> Moreover, on Linux, getgrouplist() can also fail with -1 if the group list is too small. In that case, ngroups is updated to the number of groups and so can be used to enlarge the list!
I tested by manually initializing ngroups to a value way lower than MAX_GROUPS (65536 on my Fedora 31): os.getgrouplist() raises OSError() with a random errno, getgrouplist() doesn't set errno on failure.
I wrote PR 19126 to fix the issue on all platforms. The glibc implementation is detected and used: use updated ngroups value (only if it's larger). |
