Stack Traces

Depending on how the program was compiled, PGOPHER may produce a stack trace.

Under Microsoft Windows, this will be saved to a "pgopher.log" file. A popup box will indicate the location of this file, which is normally in the same directory as the executable or the data file (depending on which is writeable). An entry is added to this file for each crash. If the program hangs Process Explorer may be able to create a stack trace (Right click on PGOPHER in process explorer, select "Threads" and "Stack").

On Linux systems, the trace will appear in PGOPHER's log window, or on the console. If the program hangs rather than crashes the following can be used to force the generation of a stack trace. The first step is to find the process ID; the system monitor application can be used to find this, or alternatively in a terminal window type the following:
ps ux | grep pgopher
which will produce an output looking something like this:
usera     5141  0.1  0.1 1730940 42856 pts/3   Sl   13:08   0:00 pgopher
usera 5234 0.0 0.0 118492 896 pts/3 S+ 13:10 0:00 grep --color=auto pgopher
The first line here shows the PGOPHER process, for which we require the process ID, which is the first number on the line - here 5141. Use this number in the kill command:
kill -SEGV 5141
On Macs the trace will appear in PGOPHER's log window, or on the console. If you see a (system generated) "Report Problem" dialog the call stack is visible if you click on the "Show Details" button. If the program hangs, rather then crashing a stack trace can be generated using the "Activity Monitor" app that is present in all Macs - look in the utilities folder. After starting the Activity Monitor, click on the row showing PGOPHER, select "View", "Inspect Process" and click on the "Sample" button.
