📝 ryanofsky converted_to_draft a pull request: "POC: IPC tracing interface"
(https://github.com/bitcoin/bitcoin/pull/32898)
This a is proof-of-concept adding an IPC interface for tracing as discussed in https://github.com/bitcoin-core/libmultiprocess/issues/185. As mentioned there, this is a naive implementation that would need to be optimized to have good performance, but it does show an end-to-end demo of how tracing could work using IPC.

The can be tested by building with `-DENABLE_IPC=ON` and running:

```bash
build/bin/bitcoin-node -regtest -ipcbind=unix # Start node listening on IPC socket
build/bin/bit

Each transaction now counts as `1 + num_inputs / 10` announcements, accounting for the additional time it takes to do `m_outpoint_to_orphan_it` operations (benchmarks suggest it's roughly 1/10th of the time to do `m_orphans` operations). We round down so that the first 9 inputs are "free" and most normal transactions don't get a "penalty". This means a 9-input transaction has the highest computation time / latency score, which is why the benchmarks use them.

A few pushes ago I changed the lim

@ismaelsadeeq I don't think 1p1c is compatible with this approach at all, unless the connection is intentionally held open long enough for the parent to be fetched from the sending node? Obviously the connection could be held open with additional logic but just pointing this out. A sender-initiated package relay system might be easier to extend (but way out of scope of this PR).

> A few pushes ago I changed the limit back from 24,000 to 3,000 after changing the benchmarks to be more representative of actual worst case and realizing we actually definitely can't handle 24k

Can you recap what the deficiency was?

Thx. It is still relevant but I don't have enough time to tackle it. Up for grabs.

I agree that in this case is useful, but not sure about the other tests. But anyway, since the reorg is the slowest test, running it without reorg should be fine. So we could have just an option to skip it?

I'm (very) open to suggestions on how to make the caching call more robust. (Indeed I expected some.)

There's no performance improvement from this PR, it's the first in a series of proposed changes I'll be making
