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.
This commit modifies the code to no longer require a protocol version. It
does this by making use of the new Serialize function in btcwire.
Unfortuantely this does entail a public API change which I generally don't
like to do, but eliminating the usage of the protocol version throughout
the codebase was important enough to warrant the change.
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
We do this by allowing the parser to return the list of parsed objects
(it is an internal only api anyway) and then we use this in the sigops
counting and ignore the error. This change due to bitcoind
compatability.
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).
btcscript contains an amount of debug logging that is very useful to
have. We have agreed that testing this isn't realy practical or indeed
really useful and thus is rather unlikely to grow test coverage any time
soon.
To be usd for validation. Most of the codepaths teste, a few tests
missing for cases needed tests in the validation codepaths too. To be
worked on in tree.
The only time we need to zero out scripts is for calcScriptHash which operates
on a deep copy anyway. This should make the tx passed to us unmodified now.
We were counting the number of push ops instead of the number of non
push ops. Add tests that found this (checking tha the max operations
check fires).
Use this to test the pubkey paths in checksig which return btcec errors
which we don't define. all of the other active tests know the return
code we need.
