RE: DateFormatFileAppender

[James Stauffer <js...@spscommerce.com>]

1. Sending to correct list now.  Sorry.
2. DateFormatFileAppender is different than DailyRollingFileAppender as far
as I can tell.  I couldn't get DailyRollingFileAppender to put the file in a
subdirectory based on the date.  Looking at the code it doesn't look like
subdirectories in the pattern are supported.  The other difference is that
DailyRollingFileAppender has the current logs always in the same file (the
old logs are named based on date).  DateFormatFileAppender names the current
file based on the date.
   Sample File: 'logs/'yyyy/MM-MMM/dd-EEE/HH-mm-ss-S'.log'
   Makes a file like: logs/2004/04-Apr/13-Tue/09-45-15-937.log

I have also changed the code so that it takes an option "Separate" so that
each log is in a separate file (and the File option is re-evaluated each
time).  This is useful when logging errors with stack traces.  I can provide
more information if anyone thinks that might be good to add to log4j.
Either way it is working well for us so far.  I attached the current code
but it is in a package from our code right now (easy to change).

Hi,
1. This already exists (DailyRollingFileAppender in log4j 1.2 and various
options in log4j 1.3),
2. This is the wrong list: log4j-user is the place.

I posted a message to the user list titled "Logs separated by
year/mon/day."  It doesn't look like any current appenders support what I am
trying to do so I wrote a new appender (attached).  It works but probably
needs to be cleaned up (formatting, etc) to fit in log4j.  (The only change
I made after my last run with it was to change the package.)  I also
don't know if I did things the "preferred" way.  It is a simple class.  It
just overrides setFile(String, boolean, bufferedIO, bufferSize) to format
the given fileName and produce another fileName (producing directories as
necessary).  Is this something that you would be interested in having in
log4j?  If yes, I can clean it up more and follow any advice you have.  I
tried bugzilla but it appears to be down right now.  Questions and comments
are welcome.
