With this commit, users are able to build valkey using `CMake`. ## Example usage: Build `valkey-server` in Release mode with TLS enabled and using `jemalloc` as the allocator: ```bash mkdir build-release cd $_ cmake .. -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX=/tmp/valkey-install \ -DBUILD_MALLOC=jemalloc -DBUILD_TLS=1 make -j$(nproc) install # start valkey /tmp/valkey-install/bin/valkey-server ``` Build `valkey-unit-tests`: ```bash mkdir build-release-ut cd $_ cmake .. -DCMAKE_BUILD_TYPE=Release \ -DBUILD_MALLOC=jemalloc -DBUILD_UNIT_TESTS=1 make -j$(nproc) # Run the tests ./bin/valkey-unit-tests ``` Current features supported by this PR: - Building against different allocators: (`jemalloc`, `tcmalloc`, `tcmalloc_minimal` and `libc`), e.g. to enable `jemalloc` pass `-DBUILD_MALLOC=jemalloc` to `cmake` - OpenSSL builds (to enable TLS, pass `-DBUILD_TLS=1` to `cmake`) - Sanitizier: pass `-DBUILD_SANITIZER=<address|thread|undefined>` to `cmake` - Install target + redis symbolic links - Build `valkey-unit-tests` executable - Standard CMake variables are supported. e.g. to install `valkey` under `/home/you/root` pass `-DCMAKE_INSTALL_PREFIX=/home/you/root` Why using `CMake`? To list *some* of the advantages of using `CMake`: - Superior IDE integrations: cmake generates the file `compile_commands.json` which is required by `clangd` to get a compiler accuracy code completion (in other words: your VScode will thank you) - Out of the source build tree: with the current build system, object files are created all over the place polluting the build source tree, the best practice is to build the project on a separate folder - Multiple build types co-existing: with the current build system, it is often hard to have multiple build configurations. With cmake you can do it easily: - It is the de-facto standard for C/C++ project these days More build examples: ASAN build: ```bash mkdir build-asan cd $_ cmake .. -DBUILD_SANITIZER=address -DBUILD_MALLOC=libc make -j$(nproc) ``` ASAN with jemalloc: ```bash mkdir build-asan-jemalloc cd $_ cmake .. -DBUILD_SANITIZER=address -DBUILD_MALLOC=jemalloc make -j$(nproc) ``` As seen by the previous examples, any combination is allowed and co-exist on the same source tree. ## Valkey installation With this new `CMake`, it is possible to install the binary by running `make install` or creating a package `make package` (currently supported on Debian like distros) ### Example 1: build & install using `make install`: ```bash mkdir build-release cd $_ cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/valkey-install -DCMAKE_BUILD_TYPE=Release make -j$(nproc) install # valkey is now installed under $HOME/valkey-install ``` ### Example 2: create a `.deb` installer: ```bash mkdir build-release cd $_ cmake .. -DCMAKE_BUILD_TYPE=Release make -j$(nproc) package # ... CPack deb generation output sudo gdebi -n ./valkey_8.1.0_amd64.deb # valkey is now installed under /opt/valkey ``` ### Example 3: create installer for non Debian systems (e.g. FreeBSD or macOS): ```bash mkdir build-release cd $_ cmake .. -DCMAKE_BUILD_TYPE=Release make -j$(nproc) package mkdir -p /opt/valkey && ./valkey-8.1.0-Darwin.sh --prefix=/opt/valkey --exclude-subdir # valkey-server is now installed under /opt/valkey ``` Signed-off-by: Eran Ifrah <eifrah@amazon.com>
jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: http://jemalloc.net/
