lsst-pipe-base v24.1.0 (2023-02-23)¶
New Features¶
QuantumGraph
now saves theDimensionUniverse
it was created with when it is persisted. This removes the need to explicitly pass theDimensionUniverse
when loading a saved graph. (DM-35082)Allow
PipelineTasks
to provide defaults for the--dataset-query-constraints
option for thepipetask
tool. (DM-37786)
Bug Fixes¶
Ensure
QuantumGraphs
are given aDimensionUniverse
at construction.This fixes a mostly-spurious dimension universe inconsistency warning when reading
QuantumGraphs
, introduced on DM-35082. (DM-35681)Fix an error message that says that repository state has changed during
QuantumGraph
generation when init input datasets are just missing. (DM-37786)
lsst-pipe-base v24.0.0 (2022-08-26)¶
New Features¶
Add the ability for user control over dataset constraints in
QuantumGraph
creation. (DM-31769)Builds using
setuptools
now calculate versions from the Git repository, including the use of alpha releases for those associated with weekly tags. (DM-32408)Improve diagnostics for empty
QuantumGraph
. (DM-32459)A new class has been written for handling
Task
metadata.lsst.pipe.base.TaskMetadata
will in future become the default metadata class forTask
, replacinglsst.daf.base.PropertySet
. The new metadata class is not yet enabled by default. (DM-32682)Add
TaskMetadata.to_dict()
method (this is now used by thelsst.daf.base.PropertySet.from_mapping()
method and triggered by the Butler if type conversion is needed).Use the existing metadata storage class definition if one already exists in a repository.
Switch
Task
to useTaskMetadata
for storing task metadata, rather thanlsst.daf.base.PropertySet
. This removes a C++ dependency from the middleware. (DM-33155)
Added
lsst.pipe.base.Instrument
to represent an instrument in Butler registry.Added
butler register-instrument
command (relocated fromobs_base
).
Bug Fixes¶
Fixed a bug where imported pipeline parameters were taking preference over “top-level” preferences (DM-32080)
Other Changes and Additions¶
If a
PipelineTask
has connections that have a different storage class for a dataset type than the one defined in registry, this will now be allowed if the storage classes are compatible. TheTask
run()
method will be given the Python type it expects and can return the Python type it has declared it returns. The Butler will do the type conversion automatically. (DM-33303)Topological sorting of pipelines on write has been disabled; the order in which the pipeline tasks were read/added is preserved instead. This makes it unnecessary to import all tasks referenced by the pipeline in order to write it. (DM-34155)
lsst-pipe-base v23.0.1 (2022-02-02)¶
Miscellaneous Changes of Minor Interest¶
Execution butler creation time has been reduced significantly by avoiding unnecessary checks for existence of files in the datastore. (DM-33345)
lsst-pipe-base v23.0.0 (2021-12-10)¶
New Features¶
Added a new facility for creating “lightweight” (execution) butlers that pre-fills a local SQLite registry. This can allow a pipeline to be executed without talking to the main registry. (DM-28646)
Allow
PipelineTasks
inputs and outputs to be optional under certain conditions, so tasks with no work to do can be skipped without blocking downstream tasks from running. (DM-30649)Log diagnostic information when QuantumGraphs are empty because the initial query yielded no results.
At present, these diagnostics only cover missing input datasets, which is a common way to get an empty QuantumGraph, but not the only way. (DM-31583)
API Changes¶
GraphBuilder
constructor boolean argumentskipExisting
is replaced withskipExistingIn
which accepts collections to check for existing quantum outputs. (DM-27492)
Other Changes and Additions¶
The logger associated with
Task
is now derived from a Pythonlogging.Logger
and notlsst.log.Log
. This logger includes a newverbose()
log method as an intermediate betweenINFO
andDEBUG
. (DM-30301)Added metadata to QuantumGraphs. This changed the on disk save format, but is backwards compatible with graphs saved with previous versions of the QuantumGraph code. (DM-30702)
All Doxygen documentation has been removed and replaced by Sphinx. (DM-23330)
New documentation on writing pipelines has been added. (DM-27416)
lsst-pipe-base v22.0 (2021-04-01)¶
New Features¶
Add ways to test a PipelineTask’s init inputs/outputs [DM-23156]
Pipelines can now support URIs [DM-28036]
Graph files can now be loaded and saved via URIs [DM-27682]
A new format for saving graphs has been developed (with a
.qgraph
extension). This format supports the ability to read a subset of a graph from an object store. [DM-27784]Graph building with a pipeline that specifies an instrument no longer needs an explicit instrument to be given. [DM-27985]
A
parameters
section has been added to pipeline definitions. [DM-27633]
