Teon Banek 98cbd2b500 Cleanup utils::File API 
Summary:
Close the file descriptor in File destructor. This will prevent
accidental crashes during unexpected destructor calls. For example, if
an exception is thrown before the file is closed. File now takes
ownership of the descriptor. These changes now honor RAII idiom, which
should handle most of the peculiarities of C++.

Use optional value for TryOpenFile function, instead of returning a File
without a descriptor. It makes the failure state more semantically clear
to the API user.

Merge utils/filesystem with utils/file

The files aren't that big, and the naming is a bit confusing because
functions aren't really grouped for file and filesystem distinction.

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
