Agenda Topics:

1. Open Pull Requests
2. Issue cleanup
3. Framework modifications:
   • Filter Infrastructure
   • Eliminating the mpas_constants module
   • Registry Validation
   • Critical error log files: "regularize" filenames, and add ability to print multiline messages
   • Integer overflow in ESMF time interval code
     • See branch https://github.com/mgduda/MPAS/tree/framework/esmf_i8_intervals
   • Fortran 2008 Support
4. Design Document Discussions
   • Pool Functions
   • Debugging streams
   • Arbitrary Attributes in Field Definitions
5. Testing infrastructure
   • Anything to talk about?
6. Long-term possibility for other I/O layers (e.g., netCDF4 directly instead of PIO)
   • See, e.g., https://github.com/mgduda/MPAS/tree/framework/nopio-clean/src/framework

Notes:

Discussion of design issues for block streams:

• Should block loop be pushed inside the mpas_stream_mgr_block_write routine? No, we may only want to write on block.
• Should the write routine verify that the filename template contains $B? There doesn't seem to be a clean way to handle this, so for now we don't enforce this.

May be possible to simplify new interval division code. Michael will try to find a version written last week. Test with ESMF_TimeMod.F90 from CIME for failures.

Fortran 2008: Doug has a branch with CONTIGUOUS keyword for MPAS-Ocean (?) core; someone else pick up this branch and extend to framework.

Registry validation can still be improved. Idea: split registry code into two stages that (1) validate the registry and (2) parse the registry to generate code.
