We've been doing this for quite a while now, and it does not seem to
cause issues.
- [x] Switch the noisy warning to a debug to make Spack a bit quieter
while building.
* Added architecture specific optimization flags for Clang / LLVM
* Disallow compiler optimizations for mixed toolchains
* We emit a warning when building for a mixed toolchain
* Fixed issues with suffixed versions of compilers; Apple's Clang will,
for the time being, fall back on x86-64 for every compilation.
* DataSpaces: 1.8.0
Add a newer release of DataSpaces for ADIOS2.
Also add missing `-fPIC` flags since this is a static library.
* ADIOS2: Dataspaces, libffi, libfabric
Add missing dependencies to ADIOS2. Without explicit control,
those dependencies might get picked up from the system environment
and will cause unstable builds.
* Hide transitive SST dependencies
* ADIOS2: Simplify SST CMake Flags
As proposed by Chuck
* Methods setting the environment now do it separately for build and run
Before this commit the `*_environment` methods were setting
modifications to both the build-time and run-time environment
simultaneously. This might cause issues as the two environments
inherently rely on different preconditions:
1. The build-time environment is set before building a package, thus
the package prefix doesn't exist and can't be inspected
2. The run-time environment instead is set assuming the target package
has been already installed
Here we split each of these functions into two: one setting the
build-time environment, one the run-time.
We also adopt a fallback strategy that inspects for old methods and
executes them as before, but prints a deprecation warning to tty. This
permits to port packages to use the new methods in a distributed way,
rather than having to modify all the packages at once.
* Added a test that fails if any package uses the old API
Marked the test xfail for now as we have a lot of packages in that
state.
* Added a test to check that a package modified by a PR is up to date
This test can be used any time we deprecate a method call to ensure
that during the first modification of the package we update also
the deprecated calls.
* Updated documentation
Python 3 metaclasses have a `__prepare__` method that lets us save the
class's dictionary before it is constructed. In Python 2 we had to walk
up the stack using our `caller_locals()` method to get at this. Using
`__prepare__` is much faster as it doesn't require us to use `inspect`.
This makes multimethods use the faster `__prepare__` method in Python3,
while still using `caller_locals()` in Python 2. We try to reduce the
use of caller locals using caching to speed up Python 2 a little bit.
Our importer was always parsing from source (which is considerably
slower) because the source size recorded in the .pyc file differed from
the size of the input file.
Override path_stats in the prepending importer to fool it into thinking
that the source size is the size *with* the prepended code.
Since the backup file is only created on the first invocation, it will
contain the original file without any modifications. Further invocations
will then read the backup file, effectively reverting prior invocations.
This can be reproduced easily by trying to install likwid, which will
try to install into /usr/local. Work around this by creating a temporary
file to read from.
* This updates stage names to use "spack-stage-" as a prefix.
This avoids removing non-Spack directories in "spack clean" as
c141e99 did (in this case so long as they don't contain the
prefix "spack-stage-"), and also addresses a follow-up issue
where Spack stage directories were not removed.
* Spack now does more-stringent checking of expected permissions for
staging directories. For a given stage root that includes a user
component, all directories before the user component that are
created by Spack are expected to match the permissions of their
parent; the user component and all deeper directories are expected
to be accessible to the user (read/write/execute).
This feature generates a verification manifest for each installed
package and provides a command, "spack verify", which can be used to
compare the current file checksums/permissions with those calculated
at installed time.
Verification includes
* Checksums of files
* File permissions
* Modification time
* File size
Packages installed before this PR will be skipped during verification.
To verify such a package you must reinstall it.
The spack verify command has three modes.
* With the -a,--all option it will check every installed package.
* With the -f,--files option, it will check some specific files,
determine which package they belong to, and confirm that they have
not been changed.
* With the -s,--specs option or by default, it will check some
specific packages that no files havae changed.
