This is a vote to release Log4j 2.15.0, the next version of the Log4j 2 project.
Please download, test, and cast your votes on the log4j developers list.
[] +1, release the artifacts
[] -1, don't release because...
The vote will remain open for 72 hours (or more if required). All votes are
welcome and we encourage everyone to test the release, but only Logging PMC
votes are “officially” counted. As always, at least 3 +1 votes and more
positive than negative votes are required.
Changes in this release include:
New Features
• LOG4J2-3198: Pattern layout no longer enables lookups within message
text by default for cleaner API boundaries and reduced formatting overhead. The
old 'log4j2.formatMsgNoLookups' which enabled this behavior has been removed as
well as the 'nolookups' message pattern converter option. The old behavior can
be enabled on a per-pattern basis using '%m{lookups}'.
• LOG4J2-3194: Allow fractional attributes for size attribute of
SizeBsaedTriggeringPolicy. Thanks to markuss.
• LOG4J2-2978: Add support for Jakarta EE 9 (Tomcat 10 / Jetty 11)
Thanks to Michael Seele.
• LOG4J2-3189: Improve NameAbbreviator worst-case performance.
• LOG4J2-3170: Make CRLF/HTML encoding run in O(n) worst-case time,
rather than O(n^2). Thanks to Gareth Smith.
• LOG4J2-3133: Add missing slf4j-api singleton accessors to
log4j-slf4j-impl (1.7) StaticMarkerBinder and StaticMDCBinder. This doesn't
impact behavior or correctness, but avoids throwing and catching
NoSuchMethodErrors when slf4j is initialized and avoids linkage linting
warnings.
• LOG4J2-2885: Add support for US-style date patterns and micro/nano
seconds to FixedDateTime. Thanks to Markus Spann.
• LOG4J2-3116: Add JsonTemplateLayout for Google Cloud Platform
structured logging layout.
• LOG4J2-3067: Add CounterResolver to JsonTemplateLayout.
• LOG4J2-3074: Add replacement parameter to ReadOnlyStringMapResolver.
• LOG4J2-3051: Add CaseConverterResolver to JsonTemplateLayout.
• LOG4J2-3064: Add Arbiters and SpringProfile plugin.
• LOG4J2-3056: Refactor MD5 usage for sharing sensitive information.
Thanks to Marcono1234.
• LOG4J2-3004: Add plugin support to JsonTemplateLayout.
• LOG4J2-3050: Allow AdditionalFields to be ignored if their value is
null or a zero-length String.
• LOG4J2-3049: Allow MapMessage and ThreadContext attributes to be
prefixed.
• LOG4J2=3048: Add improved MapMessge support to GelfLayout.
• LOG4J2-3044: Add RepeatPatternConverter.
• LOG4J2-2940: Context selectors are aware of their dependence upon the
callers ClassLoader, allowing basic context selectors to avoid the unnecessary
overhead of walking the stack to determine the caller's ClassLoader.
• LOG4J2-2940: Add BasicAsyncLoggerContextSelector equivalent to
AsyncLoggerContextSelector for applications with a single LoggerContext. This
selector avoids classloader lookup overhead incurred by the existing
AsyncLoggerContextSelector.
• LOG4J2-3041: Allow a PatternSelector to be specified on GelfLayout.
• LOG4J2-3141: Avoid ThreadLocal overhead in RandomAccessFileAppender,
RollingRandomAccessFileManager, and MemoryMappedFileManager due to the unused
setEndOfBatch and isEndOfBatch methods. The methods on LogEvent are preferred.
• LOG4J2-3144: Prefer string.getBytes(Charset) over
string.getBytes(String) based on performance improvements in modern Java
releases.
• LOG4J2-3171: Improve PatternLayout performance by reducing
unnecessary indirection and branching.
Fixed Bugs
• LOG4J2-3201: Limit the protocols JNDI can use by default. Limit the
servers and classes that can be accessed via LDAP.
• LOG4J2-3114: Enable immediate flush on RollingFileAppender when
buffered i/o is not enabled. Thanks to Barnabas Bodnar.
• LOG4J2-3168: Fix bug when file names contain regex characters. Thanks
to Benjamin Wöster.
• LOG4J2-3110: Fix the number of {}-placeholders in the string literal
argument does not match the number of other arguments to the logging call.
Thanks to Arturo Bernal.
• LOG4J2-3060: Fix thread-safety issues in DefaultErrorHandler. Thanks
to Nikita Mikhailov.
• LOG4J2-3185: Fix thread-safety issues in DefaultErrorHandler. Thanks
to mzbonnt.
• LOG4J2-3183: Avoid using MutableInstant of the event as a cache key
in JsonTemplateLayout.
• LOG4J2-2829: SocketAppender should propagate failures when
reconnection fails.
• LOG4J2-3172: Buffer immutable log events in the SmtpManager. Thanks
to Barry Fleming.
• LOG4J2-3175: Avoid KafkaManager override when topics differ. Thanks
to wuqian0808.
• LOG4J2-3160: Fix documentation on how to toggle log4j2.debug system
property. Thanks to Lars Bohl.
• LOG4J2-3159: Fixed an unlikely race condition in
Log4jMarker.getParents() volatile access.
• LOG4J2-3153: DatePatternConverter performance is not impacted by
microsecond-precision clocks when such precision isn't required.
• LOG4J2-2808: LoggerContext skips resolving localhost when hostName is
configured. Thanks to Asapha Halifa.
• LOG4J2-3150: RandomAccessFile appender uses the correct default
buffer size of 256 kB rather than the default appender buffer size of 8 kB.
• LOG4J2-3142: log4j-1.2-api implements LogEventAdapter.getTimestamp()
based on the original event timestamp instead of returning zero. Thanks to John
Meikle.
• LOG4J2-3083: log4j-slf4j-impl and log4j-slf4j18-impl correctly detect
the calling class using both LoggerFactory.getLogger methods as well as
LoggerFactory.getILoggerFactory().getLogger.
• LOG4J2-2816: Handle Disruptor event translation exceptions. Thanks to
Jacob Shields.
• LOG4J2-3121: log4j2 config modified at run-time may trigger
incomplete MBean re-initialization due to InstanceAlreadyExistsException.
Thanks to Markus Spann.
• LOG4J2-3107: SmtpManager.createManagerName ignores port. Thanks to
Markus Spann.
• LOG4J2-3080: Use SimpleMessage in Log4j 1 Category whenever possible.
• LOG4J2-3102: Fix a regression in 2.14.1 which allowed the
AsyncAppender background thread to keep the JVM alive because the daemon flag
was not set.
• LOG4J2-3103: Fix race condition which can result in
ConcurrentModificationException on context.stop. Thanks to Mike Glazer.
• LOG4J2-3092: Fix JsonWriter memory leaks due to retained excessive
buffer growth. Thanks to xmh51.
• LOG4J2-3089: Fix sporadic JsonTemplateLayoutNullEventDelimiterTest
failures on Windows. Thanks to Tim Perry.
• LOG4J2-3075: Fix formatting of nanoseconds in JsonTemplateLayout.
• LOG4J2-3087: Fix race in JsonTemplateLayout where a timestamp could
end up unquoted. Thanks to Anton Klarén.
• LOG4J2-3070: Ensure EncodingPatternConverter#handlesThrowable is
implemented. Thanks to Romain Manni-Bucau.
• LOG4J2-3054: BasicContextSelector hasContext and shutdown take the
default context into account
• LOG4J2-2940: Slf4j implementations walk the stack at most once rather
than twice to determine the caller's class loader.
• LOG4J2-2965: Fixed a deadlock between the AsyncLoggerContextSelector
and java.util.logging.LogManager by updating Disruptor to 3.4.4.
• LOG4J2-3095: Category.setLevel should accept null value. Thanks to
Kenny MacLeod, Gary Gregory.
• LOG4J2-3174: Wrong subject on mail when it depends on the LogEvent
Thanks to romainmoreau.
