Hi,

In the below data structures, is there any way to make &mergeable apply to  
the set[port]s? If I make empty\_smtp\_servers &mergeable, I get an error. If  
I make data &mergeable, will it propagate all the way down to the  
smtp\_servers tables?

type SMTPServers: table[addr] of set[port];

const empty\_set\_of\_ports: set[port] = {};

const empty\_smtp\_servers: SMTPServers = table()  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&default=copy(empty\_set\_of\_ports)  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&write\_expire=too\_many\_smtp\_servers\_expire;

type HostData: record {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;## SMTP servers the host has successfully connected to.  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;smtp\_servers: SMTPServers &default=copy(empty\_smtp\_servers);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...  
};

global data: table[addr] of HostData = {}  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&default=[]  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&synchronized  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&persistent;

Just to be clear, what I want is the below two lines--run simultaneously  
on two nodes--to result in data[192.0.2.1]$smtp\_servers[192.0.2.2]  
containing both 25/tcp and 587/tcp.

add data[192.0.2.1]$smtp\_servers[192.0.2.2][25/tcp];  
add data[192.0.2.1]$smtp\_servers[192.0.2.2][587/tcp];
