- 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.

|
|

|

|
|
Released on 2020-02-07.
|
|
|
|
## Mock 2.0 highlights:
|
|
|
|
* The mock versioning policy (or rather style) has changed from three to
|
|
two-number pattern. Don't panic, this isn't really special major
|
|
release - the change was only done to move from the
|
|
`<UNUSED>.<MAJOR>.<MINOR>` pattern to `<MAJOR>.<MINOR>`, so practically
|
|
we went with *v2.0* instead of previously planned *v1.5.0*.
|
|
|
|
* The `--bootstrap-chroot` option is newly enabled by default, this can be
|
|
disabled by `--no-bootstrap-chroot`, or by
|
|
`config_opts['use_bootstrap'] = False`. The content of bootstrap chroot
|
|
is cached by default and never automatically updated, but one
|
|
can use the new `--scrub=bootstrap` to remove related caches. The
|
|
`--scrub=all` was updated to clean bootstrap as well (but `--clean`
|
|
doesn't touch bootstrap chroot at all).
|
|
|
|
* The `use_bootstrap_container` configuration option was renamed to
|
|
`use_bootstrap` to better describe it's purpose (it never implied usage
|
|
of container technology) and to align with `use_bootstrap_image`
|
|
option. Please migrate your custom configuration.
|
|
|
|
* The output from `--debug-config` option now only shows the differences
|
|
from mock's defaults, and the output doesn't have the Jinja templates
|
|
expanded.
|
|
|
|
* The `config_opts['dnf.conf']` replaced `config_opts['yum.conf']`. Both
|
|
still work, but only one of them can exist one config file.
|
|
|
|
* The `--old-chroot` and `--new-chroot` options were obsoleted by
|
|
`--isolation=chroot|nspawn`, and still default to `--isolation=nspawn`.
|
|
Please migrate your tooling.
|
|
|
|
* Mock now can now pre-configure DNF variables ([#346](../issues/346)), e.g.
|
|
`config_opts['dnf_vars'] = { 'stream': '8-stream' }`
|
|
|
|
* The regression in `--use-bootstrap-image` implementation was fixed (did
|
|
not work at all in `v1.4.21`), and should work reliably now (`podman`
|
|
still needs to be installed manually to make it work).
|
|
|
|
* In mock config files we now prefer Jinja templates, instead of
|
|
previously used python expansion `"%(variable)" % ..`. It is not
|
|
likely, but if you use this in your custom config files, please
|
|
migrate.
|
|
|
|
## Mock 2.0 other fixes and enhancements:
|
|
|
|
* Loop device files are pre-populated even in `--isolation=nspawn`
|
|
chroots, similarly to what is done with `--isolation=chroot`
|
|
([#298](../issues/298)).
|
|
|
|
* The `include()` statement in mock config now also accepts relative path
|
|
names (relative against `config_opts['config_path']` for now).
|
|
|
|
* The host local repositories from mock config files
|
|
(like `baseurl=file://`) are now correctly bind-mounted to bootstrap
|
|
chroot. So installing RPM from such repositories with
|
|
`--bootstrap-chroot` now works (related [#381](../issues/381)).
|
|
|
|
* Non-interactive commands in chroot are executed through
|
|
`systemd-nspawn --console=pipe` (when `--isolation=nspawn`, default)
|
|
([#432](../issues/432)).
|
|
|
|
* Better detection of host's package manager (DNF vs. YUM), for both
|
|
bootstrap and normal chroot. This should demotivate people from using
|
|
`--dnf` and `--yum` options ([#233](../issues/233)). More, on Fedora 31+ there's no
|
|
real YUM package manager anymore (there only is `yum.rpm` which actually
|
|
provides `/bin/yum` symlink to `/bin/dnf`). This situation is now
|
|
properly detected in mock, and the symlink is ignored (we fallback to
|
|
DNF).
|
|
|
|
* Better re-using of DNF/YUM caches, in both normal and bootstrap chroot.
|
|
This is mostly given by previous bullet (YUM vs. DNF detection). To be
|
|
100% sure, we also newly rather bind-mount both DNF and DNF cache
|
|
directories into the chroot.
|
|
|
|
* Mock expands the config templates (aka `include()`) completely before
|
|
executing it by eval(), and the implementation is now much simpler and
|
|
clear.
|
|
|
|
* Mock doesn't ignore `cleanup_on_success` configuration option after
|
|
`--postinstall` action.
|
|
|
|
* `mock --chain` file descriptor leak was fixed, so the descriptor usage
|
|
is constant with multiple builds.
|
|
|
|
* The Jinja templating is now iteratively re-rendered (when Jinja template
|
|
expands to another Jinja template), till there is something to expand. Also
|
|
we start the Jinja rendering mechanism a bit earlier in the codebase so the
|
|
mock configuration isn't really order-dependant (no matter which
|
|
configuration option is set first).
|
|
|
|
* Fix lvm plugin volume removal feature on modern systems
|
|
([rhbz#1762728](https://bugzilla.redhat.com/1762728)).
|
|
|
|
* We don't install `shadow-utils` (we don't need this one) and
|
|
`distribution-gpg-keys` (we copy the keys from host instead), so this
|
|
makes the initial `dnf_install_command` transaction shorter, and more
|
|
reliable across all the variety distributions we support.
|
|
|
|
* The `--sources` parameter is not mandatory in `--buildsrpm` mode.
|
|
|
|
* Mock now copies `/etc/pkg/ca-trust/extracted` into chroot
|
|
([#397](../issues/397)).
|
|
|
|
* The `success` and `fail` files are created under mockbuild user, not root.
|
|
|
|
* The `compress_logs`, when turned on, have predefined default `gzip` method.
|
|
|
|
* We turned `--forcearch` on long time ago, but mock exited with cryptic
|
|
error when `qemu-user-static` wasn't installed. Mock now detects that
|
|
`qemu-user-static` is missing and throws instructions instead.
|
|
|
|
|
|
## Mock-core-configs 32.0
|
|
|
|
* Added configs for **Fedora 32**, Fedora Rawhide configs moved to F33. The new
|
|
package depends on updated **distribution-gpg-keys 1.36** package (avaiable
|
|
in Fedora updates at the time of release).
|
|
|
|
* Fedora 29 configs EOLed (moved below `eol` subdirectory).
|
|
|
|
* All the configuration files were modified to use templates, to de-duplicate
|
|
a lot of stuff and many inconsistencies were fixed.
|
|
|
|
* On el7, mock/mock-core-configs automatically enable `use_bootstrap_image`
|
|
option for **Fedora 31+** chroots (ZSTD compression enabled for RPMs) because without
|
|
this option it wouldn't make sense to do anything (neither bootstrap chroot
|
|
is installable).
|
|
|
|
Both mock and mock-core-configs packages need to be updated together as pair.
