This changes Spack environments so that the YAML file associated with the environment is *only* written when necessary (i.e., if it is changed *by spack*). The lockfile is still written out as before.
There is a larger question here of which part of Spack should be responsible for setting defaults in config files, and how we can get rid of empty lists and data structures currently cluttering files like `compilers.yaml`. But that probably requires a rework of the default-setting validator in `spack.config`, as well as the code that uses `spack.config`. This will at least help for `spack.yaml`.

4af4487 added a mirror_id function to most FetchStrategy
implementations that is used to calculate resource locations in
mirrors. It left out BundleFetchStrategy which broke all packages
making use of BundlePackage (e.g. xsdk). This adds a noop
implementation of mirror_id to BundleFetchStrategy so that the
download/installation of BundlePackages can proceed as normal.

The `test_changed_files` in `test/cmd/flake8.py` was failing because it calls
`ArgumentParser.parse_args()` without arguments. Normally that would just
parse `sys.argv` but it seems to fail because of something in either `spack test`
or `pytest`. Call it with an empty array so that it doesn't try to touch`sys.argv`
at all.
- [x] allow `-d` spack option for `test_changed_files`
* docs: add a spack environment for building the docs
* docs: remove tutorial and link to spack-tutorial.readthedocs.io
The tutorial now has its own standalone website, versioned by instances
of the tutorial. Link to that instead of versioning it directly with Spack.
Support mirroring all packages with `spack mirror create --all`.
In this mode there is no concretization:
* Spack pulls every version of every package into the created mirror.
* It also makes multiple attempts for each package/version combination
(if there is a temporary connection failure).
* Continues if all attempts fail. i.e., this makes its best effort to
fetch evrerything, even if all attempts to fetch one package fail.
This also changes mirroring logic to prefer storing sources by their hash
or by a unique name derived from the source. For example:
* Archives with checksums are named by the sha256 sum, i.e.,
`archive/f6/f6cf3bd233f9ea6147b21c7c02cac24e5363570ce4fd6be11dab9f499ed6a7d8.tar.gz`
vs the previous `<package-name>-package-version>.tar.gz`
* VCS repositories are stored by a path derived from their URL,
e.g. `git/google/leveldb.git/master.tar.gz`.
The new mirror layout allows different packages to refer to the same
resource or source without duplicating that download in the
mirror/cache. This change is not essential to mirroring everything but is
expected to save space when mirroring packages that all use the same
resource.
The new structure of the mirror is:
```
<base directory>/
_source-cache/ <-- the _source-cache directory is new
archive/ <-- archives/resources/patches stored by hash
00/ <-- 2-letter sha256 prefix
002748bdd0319d5ab82606cf92dc210fc1c05d0607a2e1d5538f60512b029056.tar.gz

0173a74a515211997a3117a47e7b9ea43594a04b865b69da5a71c0886fa829ea.tar.gz

...
svn/ <-- each fetch strategy has its own subdirectory
...
openmpi/ <-- the remaining package directories have the old format
openmpi-1.10.1.tar.gz <-- human-readable name is symlink to _source-cache
```
In addition to the archive names as described above, `mirror create` now
also creates symlinks with the old format to help users understand which
package each mirrored archive is associated with, and to allow mirrors to
work with old spack versions. The symlinks are relative so the mirror
directory can still itself be archived.
Other improvements:
* `spack mirror create` will not re-download resources that have already
been placed in it.
* When creating a mirror, the resources downloaded to the mirror will not
be cached (things are not stored twice).
reindexing takes a significant amount of time, and there's no reason to
do it from DB version 0.9.3 to version 5. The only difference is that v5
can contain "deprecated_for" fields.
- [x] Add a `_skip_reindex` list at the start of `database.py`
- [x] Skip the reindex for upgrades in this list. The new version will
just be written to the file the first time we actually have to write
the DB out (e.g., after an install), and reads will still work fine.
Previously, spack would error out if we tried to fetch something with no
code, but that would prevent fetching dependencies. In particular, this
would fail:
spack fetch --dependencies xsdk
- [x] Instead of raising an error, just print a message that there is nothing
to be fetched for packages like xsdk that do not have code.
- [x] Make BundleFetchStrategy a bit more quiet about doing nothing.
We've had `spack spec --yaml` for a while, and we've had methods for JSON
for a while as well. We just haven't has a `--json` argument for `spack spec`.
- [x] Add a `--json` argument to `spack spec`, just like `--yaml`

Rename the `spack diy` command to `spack dev-build` to make the use case clearer.
The `spack diy` command has some useful functionality for developers using Spack to build their dependencies and configure/build/install the code they are developing. Developers do not notice it, partly because of the obscure name.
The `spack dev-build` command has a `-u/--until PHASE` option to stop after a given phase of the build. This can be used to configure your project, run cmake on your project, or similarly stop after any stage of the build the user wants. These options are analogous to the existing `spack configure` and `spack build` commands, but for developer builds.
To unify the syntax, we have deprecated the `spack configure` and `spack build` commands, and added a `-u/--until PHASE` option to the `spack install` command as well.
The functionality in `spack dev-build` (specifically `spack dev-build -u cmake`) may be able to supersede the `spack setup` command, but this PR does not deprecate that command as that will require slightly more thought.
fd58c98 formats the `Stage`'s `archive_path` in `Stage.archive` (as part of `web.push_to_url`). This is not needed and if the formatted differs from the original path (for example if the archive file name contains a URL query suffix), then the copy fails.
This removes the formatting that occurs in `web.push_to_url`.
We should figure out a way to handle bad cases like this *and* to have nicer filenames for downloaded files. One option that would work in this particular case would be to also pass `-J` / `--remote-header-name` to `curl`. We'll need to do follow-up work to determine if we can use `-J` everywhere.

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)
`spack deprecate` allows for the removal of insecure packages with minimal impact to their dependents. It allows one package to be symlinked into the prefix of another to provide seamless transition for rpath'd and hard-coded applications using the old version.
Example usage:
spack deprecate /hash-of-old-openssl /hash-of-new-openssl
The spack deprecate command is designed for use only in extroardinary circumstances. The spack deprecate command makes no promises about binary compatibility. It is up to the user to ensure the replacement is suitable for the deprecated package.
Previously this command only showed total counts for each regular
expression. This doesn't give you a sense of which regexes are working
well and which ones are not. We now display the number of right, wrong,
and total URL parses per regex.
It's easier to see where we might improve the URL parsing with this
change.
This updates the configuration loading/dumping logic (now called
load_config/dump_config) in spack_yaml to preserve comments (by using
ruamel.yaml's RoundTripLoader). This has two effects:
* environment spack.yaml files expect to retain comments, which
load_config now supports. By using load_config, users can now use the
':' override syntax that was previously unavailable for environment
configs (but was available for other config files).
* config files now retain user comments by default (although in cases
where Spack updates/overwrites config, the comments can still be
removed).
Details:
* Subclasses `RoundTripLoader`/`RoundTripDumper` to parse yaml into
ruamel's `CommentedMap` and analogous data structures
* Applies filename info directly to ruamel objects in cases where the
updated loader returns those
* Copies management of sections in `SingleFileScope` from #10651 to allow
overrides to occur
* Updates the loader/dumper to handle the processing of overrides by
specifically checking for the `:` character
* Possibly the most controversial aspect, but without that, the parsed
objects have to be reconstructed (i.e. as was done in
`mark_overrides`). It is possible that `mark_overrides` could remain
and a deep copy will not cause problems, but IMO that's generally
worth avoiding.
* This is also possibly controversial because Spack YAML strings can
include `:`. My reckoning is that this only occurs for version
specifications, so it is safe to check for `endswith(':') and not
('@' in string)`
* As a consequence, this PR ends up reserving spack yaml functions
load_config/dump_config exclusively for the purpose of storing spack
config
`test_envoronment_status()` was printing extra output during tests.
- [x] disable output only for `env('status')` calls instead of disabling
it for the whole test.
This PR ensures that environment activation sets all environment variables set by the equivalent `module load` operations, except that the spec prefixes are "rebased" to the view associated with the environment.
Currently, Spack blindly adds paths relative to the environment view root to the user environment on activation. Issue #12731 points out ways in which this behavior is insufficient.
This PR changes that behavior to use the `setup_run_environment` logic for each package to augment the prefix inspections (as in Spack's modulefile generation logic) to ensure that all necessary variables are set to make use of the packages in the environment.
See #12731 for details on the previous problems in behavior.
This PR also updates the `ViewDescriptor` object in `spack.environment` to have a `__contains__` method. This allows for checks like `if spec in self.default_view`. The `__contains__` operator for `ViewDescriptor` objects checks whether the spec satisfies the filters of the View descriptor, not whether the spec is already linked into the underlying `FilesystemView` object.
This PR ensures that on Darwin we always append /sbin and /usr/sbin to PATH, if they are not already present, when looking for sysctl.
* Make sure we look into /sbin and /usr/sbin for sysctl
* Refactor sysctl for better readability

These changes update our gcc microarchitecture descriptions based on manuals found here https://gcc.gnu.org/onlinedocs/ and assuming that new architectures are not added during patch releases.
This extends Spack functionality so that it can fetch sources and binaries from-, push sources and binaries to-, and index the contents of- mirrors hosted on an S3 bucket.
High level to-do list:
- [x] Extend mirrors configuration to add support for `file://`, and `s3://` URLs.
- [x] Ensure all fetching, pushing, and indexing operations work for `file://` URLs.
- [x] Implement S3 source fetching
- [x] Implement S3 binary mirror indexing
- [x] Implement S3 binary package fetching
- [x] Implement S3 source pushing
- [x] Implement S3 binary package pushing
Important details:
* refactor URL handling to handle S3 URLs and mirror URLs more gracefully.
- updated parse() to accept already-parsed URL objects. an equivalent object
is returned with any extra s3-related attributes intact. Objects created with
urllib can also be passed, and the additional s3 handling logic will still be applied.
* update mirror schema/parsing (mirror can have separate fetch/push URLs)
* implement s3_fetch_strategy/several utility changes
* provide more feature-complete S3 fetching
* update buildcache create command to support S3
* Move the core logic for reading data from S3 out of the s3 fetch strategy and into
the s3 URL handler. The s3 fetch strategy now calls into `read_from_url()` Since
read_from_url can now handle S3 URLs, the S3 fetch strategy is redundant. It's
not clear whether the ideal design is to have S3 fetching functionality in a fetch
strategy, directly implemented in read_from_url, or both.
* expanded what can be passed to `spack buildcache` via the -d flag: In addition
to a directory on the local filesystem, the name of a configured mirror can be
passed, or a push URL can be passed directly.
fixes#13073
Since #3206 was merged bootstrapping environment-modules was using the architecture of the current host or the best match supported by the default compiler. The former case is an issue since shell integration was looking for a spec targeted at the host microarchitecture.

2. Look for generic targets in shell integration scripts
3. Add a new entry in Travis to test shell integration
Custom string versions for compilers were raising a ValueError on
conversion to int. This commit fixes the behavior by trying to detect
the underlying compiler version when in presence of a custom string
version.
* Refactor code that deals with custom versions for better readability
* Partition version components with a regex
* Fix semantic of custom compiler versions with a suffix
* clang@x.y-apple has been special-cased
* Add unit tests
We've been doing this for quite a while now, and it does not seem to
cause issues.
- [x] Switch the noisy warning to a debug to make Spack a bit quieter
while building.
* Added architecture specific optimization flags for Clang / LLVM
* Disallow compiler optimizations for mixed toolchains
* We emit a warning when building for a mixed toolchain
* Fixed issues with suffixed versions of compilers; Apple's Clang will,
for the time being, fall back on x86-64 for every compilation.
* Methods setting the environment now do it separately for build and run
Before this commit the `*_environment` methods were setting
modifications to both the build-time and run-time environment
simultaneously. This might cause issues as the two environments
inherently rely on different preconditions:
1. The build-time environment is set before building a package, thus
the package prefix doesn't exist and can't be inspected
2. The run-time environment instead is set assuming the target package
has been already installed
Here we split each of these functions into two: one setting the
build-time environment, one the run-time.
We also adopt a fallback strategy that inspects for old methods and
executes them as before, but prints a deprecation warning to tty. This
permits to port packages to use the new methods in a distributed way,
rather than having to modify all the packages at once.
* Added a test that fails if any package uses the old API
Marked the test xfail for now as we have a lot of packages in that
state.
* Added a test to check that a package modified by a PR is up to date
This test can be used any time we deprecate a method call to ensure
that during the first modification of the package we update also
the deprecated calls.
* Updated documentation
Python 3 metaclasses have a `__prepare__` method that lets us save the
class's dictionary before it is constructed. In Python 2 we had to walk
up the stack using our `caller_locals()` method to get at this. Using
`__prepare__` is much faster as it doesn't require us to use `inspect`.
This makes multimethods use the faster `__prepare__` method in Python3,
while still using `caller_locals()` in Python 2. We try to reduce the
use of caller locals using caching to speed up Python 2 a little bit.
Our importer was always parsing from source (which is considerably
slower) because the source size recorded in the .pyc file differed from
the size of the input file.
Override path_stats in the prepending importer to fool it into thinking
that the source size is the size *with* the prepended code.
Since the backup file is only created on the first invocation, it will
contain the original file without any modifications. Further invocations
will then read the backup file, effectively reverting prior invocations.
This can be reproduced easily by trying to install likwid, which will
try to install into /usr/local. Work around this by creating a temporary
file to read from.
* This updates stage names to use "spack-stage-" as a prefix.
This avoids removing non-Spack directories in "spack clean" as
c141e99 did (in this case so long as they don't contain the
prefix "spack-stage-"), and also addresses a follow-up issue
where Spack stage directories were not removed.
* Spack now does more-stringent checking of expected permissions for
staging directories. For a given stage root that includes a user
component, all directories before the user component that are
created by Spack are expected to match the permissions of their
parent; the user component and all deeper directories are expected
to be accessible to the user (read/write/execute).
This feature generates a verification manifest for each installed
package and provides a command, "spack verify", which can be used to
compare the current file checksums/permissions with those calculated
at installed time.
Verification includes
* Checksums of files
* File permissions
* Modification time
* File size
Packages installed before this PR will be skipped during verification.
To verify such a package you must reinstall it.
The spack verify command has three modes.
* With the -a,--all option it will check every installed package.
* With the -f,--files option, it will check some specific files,
determine which package they belong to, and confirm that they have
not been changed.
* With the -s,--specs option or by default, it will check some
specific packages that no files havae changed.
fixes#13005
This commit fixes an issue with the name of the root directory for
module file hierarchies. Since #3206 the root folder was named after
the microarchitecture used for the spec, which is too specific and
not backward compatible for lmod hierarchies. Here we compute the
root folder name using the target family instead of the target name
itself and we add target information in the 'whatis' portion of the
module file.
From Python docs:
--
'surrogateescape' will represent any incorrect bytes as code points in
the Unicode Private Use Area ranging from U+DC80 to U+DCFF. These
private code points will then be turned back into the same bytes when
the surrogateescape error handler is used when writing data. This is
useful for processing files in an unknown encoding.
--
This will allow us to process files with unknown encodings.
To accommodate the case of self-extracting bash scripts, filter_file
can now stop filtering text input if a certain marker is found. The
marker must be passed at call time via the "stop_at" function argument.
At that point the file will be reopened in binary mode and copied
verbatim.
* use "surrogateescape" error handling to ignore unknown chars
* permit to stop filtering if a marker is found
* add unit tests for non-ASCII and mixed text/binary files
- Add a test that verifies checksums on all packages
- Also add an attribute to packages that indicates whether they need a
manual download or not, and add an exception in the tests for these
packages until we can verify them.
Both floating-point and NEON are required in all standard ARMv8
implementations. Theoretically though specialized markets can support
no NEON or floating-point at all. Source:
https://developer.arm.com/docs/den0024/latest/aarch64-floating-point-and-neon
On the other hand the base procedure call standard for Aarch64
"assumes the availability of the vector registers for passing
floating-point and SIMD arguments". Further "the Arm 64-bit
architecture defines two mandatory register banks: a general-purpose
register bank which can be used for scalar integer processing and
pointer arithmetic; and a SIMD and Floating-Point register bank".
Source:
https://developer.arm.com/docs/ihi0055/latest/procedure-call-standard-for-the-arm-64-bit-architecture
This makes customization of Aarch64 with no NEON instruction set
available so unlikely that we can consider them a feature of the
generic family.
This PR adds a 'concretize' entry to an environment's spec.yaml file
which controls how user specs are concretized. By default it is
set to 'separately' which means that each spec added by the user is
concretized separately (the behavior of environments before this PR).
If set to 'together', the environment will concretize all of the
added user specs together; this means that all specs and their
dependencies will be consistent with each other (for example, a
user could develop code linked against the set of libraries in the
environment without conflicts).
If the environment was previously concretized, this will re-concretize
all specs, in which case previously-installed specs may no longer be
used by the environment (in this sense, adding a new spec to an
environment with 'concretize: together' can be significantly more
expensive).
The 'concretize: together' setting is not compatible with Spec
matrices; this PR adds a check to look for multiple instances of the
same package added to the environment and fails early when
'concretize: together' is set (to avoid confusing messages about
conflicts later on).
While the build environment already takes share/pkgconfig into account,
the generated module files etc. only consider lib/pkgconfig and
lib64/pkgconfig.
When removing support for dotkit in #11986 the code trying to set the
paths of the various module files was not updated to skip it. This
results in a failure because of a key error after the deprecation
warning is displayed to user.
This commit fixes the issue and adds a unit test for regression.
Note that code for Spack chains has been updated accordingly but
no unit test has been added for that case.
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
fixes#12915closes#12916
Since Spack has support for specific targets it might happen that
software is built for targets that are not exactly the host because
it was either an explicit user request or the compiler being used is
too old to support the host.
Modules for different targets are written into different directories
and by default Spack was adding to MODULEPATH only the directory
corresponding to the current host. This PR modifies this behavior to
add all the directories that are **compatible** with the current host.
Sometimes when remove_file is called on a link, that link is missing
(perhaps ctrl-C happened halfway through a previous action). As
removing a non-existent file is no problem, this patch changes the
behavior so Spack continues rather than stopping with an error.
Currently you would see
ValueError: /path/to/dir is not a link tree!
and now it continues with a warning.
bin/spack now needs to have a "-*- python -*-" line after the shebang, so
that emacs will interpret it as a python file instead of as a shell
script. Add one line to the license check limit to accommodate this.
The output of subprocess.check_output is a byte string in Python 3. This causes dictionary lookup to fail later on.
A try-except around this function prevented this error from being noticed. Removed this so that more errors can propagate out.
Preferred targets were failing because we were looking them up by
Microarchitecture object, not by string.
- [x] Add a call to `str()` to fix target lookup.
- [x] Add a test to exercise this part of concretization.
- [x] Add documentation for setting `target` in `packages.yaml`

This PR adds the creation of the remaining (16) templates to ensure we can create them with expected content. The goal is to facilitate catching during testing.
Spack doesn't need `requests`, and neither does `jsonschema`, but
`jsonschema` tries to import it, and it'll succeed if `requests` is on
your machine (which is likely, given how popular it is). This commit
removes the import to improve Spack's startup time a bit.
On a mac with SSD, the import of requests is ~28% of Spack's startup time
when run as `spack --print-shell-vars sh,modules` (.069 / .25 seconds),
which is what `setup-env.sh` runs.
On a Linux cluster where Python is mounted from NFS, this reduces
`setup-env.sh` source time from ~1s to .75s.
Note: This issue will be eliminated if we upgrade to a newer `jsonschema`
(we'd need to drop Python 2.6 for that). See
https://github.com/Julian/jsonschema/pull/388.
- This is needed to support Cray machines -- we need an architecture
mic_knl > x86_64
- We used Cray's naming scheme for this target to make it work seamlessly
with the module-based detection sccheme on Cray. mic_knl is pretty
much dead, so this will be the last succh target. We will need to work
wtih Cray and other vendors in the future.
Seamless translation from 'target=<generic>' to either
- target.family == <generic> (in methods)
- 'target=<generic>:' (in directives)
Also updated docs to show ranges in directives.
Spack can now:
- label ppc64, ppc64le, x86_64, etc. builds with specific
microarchitecture-specific names, like 'haswell', 'skylake' or
'icelake'.
- detect the host architecture of a machine from /proc/cpuinfo or similar
tools.
- Understand which microarchitectures are compatible with which (for
binary reuse)
- Understand which compiler flags are needed (for GCC, so far) to build
binaries for particular microarchitectures.
All of this is managed through a JSON file (microarchitectures.json) that
contains detailed auto-detection, compiler flag, and compatibility
information for specific microarchitecture targets. The `llnl.util.cpu`
module implements a library that allows detection and comparison of
microarchitectures based on the data in this file.
The `target` part of Spack specs is now essentially a Microarchitecture
object, and Specs' targets can be compared for compatibility as well.
This allows us to label optimized binary packages at a granularity that
enables them to be reused on compatible machines. Previously, we only
knew that a package was built for x86_64, NOT which x86_64 machines it
was usable on.
Currently this feature supports Intel, Power, and AMD chips. Support for
ARM is forthcoming.
Specifics:
- Add microarchitectures.json with descriptions of architectures
- Relaxed semantic of compiler's "target" attribute. Before this change
the semantic to check if a compiler could be viable for a given target
was exact match. This made sense as the finest granularity of targets
was architecture families. As now we can target micro-architectures,
this commit changes the semantic by interpreting as the architecture
family what is stored in the compiler's "target" attribute. A compiler
is then a viable choice if the target being concretized belongs to the
same family. Similarly when a new compiler is detected the architecture
family is stored in the "target" attribute.
- Make Spack's `cc` compiler wrapper inject target-specific flags on the
command line
- Architecture concretization updated to use the same algorithm as
compiler concretization
- Micro-architecture features, vendor, generation etc. are included in
the package hash. Generic architectures, such as x86_64 or ppc64, are
still dumped using the name only.
- If the compiler for a target is not supported exit with an intelligible
error message. If the compiler support is unknown don't try to use
optimization flags.
- Support and define feature aliases (e.g., sse3 -> ssse3) in
microarchitectures.json and on Microarchitecture objects. Feature
aliases are defined in targets.json and map a name (the "alias") to a
list of rules that must be met for the test to be successful. The rules
that are available can be extended later using a decorator.
- Implement subset semantics for comparing microarchitectures (treat
microarchitectures as a partial order, i.e. (a < b), (a == b) and (b <
a) can all be false.
- Implement logic to automatically demote the default target if the
compiler being used is too old to optimize for it. Updated docs to make
this behavior explicit. This avoids surprising the user if the default
compiler is older than the host architecture.
This commit adds unit tests to verify the semantics of target ranges and
target lists in constraints. The implementation to allow target ranges
and lists is minimal and doesn't add any new type. A more careful
refactor that takes into account the type system might be due later.

Add llnl.util.cpu_name, with initial support for detecting different
microarchitectures on Linux. This also adds preliminary changes for
compiler support and variants to control the optimizatoin levels by
target.
This does not yet include translations of targets to particular
compilers; that is left to another PR.

Move verbose messages to debug level
get_patchelf should return None for test platform as well because create_buildinfo invokes patchelf to get rpaths.
Update command-line (CLI) parsing to understand references to yaml
files that store Spack specs. Where a file reference is encountered,
the full Spec in the file will be read in. A file reference may
appear anywhere that a spec could appear before. For example, if you
write "spack spec -y openmpi > openmpi.yaml" you may then install the
spec using the yaml file by running "spack install ./openmpi.yaml";
you can also refer to dependencies in this way (e.g.
"spack install foo^./openmpi.yaml").
There are two requirements for file references:
* A file path entered on the CLI must include a "/" even if the file
exists in your current working directory. For example, if you
create an openmpi.yaml file as above and run
"spack install openmpi.yaml" from the same directory, it will
report an error.
* A file path entered on the CLI must end with ".yaml"
This commit adds error messages to clearly inform the user of both
violations.
* implicit_rpaths are now removed from compilers.yaml config and are always instantiated dynamically, this occurs one time in the build_environment module
* per-compiler list required libraries (e.g. libstdc++, libgfortran) and whitelist directories from rpaths including those libraries. Remove non-whitelisted implicit rpaths. Some libraries default for all compilers.
* reintroduce 'implicit_rpaths' as a config variable that can be used to disable Spack insertion of compiler RPATHs generated at build time.
Fixes#12732Fixes#12767c22a145 added automatic detection and RPATHing of compiler libraries
to Spack builds. However, in cases where the parsing/detection logic
fails this was terminating the build. This makes the compiler library
detection "best-effort" and reports an issue when the detection fails
rather than terminating the build.
This is similar to #10191. The Ubuntu package for clang 8.0.0 displays
a very unusual version string, and we need this new regex to detect it
as just 8.0.0
Unit test have been complemented by the output that was failing
detection.
- Fix trailing whitespace missed by the bug described in #12755.
- Fix other style issues that have crept in over time (this can happen
when flake8 adds new checks with new versions)
E501 (line too long) exemptions are probably our most common ones -- we
add them for directives, URLs, hashes, etc. in packages. But we
currently add them even when a line *doesn't* need them, which can mask
trailing whitespace errors.
This changes `spack flake8` so that it will only add E501 exemptions if
the line is *actually* too long.

mock_archive can now take multiple extension / tar option pairs (default matches old behavior).
url_fetch.test_fetch tests more archive types.
compression.EXTS split into EXTS and NOTAR_EXTS to avoid unwanted, non-meaningful combinatoric extensions such as .tar.tbz2.
- previously spec parsing didn't allow you to look up missing (but still
known) specs by hash
- This allows you to reference and potentially reinstall
force-uninstalled dependencies
- add testing for force uninstall and for reference by spec
- cmd/install tests now use mutable_database
* 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
`spec.prefix` reads from Spack's database, and if you do this with
multiple consecutive read transactions, it can take a long time. Or, at
least, you can see the paths get written out one by one.
This uses an outer read transaction to ensure that actual disk locks are
acquired only once for the whole `spack find` operation, and that each
transaction inside `spec.prefix` is an in-memory operation. This speeds
up `spack find -p` a lot.
Refactor `spack.cmd.display_specs()` and `spack find` so that any options
can be used together with -d. This cleans up the display logic
considerably, as there are no longer multiple "modes".
This is another machine-readable version of `spack find`. Supplying the
`--json` argument causes specs to be written out as json records,
easily filered with tools like jq.
e.g.:
$ spack find --json python | jq -C ".[] | { name, version } "
[
{
"name": "python",
"version": "2.7.16"
},
{
"name": "bzip2",
"version": "1.0.8"
}
]
- spack find --format allows you to supply a format string and have specs
output in a more machine-readable way, without dedcoration
e.g.:
spack find --format "{name}-{version}-{hash}"
autoconf-2.69-icynozk7ti6h4ezzgonqe6jgw5f3ulx4
automake-1.16.1-o5v3tc77kesgonxjbmeqlwfmb5qzj7zy
bzip2-1.0.6-syohzw57v2jfag5du2x4bowziw3m5p67
...
or:
spack find --format "{hash}"
icynozk7ti6h4ezzgonqe6jgw5f3ulx4
o5v3tc77kesgonxjbmeqlwfmb5qzj7zy
syohzw57v2jfag5du2x4bowziw3m5p67
...
This is intended to make it much easier to script with `spack find`
When Spack installs a package it writes the package.py file and
patches to a separate repository (which reflects the state of the
package at the time it was installed). Previously, Spack only wrote
patches that were used at installation time. This updates the
archiving step to include all patch files that are relevant to the
package (in case that repository is used in another context).
This commit removes redundant calls to `libtoolize` and `aclocal`.
Some configurations, such as a Spack user using macOS with a
Homebrew-installed `libtool` added to their `packages.yaml`, have
`autoreconf` and GNU libtoolize installed as `glibtoolize`, but not
`libtoolize`. While Spack installations of `libtool` built from source
would install `glibtoolize` and symlink `libtoolize` to `glibtoolize`,
an external installation of GNU libtoolize as `glibtoolize` will not
have such a symlink, and thus the call `m.libtoolize()` will throw an
error because `libtoolize` does not exist at the path referenced by
`m.libtoolize()` (i.e.,
`self.spec['libtool'].prefix.bin.join('libtoolize')).
However, on these same systems, `autoreconf` runs correctly, and calls
`glibtoolize` instead of `libtoolize`, when appropriate. Thus,
removing the call to `libtoolize` should resolve the error mentioned
above.
The redundant call to `aclocal` is also removed in this commit because
the maintainers of GNU Automake state that "`aclocal` is expected to
disappear" and suggest that downstream users never call `aclocal`
directly -- rather, they suggest calling `autoreconf` instead.

c9e214f updated template creation by passing **kwargs to package
template classes but the template classes were not updated to accept
them; this adds **kwargs to package template initializers where they
are needed.
Having a non-directory invisible file causes `spack find` to die. This
fixes the logic to ignore invalid module names but only warn if they're
visible.
```
NotADirectoryError: [Errno 20] Not a directory: '/spack/var/spack/repos/builtin/packages/.DS_Store/package.py'
```
This adds a special package type to Spack which is used to aggregate
a set of packages that a user might commonly install together; it
does not include any source code itself and does not require a
download URL like other Spack packages. It may include an 'install'
method to generate scripts, and Spack will run post-install hooks
(including module generation).
* Add new BundlePackage type
* Update the Xsdk package to be a BundlePackage and remove the
'install' method (previously it had a noop install method)
* "spack create --template" now takes "bundle" as an option
* Rename cmd_create_repo fixture to "mock_test_repo" and relocate it
to shared pytest fixtures
* Add unit tests for BundlePackage behavior
This allows "spack spec --yaml" to generate a spec YAML file that can
be used with "spack install -f". Before, this would fail in cases
where the spec had build dependencies.
* All fetch strategies now accept the Boolean version keyword option `no_cache` in order to allow per-version control of cache-ability.
* New git-specific version keyword option `get_full_repo` (Boolean). When true, disables the default `--depth 1` and `--single-branch` optimizations that are applied if supported by the git version and (in the former case) transport protocol.
* The try / catch blog attempting `--depth 1` and retrying on failure has been removed in favor of more accurately ascertaining when the `--depth` option should work based on git version and protocol choice. Any failure is now treated as a real problem, and the clone is only attempted once.
* Test improvements:
* `mock_git_repository.checks[type_of_test].args['git']` is now specified as the URL (with leading `file://`) in order to avoid complaints when using `--depth`.
* New type_of_test `tag-branch`.
* mock_git_repository now provides `git_exe`.
* Improved the action of the `git_version` fixture, which was previously hard-wired.
* New tests of `--single-branch` and `--depth 1` behavior.
* Add documentation of new options to the packaging guide.
- mkdirp now takes arguments to allow it to properly set permissions on created directories.
- Two arguments (group and mode) set permissions for the leaf directory.
- Intermediate directories can inherit permissions from either the topmost existing directory (the parent) or the leaf.
On machines where $TMP is owned by a gid with no name, this avoids the
following error when the default spack stage does not exist:
(spackbook):spack$ spack clean
==> Removing all temporary build stages
==> Error: 'getgrgid(): gid not found: 57095'
Spack needs to deal with gids directly unless users pass them in.
Compiler caching was using the `id()` function to refer to configuration dictionary objects. If these objects are garbage-collected, this can produce incorrect results (false positive cache hits). This change replaces `id()` with an object that keeps a reference to the config dictionary so that it is not garbage-collected.
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.
Fixes#12062406c791 addressed "spack module load" for upstream modules but not
the "spack module loads" command. This applies the same fixes from
406c791 to "spack module loads".
It's no longer possible to set compiler flags under as an entry under
"paths" in compilers.yaml; instead the user must list these under the
"flags" section. This updates the docs accordingly.
Spack stacks drop invalid dependencies applied to packages by a
spec_list matrix operation
Without this fix, Spack would raise an error if orthogonal dependency
constraints and non-dependency constraints were applied to the same
package by a matrix and the dependency constraint was invalid for
that package. This is an error, fixed by this PR.
An example failing configuration:
spack:
definitions:
- packages: [libelf, hdf5+mpi]
- compilers: ['%gcc']
- mpis: [^openmpi]
specs:
- matrix:
- $packages
- $compilers
- $mpis
5f74f22 enabled installing compilers for dependencies but not for the root package (and in particular not for DAGs which consist of one package)
this enables bootstrapping compilers for both types of DAGs
Using "compilers" with the "s" is an invalid config section and throws an error.

This updates the Spack QT package to enable building qt version 4 on
MacOS.
This includes the following changes to the qt package:
* add version 4.8.7
* add option to build with or without shared libs
* add options to disable tools, ssl, sql, and freetype support
* add qt4-tools patch when building qt@4+tools
* add option to build as a framework (only available on MacOS)
* replace qt4-el-capitan patch with qt4-mac patch (which includes the
edits from qt4-el-capitan)
* apply qt4-pcre-include-conflict.patch only for version 4.8.6
(rather than all 4.x versions)
* apply qt4-gcc-and-webkit.patch for 4.x versions before 4.8.7 and
create a separate qt4-gcc-and-webkit-487.patch for version 4.8.7
* update patch function for qt@4 on MacOS to update configure
variables relevant to Spack (e.g. PREFIX)
* add option to build freetype with Spack, as a vendored dependency
of QT, or not at all (default is to build with Spack)
This includes the following edits outside of the qt package:
* Update MacOS version utility function to return all parts of the
Mac version (rather than just the first two)
* gettext package: implement "libs"
* python package: add gettext as a dependency
* Raise an exception and exit with a meaningful message when binary path substitution fails.
* Skip binary text replacement with padding and issue a warning when the new install path is longer than the old install path.
- We don't currently make enough use of the maintainers field on
packages, though we could use it to assign reviews.
- add a command that allows maintainers to be queried
- can ask who is maintaining a package or packages
- can ask what packages users are maintaining
- can list all maintained or unmaintained packages
- add tests for the command
* Added a unit test reproducing the failure in 12085
* Fixed name clash in the 'from_environment_diff' function
The bug reported in #12085 stemmed from a name clash among variables,
introduced during the refactor in #10753 and not caught by unit tests
and reviews.
- Setting specs from lockfiles was not correctly stringifying concretized
user specs.
- Fix `_set_user_specs_from_lockfile`
- Add some validation code to `SpecList` constructor
Spack has evolved to have three types of hash functions, and it's
becoming hard to tell when each one is called. Whlie we aren't yet ready
to get rid of them, we can refactor them so that the code is clearer and
easier to track.
- Add a `hash_types` module with concise descriptors for hashes.
- Consolidate hashing logic in a private `Spec._spec_hash()` function.
- `dag_hash()`, `build_hash()`, and `full_hash()` all call `_spec_hash()`
- `to_node_dict()`, `to_dict()`, `to_yaml()` and `to_json()` now take a
`hash` parameter consistent with the one that `_spec_hash()` requires.

The database and mutable_database fixtures were installing and uninstalling the same specs multiple times to ensure the database for tests has the correct state.
This commit optimizes the procedure by caching the state in an external directory, and copying it in instead of going through the installation or uninstallation again.
The database fixture is meant not to be modified by tests. This commit enforces this invariant by making the database read-only before starting the test.
* Added missing db markers to tests
* Added test for uninstall_by_spec
* `database` fixture now returns a read-only database
* Tests that modify the DB now use `mutable_database` fixture
Summary:
- Allow multiple definitions of compiler in compilers.yaml (use first instance)
- Still print debug messages when there are duplicates, to assist users in finding this issue.
Merging configs from different scopes can result in multiple compiler being present in the same configuration list. Instead of raising when there are duplicates, take the one with highest precedence.
Print a debug message instead of raising, so that we can still diagnose this. We don't have a good way of warning the user about inconsistent configuration *in the same file* -- we'd need to dig into YAML file/line info for that.
- [x] Add shell tests to ensure that `spack env activate`, `spack env
deactivate`, and `despacktivate` continue to work.
- [x] Also ensure that activate and deactivate both work with `set -u`
* extends mkdirs with permissions for intermediate folders
Does not use os.makedirs mode parameter because its behavior is changed
with Python 3.7 (it ignores it for intermediate dirs), and moreover it
was not possible to set different modes for newly-created folders
and leaf folder.
reference:
- https://bugs.python.org/issue19930
- https://docs.python.org/3.7/library/os.html#os.makedirs
* comment mkdirp step easing code understanding
* revert mkdir to default for package metapath
since metapath is nested in package folder, there is no need
to specify permissions for intermediate folders because the prefix
already exists.
* comment create_install_directory package modes
Bug relates to the interplay between:
1. random dict orders in python 3.5
2. bugfix in initial implementation of stacks for `_concretize_dependencies`
when `self._dependencies` is empty
3. bug in coconcretization algorithm computation of split specs
Result was transient hang in coconcretization.
Fixed#3 (bug in coconcretization) to resolve.
- remove redundant code in Environment.__init__
- use socket.gethostname() instead of which('hostname')
- refactor updating SpecList references
- refactor 'specs' literals to a single variable for default list name
- use six.string_types for python 2/3 compatibility
* from_sourcing_file: fixed a bug + added a few ignored variables
closes#7536
Credits for this change goes to mgsternberg (original author of #7536)
The new variables being ignored are specific to Modules v4.
* Use Spack Executable in 'EnvironmentModifications.from_sourcing_file'
Using this class avoids duplicating lower level logic to decode
stdout and handle non-zero return codes
* Extracted a function that returns the environment after sourcing files
The logic in `EnvironmentModifications.from_sourcing_file` has been
simplified by extracting a function that returns a dictionary with the
environment one would have after sourcing the files passed as argument.
* Further refactoring of EnvironmentModifications.from_sourcing_file
Extracted a function that sanitizes a dictionary removing keys that are
blacklisted, but keeping those that are whitelisted. Blacklisting and
whitelisting can be done on literals or regex.
Extracted a new factory that creates an instance of
EnvironmentModifications from a diff of two environments.
* Added unit tests
* PS1 is blacklisted + more readable names for some variables
All documentation mentions that `build_jobs` is limited by the number of
cores available in the system. This is also enforced when setting it via
`--jobs`. However, when setting it via `config.yaml`, it can exceed the
number of cores available, making builds run out of memory.
This PR adds the ability to specify the auto-dispatch targets that can
be used by the Intel compilers. The `-ax` flag will be written to the
respective compiler configuration files. This ability is very handy when
wanting to build optimized builds for various architectures. This PR
does not set any optimization flags, however.
Fixes#3690Fixes#5637
Uninstalling dependents of a spec was relying on a traversal of the
parents done by inspecting spec._dependents. This is in turn a
DependencyMap that maps a package name to a single DependencySpec object
(an edge in the DAG) and cannot thus model the case where a spec has
multiple configurations of the same parent package installed (for
example if different versions of the same Python library depend on
the same Python installation).
This commit works around this issue by constructing the list of specs to
be uninstalled in an alternative way, and adds tests to verify the
behavior. The core issue with DependencyMap is not resolved here.
The default library search for a package checks the lib/ and lib64/
directories for libraries before the root prefix, in order to save
time when searching for libraries provided by externals (which e.g.
may have '/usr/' as their root).
This moves that logic into the "find_libraries" utility method so
packages implementing their own custom library search logic can
benefit from it.
This also updates packages which appear to be replicating this logic
exactly, replacing it with a single call to "find_libraries".
Fixes#11782
Spack was not properly resolving relative paths to absolute paths
when a relative path was passed to "spack compiler add [PATH]".
Now, if provided a relative path, the absolute path is written to
compilers.yaml rather than the relative path.
* Add template creation test
* Added --skip-editor option to "spack create": normally
"spack create" opens an editor for the user after generating a
package file; when the --skip-editor option is used, "spack create"
only generates the package file and does not open an editor
* Added --skip-editor option to bash completion
- Namepsaces were shown without dots after the new format strings were
added.
- Add a test for `spack find` to ensure that find -N shows the right
output.
Fixes#11781
* Rename build log to spack-build-log.txt
* Rename environment variables file to spack-build-env.txt
* The name of the log and env files is now the same during the build
and after the build completes
* Update packages which referred to the build log/env files
* For packages installed before this commit using older names for the
build and env files, search for the older names
- Fix a bug introdcued by removing parse_anonymous_spec()
- Conflicts' when specs are now *actually* anonymous, and the name of the
package is implicit, so we need to remember to add it back to error
messages.
- `parse_anonymous_spec()` is a vestige of the days when Spack didn't
support nameless specs. We don't need it anymore because now we can
write Spec() for a spec that will match anything, and satisfies()
semantics work properly for anonymous specs.
- Delete `parse_anonymous_spec()` and replace its uses with simple calls
to the Spec() constructor.
- make then handling of when='...' specs in directives more consistent.
- clean up Spec.__contains__()
- refactor directives and tests slightly to accommodate the change.
- CNL OS previously used the *Cray PE* version to determine the OS
version. Cray does not synchronize PE and CLE releases; you can run
CLE7 with PrgEnv 6 (and NERSC currently does).
- Fix Spack's OS detection by using the cle-release file to detect the OS
version. This file is updated with every CLE OS release.
- Add some tests for our parsing logic
Add an example of a 'modules:' entry for an external package in
packages.yaml. The 'External Packages' section of 'Build
Customization' mentions 'paths:' and 'modules:' and gives an
example of paths, but not modules.
Fixes#11816
Allow packages to refer to non-expanded downloads (e.g. a single
script) using Stage.archive_file. This addresses a regression from
#11688 and adds a unit test for it.
This change reverts to the previous behavior of only looking for pgcc
and friends, not pgcc-llvm and friends.
The llvm variant doesn't support all the same features as the
traditional variant of the pgi code generator; this change avoids
treating the llvm variant as a default pgi compiler.
This retains the changes in #10704 which accept the "LLVM" suffix of
the version string of the PGI compiler, which allows users to
explicitly add the llvm-pgi compiler if desired.
For resources, it is desirable to use the expanded archive name of
the resource as the name of the directory when adding it to the root
staging area.
#11528 established 'spack-src' as the universal directory where
source files are placed, which also affected the behavior of
resources managed with Stages.
This adds a new property ('srcdir') to Stage to remember the name of
the expanded source directory, and uses this as the default name when
placing a resource directory in the root staging area.
This also:
* Ensures that downloaded sources are archived using the expanded
archive name (otherwise Spack will not be able to determine the
original directory name when using a cached archive).
* Updates working_dir context manager to guarantee restoration of
original working directory when an exception occurs
* Adds a "temp_cwd" context manager which creates a temporary
directory and sets it as the working directory
The regression test for #11678 fails on at least some Mac OS systems
because they have a /usr/bin/gcc that is secretly clang.
This PR replaces the dependency on a system gcc executable with a
test-generated script that generates the expected output for the
compiler logic.
Some tests introduced in #11528 temporarily set the user's `config:build_stage`, which affected (or created) a config.yaml file in the user's `$HOME/.spack` directory that could leave entries behind if the tests fail.
This change ensures only temporary configuration files are used/affected by these tests.
The "spack location" command was previously untested. This also adds
a check to ensure that composite Stages can report whether they were
expanded (this property was previously only recorded in Stage but not
in CompositeStage).
DIYStage, used to treat a user-managed directory as a staging area,
should always be considered expanded (i.e. the source has been
decompressed if it was stored in an archive).
This also:
* Adds checks to ensure that the path used to instantiate a
DIYStage refers to an existing directory.
* Adds tests to check the behavior of DIYStage (including behavior
added here, but it was generally untested before).
#11528 updated Stage to always store a Package's source in a fixed
directory accessible via `Stage.source_path` This left behind a
number of packages which were expecting to access the source code
via `Stage.path`. This Updates those packages to use
`Stage.source_path` instead.
This also updates the name of the fixed directory: The original name
of the fixed directory was "src", so if an expanded archive created a
"src" directory, then users inspecting the directory structure could
see paths like "src/src" (which wasn't wrong but could be confusing).
Therefore this also updates the name of the fixed directory to
"spack-src".
Fixes#11678
`spack compiler find` was not searching `PATH` when provided with no
arguments. ea7910a updated the API for the search function and the
command logic did not update how it called this function. This also
adds a test to ensure that `spack compiler find` will collect
compilers from `PATH`.
"spack module tcl find -r <spec>" (and equivalents for other module
systems) was failing when a dependency was installed in an upstream
Spack instance. This updates the module index to handle locating
module files for upstream Spack installations (encapsulating the
logic in a new class called UpstreamModuleIndex); the updated index
handles the case where a Spack installation has multiple upstream
instances.
Note that if a module is not available locally but we are using the
local package, then we shouldn't use a module (i.e. if the package is
also installed upstream, and there is a module file for it, Spack
should not use that module). Likewise, if we are instance X using
upstreams Y and Z like X->Y->Z, and if we are using a package from
instance Y, then we should only use a module from instance Y. This
commit includes tests to check that this is handled properly.
Spack currently tries to unify everything in the DAG, but this is too strict for build dependencies, where it is fine to build a dependency with a tool that conflicts with a version fo that tool for a dependent's build.
To enable a workaround for conflicts among build dependencies, so that users can install in multiple steps to avoid these conflicts, make the following changes:
* Dont apply package dependency constraints for build deps of installed packages
* Avoid applying constraints for installed packages vs. concrete packages
* Mark all dependencies of installed packages as visited in normalization method
* don't remove dependency links for concrete specs in flat_dependencies
Also add tests:
* Update test to ensure that link dependencies of installed packages have constraints applied
* Add test to check for proper handling of transitive dependencies (which is currently not the case)
- spack.compilers.find_compilers now uses a multiprocess.pool.ThreadPool to execute
system commands for the detection of compiler versions.
- A few memoized functions have been introduced to avoid poking the filesystem multiple
times for the same results.
- Performance is much improved, and Spack no longer fork-bombs the system when doing a `compiler find`
- We use `spack list --foramt=html` now, as it is much faster and doesn't
make the docs build take forever.
- Remove `spack list --format=rst` as it is no longer used.
- `stage.source_path` was previously overloaded; it returned `None` if it
didn't exist and this was used by client code
- we want to be able to know the `source_path` before it's created
- make stage.source_path available before it exists.
- use a well-known stage source path name, `$stage_path/src` that is
available when `Stage` is instantiated but does not exist until it's
"expanded"
- client code can now use the variable before the stage is created.
- client code can test whether the tarball is expanded by using the new
`stage.expanded` property instead of testing whether `source_path` is
`None`
- add tests for the new source_path semantics
- make tty.msg, tty.info, etc. print the exception type and stringified
message if the message argument is an exception.
- simplify parts of the code that call tty.debug(str(e))
- add extra tty.debug statements in places where exceptions were
previously ignored
- `spack graph --static` (and `spack.graph.dot_graph`) now do the "right
thing" and print the possible dependency graph of provided packages.
- `spack graph --static` no longer concretizes specs, as it only relies
on class level metadata
- Previously the behavior was not consistent -- `spack graph --static`
would graph possible dependencies of concrete specs, but would only
include some of them. The new code properly pursues all possible
dependencies, and allows traversing by different dependency types.
- `spack dependencies` can now take a --deptype argument to only traverse
particular deptypes
- add a new "common" argument for deptype in spack.cmd.common.arguments
- Database.installed_relatives() can now also take a deptype argument
- this is used by `spack dependencies --installed`
- `PackageBase.possible_dependencies` now:
- accepts a deptype param that controls dependency types traversed
- returns a dict mapping possible depnames to their immediate possible
dependencies (this lets you build a graph easily)
- Add tests for PackageBaes
- The 'name' attribute for packages was being set in DirectiveMeta, which
wasn't consistent with other class properties (like fullname, etc.)
- Move it to be a class property of `PackageMeta`, and add the
corresponding property method wrapper on `PackageBase`
* add c99_flag, c11_flag to compiler class
* implement c99_flag, c11_flag for gcc
* implement c99_flag, c11_flag for arm
* implement c99_flag for cce
* implement c99_flag, c11_flag for clang
* implement c99_flag, c11_flag for intel
* implement c99_flag, c11_flag for xl
Previously, module files were not set with the same permissions as the package installation. For world-readable packages, this would not cause a problem. For group readable packages, it does:
```
packages:
mypackage:
permissions:
group: mygroup
read: group
write: group
```
In this case, the modulefile is unreadable by members of the group other than the one who installed it. Add logic to the modulefile writers to set the permissions based on the configuration in `packages.yaml`
* Build cache: relocate path to spack/bin/sbang in text files.
* Found in testing.
* update packaging test
* Make sbang replacement including #!/bin/bash. Add an additional spack prefix replacement to fix stage directory references.
* flake8
* Use buildinfo.get() so old buildcaches without buildinfo['spackprefix'] can be read.
* 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.
* The default is set to 16 or the number of available cores, whatever
is lowest.
* Updated docs to reflect the changes done to limit parallel builds
- `gettext_uuid=True` makes every commit update every .pot file in spack/localized-docs,
and speeds up the internationalized doc build slightly.
- Optimize for less repository churn, and use `python-levenshtein` to accelerate
the build instead.
- make all Spack paths relative to a `_spack_root` symlink, so that we
can easily relocate the docs build *outside* lib/spack/docs
- set some useful defaults for gettext translation variables in conf.py
- update `relativeinclude` and other references to the spack root in the
RST files to use _spack_root
- Add a `--update FILE` option to `spack list`
- Output is written to the file only if any package is newer than the file
- Simplify the code in docs/conf.py using this new option
The Spack documentation currently hard-codes some functionality in
`conf.py`, which makes the doc build less "pluggable" for things like
localized doc builds.
In particular, we unconditionally generate an index of commands and a
package list as part of the docs, but those should really only be done if
things are not up to date.
This commit does the following:
- Add `--header` option to `spack commands` so that it can do the work of
prepending text to its output.
- Add `--update FILE` option to `spack commands` that makes it generate a
new command index *only* if FILE is out of date w.r.t. commands in the
Spack source.
- Simplify code in `conf.py` to use these options and only update the
command index when needed.
This PR implements several refactors requested in #11373, specifically:
- Config scopes are used to handle builtin defaults, command line overrides
and package overrides (`parallel=False`)
- `Package.make_jobs` attribute has been removed; `make_jobs` remains
as a module-scope variable in the build environment.
- The use of the argument `-j` has been rationalized across commands
- move '-j'/'--jobs' argument into `spack.cmd.common.arguments`
- Add unit tests to check that setting parallel jobs works as expected
- add new test to ensure that build job setting is isolated to each build
- Fix packages that used `Package.make_jobs` (i.e. `bazel`)
* Add Fujitsu compiler to Spack.
* Fixes for flake8
* Chenges location of FCC to subdirectory called case-insensitive
* Add compiler tests for Fujitsu compiler
* Modify the logic of taking compiler version for new version of Fujitsu compiler
The regex used for finding the Cray OS version from the PrgEnv-cray
module was not exact and was at times pulling the version from other
PrgEnv modules. This updates the regular expression to be more exact.
Adds executable=/bin/bash into Popen. We discovered this bug while
working in a csh/tsch environment. By executing with /bin/bash we ensure
that the module command works.
#8612 added command extensions to Spack: a command implemented in a
separate directory. This improves the implementation by allowing
the command to import additional utility code stored within the
established directory structure for commands.
This also:
* Adds tests for command extensions
* Documents command extensions (including the expected directory
layout)
- `svn info` prints different results depending on the system locale
- in particular, Japanese output doesn't contain "Revision:"
- Change Spack code to use XML output instead of using the human output
Add fixes to support multiple installs and dependents using a subset
of IntelPackage functionality.
* Update IntelPackage to only return scalapack libraries if the root
spec depends on MPI: scalapack requires MPI to be mentioned as a
dependency in the DAG. Package builds using intel-mkl for its
blas/lapack implementations but not for scalapack were failing to
build.
Ideally it would be possible to ask if any of the packages in the
DAG are actually requesting the scalapack functionality provided by
the IntelPackage and only return scalapack libs in that case, but
that is not easily done at this time.
Fixes#11314Fixes#11289
* set HOME when the intel silent installer is run. This prevents the
installer from using the ~/intel directory (which can cause
conflicts for multiple installs of the same IntelPackage)
Fixes#9713
Use new `module` function instead of `get_module_cmd`
Previously, Spack relied on either examining the bash `module()` function or using the `which` command to find the underlying executable for modules. More complicated module systems do not allow for the sort of simple analysis we were doing (see #6451).
Spack now uses the `module` function directly and copies environment changes from the resulting subprocess back into Spack. This should provide a future-proof implementation for changes to the logic underlying the module system on various HPC systems.
Add two functions to the EnvironmentModifications object to help
users sanitize environment variables in their package definitions:
* deprioritize_system_paths: this keeps system paths in the
environment variable but moves them to the end.
* prune_duplicate_paths: remove any duplicate paths from the
variable
This includes testing for the new functions as well as for
(previously-untested) old convenience functions for environment
variable manipulation.
This also adds special handling for bash functions so they
will be defined when the exported environment file is sourced.
Fixes#11335
Update the Spack compiler wrappers to add the headerpad_max_install_names
linker flag on MacOS. This allows the install_name_tool to rewrite
the RPATH entry of the binary to be longer if needed. This is
primarily useful for creating and distributing binary caches of
packages (i.e. using the "spack buildcache" command); binary caches
created on MacOS before this commit may not successfully relocate
(if the target root path is larger).
* Added a function that concretizes specs together
* Specs concretized together are copied instead of being referenced
This makes the specs different objects and removes any reference to the
fake root package that is needed currently for concretization.
* Factored creating a repository for concretization into its own function
* Added a test on overlapping dependencies
* extend Version class so that 2.0 > 1.develop > 1.1
* add concretization tests, with preferences and preferred version.
* add master, head, trunk as develop-like versions, develop > master > head > trunk
* update documentation on version comparison
- `spack edit` previously used `spack.util.executable` `Executable` objects,
and didn't `exec` the editor like you'd expect it to
- This meant that Spack was still running while your editor was, and
stdout/stdin were being set up in weird ways
- e.g. on macOS, if you call `spack edit` with `EDITOR` set to the
builtin `emacs` command, then type `Ctrl-g`, the whole thing dies with
a `==> Error: Keyboard interrupt`
- Fix all this by changing spack.util.editor to use `os.execv` instead of
Spack's `Executable` object
Also add constructor to NoLibrariesError which can either take an
error message (like other SpackErrors) or a name and prefix (in
which case the error message is constructed).
PR #10758 made a slight change to find_versions_of_archive() which included
archive_url in the search process. While this fixed `spack create` and
`spack checksum` missing command-line arguments, it caused `spack
install` to prefer those URLs over those it found in the scrape process.
As a result, the package url was treated as a list_url causing all R
packages to stop fetching once the package was updated on CRAN.
This patch is more selective about including the archive_url in the
remote versions, explicitly overriding it with matching versions found
by the scraper.
f242f5f8 changed the format strings but maintained backwards
compatibility in all cases except one: The list of valid tokens for
the module naming schemes was not updated properly to contain both
the new and old styles for compilers and package names.
This PR re-adds the old tokens into the list of valid tokens.
#11152 added documentation for #8772 but some details were based on
an earlier implementation that had changed by the time #8772 was
merged. In particular, #11152 mentioned that upstream Spack instances
were configured in config.yaml, when in fact they should be placed in
a separate upstreams.yaml config file; this PR updates the
documentation accordingly.
fixes#11159
The 'namespace' argument to both Repo and RepoPath were used to set the
"super namespace". Currently it seems to be vestigial as the only
"super namespace" allowed for packages is 'spack.pkg' since 39c9bbf
* Make a separate CDash report for each package installed
Previously, we generated a single CDash report ("build") for the complete results
of running a `spack install` command. Now we create a separate CDash build for
each package that was installed.
This commit also changes some of the tests related to CDash reporting.
Now only one of the tests exercises the code path of uploading to a
(nonexistent) CDash server. The rest of the related tests write their reports
to disk without trying to upload them.
* Don't report errors to CDash for successful packages
Convert errors detected by our log scraper into warnings when the package
being installed reports that it was successful.
* Report a maximum of 50 errors/warnings to CDash
This is in line with what CTest does. The idea is that if you have more than
50 errors/warnings you probably aren't going to read through them all anyway.
This change reduces the amount of data that we need to transfer and store.
* Update spec format to simpler syntax, maintain backwards compatibility
* Switch to new spec.format method throughout internals
* update package files for new format strings
* documentation and minor code cleanup. removed nonsensical variant sigils
Fixes#11070#11010
Spack attempts to intercede on behalf of all compiler invocations for
a build. This involves adding its wrappers to PATH. Cray systems
include a "ftn" executable and Spack was only redirecting this call
when the Spec was built with cce. This updates the compiler wrappers
to add "ftn" in all cases.
The default (implied) behavior for all environments, as of ea1de6b,
is that an environment will maintain a view in a location of its
choosing. ea1de6b explicitly recorded all three possible states of
maintaining a view:
1. Maintain a view, and let the environment decide where to put it
(default)
2. Maintain a view, and let the user decide
3. Don't maintain a view
This commit updates the config writer so that for case [1], nothing
will be written to the config.yaml. This will not change any existing
behavior, it just serves to keep the config more compact.
Compilers are treated separately from other dependencies in Spack.
#10761 added the option to automatically install compilers when a
package specifies using a compiler that is not available in Spack.
However, this did not work correctly for dependency packages (it
would only build a compiler for the root of an install DAG). This
commit enables the building of compilers for dependency packages.
Environments are nowm by default, created with views. When activated, if an environment includes a view, this view will be added to `PATH`, `CPATH`, and other shell variables to expose the Spack environment in the user's shell.
Example:
```
spack env create e1 #by default this will maintain a view in the directory Spack maintains for the env
spack env create e1 --with-view=/abs/path/to/anywhere
spack env create e1 --without-view
```
The `spack.yaml` manifest file now looks like this:
```
spack:
specs:
- python
view: true #or false, or a string
```
These commands can be used to control the view configuration for the active environment, without hand-editing the `spack.yaml` file:
```
spack env view enable
spack env view envable /abs/path/to/anywhere
spack env view disable
```
Views are automatically updated when specs are installed to an environment. A view only maintains one copy of any package. An environment may refer to a package multiple times, in particular if it appears as a dependency. This PR establishes a prioritization for which environment specs are added to views: a spec has higher priority if it was concretized first. This does not necessarily exactly match the order in which specs were added, for example, given `X->Z` and `Y->Z'`:
```
spack env activate e1
spack add X
spack install Y # immediately concretizes and installs Y and Z'
spack install # concretizes X and Z
```
In this case `Z'` will be favored over `Z`.
Specs in the environment must be concrete and installed to be added to the view, so there is another minor ordering effect: by default the view maintained for the environment ignores file conflicts between packages. If packages are not installed in order, and there are file conflicts, then the version chosen depends on the order.
Both ordering issues are avoided if `spack install`/`spack add` and `spack install <spec>` are not mixed.
When providing a track, the cdash reporter will format the stamp
itself, as it has always done, and register the build during the
package installation process. When providing a stamp, it should
first be formatted as cdash expects, and then cdash will be sure
to report results to same build id which was registered manually
elsewhere.
* Update Spec.prefix to have special case for 'None' in database path; regression test
* Update in database reader rather than spec
* Change assertion to conditional + raise
* Added test for concrete check in Spec.prefix
The module_parsing test checks whether the module function is available
by looking for the string 'not found'. If the user has set a different
locale, the test can assume that the module function is available when
it actually is not.
* Split get_compiler_version into two functions:
get_compiler_version_output runs the compiler with the relevant
option to print the version; extract_version_from_output determines
the version by examining this output. This makes it easier to test
the customized version detection for each compiler. Users can
customize this by overriding the following:
* version_argument: this is the argument that tells the compiler to
print its version. It assumes that the compiler will report its
version if invoked with a single option (like "--version")
* version_regex: the regular expression used to extract the version
from the compiler argument. This assumes that a regular
expression is sufficient to extract the version, and that the
version can be extracted from a single capture group (Spack uses
the first capture group)
* default_version: allows you to completely override all version
detection logic
* get_compiler_version_output: if getting the compiler to report
its version is more complex than invoking it with a single arg
* extract_version_from_output: if it is difficult to define a regex
that can be used to extract the version from the output
* Added tests for version detection of most compilers
* Removed redundant code from xl_r compiler class (by inheriting
from xl compiler definition)
Replace the original implementation of the "memoized" decorator with
an implementation that exposes the docstring and arguments of the
wrapped function. This is achieved using functools.wraps.
This provides a mechanism to implement a new Spack command in a
separate directory, and with a small configuration change point Spack
to the new command.
To register the command, the directory must be added to the
"extensions" section of config.yaml. The command directory name must
have the prefix "spack-", and have the following layout:
spack-X/
pytest.ini #optional, for testing
X/
cmd/
name-of-command1.py
name-of-command2.py
...
tests/ #optional
conftest.py
test_name-of-command1.py
templates/ #optional jinja templates, if needed
And in config.yaml:
config:
extensions:
- /path/to/spack-X
If the extension includes tests, you can run them via spack by adding
the --extension option, like "spack test --extension=X"
* initial work to make use of an 'upstream' spack installation: this uses the DB of the upstream installation to check if a package is installed
* need to query upstream dbs when adding new record to local db
* prevent reindexing upstream DBs
* set prefix on specs read from DB based on path stored in install record
* check that Spack does not install packages that are recorded as installed in an upstream db
* externals do not add their path to install records - need to use 'external_path' to get path of upstream externals
* views need to check for upstream installations when linking metadata
* package and spec now calculate upstream installation properties on-demand themselves rather than depending on concretization to set these properties up-front. The added tests for upstream installations don't work with this new strategy so they need to be updated
* only refresh modules for local specs (not those in upstream packages); optionally generate local module files for packages installed upstream
* when a user tries to locate a module file for a package installed upstream, tell them to use the upstream spack instance to locate it
* support recursive upstream databases (allow upstream databases to use their own upstream databases)
* separate upstream config into separate file with its own schema; each entry now also includes a name
* metadata_dir is no longer customizable on a per-instance basis for YamlDirectoryLayout
* treat metadata_dir as an instance variable but dont set it from kwargs; this follows several other hardcoded variables which must be consistent between upstream and downstream DBs. Also update DirectoryLayout.metadata_path to work entirely with Spec.prefix, since Spec.prefix is set from the DB when available (so metadata_path was duplicating that logic)
Change the location of the CMake build area from the staged source
directory to the stage base directory.
This change allows CMake packages to refer to the build directory in
setup_environment (e.g. if tests need to have a directory in PATH):
Staging happens after the call to setup_environment(), and if the
stage area does not exist, then spec.stage.source_path returns None.
To accommodate this change, archived files (like config.log for
Autotools packages) are archived relative to the stage base directory
rather than the expanded source directory.
Other packages (those not using CMake) will still use the staged
source directory as the default working directory for builds (and
will still be unable to reference this directory in
setup_environment())
When multiple instances of environment-modules were installed with
different architectures, Spack was not retrieving the installation
appropriate for the current architecture when finding the module
prefix.
* Fixed some issues with CUDA-Intel compiler conflicts.
* Comment about expressing CUDA-compiler conflicts.
* More precise conflicts and also add support for Intel 19.0
If the user has set the environment variable VISUAL, it will be used
in preference to EDITOR for all Spack editing activities. If VISUAL
is not set or fails (perhaps due to a lack of graphical editing
capabilities),EDITOR will be used instead. We fall back to one of
several common editors if neither bears fruit.
This feature has been tailored to:
* Provide identical behavior to the previous implementation in the
case that VISUAL is not set.
* Not require any change to code utilizing the editor feature.
* Follow usual UNIX behavior concerning VISUAL and EDITOR.
* Fix clearing EnvironmentModifications with python2
* Add EnvironmentModifications::clear unit test
Use re-assignment rather than del to clear array
* Fix flake issues
Fixes#10191
* Add more regular expressions to detect clang versions that were
not being picked up
* Add a test for parsing versions from the output of Clang (this
does not run Clang, but rather uses example outputs from Clang)
* Separate Clang version parsing into its own method (to make it
easier to test)
Currently, only C headers are considered, causing build failures for
packages depending on, e.g., netcdf-fortran and xerces-c. Additionally,
the regex used to look for the include path component did not consider
word boundaries, causing false matches.
* Create option to build missing compilers and add them to config before installing packages that use them
* Clean up kwarg passing for do_install, put compiler bootstrapping in separate method
* Rework of buildcache creation and install prefix checking using the functions introduced in
https://github.com/spack/spack/pull/9199
Instead of replacing rpaths with placeholder and then checking strings, make use of the functions
relocate.is_recocatable and relocate.is_file_relocatable to decide if a package needs the allow-root option.
This fixes a problem where the placeholder path was not in the first rpath entry. This was seen in c++ libraries and binaries because the compiler was outside the spack install base path and always appears first in the rpath.
Instead of checking the first rpath entry, all rpaths have the placeholder path and the old install path (if it exists) replaced with the new install path.
* flake8
* Added the `spack buildcache preview` sub-command
This is similar to `spack spec -I` but highlights which nodes in a DAG
are relocatable and which are not.
spec.tree has been generalized a little to accept a status function,
instead of always showing the install status
The current implementation works only for ELF, and needs to be
generalized to other platforms.
* Added a test to check if an executable is relocatable or not
This test requires a few commands to be present in the environment.
Currently it will run only under python 3.7 (which uses Xenial instead
of Trusty).
* Added tests for the 'buildcache preview' command.
* Fixed codebase after rebase
* Fixed the list of apt addons for Python 3.7 in travis.yaml
* Only check ELF executables and shared libraries. Skip checking virtual or external packages. (#229)
* Fixed flake8 issues
* Add handling for macOS mach binaries (#231)
