Fixes#481.
Prior to this commit, payments stored in the channel DB only kept a
record of the payment hash. This is a problem as the preimage is what
serves as proof of payment and a user should be able to look up this
value in the future (not just immediately after payment).
Instead of storing both the payment hash and the preimage, we store the
preimage only since the hash can be derrived from this using a SHA256.
In the RPC listpayments command, we now give the preimage in addition to
the payment hash.
This modifies the tests that deal serializing the Invoice type to limit
the creation date to seconds since Go1.9 added the concept of a
monotonic component to times which does not round trip through
MarshalBinary and UnmarshalBinary and therefore causes the tests to fail.
In particular, it modifies the creation dates in the randInvoice,
makeFakePayment, makeRandomFakePayment, and TestInvoiceWorkflow
functions.
This results in allowing TestOutgoingPaymentSerialization,
TestOutgoingPaymentWorkflow, and TestInvoiceWorkflow to pass.
This commit removes all instances of the fastsha256 library and
replaces it with the sha256 library in the standard library. This
change should see a number of performance improvements as the standard
library has highly optimized assembly instructions with use vectorized
instructions as the platform supports.
This commit modifies the new payment module within the database to
match the coding style of the rest of the package and the project as a
hole. Additionally, a few fields have been renamed, and the extra
timestamp added to the OutgoingPayment struct has been removed as
there’s already a CreationTime field within the Invoice struct that’s
embedded within the OutgoingPayment struct.
Go-fmt files. Refactored code according to the guidelines.
Enhanced payment test: add error checking
and individual context for each API call.
Add Timestamp field to payment struct.
