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.
* Separate Apple Clang from LLVM Clang
Apple Clang is a compiler of its own. All places
referring to "-apple" suffix have been updated.
* Hack to use a dash in 'apple-clang'
To be able to use autodoc from Sphinx we need
a valid Python name for the module that contains
Apple's Clang code.
* Updated packages to account for the existence of apple-clang

This commit removes the DYLD_LIBRARY_PATH variable from the default
modules.yaml for darwin. The rationale behind deleting this
environment variable is that paths in this environment variable take
precedence over the default locations of libraries (usually the
install path of the library), which can lead to linking errors in some
circumstances. For example, executables intended to link with Apple's
system BLAS and LAPACK will instead link to a spack-installed
implementation (e.g., OpenBLAS), causing runtime errors.
These errors are resolved by instead relying on paths set in
DYLD_FALLBACK_LIBRARY_PATH, which is lower in precedence than default
locations of libraries.
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.

Every path in CPATH is equivalent to a -I path to the compiler,
while every path in *_INCLUDE_PATH is equivalent to -isystem.
The latter avoids the noise due to warnings coming from 3rd party
libraries that a project depends on.
Added INCLUDE env variable (Intel Fortran, .mod files)
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.

## 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
Add a configuration option to suppress gpg warnings during binary
package verification. This only suppresses warnings: a gpg failure
will still fail the install. This allows users who have already
explicitly trusted the gpg key they are using to avoid seeing
repeated warnings that it is self-signed.
Add a new entry in `config.yaml`:
config:
shared_linking: 'rpath'
If this variable is set to `rpath` (the default) Spack will set RPATH in ELF binaries. If set to `runpath` it will set RUNPATH.
Details:
* Spack cc wrapper explicitly adds `--disable-new-dtags` when linking
* cc wrapper also strips `--enable-new-dtags` from the compile line
when disabling (and vice versa)
* We specifically do *not* add any dtags flags on macOS, which uses
Mach-O binaries, not ELF, so there's no RUNPATH)
While the build environment already takes share/pkgconfig into account,
the generated module files etc. only consider lib/pkgconfig and
lib64/pkgconfig.
Dotkit is being used only at a few sites and has been deprecated on new
machines. This commit removes all the code that provide support for the
generation of dotkit module files.
A new validator named "deprecatedProperties" has been added to the
jsonschema validators. It permits to prompt a warning message or exit
with an error if a property that has been marked as deprecated is
encountered.
* Removed references to dotkit in the docs
* Removed references to dotkit in setup-env-test.sh
* Added a unit test for the 'deprecatedProperties' schema validator
* When cleaning the stage root, only remove directories that appear
to be used for staging Spack packages. Previously Spack was clearing
all directories in the stage root, which could remove content not
related to Spack if the user chose a staging root which contains
files/directories not managed by Spack.
* The documentation is updated with warnings about choosing a stage
directory that is only managed by Spack (although generally the
check added in this PR for "spack clean" should avoid removing
content that was not created by Spack)
* The default stage directory (in config.yaml) is now
$tempdir/$user/spack-stage and the logic is updated to omit the
$user portion of this path if $tempdir already contains a $user
directory.
* When creating stage root assign user read/write permissions to all
directories in the path under $user. Previously Spack was assigning
the permissions of the first existing parent directory
Fixes#11163
The goal of this work is to simplify stage directory structures by eliminating use of symbolic links. This means, among other things, that` $spack/var/spack/stage` will no longer be the core staging directory. Instead, the first accessible `config:build_stage` path will be used.
Spack will no longer automatically append `spack-stage` (or the like) to configured build stage directories so the onus of distinguishing the directory from other work -- so the other work is not automatically removed with a `spack clean` operation -- falls on the user.
The original packaging, with openfoam as a virtual and with
openfoam-com, openfoam-org and openfoam-extend as
providers, adds an obfuscation layer without any benefit.
- Rename `openfoam-com` to `openfoam`, and remove the
`openfoam` virtual package.
* config:build_jobs now controls the number of parallel jobs to spawn during
builds, but cannot ever exceed the number of cores on the machine.

This spack command adds a new schema for a file which describes the
builder containers available, along with the compilers availabe on
each builder. The release-jobs command then generates the .gitlab-ci.yml
file by first expanding the release spec set, concretizing each spec
(in an appropriate docker container if --this-machine-only argument is
not provided on command line), and then combining and staging all the
concrete specs as jobs to be run by gitlab.
* Remove /nfs/tmp2 from default configuration
* /nfs/tmp2 is going away from LC... and doesn’t exist for the rest of the world.
* update documentation to remove /nfs/tmp2 as well
* Introduce FFTW2 and FFT3 providers for Intel-MKL and FFTW Spack packages.
* make fftw default package for fftw-api virtual package
* virtual package test assertion now provides location of default virtual packages.
* Change name of virtual package to fftw-api and used versioned interface.
* Add a build_language config.yaml option which controls the language
of compiler messages
* build_language defaults to "C", in which case the compiler messages
will be in English. This allows Spack log parsing to detect and
highlight error messages (since the regular expressions to find
error messages are in English)
* The user can use the default language in their environment by setting
the build_language config variable to null or ''
Spack can now be configured to assign permissions to the files installed by a package.
In the `packages.yaml` file under `permissions`, the attributes `read`, `write`, and `group` control the package permissions. These attributes can be set per-package, or for all packages under `all`. If permissions are set under `all` and for a specific package, the package-specific settings take precedence. The `read` and `write` attributes take one of `user`, `group`, and `world`.
packages:
all:
permissions:
write: group
group: spack

permissions:
read: group
group: my_team
Fixes#9166
This is intended to reduce errors related to lock timeouts by making
the following changes:
* Improves error reporting when acquiring a lock fails (addressing
#9166) - there is no longer an attempt to release the lock if an
acquire fails
* By default locks taken on individual packages no longer have a
timeout. This allows multiple spack instances to install overlapping
dependency DAGs. For debugging purposes, a timeout can be added by
setting 'package_lock_timeout' in config.yaml
* Reduces the polling frequency when trying to acquire a lock, to
reduce impact in the case where NFS is overtaxed. A simple
adaptive strategy is implemented, which starts with a polling
interval of .1 seconds and quickly increases to .5 seconds
(originally it would poll up to 10^5 times per second).
A test is added to check the polling interval generation logic.
* The timeout for Spack's whole-database lock (e.g. for managing
information about installed packages) is increased from 60s to
120s
* Users can configure the whole-database lock timeout using the
'db_lock_timout' setting in config.yaml
Generally, Spack locks (those created using spack.llnl.util.lock.Lock)
now have no timeout by default
This does not address implementations of NFS that do not support file
locking, or detect cases where services that may be required
(nfslock/statd) aren't running.
Users may want to be able to more-aggressively release locks when
they know they are the only one using their Spack instance, and they
encounter lock errors after a crash (e.g. a remote terminal disconnect
mentioned in #8915).
This commit adds 'libunwind' as the default 'unwind' provider in
spack. This preference should be overridden by the
darwin/packages.yaml file on macOS. Continues the changes discussed in
This commit adds default unwind providers to the default packages.yaml
for darwin. Compiler versions are supplied with the apple-unwind
package so that apple-unwind is only used with Apple's clang fork, and
not with LLVM's clang.
If the user sets "ccache: true" in spack's config.yaml, Spack will use an available
ccache executable when compiling c/c++ code. This feature is disabled by default
(i.e. "ccache: false") and the documentation is updated with how to enable
ccache support
