New GlusterFS Translator-API Guide

I wrote up a new version both because we need it internally for new CloudFS developers and because others have asked. It’s about 50% longer than the old version, and would probably be twice as long if I hadn’t deleted the section describing the details of the call_frame_t structure (which just doesn’t seem that useful). Topics covered include:

  • Introduction
  • Dispatch Tables and Default Functions
  • Per Request Context
  • Inode and File Descriptor Context
  • Dictionaries and Translator Options
  • Logging
  • Child Enumeration and Fan Out

Let me know if there are any significant subject areas I missed, or if there are errors.
