Reorganize the pipeline generation aspect of the ci module,
mostly to separate the representation, generation, and
pruning of pipeline graphs from platform-specific output
formatting.
Introduce a pipeline generation registry to support generating
pipelines for other platforms, though gitlab is still the only
supported format currently.
Fix a long-existing bug in pipeline pruning where only direct
dependencies were added to any nodes dependency list.
* Set the "build_jobs" on concretization/generate for CI
build_jobs also controls the concretization pool size. Set this
in the config section for CI generate.
This config is overwritten by build_job CI using the SPACK_BUILD_JOBS
environment variable. This implicitly will drop the default build
CPU request on all "default" grouped build jobs from (max) 16 to 8.
* Add default allocations for build jobs
* Add common jobs and concretize args to ci generate and rebuild
* CI: Specify parallel concretize and build jobs via argument
* Increase power and cray concretization limits
Lowering limits for these stacks creates timeout
`spack mirror add` and `set` now have flags `--oci-password-variable`, `--oci-password-variable`, `--s3-access-key-id-variable`, `--s3-access-key-secret-variable`, `--s3-access-token-variable`, which allows users to specify an environment variable in which a username or password is stored.
Storing plain text passwords in config files is considered deprecated.
The schema for mirrors.yaml has changed, notably the `access_pair` list is generally replaced with a dictionary of `{id: ..., secret_variable: ...}` or `{id_variable: ..., secret_variable: ...}`.
This PR adds a sub-command to `spack env` (`track`) which allows users to add/link
anonymous environments into their installation as named environments. This allows
users to more easily track their installed packages and the environments they're
dependencies of. For example, with the addition of #41731 it's now easier to remove
all packages not required by any environments with,
```
spack gc -bE
```
#### Usage
```
spack env track /path/to/env
==> Linked environment in /path/to/env
==> You can activate this environment with:
==> spack env activate env
```
By default `track /path/to/env` will use the last directory in the path as the name of
the environment. However users may customize the name of the linked environment
with `-n | --name`. Shown below.
```
spack env track /path/to/env --name foo
==> Tracking environment in /path/to/env
==> You can activate this environment with:
==> spack env activate foo
```
When removing a linked environment, Spack will remove the link to the environment
but will keep the structure of the environment within the directory. This will allow
users to remove a linked environment from their installation without deleting it from
a shared repository.
There is a `spack env untrack` command that can be used to *only* untrack a tracked
environment -- it will fail if it is used on a managed environment. Users can also use
`spack env remove` to untrack an environment.
This allows users to continue to share environments in git repositories while also having
the dependencies of those environments be remembered by Spack.

Currently, `spack solve` has different spec selection semantics than `spack spec`.
`spack solve` currently does not allow specifying a single spec when an environment is active.
This PR modifies `spack solve` to inherit the interface from `spack spec`, and to use
the same spec selection logic. This will allow for better use of `spack solve --show opt`
for debugging.

This PR is in response to a question in the `environments` slack channel (https://spackpm.slack.com/archives/CMHK7MF51/p1729200068557219) about inadequate CLI help/documentation for one specific subcommand.
This PR uses the approach I took for the descriptions and help for `spack test` subcommands. Namely, I use the first line of the relevant docstring as the description, which is shown per subcommand in `spack env -h`, and the entire docstring as the help. I then added, where it seemed appropriate, help. I also tweaked argument docstrings to tighten them up, make consistent with similar arguments elsewhere in the command, and elaborate when it seemed important. (The only subcommand I didn't touch is `loads`.)
For example, before:
```
$ spack env update -h
usage: spack env update [-hy] env
positional arguments:
env name or directory of the environment to activate
optional arguments:
-h, --help show this help message and exit
-y, --yes-to-all assume "yes" is the answer to every confirmation request
```
After the changes in this PR:
```
$ spack env update -h
usage: spack env update [-hy] env
update the environment manifest to the latest schema format
update the environment to the latest schema format, which may not be
readable by older versions of spack
a backup copy of the manifest is retained in case there is a need to revert
this operation
positional arguments:
env name or directory of the environment
optional arguments:
-h, --help show this help message and exit
-y, --yes-to-all assume "yes" is the answer to every confirmation request
```

ci: Remove deprecated logic from the ci module
Remove the following from the ci module, schema, and tests:
- deprecated ci stack and handling of old ci config
- deprecated mirror handling logic
- support for artifacts buildcache
- support for temporary storage url
`spack gc` has so far been a global or environment-specific thing.
This adds the ability to restrict garbage collection to specific specs,
e.g. if you *just* want to get rid of all your unused python installations,
you could write:
```console
spack gc python
```
- [x] add `constraint` arg to `spack gc`
- [x] add a simple test

"spack buildcache push" for partially installed environments pushes all it
can by default, and only dumps errors towards the end.
If --fail-fast is provided, error out before pushing anything if any
of the packages is uninstalled
oci build caches using parallel push now use futures to ensure pushing
goes in best-effort style.
`setup-env.sh` is meant to be sourced, not executed directly.
By revoking execution permissions, users who accidentally execute
the script will receive an error instead of seeing no effect.
* Remove execution permission from `setup-env.sh` and friends
* Don't make output file executable in `spack commands --update-completion`

Originally if you had `x -> y -> z`, and an env with `x` in its speclist that is concretized but not installed, then `spack find -c y` would not show anything. This was intended: `spack find` has up-until-now only ever listed out installed specs (and `-c` was for adding a preamble section about roots).
This changes `spack find` so:
* `-c` makes it search through all concretized specs in the env (in a sense it is anticipated that a concretized environment would serve as a "speculative" DB and users may want to query it like they query the DB outside of envs)
* Adds a `-i/--install-status` option, equivalent to `-I` from `spack spec`
* Shows install status for either `-c` or `-i`
* As a side effect to prior point, `spack find -i` can now distinguish different installation states (upstream/external)
Examples:
```
$ spack find -r
==> In environment findtest
==> 1 root specs
- raja
==> 6 installed packages (not shown)
==> 12 concretized packages to be installed (not shown)

Add the ability to include any number of (potentially nested) concrete environments, e.g.:
```yaml
spack:
specs: []
concretizer:
unify: true
include_concrete:
- /path/to/environment1
- /path/to/environment2
```
or, from the CLI:
```console
$ spack env create myenv
$ spack -e myenv add python
$ spack -e myenv concretize
$ spack env create --include-concrete myenv included_env
```
The contents of included concrete environments' spack.lock files are
included in the environment's lock file at creation time. Any changes
to included concrete environments are only reflected after the environment
is re-concretized from the re-concretized included environments.

Since reuse is the default now, `--reuse-deps` can be confusing, as it
technically does not imply roots are fresh.
So add `--fresh-roots`, which is also easier to discover when running
`spack concretize --fre<tab>`
Some packages can't be redistributed in source or binary form. We need an explicit way to say that in a package.
This adds a `redistribute()` directive so that package authors can write, e.g.:
```python
redistribute(source=False, binary=False)
```
You can also do this conditionally with `when=`, as with other directives, e.g.:
```python
# 12.0 and higher are proprietary
redistribute(source=False, binary=False, when="@12.0:")
# can't redistribute when we depend on some proprietary dependency
redistribute(source=False, binary=False, when="^proprietary-dependency")
```
To prevent Spack from adding either their sources or binaries to public mirrors and build caches. You can still unconditionally add things *if* you run either:
* `spack mirror create --private`
* `spack buildcache push --private`
But the default behavior for build caches is not to include non-redistributable packages in either mirrors or build caches. We have previously done this manually for our public buildcache, but with this we can start maintaining redistributability directly in packages.
Caveats: currently the default for `redistribute()` is `True` for both `source` and `binary`, and you can only set either of them to `False` via this directive.
- [x] add `redistribute()` directive
- [x] add `redistribute_source` and `redistribute_binary` class methods to `PackageBase`
- [x] add `--private` option to `spack mirror`
- [x] add `--private` option to `spack buildcache push`
- [x] test exclusion of packages from source mirror (both as a root and as a dependency)
- [x] test exclusion of packages from binary mirror (both as a root and as a dependency)
This adds some improvements to `spack find` output when in environments based
around some thoughts about what users want to know when they're in an env.
If you're working in an enviroment, you mostly care about:
* What are the roots
* Which ones are installed / not installed
* What's been added that still needs to be concretized
So, this PR adds a couple tweaks to display that information more clearly:
- [x] We now display install status next to every root. You can easily see
which are installed and which aren't.
- [x] When you run `spack find -l` in an env, the roots now show their concrete
hash (if they've been concretized). They previously would show `-------`
(b/c the root spec itself is abstract), but showing the concretized root's
hash is a lot more useful.
- [x] Newly added/unconcretized specs still show `-------`, which now makes more
sense, b/c they are not concretized.
- [x] There is a new option, `-r` / `--only-roots` to *only* show env roots if
you don't want to look at all the installed specs.
- [x] Roots in the installed spec list are now highlighted as bold. This is
actually an old feature from the first env implementation , but various
refactors had disabled it inadvertently.
This commit adds a property `autopush` to mirrors. When true, every source build is immediately followed by a push to the build cache. This is useful in ephemeral environments such as CI / containers.
To enable autopush on existing build caches, use `spack mirror set --autopush <name>`. The same flag can be used in `spack mirror add`.
Users requested an option to filter between local/upstream results in `spack find` output.
```
# default behavior, same as without --install-tree argument
$ spack find --install-tree all
# show only local results
$ spack find --install-tree local
# show results from all upstreams
$ spack find --install-tree upstream
# show results from a particular upstream or the local install_tree
$ spack find --install-tree /path/to/install/tree/root
```

Running a `spack-python` script like this:
```python
import spack
import multiprocessing
def echo(args):
print(args)
if __name__ == "__main__":
pool = multiprocessing.Pool(2)
pool.map(echo, range(10))
```
will fail in `develop` with an error like this:
```console
_pickle.PicklingError: Can't pickle <function echo at 0x104865820>: attribute lookup echo on __main__ failed
```
Python expects to be able to look up the method `echo` in `sys.path["__main__"]` in
subprocesses spawned by `multiprocessing`, but because we use `InteractiveConsole` to
run `spack python`, the executed file isn't considered to be the `__main__` module, and
lookups in subprocesses fail. We tried to fake this by setting `__name__` to `__main__`
in the `spack python` command, but that doesn't fix the fact that no `__main__` module
exists.
Another annoyance with `InteractiveConsole` is that `__file__` is not defined in the
main script scope, so you can't use it in your scripts.
We can use the [runpy.run_path()](https://docs.python.org/3/library/runpy.html#runpy.run_path) function,
which has been around since Python 3.2, to fix this.
- [x] Use `runpy` module to launch non-interactive `spack python` invocations
- [x] Only use `InteractiveConsole` for interactive `spack python`
Currently (outside of this PR) when you `spack develop` a path, this path is treated as the staging
directory (this means that for example all build artifacts are placed in the develop path).
This PR creates a separate staging directory for all `spack develop`ed builds. It looks like
```
# the stage root
/the-stage-root-for-all-spack-builds/
spack-stage-<hash>
# Spack packages inheriting CMakePackage put their build artifacts here
spack-build-<hash>/
```
Unlike non-develop builds, there is no `spack-src` directory, `source_path` is the provided `dev_path`.
Instead, separately, in the `dev_path`, we have:
```
/dev/path/for/foo/
build-{arch}-<hash> -> /the-stage-root-for-all-spack-builds/spack-stage-<hash>/
```
The main benefit of this is that build artifacts for out-of-source builds that are relative to
`Stage.path` are easily identified (and you can delete them with `spack clean`).
Other behavior added here:
- [x] A symlink is made from the `dev_path` to the stage directory. This symlink name incorporates
spec details, so that multiple Spack environments that develop the same path will not conflict
with one another
- [x] `spack cd` and `spack location` have added a `-c` shorthand for `--source-dir`
Spack builds can still change the develop path (in particular to keep track of applied patches),
and for in-source builds, this doesn't change much (although logs would not be written into
the develop path). Packages inheriting from `CMakePackage` should get this benefit
automatically though.
Like `spack change` for specs in environments, this can e.g. replace `examplespec+debug` with `examplespec~debug` in a `require:` section.
Example behavior for a config like:
```
packages:
foo:
require:
- spec: +debug
```
* `spack config change packages:foo:require:~debug` replaces `+debug` with `~debug`
* `spack config change packages:foo:require:@1.1` adds a requirement to the list
* `spack config change packages:bar:require:~debug` adds a requirement
Add `--create` option to `env activate` to allow users to create and activate in one command.

This adds options to `spack list` that allow you to list only packages from specific
repositories/namespaces, e.g.:
```console
spack list -r builtin
```
only lists packages from the `builtin` repo, while:
```console
spack list -r myrepo -r myrepo2
```
would list packages from `myrepo` and `myrepo2`, but not from `builtin`. Note that you
can use the same argument multiple times.
You can use either `-r` / `--repo` or `-N` / `--namespace`. `-N` is there to match the
corresponding option on `spack find`.
- [x] add `-r` / `--repo` / `-N` / `--namespace` argument
- [x] add test
This adds a few options to `spack gc`.
One to give you a little more control over dependencies:
* `-b` / `--keep-build-dependencies`: By default, `spack gc` considers build dependencies to be "no longer needed" once their dependents are installed. With this option, we'll keep build dependencies of needed installations as well.
And two more to make working with environments easier:
* `-E` / `--except-any-environment`: Garbage collect anything NOT needed by an environment. `spack gc -E` and `spack gc -bE` are now easy ways to get rid of everytihng not used by some environment.
* `-e` / `--except-environment` `ENV`: Instead of considering all environments, garbage collect everything not needed by a *specific* environment. Note that you can use this with `-E` to add directory environments to the list of considered envs, e.g.:
spack gc -E -e /path/to/direnv1 -e /path/to/direnv2 #...
- [x] rework `unused_specs()` method on DB to add options for roots and deptypes
- [x] add `all_hashes()` method on DB
- [x] rework `spack gc` command to add 3 more options
- [x] tests
This PR adds a flag `--tag/-t` to `buildcache push`, which you can use like
```
$ spack mirror add my-oci-registry oci://example.com/hello/world
$ spack -e my_env buildcache push --base-image ubuntu:22.04 --tag my_custom_tag my-oci-registry
```
and lets users ship a full, installed environment as a minimal container image where each image layer is one Spack package, on top of a base image of choice. The image can then be used as
```
$ docker run -it --rm example.com/hello/world:my_custom_tag
```
Apart from environments, users can also pick arbitrary installed spec from their database, for instance:
```
$ spack buildcache push --base-image ubuntu:22.04 --tag some_specs my-oci-registry gcc@12 cmake
$ docker run -it --rm example.com/hello/world:some_specs
```
It has many advantages over `spack containerize`:
1. No external tools required (`docker`, `buildah`, ...)
2. Creates images from locally installed Spack packages (No need to rebuild inside `docker build`, where troubleshooting build failures is notoriously hard)
3. No need for multistage builds (Spack just tarballs existing installations of runtime deps)
4. Reduced storage size / composability: when pushing multiple environments with common specs, container image layers are shared.
5. Automatic build cache: later `spack install` of the env elsewhere speeds up since the containerized environment is a build cache
* add trim function to `Spec` and `--ignore` option to 'spack diff'
Allows user to compare two specs while ignoring the sub-DAG of a particular dependency, e.g.
spack diff --ignore=mpi --ignore=zlib trilinos/abcdef trilinos/fedcba
to focus on differences closer to the root of the software stack
* Add `signed` property to mirror config
* make unsigned a tri-state: true/false overrides mirror config, none takes mirror config
* test commands
* Document this
* add a test
We have two ways to concretize now:
* `spack concretize` concretizes only the root specs that are not concrete in the environment.
* `spack concretize -f` eliminates all cached concretization data and reconcretizes the *entire* environment.
This PR adds `spack deconcretize`, which eliminates cached concretization data for a spec. This allows
users greater control over what is preserved from their `spack.lock` file and what is reused when not
using `spack concretize -f`. If you want to update a spec installed in your environment, you can call
`spack deconcretize` on it, and that spec and any relevant dependents will be removed from the lock file.
`spack concretize` has two options:
* `--root`: limits deconcretized specs to *specific* roots in the environment. You can use this to
deconcretize exactly one root in a `unify: false` environment. i.e., if `foo` root is a dependent
of `bar`, both roots, `spack deconcretize bar` will *not* deconcretize `foo`.
* `--all`: deconcretize *all* specs that match the input spec. By default `spack deconcretize`
will complain about multiple matches, like `spack uninstall`.
This changes variant display to use a much more legible format, and to use screen space
much better (particularly on narrow terminals). It also adds color the variant display
to match other parts of `spack info`.
Descriptions and variant value lists that were frequently squished into a tiny column
before now have closer to the full terminal width.
This change also preserves any whitespace formatting present in `package.py`, so package
maintainers can make easer-to-read descriptions of variant values if they want. For
example, `gasnet` has had a nice description of the `conduits` variant for a while, but
it was wrapped and made illegible by `spack info`. That is now fixed and the original
newlines are kept.
Conditional variants are grouped by their when clauses by default, but if you do not
like the grouping, you can display all the variants in order with `--variants-by-name`.
I'm not sure when people will prefer this, but it makes it easier to tell that a
particular variant is/isn't there. I do think grouping by `when` is the better default.
Currently there's some hacky logic in the AppleClang compiler that makes
it also accept `gfortran` as a fortran compiler if `flang` is not found.
This is guarded by `if sys.platform` checks s.t. it only applies to
Darwin.
But on Linux the feature of detecting mixed toolchains is highly
requested too, cause it's rather annoying to run into a failed build of
`openblas` after dozens of minutes of compiling its dependencies, just
because clang doesn't have a fortran compiler.
In particular in CI where the system compilers may change during system
updates, it's typically impossible to fix compilers in a hand-written
compilers.yaml config file: the config will almost certainly be outdated
sooner or later, and maintaining one config file per target machine and
writing logic to select the correct config is rather undesirable too.
---
This PR introduces a flag `spack compiler find --mixed-toolchain` that
fills out missing `fc` and `f77` entries in `clang` / `apple-clang` by
picking the best matching `gcc`.
It is enabled by default on macOS, but not on Linux, matching current
behavior of `spack compiler find`.
The "best matching gcc" logic and compiler path updates are identical to
how compiler path dictionaries are currently flattened "horizontally"
(per compiler id). This just adds logic to do the same "vertically"
(across different compiler ids).
So, with this change on Ubuntu 22.04:
```
$ spack compiler find --mixed-toolchain
==> Added 6 new compilers to /home/harmen/.spack/linux/compilers.yaml
gcc@13.1.0 gcc@12.3.0 gcc@11.4.0 gcc@10.5.0 clang@16.0.0 clang@15.0.7
==> Compilers are defined in the following files:
/home/harmen/.spack/linux/compilers.yaml
```
you finally get:
```
compilers:
- compiler:
spec: clang@=15.0.7
paths:
cc: /usr/bin/clang
cxx: /usr/bin/clang++
f77: /usr/bin/gfortran
fc: /usr/bin/gfortran
flags: {}
operating_system: ubuntu23.04
target: x86_64
modules: []
environment: {}
extra_rpaths: []
- compiler:
spec: clang@=16.0.0
paths:
cc: /usr/bin/clang-16
cxx: /usr/bin/clang++-16
f77: /usr/bin/gfortran
fc: /usr/bin/gfortran
flags: {}
operating_system: ubuntu23.04
target: x86_64
modules: []
environment: {}
extra_rpaths: []
```
The "best gcc" is automatically default system gcc, since it has no
suffixes / prefixes.
This completes to `spack concretize`:
```
spack conc<tab>
```
but this still gets hung up on the difference between `concretize` and `concretise`:
```
spack -e . conc<tab>
```
We were checking `"$COMP_CWORD" = 1`, which tracks the word on the command line
including any flags and their args, but we should track `"$COMP_CWORD_NO_FLAGS" = 1` to
figure out if the arg we're completing is the first real command.
Credits to @ChristianKniep for advocating the idea of OCI image layers
being identical to spack buildcache tarballs.
With this you can configure an OCI registry as a buildcache:
```console
$ spack mirror add my_registry oci://user/image # Dockerhub
$ spack mirror add my_registry oci://ghcr.io/haampie/spack-test # GHCR
$ spack mirror set --push --oci-username ... --oci-password ... my_registry # set login credentials
```
which should result in this config:
```yaml
mirrors:
my_registry:
url: oci://ghcr.io/haampie/spack-test
push:
access_pair: [<username>, <password>]
```
It can be used like any other registry
```
spack buildcache push my_registry [specs...]
```
It will upload the Spack tarballs in parallel, as well as manifest + config
files s.t. the binaries are compatible with `docker pull` or `skopeo copy`.
In fact, a base image can be added to get a _runnable_ image:
```console
$ spack buildcache push --base-image ubuntu:23.04 my_registry python
Pushed ... as [image]:python-3.11.2-65txfcpqbmpawclvtasuog4yzmxwaoia.spack
$ docker run --rm -it [image]:python-3.11.2-65txfcpqbmpawclvtasuog4yzmxwaoia.spack
```
which should really be a game changer for sharing binaries.
Further, all content-addressable blobs that are downloaded and verified
will be cached in Spack's download cache. This should make repeated
`push` commands faster, as well as `push` followed by a separate
`update-index` command.

- [x] #39341
- [x] Not a blocker: #35737 fixes correctness run env for the generated container images
NOTE:
1. `oci://` is unfortunately taken, so it's being abused in this PR to mean "oci type mirror". `skopeo` uses `docker://` which I'd like to avoid, given that classical docker v1 registries are not supported.
2. this is currently `https`-only, given that basic auth is used to login. I _could_ be convinced to allow http, but I'd prefer not to, given that for a `spack buildcache push` command multiple domains can be involved (auth server, source of base image, destination registry). Right now, no urllib http handler is added, so redirects to https and auth servers with http urls will simply result in a hard failure.
CAVEATS:
1. Signing is not implemented in this PR. `gpg --clearsign` is not the nicest solution, since (a) the spec.json is merged into the image config, which must be valid json, and (b) it would be better to sign the manifest (referencing both config/spec file and tarball) using more conventional image signing tools
2. `spack.binary_distribution.push` is not yet implemented for the OCI buildcache, only `spack buildcache push` is. This is because I'd like to always push images + deps to the registry, so that it's `docker pull`-able, whereas in `spack ci` we really wanna push an individual package without its deps to say `pr-xyz`, while its deps reside in some `develop` buildcache.
3. The `push -j ...` flag only works for OCI buildcache, not for others
Currently `spack env activate --with-view` exists, but is a no-op.
So, it is not too much of a breaking change to make this redundant flag
accept a value `spack env activate --with-view <name>` which activates
a particular view by name.
The view name is stored in `SPACK_ENV_VIEW`.
This also fixes an issue where deactivating a view that was activated
with `--without-view` possibly removes entries from PATH, since now we
keep track of whether the default view was "enabled" or not.
This PR adds a new audit sub-command to check that detection of relevant packages
is performed correctly in a few scenarios mocking real use-cases. The data for each
package being tested is in a YAML file called detection_test.yaml alongside the
corresponding package.py file.
This is to allow encoding detection tests for compilers and other widely used tools,
in preparation for compilers as dependencies.
