From 9c6848b6bf46e49185355f41928bb11cbb595a47 Mon Sep 17 00:00:00 2001 From: Dave Woodruff Date: Wed, 13 May 2026 15:23:14 -0700 Subject: [PATCH] misc cleanup: skip flaky test_values, fix dup-doc warning, ignore artifacts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three small loose ends bundled into one PR. * mpisppy/tests/test_admmWrapper.py, mpisppy/tests/test_stoch_admmWrapper.py: test_values in both files fails when run via pytest's subprocess capture (returncode=1, empty stdout AND stderr) but works identically when launched from a bare Python script or shell. The subprocess seems to die before producing any output — likely a pytest stdio-capture / file-descriptor interaction with Open MPI's I/O forwarding. Mark both tests with @unittest.skip and a clear reason pointing at the example bash scripts as the manual workaround until the root cause is diagnosed. * doc/src/generic_admm.rst: the file documents consensus_vars_creator twice (once for --admm, once for --stoch-admm), which produced a Sphinx "duplicate object description" warning. Add :no-index: to the --stoch-admm directive so only one ends up in the index. * .gitignore: add conservative patterns for mpi-sppy runtime artifacts that have been accumulating untracked in many users' working trees — per-rank iteration summaries, _delme*/delete_me* scratch dirs, specific.csv_* exports, example output files (ef.txt, hub.log, solution_*.txt, *_full_solution/, *_pickles/, *_cyl_nonants.npy). Leaves ambiguous patterns (e.g., archive/, CI/, *.perf.csv) untouched. Tests: 42 passed, 2 skipped (the two test_values). Doc build: 4 warnings -> 3 warnings (dup-description warning gone).
