Why are we using Symbol.for here?

I used the similar pattern to what we followed over here #46205 (comment)

@aduh95 I presume Node.js streams or another part that exists both in core and userland added this for interoperability (so that require("node:stream") and require("readable-stream") interoperate) and then everyone (probably me too) saw the code and cargo culted. Probably a bunch at the point we moved private variables to symbols when privates were not supported in snapshots back then.

It's also arguably easier to debug "from the outside" but not by a considerable margin.

Added more few more tests should be covering most scenarios

Neat (I'm +1 on this and approving). I'll add some questions later.

Hey, consider going through the standards track and adding this to streams through WHATAG (like a signal parameter to the constructor). This is not instead of this PR but in addition.

Can you also please add to the docs for addAbortSignal at stream.md ?

jasnell · 2023-01-22T19:24:15Z

~~The docs for addAbortSignal needs to be updated also~~

Heh, jinx.

Adding!

Hi so are you thinking something like new ReadableStream({ signal: ac.signal })

jasnell · 2023-01-22T19:36:58Z

Adding a signal to the ReadableStream constructor is not something I would really expect to see happen in whatwg, particularly since there is already a way of cancelling the stream via the existing API. Could be worth a try but I'd be surprised if it were accepted.

debadree25 · 2023-01-22T19:51:47Z

Have added to docs @benjamingr @jasnell

Can you add an history entry in the YAML comment please?

debadree25 · 2023-01-23T08:28:58Z

What should the version be v19.5.0?

aduh95 · 2023-01-23T08:45:59Z

What should the version be v19.5.0?

It should be REPLACEME:

           `vcbuild.bat lint` on Windows). If you are adding to or deprecating an API, 
        
           add or change the appropriate YAML documentation. Use `REPLACEME` for the 
        
           version number in the documentation YAML:
