[rexhoffman]

@zekun000 :D this something you can take on?

[rexhoffman]

And if not, who in networking should?

[zekun000]

maybe @bmwill or @metajack ?

[rexhoffman]

I'll look in to it since I don't expect much action otherwise, but shouldn't networking/consensus take ownership of the tokio crate?

[metajack]

Pinging @phlip9 from networking.

[rexhoffman]

I think it's likely too early to try to get this in. Too many other deps require tokio and mismatches seems to occur.

[zekun000]

but shouldn't networking/consensus take ownership of the tokio crate?

why?

[metajack]

They are the main consumers of tokio.

The dev-infra team does not have the bandwidth to carefully manage every dependency. We need to spread this load over all of the core infra team.

[zekun000]

I don't disagree with spreading the load and happy to help, but that doesn't affect the ownership. async is a fundamental piece of the language, if devinfra is responsible for rust, it probably should own tokio.

[phlip9]

This might be a bit early, we probably need to wait for some of our dependencies to update:

• h2: (merged 29 days ago) update to tokio 0.3 hyperium/h2#491
• hyper: (merged 8 days ago) Tokio 0.3 Upgrade hyperium/hyper#2319
• tokio-tungstenite: (merged 28 days ago) Update tokio to 0.3 snapview/tokio-tungstenite#125
• reqwuest: (blocked) Update to tokio 1.0, bytes 1.0 seanmonstar/reqwest#1076
• rusoto: (blocked) Dependency upgrade requests for 0.46 rusoto/rusoto#1852
• warp: (blocked) Upgrade to Tokio 1.0 seanmonstar/warp#753

Edit: possibly also some more since the bytes crate updated to v0.6.0.
Edit: rusoto is only used by cluster-test, so it's probably not blocking us.

Agreed, we need to wait till more of the ecosystem has updated
