(#12549)
This commit integrates import map and "classic" resolutions in
the "--compat" mode when using ES modules; in effect
"http:", "https:" and "blob:" imports now work in compat mode.
The algorithm works as follows:
1. If there's an import map, try to resolve using it and if succeeded
return the specifier
2. Try to resolve using "Node ESM resolution", and if succeeded return
the specifier
3. Fall back to regular ESM resolution

Closes #11826
**BREAKING CHANGE** this behaviour was disable when introduced in Deno 1.14/TypeScript 4.4. It will highlight code that unsafely handles variables that are caught, and will cause type errors in unsafe code.

Closes #11882
BREAKING CHANGE: Previously when `--location` was set, the unique storage key was derived from the the URL of the location instead of just the origin. This change correctly uses just the origin. This may cause previously persisted storage to change its key and data to not be available with the same location as before.

This commit adds CJS and ESM Node resolvers to the "--compat" mode.
The functionality is spread across "cli/compat" module and Node compatibility
layer in "deno_std/node"; this stems from the fact that ES module resolution
can only be implemented in Rust as it needs to directly integrated with
"deno_core"; however "deno_std/node" already provided CJS module resolution.
Currently this resolution is only active when running a files using
"deno run --compat --unstable <filename>", and is not available in other
subcommands, which will be changed in follow up commits.

Returns empty values in case of errors, source lines are non-essential anyway. These errors can happen e.g. when source files change at runtime. A warning is also printed to help us track when it happens in unexpected cases besides this.

This commit fixes problem with LSP where diagnostics coming
from "deno lint" don't respect configuration file.
LSP was changed to store "Option<ConfigFile>", "Option<LintConfig>"
and "Option<FmtConfig>" on "Inner"; as well as storing "Option<LintConfig>"
and "Option<FmtConfig>" on "StateSnapshot".

with `util.writable()` (#12378)
`Window`'s `self` property and `DedicatedWorkerGlobalScope`'s `name`
property are defined as Web IDL read-only attributes with the
`[Replaceable]` extended attribute, meaning that their setter will
redefine the property as a data property with the set value, rather than
changing some internal state. Deno currently defines them as read-only
data properties instead.
Given that Web IDL requires all attributes to be accessor properties
rather than data properties, but Deno exposes almost all of those
properties as either read-only or writable data properties, it makes
sense to expose `[Replaceable]` properties as writable as well – as is
already the case with `WindowOrWorkerGlobalScope`'s `performance`
property.

WebAssembly modules compiled through `WebAssembly.compile()` and similar
non-streaming APIs don't have a URL associated to them, because they
have been compiled from a buffer source. In stack traces, V8 will use
a URL such as `wasm://wasm/d1c677ea`, with a hash of the module.
However, wasm modules compiled through streaming APIs, like
`WebAssembly.compileStreaming()`, do have a known URL, which can be
obtained from the `Response` object passed into the streaming APIs. And
as per the developer-facing display conventions in the WebAssembly
Web API spec, this URL should be used in stack traces. This change
implements that.

(#12348)
This reverts commit d5b38a992933db5cb2d0221e9d82af191022dad5.

This commit adds automatic injection of Node globals when "--compat" flag
is present.
This is done by executing "https://deno.land/std/node/global.ts" as a "side module",
before main module is executed.
This commit makes "--compat" required to be used with "--unstable" flag, as some
of Node globals require unstable Deno APIs.
|
|
|
|
Adds support for "node:" prefix for Node built-ins in "--compat" mode.
As per https://nodejs.org/api/esm.html#esm_node_imports
|
|
|
|
This commit adds "--compat" flag. When the flag is passed a set of mappings for
built-in Node modules is injected into the import map. If user doesn't
explicitly provide an import map (using "--import-map" flag) then a map is
created on the fly. If there are already existing mappings in import map that
would clash with built-in Node modules a set of diagnostics is printed to the
terminal with suggestions how to proceed.

USVString for Response constructor (#12201)
|
|
Before #12156, closing a worker which had children would cause a panic
(https://github.com/denoland/deno/issues/11342#issuecomment-918327693).
After that PR, closing a worker will also close any child workers.
|
|
|
|
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 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"
}
}
