* RC9 suggested improvements (#1005)
* Revert AuctionNotTakeable in same place, load auction kickTime only once from storage
* Calculate ERC721 collateralTaken only once
cosmetize code (read from result struct in local var and reuse)
Results in shrinking a little bit contract sizes
* Read borrower Np Tp ratio from storage only once when kick
* If block style, proper indentation
* Proposed changes to PR #972:
- avoid calculating current LUP twice in lender kick
- change _kick function to accept proposed LUP (for regular kick proposed LUP is current LUP, for lender kick proposed LUP is calculated based on additional debt)
- in both kick cases return current LUP in kick result
- reduce gas costs by saving a Fenwick traversal
- reduce contract size by removing LUP calculation within Pool
* Cosmetic flashloan code changes, PoolCommons.flashLoan doesn't return false but always reverts if flashloan fails
* PR#983 style, remove redundant line
* PR#999 suggested improvement - calculate current settled debt only once and include in settle result for state update
* PR #962 proposed changes:
- get Fenwick deposits only once when settle with reserves
- define constants for min bond factor and max npTp ratio values
* PR #987 proposed improvement:
- add and reuse _htp helper function (instead duplicated maths)
* Continuation of PR #962: (#1008)
- Record settle amount limmit in Liquidtion struct, at the time of kick (that is instead incrementing accumulator in Borrower struct, each time debt is drawn)
- This way accumulator will be reseted when auction is settled
- fix tests
TODO:
- assert Liquidation.t0ReserveSettleAmount in unit tests (_assertAuction), make sure is set to 0 after auction settled and decreased when partial settles done
- update invariant test to check new introduced accumulator
* Misc test fixes (#1009)
* handle another reward rounding error use case
* fix intermittant fuzz test failure - cannot draw debt from liquidity in bucket 7388
* PositionManager should expect AddAboveAuctionPrice, which can happen in moveLiquidity
* Invariant fix: round up quote tokens calculated from rewarded LP (because LP rewarded are calculated in bucketTake as rewarded quote tokens -> LP rounded down)
* Pr feedback
* Fix failing unit tests

* RC9 suggested improvements (#1005)
* Revert AuctionNotTakeable in same place, load auction kickTime only once from storage
* Calculate ERC721 collateralTaken only once
cosmetize code (read from result struct in local var and reuse)
Results in shrinking a little bit contract sizes
* Read borrower Np Tp ratio from storage only once when kick
* If block style, proper indentation
* Proposed changes to PR #972:
- avoid calculating current LUP twice in lender kick
- change _kick function to accept proposed LUP (for regular kick proposed LUP is current LUP, for lender kick proposed LUP is calculated based on additional debt)
- in both kick cases return current LUP in kick result
- reduce gas costs by saving a Fenwick traversal
- reduce contract size by removing LUP calculation within Pool
* Cosmetic flashloan code changes, PoolCommons.flashLoan doesn't return false but always reverts if flashloan fails
* PR#983 style, remove redundant line
* PR#999 suggested improvement - calculate current settled debt only once and include in settle result for state update
* PR #962 proposed changes:
- get Fenwick deposits only once when settle with reserves
- define constants for min bond factor and max npTp ratio values
* PR #987 proposed improvement:
- add and reuse _htp helper function (instead duplicated maths)
* Continuation of PR #962: (#1008)
- Record settle amount limmit in Liquidtion struct, at the time of kick (that is instead incrementing accumulator in Borrower struct, each time debt is drawn)
- This way accumulator will be reseted when auction is settled
- fix tests
TODO:
- assert Liquidation.t0ReserveSettleAmount in unit tests (_assertAuction), make sure is set to 0 after auction settled and decreased when partial settles done
- update invariant test to check new introduced accumulator
* Misc test fixes (#1009)
* handle another reward rounding error use case
* fix intermittant fuzz test failure - cannot draw debt from liquidity in bucket 7388
* PositionManager should expect AddAboveAuctionPrice, which can happen in moveLiquidity
* Invariant fix: round up quote tokens calculated from rewarded LP (because LP rewarded are calculated in bucketTake as rewarded quote tokens -> LP rounded down)
* initial commit
* cleaned up, its executing
* updated
* rough draft of tests written
* cleaned up examples added collateral asserts
* borrower change not needed in PR
* added new class inside ERC721PoolLiquidationsTake.t.sol
* updated tests to adjust for take event
