`InvalidDNSNameError` is thrown when a string is not a valid hostname,
e.g. it contains invalid characters, or starts with a numeric digit. It
does not involve a (failed) DNS lookup.
denort is an optimization to "deno compile" to produce slightly smaller
output. It's a decent idea, but causes a lot of negative side-effects:
- Deno's link time is a source of constant agony both locally and in CI,
denort doubles link time.
- The release process is a long and arduous undertaking with many manual
steps. denort necessitates an additional manual zip + upload from M1
apple computers.
- The "deno compile" interface is complicated with the "--lite" option.
This is confusing for uses ("why wouldn't you want lite?").
The benefits of this feature do not outweigh the negatives. We must find
a different approach to optimizing "deno compile" output.
This commits adds adds "permissions" option to the test definitions
which allows tests to run with different permission sets than
the process's permission.
The change will only be in effect within the test function, once the
test has completed the original process permission set is restored.
Test permissions cannot exceed the process's permission.
You can only narrow or drop permissions, failure to acquire a
permission results in an error being thrown and the test case will fail.
Even if bootstrapping the JS runtime is low level, it's an abstraction leak of
core to require users to call `Deno.core.ops()` in JS space.
So instead we're introducing a `JsRuntime::sync_ops_cache()` method,
once we have runtime extensions a new runtime will ensure the ops
cache is setup (for the provided extensions) and then loading/unloading
plugins should be the only operations that require op cache syncs
- register builtin v8 errors in core.js so consumers don't have to
- remove complexity of error args handling (consumers must provide a
constructor with custom args, core simply provides msg arg)
This commit aligns the `fetch` API and the `Request` / `Response`
classes belonging to it to the spec. This commit enables all the
relevant `fetch` WPT tests. Spec compliance is now at around 90%.
Performance is essentially identical now (within 1% of 1.9.0).
This commit fixes the URL returned from `request.url` in the HTTP server
to be fully qualified. This previously existed, but was removed and
accidentially not readded during optimizations of the HTTP ops.
Returning a non fully qualified URL from `Request#url` is not spec
compliant.
The panic was caused by the lack of an error class mapping for
futures::channel::TrySendError, but it shouldn't have been throwing an error in
the first place - when a worker has terminated, postMessage should just return.
The issue was that the termination message hadn't yet been recieved, so it was
carrying on with trying to send the message. This adds another check on the Rust
side for if the channel is closed, and if it is the worker is treated as
terminated.
This commit aligns `Headers` to spec. It also removes the now unused
03_dom_iterable.js file. We now pass all relevant `Headers` WPT. We do
not implement any sort of header filtering, as we are a server side
runtime.
This is likely not the most efficient implementation of `Headers` yet.
It is however spec compliant. Once all the APIs in the `HTTP` hot loop
are correct we can start optimizing them. It is likely that this commit
reduces bench throughput temporarily.
Raise the soft limit to the hard limit when possible. This is similar
to what Node.js does to avoid running into "out of file descriptors"
errors too quickly.
On most Linux systems, raises the limit from 1,024 to 1,048,576.
On most macOS systems, raises the limit from 256 to 10,240.
Fixes #10148.
This stabilizes Deno.ftruncate and Deno.ftruncateSync.
This is a well known system call and the interface is
not going to change. Implicitly requires write permissions
as the file has to be opened with write to be truncated.
This commit adds allowlist support to `--allow-run` flag.
Additionally `Deno.permissions.query()` allows to query for specific
programs within allowlist.
This commit adds blob URL support. Blob URLs are stored in a process
global storage, that can be accessed from all workers, and the module
loader. Blob URLs can be created using `URL.createObjectURL` and revoked
using `URL.revokeObjectURL`.
This commit does not add support for `fetch`ing blob URLs. This will be
added in a follow up commit.
This commit marks the `Deno.iter` and `Deno.iterSync` utils as
deprecated, and schedules them for removal in Deno 2.0. These
utilities are implemented in pure JS, so should not be part of the
Deno namespace.
These utilities are now available in std/io/util:
denoland/deno_std#843.
This commit marks the `Deno.Buffer` / `Deno.readAll` /
`Deno.readAllSync` / `Deno.writeAll` / `Deno.writeAllSync` utils as
deprecated, and schedules them for removal in Deno 2.0. These
utilities are implemented in pure JS, so should not be part of the
Deno namespace.
These utilities are now available in std/io/buffer and std/io/util:
https://github.com/denoland/deno_std/pull/808.
This additionallty removes all internal dependance on Deno.Buffer.
- Improves op performance.
- Handle op-metadata (errors, promise IDs) explicitly in the op-layer vs
per op-encoding (aka: out-of-payload).
- Remove shared queue & custom "asyncHandlers", all async values are
returned in batches via js_recv_cb.
- The op-layer should be thought of as simple function calls with little
indirection or translation besides the conceptually straightforward
serde_v8 bijections.
- Preserve concepts of json/bin/min as semantic groups of their
inputs/outputs instead of their op-encoding strategy, preserving these
groups will also facilitate partial transitions over to v8 Fast API for the
"min" and "bin" groups
This commit moves implementation of bin ops to "deno_core" crates
as well as unifying logic between bin ops and json ops to reuse
as much code as possible (both in Rust and JavaScript).
This patch doesn't actually fix the bug I was hoping to fix, which is
that `update_diagnostics()` sometimes gets called even when there are
more updates that should be processed first. I did eventually figure out
that this issue is caused by Tokio's cooperative yielding, which
currently can't be disabled.
However overall it makes the debounce code somewhat more readable IMO,
which is why I'm suggesting to land it anyway.
Change `Console.#printFunc` to pass a log level as the second argument
(0 = debug, 3 = error), instead of a boolean for `isErr`. This does not
change the Deno runtime behaviour at all.
This commit rewrites "dispatch_minimal" into "dispatch_buffer".
It's part of an effort to unify JS interface for ops for both json
and minimal (buffer) ops.
Before this commit "minimal ops" could be either sync or async
depending on the return type from the op, but this commit changes
it to have separate signatures for sync and async ops (just like
in case of json ops).
This commit starts splitting out the deno_web op crate into multiple
smaller crates. This commit splits out WebIDL and URL API, but in the
future I want to split out each spec into its own crate. That means we
will have (in rough order of loading): `webidl`, `dom`, `streams`,
`console`, `encoding`, `url`, `file`, `fetch`, `websocket`, and
`webgpu` crates.
This commit rewrites implementation of "JsRuntime::mod_evaluate".
Event loop is no longer polled automatically and users must manually
drive event loop forward after calling "mod_evaluate".

This commit updates implementation of import maps to
align it to current revision of the spec.
Existing tests were removed in favor of using suite from
WPT.
This commit changes formatting of JS errors; by not showing
source lines for internal code. Where possible, instead using
the top stack frame associated with user code i.e. the first
location that is colourful and not a "deno:" URL.
This commit makes "Deno.link" and "Deno.linkSync" stable.
The permission required has been changed to read-write to
ensure one cannot escape the sandbox.
This commit adds support for type definitions in "deno doc";
with this change "deno doc" is able to leverage the same directives
as TS compiler.

This commit adds a new subcommand called "coverage"
which can generate code coverage reports to stdout in
multiple formats from code coverage profiles collected to disk.
Currently this supports outputting a pretty printed diff and
the lcov format for interoperability with third-party services and tools.
Code coverage is still collected via other subcommands
that run and collect code coverage such as
"deno test --coverage=<directory>" but that command no
longer prints a pretty printed report at the end of a test
run with coverage collection enabled.
The restrictions on which files that can be reported on has
also been relaxed and are fully controllable with the include
and exclude regular expression flags on the coverage subcommand.

This commit removes redundant "--reload" args because "util::deno_cmd"
recreates "DENO_DIR".
This commit also fixes ta_reload in integration tests to actually test reload.
This adds an exit sanitizer to ensure that code being tested or
dependencies of that code can't accidentally call "Deno.exit"
leading to partial test runs and false results.
This commit rewrites "JsRuntime::poll" function to fix a corner case that
might caused "overflown_response" to be overwritten by other overflown response.
The logic has been changed to allow returning multiple overflown response
alongside responses from shared queue.
This PR deprecates the "--ts"/"-T" flag of "deno eval" (which will later be removed in 2.0)
and introduces "--ext" which is used by "deno fmt" for content type selection.
This is to ensure we have a single flag that can be used across subcommands
to select the language (JS/TS).
Currently if WebSocket is closed without code, it will error
while on Chrome it would close with code 1005 instead.

This commit adds support for formatting JSON and JSONC
in "deno fmt".
New values "json" and "jsonc" are added to "--ext" flag for
standard input processing.
This commit adds support for loading import maps from URLs,
both remote and local.
This feature is supported in CLI flag as well as in runtime
compiler API.
This PR makes json_op_sync/async generic to all Deserialize/Serialize types
instead of the loosely-typed serde_json::Value. Since serde_json::Value
implements Deserialize/Serialize, very little existing code needs to be updated,
however as json_op_sync/async are now generic, type inference is broken in some
cases (see cli/build.rs:146). I've found this reduces a good bit of boilerplate,
as seen in the updated deno_core examples.
This change may also reduce serialization and deserialization overhead as serde
has a better idea of what types it is working with. I am currently working on
benchmarks to confirm this and I will update this PR with my findings.
When we migrated away from all the locks, there was a regression that
was not caught immediately. The tsc::get_asset() would attempt to modify
the snapshot, but the problem was that the snapshot was a .clone() of
the inner language server's assets, which meant that modifications to
that where lost. When we then attempted to do a hover on those assets,
the inner language servers assets didn't have the retrieved asset, and
therefore would throw an error.
Commit 2828690fc ("fix(lsp): fix deadlocks, use one big mutex") from
last month introduced a regression in asset cache lookups where results
of lazy caching were lost due to operating on a copy of the asset cache.
This commit fixes that by copying the asset from the copy to the real
cache.
The mutex was used to hide the fact that the Sources object mutates
itself when it's queried. Be honest about that and mark everything that
directly or indirectly mutates it as `mut`.
This is a follow-up to commit 2828690fc7
from last month ("fix(lsp): fix deadlocks, use one big mutex (#9271)")
