* src: throw DataCloneError on transfering untransferable objectsChengzhong Wu2023-05-051-0/+2
| | | | | | | | | | | | The HTML StructuredSerializeWithTransfer algorithm defines that when an untransferable object is in the transfer list, a DataCloneError is thrown. An array buffer that is already transferred is also considered as untransferable.

* worker: add setEnvironmentData/getEnvironmentDataJames M Snell2021-03-151-0/+4
| | | | | | | | | | | | | | | | | | These APIs allow arbitrary, cloneable JavaScript values to be set and passed to all new Worker instances spawned from the current context. It is similar to `workerData` except that environment data is set independently of the `new Worker()` constructor, and the the value is passed automatically to all new Workers. This is a *partial* fix of https://github.com/nodejs/node/issues/30992 but does not implement a complete fix.

* worker: add public method for marking objects as untransferableAnna Henningsen2020-06-251-1/+6
| | | | | | | | | | | | | | | We currently mark a number of `ArrayBuffer`s as not transferable, including the `Buffer` pool and ones with finalizers provided by C++ addons. There is no good reason to assume that userland code might not encounter similar problems, for example when doing `ArrayBuffer` pooling similar to ours. Therefore, provide an API that lets userland code also mark objects as not transferable.

* worker: add ability to unshift message from MessagePortAnna Henningsen2019-05-191-0/+2
| | | | | | | | | | | | | | | | In combination with Atomics, this makes it possible to implement generic synchronous functionality, e.g. `importScript()`, in Workers purely by communicating with other threads. This is a continuation of https://github.com/nodejs/node/pull/26686, where a preference for a solution was voiced that allowed reading individual messages, rather than emitting all messages through events.

* worker: use copy of process.envAnna Henningsen2019-03-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | Instead of sharing the OS-backed store for all `process.env` instances, create a copy of `process.env` for every worker that is created. The copies do not interact. Native-addons do not see modifications to `process.env` from Worker threads, but child processes started from Workers do default to the Worker’s copy of `process.env`. This makes Workers behave like child processes as far as `process.env` is concerned, and an option corresponding to the `child_process` module’s `env` option is added to the constructor.
