internal package Foswiki::Logger::Compatibility is a Foswiki::Logger

Compatibility with old LocalSite.cfg settings, if user has not run configure yet. This logger is automatically used if Foswiki senses that the LocalSite.cfg hasn't been modified for 1.1 (configure has not been run yet). It may also be explicitly selected in configure.

Plain file implementation of the Foswiki Logger interface. Mostly compatible with Foswiki 1.0.0 log files, except that dates are recorded using ISO format, and include the time, and it dies when a log can't be written (rather than printing a warning).

This logger implementation maps groups of levels to a single logfile, viz.

• debug messages are output to $Foswiki::cfg{DebugFileName}
• info messages are output to $Foswiki::cfg{LogFileName}
• warning, error, critical, alert, emergency messages are output to $Foswiki::cfg{WarningFileName}.
• error, critical, alert, and emergency messages are also written to standard error (the webserver log file, usually)

This is a copy of the Foswiki 1.0 code.

ObjectMethod log($level, @fields)

See Foswiki::Logger for the interface.

StaticMethod eachEventSince($time, $level) → $iterator

See Foswiki::Logger for the interface.

This logger implementation maps groups of levels to a single logfile, viz.

• info messages are output together.
• warning, error, critical, alert, emergency messages are output together.
• $version - Version 1 of API returns a hash instead of an array.
• $lock - boolean switch to enable locking, off by default
