[Bug general/6001] New: fcatch bogus output

[tromey at redhat dot com]

I ran fcatch 23867.  This seems to trace that PID.

This process forks and execs other processes.  Each time I get
pretty bogus output, like:

opsy. fcatch 23867
.updateForkedOffspring()
.updateForkedOffspring()
.updateForkedOffspring()
.updateForkedOffspring()
.updateForkedOffspring()
.updateForkedOffspring()


I assume this is a debugging printf.

I also get this:

21148.21148 terminated normally

... but I don't really want this, I just want notification of SEGVs.
Perhaps an option to change this would be nice.  Or maybe just roll
all the functionality of fcatch into ftrace.

[Bug general/6001] fcatch bogus output "terminated normally"

The first issue is indeed bogus debug output.
Removed:

commit 91c313424052de804959314bd179a5ade351da23
Author: Mark Wielaard <mwielaard@redhat.com>

    Removed debug output from ProcFollowUtil

    2008-03-31  Mark Wielaard  <mwielaard@redhat.com>
    
        * ProcFollowUtil.java (updateForkedOffspring): Remove debug output.

The second issue is deliberate:
frysk/util/FCatch.java

                // if the main thread exited print out a message that the process
                // terminated safely 
                if(task.getTid() == task.getProc().getPid()){
                    printWriter.println(task.getProc().getPid() + "."
                                + task.getTid() + " terminated normally");
                    printWriter.flush();
                }

I think it can be removed, or an extra option to print such informative
messages. And merging fcatch with ftrace might be an interesting option indeed.
