Subject: selftest/gdb_backtrace: print python traceback if available
X-Git-Tag: tdb-1.4.11~1416
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=904479cdf6d58142baa012a7b588fca857f275f4;p=thirdparty%2Fsamba.git

selftest/gdb_backtrace: print python traceback if available

If a program happens to have 'PyList_New' defined but is not a python
script, gdb will print

> Undefined command: "py-bt".  Try "help".

and probably stop. This happens after the C backtraces have been
printed, so nothing is lost.

The traceback is printed twice -- once in conventional Python style
for clarity, and once with extra "full" information.
