@Stebalien let me know if this looks like the right approach |

You can just pass pm.OnTimeout (without the function)

Let's take the time once. Or just use the time from the timer.

Concerned that doing this after sending the request could cause us to handle this after receiving the response.

Raised OOB by @dirkmc: we need a single channel to prevent reordering.

Raised OOB in a call: We need to handle cancels. To do that, we're probably going to have to track every request.

This approach doesn't really provide enough protection against misbehaving peers for it to be worth it. For example a peer can timeout on half the requests and still remain in the session. Instead we plan to use the existing DONT_HAVE timeout tracking that we apply to older peers, and simply apply that to newer peers also. Closing in favour of #284 |
Fixes ipfs/boxo#125
