| * | | | Added feeler connections increasing good addrs in the tried table.Ethan Heilman2016-08-231-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tests if addresses are online or offline by briefly connecting to them. These short lived connections are referred to as feeler connections. Feeler connections are designed to increase the number of fresh online addresses in tried by selecting and connecting to addresses in new. One feeler connection is attempted on average once every two minutes. This change was suggested as Countermeasure 4 in Eclipse Attacks on Bitcoin’s Peer-to-Peer Network, Ethan Heilman, Alison Kendler, Aviv Zohar, Sharon Goldberg. ePrint Archive Report 2015/263. March 2015.

| * | | util: Remove zero-argument versions of LogPrint and errorWladimir J. van der Laan2016-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes in tinyformat, recently imported from upstream have made the zero-argument versions of formatting functions unnecessary. Remove them. This is a slight semantic change: `%` characters in the zero-argument call are now regarded and need to be escaped. As for as I know, the only use of this is in `main.cpp`.

| |/ / | | | | | | | | | | | | | | | | | | | | | Moves the IsStandard check to happen after the premature-witness check, so that adding a witness to a transaction can't prevent mempool acceptance. Note that this doesn't address the broader category of potential mempool DoS issues that affect transactions after segwit activation.
