Apr 1, 2026April 2026 monthly review for the HPCC Platform repository focused on extending command-line tooling and offline validation capabilities. Delivered a new offline validation command (checkdelta) to verify Dali SDS delta files by cross-checking embedded CRC and SIZE headers with computed values, enabling offline data integrity checks without a running Dali server. No major bugs fixed this month based on available data; the team concentrated on feature delivery and quality checks.

Mar 1, 2026March 2026 — HPCC-Platform delivered notable stability, configurability, and cross-plane capabilities. Delivered a deadlock fix when copying superfiles from a foreign Dali; introduced environment-based deployment name override for Kubernetes; added remote storage access across bare metal and alternative planes; completed release-version bumps across platform components for clear upgrade paths; and hardened save operations to prevent concurrent saves from corrupting ignoreExternals state. Result: reduced operational risk, streamlined deployments, and better cross-environment data access.

Feb 1, 2026February 2026 performance summary for hpcc-systems/HPCC-Platform. Delivered business value through release hygiene, API enhancement, reliability improvements, and security controls across the platform. Consolidated release versioning across platform, application, and Helm charts for multiple version lines and updated repository hygiene (gitignore for CMakeUserPresets.json). Launched a new File Listing API with enhanced filtering and field projection, backed by regression tests; deprecated the older LogicalFileList for efficiency. Fixed a critical Dali transaction race condition that could commit transactions out of order, improving stability under load. Refactored large-file handling to use buffered writes, reducing risk of ENOSPC errors and increasing write reliability. Enforced Coalescer access permissions to require Dali access, tightening security and access control across the data path.

Dec 1, 2025December 2025 monthly summary for hpcc-systems/HPCC-Platform: Delivered high-impact features, reliability fixes, and maintenance improvements across the platform with a focus on containerized deployments, configuration-driven behavior, and enhanced postmortem tooling. Key outcomes include Azure Storage Default Credentials Inheritance enabling seamless default credential inheritance for Azure storage API calls; Configurable Job Scheduling Timeout (schedulingTimeoutSecs) propagated to global config templates and passed through to waitJob, improving reliability of containerized job scheduling; and Release Versioning Updates ensuring alignment of application and Helm chart versions (9.10.89, 9.12.65, 9.14.45, 10.0.19). Critical stability fixes addressed postmortem synchronization, splitter resilience, and unscheduled agent job handling, complemented by improvements to KJ handling for out-of-cluster parts, group management synchronization, testing, and memory management optimizations. Maintenance work included cleaning up the repo by migrating tools/workunits out of the tree. These changes were implemented via targeted commits across multiple HPCC-Platform components, examples include: d12b7b7db31874af1e261a56271dd224922ad376 (HPCC-35480), cefb86c860cab50b5da7cc5029b69c4288c458a2, 18c9555e6d48bb2e70b423bf475dcdaac13373dc, d71cc0dea89fc700fa444450097d784fa193abdc, 9dc275f335279047e3b3e20485dfdd397385ee5f, 1ff413f8a9aca03c4bf9786ea0d03383b1eedb1e, cc956ca6c86b58e3df9ce4ee7ef9e68ddbdfb4c7, bbbeb58fb0231d592b0a5e7dd2a25ccc1682a626, afb3eb2dcb0ff1a4ca5170fcf1a9c69aaeb4d17f, 36089a1f23ea20e638f271a3912c0c168fab7bb4, fb36180a6a735f36cc415b3420cab10ad267597b, bffb4bb0571b4957a809dddcf0816d36ec08cb31, 862ffc1902fc678cdd0beba3052bc8f8f77dce18, ddddf0a9614120d4d48b44a0cb3b7f08bd28308d, 454b5882f9c8004768180bfe5fd28ff880592577, a5f8d8d6503024bc8b6cbb6d7babe5460c819f7d
