+# Continous integration scripts
+
+## TravisCI
+
+For testing on Linux and macOS we use [TravisCI](https://travis-ci.org/)
+
+TravisCI consumes the `.travis.yml` file in the root of the repository
+to tell it how to build and test Z3.
+
+However the logic for building and test Z3 is kept out of this file
+and instead in a set of scripts in `scripts/`. This avoids
+coupling the build to TravisCI tightly so we can migrate to another
+service if required in the future.
+
+The scripts rely on a set of environment variables to control the configuration
+of the build. The `.travis.yml` declares a list of configuration with each
+configuration setting different environment variables.
+
+Note that the build scripts currently only support Z3 built with CMake. Support
+for building Z3 using the older Python/Makefile build system might be added in
+the future.
+
+### Configuration variables
+
+* `ASAN_BUILD` - Do [AddressSanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizer) build (`0` or `1`)
+* `BUILD_DOCS` - Build API documentation (`0` or `1`)
+* `C_COMPILER` - Path to C Compiler
+* `CXX_COMPILER` - Path to C++ Compiler
+* `DOTNET_BINDINGS` - Build and test .NET API bindings (`0` or `1`)
+* `JAVA_BINDINGS` - Build and test Java API bindings (`0` or `1`)
+* `NO_SUPPRESS_OUTPUT` - Don't suppress output of some commands (`0` or `1`)
+* `PYTHON_BINDINGS` - Build and test Python API bindings (`0` or `1`)
+* `RUN_SYSTEM_TESTS` - Run system tests (`0` or `1`)
+* `RUN_UNIT_TESTS` - Run unit tests (`0` or `1`)
+* `TARGET_ARCH` - Target architecture (`x86_64` or `i686`)
+* `TEST_INSTALL` - Test running `install` target (`0` or `1`)
+* `UBSAN_BUILD` - Do [UndefinedBehaviourSanitizer](https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html) build (`0` or `1`)
+* `USE_LIBGMP` - Use [GNU multiple precision library](https://gmplib.org/) (`0` or `1`)
+* `USE_LTO` - Link binaries using link time optimization (`0` or `1`)
+* `USE_OPENMP` - Use OpenMP (`0` or `1`)
+* `Z3_BUILD_TYPE` - CMake build type (`RelWithDebInfo`, `Release`, `Debug`, or `MinSizeRel`)
+* `Z3_CMAKE_GENERATOR` - CMake generator (`Ninja` or `Unix Makefiles`)
+* `Z3_VERBOSE_BUILD_OUTPUT` - Show compile commands in CMake builds (`0` or `1`)
+* `Z3_STATIC_BUILD` - Build Z3 binaries and libraries statically (`0` or `1`)
+* `Z3_SYSTEM_TEST_GIT_REVISION` - Git revision of [z3test](https://github.com/Z3Prover/z3test). If empty lastest revision will be used.
+
+### Linux
+
+For Linux we use Docker to perform the build so that it easily reproducible
+on a local machine and so that we can avoid depending on TravisCI's environment
+and instead use a Linux distribution of our choice.
+
+The `scripts/travis_ci_linux_entry_point.sh` script
+
+1. Creates a base image containing all the dependencies needed to build and test Z3
+2. Builds and tests Z3 using the base image propagating configuration environment
+   variables (if set) into the build using the `--build-arg` argument of the `docker run`
+   command.
+
+If an environemnt variable is not set a defaults value is used which can be
+found in `Dockerfiles/z3_build.Dockerfile`.
+
+#### Linux specific configuration variables
+
+* `LINUX_BASE` - The base docker image identifier to use (`ubuntu_16.04`, `ubuntu32_16.04`, or `ubuntu_14.04`).
+
+#### Reproducing a build locally
+
+A build can be reproduced locally by using the `scripts/travis_ci_linux_entry_point.sh`
+script and setting the appropriate environment variable.
+
+For example lets say we wanted to reproduce the build below.
+
+```yaml
+
+  - LINUX_BASE=ubuntu_16.04 C_COMPILER=/usr/bin/gcc-5 CXX_COMPILER=/usr/bin/g++-5 TARGET_ARCH=x86_64 Z3_BUILD_TYPE=RelWithDebInfo
+```
+
+This can be done by running the command
+
+```bash
+LINUX_BASE=ubuntu_16.04 C_COMPILER=/usr/bin/gcc-5 CXX_COMPILER=/usr/bin/g++-5 TARGET_ARCH=x86_64 Z3_BUILD_TYPE=RelWithDebInfo scripts/travis_ci_linux_entry_point.sh
+```
+
+The `docker build` command which we use internally supports caching. What this
+means in practice is that re-running the above command will re-use successfully
+completed stages of the build provided they haven't changed. This requires that
+the `Dockerfiles/z3_build.Dockerfile` is carefully crafted to avoid invalidating
+the cache when unrelated files sent to the build context change.
+
+#### TravisCI docker image cache
+
+To improve build times the Z3 base docker images are cached using
+[TravisCI's cache directory feature](https://docs.travis-ci.com/user/caching).
+If the `DOCKER_TRAVIS_CI_CACHE_DIR` environment variable is set (see `.travis.yml`)
+then the directory pointed to by the environment variable is used as a cache
+for Docker images.
+
+The logic for this can be found in `scripts/travis_ci_linux_entry_point.sh`.
+The build time improvements are rather modest (~ 2 minutes) and the cache is
+rather large due to TravisCI giving each configuration its own cache. So this
+feature might be removed in the future.
+
+It may be better to just build the base image once (outside of TravisCI), upload
+it to [DockerHub](https://hub.docker.com/) and have the build pull down the pre-built
+image everytime.
+
+An [organization](https://hub.docker.com/u/z3prover/) has been created on
+DockerHub for this.
