![]() * cmd/checksum: prefer url matching url_from_version This is a minimal change toward getting the right archive from places like github. The heuristic is: * if an archive url exists, take its version * generate a url from the package with pkg.url_from_version * if they match * stop considering other URLs for this version * otherwise, continue replacing the url for the version I doubt this will always work, but it should address a variety of versions of this bug. A good test right now is `spack checksum gh`, which checksums macos binaries without this, and the correct source packages with it. fixes #15985 related to #14129 related to #13940 * add heuristics to help create as well Since create can't rely on an existing package, this commit adds another pair of heuristics: 1. if the current version is a specifically listed archive, don't replace it 2. if the current url matches the result of applying `spack.url.substitute_version(a, ver)` for any a in archive_urls, prefer it and don't replace it fixes #13940 * clean up style and a lingering debug import * ok flake8, you got me * document reference_package argument * Update lib/spack/spack/util/web.py Co-authored-by: Adam J. Stewart <ajstewart426@gmail.com> * try to appease sphinx Co-authored-by: Adam J. Stewart <ajstewart426@gmail.com> |

Spack
Spack is a multi-platform package manager that builds and installs multiple versions and configurations of software. It works on Linux, macOS, and many supercomputers. Spack is non-destructive: installing a new version of a package does not break existing installations, so many configurations of the same package can coexist.
Spack offers a simple "spec" syntax that allows users to specify versions and configuration options. Package files are written in pure Python, and specs allow package authors to write a single script for many different builds of the same package. With Spack, you can build your software all the ways you want to.
See the Feature Overview for examples and highlights.
To install spack and your first package, make sure you have Python. Then:
$ git clone -c feature.manyFiles=true https://github.com/spack/spack.git
$ cd spack/bin
$ ./spack install zlib
Documentation
Full documentation is available, or
run spack help
or spack help --all
.
For a cheat sheet on Spack syntax, run spack help --spec
.
Tutorial
We maintain a hands-on tutorial. It covers basic to advanced usage, packaging, developer features, and large HPC deployments. You can do all of the exercises on your own laptop using a Docker container.
Feel free to use these materials to teach users at your organization about Spack.
Community
Spack is an open source project. Questions, discussion, and contributions are welcome. Contributions can be anything from new packages to bugfixes, documentation, or even new core features.
Resources:
- Slack workspace: spackpm.slack.com. To get an invitation, visit slack.spack.io.
- Mailing list: groups.google.com/d/forum/spack
- Twitter: @spackpm. Be sure to
@mention
us!
Contributing
Contributing to Spack is relatively easy. Just send us a
pull request.
When you send your request, make develop
the destination branch on the
Spack repository.
Your PR must pass Spack's unit tests and documentation tests, and must be PEP 8 compliant. We enforce these guidelines with our CI process. To run these tests locally, and for helpful tips on git, see our Contribution Guide.
Spack's develop
branch has the latest contributions. Pull requests
should target develop
, and users who want the latest package versions,
features, etc. can use develop
.
Releases
For multi-user site deployments or other use cases that need very stable software installations, we recommend using Spack's stable releases.
Each Spack release series also has a corresponding branch, e.g.
releases/v0.14
has 0.14.x
versions of Spack, and releases/v0.13
has
0.13.x
versions. We backport important bug fixes to these branches but
we do not advance the package versions or make other changes that would
change the way Spack concretizes dependencies within a release branch.
So, you can base your Spack deployment on a release branch and git pull
to get fixes, without the package churn that comes with develop
.
The latest release is always available with the releases/latest
tag.
See the docs on releases for more details.
