From 8dda64fa3e1d3249baa948dc0558e3f65d71e6df Mon Sep 17 00:00:00 2001 From: Jakub Konka Date: Tue, 3 Nov 2020 00:36:28 +0100 Subject: Fix Darwin codepath On Darwin, according to the man pages for setrlimit(), when adjusting max number of open fds, the reported hard max by getrlimit() is only theoretical, while the actual maximum, set in the kernel, is hardcoded in the header file. Therefore, the reported max has to be adjusted as `min(OPEN_MAX, lim.max)`.
