* Bugfix: spack.yaml concretizer:unify needs to be read and used
* Optional: add environment test to ensure configuration scheme is used
* Activate environment in unit tests
A more proper solution would be to keep
an environment instance configuration as
an attribute, but that is a bigger refactor
* Delay evaluation of Environment.unify
* Slightly simplify unit tests

Allow the following formats:
```yaml
mirrors:
name: <url>
```
```yaml
mirrors:
name:
url: s3://xyz
access_pair: [x, y]
```
```yaml
mirrors:
name:
fetch: http://xyz
push:
url: s3://xyz
access_pair: [x, y]
```
And reserve two new properties to indicate the mirror type (e.g.
mirror.spack.io is a source mirror, not a binary cache)
```yaml
mirrors:
spack-public:
source: true
binary: false
url: https://mirror.spack.io
```
A few packages have version directives evaluated
within if statements, conditional on the value of
`platform.platform()`.
Sometimes there are no cases for e.g. platform=darwin and that
causes a lot of spurious failures with version existence
audits.
This PR allows expressing conditions to skip version
existence checks in audits and avoid these spurious reports.
### Rationale
While working on #29549, I noticed a lot of inconsistencies in our argparse help messages. This is important for fish where these help messages end up as descriptions in the tab completion menu. See https://github.com/spack/spack/pull/29549#issuecomment-1627596477 for some examples of longer or more stylized help messages.
### Implementation
This PR makes the following changes:
- [x] help messages start with a lowercase letter.
- [x] Help messages do not end with a period
- [x] the first line of a help message is short and simple
longer text is separated by an empty line
- [x] "help messages do not use triple quotes"
"""(except docstrings)"""
- [x] Parentheses not needed for string concatenation inside function call
- [x] Remove "..." "..." string concatenation leftover from black reformatting
- [x] Remove Sphinx argument docs from help messages
The first 2 choices aren't very controversial, and are designed to match the syntax of the `--help` flag automatically added by argparse. The 3rd choice is more up for debate, and is designed to match our package/module docstrings. The 4th choice is designed to avoid excessive newline characters and indentation. We may actually want to go even further and disallow docstrings altogether.
### Alternatives
Choice 3 in particular has a lot of alternatives. My goal is solely to ensure that fish tab completion looks reasonable. Alternatives include:
1. Get rid of long help messages, only allow short simple messages
2. Move longer help messages to epilog
3. Separate by 2 newline characters instead of 1
4. Separate by period instead of newline. First sentence goes into tab completion description
The number of commands with long help text is actually rather small, and is mostly relegated to `spack ci` and `spack buildcache`. So 1 isn't actually as ridiculous as it sounds.
Let me know if there are any other standardizations or alternatives you would like to suggest.
Refactor `TermTitle` into `InstallStatus` and use it to show progress
information both in the terminal title as well as inline. This also
turns on the terminal title status by default.
The inline output will look like the following after this change:
```
==> Installing m4-1.4.19-w2fxrpuz64zdq63woprqfxxzc3tzu7p3 [4/4]
```
People frequently ask us how to pipe `spack find` output to other commands, and we tell
them to do things like this:
```console
$ spack find --format "/{hash}" | spack uninstall -ay
```
Sometimes users don't know about hash references and come up with potentially ambiguous
formulations like this:
```console
spack find --format {name}@{version}%{compiler} | spack uninstall -ay
```
Since this is a common enough thing to want to do, and to make it more obvious how, this
PR adds a `-H` / `--hashes` as a shortcut, so you can now just do:
```console
spack find -H | spack uninstall -ay
```
`"%s" % spec` formats the spec with deps included, which produces sometimes KBs
of data and is slow to run in pure Python. It can delay otherwise very short-lived
read/write locks on the database.
Discovered in #38762 where profile output showed about 2 seconds is spent in
`spec.format`, which is significant overhead when using multiprocessing to install
from binary cache in parallel (installation often takes <5s for small packages). With
this change, `spec.format` no longer shows up in profile output.
(This line hasn't changed since Spack v0.9 ;p)
* move format() call to custom NoSuchSpecError exception
* add a comment saying why, so we can eventually change `Spec.__str__`
1. Fix O(n^2) iteration in `_get_overwrite_specs`
2. Early exit `get_by_hash` on full hash
3. Fix O(n^2) double lookup in `all_matching_specs` with hashes
4. Fix some legibility issues
* When installing a package Spack will attempt to set group permissions on
the install prefix even when the configuration does not specify a group.

Move the logic checking which mirrors have the specs we need closer
to where that information is needed. Also update the staging summary
to contain a brief description of why we scheduled or pruned each
job. If a spec was found on any mirrors, regardless of whether
we scheduled a job for it, print those mirrors.
PowerShell requires explicit shell and env support in Spack.
This is due to the distinct differences in shell interactions between
cmd and pwsh. Add a doskey in pwsh piping 'spack' commands to a
powershell script similar to the sh function 'spack'. Add
support for PowerShell-specific shell interactions from Spack
(set/unset shell variables).
* Support hardlinks/junctions on Windows systems without developer
mode enabled
* Generally, use of llnl.util.symlink.symlink is preferred over
os.symlink since it handles this automatically
* Generally an error is now reported if a user attempts to create a
symlink to a file that does not exist (this was previously allowed
on Linux/Mac).
* One exception to this: when Spack installs files from the source
into their final prefix, dangling symlinks are allowed (on
Linux/Mac - Windows does not allow this in any circumstance).
The intent behind this is to avoid generating failures for
installations on Linux/Mac that were succeeding before.
* Because Windows is strict about forbidding dangling symlinks,
`traverse_tree` has been updated to skip creating symlinks if they
would point to a file that is ignored. This check is not
transitive (i.e., a symlink to a symlink to an ignored file would
not be caught appropriately)
* Relocate function: resolve_link_target_relative_to_the_link
(this is not otherwise modified)

Update list of excluded variables in `from_sourcing_file` function to
cover all variables specific to Environment Modules or Lmod. Add
specifically variables relative to the definition of `module()`, `ml()`
and `_module_raw()` Bash functions.
Fixes#13504
Update `env.set` command and underlying `SetEnv` object to add the `raw`
boolean attribute. `raw` is optional and set to False by default. When
set to True, value format is skipped for object when generating
environment modifications.
With this change it is now possible to define environment variable
whose value contains variable reference syntax (like `{foo}` or `{}`)
that should be set as-is.
Fixes#29578
Spack flags supplied by users should supersede flags from package build systems and
other places in Spack. However, Spack currently adds user-supplied flags to the
beginning of the compile line, which means that in some cases build system flags will
supersede user-supplied ones.
The right place to add a flag to ensure it has highest precedence for the compiler really
depends on the type of flag. For example, search paths like `-L` and `-I` are examined
in order, so adding them first is highest precedence. Compilers take the *last* occurrence
of optimization flags like `-O2`, so those should be placed *after* other such flags. Shim
libraries with `-l` should go *before* other libraries on the command line, so we want
user-supplied libs to go first, etc.
`lib/spack/env/cc` already knows how to split arguments into categories like `libs_list`,
`rpath_dirs_list`, etc., so we can leverage that functionality to merge user flags into
the arg list correctly.
The general rules for injected flags are:
1. All `-L`, `-I`, `-isystem`, `-l`, and `*-rpath` flags from `spack_flags_*` to appear
before their regular counterparts.
2. All other flags ordered with the ones from flags after their regular counterparts,
i.e. `other_flags` before `spack_flags_other_flags`
- [x] Generalize argument categorization into its own function in the `cc` shell script
- [x] Apply the same splitting logic to injected flags and flags from the original compile line.
- [x] Use the resulting flag lists to merge user- and build-system-supplied flags by category.
- [x] Add tests.

The `unparser` that Spack uses for package hashing had several tweaks to ensure compatibility
with Python 2.7:
1. Currently, the unparser automatically moves `*` and `**` args to the end to preserve
compatibility with `python@:3.4`
2. `print a, b, c` statements and single-tuple `print((a, b, c))` function calls were
remapped to `print(a, b, c)` in the unparsed output for consistency across versions.
(1) is causing issues in our tests because a recent patch to the Python source code
(https://github.com/python/cpython/pull/102953/files#diff-7972dffec6674d5f09410c71766ac6caacb95b9bccbf032061806ae304519c9bR813-R823)
has a `**` arg before an named argument, and we round-trip the core python source code
as a test of our unparser. This isn't actually a break with our consistent unpausing -- it's still
consistent, the python source just doesn't unparse to the same thing anymore. It does makes
it harder to test, so it's not worth maintaining the Python2-specific stuff anymore.
Since we only support `python@3.6:`, this PR removes (1) and (2) from the unparser, but keeps
one last tweak for unicode AST inconsistencies, as it's still needed for Python 3.5-3.7.
This fixes the CI error we've been seeing on `python@3.11.4` and `python@3.10.12`. Again, that
bug exists only in the test system and doesn't affect our canonical hashing of Python code.
* DependencySpec: add virtuals attribute on edges
This works for both the new and the old concretizer. Also,
added type hints to involved functions.
* Improve virtual reconstruction from old format
* Reconstruct virtuals when reading from Cray manifest
* Reconstruct virtual information on test dependencies
Update Tcl modulefile template to use the `depends-on` command to
autoload modules if Lmod is the current module tool.
Autoloading modules with `module load` command in Tcl modulefile does
not work well for Lmod at some extend. An attempt to unload then load
designated module is performed each time such command is encountered. It
may lead to a load storm that may not end correctly with large number of
module dependencies.
`depends-on` command should be used for Lmod instead of `module load`,
as it checks if module is already loaded, and does not attempt to reload
this module.
Lua modulefile template already uses `depends_on` command to autoload
dependencies. Thus it is already considered that to use Lmod with Spack,
it must support `depends_on` command (version 7.6+).
Environment Modules copes well with `module load` command to autoload
dependencies (version 3.2+). `depends-on` command is supported starting
version 5.1 (as an alias of `prereq-all` command) which was relased last
year.
This change introduces a test to determine if current module tool that
evaluates modulefile is Lmod. If so, autoload dependencies are defined
with `depends-on` command. Otherwise `module load` command is used.
Test is based on `LMOD_VERSION_MAJOR` environment variable, which is set
by Lmod starting version 5.1.
Fixes#36764
