This is a shortcut fix. Instead of replicating the zip244 transaction
logic that's implemented in librustzcash:
zcash_primitives/src/transaction/components/orchard.rs
cheat by calling getblock with verbose level 1, which prints the txid
of each transaction. This currently requires calling getblock twice,
once for the raw hex (as we have always done), and again to get the
transaction IDs. An easy improvement would be to add the raw hex to
verbosity 1 result. (Or have a new verbosity that shows both.)
In previous commit, I forgot to include Orchard transactions in compact
blocks (so they will now include transactions with either Sapling or
Orchard transactions).
This is a non-functional change. Instead of `rawTransaction` (which
carries the result of parsing a full transaction from zcashd) containing
slices of _pointers_ to separately-allocated memory (one allocation for
each spend, for example), allocate a slice of spends (one contiguous
range of memory). A quick benchmark shows sync improves by about 8%.
TODO:
- store, instead of just skip over, nu5 transaction fields
- add relevant nu5 fields to CompactBlock
- restore disabled V4 unit tests
- add V5 test vectors to unit tests
The reason most of the V4 transaction and block unit tests are removed
is that they used V3 transactions, which lightwalletd never sees in
production, since lightwalletd starts at Sapling activation (which has
V4 transactions). So these tests were always wrong, in a way. This
commit simplifies the parsing code by removing support for V3 (since it
was never needed). The tests need to be updated to V4, but we'll do
that in a later PR.
Also remove the initial block load (all blocks will come from the
Staging APIs), but there is still more to do (this does not even
start up correctly) but darkside.proto is correct, we believe.
- improved corruption recovery (don't back up by just 1 block at a time)
- move darksidewallet gRPCs to their own .proto file
- this force-push removes my commits for reorg testing using SetState
