  18 # todo:
  19 # fix weird characters (see erica's song)
  20 # use shutil.copyfileobj to possibly speed up copying
  21 # - check if it actually causes chunked reads from the browser
  22 # support multiple files
  23 # - daemonize replaygain?
  24 # track uploads
  25 # - phone ip is hopefully good enough
  26 # - track # of uses of asap/Next Please
  27 # - track files we have queued (need at least next-please so we can queue those in order)
  28 # integrate better with native queue

  31 ## crazy idea: if the playlist can be watched with a script... (maybe
  32 ## a json rpc notification? but ... reliability, and upload.cgi runs
  33 ## infrequently enough that it cannot record the playlist and extract
  34 ## a meaningful image of the queue ...).
  35
  36 # diff playlist whenever item is inserted (or song changes, or whatever we can hook on).
  37 # scan for common items (discarding the head of the old snapshot, since we could just be advancing)
  38 # when the first different item is found... if it ain't the end of the list it's been queued
  39 # keep going until we match up again and record the end of the queue position in a file
  40 # what about when we delete in the list?
  41 #
  42
  43 # upload.html
  44 # - show playlist length, # of next/asap available, likely queue position
  45 # - show upcoming songs (5? just next-please?)
  46 # - - just use SSI + python virtual includes, seriously
