[roottest] Fix invalid setattr call in test

guitargeek · guitargeek · commit 3fae13e4aaba · 2025-12-09T14:47:23.000+01:00
The `setattr` function requires three arguments, not two. Forgetting the `gbl` variable for which the attribute should be set resulted in pretty nonsensical code, which tried to set attributes of string literals. Maybe this was the result of the nighly failure on Fedora 42, where no ROOT/cppyy was in the stack trace at all. The `_PyErr_SetString` clearly told us that the crash happens in the formatting of the error message of some of the expected exceptions. So the call to `setattr` that is invalid for two reasons (wrong number of args, trying to set attribute of immutable string literal) is my best guess. ```txt 381/3712 Test #1851: roottest-python-basic-datatype ....................................................................***Failed 7.54 sec Info in <TUnixSystem::ACLiC>: creating shared library /github/home/ROOT-CI/build/roottest/python/basic/./DataTypes_C.so -- TEST COMMAND -- cd /github/home/ROOT-CI/build/roottest/python/basic /usr/sbin/timeout -s USR2 270s /py-venv/ROOT-CI/bin/python3.13 /github/home/ROOT-CI/src/roottest/python/basic/PyROOT_datatypetest.py --fixcling -- BEGIN TEST OUTPUT -- ============================= test session starts ============================== platform linux -- Python 3.13.9, pytest-9.0.2, pluggy-1.6.0 rootdir: /github/home/ROOT-CI/src configfile: pyproject.toml plugins: anyio-4.12.0 collected 24 items ../../../../src/roottest/python/basic/PyROOT_datatypetest.py ...........
