Server responses returning an error - "latched" because the curl_easy handles for error cases weren't all - systematically removed from the curl multi handle. This prevented - their proper re-addition the next time. - - This version of the code simplfies matters by making only the curl - curl_multi handle long-lived. This turns out to be enough, because it - can maintain a pool of long-lived http/https connections and related - data, and lend them out to short-lived curl_easy handles. This mode - handles errors or hung downloads even better, because the easy handles - don't undergo complex state transitions between reuse. - - A new test case confirms this correction via the federating debuginfod - instance (cleaning caches between subtests to make sure http* is being - used and reused). - - Signed-off-by: Frank Ch.
