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.
* perf(runtime/fs): optimize readFile by using a single large buffer
* handle extended/truncated files during read
Allocate an extra byte in our read buffer to detect "overflow" then fallback to unsized readAll for remainder of extended file, this is a slowpath that should rarely happen in practice
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"
}
}
}
Async WebAssembly compilation was implemented by adding two
bindings: `set_wasm_streaming_callback`, which registered a callback to
be called whenever a streaming wasm compilation was started, and
`wasm_streaming_feed`, which let the JS callback modify the state of the
v8 wasm compiler.
`set_wasm_streaming_callback` cannot currently be implemented as
anything other than a binding, but `wasm_streaming_feed` does not really
need to use anything specific to bindings, and could indeed be
implemented as one or more ops. This PR does that, resulting in a
simplification of the relevant code.
There are three operations on the state of the v8 wasm compiler that
`wasm_streaming_feed` allowed: feeding new bytes into the compiler,
letting it know that there are no more bytes coming from the network,
and aborting the compilation. This PR provides `op_wasm_streaming_feed`
to feed new bytes into the compiler, and `op_wasm_streaming_abort` to
abort the compilation. It doesn't provide an op to let v8 know that the
response is finished, but closing the resource with `Deno.core.close()`
will achieve that.
A comment in `runtime.js` reads that `console` seems to be "the only one
that should be writable and non-enumerable", which explains why it is
declared with `util.writable` but then has its property descriptor's
`enumerable` key changed to false.
But it is not in fact true that `console` is the only global property
for which this holds, and it wasn't even when this behavior was
introduced in denoland#9013. All WebIDL interfaces are also writable and
non-enumerable – the only difference here being that `console` is a
namespace rather than an interface.
Since WebIDL interfaces are defined with `util.nonEnumerable`, and
`console` uses the same descriptor keys, this PR changes the definition
of `console` to use `util.nonEnumerable` as well.
