Revision history for Log::Log4perl
##################################################
0.34 06/08/2003
* (ms) James FitzGibbon <james.fitzgibbon@target.com> noticed a major
bug in Log::Log4perl::Appender::File and provided a patch. Problem
was that 0.33 was reusing the same file handle for every opened file,
causing all messages to end up in the same file.
0.33 05/30/2003
* (kg) CPAN rt#2636, coordinating XML::DOM version required across modules
and unit tests
* (ms) Removed Log::Dispatch dependency, added standard
Log::Log4perl::Appender appenders File and Screen.
Log::Dispatch is still supported for backwards compatibility
and special purpose appenders implemented within this hierarchy.
0.32 05/17/2003
* (ms) Added fix to Makefile.PL to compensate for MakeMaker bug
in perl < 5.8.0, causing man pages below Log::Log4perl::Config
not to be installed. Thanks to Mathieu Arnold <mat@mat.cc>
for bringing this up.
* (ms) 0.31 had a Win32 test suite glitch, replaced getpwuid()
(not implemented) by stat() for Safe test.
0.31 05/08/2003
* (kg) fixed bug Appender::DBI where it was consuming the message
array before other appenders could get to it
* (ms) changed config_and_watch to ignore clock differences between
system time and file system time (helpful with skewed NFS
systems). Added Log::Log4perl::Config::Watch.
* James FitzGibbon <james.fitzgibbon@target.com>: Added support for
optionally restricting eval'd code to Safe compartments.
* (ms) allow/deny code in configuration files should now be controlled
via the accessor Log::Log4perl::Config->allow_code(0/1).
$Log::Log4perl::ALLOW_CODE_IN_CONFIG_FILE is still supported
for backwards compatibility.
0.30 03/14/2003
* (ms) Added Log4perl custom filter logic and standard filter set
* (kg) Added url support to init(), finally documenting it
* (kg) Finished implementation of DOMConfigurator allowing xml configs.
* (ms) Corrected DateFormat inconsistencies as reported by
Roger Perttu <roger.perttu@easit.se>
0.29 01/30/2003
* (kg) Removing debugging from 0.28, big woops
* (kg) Fixing 036JSyslog.t, Syslog implementations are too often broken
to base any results on.
* (kg) Fixing XML-DOM tests, Data::Dumper doesn't return data exactly the
same way.
0.28 (01/28/2003)
* (ms) '#' in the conf file are now interpreted as comment starters only
if they're at the start of a line with optional whitespace.
The previous setting (comments starting anywhere) had problems
with code containing '#''s, like in layout.cref = sub { $#_ = 1 }
* (ms) warp_message accepts code refs or function names
* (kg) Split config bits into PropertyConfigurator and implemented
DOMConfigurator for XML configs.
* (kg) Adding appender.warp_message parameter as a help to DBI
appender
* (kg) Added NoopLayout to help DBI appender
* (ms) Added message output filters:
log({filter => \&filter, value => $value})
* (kg) t/024WarnDieCarp was assuming / as directory separator, failed
on Win32
* (kg) implemented JavaMaps for NTEventLogAppender, SyslogAppender
* (kg) found and addressed circular ref problem in Logger->reset
* (kg) moved TestBuffer under Appender/ directory along with DBI
* (kg) fixed docs, Pattern layout, %f not supported, s/b %F
* (kg) added Log::Log4perl::Appender::DBI to implement JDBCAppender
* (ms) Every value in the config file can now be a perl function,
dynamically replaced by its return value at configuration
parse time
* (ms) NDC now prints entire stack, not just
top element (as mandated by Log4j)
* (ms) Allow trailing spaces after a line-breaking '\' in the
config file to be fault-tolerant on cut-and-pasted code
0.27 12/06/2002
* (ms) Updated FAQ with "Recipes of the Week"
* (ms) Added Log::Log4perl::NDC (Nested Diagnostic Contexts) and
Log::Log4perl::MDC (Mapped Diagnostic Contexts)
* (ms) LOGDIE and LOGWARN added to stealth loggers
* (ms) Logging methods ($lo->debug(), $lo->info() ...) now return
a value, indicating the number of appenders that the message
was propagated to. If the message was suppressed due to level
constraints, undef is returned. Updated manpage (new section
"return values").
* (ms) Fixed bug reported by Francisco Olarte Sanz.
<folarte@peoplecall.com>: ISO date format and documentation mixed
up MM with mm in the simple date format
* (kg) User-defined conversion specifiers for PatternLayout in
configuration file and as C API
* (kg) implementing map to log4j.RollingFileAppender
* (kg) trying out oneMessagePerAppender parameter
* (kg) changed unit tests to use File::Spec
0.26 11/11/2002
* (kg) enabled %l (was missing from PatternLayout::define)
* (kg) got rid of "Use of uninitialized value in join or string" message
when some of $logger->debug(@array) when some of @array are undef
* (ms) Stealth loggers and documentation
* (kg) Better error message for case reported by Hai Wu
* (ms) Added Log/Log4perl/FAQ.pm, which the homepage links to
* (ms) Took dependency on Test::More and Test::Simple out of the PPD file
because of a problem with Activestate 5.6.1 reported
by James Hahn <jrh3@att.com>
* (ms) Added Log::Dispatch equivalent levels to the Log4perl loggers,
which are passed on the Log::Dispatch appenders now according
to the priority of the message instead of the default "DEBUG"
setting
* (ms) Added %P process ID to PatternLayout as suggested by
Paul Harrington <Paul-Harrington@deshaw.com>. Also added
%H as hostname
* (kg) Added %min.max formatter to PatternLayout
* (ms) Updated docs for Log::Log4perl::DateFormat
0.25 10/06/2002
* (ms) backwards-compatibility with perl 5.00503
* (ms) added system-wide threshold, fixed java-app thresholds
* (kg) Nested configuration structures for appenders like L::D::Jabber
* (ms) ::Log4perl::Appender::threshold() accepts strings or integer
levels (as submitted by Aaron Straup Cope <asc@vineyard.net>)
* (ms) Fixed logdie/logwarn caller(x) offset bug reported by
Brian Duffy <Brian.Duffy@DFA.STATE.NY.US>
* (ms) dies now on PatternLayout without ConversionPattern (helps detecting
typos in conf files)

* (kg) Fix for init_and_watch and test cases
* (ms) Added documentation for Log::Log4perl::Config
* (ms) Added log4perl.additivity.loggerName conf file syntax
* (ms) Assume Log::Log4perl::Layout prefix of 'relative'
layout class names in conf file (say 'SimpleLayout'
instead of 'Log::Log4perl::Layout::SimpleLayout').
* (ms) accidently appending a ';' at the end of an appender
class in a conf file now spits out a reasonable error message
* (ms) added a by_name() method to TestBuffer to retrieve an
instance of the TestBuffer population by name instead of
relying on the order of creation via POPULATION[x]
(for testing only).
* (kg) Win32 compatibility fixes
0.23 09/14/2002
* Both Log4perl/log4perl is now accepted in conf file
* Added documentation to Log::Log4perl::Appender
* Made Time::HiRes optional. If it's missing, PatternLayout will
just use full seconds as %r.
* SimpleDateFormat "%d{HH:SS}", including predefined formats (DATE etc.)
* Added another cut-and-paste example to the docs (EXAMPLE)
* Added new logdie/logwarn/error_warn/error_die/logcarp/
logcluck/logcroak/logconfess functions written by
Erik Selberg <erik@selberg.com>
* Added PatternLayout documentation
* Changed suppression of duplicate newline in log message algorithm
* Custom levels and inc_level/dec_level/more_logging/less_logging
added by Erik Selberg <erik@selberg.com>
* Append to logfile by default if Log::Dispatch::File is used
(previously clobbered by default)
* Kevin's init_and_watch fix
0.22 8/17/2002
* Threshold settings of appenders:
$appender->threshold($ERROR);
log4j.appender.A.Threshold = ERROR
* Chris R. Donnelly <cdonnelly@digitalmotorworks.com>
submitted two patches:
- extended init() to take obj references (added, also added a test
case and documentation)
- fixed %F and %L if Log4perl is used by a wrapper class (accepted,
but changed variable name to Log::Log4perl::caller_depth as
a tribute to Log::Dispatch::Config, added test case 022Wrap
and documentation
0.21 8/08/2002
* Synopsis shows code samples in Log4perl.pm/README
* Slight Log4j incompatibility but useful: %F{n} lets you
limit the number of entries the source file path is logged
* Erik W. Selberg (erik@selberg.com) suggested having PatternLayout.pm
suppress another \n if the messages already contains a \n and the
format requires a %n. Done.
* Erik W. Selberg (erik@selberg.com) suggested loggers should take
any number of messages and concatenate them. Done.
* Fixed double-init problem and added a test case. Now the entire
configuration is cleared before the second init(). However, this
surfaced a problem with init_and_watch: If a program obtains
references to one or more loggers, rewriting the configuration
file during program execution and re-initing makes these reference
point to loggers which hold obsolete configurations. Fixed that by
code in debug(), info(), etc. which *replaces* (shudder) the
logger reference the program hands in to them with a new one of
the same category. This happens every time if 'init_and_watch' has
been enabled. However, this introduces a small runtime penalty.
This is different from the original log4j, which does some
half-assed re-initialization, because Java isn't expressive enough
to allow for it. Making this thread-safe might be tough, though.
* Added DEBUG statements to Logger.pm and Config.pm to trace execution
(debugging won't work because of "eval"s). Both files define a
constant named DEBUG towards the top of the file, which will
have perl optimize away the debug statements in case it's set to 0.
* A warning is issued now (once) if init() hasn't been called or
no appenders have been defined.
* Added ':levels' target to Log::Log4perl to import $DEBUG, $ERROR,
etc. levels (just like 'use Log::Log4perl::Level' works).
* Added ':easy' target to allow for simple setup
* Code references can be passed in as log messages to avoid parameter
passing penalty
0.20 7/23/2002
* Strip trailing spaces in config file
* Accept line continuations in properties file
* Refactored Logger.pm for speed, defined the logging behavior when
the logger is created, not when a message is logged
* Fixing test suites so that SimpleFormat newline is accounted for
* Fixed a bug with root inheritance where the category name wasn't
coming through
* added init_and_watch
0.19 07/16/2002
* Added Log::Log4perl::Appender::TestBuffer back in the distribution, otherwise
regression test suite would fail.
0.18 07/16/2002
* Failed attempt to fix the Log::Dispatch::Buffer problem.
0.17 07/11/2002
* Updated documentation according to Dave Rolsky's suggestions
* Lots of other documentation fixes
* Fixed bug in renderer, %M was displayed as the logger function
bumped up the level by 1
* Fixed %% bug
0.16 07/10/2002
* Updated documentation for CPAN release
* Applied Kevin's patch to limit it to one Log::Dispatcher
0.15 07/10/2002
* There were name conflicts in Log::Dispatch, because we used *one*
Log::Dispatch object for the *all* loggers in the Log::Log4perl
universe (it still worked because we were using log_to() for
Log::Dispatch to send messages to specific appenders only). Now
every logger has its own Log::Dispatch object. Logger.pm doesn't
call Kevin's anti-dupe logic anymore -- is this ok? Maybe there's
some leftovers which need to be cleaned up.
* Kevin fixed t/014ConfErrs.t after last night's Appender.pm change
0.14 07/09/2002
* (!) Added new class Log::Log4perl::Appender as a wrapper around
Log::Dispatch::*. Layouts are no longer attached to the loggers,
but to the appenders instead. $app->layout($layout) sets the
layout. $logger->add_appender($app) is the new syntax to add
an appender to a logger. The $logger->layout method is gone
for that reason.
* Added documentation on categories
* Added documentation on Log::Log4perl::Appender,
Log::Log4perl::Layout::SimpleLayout,
Log::Log4perl::Layout::PatternLayout.
0.13 07/09/2002
* in the config files, 'debug' is not a level, 'DEBUG' is
* expanded the layouts so that we can add subclassess, added
SimpleLayout, note that api usage changes
-$logger->layout('buf',"The message is here: %m");
+$logger->layout(new
Log::Log4perl::Layout::PatternLayout('buf',"The message is
here: %m"));
* did benchmarks, see doc/benchmark*, t/013Bench.t
* further tweaked errors for bad configuration, added a test for those
0.12 07/08/2002
* Log::Log4perl::Logger->get_logger now accessible via
Log::Log4perl->get_logger()
* Log::Log4perl::Config->init now accessible via
Log::Log4perl->init()
* Adapted test cases to new shortcuts
* Constrained some files to 80 chars width
* Added test case t/009Deuce.t for two appenders in one category
via the config file
* Changed default layout in case there's none defined (SimpleLayout)
* Implemented dictatory date format for %d: yyyy/MM/dd hh:mm:ss
0.11 07/07/2002
* added documentation to Log/Log4perl.pm
* added is_debug/is_error/is_info etc. functions to Logger.pm,
test cases to t/002Logger.t
0.10 07/05/2002
* %p should return level name of the calling function, so
$logger->warn('bad thing!!') should print 'WARN - bad thing'
even if the category is set to debug, so took level_str out of
Logger.pm (kg)
0.09 07/03/2002
* %p should return level name, not number, adding level_str to Logger.pm (kg)
* Level.pm - discriminating: priorities are 1-4, levels are
'info','debug',etc (kg)
0.08 07/03/2002
* Non-root loggers are working now off the config file
0.07 07/02/2002
* Updated documentation
* removed "diagnostics"
0.06 07/01/2002
* Bug discovered by Kevin Goess <cpan@goess.org>, revealed
in 004-Config.t: Wrong layout used if Appender is inherited.
Fixed.
* Changed Log::Log4perl::Appender::TestBuffer to keep track of the
object population -- so we can easily reference them
in the Log::Log4perl test cases. Got rid of get_buffer().
* Added a reset() method to Log::Log4perl and Log::Log4perl::Logger
for easier testing. It resets all persistent loggers to
the inital state.
* Added documentation
0.05 06/30/2002
* Fixed bug with mapped priorities between java/Log::Dispatch
* Java/Perl integration with conf file
0.04 06/30/2002
* Layout tests
* %r to layout
* Added lib4j configuration file stuff and tests
0.03 06/30/2002
* Layout
* Curly braces in Layout first ops
0.02 06/30/2002
* Created Logger and test cases
0.01 06/22/2002
* Where it all began
TODO (not assigned to anybody yet):
##################################################
* objects passed via the config hash are stringified by Config.pm
(requires a significant change on how to init via a hash ref,
something like a HashConfigurator class)
* BasicConfigurator() vs. :easy, PropertyConfigurator()
* get_logger() thread safety (two try to create it at the same time)
* Thread safety with appenders, e.g. two threads calling the
File::Dispatch appender's log method
* Thread safety with re-reading the conf file (watch)
* Object rendering
* log4j.logger.blah = INHERITED, app
* variable subst: a=b log4j.blah = ${a}
* log4j.renderer.blah = blah
* permission problems, init() creates the files, maybe read later by
different uid, no way to set umask?
* Custom filters
TODO Kevin:
##################################################
* use squirrel http://www.perlmeister.com/scripts/squirrel?
* document oneMessagePerAppender as a bona-fide feature
* appender-by-name stuff?
* implement? #"log4j will render the content of the log message according to
# user specified criteria. For example, if you frequently need
# to log Oranges, an object type used in your current project,
# then you can register an OrangeRenderer that will be invoked
# whenever an orange needs to be logged. "
TODO Mike:
##################################################
* index.html on sourceforge should be part of CVS
* Release script should maintain old CPAN message on index.html
* Turning on DEBUG in Logger.pm results in broken test cases and
warnings
* Layout.pm: '%t'
* README tests (Pod::Tests or something)
* Just had a wild idea: Could we possibly utilize the compiler
frontend to eliminate log statements that are not going to be
triggered? This would be a HUGE performance increase!
* Write a bunch of useful appenders for Log::Dispatch like
RollingLogFile
