It is sometimes useful to interface with multiple signing providers at
once. For instance when inferring a descriptor with solving information
being provided from multiple sources (see next commit).
Instead of inneficiently copying the information from one provider into
the other, introduce a new signing provider that takes a list of
pointers to existing providers.
Replaces the constructor in CScriptID that converts a ScriptHash with a
function ToScriptID that does the same. This prepares for a move of
CScriptID to avoid a circular dependency.
error is a low-level function with a sole dependency on LogPrintf, which
is defined in logging.h
The background of this commit is an ongoing effort to decouple the
libbitcoinkernel library from the ArgsManager defined in system.h.
Moving the function out of system.h allows including it from a separate
source file without including the ArgsManager definitions from system.h.
TaprootSpendData can be gotten from TaprootBuilder, however for PSBT, we
also need TaprootBuilders directly (for the outputs). So we store the
TaprootBuilder in the FlatSigningProvider and when the TaprootSpendData
is needed, we generate it on the fly using the stored builder.
This data structures stores all information necessary for spending a taproot
output (the internal key, the Merkle root, and the control blocks for every
script leaf).
It is added to signing providers, and populated by the tr() descriptor.
These types are equivalent, in data etc, so they need only their
data cast across.
Note a function is used rather than a casting
operator as CKeyID is defined at a lower level than script/standard
Moves all of the various SigningProviders out of sign.{cpp,h} and
keystore.{cpp,h}. As such, keystore.{cpp,h} is also removed.
Includes and the Makefile are updated to reflect this. Includes were largely
changed using:
git grep -l "keystore.h" | xargs sed -i -e 's;keystore.h;script/signingprovider.h;g'
