Some of the mysterious and undocumented tests in `mathics.tests.builtins.files_io.files` were commented out. TextRecognize tests were reinstated on Windows. We are getting mysterious Windows failures Python before 3.11, so we test on 3.11 alone for now. The doctest failures do not leave much of a trace as to what is wrong. Local testing on MS Windows also does not a trace either. As usual, this is probably not the final word on improving the behavior on MS Windows. However it is a start. --- .github/workflows/windows.yml | 8 +- Makefile | 12 +- mathics/core/definitions.py | 5 +- mathics/core/parser/convert.py | 11 +- mathics/core/streams.py | 3 +- mathics/core/util.py | 19 ++ mathics/eval/files_io/__init__.py | 2 +- mathics/eval/files_io/files.py | 13 +- mathics/settings.py | 4 +- test/builtin/files_io/test_files.py | 283 ++++++++++++++++++---------- test/builtin/test_evaluation.py | 25 ++- test/helper.py | 2 +- 12 files changed, 266 insertions(+), 121 deletions(-) diff --git a/.github/workflows/windows.yml b/.github/workflows/windows.yml index 0875de7f7..beae3c047 100755 --- a/.github/workflows/windows.yml +++ b/.github/workflows/windows.yml @@ -12,7 +12,9 @@ jobs: strategy: matrix: os: [windows] - python-version: ['3.10', '3.11'] + # "make doctest" on MS Windows fails without showing much of a + # trace of where things went wrong on Python before 3.11. + python-version: ['3.11'] steps: - uses: actions/checkout@v4 - name: Set up Python ${{ matrix.python-version }} @@ -46,8 +48,6 @@ jobs: run: | pip install pyocr # from full pip install -e .[dev] - set PYTEST_WORKERS="-n3" - # Until we can't figure out what's up with TextRecognize: make pytest gstest - make doctest o="--exclude TextRecognize" + make doctest # make check diff --git a/Makefile b/Makefile index 9b84d559e..57dc8c171 100644 --- a/Makefile +++ b/Makefile @@ -9,6 +9,7 @@ PYTHON ?= python3 PIP ?= pip3 BASH ?= bash RM ?= rm +PYTEST_OPTIONS ?= # Variable indicating Mathics3 Modules you have available on your system, in latex2doc option format MATHICS3_MODULE_OPTION ?= --load-module pymathics.graph,pymathics.natlang @@ -73,7 +74,7 @@ develop-full-cython: mathics/data/op-tables.json $(PIP) install -e .[dev,full,cython] -#: Make distirbution: wheels, eggs, tarball +#: Make distribution: wheels, eggs, tarball dist: ./admin-tools/make-dist.sh @@ -84,13 +85,16 @@ install: #: Run the most extensive set of tests check: pytest gstest doctest +#: Run the most extensive set of tests +check-for-Windows: pytest-for-windows gstest doctest + #: Build and check manifest of Builtins check-builtin-manifest: $(PYTHON) admin-tools/build_and_check_manifest.py #: Run pytest consistency and style checks check-consistency-and-style: - MATHICS_LINT=t $(PYTHON) -m pytest test/consistency-and-style + MATHICS_LINT=t $(PYTHON) -m pytest $(PYTEST_OPTIONS) test/consistency-and-style check-full: check-builtin-manifest check-builtin-manifest check @@ -113,9 +117,9 @@ clean: clean-cython clean-cache rm -f mathics/data/op-tables || true; \ rm -rf build || true -#: Run py.test tests.

From ffb3647d1659823a028fc160ed985bba0dcbc8d3 Mon Sep 17 00:00:00 2001 From: "R. Bernstein" Date: Tue, 12 Mar 2024 12:25:55 -0400 Subject: [PATCH 493/510] Modernize Python metadata (local) (#1014) Local fork of #1013 - Adds redoes packaging in the form that 3.12 is going to need since setuptools is deprecated. In the process, something happened with the way that Cython gets run and we were then getting lots of Cython type annotation mismatch failures. So these have been corrected. We could split this into just the Cython corrections and then apply the packaging toml changes in #1013.

For chapters, the change is quite straightforward. On the other hand, for sections, I think we need to think a little bit what is the best way to do this. One possibility would be to produce the documentation entry from the docstring of the target builtin, without passing through the documentation. The other way to go would be to keep a dictionary in the documentation, storing all the sections "by slug".
