This commit changes module loading implementation in "deno_core"
to call "ModuleLoader::prepare" hook only once per entry point.
This is done to avoid multiple type checking of the same code
in case of duplicated dynamic imports.
Relevant code in "cli/module_graph.rs" was updated as well.
This commit adds a new `--parent-pid <pid>` flag to `deno lsp` that when provided starts a task that checks for the existence of the provided process id (ex. vscode's) every 30 seconds. If the process doesn't exist (meaning the deno process has nothing interacting with it), then it terminates itself.
This commit moves implementation of "JsRuntimeInspector" to "deno_core" crate.
To achieve that following changes were made:
* "Worker" and "WebWorker" no longer own instance of "JsRuntimeInspector",
instead it is now owned by "deno_core::JsRuntime".
* Consequently polling of inspector is no longer done in "Worker"/"WebWorker",
instead it's done in "deno_core::JsRuntime::poll_event_loop".
* "deno_core::JsRuntime::poll_event_loop" and "deno_core::JsRuntime::run_event_loop",
now accept "wait_for_inspector" boolean that tells if event loop should still be
"pending" if there are active inspector sessions - this change fixes the problem
that inspector disconnects from the frontend and process exits once the code has
stopped executing.
This commit refactors implementation of inspector.
The intention is to be able to move inspector implementation to "deno_core".
Following things were done to make that possible:
* "runtime/inspector.rs" was split into "runtime/inspector/mod.rs"
and "runtime/inspector/server.rs", separating inspector implementation
from Websocket server implementation.
* "DenoInspector" was renamed to "JsRuntimeInspector" and reference to "server"
was removed from the structure, making it independent of Websocket server
used to connect to Chrome Devtools.
* "WebsocketSession" was renamed to "InspectorSession" and rewritten in such
a way that it's not tied to Websockets anymore; instead it accepts a pair
of "proxy" channel ends that allow to integrate the session with different
"transports".
* "InspectorSession" was renamed to "LocalInspectorSession" to better indicate
that it's an "in-memory" session and doesn't require Websocket server. It was
also rewritten in such a way that it uses "InspectorSession" from previous point
instead of reimplementing "v8::inspector::ChannelImpl" trait; this is done by using
the "proxy" channels to communicate with the V8 session.
Consequently "LocalInspectorSession" is now a frontend to "InspectorSession". This
introduces a small inconvenience that awaiting responses for "LocalInspectorSession" requires
to concurrently poll worker's event loop. This arises from the fact that "InspectorSession"
is now owned by "JsRuntimeInspector", which in turn is owned by "Worker" or "WebWorker".
To ease this situation "Worker::with_event_loop" helper method was added, that takes
a future and concurrently polls it along with the event loop (using "tokio::select!" macro
inside a loop).
Replaces the file-backed provider by an in-memory one because proper
file locking is a hard problem that detracts from the proof of concept.
Teach the WPT runner how to extract tests from .html files because all
the relevant tests in test_util/wpt/webmessaging/broadcastchannel are
inside basics.html and interface.html.
Currently file passed to --config file is parsed using TsConfig structure
that does multiple things when loading the file. Instead of relying on that
structure I've introduced ConfigFile structure that can be updated to
sniff out more fields from the config file in the future.
This commit implements file watching for deno test.
When a file is changed, only the test modules which
use it as a dependency are rerun.
This is accomplished by reworking the file watching infrastructure
to pass the paths which have changed to the resolver, and then
constructing a module graph for each test module to check if it
contains any changed files.
This commit adds support for running test in parallel.
Entire test runner functionality has been rewritten
from JavaScript to Rust and a set of ops was added to support reporting in Rust.
A new "--jobs" flag was added to "deno test" that allows to configure
how many threads will be used. When given no value it defaults to 2.
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
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 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 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 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 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).
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 commit adds support for formatting markdown files with "deno fmt".
Additionally "--ext={js|jsx|ts|tsx|md}" flag was added to "deno fmt"
that allows to specify file type when providing contents over stdio.
This commit adds --target and --lite flags to deno compile subcommand.
--target allows to cross-compile binary to different target architectures by
fetching appropriate binary from remote server on first run. All downloaded
binaries are stored in "$DENO_DIR/dl".
--lite allows to use lite version of the runtime (ie. the one that doesn't contain
built-in tooling like formatter or linter).
This commit adds new binary target called "denort".
It is a "lite" version of "deno" binary that can only execute
code embedded inside the binary itself.

When we were doing single process in-memory reports getting the source
from the runtime was practical, but now that we're writing to disk this
conflicts with the format tools taking raw v8 coverage dumps expect.
This commit adds new option to "Worker" Web API that allows to
configure permissions.
New "Worker.deno.permissions" option can be used to define limited
permissions to the worker thread by either:
- inherit set of parent thread permissions
- use limited subset of parent thread permissions
- revoke all permissions (full sandbox)
In order to achieve this functionality "CliModuleLoader"
was modified to accept "initial permissions", which are used
for top module loading (ie. uses parent thread permission set
to load top level module of a worker).
This commit removes "js" module from "cli".
It contained stuff related to TypeScript compiler (snapshot,
declaration files) and thus it was moved to "tsc" module.
This PR refactors "cli/flags.rs" and "runtime/permissions.rs" so
that "allow_read", "allow_write" and "allow_net" themselves
have allowlists, instead of storing them in additional fields.
This commit moves Deno JS runtime, ops, permissions and
inspector implementation to new "deno_runtime" crate located
in "runtime/" directory.
Details in "runtime/README.md".

This commit does major refactor of "Worker" and "WebWorker",
in order to decouple them from "ProgramState" and "Flags".
The main points of interest are "create_main_worker()" and
"create_web_worker_callback()" functions which are responsible
for creating "Worker" and "WebWorker" in CLI context.
As a result it is now possible to factor out common "runtime"
functionality into a separate crate.
This commit makes the file watcher continue to work even if module
resolution fails at the initial attempt, allowing us to execute `run`
or `bundle` subcommand when a script has invalid syntax. In such
cases, the watcher observes a single file that is specified as an
command line argument.
Factored out "init_v8_flags", "init_logger" and
"get_subcommand" from "main" function.
Also "Worker" was removed in favor of moving
logic to "MainWorker" and "WebWorker" respectively.
This commit adds support for "--watch" flag for "bundle"
and "fmt" subcommands.
In addition to this, it refactors "run --watch" command so that
module resolution will occur every time the file watcher detects
file addition/deletion, which allows the watcher to observe a file
that is newly added to the dependency as well.
This commit moves following tools into a single "tools"
module located at "cli/tools/mod.rs":
- formatter
- linter
- test runner
- coverage collector
- installer
- binary upgrader
- repl
This commit renames "fs" module in "cli/" to "fs_util". This is purely
cosmetic change; there were a few places which aliased "crate::fs"
to "deno_fs" which was very confusing with "fs" module in ops.
This commit removes ProgramState::permissions field.
Having permissions parsed from CLI flags stored on globally
accessible state object made it easy to mistakenly use these
permissions in situations which required "runtime" permissions.

This commit rewrites deno::Worker to not implement Future
trait.
Instead there are two separate methods:
- Worker::poll_event_loop() - does single tick of event loop
- Worker::run_event_loop() - runs event loop to completion
Additionally some cleanup to Worker's field visibility was done.
This ports the REPL over to Rust and makes use of an inspector session to run a REPL on top of any isolate which lets make full use of rustylines various things like validators and completors without having to introduce a bunch of hard to test internal ops and glue code.
An accidental but good side effect of this is that the multiple line input we previously had is now an editable multi-line input prompt that is correctly stored in the history as a single entry.
This removes the dependency on global state and instead relies on the
runtime's internal state to get the script sources it saw when it
collected code coverage for them.
- remove "CliState.workers" and "CliState.next_worker_id", instead
store them on "OpState" using type aliases.
- remove "CliState.global_timer" and "CliState.start_time", instead
store them on "OpState" using type aliases.
- remove "CliState.is_internal", instead pass it to Worker::new
- move "CliState::permissions" to "OpState"
- move "CliState::main_module" to "OpState"
- move "CliState::global_state" to "OpState"
- move "CliState::check_unstable()" to "GlobalState"
- change "cli_state()" to "global_state()"
- change "deno_core::ModuleLoader" trait to pass "OpState" to callbacks
- rename "CliState" to "CliModuleLoader"
This reverts the changes introduced by PR #5276, which made
`deno install «script»` automatically bundle the script's dependencies.
It broke the `deno install` command for a large number of scripts.
This reverts commit 34e98fa59c.
