- `stage.source_path` was previously overloaded; it returned `None` if it
didn't exist and this was used by client code
- we want to be able to know the `source_path` before it's created
- make stage.source_path available before it exists.
- use a well-known stage source path name, `$stage_path/src` that is
available when `Stage` is instantiated but does not exist until it's
"expanded"
- client code can now use the variable before the stage is created.
- client code can test whether the tarball is expanded by using the new
`stage.expanded` property instead of testing whether `source_path` is
`None`
- add tests for the new source_path semantics
- make tty.msg, tty.info, etc. print the exception type and stringified
message if the message argument is an exception.
- simplify parts of the code that call tty.debug(str(e))
- add extra tty.debug statements in places where exceptions were
previously ignored
- `spack graph --static` (and `spack.graph.dot_graph`) now do the "right
thing" and print the possible dependency graph of provided packages.
- `spack graph --static` no longer concretizes specs, as it only relies
on class level metadata
- Previously the behavior was not consistent -- `spack graph --static`
would graph possible dependencies of concrete specs, but would only
include some of them. The new code properly pursues all possible
dependencies, and allows traversing by different dependency types.
- `spack dependencies` can now take a --deptype argument to only traverse
particular deptypes
- add a new "common" argument for deptype in spack.cmd.common.arguments
- Database.installed_relatives() can now also take a deptype argument
- this is used by `spack dependencies --installed`
- `PackageBase.possible_dependencies` now:
- accepts a deptype param that controls dependency types traversed
- returns a dict mapping possible depnames to their immediate possible
dependencies (this lets you build a graph easily)
- Add tests for PackageBaes
- The 'name' attribute for packages was being set in DirectiveMeta, which
wasn't consistent with other class properties (like fullname, etc.)
- Move it to be a class property of `PackageMeta`, and add the
corresponding property method wrapper on `PackageBase`
* add c99_flag, c11_flag to compiler class

Previously, module files were not set with the same permissions as the package installation. For world-readable packages, this would not cause a problem. For group readable packages, it does:
```
packages:
mypackage:
permissions:
group: mygroup
read: group
write: group
```
In this case, the modulefile is unreadable by members of the group other than the one who installed it. Add logic to the modulefile writers to set the permissions based on the configuration in `packages.yaml`
* Build cache: relocate path to spack/bin/sbang in text files.
* Found in testing.
* update packaging test
* Make sbang replacement including #!/bin/bash. Add an additional spack prefix replacement to fix stage directory references.
* flake8
* Use buildinfo.get() so old buildcaches without buildinfo['spackprefix'] can be read.
* config:build_jobs now controls the number of parallel jobs to spawn during
builds, but cannot ever exceed the number of cores on the machine.
* The default is set to 16 or the number of available cores, whatever
is lowest.
* Updated docs to reflect the changes done to limit parallel builds
- `gettext_uuid=True` makes every commit update every .pot file in spack/localized-docs,
and speeds up the internationalized doc build slightly.
- Optimize for less repository churn, and use `python-levenshtein` to accelerate
the build instead.
- make all Spack paths relative to a `_spack_root` symlink, so that we
can easily relocate the docs build *outside* lib/spack/docs
- set some useful defaults for gettext translation variables in conf.py
- update `relativeinclude` and other references to the spack root in the
RST files to use _spack_root
- Add a `--update FILE` option to `spack list`
- Output is written to the file only if any package is newer than the file
- Simplify the code in docs/conf.py using this new option
The Spack documentation currently hard-codes some functionality in
`conf.py`, which makes the doc build less "pluggable" for things like
localized doc builds.
In particular, we unconditionally generate an index of commands and a
package list as part of the docs, but those should really only be done if
things are not up to date.
This commit does the following:
- Add `--header` option to `spack commands` so that it can do the work of
prepending text to its output.
- Add `--update FILE` option to `spack commands` that makes it generate a
new command index *only* if FILE is out of date w.r.t. commands in the
Spack source.
- Simplify code in `conf.py` to use these options and only update the
command index when needed.
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`)
* Add Fujitsu compiler to Spack.
* Fixes for flake8
* Chenges location of FCC to subdirectory called case-insensitive
* Add compiler tests for Fujitsu compiler
* Modify the logic of taking compiler version for new version of Fujitsu compiler
The regex used for finding the Cray OS version from the PrgEnv-cray
module was not exact and was at times pulling the version from other
PrgEnv modules. This updates the regular expression to be more exact.
Adds executable=/bin/bash into Popen. We discovered this bug while
working in a csh/tsch environment. By executing with /bin/bash we ensure
that the module command works.
#8612 added command extensions to Spack: a command implemented in a
separate directory. This improves the implementation by allowing
the command to import additional utility code stored within the
established directory structure for commands.
This also:
* Adds tests for command extensions
* Documents command extensions (including the expected directory
layout)
- `svn info` prints different results depending on the system locale
- in particular, Japanese output doesn't contain "Revision:"
- Change Spack code to use XML output instead of using the human output
Add fixes to support multiple installs and dependents using a subset
of IntelPackage functionality.
* Update IntelPackage to only return scalapack libraries if the root
spec depends on MPI: scalapack requires MPI to be mentioned as a
dependency in the DAG. Package builds using intel-mkl for its
blas/lapack implementations but not for scalapack were failing to
build.
Ideally it would be possible to ask if any of the packages in the
DAG are actually requesting the scalapack functionality provided by
the IntelPackage and only return scalapack libs in that case, but
that is not easily done at this time.
Fixes#11314Fixes#11289
* set HOME when the intel silent installer is run. This prevents the
installer from using the ~/intel directory (which can cause
conflicts for multiple installs of the same IntelPackage)
Fixes#9713
Use new `module` function instead of `get_module_cmd`
Previously, Spack relied on either examining the bash `module()` function or using the `which` command to find the underlying executable for modules. More complicated module systems do not allow for the sort of simple analysis we were doing (see #6451).
Spack now uses the `module` function directly and copies environment changes from the resulting subprocess back into Spack. This should provide a future-proof implementation for changes to the logic underlying the module system on various HPC systems.
Add two functions to the EnvironmentModifications object to help
users sanitize environment variables in their package definitions:
* deprioritize_system_paths: this keeps system paths in the
environment variable but moves them to the end.
* prune_duplicate_paths: remove any duplicate paths from the
variable
This includes testing for the new functions as well as for
(previously-untested) old convenience functions for environment
variable manipulation.
This also adds special handling for bash functions so they
will be defined when the exported environment file is sourced.
Fixes#11335
Update the Spack compiler wrappers to add the headerpad_max_install_names
linker flag on MacOS. This allows the install_name_tool to rewrite
the RPATH entry of the binary to be longer if needed. This is
primarily useful for creating and distributing binary caches of
packages (i.e. using the "spack buildcache" command); binary caches
created on MacOS before this commit may not successfully relocate
(if the target root path is larger).
* Added a function that concretizes specs together
* Specs concretized together are copied instead of being referenced
This makes the specs different objects and removes any reference to the
fake root package that is needed currently for concretization.
* Factored creating a repository for concretization into its own function
* Added a test on overlapping dependencies
* 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
- `spack edit` previously used `spack.util.executable` `Executable` objects,
and didn't `exec` the editor like you'd expect it to
- This meant that Spack was still running while your editor was, and
stdout/stdin were being set up in weird ways
- e.g. on macOS, if you call `spack edit` with `EDITOR` set to the
builtin `emacs` command, then type `Ctrl-g`, the whole thing dies with
a `==> Error: Keyboard interrupt`
- Fix all this by changing spack.util.editor to use `os.execv` instead of
Spack's `Executable` object
Also add constructor to NoLibrariesError which can either take an
error message (like other SpackErrors) or a name and prefix (in
which case the error message is constructed).
PR #10758 made a slight change to find_versions_of_archive() which included
archive_url in the search process. While this fixed `spack create` and
`spack checksum` missing command-line arguments, it caused `spack
install` to prefer those URLs over those it found in the scrape process.
As a result, the package url was treated as a list_url causing all R
packages to stop fetching once the package was updated on CRAN.
This patch is more selective about including the archive_url in the
remote versions, explicitly overriding it with matching versions found
by the scraper.
f242f5f8 changed the format strings but maintained backwards
compatibility in all cases except one: The list of valid tokens for
the module naming schemes was not updated properly to contain both
the new and old styles for compilers and package names.
This PR re-adds the old tokens into the list of valid tokens.
#11152 added documentation for #8772 but some details were based on
an earlier implementation that had changed by the time #8772 was
merged. In particular, #11152 mentioned that upstream Spack instances
were configured in config.yaml, when in fact they should be placed in
a separate upstreams.yaml config file; this PR updates the
documentation accordingly.
fixes#11159
The 'namespace' argument to both Repo and RepoPath were used to set the
"super namespace". Currently it seems to be vestigial as the only
"super namespace" allowed for packages is 'spack.pkg' since 39c9bbf
* Make a separate CDash report for each package installed
Previously, we generated a single CDash report ("build") for the complete results
of running a `spack install` command. Now we create a separate CDash build for
each package that was installed.
This commit also changes some of the tests related to CDash reporting.
Now only one of the tests exercises the code path of uploading to a
(nonexistent) CDash server. The rest of the related tests write their reports
to disk without trying to upload them.
* Don't report errors to CDash for successful packages
Convert errors detected by our log scraper into warnings when the package
being installed reports that it was successful.
* Report a maximum of 50 errors/warnings to CDash
This is in line with what CTest does. The idea is that if you have more than
50 errors/warnings you probably aren't going to read through them all anyway.
This change reduces the amount of data that we need to transfer and store.
* Update spec format to simpler syntax, maintain backwards compatibility
* Switch to new spec.format method throughout internals
* update package files for new format strings
* documentation and minor code cleanup. removed nonsensical variant sigils
Fixes#11070#11010
Spack attempts to intercede on behalf of all compiler invocations for
a build. This involves adding its wrappers to PATH. Cray systems
include a "ftn" executable and Spack was only redirecting this call
when the Spec was built with cce. This updates the compiler wrappers
to add "ftn" in all cases.
The default (implied) behavior for all environments, as of ea1de6b,
is that an environment will maintain a view in a location of its
choosing. ea1de6b explicitly recorded all three possible states of
maintaining a view:
1. Maintain a view, and let the environment decide where to put it
(default)
2. Maintain a view, and let the user decide
3. Don't maintain a view
This commit updates the config writer so that for case [1], nothing
will be written to the config.yaml. This will not change any existing
behavior, it just serves to keep the config more compact.
Compilers are treated separately from other dependencies in Spack.
#10761 added the option to automatically install compilers when a
package specifies using a compiler that is not available in Spack.
However, this did not work correctly for dependency packages (it
would only build a compiler for the root of an install DAG). This
commit enables the building of compilers for dependency packages.
Environments are nowm by default, created with views. When activated, if an environment includes a view, this view will be added to `PATH`, `CPATH`, and other shell variables to expose the Spack environment in the user's shell.
Example:
```
spack env create e1 #by default this will maintain a view in the directory Spack maintains for the env
spack env create e1 --with-view=/abs/path/to/anywhere
spack env create e1 --without-view
```
The `spack.yaml` manifest file now looks like this:
```
spack:
specs:
- python
view: true #or false, or a string
```
These commands can be used to control the view configuration for the active environment, without hand-editing the `spack.yaml` file:
```
spack env view enable
spack env view envable /abs/path/to/anywhere
spack env view disable
```
Views are automatically updated when specs are installed to an environment. A view only maintains one copy of any package. An environment may refer to a package multiple times, in particular if it appears as a dependency. This PR establishes a prioritization for which environment specs are added to views: a spec has higher priority if it was concretized first. This does not necessarily exactly match the order in which specs were added, for example, given `X->Z` and `Y->Z'`:
```
spack env activate e1
spack add X
spack install Y # immediately concretizes and installs Y and Z'
spack install # concretizes X and Z
```
In this case `Z'` will be favored over `Z`.
Specs in the environment must be concrete and installed to be added to the view, so there is another minor ordering effect: by default the view maintained for the environment ignores file conflicts between packages. If packages are not installed in order, and there are file conflicts, then the version chosen depends on the order.
Both ordering issues are avoided if `spack install`/`spack add` and `spack install <spec>` are not mixed.
When providing a track, the cdash reporter will format the stamp
itself, as it has always done, and register the build during the
package installation process. When providing a stamp, it should
first be formatted as cdash expects, and then cdash will be sure
to report results to same build id which was registered manually
elsewhere.
* Update Spec.prefix to have special case for 'None' in database path; regression test
* Update in database reader rather than spec
* Change assertion to conditional + raise
* Added test for concrete check in Spec.prefix
The module_parsing test checks whether the module function is available
by looking for the string 'not found'. If the user has set a different
locale, the test can assume that the module function is available when
it actually is not.
* Split get_compiler_version into two functions:
get_compiler_version_output runs the compiler with the relevant
option to print the version; extract_version_from_output determines
the version by examining this output. This makes it easier to test
the customized version detection for each compiler. Users can
customize this by overriding the following:
* version_argument: this is the argument that tells the compiler to
print its version. It assumes that the compiler will report its
version if invoked with a single option (like "--version")
* version_regex: the regular expression used to extract the version
from the compiler argument. This assumes that a regular
expression is sufficient to extract the version, and that the
version can be extracted from a single capture group (Spack uses
the first capture group)
* default_version: allows you to completely override all version
detection logic
* get_compiler_version_output: if getting the compiler to report
its version is more complex than invoking it with a single arg
* extract_version_from_output: if it is difficult to define a regex
that can be used to extract the version from the output
* Added tests for version detection of most compilers
* Removed redundant code from xl_r compiler class (by inheriting
from xl compiler definition)
Replace the original implementation of the "memoized" decorator with
an implementation that exposes the docstring and arguments of the
wrapped function. This is achieved using functools.wraps.
This provides a mechanism to implement a new Spack command in a
separate directory, and with a small configuration change point Spack
to the new command.
To register the command, the directory must be added to the
"extensions" section of config.yaml. The command directory name must
have the prefix "spack-", and have the following layout:
spack-X/
pytest.ini #optional, for testing
X/
cmd/
name-of-command1.py
name-of-command2.py
...
tests/ #optional
conftest.py
test_name-of-command1.py
templates/ #optional jinja templates, if needed
And in config.yaml:
config:
extensions:
- /path/to/spack-X
If the extension includes tests, you can run them via spack by adding
the --extension option, like "spack test --extension=X"
* 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)
Change the location of the CMake build area from the staged source
directory to the stage base directory.
This change allows CMake packages to refer to the build directory in
setup_environment (e.g. if tests need to have a directory in PATH):
Staging happens after the call to setup_environment(), and if the
stage area does not exist, then spec.stage.source_path returns None.
To accommodate this change, archived files (like config.log for
Autotools packages) are archived relative to the stage base directory
rather than the expanded source directory.
Other packages (those not using CMake) will still use the staged
source directory as the default working directory for builds (and
will still be unable to reference this directory in
setup_environment())
When multiple instances of environment-modules were installed with
different architectures, Spack was not retrieving the installation
appropriate for the current architecture when finding the module
prefix.
* Fixed some issues with CUDA-Intel compiler conflicts.
* Comment about expressing CUDA-compiler conflicts.
* More precise conflicts and also add support for Intel 19.0
If the user has set the environment variable VISUAL, it will be used
in preference to EDITOR for all Spack editing activities. If VISUAL
is not set or fails (perhaps due to a lack of graphical editing
capabilities),EDITOR will be used instead. We fall back to one of
several common editors if neither bears fruit.
This feature has been tailored to:
* Provide identical behavior to the previous implementation in the
case that VISUAL is not set.
* Not require any change to code utilizing the editor feature.
* Follow usual UNIX behavior concerning VISUAL and EDITOR.
* Fix clearing EnvironmentModifications with python2
* Add EnvironmentModifications::clear unit test
Use re-assignment rather than del to clear array
* Fix flake issues
Fixes#10191
* Add more regular expressions to detect clang versions that were
not being picked up
* Add a test for parsing versions from the output of Clang (this
does not run Clang, but rather uses example outputs from Clang)
* Separate Clang version parsing into its own method (to make it
easier to test)
Currently, only C headers are considered, causing build failures for
packages depending on, e.g., netcdf-fortran and xerces-c. Additionally,
the regex used to look for the include path component did not consider
word boundaries, causing false matches.
* Create option to build missing compilers and add them to config before installing packages that use them
* Clean up kwarg passing for do_install, put compiler bootstrapping in separate method
* Rework of buildcache creation and install prefix checking using the functions introduced in
https://github.com/spack/spack/pull/9199
Instead of replacing rpaths with placeholder and then checking strings, make use of the functions
relocate.is_recocatable and relocate.is_file_relocatable to decide if a package needs the allow-root option.
This fixes a problem where the placeholder path was not in the first rpath entry. This was seen in c++ libraries and binaries because the compiler was outside the spack install base path and always appears first in the rpath.
Instead of checking the first rpath entry, all rpaths have the placeholder path and the old install path (if it exists) replaced with the new install path.
* flake8
* Added the `spack buildcache preview` sub-command
This is similar to `spack spec -I` but highlights which nodes in a DAG
are relocatable and which are not.
spec.tree has been generalized a little to accept a status function,
instead of always showing the install status
The current implementation works only for ELF, and needs to be
generalized to other platforms.
* Added a test to check if an executable is relocatable or not
This test requires a few commands to be present in the environment.
Currently it will run only under python 3.7 (which uses Xenial instead
of Trusty).
* Added tests for the 'buildcache preview' command.
* Fixed codebase after rebase
* Fixed the list of apt addons for Python 3.7 in travis.yaml
* Only check ELF executables and shared libraries. Skip checking virtual or external packages. (#229)
* Fixed flake8 issues
* Add handling for macOS mach binaries (#231)
The environment modules package has been updated to include
versions up to 4.0.0. The url of the package and the homepage
have been updated accordingly.
The `spack bootstrap` command now builds version 3.2.10 of
the environment-modules package, and will do until #10708
is fixed.
This restores the use of Package.headers when computing -I options
for building a package that was added in #8136 and reverted in
#10604. #8136 used utility logic that located all header files in
an installation prefix, and calculated the -I options as the
immediate roots containing those header files.
In some cases, for a package containing a directory structure like
prefix/
include/
ex1.h
subdir/
ex2.h
dependents may expect to include ex2.h relative to 'include', and
adding 'prefix/include/subdir' as a -I was causing errors,
in particular if ex2.h has the same name as a system header.
This updates header utility logic to by default return the base
"include" directory when it exists, rather than subdirectories.
It also makes it possible for package implementers to override
Package.headers to return the subdirectory when it is required
(for example with libxml2).
Spack warns users when a dependency package updates CPATH. This
warning message is generating bug reports and alarm in cases where
there is no problem. For now this downgrades the warning message to
the debug level, so it only shows up if something goes wrong for the
user and they ask for more information from Spack.
This spack command adds a new schema for a file which describes the
builder containers available, along with the compilers availabe on
each builder. The release-jobs command then generates the .gitlab-ci.yml
file by first expanding the release spec set, concretizing each spec
(in an appropriate docker container if --this-machine-only argument is
not provided on command line), and then combining and staging all the
concrete specs as jobs to be run by gitlab.
Adds four new sub-commands to the buildcache command:
1. save-yaml: Takes a root spec and a list of dependent spec names,
along with a directory in which to save yaml files, and writes out
the full spec.yaml for each of the dependent specs. This only needs
to concretize the root spec once, then indexes it with the names of
the dependent specs.
2. check: Checks a spec (via either an abstract spec or via a full
spec.yaml) against remote mirror to see if it needs to be rebuilt.
Comparies full_hash stored on remote mirror with full_hash computed
locally to determine whether spec needs to be rebuilt. Can also
generate list of specs to check against remote mirror by expanding
the set of release specs expressed in etc/spack/defaults/release.yaml.
3. get-buildcache-name: Makes it possible to attempt to read directly
the spec.yaml file on a remote or local mirror by providing the path
where the file should live based on concretizing the spec.
4. download: Downloads all buildcache files associated with a spec
on a remote mirror, including any .spack, .spec, and .cdashid files
that might exist. Puts the files into the local path provided on
the command line, and organizes them in the same hierarchy found on
the remote mirror
This commit also refactors lib/spack/spack/util/web.py to expose
functionality allowing other modules to read data from a url.
- add CombinatorialSpecSet in spack.util.spec_set module.
- class is iterable and encaspulated YAML parsing and validation.
- Adjust YAML format to be more generic
- YAML spec-set format now has a `matrix` section, which can contain
multiple lists of specs, generated different ways. Including:
- specs: a raw list of specs.
- packages: a list of package names and versions
- compilers: a list of compiler names and versions
- All of the elements of `matrix` are dimensions for the build matrix;
we take the cartesian product of these lists of specs to generate a
build matrix. This means we can add things like [^mpich, ^openmpi]
to get builds with different MPI versions. It also means we can
multiply the build matrix out with lots of different parameters.
- Add a schema format for spec-sets
Fixes#10617Fixes#10624Closes: #10619#8136 dependended entirely on spec.libs to retrieve library directories
from dependencies. By default this function only retrieves libraries if
their name is something like lib<package> (e.g. "libfoo.so" for a
package called "Foo"). This unconditionally adds lib/lib64 directories
for each dependency as link/rpath directories.
This also filters system paths from link/rpaths/include directories and
removes duplicated paths that #8136 could add.
If the -f <specyamlfile> argument to install is used (rather than
providing package specs on the command line), CDash throws an exception
due to missing the installation command (the packages targeted for
install). This fixes that behavior so CDash reporting succeeds in
either case.
fixes#10601
Due to a bug this attribute is wrong for packages that use directories
as namespaces. For instance it will add "<boost-prefix>/include/boost"
instead of "<boost-prefix>/include" to the include path.
As a minor addition a few loops in the compiler wrappers have been
simplified.
Fixes#7855Closes#8070Closes#2645
When searching for library directories (e.g. to add "-L" arguments to
the compiler wrapper) Spack was only trying the "lib/" and "lib64/"
directories for each dependency install prefix; this missed cases
where packages would install libraries to subdirectories and also was
not customizable. This PR makes use of the ".headers" and ".libs"
properties for more-advanced location of header/library directories.
Since packages can override the default behavior of ".headers" and
".libs", it also allows package writers to customize.
The following environment variables which used to be set by Spack
for a package build have been removed:
* Remove SPACK_PREFIX and SPACK_DEPENDENCIES environment variables as
they are no-longer used
* Remove SPACK_INSTALL environment variable: it was not used before
this PR
* fix permission setter
Fix a typo in islink test when applied to files.
* os.walk explicitly set not to follow links
The algorithm strongly rely on not following links.
* Note that `none` is the default for lmod autoload
Save a bit of confusion by *explicitly* pointing out that `none` is
the default value for autoload in the lmod module file generator.
* Add a tip re building software externally
Add a tip about using `autoload: all` when building packages outside
of the tree that use artifacts (e.g. libraries, includes) within the
tree.
CMake supports the notion of secondary generators which provide extra
information to (e.g.) IDEs over and above that normally provided by
the primary generator. Spack only supports the 'Unix Makefiles' and
'Ninja' primary generators but was not parsing out the primary
generator when a secondary generator was also included (e.g. for
a generator attribute like 'Codeblocks - Ninja'). This adds a regex
for extracting the primary generator for validation.
Since the secondary generator is irrelevant to a Spack build, it is
passed on to CMake without further validation.

Debug output now includes the output of modulecmd executions. Only
output module content when a failure occurs; always report when a
module is loaded/unloaded.
"spack install" will install all packages added to the current
environment. When this included external packages, the environment
update would fail because it would attempt to copy log files that
were only generated if Spack handled the install itself. This skips
that step for external packages.

Binary caches of packages with absolute symlinks had broken symlinks.
As a stopgap measure, #9747 addressed this by replacing symlinks with
copies of files when creating binary cached packages.
This reverts #9747 and instead, either relative-izes the symlink or
rewrites the target. If the binary cache is created using '--rel' (as
in "spack buildcache create --rel...") then absolute symlinks will be
replaced with relative symlinks (in addition to making RPATHs relative
as before); otherwise they are rewritten (when the binary cache is
unpacked and installed).
The current output of buildcache list is very verbose and I feel like
some details are getting lost. By making the output similar to find, I
think users will be able to get a better overview of what is stored in
the cache.

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.
Fixes#10284#10152 replaced shutil.move with llnl's copy and copy_tree for
resources. This did not copy permissions so led to later failures
if an executable was copied (e.g. a configure script). This uses
install/install_tree instead, which preserve permissions.

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
Non-expanded resources were being deleted from the cache on account
of two behaviors:
* ResourceStage was moving files rather than copying them, and uses
"os.path.realpath" to resolve symlinks
* CacheFetchStrategy creates a symlink to a cached resource rather
than copying it
This alters the first behavior: ResourceStage now copies the file
rather than moving it.
"mirror create" was invoking a package's do_patch method in order to
retrieve and archive URL patches. If a package implements a "patch"
method, this is also called as part of do_patch; this failed when the
package-specific implementation referred to environment variables
that are only available at the time the package is built
(e.g. "spack_cc").
This change introduces fetch and clean methods for patches. They are
no-ops for FilePatch but perform the appropriate actions for
UrlPatch. This allows "mirror create" to invoke do_fetch, which does
not call the package's patch method.
- in many files, regular strings were used in places where raw strings
should've been used.
- convert these to raw strings and get rid of new flake8 errors
This PR improves the validation of `modules.yaml` by introducing a custom validator that checks if an attribute listed in `properties` or `patternProperties` is a valid spec. This new check applied to the test case in #9857 gives:
```console
$ spack install szip
==> Error: /home/mculpo/.spack/linux/modules.yaml:5: "^python@2.7@" is an invalid spec [Invalid version specifier]
```
Details:
* Moved the set-up of a custom validator class to spack.schema
* In Spack we use `jsonschema` to validate configuration files
against a schema. We also need custom validators to enforce
writing default values within "properties" or "patternProperties"
attributes.
* Currently, validators were customized at the place of use and with the
recent introduction of environments that meant we were setting-up and
using 2 different validator classes in two different modules.
* This commit moves the set-up of a custom validator class in the
`spack.schema` module and refactors the code in `spack.config` and
`spack.environments` to use it.
* Added a custom validator to check if an attribute is a valid spec
* Added a custom validator that can be used on objects, which yields an
error if the attribute is not a valid spec.
* Updated the schema for modules.yaml
* Updated modules.yaml to fix a few inconsistencies:
- a few attributes were not tested properly using 'anyOf'
- suffixes has been updated to also check that the attribute is a spec
- hierarchical_scheme has been updated to hierarchy
* Removed $ref from every schema
* $ref is not composable or particularly legible
* Use python dicts and regular old variables instead.
- The nested directive implementation was broken for python 3
- directive results were not properly removed from the directive list
when it was processed in the DirectiveMeta metaclass.
- the issue was that remove_directives only descended into a list or
tuple, but in Python3, the initial value passed to the function is a
view of dictionary values.
- make it a list to fix things, and add a regression test.
- currently just looks at patches
- allows you to find out which package applied a patch to a spec
- intended to work with tarballs and resources in the future.
- add tab completion for `spack resource` and subcommands
- previously, if a concrete sub-DAG with patched specs was written out
and read back in, its patches would not be found because the dependent
that patched it was no longer in the DAG.
- Add a test to ensure that the PatchCache handles this case.
- Also add tests to ensure that patch objects are properly created from
Specs -- previously we only checked that the patches were on the Spec.
- this fixes a bug where if we save a concretized sug-DAG where a package
had been patched by a dependent, and the dependent was not in the DAG,
we would not read in all patches correctly.
- Rather than looking up patches in the DAG, we look them up globally
from an index created from the entire repository.
- The patch cache is a bit tricky for several reasons:
- we have to cache information from packages, specifically, the patch
level and working directory.
- FilePatches need to know which package owns them, so that they can
figure out where the patch lives. The repo can change locations from
run to run, so we have to store relative paths and restore them when
the cache is reloaded.
- Patch files can change underneath the cache, because repo indexes
only update on package changes. We currently punt on this -- there
are stub methods for needs_update() that will need to check patch
files when packages are loaded. There isn't an easy way to do this
at global indexing time without making the FastPackageChecker a lot
slower. This is TBD for a future commit.
- Currently, the same patch can only be used one way in a package. That
is, if it appears twice with different level/working_dir settings,
bad things will happen. There's no package that current uses the
same patch two different ways, so we've punted on this as well, but
we may need to fix this in the future by moving a lot of the metdata
(level, working dir) to the spec, and *only* caching sha256sums in
the PatchCache. That would require some much more complicated tweaks
to the Spec, so we're holding off on that til later.
- This required patches to be refactored somewhat -- the difference
between a UrlPatch and a FilePatch is still not particularly clean.
- indexes should use json, not YAML, to optimize for speed
- only use YAML in human-editable files
- this makes ProviderIndex consistent with other indexes
- virtual provider cache and tags were previously generated by nearly
identical but separate methods.
- factor out an Indexer interface for updating repository caches, and
provide implementations for each type of index (TagIndex,
ProviderIndex) so that more can be added if needed.
- Among other things, this allows all indexes to be updated at once.
This is an advantage because loading package files is the real
overhead, and building the indexes once the packages are loaded is
trivial. We avoid extra bulk read-ins by generating all package indexes
at once.
- This can be extended for dependents (reverse dependencies) and patches
later.
- cleanup patch.py:
- make patch.py constructors more understandable
- loosen coupling of patch.py with package
- in Package: make package_dir, module, and namespace class properties
- These were previously instance properties and couldn't be called from
directives, e.g. in patch.create()
- make them class properties so that they can be used in class definition
- also add some instance properties to delegate to class properties so
that prior usage on Package objects still works
- When returning string output, use text_type and decode utf-8 in Python
2 instead of using `str`
- This properly handles unicode, whereas before we would pass bad strings
to colify in `spack blame` when reading git output
- add a test that round-trips some unicode through an Executable object
* Remove /nfs/tmp2 from default configuration
* /nfs/tmp2 is going away from LC... and doesn’t exist for the rest of the world.
* update documentation to remove /nfs/tmp2 as well
* Record build output as an array of lines rather than concatenating to a
single large string.
* Use string.find to avoid running re.search on every line of output.
- some commands were missed in the rollout of spack environments
- this makes all commands that need to disambiguate specs restrict the
disambiguation to installed packages in the active environment, as
users would expect
* This fixes a number of bugs:
* Patches were not properly downloaded and added to mirrors.
* Mirror create didn't respect `list_url` in packages
* Update the `spack mirror` command to add all packages in the
concretized DAG (where originally it only added the package specified
by the user). This is required in order to collect patches that are specified
by dependents. Example:
* if X->Y and X requires a patch on Y called Pxy, then Pxy will only
be discovered if you create a mirror with X.
* replace confusing --one-version-per-spec option for `spack mirror create`
with --versions-per-spec; support retrieving multiple versions for
concrete specs
* Implementation details:
* `spack mirror create` now uses regular staging logic to download files
into a mirror, instead of reimplementing it in `add_single_spec`.
* use a separate resource caching object to keep track of new
resources and already-existing resources; also accepts storing
resources retrieved from a cache (unlike the local cache)
* mirror cache object now stores resources that are considered
non-cachable, like (e.g. the tip of a branch);
* the 'create' function of the mirror module no longer traverses
dependencies since this was already handled by the 'mirror' command;
* Change handling of `--no-checksum`:
* now that 'mirror create' uses stages, the mirror tests disable
checksums when creating the mirror
* remove `no_checksum` argument from library functions - this is now
handled at the Spack-command-level (like for 'spack install')
- all multimethod tests are now run for both `multimethod` and
`multimethod-inheritor`
- do this with a parameterized fixture (pkg_name) that runs the same
tests on both
- Since early Spack versions, the SpecParser has (weirdly) been
responsible for initializing Spec fields.
- This refactors initialization to take place in Spec.__init__, as it
probably should have originally.
- This makes the code easier to read, the parser easier to understand,
and removes the use of __new__ in the parser to initialize the Spec.
- This also makes it possible to make a completely empty Spec with
`Spec()` -- this is an abstract Spec that will match anything.
* "spack install" now uses cache by default, update examples accordingly
* Replace some example packages with others
* Packing tutorial reference to "spack env" replaced with "spack build-env"
* Command line prompts in examples are shortened
* Example output (including paths) are updated to be more relevant to training environment
Update all examples that need an MPI provider to build with MPICH; reorganize so that fixing MPICH (as part of environment section) comes first in the tutorial (most examples in the tutorial use an MPI provider).
- previously, uninstall would complain if a spec was needed by an
environment.
- Now, we analyze dependents and dependent environments and simply remove
(not uninstall) specs that are needed by environments
- with no arguments, these commands will now edit or dump the
environment's `spack.yaml` file.
- users may not know where named environments live
- this makes it convenient for users to get to the spack.yaml
configuration file for their named environment.
* Update Makefile to use property methods ("build_targets"/"install_targets")
to demonstrate their usage
* Fix highlighting
* Change cbench example to ESMF:
CBench package file was changed and no longer uses the example shown in
the old docs
Scopes added with -C are now referred to as "custom scopes"
rather than "command line scopes". "command line scope" now refers
to specific config options that are set on the command line (like
"--insecure")
- default is still to use the cache, but we've added back the
`--use-cache` argument so that scripts that used it are still correct.
- `--no-cache` is stil present and is mutually exclusive with `--use-cache`
* Introduce FFTW2 and FFT3 providers for Intel-MKL and FFTW Spack packages.
* make fftw default package for fftw-api virtual package
* virtual package test assertion now provides location of default virtual packages.
* Change name of virtual package to fftw-api and used versioned interface.
- all commands (except `spack find`, through `ConstraintAction`) now go
through get_env() to get the active environment
- ev.active was hard to read -- and the name wasn't descriptive.
- rename it to _active_environment to be more descriptive and to strongly
indicate that spack.environment manages it
- to aovid changing spec hashes drastically, only add this attribute to
differentiated abstract specs.
- othherwise assume that read-in specs are concrete
- spack.yaml files in the current directory were picked up inconsistently
-- make this a sure thing by moving that logic into find_environment()
and moving find_environment() to main()
- simplify arguments to Spack command:
- remove short args for infrequently used commands (--pdb/-D, -P, -s)
- `spack -D` now forces an env with a directory
- The `Spec` class maintains a special `_patches_in_order_of_appearance`
attribute on patch variants, but it is was preserved when specs are
copied.
- This caused issues for some builds
- Add special logic to `Spec` to preserve this variant on copy
- TODO: in the long term we should get rid of the special variant and
make it the responsibility of one of the variant classes.
- split 'environment' section into 'environments' and 'modules'
- move location to 'query packages' section
- move cd to developer section
- --env-dir no longer has a short optino (was -E)
- -E now means "run without an environment" (no longer same as --env-dir)
- -D now means "run with this directory environment"
- remove short options for may infrequently used top-level commands
- `spack env status` used to show install status; consolidate that into
`spack find`.
- `spack env status` will still print out whether there is an active
environment
- uninstall now:
- restricts its spec search to the current environment
- removes uninstalled specs from the current environment
- reports envs that still need specs you're trying to uninstall
- removed spack env uninstall command
- updated tests
- moved get_env from cmd/env.py to environment.py
- spack install will now install into the active environment when no
arguments are provided. It looks:
1. at the command line
2. for a local spack.yaml file
3. for any currently activated environment
- `spack env create <name>` works as before
- `spack env create <path>` now works as well -- environments can be
created in their own directories outside of Spack.
- `spack install` will look for a `spack.yaml` file in the current
directory, and will install the entire project from the environment
- The Environment class has been refactored so that it does not depend on
the internal Spack environment root; it just takes a path and operates
on an environment in that path (so internal and external envs are
handled the same)
- The named environment interface has been hoisted to the
spack.environment module level.
- env.yaml is now spack.yaml in all places. It was easier to go with one
name for these files than to try to handle logic for both env.yaml and
spack.yaml.
- `spack env activate foo`: sets SPACK_ENV to the current active env name
- `spack env deactivate`: unsets SPACK_ENV, deactivates the environment
- added support to setup_env.sh and setup_env.csh
- other env commands work properly with SPACK_ENV, as with an environment
arguments.
- command-line --env arguments take precedence over the active
environment, if given.
- env.yaml is now meaningful; it contains authoritative user specs
- concretize diffs user specs in env.yaml and env.json to allow user to
add/remove by simply updating env.yaml
- comments are preserved when env.yaml is updated by add/unadd
- env.yaml can contain configuration and include external configuration
either from merged files or from config scopes
- there is only one file format to remember (env.yaml, no separate init
format)
- env.json is now env.lock, and it stores the *last* user specs to be
concretized, along with full provenance.
- internal structure was modified slightly for readability
- env.lock contains a _meta section with metadata, in case needed
- added more tests for environments
- env commands follow Spack conventions; no more `spack env foo install`
- add `SingleFileScope` to configuration, which allows us to pull config
sections from a single file.
- update `env.yaml` and tests to ensure that the env.yaml schema works
when pulling configurtion from the env file.
- Each schema now has a top-level `properties` and `schema` attribute.
- The `properties` is a fragment that can be included in other
jsonschemas, via Python, not via '$ref'
- Th `schema` is a complete `jsonschema` with `title` and `$schema`
properties.
- add a common argument for `-e/--env`
- modify the database to support queries on subsets of hashes
- allow `spack find` to be filtered by hashes in an environment
- logic used in `spack find` was hiding duplicate installations if their
hashes were different
- short hash doesn't work in this scenario, since specs are structurally
identical
- ConstraintAction always works on a DB query, so use the DAG hash to
ensure uniqueness
- `spack.environment` is now the home for most of the infrastructure
around Spack environments
- refactor `cmd/env.py` to use everything from spack.environment
- refactor the cmd/env test to use pytest and fixtures
- `spack.util.environment` is the new home for routines that modify
environment variables.
- This is to make room for `spack.environment` to contain new routines
for dealing with spack environments
- Instead of one method with all parsers, each subcommand gets two
functions: `setup_<cmd>_parser()` and `environment_<cmd>()`
- the `setup_parser()` and `env()` functions now generate the parser
based on these and a list of subcommands.
- it is now easier to associate the arguments with the subcommand.
* modified tutorial packages
* update hint in hdf5 tutorial file (typo for suggested argument)
* add repo.yaml to tutorial repository
* update tutorial docs to refer user to tutorial package repository
* flake edits
* recommend site scope vs. defaults
* you don't specify the repo's name when adding a repo, just the path
* omit symlinks and create file copies when making a binary cache of a package
* unrelated flake edits involving regexes that recent flake is now angry about
* Record stdout for packages without errors
Previously our reporter only stored stdout if something went wrong
while installing a package. This prevented us from properly reporting
on steps where everything went as expected.
* More robustly report all phases to CDash
Previously if a phase generated no output it would not be reported to CDash.
For example, consider the following output:
==> Executing phase: 'configure'
==> Executing phase: 'build'
This would not generate a report for the configure phase. Now it does.
* Add test case for CDash reporting clean builds
* Fix default directory for CDash reports
The default 'cdash_report' directory name was getting overwritten
by 'junit-report'.
* Upload the build phase first to CDash
Older versions of CDash expect Build.xml to be the first file uploaded
for any given build.
* Define cdash_phase before referring to it
fixes#9739
The non-daemonic pool relies heavily on implementation details of the
multiprocessing package. In this commit we provide an implementation
that fits recent python versions.
This allows installing software on a namespace basis by including ${NAMESPACE} in `install_path_scheme`. e.g.,
```
cat ~/.spack/config.yaml
config:
install_path_scheme:
"${ARCHITECTURE}/${NAMESPACE}/${COMPILERNAME}-${COMPILERVER}/${PACKAGE}-${VERSION}-${HASH}"
```
The 'static_to_shared_library' function takes a compiler Executable,
which is intended to be invoked with a list of arguments; the
arguments must be separated from their values in the list, given
the way that 'Executable.__call__' invokes the underlying executable.
'static_to_shared_library' was not doing this, which this commit fixes.
Clang has support for using different fortran compilers with the Clang executable.
Spack includes logic to select a compiler wrapper symlink which refers to the fortran executable (since some build systems depend on the name of the compiler, e.g. 'gfortran' or 'flang').
This selection was previously based on the architecture, and chose incorrectly in some situations (e.g. for clang/gfortran on Linux). This replaces architecture-based wrapper selection with a selection that is based on the name of the Fortran compiler executable.
* Unite Dockerfiles - add build/run/push scripts
* update docker documentation
* update .travis.yml
* switch to using a preprocessor on Dockerfiles
* skip building docker images on pull requests
* update files with copyright info
* tweak when travis builds for docker files are done
fixes#9624
merge_config_rules was using `strict=False` to check if a spec
satisfies a constraint, which loosely translates to "this spec has
no conflict with the constraint, so I can potentially add it to the
spec". We want instead `strict=True` which means "the spec satisfies
the constraint right now".
- #8773 made the default mode 0o777, which is what's documented but
mkdirp actually takes the OS default or umask by default
- revert to the Python default by default, and only set the mode when
asked explicitly.
#9100 added a warning message when a path extracted from a module file
did not appear to be a valid filesystem path. This check was applied
to a variable which could be a list of paths, which would erroneously
trigger the warning. This commit updates the check to run at the
actual point where the path has been extracted.
* Add a build_language config.yaml option which controls the language
of compiler messages
* build_language defaults to "C", in which case the compiler messages
will be in English. This allows Spack log parsing to detect and
highlight error messages (since the regular expressions to find
error messages are in English)
* The user can use the default language in their environment by setting
the build_language config variable to null or ''
- `spack license list-files`: list all files that should have license headers
- `spack license list-lgpl`: list files still under LGPL-2.1
- `spack license verify`: check that license headers are correct
- Added `spack license verify` to style tests
- 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
compilers.yaml can track a module that is needed for a compiler, but
Spack does not fill this in automatically. This adds a note to the
documentation informing the user how to do this.
If we do not specify libdir explicitly, Meson chooses something like
lib/x86_64-linux-gnu, which causes problems when trying to find libraries
and pkg-config files.
Spack packages installed using spack buildcache were not running
post-install hooks, which create module files and manage licenses
(if necessary).
This was already occurring for Spack packages installed with
spack install --use-cache
Spack can now be configured to assign permissions to the files installed by a package.
In the `packages.yaml` file under `permissions`, the attributes `read`, `write`, and `group` control the package permissions. These attributes can be set per-package, or for all packages under `all`. If permissions are set under `all` and for a specific package, the package-specific settings take precedence. The `read` and `write` attributes take one of `user`, `group`, and `world`.
packages:
all:
permissions:
write: group
group: spack
my_app:
permissions:
read: group
group: my_team
* Better default CLI arguments for CDash reporting
--log-format=cdash is now implied if you specify the --cdash-upload-url
option to spack install.
We also now default to writing CTest XML files to cdash_report/ when using
the CDash reporter if no --log-file argument was specified.
* Improved documentation on how to use the CDash reporter
* Push default flag handlers into module scope
* Preserve backwards compatibility of builtin flag handler names
Ensure Spack continues to work for packages using the `Package.env_flags` idiom and equivalent.
* update docs and tests to match
* Update packages to match new syntax
Fix two bugs with module file parsing:
* Detection of the CRAY_LD_LIBRARY_PATH variable was broken by #9100.
This fixes it and adds a test for it.
* For module names like "foo-bar/1.0", the associated PACKAGE_DIR
environment variable name would be "FOO_BAR_DIR", but Spack was not
parsing the components and not converting "-" to "_"
Fixes#9166
This is intended to reduce errors related to lock timeouts by making
the following changes:
* Improves error reporting when acquiring a lock fails (addressing
#9166) - there is no longer an attempt to release the lock if an
acquire fails
* By default locks taken on individual packages no longer have a
timeout. This allows multiple spack instances to install overlapping
dependency DAGs. For debugging purposes, a timeout can be added by
setting 'package_lock_timeout' in config.yaml
* Reduces the polling frequency when trying to acquire a lock, to
reduce impact in the case where NFS is overtaxed. A simple
adaptive strategy is implemented, which starts with a polling
interval of .1 seconds and quickly increases to .5 seconds
(originally it would poll up to 10^5 times per second).
A test is added to check the polling interval generation logic.
* The timeout for Spack's whole-database lock (e.g. for managing
information about installed packages) is increased from 60s to
120s
* Users can configure the whole-database lock timeout using the
'db_lock_timout' setting in config.yaml
Generally, Spack locks (those created using spack.llnl.util.lock.Lock)
now have no timeout by default
This does not address implementations of NFS that do not support file
locking, or detect cases where services that may be required
(nfslock/statd) aren't running.
Users may want to be able to more-aggressively release locks when
they know they are the only one using their Spack instance, and they
encounter lock errors after a crash (e.g. a remote terminal disconnect
mentioned in #8915).
When a Spack Executable was configured to capture stderr and the
process failed, the error messages of the process were discarded.
This made it difficult to understand why the process failed. The
exception is now updated to include the stderr of the process when
the Executable captures stderr.
Adds 'code' to the list of suffixes that are excluded from version
parsing of URLs, such that if a URL contains the string
'cistem-1.0.0-beta-source-code', a version X will substitute in to
produce a URL with cistem-X-source-code ('source' was already excluded).
The 'cistem' package version is updated to make use of this (and fix
a fetching bug with the cistem package). A unit test is added to check
this parsing case.
Improve Spack's parsing of module show to eliminate some false
positives (e.g. accepting MODULEPATH when it is in fact looking for
PATH). This makes the following changes:
* Updates the pattern searching for several paths to avoid the case
where they are prefixes of unwanted paths
* Adds a warning message when an extracted path doesn't exist (which
may help catch future module parsing bugs faster)
* Adds a test with the content mentioned in #9083
Spack originally handled environment modifications in the following
order:
1. clear environment variables
(unless Spack was invoked with --dirty)
2. apply spack-specific environment variable updates,
including variables set by Spack core like CC/PKG_CONFIG_PATH
and those set by installed dependencies (e.g. in
setup_dependent_environment)
3. load all external/compiler modules
1 and 2 were done together. This splits 1 into its own function and
imposes the following order for environment modifications:
1. clear environment variables
2. load all external/compiler modules
3. apply spack-specific environment variable updates
As a result, prepend-path actions taken by Spack (or installed Spack
dependencies) take precedence over prepend-path actions from compiler
and external modules. Additionally, when Spack (or a package
dependency) sets/unsets an environment variable, that will override
the actions of external/compiler modules.
* Add 'extra_env' argument to Executable.__call__: this will be added
to the environment but does not affect whether the current
environment is reused. If 'env' is not set, then the current
environment is copied and the variables from 'extra_env' are added
to it.
* MakeExecutable can take a 'jobs_env' parameter that specifies the
name of an environment variable used to set the level of parallelism.
This is added to 'extra_env' (so does not affect whether the current
environment is reused).
* CMake-based Spack packages set 'jobs_env' when executing the 'test'
target for make and ninja (which does not use -j)
Consolidate prefix calculation logic for intel packages into the
IntelPackage class.
Add documentation on installing Intel packages with Spack an
(alternatively) adding them as external packages in Spack.
The functions returning the default scope to be modified or listed
have been moved from spack.cmd to spack.config.
Lmod now writes the guessed core compiler in the default modify scope
instead of the 'site' scope.
closes#8916
Currently Spack ends with an error if asked to write lmod modules files
and the 'core_compilers' entry is not found in `modules.yaml`. After
this PR an attempt will be made to guess that entry and the site
configuration file will be updated accordingly.
This is similar to what Spack already does to guess compilers on first
run.
- Support for Python 3.3 isn't really needed, as nothing uses it as the
default system Python, and nearly everyone will have a newer Python 3
version installed.
#8223 replaced regex-based makefile target parsing with an invocation of
"make -q". #8818 discovered that "make -q" can result in an error for some
packages.
Also, the "make -q" strategy relied on interpreting the error code, which only
worked for GNU Make and not BSD Make (which was deemed acceptable at
the time). As an added bonus, this implementation ignores the exit code and
instead parses STDERR for any indications that the target does not exist; this
works for both GNU Make and BSD Make.
#8223 also updated ninja target detection to use "ninja -t targets". This does
not change that behavior but makes it more-explicit with "ninja -t targets all"
This also adds tests for detection of "make" and "ninja" targets.
Fixes#9001#8289 added support for install_tree and copy_tree to merge into an existing
directory structure. However, it did not properly handle relative symlinks and
also removed support for the 'ignore' keyword. Additionally, some of the tests
were overly-strict when checking the permissions on the copied files.
This updates the install_tree/copy_tree methods and their tests:
* copy_tree/install_tree now preserve relative link targets (if the symlink in the
source directory structure is relative, the symlink created in the destination
will be relative)
* Added support for 'ignore' argument back to copy_tree/install_tree (removed
in #8289). It is no longer the object output by shutil.ignore_patterns: you pass a
function that accepts a path relative to the source and returns whether that
path should be copied.
* The openfoam packages (currently the only ones making use of the 'ignore'
argument) are updated for the new API
* When a symlink target is absolute, copy_tree and install_tree now rewrite the
source prefix to be the destination prefix
* copy_tree tests no longer check permissions: copy_tree doesn't enforce
anything about permissions so its tests don't check for that
* install_tree tests no longer check for exact permission matching since it can add
file permissions
- `imp` is deprecated and seems to have started having some weird
issues on certain Linux versions.
- In particular, the file argument to `load_source` is ignored on
arch linux with Python 3.7.
- `imp` is the only way to do imports in 2.6, so we'll keep it around for
now and use it if importlib won't work.
- `importlib` is the new import system, and it allows us to get
lower-level access to the import implementation.
- This consolidates all import logic into `spack.util.imp`, and make it
use `importlib` if it's avialable.
Replace use of `shutil.copytree` with `copy_tree` and `install_tree` functions in `llnl.util.filesystem`.
- `copy_tree` copies without setting permissions. It should be used to copy files around in the build directory.
- `install_tree` copies files and sets permissions. It should be used to copy files into the installation directory.
- `install` and `copy` are analogous single-file functions.
- add more extensive tests for these functions
- update packages to use these functions.
- 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.

- cc cleanup caused a parsing regression in flag handling
- We added proper quoting to array expansions, but flag variables were
never actually converted to arrays. Old code relied on this.
This commit:
- Adds reads to convert flags to arrays.
- Makes the cc test check for improper space handling to prevent future
regressions.
- flags were prepended in reverse order to args, but this makes it hard
to see what order they'll be in on the final command line.
- add them in the order they'll appear to make cc easier to maintain.
- simplify code for assembling the command line
- fix separator used in SPACK_SYSTEM_DIRS test
- This corrects most of the issues found by shellcheck
- This also uses ':' as the delimiter for SPACK_SYSTEM_DIRS, for
consistency with other variables.
- filtering using sed causes most builds to slow down quite a bit, as the
compiler wrapper has to run sed many times, and *it* runs many times
- do the system directory parsing directly in bash
- Add tests to ensure that RPATHs are not added in cc mode, which can
cause some builds to fail.
- Change cc.py to use pytest style
- Instead of writing out all the flags, break the flags down into
variables so that it's easy to read what each test is supposed to
check. This should make cc.py more maintainable in the future.
- Adding -L and -Wl,-rpath to compile-only command lines ("cc mode" or
"-c") causes clang (if not also other compilers) to emit warnings that
confuse configure systems.
- Clang will print warnings about unused command-line arguments.
- This fix ensures that -L and -Wl,-rpath are not added if the compile
line is just building an object file with -c
- This also cleans up the cc script in several places.
Spack currently prepends include paths, library paths, and rpaths to the
compile line. This causes problems when a header or library in the package
has the same name as one exported by one of its dependencies. The
*dependency's* header will be preferred over the package's, which is not
what most builds expect. This also breaks some of our production codes.
This restores the original cc behavior (from *very* early Spack) of parsing
compiler arguments out by type (`-L`, `-I`, `-Wl,-rpath`) and reconstituting
the full command at the end.
`<includes> <other_args> <library dirs> <rpaths>`
This differs from the original behavior in one significant way, though: it
*appends* the library arguments so that dependency libraries do not shadow
those in the build.
This is safe because semantics aren't affected by *interleaving* `-I`, `-L`,
and `-Wl,-rpath` arguments with others, only with each other (so the order of
two `-L` args affects the search path, but we search for all libraries on the
command line using the same search path).
We preserve the following:
1. Any system directory in the paths will be listed last.
2. The root package's include/library/RPATH flags come before flags of the
same type for any dependency.
3. Order will be preserved within flags passed by the build (except system
paths, which are moved to be last)
4. Flags for dependencies will appear between the root flags and the system
flags, and the flags for any dependency will come before those for *its*
dependencies (this is for completeness -- we already guarantee this in
`build_environment.py`)
* Fix performance issue when compiling.
Spack was doing active wait when compiling, spoiling one core.
My fix consists in not setting any timeout for select, instead of
the previous 0 second.
* Fix comments about select.select timeout
- This was a nasty workaround due to the way our compiler wrappers used
to work. We don't want to have to modify our elfutils installation to
install libdwarf.
- Since cd9691de5, we no longer need this because the package will always
come before dependencies in our include order.

- previously, output could be confusing when deptypes were only shown for
one dependent when a node had *multiple* dependents
- also fix default coverage of `Spec.tree()`: it previously defaulted to
cover only build and link dependencies, but this is a holdover from
when those were the only types.
- 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.
Some packages do not have a `url` and are instead downloaded via `git`,
`hg`, or `svn`. Some packages like `spectrum-mpi` cannot be downloaded at
all, and are placeholder packages for system installations. Previously,
`__init__()` in `PackageBase` crashed if a package did not have a `url`
attribute defined.
I hacked this section of code out, but I have no idea what the
repercussions of that are.
- This hard-codes the hash lengths rather than computing them on import.
- Also cleans up the code in `spack.util.crypto` to make it easier to
understand.
Fix this output error:
```
$ spack -m module loads mpileaks
==> Error: `spack module loads -m t -m c -m l ...` has been moved. Try this instead:
$ spack module t loads mpileaks
$ spack module c loads mpileaks
$ spack module l loads mpileaks
```
In case a deprecated form of the module command is used, the program
will exit non-zero and print an informative error message suggesting
which command should be used instead.
As requested in the review all the commands meant to manage module
files have been grouped under the `spack module` command.
Unit tests have been refactored to match the new command structure.

This PR reverts the use of `spack module loads` in favor of
`spack module find` when loading module files via Spack. After this PR
`spack load` will accept a single spec at a time, and will be able
to interpret correctly the `--dependencies` option.
fixes#4400
The feature requested in #4400 was already part of the module file
configuration, but it was neither tested nor documented. This
commit takes care of adding a few lines in the documentation and a
regression test.
This just because the fixture has been moved one level above the one
it was originally defined. In this more general context there's more
than one configuration file that could be patched for tests.
'spack module' has been split into multiple commands, each one tied to a
specific module type. This permits the specialization of the new
commands with features that are module type specific (e.g. set the
default module file in lmod when multiple versions of the same package
are installed at the same time).
- repo membership test was broken by the refactor of spack/__init__.py
- refactor singleton so that 'spec in repo' works again for `spack.repo.path`
- fix spec command and add basic tests for `spack spec` and `spack spec --yaml`
- There was a lot of documentation in `PackageBase` dating back to the
very first versions of Spack.
- It was repetitive and out of date, and the docs at spack.readthedocs.io
are better.
- Remove the outdated specifics, and leave the minimal useful set of
developer docs in `package.py`.
- 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.
- Add command-line scope option to Spack
- Rework structure of main to allow configuration system to raise
errors more naturally

- Fixes a bug in `llnl.util.lock`
- Locks in the current directory would fail because the parent directory
was the empty string.
- Fix this and return '.' for the parent of locks in the current
directory.
Replace regex-based target detection for Makefiles with a preliminary "make -q"
to check if a target exists. This does not work for NetBSD make; additional work
is required to detect if NetBSD make is present and to use a regex in that case.
The affected makefile target checks are only performed when the "--test" flag is
added to a "spack install" invocation.
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.
Spack provides a number of classes based on commonly-used build systems
that users can extend when writing packages; the classes provide functionality
to perform the actions relevant to the build system (e.g. running "configure" for
an Autotools-based package). This adds documentation for classes supporting the
following build systems:
* Makefile
* Autotools
* CMake
* QMake
* SCons
* Waf
This includes build systems for managing extensions of the following packages:
* Perl
* Python
* R
* Octave
This also adds documentation on implementing packages that use a custom build
system (e.g. Perl/CMake).
Spack also provides extendable classes which aggregate functionality for related
sets of packages, e.g. those using CUDA. Documentation is added for
CudaPackage.
- The setup-env.sh script currently makes two calls to spack, but it
should only need to make one.
- Add a fast-path shell setup routine in `main.py` to allow the shell
setup to happen in a single, fast call that doesn't load more than it
needs to.
- This simplifies setup code, as it has to eval what Spack prints
- TODO: consider eventually making the whole setup script the output of a
spack command
* update help of `clean --all` to include `-p`
* remove old orphaned `.pyc` removal
* restrict removal or orphaned pyc files to `lib/spack` and `var/spack`
- Clean up error messages for when a lock can't be created, or when an
exclusive (write) lock can't be taken on a file.
- Add a number of subclasses of LockError to distinguish timeouts from
permission issues.
- Add an explicit check to prevent the user from taking a write lock on a
read-only file.
- We had a check for this for when we try to *upgrade* a lock on an RO
file, but not for an initial write lock attempt.
- Add more tests for different lock permission scenarios.
- write locks previously wrote information about the lock holder (host
and pid), and read locks woudl read this in.
- This is really only for debugging, so only enable it then
- add some tests that target debug info, and improve multiproc lock test
output
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.
If the user sets "ccache: true" in spack's config.yaml, Spack will use an available
ccache executable when compiling c/c++ code. This feature is disabled by default
(i.e. "ccache: false") and the documentation is updated with how to enable
ccache support
Functional updates:
- `python` now creates a copy of the `python` binaries when it is added
to a view
- Python extensions (packages which subclass `PythonPackage`) rewrite
their shebang lines to refer to python in the view
- Python packages in the same namespace will not generate conflicts if
both have `...lib/site-packages/namespace-example/__init__.py`
- These `__init__` files will also remain when removing any package in
the namespace until the last package in the namespace is removed
Generally (Updated 2/16):
- Any package can define `add_files_to_view` to customize how it is added
to a view (and at the moment custom definitions are included for
`python` and `PythonPackage`)
- Likewise any package can define `remove_files_from_view` to customize
which files are removed (e.g. you don't always want to remove the
namespace `__init__`)
- Any package can define `view_file_conflicts` to customize what it
considers a merge conflict
- Global activations are handled like views (where the view root is the
spec prefix of the extendee)
- Benefit: filesystem-management aspects of activating extensions are
now placed in views (e.g. now one can hardlink a global activation)
- Benefit: overriding `Package.activate` is more straightforward (see
`Python.activate`)
- Complication: extension packages which have special-purpose logic
*only* when activated outside of the extendee prefix must check for
this in their `add_files_to_view` method (see `PythonPackage`)
- `LinkTree` is refactored to have separate methods for copying a
directory structure and for copying files (since it was found that
generally packages may want to alter how files are copied but still
wanted to copy directories in the same way)
TODOs (updated 2/20):
- [x] additional testing (there is some unit testing added at this point
but more would be useful)
- [x] refactor or reorganize `LinkTree` methods: currently there is a
separate set of methods for replicating just the directory structure
without the files, and a set for replicating everything
- [x] Right now external views (i.e. those not used for global
activations) call `view.add_extension`, but global activations do not
to avoid some extra work that goes into maintaining external views. I'm
not sure if addressing that needs to be done here but I'd like to
clarify it in the comments (UPDATE: for now I have added a TODO and in
my opinion this can be merged now and the refactor handled later)
- [x] Several method descriptions (e.g. for `Package.activate`) are out
of date and reference a distinction between global activations and
views, they need to be updated
- [x] Update aspell package activations
- Spack was assuming that a group with gid == current uid would always exist.
- This was breaking the travis build for macos.
- also fix issue with the DB tarball test finding coverage filesx
- pytest was not reporing the correct version from pytest.__version__.
It reported 'unknown'
- this fixes issues on some systems where system-installed pytest plugins
would try to use the version and convert it to an int
The following improvements are made to cxx standard support
(e.g. compiler.cxxNN_flag functions) in compilers:
* Add cxx98_flag property
* Add support for throwing an exception when a flag is not supported (previously
if a flag was not supported the application was terminated with tty.die)
* The name of the flag associated with e.g. c++14 standard support changes for
different compiler versions (e.g. c++1y vs c++14). This makes a few corrections
on what flag to return for which version.
* Added tests to confirm that versions report expected flags for various c++
standards (or raise an exception for versions that don't provide a given cxx
standard)
Note that if a given cxx standard is the default, the associated flag property will
return ""; cxx98 is assumed to be the default standard so this is the behavior for
the associated property in the base compiler class.
Package changes:
* Improvements to the boost spec to take advantage of the improved standard
flag facility.
* Update the clingo spec to catch the new exception rather than look for an
empty flag to indicate non-support (which is not part of the compiler flag API)
Fixes#7885#7193 added the patches_to_apply function to collect patches which are then
applied in Package.do_patch. However this only collects patches that are
associated with the Package object and does not include Spec-related patches
(which are applied by dependents, added in #5476).
Spec.patches already collects patches from the package as well as those applied
by dependents, so the Package.patches_to_apply function isn't necessary. All
uses of Package.patches_to_apply are replaced with Package.spec.patches.
This also updates Package.content_hash to require the associated spec to be
concrete: Spec.patches is only set after concretization. Before this PR, it was
possible for Package.content_hash to be valid before concretizing the associated
Spec if all patches were associated with the Package (vs. being applied by
dependents). This behavior was unreliable though so the change is unlikely to
be disruptive.
Fixes#8345
Spack environment modifications are applied before modules are loaded; this
includes settings to CC, FC, F77, and CXX, which point to the Spack compiler
wrappers. If the loaded modules set CC, this overrides the Spack compiler
wrappers. This PR adds a context manager to preserve the values of CC etc. that
are set by Spack: any effects on the CC, FC, F77, and CXX variables from modules
are undone and their original values are restored.
* pybind11: test support
Add a test functionality to pybind11.

Some projects use non-CTest manual targets for tests.
* extend Prefix class with join() member to support dynamic directories
* add more tests for Prefix.join()
* more tests for Prefix.join()
* add docstring
* add example to docstring of Prefix class
* cleanup Prefix.join() tests
* use Prefix.join() in Packaging Guide
Fixes#8217
Trying to relocate a distribution when the new and old paths are
equal leads to failure, because the test that ensures that no
unrelocated bits are left over always fails. As an example, this
occurs if a user installs a package, generates a binary with it
using 'spack buildcache', uninstalls it, and then attempts to
reinstall into the same spack installation using the generated
binary package.
This updates the relocation check to accept the presence of the
old prefix in binaries if the package is being reinstalled into
its original location.
* allow user to constrain dependencies that are added conditionally
* remove check for not-visited deps from normalize, move it to concretize. The check now runs after the concretization loop completes (so an error is only reported if the user-mentioned spec doesnt appear anywhere in the dag)
* remove separate full_spec_deps variable; rename spec_deps to all_spec_deps to clarify that it merges user-specified dependencies with derived dependencies
* add unit test to confirm new functionality
- `spack config blame` is similar to `spack config get`, but it prints
out the config file and line number that each line of the merged
configuration came from.
- This is a debugging tool for understanding where Spack config settings
come from.
- add tests for config blame
Fixes: #8258#8090 altered import behavior so that import spack no longer
provides access to many other Spack modules. This addresses
a case which depended on the prior behavior and was not
updated as part of #8090. This particular import error only
came up when users were setting compiler flags on specs.
See also: #8194
- there were some leftover spack.* names being used after we removed
globals and moved everything in the top-level namespace to spack.pkgkit
- point those references to their new homes
- remove most `import spack` statements, except for files that need
`spack_version`
- import spack is no longer sufficient to use submodules
(e.g. spack.directives).
- these submodules must be imported directly. Update references
accordingly.
- Spack packages were originally expected to call `from spack import *`
themselves, but it has become difficult to manage imports in the
Spack core.
- the top-level namespace polluted by package symbols, and it's not
possible to avoid circular dependencies and unnecessary module loads in
the core, given all the stuff the packages need.
- This makes the top-level `spack` package essentially empty, save for a
version tuple and a version string, and `from spack import *` is now
essentially a no-op.
- The common routines and directives that packages need are now in
`spack.pkgkit`, and the import system forces packages to automatically
include this so that old packages that call `from spack import *`
will continue to work without modification.
- Since `from spack import *` is no longer required, we could consider
removing ``from spack import *`` from packages in the future and
shifting to ``from spack.pkgkit import *``, but we can wait a while to
do this.
- spack.util.lock behaves the same as llnl.util.lock, but Lock._lock and
Lock._unlock do nothing.
- can be disabled with a control variable.
- configuration options can enable/disable locking:
- `locks` option in spack configuration controls whether Spack will use filesystem locks or not.
- `-l` and `-L` command-line options can force-disable or force-enable locking.
- Spack will check for group- and world-writability before disabling
locks, and it will not allow a group- or world-writable instance to
have locks disabled.
- update documentation
- Spack core has long used llnl.util.filesystem.join_path, but
os.path.join is pretty much the same thing, and is more efficient.
- Use os.path.join in the core Spack code from now on.
- simplify the singleton pattern across the codebase
- reduce lines of code needed for crufty initialization
- reduce functions that need to mess with a global
- Singletons whose semantics changed:
- spack.store.store() -> spack.store
- spack.repo.path() -> spack.repo.path
- spack.config.config() -> spack.config.config
- spack.caches.fetch_cache() -> spack.caches.fetch_cache
- spack.caches.misc_cache() -> spack.caches.misc_cache
- `spack.cmd.all_commands` does a directory listing on
`lib/spack/spack/cmd`, regardless of whether it is needed
- make this lazy so that the directory listing won't happen unless it's
necessary.
- It turns out that jsonschema is one of the more expensive imports.
- move imports of jsonschema into functions to avoid the performance hits
for calls that don't need config.
- spack.store was previously initialized at the spack.store module level,
but this means the store has to be initialized on every spack call.
- this moves the state in spack.store to a singleton so that the store is
only initialized when needed.
- spack.repository module is now spack.repo
- `spack.repo` is now `spack.repo.path()` and loaded lazily
- Added `spack.repo.get()` and `spack.repo.all_package_names()` as
convenience functions to simplify the new lazy interface.
- updated tests and code
