Re: [libvirt] [PATCH] xenapi: Improve error reporting in xenapiOpen once again

privP->session->error_description is a list and in order to get the complete error message all parts of the list should be concatenated. xenapiSessionErrorHandler does this when its third parameter is NULL. The current code discards all but the first part of the error message resulting in a potentially incomplete error message. This partly reverts 006be75ee214f9b4, that tried to avoid reporting a (null) in the error message. The actual problem is more general in returnErrorFromSession that might return NULL if there is no error. Make sure that returnErrorFromSession return non-NULL always. Also don't skip the last error message part. --- src/xenapi/xenapi_driver.c | 5 +---- src/xenapi/xenapi_utils.c | 4 +++- 2 files changed, 4 insertions(+), 5 deletions(-)
