PROFILE
Sepehr Heydari
Worked on the gitlabhq/gitlab-runner repository, delivering two targeted backend features over two months. Enhanced S3 cache reliability by extending the S3v2 presigned URL logic to support the HEAD method, enabling efficient object existence checks without downloads and improving test coverage using Go and in-memory S3 servers. Subsequently, improved custom executor compatibility by exposing CI-defined service variables to executor scripts, adding a Variables field to the jsonService struct and refining variable parsing logic to handle complex values. Focused on Go-based API development and backend testing, these contributions addressed reliability, maintainability, and performance in CI caching and variable propagation workflows.

May 1, 2026In May 2026, delivered a focused improvement to variable handling for custom executors in gitlab-runner (Month: 2026-05). Implemented exposure of service variables to custom executor scripts by adding a Variables map[string]string field to the jsonService struct and wiring it to populate from Image.Variables when building the environment, ensuring CI-defined variables are not dropped and accessible to executors. Also fixed a parsing issue in test helpers by switching from strings.Split to strings.SplitN(n=2), enabling correct handling of '=' in variable values. These changes reference commit 1cce0ef32f62d68cffc2a05e0b97f3cc7b94a242 and address #39331, delivering improved reliability and compatibility for CI variable propagation.

Apr 1, 2026Month: 2026-04 Overview: Implemented a targeted S3 presigned URL enhancement and accompanying tests in gitlab-runner to improve reliability and performance of cache existence checks. The change extends the S3v2 presign URL flow to support the HEAD method, enabling existence checks without downloading objects, and includes regression tests to guard against future breaks.
