https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D280170 Bug ID: 280170 Summary: FreeBSD clang over sshfs changes date of input files, causing always-recompile Product: Base System Version: 14.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: avuai@gmx.de To reproduce: go into a directory that was mounted with sshfs echo "int a;" > my.c (empty file is not affected) note its modification date with ls -l wait until next minute or set a past timestamp using touch -m clang -c my.c note that my.c's modification date was changed by clang This causes a Makefile to always recompile I don't know whether the root cause is Clang or sshfs but it does not occur when nano opens my.c It does not occur on Linux when I reverse the sshfs direction between my machines, but see version differences below FreeBSD clang version 18.1.5 FreeBSD: sshfs --version SSHFS version 3.7.3 FUSE library version 3.16.2 using FUSE kernel interface version 7.38 mount_fusefs [fuse4bsd] version: 0.3.9-pre1 Linux clang: Ubuntu clang version 14.0.0-1ubuntu1.1 Linux: sshfs --version SSHFS version 3.7.1 FUSE library version 3.10.5 using FUSE kernel interface version 7.31 fusermount3 version: 3.10.5 --=20 You are receiving this mail because: You are the assignee for the bug.=
