With neo-go v0.90.0 there are new event subscription component
and new verification script routines based on NEO3. These features
allow to avoid using low-level neo-vm code in NeoFS and corresponding
projects.
This commit removes unused function:
- FetchPublicKeys (used in neofs indexer),
- VerificationScript (used in KeysToAddress),
- Address (used in KeysToAddress),
- ReversedScriptHashToAddress (used in neofs indexer),
- IsAddress (used in neofs indexer),
- ReverseBytes (used in neofs indexer),
- DecodeScriptHash (used in neofs indexer).
KeysToAddress changed into KeyToAddress because NeoFS won't work with
multisignature owners for now and it is not supported in neo-go library.
In previous implementation service package provided types and functions
that wrapped signing/verification of data with session token.
This allowed us to use these functions for signing / verification of
service requests of other packages. To support the expansion of messages
with additional parts that need to be signed, you must be able to easily
expand the signed data with new parts.
To achieve the described goal, this commit makes the following changes:
* adds GroupSignedPayloads and GroupVerifyPayloads functions;
* renames SignedDataWithToken to RequestData, DataWithTokenSignAccumulator
to RequestSignedData, DataWithTokenSignSource to RequestVerifyData;
* renames SignDataWithSessionToken/VerifyAccumulatedSignaturesWithToken
function to SignRequestData/VerifyRequestData and makes it to use
GroupSignedPayloads/GroupVerifyPayloads internally.
In previous implementation first byte of buffer for HeadRequest
signed payload was set to 1 if FullHeaders flag was set. Otherwise,
this byte remained unchanged. For correct recording of a signed payload,
it is necessary to explicitly set the first byte with the unset flag.
BasicACL have set of rules for every request type. ACL will be
processed before any request specific handlers. Therefore
we need to determine request type in generic request interface,
which is used in pre-processors of object service
implementation.
