    • importer: fix possible data loss on writeback · e387ad59
      If the source DB is lost during the import and then restored from a backup,
      all new transactions have to written back again on resume. It is the most
      common case for which the writeback hits the maximum number of transactions
      per partition to process at each iteration; the previous code was buggy in
      that it could skip transactions.

    • client: fix race condition between Storage.load() and invalidations · a2e278d5
      This fixes a bug that could manifest as follows:
      
        Traceback (most recent call last):
          File "neo/client/app.py", line 432, in load
            self._cache.store(oid, data, tid, next_tid)
          File "neo/client/cache.py", line 223, in store
            assert item.tid == tid, (item, tid)
        AssertionError: (<CacheItem oid='\x00\x00\x00\x00\x00\x00\x00\x01' tid='\x03\xcb\xc6\xca\xfd\xc7\xda\xee' next_tid='\x03\xcb\xc6\xca\xfd\xd8\t\x88' data='...' counter=1 level=1 expire=10000 prev=<...> next=<...>>, '\x03\xcb\xc6\xca\xfd\xd8\t\x88')
      
      The big changes in the threaded test framework are required because we need to
      reproduce a race condition between client threads and this conflicts with the
      serialization of epoll events (deadlock).
