Mirror of the R svn with CI for testing patches

R-SVN CI tool

A mirror of R svn-trunk for tracking changes and testing patches using GitHub actions.

How it works

This mirror synchronises every 15 minutes with the official R svn server. Each new commit triggers a build on every platform, and the results are published on: https://contributor.r-project.org/svn-dashboard, which shows an overview of the most recent revisions, including links to the build logs.

The Github icon in the last column links to the GitHub actions page for each build, where you can also download the generated Windows installer. These installers are not signed, they are only for testing.

Testing patches

You can also use this mirror to generate and test patches that you want to propose for base-R:

1. Fork this repository by clicking the fork button on the top of the page.
2. Push your changes to your forked repository.
3. Send a pull request with your changes back to this repo.

When you send the PR, GitHub actions will start building and testing your changes on all platforms and build the Windows installer.

Because this is a mirror, we will not merge your changes. To propose your changes to the R community, send an email to the r-devel mailing list and include a link (or copy) of the patch file of your PR. You can easily get the patch by appending .diff to the url of the pull request. For example pr#7 would be: https://github.com/r-devel/r-svn/pull/7.diff. You can also submit a description of your proposed change along with a patch to the R bug reporting system; see Bug Reporting in R for more details.

The build system

In the same way you can test patches, you can use pull requests to experiment with changes in the build matrix.

Build scripts for GitHub actions are always stored in the workflows directory. The build-svn.yaml file lists commands used to prepare the server and build R on each of the platforms. Here you can easily enable/disable features, or add another flavor to the mix.

Build locally

The examples directory contains scripts to show how to build R locally. Basically these scripts just let you run the same steps as the CI in build-svn.yaml for a given platform:

• build-r-macos.sh: do a full prep, build, and check on MacOS.
