surtur	d404681889	feat: "prepare to add proper entropy source" nits ... general * make greater use of "this" Fortuna * declare da_pools as a proper std::array of 32 Pool objects * declare da_pools as const * use std::shared_ptr _p_pools to access da_pools and share access to it * reflect change of pools[] -> std::array in how the array elements are accessed, which is a) via _p_pools pointer and b) using ".at(i)" function * pass _p_pools shared_ptr to Accumulator * refactor member function names and variable names * add member function attribute [[optimize_for_synchronized]] * secure conversions with static_cast-s Accumulator * make use of _p_pools * add _p_pools-related member functions * add a static constexpr variable NUM_OF_POOLS UrandomEntropySrc * implement event adding logic using _p_pools * make std::vector<char> non-static in urandom_entropy_src * implement proper urandom entropy source event "sourcing" (from /dev/urandom), event adding, clear bytes array at the end * properly convert using reinterpret_cast * protect access to the main function with std::lock_guard * receive EventAdderImpl as a ref * use return value from "add_entropy()" member function and create sanity guard checking the return code "int ret" EventAdder * pass event (std::vector<char>) by const& EventAdderImpl * make use of _p_pools shared_ptr * implement proper pool-rotating event-adding logic Pool * delete all copy constructors and assignment operator, the objects will not be copied or assigned to * receive parameters by const& where possible/sensible * handle concurrency: * declare std:string s as mutable * declare a rw std::mutex intended for writing and mutable std::recursive_mutex for read-only operations in const member functions ref: https://herbsutter.com/2013/05/24/gotw-6a-const-correctness-part-1-3/ ref: https://arne-mertz.de/2017/10/mutable/ * use std::lock_guard and std::unique_lock * refactor "add_entropy()" member function * get rid of intermediate "event_str" and directly use the "event" std::vector<char> for all operations * add a lock guard to prevent multiple threads (should that route be taken) from modifying pool resources simultaneously * add all_ok bool for basic sanity checking * add print statements (at least for now) * rename "get_s_length()" member function to "get_s_byte_count()" and repurpose it to return byte count of the stored entropy std::string s	2022-01-17 08:27:24 +01:00
