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.
fixes#2215fixes#2570fixes#6676fixes#7281closes#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.
'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

- 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.
