The idea here is that interface_test.go will be directly usable in each
implementation to increase test coverage there as well, but also works at
the top-most level to test arbitrary backends.
This is simply at start at providing generic interface tests. The only
thing is tests so far is the empty database conditions on NewestSha, but
it adds infrastructure for creating and opening databases with special
type handling based on the database and necessary logic to teardown so
multiple backends can be tested simultaneously.
This and the next series of commits all discussed with drahn@.
FetchTxBySha changes what it returns, it can now return a TxListReply and
and error if none are found.
FetchTxByShaList is renamed to FetchUnSpentTxByShaList to indicate that
it will (likey/eventually) only return Tx that have some unspent TxOuts.
Tx which are fully spent may not be (reliably) looked up using this API.
improved error handling
Fix testing, no point in running tests multiple times
Fix error when no blocks in database, reopen would misreport NewstSha() return
This code is still prototype at this time.
It appears to function correctly but something
consumes more memory than is considered reasonable
for the dataset comprised of the full bitcoind chain.
Not recommened for use at this time.
This commit updates the calls into btcutil and btcwire for the latest API
changes which remove the need for the protocol version for serialization
and deserialization of blocks and transactions.
Fix error returns in InsertBlock and FetchBlockBySha
Give up on return by name in InsertBlock() and return explicit
err one location in FetchBlockBySha to return proper error value
This commit modifies the way initial database creation is handled.
Previously, the genesis for the main chain was inserted automatically upon
creation of the database. However, that approach caused an issue since
other networks such as the test network don't use the same genesis block
as the main network.
The new approach introduced by this commit is to leave it up to the caller
to insert the desired genesis block. In order to support this, the
InsertBlock function has been modified to allow the first (and only the
first) block to be inserted without having an existing parent. Also, the
NewestSha function has been modified to return a zero hash, -1 for the
height, and no error when the database does not yet have any blocks. This
allows the caller to determine the difference between no blocks and only
the genesis block (in which case the return values would be the genesis
hash and 0 for the height).
