Eric, TomG, Greg, Zach

= Agenda =
* Action items
* ChimeraX
  - Programmer doc string formats and sphinx extensions #5120, Zach
  - Update 1.3 release roadmap, adding completed stuff, moving other stuff to 1.4.
  - Web service discontinued status checking for AlphaFold predict.
  - Task termination at app quit
  - VirtualGL documentation #4783
  - Rename ChimeraX.exe on Windows?
  - Should we remove the HTML tool tutorial and promote only Qt GUIs?
* Chimera

= Discussion =

* Versioning web services
  - ChimeraX and Chimera blast and modeler services may need to diverge when backend update is not compatible with old Chimera.
  - Modeller service has modelerV9 in name.
  - Eric will think more about how to handle web service backend versions.

* REST services and http vs https
  - REST web services currently all using http.
  - Eric suggests getting https working and keep http working as long as possible.
  - Our current web servers is apache
  - Discussed switching to nginx
  - Apache hard to configure https for multiple sites.

* Sphinx and doc strings
  - Zach suggests we use the Sphinx napolean extension included with Sphinx instead of numpydoc.
  - Napolean handles numpy and google doc string formats.
  - Zach will test it and show us good examples of how to format our doc strings.

* Python type hints
  - Discussed the advantages and disadvantages of Python type hints in function arguments and class attributes.
  - Eric points out ChimeraX plugin developers may find these hints confusing.
  - Greg points out speed optimizers for Python are trying to use type hints.  Guido has come out of retirement trying to increase CPython speed 2 fold.
  - Zach says type hints produce runtime error when wrong argument type passed that helps him debug code faster.
  - Zach suggests using a Sphinx extension so the type hints do not appear in function signatures in the documentation.
  - Decided that each developer can choose whether to use type hints.
  - Greg thinks might be possible that ChimeraX command registration could introspect function argument type hints instead of declaring the argument types in the registration call.

* Blast threading
  - Zach asks how to avoid blocking after BLAST rest returns results while code is fetching files containing results.  Can QThread be used?
  - Could use a Task.
  - Current blast gui in ChimeraX 1.2.5 blocks for 40 seconds on  4v6x chain A (900 hits) while loading results.
  - Suggest Zach complete new Qt blast gui before worrying about optimization.

* mmCIF saving error
  - Greg says user tried to save NMR ensemble where chain names were changed, gave traceback.
  - Will put in error checking.
  - mmCIF save tries to extract info from chimerax data structures that can be inconsistent and needs checking for compatibility with mmcif requirements.

* Roadmap for 1.3 release
  - Everyone update the 1.3 roadmap moving stuff that won't make it into 1.3 to the 1.4 milestone.

= Action Items =

* Put download web page checksums on separate page. Zach
* Propose registering only once at group meeting, see if TomF agrees - Everyone.
* Add 1.3 goals to roadmap for next group meeting - Everyone.
* ~~Get cron jobs to build mailing list site map for google indexing working  - Greg.
* Make Windows build redirect installer build to separate log so password not shown - Greg.
* ~~Make Updates tool started from menu Tools / Utilities / Updates show only updates, not all available bundles - Greg
* Change milestone on all 1.2 enhancement tickets that won't be in 1.2 to milestone 1.3 - Greg
* Check that all Toolshed bundles that install in 1.2 actually start -- add core<1.2 dependency to those that fail - Greg
