8.1.0b1

Note: this is a beta release with new functionality immediately needed by Cactus.

Highlighted Features Added

• Toil can now publish workflow execution metrics to Dockstore for workflows where it knows the TRS ID (i.e. workflows run by TRS ID or Dockstore URL) (#5159).
  • Toil now saves workflow execution history in ~/.toil/history.sqlite
  • Toil will prompt the user to decide whether they want to publish workflow metrics, and, if it thinks it can get ahold of the user, will not proceed until they decide or a timeout elapses.

CWL

• Add caching to toil-cwl-runner. Use --cachedir [dir] to enable, and avoid rerunning previously cached jobs. (#4298)
• Add CWL badges to documentation (#5183)
• Improve error message when a file is not found in CWL (#5174)

Misc

• Toil will no longer select GPU or high-priority Slurm partitions when it does not need to. (#5223)
• Allow handling unlimited number of jobs on Slurm (#5064)
• Add hack to automatically un-stick jobs that can be un-stuck by lsof. (#5214)
• Re-added support for --time in TOIL_SLURM_ARGS (#5230)
• Added --slurmPartition and --slurmGPUPartition options for manual Slurm partition selection. (#5231)

8.0.0

Highlighted Features Added

• toil debug-job now has --retrieveTaskDirectory <dir> which will set up a job's downloaded files under <dir> and try to stop the job after doing the downloads. Jobs can call self.files_downloaded_hook() to provide a stopping point for this mode. (#4815)
• toil debug-job can now reconstruct the inside-the-container environment for CWL and WDL tasks. (#4815)
• Added support for caching on Slurm and other HPC schedulers (#4775)
• Replace all instances of boto2 with boto3 for all Toil AWS code (#4718)
• Add support for Python 3.12 (#4718)
• Add support for Python 3.13 (#5145)
• Ceph input/output errors from file locking functions are now tolerated. (#4874)
• Toil now uses flock to enable directory locks to work properly (#4924)
• Added support to get Slurm partitions and automatically send jobs to GPUs on Slurm (#4833) (supports both CWL and WDL)
• New --symlinkJobStoreReads=False option lets you force local-node copies (possibly in the cache) even when reading directly from a FileJobStore is possible, potentially reducing shared filesystem IO. (#4673)
• Toil now supports reading and writing MiniWDL's call cache. (#4797)
• Toil now supports running CWL and WDL workflows from Dockstore, by using either a Dockstore page URL or TRS ID as the URL/filename of the workflow to run. Since these often contain ? or #, remember to quote them on the command line! (#5049)
• Add support for parallel file imports (#5114)
  • New argument --importWorkersThreshold. This specifies the threshold where files will begin to be imported on individual jobs. Small files will be batched into the same import job up to this threshold.
  • --importWorkersDisk defaults to 1 MiB. Should be increased when download streaming is not possible on a worker.

• Toil now has a --slurmDefaultAllMem option to run jobs lacking their own memory requirements with Slurm's --mem=0, so they get a whole node's memory. (#4971)
• toil-cwl-runner now has --no-cwl-default-ram (and --cwl-default-ram) to control whether the CWL spec's default ramMin is applied, or Toil's own default memory logic is used. (#4971)
