This commit extends The darkside's stub zcashd rpc handler to handle the
verbose form of `getblock` (that returns the txids of all transactions
in the block) and the rest of the darkside code has to set the txids in
the blocks and individual transactions it returns. Since lightwalletd
doesn't yet support V5 txid calculation, we use the old one, so it's not
accurate for V5 but that doesn't matter (during darkside wallet testing,
the code under test can't detect incorrect txids).
Now "go test ./..." passes, it had broken due to the V5 transaction
(NU5) changes in #392. I didn't have time to fix the tests at the time.
Also, this fixes a few lint problems.
It's better not to have the vendor directory; it was needed before
modules worked well in Go. These days, the `go.mod` and `go.sum` files
nail down the exact versions of each dependency as well as the vendor
directory did. There are many modern Go projects, such as
docker/compose, that don't have a vendor directory.
So don't run `go vendor`, or if you do, don't git-add the files that
are downloaded.
Another advantage of removing the vendor directory is that the repo is
only 9% of its former size.
Another thing I did as part of this commit is to remove all the
`require` lines in `go.mod` and then ran `go tidy`. This repopulated the
require lines but with the latest versions. This may fix#378 but I'm
not sure (because I still see `gopkg.in/yaml.v2 v2.4.0 // indirect`
in `go.mod`.
This causes lightwalletd to discard cached blocks at the given height
and beyond. This in turn causes it to re-fetch those blocks from zcashd.
It's similar to --redownload, except that option discards all blocks
(equivalent to --sync-from-height 0, but the existing --redownload is
retained for compatibility).
This is mostly intended for testing. It's sometimes useful to force the
node to (re)sync some recent blocks, but redownloading all of them takes
around an hour.
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.
Instead of the Sleep function pointer being a standalong global
variable, move it into a new Time struct, and add a Now function
pointer, so that time.Now() can be mocked. Time.Now() isn't used yet.
This will be cleaner if we need to mock more time-related functions in
the future.
This commit is based on adityapk00 streaming mempool interface but
avoids using goroutines, which are difficult to reason about.

Add a new darksidewallet gRPC to add a utxo that can be returned by the
production GetAddressUtxos, for example:
grpcurl -plaintext -d '{"address":"t1g1HQJuwDoStGrYYLj8VhLu1J5igd8TNXV","txid":"1zjB42Z7FtwRZOBNMlTubCgx9l3dsZSqXxmWpuZXJto=","script": "dqkU8saQsCVS4mNwcByoGCtfOaHFaCiIrA==","valueZat": "3010000","height": "686773"}' localhost:9067 cash.z.wallet.sdk.rpc.DarksideStreamer/AddAddressUtxo
Then the following returns this entry:
grpcurl -plaintext -d '{"startHeight":0,"maxEntries":2,"addresses":["t1g1HQJuwDoStGrYYLj8VhLu1J5igd8TNXV"]}' localhost:9067 cash.z.wallet.sdk.rpc.CompactTxStreamer/GetAddressUtxos
You can also clear the list of entries:
grpcurl -plaintext localhost:9067 cash.z.wallet.sdk.rpc.DarksideStreamer/ClearAddressUtxo
testtools/genblocks/main.go:91:74: conversion from int to string yields a string of one rune, not a string of digits (did you mean fmt.Sprint(x)?)
