Release v0.4.20

[Stebalien]

I promised a short release and got distracted. Luckily, @whyrusleeping came to the rescue so we're going to cut a release ASAP (RC1 on Wednesday).

The primary features will be:

1. Bitswap memory fixes.
2. Bitswap reduced provider workers.
3. Immediate providing of root blocks (with an on-disk provider queue).
4. Several panic fixes in the DHT.
5. Some NAT traversal improvements.
6. Reduced autonat delays. (probably needs a go mod update)
7. ipfs add [--nocopy] URL.
8. GO MODULES!

What am I missing?

TODOs:

• Update to go 1.12 (Switch to Go 1.12 #6144) tests are failing which is disturbing. (@Kubuxu is awesome)
• All the memory leaks!
  • Goroutine leak leads to OOM  #6166 - relay and modernize request handling libp2p/go-ws-transport#41
  • Deadlocks and memory leaks #6168 - Update quic-go libp2p/go-libp2p-quic-transport#53
• LevelDB panic #6146 (may be a memory corruption issue) no idea
• Make sure to update go-libp2p for ERROR basichost: DiscoverNAT error: no NAT found natmgr.go:96 #6142.
• Update badger (for new memory improvements) - dep: update badger go-ds-badger#57
• Merge feat(coreapi): tag all explicit connect requests in the connection manager #6171 to tame the connection manager a bit.
• Pull through the autorelay/autonat delay fixes if they're finished in time. - parallelize dialbacks libp2p/go-libp2p-autonat#20, Reduce autorelay boot delay and correctly handle private->public transition libp2p/go-libp2p#570

"What am I missing?"

Is there any way we can add a generation of PeerId through HTTP-RPC by supplying a public key?
I am struggling to obtain the feedback for the proposal: #6152

[CoreyLin]

@Stebalien Just want to confirm with you that v0.4.20 will be released today(3rd April), right? Thanks. I am waiting to use your latest release. 😃

[lordcirth]

@CoreyLin He said release candidate 1 on Wednesday.

[CoreyLin]

@lordcirth @Stebalien OK. So the release date is not finalized, right?

[olizilla]

Update to IPFS Web UI 2.4.4! I'll PR now.

[olizilla]

Done: #6169

[Stebalien]

@reardenlife I'm trying to avoid "one more thinging" this release.

@CoreyLin it'll be released when it's ready but I'm planning on cutting an RC1 today.

[raulk]

@Stebalien at the risk of “one more thinging”(tm), exposing peer protection as a swarm command would be welcome by users and infra: libp2p/go-libp2p-connmgr#36 it’s low risk as it doesn’t interfere with existing functionality nor the main loop

[Stebalien]

I'd like to avoid shipping a new command at this point. However, we can ship a custom build to infra.

[Stebalien]

OK, so the RC1's going to be coming tomorrow. I'd really like to get that QUIC fix in at least.

[vyzo]

Please also include an update of the go-libp2p-autonat-svc dependency (now at v0.0.4), as it cuts down the dialback timeout to 15s. The bootstrappers will also need to be updated for the new release.

[vyzo]

Note that I have tagged v0.0.4 in go-libp2p.

[Stebalien]

@vyzo done.

[Stebalien]

Status: wrestling with the distribution scripts and go modules (and trying not to break rebuilding of old versions with gx).

[lordcirth]

Are there any known issues with rc1 that need fixing?
