Reduces the number of stat calls to a bare minimum:
- Single pass over src prefixes
- Handle projection clashes in memory
Symlinked directories in the src prefixes are now conditionally
transformed into directories with symlinks in the dst dir. Notably
`intel-mkl`, `cuda` and `qt` has top-level symlinked directories that
previously resulted in empty directories in the view. We now avoid
cycles and possible exponential blowup by only expanding symlinks that:
- point to dirs deeper in the folder structure;
- are a fixed depth of 2.
* py-cffi: add compiler flags to fix build with clang
For %clang@13.0.1, this avoids the
```
clang-13: warning: optimization flag '-ffat-lto-objects' is not supported [-Wignored-optimization-argument]
```
warning being turned into an error, and fixes this link error:
```
build/temp.linux-x86_64-3.10/c/_cffi_backend.o: file not recognized: file format not recognized
```
* style
Currently `old_root` is computed by reading the symlink at `self.root`.
We should be more defensive in removing it by checking that it is in the
same directory as the new root. Otherwise, in the worst case, when
someone runs `spack env create --with-view=./view -d .` and `view`
already exists and is a symlink to `/`, Spack effectively runs `rm -rf /`.
`file` was used to detect Python scripts with shebangs, so that the interpreter could be changed from <python prefix> to <view path>. With this change, we detect shebangs using Python instead, so that `file` is no longer required.
The number of commit characters in patch files fetched from GitHub can change,
so we should use `full_index=1` to enforce full commit hashes (and a stable
patch `sha256`).
Similarly, URLs for branches like `master` don't give us stable patch files,
because branches are moving targets. Use specific tags or commits for those.
- [x] update all github patch URLs to use `full_index=1`
- [x] don't use `master` or other branches for patches
- [x] add an audit check and a test for `?full_index=1`

Known issues reports only 2 issues, among the bugs reported on GitHub.
One of the two is also outdated, since the issue has been solved
with the new concretizer. Thus, this commit removes the section.
* This commit removes the Boost.with_default_variants to variants
that packages are precisely dependant upon. This is the first batch
of 20 packages with modified boost dependencies.
* Style fixes
* Tested bridger: works for gcc-4.9.3 and gcc-8.3.1
Commit 26ff443 made the Gitlab pipeline failing on develop
(while it was not failing in the original PR) due to errors in the
fetcher. This change preserves the new versions, but will give
some time for use to sync our tarball mirror for better reliability
* vecgeom: fix cuda arch
* vecgeom: change 'options' to 'args'
* vecgeom: add spec to locals
* vecgeom: suppress architecture specializations when cuda
