This commit adds sync versions of async APIs to "Deno.permissions"
namespace.
Following APIs were added:
- "Deno.permissions.querySync"
- "Deno.permissions.requestSync"
- "Deno.permissions.revokeSync"
Allows to change behavior of `deno fmt` to use "ASI" setting for
semicolons instead of always prefering them, this is done
by "--options-semi=asi" flag or `"semi": "asi"` setting
in the config file.
This commit removes "Deno.core" namespace. It is strictly private API
that has no stability guarantees, we were supposed to remove it long time ago.

The way the standalone mode handles the `--cert` flag is different to
all other modes. This is because `--cert` takes a path to the
certificate file, which is directly added to the root cert store; except
for compile mode, where its byte contents are stored in the standalone
metadata, and they are added to the root cert store after the
`ProcState` is created.
This change instead changes `Flags::ca_file` (an `Option<String>`) into
`Flags::ca_data`, which can represent a `String` file path or a
`Vec<u8>` with the certificate contents. That way, standalone mode can
create a `ProcState` whose root cert store alreay contains the
certificate.
This change also adds a tests for certificates in standalone mode, since
there weren't any before.
This refactor will help with implementing web workers in standalone mode
in the future.
Updated third_party dlint to v0.37.0 for GitHub Actions. This PR
includes following changes:
* fix(prefer-primordials): Stop using array pattern assignments
* fix(prefer-primordials): Stop using global intrinsics except for
`SharedArrayBuffer`
* feat(guard-for-in): Apply new guard-for-in rule
The leading cause of the problem was that `handleResponse` has
`tryRespondChunked` passed as an argument, which in turn is implemented
as a call to `core.ops.op_try_flash_respond_chuncked`, that throws in
the repro code.
`handleResponse` was not handled correctly, as it not returned any
value, and had no `catch` attached to it.
It also effectively was never correctly handled inside two other blocks
with `resp.then` and `PromisePrototypeCatch(PromisePrototypeThen(resp,
"..."))` as well, as it just short-circuited the promise with an empty
resolve, instead of relying on the last `(async () => {})` block.
This change makes `handleResponse` return a correct value and attach
`onError` handler to the "non-thenable" variant of response handling
code.
This commit changes "ProcState" to store "file_fetcher" field in an "Arc",
allowing it to be preserved between restarts and thus keeping the state
alive between the restarts. File watchers for "deno test" and "deno bench"
now reset "ProcState" between restarts.
This commit changes signature of "deno_core::ModuleLoader::resolve" to pass
an enum indicating whether or not we're resolving a specifier for dynamic import.
Additionally "CliModuleLoader" was changes to store both "parent permissions" (or
"root permissions") as well as "dynamic permissions" that allow to check for permissions
in top-level module load an dynamic imports.
Then all code paths that have anything to do with Node/npm compat are now checking
for permissions which are passed from module loader instance associated with given
worker.
Turns out we were cloning permissions which after prompting were discarded,
so the state of permissions was never preserved. To handle that we need to store
all permissions behind "Arc<Mutex<>>" (because there are situations where we
need to send them to other thread).
Testing and benching code still uses "Permissions" in most places - it's undesirable
to share the same permission set between various test/bench files - otherwise
granting or revoking permissions in one file would influence behavior of other test
files.
Previously, `Deno.permissions.[revoke|request]()` wouldn't correctly
process the `path: URL` when `name` was `ffi`. This change fixes that
behaviour and adds a new function, `formDescriptor()`, to ensure `URL`
arguments are consistently handled across
`Deno.permissions.[query|revoke|request]()`.
This commit fixes "Add all missing imports" quick fix; before
it was replacing all occurrences with the same specifier. Now
every line returned from TSC is processed individually.
This commit adds "Deno.Conn.ref()" and "Deno.Conn.unref()" methods.
These methods can be used to make connection block or not block the
event loop from finishing. Refing/unrefing only influences "read"
operations - ie. scheduling writes to a connection _do_ keep event
loop alive.

This commit fixes handling of rejected promises in dynamic imports
evaluation.
Previously we were running callbacks for next ticks and macrotasks
_before_ polling
dynamic imports and checked for unhandled rejections immediately after.
This is wrong,
as `unhandledrejection` event is dispatched and its callbacks are run as
macrotasks.
This commit changes order of actions performed by the event loop to
following:
- poll async ops
- poll dynamic imports
- run next tick callbacks
- run macrotask callbacks
- check for unhandled promise rejections
This commit fixes formatting of JSError with "errors" property. Before this
commit all instances of "Error" were treated as if they were "AggregateError"
if they had "errors" property. After this commit only actual instances of
"AggregateError" are formatted in such a way, while instances of "Error"
that have "errors" property are formatted without showing details of "errors".
Previously, errored streaming response bodies did not cause the HTTP
stream to be aborted. It instead caused the stream to be closed gracefully,
which had the result that the client could not detect the difference
between a successful response and an errored response.
This commit fixes the issue by aborting the stream on error.
Right now an error in a request body stream causes an uncatchable
global promise rejection. This PR fixes this to instead propagate the
error correctly into the promise returned from `fetch`.
It additionally fixes errored readable stream bodies being treated as
successfully completed bodies by Rust.
This commit changes implementation of "Deno.memoryUsage()" to return
correct value for "rss" field. To do that we implement a specialized function
per os to retrieve this information.
This commit adds new "--inspect-wait" flag which works similarly
to "--inspect-brk" in that it waits for inspector session to be
established before running code. However it doesn't break on the first
statement of user code, but instead runs it as soon as a session
is established.
This commit removes three unstable Deno APIs:
- "Deno.spawn()"
- "Deno.spawnSync()"
- "Deno.spawnChild()"
These APIs were replaced by a unified "Deno.Command" API.
This allows the user to completely opt out from the lock file or rename
it without having to use `--no-lock` and/or `--lock` in all commands.
## Don’t Use Lock File
```json
{
"lock": false
}
```
## Use Lock File With a Different Name
```json
{
"lock": "deno2.lock"
}
```
The CLI args `--no-lock` and `--lock` will always override what is in
the config file.

This commit changes "deno repl" command to run with no permissions by
default and accept "--allow-*" flags.
This change is dictated by the fact that currently there is no way to
run REPL with limited permissions. Technically it's a breaking
change in the CLI command, but there's agreement in the team
that it has merit and it's a good solution.
Running just "deno" command still starts the REPL with full permissions
allowed, but now a banner is printed to inform users about that:
This commit adds "InspectorTester" struct which is used in
inspector tests - it encapsulated various functionalities that
we need (like reading/writing to WebSocket), but also adds
better error handling which should help with debugging flaky
tests.
Previously the inner request object of the original and the new request
were the same, causing the requests to be entangled and mutable changes
to one to be visible to the other. This fixes that.
Currently runtime exception are only displayed at the program end in
terminal, which makes it only a partial fix, as a full fix requires
https://github.com/denoland/rusty_v8/pull/1149 which adds new bindings
to the inspector that allows to notify it about thrown exceptions.
This will be handled in a follow up commit.
This commit completely rewrites inspector session polling.
Until now, there was a single function responsible for polling inspector
sessions which could have been called when polling the "JsRuntime"
as well as from internal inspector functions. There are some cases
where it's required to have reentrant polling of sessions (eg. when
"debugger" statement is run) which should be blocking until inspector
sends appropriate message to continue execution. This was not possible
before, because polling of sessions didn't have reentry ability.
As a consequence, session polling was split into two separate functions:
a) one to be used when polling from async context (on each tick of event
loop in "JsRuntime")
b) one to be used when polling synchronously and potentially blocking
(used by various inspector methods).
There are further cleanups and simplifications to be made in inspector
code, but this rewrite solves the problem at hand (being able to
evaluate
"debugger" JS statement and continue inspector functionality).

Since "Deno.spawn()", "Deno.spawnSync()" and "Deno.spawnChild"
are getting deprecated, this commits rewrites all tests and utilities to
use "Deno.Command" API instead.
This commit updates unhelpful messages that are raised when event loop
stalls on unresolved top-level promises.
Instead of "Module evaluation is still pending but there are no pending
ops or dynamic imports. This situation is often caused by unresolved
promises." and "Dynamically imported module evaluation is still pending
but there are no pending ops. This situation is often caused by
unresolved promises." we are now printing a message like:
error: Top-level await promise never resolved
[SOURCE LINE]
^
at [FUNCTION NAME] ([FILENAME])
eg:
error: Top-level await promise never resolved
await new Promise((_resolve, _reject) => {});

Refactors the `Deno.Command` class to not handle any state, but only being an intermediary to calling its methods, and as such any methods and properties besides `output`, `outputSync` & `spawn` have been removed. Interracting with a `spawn`ed subprocess now works by using the methods and properties on the returned class of the `spawn` method.
…ed promises in mind (#16616)"
This reverts commit fd023cf793.
There are reports saying that Vite is often hanging in 1.28.2 and this
is
the only PR that changed something with HTTP server. I think we should
hold off on trying to fix this and instead focus on #16787
CC @magurotuna
This commit changes "JsRuntime" to send "executionContextDestroyed"
notification when the program finishes and shows a prompt informing
that runtime is waiting for inspector to disconnect.
This PR resets the revert commit made by #16610, bringing back #16383
which attempts to fix the issue happening when we use the flash server
with `--watch` option enabled.
Also, some code changes are made to pass the regression test added in
#16610.
This code checks if permission flags are incorrectly defined after the
module name (e.g. `deno run mod.ts --allow-read` instead of the correct
`deno run --allow-read mod.ts`). If so, a simple warning is displayed.
For CommonJS packages we were not trying different extensions for files
specified as subpath of the package ([package_name]/[subpath]).
This commit fixes that.
If "--lock-write" flag was present we never passed instance of the lockfile to
the npm resolver, which made it skip adding discovered npm packages to
the lockfile. This commit fixes that, by always passing lockfile to the npm
resolver and only regenerating resolver snapshot is "--lock-write" is not
present.
Closes https://github.com/denoland/deno/issues/16666
Supports package names that aren't all lowercase.
This stores the package with a leading underscore (since that's not
allowed in npm's registry and no package exists with a leading
underscore) then base32 encoded (A-Z0-9) so it can be lowercased and
avoid collisions.
Global cache dir:
```
$DENO_DIR/npm/registry.npmjs.org/_{base32_encode(package_name).to_lowercase()}/{version}
```
node_modules dir `.deno` folder:
```
node_modules/.deno/_{base32_encode(package_name).to_lowercase()}@{version}/node_modules/<package-name>
```
Within node_modules folder:
```
node_modules/<package-name>
```
So, direct childs of the node_modules folder can have collisions between
packages like `JSON` vs `json`, but this is already something npm itself
doesn't handle well. Plus, Deno doesn't actually ever resolve to the
`node_modules/<package-name>` folder, but just has that for
compatibility. Additionally, packages in the `.deno` dir could have
collissions if they have multiple dependencies that only differ in
casing or a dependency that has different casing, but if someone is
doing that then they're already going to have trouble with npm and they
are asking for trouble in general.
If resolving types for an npm package, we didn't find "types" entry in
the conditional exports declaration we were falling-through to regular
resolution, instead of short-circuiting and giving up on resolving
types, which might lead to unwarranted errors.

1. There was a lot of cloning going on with `NpmPackageInfo`. This is
now stored in an `Arc<NpmPackageInfo>` and cloning only happens on the
individual version.
2. The package cache is now cleared from memory after resolution.
3. This surfaced a bug in `deno cache` and I noticed it can be more
efficient if we have multiple root specifiers if we provide all the
specifiers as roots.
This PR adds copies of several unstable APIs that are available
in "Deno[Deno.internal].nodeUnstable" namespace.
These copies do not perform unstable check (ie. don't require
"--unstable" flag to be present). Otherwise they work exactly
the same, including permission checks.
These APIs are not meant to be used by users directly and
can change at any time.
Copies of following APIs are available in that namespace:
- Deno.spawnChild
- Deno.spawn
- Deno.spawnSync
- Deno.serve
- Deno.upgradeHttpRaw
- Deno.listenDatagram
This commit makes "npm:" specifiers not require "--unstable" flag.
At the moment some APIs used by Node polyfills still require
"--unstable" which will be addressed in follow up PRs.
This adds support for peer dependencies in npm packages.
1. If not found higher in the tree (ancestor and ancestor siblings),
peer dependencies are resolved like a dependency similar to npm 7.
2. Optional peer dependencies are only resolved if found higher in the
tree.
3. This creates "copy packages" or duplicates of a package when a
package has different resolution due to peer dependency resolution—see
https://pnpm.io/how-peers-are-resolved. Unlike pnpm though, duplicates
of packages will have `_1`, `_2`, etc. added to the end of the package
version in the directory in order to minimize the chance of hitting the
max file path limit on Windows. This is done for both the local
"node_modules" directory and also the global npm cache. The files are
hard linked in this case to reduce hard drive space.
This is a first pass and the code is definitely more inefficient than it
could be.
Closes #15823
This commit fixes CJS resolution when there's a local "node_modules/"
directory.
Before this commit relative imports from CJS files where resolved
relative to
root directory of the package instead of relative to referrer file.
When streaming a resource in ext/http, with compression enabled, we
didn't flush individual chunks. This became very problematic when we
enabled `req.body` from `fetch` for FastStream recently.
This commit now correctly flushes each resource chunk after compression.
