Bug ID: 29917
Summary: getdelim/getline() fail to set ferror on some errors,
violate POSIX
Product: glibc
Version: 2.36
Status: UNCONFIRMED
Keywords: std-posix
Severity: normal
Priority: P2
Component: stdio
Assignee: unassigned at sourceware dot org
Reporter: roman.zilka at gmail dot com
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: x86_64-pc-linux-gnu
Build: x86_64-pc-linux-gnu
POSIX-2017 requires that getdelim/getline() set the stream error indicator upon
error. For some of them glibc won't do that: EINVAL, possibly also ENOMEM and
EOVERFLOW (judging by the sourcecode). The usage example given in POSIX is
unsupported and the hint about feof() and ferror() in Application Usage doesn't
hold.
This is on x86_64 on my distro's 2.36 with libio/ioget{line,delim}.c identical
to those in git.

getdelim: ensure error indicator is set on error (bug 29917)
POSIX requires that getdelim and getline set the error indicator on the
stream when an error occured, in addition to setting errno.
This is fixed in glibc 2.37.
