Codekvast Release Notes

1.4.1

6. Agent facing code moved to the new codekvast-intake service.

1.4.0

1. Bug fix: codekvast-javaagent now ignores types annotated with @org.aspectj.lang.annotation.Aspect. This fixes a bug where a Spring-managed @Aspect clashes with the Codekvast-managed AspectJ load-time weaver, so that the aspect does not kick in.
2. Added Java 14 and 15 to the agent test suite.
3. codekvast-javaagent now detects default methods in interfaces.
4. codekvast-javaagent accepts apiKey (aka CODEKVAST_API_KEY or -Dcodekvast.apiKey) as synonym to licenseKey.
5. Dashboard: handler for deadlock exceptions.
6. Lock management: now uses the database functions GET_LOCK() and RELEASE_LOCK() instead of SELECT ... FOR UPDATE
7. Dashboard: now refuses to import synthetic methods. WeederService removes already imported synthetic methods.
8. Upgraded to Gradle 6.5, Spring Boot 2.2.7, Kotlin 1.3.72 plus some more
9. Converted deployment model from EC2 "pets" to ECS Fargate "cattle".
10. Automatic cleanup of disappeared methods on codebase import.

1. codekvast-javaagent does not log on SEVERE level anymore.
2. Bug fix: Unique index on methods.signature is now case-sensitive

1.3.1

1. codekvast-javaagent logs a warning about missing mandatory properties and simply does not start even if codekvast.enabled=true. It does not throw an exception as before.

1.3

1. codekvast-javaagent does not require any mandatory parameters when $CODEKVAST_ENABLED=false or -Dcodekvast.enabled=false
2. Fixed some UX glitches in Dashboard's Method form.
3. Added '*.canEqual(java.lang.Object)' to synthetic methods

1.2

1. Upgraded to Spring Boot 2.2
2. Upgraded to MariaDB 10.4
3. New field "environment" in the GetConfigPoll (java-agent 1.1 is still supported)

1.1

1. Support for uploading class.protectionDomain.codeSource.location for each method
2. The agent supports running on Java 8, 9, 10, 11, 12 and 13. NOTE: The support for Java 7 is dropped!
3. Server is now built with Java 12, but still runs on Java 11.
4. Replace Server Error 500 caused by RequestRejectedException with a simple 404.
5. Bug fix: eliminating methods in search results that haven't been tracked long enough.
6. Removed the possibility to delete terminated agents from the dashboard UI (it is now automatic, based on the retention period).
7. Includes retentionPeriodDays in 'Tracked For' popup.
8. Upgraded to Spring Boot 2.1.9, Kotlin 1.3.50. Also upgraded Lombok, Mockito, jslack and logstash-logback-encoder.

1. Corrected a bug in codekvast-javaagent: now it deletes /tmp/codekvast-nnn/META-INF/aop.xml on JVM termination.
2. Added "hostname" field to agent config.
3. Changed the way the agent's codekvast.conf is located: if one of -Dcodekvast.configuration or CODEKVAST_CONFIG is specified, no automatic locations are examined. This makes it possible to disable the agent without editing or moving the config file.
4. Upgraded to Spring Boot 2.1.3, Angular 7.2.6, TypeScript 3.3.3
5. Added support for Basic proxy authentication in codekvast-javaagent.
