typo + guava

[GMS103]

This tries to take into account #40484.

@enriqueartal: Could you test it?

⌛ Dependencies

Built on top of #40512.

[GMS103]

I was told nullptr is defined to be 0, so I did not replace the latter with the former.

[enriqueartal]

Built in Fedora 42, the usual failed test for semigroups.rst. Dicriticals are much easier :)

[GMS103]

TL;DR Nothing new.

With
cmake_minimum_required(VERSION 3.25...4.0.3) (present situation)
SageMath version 10.7.beta9 + #40519 gives the following after
./configure --enable-gap_packages --enable-semigroups --enable-symengine

macOS 15.6
make succeeds.
make ptestlong gives 2 errors:

(1)

sage -t --long --warn-long 30.0 --random-seed=… src/doc/en/reference/spkg/semigroups.rst
**********************************************************************
File "src/doc/en/reference/spkg/semigroups.rst", line 15, in doc.en.reference.spkg.semigroups
Failed example:
    libgap.LoadPackage("semigroups")       # optional - semigroups
Expected:
    true
Got:
    #I  ReadPackage could not read <digraphs>/gap/doc.g
    <BLANKLINE>
    true
**********************************************************************

as indicated by DIma.
(2)

sage -t --long --warn-long 30.0 --random-seed=… src/sage/algebras/quantum_groups/quantum_group_gap.py  # 1 doctest failed

related to TikZ (in fact there are some other failed tests, but they pass standalone).

Debian 12
make succeds.
make ptestlong gives the same semigroups.rst error (in fact there are some other failed tests, but they pass standalone).

not sure what you mean here, but it's important to stick to correct types (and in C++ using 0 in place of where nullptr should be by right might be an error - for the latter being 0 is an implementation-dependent artefact)

There are several places where
{0, 0, 0, 0, 0}
appears. Only 2 of them were replaced by Enrique with
{nullptr, 0, nullptr, nullptr, nullptr}
so it would be nice if somebody who knows about it makes the suitable changes.

Same remark as in #40512 (comment)

[GMS103]

Why is conftest.py deleted here? This seems to be a mistake.

Sorry, it is surely my fault, but I do not know how I did it.
Should be back now.

Thanks, Dima.
