eval.php previously set $wgDebugLogFile to /dev/stdout. This had the following problems: * It doesn't work if the maintenance script is executed via sudo, since /dev/stdout is typically owned by the original user, so MW can't open it. Using php://stdout worked on HHVM but not PHP. * Setting $wgDebugLogFile has no effect if the wiki uses MonologSpi. * Setting $wgDebugLogFile has no effect on channels configured with $wgDebugLogGroups. * stderr is a more appropriate place to send logging output. * Writing to configuration variables is discouraged. So, add ConsoleSpi, which is a very simple logging service provider which sends all messages to stderr. This should be suitable for debugging with eval.php or shell.php in WMF production or beta.
