Release Notes

Release Notes#

dev-branch#

  • Oct 7 2025: Allow to sort columns with --order option.

  • Oct 7 2025: New column type M (monitor), which prints useful information about running tasks.

  • Oct 7 2025: If the task is not using subworkers, the workers column no longer displays -0/1

  • Made tb merge stat to be a nice well formatted cross-tabulated table.

  • Merge statuses Diff and Status are now nice Enums

  • Add large file support, allow tb merge copy to take --lfs allowing expert users to symlink source or destination of various large files/file patterns.

  • Add release notes

  • Allow to run workflows both by specifying either file or the Python import path: e.g. tb workflow -m c2db.workflows.core.

  • Fix all mypy errors.

  • Add tb merge subcommand. This is a complete infrastructure bringing Taskblaster closer to distributed repository format. Users are allowed to merge repositories, which would be useful for example calculating parts of the project in different supercomputers or distributing work between users.

  • Move most of the Click options decorators to tb.cli.options module.

  • Allow to add columns to the default ls pattern. Now tb ls -co+ adds output to the default listing, instead of user having to copy paste tb ls -cosirITf.

  • Add --ready option which allows tb ls and tb run to select only tasks that are ready to run, e.g. tb run --ready "tree/*/results' . Very useful to quickly run result collecting tasks while other heavy calculations are still running. Previously, without --ready option Taskblaster would start also to run the unfinished heavy calculations which are ancestors of some of the results tasks.

  • Bug fix: Do not attempt to sync workers on read only repositories.

  • Add --workflow MODULE/FILE option to tb run and tb workers submit commands. This allows workers to automatically submit newly created work, and also procees with dynamical workflows when workers run out of work.

  • Add --rerun and --resubmit options to tb unrun. It is sometimes difficult to select the exact list which tb unrun utilizes, and to that end it is useful to perform immediate automatic tb submit or tb run command to those exact tasks.

  • Add tb special wait command, which is useful for automated scripts. It waits until there is no more work to be done.

  • When cleaning empty directories during tb unrun, always preserve the current working directory. This prevents users from getting a stale file handle.

  • Bug fix: Fix tb workflow --silent option.

  • Allow to set SPHINXBLASTER_TEMP folder to control the temporary folders upon building the documentation. Add better error messages when execution of taskblaster commands fail during the documentation building.

master branch#

  • Added documentation about how to connect multiple workflows How to connect multiple workflows?.

  • Updated external_file to external_data and allowed it to support also directories.

  • Added --no-remove option to tb unrun. Tasks that are created dynamically such that their existence depends on another task are normally removed when that task is unrun. This option allows to only unrun them.

  • Added --conflict-states option to tb unrun to allow to unrun only tasks which are in a confict state.

  • Added --filter-task=FUNCTION to tb unrun to allow filtering of tasks which should be unrun.

  • Added --only-descendants to tb unrun to allow only to run descendants of whatever trees are selected as the input.

  • Added tb special rename-object expert method to allow renaming of already serialized objects.

  • Added tb special amend expert method to allow a cheap way of correcting outputs of heavy tasks without having to rerun them.

  • Allow to create records of tasks whose ancestor tasks are not done.

  • Solve deprecation of sqlite3 default datetime converter

  • Bug fix: Initialize all tables when creating the repository (to allow to merge to empty repos)

  • Allow tasks to run with no MPI even though MPI is detected (useful for example for VASP and QE).

  • Add a Collect-class which helps to read results from finished Taskblaster trees.

Taskblaster 0.2#

  • Stable version, the taskblaster article is based on this version.
