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.
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One of the two is also outdated, since the issue has been solved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.
When you install Spack from a tarball, it will always show an exact
version for Spack itself, even when you don't download a tagged commit:
```
$ wget -q https://github.com/spack/spack/archive/refs/heads/develop.tar.gz
$ tar -xf develop.tar.gz
$ ./spack-develop/bin/spack --version
0.16.2
```
This PR sets the Spack version to `0.18.0.dev0` on develop, following [PEP440](https://github.com/spack/spack/pull/25267#issuecomment-896340234) as
suggested by Adam Stewart.
```
spack (fix/set-dev-version)$ spack --version
0.18.0.dev0 (git 0.17.1-1526-e270464ae0)
spack (fix/set-dev-version)$ mv .git .git_
spack $ spack --version
0.18.0.dev0
```
- [x] Update the release guide
- [x] Add __version__ to spack's __init__.py
- [x] Use PEP 440 canonical version strings
- [x] Make spack --version output [actual version] (git version)

* Add tests to ensure google cloud storage urls work as mirrors
This commit adds two tests to track that GCS buckets can work as
mirrors, and can be parsed as valid URLs.
Currently, gs:// format URLs are not correctly parsed.
* Fix URL parsing for GCS buckets
This commit adds GCS bucket URLs as valid URLs.
* lower priority of package-provided urls
This change favors urls found in a scraped page over those provided by
the package from `url_for_version`. In most cases this doesn't matter,
but R specifically returns known bad URLs in some cases, and the
fallback path for a failed fetch uses `fetch_remote_versions` to find a
substitute. This fixes that problem.
fixes#29204
* consider what links actually exist in all cases
Checksum was only actually scraping when called with no versions. It
now always scrapes and then selects URLs from the set of URLs known to
exist whenever possible.
fixes#25831
* bow to the wrath of flake8
* test-fetch urls from package, prefer if successful
* Update lib/spack/spack/package.py
Co-authored-by: Seth R. Johnson <johnsonsr@ornl.gov>
* reword as suggested
* re-enable mypy specific ignore and ignore pyflakes
* remove flake8 ignore from .flake8
* address review comments
* address comments
* add sneaky missing substitute
I missed this one because we call substitute on a URL that doesn't
contain a version component. I'm not sure how that's supposed to work,
but apparently it's required by at least one mock package, so back in it
goes.

Adds `spack external read-cray-manifest`, which reads a json file that describes a set of package DAGs. The parsed results are stored directly in the database. A user can see these installed specs with `spack find` (like any installed spec). The easiest way to use them right now as dependencies is to run `spack spec ... ^/hash-of-external-package`.
Changes include:
* `spack external read-cray-manifest --file <path/to/file>` will add all specs described in the file to Spack's installation DB and will also install described compilers to the compilers configuration (the expected format of the file is described in this PR as well including examples of the file)
* Database records now may include an "origin" (the command added in this PR registers the origin as "external-db"). In the future, it is assumed users may want to be able to treat installs registered with this command differently (e.g. they may want to uninstall all specs added with this command)
* Hash properties are now always preserved when copying specs if the source spec is concrete
* I don't think the hashes of installed-and-concrete specs should change and this was the easiest way to handle that
* also specs that are concrete preserve their `.normal` property when copied (external specs may mention compilers that are not registered, and without this change they would fail in `normalize` when calling `validate_or_raise`)
* it might be this should only be the case if the spec was installed
- [x] Improve testing
- [x] Specifically mark DB records added with this command (so that users can do something like "uninstall all packages added with `spack read-external-db`)
* This is now possible with `spack uninstall --all --origin=external-db` (this will remove all specs added from manifest files)
- [x] Strip variants that are listed in json entries but don't actually exist for the package

This PR removes a few outdated sections from the "Basics" part of the
documentation. It also makes a few topic under the environment section
more prominent by removing an unneeded spack.yaml subsection and
promoting everything under it.
Consolidate Spack's internal filepath logic to a select
few places and refactor to consistent internal useage of
os.path utilities. Creates a prefix, and a series of utilities
in the path utility module that facilitate handling paths
in a platform agnostic manner.

Update Installer CI
Co-authored-by: John Parent <john.parent@kitware.com>
Made the vcvars batch script location a member variable of the msvc compiler subclass, initialized from the compiler executable path. Added a setup_custom_environment() method to the msvc subclass that sources the vcvars script, dumps the environment, and copies the relevant environment variables to the Spack environment. Added class variables to the Windows OS and MSVC compiler subclasses to enable finding the compiler executables and determining their versions.
* Fixed path and uid issues.
* Added needed import statement; kluged .exe extension.
* Got package to build. Some manual intervention necessary, including sourcing the MSVC setup script and having certain configuration parameters.
* Removed CMake executable suffix hack.
To provide Windows-compatible functionality, spack code should use
llnl.util.symlink instead of os.symlink. On non-Windows platforms
and on Windows where supported, os.symlink will still be used.

fixes#29446
The new setup_*_environment functions have been falling back
to calling the old functions and warn the user since #11115.
This commit removes the fallback behavior and any use of:
- setup_environment
- setup_dependent_environment
in the codebase
Change the internal representation of `Spec` to allow for multiple dependencies or
dependents stemming from the same package. This change permits to represent cases
which are frequent in cross compiled environments or to bootstrap compilers.
Modifications:
- [x] Substitute `DependencyMap` with `_EdgeMap`. The main differences are that the
latter does not support direct item assignment and can be modified only through its
API. It also provides a `select_by` method to query items.
- [x] Reworked a few public APIs of `Spec` to get list of dependencies or related edges.
- [x] Added unit tests to prevent regression on #11983 and prove the synthetic construction
of specs with multiple deps from the same package.
Since #22845 went in first, this PR reuses that format and thus it should not change hashes.
The same package may be present multiple times in the list of dependencies with different
associated specs (each with its own hash).
* environment.py: allow link:run
Some users want minimal views, excluding run-type dependencies, since
those type of dependencies are covered by rpaths and the symlinked
libraries in the view aren't used anyways.
With this change, an environment like this:
```
spack:
specs: ['py-flake8']
view:
default:
root: view
link: run
```
includes python packages and python, but no link type deps of python.
