(Updated Dec. 8, 2014, 11:57 a.m.) Review request for Aurora, Maxim Khutornenko and Bill Farner. Changes ------- Updated testing to show new log format. Bugs: AURORA-919 https://issues.apache.org/jira/browse/AURORA-919 Repository: aurora Description ------- This patch makes multiple changes to simplify the logging done in the Aurora client: 1. Remove the TRANSCRIPT log level and replaced all instances with the standard Python DEBUG level. 2. Remove the custom "aurora_client" logger. This logger was designed to give each invocation of the client a unique id and record the username of the user with the intention that a hook could take this information and ship it to the cluster administer. However a hook could capture logs by adding a handler to the root log handler and generate a unique id itself. 3. Remove the 'print_log' method of the context and replaced all callers with the standard python logging facilities. 4. Removed duplicate printing/logging messages by just printing the information to the user. 5. Removed the custom PlainFormatter implementation and replaced it with Python's default formatter. 6. Replaced the "--verbose-logging" and "--logging-level" flags with a single "--verbose/-v" flag which enables DEBUG logging. Without this flag the user sees INFO and up.
