Sep 1, 2025Concise monthly summary for 2025-09 focused on business value and technical delivery. Key features delivered: - Ported core and engine to call-by-name (CBN) across multiple subsystems, including streaming_workunit_handler, environments, backend wiring, and related migrations to enable CBN-driven execution. This included porting remaining JVM-related files, backends, and tests, plus support for mutually recursive CBN rules and enhanced test utilities. - Release readiness and versioning: prepared 2.29.0.dev4 and dev5 development releases with appropriate changes and versioning. - CI/CD automation and reliability: added a GitHub Action to automate periodic RunsOn AMI creation and fixed the RunsOn AMI building action to improve stability. - FaaS and artifact management: generated a metadata file for FaaS artifacts and separated Python lockfile metadata to improve clarity, caching behavior, and deployment. - Testing and documentation improvements: upgraded tests to use call-by-name friendly patterns, refactored the test suite for CBM, switched tests from mock GETs to mock calls for reliability, and updated documentation/tutorials to reflect call-by-name usage; introduced CBM-specific test markers. - Developer experience and tooling: updated Pex to 2.59.1 and introduced deprecation of Get() in the CBN integration to steer users toward safer patterns. Major bugs fixed: - Fixed RunsOn AMI GitHub Action issues to ensure reliable AMI builds. - Fixed attestation glob patterns to avoid false negatives in verification. - Fixed an inappropriate argument in concurrently() to ensure correct parallel execution semantics. Overall impact and accomplishments: - The work progresses the call-by-name migration, delivering safer execution semantics, better test coverage, and more reliable automated maintenance tasks. This positions Pants for improved stability, performance, and developer productivity, with clearer artifact management and stronger release tooling. Technologies/skills demonstrated: - Python refactoring and large-scale architecture migration to a new evaluation strategy (call-by-name) - Backend and JVM-related porting, environment wiring, and mutual recursion support - Test modernization (CBN-oriented tests, mock call migration) - CI/CD automation (GitHub Actions) and release engineering - Artifact management (metadata generation, separate lockfiles) and docs/tutorial modernization
