This updates the main module to use the latest available minor and patch
versions of all modules and reverts the recent change that incorrectly
removed all of the blake256 references from the various go.sum files.
The following required direct dependencies are bumped as follows:
- github.com/decred/dcrd/blockchain/stake@v1.2.1
- github.com/decred/dcrd/blockchain/stake/v2@v2.0.1
- github.com/decred/dcrd/certgen@v1.1.0
- github.com/decred/dcrd/chaincfg@v1.5.2
- github.com/decred/dcrd/chaincfg/chainhash@v1.0.2
- github.com/decred/dcrd/chaincfg/v2@v2.2.0
- github.com/decred/dcrd/dcrutil/v2@v2.0.0
- github.com/decred/dcrd/gcs@v1.1.0
- github.com/decred/dcrd/hdkeychain/v2@v2.0.1
- github.com/decred/dcrd/txscript/v2@v2.0.0
- github.com/decred/dcrwallet/rpc/jsonrpc/types@v1.2.0
This updates the code to make use of the new crypto/blake256 module instead of
github.com/dchest/blake256.
* change the references in the chaincfg/chainhash and gcs modules
* update chaincfg/chainhash to use the new Sum256 API
* remove references to dchest/blake256 from all go.sum files
This updates the gcs dependencies and serves as a base for gcs/v1.1.0.
The updated direct dependencies in this commit are as follows:
- github.com/decred/dcrd/blockchain/stake/v2@v2.0.0
The full list of updated direct dependencies since the previous
gcs/v1.0.2 release are as follows:
- github.com/decred/dcrd/blockchain/stake/v2@v2.0.0
- github.com/dchest/siphash@v1.2.1
- github.com/decred/dcrd/txscript/v2@v2.0.0
- github.com/decred/dcrd/wire@v1.2.0
This optimizes the AddSigScript method on the blockcf.Entries types by
making use of the zero-alloc tokenizer now available in the txscript/v2
module.
The following is a before and after comparison of analyzing typical
standard signature script to redeem a pay-to-pubkey-hash:
benchmark old ns/op new ns/op delta
---------------------------------------------------------
BenchmarkAddSigScript 494 374 -24.29%
benchmark old allocs new allocs delta
---------------------------------------------------------
BenchmarkAddSigScript 3 2 -33.33%
benchmark old bytes new bytes delta
---------------------------------------------------------
BenchmarkAddSigScript 128 80 -37.50%
This updates the gcs module to use v2 of the txscript module.
The updated direct dependencies are as follows:
- github.com/decred/dcrd/txscript/v2@v2.0.0
This updates all of the modules that still rely on v1 of the chaincfg
module to use v1.5.1 which builds correctly with the major API bump
introduced in the edwards v1.0.0 module.
While here, it also updates all references to the v0 edwards and dcrec
modules to their tagged v1 counterparts, tidies all of the modules via
go mod tidy, and removes all unnecessary indirect entries from the mod
files to keep the modules using the versions the dependencies are tested
with.
The primary motivation for this change is that the chaincfg/v2 module
requires edwards/v1 which is not API compatible with edwards/v0.
Consequently, in order for each module to be incrementally updated to
use chaincfg/v2, all of its dependencies must also be able to build with
edwards/v1 which is the case as of chaincfg v1.5.1.
This adds the go 1.11 directive to all of the modules in order to
clearly mark they build and work with that version. Go 1.12 modified
the tools such that tidy will automatically add the new version to
modules that do not already have a directive and that would prevent
builds on Go 1.11 through Go 1.11.3 which is not desirable.
This modifies all of the modules, with the exception of the root module,
to remove all replacement directives from their go.mod files and update
the requirements and module sums accordingly.
While it is nice to be able to build and test directly from each module
directory and have it pull in the latest untagged changes when
developing, having all of the overrides in each module makes it
infeasible to use the module tools to help maintain the modules and thus
makes it quite difficult to ensure they are all independently accurate
for external consumers.
By maintaining all of the overrides in the root module and invoking all
builds and tests from it, the overrides will apply to ensure the latest
code is being built and tested.
This also modifies the tests script used with in CI to run all of the
tests from the root module accordingly.
This bumps the various module versions as follows:
- github.com/decred/dcrd/addrmgr@v1.0.2
- github.com/decred/dcrd/wire@v1.1.0
- github.com/decred/dcrd/chaincfg@v1.1.1
- github.com/decred/dcrd/connmgr@v1.0.1
- github.com/decred/dcrd/dcrutil@v1.1.1
- github.com/decred/dcrd/database@v1.0.1
- github.com/decred/dcrd/hdkeychain@v1.1.0
- github.com/decred/dcrd/txscript@v1.0.1
- github.com/decred/dcrd/blockchain/stake@v1.0.1
- github.com/decred/dcrd/gcs@v1.0.1
- github.com/decred/dcrd/blockchain@v1.0.1
- github.com/decred/dcrd/mining@v1.0.1
- github.com/decred/dcrd/mempool@v1.0.1
- github.com/decred/dcrd/peer@v1.0.1
- github.com/decred/dcrd/rpcclient@v1.0.1
It also updates all of the dependencies for every module accordingly and
adds a few missing overrides for transitive dependencies.
This further refines the modules to add the following new modules
instead of depending on the entire dcrd module:
- github.com/decred/dcrd/dcrjson@v1.0.0
- github.com/decred/dcrd/blockchain@v1.0.0
- github.com/decred/dcrd/blockchain/stake@v1.0.0
- github.com/decred/dcrd/gcs@v1.0.0
- github.com/decred/dcrd/mining@v1.0.0
- github.com/decred/dcrd/mempool@v1.0.0
- github.com/decred/dcrd/peer@v1.0.0
- github.com/decred/dcrd/rpcclient@v1.0.0
Also, it ensures modules that rely on other modules within the repo are
provided replacements to the latest repo code to ensure builds against
master and continuous integration use the latest code.
- github.com/decred/dcrd/addrmgr
- github.com/decred/dcrd/blockchain
- github.com/decred/dcrd/blockchain/stake
- github.com/decred/dcrd/chaincfg
- github.com/decred/dcrd/connmgr
- github.com/decred/dcrd/database
- github.com/decred/dcrd/dcrec/secp256k1
- github.com/decred/dcrd/dcrjson
- github.com/decred/dcrd/dcrutil
- github.com/decred/dcrd/gcs
- github.com/decred/dcrd/hdkeychain
- github.com/decred/dcrd/mempool

- github.com/decred/dcrd/peer
- github.com/decred/dcrd/rpcclient
- github.com/decred/dcrd/txscript
- github.com/decred/dcrd/wire
This removes a bunch of build modules that rely on a version of dcrd
that doesn't exist and updates the root module so dcrd can be built with
the upcoming go1.11 release.
This adds module support for the versioned go toolchain. In particular,
the following packages are defined as modules:
* addrmgr
* blockchain
* certgen
* chaincfg
* connmgr
* database
* dcrjson
* dcrutil
* gcs
* hdkeychain
* mempool
* mining
* peer
* rpcclient
* txscript
* wire
It does not update the travis build environment or README since it is
experimental at this point.
This change begins the work of bringing committed filters to the
network consensus daemon. Committed filters are designed to enable
light wallets without many of the privacy issues associated with
server-side bloom filtering.
The new gcs package provides the primitives for creating and matching
against Golomb-coded sets (GCS) filters while the blockcf package
provides creation of filters and filter entries for data structures
found in blocks.
The wire package has been updated to define a new protocol version and
service flag for advertising CF support and includes types for the
following new messages: cfheaders, cfilter, cftypes, getcfheaders,
getcfilter, getcftypes. The peer package and server implementation
have been updated to include support for the new protocol version and
messages.
Filters are created using a collision probability of 2^-20 and are
saved to a new optional database index when running with committed
filter support enabled (the default). At first startup, if support is
not disabled, the index will be created and populated with filters and
filter headers for all preexisting blocks, and new filters will be
recorded for processed blocks.
Multiple filter types are supported. The regular filter commits to
output scripts and previous outpoints that any non-voting wallet will
require access to. Scripts and previous outpoints that can only be
spent by votes and revocations are not committed to the filter. The
extended filter is a supplementary filter which commits to all
transaction hashes and script data pushes from the input scripts of
non-coinbase regular and ticket purchase transactions. Creating these
filters is based on the algorithm defined by BIP0158 but is modified
to only commit "regular" data in stake transactions to prevent
committed filters from being used to create SPV voting wallets.
