Hello Ralph


Thanks. But yes tsnet was initialized.

I’ve measured the timeouts in miliseconds and it was always 30003 milliseconds.
But it’s only when there is a connection but there isn't enough network 
capacity for data transfer (so it’s difficult to test ! This can happen in the 
mountains, far from mobile antennas, or on the edge of wifi coverage.

Re: Check connection and timeout

2023-07-14 Thread Bob Sneidar via use-livecode

Hi Ludovic. 

I use a simple method of sockets to determine if I have a connection to a host. 
I close the socket first: 

closeSocket 127.0.0.1:3306

Then I open the socket:

Open socket to 127.0.0.1:3306
Put the result into tError

If terror begins with “ERROR: “ then
   — your code here
End if

Then close the socket again. 

Close socket 127.0.0.1:3306

I find this to be the most reliable way to check a connection. I may not have 
internet, but the host may not be on the internet it may be local. Also, 
sockets will always work whereas ICMP can be blocked by a firewall. And simply 
trying to connect to a host will, as you have noticed bring timeouts into play.

RE: Check connection and timeout

Bob,

I use this function to return an array of the timeouts.

function EIStsNetGetTimeouts
   local tTimeouts, tTsNetTimeoutArray
   put tsNetGetTimeouts() into tTimeouts
   put item 1 of tTimeouts into tTsNetTimeoutArray["DnsCacheTimeout"]
   put item 2 of tTimeouts into tTsNetTimeoutArray["RequestTimeoutMS"]
   put item 3 of tTimeouts into tTsNetTimeoutArray["ConnectTimeoutMS"]
   put item 4 of tTimeouts into tTsNetTimeoutArray["AcceptTimeoutMS"]
   put item 5 of tTimeouts into tTsNetTimeoutArray["LowSpeedTime"]
   put item 6 of tTimeouts into tTsNetTimeoutArray["LowSpeedLimit"]
   return tTsNetTimeoutArray
end EIStsNetGetTimeouts

Thanks Ralph, very handy, but is there a way to get the timeout to see if
the command to set the timeout worked? I change networks frequently, and if
I do not disconnect and reconnect to my SQL database, I run the risk of
using a stale connection, and then I face the dreaded 60 second stall before
I can proceed.

Ludovic,

Make sure that tsNet is active:

command NetworkType
   if GetNetworkType() = "libURL" then
  answer"tsNet is disabled(LibURL)"
   else
  answer "tsNet in use"&"Version==>"& tsNetVersion()
   end if
end NetworkType

Did you initialize tsNet? ==> tsNetInit

Disable tsNet ==> dispatch "revunloadlibrary" to stack "tsnetliburl"
To enable tsNet ==> dispatch "revloadlibrary" to stack "tsnetliburl"
