[Bug 1135152] New: user: Current not implemented on linux/amd64

[Red Hat Bugzilla]

https://bugzilla.redhat.com/show_bug.cgi?id=1135152

            Bug ID: 1135152
           Summary: user: Current not implemented on linux/amd64
           Product: Fedora
           Version: 20
         Component: golang
          Assignee: vbatts(a)redhat.com
          Reporter: adam(a)spicenitz.org
        QA Contact: extras-qa(a)fedoraproject.org
                CC: admiller(a)redhat.com, golang(a)lists.fedoraproject.org,
                    lemenkov(a)gmail.com, lsm5(a)fedoraproject.org,
                    renich(a)woralelandia.com, s(a)shk.io, vbatts(a)redhat.com



Description of problem:
golang seems to be using some cross-compiled components which are causing
problems. Specifically, Fedora has exactly the problem described here:
http://stackoverflow.com/questions/20609415/cross-compiling-user-current-...

Here is the sample code from that page:

package main

import (
    "fmt"
    "os/user"
)

func main() {
    fmt.Println(user.Current())
}


You can build the sample code and see the problem directly:

$ go build ./current.go
$ ./current 
<nil> user: Current not implemented on linux/amd64



Version-Release number of selected component (if applicable):
golang-1.2.2-22.fc20.x86_64


How reproducible:
Always

If one downloads golang from golang.org (http://golang.org/dl/ the tar.gz
"go1.4.1.linux-amd64.tar.gz", and use that, the bug is not there.  This is a
fedora build failure:

--- Comment #3 from Vincent Batts <vbatts(a)redhat.com&gt; ---
"""
os/user relies on cgo, and cgo is disabled for cross compiling,
thus this is expected.

if you use os/user, you must compile natively on OS X.

even if we enable cross compilation cgo support, I doubt everybody have
a working OS X cross toolchain on their linux machine.

ah, i see. this has to deal with the artifacts chosen by koji when the rpm is
built across the arm, i386 and x86_64 builders. argh.

Can you test this on the go1.5 build that is in f23/f24(rawhide)?

--- Comment #8 from Nalin Dahyabhai <nalin(a)redhat.com&gt; ---
Both claim to require a matching build of golang-src that doesn't exist.  If I
use --nodeps to install the f23 package on x86_64, the sample code builds and
runs, printing out the expected contents of a User struct describing my
logged-in user:
   &{1000 1000 nalin Nalin Dahyabhai /home/nalin} <nil>

This also breaks LXD (friendly LXC wrapper) on Fedora

there are several rpms to update (golang, golang-bin, golang-src), not just a
single rpm. Download them all, and `rpm -Uvh golang*rpm`.

Ah, they're noarch, so I missed them when downloading them with koji
download-build.  Same result: they work.

--- Comment #12 from Vincent Batts <vbatts(a)redhat.com&gt; ---
right, so go1.5 fixes this. Presently on f23 and rawhide. Soon we can roll this
out safely to el6 and prior fedora releases.

--- Comment #14 from Fedora End Of Life <endoflife(a)fedoraproject.org&gt; ---
This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '21'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 21 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

--- Comment #16 from Fedora End Of Life <honza.kurik(a)gmail.com&gt; ---
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
