Use 512-length filenames

[samsrabin]

Description of changes

Increases filename length in many places from 256 (CL) to 512 (CX). This was necessary to support a new test that ended up generating very long file paths (see ESCOMP/CTSM#3292).

I'm planning to merge in the latest CDEPS tag once I get an initial review.

Specific notes

Contributors other than yourself, if any: None

CDEPS Issues Fixed:

• Resolves aux_cdeps test for DATAMODELTEST compset fails #344

Are there dependencies on other component PRs (if so list): No

Are changes expected to change answers (bfb, different to roundoff, more substantial): bfb

Any User Interface Changes (namelist or namelist defaults changes): No

Testing performed (e.g. aux_cdeps, CESM prealpha, etc):

One CTSM test that was previously failing due to long file paths now passes.

aux_cdeps tests all pass except two that aren't the result of this work:

• SMS_D_Ld3.f10_f10_ais8gris4_mg37.DATAMODELTEST.derecho_gnu: fails because DATAMODELTEST isn't a valid compset name (This is issue aux_cdeps test for DATAMODELTEST compset fails #344)
• SMS_Ld3.f19_g17_rx1.2000_SATM_SLND_SICE_SOCN_DROF%NYF_SGLC_SWAV.derecho_intel: fails with "ERROR: no alias f19_g17_rx1 defined" (This is issue aux_cdeps test using f19_g17_rx1 fails, because no longer defined in ccs_config #345)

Hashes used for testing: 0595593

• Remove the DATAMODEL test from: dglc/cime_config/testdefs/testlist_dglc.xml
• Test after merging latest CDEPS tag

Looks good. This is nicely straightforward.

@jedwards4b and @billsacks this is ready to come in, after @samsrabin updates to the latest cdeps tag and redoes testing. Do you have any comments here? Or can he do that and then get this merged in afterwards? Let us know of changes you need, or other testing you'd like to have done.

Thanks

@samsrabin in light of the answer for #344, remove the DATAMODELTEST from:

dglc/cime_config/testdefs/testlist_dglc.xml

[samsrabin]

@ekluzek Removing that file would remove the failing SMS_Ld3.f19_g17_rx1.2000_SATM_SLND_SICE_SOCN_DROF%NYF_SGLC_SWAV.derecho_intel test, not the failing SMS_D_Ld3.f10_f10_ais8gris4_mg37.DATAMODELTEST.derecho_gnu that #344 is about.

[jedwards4b]

You just want to remove the DATAMODELTEST tests.

[ekluzek]

Yes, sorry I got it backwards.

Remove the DATAMODETEST from: dglc/cime_config/testdefs/testlist_dglc.xml

I've corrected it above.

[samsrabin]

@ekluzek Done!

[billsacks]

Thanks for this change - basically looks good. I see that you changed nlfilename and streamfilename for some data models but not others. Should this be consistent? See also the one inline comment below.

[samsrabin]

Good catches, @billsacks. Those are now addressed, and re-testing has aux_cdeps still passing (except the one remaining known-bad test).

[billsacks]

Looks good now - thanks for these changes that add more consistency!
