feat: go-libp2p v0.21 (rcmgr auto scaling) #9074

marten-seemann · 2022-07-02T13:04:25Z

Updates to go-libp2p v0.21.
Updates the rcmgr.
Enables better metrics around the rcmgr.

Before merge:

Chore: update to go-libp2p 0.21 libp2p/go-libp2p-kad-dht#784
make a new release for kad-dht

-		})
-		return result, err
-
+		return result, mgr.ViewTransient(func(s network.ResourceScope) error { return getLimit(s) })
 	case strings.HasPrefix(scope, config.ResourceMgrServiceScopePrefix):


Do we have to worry about spans here?

core/node/libp2p/rcmgr.go

core/node/libp2p/rcmgr_defaults.go

core/node/libp2p/rcmgr_defaults.go

-	defaultLimits.SystemBaseLimit.Conns = defaultLimits.SystemBaseLimit.ConnsOutbound + defaultLimits.SystemBaseLimit.ConnsInbound
-
-	return defaultLimits
+	// if cfg.ConnMgr.Type == "basic" {


This was weird. I would expect the resource manager be the ultimate arbiter, not connmgr.

We need something analogous though. The connection manager limit needs to be in sync with resource manager limit.

If these two are out of sync which should be the source of truth?

Probably the rcmgr, just because it's configuration is so much more complex. If I remember correctly, there were plans to deprecate the connmgr watermark configuration options in go-ipfs.

marten-seemann · 2022-07-03T10:46:10Z

core/node/libp2p/rcmgr_defaults.go

-	libp2p.SetDefaultServiceLimits(testLimiter)
+	l := rcmgr.DefaultLimits
+	libp2p.SetDefaultServiceLimits(&l)
+	limits := l.AutoScale()


Note: AutoScale dedicates 1/8 of the system memory to libp2p (which effects how many conns / streams / memory etc.) will be allowed. This might be too little for a standalone go-ipfs node, and too much for IPFS Desktop / Brave.

@lidel Do you have any "profile" setting that we can use here?

We do have a server profile which is used for adjusting specific config values as one-time change against Kubo config.

I think it is ok to go with AutoScale and revisit profile-specific defaults when in separate PR, as part of work towards enabling ResourceMgr by default (tracked in #8761)

MarcoPolo · 2022-07-04T16:01:09Z

Running this here: https://ipfs.marcopolo.io/d/MgmGIjjnk/resource-manager?orgId=1

MarcoPolo · 2022-07-06T19:12:33Z

There are two failures related to the new base256 emoji multibase: https://app.circleci.com/pipelines/github/ipfs/go-ipfs/7123/workflows/c0a0abf6-7f82-4965-8004-1413388e36fa/jobs/77371?invite=true#step-111-13053

I'm going to assign these bugs to @Jorropo since he added that multibase and the fix isn't super trivial since it involves updating some assumptions we've made in the sharness tests.

MarcoPolo · 2022-07-25T17:52:30Z

rebased on v0.14.0 After tests pass I'll ask bifrost to deploy this on bank4 for smoke testing

MarcoPolo · 2022-08-11T20:23:51Z

We should merge libp2p/go-libp2p-kad-dht#784 and make a new release first

MarcoPolo · 2022-08-11T20:24:44Z

I randomly picked @aschmahmann for a reviewer here, but feel free to reassign.

MarcoPolo · 2022-08-15T21:14:39Z

@lidel This is ready for a review, thanks!

Thank you @MarcoPolo, I believe this is ok to be included in 0.15-rc1

ResourceMgr.Enabled defaults to false, which makes rcmgr-related changes in this PR low risk.
Work towards enabling it by default we will continue #8761

fysa small changes I've made:

docs for Swarm.ResourceMgr.Allowlist
regression test so we can detect when rcmgr metrics disappear
backed out goleveldb bump (rationale below)

lidel · 2022-08-16T22:20:35Z

go.mod

-	github.com/syndtr/goleveldb v1.0.0
+	github.com/prometheus/common v0.35.0 // indirect
+	github.com/stretchr/testify v1.8.0
+	github.com/syndtr/goleveldb v1.0.1-0.20210819022825-2ae1ddf74ef7


⚠️
I am unsure why this was bumped:

go-libp2p itself uses v.1.0.0?

this impacts plugin/plugins/levelds, which still uses v1.0.0 – safer to use the same version

Ideally, we would remove this dependency, and use aliases similar to this one

Since we have no time to deal with this,
I've reverted to v1.0.0 in a42848a just to play this safe.

Thanks for the flag, I’m also unsure why this was bumped
