* Porting: substitute nose with ytest
This huge commit substitutes nose with pytest as a testing system. Things done here:
* deleted external/nose as it is no longer used
* moved mock resources in their own directory 'test/mock/'
* ported two tests (cmd/find, build_system) to pytest native syntax as an example
* build_environment, log: used monkeypatch instead of try/catch
* moved global mocking of fetch_cache to an auto-used fixture
* moved global mocking from test/__init__.py to conftest.py
* made `spack test` a wrapper around pytest
* run-unit-tests: avoid running python 2.6 tests under coverage to speed them up
* use `pytest --cov` instead of coverage run to cut down testing time
* mock/packages_test: moved mock yaml configuration to files instead of leaving it in the code as string literals
* concretize.py: ported tests to native pytest, reverted multiprocessing in pytest.ini as it was creating the wrong report for coveralls
* conftest.py, fixtures: added docstrings
* concretize_preferences.py: uses fixtures instead of subclassing MockPackagesTest
* directory_layout.py: uses fixtures instead of subclassing MockPackagesTest
* install.py: uses fixtures instead of subclassing MockPackagesTest
* optional_deps.py: uses fixtures instead of subclassing MockPackagesTest

* pytest: added docstrings to all the fixtures
* pytest: final cleanup
* build_system_guess.py: fixed naming and docstrings as suggested by @scheibelp
* spec_syntax.py: added expected failure on parsing multiple specs closes#1976
* Add pytest and pytest-cov to Spack externals.
* Make `spack flake8` ignore externals.
* run-unit-tests runs spack test and not pytest.
* Remove all the special stuff for `spack test`
- Remove `conftest.py` magic and all the special case stuff in `bin/spack`
- Spack commands can optionally take unknown arguments, if they want to
handle them.
- `spack test` is now a command like the others.
- `spack test` now just delegates its arguments to `pytest`, but it does
it by receiving unknown arguments and NOT taking an explicit
help argument.
* Fix error in fixtures.
* Improve `spack test` command a bit.
- Now supports an approximation of the old simple interface
- Also supports full pytest options if you want them.
* Use external coverage instead of pytest-cov
* Make coverage use parallel-mode.
* change __init__.py docs to include pytest
* inheritance of directives: using meta-classes to inject attributes coming from directives into packages + lazy directives
* _dep_types -> dependency_types
* using a meta-class to inject directives into packages
* directives are lazy
fixes#2466
* directives.py: allows for multiple inheritance. Added blank lines as suggested by @tgamblin
* directives.py: added a test for simple inheritance of directives
* Minor improvement requested by @tgamblin
CMakePackage: importing names from spack.directives
directives: wrap __new__ to respect pep8
* Refactoring requested by @tgamblin
directives: removed global variables in favor of class variables. Simplified the interface for directives (they return a callable on a package or a list of them).
* Ensure that every package has a license
Also fixes URLs with http://http:// doubled.
This is a continuation of #2656.
* Add license to every file in Spack
* Make sure Todd is the author of all packages
* Fix flake8 tests
* Don't license external Sphinx docs
* Don't display licenses in tutorial example packages
Also fixes typos and converts command-line examples
from tcsh to bash, which is more common
That's because in set_build_environment_variables()
the funciton filter_system_paths() is actually applied to
package prefixes, and not to prefix/lib or prefix/include.
The primary goal of #2292 was to use the frontend compiler to make
build dependencies like cmake on HPC platforms. It turns out that
while this works in some cases, it did not handle cases where a
package was a link dependency of the root and of a build dependency
(and could produce incorrect concretizations which would not build).
* Better output for disambiguate_specs()
* Fix wrong exception name.
* Fix satsifies(): concrete specs require matching by hash.
- Fixes uninstall by hash and other places where we need to match a
specific spec.
- Fix an error in provider_index (satisfies() call was backwards)
- Fix an error in satisfies_dependencies(): checks were too shallow.
* Fix default args in Spec.tree()
* Move installed_dependents() to DB to avoid unknown package error.
* Make `spack find` and `sapck.store.db.query()` faster for hashes.
* Add a test to ensure satisfies() respects concrete Specs' hashes.
* Customization for make targets in build and test phases for AutotoolsPackage
* Updated Blitz++ to use customized make build and test targets
* Removed flake8 error
* Removed make test customization, added make install customization, need to figure out issues with multiple make targets
* Changed build_targets and install_targets to normal attributes
* MakefilePackage: changed build_args and install_args for consistency with #2464
openblas: derives from MakefilePackage
* MakefilePackage: changed default edit behavior
* Better cxx11/14 flags for GNU/Clang/Intel
- GCC 4.8 only supports -std=c++1y for C++14
- Use CMake's rules for AppleClang to set cxx11 and cxx14 flags based on
Apple Xcode/LLVM version
- Use CMake's rules for Intel to add support for cxx14 flags based on
Intel version.
* Add cxx17_flag property
Implement property in compiler for c++17 as per those for c++11/14.
Add concrete support for GNU/Clang:
- Return -std=c++1z for GCC 5 and above per GCC documentation
- Return -std=c++1z for Clang 3.5 and above per Clang documentation
- Return -std=c++1z for Apple LLVM 6.1 and above per CMake's rules
* Update `spack setup` and `spack graph` to be consistent with c557e765 and 9347f869. Fixes#2316.
* Added another "fix" necessary to make `spack setup` work.
* Added another "fix" necessary to make `spack setup` work. (reverted from commit 7f0d3ecb38c97ec00491d7cd66b4266e3018b1ca)
* Add documentation for repositories and namespaces.
* Update and extend repository documentation per review.
- Also add `-N` argument for `spack spec`
The advanced [Uninstalling Packages](spack.readthedocs.io/en/latest/tutorial_sc16_spack_basics.html#uninstalling-packages) via hash has a couple missing `.. code-block:: console` directives ;)
I have no idea what branch to direct this to though...
* clang: do xcode mockup iff requested by a package
* add a note
* add pkg to setup_custom_environment() and decide whether or not to use mockup XCode there based on the package
* Make targets an attribute of compilers, similar to OS. Allows users to use `spack compiler find` to add compilers for the same platform/os but different targets when spack is installed on a file system mounted on machines with different targets.
* Changed get_compilers() method to treat old compilers with no target as target='any'
* flake8 changes
* Address change requests for comments/code clarity
Fixes#2306
Any dependency explicitly mentioned in a spec string ended up with the
build and link deptypes unconditionally. This fixes dependency
resolution to ensure that packages which are mentioned in the spec
string have their deptypes determined by the dependency information
in the package.py files. For example if a package has cmake as a build
dependency, and cmake is mentioned as a dependency in the spec string
for the package, then it ends up with just the build deptype.
Packages built targeting a backend may depend on packages like cmake
which can be built against the frontend. With this commit, any build
dependency or child of a build dependency will target the frontend by
default. In compiler concretization when packages copy compilers from
nearby packages, build dependencies use compiler information from
other build dependencies, and link dependencies avoid using compiler
information from build dependencies.
* Use JSON for the database instead of YAML.
- JSON is much faster than YAML *and* can preserve ordered keys.
- 170x+ faster than Python YAML when using unordered dicts
- 55x faster than Python YAML (both using OrderedDicts)
- 8x faster than C YAML (with OrderedDicts)
- JSON is built into Python, unlike C YAML, so doesn't add a dependency.
- Don't need human readability for the package database.
- JSON requires no major changes to the code -- same object model as YAML.
- add to_json, from_json methods to spec.
* Add tests to ensure JSON and YAML don't need to be ordered in DB.
* Write index.json first time it's not found instead of requiring reindex.
* flake8 bug.
* Added some notes about how multiarch detection could be fixed.
* Implemented a preliminary version of the "spack.spec.ArchSpec" class.
* Updated the "spack.spec.Spec" class to use "ArchSpec" instead of "Arch".
* Fixed a number of small bugs in the "spack.spec.ArchSpec" class.
* Fixed the 'Concretizer.concretize_architecture' method so that it uses the new architecture specs.
* Updated the package class to properly use arch specs.
Removed a number of unused architecture functions.
* Fixed up a number of bugs that were causing the regression tests to fail.
Added a couple of additional regression tests related to architecture parsing/specification.
Fixed a few bugs with setting reserved os/target values on "ArchSpec" objects.
Removed a number of unnecessary functions in the "spack.architecture" and "spack.concretize" modules.
* Fixed a few bugs with reading architecture information from specs.
Updated the tests to use a uniform architecture to improve reliability.
Fixed a few minor style issues.
* Adapted the compiler component of Spack to use arch specs.
* Implemented more test cases for the extended architecture spec features.
Improved error detection for multiple arch components in a spec.
* Fix for backwards compatibility with v0.8 and prior
* Changed os to unknown for compatibility specs
* Use `spack09` instead of `spackcompat` for the platform of old specs.
Different compilers have different flags for PIC (position-independent
code). This patch provides a common ground to accessing it inside specs.
See discussions in #508 and #2373. This patch does not address the issue
of mixed compilers as mentioned in #508.
Package provides a 'list_url' attribute which may be searched to find
download links. #1822 created a slowdown for all tests by always
searching this URL. This reenables dynamic search only in cases where
all other fetchers fail. This also only enables dynamic search when
'mirror_only' is set to false.
The option -s now causes file and line number information to be printed
along with any invocation of msg, info, etc...
This will greatly ease debugging.
- Seems like older git versions won't be able to clone an LFS repo.
- Reverting to an external link for the slides to avoid storing an 8MB
file in the repo and to avoid using git LFS.
* Allow compiler wrapper to modify environment
This adds the ability to set environment variables in the compiler
wrappers. These are specified as part of the compilers.yaml config.
The user may also specify RPATHs in compilers.yaml that should be
added.
* Minor doc tweak
* Waste less space when fetching cached archives, simplify fetch messages.
- Just symlink cached files into the stage instead of copying them with curl.
- Don't copy linked files back into the cache when done fetching.
* Fixes for review.
* more updates
* last update
Not the desired eventual behavior, but cflag subset matching is not currently working for anonymous specs and this provides a temporary solution by restricting the feature until it is fixed.
* Wordsmithing/minor-edits to module tutorial
A small set of wordsmithing, spell checking and minor edits to the fancy
new modules tutorial!
* Fix typo (sneaky z key...)
* Fix "S:" and "manual<" typos
Some packages which include resources fetched from source control
repositories terminated package installs because they failed to
archive; specifically, this included all SCM resources which identify
a specific state of the repo - for example a revision in svn or a
tag/revision in git. This is because the resource stage creation
logic did not choose an appropriate archive name for these kinds of
resources.
* module files tutorial : first complete draft

- typos from @adamjstewart
- rewording of a few sentences
* module file tutorial : first batch of corrections
- emphasized lines in yaml files
* module file tutorial : fixes according to @citibeth and @adamjstewart reviews
- used long format for command options
- reworded unclear sentence on tokes
- reworked table in reference manual to make it clearer
* module file tutorial : implemented corrections collected on site from @schlyfts
* module file tutorial : removed comment (@hartzell suggestion)
* Add options for hashes, tree depth, and YAML to `spack spec`.
- Can now display hashes with `spack spec`, like `spack find`.
- Removed the old "ids" argument to `spack spec` (which
printed numerical values)b
- Can output YAML spec from `spack spec` with `-y`
- Can control depth of DAG traversal with --cover=[nodes|edges|paths]
- Can print install status (installed, missing, not installed) with -I
* Don't use YAML aliases in specs.
- Force Spack's YAML dumper to ignore aliases.
- aliases cause non-canonical YAML to be used in DAG hash, and result in
redundant hashes.
- add a test to ensure this behavior stays
* spack install: forward sys.stdin to child processes fixes#2140
- [ ] redirection process is spawned in __enter__ instead of __init__
- [ ] sys.stdin is forwarded to child processes
* log: wrapped __init__ definition
1) list gfortran as a fc and f77 compiler that can work with clang
2) allow compatible gfortran to ./spack compiler find with clang by matching version numbers
This is based on the discussions in
https://github.com/LLNL/spack/issues/237https://github.com/dealii/dealii/wiki/deal.II-in-Spack#mixing-gcc-and-clang-on-osx
This is not a long term solution but something to get us through the next months until the compiler
infrastructure is reworked to allow mixing and matching for C/C++ and Fortran compilers

- Detailed debug information is now handed back to the parent process
from builds, for *any* type of exception.
- previously this only worked for Spack ProcessErrors, but now it works
for any type of error raised in a child.
- Spack will print an error message and source code context for build
errors by default.
- It will print a stack trace when using `spack -d`, even when the error
occurred in the child process.
- Ported old run-flake8-tests qa script to `spack flake8` command.
- New command does not modify files in the source tree
- Copies files to a temp stage modifies them there, and runs tests.
- Updated docs and `run-flake8-tests` script to call `spack flake8`.
- generalized and fixed to work with any key in YAML file
- simplified schema writing, as well
- add more unit tests for the config system
- Rename test/yaml.py to test/spack_yaml.py
- Add test/yaml.pyc to ignored pyc files.
- Added a schema for config.yaml
- Moved install tree configuration to config.yaml
- Moved etc/spack/install.yaml to etc/spack/defaults/config.yaml
- renamed install_area to "store", to use a term in common with guix/nix.
- in `config.yaml` file, it's called the `install_tree` to be more
intuitive to users.
- `install_tree` might've worked in the code, but `install_tree` is
already a global function in the spack namespace, from
llnl.util.filesystem.
Merge #2030 added a cyclic dependency between the Cray platform needing
to read a `targets.yaml` config file and `config.py` needing to get the
platform names.
This commit removes the cyclic dependency in favor of the more general
config scheme. It also removes the now functionless `targets.yaml`
config file. This breaks 'frontend' targets on the Cray platform but
all architecture targets, including the frontend, that are provided by
CrayPE are added to the Platform anyway so users can be explicit about
the architecture targeted by the Cray compiler wrappers:
```
spack spec libelf arch=cray-CNL-frontend
```
becomes
```
spack spec libelf arch=cray-CNL-mc8 # on an XK7 or
spack spec libelf arch=cray-CNL-sandybridge # on an older XC30, etc..
```
The only way the 'frontend' target can be defined after this commit is
through target environment variables.
* module file support: major rework of docs

- @tgamblin Removed top level section and moved the whole thing into the reference manual
* module file support: moved directive before spack module loads
External packages do not have an spec.yaml file so don't check for it.
Without this change any time a package depends on an external package
when the new package is installed you will get the error
Install prefix exists but contains no spec.yaml
This problem has also haunted me since I started using Spack since PETSc
depends on Python and I used an external python but fortunately it
was relatively easy to debug once I could reproduce it at will.

This replaces a custom token-based substitution format with calls to
Spec.format in modules.py
This also resolves a couple issues:
- LmodModules set configuration globally instead of in its initializer
which meant test-specific configuration was not applied
- Added support for setting hash_length=0 for LmodModules. This only
affects the module filename and not the directory names for the
hierarchy tokens in the path. This includes an additional unit test.
* add filter_system_paths()
* filter system paths in set_build_environment_variables()
* two function: lib/inc + bin
* reverse order in bin
* fix order
* minor
* improvements of the code
* more cleanup
* alternative solution for filter_bins
* fiddle base alalazo's approach
* minor
* minor
* Fixed a bug causing config-specified compiler flags to be ignored.
Updated the compiler config so all flags are in a separate section.
* Updated the documentation for the `compilers.yaml` file spec.
* Implemented basic testing for the 'flags' section of compiler config.
* Fixed a few minor problems with the manual compiler config documentation.
* Add new version property to handle joined version numbers
* Add unit test for new joined property
* Add documentation on version.up_to() and version.joined
* Removes the extra argument from Package.do_install while maintaining the changes in behavior pulled in #1603
* install : removed -i and -d shorthands (breaks backward compatibility)
* Change ':' to ','
* build_environment: allow compilers to set up an environment
* clang: mock up a toolchain directory for xcode
Some projects ignore CC and CXX flags and instead use xcode to find the
toolchain. Clang on Apple should set up the environment properly.
Arguably, every compiler could do this on Apple, but let's see how this
works out just for AppleClang for now.
The Documentation directory is ~1.7G and the excluded platforms add up
to about 7G. Ignoring swift saves another 500M. The resulting Xcode.app
copy is in the 2G range.
* compiler: set member variables early
This is required so that later methods can query things such as the
version of the compiler.
* compiler: support finding the real path of the compiler
On Apple, the /usr/bin compilers are actually wrapping tools themselves
which query xcrun for the currently selected Xcode installation. Pierce
this veil and get the real, full path the to underlying compilers
instead.
* icu4c: install with rpath
On macOS, icu installs with a library ID of the library name. Enabling
rpath makes its ID its full installed path which lets Qt5 link against
it successfully.
* qt: no -no-gtkstyle flag on Qt5 on macOS
* Rebase and merging using platform.system
Rebasing and merging using platform.system instead of uname -a.
* Add missing import platform statement
* Remove subprocess import
Remove ununsed import subprocess to make changes flak8 compliant
- Locks now use fcntl range locks on a single file.
How it works for prefixes:
- Each lock is a byte range lock on the nth byte of a file.
- The lock file is ``spack.installed_db.prefix_lock`` -- the DB tells us
what to call it and it lives alongside the install DB. n is the
sys.maxsize-bit prefix of the DAG hash.
For stages, we take the sha1 of the stage name and use that to select a
byte to lock.
With 100 concurrent builds, the likelihood of a false lock collision is
~5.36e-16, so this scheme should retain more than sufficient paralellism
(with no chance of false negatives), and get us reader-writer lock
semantics with a single file, so no need to clean up lots of lock files.
- Closing and re-opening to upgrade to write will lose all existing read
locks on this process.
- If we didn't allow ranges, sleeping until no reads would work.
- With ranges, we may never be able to take some legal write locks
without invalidating all reads. e.g., if a write lock has distinct
range from all reads, it should just work, but we'd have to close the
file, reopen, and re-take reads.
- It's easier to just check whether the file is writable in the first
place and open for writing from the start.
- Lock now only opens files read-only if we *can't* write them.
A use case where the previous approach was failing is :
- more than one spack process running on compute nodes
- stage directory is a link to fast LOCAL storage
In this case the processes may try to unlink something that is "dead" for them, but actually used by other processes on storage they cannot see.
* This fixes a bug in concretization. Before the recent change to the
algorithm, the intent was that the @develop version, although
"greater" than numberic versions, is never preferred BY DEFAULT over
numeric versions.
To test this... suppose you have a package with no `preferred=True` in
it, and nothing in `packages.yaml`, but with a `develop` version. For
the sake of this example, I've hacked my `python/package.py` to work
this way.
Without bugfix (WRONG: user should never get develop by default):
```
python@develop%clang@7.3.0-apple~tk~ucs4 arch=darwin-elcapitan-x86_64
...
```
With bugfix (RIGHT: largest numeric version selected):
```
python@3.5.2%clang@7.3.0-apple~tk~ucs4 arch=darwin-elcapitan-x86_64
...
```
* Documented version selection in concretization algo.
* Fix typos
* flake8
* Fix various documentation bugs
* Keep long option names, but don't include in Command Index
* Use long option name
* Explicitly designate sections to be listed in the Command Index
* Consistent menu bar titles
Input/output/error streams not directed to None or 'str' were not being closed
because `close()` method was being called on the argument value (a string type)
instead of the open file descriptor object.
* Fix bug in handling of precedence of preferred=True vs. versions given in packages.yaml (#1556)
* Standardized comparison of versions: numeric versions are always greater than non-numeric versions; and non-numeric versions are sorted alphabetically.
This is
a) simple
b) ensures that non-numeric versions (such as 'develop') in package.py are not chosen ahead of numeric versions, when nothing is specified in packages.yaml
Fixes Issue #1557
* Removed debugging output
* Fix variable shadowing bug
* Ensure develop < numeric version.
* Bug fix.
* Passes all unit tests in versions.py
* flake8 fixes
* flake8 fixes
* Changed type test to be more correct.
See http://stackoverflow.com/questions/8203336/difference-between-int-and-numbers-integral-in-python
This closes#1757 which provides an example of a url scheme where the
version appears after the extension. Instead of extending the parsing
logic to handle this case, this commit allows the user to specify
their extension type. This helps Spack choose the appropriate
decompressor and mirror archive filename.
* Transferred pending changes from efischer/develop
* 1. Rewrite of "Getting Started": everything you need to set up Spack, even on old/ornery systems. This is not a reference manual section; items covered here are covered more systematically elsewhere in the manual. Some sections were moved here from elsewhere.
