The typical initialization of PyMutex in its comment document cannot be compiled on Windows #115304
Description
Activity
I don't understand the links above.
pycore_lock.h, 28-29, are as listed, but have nothing obvious to do with commit 2939ad0 for a pydoc fix. Neither do those lines have any obvious connections with the compile error inrandom_value *= 1082527;in rotatingtree.c. The build report is not obviously linked back to a particular PR.Hi @terryjreedy the compile error in the link should be:
3>D:\a\cpython\cpython\Modules\rotatingtree.c(19,16): error C2099: initializer is not a constant [D:\a\cpython\cpython\PCbuild\pythoncore.vcxproj](I'll update this to the first comment, sorry I forgot it yesterday)And change the usage to
PyMutex m = {0};got compile passed on Windows, see the commits in #115301commit 2939ad0 have no connections to this issue, I guess you mixed this with other issues?
