- Add mock-specific build artifacts (chroot/, mock-*, mockroot/) - Include package build files (*.deb, *.changes, *.buildinfo) - Add development tools (.coverage, .pytest_cache, .tox) - Include system files (.DS_Store, Thumbs.db, ._*) - Add temporary and backup files (*.tmp, *.bak, *.backup) - Include local configuration overrides (config.local.yaml, .env.local) - Add test artifacts and documentation builds - Comprehensive coverage for Python build system project This ensures build artifacts, chroot environments, and development tools are properly ignored in version control.

title: Release Notes - Mock v4.0
|
|
---
|
|
|
|
Released on 2023-05-22.
|
|
|
|
## Mock v4.0 new features:
|
|
|
|
- The RPM Software Management team(s) work hard on the [DNF5][] project, which
|
|
is planned to be the [default package manager in F39][]. Compared to [DNF4][],
|
|
DNF5 is a from-scratch rewritten software, implying that features and
|
|
command-line options might be implemented differently. That's why Mock needed
|
|
a special logic to support it. While DNF5 is still not the default at this
|
|
moment, Mock 4+ supports it and allows users to experiment:
|
|
|
|
```
|
|
$ mock -r fedora-rawhide-x86_64 --config-opts=package_manager=dnf5 --shell
|
|
```
|
|
|
|
When used like this, Mock installs DNF5 package manager into the bootstrap
|
|
chroot first (using DNF5 itself, if found on host, or just using DNF4).
|
|
Later, using DNF5 from bootstrap, installs the target Rawhide buildroot.
|
|
|
|
- The [--use-bootstrap-image](Feature-container-for-bootstrap) feature,
|
|
implemented using the containerization [Podman][] command-line tooling, did
|
|
not work correctly if Mock itself was run
|
|
[in container](index#mock-inside-podman-fedora-toolbox-or-docker-container).
|
|
At the time of releasing Mock 4.0, running nested Podman containers still
|
|
requires quite a lot of
|
|
[configuration done in the image](https://github.com/containers/podman/blob/36510f6/contrib/podmanimage/stable/Containerfile).
|
|
So the requirements were relaxed to not run Podman containers, but only
|
|
extract the container images using the [podman image mount][PR#1073] feature.
|
|
So now, the `--use-bootstrap-image` feature works if Mock is run in Podman.
|
|
|
|
- Mock historically called the `useradd` utility with `-n` option to not create
|
|
the default `mock` group in the chroot. The `-n` option has been a Red Hat
|
|
Enterprise Linux downstream patch, later implemented upstream as `-N`. The
|
|
`-N` option is now supported almost everywhere (since RHEL 6+). If you build
|
|
for older chroots than Enterprise Linux 6 (EOL nowadays), you might need to
|
|
modify the `config_opts["useradd"]` option.
|
|
|
|
## Mock v4.0 bugfixes:
|
|
|
|
- The "essential" mount-points (`/proc`, `/sys`, ..) were not correctly mounted
|
|
to the target buildroot at the time of its installation/initialization (when
|
|
package manager from bootstrap chroot is used to install the buildroot
|
|
packages). This wasn't very obvious, because, during the later phases of Mock
|
|
builds, Mock had those essential mount points mounted. This caused issues
|
|
with the installation of packages that relied on their existence, see
|
|
[rhbz#2166028].
|
|
|
|
- Before killing the leftover in-chroot processes, older Mock versions first
|
|
unmounted (well at least it tried) the mounted filesystems in the chroot.
|
|
This has been fixed, and Mock does it vice-versa so both unmounting itself is
|
|
less likely to have problems and killing the processes is easier.
|
|
|
|
- Mock ignored the `bootstrap_` prefixed `config_opts` options, especially
|
|
useful on commandline for debugging (e.g.
|
|
`--config-opts=bootstrap_chroot_additional_packages=package-foo`). The
|
|
configuration option logic
|
|
[was adjusted](https://github.com/rpm-software-management/mock/commit/8bd4adcaa197af4a7b6a915a01484c51d1c1cc5b)
|
|
to fix this problem.
|
|
|
|
- The manual page of Mock was fixed so users are now instructed to fill issues
|
|
against the GitHub upstream [Mock project](https://github.com/rpm-software-management/mock/issues),
|
|
not the Red Hat Bugzilla.
|
|
|
|
## mock-core-configs-38.5-1
|
|
|
|
- Fedora 35 and 36 are now EOL, so the configuration was moved
|
|
- The `includepkgs=devtoolset*` options were
|
|
[dropped](https://github.com/rpm-software-management/mock/pull/1042) from the
|
|
SCL-related CentOS 7 configuration. This allows the installation of other SCL
|
|
packages during package build (specified by `BuildRequires:`).
|
|
- The `useradd` override configuration was removed as it is not needed now,
|
|
Mock v4.0 now uses `useradd -N` (not `useradd -n`) by default.
|
|
- The openSUSE i586 repos have been moved out of the main repos into a port.
