Release 2021.2

Client side changes

The client now supports a --register-driver command which will be used by Fedora CoreOS and zincati.service to tell rpm-ostree that another service is actively "driving" updates. In concert with this, rpm-ostree upgrade now emits an error message if a driver is active.
PRs: #2459 and #2566

Compose

There is a new rpm-ostree compose extensions which will be used by RHEL CoreOS, but is intended to be generally usable by rpm-ostree users that want to more cleanly split their builds into "base OS image" + "optional extensions (RPMs)", while reusing the same declarative manifest format.
PR: #2439

Core changes

rpm-ostree now better supports a newer libsolv that uses %{_dbpath} to find the rpm database.
(This fix was already backported into Fedora)
Issue: #2548

Internals

Change main entrypoint to be Rust is a huge milestone - rpm-ostree is now a Rust application with an internal C++ library. We now do bidirectional calls. The transition to Rust is accelerating!

Other oxidation progress:

  • Much of the code around handling /etc/{passwd,group} is now in Rust; PR: #2580

A lot of CI fixes and cleanups; most notably we now test some with AddressSanitizer which caught one bug.

rpm-ostree ex apply-live

In this release, the functionality formerly known as rpm-ostree ex livefs is now known as rpm-ostree ex apply-live, and it's been placed on a much firmer technical foundation and is considered much safer to use. It's still under ex because we may make some interface changes, and we hope to gather feedback.

Concretely apply-live now uses a "transient" overlayfs instead of mutating any persistent filesystem. This makes it robust against power loss while the running filesystem is being changed. We no longer push a rollback deployment, etc. Stated a different way: if something goes wrong, all you need to do is reboot.

Countme support

rpm-ostree now ships an rpm-ostree-countme.timer unit which fulfills the same purpose as the DNF countme feature. This will allow Fedora counting of installed systems to include rpm-ostree-based variants like Fedora CoreOS, Fedora Silverblue, and Fedora IoT, while still preserving user privacy.

Note the unit is currently not enabled by default. For more information, including how to disable it, see the docs.

override replace directly from Bodhi/Koji

Another notable feature in this release is support for directly pulling builds from current Fedora testing/build tools Bodhi and Koji.

Now with rpm-ostree v2021.1 you can run e.g.:

$ rpm-ostree override replace https://bodhi.fedoraproject.org/updates/FEDORA-2020-2908628031

to directly pull in a single Bodhi update applied relative to your booted system (presumably a stable stream) without changing anything else. You can also pull in Koji builds (that may or may not be in a Bodhi update):

$ rpm-ostree override replace https://koji.fedoraproject.org/koji/buildinfo?buildID=1625029

This allows you to more directly interact with Bodhi's current model of testing individual updates.

Note that like all usage of override replace, these versions are "pinned" until explicitly removed with a variant of rpm-ostree override reset.

(This does combine with apply-live so you can more easily test out changes)

Default to sqlite in F34+

Fedora 34 rpm-ostree based systems will switch to the sqlite backend by default, silencing a warning about use of the bdb backend.

Shared library "hollowed out"

Quite a while ago rpm-ostree started shipping a shared library librpmostree-1.so.1.0.0; mainly it's used by e.g. gnome-software to display package diffs between ostree commits. However this created a problem later because we duplicated a lot of code between our binary and the shared library, and that in turn caused unnecessary bloat. The build system and implementation of the shared library was reworked to fork off the binary and parse its output. This reduced the size (debug symbols stripped) from ~2.6MB to 320k (-~88%).

Internals: FFI and Rust

Large portions of rpm-ostree have already been ported to the Rust programming language, in order to improve the overall level of safety and resilience of the project.

To further accelerate this transition, since the last release we are using cxx.rs as a code generation helper, which has the compelling feature of supporting fully safe bidirectional calls between C++ and Rust.

This required switching the C code to "C that builds in C++ mode". For the sake of clarity though, the goal here is to accelerate our transition to Rust, not to rewrite rpm-ostree code in modern C++.

There is a new ex initramfs-etc command that can be used
to inject local configuration from /etc into an additional initramfs
image. This is still experimental, but we plan to use it
for "complex root devices" for Fedora CoreOS at least, and it can
also be used for cases like dracut LUKS keyboard layouts.
PR: #2170

The "rojig" (embed ostree in RPM) functionality is now
disabled by default.
(If you are using it, please tell us!)

Ensure you're using boot-location: modules, as the current default
boot-location: new is deprecated.
The only reason to use boot-location: new is if you care
about upgrading directly from very old versions of ostree.
At some point it's likely that this configuration option will
be removed entirely.

This release also contains portability bugfixes (for 32bits ARM) and
improvements to the transaction logic, enhancing overall reliability.

Documentation is cleaned up and moved from readthedocs.io to
Github pages, the new site is: https://coreos.github.io/rpm-ostree/

Various CI fixes.

Various Rust cleanups (particularly around FFI).

This is mostly a bugfix release.

One important fix is adapting to the change in Fedora to transition the rpmdb
to SQLite
. This would
result in Fedora 33 composes using the new backend, making it harder for users
with layered packages to rebase (see
bugzilla.redhat.com/show_bug.cgi?id=1876194#c3).

As a result, there is now an rpmdb key in the treefile which can take e.g.,
bdb or sqlite but which defaults to bdb. This means that f33 composes
will for now keep using BDB, allowing for smoother rebases. Content providers
can opt into the new SQLite backend when convenient.

Another fix worth mentioning is a major improvement in how layered packages are
handled: rpm-ostree now correctly picks older versions of layered packages if
needed to satisfy base packages. This will help solve the "split base/layered
package mismatch"
in
combination with pending work in Fedora at least to publish older versions of
RPMs. Additionally, when a solution is not possible, the error message prints
exactly what the conflict is.

Otherwise, there is the usual churn around CI. For example, the MSRV is now
1.45.2. There are some preparations for using
ostree-rs more extensively in the future.

Minor release with some fixes and enhancements for RHCOS.

Server

A symlink from /usr/lib/sysimage/rpm to the rpmdb was added (PR #2154). This
will eventually be the new standard location for the rpmdb on multiple
image-based distros. See this
thread
for
details.

Treefiles now support package requests with version requirements again
(PR #2151). Must be quoted, e.g.:

packages:
  - foo bar 'baz > 1.0'
  - 'boo <= 3.2'

Client

Multiple commands learned the --lock-finalization switch which deploy
already understood (PR #2158). This is used in FCOS and may end up being used in
RHCOS as well.

Fix a potential segfault when upgrading from a local repo, i.e. via rebase /path/to/repo:$rev (PR #2178).

Release 2020.3

This is a thin release overall, with mostly bugfixes and minor tweaks.

  • rpm-ostree compose tree will now print a warning and incur a 5s delay when not using --unified-core. This is part of our push to eventually making it the default. If you cannot make use of --unified-core right now and want to avoid the delay, there is an undocumented environment variable you can find. Please follow up to #729 if you need assistance! PR #2098

  • rpm-ostree rebase /path/to/local/repo:ref is no longer considered experimental. This has been actively used by RHCOS on OCP4 for a while now. PR #2110

  • Fix a bug in the upgrader where downgrade protection would mistakenly kick in if deploying to a new version that was older than whatever the latest version was last pulled. PR #2096

  • Work around the latest f32 crypto-policies using a Lua scriptlet, which we do not yet support, and leaking FIPS mode from the server into composes. PR #2136

  • Fix building on platforms without zchunk support, like RHEL8. PR #2092

Colin Walters (9):
      build-sys: Disable zchunk for libdnf if we don't have it
      compose: Remove --output-repodata-dir
      compose: Add a "warn and sleep" if --unified-core is not provided
      tests/kola: Move into tests/kolainst, run installed
      rojig-build: Just expand %_isa
      test-override-kernel: Support f32
      daemon: Add an error prefix in local repo pulls
