* Fix -Wterminate warnings in rollback.cpp as wellest312016-07-08
| | | | Fix #4137 for rollback.cpp as well.
* Fix rollback.txt migrationShadowNinja2016-05-23
| | | | | Broken by b1965ac20922e3722392114bd63a22b403dcbe98. This also prepares the begin and commit statements only once.
* Improve rollback database indexingcheapie2015-10-24
| | | | Index more columns in the action table of the rollback DB to improve the performance of /rollback_check
* Flush rollback log more oftenest312015-10-24
| | | | | | | | | | | | Flushes the buffer of rollback actions that wait to get saved in two more situations: 1. Flushes in the destructor of the rollback. This makes the server not forget the last < 500 rollback entries when it shuts down. 2. Flushes the rollback when /rollback_check is invoked. This is neccessary as otherwise it leads to confusion if users want to test the rollback functionality by placing a node and then executing the check on it, or if the actions were very recent out of other reasons.
