Subversion is a version control system used by ReactOS to manage the source code of the project.
ReactOS source code was in a CVS repository up to December 30th 2004. Since January 1st 2005, the source code is in a Subversion (SVN) repository.
As of May 2014, ReactOS is using Tigris SVN (now Apache SVN) version 1.6.17. ReactOS also uses ViewVC or web viewing, which is usually up to date.
Source Code Locations
The Operating System itself with base components
Additional applications for ReactOS (bundled with releases)
ReactOS Press Media
Graphical media used for representing the project
ReactOS Project Tools
Additional tools used inside the ReactOS Project
Website components of the ReactOS Project
- ReactOS Documentation – Some documentation of ReactOS components (very old)
- ReactOS Wallpaper – Wallpapers used in ReactOS Releases
These locations are just temporary and the code is usually merged back into the official source code after it has been improved.
For Windows, it is recommended to use the TortoiseSVN client, which nicely integrates into the Windows Explorer. There is also a subversion command-line interface bundled with the ReactOS Build Environment for Windows.
The usage of these clients is described in a separate article for each client:
Commits are data added to the ReactOS SVN. The term data is used because it is not limited to code, but may include any other media including icons and sound. If a piece of code is committed then it means that its part of the ReactOS source code. Every commit has its own unique identification number and a message explaining its purpose.
In an effort to lessen the load when changelogs need to be written for releases, this is the proposed commit message format. The general idea is that a script can be run from one SVN revision to another and populate the changelog by putting all commits for one component into a single category. To do this, a commit needs to identify which component(s) it is for.
[Component Name] -Description of change.
[KERNEL32] * Don't access freed memory in GetVolumeNameForVolumeMountPointW
When commits are made, it makes notifications is several ways.
- Mails with changes in each commit are sent to the mailing list ros-diffs. They will be plain text mails, which contain the differences in this revision.
- The RosKGB IRC bot in #reactos notifies the room of the event
- The ReactOS FishEye webinterface also shows the message of all the last commits.
Request commit (write) access
There are a few mandatory prerequisites to getting a direct, full write access (aka "commit access") to the main repository:
- Ability to communicate in written English.
- Be ready to disclose a full real name to at least the project's official (e.g. development lead or project lead), and preferably disclose full real name for public access.
- Have no legal restrictions related to contributing code to open source projects. Employees of Microsoft and subsidiaries are not allowed to work in the project.
Applying for write access
Once you have started submitting patches and new code to the project you can be considered for application. We would prefer not to give access to someone who makes two or three updates and then never again. Also, if you are only going to submit patches now and again, you should file a bug in our JIRA and attach the patch file to it. If, however, you become a contributing developer on a continuing basis, you should definitely consider applying for write access.
Who to ask

SVN Update says: Object with the same name already exists
When you update your working copy, you may get the error message object with the same name already exists.
Subversion displays the error message because the directory is replaced in the repository and your working copy contains data which is unknown to Subversion (Your working copy is locally modified). Since Subversion does everything it can to not cause harm to your data, you must remove or move the data which is not in the repository out of the working copy.
This scenario won't happen very often though. You have two options to correctly resolve the problem:
- Remove the affected directory and update your working copy again.
- Remove all files and directories in the working copy that are unknown to Subversion and then update your working copy again.
