- `spack spec` now returns an error if given no specs
- removed superfluous trailing newline from `spack spec --yaml` output
(only one newline now)
|
|
|
|
- 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.
|

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 fo 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`)

fixes #8736
|
|
The `--dependencies` and `--exclude` flags are now arguments to the `spack view`
comand rather than the `spack view symlink` command.
|
|
- 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.
|
|
- this test is checking the package *repository*, not the database.
|
|
- 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
|
|
- ensure that packages can't have more than one of git, hg, svn, or url
|
|
|
|
- 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.

fixes #6321

fixes #2215
fixes #2570
fixes #6676
fixes #7281
closes #3827
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.
|

|
Added a subcommand that sets the default module to be loaded, if
multiple installations of the same package are present.
|
|
'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.
|
|
- two stage tests weren't properly using the mutable_config fixture.
- this caused running `spack test` to modify the user's config.yaml

- Add command-line scope option to Spack
- Rework structure of main to allow configuration system to raise
errors more naturally
Co-authored-by: Todd Gamblin <tgamblin@llnl.gov>
|
|
- 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.
