`,
and had to keep updating it. Now we determine enabled paths directly
from `Config::settings` on demand as a single source of truth.
Removes `Config::root_uri`. If `InitializeParams::rootUri` is given, and
it doesn't correspond to a folder in
`InitializeParams::workspaceFolders`, prepend it to
`Config::workspace_folders` as a mocked folder.
Includes groundwork for
https://github.com/denoland/vscode_deno/issues/908. In a minor version
cycle or two we can fix that in vscode_deno, and it won't break for Deno
versions post this patch due to the corrected deserialization logic for
`enablePaths`.
Keys are expensive metadata. We track it for various purposes, e.g.
transaction conflict check, and key expiration.
This patch limits the total key size in an atomic operation to 80 KiB
(81920 bytes). This helps ensure efficiency in implementations.
Fixes #19802.
Properly respect when clients do not have the `workspace/configuration`
capability, a.k.a. when an editor cannot provide scoped settings on
request from the LSP.
- Fix one spot where we weren't checking for the capability before
sending this request.
- For `enablePaths`, fall back to the settings passed in the
initialization options in more cases.
- Respect the `workspace/configuration` capability in the test harness
client.
See:
https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#workspace_configuration.
Closes #14122.
Adds two extensions to `--allow-run` behaviour:
- When `--allow-run=foo` is specified and `foo` is found in the `PATH`
at startup, `RunDescriptor::Path(which("foo"))` is added to the
allowlist alongside `RunDescriptor::Name("foo")`. Currently only the
latter is.
- When run permission for `foo` is queried and `foo` is found in the
`PATH` at runtime, either `RunDescriptor::Path(which("foo"))` or
`RunDescriptor::Name("foo")` would qualify in the allowlist. Currently
only the latter does.
Previously:
```rust
pub struct TestDefinition {
pub id: String,
pub name: String,
pub range: SourceRange,
pub steps: Vec<TestDefinition>,
}
pub struct TestDefinitions {
pub discovered: Vec<TestDefinition>,
pub injected: Vec<lsp_custom::TestData>,
pub script_version: String,
}
```
Now:
```rust
pub struct TestDefinition {
pub id: String,
pub name: String,
pub range: Option<Range>,
pub is_dynamic: bool, // True for 'injected' module, not statically detected but added at runtime.
pub parent_id: Option<String>,
pub step_ids: HashSet<String>,
}
pub struct TestModule {
pub specifier: ModuleSpecifier,
pub script_version: String,
pub defs: HashMap<String, TestDefinition>,
}
```
Storing the test tree as a literal tree diminishes the value of IDs,
even though vscode stores them that way. This makes all data easily
accessible from `TestModule`. It unifies the interface between
'discovered' and 'injected' tests. This unblocks some enhancements wrt
syncing tests between the LSP and extension, such as this TODO:
61f08d5a71/client/src/testing.ts (L251-L259)
and https://github.com/denoland/vscode_deno/issues/900. We should also
get more flexibility overall.
`TestCollector` is cleaned up, now stores a `&mut TestModule` directly
and registers tests as it comes across them with
`TestModule::register()`. This method ensures sanity in the redundant
data from having both of `TestDefinition::{parent_id,step_ids}`.
All of the messy conversions between `TestDescription`,
`LspTestDescription`, `TestDefinition`, `TestData` and `TestIdentifier`
are cleaned up. They shouldn't have been using `impl From` and now the
full list of tests is available to their implementations.
We never want tests to hit the real npm registry because this causes
test flakes. In addition, we set a sentinal "unset" value for
`NPM_CONFIG_REGISTRY` to ensure that all tests requiring npm go through
the test server.
Adds `runtime/shared.rs` which is imported by both `build.rs` and the
rest of the crate, containing utilities used by both.
Renames the `snapshot_from_snapshot` feature to
`exclude_runtime_main_js` since that's what it does and it's relevant
outside of snapshotting when `__runtime_js_sources` is specified.
The fix for #20188 was not entirely correct -- we were unlocking the
global buffer incorrectly. This PR introduces a lock state that ensures
we only unlock a lock we have taken out.
When a TCP connection is force-closed (ie: browser refresh), the
underlying future we pass to Hyper is dropped which may cause us to try
to drop the body resource while the OpState lock is still held.
Preconditions for this bug to trigger:
- The body resource must have been taken
- The response must return a resource (which requires us to take the
OpState lock)
- The TCP connection must have been dropped before this
Fixes #20315 and #20298
The motivation is If I'm using deno lint --rules, I want to see all the
rules especially the one that have no tags, since the recommend ones are
already active
This change also prints the tags associated with the rule inline.

We have our own setting for `suggest.completeFunctionCalls`, which must
be enabled:
```js
{
"deno.suggest.completeFunctionCalls": true,
// Re-implementation of:
// "javascript.suggest.completeFunctionCalls": true,
// "typescript.suggest.completeFunctionCalls": true,
}
```
But before this commit the actual implementation had been left as a TODO.
This PR adds a test reporter for the [Test Anything
Protocol](https://testanything.org).
It makes the following implementation decisions:
- No TODO pragma, as there is no such marker in `Deno.test`
- SKIP pragma for `ignore`d tests
- Test steps are treated as TAP14 subtests
- Support for this in consumers seems spotty
- Some consumers will incorrectly interpret these markers, resulting in
unexpected output
- Considering the lack of support, and to avoid implementation
complexity,
subtests are at most one level deep (all test steps are in the same
subtest)
- To accommodate consumers that use comments to indicate test-suites
(unspecced)
- The test module path is output as a comment
- This is disabled for `--parallel` testing
- Failure diagnostics are output as JSON, which is also valid YAML
- The structure is not specified, so the format roughly follows the spec
example:
```

This patch adds a `remote` backend for `ext/kv`. This supports
connection to Deno Deploy and potentially other services compatible with
the KV Connect protocol.
Few improvements to FFI types:
1. Export `PointerObject` for convenience. It's fairly commonly used in
library code and thus should be exported.
2. Fix various comments around `PointerValue` and `UnsafePointer` and
expand upon them to better reflect reality.
3. Instead of using a `Record<"value", type>[T]` for determining the
type of an FFI symbol parameter use direct `T extends "value" ? type :
never` comparison.
The last part enables smuggling extra information into the parameter and
return value string declarations at the type level. eg. Instead of just
`"u8"` the parameter can be `"u8" & { [brand]: T }` for some `T extends
number`. That `T` can then be extracted from the parameter to form the
TypeScript function's parameter or return value type. Essentially, this
enables type-safe FFI!
The foremost use-cases for this are enums and pointer safety. These are
implemented in the second commit which should enable, in a backwards
compatible way, for pointer parameters to declare what sort of pointer
they mean, functions to declare what the API definition of the native
function is, and for numbers to declare what Enum they stand for (if
any).
Deno.serve's fast streaming implementation was not keeping the request
body resource ID alive. We were taking the `Rc<Resource>` from the
resource table during the response, so a hairpin duplex response that
fed back the request body would work.
However, if any JS code attempted to read from the request body (which
requires the resource ID to be valid), the response would fail with a
difficult-to-diagnose "EOF" error.
This was affecting more complex duplex uses of `Deno.fetch` (though as
far as I can tell was unreported).
Simple test:
```ts
const reader = request.body.getReader();
return new Response(
new ReadableStream({
async pull(controller) {
const { done, value } = await reader.read();
if (done) {
controller.close();
} else {
controller.enqueue(value);
}
},
}),
```
And then attempt to use the stream in duplex mode:
```ts
async function testDuplex(
reader: ReadableStreamDefaultReader<Uint8Array>,
writable: WritableStreamDefaultWriter<Uint8Array>,
) {
await writable.write(new Uint8Array([1]));
const chunk1 = await reader.read();
assert(!chunk1.done);
assertEquals(chunk1.value, new Uint8Array([1]));
await writable.write(new Uint8Array([2]));
const chunk2 = await reader.read();
assert(!chunk2.done);
assertEquals(chunk2.value, new Uint8Array([2]));
await writable.close();
const chunk3 = await reader.read();
assert(chunk3.done);
}
```
In older versions of Deno, this would just lock up. I believe after
23ff0e722e, it started throwing a more
explicit error:
```
httpServerStreamDuplexJavascript => ./cli/tests/unit/serve_test.ts:1339:6
error: TypeError: request or response body error: error reading a body from connection: Connection reset by peer (os error 54)
at async Object.pull (ext:deno_web/06_streams.js:810:27)
```
