is the manifests of native contracts fixed?

vang1ong7ang · 2024-05-15T06:42:11Z

@Jim8y I think the commit c1af443 introduces trouble

Breaks NeoFS chains immediately. I've tried to explain why we're doing it this way numerous times, but looks like no one cares about NeoFS and compatibility.

breaks neofs or break the mainnet, this is a problem. We will have it but can not make it take effect untill we have the fork.

Please, revert #3172 then. It causes more problems than it solves with this HF logic.

BTW, it can only be exploited by committee. Nasty committee.

BTW, it can only be exploited by committee. Nasty committee.

Hardly ever committee will designate this role before Notary subsystem implementation is finished. Thus, I'd vote for keeping P2PNotary role without binding to hardfork.

BTW, it can only be exploited by committee

Sorry, not exactly. getDesignatedByRole will return empty array instead of failing.

Please, revert #3172 then. It causes more problems than it solves with this HF logic.

I think reverting #3172 is better than fixing. maybe #3172 can be introduced back after there's good way for node upgrading

This reverts commit c1af443.

BTW, this is a part of #3210. Add a reference to the PR description, please.

Also, we need the same functionality to be implemented for events. It's not hard to extend it, read the original issue.

This pr is a hotpatch for the hf issues, i prefer to keep it as simple as possible.

Ref. #3210 (comment) as TODO.

Rename to ActiveTil?

Suggested change

public ContractMethodAttribute(bool isDeprecated, Hardfork deprecatedIn)

public ContractMethodAttribute(Hardfork? activeIn, Hardfork deprecatedIn)

I'd suggest to use this option, and just put null as the first argument for those methods that were always active but need to be deprecated.

Existing solution already works, i may update it after we have confirmed that this pr works fine.

You may safely get rid of NamedCurve type here and use NamedCurveHash, just check that curve falls within the expected range (22 or 23) and throw if not. You can do this because NamedCurveHash is compatible. If you implement this, then no 'NamedCurve' is obsolete linter warnings will be raised.

This is a hotpatch, i prefer to keep it simple and use original logic as much as possible.

Every TODO is an issue, otherwise it won't be done. See #3236.

Good job @Jim8y

The deprecatedIn function was really needed for many cases and pending to be done!

DeprecatedIn hardfork of every native method (if not null) should be included into the set of used hardforks, otherwise no contract update will be performed on this hardfork activation: https://github.com/neo-project/neo/blob/08f2dfc56762bb43be33e873bc3659bad368d4d6/src/Neo/SmartContract/Native/NativeContract.cs#L284 This commit should be a part of #3234 and a part of 3.7.4. Luckily, this new DeprecatedIn functionality is used only for the old native CryptoLib's verifyWithECDsa method with Cockatrice hardfork. And luckily, there are other CryptoLib's methods with ActiveIn set to Cockatrice hardfork. Due to these two facts this bug does not affect mainnet/testnet, and thus we don't need 3.7.5 with this fixincluded, so this fix may safely be postponed to 3.8.0.
