A LazyReference object is a reference to an attribute of a
lazily evaluated singleton. Its only purpose is to let developers
use shorter names to refer to such attribute.
This class does more harm than good, as it obfuscates the fact
that we are using the attribute of a global object. Also, it can easily
go out of sync with the singleton it refers to if, for instance, the
singleton is updated but the references are not.
This commit removes the LazyReference class entirely, and access
the attributes explicitly passing through the global value to which
they are attached.
These tests now work without any changes to core. Furthermore, it is
surprising that they had to be disabled (at least, as long as the
installer.py tests are run on Windows: these tests are more-basic
and their functionality would have been exercised automatically).
Without --allow-root spack cannot push binaries that contain paths in
binaries. This flag is almost always needed, so there is no point of
requiring users to spell it out.
Even without --allow-root, rpaths would still have to be patched, so the
flag is not there to guarantee binaries are not modified on install.
This commit makes --allow-root the default, and drops the code
required for it. It also deprecates `spack buildcache preview`, since
the command made sense only with --allow-root.
As a side effect, Spack no longer depends on binutils for relocation
Add support for conflict directives in Lua modulefile like done for Tcl
modulefile.
Note that conflicts are correctly honored on Lmod and Environment
Modules <4.2 only if mutually expressed on both modulefiles that
conflict with each other.
Migrate conflict code from Tcl-specific classes to the common part. Add
tests for Lmod and split the conflict test case in two.

* When using system tools to unpack a .gz file, the input file needs a
different name than the output file. Normally, we generate this new
name by stripping off the .gz extension off of the file name.
This was not sufficient if the file name did not have an extension,
so we temporarily rename the file in that case.
* When using system tar utility to untar on Windows, we were (erroneously)
skipping the actual untar step if the filename was lacking a .tar
extension
* For foo.txz, we were not changing the extension of the decompressed file
(i.e. we would decompress foo.txz to foo.txz). This did not cause any
problems, but is confusing, so has been updated such that the output
filename reflects its decompressed state (i.e. foo.tar).
* Added test for strip_compression_extension
* Update test_native_unpacking to test each archive type with and without
an extension as part of the file name (i.e. we test "foo.tar.gz", but
also make sure we decompress properly if it is named "foo").
Running `spack test run <python package>` resulted in the error
```
'str' object is not callable
```
because the python executable was not set correctly.
Lock objects can now be instantiated independently,
without being tied to the global configuration. The
same is true for database and store objects.
The database __init__ method has been simplified to
take a single lock configuration object. Some common
lock configurations (e.g. NO_LOCK or NO_TIMEOUT) have
been named and are provided as globals.
The use_store context manager keeps the configuration
consistent by pushing and popping an internal scope.
It can also be tuned by passing extra data to set up
e.g. upstreams or anything else that might be related
to the store.
* 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.
