This resolves the more fundamental flake in the unit tests noted in the
prior commit.
Because multiple unit tests call rand.Seed in parallel, it's possible
they can be executed with the same unix timestamp (in seconds). If the
second call happens between generating the hash cache and checking that
the cache doesn't contain a random txn, the random transaction is in
fact a duplicate of one generated earlier since the RNG state was reset.
To remedy, we initialize rand.Seed once in the init function.
TestHashCacheAddContainsHashes flakes fairly regularly when rebasing
PR #1684 with:
txid <txid> wasn't inserted into cache but was found.
With probabilty 1/10^2 there will be no inputs on the transaction. This
reduces the entropy in the txid, and I belive is the primary cause of
the flake.
- create benchmarks to measure allocations
- add test for benchmark input
- create a low alloc parseScriptTemplate
- refactor parsing logic for a single opcode
Update the fields of GetBlockChainInfoResult to reflect the current state of
the RPC returned by other full-node implementations.
* InitialBlockDownload - Node is in Initial Block Download mode if True.
* SizeOnDisk - The estimated size of the block and undo files on disk.
The PR #1594 introduced a change that made the order of parameters
relevant, if one of them is nil. This makes it harder to be backward
compatible with the same JSON message if an existing parameter in
bitcoind was re-purposed to have a different meaning.
To allow using a custom btcd executable, we allow specifying a path to a
file. If the path is empty, the harness will fall back to compiling one
from scratch.
Adds interface for issuing a signrawtransactionwithwallet command.
Note that this does not add functionality for the btcd rpc server
itself, it simply assumes that the RPC client has this ability and gives
an API for interacting with the RPC client.
rpc: add signrawtransactionwithwallet interface
* GetBlockTemplate RPC client implementation
* Txid added to the getblocktemplate result
* Omitempty for TxID and improved comment for GetBlockTemplate 'rules' field
Summary of changes:
- Add a new const TxFlagMarker to indicate the flag prefix byte.
- Add a new TxFlag type to enumerate the flags supported by the
tx parser.
This allows us to avoid hardcoded magics, and will make it easier
to support new flags in future.
- Improve code comments.
Closes#1598.
This modifies the goclean.sh script to run tests with the
race detector enabled. It also enables code coverage, and
uploads the results to coveralls.io.
Running tests with -race and -cover flags was disabled in
6487ba1 and 6788df7 respectively, due to some limits on
time/goroutines being hit on Travis CI. Since we have
migrated to GitHub Actions, it is desirable to bring them
back.
Currently, the only way to register HD version bytes is by initializing
chaincfg.Params struct, and registering it during package init.
RegisterHDKeyID provides a way to populate custom HD version bytes,
without having to create new chaincfg.Params instances. This is useful
for library packages who want to use non-standard version bytes for
serializing extended keys, such as the ones documented in SLIP-0132.
This function is complementary to HDPrivateKeyToPublicKeyID, which is
used to lookup previously registered key IDs.
