 +
** Update conda recipe (pyqt4 restriction for now)
 +
* Interpreter
 +
* Release
 +
* Integration
 +
** hard to build same type of GUI in other apps that integrate core VisTrails (tend to use just the API)
 +
** independent pieces of the GUI could be reused if they were more independent.

'''Updates'''
 +
* [DK] meta-vistrail work
 +
** Extend Vistrail to MetaVistrail to support meta-actions

 +
 +
'''Updates'''
 +
* [DK] Testing UUID/SQLAlchemy branch
 +
* [DK] Working on meta-versions
 +
** would be nice to have pipeline and vistrail separate
 +
** [RR] Then do we only have meta-actions, any change to the pipeline is a meta-action that adds a version that does the change?
 +
** [DK] Yes?
 +
* [RR] Notebook interface (Vizier) making good progress, figuring out cell outputs
 +

 +
 +
'''Items to Discuss'''
 +
* [RR] How to specify an "intermediate output" that should be presented to the user, from any module? (useful for notebook interface)
 +
** Can designate in module description an output port
 +
** Value has to be serializable
 +
** Should use the OutputModes work to handle multiple modes, configuration, selection, ...
 +
* [RR] Is VisTrails with SQL usable concurrently?
 +
** [DK] Probably not, demo from [TE] exists

 +
 +
'''Updates'''
 +
* [RR] Added a looping indicator on modules [https://github.com/VisTrails/VisTrails/pull/1217 #1217]
 +
** This makes it easier to understand what's looping, no need to follow edges and count
 +
* [RR] Refactoring CLTools for integration in Docker package
 +
* [RR] Will try to refactor autogenerated package logic next (need to update TensorFlow package for TF 1.0, should really be using this)
 +
 +
'''Items to Discuss'''
 +
* [RR] Problem with vtkRendererToSpreadsheet output mode: does it's own ModuleConnector handling, interfering with looping/streaming logic, to add the module ID on the renderers [https://github.com/VisTrails/VisTrails/issues/1216 #1216]
 +
** Can we move this up to the renderer modules?
 +
** Thankfully RR couldn't find much of this madness in the rest of code (outside of controlflow and parallelflow)
 +
 +
=== February 24, 2017 ===
 +
 +
'''Updates'''
 +
* [RR] Rich-text module documentation ([https://github.com/VisTrails/VisTrails/pull/1210 #1210])
 +
** Went over packages and fixed format; maybe we should have a test to validate RST?
 +
* [RR] Single-instance shutdown with <tt>--remote-shutdown</tt> ([https://github.com/VisTrails/VisTrails/pull/1204 #1204])
 +
* [RR] Bundle installation not super reliable; probably need to go in and add checks for every usual environment
 +
 +
'''Items to Discuss'''
 +
* [RR] There are issues with list-depth
 +
** Some VTK ports marked with depth=1 don't actually accept multiple inputs (vtkDataSetMapper)
 +
** Issue with looping groups

'''Items to Discuss'''
 +
* [RR] Collaboration with school of medicine to port HiC-bench to VisTrails
 +
** Have homemade workflow system based on R scripts and symlinks
 +
*** Each steps has multiple sets of parameters
 +
*** Submits PBS jobs for each step with each set of parameters, using PBS job metadata to wait on previous step
 +
*** Gets all results in directory structure <code>step3-parameters/step2-parameters/step1-parameters/files</code>
 +
** VisTrails improves provenance capture and makes editing pipelines easier
 +
*** Need better support for aggregation (groupby operation might be good enough; pandas?)

 +
'''Items to Discuss'''
 +
* [RR] Working on single instance code for MARIN ([https://github.com/VisTrails/VisTrails/pull/1205 #1205])
 +
** Remote shutdown ready ([https://github.com/VisTrails/VisTrails/pull/1204 #1204])
 +
** Still improving it
 +
** Want to return something more structured to the client (success/fail code, stdout, stderr)
 +
** Should be usable without Qt
 +
* [DK] Shutting down VisTrails has issues: cleans up interpreter (to remove files) but also resets persistent pipeline for no reason
 +
* [DK] Working on batch execution using console_mode
 +
* [DK] Settings aliased parameters when using core.api?
 +
 +
=== November 16, 2016 ===

'''Updates'''
 +
 +
* [RR] Issue [https://github.com/VisTrails/VisTrails/issues/1200 #1200] from @samtux: need to set PyQt to API version 2 before ever importing it; using require_pyqt_api2() does that (also can install bundle)
 +
 +
'''Items to Discuss'''
 +
 +
* Email from Pieter: executing pipelines with parameters from command-line using single-instance
 +
** Seems to work, main instance gets full command-line and alters configuration temporarily
 +
** Not sure what his error is (VisTrails returns little information in a lot of cases); though execution error should return something more meaningful
 +
** Actions:
 +
*** Can add switch to kill main instance
 +
*** Can improve single-instance code to return more meaningful errors + machine-readable output from "client" VisTrails
 +
*** Add client/server code to <tt>core</tt> that doesn't use Qt? Also need a run.py-line entrypoint that doesn't use gui (calls console mode like <tt>gui.application.VistrailsApplicationSingleton#noninteractiveMode()</tt>)?

* New version 2.2-2 of Debian package, still [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=796994 wrong copyright], and [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=748692 broken bundle installation]
 +
** Finally replied, says copyright issue will be fixed soon, working on including VisTrails 2.2.4 for Debian Stretch
 +
* Working on Docker package, low hanging fruit because we have CLTools, and useful for some workflow (also step towards CWL support)

* command-line input parameters to provenance
 +
** [DK] we don't create a persisted workflow from those input params, i think
 +
** [DK] these are already defined as aliases so we treat them differently form a normal input param
 +
** [DK] still have the potential problem of allowing a user to view the workflow as it was run with a given set of aliases
 +
** Do the vistrails variables values get stored in provenance? (what if values change?)

 +
 +
'''Updates'''
 +
* [RR] Went over vgc.poly.edu/vistrails.org config:
 +
** Added TLS certificate (vistrails.org, www.vistrails.org, lists.vistrails.org, vgc.poly.edu and a few others)
 +
** Fixed usersguide scripts (won't disappear again)
 +
** Moved some websites over to HTTPS
 +
** [https://docs.google.com/document/d/18YZewjR2YY9cQ9pzdA-nU9jbu2L7jYcPlDi3iaPadwA/edit Websites]
 +
* [RR] users' guide on readthedocs: doesn't seem like we can have both the internal docs ([http://vistrails.readthedocs.io/ currently there]) and users' guide under the same RTD "project"
 +
* [DK] UUID support almost complete (use-uuid branch), bundle translation then fits more easily on top of that
 +
 +
'''Items to Discuss'''
 +
* [RR] Move www.vistrails.org (wiki) to HTTPS? There is a trac at https://www.vistrails.org/
 +
** Get rid of more services? (svn, trac, ...)
 +
* [RR] Notebook execution works. How do we support more languages (than Python)?
 +
** Need: detection, metadata reader, code to input values
 +
* [RR] ALPS and VisTrails 2.1 issue: should be using 2.2?
 +
 +
=== August 17, 2016 ===

* [TE] Matplotlib and sklearn are exportable using module-to-script api
 +
* [TE] Need to add to_python_script to pythonfunction.py to get bokeh and numpy export working.

* [TE] Python Wrapper and scripting
 +
** All changes merged into python-wrapper branch
 +
*** Tests pass
 +
*** Still need to update sub-branches
 +
** Minor fixes
 +
*** vtkPlot3DReader upgrade bug
 +
*** Added tuple exporting
 +
** Most of vtk examples can be exported [https://gist.github.com/rexissimus/5ac7374cde8525d84f9443f019d234e2 example]

* [TE] Wrapper patches now stored as [https://github.com/VisTrails/VisTrails/blob/python-wrapper-script-patches/vistrails/packages/vtk/vtk_wrapper/vtk_patch.py python code]
 +
** Connection variables now lowercase
 +
** Can we use code as output variables?
 +
*** E.g. "vtk_dataset_mapper.GetOutput(0)"
 +
*** Could mutate output when output method is only supposed to be called once
 +
*** Need to be able to rename output port as python code(e.g. when there are 2 "vtk_dataset_mapper"s)

 +
** [https://github.com/VisTrails/VisTrails/blob/python-wrapper-script-patches/vistrails/packages/vtk/vtk_wrapper/parse.py#L135-L273 Example of new patches]
 +
** Legacy '.vtkInstance' is now added as a patch "self.vtkInstance=self" (see new patching example)
 +
** [https://github.com/VisTrails/VisTrails/blob/python-wrapper-script-patches/vistrails/core/scripting/api.py New api for executing standalone modules]
 +
*** Accessing module was disabled for core/api, but a different api for this is probably better anyway.
 +
*** api.Package now gives [https://gist.github.com/rexissimus/f0d6b026aa5a2a770847f3321744645d#file-new_patching-py-L26 directly callable module compute functions]
 +
*** Only works on modules not using interpreter functionality ('.interpreter', etc.)
 +
**** for zip file modules and others that need temp files and use the interpreter for this, need to modify the module, but could work around with python libraries for managing temp files
 +
** Fixed more renaming issues - [https://github.com/VisTrails/VisTrails/blob/python-wrapper-script-patches/vistrails/core/scripting/scripts.py#L63-L64 function argument names should not be replaced]
 +
** Still need to do something nicer for the patch formatting
 +
*** patch keys currently contain non-python-variable characters but this can be fixed
 +
*** Need to replace string template with python variables that is replacable using RedBaron
 +
**** Patches could then look like:

'''Items to Discuss'''
 +
* [TE] New patch method for python-wrapper [https://gist.github.com/rexissimus/009b303e4cadcd4b8f2fec6cf848cb2b example]
 +
** A patch is a string template with self/input/output variables for patching a class method
 +
** Patches are stored in xml specification
 +
** Patches are assigned to methods in ClassSpec's
 +
** Used both for execution in vistrails and when exporting as script
 +
*** Executed with "exec" when run in vistrails
 +
*** Turns patches into natural calls in script
 +
** Wrapping VTK library no longer needed
 +
*** Removes ".vtkInstance" (Automatically removed from PythonSources and vtkInteractionHandlers)
 +
** Removed fix_classes.py (Subclassing of VTK classes to patch methods directly)
 +
** Also used for port translations (With patch names like "basic:Color#input") (No more ugly input_t method definitions)
 +
** TODO's
 +
*** Add to export_as_script
 +
*** Patch Modules that represent Python functions as well

** Preludes (imports) still need improvements
 +
** Works with vtkInteractionHandler (clipping plane)
 +
** Resulting clipping plane is incorrect? (supposed to hide one side of the plane)
 +
** vtkRendererOutput Uses VTKRenderWindow as output
 +
*** Should support different output modes?
 +
*** Does not work with multiple outputs (Next cell is displayed when current is closed)
 +
*** Uses wrapped vtkInstance (as vvtk)

-
*** Basic type is List, since most types are array_likes.
 
-
*** TODO: More classes and functions
 
-
*** Some operations are in-place and some aren't, and docstring not super clear
 
-
*** [RR] It seems only methods mutate, and most have a numpy.xx function equivalent; just manually go through the methods and remove the mutating ones?
 
-
** Class wrapper is modular
 
-
*** Docstring parser and type string parser can be customized
 
-
*** Classes can have optional attribute/method ports
 
-
**** Inspectors and attribute/method modules can be created separately
 
-
** Use PythonCalc as an example
 
-
*** Can be re-implemented as a function with a parseable docstring
 
-
*** [RR] PythonCalc is just an example, and it might actually make sense to get rid of it, or do a proper math package with scalar operations (as separate modules, no combobox)
 
-
** [RR] TensorFlow to use wrapping as well

*** Very simple (only types 'tensor' & 'variable')

** Pipeline execution no longer makes the interface hang, it just makes the kernel hang (but that's fine)
 
-
** We can use notebooks as modules (probably way nicer than the PythonSource module)
 
-
** We can run multiple kernels so long as the ports carry things that are serializable

** [RR] argues that modules are still good; UV-CDAT shouldn't move towards a purely script-based backend
 
-
** [RR] export/import with Python could reduce a lot of that friction by allowing 1) to edit workflow as Python 2) to open up boxes automatically if needed code doesn't match actual modules

-
** Missing some libs (scikit-learn, tej, tdparser, SQLAlchemy+connectors
 
-
** Windows: runvistrails.py is no longer used, so the PATH is wrong
 
-
** Windows: pip is broken, but it probably wouldn't work anyway because of permission issues (disable this?)
 
-
* Queries, upgrades and getPipeline() usage ([https://github.com/VisTrails/VisTrails/issues/1054 #1054])
 
-
** Getting a pipeline with getPipeline() is not safe: it might return an invalid pipeline
 
-
** This is used in many places throughout the code, like queries
 
-
** Upgrading would require going through the controller, but that creates new actions
 
-
* [TC] Avoid copying a module's output if it's used as input by exactly one downstream module ([https://github.com/VisTrails/VisTrails/issues/1060 #1060]) (useful for big numpy arrays you can update in-place)

* Upgrade issue: [https://github.com/VisTrails/VisTrails/issues/1017 #1017]
 
-
** Automatic upgrades should happen between versions of provided upgrades
 
-
** Our existing upgrades work around this so it doesn't need to be 2.2.0
 
-
* Corner-case VTK modules
 
-
** No longer need VTKCell input port, so don't interfere with registry and API anymore
 
-
** Still work weirdly, people probably shouldn't use them
 
-

* [RR] Switching order of output ports ([https://github.com/VisTrails/VisTrails/pull/1006 #1006])
 
-
** added port specs are sorted at a separate spot (Module.*_port_specs properties) than those in the registry (which are sorted in the registry), but those two lists are just combined without respect to sort keys
 
-
** need to determine whether the two lists should be merged or remain distinct
 
-
** should make sure that order of input ports and output ports makes parallel connections for things with same order
 
-
** DK suggests breaking backward compatibility here: workflows still run, can fix easily if a problem in an existing package.
 
-
* [RR] Question about output modes ([https://github.com/VisTrails/VisTrails/pull/1007 #1007]), how to integrate in API ([https://github.com/VisTrails/VisTrails/pull/24 #24])

-
** need to test this
 
-
* [TE] vtk wrapping
 
-
** Mostly finished
 
-
** VTK 5.10 produce incorrect results with old wrapping
 
-
*** Old wrapper is based mostly on VTK 4
 
-
*** Most vtk_examples affected
 
-
*** [http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Replacement_of_SetInput]
 
-
*** should be able to upgrade from SetInput to SetInputData (need to drop GetOutput and replace with self ports)
 
-
*** can we change vtkInstance to just return self and not wrap things
 
-
** terminator example not working under 5.8?

* How does VTK wrapping fit into general wrapping framework?

* [TE] VTK wrapping
 
-
** [https://gist.github.com/rexissimus/16b74693545b5e7c1035 Benchmarking vtk package]
 
-
*** Old: 24.7 seconds
 
-
*** New: 10.5 seconds (Except first time that adds 8 sec)
 
-
**** The parsing that calls is_abstract (that tries to instanciate all vtk classes) is now only run the first time.
 
-
**** get_items_from_sigstring takes 2 seconds, maybe we can use a lookup dict for already computed sigstrings?
 
-
** Now using a general python function wrapper
 
-
*** VTK classes are wrapped into python function that does not depend on vistrails
 
-
*** VTK functions can be executed without vistrails
 
-
*** The spec maps functions into vistrails modules, but can also describe wrapping
 
-
*** A general python function wrapper that supports
 
-
**** kwarg inputs
 
-
**** single, list, dict outputs
 
-
**** callback for progress reporting
 
-
**** temporary file generator for using FilePool
 
-
**** optional output generation
 
-
*** Creating specs:
 
-
***** Create spec by hand
 
-
***** Auto-create spec outline (TODO) and manually finish it
 
-
***** Dynamically create spec (VTK)
 
-
***** Implement documentation wrappers (Can use scikitlearn wrapper to wrap numpydoc) (TODO)
 
-
***** Classes as bad functions needs to be wrapped in new functions before they are wrapped. This is different for each package.
 
-
****** Classes is hard: Like VTK, and matplotlib. Scikit-learn does still not wrap classes
 
-
***** Spec diffing and patching could be done using code from matplotlib.
 
-
** Still needs upgrades from old VTK package
 
-
*** Is it possible to dynamically wrap functions, e.g, you see a SetFunc and just remove the 'Set' prefix. Or do you need to create a complete mapping?

* [TE] VTK wrapping
 
-
** Dynamic loading works
 
-
** Reading XML is fast enough, but [https://gist.github.com/rexissimus/8272d3c776ccfa115d82 unserializing data is slow]
 
-
** Working on patterns for patching
 
-
** Matplotlib has many advanced patterns like argument ordering, nested arguments, alternateSpecs, output types.
 
-
*** Having all this in a general wrapper might confuse users?
 
-
** [RR] Delay module (except for identifiers) until you need it---e.g. don't deal with port specs, etc. until necessary
 
-
* Scripting Support [https://github.com/VisTrails/VisTrails/pull/950 #950]
 
-
** [RR] Issue with getting code from modules
 
-
** Design a simple solution
 
-
** [JF] Couldn't you use modules as black boxes without conversion, just to call into modules/subworkflows easily from e.g. IPython?
 
-
*** [RR] This is a job for the API, and a very separate use case. See [https://github.com/VisTrails/VisTrails/pull/24 #24]

* Wrapping
 
-
** Format to use? Currently XML (like current matplotlib)
 
-
*** JSON and YAML have simple "to python dictionary" methods
 
-
*** But don't stream
 
-
*** YAML a lot easier for humans
 
-
** [DK] vtk-new-package also changes parameter names, creates enumerations
 
-
*** intermediate schema needs to be extensible
 
-
*** packages will want to store there specific infos for compute() method generation
 
-
*** also might have specs-altering info, like matplotlib's alternateSpec
 
-
** representation to code , registry already has schema for some aspects
 
-
** [RR] We might want to see if Module subclasses can be created lazily
 
-
*** no need to create all the classes just to register them in the registry and never actually use most of them
 
-
*** future effort
 
-
* [RR] Where should VisTrails packages live?
 
-
** tej installs as 'vistrailspkg.tej', TE installed it as 'userpackages.tej'
 
-
** Currently, standard packages are 'vistrails.packages.', user packages are 'userpackages.' and packages loaded through pkg_resources might be anything
 
-
** [RR] Use 'vistrailspkg.' everywhere?
 
-
** Long-term effort to simplify package distribution/installation (and have VisTrails get them automatically?)

-
* [TE] New VTK wrapping
 
-
** Current code by DK seems a good deal faster
 
-
** Generates XML that can be patched/tweaked, generates Python code from it, VisTrails only loads generated Python code
 
-
** RR would rather have VisTrails load intermediate representation (= XML) directly, wants to make sure this is not slower
 
-
** The goal is to turn the intermediate step into something generic that would be used for every wrapped package (vtk, numpy, matplotlib, sklearn, java) instead of each having its own
 
-
** TC has its own code at [https://github.com/Nikea/VTTools/blob/master/vttools/wrap_lib.py github:VTTools] which parses numpy docstrings and generates modules, doesn't yet handle classes or persist anything
 
-
* Web crawler
 
-
** Right now, TE starts jobs for "start crawler", "stop crawler", "install classifier"
 
-
** RR would rather have the crawling be a job as far as VisTrails and tej are concerned
 
-
** The whole thing would be one pipeline: load examples, train classifier, start crawler [check for job, kill previous one, upload model, start processes], get snapshot, visualize
 
-
*** Need some support in tej and job submission system: long-running jobs, stop a job (wait for it to finish?), restart a job even though results are cached

    • Update conda recipe (pyqt4 restriction for now)
  • Interpreter
  • Release
  • Integration
    • hard to build same type of GUI in other apps that integrate core VisTrails (tend to use just the API)

June 28, 2017

Updates

  • [DK] Testing UUID/SQLAlchemy branch
  • [DK] Working on meta-versions
    • would be nice to have pipeline and vistrail separate
    • [RR] Then do we only have meta-actions, any change to the pipeline is a meta-action that adds a version that does the change?
    • [DK] Yes?
  • [RR] Notebook interface (Vizier) making good progress, figuring out cell outputs

Items to Discuss

June 7, 2017

Updates

    • Can designate in module description an output port
    • Value has to be serializable
    • Should use the OutputModes work to handle multiple modes, configuration, selection, ...
  • [RR] Is VisTrails with SQL usable concurrently?
    • [DK] Probably not, demo from [TE] exists

  • Bundles & DB Code
  • Interpreter
  • Merge / Versioning Version Trees
  • Python3
  • Workings of List
  • Packages: Wrappers + new Versions (VTK7)
  • Script Conversion

    • would be useful for both workflows (run to a particular checkpoint)
    • and useful for notebook interfaces
  • SQL backend: does it allow for concurrent access?
    • Yes, real-time collaboration work for concurrent single vistrail access
    • Should be able to access different vistrails at once without issues

Updates

Items to Discuss

March 8, 2017

Updates

  • [RR] Added a looping indicator on modules #1217
    • This makes it easier to understand what's looping, no need to follow edges and count
  • [RR] Refactoring CLTools for integration in Docker package
  • [RR] Will try to refactor autogenerated package logic next (need to update TensorFlow package for TF 1.0, should really be using this)

Items to Discuss

  • [RR] Problem with vtkRendererToSpreadsheet output mode: does it's own ModuleConnector handling, interfering with looping/streaming logic, to add the module ID on the renderers #1216
    • Can we move this up to the renderer modules?
    • Thankfully RR couldn't find much of this madness in the rest of code (outside of controlflow and parallelflow)

February 24, 2017

Updates

  • [RR] Rich-text module documentation (#1210)
    • Went over packages and fixed format; maybe we should have a test to validate RST?
  • [RR] Single-instance shutdown with --remote-shutdown (#1204)
  • [RR] Bundle installation not super reliable; probably need to go in and add checks for every usual environment

Items to Discuss

  • [RR] There are issues with list-depth
    • Some VTK ports marked with depth=1 don't actually accept multiple inputs (vtkDataSetMapper)
    • Issue with looping groups

Items to Discuss

  • [RR] Collaboration with school of medicine to port HiC-bench to VisTrails
    • Have homemade workflow system based on R scripts and symlinks
      • Each steps has multiple sets of parameters
      • Submits PBS jobs for each step with each set of parameters, using PBS job metadata to wait on previous step
      • Gets all results in directory structure step3-parameters/step2-parameters/step1-parameters/files
    • VisTrails improves provenance capture and makes editing pipelines easier
      • Need better support for aggregation (groupby operation might be good enough; pandas?)

December 14, 2016

Updates

  • [RR] Single-instance code: over-engineered, but will work
    • (Have to avoid race conditions on startup, and OSes offer very different locking primitives)

Items to Discuss

  • Email from Matt Dirks: combobox should work, ask for more code?
  • Email from marin.nl:
    • looks like they would benefit from new interpreter
    • how to store their consolidated provenance when they exchange .vt files around?

November 30, 2016

Updates

Items to Discuss

  • [RR] Working on single instance code for MARIN (#1205)
    • Remote shutdown ready (#1204)
    • Still improving it
    • Want to return something more structured to the client (success/fail code, stdout, stderr)
    • Should be usable without Qt
  • [DK] Shutting down VisTrails has issues: cleans up interpreter (to remove files) but also resets persistent pipeline for no reason
  • [DK] Working on batch execution using console_mode
  • [DK] Settings aliased parameters when using core.api?

November 16, 2016

Updates

  • [RR] Issue #1200 from @samtux: need to set PyQt to API version 2 before ever importing it; using require_pyqt_api2() does that (also can install bundle)

Items to Discuss

  • Email from Pieter: executing pipelines with parameters from command-line using single-instance
    • Seems to work, main instance gets full command-line and alters configuration temporarily
    • Not sure what his error is (VisTrails returns little information in a lot of cases); though execution error should return something more meaningful
    • Actions:
      • Can add switch to kill main instance
      • Can improve single-instance code to return more meaningful errors + machine-readable output from "client" VisTrails
      • Add client/server code to core that doesn't use Qt? Also need a run.py-line entrypoint that doesn't use gui (calls console mode like gui.application.VistrailsApplicationSingleton#noninteractiveMode())?

November 2, 2016

Updates

  • New version 2.2-2 of Debian package, still wrong copyright, and broken bundle installation
    • Finally replied, says copyright issue will be fixed soon, working on including VisTrails 2.2.4 for Debian Stretch
  • Working on Docker package, low hanging fruit because we have CLTools, and useful for some workflow (also step towards CWL support)

Items to Discuss

October 5, 2016

Items to Discuss

  • working toward a 3.0 release; project board
    • unique ids
    • bundles
    • GUI fixes
    • wrapping updates
    • python3
    • interpreter?
  • command-line input parameters to provenance
    • [DK] we don't create a persisted workflow from those input params, i think
    • [DK] these are already defined as aliases so we treat them differently form a normal input param
    • [DK] still have the potential problem of allowing a user to view the workflow as it was run with a given set of aliases
    • Do the vistrails variables values get stored in provenance? (what if values change?)

Updates

Items to Discuss

  • [TE] New patch method for python-wrapper example
    • A patch is a string template with self/input/output variables for patching a class method
    • Patches are stored in xml specification
    • Patches are assigned to methods in ClassSpec's
    • Used both for execution in vistrails and when exporting as script
      • Executed with "exec" when run in vistrails

    • Wrapping VTK library no longer needed
      • Removes ".vtkInstance" (Automatically removed from PythonSources and vtkInteractionHandlers)
    • Removed fix_classes.py (Subclassing of VTK classes to patch methods directly)
    • Also used for port translations (With patch names like "basic:Color#input") (No more ugly input_t method definitions)
    • TODO's
      • Add to export_as_script
      • Patch Modules that represent Python functions as well

June 29, 2016

Updates

Items to Discuss

  • [TE] Export VTK as python script
    • Works on Terminator (Isosurface, Volume Rendering, clipping plane, combined rendering) example
    • Preludes (imports) still need improvements
    • Works with vtkInteractionHandler (clipping plane)
    • Resulting clipping plane is incorrect? (supposed to hide one side of the plane)
    • vtkRendererOutput Uses VTKRenderWindow as output
      • Should support different output modes?
      • Does not work with multiple outputs (Next cell is displayed when current is closed)
      • Uses wrapped vtkInstance (as vvtk)
        • Create new patch system with code that can be used both in vistrails and in a python script?

June 22, 2016

Updates

Items to Discuss

  • [TE] Fix for upgraded analogies (PR #1177)
    • Uses module location to find module remap (The best we can do right now?)
    • Also fixes remapped port names for connections to existing modules
    • May still fail on complex upgrades like adding a function on an upgraded module that has a different port name
  • [TE] Working on exporting wrapped libraries (VTK)

June 15, 2016

Updates

  • [TE] Added depth logic to python script exporter (full commit)
    • Fully implements connection merging and list looping

Items to Discuss

  • [TE] Making analogy work on upgraded workflows (#1175)
    • Analogy only works We need to use the non-upgraded action chain
    • But pipelines need to be valid (matcher uses module portspecs)
    • Tried to get upgrade remap from upgrade action, but this seems impossible
    • Use module location instead?
      • Location should be identical for one-to-one module upgrades

June 1, 2016

Updates

  • VisTrails 2.2.4 announced (finally)
    • 5 survey replies
    • 47 downloads last week

Items to Discuss

  • [TE] Export VTK as script (python-wrapper)
    • to_python_script
      • needs the pipeline (or at least the connections)
        • Should not generate code for any possible VTK method (exporter detects which ports is used in the source)
        • VTK needs to know connection order
        • Adding functions directly to the script results in nicer code
    • Add support for multiple input connections
    • Add support for list looping

May 25, 2016

Updates

  • Mailing-list fixed
  • Getting stats from the "server news" mechanism (via parser)

Items to Discuss

  • [RR] Alexis doing writeup on VisTrails, curious about interesting streaming use-cases (and potential future users)
  • [TE] Union ports
    • Show union ports in pipeline (DEMO)

May 18, 2016

Items to Discuss

  • [TE] mailing list still down - Julio working on it
  • [TE] Improved union port
    • New schema 1.0.5 adds portitem.union string attribute
    • Works with pipeline view, parameter exploration view, and mashup view

    • Use with VTK ports?
      • It uses [item_1,item_2] style ports usually with different tuple length.
  • [TE] Remove emacs dependency from db generate #1173

May 11, 2016

Items to Discuss

  • [TE] Union type #1172
    • GUI-based solution Branch union-port Demo?
      • Shows single port for all ports with same sort_key
      • Select specific type when adding/showing
      • Only one type should be visible on the module at any time
      • Making tuple parameters union types is probably too complicated
      • Should work with alternate specs like matplotlib (if sort_key is defined correctly)
  • [TE] Feature suggestion: Let connections connect to functions/parameters
    • Show functions and parameters as ports and toggle port visibility directly for functions and parameters
    • Use separate views for ports and functions (like before)
      • Allow rearranging of functions
    • Pros:
      • Supports ordered connections. Create 2 functions, make them visible as ports, make connections to them.
        • We can also have, e.g., a line joining the ports on the module to indicate they are part of a list.
        • Makes List module simpler
      • Connect to parameter in tuple
      • Functions that are visible on the module can connect to an actual function, and not just to the first one it finds.
      • Can replace operation modules (in python-wrapper) in some cases for, e.g., numpy.
    • Cons:
      • Interface more complicated and crowded
      • More difficult for users to grasp?
      • No immediate use case
      • Makes no union type for tuple parameters a bigger problem.
  • [TE] Publish user survey?
    • No response from vistrails release yet
    • Not announced on vistrails-users yet.

April 27, 2016

Updates

Items to Discuss

  • [TE] Wrapping Bokeh
    • New method type "operation"
      • Transforms Figure->Glyph->Output into Glyph->Figure->Output
        • Glyph sets function name and arguments as output
          • Not serializable, but should always be computed together with the subject of the operation.
        • Figure applies Glyph operation on itself
      • Useful for matplotlib?
        • matplotlib currently find actors by searching upstream?
        • But this is more difficult since matplotlib is not function-based.
    • New "union" port type
      • Turns "x(float), x(list)" into "x (float, list)" and uses first set value
        • Uses only first value in tuple
        • Bokeh have many properties that support (list, string, Float)
      • Does not work with depth=1 types (e.g. Float of depth 1)
        • Turn Depth 1 types with known type into lists?

      • Updated all signals to new-style
  • If we go 2 to 3, this could break packages
    • means we should schedule any package format changes for the same time
    • e.g., imports should be unrelated to code path (function to load module from package identifier?) (take them out of vistrails.* #1002)
    • any structural changes (e.g. the __init__ versus init thing) (RR thinks it makes sense, though having both named "init" is unfortunate)
    • putting package identifier as xml?
      • Python not so bad, plus some stuff in there is Python code (checking dependencies)
    • version the APIs?
      • RR planning on versioning vistrails_module.Module, no point versioning the whole package?
  • file formats on 2 to 3:
    • no real translation/upgrade, but non-ascii values that work on 3 won't load in 2

Updates Items to Discuss

  • Updating VisTrails dependencies
    • Successfully built Win7-64/Python3/PyQt5/Qt5/WebEngine/VTK7
      • VTK 7 is the first supporting Python 3 but is only in release candidate phase.
        • Next version of VTK 6 is rumored to support Python 3
        • There is a development branch of VTK 6 supporting Python 3
      • Can travis build this?
        • We can skip tests for WebEngine and VTK if needed
    • Python 3 showstoppers
      • No MySQL-python (sqlalchemy supports mysql through other drivers)
      • No suds (there are active forks but we could also drop support?)
  • Options for python2/3 support:
    • Interpreter could be python2/python3 based on packages
    • six layer works but not the easiest to maintain (e.g. in reprozip)
  • Drop support for win-64
  • Update copyright headers to 2016
