https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225434 Bug ID: 225434 Summary: [patch] Treat set but empty environment variables as unset in /usr/libexec/phttpget Product: Base System Version: 11.1-STABLE Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Many People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: vd@FreeBSD.org Keywords: patch Created attachment 190037 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D190037&action= =3Dedit patch to treat set-to-empty environment variables as not-set If http_proxy is set to an empty string in the environment of portsnap, then this is propagated to /usr/libexec/phttpget (which is used by portsnap) and this tool then fails, but the error is silenced and ignored by portsnap, leading to "metadata corrupt" error down the execution of portsnap: root# portsnap --debug --interactive fetch ... Fetching 5 metadata files... /usr/libexec/phttpget ec2-eu-west-1.portsnap.freebsd.org f/34c6... phttpget: host =3D , port =3D 3128: hostname nor servname provided, or not = known Verifying 34c6... /usr/sbin/portsnap: cannot open 34c6....gz: No such file = or directory metadata is corrupt. The mailing lists and forums are littered with similar reports, for example: https://forums.freebsd.org/threads/901/page-2 A shell script may contain http_proxy=3D${http_proxy:-""} in which case http_proxy will be set to an empty string and phttpget should treat that as= if the variable is not set (no proxy provided). --=20 You are receiving this mail because: You are the assignee for the bug.=
