0.6.0

Gollum 0.6.0 contains breaking changes over version 0.5.x.
Please read the release notes carefully

Gollum 0.6.0 dependency management switches from go-dep to go-modules.
As of this is recommended to use go 1.11 or later for development.
Go 1.10 and 1.9 are still supported. Support for Go 1.8 or older has been dropped.

No Linux/ARMv6 binary has been included in this build due to a build error in the sarama library.

New with 0.6.0

• Added a new flag "-mt" to choose the metrics provider (currently only prometheus).
• Consumer.File setting "Files" now supports glob patterns.
• Consumer.Syslog now allows non-standard protocol types (see issue #234)
• Message metadata can now store arbitrary data
• When not setting the numbers of CPU, gollum will try to use cgroup limits
• format.Cast for changing metadata field types
• format.Override to set static field values

Breaking changes with 0.6.0

• Format.SplitPick default delimiter is now ","
• Multiple formatters have been renamed to support the new metadata model
• Metrics are now collected using go-metrics. This allows e.g. prometheus output (default).
  Old-style metrics have been removed and many metrics names have changed.
• Consumer.File setting "File" has been renamed to "Files"
• Consumer.File setting "OffsetFile" changed to "OffsetPath" to support multiple offset files per consumer.
• Consumer.File setting "PollingDelay" has been renamed to "PollingDelayMs".
• Metadata type has changed from map[string][]byte to tgo.MarshalMap.
• Deserializing messages written by v0.5.x will lead to metadata of those message to be discarded.
• Removed support for go 1.8 in order to allow sync.Map
• The functions Message.ResizePayload and .ExtendPayload have been removed in favor if go's slice internal functions.

0.5.4

This is a critical patch release.

It fixes various problems with producer.Spooling that prevented it from working at all.
The issues were most likely introduced during the transition from 0.4.x to 0.5.x.

This version has been built with go 1.12.3

Fixed with 0.5.4

• producer.spooling is now functional again as messages were not written correctly since 0.5.0 (#248).
• producer.spooling now does not block upon shutdown (#248).
• metadata is now handled correctly when messages are sent to fallback (#247).
• producer.socket now sends messages directly to fallback if connect fails.

0.5.3

This is a critical patch release.

It fixes a GC crash caused by the message payload memory handler.
If your plugins use core. MessageDataPool.get(size) please replace it with make([]byte, size).

The buffer causing this was introduced with 0.5.0 but the bug seems to occur only when building with go 1.10.
We decided to remove the buffer as it's allocation speed improvements showed to be only minor anyways.

v0.5.2

This is a patch / minor features release.

All binaries have been compiled with go 1.10.1.

New with 0.5.2

• The version number is now generated via make and git. This will properly identify versions between releases.
• New producer.AwsCloudwatchLogs. Thanks to @luqasz
• The makefile has been cleaned up and go meta-linter support has been added

Fixed with 0.5.2

• consumer.Kafka now properly commits the consumer offsets to kafka. Thanks to @crewton
• producer.awsKinesis failed to produce records under certain conditions
• The consumer.Kafka folderPermissions property is now correctly applied
• formt.ExtractJSON trimValues property is now correctly applied
• The gollum binary inside the Dockerfile is built on the same baseimage as deployed
• Filter will now always filter out the MODIFIED message, not the original. This behavior is more "expected".

v0.5.1

This is a patch / minor features release.

All vendor dependencies have been updated to the latest version and binaries have been compiled with go 1.9.3.

New with 0.5.1

• format.MetadataCopy has been updated to support free copying between metadata and payload
• producer.ElasticSearch alles setting the format of timeBasedIndex
• format.GrokToJSON has new options: RemoveEmptyValues, NamedCapturesOnly and SkipDefaultPatterns
• using dep for dependencies instead of glide

Fixed with 0.5.1

• fixed inversion of -lc always
• fixed a nil pointer panic with producer.elasticsearch when receiving messages with unassigned streams
• producer.ElasticSearch settings are now named according to config
• producer.ElasticSearch dayBasedIndex renamed to timeBasedIndex and it's now working as expected
• updated dependencies to latest version (brings support for kafka 1.0, fixes user agent parsing for format.processTSV)

v0.5.0
