7e88f61b285e6a356ea4f6ba384858f109559985 multiprocess: Make interfaces::Chain::isTaprootActive non-const (Russell Yanofsky)
Pull request description:
`interfaces::Chain` is an abstract class, so declaring the method const would be exposing internal implementation details of subclasses to interface callers. And specifically this doesn't work because the multiprocess implementation of the `interfaces::Chain::isTaprootActive` method can't be const because IPC connection state and request state is not constant during the call.

src/node/
The src/node/
directory contains code that needs to access node state
(state in CChain
, CBlockIndex
, CCoinsView
, CTxMemPool
, and similar
classes).
Code in src/node/
is meant to be segregated from code in
src/wallet/
and src/qt/
, to ensure wallet and GUI
code changes don't interfere with node operation, to allow wallet and GUI code
to run in separate processes, and to perhaps eventually allow wallet and GUI
code to be maintained in separate source repositories.
As a rule of thumb, code in one of the src/node/
,
src/wallet/
, or src/qt/
directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited src/interfaces/
classes.
This directory is at the moment
sparsely populated. Eventually more substantial files like
src/validation.cpp
and
src/txmempool.cpp
might be moved there.
