Released on 2018-06-12.

Features:

• Previously you were able to only build for compatible architectures. I.e., you can build i386 package on x86_64 architecture. When you tried to build for incompatible architecture, you get this error:

$ mock -r fedora-28-ppc64le shell
ERROR: Cannot build target ppc64le on arch x86_64, because it is not listed in legal_host_arches ('ppc64le',)

Now, you can build for any architecture using new option –force-arch ARCH. GH#120 You have to have installed package qemu-user-static, which is a new soft dependence. Try this:

$ sudo dnf install qemu-user-static
$ mock -r fedora-28-ppc64le --forcearch ppc64le shell

and you get the prompt in PPC64LE Fedora. You can do this for any architecture supported by QEMU. Note: Do not confuse --forcearch and --arch which are very different options.

• Mock previously only supported GNU Tar. Now Mock supports BSD Tar as well. GH#169 There is a new option in config available:

# You can configure which tar is used (for root cache and SCM plugin)
# valid options are: "gnutar" or "bsdtar"
# config_opts['tar'] = "gnutar"

Be aware that if you created a cache using gnutar then you cannot extract it using bsdtar. Therefore when changing this option, you have to scrub all caches.

• There is a new config option:

# name of user that is used when executing commands inside the chroot
# config_opts['chrootuser'] = 'mockbuild'

This can be changed to different value. E.g., ‘root’. However, be aware that any other value than ‘mockbuild’ is not tested by upstream.

• There is initial support for MicroDnf GH#76 Be aware the due MicroDNF is missing --installroot option, the buildroot and build dependencies are still installed by DNF. These are new options related to MicroDNF:

# config_opts['microdnf_command'] = '/usr/bin/microdnf'
## "dnf-install" is special keyword which tells mock to use install but with DNF
# config_opts['microdnf_install_command'] = 'dnf-install microdnf dnf dnf-plugins-core distribution-gpg-keys'
# config_opts['microdnf_builddep_command'] = '/usr/bin/dnf'
# config_opts['microdnf_builddep_opts'] = []
# config_opts['microdnf_common_opts'] = []
# config_opts['microdnf_command'] = '/usr/bin/microdnf'
config_opts['package_manager'] = 'microdnf'

Right now, Mock does not ship any config which use this package manager.

• There is a new option --spec, which you can use to build an SRPM.

# dnf download --source foo
# rpm2cpio foo.src.rpm | cpio -dimv
(Add/modify compilation flags in .spec file)
# mock --spec foo.spec foo.src.rpm --postinstall
(or)
# mock --spec foo.spec --sources ./

Bugfixes:

• The file /etc/resolv.conf is now empty when networking is disabled. RHBZ#1514028 This reduces timeout when code tries to connect to a network. Note that option config_opts['use_host_resolv'] changed from True to False as networking is disabled by default too. Note that --enable-network automatically set config_opts['use_host_resolv'] to True now.
