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/dcrec/secp256k1@v1.0.1
- github.com/decred/dcrd/dcrjson@v1.1.0
- github.com/decred/dcrd/database@v1.0.3
- github.com/decred/dcrd/blockchain/stake@v1.1.0
- github.com/decred/dcrd/mining@v1.1.0
- github.com/decred/dcrd/certgen@v1.0.2
- github.com/decred/dcrd/connmgr@v1.0.2
- github.com/decred/dcrd/mempool@v1.1.0
In addition, it serves as a base for tagging releases of the following
module versions that have previous been bumped since the last release,
but not yet tagged:
- github.com/decred/dcrd/wire@v1.2.0
- github.com/decred/dcrd/chaincfg@v1.2.0
- github.com/decred/dcrd/dcrutil@v1.2.0
- github.com/decred/dcrd/txscript@v1.0.2
- github.com/decred/dcrd/blockchain@v1.1.0
- github.com/decred/dcrd/hdkeychain@v1.1.1
- github.com/decred/dcrd/peer@v1.1.0
- github.com/decred/dcrd/rpcclient@v1.1.0
Finally, it updates all of the dependencies for every module accordingly,
adds a few missing overrides for transitive dependencies, and tidies up
some of the go module sum files.
This modifies the ChainTips function in blockchain to return the results
using a type defined in the blockchain package itself instead of
directly returning a dcrjson type. This is preferable since nothing
else in the module depends on dcrjson and therefore allows the
dependency on the dcrjson module to be broken.
It also updates the RPC server that makes use of the function to perform
the necessary conversions.
Finally, the associated module hierarchy documentation is updated to
properly remove the no longer required dependency.
It should be noted that this is a breaking change to the API and thus
will need a v2 major version bump of the blockchain module to be
published before the changes can be externally consumed.
This adds a new function to peers which allows an inventory vector to be
queued for immediate send versus the standard trickling batched
inventory queue method while still respecting the functionality which
filters attempts to notify peers about inventory that they are already
known to have.
This adds a new parameter named UserAgentComments to the peer Config
struct so that callers may specify additional comments to add to the
user agent string.
It also updates the server to include the prelease portion of the
semantic version as a comment when creating peers.
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/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 adds a new testnet3 network with new genesis block, block one
ledger, treasury address, and network magic.
All consensus rules that were voted in by testnet2 are automatically
active on the new testnet3 without having to vote them in again.
Consequently, there are no consensus vote agendas defined for it.
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

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 modifies the peer code which deals with advertising service flags
via the net address fields of the version message as follows:
- For outgoing connections:
- Set the local netaddress services to what the local peer supports
- Set the remote netaddress services to 0 to indicate no services as
they are still unknown
- For incoming connections:
- Set the local netaddress services to what the local peer supports
- Set the remote netaddress services to the what was advertised by the
remote peer in its version message
This modifies the OnVersion callback to allow a reject message to be
returned in which case the message will be sent to the peer and the peer
will be disconnected.
This modifies the negotiation logic to ensure the callback has the
opportunity to see the message before the peer is disconnected and
improves the error handling when reading the remote version message.
It also has the side effect of ensuring the protocol version is
negotiated before sending reject messages with the exception of the
first message not being a version message since negotiation is not
possible in that case.
This is being changed because it is useful for the server to see the
message regardless in order to have the opportunity to things such as
update the address manager and reject peers that don't have desired
services.
This removes an impossible to hit duplicate version check and adds a
test to ensure the behavior is correct.
Previously, the check was necessary because the handler was a part of
the input handler loop, however, the initial negotiation logic was
refactored some time ago to be synchronous and thus it is no longer
possible to receive a second version message in the refactored code
path.
This rearranges some of the function definitions that pertain to initial
peer version negotiation and bringup so they are more consistent with
the preferred order used throughout the codebase. In particular, the
functions are defined before they're first used and generally as close
as possible to the first use when they're defined in the same file.
There are no functional changes.
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 modifies all packages within the repository to the use the Decred
fork of btclog which has been renamed to slog and updates the dependency
files accordingly.
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.
All instances of data race are related to accessing
KnownAddress elements, except for peer.go where its
related to closure.
Following are the changes:
- Add KnownAddress.mtx (sync.Mutex) and used same to
sync access points
- For peer.go, pass local copy to the closure
This contains the following upstream commits:
- ca4e9b82d6
- 9935fe5dba
- d009185a56
The merge commit modifies the protocol versions and the wire default
user agent version accordingly along with other minor changes in terms
of copyright dates and comment changes.
The btclog package has been changed to defining its own logging
interface (rather than seelog's) and provides a default implementation
for callers to use.
There are two primary advantages to the new logger implementation.
First, all log messages are created before the call returns. Compared
to seelog, this prevents data races when mutable variables are logged.
Second, the new logger does not implement any kind of artifical rate
limiting (what seelog refers to as "adaptive logging"). Log messages
are outputted as soon as possible and the application will appear to
perform much better when watching standard output.
Because log rotation is not a feature of the btclog logging
implementation, it is handled by the main package by importing a file
rotation package that provides an io.Reader interface for creating
output to a rotating file output. The rotator has been configured
with the same defaults that btcd previously used in the seelog config
(10MB file limits with maximum of 3 rolls) but now compresses newly
created roll files. Due to the high compressibility of log text, the
compressed files typically reduce to around 15-30% of the original
10MB file.
Replace assignments to individual fields of wire.NetAddress with
creating the entire object at once, as one would do if the type was
immutable.
In some places this replaces the creation of a NetAddress with a
high-precision timestamp with a call to a 'constructor' that converts
the timestamp to single second precision. For consistency, the tests
have also been changed to use single-precision timestamps.
Lastly, the number of allocations in readNetAddress have been reduced by
reading the services directly into the NetAddress instead of first into
a temporary variable.
The inability for a peer to negotiate is not something that should be a
warning which implies something is wrong. On the contrary, it is quite
expected that various peers will connect (or be connected to) that are
unable to properly negotiate for a variety of reasons. One example would
be a peer that is too old.
Also, while here take care of a few style nits.
This adds a new field to the peer struct which stores the protocol
version advertised by the remote peer and updates the StatsSnapshot to
return the advertised version instead of the negotiated version.
Older nodes previously added the IP and port information to the address
manager which proved to be unreliable as an inbound connection from a
peer didn't necessarily mean the peer itself accepted inbound
connections.
This also fixes a bug where the peer package was incorrectly sending
the peer's services as its own.
