- Stage and fetcher were not being set up properly when fetching using
a different fetch strategy than the default one for the package.
- This is fixed but fetch/stage/mirror logic is still too complicated
and long-term needs a rethink.
- Spack will now print a warning when fetching a checksum-less tarball
from a mirror -- users should be careful to use https or local
filesystem mirrors for this.
Versions found by wildcard URLs are different from versions found by
parse_version, etc. The wildcards are constructed more haphazardly
than the very specific URL patterns in url.py, so they can get things
wrong. e.g., for this URL:
https://software.lanl.gov/MeshTools/trac/attachment/wiki/WikiStart/mstk-2.25rc1.tgz
We miss the 'rc' and only return 2.25r as the version if we ONLY use
URL wildcards.
Future: Maybe use the regexes from url.py to scrape web pages, and
then compare them for similarity with the original URL, instead of
trying to make a structured wildcard URL pattern? This might yield
better results.
- remove getcwd() check (seems arbitrary -- if users set their TMPDIR
to this why stop them?)
- try a number of common locations and try per-user directories in
them first.
- Adding `preferred=True` to a version directive will change its sort
order in concretization.
- This provides us a rudimentary ability to keep the Spack stack
stable as new versions are added.
- Having multiple stacks will come next, but this at least allows us
to specify default versions of things instead of always taking the
newest.
This changes the compiler wrappers so that they are called by the same
name as the wrapped compiler. Many builds make assumptions about
compiler names, and we need the spack compilers to be recognizable so
that build systems will get their flags right.
This adds per-compiler subdirectories to lib/spack/spack/env directory
that contain symlinks to cc for the C, C++, F77, and F90
compilers. The build now sets CC, CXX, F77, and F90 to point to these
links instead of to the generically named cc, c++, f77, and f90
wrappers.
- Extension logic didn't take conditional deps into account.
- Extension methods now check for whether the extnesion is
in the extendee map AND whether the dependency is actually present
in the spec yet.
