** For this to work need to complete relational support for Mashups (see ticket [https://www.vistrails.org/ticket/611 #611]). The code is in mashups branch and needs to be updated with the current master (it was branched from old schema-v1_0_3 branch and not updated since then).

-
** should we continue to maintain third-party packages (those in /packages not /vistrails/packages) or should these be moved?
+
-
*** do we distribute the /packages directory with the source tarball?
+
-
*** we don't want to be responsible for keeping these packages up-to-date, but at the same time, we shouldn't distribute packages that do not work with our releases...

 +
** 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.

* iPython-style faceted output:
+
=== August 2, 2017 ===
-
** iPython has a very nice feature where output can have multiple facets meaning the output in a command-line environment is different from that in a GUI environment
+
-
** Basically, an output is actually a dictionary where keys are mime-types and values is the corresponding output for that type
+
-
** A similar approach would be very useful for cases where we wish to run a VTK workflow that on the GUI appears in the spreadsheet cell but on the command-line generates a file, and in crowdLabs uses Wendel's WebGL solution
+
-
** That way, a user writes one workflow that runs everywhere
+
-
** I think the output dictionary should be mime-type -> function, however, as we don't want to produce all the outputs if we only need one at a time
+
-
** Could also have modules that lookup the output types and could be used for configuring output types.
+
-
** Should use the same cell names for output

* VisTrails: parallel and remote execution (Tommy will lead the discussion)
+
=== March 8, 2017 ===
-
** A way of running multiple workflows in parallel in vistrails
+
-
** Add support for cluster frameworks: BatchQ/Hadoop/MapReduce/Remote PBS
+
-
* Idea for parallel execution: use/extend the persistent sub-system so that "make-like dependencies" can be tracked. The spreadsheet should probably be avoided in the middle layers of such parallel executions.

-
** branch easy-install works on a Mac 10.7 and above using a binary built with python 2.7.2 (it's in tests area in sourceforge)
+
-
*** the problem is that py2app does not support setuptools and we have to use easy_install available on the system. We require python 2.7 and it is included by default on Mac only starting on version 10.7. If you install python 2.7 on 10.6 it will also work on that system.

+
** 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

+
-
*** When running VisTrails with the same interpreter used by easy_install, when enabling a package that supports easy_install, VisTrails will install it and enable it at runtime. This is using the same infrastructure to install python packages on linux systems but should work on any platform:
+
-
  rpy_dict = {'easy_install': 'rpy2',
+
-
                'linux-ubuntu': 'python-rpy2'}
+
-
  rpy2 = py_import('rpy2', rpy_dict)

* [DK] DataONE Package
+
* Email from Pieter: executing pipelines with parameters from command-line using single-instance
-
** [http://github.com/dakoop/vistrails-dataone GitHub]
+
** Seems to work, main instance gets full command-line and alters configuration temporarily
-
** Now supports uploading data to DataONE
+
** 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>)?

** It seems that we can't start an interpreter different from the one we are running. Does anybody know about this?
+
** [DK] we don't create a persisted workflow from those input params, i think
-
*** Because of the issue above, I couldn't execute system's easy_install from the VisTrails bundle
+
** [DK] these are already defined as aliases so we treat them differently form a normal input param
-
*** My solution would be to ship easy_install in the VisTrails bundle and use it when installing extra packages
+
** [DK] still have the potential problem of allowing a user to view the workflow as it was run with a given set of aliases

'''Updates'''
-
** I would like to ask if it is possible to build stand alone applications based on vistrails?
+
-
*** Emanuele will answer, we can, just not sure what example is best here
+
-
** To try and avoid reinventing the wheel, I am asking if anyone has developed, or knows of a development, of a "text" module.  By this I mean, a module that is somewhat equivalent to a String module, but capable of allowing the input of multi-line text in a very simple editor.  At this time, plain text is more than adequate (i.e. for handling configuration files, or multi-line test data), but the module should have the capacity to write out the data strings to file.
+
-
*** Tommy will answer, String type is not the problem, just want a subclass of String that can have the multi-line entry as its widget.  Also suggest having a WriteStringToFile module that writes to temp file (FileSink persists as normal).  Could submit a pull request to github.

* [FC] ParallelFlow
+
'''Updates'''
-
** ParallelFlow can execute a module (or a subworkflow) for different parameters, in different IPython engines (embarrassingly parallelism).
+
* [RR] Went over vgc.poly.edu/vistrails.org config:
-
** It is assumed that, in the machines where the engines are started, we have both VisTrails and IPython. Also, it is assumed that VisTrails is in PYTHONPATH.
+
** Added TLS certificate (vistrails.org, www.vistrails.org, lists.vistrails.org, vgc.poly.edu and a few others)
-
** If IPython engines are local, this means that different threads are created for each engine - these threads are automatically created by IPython. This is particularly useful for multicore machines.
+
** Fixed usersguide scripts (won't disappear again)
-
** IPython engines can also be created in a remote machine using SSH - this functionality still needs to be tested though.
+
** Moved some websites over to HTTPS
-
** Modules can now define serialize and deserialize methods in case they need to be retrieved from the engines (e.g.: 'self' output port). In this case, each module needs to define its own methods. For instance, VTK modules need to implement these methods using VTK's serialization routines.

'''Updates'''
-
* [DK] VisTrails packages
+
'''Items to Discuss'''
-
** Emanuele recently asked the py2app developers about making it easier to install other packages (and their dependencies into VisTrails)
+
* [TE] Python Wrapper and scripting
-
** Reply is here: http://mail.python.org/pipermail/pythonmac-sig/2012-October/023744.html
+
** All changes merged into python-wrapper branch
-
** I like the idea of having system-wide and local user vistrails directories for added packages
+
*** Tests pass
-
** This needs to be integrated with a much easier installation process.  Ideally, this looks something like:
+
*** Still need to update sub-branches
-
*** Users goes to package manager and clicks "Install Package".
+
** Minor fixes
-
*** We have a vistrails.org-based list of available packages that appears as a list.
+
*** vtkPlot3DReader upgrade bug
-
*** User selects a package and VisTrails determines any VisTrails, python, or other dependencies.
+
*** Added tuple exporting
-
*** We use setuptools or something like it to install the package and its dependencies into the local directories
+
** Most of vtk examples can be exported [https://gist.github.com/rexissimus/5ac7374cde8525d84f9443f019d234e2 example]
-
** Ideally, this also works for system-based python installs as well, this probably means separate python 2.x directories for VisTrails packages.
+
*** Sometimes connections are wrong, executing workflow sometimes works, otherwise copy/pasting is necessary
-
** Also, for "import vistrails" style use of VisTrails, it would be nice to be able to specify which packages will be used instead of relying on the ~/.vistrails/startup.xml settings
+
**** Could be a bug in the old vistrail, but not sure
-
** Potential issues include packages that use external libraries.  Can these also be installed into the package directories?
+
* [DK] Subworkflows and uuids
-
** Developer support: how does a developer build an installer for a more involved package (e.g. SAHM, ALPS)?
+
-
** [JF] VTK and such will be difficult.
+
-
** [DK] user-hosted packages
+
-
** how does this work for packages?
+
-
** Dave, Tommy, and Emanuele will meet on this
+
-
=== Oct 31, 2012 ===
+
=== August 3, 2016 ===
-
* [DK] scripting support (UV-CDAT)
+
'''Updates'''
-
** dependencies?
+
-
** allow scripting to automatically load dependencies
+
-
** GUI dependencies here:
+
-
** .vistrails clashes between scripting and GUI
+
-
* [JF] organizing workshop on reproducibility
+
-
** need to understand what is out there (actually how they work and fit into big picture)
+
-
** others will need to help with this
+
-
** proposals are out
+
-
* [TE] Added git access as: git://vistrails.org/git/vistrails.git
+
-
** this mirrors the http://vistrails.org/git/vistrails.git
+
-
** UV-CDAT wants access via http
+
-
** http access adds a /git subdirectoy
+
-
* [TE] Subworkflows on crowdlabs not working
+
-
** they are not stored in the database
+
-
** need to have a unique identifier
+
-
** could also copy to the .vistrails directory, possible name clashes
+
-
** in the long-term, nice to have vistrails access to database
+
-
* [BB] Added new uvcdat-next and uvcdat-master branches
+
-
** mirror the LLNL uvcdat development structure
+
-
** allows us to test new features in next before they go into master
+
-
* [BB] packages were failing on the UV-CDAT side
+
-
** shouldn't try and import package when package requirements are not met
+
-
** .uvcdat directory or a sub-directory of .vistrails (as a project-specific directory)
+
-
** [CS} don't do anything right now, need a stable release
+
-
** [CS] need a UV-CDAT workshop
+
-
* [BB] most of the remaining bugs are not crashing things, just annoyances
+
-
* [CS] get Fabio started on DAT
+
-
* [FC] ParallelFlow package
+
-
** execution in the engines not always working
+
-
** starting engines using ssh, could also use webdb machines
+
-
=== Oct 24, 2012 ===
 
-
* [ES] Update: Package distribution
 
-
** Installing extra python packages to be used in the binary
 
-
** easy_install configuration that installs in a custom folder in user's home directory
 
-
** worked for R, rpy
 
-
** possible issues with compiled things
 
-
** should work for all platforms
 
-
* [ES] New problem with rpy package (other than RVector)
 
-
** globalenv variable has changed--capitalization
 
-
* [ES] SourceForge VisTrails Project upgrade
 
-
** new features: https://sourceforge.net/p/allura/wiki/Features/
 
-
** do we just move everything to github?
 
-
* [FC] Parallel Flow
 
-
** Local controller and local engines are now started using VisTrails GUI (under Packages menu)
 
-
** Trying now SSH engines (IPython also supports MPI and PBS)
 
-
** Local controller needs to be stopped when VisTrails closes (in case user forgets)
 
-
*** if controller is not stopped, will have issues upon restarting because controllers are still there
 
-
*** cannot stop controller outside of vistrails
 
-
** Outer subworkflows are transformed into groups -- for inner subworkflows, needs to be recursive
 
-
*** problem is that the xml files that define the subworkflows cannot be found on remote machines
 
-
*** [DK} look for code that finds the subworkflows
 
-
** have an example, can test with Emanuele's new package idea
 
-
** have test workflow where module takes 10 seconds, executing 4 times with ipython also takes 10 seconds!
 
-
** execution logs from engines are being insereted into provenance
 
-
** machines are also being added for all engines
 
-
* [TE] posted issue on github with temporary directories, added configuration option
 
-
* [TE] crowdlabs executable workflows, external ALPS server is not accessible
 
-
** script to check external error
 
-
** string object not callable error
 
-
** one Titan workflow made non-executable
 
-
* [TE} check email addresses for github for the fixes/closes shorthand
 
-
* [BB] working on UV-CDAT issues
 
-
** checking on mountain lion build
 
-
** expects variables to be cdms variables
 
-
** how to handle all variables (python-based)
 
-
* [BB] Visit: no callbacks on the c++ side coming through, issue with linking to the correct global variables

'''Items to Discuss'''
-
* [FC] paraflow
+
* [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]
-
** New commit
+
** Connection variables now lowercase
-
** No more startup code
+
** Can we use code as output variables?
-
** Add start/stop menu options
+
*** E.g. "vtk_dataset_mapper.GetOutput(0)"
-
* [FC] Remoting package
+
*** Could mutate output when output method is only supposed to be called once
-
** Our solution cover this
+
*** Need to be able to rename output port as python code(e.g. when there are 2 "vtk_dataset_mapper"s)
-
*[BB] uvcdat calculator commands
+
-
** Need to talk to Emanuele about making this more robust, and what capabilities it should have.
+
-
*[BB] visit plugin
+
-
** Need to find how to access to methods used to implement the "isWorking" function originally created specially for the python VisTrails plugin
+
-
** Need to see if threading is still needed for the C++ version
+
-
=== Oct 10, 2012 ===
+
=== July 27, 2016 ===
-
* Update the People page: http://vistrails.org/index.php/People
+
-
** Also publications are likely out of date
+
-
* Mailing List
+
-
** Huy will check for anyone who signed up on the old vistrails-users list at SCI after we moved the list
+
-
** Then we can write Nick to shutdown the SCI list
+
-
* Remoting package:
+
-
** Terrence's solution: http://code.google.com/p/rpyc4vistrails/
+
-
** NASA and weather forecasting
+
-
* Parallel Execution
+
-
** Startup code in engines is possible (it executes a script before the initialization of the engines), but still not working. There was an [https://github.com/ipython/ipython/issues/2213 issue] before with it, that was apparently solved, but some other people still complained - waiting answer in mailing list
+
-
** Currently changing schema to add the notion of parallel execution
+
-
** Provenance capture:
+
-
*** make a new parallel execution entry, or
+
-
*** annotate that module was executed in parallel, can annotate each module execution with machine information
+
-
*** what about trying to determine which modules were tied to the same parallel execution
+
-
** Still going to look into serialization of some output values (e.g.: self)
+
-
** IPython shipped with VisTrails?
+
-
*** How big is iPython? 10-20 MBs
+
-
* Package distribution
+
-
** Ideally, users could download supplemental installers to add packages into binaries
+
-
** Hard to know which pieces belong to each package
+
-
** py2app selects only modules that we are using, hard to separate out particular packages
+
-
** could we tell py2app to install a full python distribution?

+
-
** discussion of interface improvements for supporting Jorge's workflows
+
-
* VisTrails and IPython

+
-
** If output port is an object (e.g.: self), serialize it and send it back?

+
-
** How engines should be started?
+
-
* website (www.vistrails.org)

** do we have access to the original illustrator? header
+
-
** documentation link should go to the current release sphinx documentation now? (even if not, the documentation page should point to the web version)
+
-
* [DK] MissingPackage errors: made to ignore module_id so we do not get duplicates

'''Items to Discuss'''
-
* No known items?
+
* [TE] Finished using patch in script [https://github.com/VisTrails/VisTrails/tree/python-wrapper-script-patches python-wrapper-script-patches]
 +
** locale?
 +
** [https://gist.github.com/rexissimus/f0d6b026aa5a2a770847f3321744645d new patching example] vs [https://gist.github.com/rexissimus/b28d83ae516a519167f5751bb8ab3739 old patching example]
 +
** [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:
-
=== Sept 12, 2012 ===
+
    def vtkInstance():
-
* Improvements to connection with CrowdLabs (see Dave's message)
+
        self.vtkInstance = self
-
** clean up interface
+
-
** currently using 2.0 on crowdLabs
+
-
** check into whether master can be translated back to 2.0
+
-
* Update on CrowdLabs + WebGL
+
-
** need some better documentation here
+
-
** examples in the user's manual would also be useful
+
-
** ALPS image resolution is not good, might be using the uploaded thumbnail
+
-
** seems not to be working right now
+
-
* Update on iPython and multi-threaded VisTrails
+
-
** each workflow would run on a different thread
+
-
** trying to serialize Module object
+
-
** example is executing Map concurrently
+
-
** pickling errors...
+
-
** can we push port values across only---do not need to pickle module
+
-
* Feedback from Jorge on his experience with VisTrails (and the remote job submission package)
+
-
** need some documentation on using the package
+
-
** how are the UV-CDAT instances going to be running on the cluster?
+
-
** want to push a workflow and run on a cluster
+
-
** sync up with Fernando and Huy's work
+
-
** would be good to have linked views support
+
-
** add initial support from Jorge's UV-CDAT work
+
-
* FIXED! mac_update_bin.sh is not working -- it does not delete the existing directories from lib/python_XY
+
-
* CLTools:
+
-
** Add reload button in the wizard window
+
-
*** does the new module reload? or do I have to delete the module and add a new one?
+
-
*** try to use the upload logic here
+
-
** Add a debug mode that shows how the command will be invoked -- this should help the users understand how CLTools work and to get a wrapper working more quickly
+
-
*** want to see what the command line would look like with the settings
+
-
** We should have more examples that cover additional features of command line tools, e.g.,  the use additional parameters such as a flag to specify an integer value. It would also be useful to show what the module will look like in VisTrails --- this will help users understand, e.g., what the "Visible" flag means.
+
-
** It looks like the ENV var is set for the CLTools package. But what if different modules need different environments?
+
-
** In the documentation, there is mention to file "suffix". Is this related to the exchange with Remi on June 14, 2012 4:14:32 PM EDT?

** Set up virtual machines?
+
-
** Do we need to buy a dedicated server for this?
+
-
*** [ES] It could be a desktop machine, with windows and mac installed. I don't think it needs to be a dedicated machine, but we would like it to be available when a binary is built. I think it could be a mac with windows installed as a virtual machine. A 64-bit Windows has to be installed. I believe Lion allows multiple users logged in the graphical system at the same time, so if it is a powerful machine, it can be used as the development machine for another user. Also, we need to make sure the vnc port is open to the outside so a remote user can connect to it.
+
-
+
-
** Running multiple Mac versions?
+
-
*** [ES] I am not sure if a binary built on Lion will run on Snow Leopard. The contrary is true, but then if we could run snow leopard as a virtual machine would be fine. It seems that Parallels only allows running the server version of Snow Leopard as a virtual machine. If we want to create a virtual machine of Snow Leopard, we need to do some hacking (some users were able to do this).

** GUI-based solution [https://github.com/VisTrails/VisTrails/tree/union-port Branch union-port] Demo?

* Preferences Dialog is modal and does not allow switch to error messages.

*** Shows single port for all ports with same sort_key
-
** Make preferences non-modal?
+
*** Select specific type when adding/showing
-
** May already be working non-modal...
+
*** Only one type should be visible on the module at any time
-
** Move "Module Packages" from Preferences to "Tools" window?
+
*** Making tuple parameters union types is probably too complicated
-
* Package identifier checks
+
*** Should work with alternate specs like matplotlib (if sort_key is defined correctly)  
-
** move the specific code for SUDS packages checks to the package itself
+
-
** add hooks to allow packages to identify which identifiers they can load

** Check names of ports to try to make these connections

** Issue: when there are multiple inputs that match multiple outputs (which connection to create)
+
-
=== April 25, 2012 ===
+
* [TE] Feature suggestion: Let connections connect to functions/parameters
-
* Persistent Package
+
** Show functions and parameters as ports and toggle port visibility directly for functions and parameters
-
** File management: discuss git-annex
+
** Use separate views for ports and functions (like before)
-
*** Issue with Windows support
+
*** Allow rearranging of functions
-
*** May work through cygwin, but written in Haskell which may lead to issues of integration in the Windows environment
+
** Pros:
-
** Make inputs of persistent modules read-only, to maintain consistency (only configure them through the configuration widget)?
+
*** Supports ordered connections. Create 2 functions, make them visible as ports, make connections to them.
-
** Reproducibility of workflows that have persistent inputs: get the version id from the log, put it in PersistentRef and execute the workflow?
+
**** We can also have, e.g., a line joining the ports on the module to indicate they are part of a list.
-
* Parameter exploration
+
**** Makes List module simpler
-
** Do we want to add named parameter explorations and multiple explorations per version? (Tommy)
+
*** 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.

'''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?
-
* Mashups in the database
+
* [TE] New bugfix release
-
** Matthias's error: is there an upgrade here?
+
** Finalize survey
-
** Mashups are not currently being saved in the database, Emanuele is fixing this

'''Updates'''
-
** Ticket on trac about schema changes

* Merged upgrade fixes
-
** Global variables: promote this to specified schema, not just annotations
+
** Now has infinite loop test
-
** Port cardinality: single input or multiple input guidance
+
** loop test now correctly loops 5 times
-
** What else should be updated in the schema?
+
*** remap_module used wrong (current) package version when creating ModuleDescriptor

'''Updates'''
-
* Proposal to change the interpreter to support suspended execution (Tommy will look into this and then coordinate with Troels)
+
'''Items to Discuss'''
-
** any module should be allowed to have its execution suspended --- we will have a new execution state
+
* [TE] Chaining upgrades done ([https://github.com/VisTrails/VisTrails/pull/1164 #1164])
-
** modules that are declared by the developer as suspendable will have a different shape (oval?)
+
** Replace "Upgrade" description annotation with "upgraded_from" annotation to identify which tags to hide?
-
** during execution, suspended modules are shown in a different color (orange?)
+
-
** VisTrails should execute all other modules that do not depend on the suspended modules
+
-
** the suspension of a module should generate a log entry that states the module is suspended
+
-
** Question: how often should VisTrails polls the suspended process? Should we have a 'resume' button in the interface to allow the user to also control this manually?
+
-
* Bug with updates (Dave will look into this)
+
* [TE] Iterating handle_invalid_pipeline ([https://github.com/VisTrails/VisTrails/pull/1165 #1165])
-
* export to stable menu  does not work, and we need a export to XML (Emanuele will add these to trac)
+
** Not based on [https://github.com/VisTrails/VisTrails/tree/chain-upgrades-loop chain-upgrades-loop]
-
* Crowdlabs and upgrades: Tommy and Wendel will work on this
+
** Cherry-pick test to preserve source?
-
* Emanuele is implementing support to export a single workflow. Caveat: the workflow will be detached from its original, and it will not be possible to 'update' it on Crowdlabs (this will be documented in the manual)
+
** Need maxPipelineFixAttempts option?
-
* Oracle interface: add dialog error msg when 'reproduce' is not possible; differentiate between execution and 'reproduce' (use italics for reproduce, and keep the existing colors)
+
*** The code is now smarter about recursion, so max attempts will "probably" never be reached.
 +
** Need [https://github.com/VisTrails/VisTrails/commit/0ef0667426937eddb1d1c1e397f0657ffec039a9 debug messages]?

'''Updates'''
-
* Matthias says: Troels has now found the time to finish his Python background job submission package, which can run calculations in the background locally, on remote Unix machines, and on remote clusters and supercomputers. We are integrating it into ALPS now and next want to do a VisTrails package for it. That should not be too hard, but we'll need some changes in VisTrails to be able to implement it well. If a background job starts we want to stop the execution of the downstream part of the workflow and can do that by raising an exception - but this exception should be treated differently to others. In particular we don't want to have the execution log record it as a failed execution, but maybe as "suspended" or "incomplete" or similar. One might also use another color than red to mark the status of the module and the downstream modules. Finally there might still be other branches of the workflow that could be executed and one does not have to stop all execution.

* [TE] Upgrades in Query Mode
-
** working on the release
+
** Now using code similar to do_version_switch
-
** hard to use VisTrails as a server because of the dependence on X server; when one does not need the GUI, it would be nice to transform the workflow so that it could run in batch, for example, use VTK offscreen support

*** Uses handle_invalid_pipeline
-
** caveat: requires VTK to be compiled with offscreen support

'''Items to Discuss'''
-
* new branch in crowdlabs for Wendel
+
* [TE] Fixing search mode
-
* update doc
+
** String query now matches all by default
-
* Oracle package
+
*** This caused pipeline queries to never match
-
* release 2.0 beta
+
** String query can search: User/Notes/Tagname/Time/Module name
-
* Future tasks: packaging, testing
+
*** Should we search module names by default? (Disabled by default because it is expensive)
 +
*** Fixed notes search
 +
** '>' parameter queries in documentation but has been removed
 +
** Fixed module matches for upgraded pipelines (By not upgrading pipeline)
 +
*** Upgrades still a problem
 +
*** Add "Upgrade all menu option?" (Or upgrade all on open when `hideUpgrades`)
 +
*** [JF] Allow search on past tags
-
* Update on crowdlabs (Wendel and Tommy)
+
* [TE] Create new bugfix release
-
** Wendel had problems with black images being returned by the VisTrails server, we suspect the issue is related to the virtual frame buffer---he will investigate

=== Oct 4, 2011 ===
+
-
 
+
-
* We will discuss issues related to remote execution of VisTrails modules as well as multi-threaded and parallel execution of workflows
+
-
* We will be joined by Matthias Troyer and Troels Frimodt Rønnow (ETH Zurich), Joel Daniels (NYU Poly), Marta Mattoso, Jonas Dias (UFRJ, Brazil)
+
-
* Terence Van Zyl and Derek Hohls (CSIR, South Africa) will not be able to make it today
+
-
 
+
-
We will develop a package that supports the ability to spawn a 'batch' job either on a local machine, a remote server, or a specialized cluster/supercomputer (with its own  batch submission system). The basic API will provide functions to:
+
-
* start jobs and obtain id (which will be saved in VisTrails and in UFRJ's database)
+
-
* poll the status of a job (if it is still running of it is completed)
+
-
* copy files to and from the remote server
+
-
 
+
-
Once a job is submitted by the 'remote module', the workflow stops. The user can poll the status through the UFRJ DB, or by running the workflow again on VisTrails. When the workflow is re-run, VisTrails will check the status of the job; if the job is still running, the workflow stops; if the job is complete, the files (if any) will be transferred and the execution of the workflow resumes.
+
-
 
+
-
Next steps:
+
-
* Troels will work with Joel on extend Joel's package to implement the basic API; and with Dave on implementing the idea of  'persistent jobs'
+
-
* Once the basic API is ready, we will work with Jonas to integrate his DB interface and the ability to access the provenance information about the remote jobs from multiple devices
+
-
 
+
-
 
+
-
* Tommy gave an update on CLTools. He already has a GUI to create the wrappers. He will make some additional changes and we will get some people to try it out.

=== September 27, 2011 ===
+
-
* Stéphane Descorps-Declere and Loic Couderc from [http://www.pasteur.fr/ip/easysite/pasteur/en Institut Pasteur] will join us
+
-
** Show demo of their package
+
-
** Discuss their specific needs
+
-
** How to deal with tools that have a large number of parameters and help the users not get lost setting these parameters, some ideas:
+
-
*** Port documentation in tooltips so mouse-over shows the documentation---need to support the specification of port-level documentation in the wrapper
+
-
*** Defining in the wrapper required and dependent ports. For the latter, define the dependency graph among the different parameters, and then use this information in the GUI. For example, given parameters A, B, C and dependencies C->B, B->A, and if A is defined, the GUI should require that B and C be set
+
-
*** Define in the wrapper port cardinality, i.e., the number of connections supported by the port
+
-
*** Support HTML-style documentation, which would allow the inclusion of images---the problem here is that it isn't good for command-line based use of VisTrails, so we also need to support plain text
+
-
** Stephane and his group will take a stab at implementing these ideas in two steps: first, making the required changes to the registry; and then, updating the GUI to use the new information that will be available in the wrapper.
+
-
 
+
-
* Discuss CLTools features/design
+
-
** Tommy has an initial function that parses man pages
+
-
** He will develop a GUI to help users wrap command-line tools---this will be a tool "separate" from VisTrails
+
-
** How to handle pre- and post-conditions? Could create scripts and wrap them using CLTools; or in VisTrails, use Python source
+
-
** reuse code from existing PythonSource GUI?  Maybe for pre/post-conditions, but the port list probably isn't a great interface for this.
+
-
 
+
-
* Issue with change_selected_version
+
-
** the graph is probably being corrupted by some version not being added to the version tree, could be a single action type
+
-
** Asked Tom if he knows steps to reproduce
+
-
 
+
-
=== September 20, 2011 ===
+
-
 
+
-
* Tommy will give a demo of CLTools package for wrapping command line tools
+
-
** Each tool creates a module, but modules cannot be versioned?
+
-
** Do you have specific tools/scripts I can try?
+
-
** Next step is to create more automatic wizards for tools and scripts.
+
-
 
+
-
=== September 13, 2011 ===
+
-
 
+
-
* Making it easier to wrap command line tools, motivated by the need to simplify the creation of executable papers
+
-
** Goal: build a wizard that guides a user on the creation of a wrapper.
+
-
** Assumption: the user has code that derived results for paper, and needs to package it in a way that reviewers can both reproduce and validate the results (e.g., try different parameter values)
+
-
** Initially, require the user to manually provide the information---parameter names and optionally, types.
+
-
** The output of the wizard should be a machine-readable specification which could be loaded as a module in VisTrails
+
-
** Some desirable functionality:
+
-
***ability to 'test' the wrapper; after the specification is input, show a vismashup-like interface for the user to set values, and allow him/her to execute the module
+
-
** provide 'smart' parsing to help in the wrapper construction, for example, extract the information from a python script
+
-
 
+
-
* We will create a separate branch for external developers, so that they can contribute patches to VisTrails
+
-
 
+
-
* David has cleaned up most of the GUI dependencies, the only remaining ones are:
+
-
** Notes associated with versions  (they need Qt)
+
-
** Generation of PDF representation for workflows and trees
+
-
** Thumbnails
+
-
 
+
-
 
+
-
* Web services (EMBOSS example)
+
-
** All now works except Prophet example (<choice> bug in SUDS). Should we remove it?
+
-
 
+
-
* Invalid modules (those in red) will not show parameters - Fixed
+
-
 
+
-
=== September 7, 2011 ===
+
-
 
+
-
* Query mode
+
-
** need to finish this implementation
+
-
 
+
-
* Analogy parent() issue?
+
-
** check what this was (form August 16)
+
-
 
+
-
* Web services (EMBOSS example)
+
-
** changes with SUDS (should be easier)
+
-
 
+
-
* VTK Examples:
+
-
** check old examples (don't seem to work with new version)
+
-
** these were auto-generated from VTK python examples a while ago and may have issues with newer VTK versions
+
-
 
+
-
* Auto-updating tags: migrateTags option in preferences
+
-
** Document this
+
-
** MIgrate notes as well so that the notes and tags are migrated
+
-
 
+
-
*
+
-
 
+
-
=== August 31, 2011 ===
+
-
* Diff tab has other view modes disabled.
+
-
** Opening a version or mashup from workspace, open in new tab instead of overwriting diff
+
-
 
+
-
* Binaries
+
-
** Matthias reported his tutorials were working with the current version
+
-
** Emanuele will start rebuilding the binaries more frequently again
+
-
 
+
-
* Mashup saving
+
-
** keep does not save
+
-
*** change the name keep to tag, to avoid confusion
+
-
** changes in workflows and mashups are reflected in the workspace now
+
-
*** still working on the executions
+
-
 
+
-
* Provenance browser
+
-
** instead of using version numbers for untagged versions, use the same convention used in pipeline view (eg., parent_tag + 1)
+
-
 
+
-
* Documentation
+
-
** VTK?
+
-
** At least a section in the user's guide  that points the users to the right examples
+
-
 
+
-
* Examples
+
-
** problem with examples that depend on 3rd-party packages
+
-
*** move them to the package folder?
+
-
 
+
-
=== August 16, 2011 ===
+
-
 
+
-
* Diff tab should have other view modes disabled.
+
-
** Tab doesn't make sense to switch back to history
+
-
** Could either try to make mode buttons work or just disable the modes
+
-
** Easier to disable the other modes
+
-
** If open a version or mashup from workspace, open in new tab instead of overwriting diff
+
-
** this way, a diff view is only closed by a user explicitly closing it
+
-
 
+
-
* Binaries for Mac
+
-
** Can build 64-bit binary and not 32-bit
+
-
** Emanuele will try to build 32-bit again
+
-
** ALPS has separate 32-bit and 64-bit versions
+
-
** Have two DLLs and registry for 2008 and 2010 Visual Studio
+
-
** Problem is that VisTrails may not run if the registry does not have the updates from Visual Studio
+
-
** 64-bit support allows more than 4GB of memory
+
-
 
+
-
* Should Mashups or Workflows be children if the vistrail in the workspace?
+
-
** Expand them automatically
+
-
** Mashups are meant to be shortcuts
+
-
 
+
-
* Mashup saving
+
-
** keep does not save (workspace is not updated)
+
-
** can we emit signal to workspace so it is updated
+
-
** can we put things in memory for the workspace?
+
-
** set_changed is called so we should update the workspace when a vistrail to be changed
+
-
 
+
-
* Subworkflows
+
-
** new changes to infrastructure to address distributed version control
+
-
** issue where multiple versions of the same subworkflow are listed
+
-
** multiple edits still an issue
+
-
 
+
-
* Analogies
+
-
** issue with parent() bug, Dave needs to file this
+
-
 
+
-
* Databases
+
-
** no direct database access currently allowed at NYU
+
-
** either create localhost database or use via crowdlabs
+
-

+
-
 
+
-
* Ticket #472.  Setting values in the user-defined list or any other type of window
+
-

+
-
 
+
-
* Subworkflows: edit bugs, Claurissa
+
-
 
+
-
* Groups inside of groups: currently cannot view them, Claurissa was looking at this
+
-
 
+
-
* Cmd-Q when the spreadsheet is on top seems to cause problems, need to force quit on the Mac.
+
-
 
+
-
* Enhancement: spreadsheet camera reset button?
+
-
 
+
-
* Cmd-E for configuring ports, Ticket #443 fix the old configuration windows or do away with, maybe keep this
+
-
 
+
-
* Parameter exploration: link spreadsheet to the parameter explorations, or display the parameters used with each cell, way to write
+
-
 
+
-
* Missing example for vtk.vt for cell locations and sheet references.
+
-
 
+
-
* Diff when upgraded doesn't work
+
-
 
+
-
* Upgrade entire version tree? How do we preserve tree structure?
+
-
 
+
-
* Mashups: display with pipelines? having both expanded to solve the extra click
+
-
** add this as a preference, other ways to view, add a button
+
-
 
+
-
* Opening a lot of vistrail files, closing them without saving, have "Yes to All", "No to All" buttons.
+
-
 
+

** Pipeline inspector may not get updated correctly when pipeline is empty
+
-
 
+
-
=== July 26, 2011 ===
+
-
 
+
-
* Zoom level in the first vistrail bug
+
-
** file on trac
+
-
** start vistrails and go to version view, history tree is not there, Cmd+R shows root node
+
-
** all vistrails after work fine
+
-
 
+
-
* Subworkflows
+
-
** issue with adding input ports and naming
+
-
** separate issue with editing a subworkflow more than once
+
-
 
+
-
* Analogies
+
-
** how to update the algorithm so the terminator with HTTPFile works correctly
+
-
 
+
-
* LaTeX Assistant
+
-
** Dave's new changes (read tex file and find \vistrails tags) moved to 2.1, remove from 2.0 for now
+
-
** Add back as a new feature for 2.1
+
-
 
+
-
* ungrabMouse in setModuleLabel
+
-
** probably happens on any module
+
-
 
+
-
* query issue: want to get back to original query from the search results and modify the query, currently just removes the query and resets everything
+
-
 
+
-
* keep triangle menu initially in 2.0, may remove in later versions if we can maintain access to all features

+
-
=== July <del>12</del> 13, 2011 ===
+
-
 
+
-
* Features added
+
-
** Display mashups in the workspace
+
-
*** Tommy added the support for the workspace, items need to be added
+
-
** Detach configuration window, rename, in a read-only, non-changing state (allow copy)
+
-
* Menu/Key shortcuts issues
+
-
** QBaseView window with menubar, add parts of menu
+
-
** QVistrailView inherits so we can reuse part of menus
+
-
** Need to show menus on Windows and Linux for other windows
+
-
** PythonSource has no menubar by default, can create its own menu
+
-
* Show Pipeline for a group
+
-
** delegate the creation of this window to QVistrailView?
+
-
** windows are set on show_group_function
+
-
** don't create a separate window
+
-
** eventually we should make groups logical not physical (so everything doesn't change each time to modify a group)
+
-
** just capture new pipeline
+
-
 
+
-
* spreadsheet editing and analogies
+
-
** add static methods to controller to allow general access to create methods
+
-
** need to factor code so virtual_cell can work with this code, too
+
-
 
+
-
* look into the issue when seeing a workflow for the first time; might be linked to upgrades and indexing
+
-
** Tommy should check that the exceptions are propograted
+
-
 
+
-
=== July 5, 2011 ===
+
-
* Server migration is almost completed
+
-
** GIT/Wiki/Trac working fine. Machine will be relocated to get better bandwidth
+
-
** <del>Still need to update vistrails.org to point to new location</del>
+
-
 
+
-
* Some bugs from last week were fixed, still a few more to go (see trac tickets)
+
-
* Minor issues raised at the meeting
+
-
** Add shortcut key for executing a pipeline
+
-
*** [ES] Ctrl+Return (Command+Return on a Mac) should work. The problem is that the shortcut does not show up on the Menu on a Mac. I've tested on QtDesigner and it doesn't show up there either. So it seems an issue with Macs.
+
-
** Being able to execute the selected node in Version View (having to open a pipeline just to execute it involve too many steps)
+
-
* Features to be implemented, then VisTrails will be feature frozen
+
-
** Display mashups in the workspace
+
-
** Detach configuration window, rename, in a read-only, non-changing state (allow copy)
+
-
 
+
-
=== June 28, 2011 ===
+
-
 
+
-
* svn offline this weekend to migrate servers (Huy)
+
-
** send an email to vistrails-dev
+
-
* fix bugs from demo
+
-
** fix zoom on open, change view
+
-
** detach configuration window, rename, in a read-only, non-changing state (allow copy)
+
-
** read-only controller for diff view, or use Emanuele's read-only view flag
+
-
** check for pruned versions in "(latest)" version
+
-
** failed to index error on open (possibly old version of vistrail--with filenames)
+
-
 
+
-
* releases?
+
-
** waiting for ALPS build for Mac OS X 10.5
+
-
** allow 2.0 vt files to open in 1.7 (e.g. those with mashups)
+
-
 
+
-
=== June 21, 2011 ===
+
-
 
+
-
* Querying
+
-
** need ability to better navigate results
+
-
** show query results in side panel?
+
-
** search all open vistrails (change label on the search)
+
-
 
+
-
* Updated workspace window
+
-
** Separate open and recent files
+
-
** Delete closes an open vistrail or removes a closed one from recent file list
+
-
** Also has an "open in new open window" option for right-click, suggested "open in new window", "open in new tab" for workflows
+
-
** Want to be able to show this palette at all times?  This allows better navigation, but problem is the screen space
+
-
** Try showing the workspace window in the upper left and "normal" left palettes in the lower-left.
+
-
 
+
-
* Module Palette
+
-
** Searching should expand things automatically, especially for searches that have only a few search results
+
-
** What about searching a particular package? Could auto-expand on begin search, user collapses and then expands the package they are intereseted in
+
-
 
+
-
* Global variables
+
-
** one bug on disconnecting variables
+
-
 
+
-
* Spreadsheet and analogy issue on re-executing pipelines? Dave will look at
+
-
 
+
-
* Diff
+
-
** Diff properties not showing up automatically, Emanuele will check
+
-
** Implement a diff in workspace window so you can do cross-vistrail diff
+
-
** Diff uses version tree for efficiency, but we can use analogy match or heuristic even when no actions are shared
+
-
 
+
-
* Inspector window: would be nice to keep this window smaller (certain tabs keep it large)
+
-
 
+
-
=== June 14, 2011 ===
+
-
 
+
-
* Detach windows
+
-
** notifications?
+
-
** creating secondary windows
+
-
** don't duplicate the entire vistrails window, just individual views
+
-
** detach icon not displaying correctly in Windows
+
-
 
+
-
* Global Variables
+
-
** How to add to modules?
+
-
** Drag constant modules to the vistrails variables panel
+
-
** Set the value by editing the constant in the vistrals variables panel
+
-
** Connect the value by dragging the constant from the vistrails variables panel to a port in the pipeline
+
-
** Update default text to "Drag constants from Modules panel to create variables"
+
-
** Fix bugs with connecting globals and deleting them (versionTab issue, etc.)
+
-
 
+
-
* Query tab in vistrail
+
-
** Can we use normal version/pipeline views as result views?
+
-
*** Which view to start with? history/pipeline
+
-
*** Show the workspace panel instead of history view
+
-
*** Show results in the query panel (as pipeline or workspace as appropriate)
+
-
** Should we always combine "keyword" and "visual" queries?
+
-
*** try to combine queries when possible, but allow user to search just text if there is no pipeline or just pipeline if there is no text
+
-
*** get back to the search window after seeing results (need a button here)
+
-
** What interactivity do we want? Open pipeline when matching version is double-clicked?
+
-
*** yes, single-click shows in results view, double-click opens as normal vistrail
+
-
** Dave will look at query view
+
-
 
+
-
* Add read-only PythonSource
+
-
 
+
-
* Workspace: keep closed vistrails here too
+
-
** try to order so that open vistrails are on top (highlighted in bold?)
+
-
** also show different views here (full tree view)
+
-
** show current workflow (ie latest version in the panel), too
+
-
 
+

+
-
** how does execute work
+
-
** close builder window doesn't trigger quit?
+
-
 
+
-
* Provenance view [Tommy]
+
-
** read all provenance right now
+
-
** create an index file in the vt to load pieces of provenance on demand
+
-

+
-
** tooltips in the browser view show large icons
+
-
** search for provenance browser
+
-
** fix issues with the left box
+
-
** number of search boxes...
+
-
 
+
-
* Update splash screen [Juliana will talk to Nathan]
+
-
 
+
-
* Go over Jan's feedback on the PythonSource editor
+
-
 
+
-
''A slight UI glitch is that I couldn't access the undo/redo functionality with the usual Cmd+[Shift+]Z shortcuts (neither via the menu or toolbars) but only via the right mouse button. One additional feature that might be nice in the future would be some minimal indentation assistance, like when pressing [Return] the current indentation is kept for the new line.''

===Mar 22, 2011===
+
-
 
+
-
* support a subset of VisMashup within VisTrails: re-use subworkflow infrastructure, and add the functions which create the application. Similar to subworkflows, mashups could live inside a vistrail
+
-
** [DK] Note that mashups are higher-level objects than workflows.  It would seem that mashups should include vistrails.
+
-
** [JF] My idea is really simple: when we create a subworkflow we are essentially creating a 'view' that hides away the details of the underlying modules and only exposes a subset of the parameters. What I would like to have is the component of VisMashup that takes a subworkflow specification and generates the app.  This would greatly simplify the publication of *interactive* results. And I believe, it would be simple to implement since it would re-use the existing infrastructure we have for subworkflows.
+
-
 
+
-
* support for global variables: maybe, an initial approach could be to have such variables associated with a vistrail. This would greatly simplify packaging of workflows, in particular, to deal with file locations in different systems
+
-
** [DK] We have discussed this before as having '''workflow'''-global parameters and have proposed a method for accomplishing this---namely modify the interface to hide global parameters.  It may be possible to have them for entire vistrails, but note that this poses problems. Suppose a user that creates a workflow identifying 'x' (a Float) as a global variable, and then changes the workflow and identifies a new parameter as 'x' but its type is now a String.  A per-workflow definition of the global 'x' is fine, but a per-vistrail definition is not.  I agree that we should try to support some style of alias-like behavior so that a user can set parameters more globally, but it is important that these settings are saved as provenance as many of these might be per-session...
+
-
** [JF] I want global variables to simplify packaging of results. Having them on a per workflow basis would not solve the problem I had: In the WikiQuery case study I have a series of related workflows that all rely on the same set of input files; so in this case, I would need global variables at the VisTrails level.
+
-
** [JF] As for the issue DK raised, I think we could have a very simple solution: we check for conflicts with global variables and prevent the used from making mistakes
+
-
 
+
-
* SubWorkflows in the database (Tommy)
+
-
** abstractions==subworkflows? Some error messages still refer to abstractions
+
-
** Logic for merging subworkflows from different sources? (Upgrading issues?)
+
-
* Control Flow Assistant feedback (Tommy)
+
-
* From Matthias:
+
-
** Remote execution: make it easier to move executions to clusters, starting them from VisTrails, waiting for the results.  Can we make Joel's code for the wildfire simulations more flexible?
+
-
** Using VisTrails for validation: make it possible to take results of a workflow, and compare them with a previous result to validate that changes in code or VisTrails have not affected the results.
+
-
** Make it easier to select a persistent repository (test, release, etc.) so that the same workflow can be run against different repositories
+
-
** Better support for querying hundreds of data files (ie create a database of metadata that a user can use to filter the set of files to locate specific files quickly)
+
-
** Along with this, allow this to work over existing (non-persistent) repositories.
+
-
** A better python editor for PythonSource

'''Items to Discuss'''
 +
* [TE] Backporting features from Python 3 + PyQt5 + Qt5
 +
** Merged unicode with master ([https://github.com/VisTrails/VisTrails/tree/unicode unicode])
 +
*** One unicode test failing
 +
*** Problem saving to xml
 +
** Used [http://python-future.org/ python-future] to run futurize stage 1 to update legacy (pre 2.6) code ([https://github.com/VisTrails/VisTrails/tree/unicode-futurized unicode-futurized])
 +
*** Updates print to functions 'from __future__ import print_function'
 +
*** Updates exception calls to use 'as'
 +
*** removes most usages of 'long' (mostly used unnecessarily)
 +
**** Only needed for 32-bit support
 +
*** Fixes relative imports (from __future__ import absolute_import)
 +
** Fixing code that is deprecated in Qt 4.8 and removed in Qt 5 ([https://github.com/VisTrails/VisTrails/tree/unicode-futurized-qt5 unicode-futurized-qt5])
 +
*** 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.* [https://github.com/VisTrails/VisTrails/pull/1002 #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

** Successfully built [https://gist.github.com/rexissimus/f1a1aada7de1c00a57c7 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 [https://python3wos.appspot.com/ 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

-
** Errors with old versions of pipelines, need to fix pipelines
+
-
** console_mode_test can't be enabled
+
-
 
+
-
* Data publishing with CrowdLabs
+
-
** using persistent files and directories?
+
-
** couldn't think about how to synch user directories with server directories
+
-
** look into how to push data files across with git
+
-
** how to organize data (ie persistent files) from a specific workflow or all workflows with specific parameters
+

-
* [DR] Subworkflow upgrades: update--is it a wrap?
+
-
** functionality are completed
+
-
** one cosmetic issue -- disabling a package
+
-
** subworkflows move from top to bottom of the list
+
-
** [DR] Add documentation to wiki on subworkflow upgrade paths
+
-
 
+
-
* [DR] control flow assistant
+
-
** started looking into this
+
-
 
+
-
* [TE] [[Data/provenance browser]]: update
+
-
** looking at the old code
+
-
** some problems with the logs
+
-
** cannot find parent workflow
+
-
** adding project annotations to sort VisTrails into different projects, different vistrails in different project, need to have gui to do this
+
-
** synchronize when vistrail changes, especially with execution logs, create index schema for these files (vistrail and workflow exec)
+
-
** persistent data index, need to integrate eventually, scan through actions to generate list of files used
+
-
 
+
-
* PythonSource editor
+
-
** seeing which PythonSource editor is open
+
-
** need to be able to have "save now" button or automatically save when someone presses "execute"
+
-
** generate id tag automatically, close the other window immediately
+
-
** highlight module being edited/configured, keep window open (like console, messages)
+
-
 
+
-
* Lack of global variables and bookmarks
+
-
** don't need to reconfigure executions to do this
+
-
** just don't display the "global" modules and connections
+
-
 
+
-
* [CS] look into 3 items for [MT]'s group: ports display, python source, global vars and bookmarks (and persistent files dump)
+
-
 
+
-
* [PM] Merging master and crowdlabs git branches. How should we merge the crowdlabs branch into the master branch?
+
-
** problem is that there are changes in crowdlabs that can't go in the master branch (i.e. HTTPFile)
+
-
** [ES] just merge both so we don't have the crowdlabs branch
+
-
** [PM] change RepoSync to have a server config preference that is set to True for server, False for client, and RepoSync has an if in the compute that does one thing if server is true, another if server is false
+
-
** have a branch for workflow indexing so that patch lives in another place
+
-
 
+
-
* Box input ports should be colored (e.g. black) if they are already set by an internal method. Another color (e.g. red) could be used to indicate mandatory input ports.
+
-
** Currently, non-optional ports are square, shown. Optionals are circles and must be enabled
+
-
** Add a third category for mandatory, problem is backward compat.
+
-
** [ES] Colors are already overloaded, not for ports, use shading instead?
+
-
** Also needs to be with global settings, etc.
+
-
 
+
-
* 1.6 release: [ES] already has 1.6 candidate
+
-
** don't include the new gui features yet
+
-
** freeze 1.6, just bug fixes
+
-
** merge crowdlabs branch
+
-
 
+
-
* [DK] persistent files on the server
+
-
** [MT] has problems with files on server, issue with /tmp/, running older python (2.5)
+
-
** stress test, test on [DR]'s machine
+

-
 
+
-
* [DR] Subworkflow upgrades
+
-
** Made sure that we don't rewrite actions but create new actions that show where subworkflows are upgraded
+
-
** Document what is implemented and how it works (at high level), also what isn't yet implemented
+
-
 
+
-
* [TE] Errors and web services
+
-
** allow user to decide to only display errors to messages window instead of also showing popup windows
+
-
** Allow add/delete of web services from GUI without going to preferences
+
-
** Qt dependencies for error messages gone
+
-
 
+
-
* [PM] Some specific questions
+
-
** Question: Should v1_0_1 MySql schemas be upgraded to v1_0_2?
+
-
** db_connection.begin() being removed, stale results
+
-
** memory size is too big for the field size
+
-
** [DK] check on schema changes, see what is important for changes
+
-
 
+
-
* Question: do we display 'warnings' or only errors?
+
-
** Need to write ModuleErrors (maybe make ModuleWarnings) to the messages (debug) as well as adding as tool tips
+
-
 
+
-
* Some suggestions/requests by Matthias:
+
-
** Support the grouping of vistrails and files into projects
+
-
*** Annotation here?
+
-
** Ability to set global parameters/bookmarks=workflows (e.g., a filename or path)
+
-
** Archive results -- create a big tar/zip file with all vt and results
+
-
** Ability to add a vt: if a node is deleted, all data associated with that should also be deleted
+
-
** Create a test suite: run a workflow, save and archive results (user could specify which results should be saved)
+
-
 
+
-
* [[Data/provenance browser]]
+
-
** We need a better mechanism that allows users to search/query for workflows and provenance, for example search by project, parameter names and values
+
-
** One way to view this is to allow the creation of mappings between the vistrails/projects into different structures---like "smart folders", e.g., /projectN/vt1/wf3/exec23/O1....
+
-
** Support editing and synchronization in both ways (if edit smart folder, should update vt)
+
-
** Should be able to script the use of the browser, e.g., to test a new version of a workflow against a saved test suite
+
-
** Scientists like a directory structure and can go browse there like they browse files with finder/explorer
+
-
** Keep mappings from our datatypes to file structures
+
-
** Need an exportable archive (to send with a paper, allow browsing outside of VisTrails)
+
-
 
+
-
* On merging master and crowdlabs git branches
+
-
** some updates on the crowdlabs branch need to be merged/patched into the master branch
+
-
** how should this be done?
+
-
 
+
-
* PythonSource editor
+
-
** modal or multiple window editors?
+
-
 
+
-
* Lack of global variables and bookmarks
+
-
** Problem is that aliases don't change workflow specification
+
-
** Need to store these values in the execution log
+
-
** Keep alias dictionary for everything
+
-
** [PM] Not a need for global variables above the single workflow level
+
-
** This already exists at the conceptual level---one module with connections to other modules, this just is cluttered
+
-
 
+
-
* Unit tests

** [ES]: I ran the test suite on current master branch and 207 tests are executed of which 11 fail. Some of the tests are failing because console_mode_test package can be imported anymore (this is a package created specific to run console_mode tests).

* Data publishing with CrowdLabs
+
-
** Using git to manage data between local and server data stores might be too messy.
+
-
*** Does one create a new git repository for each vistrail on crowdlabs?
+
-
*** The local persistent git repo holds all persistent data used on that machine. How does one push/publish just one data product using git?
+
-
*** Can anybody think of a plausible git workflow to do this?
+
-
** Perhaps we should just look into adding directory support for RepoSync module along with a better data management UI.
+
-
** Are there OS independent file transfer protocols better than HTTP? Something like rsync might work nicely, but windows support is limited.

* Subworkflow Upgrades (Daniel)
+
-
** Should be completed finished tonight
+
-
** Local subworkflow upgrades should be working now
+
-
** Need to test these after the checkin
+
-
** Using a dummy controller
+
-
 
+
-
* Assistant for control package (Daniel)
+
-
** Look at examples
+
-
** Try to make an assistant to modify workflow using currently selected modules as looping group
+
-
 
+
-
* [[Improve error handling/reporting]]
+
-
** Tons of message boxes pop up when a workflow has a bunch of errors, UI response is bad after this...
+
-
** Update existing error messages
+
-
** Show Details rendering on Mac
+
-
** What to do when multiple errors occur in a single event?
+
-
** New dialog that shows "next message" but allows user to dismiss messages or view all in the messages window
+
-
** Color coding for messages: use gui/theme.py to configure: maybe try black for warning, gray for log level messages
+
-
 
+
-
* Data and workflow browser (Nivan will give a status update)
+
-
 
+
-
* Saving Explorations (Feature Request from ALPS)
+
-
** We already save parameter explorations with the workflow in the version tree. As is, we save only the last exploration that was done for a given workflow.  If you ship the vistrail, the saved parameter explorations will be there.  Is this sufficient?
+
-
** [MT] Yes, that takes us a long way. Could one add a button in the explorations to save a certain set of explorations as a new version, like you do with the camera angle in the spreadsheet? That way one could store more than one set of exploration parameters without forcing a new version to be created with every change?
+
-
** Eventually we should provide a selector in parameter exploration
+
-
** Fastest to just allow a null action new version (a bit clunky) but wouldn't require too many changes
+
-
 
+
-
* Clean up/prune persistent directory
+
-
** What are the concrete use cases for this?
+
-
** [MT] Here are two concrete use cases that appeared over the last week:
+
-
*** a project is done, the important results copied to an archive and I want to get rid of all its intermediate files, etc., to save space - but not those files associated with other projects. Or, similarly, I'm done testing some workflows, want to remove all (partially buggy or irrelevant) files, and then start with production runs.
+
-
*** there was a problem in a workflow(e.g. a bug in HTTPFile module with binary files or a bug in some user code). I want to force a certain persisted directory to be "forgotten", so that I can repair the wrong files. Bumping the version number of the ALPS package would be one way, but that is overkill since it would immediately invalidate all persisted files. Removing the whole persistence directory is just as radical.
+
-
** just testing simple tutorials with small files leaves me with 2 GB of persistent data after 10 days, in 142 persistent directories or files. I need some way to clean this up that is less radical then removing all persistent directories and files.  This could be done, by e.g. removing all those which do not occur in tagged or leaf workflows in a certain set of vistrails. Or marking those which occur in certain vistrails with certain labels, and then being able to prune all those with or without some label/tag. Another option might be having the ability to choose from various repositories.

+
-
** work in progress
+
-
 
+
-
* Data Publishing with crowdLabs. (Phillip) 
+
-
** Do we want data publishing capabilities in VisTrails and crowdLabs?  '''YES!!!'''
+
-
** If so...
+
-
*** Currently limited data provenance for data. HTTPFile module lacks meta data, RepoSync module has poor usability.
+
-
*** Persistent Data works for experimental data. Can we use it for publishing data?
+
-
**** Publishing data or storing data on the server and pushing back and forth?
+
-
**** What is the current scheme for identifying data on the server?
+
-
**** Do we need to do better than the ids, versions, hashes that the peristence package provides?
+
-
*** Do we want to utilize data publishing software like [http://thedata.org/home The Dataverse Network] or maybe [http://www.fedora-commons.org/ Fedora Commons]?
+
-
** [ES] Feature request: Can RepoSync support a directory of files?
+
-
*** [PM] It can't, and I'm not sure how add it. I also don't really like the current RepoSync interface. It's not obvious how your data is being handled, hence me bring up data publishing, so hopefully we can come up with something more usable/robust.
+
-
** persistence used more for exploratory
+
-
** want to focus on more archive
+
-
** move from exploratory data to published
+
-
** Dataverse: essentially a site to curate data, archive data, host their own site, each university has their own server, linked together
+
-
** persistent store integration: maybe use git to do this, can add to local repositories to move to git
+
-
** use some of the dataverse: standard hash schemes, etc.
+
-
** privacy: can users push workflows without exposing data
+
-
** permissions for who can check things out: download permissions, upload permissions
+
-
** look into setting up persistent store on
+

* DisplayWall (Wendel)
+
-
** new version of vistrails receives rotate/scale messages much more slowly
+
-
** using the vtk version that is already there
+
-
** comparing VisTrails 1.2 with nightly src
+
-
** test when the messages are received on the clients
+
-
** [ES] Changed something in the VTKCell, using the Qt interactor from vtk now, just uncomment this (vtkcell.py file)
+
-
** some commands are missed; check why this is happening
+
-
** preferences switch? 2x2 not 2x3
+
-
** check what modifications exist in the client code that's not exactly 1.2?
+
-
** new version of vtk package changed some things
+
-
** update vtk upgrade: resetcamera and addrgbpoint => _# versions
+
-
** Demos on displaywall: Wendel has to keep both VisTrails running and stop work when visitors stop by unannounced
+
-
 
+
-
* Relative paths in workflows, how to deal with them? (Emanuele)
+
-
** [ES] Updated all examples to use HTTPFile for these
+
-
** some of these had to change completely (color widget), kept tree the same format
+
-
 
+
-
=== Nov 16, 2010 ===
+
-
 
+
-
* Data and workflow browser (Nivan)
+
-
** Check into git branch (Dave)
+
-
** Add data support to the vistrails, workflows, and execs already exposed in the browser
+
-
** Add thumbnails to the browser
+
-
** Bittorrent support?
+
-
 
+
-
* Upgrade issues -- a wrap? (Daniel)
+
-
** Fixing some issues with namespaces
+
-
** Upgrades for subworkflows that are included with packages, need to save these upgrades with the vt file as a "local abstraction" to ensure provenance.  May be able to tie these back to the package versions once the package is upgraded.
+
-
 
+
-
* Test Suite
+
-
** Matthias has his own test suite now
+
-
** We should make sure that our tests are up-to-date and run them before releases
+
-
 
+
-
* Web services on users' guide (Tommy)
+
-
** Users' guide needs only a few changes.  One of the changes should be a note making it explicit that we are using a new library and the old one was deprecated.
+
-
** Do we want to update the 39-page guide as well?  For now, just update the users' guide.  Don't distribute this guide.  Just include it in a zip file that includes the old version.
+
-
 
+
-
* [[Improve error handling/reporting]] (Tommy)
+
-
** print statements, has a new window
+
-
** add a menu item to view message window and also keep all messages from the session
+
-
** look into writing QMessageBox errors and warning to message window
+
-
** write all messages to a single window, write critical messages in red?
+
-
** have a utility method that encapsulates the gui error display and the core.debug display (if not running gui, only write to core.debug)
+
-
** don't display stack trace in a qmessagebox?  -- try to emulate the invalid pipeline with "Show Details" button.
+
-
** make it easier for users to report errors by having a "copy" or "send to developers" button to report the details of an error.
+
-
 
+
-
* DisplayWall (Wendel)
+
-
** What examples should be in the SVN? If we decide to keep some examples in the svn, some of them use data that should be along.
+
-
*** Indicate progress of HTTPFile
+
-
*** Had to upgrade examples to work with new examples of VisTrails
+
-
*** VisTrails can send progress information with another thread like crowdlabs can do
+
-
*** Each machine has a .vistrails and needs to download own version of data, make a single .vistrails for all machines?
+
-
*** All slave machines can use the server as a cache?
+
-
** DisplayWall Client on the Apple Store? I dont like the idea of sharing the client source code. And putting the app without login/password will allow anyone to access our displaywall.
+
-
*** Add a password for this
+
-
*** Do user management?
+
-
 
+
-
* VTK package:
+
-
** Have two ResetCamera modules now
+
-
** Need to write upgrade code
+
-
** Only with vtk 5.7 right now
+
-
** Encode library version in the package version?
+
-
** For reproducibility, we probably want to stick to specific versions
+
-
** We still need some ability to run new versions of vtk for testing, new features, etc., too...
+
-
 
+
-
* Relative paths in workflows, how to deal with them? (Emanuele)
+
-
** Should we use dataDirectory?
+
-
** Change examples to not use hard-coded files?
+
-
** Problem with workflows, not data files
+
-
** On Windows, use ../examples
+
-
** On Mac, use ../../../examples
+
-
** dataDirectory not used, I think
+
-
** create "$VT_EXAMPLES"?
+
-
** problem is using new versions of VisTrails, data may change so referencing old location will fail
+
-
** don't allow users to change this variable
+
-
** convert to use HTTPFile
+
-
 
+
-
* Data files and the GIT Repository (Emanuele)
+
-
** make a separate repository or use the submodule git functionality
+
-
** go with submodule
+
-
 
+
-
* Next release: What still needs to be done?
+
-
** high priority from ALPS list
+
-
** Dan's fixes to the upgrade workflow
+
-
** Date for release?  Official release in beginning of December for ALPS
+
-
** All developers should run test suite on push
+
-
** Could make this somewhat automatic, run with nightly release script and email -dev list
+
-
** Could have different classes of tests, make sure that critical ones pass
+
-
** Tests have a bunch of errors currently
+
-
 
+
-
* Saving explorations:
+
-
** Keeps track of the latest exploration for each version
+
-
** Check with Matthias what the requirements for this are
+
-
** Have way to send just specification to a server (run this workflow with this parameter exploration)?
+
-
** Can we have an xml spec that specifies the parameter exploration (export parameter exploration)
+
-
** Currently persisting via xml and then converting to string so we already have an xml serialization
+
-
** Dan wrote API that takes xml string and populates the param_exp gui with the appropriate values
+
-
** Need to back the GUI state with core state to enable short-circuiting the gui
+
-
 
+
-
 
+
-
* Box input ports should be colored (e.g. black) if they are already set by an internal method. Another color (e.g. red) could be used to indicate mandatory input ports.
+
-
** Currently, non-optional ports are square, shown.  Optionals are circles and must be enabled
+
-
** Add a third category for mandatory, problem is backward compat.
+
-
** [ES] Colors are already overloaded, not for ports, use shading instead?

+
-
* FAQ
+
-
** As we reply to users queries, let's add the question and answer to the FAQ!
+
-
** Just a reminder
+
-
 
+
-
* Caching of File module
+
-
** There was a message from a user who got confused because this module is cached by default (and silently). And in his application, since the file actually changed in between runs, he did not see the 'expected' result.
+
-
** Should we keep a hash for files and check whether they changed?
+
-
** Should we no cache File by default?
+
-
** [DK] File is supposed to have a special signature computation that detects changes in the file contents so this may be a bug instead.  It does work, it seems to be an issue with the create_file
+
-
** [ES] In this particular case, the file was empty. He deleted the file outside VisTrails and executed it again. As he set create_file to True, he was expecting the file to be created again.
+
-
** [DK] Add random salt to hash signature when the file doesn't exist and create_file is True
+
-
** [JF: DONE] Juliana will edit the FAQ to note that the signatures are dependent on modification times
+
-
 
+
-
* Claurissa will demo different ways to visualize the version tree
+
-
** weighting on various criteria for displaying nodes (importance from session, user, tags, etc.)
+
-
** other modes for viewing the versions (lists or timelines)
+
-
** often see only linear trees, teaching or thinking other than tree?
+
-
 
+
-
 
+
-
 
+
-
* Upgrade issues (Dan)
+
-
** Vanilla upgrades should be in today's commit
+
-
** Added code so when doing upgrade to check whether the latest code is upgraded
+
-
** Two types of upgrades: (1) User changes the subworkflow, (2) Modules are out-of-date and need to be upgraded.
+
-
** Add higher-level features like "Upgrade All" for (1), "Import Changes to My Subworkflows", etc.
+
-
** Want a 1-1 mapping between unique subworkflow id and a subworkflow file (even if we copy the same subworkflow to different vistrails)
+
-
 
+
-
* Offscreen bug  (update from Huy)
+
-
** Mac issue when switching to Cocoa
+
-
** Huy added a QWidget for each of the render windows that is created, so should be fixed.
+
-
 
+
-
* Gesture support
+
-
** Someone on Windows check the pinch gesture support; it doesn't work for Matthias under Parallels
+
-
** VTKCell is working now
+
-
** Cell dependent, panning now maps to middle button, pinch on the base widget
+
-
** What are Matthias's requirements here?  Does touch gestures in the cells matter or only in the vt/wf views
+
-
 
+
-
* Thumbnails: [JF: this needs to go to trac, for 2.0?] [ES: 2 tickets were created for 2.0]
+
-
** Resolution? -- [ES] problem is the size of the vistrail, but this can be configured
+
-
** Can we export to PDF instead of PNG? [ES] cannot display the thumbnail as a PDF in Qt?
+
-
** Can we have the option to save higher-res or PDF versions of the thumbnails
+
-
** Can we have preferences that allow users to save a higher-res or PDF version, maybe a checkbox
+
-
** Maybe associate a high-res version with a spreadsheet cell so that we can save a high-res version on demand
+
-
** high-res version associated with a version but allow user to initiate action from spreadsheet
+
-
** can we have thumbnails dependent on camera position [ES] doesn't like, user won't see exactly that image upon re-executing
+
-
** compact vistrail option by removing thumbnails
+
-
 
+
-
* Tommy has rewritten the Web services module as well as updated all of the examples
+
-
** Server for one of the examples seems to be down
+
-
** Need to update the manual
+
-
 
+
-
* [[Improve error handling/reporting]] (Tommy)
+
-
** Maybe display the intialization messages with the splash screen?
+
-
** Debugging levels have no way to access debug level
+
-
** Tommy takes first cut at trying to determine how to map print statements, notes those he is unsure of
+
-
** Developer guidelines for debug usage, use them instead of print statements in the futur
+
-
 
+
-
* Merge functionality (Tommy) [JF: Cool!]
+
-
** Can now merge an existing vistrail into your own vistrail using menu item
+

* Upgrading subworkflows (Dan)
+
-
** add updated versions to subworkflow vistrail and push to registry
+
-
** fixed bug with version/descriptor redirects
+
-
** key remaining task is to replace the box representing the subworkflow in the top-level workflow to reflect the change to the upgraded version of the subworkflow
+
-
** many corner cases, but we should get the vanilla upgrade (working) to git
+
-
** need to ensure that each subworkflow file has its own uuid; if a subworkflow exists in two different vistrails, it should have a different uuid (namespace).
+
-
** otherwise, we can get crosstalk where one vt can update the subworkflow from another vt (we can propgate changes to other vts via merges, but this should be a user choice...)
+
-
** enhancements:
+
-
*** allow users to merge subworkflows from a file into their own subworkflow (to incorporate outside changes)
+
-
*** latest version is the most recent non-upgraded version; if that version has an upgrade, use the upgrade
+
-
***'''Next step: work on usability for controlflow package; explore Dave's idea of an assistant'''
+
-
 
+
-
* Offscreen bug
+
-
** Huy is looking into this
+
-
 
+
-
* Crash due to issues in loaded user packages (Tommy has fixed this)
+
-
 
+
-
* Web services (Tommy)
+
-
** Package is completed, and all but one of our examples are working
+
-
** '''Tommy will test if the Web services will work when there is a proxy'''
+
-
 
+
-
* Improve error handling/reporting (Tommy)
+
-
** we should have a single point for all error messages to pass through that is linked to both core.debug and GUI elements that display error messages.
+
-
** the goal is to implement a function that will be the single point for error messages, and that work without emitting GUI signals in core. As Huy suggested, we should have a GUI-wrapper which will be a no-op when the GUI is not instantiated---this will get rid of some of the pyqt dependencies (at least for the error messages).
+
-
 
+
-
* Improvements to VisTrails server communication with clients to better handle errors/crashes (Phillip)
+
-
** Currently the VisTrails servers consists of: a single-threaded instance with GUI; multiple GUI-less threads
+
-
** We will extend the server API to allow clients to check the server status. The server will provide a separate socket and the client will be able to 'ping' the server; if the server is working properly, it will respond; if it does not respond, the client will have a time out
+
-
** The API will also support the ability to kill both the GUI-less threads and the single-threaded GUI instance. We can then restart the server components using Emanuele's new script.
+
-
** We should also allow users to set a per-workflow time-out; if the workflow execution takes longer than the pre-defined threshold, VisTrails will abort the execution
+
-
 
+
-
 
+
-
* Update on fixing VTK Package (Wendel)
+
-
 
+
-
** It seems that the ParaView package has the same issues.
+
-
** '''Wendel has already checked in the new wrapper into the trunk; Emanuele will test it'''
+
-
 
+
-
* Synchronizing VisTrails and ALPS releases (Emanuele)
+
-
** VisTrails latex package was extended so that python is no longer required. If python is not present in the system, instead of issuing a request to execute the workflow and retrieve the image from the Web, a local, previously saved image will be used.  It is now also possible to embed the images of workflows into the latex file. Documentation about these and other features are currently in the README file and examples (example.tex) provided with the latex package.
+
-
** Windows and Mac beta binaries already include ALPS
+
-
** Are we distributing ALPS as part of VisTrails then?  This seems backwards.  ALPS should VisTrails as part of their stuff, no?
+
-
*** '''We will have separate binary distributions: one with and one without ALPS'''
+
-
 
+
-
* Is a multi-touch interface to VisTrails possible now that it's supported by Qt? (Phillip)
+
-
** Yes, Qt 4.6+ supports multi-tocuh --- '''Huy will look into this; the goal is to make this work both for the workflow builder/tree view and the spreadsheet'''
+
-
** We still need to figure out what makes sense for multi-touch, however, do we have requirements from ETH-Zurich?
+
-
*** We want to map the zoom, pan, click, etc to multi-touch, so that VisTrails can be intractable on a multi-touch screen without a mouse
+
-
 
+
-
* What is the status of the Vismashup i{Phone|Pad|Touch} app? (Phillip)
+
-
** If you mean mac binary, there's an alpha version here: http://www.sci.utah.edu/~emanuele/files/vismashup
+
-
** Do you mean iphone app? [Phillip: yes]
+
-
** '''Wendel will look into this'''
+
-
*** One of the issues is how to effectively handle images that are larger than the memory on the iPods and iPads---we need to process these on the server or use a model that allows the image to be manipulated on the client
+
-
*** We also need to connect the app with the crowdlabs server, so that the app can get the list of mashups
+
-
*** Phillip will investigate the feasibility of working directly with JavaScript and bypass flash

* Update on Trac and Roadmap (Emanuele and David)
+
-
** Trac is now linked to git repository
+
-
** Roadmap on Trac has been cleaned up so we can hide completed milestones
+
-
** Tickets are being reassigned/revisited. Many tickets (24) are not associated with a milestone yet https://vistrails.sci.utah.edu/report/3
+
-
* Synchronizing VisTrails and ALPS releases
+
-
* Web services support (Tommy)
+
-
** discuss the interaction between the Web Services package and upgrades
+
-
* Subworkflows update (Daniel)
+
-
* Testing of new module drawing (Erik)
+
-
* Aliases
+
-
** Currently, an alias is stored on a parameter.  We need aliases to be stored at a higher level so that changing an alias is not a change to a parameter.  The one issue is that there is a link between parmaeters and aliases in that an alias can only exist for versions that have the specified parameter.  We might also have two versions where the alias points to different parameters.  We could just store aliases as a root-level workflow element so that the set of aliases is versioned corrected.
+
-
** In the current implementation, the aliases parsed from the parameters are stored in a dictionary in the workflow, so storing aliases as a root-level workflows element might be the way to go --[[User:Emanuele|Emanuele]] 19:50, 15 October 2010 (MDT)
+
-
* Error logging
+
-
** Suggest that we have a single point for all error messages to pass through that is linked to both core.debug and GUI elements that display error messages.  This should improve our error handling significantly
+
-
* PyQt dependencies in core
+
-
** Can we get rid of PyQt dependencies in core (and db)?  This would probably require moving the signals/slots that we currently use to a similar Python implementation which shouldn't be too difficult.  This would also require the specification of configuration widgets not as classes but rather some text that can be used to import the GUI elements only when using the GUI code.  However, what would happen with workflows that run in command-line mode but require some graphical output?
+
-
* Ports
+
-
** One annoying part of the current VisTrails model is that users are not given any visual indication that a port value is already set by a function or vice versa by a connection.  In addition, we have no way to specify or enforce cardinality on ports at design time.  It seems like we could allow developers to specify when a port should not be connected to more than one value (via a function or a connection), and give some visual feedback when a port has already been specified in one manner.

==== Meeting Notes ====
+

+
-
* Bug regarding userpackages at initial vistrails startup causing startup to fail.
+
-
** Still an issue, ticket still open as a 1.6 milestone
+
-
* Copy-paste bug

-
** Shortcut not working on Mac.  Focus makes shortcut try to copy pipeline.

* Synchronizing ALPS and VisTrails releases
+
-
** 1.6 scheduled for Dec. 1
+
-
* Webservices
+
-
** New library being used, but it's very low level.
+
-
** Simple types may cause problems with some web-services using complex or XML-based types.
+
-
** Need to make sure that this library can handle at least MOST of the web-services out there.
+
-
* Sub-workflows
+
-
** Daniel's changes seem functional and very slick.
+
-
** A little more work on it seems necessary.
+
-
** Need some easy GUI mechanism to delete a subworkflow.
+
-
** Is the exclamation point in the module draw the best way to handle this?  Make a tool-tip to explain it.
+
-
* VTK Wrapping
+
-
** Changes to VTK Python wrapping is causing headaches - particularly in backwards compatibility.
+
-
** Method typing has changed to expect things like "List" or "Vector" - makes things hard on the user when defining these inputs.
+
-
** Removing List and Vector types and replacing them with dynamically generated versions from Tuples.
+
-
* Aliases - Agenda pushed until after Vis.
+
-
* Error Logging - Unify some error handling to improve how exceptions are dealt with.  More on this after Vis.
+
-
* Refactoring out PyQt dependencies from Core/Db/etc - Need to move all the signals/slots into GUI elements.  Questions come when a workflow uses GUI elements as inputs.  - More after vis.
+
-
* Ports - We need a way of showing how a port is specified - function vs. input port.  Cardinality must be established in these cases.  Ordering on multiple connections should be handled in some way - whether it's just a documentation issue or a more fundamental one.
+
-
** Should we have a tutorial mode that bring up tooltips when someone does something new as if it were a live tutorial.
+
-
 
+

=== Oct 12, 2010 ===
+
-
 
+
-
* Trac and Roadmap (Emanuele): Emanuele suggested we should create a development roadmap and make it a permanent item on the agenda. The idea is to go through the Trac tickets and use them to build the roadmap that would be made ''public''.
+
-
** go through trac and sort by priority
+
-
** add other suggestions to roadmap as well
+
-
** admins can add milestones via the admin tab
+
-
** ''David will assign tasks on list; those assigned need to follow up and check and fix them''
+
-
 
+
-
* Update on [[PythonSource error reporting and logging]] (Tommy)
+
-
** ''Need to make sure that all messages are printed through debug.X, so that the debug level (verboseness in preferences) is correctly used''
+
-
** Can cut/copy/paste now
+
-
** Can we prevent the delete from happening?
+
-
** Phillip noted the spyder project has an interactive python console: http://packages.python.org/spyder/
+
-
** Can press enter to get to the end
+
-
** Need to check if this works or if we need to change
+
-
** Now have ability to see stack trace from the GUI (triangle menu)
+
-
** ''Suggest using a dialog to display trace when this item is selected instead of printing to console''
+
-
** Also saving stack trace to the execution log
+
-
** Also printing debug information to vistrails log
+
-
** ''Add trac item to fix prints to use debug''
+
-
** ''Try to fix core.debug to have gui.debug to eliminate Qt dependency''
+
-
 
+
-
* Update on subworkflow (Daniel)
+
-
** Notification when subworkflow is outdated triggered
+
-
** new_abstraction signal from registry in addition to new_module signal so that we can check if we need subworkflows to update
+
-
** How to display the possible upgrades (can be upgraded, can be upgraded but may break, etc.)
+
-
 
+
-
* New utility added by Carlos (currently at scripts/module_appearance) to draw fringes visually, which generates output that can be pasted directly into the add_module call.
+
-
** ''Erik will test this on Mac and Windows.''
+
-
 
+
-
* Preparing a "Get Started" tutorial for SIGMOD repeatability
+
-
** Do we have instructions on how to use the latex package without crowdlabs?
+
-
*** links to actual workflows in latex
+
-
*** have README and example for latex in the source
+
-
** Metadata associated with VisTrails: should we have the ability to add vistrail-level metadata? e.g., who created the vistrail, its purpose, etc.
+
-
*** have pointers to paper to workflow and vistrails
+
-
*** add pointers to papers
+
-
*** allow access to add/edit annotations at the vistrail level
+
-
*** ''add GUI element to allow people to edit/add annotations''
+
-
 
+
-
* Maintaining VTK package
+
-
** have four classes that don't wrap, have error even in python level
+
-
** works well with VisTrails otherwise
+
-
** haven't checked the new changes from the wrapping
+
-
** ''Wendel will check on the new version''

-
* Welcome Tommy!
+
-
 
+
-
* Update on subworkflow (Daniel)
+
-
 
+
-
* Issues raised by Matthias:
+
-
 
+
-
- need to automatically upgrade subworkflows. Currently it is necessary to manually upgrade a subworkflow whenever the version of one of the modules inside them changes.
+
-
 
+
-
- explorations do not detect an MplFigureCell embedded in a subworkflow.

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?

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

January 25, 2017

Updates


Items to Discuss

  • Scaling VisTrails
  • sql-alchemy, uuid, bundle branches/merges

January 11, 2017

Updates

  • [RR] New VisTrails version in Debian [1]

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?)

2016

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?)

September 14, 2016

Updates

Items to Discuss

August 31, 2016

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
    • Websites
  • [RR] users' guide on readthedocs: doesn't seem like we can have both the internal docs (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

Updates

  • [TE] Wrap-up notes

August 10, 2016

Updates

Items to Discuss

  • [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 example
      • Sometimes connections are wrong, executing workflow sometimes works, otherwise copy/pasting is necessary
        • Could be a bug in the old vistrail, but not sure
  • [DK] Subworkflows and uuids

August 3, 2016

Updates


Items to Discuss

  • [TE] Wrapper patches now stored as 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)

July 27, 2016

Updates

  • [DK] DB bundle serialization implemented

Items to Discuss

   def vtkInstance():
       self.vtkInstance = self

July 20, 2016

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
      • 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
  • [vistrails-users] Read data from SQL example?

July 13, 2016

  • [TE] Using vistrails API in scripting example 1 (API with VTK) example 2 (DownloadFile only)
    • Call module in script using vistrails API
    • Can be used when no export method is defined.
  • [TE] Server news bug Critical?

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
    • Should work well for matplotlib
    • 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.

May 4, 2016

Updates

  • VisTrails 2.2.4 released

Items to Discuss

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?
  • [TE] New bugfix release
    • Finalize survey

April 20, 2016

Updates

  • Merged upgrade fixes
    • Now has infinite loop test
    • loop test now correctly loops 5 times

Updates

Items to Discuss

  • [TE] Chaining upgrades done (#1164)
    • Replace "Upgrade" description annotation with "upgraded_from" annotation to identify which tags to hide?
  • [TE] Iterating handle_invalid_pipeline (#1165)
    • Not based on chain-upgrades-loop
    • Cherry-pick test to preserve source?
    • Need maxPipelineFixAttempts option?
      • The code is now smarter about recursion, so max attempts will "probably" never be reached.
    • Need debug messages?
      • Would need to be moved into handle_invalid_pipeline

April 6, 2016

Updates

  • [TE] Query View improvements
    • Done except for displaying "Version Info" and #1164
  • [RR] Working on finishing new interpreter (finally!)

Items to Discuss

Updates

Items to Discuss

  • [TE] Query View improvements
    • Unified do_version_switch and get_upgrades as validate_version()
    • Problems with query view using its own controller

Updates

Items to Discuss

  • [RR] Usage reporting almost ready to go
    • Need to record whether specific features are used: paramexpore, mashup, query
      • [DK] Record if LaTeX extension is used? But hard to distinguish from direct batch invocation
    • How to record size of vistrail?
      • [DK] IdScope already walks over vistrail, use that
      • but total number of modules and versions doesn't give an idea of average size of individual pipelines

March 16, 2016

Updates

Items to Discuss

  • [TE] Upgrades in Query Mode
    • Now using code similar to do_version_switch

  • [TE] Fixing search mode
    • String query now matches all by default
      • This caused pipeline queries to never match

      • Fixed notes search
    • '>' parameter queries in documentation but has been removed
    • Fixed module matches for upgraded pipelines (By not upgrading pipeline)
      • Upgrades still a problem

Items to Discuss

  • VisTrails Next
    • All tests but thumbnail comparison passes
    • Still issues with gui and more packages needs to be tested
    • PythonSource and MplSource upgraded with lib2to3
    • Keep contrib packages? Update?
    • VTK 7 is released
      • Supports Python 3
      • Will hopefully get into conda and others soon
      • Deprecates a bunch of modules

        • apt packages
        • conda packages
        • python packages in requirements.txt
        • python packages in setup.py
      • Can probably drop conda. Default builder does not have Qt5, but beta builder do!
      • But useful if we want to use conda in our own build process.
    • Lots of errors I do not get locally?
  • User Survey
    • Have you used any alternatives to vistrails?
      • Relevant? More options?
    • How often do you use any of these particular features in VisTrails?
      • Add/Remove alternatives?
    • How important would you rank the following potential improvements to VisTrails?
      • Add alternatives?

January 27, 2016

Items to Discuss

  • User Survey
  • ZMQ failing on windows (vistrails-users)
  • [TE] Python 3 branch
    • Testsuite almost passes
      • Failing are unicode filenames, some users guide examples, and thumbnail comparisons.
    • Fixed issues
      • Signatures are now bytes (convert to string to show in widget)
      • Cannot compare different types, e.g., (None < 1)
        • PortSpec.depth and min/maxConn could be None. (Backport!)
        • cell.row could be None
      • Lots of unicode/bytes fixes to serializations
        • We have encryption implementations in the code! (keychain)
      • Lots of small fixes to package method differences
    • Current issues
      • logging widget empty?
      • version tree signals messed up
      • provenance view legend icons black
      • Text do not fit in some widgets
      • VTK thumbnail comparison fails
        • VTK Cells have some faces in wrong direction?
        • Because running in VM?
    • Installing on Ubuntu LTS/Latest Mint
      • Install latest matplotlib from pip
      • Install VTK 7.0.0rc2 from source
      • No QtWebEngine binary (controversial) (Must install sip/PyQt5/Qt5 from source)

Updates

Items to Discuss

  • [TE] Backporting features from Python 3 + PyQt5 + Qt5
    • Merged unicode with master (unicode)
      • One unicode test failing
      • Problem saving to xml
    • Used python-future to run futurize stage 1 to update legacy (pre 2.6) code (unicode-futurized)
      • Updates print to functions 'from __future__ import print_function'
      • Updates exception calls to use 'as'
      • removes most usages of 'long' (mostly used unnecessarily)
        • Only needed for 32-bit support
      • Fixes relative imports (from __future__ import absolute_import)
    • Fixing code that is deprecated in Qt 4.8 and removed in Qt 5 (unicode-futurized-qt5)
      • 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

    • 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
