libUrl tsNet and socketTimeoutInterval

Hi Ralph,

You are correct, as tsNet does not use the standard LiveCode sockets, it does not pay attention to the socketTimeoutInterval.

However, rather than disabling tsNet, you can resolve any app hangs related to socket timeouts by using the tsNetSetTimeouts command which allows you to control how long the external will wait before considering a connection lost.

Have a look at the following bug report which is about a similar issue:

Effectively the last two parameters to that command allow you to set a minimum amount of data that must be transferred across a connection within a specified period of time to consider a connection still active.

Having said that, when tsNet is disabled, libUrl should continue to pay attention to the socketTimeoutInterval property.

I have just done quick test on LC8.2.0dp2 and if I set the socketTimeoutInterval before making a “put URL xxx” call to a script that deliberately doesn’t respond in time, the request times out after the time specified by the socketTimeoutInterval call and returns a result of “socket timeout”.

I seems that when tsNet was included in v8 the property socketTimeoutInterval does nothing when doing ==> put url("https://"&pURL&":"&pPort) into tWebData <==. This explains a few reported app hangs. In the IDE tried ==> dispatch "revUnloadLibrary" to stack "tsNetLibURL" <== but socketTimeoutInterval still does nothing. Ran the stack in 7.1.4 and socketTimeoutInterval works as expected. It's my understanding that when tsNet is unloaded libUrl falls back to using sockets and the socketTimeoutInterval property should be respected.
