Bug 721389

fedpkg-0.5.9.2-1.fc15.noarch

When running fedpkg verrel not connected to TTY (e.g. through pipe from other tool), standard output contains some lines from standard error output. This makes fedkpkg output and underlying (rpmbuild) errors indistinguishable.

Example:

Checkout F-16 tree for `queuegraph' package (queuegraph-1_1-8_fc14-3-g02274d9) and run `fedpkg verrel' with first or second or both descriptors redirected to file and watch difference.


First keep one output on TTY:

$ fedpkg verrel 2>/dev/null
queuegraph-1.1-10.fc16

$ fedpkg verrel 1>/dev/null
sed: can't read /usr/share/selinux/devel/policyhelp: No such file or directory
sed: can't read /usr/share/selinux/devel/policyhelp: No such file or directory


And now redirect both outputs:

$ fedpkg verrel 1>verrel.out 2>verrel.err 
$ cat verrel.out 
sed: can't read /usr/share/selinux/devel/policyhelp: No such file or directory

queuegraph-1.1-10.fc16
$ cat verrel.err
sed: can't read /usr/share/selinux/devel/policyhelp: No such file or directory
sed: can't read /usr/share/selinux/devel/policyhelp: No such file or directory


As you can see the second case makes scripting fedpkg unhappy as you get the fedpkg answer mixed with other stuff.

Please change fedpkg to get outputs in the second case the same as in the first case.
