Summary:
Instead of calling the wanted method, this diff takes copies of both `is_replicated(x)` and `is_active(x)` results so that they can't change during the method execution.
The problem with the previous implementation was that the information about a
log could change during two consecutive queries as ilustrated in the example
below.
```
Thread 1 Thread2
rlog->set_active(1);
if (rlog->is_replicated(1)) return true;
rlog->set_replicated(1);
if (rlog->is_active(1)) return false;
throw InvalidLogReplicationLookup();
```
The snippet above would throw as we don't have any information about the log
`1`, because the `set_replicated` call would "shadow" the active bit.

memgraph
Memgraph is an ACID compliant high performance transactional distributed in-memory graph database featuring runtime native query compiling, lock free data structures, multi-version concurrency control and asynchronous IO.
dependencies
Memgraph can be compiled using any modern c++ compiler. It mostly relies on the standard template library, however, some things do require external libraries.
Some code contains linux-specific libraries and the build is only supported on a 64 bit linux kernel.
- linux
- clang 3.8 (good c++11 support, especially lock free atomics)
- antlr (compiler frontend)
- cppitertools
- fmt format
- google benchmark
- google test
- glog
- gflags
