Any projects which want to use Hush code from now on will need to be licensed as
GPLv3 or we will send the lawyers: https://www.softwarefreedom.org/
Notably, Komodo (KMD) is licensed as GPLv2 and is no longer compatible to receive
code changes, without causing legal issues. MIT projects, such as Zcash, also cannot pull
in changes from the Hush Full Node without permission from The Hush Developers,
which may in some circumstances grant an MIT license on a case-by-case basis.
Strictly speaking this is not a true deduplication; the test output will be
slightly different (due to inconsistent print statements) but I think this is
close enough.
The mempool was not synced so a block could be generated and not
clear out the mempool. This would then cause subsequent code
which expected the mempool of all nodes to be empty to hang.
The new parameter is to satisfy the principle of least astonishment
by providing a sensible default for the maximum number of transparent
inputs to shield. If users do not configure -mempooltxinputlimit
it is possible for them to create transactions with hundreds of
inputs which suffer from mining delay, due to the current state of
the network where some miners have configured -mempooltxinputlimit
as a way to deal with the problem of quadratic hashing.
