`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.
* 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)

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.

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.

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.
The error message was not updated when the behavior of Spack environments
was changed to not automatically activate the local environment in #17258.
The previous error message no longer makes sense.
When Spack installs a package, it stores repository package.py files
for it and all of its dependencies - any package with a Spack metadata
directory in its installation prefix.
It turns out this was too broad: this ends up including external
packages installed by Spack (e.g. installed by another Spack instance).
Currently Spack doesn't store the namespace properly for such packages,
so even though the package file could be fetched from the external,
Spack is unable to locate it.
This commit avoids the issue by skipping any attempt to locate and copy
from the package repository of externals, regardless of whether they
have a Spack repo directory.
Spack was attempting to calculate abspath on the located config.guess
path even when it was not found (None); this commit skips the abspath
calculation when config.guess is not found.

This prevents the class attribute to be inherited and

maintainers of every Cuda package.
We got rid of `master` after #17377, but users still want a way to get

Fixes#16478
This allows an uninstall to proceed even when encountering pre-uninstall
hook failures if the user chooses the --force option for the uninstall.
This also prevents post-uninstall hook failures from raising an exception,
which would terminate a sequence of uninstalls. This isn't likely essential
for #16478, but I think overall it will improve the user experience: if
the post-uninstall hook fails, there isn't much point in terminating a
sequence of spec uninstalls because at the point where the post-uninstall
hook is run, the spec has already been removed from the database (so it
will never have another chance to run).
Notes:
* When doing spack uninstall -a, certain pre/post-uninstall hooks aren't
important to run, but this isn't easy to track with the current model.
For example: if you are uninstalling a package and its extension, you
do not have to do the activation check for the extension.
* This doesn't handle the uninstallation of specs that are not in the DB,
so it may leave "dangling" specs in the installation prefix

* Some minor fixes to set_permissions() in file_permissions.py
The set_permissions() routine claims to prevent users from creating
world writable suid binaries. However, it seems to only be checking
for/preventing group writable suid binaries.
This patch modifies the routine to check for both world and group
writable suid binaries, and complain appropriately.
* permissions.py: Add test to check blocks world writable SUID files
The original test_chmod_rejects_group_writable_suid tested
that the set_permissions() function in
lib/spack/spack/util/file_permissions.py
would raise an exception if changed permission on a file with
both SUID and SGID plus sticky bits is chmod-ed to g+rwx and o+rwx.
I have modified so that more narrowly tests a file with SUID
(and no SGID or sticky bit) set is chmod-ed to g+w.
I have added a second test test_chmod_rejects_world_writable_suid
that checks that exception is raised if an SUID file is chmod-ed
to o+w
* file_permissions.py: Raise exception when try to make sgid file world writable
Updated set_permissions() in file_permissions.py to also raise
an exception if try to make an SGID file world writable. And
added corresponding unit test as well.
* Remove debugging prints from permissions.py
* Module index should not be unconditionally overwritten
Uncovered after we switched our CI to generate modules for packages
one-by-one rather than in bulk. This overwrote a complete module index
with an index with a single entry, and broke our downstream Spack
instances that needed the upstream module index.
* Changed the 'include' config section to use 'substitute_path_variables' to allow for Spack config variables to be used (e.g. $spack).

Builds can be stopped before the final install phase due to user requests. Those builds
should not be registered as installed in the database.
We had code intended to handle this but:
1. It caught the wrong type of exception
2. We were catching these exceptions to suppress them at a lower level in the stack
This PR allows the StopIteration to propagate through a ChildError, and catches it
properly. Also added to an existing test to prevent regression.
This fixes a fork bomb in `spack versions`. Recursive generation of pools
to scrape URLs in `_spider` was creating large numbers of processes.
Instead of recursively creating process pools, we now use a single
`ThreadPool` with a concurrency limit.
More on the issue: having ~10 users running at the same time spack
versions on front-end nodes caused kernel lockup due to the high number
of sockets opened (sys-admin reports ~210k distributed over 3 nodes).
Users were internal, so they had ulimit -n set to ~70k.
The forking behavior could be observed by just running:
$ spack versions boost
and checking the number of processes spawned. Number of processes
per se was not the issue, but each one of them opens a socket
which can stress `iptables`.
In the original issue the kernel watchdog was reporting:
Message from syslogd@login03 at May 19 12:01:30 ...
kernel:Watchdog CPU:110 Hard LOCKUP
Message from syslogd@login03 at May 19 12:01:31 ...

* add an --exclude-file option to 'spack mirror create' which allows a user to specify a file of specs to exclude when creating a mirror. this is anticipated to be useful especially when using the '--all' option
* allow specifying number of versions when mirroring all packages
* when mirroring all specs within an environment, include dependencies of root specs
* add '--exclude-specs' option to allow user to specify that specs should be excluded on the command line
* add test for excluding specs
fixes#12527
Mention that specs can be uninstalled by hash also in
the help message. Reference `spack gc` in case people
are looking for ways to clean the store from build time
dependencies.
Use "spec" instead of "package" to avoid ambiguity in
the error message.
* Unify tests for compiler command in the same file
Tests for the "spack compiler" command were previously
scattered among different files.
* Tests should use mutable_config, since they modify the compiler list
Because of the way abstract variants are implemented, the following
spec matrix does not work as intended:
```
matrix:
- [foo]
- [bar=a, bar=b]
exclude:
- bar=a
```
because abstract variants always satisfy any variant of the same
name, regardless of values.
This PR converts abstract variants to whatever their appropriate
type is before running satisfaction checks for the excludes clause
in a matrix.
fixes#16841
Now that the version number of GCC reached double digits, an update
to the regex is needed to recognize gcc-10 as an executable to be
inspected when searching for compilers.

Problem: when calling `static_to_shared_library` on the `cray` arch, it
produces a non-sensical compiler command with no input files. For
example, when installing lua@5.2.4, it produced:
'gcc -lm -ldl -o /big-long-spack-path/liblua.so.5.2.4'
Solution: do the same thing on `cray` that is done for `linux`
* account for schema validation errors where the associated instance doesn't have a line number
* fix unrelated flake error (but it must be fixed because this PR touches this file and the flake rules have been updated since the last edit to this file)
Allows `all` to be configured non-buildable in packages.yaml.
The following config would only allow zlib to be built by Spack, all other packages would have to be found as externals.
```
packages:
all:
buildable: False
zlib:
buildable: True
```
This change also adds a code path through the spack ci pipelines
infrastructure which supports PR testing on the Spack repository.
Gitlab pipelines run as a result of a PR (either creation or pushing
to a PR branch) will only verify that the packages in the environment
build without error. When the PR branch is merged to develop,
another pipeline will run which results in the generated binaries
getting pushed to the binary mirror.
Providing only $padding or ${padding} results in an attempt to
substitute a padding of maximum system path length, while leaving
room for the parts of the install path spack generates. Providing
$padding-<len> or ${padding-<len>} simply substitutes padding of
the specified length.
Packages built with lmod core_compiler are placed in `Core`.
Other packages may belong in `Core`. For example, python may be built with a proprietary compiler for performance, but belong on the `Core` directory.
With this PR, lmod config can include a `core_specs` list. Any package that satisfies a spec in that list is placed in `Core`, regardless of its compiler or dependencies.
This improves the documentation for `spack external find` in several ways:
* Provide a code example of implementing `determine_spec_details` for a package
* Explain how to define executables to look for (and also e.g. that they are treated as regular expressions and so can pull in unexpected files).
* Add the "why" for a couple of constraints (i.e. explain that this logic only works for build/run deps because it examines `PATH` for executables)
* Spread the docs between build customization and packaging sections
* Add cross-references
* Add a label so that `spack external find` is linked from the command reference.
* Add pmi support (required by ucx, ofi, and gni backends)
* Add support for ucx backend
* Add dependency on MPI for pmi=simplepmi, slurmpmi, or slurmpmi2
* Remove charmpp as an MPI provider since the changes in this PR can
add MPI as a dependency (mentioned previously)
* Install into transport_protocol-OS-arch subdirectory to match
default charmpp installation behavior (which helps dependents find it)
- add docstrings and make parameter names consistent in `relocate.py`
- Make `replace_prefix_*` and other functions private (as they are implementation details)
- remove unused function _replace_prefix_nullterm()
- Add unit tests for `relocate.py` functions
- add patchelf to Travis and use it during tests
- add hello_world fixture with a compiled binary, so we can test relocation
After migrating to `travis-ci.com`, we saw I/O issues in our tests --
tests that relied on `capfd` and `capsys` were failing. We've also seen
this in GitHub actions, and it's kept us from switching to them so far.
Turns out that the issue is that using streams like `sys.stdout` as
default arguments doesn't play well with `pytest` and output redirection,
as `pytest` changes the values of `sys.stdout` and `sys.stderr`. if these
values are evaluated before output redirection (as they are when used as
default arg values), output won't be captured properly later.
- [x] replace all stream default arg values with `None`, and only assign stream
values inside functions.
- [x] fix tests we didn't notice were relying on this erroneous behavior
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.

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

provided externally). See #15666 for an example.

* One test in concretize.py was clearing a nonexistent cache
(PackagePrefs._packages_config_cache). This reference has been
removed.

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.
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).
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 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.

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.

* For tests that use the real Spack package repository, the config
needs to avoid using MPI providers that are not intended to be

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.

- `get_relative_elf_rpaths`
- `get_normalized_elf_rpaths`
- `set_placeholder`
mainly to be more consistent with practices used in other
parts of the code and to simplify functions locally. It also
adds or reworks unit tests for these functions and extends

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`
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.

Update compiler config with bootstrapped compiler when it was already installed and added config defaults to code so mutable_config test fixture works.
To specify an environment for a comment, the user can specify
"spack -e <env>". The documentation incorrectly specified "-E" (which
is actually used to ignore any implicit use of environments).
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)
Since #16132, we've consolidated the setting of FORCE_UNSAFE_CONFIGURE to
`autotools.py`, so we don't need to use it in packages like `coreutils`,
in our commands, or in our container recipes.
- [x] Remove FORCE_UNSAFE_CONFIGURE from packages
- [x] Remove FORCE_UNSAFE_CONFIGURE from container recipes
- [x] Remove FORCE_UNSAFE_CONFIGURE from `spack ci` command
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`.

`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.

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.
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

verifier when it resets.

the tests reset the last seen verifier in between tests that use the
database fixture.

Currently, to force Spack to use an external MPI, you have to specify `buildable: False`
for every MPI provider in Spack in your packages.yaml file. This is both tedious and
fragile, as new MPI providers can be added and break your workflow when you do a
git pull.
This PR allows you to specify an entire virtual dependency as non-buildable, and
specify particular implementations to be built:
```
packages:
all:
providers:
mpi: [mpich]
mpi:
buildable: false
paths:
mpich@3.2 %gcc@7.3.0: /usr/packages/mpich-3.2-gcc-7.3.0
```
will force all Spack builds to use the specified `mpich` install.
Removed provider_index use of 'import from' and refactored a few routines to a further subclassing of _IndexBase for implementing user defined bindings of provider specs.
* relocate: removed import from statements
* relocate: renamed *Exception to *Error
This aims at consistency in naming with both
the standard library (ValueError, AttributeError,
etc.) and other errors in 'spack.error'.

* relocate: simplified search function by un-nesting conditionals
The search function that searches for patchelf has been
refactored to remove deeply nested conditionals.

Our unit tests run many times. Any unit test which actually installs
a package (which involves fetching code on the internet) is a severe
bug because it runs an installation many times (i.e. re-downloading
the same package for each version of Python that we run unit tests
for).
This reverts commit 25893f1, which added tests that install real
packages.
If the Python used by Spack does not include Setuptools, then
'spack test' will fail because Spack's vendored pytest dependency
imports and uses Setuptools in some of its functions. It turns out
that Spack doesn't use the functionality those methods enable, so
this PR removes those functions and thereby allows 'spack test' to
run without Setuptools.
For any Spack test using Spack's YAML configuration, avoid using real
Spack configuration that has been cached by other tests and Spack
startup logic. Previously this was only done for tests using
'mutable_config' (i.e. those which expected to *change* the
configuration of Spack), but in fact all tests that read Spack config
should use it.
This was an issue when running tests within an environment, because
compiler configuration ends up being queried earlier, and the user's
real config "leaks" into the cache. Outside an environment, the cache
is never set until tests touch it, so we weren't seeing this issue.

Spack currently cannot run as a background process uninterrupted because some of the logging functions used in the install method (especially to create the dynamic verbosity toggle with the v key) cause the OS to issue a SIGTTOU to Spack when it's backgrounded.
This PR puts the necessary gatekeeping in place so that Spack doesn't do anything that will cause a signal to stop the process when operating as a background process.

Bug: Spack hangs on some Cray machines
Reason: The TERM environment variable is necessary to run bash -lc "echo $CRAY_CPU_TARGET", but we run that command within env -i, which wipes the environment.

When trying to use an upstream Spack repository, as of f2aca86 Spack

until length is the same as old prefix.

Bug: Spack hangs on some Cray machines
Reason: The TERM environment variable is necessary to run bash -lc "echo $CRAY_CPU_TARGET", but we run that command within env -i, which wipes the environment.
Fix: Manually forward the TERM environment variable to env -i /bin/bash -lc "echo $CRAY_CPU_TARGET"
- [x] move some logic for handling virtual packages from the `spack
dependencies` command into `spack.package.possible_dependencies()`
- [x] rework possible dependencies tests so that expected and actual
output are on the left/right respectively
When trying to use an upstream Spack repository, as of f2aca86 Spack
was attempting to write to the upstream DB based on a new metadata
directory added in that commit. Upstream DBs are read-only, so this
should not occur.
This adds a check to prevent Spack from writing to the upstream DB

Add a 'define_from_variant` helper function to CMake-based Spack
packages to convert package variants into CMake arguments. For
example:
args.append('-DFOO=%s' % ('ON' if '+foo' in self.spec else 'OFF'))
can be replaced with:
args.append(self.define_from_variant('foo'))
The following conversions are handled automatically:
* Flag variants will be converted to CMake booleans
* Multivalued variants will be converted to semicolon-separated strings
* Other variant values are converted to CMake string arguments
This also adds a 'define' helper method to convert any variable to
a CMake argument. It has the same conversion rules as
'define_from_variant' (but operates directly on values rather than
requiring the user to supply the name of a package variant).
* Buildcache: Install into non-default directory layouts
Store a dictionary mapping of original dependency prefixes to dependency hashes
Use the loaded spec to grab the new dependency prefixes in the new directory layout.
Map the original dependency prefixes to the new dependency prefixes using the dependency hashes.
Use the dependency prefixes map to replace original rpaths with new rpaths preserving the order.
For mach-o binaries, use the dependency prefixes map to replace the dependency library entires for libraries and executables and the replace the library id for libraries.
On Linux, patchelf is used to replace the rpaths of elf binaries.
On macOS, install_name_tool is used to replace the rpaths and dependency libraries of mach-o binaries and the id of mach-o libraries.
On Linux, macholib is used to replace the dependency libraries of mach-o binaries and the id of mach-o libraries.
Binary text with padding replacement is attempted for all binaries for the following paths:
spack layout root
spack prefix
sbang script location
dependency prefixes
package prefix
Text replacement is attempted for all text files using the paths above.
Symbolic links to the absolute path of the package install prefix are replaced, all others produce warnings.
PR #15212 added a new connect_timeout option that can be overridden
using fetch_options but had to specified per-version. This adds a new
per-package variable that can be used to override fetch_options for
all versions in the package. This includes connect_timeout as well
as 'cookie' (e.g. for the jdk package).
Packages can combine package-level fetch_options with per-version
fetch_options, in which case the version fetch_options completely
override the package-level fetch_options.
This commit includes tests for the added behavior.
fixes#15449
Before this PR a call to pkg.url_for_version was modifying
class attributes determining different results for subsequents
calls and an error when the urls was empty.
* add --skip-unstable-versions option to 'spack mirror create' which skips sources/resource for packages if their version is not stable (i.e. if they are the head of a git branch rather than a fixed commit)
* '--skip-unstable-versions' should skip all VCS sources/resources, not just those which are not cachable
Allows spack.config InternalConfigScope and Configuration.set() to
handle keys with trailing ':' to indicate replacement vs merge
behavior with respect to lower priority scopes.
Lists may now be replaced rather than merged (this behavior was
previously only available for dictionaries).
This commit adds tests for the new behavior.
Testing the install StopIteration exception resulted in an attribute error:
AttributeError: 'StopIteration' object has no attribute 'message'
This PR adds a unit test and resolves that error.
This recovers the old behavior of replace_prefix_bin that was
modified to work with elf binaries by prefixing os.sep to new prefix
until length is the same as old prefix.
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.
Spack's fflags are meant for both f77 and fc. Therefore, they must
be passed as FFLAGS and FCFLAGS to the configure scripts of
Autotools-based packages.
The distributed build PR (#13100) -- did not check the install status of dependencies when using the `--only package` option so would refuse to install a package with the claim that it had uninstalled dependencies whether that was the case or not.
- [x] add install status checks for the `--only package` case.
- [x] add initial set of tests
connect_timeout can be used to increase the time Spack waits for the
server to answer. This can be used to work around slow connections or
servers.

* CudaPackage: add support for Tesla K80 and older CUDA
* Flake8 fixes
* Fix cuda_arch when no arch is set
* Fine-tune cuda_arch=37,50 supported CUDA versions
* CUDA 6.5+ supports SM_37
* Add @svenevs as a maintainer
The new build process, introduced in #13100 , relies on a spec's dependents in addition to their dependencies. Loading a spec from a yaml file was not initializing the dependents.
- [x] populate dependents when loading from yaml
* Buildcache command: add install option -o/--otherarch
This will allow matching specs from other archs, for example
installing macOS buildcaches on linux hosts.
* spack commands --update-completion
args.specs is a list, which results in output like this:
```
eval `spack load --sh ['libxml2', 'xz']`
```
We want this instead:
```
eval `spack load --sh libxml2 xz`
```

* Emit a sensible error message if compiler's target is overly specific
fixes#14798fixes#13733
Compiler specifications require a generic architecture family as
their target. This commit improves the error message that is
displayed to users if they edit compilers.yaml and use an overly
specific name.
The hashing logic looks for function calls that are Spack directives.
It expects that when a Spack directive is used that it is referenced
directly by name, and that the directive function is not itself
retrieved by calling another function. When the hashing logic
encountered a function call where the function was determined
dynamically, it would fail (attempting to access a name attribute
that does not happen to exist in this case).
This updates the hashing logic to filter out function calls where the
function is determined dynamically when looking for uses of Spack
directives.
Spack now requires an exact match of the compiler version
requested by the user. A loose constraint can be given to
Spack by using a version range instead of a concrete version
(e.g. 4.5: instead of 4.5).
Sometimes one needs to preserve the (relative order) of
mtimes on installed files. So it's better to just copy
over all the metadata from the source tree to the install
tree. If permissions need fixing, that will be done anyway
afterwards.
One major use case are resource()s:
They're unpacked in one place and then copied to their
final place using install_tree(). If the resource is a
source tree using autoconf/automake, resetting mtimes
uncorrectly might force unwanted autoconf/etc calls.
If the mimetype returned from `file -h -b --mime-type` contains slashes
in its subtype, the tuple returned from `spack.relocate.mime_type` will
have a size larger than two, which leads to errors.

Fixes#9394Closes#13217.
## Background
Spack provides the ability to enable/disable parallel builds through two options: package `parallel` and configuration `build_jobs`. This PR changes the algorithm to allow multiple, simultaneous processes to coordinate the installation of the same spec (and specs with overlapping dependencies.).
The `parallel` (boolean) property sets the default for its package though the value can be overridden in the `install` method.
Spack's current parallel builds are limited to build tools supporting `jobs` arguments (e.g., `Makefiles`). The number of jobs actually used is calculated as`min(config:build_jobs, # cores, 16)`, which can be overridden in the package or on the command line (i.e., `spack install -j <# jobs>`).
This PR adds support for distributed (single- and multi-node) parallel builds. The goals of this work include improving the efficiency of installing packages with many dependencies and reducing the repetition associated with concurrent installations of (dependency) packages.
## Approach
### File System Locks
Coordination between concurrent installs of overlapping packages to a Spack instance is accomplished through bottom-up dependency DAG processing and file system locks. The runs can be a combination of interactive and batch processes affecting the same file system. Exclusive prefix locks are required to install a package while shared prefix locks are required to check if the package is installed.
Failures are communicated through a separate exclusive prefix failure lock, for concurrent processes, combined with a persistent store, for separate, related build processes. The resulting file contains the failing spec to facilitate manual debugging.
### Priority Queue
Management of dependency builds changed from reliance on recursion to use of a priority queue where the priority of a spec is based on the number of its remaining uninstalled dependencies.
Using a queue required a change to dependency build exception handling with the most visible issue being that the `install` method *must* install something in the prefix. Consequently, packages can no longer get away with an install method consisting of `pass`, for example.
## Caveats
- This still only parallelizes a single-rooted build. Multi-rooted installs (e.g., for environments) are TBD in a future PR.
Tasks:
- [x] Adjust package lock timeout to correspond to value used in the demo
- [x] Adjust database lock timeout to reduce contention on startup of concurrent
`spack install <spec>` calls
- [x] Replace (test) package's `install: pass` methods with file creation since post-install
`sanity_check_prefix` will otherwise error out with `Install failed .. Nothing was installed!`
- [x] Resolve remaining existing test failures
- [x] Respond to alalazo's initial feedback
- [x] Remove `bin/demo-locks.py`
- [x] Add new tests to address new coverage issues
- [x] Replace built-in package's `def install(..): pass` to "install" something
(i.e., only `apple-libunwind`)
- [x] Increase code coverage
* Buildcache creation change the way prefix is copied to workdir.
* install_tree copies hardlinked files
* tarfile creates hardlinked files on extraction.
* create a temporary tarfile from prefix and extract it to workdir
* Use temp tarfile to move workdir to prefix to preserve hardlinks instead of copying
