Dependencies

On non-Windows platforms, there is a dependency on Snappy library because ForestDB supports an option to compress a document body using Snappy. Please visit Snappy site for more details.

  • Ubuntu

    sudo apt-get install libsnappy-dev

  • CentOS

    wget https://snappy.googlecode.com/files/snappy-1.1.1.tar.gz

    tar -xvfz snappy-1.1.1.tar.gz

    cd snappy-1.1.1

    ./configure && make && sudo make install

  • OS X

    sudo brew install snappy

We also use the asynchronous I/O library libaio on Linux if it is available, to submit multiple I/O requests at once to speed up fetching non-resident blocks from disk. As of this time, we use libaio to read data blocks from the old file during the compaction.

  • Ubuntu

    sudo apt-get install libaio-devel

  • CentOS

    sudo yum install libaio-devel

We plan to support asynchronous I/O in other operating systems such as Windows and OS X, soon.

For better memory fragmentation and concurrency management, jemalloc can be linked to ForestDB if available on the host environment. Please visit jemalloc site for more information and install guideline.

Database encryption is also supported and can be enabled at compilation time. Currently, we support CommonCrypto library on iOS and OS X, OpenSSL, and LibTomCrypt.

Compilation and Build

We use CMake to provide the build support for a wide range of platforms. Please follow the instructions below to install CMake in your target platform.

  • Ubuntu

    sudo apt-get install cmake

  • Centos

    wget http://www.cmake.org/files/v2.8/cmake-2.8.12.1.tar.gz

    tar xvfz cmake-2.8.12.1.tar.gz

    cd cmake-2.8.12.1

    ./bootstrap && make && sudo make install

  • OS X

    brew install cmake

  • Windows

    Please download and install CMake binary for Windows from CMake download page.

Once CMake is installed, please follow the instructions below to compile and build ForestDB on Ubuntu, Centos, or OS X:

git clone git://github.com/couchbase/forestdb

cd forestdb

mkdir build

cd build

cmake ../

(The default value of CMAKE_BUILD_TYPE is RelWithDebInfo. If you want to build with optimizations disabled for debugging, type cmake -DCMAKE_BUILD_TYPE=Debug ../ instead.)

_JEMALLOC variable can be optionally set to 1 and passed to link jemalloc to ForestDB (cmake -D_JEMALLOC=1 ../)

_ENCRYPTION macro can be also optionally passed to specify which crypto library (commoncrypto, openssl, or libtomcrypt) is used to support database encryption (e.g., cmake -D_ENCRYPTION=commoncrypto ../)

make all

On Windows (using Visual Studio's CL compiler), the instructions are as follows:

git clone git://github.com/couchbase/forestdb (or clone repository using TortoiseGit)

cd forestdb

mkdir build

cd build

Note that the path and environment variables for command-line builds need to be set before moving to the next step. Please refer to the MSDN Page.

cmake -G "NMake Makefiles" ..\

(The default value of CMAKE_BUILD_TYPE is Debug. If you want to build with optimizations enabled for better performance, type cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release ../ instead.)

nmake all

Test

To run all the unit tests:

  • Ubuntu, Centos, and OS X

    make test

  • Windows

    nmake test

  • To enable code-coverage reporting for tests, install gcov and lcov for your OS. (Windows not supported). Also make sure build type is Coverage

    cmake -DCMAKE_BUILD_TYPE=Coverage ../

    make all

    make test_coverage

    This target will run the tests and output coverage report to <repo>/coverage/index.html

  • To enable valgrind tests, install valgrind for your OS. (Windows not supported). Also make sure build type is Valgrind

    cmake -DCMAKE_BUILD_TYPE=Valgrind ../

    make all

    make test_valgrind

    This target will run the tests and output the memory report to the console

  • By default, every run will produce an additional .lat file which indicates the latencies of the forestdb api. This is disabled if CMAKE_BUILD_TYPE=Release

  • To enable the use of threadsanitizer for tests, install clang 3.5+ (currently only Ubuntu 14.04 is supported). Also make sure to set flag CB_THREADSANITIZER

    cmake -DCMAKE_C_COMPILER=clang-3.5 -DCMAKE_CXX_COMPILER=clang++-3.5 -DCB_THREADSANITIZER=1 ..

    make all

    make test

    Alternatively you can manually run tests under build/tests// for real-time analysis. When running as standalone it is recommended to include false error suppressions:

    TSAN_OPTIONS="second_deadlock_stack=1 suppressions=../../../cmake/Modules/tsan.suppressions" ./fdb_functional_test

  • For hardware accelerated CRC32C which can improve ForestDB performance, please fetch the optional couchbase platform repository into the forestdb source directory before building.

    cd forestdb

    git clone https://github.com/couchbase/platform.git

    Follow the rest of the platform specific build instructions from above
