| - | Developer playgrounds should be able to build the ''main'' branch. It is okay to use ''./install-deps.sh'' top-level scrip from the ceph source tree to update dependencies. Do not run that script from an older release of Ceph as it may break other developer's work. If you need to build an older release, lock a throwaway node like [[hardware:smithi]] and build there. Or, use a container to do the build/testing! | + | Developer playgrounds should be able to build the ''main'' branch.

| Using the developer machines to look at teuthology QA artifacts is encouraged. Try to avoid using a text editor to look at large (1GB+) debug logs as this can be RAM intensive/disruptive. Instead, prefer ''less'' or use ''tail -c xM | $EDITOR -'' to look at portions of the log in a text editor. | Using the developer machines to look at teuthology QA artifacts is encouraged.
