2019-01-25Prevent mutex lock fail even if --enable-debugAkio Nakamura
This PR intends to resolve #15227. "configure --debug-enabled" enables "#ifdef DEBUG_LOCKORDER". Then "lockdata" (in sync.cpp) will be initialized same as other static objects. But unfortunately, lockdata.push_lock() was called before its initialization (via initializing signatureCache which is declared in script/sigcache.cpp) on macOS. This PR apply the "Construct On First Use Idiom" to "lockdata" to prevent it.

Most logs should terminated with a '\n'. Some logs are built up over multiple calls to logPrintf(), so do not need a newline terminater. Comment all of these 'continued' logs as a linter hing.

2016-04-10Clean up lockorder data of destroyed mutexesPieter Wuille
The lockorder potential deadlock detection works by remembering for each lock A that is acquired while holding another B the pair (A,B), and triggering a warning when (B,A) already exists in the table. A and B in the above text are represented by pointers to the CCriticalSection object that is acquired. This does mean however that we need to clean up the table entries that refer to any critical section which is destroyed, as it memory address can potentially be used for another unrelated lock in the future. Implement this clean up by remembering not only the pairs in forward direction, but also backward direction. This allows for fast iteration over all pairs that use a deleted CCriticalSection in either the first or the second position.
