This change fixes the suite names all around the test files, to make them match to the folder name in which this test files are located. Also, the RCL test files are relocated to the consensus folder, because they are testing consensus functionality.
Fixes issue #4937.
The fixReducedOffersV1 amendment fixed certain forms of offer
modification that could lead to blocked order books. Reduced
offers can block order books if the effective quality of the
reduced offer is worse than the quality of the original offer
(from the perspective of the taker). It turns out that, for
small values, the quality of the reduced offer can be
significantly affected by the rounding mode used during
scaling computations.
Issue #4937 identified an additional code path that modified
offers in a way that could lead to blocked order books. This
commit changes the rounding in that newly located code path so
the quality of the modified offer is never worse than the
quality of the offer as it was originally placed.
It is possible that additional ways of producing blocking
offers will come to light. Therefore there may be a future
need for a V3 amendment.
Curtail the occurrence of order books that are blocked by reduced offers
with the implementation of the fixReducedOffersV1 amendment.
This commit identifies three ways in which offers can be reduced:
1. A new offer can be partially crossed by existing offers, so the new
offer is reduced when placed in the ledger.
2. An in-ledger offer can be partially crossed by a new offer in a
transaction. So the in-ledger offer is reduced by the new offer.
3. An in-ledger offer may be under-funded. In this case the in-ledger
offer is scaled down to match the available funds.
Reduced offers can block order books if the effective quality of the
reduced offer is worse than the quality of the original offer (from the
perspective of the taker). It turns out that, for small values, the
quality of the reduced offer can be significantly affected by the
rounding mode used during scaling computations.
This commit adjusts some rounding modes so that the quality of a reduced
offer is always at least as good (from the taker's perspective) as the
original offer.
The amendment is titled fixReducedOffersV1 because additional ways of
producing reduced offers may come to light. Therefore, there may be a
future need for a V2 amendment.
