Migration to Pull Streams - Experiment C

[daviddias]

Mode C

This is one of the experiments done in order to test the migration to pull-streams, with regards to stream muxing.

Mode B consists in having pull streams exposed from the spdy stream muxer, while layering spdy on top of Node.js Streams, that are layered on pull-streams, that are layered on Node.js streams. This experiment was created because it represents most of the real scenarios, where we have Node.js streams from the transports and have to convert them to pull-streams for the connection upgrades, secio, etc, but for spdy, we need to convert it back. The problems that this solution presents match the same problems in Mode A.

Illustration:

Notes

• Mid stress tests fail
• Mega stress test runs out of memory if not throttled

How to test it yourself

In order to test this, you need to have to have the pull-streams migration of interface-connection available in your local env. Here are the steps

> git clone [email protected]:libp2p/interface-connection.git -b pull
> cd interface-connection
> npm i && npm link
> cd ..
> git clone [email protected]:libp2p/interface-stream-muxer.git -b pull-mode-c
> cd interface-stream-muxer
> npm i && npm link
> cd ..
> git clone [email protected]:libp2p/js-libp2p-spdy.git -b pull-mode-c
> cd js-libp2p-spdy 
> npm i
> npm link interface-connection
> npm link interface-stream-muxer
> npm test
