Updates
Items to Discuss
October 29, 2014
Updates
- [RR] Build scripts
- Tommy working on release scripts (updating version numbers in build scripts and splash screen)
- [TE] prepare_release.py updates version numbers, branch, hash, and splash (requires inkscape)
- sdist and wheel ("PyPI" packages) fully automated, have builder
- conda too, builder
- Windows build script needs lots of binaries in fixed locations, e.g. C:\Python27, C:\Users\vistrails\src\vtk, ... build difficult to reproduce
- could use conda here, but problems with the script
- Mac OS ???
- [TE] Built with "make_app"
- Needs installation of qt, vtk, etc., to build.
- Building usersguide should be more contained
- would py2app work on a condo-installed VisTrails?
- [TE] Built with "make_app"
- Tommy working on release scripts (updating version numbers in build scripts and splash screen)
Items to Discuss
- [RR] Weird error in UV-CDAT has me baffled (#843)
- [DK] check on packages.uvcdat (generic name, could be overloaded) and/or the Variable name (also generic, could be overloaded)
- [RR] JobSubmission and RemoteQ:
- some minor issues with the way things are stored, mostly because uuids and other items should be removed
- [RR] caching output values in the vistrails was not a good idea
- big issue is still that RemoteQ is not best solution
- keep mapping on server to map something in module (pipeline_signature) to job and output
- VT keeps track of which workflow submitted job
- start_job method just calls arbitrary line of code to start job
- github migration
- [RR] to send github an email to ask what the best method might be
- problems with terminator.vt example?
- potential interaction handler issue?
- vt using temporary directory to store files
- disk cleaners can wipe these directories (USGS reported)
- question is whether disk cleaners *should* be doing that...
October 24, 2014
RR and TE meeting about job submission & RemoteQ status in VisTrails
http://www.vistrails.org/index.php/JobSubmission
Summary:
- some details to be fixed in RemoteQ package
- job result cache shouldn't be in vistrail
- the RemoteQ library is a problem since Troels doesn't maintain it
October 22, 2014
Updates
Items to Discuss
- [TE] improve-vt-bundle
- lack of documentation
- two layers of serializers
- serialize in more on-demand manner
- does auto-save save everything
- database bundles: try to tie into sqlalchemy
- Github migration
- decide on how to move the open tickets
- 26 first issues are already used, can just add original ones
- Rémi needs access to the trac database (vistrails.org)
- if possible, move everything
- [TE] New 2.1 release to fix examples?
- upgrades had a bug so could affect existing (older) vistrails
- changes to script commands
- remove tilde files in release
- [RR] is release process automated?
- [TE] run scripts in the git repository
- putting release note inside vistrails
- TE to look into which steps are more difficult to change
- [TE] job-cache feedback?
- shareable jobs, but jobs are not persistent
- [TE] update Web Services examples
- look into RESTful services?
- should we deprecate the old examples?
- check the user's guide and edit if necessary
- [RR] VisTrails meant to written by developers and used by users
- writing packages is a bit hard
- developers want to use their own editors, specify which versions should be used
- still have to write your own wrappers
- if developers just want to integrate their tools, can be difficult
- get python program drag 'n drop into python source
October 15, 2014
Updates
- [TE] job-cache (merged)
- Store jobs in vistrail
- Fixed jobs in automatic loops
- [RR] Probably shouldn't be in VisTrails
- RemoteQ/BatchQ are nowhere to be found (except VisTrails's binaries), install procedure doesn't work, and unsupported
- Not really used by anyone else ("proper" job submission, e.g. clusters, use PBS/...)
- Sharing job status in vistrail is unsafe and WILL break if people make changes
- Having that in the vistrail XML for the next release would force us to support it/provide upgrade paths
- Suggest removing for now, while we think about this more
Items to Discuss
- (from last week)
- Use Github and pull requests?
- Have to find a way to import tickets from Trac
- Use a separate fork for UV-CDAT's vistrails?
- Check with Claudio
- Claudio says yes
- Use Github and pull requests?
- VisTrails and ViDA?
- Notes from meeting with F. Perez
- Use whole notebook as modules in VisTrails (don't necessarily need to deconstruct cells)
- IPython providing "kernels" (execution engine, behind notebooks) for 21 languages
- connect notebooks that are of different languages
- reduce serialization issues
- implicit if two notebooks need to move outputs into inputs
- They are discussing concepts of "notebook inputs" and "notebook outputs" right now
- Kind of like our mashups
- nbparameterise thread
- Inter-notebook interactions probably not envisioned (but they'd like to be able to point to VisTrails for that)
- [DK] interface workflow: how do users edit two different notebooks and connect in VisTrails (seems like a lot of windows)
- restrictions on what can be serialized? notebooks need to be serialized properly
- can you get a notebook without the stored outputs used by nbviewer?
- Using VisTrails workflows and capabilities from IPython
- Generic Python API + some rich text augmentations for the notebook
- Using VisTrails from notebooks using non-python kernels? IPC between kernels is not a goal for IPython folks
- Will try to follow their mailing-list and gitter
- Use whole notebook as modules in VisTrails (don't necessarily need to deconstruct cells)
October 8, 2014
Updates
- [TE] Store one job monitor per vistrail (almost done)
- Easier to share running jobs
- Jobs are shared between all workflows in a vistrail
- use new bundle structure
- what happens with local jobs?
- doesn't really make sense to open a job started locally on another machine
Items to Discuss
- [RR] Use Github and pull requests?
- BNL uses them, UV-CDAT switched to that to
- Development Branches is hard to keep updated and offers no categorization/sorting
- create pull request when new feature is started, do not have to wait until branch is completed
- Also, use separate fork for UV-CDAT's vistrails? UV-CDAT/VisTrails is marked as fork but can have a different set of branches
- vistrails.org might be the only UV-CDAT submodule that can't be served over https (see emails)
- user permissions?
- Juliana, thoughts on moving vistrails repository to github?
- need to keep testing 2.2 features (e.g. automatic looping, new widget interface) so we can prepare that release
- deprecation flag/error for old constant creation methods
October 1, 2014
Updates
- [TE] Graphicsview font issues solved
- Preventing DPI changes on windows and using fixed values for module size calculations
- Windows fonts always look bad

- constant-classes: get rid of dynamic generation, use metaclass for constant class
- version-flag: add --version flag back on argparse parser
- invalid-pipeline-hides-package-errors: switch to invalid pipeline and will try to fix it, handle upgrades
- actual error is not showed
- get into a deep recursion? upgrade to package and back
- [RR] JobSubmission package status (does it work? is it useful?)
- should be able to remove it
- [TE] different things to control batch job
- [TE] buidbot web interface got hung up
- [TE] New features in 2.2 release (please extend/update)
- [RR] New features? Maybe we should maintain a CHANGELOG file in the repository
- Inline widgets ready? Need to test
- output modules
- incremental change where we keep both cells and new output modules, then phase out output modules?

September 24, 2014
Updates
- [TE] rewrite-startup integration finished
- [TE] UV-CDAT bugfixes finished
- need to make sure that the Aashish and/or Charles are aware the changes have been made
- [TE] notification on github
Items to Discuss
- [DK] parameterExploration flag: just run the latest of the selected version
- may be nice to have a way to set parameters directly from the command-line like we do with output variables
- [RR] code issues found using pycharm
- there are a lot more issues than that, cf pylint
- use pycharm IDE or install pylint, pychecker to avoid committing basic mistakes
- [TE] QGraphicsView size issues between Linux/Mac
- the text size is different even for the same fonts
- matplotlib ships with three fonts
- has logic with rules to determine what the closest fonts
- Qt has global configuration that can be hard to override
- terminator example has 15 parameters that are editable (adds 20+ pixels and messes up layout)
- [RR] all tests pass on unicode branch
- will try to keep in sync
- [TC] lots of people with strange paths need to use
- [JF] back and forth with scripts
- cloud execution
- have more rules for certain environment
- simplify the interpreter, have a different interpreter
- create a new direction for a restrictive environment
- have documentation for the best practices
September 17, 2014
Updates
- [TE] Fixed database from command-line, server mode, command line flags
- [TE] Fixed slow view switching
Items to Discuss
- [RR] unicode and python3 compatibility
- [TC]
Pull request doesn't change any behavior (text_type, or str) - [TC] Many changes from py3 were backported to py2, no 2to3 conversion
- difference between text strings (always unicode) and byte strings (which are the default in py2)
- six.text_type which on py2 aliases to str and on py3 aliases to str (runs through unicode object initializer)
- make sure to import unicode_literals from __future__
- [RR] more complicated than that. Let's convert everything to unicode in one go, and fix issues
- [RR] issues with XML (de)serialization, locators, enum, configuration
- look at a 2.2 release before adding unicode support (unicode may need a while to work bugs out)
- [RR] don't move on Python 3 before unicode is supported. Probably no need to bring in six right now
- [TC]
- [TE] Parameter Widgets (function-tooltip) ready to merge
- LOD error
- [DK] improve-vt-bundle branch
- db/services/bundle.py exists on its own, need to link rest of code to use bundles
- sql-alchemy waiting, work on bundle first
- [TE] adding command-line options to the documentation, update in one place now (used to have pdf and HTML)
- [RR] Version flag missing in new startup, branch to add back, but argparse messes up the formatting
- [RR] Trying to load the same package twice or different versions of the same package breaks VisTrails
- [CS] Hire a couple of people for UV-CDAT, need someone to bring them up to date
- think about projects for them
- [DK] we are not sure the direction UV-CDAT will take after 2.0 release
September 10, 2014
Updates
- [RR] Backported tabledata package: https://github.com/remram44/tabledata-backport
- [TE] GUI Improvements
- Added type checking in parameter view
- Switch to workflow info when no module selected
- Improved fitToView (used a square setting?)
- [TE] Edit widgets
- Hide when zooming out
- Improved proxied widgets
- Improved selection border
- Profiling
- Nothing major for edit widgets
- Fixed mark_list_depth calls when switching versions
Items to Discuss
- Workflow longevity: mta example no longer works
- Fernando suggested offering an option that saves the package (or a description of the package) together with the workflow
- [DK] I agree, this had been talked about with the generic bundle support
- [TE] Everything stored in a zipped vt file, could also store to a directory
- [DK] some support for this
- [DK] to look over old code and point out what needs to be done for bundle support
- [RR] maybe work to distribute packages independent of VisTrails (or at least make moving between versions of packages easier)
- [RR] VisTrails integration with ReproUnzip: https://github.com/ViDA-NYU/reprozip/issues/69
- [DK] possible to do python install using smarter package installers?
September 3, 2014
Updates
- [TE] Fixed 1.0.3 schema and log upgrades
- [TE] Make sure that 1.0.3 has the right items across versions
- Keep startup only in master since it is only needed for upgrades
Items to Discuss
- [TE] Edit widgets demo
- don't show name of port for constants
- boolean widget doesn't look great (still native widget)
- different layout on Linux than Mac/Windows due to font?
- [DK] UV-CDAT build:
- Linux build and check for scipy issue (#590)
- python3?
- [TC] Good way to wrap up userpackages?
- using conda package manager (environment has directory and hard-linked into, need to be able to hard link into environment)
- [RR] is working to do a standard python package to recognize these automatically
- For userpackages, can configure userPackageDirectory to point to a hard-linked environment
- Preferences -> Paths & URLs -> Local Packages Directory
- everything to be in a "bubble" at BNL
- [ED] Parameter exploration:
- one variable that I care about but plot as 5x3 not 15x1 or 1x15, enhancement request
- [ED] Series of Qt widgets wrapped into VisTrails modules
- subclass SpreadsheetCell, Qt widgets use matplotlib
- [ED] to provide a demo on what is going on trac
August 27, 2014
Updates
- [TE] VisTrails 2.1.4 released
Items to Discuss
- UV-CDAT Bug #520 and #557: make sure we don't show errors for packages that don't load (put these at info level)
- [RR] already created a branch with this name
- matplotlib and UV-CDAT: should be able to include freetype in binaries
- Bug 886:
- merge in this branch, perhaps not 100% ideal but still better than what we had
- problem is that you sort of want to be able to do a bunch of actions and then raise InvalidPipeline so you don't have to do multiple try-catch
- Bug 892:
- not pythonic to forceably squelch propagation
- should be a configuration option to do this
- add a filter to the root logger so that VisTrails messages can be controlled
- will think about this more
- [TC] blocker on python3 compatibility?
- [RR] unicode support should probably be done first: unicode from all the files, weird casts everywhere in the code because we used Qt before api v2
- from future unicode literals and str type makes the right thing happen on 2 and 3?
- BNL really wants 3 support, willing to work on
- Issues are #673 (unicode) and #674 (python3)
- Relayout programmatically?
- layout_modules() in controller
August 20, 2014
Updates
- [TE] Parameter Exploration bugfixes
- "Create Version" spreadsheet button fixed
- Missing date attribute in xml caused errors
- Issue opening vtl links
Items to Discuss
- [RR] Pending branches:
- [TE] New bugfix release? - Parameter Explorations and wrong usersguide in Mac binary
- [TE] Module edit widgets demo
- start with tooltips for type names rather than showing them right now
- give warnings on input validation -- add to trac (#898)
- [Thomas] matplotlib is meant to be used the other way
- [RR] problem: this is not the way our other plotting packages work (including VTK: data -> data -> renderer -> cell)
- [RR] we've already released a matplotlib package (data -> plots -> figure -> cell) and can't really turn it around
- [RR] we all agree that current code is hacky (but works), see #685 then #396
August 13, 2014
Items to Discuss
- [TE] FileOpen event on Mac (#889)
- We can pass argv to QApplication

July 30, 2014
Updates
- [DK] UV-CDAT animation, sql-alchemy branch update
Items to Discuss
- [TE] parameters in workflow - demo
- show functions on mouse_over
- move set functions to the top
- inline parameter widgets
- show/hide all
- toggle in ports list to show/hide these widgets
- API design wiki page
- vistrails.api versus vistrails.core.api
- API is currently stateful, would like to change
- API calls using module names, parameter names instead of ids
- tighter integration with iPython (what were ideas from meeting last year with iPython devs)?
- argparse mutually_exclusive_group bug
- provenance viewer: make panel wider
- parameter views: combo box with different parameter viewing types
- change parameter not updating GUI
- installing python packages into binary
- modules that dynamically configure their ports
July 23, 2014
Updates
- [DK] output-modules merge, uvcdat, improve-vt-bundle
Items to Discuss
- API design wiki page
- [TE] output-modules feedback
- Can we have 'Output' module that uses input value to determine output?
- [DK] Unsure what this means, we could have more than one input port, seems like the mode of output is independent of what the value is
- [RR] Infer from python types would take a lot of work, explicit easier to understand
- Usability vs. issues for developers
- Hide all but value port for outputmodules
- Unsure here
- Make output mode be an enumeration rather than text entry (actually need to allow own entry)
- Should vtkRendererOutput replace VTKCell?
- [DK] Need to see if display views are involved, interaction handler, etc.
- Use module name as base name?
- Also naming for parameters on command-line here
- if you name module "flower", default base name is "flower"
- Also consider possibly only generating one output based on this type of naming
- Global imageFile format setting not working?
- Put on trac
- Created WebGL output for vtkRenderer (As empty package)
- Matplotlib WebAgg and MBAgg backends better for web
- Clash between mode identifiers
- Register this on trac
- [RR] how to load a specific mode if it isn't loaded? How do we find it?
- Can we have 'Output' module that uses input value to determine output?
- [TE] other ideas
- See other workflow systems: http://imgur.com/a/xY37B
- Add icons to modules (graphical representation)
- Add module by double-clicking in the pipeline view and writing module name
- Edit parameters directly on the module
- First step: move set parameters to top of list (or make more visible)
- Second step: mine to find commonly used parameters
- Better use of hovering to provide module information
- Show parameters on right
- [JF] Inspect workflows in the same window
- [DK] matplotlib feedback from Thomas Caswell
- figure top-down?
- see Tom's github fork of matplotlib of pyplot changes
- declarative syntax (MEP 25), goal for 1.5
- create artists in modules
- [RR] export-as-script
- It's mainly about renaming variables, to connect module and avoid collisions
- Currently gets code for script using package-provided to_python_script methods
- Using the redbaron library for this (under early development)
- Need to handle the different types of input corresponding to different calls (get_input, get_input_list, force_get_input, ...)
- [BNL] Adding new palette tool
- search box with many fields to format query, send back dictionaries
- [BNL] Use numpy docstring format? yes
- [BNL] PEP whitespace? yes
- [BNL] python3 compatibility? no a big priority right now
- [BNL] PyQt new style connections: yes
- [BNL] Access to vistrails.org repository? yes
July 16, 2014
Updates
- [TE] VisTrails 2.1.3 released
- [DK] UV-CDAT
Items to Discuss
- Integrate patches from github
- we push from vistrails.org to github
- git fetch git@github.com:VisTrails/VisTrails.git +refs/pull/17/head:refs/heads/pull17
- git checkout master
- git merge pull17
- git push origin master
- Synchrotron needs tools for computational pipelines
- Discussion on scripting support
- we are going to have to support a set of restricted operations
- readability versus parsing
- blocks vs. functions
- layered API:
- scripting api is base, interactive api has convenience methods that use state
- design document on API, wiki page?
- Other requirements for scripting
- higher-level operations to find results linked to certain provenance
- vt bundles
- should we look into improve-vt-bundle and sql-alchemy branches?
- design this (configurable bundles)
- have some hooks to add files to the vt bundle already
- move-dist-directory branch
- conflicts with python build directories
- does this affect build machines?
July 11, 2014
Updates
Items to Discuss
- Claudio wants to make it easy to edit PythonSource without VisTrails
- [RR] Dropping url-encoding would allow you to edit them from XML? But they are also quoted because used in <parameter val="..."/>
- Scripting support
- Export workflow as standalone script:
- Modules could provide their own logic, or we can make something up from compute() ast in some cases
- Also, add annotations to script to make it easy to reconstruct (and module IDs, so we can update)
- Read back script as workflow
- General case is hard
- Building PythonSources from blocks might be doable
- First step: simply reading some parameters from some modules in annotated script (i.e. has module ids)
- Export workflow as standalone script:
- IPython notebook integration
- Wait on output-modules branch; then we can show visualizations in notebook
- API needs work
- API calls need to return things (to put them in notebook)
- Make initialization easier (shouldn't need to create application, etc)
- Currently stateful! (
app.new_vistrail(), ..., api.save_vistrails(f)
instead ofvt=Vistrail(), ..., vt.save(f)
) - Should probably be in vistrails package directly
July 9, 2014
Updates
- [TE] Added logging of parameter explorations
Items to Discuss
- [TE] Crash when adding String module on Mac #760
- Updated binary to Qt 4.8.6
- Release 2.1 with Qt 4.8.6 to fix String module crash
- [TE] Table cell - Use HTML cell and D3?
- Interactivity for free
- Can it work over multiple cells?
- Will work directly on web and crowdlabs
- [Claudio] Scripting support
- VisTrails is general but does not interact well with other systems
- What is not working, how can we make it easier?
- Need ability to work without the GUI
- Construct workflows using utility functions that does not use the VisTrails GUI
- Convert python script to/from vistrails workflow
- Show PythonSource contents in script
- Start with workflow that do not show stuff at spreadsheet
- TODO:
- Design a better mechanism to integrate VisTrails with other tools, starting with Python
- Provide the ability to save a workflow in a format that can be edited using a text editor -- for example, save a workflow and use an editor to change the contents of the Python Source boxes in the workflow
- Provide functionality similar to what was implemented in UV-CDAT, where workflows can be used as black-boxes from Python. See slide 41 in http://uvcdat.llnl.gov/media/pdf/VisTrails_UV-CDAT_course.pdf
- For which applications would scripting support be useful?
- Look at max and grasshopper3d
- Claudio wants to test how parallellization works in VisTrails
- How would scripting support work?
- Meet on Friday
- Design a better mechanism to integrate VisTrails with other tools, starting with Python
July 2, 2014
Updates
- [TE] List handling improvements done
- Now List ports can connect to anything
- Only exception is List<->Variant
Items to Discuss
- [DK] List/Variant bug: #871
- [TE] Fixed
- [TE] Why is Map output a Variant?
- looks like this was done because Fold produces a Variant (makes sense since fold can be a sum), but Map should always be a list)
- this will allow depth 1 input ports to connect
- [RR] added List.head as depth 1 port
- add documentation for this new functionality
- [DK] QPipelineScene.current_pipeline, controller refs #869
- [DK] PythonSource crash? #760
- update Qt for newer binaries?
- pyside support?
- Also, see #737
- [TE] Log Parameter Exploration? #870
- Very simple to enable, but we should annotate cell info
- [DK] tabledata pandas support?
- investigate on best way to make this available (data types, scripts, modules)?
- [JF] SIGMOD: python is becoming lingua franca for data analysis, munging
June 25, 2014
Updates
- [DK] master merged into output-modules
Items to Discuss
- [DK] Global configuration settings for output-modules when using inheritance:
- Example: Allow different file.suffix='.dat', imageFile.suffix='.png'?
- For an individual output module, we only have one setting since imageFile derives from file, but how should this work if we a global setting for moduleA=vtkRendererOutput and moduleB=FileOutput?
- decided that overriding for specific subclases makes sense
- [TE] automatic-looping
- get_input now merges all connections when depth>0
- Typechecking now respects configuration flags - fix for float/int reverted
- Issues with allowing List<->"Type of depth 1" conversions
- Treat list as Variant of depth 1
- List->Variant need to be treated differently otherwise it would loop over the variant
- wouldn't be able to do implicit looping over List/Variant because we don't know what the list depth of incoming list objects?
- [RR] matplotlib issue: log doesn't reflect the actual execution
- can we update logging provenance here?
- other packages (VTK) have similar issues since the renderer actually causes some of the upstream internal modules to do computations.
June 18, 2014
Updates
- [TE] Chris is using BatchQ
Items to Discuss
- [TE] automatic-loops-changes
- Mixing 0 and 1 depth types now works

- [DK] list of depth 1, can we pass a list here
- exception of List input port type?
- will this work? allows only
- [TE] numpy types in matplotlib?
- e.g. different float types
- workaround for numpy for List types already
- what about adding other types later? how would a package developer do this?
- Converter modules could work here but add more modules? hide the extra modules?
- Unify type checking that occurs over connections (controlled by settings) and Loop/depth type checking method (now in vistrails.core.modules.vistrails_module)
- [RR] depth 1 port going to List head port
- [TE] variant for (float, integer) tuple
- [RR] multiple connections into a depth-1 port only use one of the values
- should we have a self.get_input_list(flatten=True) option?
- [DK] output-modules: should work on so we can merge

- check in the old commit logs and/or trac to figure out what the old problem was
- [RR] Rolling out conda packages: anyone has experience with Anaconda?
May 28, 2014
Updates
- [DK] rewrite-startup close to stable, fixed issue with going back and forth from v2.1 (trying to resolve package config settings issue), means output-modules is close, too

- [TE] IPython console now shows <STANDARD OUTPUT> before printing from stdout/stderr
- [TE] Vistrail variables fixed
- Deleting a module with a variable did not remove the variable from the workflow
- Copying modules with variables now works
Items to Discuss
- [RR] Do not run modules upstream of submitted job
- jobs-use-signatures: Uses the subpipeline signature to identify jobs
- works: if job is submitted, check it without running upstream (we don't need the parameters this time(?))
- doesn't work in Map
- jobs-use-signatures_/connect-folded-module
- create a connection from folded module to InputList upstream
- looped module can run upstream if it needs, else we don't
- problem: the Map still needs the list, for length and type-checking
- Could we rearchitect the looping behavior? Basically, just copy the pipelines and run them with each entry from the loop
- Provenance could expand
- [RR] module-upgrade-recursion status? (not yet merged)
- [DK] to look at and merge (should be done)
- [DK] UV-CDAT Issues: #407 and #408
- [RR] Thumbnail comparison bug: different references are selected on master and dont-use-modules-as-data! (pipeline results are identical) Problem with upgrade code?
- using different reference images
- [TE] to look at
- look at the console_mode, how it gets back the upgraded version id
- filed as #831
- [TE] Vistrail variables
- Normally only one hidden module exist for each vistrail variable, but pasting a module with a vistrail variable will create a new hidden module. This does not break anything, but should be taken into account when modifying the code.
- When a vistrail variable module is created, an input named "value" is created. A bug with default values gave it the value "None". This is fixed. To make validation of existing vistrail variables work we need to check if the value is "None", but this would not allow "None" as a string.
- [DK] to look into this, we cannot have "None" there.
- [JF] NSF Big Data proposals (due in June)
- uuid status
- need to check tests and features outside of normal execution

- same package for local cluster and aws? Yes, but need to change two lines, path to configuration files on server
- could config files be set in a module instead or in the preferences?
- directories are hardcoded in hadoop package, need to be parameters
- anything that can change in different installations should be parameters

Jan 29, 2014
Updates
- [TE] automatic-loops - Groups and Multi-level looping now works
- [DK] matplotlib-add-helpers: Rework the semi-automatic generators
- [RR] java-pkg: bringing in old code, spreadsheet still works, probably going for dynamic generation of packages
- looking at jpype versus pyjnius
Items to Discuss
- [RR] str-format-module: in master. Merge in v2.1? Having to open the configuration window and click on a button is awkward
- [DK] watch out for dynamically created format strings, could cause inconsistency at compute time if the format string doesn't match the ports
- Go ahead to merge since similar problem with PythonSource
- What about using number of connections to enforce this? (set to 0 for config-style ports?)
- Streaming in VisTrails
- Q: how is parallelism working in VisTrails? A: both theading and multiprocessing, but separate branch
- for streaming, order of input and outut must be preserved
- module can generate a number of pieces, a module that collects needs to know when the stream ends
- need to preserve order of map operations and
- goal is to reduce the storage costs, want to make sure that we don't keep entire data in memory, don't generate the entire list at beginning
- hyperflow needs to know when a stream starts and when it ends: start and end token, hyperflow wraps data in a token
- Huy advises getting rid of the list and using tokens instead?
- interpreter can call compute-upstream and just tell interpreter to go upstream
- VTK streaming interpreter: might be in svn
- Remi: just be able to pass an object on the conection that knows the shape of the data and how to get next element (basically an iterator)
- where do we call get-next? module in the collector calls
- main advantage of streaming is being able to do aggregation during the compute (otherwise, we're doing map-reduce)
- the iterator encapsulates the calls to the module's compute
- issue with logging? already rewritten for parallel, should work here
- Examples: triangle_area, image histograms
- Slowdown caused by lists? colors? logging?
- Schema changes: need to record depth, what type of semantics for combining port values
- Also probably means that we don't pass just raw values, need to wrap with depth and iterator
- Issues Huy raised:
- issue with multithreading and streaming both enabled
- triangle with modules: need to be careful about order with items coming from two different modules (e.g. BuildTable in Rémi's example)
- UV-CDAT
Jan 22, 2014
Updates
- [RR] Branches to be merged in: reload-disabled-package (#714), ungroup-keep-disconnected-ports_/hybrid
- [TE] VisTrails 2.1.1 released
- [DK] matplotlib, uuid work
Items to Discuss
- [TE] Automatic Looping
- Using ListOf module as input will trigger the looping
- Runtime type checking because we don't have a ListOfT class for each type.
- [DK] USGS interested in working with this
- Add a merge module to make it clear where the iteration stops and ends
- Have different type of ports
- Remi to talk to Huy about streaming ideas
- can we detect the iteration and draw those modules differently
- decided that some fold/merge module would be useful, even if we don't always need to use it explicitly
- Using ListOf module as input will trigger the looping
- [RR] Ticking in matplotlib
- formatters, locators, tick scale

Jan 15, 2014
Updates
- [RR] improves-logging:
- Pass exceptions to it directly for single line, or traceback.format_exc() for traceback
- WARNING level now printed in the console by default, -V 1: INFO (log() calls), -V 2: DEBUG (debug() calls)
- Messages view now shows whatever is selected, no matter the console log level
- Python warnings get captured

- -> Yes, include in v2.1.1
- [TE] Hadoop package documented here: http://www.vistrails.org/index.php/Hadoop_Package
- [DK] UV-CDAT, LSU
Items to Discuss
- [RR] input-module-no-subclass: input ports of type 'Module' shouldn't accept any output? These are used for 'self'->controlflow module connections...
- controlflow modules have a function port that accepts a module
- check for modules that might use Module for something else
- suggestion is to use Variant for any type being supported (StandardOutput, List, others)
- warns for now (doesn't actually disallow the connection until next version)
- -> David wants to look at this more
- [RR] ungroup-keep-disconnected-ports: alternative ungrouping, keeps pipeline disconnected and preserves InputPort/OutputPort modules
- ideally, want to edit in place, could try to emulate the edit subworkflow code here, just have to save things back to the original vistrail
- -> hybrid approach, materialize the unconnected ports
- Bugfix release? Would solve issues with server and parameter exploration. (also, logging improvement?)
- [TE] Also fixes to workspace
- [DK] font issue for OS X 10.9
- Look at Java support in Java?
- can we leverage Rémi's past work here? on Weka

- issue with Jython is the interface
- also had java-based spreadsheet
- also look at moving VTK to a matplotlib style generation

- [DK] Work with USGS, refactoring version trees
Items to Discuss
- Colin's feedback on loops is that it has taken some time to wrap his head around what is going on
- what does Taverna do? automatically determines when a collection is being input and does iteration over the input and determines what output looks like
- look at what this would take, figure out what the best way to attack this (Automatic loops)
- Colin also asked about use of persistence in another module
