Dave Collins 19880b177e Optimize InsertBlock with cached tx hashes.
This commit optimizes InsertBlock slightly by using the cached transaction
hashes instead of recomputing them.  Also, while here, use the
ShaHash.IsEqual function to do comparisons for consistency.

This is ongoing work towards conformal/btcd#25.

ok @drahn.

btcdb

Package btcdb provides a database interface for the bitcoin block chain and transactions. There is a test suite with a high percentage of code coverage. See test_coverage.txt for the current coverage (using gocov). Alternatively, if you are running a POSIX OS, you can run the cov_report.sh script for a real-time report. Package btcdb is licensed under the liberal ISC license.

Note that the main Db interface is not yet finalized, so it is subject to change.

Sample Use

	// Import packages.
	import (
		"github.com/conformal/btcdb"
		_ "github.com/conformal/btcdb/sqlite3"
		"github.com/conformal/btcutil"
		"github.com/conformal/btcwire"
	)

	// Create a database and schedule it to be closed on exit.
	dbName := "example.db"
	db, err := btcdb.CreateDB("sqlite", dbName)
	if err != nil {
		// Log and handle the error
	}
	defer db.Close()


	// Insert the main network genesis block.
	genesis := btcutil.NewBlock(&btcwire.GenesisBlock)
	newHeight, err := db.InsertBlock(genesis)
	if err != nil {
		// Log and handle the error
	}

TODO

  • Increase test coverage to 100%
  • Allow other database backends

GPG Verification Key

All official release tags are signed by Conformal so users can ensure the code has not been tampered with and is coming from Conformal. To verify the signature perform the following:

  • Download the public key from the Conformal website at https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt

  • Import the public key into your GPG keyring:

    gpg --import GIT-GPG-KEY-conformal.txt
    
  • Verify the release tag with the following command where TAG_NAME is a placeholder for the specific tag:

    git tag -v TAG_NAME
