Version 2.2.2

Released 19 July 2022

  • Fix jug cleanup when packs are used (jug pack)

Version 2.2.0

Released 4 May 2022

  • Add jug pack subcommand
  • Make get_tasks() return a copy of the tasks instead of the internal list. Technically, it is possible that this is a breaking change for some workflows, but returning the internal version was arguably a bug
  • Removed dependency on the six library as we no longer support Python 2.7.

Version 2.1.1

Released 18 March 2021

  • Include requirements files in distribution

Version 2.1.0

Released 18 March 2021

  • Improvements to webstatus (by Robert Denham)
  • Removed Python 2.7 support
  • Fix output encoding for Python 3.8
  • Fix bug mixing mapreduce() & status --cache
  • Make block_access (used in mapreduce()) much faster (20x)
  • Fix important redis bug
  • More precise output in cleanup command

Version 2.0.2

Released Thu Jun 11 2020

Bugfixes

  • Fix command line argument parsing

Version 2.0.1

Released Thu Jun 11 2020

Bugfixes

  • Fix handling of JUG_EXIT_IF_FILE_EXISTS environmental variable
  • Fix passing an argument to jug.main() function
  • Extend --pdb to exceptions raised while importing the jugfile (issue #79)

Version 2.0.0

Released Fri Feb 21 2020

User-visible improvements

  1. Jug can now keep track of failed tasks.

Use jug execute --keep-failed to preserve locks on failing tasks and jug cleanup --failed-only to remove locks from failed tasks. Similarly, jug status and jug graph now display failed tasks

This avoids the situation where a failing task (for whatever reason) blocks the rest of the process. It improves on jug --keep-going (which does the same) as with --keep-going, each new process will attempt to run the task. If the task reproducibly fails after a long period, this results in wasted computation.

  1. The exit environmental variable are now checked by default. Create a file called __jug_please_stop_running.txt in the current working directory and Jug will stop after it finishes the current task.

Bugfixes

  • Fix jug sleep-until in the presence of barrier() (issue #71)

Internal improvements

  • jug.backend.base_store has 1 new method listlocks
  • jug.backend.base_lock has 2 new methods fail and is_failed
