Realm Object Store

Cross-platform code used accross bindings. Binding developers can choose to use some or all the included functionality:

  • object_store/schema/object_schema/property - contains the structures and logic used to setup and modify realm files and their schema.
  • shared_realm - wraps the object_store apis to provide transactions, notifications, realm caching, migrations, and other higher level functionality.
  • object_accessor/results/list - accessor classes, object creation/update pipeline, and helpers for creating platform specific property getters and setters.
  • parser/query_builder - cross platform query parser and query builder - requires and object_accessor specialization for argument support. Depends on https://github.com/ColinH/PEGTL

Building

The object store's build system currently only suports building for OS X. The object store itself can build for all Apple platforms when integrated into a binding.

  1. Download PEGTL dependency

    git submodule update --init

  2. Install CMake. You can download an installer for OS X from the CMake download page, or install via Homebrew:

    brew install cmake

  3. Generate build files:

    cmake .

  4. Build:

    make

If you wish to build against a local version of core you can invoke cmake like so:

cmake -DREALM_CORE_VERSION=/path/to/realm-core

The given core tree will be built as part of the object store build.

Building with Sanitizers

The object store can be built using ASan, TSan and/or UBSan by specifying -DSANITIZE_ADDRESS=1, -DSANITIZE_THREAD=1, or -DSANITIZE_UNDEFINED=1 when inoking CMake. Building with ASan requires specifying a path to core with -DREAM_CORE_VERSION as core needs to also be built with ASan enabled.

On OS X, the Xcode-provided copy of Clang only comes with ASan, and using TSan or UBSan requires a custom build of Clang. If you have installed Clang as an external Xcode toolchain (using the install-xcode-toolchain when building LLVM), note that you'll have to specify -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ when running cmake to stop cmake from being too clever.
