Redox GitLab consists of a large number of Projects and Subprojects. The difference between a Project and a Subproject is somewhat blurred in Redox GitLab, so we generally refer to the
redox project as the main project and the others as subprojects. On the Redox GitLab website, you will find the projects organized as a very large, flat alphabetical list. This is not indicative of the role or importance of the various projects.
redox project is actually just the root of the build system. It does not contain any of the code that the final Redox image will include. It includes the Makefiles, configuration files, and a few scripts to simplify setup and building. The
redox project can be found here.
git clone of
--recursive fetches the full build system, as described in the
.gitmodules file. The submodules are referred to using an SHA to identify what commit to use, so it's possible that your fetched subprojects do not have the latest from their
master branch. Once the latest SHA reference is merged into
redox, you can update to get the latest version of the subproject.
The many packages that are assembled into the Redox image are built from the corresponding subprojects. The name of a Redox package almost always matches the name of its subproject, although this is not enforced.
The recipe for a Redox package contains the instructions to fetch and build the package, for its inclusion in the Redox image. The recipe is stored with the Cookbook, not with with package.
cookbook subproject contains the mechanism for building the Redox packages. It also contains the recipes. If a recipe is modified, it is updated in the
cookbook subproject. In order for the updated recipe to get included in your fetched cookbook, the
redox project needs to be updated with the new
cookbook SHA. Connect with us on Chat if a recipe is not getting updated.
Some subprojects are built as Crates, and included in Redox packages using Cargo's package management system. Updates to a crate subproject must be pushed to the crate repository in order for it to be included in your build.
Some recipes obtain source code from places other than Redox GitLab. The cookbook mechanism can pull in source from any git URL. It can also obtain source tarballs, as is frequently the case for non-Rust applications.
In some cases, the Redox GitLab has a fork of another repository, in order to add Redox-specific patches. Where possible, we try to push these changes upstream, but there are many reasons why this might not be feasible.
When you are contributing to Redox, you are expected to make your changes in a Personal Fork of the relevant project, then create a Merge Request (PR) to have your changes pulled from your fork into the master. Note that your personal fork is required to have public visibility.
In some rare situations, e.g. for experimental features or projects with licensing that is not compatible with Redox, a recipe may pull in sources located in a personal repository. Before using one of these recipes, please check with us on Chat to understand why the project is set up this way, and do not commit a Redox config file containing such a recipe without permission.
