By throwing in reverselock's destructor if it's lock has been tampered with, the likely result is std::terminate being called. Indeed that happened before this change. Once reverselock has taken another lock (its ctor didn't throw), it makes no sense to try to grab or lock the parent lock. That is be broken/undefined behavior depending on the parent lock's implementation, but it shouldn't cause the reverselock to fail to re-lock when destroyed. To avoid those problems, simply swap the parent lock's contents with a dummy for the duration of the lock. That will ensure that any undefined behavior is caught at the call-site rather than the reverse lock's destruction. Barring a failed mutex unlock which would be indicative of a larger problem, the destructor should now never throw. --- src/reverselock.h | 7 +++++-- src/test/reverselock_tests.cpp | 16 ++++++---------- 2 files changed, 11 insertions(+), 12 deletions(-) diff --git a/src/reverselock.h b/src/reverselock.h index db5c626c958..fac1ccb7931 100644 --- a/src/reverselock.h +++ b/src/reverselock.h @@ -15,10 +15,12 @@ class reverse_lock explicit reverse_lock(Lock& lock) : lock(lock) { lock.unlock(); + lock.swap(templock); } - ~reverse_lock() noexcept(false) { - lock.lock(); + ~reverse_lock() { + templock.lock(); + templock.swap(lock); } private: @@ -26,6 +28,7 @@ class reverse_lock reverse_lock& operator=(reverse_lock const&); Lock& lock; + Lock templock; }; #endif // BITCOIN_REVERSELOCK_H diff --git a/src/test/reverselock_tests.cpp b/src/test/reverselock_tests.cpp index e7e627ae0f2..8bdff97000f 100644 --- a/src/test/reverselock_tests.cpp +++ b/src/test/reverselock_tests.cpp @@ -42,22 +42,18 @@ BOOST_AUTO_TEST_CASE(reverselock_errors) BOOST_CHECK(failed); BOOST_CHECK(!lock.owns_lock()); - // Make sure trying to lock a lock after it has been reverse locked fails - failed = false; - bool locked = false; + // Locking the original lock after it has been taken by a reverse lock + // makes no sense.
