A user may want to set some attributes on a package without actually modifying the package (e.g. if they want to git pull updates to the package without conflicts). This PR adds a per-package configuration section called "set", which is a dictionary of attribute names to desired values. For example:
packages:
openblas:
package_attributes:
submodules: true
git: "https://github.com/myfork/openblas"
in this case, the package will always retrieve git submodules, and will use an alternate location for the git repo.
While git, url, and submodules are the attributes for which we envision the most usage, this allows any attribute to be overridden, and the acceptable values are any value parseable from yaml.
Newer versions of the CrayPE for EX systems have standalone compiler executables for CCE and compiler wrappers for Cray MPICH. With those, we can treat the cray systems as part of the linux platform rather than having a separate cray platform.
This PR:
- [x] Changes cray platform detection to ignore EX systems with Craype version 21.10 or later
- [x] Changes the cce compiler to be detectable via paths
- [x] Changes the spack compiler wrapper to understand the executable names for the standalone cce compiler (`craycc`, `crayCC`, `crayftn`).
For some instances of externally-provided Python (e.g. Homebrew),
the LDLIBRARY/LIBRARY config variables don't actually refer to
libraries and should therefore be excluded from ".libs".
Only enable the hdf5-vfd-gds package if it can compile.
- hdf5-vfd-gds needs cuda@11.7.1+ to be able to `find_library` for cuFile.
- Only enable hdf5-vfd-gds in the sdk if cuda@11.7.1+ is available.
If an earlier version of cuda is being used, do not depend on the
hdf5-vfd-gds package at all.

Whenever the rpath string actually _grows_, it falls back to patchelf,
when it stays the same length or gets shorter, we update it in-place,
padded with null bytes.
This PR only deals with absolute -> absolute rpath replacement. We don't
use `_build_tarball(relative=True)` in our CI. If `relative` then it falls
back to the old replacement code.
With this PR, relocation time goes down significantly, likely because patchelf
does some odd things with mmap, causing lots of overhead. Example:
- `binutils`: 700MB installed, goes from `1.91s` to `0.57s`, or `3.4x` faster.
Relocation time: 27% -> 10% of total install time
- `llvm`: 6.8GB installed, goes from `28.56s` to `5.38`, or `5.3x` faster.
Relocation time: 44% -> 13% of total install time
The bottleneck is now decompression.
Note: I'm somewhat confused about the "relative rpath" code paths. Right
now this PR only deals with absolute -> absolute replacement. As far as
I understand, if you embrace relative rpaths when uploading to the
buildcache, the whole point is you _don't_ want to patch rpaths on
install? So it seems fine to not expand `$ORIGIN` again imho.
When a package asks for non-parallel make, we need to force `make -j1` because just doing `make` will run in parallel under jobserver (e.g. `spack env depfile`).
We now always add `-j1` when asked for a non-parallel execution (even if there is no jobserver).
And each `MakeExecutable` can now ask for jobserver support or not. For example: the default `ninja` does not support jobserver so spack applies the default `-j`, but `ninja@kitware` or `ninja-fortran` does, so spack doesn't add `-j`.
Tips: you can run `SPACK_INSTALL_FLAGS=-j1 make -f spack-env-depfile.make -j8` to avoid massive job-spawning because of build tools that don't support jobserver (ninja).

We try to avoid non-default variant values in the concretizer, but this doesn't make
sense for variants forced to take some non-default value by variant propagation.
Counting this as a penalty effectively biases the concretizer for small specs dependency
graphs -- something we try very hard to avoid elsewhere because it can lead to very
strange decisions.
Example: with the penalty, `spack spec hdf5` will choose the default `openmpi` as its
`mpi` provider, but `spack spec hdf5 ~~shared` will choose `mpich` because it has to set
fewer non-default variant values because `mpich`'s DAG is smaller. That's not a good
reason to prefer a non-default virtual provider.
To fix this, if the user explicitly requests a non-default value to be propagated, there
shouldn't be a penalty. Variant values set on the CLI already don't count as default; we
just need to extend that to propagated values.
Adds another post install hook that loops over the install prefix, looking for shared libraries type of ELF files, and sets the soname to their own absolute paths.
The idea being, whenever somebody links against those libraries, the linker copies the soname (which is the absolute path to the library) as a "needed" library, so that at runtime the dynamic loader realizes the needed library is a path which should be loaded directly without searching.
As a result:
1. rpaths are not used for the fixed/static list of needed libraries in the dynamic section (only for _actually_ dynamically loaded libraries through `dlopen`), which largely solves the issue that Spack's rpaths are a heuristic (`<prefix>/lib` and `<prefix>/lib64` might not be where libraries really are...)
2. improved startup times (no library search required)
Untouched spec pruning was added to reduce the number of specs
developers see getting rebuilt in their PR pipelines that they
don't understand. Because the state of the develop mirror lags
quite far behind the tip of the develop branch, PRs often find
they need to rebuild things untouched by their PR.
Untouched spec pruning was previously implemented by finding all
specs in the environment with names of packages touched by the PR,
traversing in both directions the DAGS of those specs, and adding
all dependencies as well as dependents to a list of concrete specs
that should not be considered for pruning.
We found that this heuristic results in too many pruned specs, and
that dependents of touched specs must have all their dependencies
added to the list of specs that should not be considered for pruning.
* SEACAS: Update package.py to handle new SEACAS project name
The base project name for the SEACAS project has changed from
"SEACASProj" to "SEACAS" as of @2022-10-14, so the package
needed to be updated to use the new project name when needed.
The refactor also changes several:
"-DSome_CMAKE_Option:BOOL=ON"
to
define("Some_CMAKE_Option", True)
* SEACAS: Additional refactorings
* Replaced all cmake "-Dsomething=other" lines with either `define`
or `define_from_variant` functions.
Consolidated the application (fortran, legacy, all) enabling lines
into loops over the code names. Easier to see categorization of
applications and also to add/move/remove an application
Reordered some lines; general cleanup and restructuring.
* Address flake8 issues
* Remove trailing whitespace
* Reformat using black
