[electrum] fix signature updating in fusion code Authored by PiRK on Nov 17 2023, 15:21. Tags None Subscribers None
Details
This is a bugfix follow-up to D14472. tx.inputs() now builds the coin dicts on demand, and changing the returned coin dicts no longer affects the transaction in any way. The code needs to operate on tx.txinputs() which returns a list of references to the actual coin stored in the transaction. Check that there are no other signatures updating in coin dicts left in the codebase (except for some coin dict serialization code for legacy IO): grep -r '\["signatures"\] =' . grep -r '\["signatures"\]\[' . Patch the server code to allow for testing with two wallets: diff --git a/electrum/electrumabc_plugins/fusion/server.py b/electrum/electrumabc_plugins/fusion/server.py index 8242a2686a..ac85a86ea7 100644 --- a/electrum/electrumabc_plugins/fusion/server.py +++ b/electrum/electrumabc_plugins/fusion/server.py @@ -113,12 +113,12 @@ class Params: ] # How many clients do we want before starting a fusion? - min_clients = 8 + min_clients = 2 # If all clients submitted largest possible component (uncompressed p2pkh input), how many could we take until the result would exceed 100 kB standard tx size limitation? max_clients = (100000 - 12) // (num_components * 173) # Every round, clients leave ...
