Spoolfetch repository format proposal

Format of the storing directory for the spoolfetch implementation. Its design is based on ideas borrowed from Subversion's server storage system.

  • There is the file ${spooldir}/README.txt that explains the content of the spooldir directory. It is created when creating the spooldir, and unchanged after.
  • A config file ${spooldir}/format that stores versioning & configuration informations for the spooldir.
  • The config is stored in the file ${spooldir}/${node}/${plugin}.config
  • The values are stored in the file ${spooldir}/${node}/${plugin}.${epoch_mod_N}.data

The ${epoch_mod_N} is the epoch modulo N. It permits to limit inode consumption, while still being able to avoid locking (append-only whole lines), ease cleanup (old files may be pruned easily) & indexed epoch access (just open the correct file and filter it line per line on the epoch stored in it).
