This modifies the SeedFromDNS function to accept a string of the DNS
seeds as well as the default port instead of a concrete chaincfg.Params
to remove the tight coupling between the two packages at the API
boundary and allow callers to easily provide custom values if desired.
This updates the mining module dependencies and serves as a base for
connmgr/v1.1.0.
The updated direct dependencies in this commit are as follows:
- github.com/decred/dcrd/chaincfg@v1.5.2
The full list of updated direct dependencies since the previous
connmgr/v1.0.2 release are as follows:
- github.com/decred/dcrd/chaincfg@v1.5.2
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 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 is a port of btcd commit b26daffac9dfe496c91a859c35a8bbe33c054b61.
This commit extends the work started by roasbeef in the
previous commit to bring full cancellation of pending
connection requests. It also adds minor refactors to
channel send/receives to help cleanup potentially
lingering go routines.
The tests in the original commit were adapted to conform to dcrd's
function signatures and a few typos were fixed. The new state introduced
by the commit (ConnCanceled) was changed to be a new one at the end of
the possible states list and the ConnFailing state was renamed back to
ConnFailed. This was done to prevent having to perform a major version
bump in the connmgr module, given those states are part of the public
API.
This is a port of btcd commit 548c0f499b24e31fa18fe6a48493e01175b54fe8.
This commit adds the ability for callers to remove pending connections
via a call to the Remove() method. With this change, upstream users of
this package can use the connmgr for more elaborate connectivity needs
as they can now cancel pending connections that are no longer needed.
The test was adapted to use the new DialAddr function, given the
difference in the function signature for Dial between btcd and dcrd.
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 allows package users to use a dial function that receives the full
address structure instead of just the protocol family and address as
strings.
This is required for some use cases in ln. While in btcsuite this was
implemented by changing the function signature of the Dial config
option, this is done here as an extra config option to prevent having to
perform a major version bump in the connmgr module.
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/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 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/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/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.

* connmgr
* database
* dcrjson
* dcrutil
* gcs
* hdkeychain
* mempool

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.
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.
This commit modifies the `ConnManager` to use the `net.Add` interface
through the package instead of a plain string to represent and
manipulate addresses. This change makes the package much more general as
users of the package can possibly utilize custom implementations of the
`net.Addr` interface to establish connections.
More precisely, the `ConnReq` struct has been modified to use a net.Addr
instance explicitly, and the `DialFunc` type has also been modified to
take a `net.Addr` directly. This latter change gives functions that
adhere to the `DialFunc` type more flexibility as to exactly how the
connection is established.
Additionally, the `connmgr.Config.GetNewAddress` configuration option
now directly returns a `net.Addr. This change allows the `connmgr` to be
decoupled from all DNS queries which allows callers to preferentially
select more secure methods like performing DNS lookups over a Tor proxy.
This modifies the connection manager to provide support for accepting
inbound connections on a caller-provided set of listeners and notify the
caller via a callback.
This is only the minimum work necessary to get inbound support into the
connection manager. The intention for future commits is to move more
connection-related logic such as limiting the maximum number of overall
connections and banned peer tracking into the connection manager.
This removes the type definitions for the callback functions in favor of
declaring them directly in the Config struct. This is more consistent
with the rest of the code base and is preferred since it means callers
reviewing the documentation don't have to follow another level of
indirection to figure out the signature.
This commit introduces package connmgr which contains connection
management related functionality.
The following is an overview of the features the package provides:
- Maintain fixed number of outbound connections
- Optional connect-only mode
- Retry persistent connections with increasing back-off
- Source peers from DNS seeds
- Use Tor to resolve DNS
- Dynamic ban scores
- Test coverage
In addition, btcd has been refactored to make use of the new package by
extending the connection manager to work with the server to source and
maintain peer connections. The following is a broad overview of the
changes to integrate the package:
- Simplify peer state by removing pending, retry peers
- Refactor to remove retries which are now handled by connmgr
- Use callback to add addresses sourced from the DNS seed
Finally the following connection-related things have been improved as a
part of this refactor:
- Fixes 100% cpu usage when network is down
- Fixes issues with max peers
- Simplify outbound peer connections management
