[Bug libc/4656] FILE* operations are not robust enough with signals
------- Additional Comments From nix at esperi dot org dot uk 2007-09-22 19:40 -------
This patch turns out to be a seriously bad idea, because no other libcs
preserve the stdio buffer state on error. At least bash, zsh, and rpc.mountd in
all released versions of nfs-utils are known to fail with this patch applied,
with rpc.mountd failing in such a way that NFS service appears to entirely fail
because no fhs can be validated. (Also several of glibc's own tests fail.)
Ideally you'd think it would be better: it's avoiding data loss. But a lot of
programs are *expecting* data loss in this situation, and avoiding it makes
them misbehave...
