Built w/o problems on three macOS platforms from a fresh clone of the develop tree.

10.11.6 (mid-2015 MBP, Quad-core Core i7): all tests passed!

10.13.6 (2017 iMac Pro, 18-core Xeon W): all tests passed!
However, repeating the “loop” testing of polynomials.pyx showed the same intermittent failures as before (this failure occurred in 4 of 8 tests).

10.14.2 (2017 MBP, Quad-core Core i7): one testing failure:
sage -t --long --warn-long 77.8 src/sage/numerical/backends/logging_backend.py # Killed due to abort

When run by itself the test passed. I then reran the full test cycle, with no failures (other than a batch of timeouts, due to my being unable to keep my MBP from going to sleep at intervals).

Log for the logging_bsckend failure attached.

Any ideas?

[Vincent Delecroix]

I can not reproduce the error. What is the configuration of
your machine?

The comparison routine in QQbar that is called
(cmp_elements_with_same_minpoly) assumes that the elements
a and b have the same minimal polynomial p. But the error message
is weird as it does not seem to be the case. The only roots of p
that looks like a and b are the following pair of conjugates

2.917983368234029?e15 - 1.630474617080222?e18*I
2.917983368234029?e15 + 1.630474617080222?e18*I

But the imaginary part is non-trivial! It seems that a and b
that appears in the error are here the *real part* of some roots
but not roots.

It would be helpful if you could provide more data (ie via pdb or
adding prints in qqbar.py). More precisely at lines 3367 (qqbar.py)
the values and types of
* sd._left._descr
* sd._right._descr
* sd._op
and also at lines 3372 the values of the polynomials
* lp
* rp

(the datatype of an element in QQbar is mostly a tree and
in the current situation sd._left and sd._right are the
two subtrees)

Ideally, it should be possible to reconstruct the element that
triggers the error... you can try to print a sage_input(self)
in the __bool__ method (line 3367).

Thank you for taking the time to look into this, and I apologize for
that because I just found that it was a false alarm: I apparently
somehow (despite just having rebuilt it) wound up with a
partially-broken PARI, at least I think. After a manual `rm -f
local/lib/*pari*` and rebuilding pari, cypari, and their dependents
everything is fixed now.

Of course, that could indicate a bug in the build system, but I'm not
sure now how I would reproduce the situation. This arose in part
because I was playing around with
https://trac.sagemath.org/ticket/27267

Justin, just to try for another data point for https://groups.google.com/forum/#!topic/sage-devel/pNvpzOH4e1Q could you try running the optional internet tests as well for this one?  Just running --optional=sage,internet on one file, e.g. src/sage/databases/oeis.py should suffice to test this out.  Thanks!

Did that, with attached results (146 failures). Why would “https” be an unknown URL type.

I ran this on two of the systems: 10.11.6 (MBP) and 10.13.6 (iMac Pro).

And the results: same failures (as in the now-attached log). Too much coffee, I suspect.

Thanks, that is helpful - and a different error than what I got.  I gave the gist of this to the relevant sage-devel thread, thank you!
