Toil Enforces Explicit SQLite Transactions Across Python Runtimes

Fri, 18 Sep 2026 03:43:50 +0000

Toil is a Python based workflow engine designed to execute complex compute pipelines across cloud infrastructure and High Performance Computing environments. Recent activity in the repository addresses database transaction isolation within the history tracking subsystem to ensure reliable state persistence across Python runtimes. The updates resolve transaction rollback edge cases when running pipelines on Python versions older than Python 3.12.

Toil Adds --doubleTime For Slurm Walltime Retries

Thu, 03 Sep 2026 17:08:00 +0000

Toil is a Python workflow engine that runs CWL, WDL, and native Python pipelines on laptops, clouds, and HPC clusters. On 1 September 2026 the DataBiosphere/toil tree gained --doubleTime, an opt in flag that retries a timed out job with twice the walltime. The same change teaches Slurm to report a timeout as TIMELIMIT instead of a generic kill, which is the signal the retry path actually needs.
