#ifdef ERROR

// SOMEDAY: Split this into flow, fdbclient, fdbserver error headers?

// Error codes defined here are primarily for programmatic use, not debugging: a separate
// error should be defined if and only if there is a sensible situation in which code could
// catch and react specifically to that error.  So for example there is only one
// internal_error code even though there are a huge number of internal errors; extra
// information is logged in the trace file.

//   the way operations are currently defined)
