2022-06-13Deno.exit() is an alias to self.close() in worker contexts (#14826)Bartek Iwańczuk
This commit changes Deno.exit() to be an alias to self.close() in worker contexts, and the provided exit code becomes is ignored.

2022-05-17BREAKING(unstable): Enable Deno namespace in workers by default (#14581)Nayeem Rahman
This commit removes "WorkerOptions.deno" option as a boolean, as well as "WorkerOptions.deno.namespace" settings. Starting with this commit all workers have access to "Deno" namespace by default.

2022-04-27fix(workers): Make `worker.terminate()` not block the current thread (#13941)Andreu Botella
Calling `worker.terminate()` used to kill the worker's isolate and then block until the worker's thread finished. This blocks the calling thread if the worker's event loop was blocked in a sync op (as with `Deno.sleepSync`), which wasn't realized at the time, but since the worker's isolate was killed at that moment, it would not block the calling thread if the worker was in a JS endless loop. However, in #12831, in order to work around a V8 bug, worker termination was changed to first set a signal to let the worker event loop know that termination has been requested, and only kill the isolate if the event loop has not finished after 2 seconds. However, this change kept the blocking, which meant that JS endless loops in the worker now blocked the parent for 2 seconds. As it turns out, after #12831 it is fine to signal termination and even kill the worker's isolate without waiting for the thread to finish, so this change does that. However, that might leave the async ops that receive messages and control data from the worker pending after `worker.terminate()`, which leads to odd results from the op sanitizer. Therefore, we set up a `CancelHandler` to cancel those ops when the worker is terminated.

This commit: - removes "fmt_errors::PrettyJsError" in favor of "format_js_error" fn - removes "deno_core::JsError::create" and "deno_core::RuntimeOptions::js_error_create_fn" - adds new option to "deno_runtime::ops::worker_host::init"

2022-02-11compat: support --compat in web workers (#13629)Bartek Iwańczuk
Adds another callback to WebWorkerOptions that allows to execute some modules before actual worker code executes. This allows to set up Node global using std/node.

2021-12-11fix: op_set_exit_code (#13034)Bartek Iwańczuk
Fixes "op_set_exit_code" by sharing a single "Arc" between all workers (via "op state") instead of having a "global" value stored in "deno_runtime" crate. As a consequence setting an exit code is always scoped to a tree of workers, instead of being overridable if there are multiple worker tree (like in "deno test --jobs" subcommand). Refactored "cli/main.rs" functions to return "Result<i32, AnyError>" instead of "Result<(), AnyError>" so they can return exit code.

2021-09-22fix(workers): Don't panic when a worker's parent thread stops running (#12156)Andreu Botella
This panic could happen in the following cases: - A non-fatal error being thrown from a worker, that doesn't terminate the worker's execution, but propagates to the main thread without being handled, and makes the main thread terminate. - A nested worker being alive while its parent worker gets terminated. - A race condition if the main event loop terminates the worker as part of its last task, but the worker doesn't fully terminate before the main event loop stops running. This panic happens because a worker's event loop should have pending ops as long as the worker isn't closed or terminated – but if an event loop finishes running while it has living workers, its associated `WorkerThread` structs will be dropped, closing the channels that keep those ops pending. This change adds a `Drop` implementation to `WorkerThread`, which terminates the worker without waiting for a response. This fixes the panic, and makes it so nested workers are automatically terminated once any of their ancestors is closed or terminated. This change also refactors a worker's termination code into a `WorkerThread::terminate()` method. Closes #11342. Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com>
2021-09-06Don't drop messages from workers that have already been closed (#11913)Andreu Botella
When `worker.terminate()` is called, the spec requires that the corresponding port message queue is emptied, so no messages can be received after the call, even if they were sent from the worker before it was terminated. The spec doesn't require this of `self.close()`, and since Deno uses different channels to send messages and to notify that the worker was closed, messages might still arrive after the worker is known to be closed, which are currently being dropped. This change fixes that. The fix involves two parts: one on the JS side and one on the Rust side. The JS side was using the `#terminated` flag to keep track of whether the worker is known to be closed, without distinguishing whether further messages should be dropped or not. This PR changes that flag to an enum `#state`, which can be one of `"RUNNING"`, `"CLOSED"` or `"TERMINATED"`. The Rust side was removing the `WorkerThread` struct from the workers table when a close control was received, regardless of whether there were any messages left to read, which made any subsequent calls to `op_host_recv_message` to return `Ok(None)`, as if there were no more mesasges. This change instead waits for both a close control and for the message channel's sender to be closed before the worker thread is removed from the table.
2021-08-16feat(runtime): support classic workers for internal testing (#11338)Andreu Botella
This commit implements classic workers, but only when the `--enable-testing-features-do-not-use` flag is provided. This change is not user facing. Classic workers are used extensively in WPT tests. The classic workers do not support loading from disk, and do not support TypeScript. Co-authored-by: Luca Casonato <hello@lcas.dev>

This commit removes implementation of "native plugins" and replaces it with FFI API. Effectively "Deno.openPlugin" API was replaced with "Deno.dlopen" API.

2021-04-25feat(cli): add test permissions to Deno.test (#10188)Casper Beyer
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.

2021-03-31refactor: new optimized op-layer using serde_v8 (#9843)Aaron O'Mullan
- 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

2021-01-06feat: Add configurable permissions for Workers (#8215)Steven Guerrero
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).
