The object store contains cross-platform abstractions used in Realm products. It is not intended to be used directly.
The object store consists of the following components:
object_store
/schema
/object_schema
/property
- contains the structures and logic used to setup and modify Realm files and their schema.shared_realm
- wraps theobject_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.
Each Realm product may use only a subset of the provided components depending on its needs.
Please report bugs against the Realm product that you're using:
The object store's CMake build system currently only supports building for OS X, Linux, and Android.
The object store code supports being built for all Apple platforms, Linux and Android when used along with the relevant Realm product's build system.
-
Download dependencies:
git submodule update --init
-
Install CMake. You can download an installer for OS X from the CMake download page, or install via Homebrew:
brew install cmake
-
Generate build files:
cmake .
If building for Android, the path for the Android NDK must be specified. For example, if it was installed with homebrew:
cmake -DREALM_PLATFORM=Android -DANDROID_NDK=/usr/local/Cellar/android-ndk-r10e/r10e/ .
If you want to use XCode as your editor, you can generate a XCode project with:
cmake -G Xcode .
-
Build:
make
If you wish to build with sync enabled, invoke cmake
like so:
cmake -DREALM_ENABLE_SYNC=1
If you wish to build against a local version of core you can invoke cmake
like so:
cmake -DREALM_CORE_PREFIX=/path/to/realm-core
The given core tree will be built as part of the object store build.
Specify the path to realm-core and realm-sync when invoking cmake
:
cmake -DREALM_ENABLE_SYNC=1 -DREALM_CORE_PREFIX=/path/to/realm-core -DREALM_SYNC_PREFIX=/path/to/realm-sync
Prebuilt sync binaries are currently not supported.
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 invoking CMake.
Building with ASan requires specifying a path to core with -DREALM_CORE_PREFIX
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.
make run-tests
It requires a root device or an emulator:
make
adb push tests/tests /data/local/tmp
adb shell /data/local/tmp/tests
The Dockerfile
included in this repo will provision a Docker image suitable
for building and running tests for both the Linux and Android platforms.
# Build Docker image from Dockerfile
docker build -t "objectstore" .
# Run bash interactively from the built Docker image,
# mounting the current directory
docker run --rm -it -v $(pwd):/tmp -w /tmp objectstore bash
# Build the object store for Linux and run tests
> cmake .
> make
> make run-tests
Refer to the rest of this document for instructions to build/test in other configurations.
The .vscode
folder contains workspace configuration files for Visual Studio Code, which will be picked up by VSCode when it opens this folder. .vscode/extensions.json
contains a list of recommended IDE extensions - namely C++, CMake, and Catch2 support. Make sure to accept installing the recommended extensions the first time you open this repo in VSCode.
From the command palette execute CMake: Select Variant
and choose one of the predefined build variants, such as Debug + Enable Sync + Download Core
. Then, execute CMake: Configure
and CMake: Build
. Refer to the CMake Tools for Visual Studio Code guide for more details.
The Catch2 and Google Test Explorer extension enables exploring, running, and debugging individual test cases. Simply build the tests
target and execute the Test: Focus on Test Explorer View
VSCode command or manually switch to the Test Explorer view in the sidebar to get started.
