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.

This commit fixes a problem where loading and executing multiple
modules leads to all of the having "import.meta.main" set to true.
Following Rust APIs were deprecated:
- deno_core::JsRuntime::load_module
- deno_runtime::Worker::execute_module
- deno_runtime::WebWorker::execute_module
Following Rust APIs were added:
- deno_core::JsRuntime::load_main_module
- deno_core::JsRuntime::load_side_module
- deno_runtime::Worker::execute_main_module
- deno_runtime::Worker::execute_side_module
- deno_runtime::WebWorker::execute_main_module
Trying to load multiple "main" modules into the runtime now results in an
error. If user needs to load additional "non-main" modules they should use
APIs for "side" module.
This commit adds support for configuration file for "deno fmt"
subcommand. It is also respected by LSP when formatting
files.
Example configuration:
{
"fmt": {
"files": {
"include": ["src/"],
"exclude": ["src/testdata/"]
},
"options": {
"useTabs": true,
"lineWidth": 80,
"indentWidth": 4,
"singleQuote": true,
"textWrap": "preserve"
}
}
}
