RPCs in blockchain.cpp were returning misleading or incorrect error
codes (for example getblock() returning RPC_INTERNAL_ERROR when the
block had been pruned). This commit fixes those error codes:
- RPC_INTERNAL_ERROR should not be returned for application-level
errors, only for genuine internal errors such as corrupted data.
- RPC_METHOD_NOT_FOUND should not be returned in response to a
JSON request for an existing method.
Those error codes have been replaced with RPC_MISC_ERROR or
RPC_INVALID_PARAMETER as appropriate.
The bumpfee() RPC was returning misleading or incorrect error codes
(for example RPC_INVALID_ADDRESS_OR_KEY when the transaction was not
BIP125 replacable). This commit fixes those error codes:
- RPC_INVALID_ADDRESS_OR_KEY if an invalid address was provided:
- Invalid change address given
- RPC_INVALID_PARAMETER if a single (non-address/key) parameter is incorrect
- confTarget and totalFee options should not both be set.
- Invalid confTarget
- Insufficient totalFee (cannot be less than required fee)
- RPC_WALLET_ERROR for any other error
- Transaction has descendants in the wallet
- Transaction has descendants in the mempool
- Transaction has been mined, or is conflicted with a mined transaction
- Transaction is not BIP 125 replaceable
- Transaction has already been bumped
- Transaction contains inputs that don't belong to the wallet
- Transaction has multiple change outputs
- Transaction does not have a change output
- Fee is higher than maxTxFee
- New fee rate is less than the minimum fee rate
- Change output is too small.
This commit also updates the test cases to explicitly test the error code.
This a breaking API change to the prioritisetransaction RPC call which previously required exactly three arguments and now requires exactly two (hash and feeDelta). The function prioritiseTransaction is also updated.
Remove -limitfreerelay and always enforce minRelayTxFee in the mempool (except from disconnected blocks)
Remove -relaypriority, the option was only used for the ability to allow free transactions to be relayed regardless of their priority. Both notions no longer apply.
Send payments during the test from a different node than the node generating
keys to be imported, so the spending node doesn't create transactions that
inadvertently involve (spend funds from) the imported keys.
Fixes#9826
This commit fixes the module-level docstrings for the tests and helper
modules in qa. Many of these tests were uncommented previously - this
commit ensures that every test case has at least a minimum level of
commenting.
Get rid of partial functions so the test can be more easily extended to add
more variants of imports with options that affect rescanning (e.g. different
key timestamps).
Also change the second half of the test to send /to/ the imported addresses,
instead of /from/ the imported addresses. The goal of this part of the test was
to confirm that the wallet would pick up new transactions after an import
regardless of whether or not a rescan happened during the import. But because
the wallet can only do this reliably for incoming transactions and not outgoing
transactions (which require the wallet to look up transaction inputs) the test
previously was less meaningful than it should have been.
Fixes a bug in AcceptBlock() in invoking CheckBlock() with incorrect
arguments, and restores a call to CheckBlock() from ProcessNewBlock()
as belt-and-suspenders.
Updates the (overspecified) tests to match behavior.
This is certainly not exhaustive, but it's better than nothing. Adds checks
for:
- Any message received before sending a version
- Any message received other than version/reject before sending a verack
It also tries to goad the remote into sending a pong, address, or block
announcement.
When importing a watch-only address over importmulti with a specific timestamp,
the wallet's nTimeFirstKey is currently set to 1. After this change, the
provided timestamp will be used and stored as metadata associated with
watch-only key. This can improve wallet performance because it can avoid the
need to scan the entire blockchain for watch only addresses when timestamps are
provided.
Also adds timestamp to validateaddress return value (needed for tests).
Fixes#9034.
Additionally, accept a "now" timestamp, to allow avoiding rescans for keys
which are known never to have been used.
Note that the behavior when "now" is specified is slightly different than the
previous behavior when no timestamp was specified at all. Previously, when no
timestamp was specified, it would avoid rescanning during the importmulti call,
but set the key's nCreateTime value to 1, which would not prevent future block
reads in later ScanForWalletTransactions calls. With this change, passing a
"now" timestamp will set the key's nCreateTime to the current block time
instead of 1.
Fixes#9491
Make sure that RPC tests are actually checking failures correctly by:
- Catching JSON RPC exceptions and verifying the error codes and messages.
- Failing the test case if the JSON RPC exception isn't raised.
A few miscellaneous improvements to rpc-tests.py command line arguments:
- make all arguments start with double dash for consistency
- improve help text and output
- add nozmq argument to explicitly exclude the ZMQ tests
- change 'parallel' to 'jobs'
Preserve comment, order form, and account strings from the original wallet
transaction. Also set fTimeReceivedIsTxTime and fFromMe fields for consistency
with CWallet::CreateTransaction. The latter two fields don't influence current
wallet behavior, but do record that the transaction originated in the wallet
instead of coming from the network or sendrawtransaction.
