Logging Enhancements (Revision #18)

The new Help Window now contains a log viewer and a console to assist in application troubleshooting. Now, instead of having to use the operating system’s console or terminal, users can view events as they happen in this new console, without leaving the application. The new Log Viewer records and accumulates entries logged only after opened from the Help Window.

Help window Log

• Filtered by log level.
• Intercepts stdout, stderr, and uncaught exceptions in the Console tab
• Contents of Log Viewer and Console can be copied to Clipboard.

- Help/View Log menu option invokes Log Viewer dialog which works independently of the normal log file.

Log Viewer dialog:

- starts with an empty log table

- accumulates entries logged after the dialog has been opened

- Save to Clipboard button

- allows to set filter by level

- intercepts stdout, stderr and uncaught exceptions in the "Console" tab

By default, a rolling file logger is always enabled to ~/.datastudio/datastudio.log

This logger is configured to write up to 3 files of up to 300KB each, using "%d{M/d HH:mm:ss.SSS} %C{1}.%M %m%n layout.  (Logging month/day per Tanya’s request).

This logger can be turned off by placing logger.config file into ~/.datastudio directory.  This file overrides built-in configuration and offers the developers or end users virtually unlimited configuration choices.
