src/miner.cpp
206 ↗	(On Diff #8224)	Why is the coinbase tx size not set?
src/miner.h
30 ↗	(On Diff #8224)	The code seems to indicate that this actually negative total fees. The comment should indicate this.
30 ↗	(On Diff #8224)	Why rename these? it will only make backports more difficult with no benefit.

src/miner.cpp
206 ↗	(On Diff #8224)	I don't know. Apparently it's not important. This change is trying to rename a variable.
src/miner.h
30 ↗	(On Diff #8224)	This code is unique to ABC. It was written to deal with CTOR sorts.
30 ↗	(On Diff #8224)	They're not negative.

src/miner.h
30 ↗	(On Diff #8224)	The code below has multiple places where txFees is negative and I can't find anywhere they are actually positive values.
30 ↗	(On Diff #8224)	ok

src/miner.h
30 ↗	(On Diff #8224)	Which code below? There is no code below that assumes these are negative. If you're talking about: pblocktemplate->entries.emplace_back(CTransactionRef(), -SATOSHI, 0, -1); That's because they're supposed to be out of bounds.

src/miner.cpp
193 ↗	(On Diff #8224)	@jasonbcox You can see right here that these fees are not negative. They are added to the subsidy to generate the coinbase vout.
361 ↗	(On Diff #8224)	@jasonbcox And they are added together here. So there's no funny business going on with the sign.

src/miner.cpp
206 ↗	(On Diff #8224)	Clearly txSize is being added in this diff, so it's absolutely applicable to review here.

src/miner.cpp
206 ↗	(On Diff #8224)	These original entries predate anything I've done, and the coinbase transaction is discarded in `getblocktemplate` with only fees being returned. The mining pool software is expected to fill in the details within the 1000 bytes of reserved space. When the `generate` rpc is called on `regtest` the IncramentExtraNonce function does use the coinbase, but these fields are also not used.
