OutgoingMessage should not allow writing more bytes than Content-Length

[ronag]

I don't think we currently error if the user specifices a content-length header and then writes more bytes to the response. I think this is something we could detect and error. Some http clients have a hard time handling this case (especially with pipelining) and would be nice if we could help with reducing the probability of this occuring.

@nodejs/http wdyt?

I'm in favor if this is not costing much too much throughput.

I think we should add a new option to enable the check (as a minor), and then make a breaking change to flip that default.

@mcollina @ronag hey, I'm just getting started, do you mind if I try to pull this off?

[daukadolt]

Looks like an interesting ticket, good luck with it @betochf 👍

Please do let me know though in case if I can take over 🙈

May I start working on this issue? As I think I would be able to create a PR for the same.

[manav014]

@ronag may please help me with a specific test case which I can add as a test and also I can use that to test my changes.

[mpodolsk]

if this will be a perf drop, what about a config flag for strict validation?
also this assumes that we know the size of the payload before sending it :) which from exp may not always be the case.
I think its the RECEIVER of the content that should validate the size against the headers. :)

there are very specific conditions when to send this header.

If we consider request payloads "inputs" its the receiving system that should validated those 🤔
