good hint, although would not serve us as a workaround but rather possibly
reveals the actual problem if ran in interactive mode (if I pipe the output --
the same error)...
the original error happens in the code which reacts to unsuccessful execution
of GdbDebuggerTestCaseand apparently has a problem with that unicode string
(although it was decoded from UTF-8 without errors). To say the truth, unicode
handling philosophical understanding is not my strongest skill, BUT it seems to
spit out the actual error without failing if I explicitly encode that errmsg
back into UTF-8 and write that. Alternative more generic implementation there
could be get a custom writer for stderr:
class TestAll(GdbDebuggerTestCase):
def test_all(self):
if not test_gdb():
return
out, err = self.p.communicate()
err = err.decode('UTF-8')
exit_status = self.p.returncode
import codecs
stderr = codecs.getwriter('utf8')(sys.stderr)
if exit_status == 1:
stderr.write(err)
elif exit_status >= 2:
border = u'*' * 30
start = u'%s v INSIDE GDB v %s' % (border, border)
end = u'%s ^ INSIDE GDB ^ %s' % (border, border)
errmsg = u'\n%s\n%s%s' % (start, err, end)
stderr.write(errmsg)
With such code it spits out errmsg reliably:
