-
-# v0.20.0 (2023-05-21)
-
-`v0.20.0` is a major feature release.
-
-## Features in this release
-
-1. **`requires()` directive and enhanced package requirements**
-
-   We've added some more enhancements to requirements in Spack (#36286).
-
-   There is a new `requires()` directive for packages. `requires()` is the opposite of
-   `conflicts()`. You can use it to impose constraints on this package when certain
-   conditions are met:
-
-   ```python
-   requires(
-       "%apple-clang",
-       when="platform=darwin",
-       msg="This package builds only with clang on macOS"
-   )
-   ```
-
-   More on this in [the docs](
-     https://spack.rtfd.io/en/latest/packaging_guide.html#conflicts-and-requirements).
-
-   You can also now add a `when:` clause to `requires:` in your `packages.yaml`
-   configuration or in an environment:
-
-   ```yaml
-   packages:
-     openmpi:
-       require:
-       - any_of: ["%gcc"]
-         when: "@:4.1.4"
-         message: "Only OpenMPI 4.1.5 and up can build with fancy compilers"
-   ```
-
-   More details can be found [here](
-     https://spack.readthedocs.io/en/latest/build_settings.html#package-requirements)
-
-2. **Exact versions**
-
-   Spack did not previously have a way to distinguish a version if it was a prefix of
-   some other version. For example, `@3.2` would match `3.2`, `3.2.1`, `3.2.2`, etc. You
-   can now match *exactly* `3.2` with `@=3.2`. This is useful, for example, if you need
-   to patch *only* the `3.2` version of a package. The new syntax is described in [the docs](
-     https://spack.readthedocs.io/en/latest/basic_usage.html#version-specifier).
-
-   Generally, when writing packages, you should prefer to use ranges like `@3.2` over
-   the specific versions, as this allows the concretizer more leeway when selecting
-   versions of dependencies. More details and recommendations are in the [packaging guide](
-     https://spack.readthedocs.io/en/latest/packaging_guide.html#ranges-versus-specific-versions).
-
-   See #36273 for full details on the version refactor.
-
-3. **New testing interface**
-
-   Writing package tests is now much simpler with a new [test interface](
-     https://spack.readthedocs.io/en/latest/packaging_guide.html#stand-alone-tests).
-
-   Writing a test is now as easy as adding a method that starts with `test_`:
-
-   ```python
-   class MyPackage(Package):
-       ...
-
-       def test_always_fails(self):
-           """use assert to always fail"""
-           assert False
-
-       def test_example(self):
-           """run installed example"""
-           example = which(self.prefix.bin.example)
-           example()
-    ```
-
-    You can use Python's native `assert` statement to implement your checks -- no more
-    need to fiddle with `run_test` or other test framework methods. Spack will
-    introspect the class and run `test_*` methods when you run `spack test`,
-
-4. **More stable concretization**
-
-   * Now, `spack concretize` will *only* concretize the new portions of the environment
-     and will not change existing parts of an environment unless you specify `--force`.
-     This has always been true for `unify:false`, but not for `unify:true` and
-     `unify:when_possible` environments. Now it is true for all of them (#37438, #37681).
-
-   * The concretizer has a new `--reuse-deps` argument that *only* reuses dependencies.
-     That is, it will always treat the *roots* of your environment as it would with
-     `--fresh`. This allows you to upgrade just the roots of your environment while
-     keeping everything else stable (#30990).
-
-5. **Weekly develop snapshot releases**
-
-   Since last year, we have maintained a buildcache of `develop` at
-   https://binaries.spack.io/develop, but the cache can grow to contain so many builds
-   as to be unwieldy. When we get a stable `develop` build, we snapshot the release and
-   add a corresponding tag the Spack repository. So, you can use a stack from a specific
-   day. There are now tags in the spack repository like:
-
-   * `develop-2023-05-14`
-   * `develop-2023-05-18`
-
-   that correspond to build caches like:
-
-   * https://binaries.spack.io/develop-2023-05-14/e4s
-   * https://binaries.spack.io/develop-2023-05-18/e4s
-
-   We plan to store these snapshot releases weekly.
-
-6. **Specs in buildcaches can be referenced by hash.**
-
-   * Previously, you could run `spack buildcache list` and see the hashes in
-     buildcaches, but referring to them by hash would fail.
-   * You can now run commands like `spack spec` and `spack install` and refer to
-     buildcache hashes directly, e.g. `spack install /abc123` (#35042)
-
-7. **New package and buildcache index websites**
-
-   Our public websites for searching packages have been completely revamped and updated.
-   You can check them out here:
-
-   * *Package Index*: https://packages.spack.io
-   * *Buildcache Index*: https://cache.spack.io
-
-   Both are searchable and more interactive than before. Currently major releases are
-   shown; UI for browsing `develop` snapshots is coming soon.
-
-8. **Default CMake and Meson build types are now Release**
-
-   Spack has historically defaulted to building with optimization and debugging, but
-   packages like `llvm` can be enormous with debug turned on. Our default build type for
-   all Spack packages is now `Release` (#36679, #37436). This has a number of benefits:
-
-   * much smaller binaries;
-   * higher default optimization level; and
-   * defining `NDEBUG` disables assertions, which may lead to further speedups.
-
-   You can still get the old behavior back through requirements and package preferences.
-
-## Other new commands and directives
-
-* `spack checksum` can automatically add new versions to package (#24532)
-* new command: `spack pkg grep` to easily search package files (#34388)
-* New `maintainers` directive (#35083)
-* Add `spack buildcache push` (alias to `buildcache create`) (#34861)
-* Allow using `-j` to control the parallelism of concretization (#37608)
-* Add `--exclude` option to 'spack external find' (#35013)
-
-## Other new features of note
-
-* editing: add higher-precedence `SPACK_EDITOR` environment variable
-* Many YAML formatting improvements from updating `ruamel.yaml` to the latest version
-  supporting Python 3.6. (#31091, #24885, #37008).
-* Requirements and preferences should not define (non-git) versions (#37687, #37747)
-* Environments now store spack version/commit in `spack.lock` (#32801)
-* User can specify the name of the `packages` subdirectory in repositories (#36643)
-* Add container images supporting RHEL alternatives (#36713)
-* make version(...) kwargs explicit (#36998)
-
-## Notable refactors
-
-* buildcache create: reproducible tarballs (#35623)
-* Bootstrap most of Spack dependencies using environments (#34029)
-* Split `satisfies(..., strict=True/False)` into two functions (#35681)
-* spack install: simplify behavior when inside environments (#35206)
-
-## Binary cache and stack updates
-
-* Major simplification of CI boilerplate in stacks (#34272, #36045)
-* Many improvements to our CI pipeline's reliability
-
-## Removals, Deprecations, and disablements
-* Module file generation is disabled by default; you'll need to enable it to use it (#37258)
-* Support for Python 2 was deprecated in `v0.19.0` and has been removed. `v0.20.0` only
-  supports Python 3.6 and higher.
-* Deprecated target names are no longer recognized by Spack. Use generic names instead:
-  * `graviton` is now `cortex_a72`
-  * `graviton2` is now `neoverse_n1`
-  * `graviton3` is now `neoverse_v1`
-* `blacklist` and `whitelist` in module configuration were deprecated in `v0.19.0` and are
-  removed in this release. Use `exclude` and `include` instead.
-* The `ignore=` parameter of the `extends()` directive has been removed. It was not used by
-  any builtin packages and is no longer needed to avoid conflicts in environment views (#35588).
-* Support for the old YAML buildcache format has been removed. It was deprecated in `v0.19.0` (#34347).
-* `spack find --bootstrap` has been removed. It was deprecated in `v0.19.0`. Use `spack
-  --bootstrap find` instead (#33964).
-* `spack bootstrap trust` and `spack bootstrap untrust` are now removed, having been
-  deprecated in `v0.19.0`. Use `spack bootstrap enable` and `spack bootstrap disable`.
-* The `--mirror-name`, `--mirror-url`, and `--directory` options to buildcache and
-  mirror commands were deprecated in `v0.19.0` and have now been removed. They have been
-  replaced by positional arguments (#37457).
-* Deprecate `env:` as top level environment key (#37424)
-* deprecate buildcache create --rel, buildcache install --allow-root (#37285)
-* Support for very old perl-like spec format strings (e.g., `$_$@$%@+$+$=`) has been
-  removed (#37425). This was deprecated in in `v0.15` (#10556).
-
-## Notable Bugfixes
-
-* bugfix: don't fetch package metadata for unknown concrete specs (#36990)
-* Improve package source code context display on error  (#37655)
-* Relax environment manifest filename requirements and lockfile identification criteria (#37413)
-* `installer.py`: drop build edges of installed packages by default (#36707)
-* Bugfix: package requirements with git commits (#35057, #36347)
-* Package requirements: allow single specs in requirement lists (#36258)
-* conditional variant values: allow boolean (#33939)
-* spack uninstall: follow run/link edges on --dependents (#34058)
-

-Using External GPU Support
-==========================
-
-Many packages come with a ``+cuda`` or ``+rocm`` variant. With no added
-configuration Spack will download and install the needed components.
-It may be preferable to use existing system support: the following sections
-help with using a system installation of GPU libraries.
-
------------------------------------
-Using an External ROCm Installation
------------------------------------
-
-Spack breaks down ROCm into many separate component packages. The following
-is an example ``packages.yaml`` that organizes a consistent set of ROCm
-components for use by dependent packages:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       compiler: [rocmcc@=5.3.0]
-       variants: amdgpu_target=gfx90a
-     hip:
-       buildable: false
-       externals:
-       - spec: hip@5.3.0
-         prefix: /opt/rocm-5.3.0/hip
-     hsa-rocr-dev:
-       buildable: false
-       externals:
-       - spec: hsa-rocr-dev@5.3.0
-         prefix: /opt/rocm-5.3.0/
-     llvm-amdgpu:
-       buildable: false
-       externals:
-       - spec: llvm-amdgpu@5.3.0
-         prefix: /opt/rocm-5.3.0/llvm/
-     comgr:
-       buildable: false
-       externals:
-       - spec: comgr@5.3.0
-         prefix: /opt/rocm-5.3.0/
-     hipsparse:
-       buildable: false
-       externals:
-       - spec: hipsparse@5.3.0
-         prefix: /opt/rocm-5.3.0/
-     hipblas:
-       buildable: false
-       externals:
-       - spec: hipblas@5.3.0
-         prefix: /opt/rocm-5.3.0/
-     rocblas:
-       buildable: false
-       externals:
-       - spec: rocblas@5.3.0
-         prefix: /opt/rocm-5.3.0/
-     rocprim:
-       buildable: false
-       externals:
-       - spec: rocprim@5.3.0
-         prefix: /opt/rocm-5.3.0/rocprim/
-
-This is in combination with the following compiler definition:
-
-.. code-block:: yaml
-
-   compilers:
-   - compiler:
-       spec: rocmcc@=5.3.0
-       paths:
-         cc: /opt/rocm-5.3.0/bin/amdclang
-         cxx: /opt/rocm-5.3.0/bin/amdclang++
-         f77: null
-         fc: /opt/rocm-5.3.0/bin/amdflang
-       operating_system: rhel8
-       target: x86_64
-
-This includes the following considerations:
-
-- Each of the listed externals specifies ``buildable: false`` to force Spack
-  to use only the externals we defined.
-- ``spack external find`` can automatically locate some of the ``hip``/``rocm``
-  packages, but not all of them, and furthermore not in a manner that
-  guarantees a complementary set if multiple ROCm installations are available.
-- The ``prefix`` is the same for several components, but note that others
-  require listing one of the subdirectories as a prefix.
-
------------------------------------
-Using an External CUDA Installation
------------------------------------
-
-CUDA is split into fewer components and is simpler to specify:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       variants:
-       - cuda_arch=70
-     cuda:
-       buildable: false
-       externals:
-       - spec: cuda@11.0.2
-         prefix: /opt/cuda/cuda-11.0.2/
-
-where ``/opt/cuda/cuda-11.0.2/lib/`` contains ``libcudart.so``.

-=====================
-Spack Package Signing
-=====================
-
-The goal of package signing in Spack is to provide data integrity
-assurances around official packages produced by the automated Spack CI
-pipelines. These assurances directly address the security of Spack’s
-software supply chain by explaining why a security-conscious user can
-be reasonably justified in the belief that packages installed via Spack
-have an uninterrupted auditable trail back to change management
-decisions judged to be appropriate by the Spack maintainers. This is
-achieved through cryptographic signing of packages built by Spack CI
-pipelines based on code that has been transparently reviewed and
-approved on GitHub. This document describes the signing process for
-interested users.
-
-.. _risks:
-
-------------------------------
-Risks, Impact and Threat Model
-------------------------------
-
-This document addresses the approach taken to safeguard Spack’s
-reputation with regard to the integrity of the package data produced by
-Spack’s CI pipelines. It does not address issues of data confidentiality
-(Spack is intended to be largely open source) or availability (efforts
-are described elsewhere). With that said the main reputational risk can
-be broadly categorized as a loss of faith in the data integrity due to a
-breach of the private key used to sign packages. Remediation of a
-private key breach would require republishing the public key with a
-revocation certificate, generating a new signing key, an assessment and
-potential rebuild/resigning of all packages since the key was breached,
-and finally direct intervention by every spack user to update their copy
-of Spack’s public keys used for local verification.
-
-The primary threat model used in mitigating the risks of these stated
-impacts is one of individual error not malicious intent or insider
-threat. The primary objective is to avoid the above impacts by making a
-private key breach nearly impossible due to oversight or configuration
-error. Obvious and straightforward measures are taken to mitigate issues
-of malicious interference in data integrity and insider threats but
-these attack vectors are not systematically addressed. It should be hard
-to exfiltrate the private key intentionally, and almost impossible to
-leak the key by accident.
-
-.. _overview:
-
------------------
-Pipeline Overview
------------------
-
-Spack pipelines build software through progressive stages where packages
-in later stages nominally depend on packages built in earlier stages.
-For both technical and design reasons these dependencies are not
-implemented through the default GitLab artifacts mechanism; instead
-built packages are uploaded to AWS S3 mirrors (buckets) where they are
-retrieved by subsequent stages in the pipeline. Two broad categories of
-pipelines exist: Pull Request (PR) pipelines and Develop/Release
-pipelines.
-
--  PR pipelines are launched in response to pull requests made by
-   trusted and untrusted users. Packages built on these pipelines upload
-   code to quarantined AWS S3 locations which cache the built packages
-   for the purposes of review and iteration on the changes proposed in
-   the pull request. Packages built on PR pipelines can come from
-   untrusted users so signing of these pipelines is not implemented.
-   Jobs in these pipelines are executed via normal GitLab runners both
-   within the AWS GitLab infrastructure and at affiliated institutions.
--  Develop and Release pipelines **sign** the packages they produce and carry
-   strong integrity assurances that trace back to auditable change management
-   decisions. These pipelines only run after members from a trusted group of
-   reviewers verify that the proposed changes in a pull request are appropriate.
-   Once the PR is merged, or a release is cut, a pipeline is run on protected
-   GitLab runners which provide access to the required signing keys within the
-   job. Intermediary keys are used to sign packages in each stage of the
-   pipeline as they are built and a final job officially signs each package
-   external to any specific packages’ build environment. An intermediate key
-   exists in the AWS infrastructure and for each affiliated instritution that
-   maintains protected runners. The runners that execute these pipelines
-   exclusively accept jobs from protected branches meaning the intermediate keys
-   are never exposed to unreviewed code and the official keys are never exposed
-   to any specific build environment.
-
-.. _key_architecture:
-
-----------------
-Key Architecture
-----------------
-
-Spack’s CI process uses public-key infrastructure (PKI) based on GNU Privacy
-Guard (gpg) keypairs to sign public releases of spack package metadata, also
-called specs. Two classes of GPG keys are involved in the process to reduce the
-impact of an individual private key compromise, these key classes are the
-*Intermediate CI Key* and *Reputational Key*. Each of these keys has signing
-sub-keys that are used exclusively for signing packages. This can be confusing
-so for the purpose of this explanation we’ll refer to Root and Signing keys.
-Each key has a private and a public component as well as one or more identities
-and zero or more signatures.
-
--------------------
-Intermediate CI Key
--------------------
-
-The Intermediate key class is used to sign and verify packages between stages
-within a develop or release pipeline. An intermediate key exists for the AWS
-infrastructure as well as each affiliated institution that maintains protected
-runners. These intermediate keys are made available to the GitLab execution
-environment building the package so that the package’s dependencies may be
-verified by the Signing Intermediate CI Public Key and the final package may be
-signed by the Signing Intermediate CI Private Key.

-
-
-The *Root intermediate CI Private Key*\ Is stripped out of the GPG key and
-stored offline completely separate from Spack’s infrastructure. This allows the
-core development team to append revocation certificates to the GPG key and
-issue new sub-keys for use in the pipeline. It is our expectation that this
-will happen on a semi regular basis. A corollary of this is that *this key
-should not be used to verify package integrity outside the internal CI process.*
-
-----------------
-Reputational Key
-----------------
-
-The Reputational Key is the public facing key used to sign complete groups of
-development and release packages. Only one key pair exsits in this class of
-keys. In contrast to the Intermediate CI Key the Reputational Key *should* be
-used to verify package integrity. At the end of develop and release pipeline a
-final pipeline job pulls down all signed package metadata built by the pipeline,
-verifies they were signed with an Intermediate CI Key, then strips the
-Intermediate CI Key signature from the package and re-signs them with the
-Signing Reputational Private Key. The officially signed packages are then
-uploaded back to the AWS S3 mirror. Please note that separating use of the
-reputational key into this final job is done to prevent leakage of the key in a
-spack package. Because the Signing Reputational Private Key is never exposed to
-a build job it cannot accidentally end up in any built package.

-The Root Reputational Private Key is stripped out of the GPG key and stored
-offline completely separate from Spack’s infrastructure. This allows the core
-development team to append revocation certificates to the GPG key in the

-.. _build_cache_format:
-
-------------------
-Build Cache Format
-------------------
-
-A binary package consists of a metadata file unambiguously defining the
-built package (and including other details such as how to relocate it)
-and the installation directory of the package stored as a compressed
-archive file. The metadata files can either be unsigned, in which case
-the contents are simply the json-serialized concrete spec plus metadata,
-or they can be signed, in which case the json-serialized concrete spec
-plus metadata is wrapped in a gpg cleartext signature. Built package
-metadata files are named to indicate the operating system and
-architecture for which the package was built as well as the compiler
-used to build it and the packages name and version. For example::
-
-  linux-ubuntu18.04-haswell-gcc-7.5.0-zlib-1.2.12-llv2ysfdxnppzjrt5ldybb5c52qbmoow.spec.json.sig
-
-would contain the concrete spec and binary metadata for a binary package
-of ``zlib@1.2.12``, built for the ``ubuntu`` operating system and ``haswell``
-architecture. The id of the built package exists in the name of the file
-as well (after the package name and version) and in this case begins
-with ``llv2ys``. The id distinguishes a particular built package from all
-other built packages with the same os/arch, compiler, name, and version.
-Below is an example of a signed binary package metadata file. Such a
-file would live in the ``build_cache`` directory of a binary mirror::

-The metadata (regardless whether signed or unsigned) contains the checksum
-of the ``.spack`` file containing the actual installation. The checksum should
-be compared to a checksum computed locally on the ``.spack`` file to ensure the

-``.spack`` files are actually tarballs containing the compressed archive of the
-install tree.  These files, along with the metadata files, live within the
-``build_cache`` directory of the mirror, and together are organized as follows::
-
-  build_cache/
-    # unsigned metadata (for indexing, contains sha256 of .spack file)
-    <arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
-    # clearsigned metadata (same as above, but signed)
-    <arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json.sig
-    <arch>/
-      <compiler>/

-          <arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spack
-
-Uncompressing and extracting the ``.spack`` file results in the install tree.
-This is in contrast to previous versions of spack, where the ``.spack`` file
-contained a (duplicated) metadata file, a signature file and a nested tarball
-containing the install tree.
-
-.. _internal_implementation:
-
------------------------
-Internal Implementation
------------------------
-
-The technical implementation of the pipeline signing process includes components
-defined in Amazon Web Services, the Kubernetes cluster, at affilicated
-institutions, and the GitLab/GitLab Runner deployment. We present the techincal
-implementation in two interdependent sections. The first addresses how secrets
-are managed through the lifecycle of a develop or release pipeline. The second
-section describes how Gitlab Runner and pipelines are configured and managed to
-support secure automated signing.
-
-Secrets Management
-^^^^^^^^^^^^^^^^^^
-
-As stated above the Root Private Keys (intermediate and reputational)
-are stripped from the GPG keys and stored outside Spack’s
-infrastructure.
-
-.. warning::
-  **TODO**
-    - Explanation here about where and how access is handled for these keys.
-    - Both Root private keys are protected with strong passwords
-    - Who has access to these and how?
-
-**Intermediate CI Key**
------------------------
-
-Multiple intermediate CI signing keys exist, one Intermediate CI Key for jobs
-run in AWS, and one key for each affiliated institution (e.g. Univerity of
-Oregon). Here we describe how the Intermediate CI Key is managed in AWS:
-
-The Intermediate CI Key (including the Signing Intermediate CI Private Key is
-exported as an ASCII armored file and stored in a Kubernetes secret called
-``spack-intermediate-ci-signing-key``. For convenience sake, this same secret
-contains an ASCII-armored export of just the *public* components of the
-Reputational Key. This secret also contains the *public* components of each of
-the affiliated institutions' Intermediate CI Key. These are potentially needed
-to verify dependent packages which may have been found in the public mirror or
-built by a protected job running on an affiliated institution's infrastrcuture
-in an earlier stage of the pipeline.
-
-Procedurally the ``spack-intermediate-ci-signing-key`` secret is used in
-the following way:
-
-1. A ``large-arm-prot`` or ``large-x86-prot`` protected runner picks up
-   a job tagged ``protected`` from a protected GitLab branch. (See
-   `Protected Runners and Reserved Tags <#_8bawjmgykv0b>`__).
-2. Based on its configuration, the runner creates a job Pod in the
-   pipeline namespace and mounts the spack-intermediate-ci-signing-key
-   Kubernetes secret into the build container
-3. The Intermediate CI Key, affiliated institutions' public key and the
-   Reputational Public Key are imported into a keyring by the ``spack gpg …``
-   sub-command. This is initiated by the job’s build script which is created by
-   the generate job at the beginning of the pipeline.
-4. Assuming the package has dependencies those specs are verified using
-   the keyring.
-5. The package is built and the spec.json is generated
-6. The spec.json is signed by the keyring and uploaded to the mirror’s
-   build cache.
-
-**Reputational Key**
---------------------
-
-Because of the increased impact to end users in the case of a private
-key breach, the Reputational Key is managed separately from the
-Intermediate CI Keys and has additional controls. First, the Reputational
-Key was generated outside of Spack’s infrastructure and has been signed
-by the core development team. The Reputational Key (along with the
-Signing Reputational Private Key) was then ASCII armor exported to a
-file. Unlike the Intermediate CI Key this exported file is not stored as
-a base64 encoded secret in Kubernetes. Instead\ *the key file
-itself*\ is encrypted and stored in Kubernetes as the
-``spack-signing-key-encrypted`` secret in the pipeline namespace.
-
-The encryption of the exported Reputational Key (including the Signing
-Reputational Private Key) is handled by `AWS Key Management Store (KMS) data
-keys
-<https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#data-keys>`__.
-The private key material is decrypted and imported at the time of signing into a
-memory mounted temporary directory holding the keychain. The signing job uses
-the `AWS Encryption SDK
-<https://docs.aws.amazon.com/encryption-sdk/latest/developer-guide/crypto-cli.html>`__
-(i.e. ``aws-encryption-cli``) to decrypt the Reputational Key. Permission to
-decrypt the key is granted to the job Pod through a Kubernetes service account
-specifically used for this, and only this, function. Finally, for convenience
-sake, this same secret contains an ASCII-armored export of the *public*
-components of the Intermediate CI Keys and the Reputational Key. This allows the
-signing script to verify that packages were built by the pipeline (both on AWS
-or at affiliated institutions), or signed previously as a part of a different
-pipeline. This is is done *before* importing decrypting and importing the
-Signing Reputational Private Key material and officially signing the packages.
-
-Procedurally the ``spack-singing-key-encrypted`` secret is used in the
-following way:
-
-1.  The ``spack-package-signing-gitlab-runner`` protected runner picks
-    up a job tagged ``notary`` from a protected GitLab branch (See
-    `Protected Runners and Reserved Tags <#_8bawjmgykv0b>`__).
-2.  Based on its configuration, the runner creates a job pod in the
-    pipeline namespace. The job is run in a stripped down purpose-built
-    image ``ghcr.io/spack/notary:latest`` Docker image. The runner is
-    configured to only allow running jobs with this image.
-3.  The runner also mounts the ``spack-signing-key-encrypted`` secret to
-    a path on disk. Note that this becomes several files on disk, the
-    public components of the Intermediate CI Keys, the public components
-    of the Reputational CI, and an AWS KMS encrypted file containing the
-    Singing Reputational Private Key.
-4.  In addition to the secret, the runner creates a tmpfs memory mounted
-    directory where the GnuPG keyring will be created to verify, and
-    then resign the package specs.
-5.  The job script syncs all spec.json.sig files from the build cache to
-    a working directory in the job’s execution environment.
-6.  The job script then runs the ``sign.sh`` script built into the
-    notary Docker image.
-7.  The ``sign.sh`` script imports the public components of the
-    Reputational and Intermediate CI Keys and uses them to verify good
-    signatures on the spec.json.sig files. If any signed spec does not
-    verify the job immediately fails.
-8.  Assuming all specs are verified, the ``sign.sh`` script then unpacks
-    the spec json data from the signed file in preparation for being
-    re-signed with the Reputational Key.
-9.  The private components of the Reputational Key are decrypted to
-    standard out using ``aws-encryption-cli`` directly into a ``gpg
-    –import …`` statement which imports the key into the
-    keyring mounted in-memory.
-10. The private key is then used to sign each of the json specs and the
-    keyring is removed from disk.
-11. The re-signed json specs are resynced to the AWS S3 Mirror and the
-    public signing of the packages for the develop or release pipeline
-    that created them is complete.
-
-Non service-account access to the private components of the Reputational
-Key that are managed through access to the symmetric secret in KMS used
-to encrypt the data key (which in turn is used to encrypt the GnuPG key
-- See:\ `Encryption SDK
-Documentation <https://docs.aws.amazon.com/encryption-sdk/latest/developer-guide/crypto-cli-examples.html#cli-example-encrypt-file>`__).
-A small trusted subset of the core development team are the only
-individuals with access to this symmetric key.
-
-.. _protected_runners:
-
-Protected Runners and Reserved Tags
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Spack has a large number of Gitlab Runners operating in its build farm.
-These include runners deployed in the AWS Kubernetes cluster as well as
-runners deployed at affiliated institutions. The majority of runners are
-shared runners that operate across projects in gitlab.spack.io. These
-runners pick up jobs primarily from the spack/spack project and execute
-them in PR pipelines.
-
-A small number of runners operating on AWS and at affiliated institutions are
-registered as specific *protected* runners on the spack/spack project. In
-addition to protected runners there are protected branches on the spack/spack
-project. These are the ``develop`` branch, any release branch (i.e. managed with
-the ``releases/v*`` wildcard) and any tag branch (managed with the ``v*``
-wildcard) Finally Spack’s pipeline generation code reserves certain tags to make
-sure jobs are routed to the correct runners, these tags are ``public``,
-``protected``, and ``notary``. Understanding how all this works together to
-protect secrets and provide integrity assurances can be a little confusing so
-lets break these down:
-
--  **Protected Branches**- Protected branches in Spack prevent anyone
-   other than Maintainers in GitLab from pushing code. In the case of
-   Spack the only Maintainer level entity pushing code to protected
-   branches is Spack bot. Protecting branches also marks them in such a
-   way that Protected Runners will only run jobs from those branches
-- **Protected Runners**- Protected Runners only run jobs from protected
-   branches. Because protected runners have access to secrets, it's critical
-   that they not run Jobs from untrusted code (i.e. PR branches). If they did it
-   would be possible for a PR branch to tag a job in such a way that a protected
-   runner executed that job and mounted secrets into a code execution
-   environment that had not been reviewed by Spack maintainers. Note however
-   that in the absence of tagging used to route jobs, public runners *could* run
-   jobs from protected branches. No secrets would be at risk of being breached
-   because non-protected runners do not have access to those secrets; lack of
-   secrets would, however, cause the jobs to fail.
-- **Reserved Tags**- To mitigate the issue of public runners picking up
-   protected jobs Spack uses a small set of “reserved” job tags (Note that these
-   are *job* tags not git tags). These tags are “public”, “private”, and
-   “notary.” The majority of jobs executed in Spack’s GitLab instance are
-   executed via a ``generate`` job. The generate job code systematically ensures
-   that no user defined configuration sets these tags. Instead, the ``generate``
-   job sets these tags based on rules related to the branch where this pipeline
-   originated. If the job is a part of a pipeline on a PR branch it sets the
-   ``public`` tag. If the job is part of a pipeline on a protected branch it
-   sets the ``protected`` tag. Finally if the job is the package signing job and
-   it is running on a pipeline that is part of a protected branch then it sets
-   the ``notary`` tag.
-
-Protected Runners are configured to only run jobs from protected branches. Only
-jobs running in pipelines on protected branches are tagged with ``protected`` or
-``notary`` tags. This tightly couples jobs on protected branches to protected
-runners that provide access to the secrets required to sign the built packages.
-The secrets are can **only** be accessed via:
-
-1. Runners under direct control of the core development team.
-2. Runners under direct control of trusted maintainers at affiliated institutions.
-3. By code running the automated pipeline that has been reviewed by the
-   Spack maintainers and judged to be appropriate.
-
-Other attempts (either through malicious intent or incompetence) can at
-worst grab jobs intended for protected runners which will cause those
-jobs to fail alerting both Spack maintainers and the core development
-team.

-   The Reputational Key has also cross signed core development team
-   keys.
