there were a lot of dumb things in Ingest() that made it really slow.
Like re-hashing the tx a bunch of times. And re-saving it to the
db redundantly.
also added local bloom filters. Maybe some concurrency issues if you
generate an address just as you're getting a tx with that address but
that doesn't seem like a real problem. Cheap to rescan anyway.
So it's faster and works better.
again with keys / values within the bolttx acting weird.
it wasn't deleting utxos that had been spent by the ingested tx.
it'd do the first 30 then stop. Deferred deletion and copied the
serialized utxo. Not sure which of those fixed it. Maybe both.
all adrs can be converted on the fly and displayed both ways.
in the actual UI this shouldn't happen though.
Also utxos are sorted and signed properly. utxo selection
is still pretty low tech.
here is code to keep track of two sets of addresses -- the
regular ones and the witness ones. But maybe those should be
merged becuase it's easy for other wallets to switch between them
and send to the same 20 byte pubkey hash but wintessified.
So maybe I'll change this stuff...
It doesn't work; can ingest out of order within a block,
so if a block has gain then loss, you might read it as loss
then gains, missing the loss.
Also, tryna implement p2wpkh
seems to go a little faster but not much.
making ingest tx take a slice of txs would be faster probably.
but it seems network i/o is the limiting factor so maybe it's OK
seems to work OK. Could be sped up by local filters instead of
ingesting every tx from the block but I can do that later if
performance (mostly disk i/o) is an issue
once multiple connections are implemented, hard mode should forward
txs to blend in.
* Previously, if the call to SetUp(..) returned an error, then the test
harness would fail to stop the running bcd process, and clean up the
test directories. This would cause any subsequent tests to fail. This
commit remedies this scenario.
move methods to new files to keep things a bit organized.
add rebroadcast of unconfirmed txs after sync
mutex on OKtxid map
deal with doublespends next
add a bool to the HashAndHeight struct;
can indicate "final". When the block market final comes in,
we don't enter wait state, but instead ask for headers.
when you don't get any headers, you wont need any blocks, and that
will assert the wait state.
Allows us to remove a lot of duplicated code pertaining to wallet
setup. We also gain hooks into the wallet to trigger callbacks once the
wallet is created/opened.
Instead of creating “fake” utxos for bob, and alice. We now employ a
dedicated mining node to hand out utxos, and generate blocks with hand
picked transactions.
A major change for btcwallet adding a new RPC wallet, refactoring parts
of the wallet, and introducing new functionality has been introduced.
This commit updates lnwallet to the API changes. A future commit will
change lnwallet to use some of the new functionality such as the
notification server, etc.
Select over the quit channel in order to shutdown goroutines waiting
for funding txn confirmations. Without this we may leak goroutines
which are blocked forever if the process isn’t exiting when the walet
is signaled to shutdown.
To try uspv, do ./lnd -spv
The remote node is hardcoded in shell.go. If you aren't
running a full node on localhost, specify where to connect to.
Nearby nodes will be much faster but random testnet nodes on the
internet should also work.
