JWT007 opened a new issue, #3086: URL: https://github.com/apache/logging-log4j2/issues/3086
In the Log4j 2.x documentation for the RegexFilter: https://logging.apache.org/log4j/2.x/manual/filters.html#RegexFilter The only two configuration attributes are "regex" and "useRawMsg" (and the common filter attributes onMatch/onMismatch). In the RegExFilter @PluginFactory there is a nested element for a set of Strings which is not mentioned in the documentation: ``` @PluginFactory public static RegexFilter createFilter( // @formatter:off @PluginAttribute("regex") final String regex, @PluginElement("PatternFlags") final String[] patternFlags, @PluginAttribute("useRawMsg") final Boolean useRawMsg, @PluginAttribute("onMatch") final Result match, @PluginAttribute("onMismatch") final Result mismatch) // @formatter:on throws IllegalArgumentException, IllegalAccessException { ``` If I understand correctly one can provide field names from the Pattern class here: (CASE_INSENSITIVE, COMMENTS, etc.). The example in the Plugin Reference for the RegexFilter shows an example of nested strings but is not very clear with "a-String-implementation": ``` <RegexFilter onMatch="" onMismatch="" regex="" useRawMsg=""> <a-String-implementation/><!-- multiple occurrences allowed --> </RegexFilter> ``` Is it: ``` <RegexFilter ...> <CASE_INSENSITIVE> <COMMENTS> </RegexFilter> ``` which the plugin reference implies. Or: ``` <RegExFilter ...> <PatternFlags>CASE_INSENTIVE, COMMENTS</PatternFlags> </RegExFilter> ``` ? A usage example would be helpful. Maybe this API is not really "public"? In the log4j-core-test RegexFilter test it seems the RegexFilter is never tested with anything but a null value for the patternFlags. -- This is an automated message from the Apache Git Service.
