default	Release Notes - Mock v3.0

Released on 2022-04-07.

Mock v3.0 changes:

• Mock v2.* releases of Mock were supported on Enterprise Linux 7+. Since this version v3.0, the prerequisite is Enterprise Linux 8 or newer. Mock for the Enterprise Linux 7 is still supported in the mock-2 branch upstream, but it will only receive bug fixes.

  This only affects the Mock RPM installation, i.e. the host EL7 operating system where Mock is run. Building packages for the target Enterprise Linux 7 chroots continues to be supported in Mock v3.X. More info in the original issue.

• The minimal runtime requirement now is Python 3.6.

• Mock has a new command --list-chroots which prints the list of available chroots with short descriptions (PR#869). It will go through both system-wide configuration files in /etc/mock and users' configuration in ~/.config/mock/. The output looks like:

  $ mock --list-chroots

  Custom configs:
  
  mockbuild.exception.ConfigError: Could not find included config file: /etc/mock/foohkhk
  
  fedora-50-x86_64                   error during parsing the config file
  fedora-rawhide-python39            Fedora Rawhide
  Finish: run
  

  In this example, the fedora-50-x86_64 is a user's configuration file which has some syntax issue(s).

• There is a new function mockbuild.config.simple_load_config(name) available. You should use it if you want to parse Mock's configuration files. The use is as simple as:

  >>> from mockbuild.config import simple_load_config
  >>> config_opts = simple_load_config("fedora-rawhide-x86_64")
  >>> config_opts["resultdir"]
  '/var/lib/mock/fedora-rawhide-x86_64/result'
  

• the hw_info plugin now reports utilization of volume with cachedir directory.

• Source CA certificates found in /usr/share/pki/ca-trust-source are now automatically copied from host to the target chroot, together with the /etc/pki/ca-trust (PR 864).

• bash completion for --scrub and --short-circuit has been improved.

• SECCOMP was disabled for systemd-nspawn before, and newly we disable it for Podman commands by default, too (PR 885).

  The SECCOMP rules (syscall allow-lists) maintained in those tools are often different across distributions or even distro versions. Because Mock does cross-distribution builds, the "host" distro rules are not always applicable on the "target" distribution. To not complicate things, and because by design Mock doesn't have to fully isolate, we disable SECCOMP for those containerization tools by default. But if you want to enable it, you can now do it using:

  config_opts["seccomp"] = True
