De-abseil, part 2: mutex, locks, (most) time - util::Mutex is now a std::shared_timed_mutex, which is capable of exclusive and shared locks. - util::Lock is still present as a std::lock_guard<util::Mutex>. - the locking annotations are preserved, but updated to the latest supported by clang rather than using abseil's older/deprecated ones. - ACQUIRE_LOCK macro is gone since we don't pass mutexes by pointer into locks anymore (WTF abseil). - ReleasableLock is gone. Instead there are now some llarp::util helper methods to obtain unique and/or shared locks: - `auto lock = util::unique_lock(mutex);` gets an RAII-but-also unlockable object (std::unique_lock<T>, with T inferred from `mutex`). - `auto lock = util::shared_lock(mutex);` gets an RAII shared (i.e. "reader") lock of the mutex. - `auto lock = util::unique_locks(mutex1, mutex2, mutex3);` can be used to atomically lock multiple mutexes at once (returning a tuple of the locks). This are templated on the mutex which makes them a bit more flexible than using a concrete type: they can be used for any type of lockable mutex, not only util::Mutex. (Some of the code here uses them for getting locks around a std::mutex). Until C++17, using the RAII types is painfully verbose: ```C++ // pre-C++17 - needing to figure out the mutex type here is annoying: std::unique_lock<util::Mutex> lock(mutex); // pre-C++17 and even more verbose (but at least the type isn't needed): std::unique_lock<decltype(mutex)> lock(mutex); // our compromise: auto lock = util::unique_lock(mutex); // C++17: std::unique_lock lock(mutex); ``` All of these functions will also warn (under gcc or clang) if you discard the return value. You can also do fancy things like `auto l = util::unique_lock(mutex, std::adopt_lock)` (which lets a lock take over an already-locked mutex). - metrics code is gone, which also removes a big pile of code that was only used by metrics: - llarp::util::Scheduler - llarp::thread::TimerQueue - llarp::util::Stopwatch

Oxend error ping + unfunded tracking Currently (from a recent PR) we aren't pinging oxend if not active, but that behaviour ended up being quite wrong because lokinet needs to ping even when decommissioned or deregistered (when decommissioned we need the ping to get commissioned again, and if not registered we need the ping to get past the "lokinet isn't pinging" nag screen to prepare a registration). This considerably revises the pinging behaviour: - We ping oxend *unless* there is a specific error with our connections (i.e. we *should* be establishing peer connections but don't have any) - If we do have such an error, we send a new oxend "error" ping to report the error to oxend and get oxend to hold off on sending uptime proofs. Along the way this also changes how we handle the current node state: instead of just tracking deregistered/decommissioned, we now track three states: - LooksRegistered -- which means the SN is known to the network (but not necessarily active or fully staked) - LooksFunded -- which means it is known *and* is fully funded, but not necessarily active - LooksDecommissioned -- which means it is known, funded, and not currently active (which implies decommissioned). The funded (or more precisely, unfunded) state is now tracked in rc_lookup_handler in a "greenlist" -- i.e. new SNs that are so new (i.e. "green") that they aren't even fully staked or active yet.

Oxend error ping + unfunded tracking Currently (from a recent PR) we aren't pinging oxend if not active, but that behaviour ended up being quite wrong because lokinet needs to ping even when decommissioned or deregistered (when decommissioned we need the ping to get commissioned again, and if not registered we need the ping to get past the "lokinet isn't pinging" nag screen to prepare a registration). This considerably revises the pinging behaviour: - We ping oxend *unless* there is a specific error with our connections (i.e. we *should* be establishing peer connections but don't have any) - If we do have such an error, we send a new oxend "error" ping to report the error to oxend and get oxend to hold off on sending uptime proofs. Along the way this also changes how we handle the current node state: instead of just tracking deregistered/decommissioned, we now track three states: - LooksRegistered -- which means the SN is known to the network (but not necessarily active or fully staked) - LooksFunded -- which means it is known *and* is fully funded, but not necessarily active - LooksDecommissioned -- which means it is known, funded, and not currently active (which implies decommissioned). The funded (or more precisely, unfunded) state is now tracked in rc_lookup_handler in a "greenlist" -- i.e. new SNs that are so new (i.e. "green") that they aren't even fully staked or active yet.

De-abseil, part 2: mutex, locks, (most) time - util::Mutex is now a std::shared_timed_mutex, which is capable of exclusive and shared locks. - util::Lock is still present as a std::lock_guard<util::Mutex>. - the locking annotations are preserved, but updated to the latest supported by clang rather than using abseil's older/deprecated ones. - ACQUIRE_LOCK macro is gone since we don't pass mutexes by pointer into locks anymore (WTF abseil). - ReleasableLock is gone. Instead there are now some llarp::util helper methods to obtain unique and/or shared locks: - `auto lock = util::unique_lock(mutex);` gets an RAII-but-also unlockable object (std::unique_lock<T>, with T inferred from `mutex`). - `auto lock = util::shared_lock(mutex);` gets an RAII shared (i.e. "reader") lock of the mutex. - `auto lock = util::unique_locks(mutex1, mutex2, mutex3);` can be used to atomically lock multiple mutexes at once (returning a tuple of the locks). This are templated on the mutex which makes them a bit more flexible than using a concrete type: they can be used for any type of lockable mutex, not only util::Mutex. (Some of the code here uses them for getting locks around a std::mutex). Until C++17, using the RAII types is painfully verbose: ```C++ // pre-C++17 - needing to figure out the mutex type here is annoying: std::unique_lock<util::Mutex> lock(mutex); // pre-C++17 and even more verbose (but at least the type isn't needed): std::unique_lock<decltype(mutex)> lock(mutex); // our compromise: auto lock = util::unique_lock(mutex); // C++17: std::unique_lock lock(mutex); ``` All of these functions will also warn (under gcc or clang) if you discard the return value. You can also do fancy things like `auto l = util::unique_lock(mutex, std::adopt_lock)` (which lets a lock take over an already-locked mutex). - metrics code is gone, which also removes a big pile of code that was only used by metrics: - llarp::util::Scheduler - llarp::thread::TimerQueue - llarp::util::Stopwatch

De-abseil, part 2: mutex, locks, (most) time - util::Mutex is now a std::shared_timed_mutex, which is capable of exclusive and shared locks. - util::Lock is still present as a std::lock_guard<util::Mutex>. - the locking annotations are preserved, but updated to the latest supported by clang rather than using abseil's older/deprecated ones. - ACQUIRE_LOCK macro is gone since we don't pass mutexes by pointer into locks anymore (WTF abseil). - ReleasableLock is gone. Instead there are now some llarp::util helper methods to obtain unique and/or shared locks: - `auto lock = util::unique_lock(mutex);` gets an RAII-but-also unlockable object (std::unique_lock<T>, with T inferred from `mutex`). - `auto lock = util::shared_lock(mutex);` gets an RAII shared (i.e. "reader") lock of the mutex. - `auto lock = util::unique_locks(mutex1, mutex2, mutex3);` can be used to atomically lock multiple mutexes at once (returning a tuple of the locks). This are templated on the mutex which makes them a bit more flexible than using a concrete type: they can be used for any type of lockable mutex, not only util::Mutex. (Some of the code here uses them for getting locks around a std::mutex). Until C++17, using the RAII types is painfully verbose: ```C++ // pre-C++17 - needing to figure out the mutex type here is annoying: std::unique_lock<util::Mutex> lock(mutex); // pre-C++17 and even more verbose (but at least the type isn't needed): std::unique_lock<decltype(mutex)> lock(mutex); // our compromise: auto lock = util::unique_lock(mutex); // C++17: std::unique_lock lock(mutex); ``` All of these functions will also warn (under gcc or clang) if you discard the return value. You can also do fancy things like `auto l = util::unique_lock(mutex, std::adopt_lock)` (which lets a lock take over an already-locked mutex). - metrics code is gone, which also removes a big pile of code that was only used by metrics: - llarp::util::Scheduler - llarp::thread::TimerQueue - llarp::util::Stopwatch
