cleancommand now asks for confirmation when no targets are specified. This can be avoided by using the
The Slurm backend will now get all jobs from
squeueand not only jobs belonging to the current user. This used to be the default behaviour, but was unintentionally changed when refactoring the Slurm backend.
The output of the
cancelcommand is now correct.
This release is the first version of gwf to support Python 3.8. We’re now testing on nightly version of Python so that future Python releases should be supported as soon as they’re available.
Automatically checks for updates on a regular basis. A warning will be shown when a new version is available. This feature can be disabled with
gwf config set check_updates no.
The Slurm backend will now retry failed operations, e.g. if it fails to get the state of the queue from Slurm or if submitting a job failed.
Support for Python 3.8.
When running gwf cancel without specifying targets, only submitted/running targets will be cancelled.
Fixed a deadlock in the local backend which caused the workers to freeze.
Links to examples and ReadTheDocs (we’re now hosting the docs ourselves).
This release contains a few large features such as named inputs and outputs
and the introduction of the
Workflow.map method for easily generating
multiple targets from a template and improving readability.
There are also several minor improvements that contribute to the overall
user experience ranging from speed improvements for the
logs command to
improved debugging output.
The documentation has also been restructured and improved.
Named inputs and outputs. The
Workflow.targetcan now be either a string, list or dictionary. See the documentation for more details.
Tutorial now explains what happens if a target fails.
Documentation now has an official list of gwf plugins.
statuscommand now has a
--summaryoption the summarizes the status of an entire workflow.
All input and output paths are now checked for non-printable characters such as newlines and tabs. This can cause problems that are very hard to find and fix (e.g. gwf reporting that a file is missing even though it seems to be there). Paths containing such characters now result in an error.
logscommand is now much faster since it no longer builds the entire graph.
The target in the
statusoutput is now sorted in creation order, instead of alphabetically.
Cleaner output formatting, especially when running with
Improved log messages from scheduler when running with
-v debug. The messages are now more specific and helpful.
Documentation has been restructured to be more readable and have less redundant information.
Users can now run
gwf initto bootstrap a new gwf project (c78193).
Add option to protect output files in a target from being removed when
gwf cleanis being run (2f51ed).
Ensure job script end with a newline (#239).
Ignore missing log files when cleaning on run (#237).
Backend for Sun Grid Engine (SGE). The backend does not support all target options supported by the Slurm backend, so workflows can not necessarily run with the SGE backend without changes. See the documentation for a list of supported options.
gwf statuscommand now accepts multiple
-s/--statusflags and will show targets matching any of the given states. E.g.
gwf status -s completed -s runningwill show all completed and running targets.
A new command
gwf touchhas been introduced. The command touches all files in the workflow in order, creating missing files and updating timestamps, such that gwf thinks that the workflow has been run.
When specifying the workflow attribute in the workflow path, e.g.
gwf -f workflow.py:foo, the filename part can now be left out and will default to workflow.py. For example,
gwf -f :foowill access the
fooworkflow object in workflow.py.
Documentation describing advanced patterns for gwf workflows.
This release contains a bunch of new features and plenty of bug fixes. Most
noteworthy is the removal of the progress bars in the status command. The status
bars were often confusing and didn’t communicate much more than a simple
“percentage completion”. The status command now outputs a table with target
name, target status, and percentage completion (see the tutorial for examples).
Additionally, the status command now shows all targets by default (not only
endpoints). For users who wish to only see endpoints, there’s now a
We aim to make gwf a good cluster citizen. Thus, logs from targets that no
no longer exist in the workflow will now be removed when running
This ensures that gwf doesn’t unnecessarily accumulate logs over time.
Add missing import to documentation for function templates (4eddcac).
Remove reference to
Remove broken badges in README (e352f09).
Remove pre-1.0 upgrade documentation (bfa03da6).
Fixed bug in scheduler that caused an exception when a target’s input file did not exist, but the output file did (reported by Jonas Berglund) (92301ef3).
Dots have been removed from logging output to make copy-pasting target names easier (f33f7195).
Now uses pipenv to fix development environment.
Improved coloring of logging output when running with
Remove status bars in
gwf statuscommand (47cb7b50).
Added undocumented API which allows core and plugins to register validation functions for configuration keys. This fixes issues like #226 (c8c57d7c7).
gwf cleancommand now shows how much data will be removed (d81f143f1).
Remove log files for targets that are no longer defined in the workflow (beb912bd).
Note in tutorial on how to terminate the local workers (a long with other updates to the tutorial) (34421498).
Bug when returning an
AnonymousTargetfrom a template function without specifying the working_dir in the constructor (#212). Thanks to Steffen Møller-Larsen for reporting this.
Bug when using
--format tableand no targets were found (#203).
Bug when cancelling a target running on the Slurm backend (#199).
Link to documentation in error message when unable to connect to local workers.
Fixed bug in the FileLogManager where the wrong exception was raised when no log was found.
Moved checking of file timestamps to the scheduler. This means that creating a
Graphobject will never touch the file system, and thus won’t raise an exception if a target depends on a file that doesn’t exist and that’s not provided a target. Instead, unresolved paths are added to
Graph.unresolved. They will then be checked by the scheduler (if necessary). For end users, this means that many commands have become substantially faster.
AnonymousTargetwhich represents an unnamed target.
Targetnow inherits from this class and templates may now return an
AnonymousTargetinstead of a tuple.
Added backend.slurm.log_mode option, see the documentation for the Slurm backend for usage (#202).
Very slow scheduling when using dry run with unsubmitted targets (#184, 93e71a).
Fixed cancellation with the Slurm backend (#183, 29445f).
Fixed wildcard filtering of targets (#185, 036e3d).
Move file cache construction out of
Graph(#186, 93e71a). This change is invisible to end-users, but speeds up the
Made filtering more intuitive in all commands.
infocommand now outputs JSON instead of invalid YAML.
infocommand outputs information for all targets in the workflow by default.
Backends must now specify a
log_managerclass attribute specifying which log manager to use for accessing target log files.
Backends should now be used as context managers to make sure that
Backend.close()is called when the backend is no longer needed, as it is no longer called automatically on exit.
Added filtering of targets by name in the
Added API documentation for the
SlurmBackendto make it easier for plugins to integrate with Slurm.
Documentation for log managers.
Documentation on how to handle large workflows.
First stable release of gwf! We strongly encourage users of pre-1.0 users to read the tutorial, since quite a lot of things have changed. We also recommend reading the guide for converting pre-1.0 workflows to version 1.0. However, users attempting to do this should be aware that the the template mechanism in 1.0 is slightly different and thus requires rewriting template functions.

SlurmBackendwhich caused running targets as unknown (33a6bd).
The Slurm backend’s database of tracked jobs is now cleaned on initialization to keep it from growing indefinitely (bd3f95).
Fixed a bug which caused the gwf logs command to always show stderr (01b267).
Fixed a bug which caused dependencies to be set incorrectly when two targets depended on the same target (4d9e07).
Improved error message when trying to create a target from an invalid template (d27d1f).
Improved error message when assigning a non-string spec to a target (2aca0a).

Added a bunch of documentation (69e136, 51a0e7, 942b05).
Fixed bug in scheduling which was actually the cause of the incorrect scheduling that was “fixed” in 1.0b6. Also added documentation for
Updated documentation in a bunch of places, mostly styling.
