d511adb664[miner] omit dummy extraNonce via IPC (Sjors Provoost)bf3b5d6d06test: clarify getCoinbaseRawTx() comparison (Sjors Provoost)78df9003d6[doc] Update comments on dummy extraNonces in tests (Anthony Towns) Pull request description: This PR changes the Mining IPC interface to stop including a dummy `extraNonce` in the coinbase `scriptSig` by default, exposing only the consensus-required BIP34 height. This simplifies downstream mining software (including Stratum v2), avoids forcing clients to strip or ignore data we generate, and reduces the risk of incompatibilities if future soft forks add required commitments to the `scriptSig`. Existing behavior is preserved for RPCs, tests, regtest, and internal mining by explicitly opting in to the dummy `extraNonce` where needed (e.g. to satisfy `bad-cb-length` at low heights), so consensus rules and test coverage are unchanged. The remainder of the PR consists of small comment fixes, naming clarifications, and test cleanups to make the intent and behavior clearer. ACKs for top commit: achow101: ACKd511adb664ryanofsky: Code review ACKd511adb664. Just rebased since last review and make suggested tweaks. I'd really like to see this PR merged for the cleanups and sanity it brings to this code. Needs another reviewer though. sedited: ACKd511adb664Tree-SHA512: d41fa813eb6b5626f4f475d8abc506b29090f4a2d218f2d6824db58b5ebe2ed7c584a903b44de18ccec142bb79c257b0aba6d6da073f56175aec88df96aaaaba
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.
