subtable entry expiry

We're starting to get into implementation details now, rather than "the way it's defined to work", but it's checked on every direct access.

 

 

I still get the feeling we're talking past each other a little. Here's some code to demonstrate what I mean:

 

 

   when CLIENT_ACCEPTED {
      table set key value 1
      set i 0
      while { $i < 20 } {
         set value [table lookup -notouch key]
         set time [clock clicks]
         set sec [string range $time 0 end-6]
         set msec [string range $time end-5 end]
         TCP::respond "At time $sec.$msec, value is $value\n"
         after 100
         incr i
      }
      TCP::close
   }

 

 

And here's the output:

The entry was added at 1351212932 with a 1 second timeout, so when the current time minus 1351212932 exceeds 1, the entry gets expired. So an entry with a 1 second timeout is removed anywhere between 1 and 1.999999 seconds after it was added, depending on where in the second it was added.
