Document: Syslog4j CHANGELOG.txt
Version: $Id: CHANGELOG.txt,v 1.45 2009/07/25 18:43:22 cvs Exp $
URL: http://www.syslog4j.org/
--------------------------------------------------------------------------
Version 0.9.30 (07/25/2009)
+ Support added for "structured syslog" as defined here:
http://tools.ietf.org/html/draft-ietf-syslog-protocol-23
Code submitted by Manish Motwani (thanks, Manish!)
+ Renamed SyslogIF.fatal(..) methods to SyslogIF.emergency(..) to
be consistent with RFC 3164
+ Fixed copy/paste errors with SyslogIF.notice(..), SyslogIF.critical(..),
and SyslogIF.alert(..) levels
+ Fixed Log4jSyslogBackLogHandler.getLog4jLevel(..) to more
accurately convert syslog levels to Log4J levels
+ Set sendLocalName to false by default for UnixSocketSyslog
+ Improved UnixSyslog by using synchronization to support multiple
facilities by calling the static openlog(..) and closelog() methods as
necessary when the facility is "switched" between instances
(thanks, Ken!)
+ Added Syslog4jBackLogHandler which allows another Syslog4j protocol
to be used for back logging
+ JUnit test improvements; 77.5% instruction code coverage (EclEmma)
--------------------------------------------------------------------------
Version 0.9.29 (06/06/2009)
+ Added support for message truncation (instead of splitting messages
into more than one event) via SyslogConfigIF.setTruncateMessage(true)
+ Added more configuration options to Syslog4jAppenderSkeleton
+ Moved maxMessageLength to SyslogConfigIF
+ Set sendLocalName to false by default for UnixSyslog (credit: Nathan)
+ Removed unnecessary check for sub-zero length String in AbstractSyslog
(credit: Darien)
+ JUnit test improvements; 76.8% instruction code coverage (EclEmma)
--------------------------------------------------------------------------
Version 0.9.28 (06/03/2009)
+ Override added for UnixSyslog.prefixMessage(..) to remove support
for adding the "ident" value, which is redundant since Unix-based syslog
configures the ident within the openlog(..) method (thanks to Nathan)
+ Switched empty String in ident to a null before passing into openlog;
this substitutes the name of the running program for the ident field
--------------------------------------------------------------------------
Version 0.9.27 (04/16/2009)
+ Added main() methods to Syslog and SyslogServer for a rudimentary
command-line client/server implementations; coded in separate
SyslogMain and SyslogServerMain classes
+ Added notice(..), critical(..), and alert(..) methods to adhere
more completely with RFC 3164
+ SyslogServerEvent now parses incoming log data to determine level,
facility, date, and host
+ Several fixes to accommodate remote InetAddress information for
SyslogServerEvent
+ Added SyslogUtility.getLevel(String)
+ JUnit test improvements; 76.4% instruction code coverage (EclEmma)
--------------------------------------------------------------------------
Version 0.9.26 (03/29/2009)
+ Added SSLTCPNetSyslogServer and supporting classes for SSL/TLS
server support
+ Added keyStore, trustStore, keyStorePassword, and trustStorePassword
configuration options to SSL/TLS-related configuration classes
+ Refactored some configuration/method naming for consistency
+ JUnit test improvements; 76.0% instruction code coverage (EclEmma)
--------------------------------------------------------------------------
Version 0.9.25 (01/27/2009)
+ Removed delimiterSequence code from SyslogMessageProcessorIF,
SyslogMessageProcessor, AbstractSyslog, and all calling subclasses;
instead, a separate OutputStream.write(..) is called for the delimiter
+ Added a Socket.setSendBufferSize(..) call to TCPNetSyslogWriter;
this is combined with the delimiterSequence moved to a separate
OutputStream.write(..) call solves a problem where a single message
was lost every time a connection failure occurred between Syslog4j
and a syslog TCP server
+ Added more configuration properties to TCPNetSyslogConfig[IF] to
remove hard-coded values
+ JUnit test improvements; 75.1% instruction code coverage (EclEmma)
--------------------------------------------------------------------------
Version 0.9.24 (01/24/2009)
+ Fixes to AbstractSyslog and TCPNetSyslogWriter to properly handle
when TCP-based Syslog servers stop accepting connections and
then resume accepting connections
+ BacklogHandler down() and up() methods now working properly
+ Added maxAttempts to TCPNetSyslogConfig[IF] to remove hard-coded
"try twice" loop for trying twice to write a message to a TCP-based
Syslog server
+ Renamed all naming of "backlog" to "backLog" and "Backlog" to
"BackLog" for consistency's sake; except for the literal
TCP Socket concept of "backlog"
+ Fixed MultipleSyslog.getProtocol() to actually return protocol name
+ JUnit test improvements; 75.0% instruction code coverage (EclEmma)
--------------------------------------------------------------------------
Version 0.9.23 (01/23/2009)
+ Added Log4jSyslogBacklogHandler to use Log4j as a backup if a
Syslog protocol fails
+ Improvements to BacklogHandlers to flag "up" and "down" conditions.
+ TCPNetSyslog fixed getWriter(..) to not create new threads upon
a flush() or shutdown() call
--------------------------------------------------------------------------
Version 0.9.22 (12/09/2008)
+ Refactored SyslogConfigIF and AbstractSyslogConfig to use more
interfaces (AbstractSyslogConfigIF, AbstractNetSyslogConfigIF,
TCPNetSyslogConfigIF) in order to reduce forced casts and forced
inheritance models
+ JUnit test improvements; 74.1% instruction code coverage (EclEmma)
--------------------------------------------------------------------------
Version 0.9.21 (11/26/2008)
+ Modified PooledTCPNetSyslogConfig to force maxIdle, minIdle, and
maxActive to the same value when isThreaded is true
+ TCPNetSyslog overridden for backlog(..) methods to strip delimiter
from message
+ Fixed SyslogServer.exists(String protocol) to be case insensitive
+ JUnit test improvements; now at 72.2% code coverage (EclEmma)
--------------------------------------------------------------------------

defaults to 2

with NetSyslogPoolFactory, PooledTCPNetSyslog, PooledTCPNetSyslogConfig,
and PooledSSLTCPNetSyslogConfig
+ Reworked the "Writer" implementation into AbstractNetWriter to support
pooling
+ Added Threaded JUnit tests for TCP, UDP, and pooling
+ Added MultipleSyslog and MultipleSyslogConfig to conveniently send
to more than one Syslog server simultaneously
+ JUnit test improvements; now at 71.3% code coverage (EclEmma)
--------------------------------------------------------------------------
Version 0.9.17
+ Added support for secure syslog messages (via TCP over SSL) with
SSLTCPNetSyslogWriter and SSLTCPNetSyslogConfig classes

syslog implementations in lieu of only the UnixSyslog syslog
implementation
