real-logic/aeron 1.29.0

on GitHub

• Further refinement and additions to the C client which is currently at experimental status.
• Improve error messages when parsing URI params.
• Fix application of sparse terms in Java Media driver when not used on a per channel basis.
• Add support for session based subscriptions on IPC and spies to the C media driver.
• Use ssc (Spies Simulate Connection) only in cluster when membership size is 1. This avoids the leader racing ahead of followers which are catching up and a number of cases where the start of a recording can be missed.
• Add the ability to have spies simulation connection (ssc) configured on a per stream basis for both Java and C media drivers.
• Fix some false sharing issued introduced for channel re-resolution checking to give a tighter latency distribution.
• Add state checks to Cluster operations so services do no use features at inappropriate times.
• Rework build script to help IDEA recognise generated classes and not give false compilation errors.
• Significantly improve throughput of C media driver when used with the Solarflare ef_vi premium extension to provide the best latency and throughput possible.
• Fix short send counting in C media driver.
• Change Archive session workers to behave more like normal Agents so that stack traces are more informative when debugging.
• Improve error handling and cluster elections when dynamic membership is being used and increase test coverage.
• Improve session checks when re-adding a publication with the same session id.
• Refinements to Cluster Backup.
• Change defaults for throughput tests to use 8k rather than 16k MTUs to better fit with jumbograms.
• Close recording Archive recording subscriptions with autoStop = true that have an error on first image.
• Detect Archive errors in Cluster so waiting operations can abort and be retried.
• Fix aeron_ftruncate on Windows for native driver so it behaves more like Linux. This addresses races with client and driver starting at the same time which can result in a corrupt CnC file.
• Avoid int overflow with Cluster snapshots greater than 2GB in length. PR #959.
• Fix C++ client compile for CentOS 7 with GCC 4.8.5.
• Add flow control (fc) and group tag (gtag) URI params to Archive stripped channels.
• Configurable buffer length for Archive record and replay file operations to control batch size via aeron.archive.file.io.max.length. New default shows a marked increase in throughput and reduced latency in all our tests.
• Capture logs from failed Cluster tests to aid debugging.
• Agent logging for untethered subscription state changes in Java and C media driver.
• Expanded agent logging for archive activities to aid debugging.
• Fix segfault in C media driver if transport cannot bind.
• Add Java 14 to CI.
• Add native sanitize builds to CI.
• Upgrade to Versions 0.29.0.
• Upgrade to Checkstyle 8.34.
• Upgrade to Mockito 3.4.4.
• Upgrade to BND 5.1.1.
• Upgrade to ByteBuddy 1.10.13.
• Upgrade to HdrHistogram 0.11.0 for C.
• Upgrade to Gradle 6.5.1.
• Upgrade to SBE 1.19.0.
• Upgrade to Agrona 1.6.0.
