Symlinks on Windows can use longpath prefixes (\\?\); these are fine
in the context of win32 API interactions but break numerous facets of
Spack behavior that rely on string parsing/matching (archiving,
binary distributions, tarball extraction, view regen, etc).
Spack's internal readlink method (llnl.util.symlink.readlink)
gracefully handles this by removing the prefix and otherwise behaving
exactly as os.readlink does, so we should prefer that in all cases.
Use correct path separator in get_all_package_diffs for all platforms.
Ensures correct package change computation on Windows when pruning unchanged specs in Gitlab CI
Before this PR, if Spack could see a possibility to reuse a spec that
doesn't match a strong preference, it would do so. After the PR, a
strong preference would take precedence.
avoid calling `spec.target` when None.
When an external compiler package has an `os` set but no `target` set, Spack
currently falls into a codepath that calls `spec.target` (which itself calls
`spec.architecture.target.Microarchitecture`) when `spec.architecture.target`
is None, throwing an error.
e.g.
```
packages:
gcc:
externals:
- spec: gcc@12.3.1 os=rhel7
prefix: /usr
```

Instead, enforce consistency using the "gl" virtual that allows
only one provider.

* e4s-power: remove redundant paraview
* Pipelines: update osmesa variants
* trilinos-catalyst-ioss-adapter: make gl a run dependency
* Remove mesa18 and libosmesa
mesa18 was introduced in #19528 as a way to maintain the old
autotools build of mesa separate from the new meson build.
We could add a second build system to mesa, but since mesa18 has
been deprecated for a long time, we'll just remove it.
libosmesa was used to multiplex the gl provider between mesa18
and mesa, and is thus unecessary. Remove it to reduce complexity
in the graphical stack.
* Remove references to mesa18 and libosmesa
* vtk: rework dependency on gl and osmesa
* memsurfer: rework dependency on vtk
* visit: minimal fix to avoid having both osmesa and glx
`glibc` and `musl` provide a basic implementation of `iconv` (`iconv`,
`iconv_open`, `iconv_close`), but in practice the installation may be
missing the character encoding methods to make them usable. On Fedora
for example, users need to
```yum install glibc-gconv-extra```
to get the character encodings that `gettext` requires during configure,
namely EUC-JP. Users may not have permissions to install the missing
parts of glibc.
Since Spack can install `libiconv`, it is simpler to use that by
default.
This fixes a bug occurring when two root specs need to select
old versions, and these versions have the same penalty in the
optimization. This sometimes caused an older version to be
preferred to a more recent one.
The issue was the omission of `PackageNode` in the optimization
tuple.
This fixes an issue where ghcr, gitlab and possibly other container registries paginate tags by default, which violates the OCI spec v1.0, but is common practice (the spec was broken itself). After this commit, you can create build cache indices of > 100 specs on ghcr.

* py-matplotlib: qualify when to do a post install
Older versions of py-matplotlib don't seem to have some of the
files that the post install step is trying to install.
Looks like the files first appeared in 3.6.0 and later.

Apparently urllib can throw a range of different exceptions:
1. HTTPError
2. URLError with e.reason set to the actual exception
3. TimeoutError from getresponse, which is not wrapped
GCC C++ headers like cstdlib use `#include_next <stdlib.h>` to wrap libc
headers. We're using `-isystem` for libc, which puts those headers too
early in the search path. `-idirafter` fixes this so `include_next`
works.
Add the ability to include any number of (potentially nested) concrete environments, e.g.:
```yaml
spack:
specs: []
concretizer:
unify: true
include_concrete:
- /path/to/environment1
- /path/to/environment2
```
or, from the CLI:
```console
$ spack env create myenv
$ spack -e myenv add python
$ spack -e myenv concretize
$ spack env create --include-concrete myenv included_env
```
The contents of included concrete environments' spack.lock files are
included in the environment's lock file at creation time. Any changes
to included concrete environments are only reflected after the environment
is re-concretized from the re-concretized included environments.
- [x] Concretize included envs
- [x] Save concrete specs in memory by hash
- [x] Add included envs to combined env's lock file
- [x] Add test
- [x] Update documentation

Currently SPACK_COLOR=always is not respected in the build process on
macOS, because the global `_force_color` is re-evaluated in global scope
during module setup, where it is always `None`.
So, move global init bits from main.py to the module itself.
Some specs which were excluded from reuse,
are currently added back to the solve when
we traverse dependencies of other reusable
specs.
This fixes the issue by keeping track of what
we can explicitly reuse.
This commit adds a layer of indirection to improve build isolation with
and without external Python, as well as usability of environment views.
It adds `python-venv` as a dependency to all packages that `extends("python")`,
which has the following advantages:
1. Build isolation: only `PYTHONPATH` is considered in builds, not
user / system packages
2. Stable install layout: fixes the problem on Debian, RHEL and Fedora where
external / system python produces `bin/local` subdirs in Spack install prefixes.
3. Environment views are Python virtual environments (and if you add
`py-pip` things like `pip list` work)
Views work whether they're symlink, hardlink or copy type.
This commit additionally makes `spec["python"].command` return
`spec["python-venv"].command`. The rationale is that packages in repos we do
not own do not pass the underlying python to the build system, which could still
result in incorrectly computed install layouts.
Other attributes like `libs`, `headers` should be on `python` anyways and need no change.
