Cloud & SaaS hosting

We have inbuilt support for the kind of advanced features needed for scaling Composr installations.

For Developers

Git read access

Git is the revision control system we use to collaborate on Composr.

You can access the repository on Github.

We often commit fixes to Git before patch releases come out.

Be aware that the Git repository also has all the ocProducts addons in it. We develop them in there, to keep them up-to-date. There is a script called delete_alien_files.php which will erase them. You need to first delete the sources_custom/hooks/systems/addon_registry/*.php files of any addons you don't want, then run the script, then run the commands the script says (after reviewing), then install.

Git write access

Composr development is sponsored and led by ocProducts, who is the primary developer. However we do accept and encourage external contributions. Composr is a community project after all, even if we do centrally ensure its quality.

We will provide write-access to Git as appropriate (essentially when someone shows a serious commitment to the project in the form of high-quality code).
