Importprivkey shows address
Scratching an itch: make `importprivkey` output the corresponding address.
Without this PR, `importprivkey` shows no output. Because we're moving towards an "address-based" RPC interface, rather than "account-based", there's a gap when using `importprivkey` because there's no way to assign it to a specific account, but also no easy way to determine the address. This change fixes that wart.
Previously various user-facing strings have used inconsistent currency units "BTC",
"btc" and "bitcoins". This adds a single constant and uses it for each reference to
the currency unit.
Also adds a description of the unit for --maxtxfee, and adds the missing "amount"
field description to the (deprecated) move RPC command.
Fixes#2480 where missing map entry would cause a segfault.
`wtxHeight = mapBlockIndex[wtx.hashBlock]->nHeight;` results in undefined behaviour when the block hash is not present in the map, returning a null value which is dereferenced via `->nHeight`. This error is triggered by a zero-conf wallet transaction which has not been mined yet. As discussed in #2480, on some systems there is a segfault whilst on others there is a silent exit. This makes it difficult to write a test, but the fix has been tested empirically to confirm an exception is thrown. This PR fixes the segfault and complements #2525 which prevents a user from sending from a zaddr with minconf 0.
Add ability for node to reject tx from mempool by number of tx inputs
Implement short-term solution described in #2343 so that users can respond promptly to critical short-term problems caused by quadratic validation scaling, such as the getblocktemplate latency, block propagation latency, and mempool size inflation issues described in #2333.
Requires placing block-107134.tar.gz (containing the block, and a fake CoinsDB
containing its inputs) into the base directory of the repository. This can be
generated using qa/zcash/create_benchmark_archive.py (see the script for usage
details).
To facilitate generation of the fake CoinsDB, an additional field 'valueZat' has
been added to 'getrawtransaction' containing the integer number of zatoshis
instead of a decimal number of ZEC.
Closes#2355.
- Add height parameter to z_importkey to reduce rescan range
- Change semantics of rescan parameter, so users can explicitly force a rescan
for existing keys.
Closes#2032
- 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
