As detailed in https://bugs.python.org/issue33725, starting new
processes with 'fork' on Mac OS is not guaranteed to work in general.
As of Python 3.8 the default process spawning mechanism was changed
to avoid this issue.
Spack depends on the fork-based method to preserve file descriptors
transparently, to preserve global state, and to avoid pickling some
objects. An effort is underway to remove dependence on fork-based
process spawning (see #18205). In the meantime, this allows Spack to
run with Python 3.8 on Mac OS by explicitly choosing to use 'fork'.

I know that it's just an example, but I was trying to figure out what was going on and it wasn't making sense....
`tput sgr0` resets the terminal state (http://linuxcommand.org/lc3_adv_tput.php) and I can't see any reason to do it twice. Deleting the second occurrence doesn't seem to break the fancy prompt effect.
Compilers can have strange versions, as the version is provided by the user. We know the real version internally, (by querying the compiler) so expose it as a property and use it in places we don't trust the user. Eventually we'll refactor this with compilers as dependencies, but this is the best fix we've got for now.
- [x] Make `real_version` a property and cache the version returned by the compiler
- [x] Use `real_version` to make C++ language level flags work
Restores the fetching progress bar sans failure outputs; restores non-debug reporting of using fetch cache for installed packages; and adds a unit test.
* Add status bar check to test and fetch output when already installed
Some of the feature flags are named differently and clwb is missing on
my i7-1065G7. cascadelake and cannonlake might have similar problems but
I do not have access to those architectures to test.
* make_package_relative: relocate rpaths on cray
* relocate_package: relocate rpaths on cray
* platforms: add `binary_formats` property
We need to know which binary formats are supported on a platform so we
know which types of relocations to try. This adds a list of binary
formats to the platform and removes a bunch of special cases from
`binary_distribution.py`.

Before this PR, packages.yaml files that contained an
empty "paths" or "modules" attribute were not updated
correctly, since the update function was not reporting
them as changed after the update.
This PR fixes that issue and adds a unit test to
avoid regression.
This commit adds output to the "spack external find"
command to inform users of the result of the operation.
It also fixes a bug introduced in #17804 due to the fact
that a function was not updated to conform to the new
packages.yaml format (_get_predefined_externals).
* Handle uninstalled rootspecs in buildcache
- Do not parse specs / find matching specs when in an environment and no
package string is provided
- Error only when a spec.yaml or spec string are not installed. In an
environment it is fine when the root spec does not exist.
- When iterating through the matched specs, simply skip uninstalled
packages
* Run Python2.6 unit tests on Github Actions
* Skip url tests on Python 2.6 to reduce waiting times
* Skip foreground background tests on Python 2.6 to reduce waiting times
* Removed references to Travis in the documentation
* Deleted install_patchelf.sh (can be installed from repo on CentOS 6)
* Buildcache:
* Try mocking an install of quux, corge and garply using prebuilt binaries
* Put patchelf install after ccache restore
* Add script to install patchelf from source so it can be used on Ubuntu:Trusty which does not have a patchelf pat package. The script will skip building on macOS
* Remove mirror at end of bindist test
* Add patchelf to Ubuntu build env
* Revert mock patchelf package to allow other tests to run.
* Remove depends_on('patchelf', type='build') relying instead on
* Test fixture to ensure patchelf is available.
* Call g++ command to build libraries directly during test build
* Flake8
* Install patchelf in before_install stage using apt unless on Trusty where a build is done.
* Add some symbolic links between packages
* Flake8
* Flake8:
* Update mock packages to write their own source files
* Create the stage because spec search does not create it any longer
* updates after change of list command arguments
* cleanup after merge
* flake8
- [x] Remove references to `master` branch
- [x] Document how release branches are structured
- [x] Document how to make a major release
- [x] Document how to make a point release
- [x] Document how to do work in our release projects
* Move flake8 tests on Github Actions
* Move shell test to Github Actions
* Moved documentation build to Github Action
* Don't run coverage on Python 2.6
Since we get connection errors consistently on Travis
when trying to upload coverage results for Python 2.6,
avoid computing coverage entirely to speed-up tests.
`spack -V` stopped working when we added the `releases/latest` tag to
track the most recent release. It started just reporting the version,
even on a `develop` checkout. We need to tell it to *only* search for
tags that start with `v`, so that it will ignore `releases/latest`.
`spack -V` also would print out unwanted git eror output on a shallow
clone.
- [x] add `--match 'v*'` to `git describe` arguments
- [x] route error output to `os.devnull`
`spack buildcache list` was trying to construct an `Arch` object and
compare it to `arch_for_spec(<spec>)`. for each spec in the buildcache.
`Arch` objects are only intended to be constructed for the machine they
describe. The `ArchSpec` object (part of the `Spec`) is the descriptor
that lets us talk about architectures anywhere.
- [x] Modify `spack buildcache list` and `spack buildcache install` to
filter with `Spec` matching instead of using `Arch`.
- [x] Make it easier to get a `Spec` with a proper `ArchSpec` from an
`Arch` object via new `Arch.to_spec()` method.
- [x] Pull `spack.architecture.default_arch()` out of
`spack.architecture.sys_type()` so we can get an `Arch` instead of
a string.
* Loosen Axom's variants, add shared variant for axom, fix clang/xlf rpath'ing problem on blueos
* Fix flake8
* Add main branch to list of known git branches
The modifications in 193e8333fa
introduced a bug in the loading of compiler modules, since a
function that was expecting a list of string was just getting
a string.
This commit fixes the bug and adds an assertion to verify the
prerequisite of the function.
Packages can implement “detect_version” to support detection
of external instances of a package. This is generally easier
than implementing “determine_spec_details”. The API for
determine_version is similar: for example you can return
“None” to indicate that an executable is not an instance
of a package.
Users may implement a “determine_variants” method for a package.
When doing external detection, executables are grouped by version
and each group results in a single invocation of “determine_variants”
for the associated spec. The method returns a string specifying
the variants for the package. The method may additionally return
a dictionary representing extra attributes for the package.
These will be stored in the spec yaml and can be retrieved
from self.spec.extra_attributes
The Spack GCC package has been updated with an implementation
of “determine_variants” which adds the following extra
attributes to the package: c, cxx, fortran
The YAML config for paths and modules of external packages has
changed: the new format allows a single spec to load multiple
modules. Spack will automatically convert from the old format
when reading the configs (the updates do not add new essential
properties, so this change in Spack is backwards-compatible).
With this update, Spack cannot modify existing configs/environments
without updating them (e.g. “spack config add” will fail if the
configuration is in a format that predates this PR). The user is
prompted to do this explicitly and commands are provided. All
config scopes can be updated at once. Each environment must be
updated one at a time.

Relative paths in views have been broken since #17608 or earlier.

A bug was introduced in #13100 where ChildErrors would be redundantly
printed when raised during a build. We should eventually revisit error
handling in builds and figure out what the right separation of
responsibilities is for distributed builds, but for now just skip
printing.
- [x] SpackErrors were designed to be printed by the forked process, not
by the parent, so check if they've already been printed.
- [x] update tests

Fixes#17299
Cray Shasta systems appear to use an unmodified Sles or other Linux operating system on the backend (like Cray "Cluster" systems and unlike Cray "XC40" systems that use CNL).
This updates the CNL version detection to properly note that this is the underlying OS instead of CNL and delegate to LinuxDistro.
* environment-views: fix bug where missing recipe/repo breaks env commands
When a recipe or a repo has been removed from Spack and an environment
is active, it causes the view activation to crash Spack before any
commands can be executed. Further, the error message it not at all clear
in explaining the issue.
This forces view regeneration to always start from scratch to avoid the
missing package recipes, and defaults add_view=False in main for views activated
by the `spack -e` option.
* add messages to env status and deactivate
Warn users that a view may be corrupt when deactivating an environment
or checking its status while active. Updated message for activate.
* tests for view checking

* switch from bool to int debug levels
* Added debug options and changed lock logging to use more detailed values
* Limit installer and timestamp PIDs to standard debug output
* Reduced verbosity of fetch/stage/install output, changing most to debug level 1
* Combine lock log methods; change build process install to debug
* Changed binary cache install messages to extraction messages
* bugfix: make compiler preferences slightly saner
This fixes two issues with the way we currently select compilers.
If multiple compilers have the same "id" (os/arch/compiler/version), we
currently prefer them by picking this one with the most supported
languages. This can have some surprising effects:
* If you have no `gfortran` but you have `gfortran-8`, you can detect
`clang` that has no configured C compiler -- just `f77` and `f90`. This
happens frequently on macOS with homebrew. The bug is due to some
kludginess about the way we detect mixed `clang`/`gfortran`.
* We can prefer suffixed versions of compilers to non-suffixed versions,
which means we may select `clang-gpu` over `clang` at LLNL. But,
`clang-gpu` is not actually clang, and it can break builds. We should
prefer `clang` if it's available.
- [x] prefer compilers that have C compilers and prefer no name variation
to variation.
* tests: add test for which()
Apple's gcc is really clang. We previously ignored it by default but
there was a regression in #17110.
Originally we checked for all clang versions with this, but I know of
none other than `gcc` on macos that actually do this, so limiting to
`apple-clang` should be ok.
- [x] Fix check for `apple-clang` in `gcc.py` to use version detection
from `spack.compilers.apple_clang`
The `spack-build-env.txt` file may contains many secrets, but the obvious one is the private signing key in `SPACK_SIGNING_KEY`. This file is nonetheless uploaded as a build artifact to gitlab. For anyone running CI on a public version of Gitlab this is a major security problem. Even for private Gitlab instances it can be very problematic.

Spack did not support usage of the `--config-scope` option in
combination with an environment: In `lib/spack/spack/main.py`,
`spack.config.command_line_scopes` is set equal to any config scopes
passed by the `--config-scope` option. However, this is done after
activating an environment. In the process of activating an environment,
the `spack.config.config` singleton is instantiated, so later setting of
`spack.config.command_line_scopes` is ignored.
This commit sets command line scopes before activating an environment to
ensure that they are included in the configuration.

For normal users, `-o` or `--no-same-owner` (GNU extension) is
the default behavior, but for the root user, `tar` attempts to preserve
the ownership from the tarball.
This makes `tar` use `-o` all the time. This should improve untarring
files owned by users not available in rootless Docker builds.
