- 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

- list or enumeration should not be indented
- use console instead of bash or csh in things that are not scripts
- other typos
* module file support: fixed other issues found by @adamjstewart
- tables should not be indented
- substitute lines with pyobject to import an entire function
- get help output running commands
- typos
* module file support: fixes according to review comments
- @citibeth moved `spack module loads` after `spack load`
- @glennpj tried to clarify installation table + changes to language
- @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()

* 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
