[logback-user] ?????? maxIndex issue

Wed, 17 Jun 2020 23:35:10 -0700 

The max index can not greater than 20, hardcode, 
in FixedWindowRollingPolicy.java



    /**
     * It's almost always a bad idea to have a large window 
size, say over 20.
     */
    private static int MAX_WINDOW_SIZE = 20;

Hi all,

I have my rollingFileAppender configured as follows:


appender("myAppender", RollingFileAppender) {
&nbsp; &nbsp; &nbsp; &nbsp; file = "${logDir}/myApp.log"
&nbsp; &nbsp; &nbsp; &nbsp; encoder(PatternLayoutEncoder) {
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; charset = Charset.forName('UTF-8')
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; pattern = log_pattern
&nbsp; &nbsp; &nbsp; &nbsp; }
&nbsp; &nbsp; &nbsp; &nbsp; rollingPolicy(FixedWindowRollingPolicy) {
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; fileNamePattern = 
"${logDir}/myApp%i.log"
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; minIndex = 1
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; maxIndex = 24
&nbsp; &nbsp; &nbsp; &nbsp; }
&nbsp; &nbsp; &nbsp; &nbsp; triggeringPolicy(SizeBasedTriggeringPolicy) {
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; maxFileSize = 
FileSize.valueOf("200KB") &nbsp; &nbsp; &nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; }
&nbsp; &nbsp; }



I had first the&nbsp;maxIndex = 20, i modified it to 24 and I'm testing. As I 
see the number of logs are 21 and rotating while it should be 24! I tested it a 
lot and still the same issue. Anybody has this issue before or knows why this 
is happening?


Thanks in advance,
Joud
