The new problem should be fixed [1]. If necessary, please submit new
issues in GitHub.

Thanks for the test case. That's helpful.

While similar, this problem is actually different from the first.
Originally, the layout pattern couldn't be parsed. With that problem
fixed, the parser now trips up on the input line. It sounds like the
logger-name parser is using a greedy regex matcher (similar to the
problem with the layout pattern). I'll look into this tonight.

I so I picked up your latest

Does not work for me

Test case:

2013-06-12 15:27:15.044 INFO  [main] KdbFxFeedhandlerApp: Running
com.ubs.sprint.kdb.fx.feedhandler.server.KdbFxFeedhandlerApp from
directory: /sbclocal/sprint/kdb-fx-feedhandler/0.0.23/bin/.\n

Pattern:

%d{yyyy-MM-dd HH:mm:ss.SSS,UTC} %-5level [%thread] %logger{0}: %msg%n

Logger name now seems to consume the message up to the 2nd colon. One
would have hoped it would stop at the first colon.

Michael

Note I added the two simple parsers like MessageParser to capture logger
and thread into the Log event

Hi Michael,

logback-decoder is definitely open to volunteers :)  not abandoned.

I've fixed the bug you've discovered [1]. Let me know if that works for
you.

Thanks,

Tony

Hi,

I'm trying to use this component - aware that it is in early dev stages
but with the intention of contributing back fixes.

For example I have made some changes to allow handling of date patterns
with a timezone e..g

%d{yyyy-MM-dd HH:mm:ss.SSS,UTC}

I have also added parsers for %thread and %logger.

I'm coming unstuck with a few types of pattern e.g.

%d{yyyy-MM-dd HH:mm:ss.SSS  %-5logger %msg

Will parse 

"2013-06-07 10:00:00.999 ERROR rest of my log message"

But will fail to parse  

"2013-06-07 10:00:00.999 INFO  rest of my log message"

(reducing the two spaces after INFO to one makes it parseable)

And also anything like %logger{0} seems to confuse matching no end. IN
debug mode it looks like the date pattern is considered to be the whole
pattern and it fails to see the } at the end of %d{....}:

08:46:01.510 [main] DEBUG ch.qos.logback.decoder.Decoder - date =
2013-06-07 05:03:28.853

08:46:01.514 [main] ERROR ch.qos.logback.decoder.DateParser -
java.lang.IllegalArgumentException: Illegal pattern character 'U'

08:46:01.514 [main] DEBUG ch.qos.logback.decoder.Decoder - level = INFO

08:46:01.515 [main] DEBUG ch.qos.logback.decoder.Decoder - BUG!! Saw a
field name that did not match the pattern info's name! (index=1

08:46:01.515 [main] DEBUG ch.qos.logback.decoder.Decoder - thread = main

08:46:01.515 [main] DEBUG ch.qos.logback.decoder.Decoder - BUG!! Saw a
field name that did not match the pattern info's name! (index=2
expected=thread actual=n)

08:46:01.516 [main] DEBUG ch.qos.logback.decoder.Decoder - logger =

java.lang.IndexOutOfBoundsException: Index: 3, Size: 3

     at java.util.LinkedList.checkElementIndex(LinkedList.java:553)

     at java.util.LinkedList.get(LinkedList.java:474)

     :

Remove the {0} from the end of logger and it all works.

Can anyone advise on how these last two could be fixed?

Also is logback-decoder abandoned or just waiting for volunteers?

If its abandoned are there any alternatives?

Regards,

Michael
