This commit unfortunately changes the public API of Block which I ordinarily don't like to do, but in this case, I felt it was necessary. The blocks used throughout the database and elsewhere should be indepedent of the protocol version which is used to encode the block to wire format. Each block has its own Version field which should be the deciding factor for the serialization and deserialization of blocks. In practice, they are currently the same encoding, but that may not always be the case, and it's important the blocks are stable depending on their own version regardless of the protocol version. This makes use of the new Serialize and Deserialize functions on MsgBlock which are intended for long-term storage as opposed to wire encoding. --- block.go | 89 +++++++++++++++++++++--------------------------- block_test.go | 89 ++++++++++++++++++------------------------------ internal_test.go | 7 ++-- 3 files changed, 75 insertions(+), 110 deletions(-) diff --git a/block.go b/block.go index 5fa860b8..254ef64d 100644 --- a/block.go +++ b/block.go @@ -25,13 +25,12 @@ func (e OutOfRangeError) Error() string { } // Block defines a bitcoin block that provides easier and more efficient -// manipulation of raw wire protocol blocks.

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. --- doc.go | 7 +++++ tx.go | 89 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 96 insertions(+) create mode 100644 tx.go diff --git a/doc.go b/doc.go index 59ed9525..1640cf2d 100644 --- a/doc.go +++ b/doc.go @@ -12,6 +12,13 @@ manipulation of raw wire protocol blocks.

This change implements Address and concrete types for P2PKH and P2SH addresses with 100% test coverage. Pay-to-pubkey support will be added in the future. This API is intended to replace the old EncodeAddress/DecodeAddress functions which are now deprecated. --- addrconvs.go | 7 ++ address.go | 231 ++++++++++++++++++++++++++++++++++++ address_test.go | 295 ++++++++++++++++++++++++++++++++++++++++++++++ internal_test.go | 34 ++++++ test_coverage.txt | 24 +++- 5 files changed, 585 insertions(+), 6 deletions(-) create mode 100644 address.go create mode 100644 address_test.go diff --git a/addrconvs.go b/addrconvs.go index 6bc7f0d3..d7d52144 100644 --- a/addrconvs.go +++ b/addrconvs.go @@ -49,6 +49,8 @@ const ( // EncodeAddress takes a 20-byte raw payment address (hash160 of a pubkey) // and the Bitcoin network to create a human-readable payment address string. +// +// DEPRECATED - Use the EncodeAddress functions of the Address interface. func EncodeAddress(addrHash []byte, net btcwire.BitcoinNet) (encoded string, err error) { if len(addrHash) != ripemd160.Size { return "", ErrMalformedAddress @@ -69,6 +71,8 @@ func EncodeAddress(addrHash []byte, net btcwire.BitcoinNet) (encoded string, err // EncodeScriptHash takes a 20-byte raw script hash (hash160 of the SHA256 of the redeeming script) // and the Bitcoin network to create a human-readable payment address string. +// +// DEPRECATED - Use the EncodeAddress functions of the Address interface. func EncodeScriptHash(addrHash []byte, net btcwire.BitcoinNet) (encoded string, err error) { if len(addrHash) != ripemd160.Size { return "", ErrMalformedAddress @@ -104,6 +108,9 @@ func encodeHashWithNetId(netID byte, addrHash []byte) (encoded string, err error // DecodeAddress decodes a human-readable payment address string // returning the 20-byte decoded address, along with the Bitcoin // network for the address. +// +// DEPRECATED - Use DecodeAddr to decode a string encoded address to +// the Address interface. func DecodeAddress(addr string) (addrHash []byte, net btcwire.BitcoinNet, err error) { decoded := Base58Decode(addr) diff --git a/address.go b/address.go new file mode 100644 index 00000000..88338d6a --- /dev/null +++ b/address.go @@ -0,0 +1,231 @@ +// Copyright (c) 2013, 2014 Conformal Systems LLC. +// Use of this source code is governed by an ISC +// license that can be found in the LICENSE file. + +package btcutil + +import ( + "bytes" + "code.google.com/p/go.crypto/ripemd160" + "errors" + "github.com/conformal/btcwire" +) + +var ( + // ErrChecksumMismatch describes an error where decoding failed due + // to a bad checksum. + ErrChecksumMismatch = errors.New("checksum mismatch") + + // ErrUnknownIdentifier describes an error where decoding failed due + // to an unknown magic byte identifier. + ErrUnknownIdentifier = errors.New("unknown identifier byte") +) + +// Address is an interface type for any type of destination a transaction +// output may spend to.

This function, adapted from the cert gen code in btcd, abstracts this logic so all programs can reuse the code. Unlike the older btcd certificate generation code, this new function allows specifying additional hostnames and IPs to add to the list of addresses for which the cert is valid. --- certgen.go | 123 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 123 insertions(+) create mode 100644 certgen.go diff --git a/certgen.go b/certgen.go new file mode 100644 index 00000000..6ad14ba1 --- /dev/null +++ b/certgen.go @@ -0,0 +1,123 @@ +// Copyright (c) 2013-2014 Conformal Systems LLC. +// Use of this source code is governed by an ISC +// license that can be found in the LICENSE file. + +package btcutil + +import ( + "bytes" + "crypto/ecdsa" + "crypto/elliptic" + "crypto/rand" + _ "crypto/sha512" // Needed for RegisterHash in init + "crypto/x509" + "crypto/x509/pkix" + "encoding/pem" + "errors" + "fmt" + "math/big" + "net" + "os" + "time" +) + +// NewTLSCertPair returns a new PEM-encoded x.509 certificate pair +// based on a 521-bit ECDSA private key.

The prefix byte (netID) which is used to encode address is the same for both the public test and regression test networks. Previously the code was working under the assumption there was a 1-to-1 mapping of prefix byte to bitcoin network, however as noted above that assumption was not correct. This commit modifies things a bit to choose the prefix byte at address creation time instead of at encode time and internally stores the prefix byte instead of the network. It also adds a new function, IsForNet, to the Address interface which allows callers to test if an address is valid for the passed network type. The end result of this change is that callers will only need to change their checks from testing if addr.Net() is the active bitcoin network to instead using addr.IsForNet(activeNet).

This commit modifies DecodeAddress to accept and decode pay-to-pubkey addresses (raw serialized public keys). Since the resulting Address needs to have a network associated with it, and a raw serialized public key does not encode the network with it, a new parameter has been added which requires the caller to specify a default network to use when decoding addresses. In the case the address has a network encoded with it such as for pay-to-pubkey-hash and pay-to-script-hash addresses, the network will be decoded from the address and the resulting Address instance will have that network associated with it. When the address does NOT have a network encoded with it, such as a pay-to-pubkey address, the provided default network will be associated with the returned Address instance. Also, the tests have been updated to test the new functionality. ok @owainga and @jrick. --- address.go | 17 +++- address_test.go | 228 +++++++++++++++++++++++----------------------- test_coverage.txt | 55 +++++------ 3 files changed, 156 insertions(+), 144 deletions(-) diff --git a/address.go b/address.go index f4104680..bb4d891c 100644 --- a/address.go +++ b/address.go @@ -118,10 +118,23 @@ type Address interface { // DecodeAddress decodes the string encoding of an address and returns // the Address if addr is a valid encoding for a known address type. -func DecodeAddress(addr string) (Address, error) { -

-0400 Subject: [PATCH 054/207] Added CoinSelector interface and a few simple algos as a sub-package This commit contains a basic definition for CoinSelector along with some utility classes and some basic algos to make creating transactions from a set of available unspent outpoints easier. Thanks to @dajohi, @davec, @jrick for all the feedback and suggestions regarding interfaces, organization, optimization, comments and documentation. --- coinset/README.md | 96 ++++++++++ coinset/coins.go | 394 ++++++++++++++++++++++++++++++++++++++ coinset/coins_test.go | 252 ++++++++++++++++++++++++ coinset/cov_report.sh | 17 ++ coinset/test_coverage.txt | 31 +++ test_coverage.txt | 44 ++--- 6 files changed, 812 insertions(+), 22 deletions(-) create mode 100644 coinset/README.md create mode 100644 coinset/coins.go create mode 100644 coinset/coins_test.go create mode 100644 coinset/cov_report.sh create mode 100644 coinset/test_coverage.txt diff --git a/coinset/README.md b/coinset/README.md new file mode 100644 index 00000000..4dc1d86a --- /dev/null +++ b/coinset/README.md @@ -0,0 +1,96 @@ +coinset +======= + +Package coinset provides bitcoin-specific convenience functions for selecting +from and managing sets of unspent transaction outpoints (UTXOs). + +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 coinset is licensed under the liberal ISC license. + +## Documentation + +Full `go doc` style documentation for the project can be viewed online without +installing this package by using the GoDoc site here: +http://godoc.org/github.com/conformal/btcutil/coinset + +You can also view the documentation locally once the package is installed with +the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to +http://localhost:6060/pkg/github.com/conformal/btcutil/coinset + +## Installation + +```bash +$ go get github.com/conformal/btcutil/coinset +``` + +## Usage + +Each unspent transaction outpoint is represented by the Coin interface. An +example of a concrete type that implements Coin is coinset.SimpleCoin. + +The typical use case for this library is for creating raw bitcoin transactions +given a set of Coins that may be spent by the user, for example as below: + +```Go +var unspentCoins = []coinset.Coin{ ... } +``` + +When the user needs to spend a certain amount, they will need to select a +subset of these coins which contain at least that value. CoinSelector is +an interface that represents types that implement coin selection algos, +subject to various criteria. There are a few examples of CoinSelector's: + +- MinIndexCoinSelector + +- MinNumberCoinSelector + +- MaxValueAgeCoinSelector + +- MinPriorityCoinSelector + +For example, if the user wishes to maximize the probability that their +transaction is mined quickly, they could use the MaxValueAgeCoinSelector to +select high priority coins, then also attach a relatively high fee. + +```Go +selector := &coinset.MaxValueAgeCoinSelector{ + MaxInputs: 10, + MinAmountChange: 10000, +} +selectedCoins, err := selector.CoinSelect(targetAmount + bigFee, unspentCoins) +if err != nil { + return err +} +msgTx := coinset.NewMsgTxWithInputCoins(selectedCoins) +... + +``` + +The user can then create the msgTx.TxOut's as required, then sign the +transaction and transmit it to the network. + +## 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: + ```bash + 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: + ```bash + git tag -v TAG_NAME + ``` + +## License + +Package coinset is licensed under the liberal ISC License. diff --git a/coinset/coins.go b/coinset/coins.go new file mode 100644 index 00000000..e65fce2e --- /dev/null +++ b/coinset/coins.go @@ -0,0 +1,394 @@ +package coinset + +import ( + "container/list" + "errors" + "github.com/conformal/btcutil" + "github.com/conformal/btcwire" + "sort" +) + +// Coin represents a spendable transaction outpoint +type Coin interface { + Hash() *btcwire.ShaHash + Index() uint32 + Value() int64 + PkScript() []byte + NumConfs() int64 + ValueAge() int64 +} + +// Coins represents a set of Coins +type Coins interface { + Coins() []Coin +} + +// CoinSet is a utility struct for the modifications of a set of +// Coins that implements the Coins interface.

-0500 Subject: [PATCH 057/207] Remove deprecated TxShas func from btcutil.Block. This commit removes the previously deprecated TxShas function from btcutil.Block. The preferred method to access transaction hashes is via the Sha function on each btcutil.Tx contained within the block. For example, the following illustrates how convert the old TxShas approach to the new method: OLD: for i, sha := range block.TxShas() { // use sha } NEW: for i, tx := range block.Transactions() { // use tx.Sha() } This commit also updates the tests for the removed function. --- block.go | 50 +++++---------------------------------- block_test.go | 60 ----------------------------------------------- test_coverage.txt | 43 +++++++++++++++++---------------- 3 files changed, 27 insertions(+), 126 deletions(-) diff --git a/block.go b/block.go index f62d9b8f..13e10d52 100644 --- a/block.go +++ b/block.go @@ -29,14 +29,12 @@ func (e OutOfRangeError) Error() string { // transactions on their first access so subsequent accesses don't have to // repeat the relatively expensive hashing operations. type Block struct { - msgBlock *btcwire.MsgBlock // Underlying MsgBlock - serializedBlock []byte // Serialized bytes for the block - blockSha *btcwire.ShaHash // Cached block hash - blockHeight int64 // Height in the main block chain - txShas []*btcwire.ShaHash // Cached transaction hashes - txShasGenerated bool // ALL transaction hashes generated - transactions []*Tx // Transactions - txnsGenerated bool // ALL wrapped transactions generated + msgBlock *btcwire.MsgBlock // Underlying MsgBlock + serializedBlock []byte // Serialized bytes for the block + blockSha *btcwire.ShaHash // Cached block hash + blockHeight int64 // Height in the main block chain + transactions []*Tx // Transactions + txnsGenerated bool // ALL wrapped transactions generated } // MsgBlock returns the underlying btcwire.MsgBlock for the Block. @@ -167,42 +165,6 @@ func (b *Block) TxSha(txNum int) (*btcwire.ShaHash, error) { return tx.Sha(), nil } -// TxShas returns a slice of hashes for all transactions in the Block.

From: Josh Rickmar Date: Fri, 11 Apr 2014 23:23:27 -0500 Subject: [PATCH 064/207] Rename AmountUnit constants. Besides being shorter, using "BTC" rather than "Bitcoin" in the AmountUnit constants is deemed to be better for these units as BTC is already a recognized monetary unit. AmountBaseBitcoin has likewise been renamed to AmountSatoshi as this is consistant with how it is returned as a string. The "standard" part of the comment in the const block has been removed, as Satoshi is technically not a standard term for this unit. ok @davecgh --- amount.go | 34 +++++++++++++++++----------------- amount_test.go | 14 +++++++------- 2 files changed, 24 insertions(+), 24 deletions(-) diff --git a/amount.go b/amount.go index 1a97941f..f3fba8aa 100644 --- a/amount.go +++ b/amount.go @@ -16,15 +16,15 @@ import ( // an amount in bitcoin to an amount counted in units. type AmountUnit int -// These constants define the various standard units used when describing -// a bitcoin monetary amount. +// These constants define various units used when describing a bitcoin +// monetary amount. const ( - AmountMegaBitcoin AmountUnit = 6 - AmountKiloBitcoin AmountUnit = 3 - AmountBitcoin AmountUnit = 0 - AmountMilliBitcoin AmountUnit = -3 - AmountMicroBitcoin AmountUnit = -6 - AmountBaseBitcoin AmountUnit = -8 + AmountMegaBTC AmountUnit = 6 + AmountKiloBTC AmountUnit = 3 + AmountBTC AmountUnit = 0 + AmountMilliBTC AmountUnit = -3 + AmountMicroBTC AmountUnit = -6 + AmountSatoshi AmountUnit = -8 ) // String returns the unit as a string.

This change removes all occurances of btcwire.BitcoinNet from exported APIs, replacing each with *btcnet.Params. This simplifies the logic for verifying string encodings of addresses and WIF private keys which use leading identifier numbers to differentiate between address types and the network they are intended for. It also allows the use of this package for non-standard networks (not mainnet, regtest, or testnet3) and future proofs it for the possible addition of future testnet networks. To update across this change, replace each btcwire.BitcoinNet parameter with the associated *btcnet.Params. For the standard networks, these changes are: btcwire.MainNet -> &btcnet.MainNetParams btcwire.TestNet -> &btcnet.RegressionNetParams btcwire.TestNet3 -> &btcnet.TestNet3Params ok @davecgh --- address.go | 281 +++++++++++++--------------------------------- address_test.go | 134 ++++++++++------------ internal_test.go | 2 +- test_coverage.txt | 63 ++++++----- wif.go | 58 +++------- wif_test.go | 6 +- 6 files changed, 183 insertions(+), 361 deletions(-) diff --git a/address.go b/address.go index 8bef8b71..295d5656 100644 --- a/address.go +++ b/address.go @@ -10,78 +10,43 @@ import ( "encoding/hex" "errors" "github.com/conformal/btcec" + "github.com/conformal/btcnet" "github.com/conformal/btcwire" ) var ( - // ErrUnknownNet describes an error where the Bitcoin network is - // not recognized. - ErrUnknownNet = errors.New("unrecognized bitcoin network") - - // ErrMalformedAddress describes an error where an address is improperly - // formatted, either due to an incorrect length of the hashed pubkey or - // a non-matching checksum. - ErrMalformedAddress = errors.New("malformed address") - // ErrChecksumMismatch describes an error where decoding failed due // to a bad checksum.

Each extended key can either be a private or public extended key +which itself is capable of deriving a child extended key. + +Determining the Extended Key Type + +Whether an extended key is a private or public extended key can be determined +with the IsPrivate function. + +Transaction Signing Keys and Payment Addresses + +In order to create and sign transactions, or provide others with addresses to +send funds to, the underlying key and address material must be accessible. This +package provides the ECPubKey, ECPrivKey, and Address functions for this +purpose. + +The Master Node + +As previously mentioned, the extended keys are hierarchical meaning they are +used to form a tree. The root of that tree is called the master node and this +package provides the NewMaster function to create it from a cryptographically +random seed. The GenerateSeed function is provided as a convenient way to +create a random seed for use with the NewMaster function. + +Deriving Children + +Once you have created a tree root (or have deserialized an extended key as +discussed later), the child extended keys can be derived by using the Child +function. The Child function supports deriving both normal (non-hardened) and +hardened child extended keys. In order to derive a hardened extended key, use +the HardenedKeyStart constant + the hardened key number as the index to the +Child function. This provides the ability to cascade the keys into a tree and +hence generate the hierarchical deterministic key chains. + +Normal vs Hardened Child Extended Keys + +A private extended key can be used to derive both hardened and non-hardened +(normal) child private and public extended keys. A public extended key can only +be used to derive non-hardened child public extended keys. As enumerated in +BIP0032 "knowledge of the extended public key plus any non-hardened private key +descending from it is equivalent to knowing the extended private key (and thus +every private and public key descending from it). This means that extended +public keys must be treated more carefully than regular public keys. It is also +the reason for the existence of hardened keys, and why they are used for the +account level in the tree. This way, a leak of an account-specific (or below) +private key never risks compromising the master or other accounts." + +Neutering a Private Extended Key + +A private extended key can be converted to a new instance of the corresponding +public extended key with the Neuter function. The original extended key is not +modified. A public extended key is still capable of deriving non-hardened child +public extended keys. + +Serializing and Deserializing Extended Keys + +Extended keys are serialized and deserialized with the String and +NewKeyFromString functions. The serialized key is a Base58-encoded string which +looks like the following: + public key: xpub68Gmy5EdvgibQVfPdqkBBCHxA5htiqg55crXYuXoQRKfDBFA1WEjWgP6LHhwBZeNK1VTsfTFUHCdrfp1bgwQ9xv5ski8PX9rL2dZXvgGDnw + private key: xprv9uHRZZhk6KAJC1avXpDAp4MDc3sQKNxDiPvvkX8Br5ngLNv1TxvUxt4cV1rGL5hj6KCesnDYUhd7oWgT11eZG7XnxHrnYeSvkzY7d2bhkJ7 + +Network + +Extended keys are much like normal Bitcoin addresses in that they have version +bytes which tie them to a specific network. The SetNet and IsForNet functions +are provided to set and determinine which network an extended key is associated +with. +*/ +package hdkeychain diff --git a/hdkeychain/example_test.go b/hdkeychain/example_test.go new file mode 100644 index 00000000..44c27afc --- /dev/null +++ b/hdkeychain/example_test.go @@ -0,0 +1,182 @@ +// Copyright (c) 2014 Conformal Systems LLC. +// Use of this source code is governed by an ISC +// license that can be found in the LICENSE file. + +package hdkeychain_test + +import ( + "fmt" + + "github.com/conformal/btcnet" + "github.com/conformal/btcutil/hdkeychain" +) + +// This example demonstrates how to generate a cryptographically random seed +// then use it to create a new master node (extended key). +func ExampleNewMaster() { + // Generate a random seed at the recommended length. + seed, err := hdkeychain.GenerateSeed(hdkeychain.RecommendedSeedLen) + if err != nil { + fmt.Println(err) + return + } + + // Generate a new master node using the seed. + key, err := hdkeychain.NewMaster(seed) + if err != nil { + fmt.Println(err) + return + } + + // Show that the generated master node extended key is private. + fmt.Println("Private Extended Key?:", key.IsPrivate()) + + // Output: + // Private Extended Key?: true +} + +// This example demonstrates the default hierarchical deterministic wallet +// layout as described in BIP0032. +func Example_defaultWalletLayout() { + // The default wallet layout described in BIP0032 is: + // + // Each account is composed of two keypair chains: an internal and an + // external one.

Collins Date: Mon, 18 Aug 2014 17:53:37 -0500 Subject: [PATCH 096/207] Add new function on extended keys to zero them. This commit adds a new function named Zero on the hdkeychain.ExtendedKey which can be used to manually clear the memory used for an extended key. This is useful for enhanced security by allowing the caller to explicitly clear the memory when they're done with a key. Otherwise it might hang around in memory for a while. Once a key has been zeroed it is no longer usable. This commit also contains tests to ensure everything works as expected after a key has been zeroed. --- hdkeychain/extendedkey.go | 29 +++++++++++++ hdkeychain/extendedkey_test.go | 79 ++++++++++++++++++++++++++++++++++ 2 files changed, 108 insertions(+) diff --git a/hdkeychain/extendedkey.go b/hdkeychain/extendedkey.go index 648ee3e1..c0e3e2b7 100644 --- a/hdkeychain/extendedkey.go +++ b/hdkeychain/extendedkey.go @@ -360,6 +360,10 @@ func (k *ExtendedKey) Address(net *btcnet.Params) (*btcutil.AddressPubKeyHash, e // String returns the extended key as a human-readable base58-encoded string. func (k *ExtendedKey) String() string { + if len(k.key) == 0 { + return "zeroed extended key" + } + var childNumBytes [4]byte depthByte := byte(k.depth % 256) binary.BigEndian.PutUint32(childNumBytes[:], k.childNum) @@ -402,6 +406,31 @@ func (k *ExtendedKey) SetNet(net *btcnet.Params) { } } +// zero sets all bytes in the passed slice to zero.

This commit corrects the Zero function in hdkeychain to nil the version instead of zeroing the bytes. This is necessary because the keys are holding onto a reference into the specific version bytes for the network as provided by the btcnet package. Zeroing them causes the bytes in the btcnet package to be zeroed which then leads to issues later when trying to use them. Also, to prevent regressions, new tests have been added to exercise this scenario.

Even though the CN should be ignored if a matching SAN hostname was found, we can prevent the parse from failing by also including the hostname as the CN.

This commit converts all block height references to int32 instead of int64. The current target block production rate is 10 mins per block which means it will take roughly 40,800 years to reach the maximum height an int32 affords. Even if the target rate were lowered to one block per minute, it would still take roughly another 4,080 years to reach the maximum. In the mean time, there is no reason to use a larger type which results in higher memory usage. --- block.go | 8 ++++---- block_test.go | 2 +- 2 files changed, 5 insertions(+), 5 deletions(-) diff --git a/block.go b/block.go index bf84354e..276f800a 100644 --- a/block.go +++ b/block.go @@ -19,7 +19,7 @@ type OutOfRangeError string // BlockHeightUnknown is the value returned for a block height that is unknown. // This is typically because the block has not been inserted into the main chain // yet. -const BlockHeightUnknown = int64(-1) +const BlockHeightUnknown = int32(-1) // Error satisfies the error interface and prints human-readable errors. func (e OutOfRangeError) Error() string { @@ -34,7 +34,7 @@ type Block struct { msgBlock *wire.MsgBlock // Underlying MsgBlock serializedBlock []byte // Serialized bytes for the block blockSha *wire.ShaHash // Cached block hash - blockHeight int64 // Height in the main block chain + blockHeight int32 // Height in the main block chain transactions []*Tx // Transactions txnsGenerated bool // ALL wrapped transactions generated } @@ -184,12 +184,12 @@ func (b *Block) TxLoc() ([]wire.TxLoc, error) { // Height returns the saved height of the block in the block chain.

02:55:56 -0500 Subject: [PATCH 152/207] txsort: Convert tests, optimize, and cleanup code. - Move hex for test txns into separate files in the testdata directory - Convert tests to table-driven tests - Make comments more consistent with the rest of the codebase - Optimize the input sorting function to perform the hash equivalence check before reversing the bytes so it can be avoided in that case

This adds a new function with loud warnings which allows sorting a transaction in place by mutating it. This is more efficient for the caller if they are the ones creating the transaction and are sure it will not invalid any cache or containing structures. The Sort function which makes a copy and is therefore does not mutate the passed transaction is still available and the default method. --- txsort/txsort.go | 17 +++++++++++++++++ txsort/txsort_test.go | 10 ++++++++++ 2 files changed, 27 insertions(+) diff --git a/txsort/txsort.go b/txsort/txsort.go index b915cb5d..9a32036c 100644 --- a/txsort/txsort.go +++ b/txsort/txsort.go @@ -14,6 +14,23 @@ import ( "github.com/btcsuite/btcd/wire" ) +// InPlaceSort modifies the passed transaction inputs and outputs to be sorted +// based on BIP LI01. +// +// WARNING: This function must NOT be called with published transactions since +// it will mutate the transaction if it's not already sorted.

First, it removes the documentation section from all the README.md files and instead puts a web-based godoc badge and link at the top with the other badges. This is being done since the local godoc tool no longer ships with Go by default, so the instructions no longer work without first installing godoc. Due to this, pretty much everyone uses the web-based godoc these days anyways. Anyone who has manually installed godoc won't need instructions. Second, it makes sure the ISC license badge is at the top with the other badges and removes the textual reference in the overview section. Third, it's modifies the Installation section to Installation and Updating and adds a -u to the go get command since it works for both and thus is simpler. Finally, it replaces the badges with SVG versions from shields.io so they are consistent. --- README.md | 28 +++++++++------------------- base58/README.md | 25 +++++++------------------ bloom/README.md | 26 ++++++++------------------ coinset/README.md | 26 ++++++++------------------ hdkeychain/README.md | 26 ++++++++------------------ txsort/README.md | 15 ++------------- 6 files changed, 42 insertions(+), 104 deletions(-) diff --git a/README.md b/README.md index 145cdb61..f0faf75f 100644 --- a/README.md +++ b/README.md @@ -1,16 +1,19 @@ btcutil ======= -[![Build Status](https://travis-ci.org/btcsuite/btcutil.png?branch=master)] +[![Build Status](http://img.shields.io/travis/btcsuite/btcutil.svg)] (https://travis-ci.org/btcsuite/btcutil) [![Coverage Status] -(https://coveralls.io/repos/btcsuite/btcutil/badge.png?branch=master)] -(https://coveralls.io/r/btcsuite/btcutil?branch=master) +(http://img.shields.io/coveralls/btcsuite/btcutil.svg)] +(https://coveralls.io/r/btcsuite/btcutil?branch=master) [![ISC License] +(http://img.shields.io/badge/license-ISC-blue.svg)](http://copyfree.org) +[![GoDoc](http://img.shields.io/badge/godoc-reference-blue.svg)] +(http://godoc.org/github.com/btcsuite/btcutil) Package btcutil provides bitcoin-specific convenience functions and types.

This corrects an issue with the serialization of extended private keys where certain underlying derivations could cause lead to printing extended privkeys that did not have the expected xprv prefix. In addition, tests for private key derivation have been added as well as a specific test which triggers the previously failing case. --- hdkeychain/extendedkey.go | 12 +++-

Mon Sep 17 00:00:00 2001 From: Dave Collins Date: Tue, 9 Feb 2016 17:29:24 -0600 Subject: [PATCH 159/207] hdkeychain: Correct extended privkey serialization. This corrects an issue with the serialization of extended private keys where certain underlying derivations could cause lead to printing extended privkeys that did not have the expected xprv prefix. In addition, tests for private key derivation have been added as well as a specific test which triggers the previously failing case. --- hdkeychain/extendedkey.go | 12 +++-

(#78) This updates all code in the main package and subpackages to make use of the new chainhash package since the old wire.ShaHash type and functions have been removed in favor of the abstracted package. Also, since this required API changes anyways and the hash algorithm is no longer tied specifically to SHA, all other functions throughout the code base which had "Sha" in their name have been changed to Hash so they are not incorrectly implying the hash algorithm. The following is an overview of the changes: - Update all references to wire.ShaHash to the new chainhash.Hash type - Rename the following functions and update all references: - Block.Sha -> Hash - Block.TxSha -> TxHash - Tx.Sha -> Hash - bloom.Filter.AddShaHash -> AddHash - Rename all variables that included sha in their name to include hash instead - Add license headers to coinset package files --- block.go | 39 ++++++++-------- block_test.go | 82 +++++++++++++++++----------------- bloom/example_test.go | 7 +-- bloom/filter.go | 21 ++++----- bloom/filter_test.go | 93 ++++++++++++++++++++------------------- bloom/merkleblock.go | 21 ++++----- bloom/merkleblock_test.go | 9 ++-- coinset/coins.go | 11 +++-- coinset/coins_test.go | 12 +++-- hdkeychain/extendedkey.go | 8 ++-- tx.go | 25 ++++++----- tx_test.go | 20 ++++----- txsort/txsort.go | 5 ++- txsort/txsort_test.go | 8 ++-- wif.go | 8 ++-- 15 files changed, 194 insertions(+), 175 deletions(-) diff --git a/block.go b/block.go index 276f800a..0eb78ece 100644 --- a/block.go +++ b/block.go @@ -1,4 +1,4 @@ -// Copyright (c) 2013-2014 The btcsuite developers +// Copyright (c) 2013-2016 The btcsuite developers // Use of this source code is governed by an ISC // license that can be found in the LICENSE file. @@ -9,6 +9,7 @@ import ( "fmt" "io" + "github.com/btcsuite/btcd/chaincfg/chainhash" "github.com/btcsuite/btcd/wire" ) @@ -31,12 +32,12 @@ func (e OutOfRangeError) Error() string { // transactions on their first access so subsequent accesses don't have to // repeat the relatively expensive hashing operations. type Block struct { - msgBlock *wire.MsgBlock // Underlying MsgBlock - serializedBlock []byte // Serialized bytes for the block - blockSha *wire.ShaHash // Cached block hash - blockHeight int32 // Height in the main block chain - transactions []*Tx // Transactions - txnsGenerated bool // ALL wrapped transactions generated + msgBlock *wire.MsgBlock // Underlying MsgBlock + serializedBlock []byte // Serialized bytes for the block + blockHash *chainhash.Hash // Cached block hash + blockHeight int32 // Height in the main block chain + transactions []*Tx // Transactions + txnsGenerated bool // ALL wrapped transactions generated } // MsgBlock returns the underlying wire.MsgBlock for the Block. @@ -67,19 +68,19 @@ func (b *Block) Bytes() ([]byte, error) { return serializedBlock, nil } -// Sha returns the block identifier hash for the Block.

This removes the entire coinset package since it is not used by anything and, even if something similar to it were desired, it's only related specifically to wallet functionality in terms of coin selection so therefore it really should go in the wallet repo. This is part of an overall effort to rework the layout of the dcrutil repo to remove unused code and cyclic dependencies. --- coinset/README.md | 71 ------- coinset/coins.go | 401 -------------------------------------- coinset/coins_test.go | 260 ------------------------ coinset/cov_report.sh | 17 -- coinset/test_coverage.txt | 31 --- 5 files changed, 780 deletions(-) delete mode 100644 coinset/README.md delete mode 100644 coinset/coins.go delete mode 100644 coinset/coins_test.go delete mode 100644 coinset/cov_report.sh delete mode 100644 coinset/test_coverage.txt diff --git a/coinset/README.md b/coinset/README.md deleted file mode 100644 index 74315a45..00000000 --- a/coinset/README.md +++ /dev/null @@ -1,71 +0,0 @@ -coinset -======= - -[![Build Status](http://img.shields.io/travis/decred/dcrutil.svg)](https://travis-ci.org/decred/dcrutil) -[![ISC License](http://img.shields.io/badge/license-ISC-blue.svg)](http://copyfree.org) -[![GoDoc](http://img.shields.io/badge/godoc-reference-blue.svg)](http://godoc.org/github.com/decred/dcrutil/coinset) - -Package coinset provides decred-specific convenience functions for selecting -from and managing sets of unspent transaction outpoints (UTXOs). - -A comprehensive suite of tests is provided to ensure proper functionality.
