This supplies a push notification on txid becoming known to the Hub.
Additionally this changes its close relative the AddressMonitorService
to use a different tag for the transaction data and the
double-spend-proof data so as to make it obvious which one is being
sent.
The API call for GetBlock has a filter-on-address functionality which is
now ported to no longer use ripe160 addresses but instead uses output-
script hashes.
This avoids problems for transactions not using p2pkh and generally is a
cleaner solution.
This also adds a unit test to test this feature.
Remove addresses of type ripe160 to be used in the API of AddresMonitor
API service. Instead use a sha256 hash of the entire output script.
This is mostly internal changes not affecting the operations much.
The usage of a ripe160 for bitcoin addresses in the API and in the
Indexer loses some info, specifically what kind of script it is.
Additionally not all types of scripts fit this mold. At best that means
its not future-proof.
This adds a method to the API in order to select from a Tx the hashed
outscript (thats singlehashed sha256) and refactor the address indexer
to use that instead of the ripe160 address.
The API enums broke a little, so I used the opportunity to break it a
lot and clean up the enums in order to make them more future-proof.
But, yeah, software from before this commit is protocol incompatible
with software after this commit.
In the address monitor service this detects specifically if a double
spend detected by the Hub is applicable for our subscriber, and if it is
then a Message will be sent to the subscriber.
This introduces a new message type DoubleSpendFound
and changes the API for the TransactionFound message while dropping the
TransactionRejected message.
where the UTXO allows you to find an output based on txid+output, the
spentoutput DB turns that around and allows you to find an input that
spends a certain output.
This also fits perfectly find into the UTXO database class, so this
creates a new dir "spent" which is filled as expected.
This adds lots of little things;
* Add GetTransaction API call
* I refactored the GetBlock API a little to reuse code.
* a new 'Version' API call for the hub
* API for the logging manager, so we can set a default
setup with just C++-APIs
* various (usability) fixes in the FloweeServiceApplication
* Binding to localhost attempts to bind to both IPv4 and v6
* Print the actual transaction hex from indexer-cli (which really
is just a testing app)
