Developer meetings - MridulS/pysal GitHub Wiki

2015-09-11

  • Whole-library development conversations
    • Soft dependency structure and implementation
    • Relative tolerance levels for testing all over library
    • Who/When do we merge 2 to 3
    • Alternative release models (repurposing code freeze, rolling release + stable pegs)
  • Windows builds
  • 1.11 development priorities

2015-08-14(ish)

  • Blue Sky for next cycle:
    • Soft dependency structure
    • Weights from GeoJSON/GeoInterface
    • 2 to 3
    • others???
  • 2to3 port
    • tests pass in both now, but need to kick the tires
    • merge upstream when ready?
    • long-term development questions: develop in 2.7 always? or switch to 3 and port backwards?
    • Most people are writing python3-ready code anyway
  • Soft dependency
    • Would enable interop with Fiona, Statsmodels, Viz (seaborn + mpl + cartopy + ...), Pandas, patsy
    • Need to come up with structure for this (module like pysal.core.check?)
    • Core experience should be compatible with numpy-only systems.
    • (LJW) computations should take numpy, return numpy. Interfaces should take input and return same type in output (if possible)
  • Weights from GeoJSON/GeoInterface
    • like an extension of older pysal/shapely interface shim
    • gives us nice interplay with geopandas
  • Developer practices
    • projects in coming cycle should have one fork where the commits "live"
    • i.e. Serge working on wconstructor, makes a branch on his fork. All contributions go to his fork. He keeps it level with upstream/master and submits a PR when ready.
    • people need to git remote add more developers' forks to make this work

2015-05-01

  • network

    • might not use scipy sparsegraph (too many restrictions)
    • how to allocate attributes from polys to edges

  • 2-3 Port

    • looking for spreg testing of the 2-3 port
    • also need to do this in region
    • roughly an hour's work to do this for a module
    • convert int to float division
    • clone from lw 2-3 conversion branch
    • can install python-modernize via pip

  • weights abstraction

    • look into pyshp (geospatial python)
    • exploit geointerface
    • bind attributes to shapes and deal with id variables more cleanly
    • flyweight object using references to values rather than values in the json

1.10 priorities

Development organization

The leads above will push forward on the three threads. Anyone interested in working on one or more of those threads should ping the lead. We will also create a public branch for each thread and have a wiki page for each thread that documents progress. Leads will create the wiki page and branch for these three areas.
