July 2026 PelicanPlatform/pelican monthly summary focused on reliability improvements, API consistency, and build stability. Implemented robust post-transfer error reporting and failover handling, expanded test coverage for multi-attempt transfers, standardized Swagger API definitions, and upgraded build dependencies to improve stability and developer velocity.

June 2026 performance — PelicanPlatform/pelican: Completed migration to V2 advertisement format across Pelican and director, removing legacy V1 support and conversions. Introduced a deprecated 299-returning endpoint to ease transition and removed V1 fallback logic. Cleaned up architecture by eliminating V1-related code paths and endpoints (including V1 GET /api/v1.0/director/listNamespaces). Updated tests to reflect V2-only flow and adjusted related cache/scitokens tests. Implemented a dependency upgrade of Docker image xrdcl-pelican to 1.7.1 for security fixes and compatibility.

In May 2026, delivered two focused changes in Pelican: (1) Director Input Decision Logic Stabilization to eliminate non-determinism and improve test reliability; (2) Pelican URL Error Messaging Enhancement to guide users when entering incorrect URL formats (e.g., three slashes). These changes reduce support load, improve user satisfaction, and strengthen code quality with traceable commits.

April 2026 PelicanPlatform/pelican monthly performance summary focusing on business value and technical achievements. The month centered on delivering features that improve observability, configuration flexibility, and decision gating, complemented by targeted tests to ensure reliability and maintainability.

Month: 2026-03. PelicanPlatform/pelican delivered key reliability and usability improvements that reduce operational overhead and improve client-server robustness. 1) Director Tests Enablement gates test execution behind explicit server enablement, reducing unnecessary test runs and clarifying messaging when tests are disabled. 2) Proxy Handling Enhancements strengthen proxy detection by respecting standard environment variables and a client configuration override, with expanded test coverage to prevent deployment-time proxy issues. 3) Client Authorization Error Handling Improvements provide precise reporting when a token is not sent and mark certain authorization errors as retryable when public namespaces rely on potentially stale caches, improving resilience and error recovery.

February 2026 monthly summary for PelicanPlatform/pelican: Delivered robust error handling, validation improvements, and XRootD integration stability. Implemented new Pelican error codes, wrapped errors with PelicanErrors, and expanded tests to improve reliability and developer experience. Strengthened storage operations through version checks and build/test hygiene, resulting in clearer error semantics and reduced MTTR. Demonstrated cross-platform readiness with Windows cleanup and defaults consolidation.

January 2026 monthly summary for PelicanPlatform/pelican focused on reliability, security, and cross-platform robustness. Implemented critical features, fixed key reliability bugs, and improved testing and code quality to deliver solid business value.

December 2025 monthly summary for PelicanPlatform/pelican focused on delivering safer, more robust data transfer workflows and improving error handling with stronger alignment to system permissions. The month included key feature delivery for temp-file-based downloads with an inplace transfer option, plus significant hardening of HTTP error messaging, permission handling, and upload behavior under restricted responses.

November 2025 focused on hardening error handling, improving resilience and observability in PelicanPlatform/pelican, and standardizing error taxonomy across download/upload and federation workflows. Delivered robust error wrappers for connection setup, proxy failures, memory allocation issues, TLS alerts, and directory listing capabilities; standardized exit codes and retry behavior to enable safer automated retries and clearer incident categorization. Expanded test coverage and refactoring to improve maintainability and reduce regression risk across error paths, download/upload wrappers, and federation discovery.

August 2025 — PelicanPlatform/pelican: Delivered a critical bug fix that enhances robustness of object_get by validating the destination directory existence before operations, and updated repository structure and CI workflow to improve maintainability and testing. The fix prevents segmentation faults when the destination directory is missing and ensures safe operation with pack=auto across edge cases. Revisions to repository scaffolding and testing infrastructure strengthen production reliability and set a solid foundation for future feature work.

May 2025 — osg-htchub.io.git: Delivered foundational YAML data governance enhancements, expanded publicObject support for population of public projects, integrated IceCube and GlueX YAMLs, refreshed NCAR YAML/assets, and strengthened core YAML quality. These efforts improved data visibility, consistency, and QA readiness, enabling faster onboarding of new datasets and more reliable data provisioning for public projects.

February 2025 monthly summary for PelicanPlatform/pelican: Delivered a critical namespace registration bug fix to ensure accurate server identification across cache and origin servers. Reverted a prior change that used Server.Hostname as the namespace prefix and implemented correct identifiers: Xrootd.Sitename for cache servers and Server.ExternalWebUrl for origin servers. The fix stabilizes namespace routing, reduces cross-type misidentification, and improves reliability during deployments and scaling of cache/origin roles. This change, captured in commit 8a7fe2f328db58b2ee3d0523753dddb1d2fa69a0, enhances service discovery and downstream analytics. Business value: lower risk of misrouting, fewer manual interventions, and smoother upgrades.

Month: 2024-11 — PelicanPlatform/pelican: Key observability enhancements around director redirections. Reintroduced Prometheus metrics for director redirections (cache/origin) and GeoIP error logging. Restored network label visibility by masking client IPs and applying the network label to redirection and GeoIP error metrics to improve observability and troubleshooting of director behavior and location data. Addressed gaps from earlier metric removals via targeted reverts, stabilizing metrics collection and dashboards. This work provides faster issue diagnosis, better data-driven routing decisions, and privacy-conscious analytics for the Pelican platform.
