* filesystem: use lstat in recursive mtime
When a `develop` path contains a dead symlink, the `os.stat` in the recursive `mtime` determination trips up over it.
Closes#32165.
`requirement_policy/3` is generated and may not be in Spack's inputs to Clingo.
Currently this is causing warnings like:

- [x] Silence warning with `#defined requirement_policy/3`
Spack doesn't have an easy way to say something like "If I build
package X, then I *need* version Y":
* If you specify something on the command line, then you ensure
that the constraints are applied, but the package is always built
* Likewise if you `spack add X...`` to your environment, the
constraints are guaranteed to hold, but the environment always
builds the package
* You can add preferences to packages.yaml, but these are not
guaranteed to hold (Spack can choose other settings)
This commit adds a 'require' subsection to packages.yaml: the
specs added there are guaranteed to hold. The commit includes
documentation for the feature.

All PRs are failing the docs build on account of an error with
pygments. These errors coincide with a new release of pygments
(2.13.0) and restricting to < 2.13 allows the doc tests to pass,
so this commit enforces that constraint for the docs build.

This PR fixes the performance regression reported in #31985 and a few
other issues found while refactoring the spack mirror create command.
Modifications:
* (Primary) Do not require concretization for
`spack mirror create --all`
* Forbid using --versions-per-spec together with --all
* Fixed a few issues when reading specs from input file (specs were
not concretized, command would fail when trying to mirror
dependencies)
* Fix issue with default directory for spack mirror create not being
canonicalized
* Add more unit tests to poke spack mirror create
* Skip externals also when mirroring environments
* Changed slightly the wording for reporting (it was mentioning
"Successfully created" even in presence of errors)
* Fix issue with colify (was not called properly during error
reporting)
`LD_LIBRARY_PATH` can break system executables (e.g., when an enviornment is loaded) and isn't necessary thanks to `RPATH`s. Packages that require `LD_LIBRARY_PATH` can set this in `setup_run_environment`.
- [x] Prefix inspections no longer set `LD_LIBRARY_PATH` by default
- [x] Document changes and workarounds for people who want `LD_LIBRARY_PATH`
These changes make many packages build on nixos where nearly nothing
comes from /bin or /usr/bin (the only things in "system locations" are
/bin/sh and /usr/bin/env, all the rest is found through PATH).
Many configuration scripts hardcode /usr/bin/file instead of using the
one from PATH. This patches them to use file from PATH.

The current use of git ref's as a version requires a search algorithm to pick the right matching version based on the tags in the git history of the package.
This is less than ideal for the use case where users already know the specific version they want the git ref to be associated with. This PR makes a new version syntax [package]@[ref]=[version] to allow the users to specify the exact hash they wish to use.
On some systems the shell in login mode wipes important parts of the
environment, such as PATH. This causes the build to fail since it can't
find `spack`.
For better robustness, don't use a login shell.
In a full CI job the final spack install is run in an environment formed by scripts running in this order:
export AWS_SECRET=... # 1. Load environment from GitLab project variables
source spack/share/spack/setup-env.sh # 2. Load Spack into the environment (PATH)
spack env activate -V concrete_env # 3. Activate the concrete environment
source /etc/profile # 4. Bash login shell (from -l)
spack install ...
Whereas when a user launches their own container with (docker|podman) run -it, they end up running spack install in an environment formed in this order:
source /etc/bash.bashrc # (not 4). Bash interactive shell (default with TTY)
export AWS_SECRET=... #~1. Manually load environment from GitLab project variables
source spack/share/spack/setup-env.sh # 2. Load Spack into the environment (PATH)
spack env activate -V concrete_env # 3. Activate the concrete environment
spack install ...
The big problem being that (4) has a completely different position and content (on Leap 15 and possibly other containers).
So in context, this PR removes (4) from the CI job case, leaving us with the simpler:
export AWS_SECRET=... # 1. Load environment from GitLab project variables
source spack/share/spack/setup-env.sh # 2. Load Spack into the environment (PATH)
spack env activate -V concrete_env # 3. Activate the concrete environment
spack install ...
* database: don't sort on return from query_local
* ASP-based solver: don't build the hash-lookup dictionary twice
Building this dictionary twice and traversing all the specs
might be time-consuming for large buildcaches.
This test relied on an old version of the `flake8_package` fixture that modified
the spack repository, but it doesn't do that anymore. There are other tests for
`changed_files()` that do a better job of mocking up a git repository with
changes, so we can just delete this one.
`spack style` tests were annoyingly brittle because we could not easily be
specific about which tools to run (we had to use `--no-black`, `--no-isort`,
`--no-flake8`, and `--no-mypy`). We should be able to specify what to run OR
what to skip.
Now you can run, e.g.:
spack style --tool black,flake8
or:
spack style --skip black,isort
- [x] Remove `--no-black`, `--no-isort`, `--no-flake8`, and `--no-mypy` args.
- [x] Add `--tool TOOL` argument.
- [x] Add `--skip TOOL` argument.
- [x] Allow either `--tool black --tool flake8` or `--tool black,flake8` syntax.
- [x] remove alignment spaces from tempaltes
- [x] replace single with double quotes
- [x] Makefile template now generates parsable code
(function body is `pass` instead of just a comment)
- [x] template checks now run black to check output
Previously we'd accept any version for bootstrapping black, but we need <= 21.
- [x] modify bootstrapping code to check black version before accepting an
executable from `PATH`.
- [x] add `.git-blame-ignore-revs` to ignore black reformatting
- [x] make `spack blame` respect `.git-blame-ignore-revs`
(even if the user hasn't configured git to do so)
Some of our tests rely on single vs. double quotes, and others rely on specific
line numbers in the source. These needed fixing after the switch to Black.
Black will automatically fix a lot of the exceptions we previously allowed for
directives, so we don't need them in our custom `flake8_formatter` anymore.
- [x] remove `E501` (long line) exceptions for directives from `flake8_formatter`,
as they won't help us now.
- [x] Refine exceptions for long URLs in the `flake8_formatter`.
- [x] Adjust the mock `flake8-package` to exhibit the exceptions we still allow.
- [x] Update style tests for new `flake8-package`.
- [x] Blacken style test.
Many noqa's in the code are no longer necessary now that the column limit is 99
characters. Others can easily be eliminated, and still more can just be made more
specific if they do not have to do with line length.
The only E501's still in the code are in the tests for `spack.util.path` and the tests
for `spack style`.
This adds necessary configuration for flake8 and black to work together.
This also sets the line length to 99, per the data here:
* https://github.com/spack/spack/pull/24718#issuecomment-876933636
Given the data and the spirit of black's 88-character limit, we set the limit to 99
characters for all of Spack, because:
* 99 is one less than 100, a nice round number, and all lines will fit in a
100-character wide terminal (even when the text editor puts a \ at EOL).
* 99 is just past the knee the file size curve for packages, and it means that packages
remain readable and not significantly longer than they are now.
* It doesn't seem to hurt core -- files in core might change length by a few percent but
seem like they'll be mostly the same as before -- just a bit more roomy.
- [x] set line length to 99
- [x] remove most exceptions from `.flake8` and add the ones black cares about
- [x] add `[tool.black]` to `pyproject.toml`
- [x] make `black` run if available in `spack style --fix`

In #31618 the idea was to determine the file extension heuristically by dropping query params etc from a url and then consider it as a file path. That broke for URLs that only have query params like http://example.com/?patch=x as it would result in empty string as basename. This PR reverts to the old behavior of saving files as ?patch=x in that case.

`self.archive_file` is (among others) a symlink to a tarball. `extension()` on a

When
1. Spack installs libtool,
2. system libtool is installed too, and
3. system automake is used
Spack passes system automake's `-I <prefix>` flag to itself, even though
it's a default search path. This takes precedence over spack's libtool
prefix dir. This causes the wrong `libtool.m4` file to be used (since
system libtool is in the same prefix as system automake).
And that leads to error messages about incompatible libtool, something
something LT_INIT.
fixes#31627
spack.mirror.get_all_versions now uses the package class
instead of the package object in its implementation.
Ensure spec is concrete before staging for mirrors
Newer versions of botocore (>=1.23.47) support the full IOBase
interface, so the hacks added to supplement the missing attributes are
no longer needed. Conditionally disable the hacks if they appear to be
unnecessary based on the class hierarchy found at runtime.
* Add connection information to buildcache update command
Ensure that the s3 connection made when attempting to update the content
of a buildcache attempts to use the extra connection information
from the mirror creation.
* Add unique help for endpoint URL argument
Fix copy/paste error for endpoint URL help which was the same as
the access token
* Re-work URL checking for S3 mirrors
Due to the fact that nested bucket URLs would never match the string used
for checking that the mirror is the same, switch the check used.
Sort all mirror URLs by length to have the most specific cases first
and see if the desired URL "starts with" the mirror URL.
* Long line style fixes
Add execptions for long lines and fix other style errors
* Use format() function to rebuild URL
Use the format command to rebuild the url instead of crafing a
formatted string out of known values
* Add early exit for URL checking
When a valid mirror is found, break from the loop
For a long time the module configuration has had a few settings that use
`blacklist`/`whitelist` terminology. We've been asked by some of our users to replace
this with more inclusive language. In addition to being non-inclusive, `blacklist` and
`whitelist` are inconsistent with the rest of Spack, which uses `include` and `exclude`
for the same concepts.
- [x] Deprecate `blacklist`, `whitelist`, `blacklist_implicits` and `environment_blacklist`
in favor of `exclude`, `include`, `exclude_implicits` and `exclude_env_vars` in module
configuration, to be removed in Spack v0.20.
- [x] Print deprecation warnings if any of the deprecated names are in module config.
- [x] Update tests to test old and new names.
- [x] Update docs.
- [x] Update `spack config update` to fix this automatically, and include a note in the error
that you can use this command.
Python's built-in tarfile support doesn't address some general
cases of malformed tarfiles that are already handled by the system
'tar' utility; until these can be addressed, use that exclusively.
The goal of this PR is to make clearer where we need a package object in Spack as opposed to a package class.
We currently instantiate a lot of package objects when we could make do with a class. We should use the class
when we only need metadata, and we should only instantiate and us an instance of `PackageBase` at build time.
Modifications:
- [x] Remove the `spack.repo.get` convenience function (which was used in many places, and not really needed)
- [x] Use `spack.repo.path.get_pkg_class` wherever possible
- [x] Try to route most of the need for `spack.repo.path.get` through `Spec.package`
- [x] Introduce a non-data descriptor, that can be used as a decorator, to have "class level properties"
- [x] Refactor unit tests that had to be modified to reduce code duplication
- [x] `Spec.package` and `Repo.get` now require a concrete spec as input
- [x] Remove `RepoPath.all_packages` and `Repo.all_packages`
There's a race condition in `remove()` as the lockfile is removed after
releasing the lock, which is a problem when another process acquires a
write lock during deletion.
Also simplify life a bit in multiprocessing when a file is possibly
removed multiple times, which currently is an error on the second
deletion, so the proposed fix is to make remove(...) idempotent and not
error when deleting non-existing cache entries.
Don't tests for existence of lockfile, cause windows/linux behavior is different
Oversight in #31433, the non-phony `env` target was missing a file being
created for it, which can cause make to infinitely loop when including
multiple generated makefiles.
When no default editor is installed and no environment variable is set,
which_string would return None and this would be passed to os.execv
resulting in a TypeError. The message presented to the user would be:
Error: execv: path should be string, bytes or os.PathLike,
not NoneType
This change checks that which_string has returned successfully before
attempting to execute the result, resulting in a new error message:
Error: No text editor found! Please set the VISUAL and/or EDITOR
environment variable(s) to your preferred text editor.
It's not strictly necessary, but I've also changed try_exec to catch
all errors rather than just OSErrors. This would have provided slightly
more context for the original error message.
There were two choices: 1) remove '-p' from '-a' or 2) allow monkeypatching
the cleaning of the python cache since clean's test_function_calls isn't
supposed to be actually cleaning anything.
This commit supports the latter and adds a test case for `-p`.
Release branches and tags run protected pipelines, and we noticed
that those pipelines were generating all jobs in the stack, even
when the mirror contained all the built specs and an up to date
index. The problem was caused because the override mirror was
not present in spacks mirror configuration at the time when the
binary_distribution.update() method was called. This fixes that
by always adding the mirror override, if present, to the list of
configured mirrors.
* remove unhelpful comment
* Filter compiler duplicates while reading manifest

Building on #24639, this allows versions to be prefixed by `git.`. If a version begins `git.`, it is treated as a git ref, and handled as git commits are starting in the referenced PR.
An exception is made for versions that are `git.develop`, `git.main`, `git.master`, `git.head`, or `git.trunk`. Those are assumed to be greater than all other versions, as those prefixed strings are in other contexts.
This commit adds some changes which improve use of Spack-installed
oneAPI packages with Spack-generated modules, but not within Spack
(e.g. if you install some of these packages with Spack, then load
their associated modules to build other packages outside of Spack).
The majority of the PR diff is refactoring. The functional changes
are:
* intel-oneapi-mkl:
* setup_run_environment: update Intel compiler flags to RPATH the
mkl libs
* intel-oneapi-compilers: update the compiler configuration to RPATH
libraries installed by this package (note that Spack already handled
this when installing dependent packages with Spack, but this is
specifically to use the intel-oneapi-compilers package outside
of Spack). Specifically:
* inject_rpaths: this modifies the binaries installed as part of
the intel-oneapi-compilers package to RPATH libraries provided
by this package
* extend_config_flags: this instructs the compiler executables
provided by this package to RPATH those same libraries
Refactoring includes:
* intel-oneapi-compilers: in addition to the functional changes,
a large portion of this diff is reorganizing the creation of
resources/archives downloaded for the install
* The base oneAPI package renamed component_path, so several packages
changed as a result:
* intel-oneapi-dpl
* intel-oneapi-dnn
* extrae
* intel-oneapi-mpi:
* Perform file filtering in one pass rather than two
Allow `spack external find` (with no extra args) to proceed if the manifest file exists but
without sufficient permissions; in that case, print a warning. Also add a test for that behavior.
TODOs:
- [x] continue past any exception raised during manifest parsing as part of `spack external find`,
except for CTRL-C (and other errors that indicate immediate program termination)
- [x] Semi-unrelated but came up when discussing this with the user who reported this issue to
me: the manifest parser now accepts older schemas

Instead of giving a penalty of 30 to all nodes when preferences
are not package specific, give a penalty of 100 to all targets
of a node where we have package specific preferences, if the target
is not explicitly preferred.
* Fixed a bug in the 'external find --all' command where the call failed
to find packages by both executable and library. The bug was that the
call `path.all_packages()` incorrectly turned the variable
`packages_to_check` into a generator rather than keeping it a list.
Thus the second call to `detection.by_library` had no work to do.
* Fixed the help message for the find external and compiler commands as
well as others that used the `scopes_metavar` field to define where
the results should be stored in configuration space. Specifically,
the fact that configuration could be added to the environment was not
mentioned in the help message.
* add test to verify fix works
* fix spec cflags/variants parsing test (breaking change)
* fix `spack spec` arg quoting issue
* add error report for deprecated cflags coalescing
* use .group(n) vs subscript regex group extraction for 3.5 compat
* add random test for untested functionality to pass codecov
* fix new test failure since rebase
Fix a bug introduced in #21720. `spack_json.dump()` calls `_strify()` on dictionaries to
convert `unicode` to `str`, but it constructs `dict` objects instead of
`collections.OrderedDict` objects, so in Python 2 (or earlier versions of 3) it can
scramble dictionary order.
This can cause hashes to differ between Python 2 and Python 3, or between Python 3.7
and earlier Python 3's.
- [x] use `OrderedDict` in `_strify`
- [x] add a regression test
The "submodules" argument of the "version" directive can now accept
a callable that returns a list of submodules, in addition to the usual
Boolean values
* bootstrap: account for disabled sources
Fix a bug introduced in #30192, which effectively skips
any prescription on disabled bootstrapping sources.
* Add unit test to avoid regression
Fixes#31021
With #25185, we no longer default to using tar when we can't
determine the extension type, opting to fail instead.
This broke fetching for the pcre package, where we couldn't determine
the extension. To determine the extension, we were attempting to
extract it from the destination filename; however, this file name
may omit details of the origin URL that are required to determine the
extension, so instead we examine the URL directly.
This also updates the decompressor_for method not to set ext=None
by default: it must now always be set by the caller.
Most package installations include compressed source files. This
adds support for common archive types on Windows:
* Add support for using system 7zip functionality to decompress .Z
files when available (and on Windows, use 7zip for .xz archives)
* Default to using built-in Python support for tar/bz2 decompression
(note that Python tar documentation mentions preservation of file
permissions)
* Add tests for decompression support
* Extract logic for handling exploding archives (i.e. compressed
archives that expand to more than one base file) into an
exploding_archive_catch context manager in the filesystem module
Spack's staging logic constructs a file path based on a URL. The URL
may contain characters which are not allowed in valid file paths on
the system (e.g. Windows prohibits ':' and '?' among others). This
commit adds a function to remove such offending characters (but
otherwise preserves the URL string when constructing a file path).
Updates to improve Spack-generated modules for Intel oneAPI compilers:
* intel-oneapi-compilers set CC etc.
* Add a new package intel-oneapi-compilers-classic which can be used to
generate a module which sets CC etc. to older compilers (e.g. icc)
* lmod module logic now updated to treat the intel-oneapi-compilers*
packages as compilers
Explicitly import package utilities in all packages, and corresponding fallout.
This includes:
* rename `spack.package` to `spack.package_base`
* rename `spack.pkgkit` to `spack.package`
* update all packages in builtin, builtin_mock and tutorials to include `from spack.package import *`
* update spack style
* ensure packages include the import
* automatically add the new import and remove any/all imports of `spack` and `spack.pkgkit`
from packages when using `--fix`
* add support for type-checking packages with mypy when SPACK_MYPY_CHECK_PACKAGES
is set in the environment
* fix all type checking errors in packages in spack upstream
* update spack create to include the new imports
* update spack repo to inject the new import, injection persists to allow for a deprecation period
Original message below:
As requested @adamjstewart, update all packages to use pkgkit. I ended up using isort to do this,
so repro is easy:
```console
$ isort -a 'from spack.pkgkit import *' --rm 'spack' ./var/spack/repos/builtin/packages/*/package.py
$ spack style --fix
```
There were several line spacing fixups caused either by space manipulation in isort or by packages
that haven't been touched since we added requirements, but there are no functional changes in here.
* [x] add config to isort to make sure this is maintained going forward
referred targets are currently the only minimization criteria for Spack for which we allow
negative values. That means Spack may be incentivized to add nodes to the DAG if they
match the preferred target.
This PR re-norms the minimization criteria so that preferred targets are weighted from 0,
and default target weights are offset by the number of preferred targets per-package to
calculate node_target_weight.
Also fixes a bug in the test for preferred targets that was making the test easier to pass
than it should be.
This PR supports the creation of securely signed binaries built from spack
develop as well as release branches and tags. Specifically:
- remove internal pr mirror url generation logic in favor of buildcache destination
on command line
- with a single mirror url specified in the spack.yaml, this makes it clearer where
binaries from various pipelines are pushed
- designate some tags as reserved: ['public', 'protected', 'notary']
- these tags are stripped from all jobs by default and provisioned internally
based on pipeline type
- update gitlab ci yaml to include pipelines on more protected branches than just
develop (so include releases and tags)
- binaries from all protected pipelines are pushed into mirrors including the
branch name so releases, tags, and develop binaries are kept separate
- update rebuild jobs running on protected pipelines to run on special runners
provisioned with an intermediate signing key
- protected rebuild jobs no longer use "SPACK_SIGNING_KEY" env var to
obtain signing key (in fact, final signing key is nowhere available to rebuild jobs)
- these intermediate signatures are verified at the end of each pipeline by a new
signing job to ensure binaries were produced by a protected pipeline
- optionallly schedule a signing/notary job at the end of the pipeline to sign all
packges in the mirror
- add signing-job-attributes to gitlab-ci section of spack environment to allow
configuration
- signing job runs on special runner (separate from protected rebuild runners)
provisioned with public intermediate key and secret signing key
Old concrete specs were slipping through in `_assign_hash`, and `package_hash` was
attempting to recompute a package hash when we could not know the package a time
of concretization.
Part of this was that the logic for `_assign_hash` was hard to understand -- it was
called twice from `_finalize_concretization` and had special cases for both args it
was called with. It's much easier to understand the logic here if we just inline it.
- [x] Get rid of `_assign_hash` and just integrate it with `_finalize_concretization`
- [x] Don't call `_package_hash` at all for already-concrete specs.
- [x] Add regression test.
This PR introduces a new build cache layout and package format, with improvements for
both efficiency and security.
## Old Format
Currently a binary package consists of a `spec.json` file at the root and a `.spack` file,
which is a `tar` archive containing a copy of the `spec.json` format, possibly a detached
signature (`.asc`) file, and a tar-gzip compressed archive containing the install tree.
```
build_cache/
# metadata (for indexing)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
<arch>/
<compiler>/
<name>-<ver>/
# tar archive
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spack
# tar archive contents:
# metadata (contains sha256 of internal .tar.gz)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
# signature
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json.asc
# tar.gz-compressed prefix
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.tar.gz
```
After this change, the nesting has been removed so that the `.spack` file is the
compressed archive of the install tree. Now signed binary packages, will take the
form of a clearsigned `spec.json` file (a `spec.json.sig`) at the root, while unsigned
binary packages will contain a `spec.json` at the root.
## New Format
```
build_cache/
# metadata (for indexing, contains sha256 of .spack file)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
# clearsigned spec.json metadata
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json.sig
<arch>/
<compiler>/

## Benefits
The major benefit of this change is that the signatures on binary packages can be
verified without:
1. Having to download the tarball, or
2. having to extract an unknown tarball.
(1) is an improvement in efficiency; (2) is a security fix: we now ensure that we trust the
binary before we try to run it through `tar`, which avoids potential attacks.
## Backward compatibility
Also after this change, spack should still be able to handle the previous buildcache
structure and binary mirrors with mixed layouts.
This PR builds on #28392 by adding a convenience command to create a local mirror that can be used to bootstrap Spack. This is to overcome the inconvenience in setting up this mirror manually, which has been reported when trying to setup Spack on air-gapped systems.
Using this PR the user can create a bootstrapping mirror, on a machine with internet access, by:
% spack bootstrap mirror --binary-packages /opt/bootstrap
==> Adding "clingo-bootstrap@spack+python %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
==> Adding "gnupg@2.3: %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
==> Adding "patchelf@0.13.1:0.13.99 %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
==> Adding binary packages from "https://github.com/alalazo/spack-bootstrap-mirrors/releases/download/v0.1-rc.2/bootstrap-buildcache.tar.gz" to the mirror at /opt/bootstrap/local-mirror
To register the mirror on the platform where it's supposed to be used run the following command(s):
% spack bootstrap add --trust local-sources /opt/bootstrap/metadata/sources
% spack bootstrap add --trust local-binaries /opt/bootstrap/metadata/binaries
The mirror has to be moved over to the air-gapped system, and registered using the commands shown at prompt. The command has options to:
1. Add pre-built binaries downloaded from Github (default is not to add them)
2. Add development dependencies for Spack (currently the Python packages needed to use spack style)
* bootstrap: refactor bootstrap.yaml to move sources metadata out
* bootstrap: allow adding/removing custom bootstrapping sources
This operation can be performed from the command line since
new subcommands have been added to `spack bootstrap`
* Add --trust argument to spack bootstrap add
* Add a command to generate a local mirror for bootstrapping
* Add a unit test for mirror creation
Currently, environments can either be concretized fully together or fully separately. This works well for users who create environments for interoperable software and can use `concretizer:unify:true`. It does not allow environments with conflicting software to be concretized for maximal interoperability.
The primary use-case for this is facilities providing system software. Facilities provide multiple MPI implementations, but all software built against a given MPI ought to be interoperable.
This PR adds a concretization option `concretizer:unify:when_possible`. When this option is used, Spack will concretize specs in the environment separately, but will optimize for minimal differences in overlapping packages.
* Add a level of indirection to root specs
This commit introduce the "literal" atom, which comes with
a few different "arities". The unary "literal" contains an
integer that id the ID of a spec literal. Other "literals"
contain information on the requests made by literal ID. For
instance zlib@1.2.11 generates the following facts:
literal(0,"root","zlib").
literal(0,"node","zlib").
literal(0,"node_version_satisfies","zlib","1.2.11").
This should help with solving large environments "together
where possible" since later literals can be now solved
together in batches.
* Add a mechanism to relax the number of literals being solved
* Modify spack solve to display the new criteria
Since the new criteria is above all the build criteria,
we need to modify the way we display the output.

to this branch by the co-author of the commit.

* Inject reusable specs into the solve
Instead of coupling the PyclingoDriver() object with
spack.config, inject the concrete specs that can be
reused.
A method level function takes care of reading from
the store and the buildcache.
* spack solve: show output of multi-rounds
* add tests for best-effort coconcretization
* Enforce having at least a literal being solved

Previously the regex was only checking for presence of quotes as a beginning
or end character and not a matching set. This erroneously identified the
following *single* argument as being quoted:
source bashenvfile &> /dev/null && python3 -c "import os, json; print(json.dumps(dict(os.environ)))"
Add a config option to strip `-Werror*` or `-Werror=*` from compile lines everywhere.
```yaml
config:
keep_werror: false
```
By default, we strip all `-Werror` arguments out of compile lines, to avoid unwanted
failures when upgrading compilers. You can re-enable `-Werror` in your builds if
you really want to, with either:
```yaml
config:
keep_werror: all
```
or to keep *just* specific `-Werror=XXX` args:
```yaml
config:
keep_werror: specific
```
This should make swapping in newer versions of compilers much smoother when
maintainers have decided to enable `-Werror` by default.
Parse error information is kept for specs, but it doesn't seem like we propagate it
to the user when we encounter an error. This fixes that.
e.g., for this error in a package:
```python
depends_on("python@:3.8", when="0.900:")
```
Before, with no context and no clue that it's even from a particular spec:
```
==> Error: Unexpected token: ':'
```
With this PR:
```
==> Error: Unexpected token: ':'
Encountered when parsing spec:
0.900:
^
```
* Introduce concretizer:unify option to replace spack:concretization
* Deprecate concretization
* Make spack:concretization overrule concretize:unify for now
* Add environment update logic to move from spack:concretization to spack:concretizer:reuse
* Migrate spack:concretization to spack:concretize:unify in all locations
* For new environments make concretizer:unify explicit, so that defaults can be changed in 0.19
The oneapi and dpcpp compilers are essentially the same except for which
binary is used foc CXX. Spack will detect them as "mixed toolchain" and
not inject compiler optimization flags. This will be needed once
archspec has entries for the oneapi and dpcpp compilers. This PR detects
when dpcpp and oneapi are in the toolchains list and explicitly sets
`is_mixed_toolchain` to `False`.
