OS X: "make ptestlong" with MAKE set leads to doctest failures in the doctest/ directory

[jhpalmieri]

Steps To Reproduce

With a number of homebrew packages in place, and with export MAKE="make -j8", run ./configure and make ptestlong.

Expected Behavior

All tests should pass.

Actual Behavior

I get doctest failures:

Additional Information

Note that ./sage -tp --long src/sage/doctest/ succeeds: I only see these tests when using make ptestlong, and I see them every time.

In addition, if MAKE and MAKEFLAGS are unset, then I do not see these failures with make ptestlong.

Environment

- **OS**: OS X 14.5
- **Sage Version**: 10.4.beta7 and many earlier versions

Checklist

• I have searched the existing issues for a bug report that matches the one I want to file, without success.
• I have read the documentation and troubleshoot guide

[mkoeppe]

Do the errors show up if you do make ptestlong-nodoc TEST_FILES=src/sage/doctest/control.py?

[jhpalmieri]

Do the errors show up if you do make ptestlong-nodoc TEST_FILES=src/sage/doctest/control.py?

No errors with this; I tried it two or three times and it worked every time. With make ptestlong-nodoc TEST_FILES=src/sage/doctest/, I see an error in control.py but not in forker.py.

Same thing happens on another machine.

[mkoeppe]

I can't seem to repro this on my machine. Could you post the config.log from the affected machines?

[jhpalmieri]

Let me revise that: when I run make ptestlong, I see

sage -t --long --warn-long 22.6 --random-seed=103198275017503752303450993870311094857 src/sage/doctest/forker.py  # 5 doctests failed

When I run make ptestlong-nodoc TEST_FILES=src/sage/doctest/, I see

sage -t --long --warn-long 23.4 --random-seed=279304829544013546166396286006292086053 src/sage/doctest/control.py  # 3 doctests failed

So I see failures, but fewer failures, in one file.

[jhpalmieri]

Here is one config.log file:

I get

so a slight improvement.

[jhpalmieri]

By the way, I think I have been seeing these failures for a long time, both on an Intel machine (which I no longer own) and Apple Silicon.

[mkoeppe]

I've found a few places more to change, please try #38122

[jhpalmieri]

For what it's worth, I did brew install make (which installs a newer version of make as gmake) and then export MAKE="gmake -j8", and I still get the same doctest failures with make ptestlong-nodoc TEST_FILES=src/sage/doctest/.

[mkoeppe]

Could you check if ./sage -pip uninstall gnumake_tokenpool makes a difference?
