This change removes a mapValue.erase("version") statement which deletes a
mapValue entry that never existed. The statement was mistakenly added in commit
865c3a2383 in 2010 and is harmless but confusing.
This resolves an issue where a wallet transaction which failed to
relay previously because it couldn't make it into the mempool
will not try again until restart, even though mempool conditions
may have changed.
Abandoned and known-conflicted transactions are skipped.
Some concern was expressed that there may be users with many
unknown conflicts would waste a lot of CPU time trying to
add them to their memory pools over and over again. But I am
doubtful these users exist in any number, if they do exist
they have worse problems, and they can mitigate any performance
issue this might have by abandoning the transactions in question.
Remove the nType and nVersion as parameters to all serialization methods
and functions. There is only one place where it's read and has an impact
(in CAddress), and even there it does not impact any of the recursively
invoked serializers.
Instead, the few places that need nType or nVersion are changed to read
it directly from the stream object, through GetType() and GetVersion()
methods which are added to all stream classes.
Recent discussion (in IRC meetings, and e.g. #8989) has shown a
preference for the default confirm target for smartfees to be 6 instead
of 2, to avoid overpaying fees for questionable gain.
6 is also a compromise between the GUI's pre-#8989 value of 25 and the
bitcoind `-txconfirmtarget` default of 2. These were unified in #8989,
but this has made the (overly expensive) default of 2 as GUI default.
