PROFILE
Jeremy Thorp
Jeremy Thorp contributed to the wiredtiger/wiredtiger repository by modernizing coding standards, improving CI/CD reliability, and enhancing cross-platform build automation. He addressed macOS build issues, streamlined the CI build matrix, and fixed test flakiness by refining test assertions and automating artifact handling. Using C, C++, and shell scripting, Jeremy implemented robust debugging and testing practices, enforced compiler flag policies, and improved JSON handling in command-line tools. His work stabilized documentation, reduced technical debt, and strengthened security by removing legacy code. These efforts resulted in more maintainable code, faster feedback cycles, and reliable development workflows across multiple operating systems and architectures.

May 1, 2025May 2025 (2025-05) monthly summary for wiredtiger/wiredtiger: Focused on reliability and correctness in stress testing. Implemented a targeted fix for the bounded_cursor_stress test to correctly handle scenarios where a normal cursor returns WT_NOTFOUND while a bounded cursor returns WT_ROLLBACK due to concurrent data modifications. This change strengthens test accuracy under high-concurrency conditions and reduces flaky outcomes in CI. Commit details are included below to illustrate the change scope.

Jan 1, 2025Month: 2025-01 Concise monthly summary focusing on key accomplishments, with emphasis on business value and technical achievements for wiredtiger/wiredtiger. Key features delivered: - Restored MacOS build capability and Evergreen CI stability for WiredTiger in the macOS ecosystem. This included addressing cross-platform build issues, adjusting test case compilation, and updating the CI workflow to fetch artifacts and use standard compile/fops tasks. In addition, artifact uploads for Mac builds were temporarily disabled to restore basic functionality while stabilizing the pipeline. Major bugs fixed: - Fixed cross-platform build issues and CI failures on macOS in Evergreen, enabling macOS builds and tests to run reliably again. - Resolved issues around artifact handling and test workflow on Mac builds, reducing flaky test runs and build time regressions. Top 3-5 achievements: - WT-13970 Get WiredTiger building on Macs again (#11381) - WT-13977 Re-enable Mac compiles on Evergreen (#11389) - WT-13951 - Fully re-enable Mac testing on the Evergreen waterfall (#11459) Overall impact and accomplishments: - Reinstated reliable macOS build and test coverage for WiredTiger, restoring end-to-end CI functionality on macOS and reducing pipeline flakiness. This enables ongoing development, faster feedback loops, and safer releases for macOS users and developers.
