all_urls: add urls[0] for versions (#16435)
This adds the `url` alternative `urls` to `package.all_urls`. With
this addition, one can find again new versions with
`spack versions <package>` for packages that are populated with
from mixin mirror `urls`.

Example: `util-macros` from x.org mixin.

Testing: fix unintended interactions between tests, part 2 (#16429)
This fixes some errors with setting up test configuration. These
errors do not cause current Spack tests to fail but do create
red herring issues elsewhere (see #15666). Fixing these errors
leads to more errors in tests that depended on the original
misconfigured state, so those are also addressed here.

This is an update to #16003 which accounts for some unit tests with
conflicting config/mutable_config fixtures. These conflicts were
not exposed until the mutable_config fixture was fixed. Details are
included below. The change which builds on #16003 is prefixed with
"(new)".

* For tests that use the real Spack package repository, the config
  needs to avoid using MPI providers that are not intended to be
  installed by Spack. Without this, it is possible that Spack tests
  which concretize the MPI virtual will end up trying to use an
  implementation that it shouldn't (e.g. one that is always
  provided externally). See #15666 for an example.
* The mutable_config test fixture was not initializing the scope
  roots to the right directories (so the resulting config was empty).
* The current_host fixture in the concretize.py tests was using the
  config fixture rather than mutable_config, and was polluting the
  config cache for other tests.
* One test in concretize.py was clearing a nonexistent cache
  (PackagePrefs._packages_config_cache). This reference has been
  removed.
* The test 'test_preferred_compilers' was was depending on cross
  test config pollution to succeed. The initial spec before
  concretization has been updated to updated to be explicit about
  the desired result.
* (new) For tests that use install_mockery and mutable_config,
  replace install_mockery with a separate install_mockery_mutable_config
  fixture that is exactly the same as install_mockery but uses the
  mutable_config fixture to avoid conflicts.

bugfix: spack shouldn't fail in an incomplete environment (#16473)
Fixed #15884.

Spack asks every package linked into an environment to tell us how
environment variables should be modified when a spack environment is
activated. As part of this, specs in an environment are symlinked into
the environment's view (see #13249), and the package calculates
environment modifications with *the default view as the prefix*.

All of this works nicely for pointing the user's environment at the view
*if* every package is successfully linked. Unfortunately, right now we
only track what specs "should" be in a view, not which specs actually
are. So we end up calculating environment modifications on things that
aren't linked into thee view, and the exception isn't caught, so lots of
spack commands end up failing.

This fixes the issue by ignoring and warning about specs where
calculating environment modifications fails. So we can still keep using
Spack even if the current environment is incomplete.

We should probably also just avoid computing env modifications *entirely*
for unlinked packages, but right now that is a slow operation (requires a
lot of YAML parsing). We should revisit that when we have some better
state management for views, but the fix adopted here will still be
necessary, as we want spack commands to be resilient to other types of
bugs in `setup_run_environment()` and friends. That code is in packages
and we have to assume it could be buggy when we call it outside of builds
(as it might fail more than just the build).

Automatically find externals (#15158)
Add a `spack external find` command that tries to populate
`packages.yaml` with external packages from the user's `$PATH`. This
focuses on finding build dependencies. Currently, support has only been
added for `cmake`.

For a package to be discoverable with `spack external find`, it must define:
  * an `executables` class attribute containing a list of
    regular expressions that match executable names.
  * a `determine_spec_details(prefix, specs_in_prefix)` method

Spack will call `determine_spec_details()` once for each prefix where
executables are found, passing in the path to the prefix and the path to
all found executables. The package is responsible for invoking the
executables and figuring out what type of installation(s) are in the
prefix, and returning one or more specs (each with version, variants or
whatever else the user decides to include in the spec).

The found specs and prefixes will be added to the user's `packages.yaml`
file. Providing the `--not-buildable` option will mark all generated
entries in `packages.yaml` as `buildable: False`

cray platform: support cray Cluster and XC type machines (#12989)
Cray has two machine types. "XC" machines are the larger
machines more common in HPC, but "Cluster" machines are
also cropping up at some HPC sites. Cluster machines run
a slightly different form of the CrayPE programming environment,
and often come without default modules loaded. Cluster
machines also run different versions of some software, and run
a linux distro on the backend nodes instead of running Compute 
Node Linux (CNL).

Below are the changes made to support "Cluster" machines in
Spack. Some of these changes are semi-related general upkeep
of the cray platform.

* cray platform: detect properly after module purge

* cray platform: support machines running OSs other than CNL

Make Cray backend OS delegate to LinuxDistro when no cle_release file
favor backend over frontend OS when name clashes

* cray platform: target detection uses multiple strategies

This commit improves the robustness of target
detection on Cray by trying multiple strategies.

The first one that produces results wins. If
nothing is found only the generic family of the
frontend host is used as a target.

* cray-libsci: add package from NERSC

* build_env: unload cray-libsci module when not explicitly needed

cray-libsci is a package in Spack. The cray PrgEnv
modules load it implicitly when we set up the compiler.
We now unload it after setting up the compiler and
only reload it when requested via external package.

* util/module_cmd: more robust module parsing

Cray modules have documentation inside the module
that is visible to the `module show` command.
Spack module parsing is now robust to documentation 
inside modules.

* cce compiler: uses clang flags for versions >= 9.0

* build_env: push CRAY_LD_LIBRARY_PATH into everything

Some Cray modules add paths to CRAY_LD_LIBRARY_PATH
instead of LD_LIBRARY_PATH. This has performance benefits
at load time, but leads to Spack builds not finding their
dependencies from external modules.
Spack now prepends CRAY_LD_LIBRARY_PATH to
LD_LIBRARY_PATH before beginning the build.

* mvapich2: setup cray compilers when on cray

previously, mpich was the only mpi implementation to support
cray systems (because it is the MPI on Cray XC systems). 
Cray cluster systems use mvapich2, which now supports cray
compiler wrappers.

* build_env: clean pkgconf from environment

Cray modules silently add pkgconf to the user environment
This can break builds that do not user pkgconf.
Now we remove it frmo the environment and add it again if it
is in the spec. 

* cray platform: cheat modules for rome/zen2 module on naples/zen node

Cray modules for naples/zen architecture currently specify
rome/zen2. For now, we detect this and return zen for modules
named `craype-x86-rome`.

* compiler: compiler default versions

When detecting compiler default versions for target/compiler
compatibility checks, Spack previously ran the compiler without
setting up its environment. Now we setup a temporary environment
to run the compiler with its modules to detect its version.

* compilers/cce: improve logic to determine C/C++ std flags

* tests: fix existing tests to play nicely with new cray support

* tests: test new functionality

Some new functionality can only be tested on a cray system.
Add tests for what can be tested on a linux system.

1cff717ca8 Fix git-related commands not working in worktrees
If spack is checked out in a git worktree (see [1]), all git-related
commands fail because the `spack_is_git_repo()`-check is not thorough
enough.

When developing in a feature-branch in a seperate worktree, this is
annoying as all unittests regarding git-related spack commands fail,
cluttering the test results with false-positives.

Spack command extensions: error-handling (#13635)
Generally speaking, errors that are encountered when attempting to load
command extensions now terminate the running Spack instance.

* Added new exceptions `spack.cmd.PythonNameError` and
  `spack.cmd.CommandNameError`.
* New functions `spack.cmd.require_python_name(pname)` and
  `spack.cmd.require_cmd_name(cname)` check that `pname` and `cname`
  respectively meet requirements, throwing the appropriate error if not.
* `spack.cmd.get_module()` uses `require_cmd_name()` and passes through
  exceptions from module load attempts.
* `spack.cmd.get_command()` uses `require_cmd_name()` and invokes
  `get_module()` with the correct command-name form rather than the
  previous (incorrect) Python name.
* Added New exceptions `spack.extensions.CommandNotFoundError` and
  `spack.extensions.ExtensionNamingError`.
* `_extension_regexp` has a new leading underscore to indicate expected
  privacy.
* `spack.extensions.extension_name()` raises an `ExtensionNamingError`
  rather than using `tty.warn()`.
* `spack.extensions.load_command_extension()` checks command source
  existence early and bails out if missing. Also, exceptions raised by
  `load_module_from_file()` are passed through.
* `spack.extensions.get_module()` raises `CommandNotFoundError` as
  appropriate.
* Spack `main()` allows `parser.add_command()` exceptions to cause
  program end.

Tests:

* More common boilerplate has been pulled out into fixtures including
  `sys.modules` dictionary cleanup and resource-managed creation of a
  simple command extension with specified contents in the source file
  for a single named command.
* "Hello, World!" test now uses a command named `hello-world` instead of
  `hello` in order to verify correct handling of commands with hyphens.
* New tests for:
  * Missing (or misnamed) command.
  * Badly-named extension.
  * Verification that errors encountered during import of a command are
    propagated upward.

mainly to be more consistent with practices used in other

adds or reworks unit tests for these functions and extends 
their docstrings.

tests: each mock package now has its own class (#16157)
Packages in Spack are classes, and we need to be able to execute class
methods on mock packages.  The previous design used instances of a single
MockPackage class; this version gives each package its own class that can
spider depenencies.  This allows us to implement class methods like
`possible_dependencies()` on mock packages.

This design change moves mock package creation into the
`MockPackageMultiRepo`, and mock packages now *must* be created from a
repo.  This is required for us to mock `possible_dependencies()`, which
needs to be able to get dependency packages from the package repo.

Changes include:

* `MockPackage` is now `MockPackageBase`
* `MockPackageBase` instances must now be created with
  `MockPackageMultiRepo.add_package()`
* add `possible_dependencies()` method to `MockPackageBase`
* refactor tests to use new code structure
* move package mocking infrastructure into `spack.util.mock_package`,
  as it's becoming a more sophisticated class and it gets lots in `conftest.py`

spack info: allow variants section to be as wide as the terminal (#16254)
The variants table in `spack info` is cramped, as the *widest* it can be
is 80 columns.  And that's actually only sort of true -- the padding
calculation is off, so it still wraps on terminals of size 80 because it
comes out *slightly* wider.

This change looks at the terminal size and calculates the width of the
description column based on it.  On larger terminals, the output looks
much nicer, and on small terminals, the output no longer wraps.

Here's an example  for `spack info qmcpack` with 110 columns.

compiler wrappers: don't override -isystem with -I (#16077)
If the Spack compiler wrapper encounters any "-isystem" option, then
when adding include directories for Spack dependencies, Spack will
use "-isystem" instead of "-I". This prevents Spack-generated "-I"
options from overriding the "-isystem" options generated by the build
system. To ensure that build-system "-isystem" directories are
searched first, Spack places all of its inserted "-isystem"
directories after.

The new ordering of -isystem includes is:

* -isystem from build system (not system directories)
* -isystem from Spack
* -isystem from build system (for directories like /usr/include)

The prior order of "-I" arguments is preserved (although as of this
commit Spack no longer generates -I if -isystem is detected):

* -I from build system (not system directories)
* -I from Spack (only if there are no "-isystem" options)
* -I from build system (for directories like /usr/include)

autotools: set FORCE_UNSAFE_CONFIGURE to 1 in autotools.py (#16132)
This commit sets the `FORCE_UNSAFE_CONFIGURE` environment variable to 1 in autotools builds.

We see a lot of builds popping up and complaining about `FORCE_UNSAFE_CONFIGURE`.  This behavior is not actually part of `autoconf` per se.  It comes from this patch to `mknod.m4`, which is used by a lot of autoconf builds:

    * https://lists.gnu.org/archive/html/bug-gnulib/2010-07/msg00282.html

Which originated from this problem that someone had on AIX:

    * https://lists.gnu.org/archive/html/bug-gnulib/2010-07/msg00279.html

The gist of the problem seems to be that they want to check whether `mknod` can do something as root, but instead of checking whether they're running as root and using `su` or something to test this, they just made it harder to run `configure` as root.

This seems very ad hoc and this is one of many checks that are run as root in `configure`.  Many of them run before this check, so it's not clear that the `FORCE_UNSAFE_CONFIGURE` thing is even preventing bad things from happening.

So:
1. This only happens in `autotools` builds, so we should go ahead and put it into `autotools.py` instead of in the global build environment, and

2. The variable does too little and provides a false sense of security in the first place, so we'll just disable it and avoid the nuisance.  If we really feel strongly about this we can put some warnings in Spack about running as root, but at the top level, not in the middle of an already running script like `configure`.

SourceForge: Mirror Mixin (#16112)
* SourceForge: Mirror Mixin

Add a mixing class for direct `CNAME`s to sourceforge mirrors.
Since the main gateway servers are often down, this could reduce
timeouts and fetch errors for sourceforge.net hosted software.

* SourceForge: unspectacular mirror replacement

add mirrors to all sourceforge packages with trivial
download logic.

tested fetch of latest version of each of these packages
with various mirrors before committing.

* SourceForge: xz

the author homepage is chronocially overrun and this is the offical
upload with many mirrors.

f6d26db939 macos: use DYLD_FALLBACK_LIBRARY_PATH instead of DYLD_LIBRARY_PATH
`DYLD_LIBRARY_PATH` can frequently break builtin macOS software when
pointed at Spack libraries.  This is because it takes *higher* precedence
than the default library search paths, which are used by system software.

`DYLD_FALLBACK_LIBRARY_PATH`, on the other hand, takes lower precedence.
At first glance, this might seem bad, because the software installed by
Spack in an environment needs to find *its* libraries, and it should not
use the defaults.  However, Spack's isntallations are always `RPATH`'d,
so they do not have this problem.

`DYLD_FALLBACK_LIBRARY_PATH` is thus useful for things built in an
environment that need to use Spack's libraries, that don't set *their*
RPATHs correctly for whatever reason. We now prefer it to
`DYLD_LIBRARY_PATH` in modules and in environments because it helps a
little bit, and it is much less intrusive.

Bugfix: For spack buildcache check, Handle specs where only the hash is (#15663)
provided (#15662).

Prior to this fix, the checked Spec object would not be populated, and
concretization would fail.

277350ceed Make tags case insensitive
Currently, tags are case sensitive, which is unintuitive:
```console
$ spack list -t hpc
==> 2 packages.
nek5000  nektools
$ spack list -t HPC
==> 1 packages.
mfem
$ spack list -t Hpc
==> 0 packages.
```

This change makes them case insensitive:
```console
$ spack list -t hpc
==> 3 packages.
mfem  nek5000  nektools
$ spack list -t HPC
==> 3 packages.
mfem  nek5000  nektools
$ spack list -t Hpc
==> 3 packages.
mfem  nek5000  nektools
```

740f8fe1a9 bugfix: spack test should not output [+] for mock installs (#15609)
`spack test` has a spurious '[+] ' in the output:

```
lib/spack/spack/test/install.py .........[+] ......
```

Output is properly suppressed:

```

430ca7c7cf spack install terminal output handling in foreground/background (#15723)
Makes the following changes:

* (Fixes #15620) tty configuration was failing when stdout was 
  redirected. The implementation now creates a pseudo terminal for
  stdin and checks stdout properly, so redirections of stdin/out/err
  should be handled now.
* Handles terminal configuration when the Spack process moves between
  the foreground and background (possibly multiple times) during a
  build.
* Spack adjusts terminal settings to allow users to to enable/disable
  build process output to the terminal using a "v" toggle, abnormal
  exit cases (like CTRL-C) could leave the terminal in an unusable
  state. This is addressed here with a special-case handler which
  restores terminal settings.

Significantly extend testing of process output logger:

* New PseudoShell object for setting up a master and child process
  and configuring file descriptor inheritance between the two
* Tests for "v" verbosity toggle making use of the added PseudoShell
  object
* Added `uniq` function which takes a list of elements and replaces
  any consecutive sequence of duplicate elements with a single
  instance (e.g. "112211" -> "121")

55f5afaf3c database: maintain in-memory consistency on remove (#15777)
The performance improvements done in #14693 where leaving the DB in an inconsistent state when specs were removed from it. This PR updates the DB internal state whenever the DB is written to a file.

Note that we still cannot properly enumerate installed dependents, so there is a TODO in this code. Fixing that will require the dependents dictionaries in specs to be re-keyed (either by hash, or not keyed at all -- a list would do).  See #11983 for details.

6b559912c1 performance: add a verification file to the database (#14693)
Reading the database repeatedly can be quite slow.  We need a way to speed
up Spack when it reads the DB multiple times, but the DB has not been
modified between reads (which is nearly all the time).

- [x] Add a file containing a unique uuid that is regenerated at database
    write time. Use this uuid to suppress re-parsing the database
    contents if we know a previous uuid and the uuid has not changed.

- [x] Fix mutable_database fixture so that it resets the last seen
    verifier when it resets.

- [x] Enable not rereading the database immediately after a write. Make
    the tests reset the last seen verifier in between tests that use the
    database fixture.

- [x] make presence of uuid module optional

9b5805a5cd Remove DB conversion of old index.yaml (#15298)
Removed the code that was converting the old index.yaml format into
index.json. Since the change happened in #2189 it should be
considered safe to drop this (untested) code.

ed2781973c Source devnull in environment_after_sourcing_files (closes #15775) (#15791)
spack.util.environment_after_sourcing_files compares the local
environment against a shell environment after having sourced a
file; but this ends up including the default shell profile and
rc, which might differ from the local environment.

To change this, compare against the default shell environment,
expressed here as 'source /dev/null'.
