"Block difficulty" is the difficulty listed in a block's header, which in the
testnet can sometimes be min-difficulty (if time-since-last-block is too large).
"Network difficulty" is the difficulty that the network was trying to satisfy
at a particular block height. In mainnet this is always equal to the difficulty
of the solved block for that height, but in testnet the network difficulty is
derived from the last non-min-difficulty block difficulty.
This commit fixes the RPC APIs that are intended to show network difficulty, so
that on testnet they don't sometimes drop to 1.0, confusing users.
Closes#1181
Some specifics on consensus changes:
* Transactions must be anchored to a real anchor in the chain.
* Anchors are pushed and popped during ConnectBlock/DisconnectBlock as appropriate.
* DisconnectTip triggers evictions, under some circumstances, of transactions in the
mempool which are anchored to roots that are no longer valid.
* Commitments append to the tree at the current best root during ConnectBlock.
has parts of @mhearn #4351
* allows querying the utxos over REST
* same binary input and outputs as mentioned in Bip64
* input format = output format
* various rpc/rest regtests
Adds a regression test for the wallet's ResendWalletTransactions function, which uses a new, hidden RPC command "resendwallettransactions."
I refactored main's Broadcast signal so it is passed the best-block time, which let me remove a global variable shared between main.cpp and the wallet (nTimeBestReceived).
I also manually tested the "rebroadcast unconfirmed every half hour or so" functionality by:
1. Running bitcoind -connect=0.0.0.0:8333
2. Creating a couple of send-to-self transactions
3. Connect to a peer using -addnode
4. Waited a while, monitoring debug.log, until I see:
```2015-03-23 18:48:10 ResendWalletTransactions: rebroadcast 2 unconfirmed transactions```
One last change: don't bother putting ResendWalletTransactions messages in debug.log unless unconfirmed transactions were actually rebroadcast.
Rebased by @laanwj:
- update for RPC methods added since 84d13ee: setmocktime,
invalidateblock, reconsiderblock. Only the first, setmocktime, required a change,
the other two are thread safe.
3c30f27 travis: disable rpc tests for windows until they're not so flaky (Cory Fields)
daf03e7 RPC tests: create initial chain with specific timestamps (Gavin Andresen)
a8b2ce5 regression test only setmocktime RPC call (Gavin Andresen)
Start the RPC server before doing all the (expensive) startup
initialisations like loading the block index. Until the node is ready,
return all calls immediately with a new error signalling "in warmup"
with an appropriate status message (similar to the init message).
This is useful for RPC clients to know that the server is there (e. g.,
they don't have to start it) but not yet available. It is used in
Namecoin and Huntercoin already for some time, and there exists a UI
hooked onto the RPC interface that actively uses this to its advantage.
- ensures a consistent usage in header files
- also add a blank line after the copyright header where missing
- also remove orphan new-lines at the end of some files
Port over https://github.com/chronokings/huntercoin/pull/19 from
Huntercoin: This implements a new RPC command "getchaintips" that can be
used to find all currently active chain heads. This is similar to the
-printblocktree startup option, but it can be used without restarting
just via the RPC interface on a running daemon.
Changes:
* Add Add/Have WatchOnly methods to CKeyStore, and implementations
in CBasicKeyStore.
* Add similar methods to CWallet, and support entries for it in
CWalletDB.
* Make IsMine in script/wallet return a new enum 'isminetype',
rather than a boolean. This allows distinguishing between
spendable and unspendable coins.
* Add a field fSpendable to COutput (GetAvailableCoins' return type).
* Mark watchonly coins in listunspent as 'watchonly': true.
* Add 'watchonly' to validateaddress, suppressing script/pubkey/...
in this case.
