The go team released 1.9.2 which includes fixes for some things
that 1.9.1 broke:
> ... include fixes to the compiler, linker, runtime, documentation, go command, and the crypto/x509, database/sql, log, and net/smtp packages. They include a fix to a bug introduced in Go 1.9.1 and Go 1.8.4 that broke "go get" of non-Git repositories under certain conditions.
This updates the logic for Package.extends so that if the spec
associated with the package is not concrete, it will report true if
the package *could extend* the given spec; generally speaking a
package could extend a spec as long as none of the details associated
with its extendee spec conflict with the given spec. When the spec
associated with the package is concrete, this function will only
report whether the package *does extend* the given spec. When both
the specs are concrete, the semantics are the same as before.
* Exodus: skip the -G "Unix Makefiles" part
The problem is that spack passes -G "Unix Makefiles" into cmake, which normally
works. But in the Exodus package, it is being passed into a bash wrapper
script. In there, the $@ then loses the information about "Unix Makefiles"
being just one argument, and in effect passes -G Unix Makefiles into the cmake
(without quotes), and so cmake only sees -G Unix, and then fails. This is a
known problem with bash with no simple solutions. As a workaround, this patch
skips the first two arguments, i.e., -G and "Unix Makefiles". This makes it
work.
Fixes#5895.
* Port exodusii to cmake
The cmake options were taken from the cmake-exodus bash script and ported to
spack directly.
* Use variant forwarding to forward the 'mpi'
Now instead of
spack install exodusii~mpi^netcdf~mpi^hdf5~mpi
one can just use
spack install exodusii~mpi
* When creating a tar of a package for a build cache, symlinks are
preserved (the corresponding path in the newly-created tarfile will
be a symlink rather than a copy of the file)
* Dont add external packages to a build cache
* When installing from binary cache, don't create install prefix until
verification is complete
* sw4lite: fix build errors and add variants
* sw4lite: change linking against blas and lapack
* change order of blas and lapack
* satisfy flake8 requirements
* Update package.py
* Add the custom paraview lib directory structure to the library paths in the paraview module file.
* Fixing flake8 issues.
* Checking if lib64 exists for paraview module file generation, else use lib.
* Fixing more flake8 problems I introduced.
Since LLVM 3.9 Clang can use the libc++ library by default using the
CLANG_DEFAULT_CXX_STDLIB cmake configuration variable, without having to
specify the -stdlib=libc++ option on the clang++ command line.
This commit makes clang++ use libc++ by default for LLVM 3.9 and later if the
libcxx variant is on.
Fixes#5942.
* Fixes#5754
Previously when RepoPath.repo_for_pkg was invoked with a string,
it did not check if the string included a namespace. Any
namespace-qualified package provided as a string would not be found
(at which point the behavior was to return the highest-precedence
repository).
* handle nested namespaces for packages specified as strings in repo_for_pkg
* add preliminary repository tests
* add test which replicates #5754
* refactor repo tests with fixtures
* define repo_path equivalent at test-level scope for repo tests
* add tests for unknown namespace/package
* rename fixture function (no longer prefixed with 'test_')
Internally we work against a branch named 'llnl/develop', which
mirrors the public repository's `develop` branch.
It's useful to be able to run flake8 on our changes, using
`llnl/develop` as the base branch instead of `develop`.
Internally the flake8 subcommand generates the list of changes files
using a hardcoded range of `develop...`.
This makes the base of that range a command line option, with a
default of `develop`.
That lets us do this:
```
spack flake8 --base llnl/develop
```
which uses a range of `llnl/develop...`.
Chasing a performance regression has lead me to this change, going from default optimization gives a significant performance win. The sweet spot for zlib is apparently `-O2`, both `-Ofast` and `-O3` are slightly worse (regression is about 3% compared with `-O2) in my testing.
Happy to share my methodology with people so we can benchmark on a wider variety of systems.
