Most common argument to `env` option for `worker_threads.Worker` will be
`process.env`.
In Deno `process.env` is a `Proxy` which can't be cloned using
structured clone algorithm.
So to be safe, I'm creating a copy of actual object before it's sent to
the worker thread.
Ref #23522
Closes https://github.com/denoland/deno/issues/23362
Previously we were panicking if there was a pending read on a
port and `receiveMessageOnPort` was called. This is now fixed
by cancelling the pending read, trying to read a message and
resuming reading in a loop.
MessagePort if directly assigned to workerData property instead of
embedding it in an object then it is not patched to a NodeMessagePort.
This commit fixes the bug.
This commit fixes race condition in "node:worker_threads" module were
the first message did a setup of "threadId", "workerData" and
"environmentData".
Now this data is passed explicitly during workers creation and is set up
before any user code is executed.

This commit changes how we figure out if we're running on main
thread in `node:worker_threads` module. Instead of relying on quirky
"magic variable" for a name to check if we're on main thread, we are
now explicitly passing this information during bootstrapping of the
runtime. As a side effect, `WorkerOptions.name` is more useful
and matches what Node.js does more closely (though not fully).
Towards https://github.com/denoland/deno/issues/22783
Follow up to #22157.
This leaves us with 4 usages of `ensureFastOps()` in `deno` itself.
There's also about 150 usages of `Deno.core.ops.<op_name>` left as well.
This PR ensures that node's `worker_threads` module exports
`MessageChannel`, `MessagePort` and the `BroadcastChannel` API. Fixing
these won't make `esbuild` work, but brings us one step closer 🎉
Fixes #19028 .
This commit renames "deno_core::InternalModuleLoader" to
"ExtModuleLoader" and changes the specifiers used by the
modules loaded from this loader to "ext:".
"internal:" scheme was really ambiguous and it's more characters than
"ext:", which should result in slightly smaller snapshot size.
Closes https://github.com/denoland/deno/issues/18020
This commit changes "include_js_files!" macro from "deno_core"
in a way that "dir" option doesn't cause specifiers to be rewritten
to include it.
Example:
```
include_js_files! {
dir "js",
"hello.js",
}
```
The above definition required embedders to use:
`import ... from "internal:<ext_name>/js/hello.js"`.
But with this change, the "js" directory in which the files are stored
is an implementation detail, which for embedders results in:
`import ... from "internal:<ext_name>/hello.js"`.
The directory the files are stored in, is an implementation detail and
in some cases might result in a significant size difference for the
snapshot. As an example, in "deno_node" extension, we store the
source code in "polyfills" directory; which resulted in each specifier
to look like "internal:deno_node/polyfills/<module_name>", but with
this change it's "internal:deno_node/<module_name>".
Given that "deno_node" has over 100 files, many of them having
several import specifiers to the same extension, this change removes
10 characters from each import specifier.
This commit moves "deno_std/node" in "ext/node" crate. The code is
transpiled and snapshotted during the build process.
During the first pass a minimal amount of work was done to create the
snapshot, a lot of code in "ext/node" depends on presence of "Deno"
global. This code will be gradually fixed in the follow up PRs to migrate
it to import relevant APIs from "internal:" modules.
Currently the code from snapshot is not used in any way, and all
Node/npm compatibility still uses code from
"https://deno.land/std/node" (or from the location specified by
"DENO_NODE_COMPAT_URL"). This will also be handled in a follow
up PRs.
