Metaserver r63 patches over this a bit (when there are no players at all).

Tiny thing that's been bothering me for ages...

I've noticed that on http://meta.freeciv.org/ sometimes server show up as having "Human Players" = "Unknown", despite being a new enough version (post patch #2312) that they should know about humans. This has made me not quite trust that column at all.

Now I come to investigate, it happens when a server has no players at all (even AI), because in this case the server sends the special "dropplrs" signal to the metaserver and doesn't include the "humans" / "available" counts. So the metaserver can't know that this server counts humans.

Proposed backward-compatible solution:

  • In the server, always send "humans" (and maybe "available") even if there are no players and we're sending "dropplrs". (I think old metaservers will ignore this.)
  • In the metaserver, if the incoming request from a server includes "humans" (and maybe "available"?), honour it (or at least set "humans" to 0 rather than -1). (Old servers will give the current behaviour.)
