Release Notes 2.2

Released on 2020-04-01.

Mock 2.2 new features:

• Mock no more strictly depends on mock-core-configs package, but depends on mock-configs instead. Even though mock-core-configs package still provides mock-configs, other packages may/could too - so users can have alternatives for mock-core-configs (#544).

• /etc/mock/site-defaults.cfg was moved from /etc to %doc, and the config file is now much smaller (and moved to mock-core-configs). Even before the file was meant to be documentation-only (everything commented-out), but since it was also configuration file - with frequent updates in RPM - it was very easy to stop following what's new there (#555).

• New config_opts['isolation'] option invented (alternative to --isolation) to replace boolean config_opts['use_nspawn']. The possible values are nspawn, simple and auto (default). When auto is specified mock tries to use nspawn and if it is not possible, it falls-back to simple chroot. This is useful to make mock work by default in environments like Fedora Toolbox, Podman and Docker. The old use_nspawn option still works, but isolation has preference (#337 and #550).

• The LANG is set to C.UTF-8 by default (and always) for chrooted processes. Previously mock inherited this value from host environment, and defaulted to C.UTF-8 otherwise. This was done to make mock more deterministic, users can change the default by config_opts['environment']['LANG'] (#451).

Mock 2.2 bugfixes:

• Fix for doubled log entries in some situations (#539, RHBZ#1805631).

• Fix to make mock work in Fedora Toolbox even with --bootstrap-chroot (#550).

• Fix for mock in --privileged docker container where os.getlogin() did not work (#551).

• When --bootstrap-chroot is enabled, things like rpm -qa --root ... are executed in bootstrap chroot, instead of on host. This is to assure that the RPM used is compatible with target chroot RPMDB (#525).

• The mock --chroot -- CMD ARG1 ARG2 command was fixed so it works correctly for both --isolation=simple|nspawn and use_bootstrap=True|False, the caveats in --shell and --chroot are now better documented in manual page (#550).

• Mock --chain with --isolation=simple was fixed to work with external URLs (#542).

• Killing of forgotten chrooted processes was made more robust. We now kill also "daemons" started on background during chroot initialization -- when packages are installed to mock chroot and some package scriptlet mistakenly spawns background process (#183).

• The --use-bootstrap-image was fixed to work on EL7 properly (#536).

• Stuff below <bootstrap_root>/tmp is now passed down to mock chroot even with --isolation=nspawn (default). Previously - everything mock prepared below that directory was automatically overmounted by systemd-nspawn. So newly, stuff like --install /tmp/some.rpm or repositories like file:///tmp/test-repo will be correctly used through --bootstrap-chroot. This fix requires new-enough systemd-nspawn which supports $SYSTEMD_NSPAWN_TMPFS_TMP environment variable (#502).

• Mock configuration; the host-local baseurl=file:///some/path/$basearch repositories with dnf variables inside were fixed for --bootstrap-chroot (RHBZ#1815703).

• Mock configuration; the host-local metalink=file:///some/host/file (and mirrorlist) repositories were are fixed for bootstrap (RHBZ#1816696).

• With bootstrap, we use configured yum commands instead of hard-wired /usr/bin/yum (#518).

• The package_state plugin was fixed to cleanup RPMDB before executing rpm -qa. This broke builds on targets with incompatible RPMDB backends before (e.g. OpenMandriva).

Mock-core-configs 32.6

• The site-defaults.cfg config file was moved from mock to mock-core-configs.

• The config_opts['isolation'] is now used instead of config_opts['use_nspawn'], when necessary.

• We declare the minimal version of mock by Requires: now. At this point it is version 2.2+.

• The default bootstrap image was specified for Amazon Linux conifgs.
