Denis, could you run some tracing (an example of EOF when it works and an example of EOF when it doesn't).  http://wiki.eclipse.org/Platform_Command_Framework#Tracing_Option

commandId = org.eclipse.debug.ui.commands.eof

Specify the commandId to get specific eof command information.

Thanx Denis,

From your trace where EOF didn't work, it still looks like we're executing the handlers:

HANDLERS >>> Command('org.eclipse.debug.ui.commands.eof') has changed to 'org.eclipse.debug.internal.ui.views.console.ProcessConsolePageParticipant$EOFHandler@1770bec' as its handler
KEYS >>> Listener.handleEvent(type = KeyDown, stateMask = 0x0, keyCode = 0x30, time = 23555078, character = 0x30)
KEYS >>> WorkbenchKeyboard.press(potentialKeyStrokes = [0])
KEYS >>> Listener.handleEvent(type = Traverse, stateMask = 0x0, keyCode = 0xd, time = 23555796, character = 0xd)
KEYS >>> WorkbenchKeyboard.press(potentialKeyStrokes = [CR])
KEYS >>> Listener.handleEvent(type = KeyDown, stateMask = 0x0, keyCode = 0xd, time = 23555796, character = 0xd)
KEYS >>> WorkbenchKeyboard.press(potentialKeyStrokes = [CR])
KEYS >>> Listener.handleEvent(type = KeyDown, stateMask = 0x0, keyCode = 0x40000, time = 23556031, character = 0x0)
KEYS >>> Listener.handleEvent(type = KeyDown, stateMask = 0x40000, keyCode = 0x7a, time = 23556578, character = 0x1a)
KEYS >>> WorkbenchKeyboard.press(potentialKeyStrokes = [CTRL+Z])
KEYS >>> WorkbenchKeyboard.executeCommand(commandId = 'org.eclipse.debug.ui.commands.eof', parameters = {})

I've passed this onto Debug to comment.

It looks like the handler is set correctly and we're executing the command.  But the symptom is this works in Run mode but not in Debug.

Works for me in run and debug mode using the Eclipse SDK and Java debugger. Moving to CDT for comment.

Comment 6 Denis Nedelyaev 2009-09-25 04:42:59 EDT

I tried following on Linux. (Eclipse IDE for C/C++ Developers, Build id: 20090619-0625)

The program's source code is:

#include <stdio.h>
int main() {
   int n;
   while (scanf("%d", &n) != EOF) {
      printf("echo: %d\n", n);
      fflush(stdout);
   }
   printf("end of input\n");
   fflush(stdout);
}

After launching the program in a Linux terminal, I can enter:

1<ENTER>
2<ETRER>
3<ENTER>
<CTRL+D>

to get this:

echo: 1
echo: 2
echo: 3
end of input

But if I enter the same in Eclipse, then it output just this:

echo: 1
echo: 2
echo: 3

There is no "end of input". And when I enter new numbers, it doesn't echoes.

Seems that it stops send new input to the program but not sends EOF.

So the Linux port have same problem. And it doesn't work even in Run mode (not only in Debug).

Is a duplicate of bug #159803

Comment 8 Matias Giangualano 2020-03-24 11:35:11 EDT

There is the same problem in Eclipse MARS 3.2 on Windows 8 and Java SE.

In Debugging Perspective, the console does not recognize EOF signal (ctrl + z).

Here it is my workaround:

change perspective and then focus by clicking on another form.

After that go back to debug perspective and then click to the console form.

Now press crtl + z (EOF on Windows) and it should catch the right input
