2022-03-24scheduler: Capture ‘this’ explicitly in lambdaMarcoFalke
Without the changes, g++ will warn to compile under C++20: scheduler.cpp:114:21: warning: implicit capture of ‘this’ via ‘[=]’ is deprecated in C++20 [-Wdeprecated] 114 | scheduleFromNow([=] { Repeat(*this, f, delta); }, delta); | ^ scheduler.cpp:114:21: note: add explicit ‘this’ or ‘*this’ capture

2020-03-06scheduler: switch from boost to stdAnthony Towns
Changes from boost::chrono to std::chrono, boost::condition_var to std::condition_var, boost::mutex to sync.h Mutex, and reverselock.h to sync.h REVERSE_LOCK. Also adds threadsafety annotations to CScheduler members.

2019-11-12Run background seeding periodically instead of unpredictablyPieter Wuille
* Instead of calling RandAddSeedSleep anytime the scheduler goes idle, call its replacement (RandAddSeedPeriodic) just once per minute. This has better guarantees of actually being run, and helps limit how frequently the dynamic env data is gathered. * Since this code runs once per minute regardless now, we no longer need to keep track of the last time strengthening was run; just do it always. * Make strengthening time context dependent (100 ms at startup, 10 ms once per minute afterwards).
2019-01-16Switch all RNG code to the built-in PRNG.Pieter Wuille
It includes the following policy changes: * All GetRand* functions seed the stack pointer and rdrand result (in addition to the performance counter) * The periodic entropy added by the idle scheduler now seeds stack pointer, rdrand and perfmon data (once every 10 minutes) in addition to just a sleep timing. * The entropy added when calling GetStrongRandBytes no longer includes the once-per-10-minutes perfmon data on windows (it is moved to the idle scheduler instead, where latency matters less). Other changes: * OpenSSL is no longer seeded directly anywhere. Instead, any generated randomness through our own RNG is fed back to OpenSSL (after an additional hashing step to prevent leaking our RNG state). * Seeding that was previously done directly in RandAddSeedSleep is now moved to SeedSleep(), which is indirectly invoked through ProcRand from RandAddSeedSleep. * Seeding that was previously done directly in GetStrongRandBytes() is now moved to SeedSlow(), which is indirectly invoked through ProcRand from GetStrongRandBytes().

2017-07-23Add missing lock in CScheduler::AreThreadsServicingQueue()Matt Corallo
Not an actual bug as this is only used in asserts right now, but nice to not have a missing lock.
2017-07-10Expose if CScheduler is being serviced, assert its not in EmptyQueueMatt Corallo
2017-07-07Flush CValidationInterface callbacks prior to destructionMatt Corallo
Note that the CScheduler thread cant be running at this point, it has already been stopped with the rest of the init threadgroup. Thus, just calling any remaining loose callbacks during Shutdown() is sane.
2017-07-07Support more than one CScheduler thread for serial clientsMatt Corallo
This will be used by CValidationInterface soon. This requires a bit of work as we need to ensure that most of our callbacks happen in-order (to avoid synchronization issues in wallet) - we keep our own internal queue and push things onto it, scheduling a queue-draining function immediately upon new callbacks.

2016-11-18test: Fix use-after-free in scheduler testsWladimir J. van der Laan
Make a copy of the boost time-point to wait for, otherwise the head of the queue may be deleted by another thread while this one is waiting, while the boost function still has a reference to it. Although this problem is in non-test code, this is not an actual problem outside of the tests because we use the thread scheduler with only one service thread, so there will never be threads fighting at the head of the queue. The old boost fallback escapes this problem because it passes a scalar value to wait_until instead of a const object reference. Found by running the tests in LLVM-4.0-master asan.

2015-06-15Fix scheduler build with some boost versions.Cory Fields
Some boost versions have a conflicting overload of wait_until that returns void. Explicitly use a template here to avoid hitting that overload.
2015-05-21Fix intermittent hang issue in scheduler_testsWladimir J. van der Laan
Don't clear `stopRequested` and `stopWhenEmpty` at the top of `serviceQueue`, as this results in a race condition: on systems under heavy load, some of the threads only get scheduled on the CPU when the other threads have already finished their work. This causes the flags to be cleared post-hoc and thus those threads to wait forever. The potential drawback of this change is that the scheduler cannot be restarted after being stopped (an explicit reset would be needed), but we don't use this functionality anyway.
2015-05-16More robust CScheduler unit testGavin Andresen
On a busy or slow system, the CScheduler unit test could fail because it assumed all threads would be done after a couple of milliseconds. Replace the hard-coded sleep with CScheduler stop() method that will cleanly exit the servicing threads when all tasks are completely finished.
