Re: [cdt-dev] Thread Names in debugger

[Stefan Bylund <steby@xxxxxxx>]

Hi,

For some operating systems, the GDB "info threads" command will show 
extra information about the threads, e.g. name and ID. If that is the 
case, there is a hook in CDT for collecting that extra information and 
provide it to CDT. This hook is described in CDT feature request #69711 
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=69711) and has been 
implemented in CDT since CDT 2.0. We use it in our Eclipse/CDT based 
product.

This issue was discussed several years ago on the CDT mailing list:
http://dev.eclipse.org/mhonarc/lists/cdt-debug-dev/msg00462.html
http://dev.eclipse.org/mhonarc/lists/cdt-debug-dev/msg00463.html

If the native Linux GDB back-end does not provide extra information 
about thread names in the "info threads" command, this solution won't 
help you. Maybe that kind of functionality could be added to the native 
Linux GDB back-end?

I realize that if you just want to use Eclipse/CDT/GDB for debugging 
multi-threaded Linux programs you would want this feature 
out-of-the-box; you're not interested in extending CDT and possibly GDB 
to get this working. But if GDB can provide the required information, 
you could be a hero and contribute the required parts to get it working 
in CDT as well :-)

Regards,
Stefan
