Add DifficultyRatio to GetBlockChainInfoResult, and bump the minor rpc
version accordingly. This is to maintain consistency with GetDifficulty
RPC. Also deprecate the existing Difficuly field in
GetBlockChainInfoResult, to be removed in a future major version bump.
This modifies the getblock and getblockheader RPC results to include the
total number of hashes expected to produce the chain up to the requested
block in hex and updates the JSON-RPC API documentation accordingly.
This modifies the getblock and getblockheader RPC results to be a little
more consistent in their ordering, to include the extra data field in
the getblockheader results, and to update the JSON-RPC API documentation
for both to match reality. The documentation was missing several fields
and had some typos.
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 revamps the main README.md file in an attempt to provide a more
user-friendly introduction to the software and why someone would want to
run it and also updates the docs/README.md to remove some sections that
do not apply to Decred and update some others to reflect reality.
It also adds minimum recommended specifications for dcrd to the main
README.md and updates the build instruction for module-aware builds and
the recent changes the run_test.sh script.
Finally, it updates the contact information to point to the
decred.org/community page.
This modifies the results provided by the getrawtransaction and
searchrawtransactions RPCs to make them consistent with each other.
In particular, it adds the transaction expiry, block height, and block
index fields to the searchrawtransactions result and ensures that both
omit the block height when it is zero so that it is not included in the
results for mempool transactions.
Since populating the block index requires additional details to be
stored to the transaction index to efficiently provide, only the
infrastructure is added and the value is left as the default for now,
which means it will be omitted and therefore not change the visible
behavior.
Finally, it also updates the RPC server help to provide consistent
descriptions for the fields and also updates the JSON-RPC documentation.
This adds an amount field to TransactionInput intended for specifying the prev out amount when creating a transaction. createraw/ssrtx/sgentx/transaction rpcs are also updated accordingly as well as associated tests.
A typo in assignField is also corrected.
The 'txaccepted' method is currently showing an out of date parameter within json_rpc_api.md. The first parameter is currently set to 'TxSha', however it should be set to either 'TxID' or 'TxHash' .
This modifies the example for connecting to the dcrd RPC server from
node.js to work with node.js v8.11.1 LTS and v10.0.1 along with calling
out the tested version and requirement for the additional ecdhCurve
parameter on v8.11.1 LTS.
Bite the bullet now and remove carriage return (`\r`) from all
documentation files to allow further edits without messy diffs.
No further changes have been made besides `sed -i 's/\r//g' docs/*`.
This implements the getchaintips JSON-RPC and updates the associated
JSON-RPC API documentation accordingly.
It should be noted that until the entire block index is loaded into
memory, the chain tips tracking currently only works with tips that have
been seen since the daemon was started.
This merge commit adds the following code from the
github.com/decred/dcrutil package into a new
github.com/decred/dcrd/dcrutil package:
* Address handling
* Amount type
* AppDataDir func
* bitflags functions
* Block wrapper type
* Hash160 func
* Tx wrapper type
* WIF type
as well as all tests for this code.
The old github.com/decred/dcrutil/hdkeychain package has also been
merged and moved to github.com/decred/dcrd/dcrutil/hdkeychain.
dcrd packages have been updated to use the new packages and the dep
files have been updated for this change.
modifications to the stakebase tx vin[0] required adding a stakebase
field to Vin and VinPrevOut structs as well as updating the
rpc documentation for the affected calls.
The following updates were done throughout and were made to make important
information in the docs stand out at a glance:
- updates to requests info
- stylistic changes to displaying params
- returns and their types
The extended methods section was also removed (entries are now listed as
standard methods) since that section only applied to upstream. A doc entry for
loadtxfilter was also added.
This improves the help text for stakedifficulty field of the
getmininginfo RPC to clarify it is the value for the next block.
Also, update the JSON-RPC docs entry to include the field which should
have been done previously.
The github markdown interpreter has been changed such that it no longer
allows spaces in between the brackets and parenthesis of links and now
requires a newline in between anchors and other formatting. This
updates all of the markdown files accordingly.
While here, it also corrects a couple of inconsistencies in some of the
README.md files and correct some previous merge conflicts.
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
Contains the following commits:
- 711f33450c
- b6b1e55d1e
- Reverted because Travis is already at a more recent version
- bd4e64d1d4
Also, the merge commit contains the necessary decred-specific
alterations, converts all other references to sha to hash to keep with
the spirit of the merged commits, and various other cleanup intended to
bring the code bases more in line with one another.

This adds a full-blown testing infrastructure in order to test consensus
validation rules. It is built around the idea of dynamically generating
full blocks that target specific rules linked together to form a block
chain. In order to properly test the rules, each test instance starts
with a valid block that is then modified in the specific way needed to
test a specific rule.
Blocks which exercise following rules have been added for this initial
version. These tests were largely ported from the original Java-based
'official' block acceptance tests as well as some additional tests
available in the Core python port. It is expected that further tests
can be added over time as consensus rules change.
* Enough valid blocks to have a stable base of mature coinbases to spend
for futher tests
* Basic forking and chain reorganization
* Double spends on forks
* Too much proof-of-work coinbase (extending main chain, in block that
forces a reorg, and in a valid fork)
* Max and too many signature operations via various combinations of
OP_CHECKSIG, OP_MULTISIG, OP_CHECKSIGVERIFY, and OP_MULTISIGVERIFY
* Too many and max signature operations with offending sigop after
invalid data push
* Max and too many signature operations via pay-to-script-hash redeem
scripts
* Attempt to spend tx created on a different fork
* Attempt to spend immature coinbase (on main chain and fork)
* Max size block and block that exceeds the max size
* Children of rejected blocks are either orphans or rejected
* Coinbase script too small and too large
* Max length coinbase script
* Attempt to spend tx in blocks that failed to connect
* Valid non-coinbase tx in place of coinbase
* Block with no transactions
* Invalid proof-of-work
* Block with a timestamp too far in the future
* Invalid merkle root
* Invalid proof-of-work limit (bits header field)
* Negative proof-of-work limit (bits header field)
* Two coinbase transactions
* Duplicate transactions
* Spend from transaction that does not exist
* Timestamp exactly at and one second after the median time
* Blocks with same hash via merkle root tricks
* Spend from transaction index that is out of range
* Transaction that spends more that its inputs provide
* Transaction with same hash as an existing tx that has not been
fully spent (BIP0030)
* Non-final coinbase and non-coinbase txns
* Max size block with canonical encoding which exceeds max size with
non-canonical encoding
* Spend from transaction earlier in same block
* Spend from transaction later in same block
* Double spend transaction from earlier in same block
* Coinbase that pays more than subsidy + fees
* Coinbase that includes subsidy + fees
* Invalid opcode in dead execution path
* Reorganization of txns with OP_RETURN outputs
* Spend of an OP_RETURN output
* Transaction with multiple OP_RETURN outputs
* Large max-sized block reorganization test (disabled by default since
it takes a long time and a lot of memory to run)
Finally, the README.md files in the main and docs directories have been
updated to reflect the use of the new testing framework.
