A common question from users has been how to model variants
that are new in new versions of a package, or variants that are
dependent on other variants. Our stock answer so far has been
an unsatisfying combination of "just have it do nothing in the old
version" and "tell Spack it conflicts".
This PR enables conditional variants, on any spec condition. The
syntax is straightforward, and matches that of previous features.
When relocating a binary distribution, Spack only checks files to see
if they are a link that needs to be relocated. Directories can be
such links as well, however, and need to undergo the same checks
and potential relocation.
* Speed-up environment concretization with a process pool
We can exploit the fact that the environment is concretized
separately and use a pool of processes to concretize it.
* Add module spack.util.parallel
Module includes `pool` and `parallel_map` abstractions,
along with implementation details for both.
* Add a new hash type to pass specs across processes
* Add tty msg with concretization time
Using the Spec.constrain method doesn't work since it might
trigger a repository lookup which could break our directives
and triggers a circular import error.
To fix that we introduce a function to merge abstract anonymous
specs, based only on package names, which does not perform any
lookup in the repository.
The buildcache is now extracted in a temporary folder within the current store,
moved to its final place and relocated.
"spack clean -s" has been extended to also clean the temporary extraction directory.
Add hardlinks with absolute paths for libraries in the corge, garply and quux packages
to detect incorrect handling of hardlinks in tests.
The ASP-based solver maximizes the number of values in multi-valued
variants (if other higher order constraints are met), to avoid cases
where only a subset of the values that have been specified on the
command line or imposed by another constraint are selected.
Here we swap the priority of this optimization target with the
selection of the default providers, to avoid unexpected results
like the one in #26598
The `spack.architecture` module contains an `Arch` class that is very similar to `spack.spec.ArchSpec` but points to platform, operating system and target objects rather than "names". There's a TODO in the class since 2016:
abb0f6e27c/lib/spack/spack/architecture.py (L70-L75)
and this PR basically addresses that. Since there are just a few places where the `Arch` class was used, here we query the relevant platform objects where they are needed directly from `spack.platforms`. This permits to clean the code from vestigial logic.
Modifications:
- [x] Remove the `spack.architecture` module and replace its use by `spack.platforms`
- [x] Remove unneeded tests
* Use gnuconfig package for config file replacement
Currently the autotools build system tries to pick up config.sub and
config.guess files from the system (in /usr/share) on arm and power.
This is introduces an implicit system dependency which we can avoid by
distributing config.guess and config.sub files in a separate package,
such as the new `gnuconfig` package which is very lightweight/text only
(unlike automake where we previously pulled these files from as a
backup). This PR adds `gnuconfig` as an unconditional build dependency
for arm and power archs.
In case the user needs a system version of config.sub and config.guess,
they are free to mark `gnuconfig` as an external package with the prefix
pointing to the directory containing the config files:
```yaml
gnuconfig:
externals:
- spec: gnuconfig@master
prefix: /tmp/tmp.ooBlkyAKdw/lol
buildable: false
```
Apart from that, this PR gives some better instructions for users when
replacing config files goes wrong.
* Mock needs this package too now, because autotools adds a depends_on
* Add documentation
* Make patch_config_files a prop, fix the docs, add integrations tests
* Make macOS happy
This will allow a user to (from anywhere a Spec is parsed including both name and version) refer to a git commit in lieu of
a package version, and be able to make comparisons with releases in the history based on commits (or with other commits). We do this by way of:
- Adding a property, is_commit, to a version, meaning I can always check if a version is a commit and then change some action.
- Adding an attribute to the Version object which can lookup commits from a git repo and find the last known version before that commit, and the distance
- Construct new Version comparators, which are tuples. For normal versions, they are unchanged. For commits with a previous version x.y.z, d commits away, the comparator is (x, y, z, '', d). For commits with no previous version, the comparator is ('', d) where d is the distance from the first commit in the repo.
- Metadata on git commits is cached in the misc_cache, for quick lookup later.
- Git repos are cached as bare repos in `~/.spack/git_repos`
- In both caches, git repo urls are turned into file paths within the cache
If a commit cannot be found in the cached git repo, we fetch from the repo. If a commit is found in the cached metadata, we do not recompare to newly downloaded tags (assuming repo structure does not change). The cached metadata may be thrown out by using the `spack clean -m` option if you know the repo structure has changed in a way that invalidates existing entries. Future work will include automatic updates.
# Finding previous versions
Spack will search the repo for any tags that match the string of a version given by the `version` directive. Spack will also search for any tags that match `v + string` for any version string. Beyond that, Spack will search for tags that match a SEMVER regex (i.e., tags of the form x.y.z) and interpret those tags as valid versions as well. Future work will increase the breadth of tags understood by Spack
For each tag, Spack queries git to determine whether the tag is an ancestor of the commit in question or not. Spack then sorts the tags that are ancestors of the commit by commit-distance in the repo, and takes the nearest ancestor. The version represented by that tag is listed as the previous version for the commit.
Not all commits will find a previous version, depending on the package workflow. Future work may enable more tangential relationships between commits and versions to be discovered, but many commits in real world git repos require human knowledge to associate with a most recent previous version. Future work will also allow packages to specify commit/tag/version relationships manually for such situations.
# Version comparisons.
The empty string is a valid component of a Spack version tuple, and is in fact the lowest-valued component. It cannot be generated as part of any valid version. These two characteristics make it perfect for delineating previous versions from distances. For any version x.y.z, (x, y, z, '', _) will be less than any "real" version beginning x.y.z. This ensures that no distance from a release will cause the commit to be interpreted as "greater than" a version which is not an ancestor of it.

This is a major rework of Spack's core core `spec.yaml` metadata format. It moves from `spec.yaml` to `spec.json` for speed, and it changes the format in several ways. Specifically:
1. The spec format now has a `_meta` section with a version (now set to version `2`). This will simplify major changes like this one in the future.
2. The node list in spec dictionaries is no longer keyed by name. Instead, it is a list of records with no required key. The name, hash, etc. are fields in the dictionary records like any other.
3. Dependencies can be keyed by any hash (`hash`, `full_hash`, `build_hash`).
4. `build_spec` provenance from #20262 is included in the spec format. This means that, for spliced specs, we preserve the *full* provenance of how to build, and we can reproduce a spliced spec from the original builds that produced it.
**NOTE**: Because we have switched the spec format, this PR changes Spack's hashing algorithm. This means that after this commit, Spack will think a lot of things need rebuilds.
There are two major benefits this PR provides:
* The switch to JSON format speeds up Spack significantly, as Python's builtin JSON implementation is orders of magnitude faster than YAML.
* The new Spec format will soon allow us to represent DAGs with potentially multiple versions of the same dependency -- e.g., for build dependencies or for compilers-as-dependencies. This PR lays the necessary groundwork for those features.
The old `spec.yaml` format continues to be supported, but is now considered a legacy format, and Spack will opportunistically convert these to the new `spec.json` format.
* tests: make `spack url [stats|summary]` work on mock packages
Mock packages have historically had mock hashes, but this means they're also invalid
as far as Spack's hash detection is concerned.
- [x] convert all hashes in mock package to md5 or sha256
- [x] ensure that all mock packages have a URL
- [x] ignore some special cases with multiple VCS fetchers
* url stats: add `--show-issues` option
`spack url stats` tells us how many URLs are using what protocol, type of checksum,
etc., but it previously did not tell us which packages and URLs had the issues. This
adds a `--show-issues` option to show URLs with insecure (`http`) URLs or `md5` hashes
(which are now deprecated by NIST).
This commit adds a regression test for version selection
with preferences in `packages.yaml`. Before PR 25585 we
used negative weights in a minimization to select the
optimal version. This may lead to situations where a
dependency may make the version score of dependents
"better" if it is preferred in packages.yaml.
Preferred providers had a non-zero weight because in an earlier formulation of the logic program that was needed to prefer external providers over default providers. With the current formulation for externals this is not needed anymore, so we can give a weight of zero to both default choices and providers that are externals. _Using zero ensures that we don't introduce any drift towards having less providers, which was happening when minimizing positive weights_.
Modifications:
- [x] Default weight for providers starts at 0 (instead of 10, needed before to prefer externals)
- [x] Rules to compute the `provider_weight` have been refactored. There are multiple possible weights for a given `Virtual`. Only one gets selected by the solver (the one that minimizes the objective function).
- [x] `provider_weight` are now accounting for each different `Virtual`. Before there was a single weight per provider, even if the package was providing multiple virtuals.
* Give preferred providers a weight of zero
Preferred providers had a non-zero weight because in an earlier
formulation of the logic program that was needed to prefer
external providers over default providers.
With the current formulation for externals this is not needed anymore,
so we can give a weight of zero to default choices. Using zero
ensures that we don't introduce any drift towards having
less providers, which was happening when minimizing positive weights.
* Simplify how we compute weights for providers
Rewrite rules so that specific events (i.e. being
an external) unlock the possibility to use certain
weights. The weight being considered is then selected
by the minimization process to be the one that gives
the best score.
* Allow providers to have different weights for different virtuals
Before this change we didn't differentiate providers based on
the virtual they provide, which meant that packages providing
more than one virtual had nonetheless a single weight.
With this change there will be a weight per virtual.
* fix remaining flake8 errors
* imports: sort imports everywhere in Spack
We enabled import order checking in #23947, but fixing things manually drives
people crazy. This used `spack style --fix --all` from #24071 to automatically
sort everything in Spack so PR submitters won't have to deal with it.
This should go in after #24071, as it assumes we're using `isort`, not
`flake8-import-order` to order things. `isort` seems to be more flexible and
allows `llnl` mports to be in their own group before `spack` ones, so this
seems like a good switch.
This PR adds a context manager that permit to group the common part of a `when=` argument and add that to the context:
```python
class Gcc(AutotoolsPackage):
with when('+nvptx'):
depends_on('cuda')
conflicts('@:6', msg='NVPTX only supported in gcc 7 and above')
conflicts('languages=ada')
conflicts('languages=brig')
conflicts('languages=go')
```
The above snippet is equivalent to:
```python
class Gcc(AutotoolsPackage):
depends_on('cuda', when='+nvptx')
conflicts('@:6', when='+nvptx', msg='NVPTX only supported in gcc 7 and above')
conflicts('languages=ada', when='+nvptx')
conflicts('languages=brig', when='+nvptx')
conflicts('languages=go', when='+nvptx')
```
which needs a repetition of the `when='+nvptx'` argument. The context manager might help improving readability and permits to group together directives related to the same semantic aspect (e.g. all the directives needed to model the behavior of `gcc` when `+nvptx` is active).
Modifications:
- [x] Added a `when` context manager to be used with package directives
- [x] Add unit tests and documentation for the new feature
- [x] Modified `cp2k` and `gcc` to show the use of the context manager
This commit fixes a subtle bug that may occur when
a package is a "possible_provider" of a virtual but
no "provides_virtual" can be deduced. In that case
the cardinality constraint on "provides_virtual"
may arbitrarily assign a package the role of provider
even if the constraints for it to be one are not fulfilled.
The fix reworks the logic around three concepts:
- "possible_provider": a package may provide a virtual if some constraints are met
- "provides_virtual": a package meet the constraints to provide a virtual
- "provider": a package selected to provide a virtual
Spack packages can now fetch versions from CVS repositories. Note
this fetch mechanism is unsafe unless using :extssh:. Most public
CVS repositories use an insecure protocol implemented as part of CVS.
Here we are adding an install_times.json into the spack install metadata folder.
We record a total, global time, along with the times for each phase. The type
of phase or install start / end is included (e.g., build or fail)

Minimizing compiler mismatches in the DAG and preferring newer
versions of packages are now higher priority than trying to use as
many default values as possible in multi-valued variants.
fixes#22351
The ASP-based solver now accounts for the presence
in the DAG of deprecated versions and tries to minimize
their number at highest priority.
Variants explicitly set in an abstract root spec are considered
as defaults for the package they refer to, and they override
what is in packages.yaml and in package.py. This is relevant
only for multi-valued variants, where a constraint may extend
an already default value.
fixes#22565
This change enforces the uniqueness of the version_weight
atom per node(Package) in the DAG. It does so by applying
FTSE and adding an extra layer of indirection with the
possible_version_weight/2 atom.
Before this change it may have happened that for the same
node two different version_weight/2 were in the answer set,
each of which referred to a different spec with the same
version, and their weights would sum up.
This lead to unexpected result like preferring to build a
new version of an external if the external version was
older.
* ASP-based solver: avoid adding values to variants when they're set
fixes#22533fixes#21911
Added a rule that prevents any value to slip in a variant when the
variant is set explicitly. This is relevant for multi-valued variants,
in particular for those that have disjoint sets of values.
* Ensure disjoint sets have a clear semantics for external packages
When using an external package with the old concretizer, all
dependencies of that external package were severed. This was not
performed bidirectionally though, so for an external package W with
a dependency on Z, if some other package Y depended on Z, Z could
still pull properties (e.g. compiler) from W since it was not
severed as a parent dependency.
This performs the severing bidirectionally, and adds tests to
confirm expected behavior when using config from DAG-adjacent
packages during concretization.
* Spec.splice feature
Construct a new spec with a dependency swapped out. Currently can only swap dependencies of the same name, and can only apply to concrete specs.
This feature is not yet attached to any install functionality, but will eventually allow us to "rewire" a package to depend on a different set of dependencies.
Docstring is reformatted for git below
Splices dependency "other" into this ("target") Spec, and return the result as a concrete Spec.
If transitive, then other and its dependencies will be extrapolated to a list of Specs and spliced in accordingly.
For example, let there exist a dependency graph as follows:
T
| \
Z<-H
In this example, Spec T depends on H and Z, and H also depends on Z.
Suppose, however, that we wish to use a differently-built H, known as H'. This function will splice in the new H' in one of two ways:
1. transitively, where H' depends on the Z' it was built with, and the new T* also directly depends on this new Z', or
2. intransitively, where the new T* and H' both depend on the original Z.
Since the Spec returned by this splicing function is no longer deployed the same way it was built, any such changes are tracked by setting the build_spec to point to the corresponding dependency from the original Spec.

* Improve error message for inconsistencies in package.py
Sometimes directives refer to variants that do not exist.
Make it such that:
1. The name of the variant
2. The name of the package which is supposed to have
such variant
3. The name of the package making this assumption
are all printed in the error message for easier debugging.
* Add unit tests
Keep spack.store.store and spack.store.db consistent in unit tests
* Remove calls to monkeypatch for spack.store.store and spack.store.db:
tests that used these called one or the other, which lead to
inconsistencies (the tests passed regardless but were fragile as a
result)
* Fixtures making use of monkeypatch with mock_store now use the
updated use_store function, which sets store.store and store.db
consistently
* subprocess_context.TestState now transfers the serializes and
restores spack.store.store (without the monkeypatch changes this
would have created inconsistencies)
* sbang pushed back to callers;
star moved to util.lang
* updated unit test
* sbang test moved; local tests pass

fixes#20040
Matching compilers among nodes has been prioritized
in #20020. Selection of default variants has been
tuned in #20182. With this setup there is no need
to have an ad-hoc rule for external packages. On
the contrary it should be removed to prefer having
default variant values over more external nodes in
the DAG.
refers #20040
Before this PR optimization rules would have selected default
providers at a higher priority than default variants. Here we
swap this priority and we consider variants that are forced by
any means (root spec or spec in depends_on clause) the same as
if they were with a default value.
This prevents the solver from avoiding expected configurations
just because they contain directives like:
depends_on('pkg+foo')
and `+foo` is not the default variant value for pkg.
fixes#19981
This commit adds support for target ranges in directives,
for instance:
conflicts('+foo', when='target=x86_64:,aarch64:')
If any target in a spec body is not a known target the
following clause will be emitted:
node_target_satisfies(Package, TargetConstraint)
when traversing the spec and a definition of
the clause will then be printed at the end similarly
to what is done for package and compiler versions.
fixes#20019
Before this modification having a newer version of a node came
at higher priority in the optimization than having matching
compilers. This could result in unexpected configurations for
packages with conflict directives on compilers of the type:
conflicts('%gcc@X.Y:', when='@:A.B')
where changing the compiler for just that node is preferred to
lower the node version to less than 'A.B'. Now the priority has
been switched so the solver will try to lower the version of the
nodes in question before changing their compiler.
refers #20079
Added docstrings to 'concretize' and 'concretized' to
document the format for tests.
Added tests for the activation of test dependencies.
refers #20040
This modification emits rules like:
provides_virtual("netlib-lapack","blas") :- variant_value("netlib-lapack","external-blas","False").
for packages that provide virtual dependencies conditionally instead
of a fact that doesn't account for the condition.
Users can add test() methods to their packages to run smoke tests on
installations with the new `spack test` command (the old `spack test` is
now `spack unit-test`). spack test is environment-aware, so you can
`spack install` an environment and then run `spack test run` to run smoke
tests on all of its packages. Historical test logs can be perused with
`spack test results`. Generic smoke tests for MPI implementations, C,
C++, and Fortran compilers as well as specific smoke tests for 18
packages.
Inside the test method, individual tests can be run separately (and
continue to run best-effort after a test failure) using the `run_test`
method. The `run_test` method encapsulates finding test executables,
running and checking return codes, checking output, and error handling.
This handles the following trickier aspects of testing with direct
support in Spack's package API:
- [x] Caching source or intermediate build files at build time for
use at test time.
- [x] Test dependencies,
- [x] packages that require a compiler for testing (such as library only
packages).
See the packaging guide for more details on using Spack testing support.
Included is support for package.py files for virtual packages. This does
not change the Spack interface, but is a major change in internals.

This commit address the case of concretizing a root spec with a
transitive conditional dependency on a virtual package, provided
by an external. Before these modifications default variant values
for the dependency bringing in the virtual package were not
respected, and the external package providing the virtual was added
to the DAG.
The issue stems from two facts:
- Selecting a provider has higher precedence than selecting default variants
- To ensure that an external is preferred, we used a negative weight
To solve it we shift all the providers weight so that:
- External providers have a weight of 0
- Non external provider have a weight of 10 or more
Using a weight of zero for external providers is such that having
an external provider, if present, or not having a provider at all
has the same effect on the higher priority minimization.
Also fixed a few minor bugs in concretize.lp, that were causing
spurious entries in the final answer set.
Cleaned concretize.lp from leftover rules.
This commit introduces a new rule:
real_node(Package) :- not external(Package), node(Package).
that permits to distinguish between an external node and a
real node that shouldn't trim dependency. It solves the
case of concretizing ninja with an external Python.
As reported, conflicts with compiler ranges were not treated
correctly. This commit adds tests to verify the expected behavior
for the new concretizer.
The new rules to enforce a correct behavior involve:
- Adding a rule to prefer the compiler selected for
the root package, if no other preference is set
- Give a strong negative weight to compiler preferences
expressed in packages.yaml
- Maximize on compiler AND compiler version match
As of #13100, Spack installs the dependencies of a _single_ spec in parallel.
Environments, when installed, can only get parallelism from each individual
spec, as they're installed in order. This PR makes entire environments build
in parallel by extending Spack's package installer to accept multiple root
specs. The install command and Environment class have been updated to use
the new parallel install method.
The specs and kwargs for each *uninstalled* package (when not force-replacing
installations) of an environment are collected, passed to the `PackageInstaller`,
and processed using a single build queue.
This introduces a `BuildRequest` class to track install arguments, and it
significantly cleans up the code used to track package ids during installation.
Package ids in the build queue are now just DAG hashes as you would expect,
Other tasks:
- [x] Finish updating the unit tests based on `PackageInstaller`'s use of
`BuildRequest` and the associated changes
- [x] Change `environment.py`'s `install_all` to use the `PackageInstaller` directly
- [x] Change the `install` command to leverage the new installation process for multiple specs
- [x] Change install output messages for external packages, e.g.:
`[+] /usr` -> `[+] /usr (external bzip2-1.0.8-<dag-hash>`
- [x] Fix incomplete environment install's view setup/update and not confirming all
packages are installed (?)
- [x] Ensure externally installed package dependencies are properly accounted for in
remaining build tasks
- [x] Add tests for coverage (if insufficient and can identity the appropriate, uncovered non-comment lines)
- [x] Add documentation
- [x] Resolve multi-compiler environment install issues
- [x] Fix issue with environment installation reporting (restore CDash/JUnit reports)

* autotools: add attribute to delete libtool archives .la files
According to Autotools Mythbuster (https://autotools.io/libtool/lafiles.html)
libtool archive files are mostly vestigial, but they might create issues
when relocating binary packages as shown in #18694.
For GCC specifically, most distributions remove these files with
explicit commands:
https://git.stg.centos.org/rpms/gcc/blob/master/f/gcc.spec#_1303
Considered all of that, this commit adds an easy way for each
AutotoolsPackage to remove every .la file that has been installed.
The default, for the time being, is to maintain them - to be consistent
with what Spack was doing previously.
* autotools: delete libtool archive files by default
Following review this commit changes the default for
libtool archive files deletion and adds test to verify
the behavior.
The YAML config for paths and modules of external packages has
changed: the new format allows a single spec to load multiple
modules. Spack will automatically convert from the old format
when reading the configs (the updates do not add new essential
properties, so this change in Spack is backwards-compatible).
With this update, Spack cannot modify existing configs/environments
without updating them (e.g. “spack config add” will fail if the
configuration is in a format that predates this PR). The user is
prompted to do this explicitly and commands are provided. All
config scopes can be updated at once. Each environment must be
updated one at a time.

Because of the way abstract variants are implemented, the following
spec matrix does not work as intended:
```
matrix:
- [foo]
- [bar=a, bar=b]
exclude:
- bar=a
```
because abstract variants always satisfy any variant of the same
name, regardless of values.
This PR converts abstract variants to whatever their appropriate
type is before running satisfaction checks for the excludes clause
in a matrix.
fixes#16841
This change also adds a code path through the spack ci pipelines
infrastructure which supports PR testing on the Spack repository.
Gitlab pipelines run as a result of a PR (either creation or pushing
to a PR branch) will only verify that the packages in the environment
build without error. When the PR branch is merged to develop,
another pipeline will run which results in the generated binaries
getting pushed to the binary mirror.
Add a `spack external find` command that tries to populate
`packages.yaml` with external packages from the user's `$PATH`. This
focuses on finding build dependencies. Currently, support has only been
added for `cmake`.
For a package to be discoverable with `spack external find`, it must define:
* an `executables` class attribute containing a list of
regular expressions that match executable names.
* a `determine_spec_details(prefix, specs_in_prefix)` method
Spack will call `determine_spec_details()` once for each prefix where
executables are found, passing in the path to the prefix and the path to
all found executables. The package is responsible for invoking the
executables and figuring out what type of installation(s) are in the
prefix, and returning one or more specs (each with version, variants or
whatever else the user decides to include in the spec).
The found specs and prefixes will be added to the user's `packages.yaml`
file. Providing the `--not-buildable` option will mark all generated
entries in `packages.yaml` as `buildable: False`
Update compiler config with bootstrapped compiler when it was already installed and added config defaults to code so mutable_config test fixture works.
* SourceForge: Mirror Mixin
Add a mixing class for direct `CNAME`s to sourceforge mirrors.
Since the main gateway servers are often down, this could reduce
timeouts and fetch errors for sourceforge.net hosted software.
* SourceForge: unspectacular mirror replacement
add mirrors to all sourceforge packages with trivial
download logic.
tested fetch of latest version of each of these packages
with various mirrors before committing.
* SourceForge: xz
the author homepage is chronocially overrun and this is the offical
upload with many mirrors.
Add a 'define_from_variant` helper function to CMake-based Spack
packages to convert package variants into CMake arguments. For
example:
args.append('-DFOO=%s' % ('ON' if '+foo' in self.spec else 'OFF'))
can be replaced with:
args.append(self.define_from_variant('foo'))
The following conversions are handled automatically:
* Flag variants will be converted to CMake booleans
* Multivalued variants will be converted to semicolon-separated strings
* Other variant values are converted to CMake string arguments
This also adds a 'define' helper method to convert any variable to
a CMake argument. It has the same conversion rules as
'define_from_variant' (but operates directly on values rather than
requiring the user to supply the name of a package variant).
PR #15212 added a new connect_timeout option that can be overridden
using fetch_options but had to specified per-version. This adds a new
per-package variable that can be used to override fetch_options for
all versions in the package. This includes connect_timeout as well
as 'cookie' (e.g. for the jdk package).
Packages can combine package-level fetch_options with per-version
fetch_options, in which case the version fetch_options completely
override the package-level fetch_options.
This commit includes tests for the added behavior.
* add --skip-unstable-versions option to 'spack mirror create' which skips sources/resource for packages if their version is not stable (i.e. if they are the head of a git branch rather than a fixed commit)
* '--skip-unstable-versions' should skip all VCS sources/resources, not just those which are not cachable
The hashing logic looks for function calls that are Spack directives.
It expects that when a Spack directive is used that it is referenced
directly by name, and that the directive function is not itself
retrieved by calling another function. When the hashing logic
encountered a function call where the function was determined
dynamically, it would fail (attempting to access a name attribute
that does not happen to exist in this case).
This updates the hashing logic to filter out function calls where the
function is determined dynamically when looking for uses of Spack
directives.
Fixes#9394Closes#13217.
## Background
Spack provides the ability to enable/disable parallel builds through two options: package `parallel` and configuration `build_jobs`. This PR changes the algorithm to allow multiple, simultaneous processes to coordinate the installation of the same spec (and specs with overlapping dependencies.).
The `parallel` (boolean) property sets the default for its package though the value can be overridden in the `install` method.
Spack's current parallel builds are limited to build tools supporting `jobs` arguments (e.g., `Makefiles`). The number of jobs actually used is calculated as`min(config:build_jobs, # cores, 16)`, which can be overridden in the package or on the command line (i.e., `spack install -j <# jobs>`).
This PR adds support for distributed (single- and multi-node) parallel builds. The goals of this work include improving the efficiency of installing packages with many dependencies and reducing the repetition associated with concurrent installations of (dependency) packages.
## Approach
### File System Locks
Coordination between concurrent installs of overlapping packages to a Spack instance is accomplished through bottom-up dependency DAG processing and file system locks. The runs can be a combination of interactive and batch processes affecting the same file system. Exclusive prefix locks are required to install a package while shared prefix locks are required to check if the package is installed.
Failures are communicated through a separate exclusive prefix failure lock, for concurrent processes, combined with a persistent store, for separate, related build processes. The resulting file contains the failing spec to facilitate manual debugging.
### Priority Queue
Management of dependency builds changed from reliance on recursion to use of a priority queue where the priority of a spec is based on the number of its remaining uninstalled dependencies.
Using a queue required a change to dependency build exception handling with the most visible issue being that the `install` method *must* install something in the prefix. Consequently, packages can no longer get away with an install method consisting of `pass`, for example.
## Caveats
- This still only parallelizes a single-rooted build. Multi-rooted installs (e.g., for environments) are TBD in a future PR.
Tasks:
- [x] Adjust package lock timeout to correspond to value used in the demo
- [x] Adjust database lock timeout to reduce contention on startup of concurrent
`spack install <spec>` calls
- [x] Replace (test) package's `install: pass` methods with file creation since post-install
`sanity_check_prefix` will otherwise error out with `Install failed .. Nothing was installed!`
- [x] Resolve remaining existing test failures
- [x] Respond to alalazo's initial feedback
- [x] Remove `bin/demo-locks.py`
- [x] Add new tests to address new coverage issues
- [x] Replace built-in package's `def install(..): pass` to "install" something
(i.e., only `apple-libunwind`)
- [x] Increase code coverage
Fixes#10019
If multiple instances of a package were installed in a single
instance of Spack, and they differed in terms of dependencies, then
"spack find" would not distinguish specs based on their dependencies.
For example if two instances of X were installed, one with Y and one
with Z, then "spack find X ^Y" would display both instances of X.
Users can now list mirrors of the main url in packages.
- [x] Instead of just a single `url` attribute, users can provide a list (`urls`) in the package, and these will be tried by in order by the fetch strategy.
- [x] To handle one of the most common mirror cases, define a `GNUMirrorPackage` mixin to handle all the standard GNU mirrors. GNU packages can set `gnu_mirror_path` to define the path within a mirror, and the mixin handles setting up all the requisite GNU mirror URLs.
- [x] update all GNU packages in `builtin` to use the `GNUMirrorPackage` mixin.
- Add an optional argument so that `possible_dependencies()` will report
missing dependencies.
- Add a test to ensure it works.
- Ignore missing dependencies in `possible_dependencies()` by default.
* when constructing package hash, default to including a method in the content hash if we can't determine whether it would be included by examining the AST
* add a test for updated content-hash calculations
* refactor content hash tests to eliminate repeated lines
* apply strict constraint checks for patches, otherwise Spack may incorrectly treat a version range constraint as satisfied when mixing x.y and x.y.z versions
* add mixed version checks to version comparison tests
Rename the `spack diy` command to `spack dev-build` to make the use case clearer.
The `spack diy` command has some useful functionality for developers using Spack to build their dependencies and configure/build/install the code they are developing. Developers do not notice it, partly because of the obscure name.
The `spack dev-build` command has a `-u/--until PHASE` option to stop after a given phase of the build. This can be used to configure your project, run cmake on your project, or similarly stop after any stage of the build the user wants. These options are analogous to the existing `spack configure` and `spack build` commands, but for developer builds.
To unify the syntax, we have deprecated the `spack configure` and `spack build` commands, and added a `-u/--until PHASE` option to the `spack install` command as well.
The functionality in `spack dev-build` (specifically `spack dev-build -u cmake`) may be able to supersede the `spack setup` command, but this PR does not deprecate that command as that will require slightly more thought.
This PR ensures that environment activation sets all environment variables set by the equivalent `module load` operations, except that the spec prefixes are "rebased" to the view associated with the environment.
Currently, Spack blindly adds paths relative to the environment view root to the user environment on activation. Issue #12731 points out ways in which this behavior is insufficient.
This PR changes that behavior to use the `setup_run_environment` logic for each package to augment the prefix inspections (as in Spack's modulefile generation logic) to ensure that all necessary variables are set to make use of the packages in the environment.
See #12731 for details on the previous problems in behavior.
This PR also updates the `ViewDescriptor` object in `spack.environment` to have a `__contains__` method. This allows for checks like `if spec in self.default_view`. The `__contains__` operator for `ViewDescriptor` objects checks whether the spec satisfies the filters of the View descriptor, not whether the spec is already linked into the underlying `FilesystemView` object.
Dotkit is being used only at a few sites and has been deprecated on new
machines. This commit removes all the code that provide support for the
generation of dotkit module files.
A new validator named "deprecatedProperties" has been added to the
jsonschema validators. It permits to prompt a warning message or exit
with an error if a property that has been marked as deprecated is
encountered.
* Removed references to dotkit in the docs
* Removed references to dotkit in setup-env-test.sh
* Added a unit test for the 'deprecatedProperties' schema validator
- Fix trailing whitespace missed by the bug described in #12755.
- Fix other style issues that have crept in over time (this can happen
when flake8 adds new checks with new versions)
This adds a special package type to Spack which is used to aggregate
a set of packages that a user might commonly install together; it
does not include any source code itself and does not require a
download URL like other Spack packages. It may include an 'install'
method to generate scripts, and Spack will run post-install hooks
(including module generation).
* Add new BundlePackage type
* Update the Xsdk package to be a BundlePackage and remove the
'install' method (previously it had a noop install method)
* "spack create --template" now takes "bundle" as an option
* Rename cmd_create_repo fixture to "mock_test_repo" and relocate it
to shared pytest fixtures
* Add unit tests for BundlePackage behavior
- We don't currently make enough use of the maintainers field on
packages, though we could use it to assign reviews.
- add a command that allows maintainers to be queried
- can ask who is maintaining a package or packages
- can ask what packages users are maintaining
- can list all maintained or unmaintained packages
- add tests for the command
- `parse_anonymous_spec()` is a vestige of the days when Spack didn't
support nameless specs. We don't need it anymore because now we can
write Spec() for a spec that will match anything, and satisfies()
semantics work properly for anonymous specs.
- Delete `parse_anonymous_spec()` and replace its uses with simple calls
to the Spec() constructor.
- make then handling of when='...' specs in directives more consistent.
- clean up Spec.__contains__()
- refactor directives and tests slightly to accommodate the change.
This PR implements several refactors requested in #11373, specifically:
- Config scopes are used to handle builtin defaults, command line overrides
and package overrides (`parallel=False`)
- `Package.make_jobs` attribute has been removed; `make_jobs` remains
as a module-scope variable in the build environment.
- The use of the argument `-j` has been rationalized across commands
- move '-j'/'--jobs' argument into `spack.cmd.common.arguments`
- Add unit tests to check that setting parallel jobs works as expected
- add new test to ensure that build job setting is isolated to each build
- Fix packages that used `Package.make_jobs` (i.e. `bazel`)
* extend Version class so that 2.0 > 1.develop > 1.1
* add concretization tests, with preferences and preferred version.
* add master, head, trunk as develop-like versions, develop > master > head > trunk
* update documentation on version comparison
* initial work to make use of an 'upstream' spack installation: this uses the DB of the upstream installation to check if a package is installed
* need to query upstream dbs when adding new record to local db
* prevent reindexing upstream DBs
* set prefix on specs read from DB based on path stored in install record
* check that Spack does not install packages that are recorded as installed in an upstream db
* externals do not add their path to install records - need to use 'external_path' to get path of upstream externals
* views need to check for upstream installations when linking metadata
* package and spec now calculate upstream installation properties on-demand themselves rather than depending on concretization to set these properties up-front. The added tests for upstream installations don't work with this new strategy so they need to be updated
* only refresh modules for local specs (not those in upstream packages); optionally generate local module files for packages installed upstream
* when a user tries to locate a module file for a package installed upstream, tell them to use the upstream spack instance to locate it
* support recursive upstream databases (allow upstream databases to use their own upstream databases)
* separate upstream config into separate file with its own schema; each entry now also includes a name
* metadata_dir is no longer customizable on a per-instance basis for YamlDirectoryLayout
* treat metadata_dir as an instance variable but dont set it from kwargs; this follows several other hardcoded variables which must be consistent between upstream and downstream DBs. Also update DirectoryLayout.metadata_path to work entirely with Spec.prefix, since Spec.prefix is set from the DB when available (so metadata_path was duplicating that logic)
Allow customizing views with Spec-formatted directory structure
Allow views to specify projections that are more complicated than
merging every package into a single shared prefix. This will allow
sites to configure a view for the way they want to present packages
to their users; for example this can be used to create a prefix for
each package but omit the DAG hash from the path.
This includes a new YAML format file for specifying the simplified
prefix for a spec in a view. This configuration allows the use of
different prefix formats for different specs (i.e. specs depending
on MPI can include the MPI implementation in the prefix).
Documentation on usage of the view projection configuration is
included.
Depending on the projection configuration, paths are not guaranteed
to be unique and it may not be possible to add multiple installs of
a package to a view.
This enforces conventions that allow for correct handling of
multi-valued variants where specifying no value is an option,
and adds convenience functionality for specifying multi-valued
variants with conflicting sets of values. This also adds a notion
of "feature values" for variants, which are those that are understood
by the build system (e.g. those that would appear as configure
options). In more detail:
* Add documentation on variants to the packaging guide
* Forbid usage of '' or None as a possible variant value, in
particular as a default. To indicate choosing no value, the user
must explicitly define an option like 'none'. Without this,
multi-valued variants with default set to None were not parsable
from the command line (Fixes#6314)
* Add "disjoint_sets" function to support the declaration of
multi-valued variants with conflicting sets of options. For example
a variant "foo" with possible values "a", "b", and "c" where "c"
is exclusive of the other values ("foo=a,b" and "foo=c" are
valid but "foo=a,c" is not).
* Add "any_combination_of" function to support the declaration of
multi-valued variants where it is valid to choose none of the
values. This automatically defines "none" as an option (exclusive
with all other choices); this value does not appear when iterating
over the variant's values, for example in "with_or_without" (which
constructs autotools option strings from variant values).
* The "disjoint_sets" and "any_combination_of" methods return an
object which tracks the possible values. It is also possible to
indicate that some of these values do not correspond to options
understood by the package's build system, such that methods like
"with_or_without" will not define options for those values (this
occurs automatically for "none")
* Add documentation for usage of new functions for specifying
multi-valued variants
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
- dependency patching test didn't attempt to apply patches; just to see
whether they were on the spec.
- it applies the patch now and verifies that that patch was applied.
- Previously, Spack didn't check the arguments you put in version()
directives.
- So, you could do something like this, where there are arguments for a
URL fetcher AND for a git fetcher:
version('1.0', md5='abc123', git='https://foo.bar', commit='feda2343')
- Now, we check the arguments before constructing a fetcher, to ensure
that each package has *only* arguments for a single type of fetcher.
- Also added `test_package_version_consistency()` to the `package_sanity`
test, so that all builtin packages are required to have valid
`version()` directives.
- packagers can specify two top-level fetch URLs if one is `url`
- e.g., `url` and `git` or `url` and `svn`
- allow only one VCS fetcher so we can differentiate between URL and VCS.
- also clean up fetcher logic and class structure
- Packages can remove the top-level `url` attribute and still work
- These are now legal:
- Packages with *only* version-specific URLs (even with gaps)
- Packages with a top-level git/hg/svn attribute and `version`
directives for that.
- If a package has both a top-level hg/git/svn attribute AND a top-level
url attribute, the url attribute takes precedence.
- This changes `get_checksums_for_versions` to generate code that uses an
explicit `sha256` argument instead if the bare `md5` hash we used to
generate.
- also use a generic digest parameter for the `version` directive, rather
than a specific `md5` parameter.
Fixes#8036
Before this PR Package.installed was returning True if the spec prefix
existed, without checking the DB. This is wrong for external packages,
whose prefix exists before being registered into the DB. Now the property
checks for both the prefix and a DB entry.
When a user specifies a URL for a specific version of a package, Spack originally
would use that URL for all newer versions of the package. This behavior has
proven to be generally more harmful than useful, so this PR removes the feature
such that a version-specific URL override affects only that version.
Fixes#2781
This PR introduces a new attribute for packages called
`archive_files`, which designates files that should be saved from
a package build (e.g. the config.log generated during autotools
builds).
The attribute contains a list of glob expressions; Any file that
matches will be archived in the `<prefix>/.spack/archived-files`
directory. Errors that occur when archiving files are collected and
reported in a file named `<prefix>/.spack/archived-files/errors.txt`.
`AutotoolsPackage` and `CMakePackage` provide a sensible default
override for this attribute.
* Cleaned up JUnit report generation on install
The generation of a JUnit report was previously part of the install
command. This commit factors the logic into its own module, and uses
a template for the generation of the report.
It also improves report generation, that now can deal with multiple
specs installed at once. Finally, extending the list of supported
formats is much easier than before, as it entails just writing a
new template.
* Polished report generation + added tests for failures and errors
The generation of a JUnit report has been polished, so that the
stacktrace is correctly displayed with Jenkins JUnit plugin. Standard
error is still not used.
Added unit tests to cover for installation failures and installation
errors.
- Tests use a session-scoped mock stage directory so as not to interfere
with the real install.
- Every test is forced to clean up after itself with an additional check.
We now automatically assert that no new files have been added to
`spack.stage_path` during each test.
- This means that tests that fail installs now need to clean up their
stages, but in all other cases the check is useful.
* edits to address issues where spack concretization attempts to set properties on already-installed specs
* most added checks only need to check if the spec is concrete; they dont also need to check if the package is installed
* add test to ensure that patches are not applied to an installed spec
* add test to ensure that an error is detected when a dependent requests a dependency constraint which conflicts with a requested installed dependency
- A package can depend on a special patched version of its dependencies.
- The `Spec` YAML (and therefore the hash) now includes the sha256 of
the patch in the `Spec` YAML, which changes its hash.
- The special patched version will be built separately from a "vanilla"
version of the same package.
- This allows packages to maintain patches on their dependencies
without affecting either the dependency package or its dependents.
This could previously be accomplished with special variants, but
having to add variants means the hash of the dependency changes
frequently when it really doesn't need to. This commit allows the
hash to change *just* for dependencies that need patches.
- Patching dependencies shouldn't be the common case, but some packages
(qmcpack, hpctoolkit, openspeedshop) do this kind of thing and it
makes the code structure mirror maintenance responsibilities.
- Note that this commit means that adding or changing a patch on a
package will change its hash. This is probably what *should* happen,
but we haven't done it so far.
- Only applies to `patch()` directives; `package.py` files (and their
`patch()` functions) are not hashed, but we'd like to do that in the
future.
- The interface looks like this: `depends_on()` can optionally take a
patch directive or a list of them:
depends_on(<spec>,
patches=patch(..., when=<cond>),
when=<cond>)
# or
depends_on(<spec>,
patches=[patch(..., when=<cond>),
patch(..., when=<cond>)],
when=<cond>)
- Previously, the `patch()` directive only took an `md5` parameter. Now
it only takes a `sha256` parameter. We restrict this because we want
to be consistent about which hash is used in the `Spec`.
- A side effect of hashing patches is that *compressed* patches fetched
from URLs now need *two* checksums: one for the downloaded archive and
one for the content of the patch itself. Patches fetched uncompressed
only need a checksum for the patch. Rationale:
- we include the content of the *patch* in the spec hash, as that is
the checksum we can do consistently for patches included in Spack's
source and patches fetched remotely, both compressed and
uncompressed.
- we *still* need the patch of the downloaded archive, because we want
to verify the download *before* handing it off to tar, unzip, or
another decompressor. Not doing so is a security risk and leaves
users exposed to any arbitrary code execution vulnerabilities in
compression tools.
* Module files now are generated using a template engine refers #2902#3173
jinja2 has been hooked into Spack.
The python module `modules.py` has been splitted into several modules
under the python package `spack/modules`. Unit tests stressing module
file generation have been refactored accordingly.
The module file generator for Lmod has been extended to multi-providers
and deeper hierarchies.
* Improved the support for templates in module files.
Added an entry in `config.yaml` (`template_dirs`) to list all the
directories where Spack could find templates for `jinja2`.
Module file generators have a simple override mechanism to override
template selection ('modules.yaml' beats 'package.py' beats 'default').
* Added jinja2 and MarkupSafe to vendored packages.
* Spec.concretize() sets mutual spec-package references
The correct place to set the mutual references between spec and package
objects at the end of concretization. After a call to concretize we
should now be ensured that spec is the same object as spec.package.spec.
Code in `build_environment.py` that was performing the same operation
has been turned into an assertion to be defensive on the new behavior.
* Improved code and data layout for modules and related tests.
Common fixtures related to module file generation have been extracted
in `conftest.py`. All the mock configurations for module files have been
extracted from python code and have been put into their own yaml file.
Added a `context_property` decorator for the template engine, to make
it easy to define dictionaries out of properties.
The default for `verbose` in `modules.yaml` is now False instead of True.
* Extendable module file contexts + short description from docstring
The contexts that are used in conjunction with `jinja2` templates to
generate module files can now be extended from package.py and
modules.yaml.
Module files generators now infer the short description from package.py
docstring (and as you may expect it's the first paragraph)
* 'module refresh' regenerates all modules by default
`module refresh` without `--module-type` specified tries to
regenerate all known module types. The same holds true for `module rm`
Configure options used at build time are extracted and written into the
module files where possible.
* Fixed python3 compatibility, tests for Lmod and Tcl.
Added test for exceptional paths of execution when generating Lmod
module files.
Fixed a few compatibility issues with python3.
Fixed a bug in Tcl with naming_scheme and autoload + unit tests
* Updated module file tutorial docs. Fixed a few typos in docstrings.
The reference section for module files has been reorganized. The idea is
to have only three topics at the highest level:
- shell support + spack load/unload use/unuse
- module file generation (a.k.a. APIs + modules.yaml)
- module file maintenance (spack module refresh/rm)
Module file generation will cover the entries in modules.yaml
Also:
- Licenses have been updated to include NOTICE and extended to 2017
- docstrings have been reformatted according to Google style
* Removed redundant arguments to RPackage and WafPackage.
All the callbacks in `RPackage` and `WafPackage` that are not build
phases have been modified not to accept a `spec` and a `prefix`
argument. This permits to leverage the common `configure_args` signature
to insert by default the configuration arguments into the generated
module files. I think it's preferable to handling those packages
differently than `AutotoolsPackage`. Besides only one package seems
to override one of these methods.
* Fixed broken indentation + improved resiliency of refresh
Fixed broken indentation in `spack module refresh` (probably a rebase
gone silently wrong?). Filter the writers for blacklisted specs before
searching for name clashes. An error with a single writer will not
stop regeneration, but instead will print a warning and continue
the command.
- '\b' in regular expression needs to be in a raw string (r'\b')
- Regression test that would've caught this was unintentionally disabled
- This fixes the string and the test
Fixes#4112
This commit extends the support of the AutotoolsPackage methods
`with_or_without` and `enable_or_disable` to bool-valued variants. It
also defines for those functions a convenience short-cut if the
activation parameter is the prefix of a spec (like in
`--with-{pkg}={prefix}`).
This commit also includes:
* Updates to viennarna and adios accordingly: they have been modified to
use `enable_or_disable` and `with_or_without`
* Improved docstrings in `autotools.py`. Raise `KeyError` if name is
not a variant.
* Added support to query packages by tags.
- The querying commands `spack list`, `spack find` and `spack info` have
been modified to support querying by tags. Tests have been added to
check that the feature is working correctly under what should be the
most frequent use cases.
* Refactored Repo class to make insertion of new file caches easier.
- Added the class FastPackageChecker. This class is a Mapping from
package names to stat info, that gets memoized for faster access.
- Extracted the creation of a ProviderIndex to its own factory function.
* Added a cache file for tags.
- Following what was done for providers, a TagIndex class has been added.
This class can serialize and deserialize objects from json. Repo and
RepoPath have a new method 'packages_with_tags', that uses the TagIndex
to compute a list of package names that have all the tags passed as
arguments.
On Ubuntu 14.04 the effect if the cache reduces the time for spack list
from ~3sec. to ~0.3sec. after the cache has been built.
* Fixed colorization of `spack info`
- Python I/O would not properly interleave (or appear) with output from
subcommands.
- Add a flusing wrapper around sys.stdout and sys.stderr when
redirecting, so that Python output is synchronous with that of
subcommands.
Adds the "buildcache" command to spack. The buildcache command is
used to create gpg signatures for archives of installed spack
packages; the signatures and archives are placed together in a
directory that can be added to a spack mirror. A user can retrieve
the archives from a mirror and verify their integrity using the
buildcache command. It is often the case that the user's Spack
instance is located in a different path compared to the Spack
instance used to generate the package archive and signature, so
this includes logic to relocate the RPATHs generated by Spack.
Fixes#4898
Constraints that were supposed to be conditionally activated for
specified values of a single-valued variant were being activated
unconditionally in the case that the variant was associated with
an implicit dependency. For example if X->Y->Z and Y places a
conditional constraint on Z for a given single-valued variant on
Y, then it would have been applied unconditionally when
concretizing X.
For packages which contain a mix of versions with formats X.Y and
X.Y.Z, if the user entered an X.Y version as a preference in
packages.yaml, Spack would get confused and favor any version A.B.Z
where X=A and Y=B. In the case where there is a mix of these version
types, this commit updates preferences so Spack will favor an exact
match.
Adds SpackCommand class allowing Spack commands to be easily in Python
Example usage:
from spack.main import SpackCommand
info = SpackCommand('info')
out, err = info('mpich')
print(info.returncode)
This allows easier testing of Spack commands.
Also:
* Simplify command tests
* Simplify mocking in command tests.
* Simplify module command test
* Simplify python command test
* Simplify uninstall command test
* Simplify url command test
* SpackCommand uses more compatible output redirection
* During install, remove prior unfinished installs
If a user performs an installation which fails, in some cases the
install prefix is still present, and the stage path may also be
present. With this commit, unless the user specifies
'--keep-prefix', installs are guaranteed to begin with a clean
slate. The database is used to decide whether an install finished,
since a database record is not added until the end of the install
process.
* test updates
* repair_partial uses keep_prefix and keep_stage
* use of mock stage object to ensure that stage is destroyed when it should be destroyed (and otherwise not)
* add --restage option to 'install' command; when this option is not set, the default is to reuse a stage if it is found.
