Websocket terminal output not shown until next input

[EnricoParisi]

Type: Bug

In Websocket terminal if you run some code that perform Read commands on other devices (i.e. not on terminal itself), then the output (any write to terminal) in not displayed until, after the execution of the code, enter is pressed.

To reproduce the problem, create use a (relatively) big txt file, around 5MB or more (it should take a little while to read it) and run this oneliner from Websocket terminal:

Set file="c:\temp\anytext.log" Open file:"R" Use file Try {For {Read Line}} Catch {Close file} Use 0 Write "Done",!

When it finishes nothing is displayed and you get the prompt. If you press enter at the prompt, then "Done" is written in the terminal.

The problem is server side in %Atelier.v7.TerminalAgent.cls, when check if the debug process is stil running or is reading from terminal in the line:

If (((tState = "EVTW") && (tStopped = 1)) || ($EXTRACT(tState,1,4) = "READ")) {

In addition to test if the process in in READ* state, it should check that the read is performed on the terminal (the debug device), so it should be:

If (((tState = "EVTW") && (tStopped = 1)) || (($EXTRACT(tState,1,4) = "READ") && ($SYSTEM.Process.CurrentDevice(..Debug.Pid) = ..Debug.Dev))) {

This feature is implemented by the ObjectScript extension, not Server Manager, so I have transferred the issue.

@EnricoParisi Thanks for reporting this. Since the bug is in ISC code I will close this and fix it internally.
