surtur	03578f9016	accumulator: refactor entropy_src,add files ... * add event_scheduler_impl.h and properly override its base class * add urandom_entropy_src.cpp, move there logic from header * add urandom_entropy_src.cpp to CMakeLists.txt * add unique_ptr per impl: one for both EventSchedulerImpl and EventAdderImpl each * wrap a call in reinterpret_cast and reformat code * add missing includes (best effort)	2022-01-13 05:40:33 +01:00
surtur	795b9ffe54	add proper SeedFileManager implementation ... a couple of fixes/necessary additions were made along the way, namely: * add a default constructor for DoTask * rework of the mutex/lock_guard/unique_lock logic in generator/fortuna * add .fortuna.seed to the list of the ignored (.gitignore) * add helper function to util for convertin bytes to blocks (16b==block) * add a wrapper for around the SeedFileManager instance and a way to see if it's dead or alive (so that it can be restarted if needed) * the timeout for saving of the seed file has been decreased to a more reasonable value than 10 minutes (I wouldn't want to lose potentially up to 10 minutes worth of entropy)	2022-01-09 11:58:38 +01:00
