This commit changes implementation of top-level-await in "deno_core".
Previously promise returned from module evaluation was not awaited,
leading to out-of-order execution of modules that have TLA. It's been
fixed by changing "JsRuntime::mod_evaluate" to be an async function
that resolves when the promise returned from module evaluation also
resolves. When waiting for promise resolution event loop is polled
repeatedly, until there are no more dynamic imports or pending
ops.
* Revert "refactor: Worker is not a Future (#7895)"
This reverts commit f4357f0ff9.
* Revert "refactor(core): JsRuntime is not a Future (#7855)"
This reverts commit d8879feb8c.
* Revert "fix(core): module execution with top level await (#7672)"
This reverts commit c7c7677825.
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 commit renames occurrences of "isolate" variable name
to "js_runtime". This was outstanding debt after renaming
deno_core::CoreIsolate to JsRuntime.
This commit fixes implementation of top level await in "deno_core".
Previously promise returned from module execution was ignored causing to execute
modules out-of-order.
With this commit promise returned from module execution is stored on "JsRuntime"
and event loop is polled until the promise resolves.
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 commits removes "CompilerWorker" in favor of
using "JsRuntime".
"cli/ops/compiler.rs" has been removed in favor of inline
registration of ops in "cli/tsc.rs"
- 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"
Moves op_close and op_resources to deno_core::ops and exports them.
Adds serde dependency to deno_core and reexports it.
Moves JS implementation of those ops to Deno.core and reexports them in Deno.
Removes:
- "deno_core::StartupData"
- "deno_core::Script"
- "deno_core::OwnedScript"
Changes to "JsRuntime":
- remove "new_with_loader()"
- remove "with_heap_limits()"
- rename "IsolateOptions" to "RuntimeOptions" and make public
- "JsRuntime::new()" takes "RuntimeOptions" as a single param
Provides a concrete state type that can be dynamically added. This is necessary for op crates.
* renames BasicState to OpState
* async ops take `Rc<RefCell<OpState>>`
* sync ops take `&mut OpState`
* removes `OpRegistry`, `OpRouter` traits
* `get_error_class_fn` moved to OpState
* ResourceTable moved to OpState
deno_core/
- rename core_isolate.rs to runtime.rs
- rename CoreIsolate to JsRuntime
- rename JSError to JsError
- rename JSStackFrame to JsStackFrame
cli/
- update references from deno_core::CoreIsolate to deno_core::JsRuntime
- rename deno_core::JSError to deno_core::JsError
- rename fmt_errors::JSError to fmt_errors::JsError
* refactor "compile" and "runtimeCompile" in "compiler.ts" and factor out
separate methods for "compile" and "bundle" operations
* remove noisy debug output from "compiler.ts"
* provide "Serialize" implementations for enums in "msg.rs"
* rename "analyze_dependencies_and_references" to "pre_process_file" and
move it to "tsc.rs"
* refactor ModuleGraph to use more concrete types and properly annotate
locations where errors occur
* remove dead code from "file_fetcher.rs" - "SourceFile.types_url" is no
longer needed, as type reference parsing is done in "ModuleGraph"
* remove unneeded field "source_path" from ".meta" files stored for
compiled source file (towards #6080)
Currently sync operations on stdin are failing because tokio::Stdin
cannot be converted to a std::File.
This commit replaces tokio::stdin with a raw file descriptor
wrapped in a std::fs::File which can be converted to a
tokio::File and back again making the synchronous version
of op_read actually work.
This commit completely overhauls how module analysis is
performed in TS compiler by moving the logic to Rust.
In the current setup module analysis is performed using
"ts.preProcessFile" API in a special TS compiler worker
running on a separate thread.
"ts.preProcessFile" allowed us to build a lot of functionality
in CLI including X-TypeScript-Types header support
and @deno-types directive support. Unfortunately at the
same time complexity of the ops required to perform
supporting tasks exploded and caused some hidden
permission escapes.
This PR introduces "ModuleGraphLoader" which can parse
source and load recursively all dependent source files; as
well as declaration files. All dependencies used in TS
compiler and now fetched and collected upfront in Rust
before spinning up TS compiler.
To achieve feature parity with existing APIs this commit
includes a lot of changes:
* add "ModuleGraphLoader"
- can fetch local and remote sources
- parses source code using SWC and extracts imports, exports, file references, special
headers
- this struct inherited all of the hidden complexity and cruft from TS version and requires
several follow up PRs
* rewrite cli/tsc.rs to perform module analysis upfront and send all required source code to
TS worker in one message
* remove op_resolve_modules and op_fetch_source_files from cli/ops/compiler.rs
* run TS worker on the same thread
This PR hot-fixes permission escapes in dynamic imports, workers
and runtime compiler APIs.
"permissions" parameter was added to public APIs of SourceFileFetcher
and appropriate permission checks are performed during loading of
local and remote files.
Importing .wasm files is non-standardized therefore deciding to
support current functionality past 1.0 release is risky.
Besides that .wasm import posed many challenges in our codebase
due to complex interactions with TS compiler which spawned
thread for each encountered .wasm import.
This commit removes:
- cli/compilers/wasm.rs
- cli/compilers/wasm_wrap.js
- two integration tests related to .wasm imports
This PR removes op_cache and refactors how Deno interacts with TS compiler.
Ultimate goal is to completely sandbox TS compiler worker; it should operate on
simple request -> response basis. With this commit TS compiler no longer
caches compiled sources as they are generated but rather collects all sources
and sends them back to Rust when compilation is done.
Additionally "Diagnostic" and its children got refactored to use "Deserialize" trait
instead of manually implementing JSON deserialization.
This change is to prevent needed a separate stat syscall for each file
when using readdir.
For consistency, this PR also modifies std's `WalkEntry` interface to
extend `DirEntry` with an additional `path` field.
* Properly track isFile, isSymlink, isDirectory
These don't exhaust all the possibilities, so none of them should be
defined as "neither of the others".
* empty
This is a first pass implementation which is still missing several important
features:
- support for --inspect-brk (#4503)
- support for source maps (#4501)
- support for piping console.log to devtools console (#4502)

This a complex boring PR that shifts around code (primarily) in cli/fs.rs and
cli/ops/fs.rs. The gain of this refactoring is to ease the way for #4188 and
#4017, and also to avoid some future development pain.
Mostly there is no change in functionality. Except:
* squashed bugs where op_utime and op_chown weren't using `resolve_from_cwd`
* eliminated the use of the external `remove_dir_all` crate.
* op_chmod now only queries metadata to verify file/dir exists on Windows (it
will already fail on Unix if it doesn't)
* op_chown now verifies the file/dir's existence on Windows like chmod does.
Fixes#4101
Previously, we would just provide the raw JSON to the TypeScript
compiler worker, but TypeScript does not transform JSON. This caused
a problem when emitting a bundle, that the JSON would just be "inlined"
into the output, instead of being transformed into a module.
This fixes this problem by providing the compiled JSON to the TypeScript
compiler, so TypeScript just sees JSON as a "normal" TypeScript module.
Listener and UDPConn are AsyncIterables instead of AsyncIterators.
The [Symbol.asyncIterator]()s are defined as generators and the
next() methods are gone.
"Listener/Socket has been closed" errors are now BadResource.
There's a lot of variation in doc comments and internal code about
whether the first parameter to file system calls is `path` or `name` or
`filename`. For consistency, have made it always be `path`.
Rewrite "normalize_path()" to remove all intermediate components from the path, ie. "./" and "../". It's very similar in functionality to fs::canonicalize(), however "normalize_path() doesn't resolve symlinks.
To better reflect changes in error types in JS from #3662 this PR changes
default error type used in ops from "ErrBox" to "OpError".
"OpError" is a type that can be sent over to JSON; it has all
information needed to construct error in JavaScript. That
made "GetErrorKind" trait useless and so it was removed altogether.
To provide compatibility with previous use of "ErrBox" an implementation of
"From<ErrBox> for OpError" was added, however, it is an escape hatch and
ops implementors should strive to use "OpError" directly.
Example:
$ python2 -c 'open("\x80\x7F", "w")'
$ deno eval 'Deno.readDirSync(".")'
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', cli/ops/fs.rs:373:16
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
fatal runtime error: failed to initiate panic, error 5
Aborted (core dumped)
Before this commit they made deno panic, now they are silently skipped.
Not ideal but arguably better than panicking.
No test because what characters are and aren't allowed in filenames is
highly file system-dependent.
Closes#3950
* establish basic event loop for workers
* make "self.close()" inside worker
* remove "runWorkerMessageLoop() - instead manually call global function
in Rust when message arrives. This is done in preparation for structured clone
* refactor "WorkerChannel" and use distinct structs for internal
and external channels; "WorkerChannelsInternal" and "WorkerHandle"
* move "State.worker_channels_internal" to "Worker.internal_channels"
* add "WorkerEvent" enum for child->host communication;
currently "Message(Buf)" and "Error(ErrBox)" variants are supported
