Martin Braun b6119e581e uhd: Replace Boost mutexes and locks with standard options ... This is a very mechanical task that could almost have been done with sed. Boost versions of mutexes and locks were removed, and replaced with std:: versions. The replacement tables are as follows: == Mutexes == - boost::mutex -> std::mutex - boost::recursive_mutex -> std::recursive_mutex Mutexes behave identically between Boost and std:: and have the same API. == Locks == C++11 has only two types of lock that we use/need in UHD: - std::lock_guard: Identical to boost::lock_guard - std::unique_lock: Identical to boost::unique_lock Boost also has boost::mutex::scoped_lock, which is a typedef for boost::unique_lock<>. However, we often have used scoped_lock where we meant to use lock_guard<>. The name is a bit misleading, "scoped lock" sounding a bit like an RAII mechanism. Therefore, some previous boost::mutex::scoped_lock are now std::lock_guard<>. std::unique_lock is required when doing more than RAII locking (i.e., unlocking, relocking, usage with condition variables, etc.). == Condition Variables == Condition variables were out of the scope of this lock/mutex change, but in UHD, we inconsistently use boost::condition vs. boost::condition_variable. The former is a templated version of the latter, and thus works fine with std::mutex'es. Therefore, some boost::condition_variable where changed to boost::condition. All locks and mutexes use `#include <mutex>`. The corresponding Boost includes were removed. In some cases, this exposed issues with implicit Boost includes elsewhere. The missing explicit includes were added.		2021-10-19 12:21:33 -07:00
