This commit implents a basic infrastructure to be used throughout the
tests for creating a new chain instance that is ready to have tests run
against it. It also returns a teardown function the caller can use to
clean up after it is done testing. This paves the way for adding more
tests.
The stack data is normally sliced from the actual script and btcscript is not
supposed to ever change the tx passed into it.
Add a test (and fix the other leading zeros tests) to stop this happening again.
The block manager handles inventory messges to know which inventory should
be requested based on what is already known and what is already in flight.
So, this commit adds logic to ask the transaction memory pool if the
transaction is already known before requesting it and tracks pending
requests into an in-flight transaction map owned by the block manager.
It also moves the transaction processing into the block manager so the
in-flight map can be properly cleaned.
This commit changes the InvVect_* constants, which are not standard Go
style, to the InvType*. In order to preserve backwards compatibility, it
also adds a legacy.go file which maps the old public constant names to the
new ones.
Closes#1.
The original thought was that chain would also house the transaction
memory pool, but that ultimately was decided against. As a result,
it only makes sense to query chain for blocks rather than generic
inventory.
So add entries for them that disassemble and parse ok, but will fail
when executed with the appropriate error. Add a full suite of tests to confirm
that this happens.
Found by a strange transaction in testnet.
Also, the loops which only remove a single element and break or return
don't need the extra logic for iteration since they don't continue
iteration after removal.
It is not safe to remove an item from a container/list while iterating the
list without first saving the next pointer since removing the item nils
the internal list element's next pointer.
It is technically possible for the Read method on a reader to return zero
bytes read with a nil error even though that behavior is "discouraged" by
the interface documenation. This commit switches the read of the first
byte to use io.ReadFull which will always error in this case.
This commit corrects the reading of the serialized height in coinbase
transactions for block height of version 2 or greater. On mainnet, the
serialized height is always 3 bytes and will continue to be so for
something like another ~159 years, so there was no issue with mainnet.
However on testnet, there are some version 2 blocks which are low enough
in the chain to only take 2 bytes to serialize.
In addition, this commit adds a full tests for the relavant function
including negative tests and variable length serialized lengths for block
heights.
Closes#1.
btcdb was changed a while back to not insert the genesis block by default.
This commit modifies the reorg test to insert it as required so not all
blocks are orphans.
Rather than showing all errors from ProcessTransaction as a failure, check
if the error is a TxRuleError meaning the transaction was rejected as
opposed to something actually going wrong and log it accordingly.
Rather than showing all errors from ProcessBlock as a failure, check if
the error is a RuleError meaning the block was rejected as opposed to
something actually going wrong and log it accordingly.
