Without this amendment, an NFTokenAcceptOffer transaction can succeed even when the NFToken recipient does not have sufficient reserves for the new NFTokenPage. This allowed accounts to accept NFT sell offers without having a sufficient reserve. (However, there was no issue in brokered mode or when a buy offer is involved.) Instead, the transaction should fail with `tecINSUFFICIENT_RESERVE` as appropriate. The `fixNFTokenReserve` amendment adds checks in the NFTokenAcceptOffer transactor to check if the OwnerCount changed. If it did, then it checks the new reserve requirement. Fix #4679
rippled Source
Some of these directories come from entire outside repositories brought in
using [git-subtree][]. This means that the source files are inserted directly
into the rippled repository. They can be edited and committed just as if they
were normal files.
[git-subtree]: https://github.com/apenwarr/git-subtree
If you create a commit that contains files both from a subtree, and from the
rippled source tree, please use care when designing the commit message, since
it will appear in the subtree's individual repository when the changes are
pushed back to the upstream. Better yet, do not mix files from subtrees and
ripple in the same commit at all.
