How to set SOCKET:CONNECT() timeout value

Even in other languages this appears to be tricky.

One way is to use another thread (no option in ABL), the other is to ping and if that succeeds try to connect (although ping just checks the availability of the host, not the port...)

bytes.com/.../476331-connect-socket-timeout

can be done from a lower level, think had something like 'test service' in this little socket project have had a long time ago sourceforge.net/.../pro_sock

I think there a way to set timeout value in SOCKET:CONNECT() method, using "-clientConnectTimeout" parameter, it takes value in milli seconds. Basically this sets socket level timeout value in client side socket.

By default connect is blocking in nature, setting client connection timeout value makes the connection request non-blocking, and returns will error if connect not successful with in the given time interval.

Thanks to both, I just got a reply from tech support mentioning the -clientConnectTimeout parameter too:

There is an undocumented parameter for the CONNECT method which is "-clientConnectTimeout <n>". It needs to be added as part of the connection string. <n> is the number of milliseconds to wait before timing out the connection attempt.

This parameter was introduced for SSL connections in OpenEdge 10.2B07 or OpenEdge 11.2.0 or later. Support for non-SSL connections was added in OpenEdge 11.3. Please note that since OpenEdge 11, two connection attempts are made before the connection attempt is aborted. So please keep this in mind when calculating your timeout.

nice explanation, would it be too hard to have it documented? even if it
was in some release notes not everyone is actually reading those :)

That's great information, thanks ☺
Now, let's all go and upgrade to 11.3 and start using it. whoHoo!

Please let us know if this works for you. I will then report this to our documentation team, because obviously it should be present in our documentation.

So I assume this should go in the docs for a next release...
