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>/
<name>-<ver>/
# tar.gz-compressed prefix (may support more compression formats later)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spack
```
## 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.

* 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`.
Error messages for the clingo concretizer have proven challenging. The current messages are incredibly vague and often don't help users at all. Unsat cores in clingo are not guaranteed to be minimal, and lead to cores that are either not useful or need to be post-processed for hours to reach a minimal core.
Following up on an idea from a slack conversation with kwryankrattiger on slack, this PR takes a new approach. We eliminate most integrity constraints and minima/maxima on choice rules in clingo, and instead force invalid states to imply an error predicate. The error predicate can include context on the cause of the error (Package, Version, etc). These error predicates are then heavily optimized against, to ensure that we do not include error facts in the solution when a solution with no error facts could be generated. When post-processing the clingo solution to construct specs, any error facts cause the program to raise an exception. This leads to much more legible error messages. Each error predicate includes a priority and an error message. The error message is formatted by the remaining arguments to produce the error message. The priority is used to ensure that when clingo has a choice of which rules to violate, it chooses the one which will be most informative to the user.
Performance:
"fresh" concretizations appear to suffer a ~20% performance penalty under this branch, while "reuse" concretizations see a speedup of around 33%.
Possible optimizations if users still see unhelpful messages:
There are currently 3 levels of priority of the error messages. Additional priorities are possible, and can allow us finer granularity to ensure more informative error messages are provided in lieu of less informative ones.
Future work:
Improve tests to ensure that every possible rule implying an error message is exercised
A non-existent upstream should not be fatal: it could only mean it is
not deployed yet. In the meantime, it should not block the user to
rebuild anything it needs.
A warning is still emitted, to let the user decide if this is ok or not.

Trying to compute `dag_hash()` or `package_hash()` on a concrete spec that doesn't have
a `_package_hash` attribute would attempt to recompute the package hash.
This most commonly manifests as a failed lookup of a namespace if you attempt to uninstall
or compute the hashes of packages in exsternal repositories that aren't registered, e.g.:
```console
> spack spec --json c/htno
==> Error: Unknown namespace: myrepo
```
While it wouldn't change the already-assigned `dag_hash` value, this behavior is
incorrect, since the package file for a previously concrete spec:
1. might have changed since concretization,
2. might not exist anymore, or
3. might just not be findable by Spack.
This PR ensures that the package hash can't be computed on older concrete specs. Instead
of calling `package_hash()` from within `to_node_dict()`, we now check for the `_package_hash`
attribute and only add the package_hash to the spec record if it's there.
This PR also handles the tricky semantics of computing `package_hash()` at concretization
time. We have to compute it *before* marking the spec concrete so that `to_node_dict` can
use it. But this means that the logic for `package_hash()` can't rely on `spec.concrete`,
as it is called *during* concretization. Instead of checking for concreteness, `package_hash()`
now checks `_patches_assigned()` to determine whether it should add them to the package
hash.
- [x] Add an assert to `package_hash()` so it can't be called on specs for which it
would be wrong.
- [x] Add an `_assign_hash()` method to handle tricky semantics of `package_hash`
and `dag_hash`.
- [x] Rework concretization to call `_assign_hash()` before and after marking specs
concrete.
- [x] Rework content hash part of package hash to check for `_patches_assigned()`
instead of `spec.concrete`.
- [x] regression test
Previously we sorted by hash values for `spack graph`, but changing hashes can make the
test brittle and the node order seem nondeterministic to users.
- [x] Sort nodes in `spack graph` by the default edge order, which takes into account
parent and child names as well as dependency types.
- [x] Update ASCII test output for new order.
The dependency check currently checks whether there are only build
dependencies left for a particular package. However, the database also
contains uninstalled packages, which can cause the check to fail.
For instance, with `bison` and `flex` having already been uninstalled,
`m4` will have the following dependents:
```
bison ('build', 'run')--> m4
flex ('build',)--> m4
libnl ('build',)--> m4
```
`bison` and `flex` should be ignored in this case because they are not
installed anymore.
Fixes#30673
#24556 merged in support for Python's .zip file support via ZipFile.
However as per #30200 ZipFile does not preserve file permissions of
the extracted contents. This PR returns to using the `unzip`
executable on non-Windows systems (as was the case before #24556)
and now uses `tar` on Windows to extract .zip files.
We previously had checks in `directory_layout` to check for build-dependency
conflicts when we weren't storing build dependencies. We don't need
those anymore; we can just rely on the DAG hash now that it includes everything
we know about each spec.
- [x] Remove vestigial code for checking installed spec against concrete spec
in `ensure_installed()`
- [x] Remove `SpecHashCollisionError` -- if specs have the same hash now, they're
the same as far as `DirectoryLayout` should be concerned.
- [x] Convert spec comparison to `dag_hash()` comparison when adding extensions.
The database now stores full hashes, so we need to adjust the criteria we use to
determine if something can be uninstalled. Specifically, it's ok to uninstall thing that
have remaining build-only dependents.
With the original DAG hash, we did not store build dependencies in the database, but
with the full DAG hash, we do. Previously, we'd never tell the concretizer about build
dependencies of things used by hash, because we never had them. Now, we have to avoid
telling the concretizer about them, or they'll unnecessarily constrain build
dependencies for new concretizations.
- [x] Make database track all dependencies included in the `dag_hash`
- [x] Modify spec_clauses so that build dependency information is optional
and off by default.
- [x] `spack diff` asks `spec_clauses` for build dependencies for completeness
- [x] Modify `concretize.lp` so that reuse optimization doesn't affect fresh
installations.
- [x] Modify concretizer setup so that it does *not* prioritize installed versions
over package versions. We don't need this with reuse, so they're low priority.
- [x] Fix `test_installed_deps` for full hash and new concretizer (does not work
for old concretizer with full hash -- leave this for later if we need it)
- [x] Move `test_installed_deps` mock packages to `builtin.mock` for easier debugging
with `spack -m`.
- [x] Fix `test_reuse_installed_packages_when_package_def_changes` for full hash
- [x] update test to use `build_hash` instead of `dag_hash`, as we're testing for
graph structure, and specifically NOT testing for package changes.
- [x] make hash descriptors callable on specs to simplify syntax for invoking them
- [x] make `Spec.spec_hash()` public
This removes all but one usage of runtime hash. The runtime hash was being used to write
historical lockfiles for tests, but we don't need it for that; we can just save those
lockfiles.
- [x] add legacy lockfiles for v1, v2, v3
- [x] fix bugs with v1 lockfile tests (the dummy lockfile we were writing was not actually
a v1 lockfile because it used the new spec file format).
- [x] remove all but one runtime_hash usage -- that one needs a small rework of the
concretizer to really fix, as it's about separate concretization of build
dependencies.
- [x] Document the history of the lockfile format in `environment/__init__.py`
Some test cases had to be modified in a kludgy way so that abstract specs made
concrete would have versions on them. We shouldn't *need* to do this, as the
only reason we care is because the content hash has to be able to get an archive
for a version.
This modifies the content hash so that it can be called on abstract specs,
including only relevant content.
This does NOT add a partial content hash to the DAG hash, as we do not really
want that -- we don't need in-memory spec hashes to need to load package files.
It just makes `Package.content_hash()` less prickly and tests easier to
understand.
`spack monitor` expects a field called `spec_full_hash`, so we shouldn't change that.
Instead, we can pass a `dag_hash` (which is now the full hash) but not change the field
name.
`hashes_final` was used to indicate when a spec was concrete but possibly lacked
`full_hash` or `build_hash` fields. This was only necessary because older Spacks
didn't generate them, and we want to avoid recomputing them, as we likely do not
have the same package files as existed at concretization time.
Now, we don't need to do that -- there is only the DAG hash and specs are either
concrete and have a `dag_hash`, or not concrete and have no `dag_hash`. There's
no middle ground.
Without some enforcement of spec ordering, python 2 produced
different results in the affected test than did python 3. This
change makes the arbitrary but reproducible decision to sort
the specs by their lockfile key alphabetically.
The full hash appears twice in the spec dict now, replacing just
the value replaces it under "hash" and "full_hash". Only replace
the one that appears after "full_hash".
I'm actually not sure what purpose this test served, so maybe it
could be removed, as it may be testing some distinction between
full and dag hash which no longer exists.
For a long time, Spack has used a coarser hash to identify packages
than it likely should. Packages are identified by `dag_hash()`, which
includes only link and run dependencies. Build dependencies are
stripped before hashing, and we have notincluded hashes of build
artifacts or the `package.py` files used to build. This means the
DAG hash actually doesn't represent all the things Spack can build,
and it reduces reproducibility.
We did this because, in the early days, users were (rightly) annoyed
when a new version of CMake, autotools, or some other build dependency
would necessitate a rebuild of their entire stack. Coarsening the hash
avoided this issue and enabled a modicum of stability when only reusing
packages by hash match.
Now that we have `--reuse`, we don't need to be so careful. Users can
avoid unnecessary rebuilds much more easily, and we can add more
provenance to the spec without worrying that frequent hash changes
will cause too many rebuilds.
This commit starts the refactor with the following major change:
- [x] Make `Spec.dag_hash()` include build, run, and link
dependencides and the package hash (it is now equivalent to
`full_hash()`).
It also adds a couple of bugfixes for problems discovered during
the switch:
- [x] Don't add a `package_hash()` in `to_node_dict()` unless
the spec is concrete (fixes breaks on abstract specs)
- [x] Don't add source ids to the package hash for packages without
a known fetch strategy (may mock packages are like this)
- [x] Change how `Spec.patches` is memoized. Using
`llnl.util.lang.memoized` on `Spec` objects causes specs to
be stored in a `dict`, which means they need a hash. But,
`dag_hash()` now includes patch `sha256`'s via the package
hash, which can lead to infinite recursion
`spack pkg list` tests were broken by #29593 for cases when your `builtin.mock` repo
still has stale backup files (or, really, stale directories) sitting around. This
happens if you switch branches a lot. In this case, things like this were causing
erroneous packages in the mock listing:
```
var/spack/repos/builtin.mock/packages/
foo/
package.py~
```
- [x] make `list_packages` consider only directories with one-deep `package.py` files.
Reworking lua to allow easier substitution of the base lua implementation.
Also adding in a maintained version of luajit and re-factoring the entire stack
to use a custom build-system to centralize functionality like environment
variable management and luarocks installation.
The `lua-lang` virtual is now versioned so that a package that requires
Lua 5.1 semantics can get any lua, but one that requires 5.2 will only
get upstream lua.
The luaposix package requires lua-bit32, but only when built with a
lua conforming to version 5.1. This adds the package, and the
dependencies, but exposed a problem with luarocks dependency
detection. Since we're installing each package in its own "tree" and
there's no environment variable to list extra trees, spack now
generates a luarocks config file that lists all the trees of all the
dependencies, and references it by setting `LUAROCKS_CONFIG`
in the build environment of every LuaPackage. This allows luarocks
to find the spack installed dependencies correctly rather than
trying (and failing) to download them.

When running on Windows, Spack may generate files in the stage/install
prefixes that do not have write permissions, which prevents the
removal of those directories (e.g. when cleaning stages or uninstalling).
There should be a refactoring to avoid this in the first place, but that
is assumed to be longer term, so the temporary fix is to make such files
writable if they are not. This PR:
* Automatically handles these permissions errors when uninstalling
packages from the Spack root (makes then writable)
* Updates similar already-existing logic when removing Spack-managed
stage directories (the error-handling was assuming all errors were
permissions errors and was therefore handling other errors
inappropriately)
Note: these permissions issues only appear on Windows so this logic is
only applied there (permissions are not modified for this purpose on
Linux etc.).
This also adds special handling for a case where calling `isdir`
on an `os.DirEntry` object would fail for improperly-created symlinks
(e.g. on Windows, using `os.symlink` without `target_is_directory=True`).
Note this specific issue only came up when enabling link_tree tests
(specifically `source_merge_visitor_cant_be_cyclical`).
* create function for translating compiler names on specs/compiler entries in manifest
* add tests for translating compiler names on spec/compiler entries
* use higher-level function in test and add comment to prefer testing via higher-level function
* opensuse clingo check should not fail on account of this pr, but I cannot get it to pass by restarting via CI UI
* Force GCC to always provide a C++14 flag
Updated gnu logic so that the c++14 flag for g++ is always propagated.
This fixes issues with build systems that error out if passed an empty
string for a flag.
Engaging in the best kind of software engineering by updating the unit
test to pass with the value it is now passed. This should better match
the expected flag for g++ compiling with the C++14 standard
This ensures that multiple spack instances called from `make` will respect the maximum number of jobs in the POSIX jobserver across packages.

`make` solves a lot of headaches that would otherwise have to be implemented in Spack:

2. Orderly output of parallel package installs thanks to `make --sync-output=recurse` or `make -Orecurse` (works well in GNU Make 4.3; macOS is unfortunately on a 16 years old 3.x version, but it's one `spack install gmake` away...)
3. Shared jobserver across packages, which means a single `-j` to rule them all, instead of manually finding a balance between `#spack install processes` & `#jobs per package` (See #30302).
This pr adds the `spack env depfile` command that generates a Makefile with dag hashes as
targets, and dag hashes of dependencies as prerequisites, and a command
along the lines of `spack install --only=packages /hash` to just install
a single package.
It exposes two convenient phony targets: `all`, `fetch-all`. The former installs the environment, the latter just fetches all sources. So one can either use `make all -j16` directly or run `make fetch-all -j16` on a login node and `make all -j16` on a compute node.
Example:
```yaml
spack:
specs: [perl]
view: false
```
running
```
$ spack -e . env depfile --make-target-prefix env | tee Makefile
```
generates
```Makefile

Then with `make -O` you get very nice orderly output when packages are built in parallel:
```console
$ make -Orecurse -j16
spack -e . install --only-concrete --only=package /c4go4gxlcznh5p5nklpjm644epuh3pzc && touch c4go4gxlcznh5p5nklpjm644epuh3pzc

```
For Perl, at least for me, using `make -j16` versus `spack -e . install -j16` speeds up the builds from 3m32.623s to 2m22.775s, as some configure scripts run in parallel.
Another nice feature is you can do Makefile "metaprogramming" and depend on packages built by Spack. This example fetches all sources (in parallel) first, print a message, and only then build packages (in parallel).
```Makefile
SPACK ?= spack
.PHONY: env
all: env
spack.lock: spack.yaml
$(SPACK) -e . concretize -f
env.mk: spack.lock
$(SPACK) -e . env depfile -o $@ --make-target-prefix spack

@echo Fetched all packages && touch $@
env: fetch spack/env
@echo This executes after the environment has been installed
clean:
rm -rf spack/ env.mk spack.lock

endif
```
Added support for finding the OpenCV package via the find external
command. Included support for identifying variants based on available
shared libraries.
Added support to finding the OpenBLAS package via the find external
command.
Enabled packages to show that they can be discovered via the find
external command in the info message.
Updated the OpenCV and OpenBLAS packages to use the extensible search
mechanism for library extensions on multiple OS platforms.
Corrected how find externals works on Darwin for OpenCV and OpenBLAS
to accommodate that the version numbers are placed before the file
extension instead of after it, as on Linux.

This is an amended version of https://github.com/spack/spack/pull/24894 (reverted in https://github.com/spack/spack/pull/29603). https://github.com/spack/spack/pull/24894
broke all instances of `spack external find` (namely when it is invoked without arguments/options)
because it was mandating the presence of a file which most systems would not have.
This allows `spack external find` to proceed if that file is not present and adds tests for this.
- [x] Add a test which confirms that `spack external find` successfully reads a manifest file
if present in the default manifest path
--- Original commit message ---
Adds `spack external read-cray-manifest`, which reads a json file that describes a
set of package DAGs. The parsed results are stored directly in the database. A user
can see these installed specs with `spack find` (like any installed spec). The easiest
way to use them right now as dependencies is to run
`spack spec ... ^/hash-of-external-package`.
Changes include:
* `spack external read-cray-manifest --file <path/to/file>` will add all specs described
in the file to Spack's installation DB and will also install described compilers to the
compilers configuration (the expected format of the file is described in this PR as well including examples of the file)
* Database records now may include an "origin" (the command added in this PR
registers the origin as "external-db"). In the future, it is assumed users may want
to be able to treat installs registered with this command differently (e.g. they may
want to uninstall all specs added with this command)
* Hash properties are now always preserved when copying specs if the source spec
is concrete
* I don't think the hashes of installed-and-concrete specs should change and this
was the easiest way to handle that
* also specs that are concrete preserve their `.normal` property when copied
(external specs may mention compilers that are not registered, and without this
change they would fail in `normalize` when calling `validate_or_raise`)
* it might be this should only be the case if the spec was installed
- [x] Improve testing
- [x] Specifically mark DB records added with this command (so that users can do
something like "uninstall all packages added with `spack read-external-db`)
* This is now possible with `spack uninstall --all --origin=external-db` (this will
remove all specs added from manifest files)
- [x] Strip variants that are listed in json entries but don't actually exist for the package
* ASP-based solver: discard unknown packages from reuse
This is an add-on to #28259 that cover for the case of
a single package.py being removed from a repository,
rather than an entire custom repository being removed.
* Add unit test
CTest determines whether to enable tests using the BUILD_TESTING variable.
This should be used by projects to conditionally enable the compilation of tests.
Spack knowns which packages have to run tests and can thus automatically define this variable.
I tried to use --overwrite on nvhpc, but nvhpc's install size is 16GB. Seems
better to do os.rename in the same directory than moving the directory to
`/tmp`.
- [x] install --overwrite: use rename instead of tmpdir
- [x] use tempfile
fixes#28259
This commit discard specs from unknown namespaces from the
ones that can be "reused" during concretization. Previously
Spack would just error out when encountering them.
The parent thread in the process stdout redirection logic on Windows
was closing a file that was being read in child thread, which lead to
error-based termination of the reader thread. This updates the
interaction to avoid the error.
* ASP-based solver: allow configuring target selection
This commit adds a new "concretizer:targets" configuration
section, and two options under it.
- "concretizer:targets:granularity" allows switching from
considering only generic targets to consider all possible
microarchitectures.
- "concretizer:targets:host_compatible" instead controls
whether we can concretize for microarchitectures that
are incompatible with the current host.
* Add documentation
* Add unit-tests
* ASP-based solver: always consider version of installed packages
fixes#29201
Explicitly add facts for versions of installed software when
using the --reuse option, so that we could consider versions
that are not declared in package.py
The parser is already committing a crime of querying the database for
specs when it encounters a `/hash`. It's helpful, but unfortunately not
helpful when trying to install a specific spec in an environment by
hash. Therefore, consider the environment first, then the database.
This allows the following:
```console
$ spack -e . concretize
==> Starting concretization
==> Environment concretized in 0.27 seconds.
==> Concretized diffutils

```
Fix bug introduced in #30191. `Spec.installed` and `Spec.installed_upstream` should just return
`False` for abstract specs, as they can be called in that context.
- [x] `Spec.installed` returns `False` now instead of asserting that the `Spec`
is concrete.
- [x] `Spec.installed_upstream` returns `False` now instead of asserting that the `Spec`
is concrete.
- [x] `Spec.installed_upstream` no longer caches its result, as install status seems
like a bad thing to cache -- it can easily be invalidated. Calling code should
use transactions if there are peformance issues, as with other places in Spack.
- [x] add tests for `Spec.installed` and `Spec.installed_upstream`
This PR moves the `installed` and `installed_upstream` properties from `PackageBase` to `Spec` and is a step towards being able to reuse specs for which we don't have a `package.py` available. It _should_ be sufficient to complete the concretization step and see the spec in the concretized DAG.
To fully reuse a spec without a package.py though we need a way to serialize enough data to reconstruct the results of calls to:
- `Spec.libs`, `Spec.headers` and `Spec.ommand`
- `Package.setup_dependent_*_environment` and `Package.setup_run_environment`
- [x] Add stub methods to packages with warnings
- [x] Add a missing "root=False" in cmd/fetch.py
- [x] Assert that a spec is concrete before checking installation status
This PR updates the list of images we build nightly, deprecating
Ubuntu 16.04 and CentOS 8 and adding Ubuntu 20.04, Ubuntu 22.04
and CentOS Stream. It also removes a lot of duplication by generating
the Dockerfiles during the CI workflow and uploading them as artifacts
for later inspection or reuse.
Fix test_ci_generate_prune_untouched(), which would fail if run when
the latest commit changed the .gitlab-ci.yml. This change mocks the
get_stack_changed() method in that test to disregard the state of
the current spack repo in favor of a mock repo under test control.
gitlab ci: Remove code for relating CDash builds
Relating CDash builds to their dependencies was a seldom used feature. Removing
it will make it easier for us to reorganize our CDash projects & build groups in the
future by eliminating the needs to keep track of CDash build ids in our binary mirrors.
* Allow packages to add a 'submodules' property that determines when ad-hoc Git-commit-based versions should initialize submodules
* add support for ad-hoc git-commit-based versions to instantiate submodules if the associated package has a 'submodules' property and it indicates this should happen for the associated spec
* allow Package-level submodule request to influence all explicitly-defined version() in the Package
* skip test on windows which fails because of long paths
Spack added support in #24639 for ad-hoc Git-commit-hash-based
versions: A user can install a package x@hash, where X is a package
that stores its source code in a Git repository, and the hash refers
to a commit in that repository which is not recorded as an explicit
version in the package.py file for X.
A couple issues were found relating to this:
* If an environment defines an alternative package repo (i.e. with
repos.yaml), and spack.yaml contains user Specs with ad-hoc
Git-commit-hash-based versions for packages in that repo,
then as part of retrieving the data needed for version comparisons
it will attempt to retrieve the package before the environment's
configuration is instantiated.
* The bookkeeping information added to compare ad-hoc git versions was
being stripped from Specs during concretization (such that user
Specs which succeeded before concretizing would then fail after)
This addresses the issues:
* The first issue is resolved by deferring access to the associated
Package until the versions are actually compared to one another.
* The second issue is resolved by ensuring that the Git bookkeeping
information is explicitly applied to Specs after they are concretized.
This also:
* Resolves an ambiguity in the mock_git_version_info fixture used to
create a tree of Git commits and provide a list where each index
maps to a known commit.
* Isolates the cache used for Git repositories in tests using the
mock_git_version_info fixture
* Adds a TODO which points out that if the remote Git repository
overwrites tags, that Spack will then fail when using
ad-hoc Git-commit-hash-based versions
This commit updates the `gpg publish` command to work with the mirror
arguments, when trying to push keys to a mirror.
- [x] update `gpg publish command
- [x] add test for publishing GPG keys and rebuilding the key index within a mirror
In a typical call to spack, the OperatingSystem gets instantiated
multiple times. For macOS, each one requires a call to `sw_vers`, which
is done through the Executable helper class. Memoizing
reduces the call count from "spac spec" from three to one.
Currently environments are indexed by build hashes. When looking into this bug I noticed there is a disconnect between environments that are concretized in memory for the first time and environments that are read from a `spack.lock`. The issue is that specs read from a `spack.lock` don't have a full hash, since they are indexed by a build hash which is strictly coarser. They are also marked "final" as they are read from a file, so we can't compute additional hashes.
This bugfix PR makes "first concretization" equivalent to re-reading the specs from a corresponding `spack.lock`, and doing so unveiled a few tests were we were making wrong assumptions and relying on the fact that a `spack.lock` file was not there already.
* Add unit test
* Modify mpich to trigger jobs in pipelines
* Fix two failing unit tests
* Fix another full_hash vs. build_hash mismatch in tests
* Ignore top-level module config; add auto-update
In Spack 0.17 we got module sets (modules:[name]:[prop]), and for
backwards compat modules:[prop] was short for modules:default:[prop].
But this makes it awkward to define default config for the "default"
module set.
Since 0.17 is branched off, we can now deprecate top-level module config
(that is, just ignore it with a warning).
This PR does that, and it implements `spack config update modules` to
make upgrading easy (we should have added that to 0.17 already...)
It also removes references to `dotkit` stuff which was already
deprecated in 0.13 and could have been removed in 0.14.
Prefix inspections are the only exception, since the top-level prefix inspections
used for `spack load` and `spack env activate`.
Spack currently allows dependencies to be concretized for an
architecture incompatible with the root. This commit adds rules
to make this situation impossible by design.
* Extract the MetaPathFinder and Loaders for packages in their own classes
https://peps.python.org/pep-0451/
Currently, RepoPath and Repo implement the (deprecated) interface of
MetaPathFinder (find_module) and of Loader (load_module). This commit
extracts both of them and places the code in their own classes.
The MetaPathFinder interface is updated to contain both the deprecated
"find_module" (for Python 2.7 support) and the recommended "find_spec".
Update of the Loader interface is deferred at a subsequent commit.
* Move the lines to be prepended inside "RepoLoader"
Also adjust the naming of a few variables too
* Remove spack.util.imp, since code is only used in spack.repo
* Remove support from loading Python modules Python > 3 but < 3.5
* Remove `Repo._create_namespace`
This function was interacting badly with the MetaPathFinder
and causing issues with "normal" imports. Removing the
function allows to do things like:
```python
import spack.pkg.builtin.mpich
cls = spack.pkg.builtin.mpich.Mpich
```
* Remove code needed to trigger the Singleton evaluation
The finder is coded in a way to trigger the Singleton,
so we don't need external code now that we register it
at module level into `sys.meta_path`.
* Add unit tests
Some servers require `User-Agent` to be set, and otherwise error with
access denied. One such example is mpich.
To fix this, set `User-Agent: Spackbot/[version]` as a header.
Apparently by convention, it should include the word `bot`.
#27021 broke fetching for CVS-based packages because:
- The mirror logic was using URL parsing to extract a path from the
CVS repository location
- #27021 added sanity checks to enforce that strings passed to the
URL parser were actually URLs
This replaces the call to "url_util.parse" with logic that is
customized for CVS. This implies that VCSFetchStrategy should
rename the "url_attr" attribute to something more generic, but
that should be handled separately.
Allow declaring possible values for variants with an associated condition. If the variant takes one of those values, the condition is imposed as a further constraint.
The idea of this PR is to implement part of the mechanisms needed for modeling [packages with multiple build-systems]( https://github.com/spack/seps/pull/3). After this PR the build-system directive can be implemented as:
```python
variant(
'build-system',
default='cmake',
values=(
'autotools',
conditional('cmake', when='@X.Y:')
),
description='...',
)
```
Modifications:
- [x] Allow conditional possible values in variants
- [x] Add a unit-test for the feature
- [x] Add documentation
* tests for rewiring pure specs to spliced specs
* relocate text, binaries, and links
* using llnl.util.symlink for windows compat.
Note: This does not include CLI hooks for relocation.

- Add variants for various common build flags, including support for both versions of the Racket VM environment.
- Prevent `-j` flags to `make`, which has been known to cause problems with Racket builds.
- Prefer the minimal release to improve install times. Bells and whistles carry their own runtime dependencies and should be installed via `raco`. An enterprising user may even create a `RacketPackage` class to make spack aware of `raco` installed packages.
- Match the official version numbering scheme.
Update "spack external find --all" to also find library-only packages.
A Package can add a ".libraries" attribute, which is a list of regular
expressions to use to find libraries associated with the Package.
"spack external find --all" will search LD_LIBRARY_PATH for potential
libraries.
This PR adds examples for NCCL, RCCL, and hipblas packages. These
examples specify the suffix ".so" for the regular expressions used
to find libraries, so generally are only useful for detecting library
packages on Linux.
Do not prompt user with checksum warning when using git commit hashes
as versions. Spack was incorrectly reporting this as a potential
problem: it would display a prompt asking the user whether they
want to proceed if Spack was running in a terminal, or it would
terminate the running instance of Spack if running as part of a
script.
* Add pl2bat to PATH: Windows on Perl requires the script pl2bat.bat
and Perl to be available to the installer via the PATH. The build
and dependent environments of Perl on Windows have the install
prefix bin added to the PATH.
* symlink with win32file module instead of using Executable to
call mklink (mklink is a shell function and so is not accessible
in this manner).
We've previously generated CI pipelines for PRs, and they rebuild any packages that don't have
a binary in an existing build cache. The assumption we were making was that ALL prior merged
builds would be in cache, but due to the way we do security in the pipeline, they aren't. `develop`
pipelines can take a while to catch up with the latest PRs, and while it does that, there may be a
bunch of redundant builds on PRs that duplicate things being rebuilt on `develop`. Until we can
do better caching of PR builds, we'll have this problem.
We can do better in PRs, though, by *only* rebuilding things in the CI environment that are actually
touched by the PR. This change computes exactly what packages are changed by a PR branch and
*only* includes those packages' dependents and dependencies in the generated pipeline. Other
as-yet unbuilt packages are pruned from CI for the PR.
For `develop` pipelines, we still want to build everything to ensure that the stack works, and to ensure
that `develop` catches up with PRs. This is especially true since we do not do rebuilds for *every* commit
on `develop` -- just the most recent one after each `develop` pipeline finishes. Since we skip around,
we may end up missing builds unless we ensure that we rebuild everything.
We differentiate between `develop` and PR pipelines in `.gitlab-ci.yml` by setting
`SPACK_PRUNE_UNTOUCHED` for PRs. `develop` will still have the old behavior.
- [x] Add `SPACK_PRUNE_UNTOUCHED` variable to `spack ci`
- [x] Refactor `spack pkg` command by moving historical package checking logic to `spack.repo`
- [x] Implement pruning logic in `spack ci` to remove untouched packages
- [x] add tests
* cmake: use CMAKE_INSTALL_RPATH_USE_LINK_PATH
Spack has a heuristic to add rpaths for packages it knows are required,
but it's really a heuristic, and it does not work when the dependencies
put their libraries in a different folder than `<prefix>/lib{64,}`.
CMake patches binaries after install with the "install rpaths", which by
default are provided by Spack and its heuristic through
`CMAKE_INSTALL_RPATH`.
CMake however knows better what libraries are effectively being linked
to, and has an option to include those in the install rpath too, through
`CMAKE_INSTALL_RPATH_USE_LINK_PATH`.
These two CMake options are complementary, repeated rpaths seem to be
filtered, and the "use link path" paths are appended to Spack's
heuristic "install rpath".
So, it seems like a good idea to enable "use link path" by default, so
that:
- `dlopen` by library name uses Spack's heuristic search paths
- linked libraries in non-standard locations within a prefix get an
rpath thanks to CMake.

Add output of build- and install-time tests to info command
Enable dependencies, variants, and versions by default (i.e., provide --no*
options; add gcc to test_info_fields to increase coverage for c_names->v_names
