# Recommended update for spack
Announcement ID: SUSE-RU-2024:0452-1
Rating: moderate
References:
* bsc#1219480
Affected Products:
* openSUSE Leap 15.3
* SUSE Linux Enterprise High Performance Computing 15 SP3
* SUSE Linux Enterprise High Performance Computing LTSS 15 SP3
An update that has one fix can now be installed.
## Description:
This update for spack fixes the following issues:
spack was updated to version 0.21.1 (bsc#1219480):
* Version 0.21.1:
* Add support for reading buildcaches created by Spack v0.22
* Bugfixes:
* `spack graph`: fix coloring with environments
* `spack info`: sort variants in --variants-by-name
* `Spec.format`: error on old style format strings
* ASP-based solver:
* fix infinite recursion when computing concretization errors
* don't error for type mismatch on preferences
* don't emit spurious debug output.
* Improve the error message for deprecated preferences
* Fix multi-word aliases
* Add a warning for unconfigured compiler
* environment: fix an issue with deconcretization/reconcretization of specs
* buildcache: don't error if a patch is missing, when installing from binaries
* Version 0.21.0:
* New features:
* Better error messages with condition chaining: In v0.18, we added better error messages that could tell you what problem happened, but they couldn't tell you why it happened. 0.21 adds condition chaining to the solver, and Spack can now trace back through the conditions that led to an error and build a tree of causes potential causes and where they came from.
* OCI build caches: You can now use an arbitrary OCI registry as a build cache:
* For Dockerhub:
`$ spack mirror add my_registry oci://user/image`
* For another registry (GHCR):
`$ spack mirror add my_registry oci://ghcr.io/haampie/spack-test`
Then set the login credentials:
`$ spack mirror set --push --oci-username ... --oci-password ... my_registry`
and push to it:
`$ spack buildcache push my_registry [specs...]`
You can optionally add a base image to get runnable images:
`$ spack buildcache push --base-image leap:15.5 my_registry python` Pushed ...
as [image]:python-3.11.2-65txfcpqbmpawclvtasuog4yzmxwaoia.spack $ docker run
--rm -it [image]:python-3.11.2-65txfcpqbmpawclvtasuog4yzmxwaoia.spack`
This creates a container image from the Spack installations on the host system,
without the need to run `spack install` from a `Dockerfile` or `sif` file. It
also addresses the inconvenience of losing binaries of dependencies when `RUN
spack install` fails inside `docker build`. Further, the container image layers
and build cache tarballs are the same files. This means that `spack install` and
`docker pull` use the exact same underlying binaries. If you previously used
`spack install` inside of docker build, this feature helps you save storage by a
factor two. \+ Multiple versions of build dependencies: Increasingly, complex
package builds require multiple versions of some build dependencies. For
example, Python packages frequently require very specific versions of
`setuptools`, `cython`, while different physics packages require different
versions of Python to build. The concretizer enforced that every solve was
unified, i.e., so that there was only one version of every package. The
concretizer now supports "duplicate" nodes for build dependencies, but enforces
unification through transitive link and run dependencies. This will allow it to
better resolve complex dependency graphs in ecosystems like Python. \+ Cherry-
picking virtual dependencies: You can now select only a subset of virtual
dependencies from a spec that may provide more. For example, to make mpich your
mpi provider, you can be explicit by writing:
`hdf5 ^[virtuals=mpi] mpich`
Or, to use, e.g., `intel-parallel-studio` for blas along with an external
`lapack` like `openblas`, you could write:
`strumpack ^[virtuals=mpi] intel-parallel-studio+mkl ^[virtuals=lapack]
openblas``
The `virtuals=mpi` is an edge attribute, and dependency edges in Spack graphs
now track which virtuals they satisfied. \+ The `spack deconcretize` command
gives you control over what you want to update in an already concrete
environment. As an example, with an environment built with meson, and you want
to update your meson version, you can run:
`$spack deconcretize meson`
and have everything that depends on meson rebuilt the next time you run spack
concretize. In the future, we'll handle this in a single command, but for now
you can use this to drop bits of your lockfile and resolve your dependencies
again. \+ UI Improvements: The `spack info` received a rework to make the output
more appealing. It is now on par with the rest of Spack's UI. `spack info` now
makes much better use of terminal space and shows variants, their values, and
their descriptions more clearly. Conditional variants are grouped separately so
you can more easily understand how packages are structured. `spack checksum` now
allows you to filter versions from your editor, or by version range. It also
notifies you about potential download URL changes. \+ Environments can include
definitions: Spack did not previously support using `include:` with The
definitions section of an environment, but now it does. You can use this to
curate lists of specs and more easily reuse them across environments. \+
Aliases: You can now add aliases to Spack commands in `config.yaml`, e.g. this
might enshrine your favorite args to `spack find` as `spack f`:
`config: aliases: f: find -lv`
* Improved autoloading of modules: In this release, you can start using `hide_implicits: true` instead, which exposes only explicitly installed packages to the user, while still autoloading dependencies. On top of that, you can safely use `hash_length: 0`, as this config now only applies to the modules exposed to the user -- you don't have to worry about file name clashes for hidden dependencies. Note: for Tcl this feature requires Modules 4.7 or higher
* Other new commands and directives:
* `spack env activate` without arguments now loads a default environment that you do not have to create.
* `spack find -H` / `--hashes`: a new shortcut for piping spack find output to other commands.
* Add `spack checksum --verify`, fix `--add`.
* New `default_args` context manager factors out common args for directives.
* `spack compiler find --[no]-mixed-toolchain` lets you easily mix clang and gfortran on Linux
* Performance improvements:
* `spack external find execution` is now much faster.
* `spack location -i` is now much faster on success.
* Drop redundant rpaths post install.
* ASP-based solver: avoid cycles in clingo using hidden directive.
* Fix multiple quadratic complexity issues in environments
* Other new features of note:
* archspec: update to v0.2.2, support for Sapphire Rapids, Power10, Neoverse V2.
* Propagate variants across nodes that don't have that variant
* Implement fish shell completion.
* Can now distinguish between source/binary mirror; don't ping mirror.spack.io as much.
* Improve status reporting on `spack install` (add [n/total] display...).
