TypeError when empty xml elements in response #512
Description
When response is like:
<response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="https://xdebug.org/dbgp/xdebug" command="feature_get" transaction_id="6" feature_name="supports_async" supported="1"/>
this code (https://github.com/vim-vdebug/vdebug/blob/master/python3/vdebug/session.py#L260 ) in must_features and maybe_features can lead to error as feature_value will be NoneType (274):
for feature in maybe_features:
try:
feature_value = self.__api.feature_get(feature)
log.Log(
"Maybe Feature: %s = %s" % (feature, str(feature_value)),
log.Logger.DEBUG
)
except dbgp.DBGPError:
error_str = "Failed to get feature %s" % feature
log.Log(error_str, log.Logger.DEBUG)
So we need to be sure that response (xml)text is a string.
