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.

New RPC methods: return an estimate of the fee (or priority) a
transaction needs to be likely to confirm in a given number of
blocks.
Mike Hearn created the first version of this method for estimating fees.
It works as follows:
For transactions that took 1 to N (I picked N=25) blocks to confirm,
keep N buckets with at most 100 entries in each recording the
fees-per-kilobyte paid by those transactions.
(separate buckets are kept for transactions that confirmed because
they are high-priority)
The buckets are filled as blocks are found, and are saved/restored
in a new fee_estiamtes.dat file in the data directory.
A few variations on Mike's initial scheme:
To estimate the fee needed for a transaction to confirm in X buckets,
all of the samples in all of the buckets are used and a median of
all of the data is used to make the estimate. For example, imagine
25 buckets each containing the full 100 entries. Those 2,500 samples
are sorted, and the estimate of the fee needed to confirm in the very
next block is the 50'th-highest-fee-entry in that sorted list; the
estimate of the fee needed to confirm in the next two blocks is the
150'th-highest-fee-entry, etc.
That algorithm has the nice property that estimates of how much fee
you need to pay to get confirmed in block N will always be greater
than or equal to the estimate for block N+1. It would clearly be wrong
to say "pay 11 uBTC and you'll get confirmed in 3 blocks, but pay
12 uBTC and it will take LONGER".
A single block will not contribute more than 10 entries to any one
bucket, so a single miner and a large block cannot overwhelm
the estimates.
Adds two new info query commands that take over information from
hodge-podge `getinfo`.
Also some new information is added:
- `getblockchaininfo`
- `chain`: (string) current chain (main, testnet3, regtest)
- `verificationprogress: (numeric) estimated verification progress
- `chainwork`
- `getnetworkinfo`
- `localaddresses`: (array) local addresses, from mapLocalHost (fixes#1734)
contrib/devtools/fix-copyright-headers.py script to be able to perform this maintenance task with ease during the rest of the year, every year. Modifications to contrib/devtools/README.md to document what fix-copyright-headers.py does.
Currently it is only possible to use `walletpassphrase` to unlock the
wallet when bitcoin is started in server mode.
Almost everything that manipulates the wallet in the RPC console
needs the wallet to be unlocked and is thus unusable without -server.
This is pretty unintuitive to me, and I'm sure it's even more confusing
to users.
Solve this with a very minimal change: by making the GUI start a
dummy RPC thread just to handle timeouts.
Split bitcoinrpc up into
- rpcserver: bitcoind RPC server
- rpcclient: bitcoin-cli RPC client
- rpcprotocol: shared common HTTP/JSON-RPC protocol code
One step towards making bitcoin-cli independent from the rest
of the code, and thus a smaller executable that doesn't have to
be linked against leveldb.
This commit only does code movement, there are no functional changes.
Based on the proposal, update the help message of rpc methods
- strings arguments are in double quotes rather than square brackets
- numeric arguments have no quotes (and no default value)
- optional parameters are surrounded by round brackets
- json arguments are strings but don't use double quotes
Added 3 sections for the details
- Arguments: lists each argument, it's type, required or not, a default, and a description
- Result: The method result, with json format if applicable, type, and a description
- Examples: examples calls using bitcoin-cli and curl for json rpc call
Problems
- maybe this is too verbose
- lines might be too long
- description are not good or complete
- examples may be too much
Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.
- fix crash with walletpassphrase by checking if RPC server is running and
give a friendly error message how to fix this (fixes#3100)
- add 3 new RPCErrorCodes RPC_SERVER_NOT_STARTED, RPC_NODE_ALREADY_ADDED
and RCP_NODE_NOT_ADDED (I checked the source to not use a number already
in use for RPC_SERVER_NOT_STARTED)
- use the new codes where needed / missing
- add missing use of RPC_INVALID_PARAMETER
New RPC "ping" command to request ping.
Implemented "pong" message handler.
New "pingtime" field in getpeerinfo, to provide results to user.
New "pingwait" field, to show pings still in flight, to better see newly lagging peers.
dumpwallet: produce a dump of all keys in a wallet, in a format
compatible with Bitcoin Wallet for Android and Multibit.
importwallet: import such a dump
This commit decouples the pMiningKey initialization and shutdown from the RPC
threads.
`getwork` and `getblocktemplate` rely on pMiningKey, and can also be ran
from the debug window in the UI even when the RPC server is not running.
Solves issue #2706.
New method in bitcoinrpc: RunLater, that uses a map of deadline
timers to run a function later.
Behavior of walletpassphrase is changed; before, calling
walletpassphrase again before the lock timeout passed
would result in: Error: Wallet is already unlocked.
You would have to call lockwallet before walletpassphrase.
Now: the last walletpassphrase with correct password
wins, and overrides any previous timeout.
Fixes issue# 1961 which was caused by spawning too many threads.
Test plan:
Start with encrypted wallet, password 'foo'
NOTE:
python -c 'import time; print("%d"%time.time())'
... will tell you current unix timestamp.
Try:
walletpassphrase foo 600
getinfo
EXPECT: unlocked_until is about 10 minutes in the future
walletpassphrase foo 1
sleep 2
sendtoaddress mun74Bvba3B1PF2YkrF4NsgcJwHXXh12LF 11
EXPECT: Error: Please enter the wallet passphrase with walletpassphrase first.
walletpassphrase foo 600
walletpassphrase foo 0
getinfo
EXPECT: wallet is locked (unlocked_until is 0)
walletpassphrase foo 10
walletpassphrase foo 600
getinfo
EXPECT: wallet is unlocked until 10 minutes in future
walletpassphrase foo 60
walletpassphrase bar 600
EXPECT: Error, incorrect passphrase
getinfo
EXPECT: wallet still scheduled to lock 60 seconds from first (successful) walletpassphrase
