Currently, transaction hash caching is provided via Block directly, but a transaction is not always part of a block and there are several cases where only the transaction needs to be dealt with without wanting to pass the entire block and transaction index around to be able to get at the cached hash. So, this commit adds a new type named Tx which is a wrapper that provides easier and more efficient manipulation of raw wire protocol transactions. It memoizes the hash for the transaction on its first access so subsequent accesses don't have to repeat the relatively expensive hashing operations. The idea is the callers can pass around pointers to these Tx types instead of raw btcwire.MsgTx pointers. For now, the Block API has not been changed, but the plan is to change it to provide access to these wrapped transactions rather than having it do the transaction hash caching directly. This is only the first part of a series of changes working towards optimizations noted in conformal/btcd#25. |

btcutil
Package btcutil provides bitcoin-specific convenience functions and types.
A comprehensive suite of tests is provided to ensure proper functionality. See
test_coverage.txt
for the gocov coverage report. Alternatively, if you are
running a POSIX OS, you can run the cov_report.sh
script for a real-time
report. Package btcutil is licensed under the liberal ISC license.
This package was developed for btcd, an alternative full-node implementation of bitcoin which is under active development by Conformal. Although it was primarily written for btcd, this package has intentionally been designed so it can be used as a standalone package for any projects needing the functionality provided.
