Some notes on features under discussion or consideration, and some vague implementation thoughts: * Add some kind of filter for "the directory we care about" - pseudo operations would only go to the server for items in this directory - optionally, logging could be generated for accesses *outside* this directory - intent is to reduce server load dramatically, and improve and/or streamline the logging path when, e.g., doing host contamination checking - probably implies a new message type, MSG_LOG. * Database recovery/reconstruction - capability for failing harder in the event of apparent corruption * Log database performance improvements - some way to do "live" queries against the log database while the server is running - some way to flush unwanted data - possibly a way to separate logging into multiple files or otherwise restrict the amount of stuff produced - logging filters of some sort * Canonicalization speedups - possibly implement some kind of cache of directory names and known canonicalizations * Possibly limited handling for extended attributes - specifically, the case where they're used to manpulate or query the plain old modes ala chmod/stat. * Test cases - boy, do we need test cases! * Clean up *at() functions - The *at() function implementations are gratuitously complicated, I believe because they predate the auto-canonicalization that came with the rewritten pseudo wrappers.
