Update runtimes to polkadot-v0.9.40

[ebma]

We should update our runtime dependencies to version polkadot-v0.9.38 so that we get rid of some dependency conflicts.
For example, we were running into problems because our spacewalk pallets use jsonrpsee with version >0.16.0 but other parachain pallets that are on polkadot-v0.9.37 still use jsonrpsee version 0.15.x (e.g. Zenlink) which then leads to conflicts when importing RPC modules from their pallets.

Hey team! Please add your planning poker estimate with Zenhub @ashneverdawn @ebma @RustNinja @TorstenStueber

Maybe it makes sense to even switch to Polkadot version 0.9.40 now – it is already supported by orml.

This would also require a follow up task to not just execute the runtime upgrade but first to redeploy all of our collator nodes.

[ebma]

Sure, we'd just need to double-check the jsonrpsee dependencies but if there is a mismatch, then probably just because the version used in the spacewalk pallets is 'too old' which we can fix easily.

I created a polkadot-v0.9.40 branch in substrate-stellar-sdk repository so that we are good to go from that side. Probably also need to update dependencies in the other related dependencies:

• https://github.com/pendulum-chain/oracle-pallet
• https://github.com/pendulum-chain/Zenlink-DEX-Module
• https://github.com/pendulum-chain/bifrost

[TorstenStueber]

For that reason I want to re-estimate. @vadaynujra is such a feature not available (change an estimate)?

[b-yap]

@TorstenStueber including https://github.com/pendulum-chain/spacewalk, right?

[b-yap]

Yes I would think this will be higher than 3. The jump from .37 to .40 is huge.

A few changes I found:

• rename grandpa crates
• rename random-collective-flip crates
• Weight's from_ref_time() is deprecated, so we have to rerun that one again

And there's plenty more.
Currently on https://github.com/pendulum-chain/oracle-pallet.

[TorstenStueber]

@b-yap yes, also including Spacewalk of course. Seems like I have the power to change the estimate. Shall we change it to 5 then @b-yap, or even 8?

[b-yap]

8 would be fine.

[TorstenStueber]

Alright, done.

[Curu24]

Hello, will this include --rpc-relay-chain-url functionality?

[TorstenStueber]

@Curu24 Is this a new feature introduced in Substrate recently? Can you refer to it please?

Since this feature has been merged already many months ago, it is already included in the polkadot-v0.9.31 branch.

So, it looks to me like the Pendulum nodes would already include this functionality even without this PR.

Oh, yes, sorry. You're right. I was trying with the older release 0.9.29. With 0.9.37 it works.
