At least with ZSH, prefix inspections containing `./bin` result in a
`$PREFIX/./bin` and result in strange `$PATH` handling.
I.e., `module load git` will prepend `/path/to/git/./bin`, `which git`
will find the right executable, but `git --version` will print the
system one. Normalize the relative path to avoid this behavior.

The code in FileCache for write_transaction attempts to delete the temporary file when an exception occurs under the context by calling shutil.rmtree. However, rmtree only operates on directories while the rest of FileCache uses normal files. This causes an empty file to be written to the cache key when unneeded.
Use os.remove instead which operates on normal files.

fixes#34518
Fix an issue due to the MRO chain of the package wrapper
during build. Before this PR we were always returning
False when the builder object was created before the
run_tests method was monkey patched.
* Add a regression test for 33928
* PackageBase should not set `(build|install)_time_test_callbacks`
* Fix audits by preserving the current semantic

Avoid text decoding and encoding when combining log files, instead
combine in binary mode.
Also do a buffered copy which is sometimes faster for large log files.
* uninstall: fix accidental cubic complexity
Currently spack uninstall runs in worst case cubic time complexity
thanks to traversal during traversal during traversal while collecting
the specs to be uninstalled.
Also brings down the number of error messages printed to something
linear in the amount of matching specs instead of quadratic.
Revamp the timer so we always have a designated begin and end.
Fix a bug where the phase timer was stopped before the phase started,
resulting in incorrect timing reports in timers.json.
Environments and environment views have taken over the role of `spack activate/deactivate`, and we should deprecate these commands for several reasons:
- Global activation is a really poor idea:
- Install prefixes should be immutable; since they can have multiple, unrelated dependents; see below
- Added complexity elsewhere: verification of installations, tarballs for build caches, creation of environment views of packages with unrelated extensions "globally activated"... by removing the feature, it gets easier for people to contribute, and we'd end up with fewer bugs due to edge cases.
- Environment accomplish the same thing for non-global "activation" i.e. `spack view`, but better.
Also we write in the docs:
```
However, Spack global activations have two potential drawbacks:
#. Activated packages that involve compiled C extensions may still
need their dependencies to be loaded manually. For example,
``spack load openblas`` might be required to make ``py-numpy``
work.
#. Global activations "break" a core feature of Spack, which is that
multiple versions of a package can co-exist side-by-side. For example,
suppose you wish to run a Python package in two different
environments but the same basic Python --- one with
``py-numpy@1.7`` and one with ``py-numpy@1.8``. Spack extensions
will not support this potential debugging use case.
```
Now that environments are established and views can take over the role of activation
non-destructively, we can remove global activation/deactivation.
Currently, external `PythonPackage`s cause install failures because the logic in `PythonPackage` assumes that it can ask for `spec["python"]`. Because we chop off externals' dependencies, an external Python extension may not have a `python` dependency.
This PR resolves the issue by guaranteeing that a `python` node is present in one of two ways:
1. If there is already a `python` node in the DAG, we wire the external up to it.
2. If there is no existing `python` node, we wire up a synthetic external `python` node, and we assume that it has the same prefix as the external.
The assumption in (2) isn't always valid, but it's better than leaving the user with a non-working `PythonPackage`.
The logic here is specific to `python`, but other types of extensions could take advantage of it. Packages need only define `update_external_dependencies(self)`, and this method will be called on externals after concretization. This likely needs to be fleshed out in the future so that any added nodes are included in concretization, but for now we only bolt on dependencies post-concretization.

Spack currently creates a temporary sbang that is moved "atomically" in place,
but this temporary causes races when multiple processes start installing sbang.
Let's just stick to an idempotent approach. Notice that we only re-install sbang
if Spack updates it (since we do file compare), and sbang was only touched
18 times in the past 6 years, whereas we hit the sbang tempfile issue
frequently with parallel install on a fresh spack instance in CI.
Also fixes a bug where permissions weren't updated if config changed but
the latest version of the sbang file was already installed.
The `intel` compiler at versions > 20 is provided by the `intel-oneapi-compilers-classic`
package (a thin wrapper around the `intel-oneapi-compilers` package), and the `oneapi`
compiler is provided by the `intel-oneapi-compilers` package.
Prior to this work, neither of these compilers could be bootstrapped by Spack as part of
an install with `install_missing_compilers: True`.
Changes made to make these two packages bootstrappable:
1. The `intel-oneapi-compilers-classic` package includes a bin directory and symlinks
to the compiler executables, not just logical pointers in Spack.
2. Spack can look for bootstrapped compilers in directories other than `$prefix/bin`,
defined on a per-package basis
3. `intel-oneapi-compilers` specifies a non-default search directory for the
compiler executables.
4. The `spack.compilers` module now can make more advanced associations between
packages and compilers, not just simple name translations
5. Spack support for lmod hierarchies accounts for differences between package
names and the associated compiler names for `intel-oneapi-compilers/oneapi`,
`intel-oneapi-compilers-classic/intel@20:`, `llvm+clang/clang`, and
`llvm-amdgpu/rocmcc`.
- [x] full end-to-end testing
- [x] add unit tests
"spack install foo" no longer adds package "foo" to the environment
(i.e. to the list of root specs) by default: you must specify "--add".
Likewise "spack uninstall foo" no longer removes package "foo" from
the environment: you must specify --remove. Generally this means
that install/uninstall commands will no longer modify the users list
of root specs (which many users found problematic: they had to
deactivate an environment if they wanted to uninstall a spec without
changing their spack.yaml description).
In more detail: if you have environments e1 and e2, and specs [P, Q, R]
such that P depends on R, Q depends on R, [P, R] are in e1, and [Q, R]
are in e2:
* `spack uninstall --dependents --remove r` in e1: removes R from e1
(but does not uninstall it) and uninstalls (and removes) P
* `spack uninstall -f --dependents r` in e1: will uninstall P, Q, and
R (i.e. e2 will have dependent specs uninstalled as a side effect)
* `spack uninstall -f --dependents --remove r` in e1: this uninstalls
P, Q, and R, and removes [P, R] from e1
* `spack uninstall -f --remove r` in e1: uninstalls R (so it is
"missing" in both environments) and removes R from e1 (note that e1
would still install R as a dependency of P, but it would no longer
be listed as a root spec)
* `spack uninstall --dependents r` in e1: will fail because e2 needs R
Individual unit tests were created for each of these scenarios.
