Thanks, Volker.

This is on Apple Silicon Macs with Homebrew up to date and make pytest.

On macOS 11.6.7 (Big Sur) with Xcode 13.2.1 and macOS 12.4 (Monterey) with Xcode 13.4.1  make ptestlong gives
----------------------------------------------------------------------
sage -t --long --warn-long 56.2 --random-seed=30333023414362206299073208274839856651 src/sage/modular/overconvergent/hecke_series.py  # Timed out
----------------------------------------------------------------------
which is due to the fact that the following
sage: hecke_series(5, 7, 10000, 5, modformsring=True) # long time (3.4s)
takes forever.  This was not the case for 9.7.beta2.

Otherwise, on macOS 11.6.7 (Big Sur) with Xcode 13.2.1  make ptestlong gives also the usual:
----------------------------------------------------------------------
sage -t --long --warn-long 56.2 --random-seed=30333023414362206299073208274839856651 src/sage/matrix/matrix_gf2e_dense.pyx  # 1 doctest failed

Built, as usual, on two systems (10.14.6, 2017 MBP, 4-core Core i7; 10.15.7, 2019 MBP, 8-core Core i9).

No problems with the builds. Testing (‘ptestlong’) yielded the following problems:

10.14.6: two failures, the usual (for this system) symbolic/integration/external.py; and the recently reported failure of modular/overconvergent/hecke_series.py

10.15.7: one failures, the recently reported failure of modular/overconvergent/hecke_series.py

Logs available if needed.

Thanks for the new release.
On Ubuntu 20.04 running on Xeon E5-2623 + 16 GB RAM:

- build (-j16) from a fresh git clone with system Python (3.8.10): OK (*)
- make ptestlong --> all tests passed except for src/sage/modular/overconvergent/hecke_series.py,

(*) the Ubuntu package python3-venv had to be installed for the system Python to be used, cf.

The calculus one appears that it is not simplifying for me (I get that answer after running simplify_full() on the result). The perm_gps one comes from the optional gap_packages.

I meant to follow up on that. The test has been added in a recent ticket but the result is different between giac 1.7 and giac 1.9. Both results are equivalent but the 1.7 is more compact (simplified?). The failure means you have giac 1.9 installed.

The test was introduced in https://trac.sagemath.org/ticket/25626 and you can see my comment at the end. We need to follow up to make sure the result is tested in a more version independent form.

This might be because my docbuild seems to be stuck in some partial (broken) state as I have messages like

[sagemath_doc_html-none] [finite_ri] updating environment: 0 added, 0 changed, 19 removed

The fact that it thinks file have been removed is slightly troubling to me to what is supposed to be "clean" from the docbuild perspective. Have I missed something with our docbuilding procedures? Is there some way to fix this without a full "make clean" and rebuild? This was from an incremental upgrade.

changes in the modules system of sagelib are being merged.
Chances are that "make clean" (or even distclean) might be necessary.

Try "make doc-clean doc-uninstall", not just "make doc-clean".

Unfortunately that doesn't work for me with the same error (but now it at least it is trying to add the modules). I might have to follow Dima's suggestion and do "make clean" and maybe also reinstall the optional packages with a distclean...

Best,
Travis

FWIW, ditto on a slightly smaller machine (Debia testing running on core i5 + 8 GB RAM).

While ptesting an upcoming ticket (irrelevant here), I got two new permanent errors. The first one is Trac#34029, whose ix is positively_reviewed. The second one is new, as far as I can tell :

pytest is not installed in the venv, skip checking tests that rely on it

checking out develop, I reproduced the same problems. These failures are therefore new develop problems (possibly due to Debian testing evolution) rather than specific to my ticket.
Advice asked on whether and how to file the problem I believe unreported.

It looks to me as if this is caused by the recent eclib upgrade.

Notice that I could compile from the first build with Xcode 13.3. Do you have any idea ?
