- Add an accept test for zero amounts, and a reject test for negative
amounts
- Remove ugly hack in `settxfee` that is no longer necessary
- Do explicit zero checks in wallet RPC functions
- Don't add a check for zero amounts in `createrawtransaction` - this
could be seen as a feature
My prime gripe with JSON spirit was that monetary values still had to be
converted from and to floating point which can cause deviations (see #3759
and https://bitcoin.stackexchange.com/questions/22716/bitcoind-sendfrom-round-amount-error).
As UniValue stores internal values as strings, this is no longer
necessary. This avoids risky double-to-integer and integer-to-double
conversions completely, and results in more elegant code to boot.
Strict parsing functions for other numeric types.
- ParseInt64 analogous to ParseInt32, but for 64-bit values.
- ParseDouble for doubles.
- Make all three Parse* functions more strict (e.g. reject whitespace on
the inside)
Also add tests.
- implement find_value() function for UniValue
- replace all Array/Value/Object types with UniValues, remove JSON Spirit to UniValue wrapper
- remove JSON Spirit sources
Change `read_string` to fail when not the entire input has been
consumed. This avoids unexpected, even dangerous behavior (fixes#6223).
The new JSON parser adapted in #6121 also solves this problem so in
master this is a temporary fix, but should be backported to older releases.
Also adds tests for the new behavior.
If/when CTransaction::CURRENT_VERSION is incremented, this will break CChainParams and the miner tests. This fix sets the transaction version explicitly where we depend on the hash value (genesis block, proof of work checks).
Previously due to an off-by-one error the wallet ignored
nLockTime-by-height transactions that would be valid in the next block
even though they are accepted into the mempool. The transactions
wouldn't show up until confirmed, nor would they be included in the
unconfirmed balance. Similar to the mempool behavior fix in 665bdd3b,
the wallet code was calling IsFinalTx() directly without taking into
account the fact that doing so tells you if the transaction could have
been mined in the *current* block, rather than the next block.
To fix this we strip IsFinalTx() of non-consensus-critical
functionality, removing the default arguments, and add CheckFinalTx() to
check if a transaction will be final in the next block.
