- Update master before starting on a new bug (and run make check to confirm it compiles cleanly before you make any changes).
- Do not submit patches that depend on each other, unless being told to do so. Doing so will make your patch incapable of being merged.
- If your patch is not ready to be merged, assign -2 to it, that way reviewers know it is Work In Progress.
- Patience is a key, reviewing takes time and we are all volunteers, so expect a couple of days to pass.
