2017-09-07dump environment in sourceable form (#5301)Rob Latham1-1/+1
First, quote the environment variable values. Second, export the variables. sorry, this is bourn-shell syntax. Happy to consider a shell-independent way to do this, but spack is already using sh-like "env=value"

2017-09-05Added support for querying by tags (#4786)Massimiliano Culpo9-127/+518
* Added support to query packages by tags. - The querying commands `spack list`, `spack find` and `spack info` have been modified to support querying by tags. Tests have been added to check that the feature is working correctly under what should be the most frequent use cases. * Refactored Repo class to make insertion of new file caches easier. - Added the class FastPackageChecker. This class is a Mapping from package names to stat info, that gets memoized for faster access. - Extracted the creation of a ProviderIndex to its own factory function. * Added a cache file for tags. - Following what was done for providers, a TagIndex class has been added. This class can serialize and deserialize objects from json. Repo and RepoPath have a new method 'packages_with_tags', that uses the TagIndex to compute a list of package names that have all the tags passed as arguments. On Ubuntu 14.04 the effect if the cache reduces the time for spack list from ~3sec. to ~0.3sec. after the cache has been built. * Fixed colorization of `spack info`
2017-09-05Fixed bug in `spack env` due to missing argument. (#5280)Massimiliano Culpo3-7/+58
This command broke after #5109. It was using the default value for the "dirty" argument in `setup_package`. Now it adopts the same logic as in `spack install`. Changed help for '--clean' and '--dirty'. Improved coverage of spack env.
2017-09-01Set default cmake build_type to Release for llvmscheibelp1-1/+1
Override CMake "build_type" variant to default to "Release" for llvm package.

2017-08-30Slightly better error matching when parsing spack logs (#5236)Andrey Prokopenko1-1/+1
2017-08-29Added unit tests for Spec.__init__ exceptional pathsalalazo1-0/+11
2017-08-29Fixed bug in Spec._dup, updated docstringalalazo1-7/+17
The private method `Spec._dup` was missing a line (when setting compiler flags the parent spec was not set to `self`). This resulted in an inconsistent state of the duplicated Spec. This problem has been fixed here. The docstring of `Spec._dup` has been updated.
2017-08-29Make Spec construction simpler (#5227)Todd Gamblin1-27/+26
2017-08-28Add --show-full-compiler option to 'spack find'Matthew Scott Krafczyk2-2/+12
When 'spack find' is invoked with the '--show-full-compiler' option, the compiler flags and version are shown for each spec that is found.
2017-08-25Removed default value for 'dirty' function argument. (#5109)Massimiliano Culpo1-3/+3
This change is done to avoid inconsistencies during refactoring. The rationale is that functions at different levels in the call stack all define a default for the 'dirty' argument. This PR removes the default value for all the functions except the top-level one (`PackageBase.do_install`). In this way not defining 'dirty' will result in an error, instead of the default value being used. This will reduce the risk of having an inconsistent behavior after a refactoring.

2017-08-25Improve grammar in build log error message. (#5214)Todd Gamblin1-2/+7
- "1 error found" instead of "1 errors found" - don't print any build log context if no errors were found; just refer the user to the build log.
2017-08-25Add contributors link to Sphinx docs (#5213)Mark C. Miller1-1/+1
2017-08-25Respect --insecure (-k) flag when fetching list_url. (#5178)Sergey Kosukhin1-3/+33
* Respect --insecure when fetching list_url. * Ensure support for Python 2.6, and that urlopen works for python versions prior 2.7.9 and between 3.0 and 3.4.3.
2017-08-24test/gpg: init from the testing key directoryBen Boeckel1-11/+2
The old testing pattern set an attribute on the parser directly. Now that there is a parsed flag, use it instead.
2017-08-24gpg: add an argument for the import directoryBen Boeckel1-2/+8
This is hidden because it is only meant for use by the tests.
2017-08-23Improve Spec literals, add Spec.from_dict() (#5151)Massimiliano Culpo4-199/+472
* Simplified Spec.__init__ signature by removing the *dep_like argument. The `*dep_like` argument of `Spec.__init__` is used only for tests. This PR removes it from the call signature and introduces an equivalent fixture to be used in tests. * Refactored ``spec_from_dict`` to be a static method of ``Spec`` The fixture ``spec_from_dict`` has been refactored to be a static method of ``Spec``. Test code has been updated accordingly. Added tests for exceptional paths. * Renamed argument `unique` to `normal` + added LazySpecCache class As requested in the review the argument `unique` of `Spec.from_literal` has been renamed to `normal`. To avoid eager evaluations of `Spec(spec_like)` expressions a subclass of `collections.defaultdict` has been introduced. * Spec object can be keys of the dictionary for a spec literal. Added back the possibility use a spec directly as a key. This permits to build DAGs that are partially normalized.
2017-08-23Add --source option to spack install (#4102)Christoph Junghans3-0/+27
- -- source will copy source into prefix along with the package. - added a test for --source, as well

* add test for lua and node handling in sbang patching (cf #5086)
2017-08-22Add testing for new build output.Todd Gamblin3-2/+55
- Update handling of ChildError so that its output is capturable from a SpackCommand - Update cmd/install test to make sure Python and build log output is being displayed properly.
2017-08-22Make install command reusable within single Spack runTodd Gamblin3-21/+48
- install and probably other commands were designed to run once, but now we can to test them from within Spack with SpackCommand - cmd/install.py assumed that it could modify do_install in PackageBase and leave it that way; this makes the decorator temporary - package.py didn't properly initialize its stage if the same package had been built successfully before (and the stage removed). - manage stage lifecycle better and remember when Package needs to re-create the stage
2017-08-22SpackCommand uses log_output to capture command output.Todd Gamblin5-43/+29
2017-08-22log_ouptut can take either a filename or a file objectTodd Gamblin1-55/+93
2017-08-22Display build output on ProcessError, instead of Python context.Todd Gamblin2-29/+200
- If a failure comes from an external command and NOT the Python code, display errors highlighted with some context. - Add some rudimentary support for parsing errors out of the build log (not very sophisticated yet). - Build errors in Python code will still display with Python context.
2017-08-22Limit package context to 3 lines and colorize in error output.Todd Gamblin1-4/+16
2017-08-22Config scopes are now returning OrderedDicts instead of dicts. (#5183)Massimiliano Culpo3-3/+73
It seems 8f21332fec4c8adb5349ff90e30bb0e4f75e090e introduced a bug in that normal dictionaries are returned from ConfigScope objects instead of OrderedDicts. This is fixed here.
2017-08-21Add environment variables to path substitutionMatthew Scott Krafczyk3-22/+52
Update documentation on config file variable substitutions and add expansion of environment variables in config files.
2017-08-21Added custom messages for conflicts directive. fixes #4965 (#5083)Massimiliano Culpo2-8/+26
Users can now add an optional custom message to the conflicts directive. Layout on screen has been changed to improve readability and the long spec is shown in tree format. Two conflicts in `espresso` have been modified to showcase the feature.
2017-08-20Unbuffer so that output from packages appears when redirectingTodd Gamblin2-2/+65
- Python I/O would not properly interleave (or appear) with output from subcommands. - Add a flusing wrapper around sys.stdout and sys.stderr when redirecting, so that Python output is synchronous with that of subcommands.
2017-08-20Add tests for output redirection.Todd Gamblin1-0/+95
2017-08-20Preserve verbosity across installs when 'v' is pressed.Todd Gamblin3-66/+159
- 'v' toggle was previously only good for the current install. - subsequent installs needed user to press 'v' again. - 'v' state is now preserved across dependency installs.
2017-08-20Fix exit call in `SpackError.die()`Todd Gamblin1-3/+3
- Previously we would use `os._exit()` in to avoid Spack error handling in the parent process when build processes failed. This isn't necessary anymore since build processes propagate their exceptions to the parent process. - Use `sys.exit` instead of `os._exit`. This has the advantage of automatically flushing output streams on quit, so output from child processes is not lost when Spack exits.
2017-08-20Rework output redirection in Spack.Todd Gamblin5-237/+267
- Simplify interface to log_output. New interface requires only one context handler instead of two. Before: with log_output('logfile.txt') as log_redirection: with log_redirection: # do things ... output will be logged After: with log_output('logfile.txt'): # do things ... output will be logged If you also want the output to be echoed to ``stdout``, use the `echo` parameter:: with log_output('logfile.txt', echo=True): # do things ... output will be logged and printed out And, if you just want to echo *some* stuff from the parent, use ``force_echo``: with log_output('logfile.txt', echo=False) as logger: # do things ... output will be logged with logger.force_echo(): # things here will be echoed *and* logged A key difference between this and the previous implementation is that *everything* in the context handler is logged. Previously, things like `Executing phase 'configure'` would not be logged, only output to the screen, so understanding phases in the build log was difficult. - The implementation of `log_output()` is different in two major ways: 1. This implementation avoids race cases by using only one pipe (before we had a multiprocessing pipe and a unix pipe). The logger daemon stops naturally when the input stream is closed, which avoids a race in the previous implementation where we'd miss some lines of output because the parent would shut the daemon down before it was done with all output. 2. Instead of turning output redirection on and off, which prevented some things from being logged, this version uses control characters in the output stream to enable/disable forced echoing. We're using the time-honored xon and xoff codes, which tell the daemon to echo anything between them AND write it to the log. This is how `logger.force_echo()` works. - Fix places where output could get stuck in buffers by flushing more aggressively. This makes the output printed to the terminal the same as that which would be printed through a pipe to `cat` or to a file. Previously these could be weirdly different, and some output would be missing when redirecting Spack to a file or pipe. - Simplify input and color handling in both `build_environment.fork()` and `llnl.util.tty.log.log_output()`. Neither requires an input_stream parameter anymore; we assume stdin will be forwarded if possible. - remove `llnl.util.lang.duplicate_stream()` and remove associated monkey-patching in tests, as these aren't needed if you just check whether stdin is a tty and has a fileno attribute.
2017-08-20Make SpackCommand a bit more testableTodd Gamblin1-5/+15
- add fail_on_error argument - record exception and return code when the command fails
2017-08-20Fix issue with color formatting regular expression. (#5171)Todd Gamblin1-19/+20
- Fix issue with color formatting regular expression. - _separators regex in spec.py could be constructed such that '^' came first in the character matcher, e.g. '[^@#/]'. This inverts the match and causes transient KeyErrors. - Fixed to escape all characters in the constructed regex. - This bug comes up in Python3 due to its more randomized hash iteration order, but it could probably also happen in a Python 2 implementation. - also clean up variable docstrings in spec.py
2017-08-19Make test_inspect_path work on Mac OS X without XCode (#5168)Todd Gamblin1-2/+8
- Mac OS X Sierra has no /usr/include by default - Instead of assuming there's an include directory in /usr, mock up a directory that looks like we expect.
2017-08-18sbang support: add node-js and fix luahealther1-1/+8
This adds sbang hook support for node-js and fixes the sbang filter for lua (the character class exclusion was swallowing newlines and reporting a false positive if lua was mentioned anywhere in the file).
2017-08-17Docs: Travis-CI Workflow (#5133)Axel Huebl1-0/+78
* Docs: Travis-CI Workflow Add a workflow how to use spack on Travis-CI. Future Work: depending if and how we can simplify 5101: add a multi-compiler, multi-C++-standard, multi-software build matrix example * Fix Typos
2017-08-17Colorize spack info. Adds prominence to preferred version. (#4994)Massimiliano Culpo2-33/+117
* Colorize spack info. Adds prominence to preferred version. fixes #2708 This uses 'llnl.util.tty.color' to colorize the output of 'spack info'. It also displays versions in the order the concretizer would choose them and shows the preferred in a line on its own and in bold. * Modified output according to Adam and Denis reviews. Section titles are not bold + black, but bold + blue. Added a new section named "Preferred version", which prints the preferred version in bold characters. * Further modifications according to Adam and Denis reviews. After "Homepage:" we now have a single space. Removed newline after each variant. Preferred version is not in bold fonts anymore. Added a simple test that just runs the command.
2017-08-17Improved error message for unsatisfiable specs (#5113)Massimiliano Culpo1-4/+13
* Improved error message for unsatisfiable specs. fixes #5066 This PR improves the error message for unsatisfiable specs by showing in tree format both the spec that cannot satisfy the constraint and the spec that asked for that constraint. After that follows a readable error message.
2017-08-17Relaxed constraints on config.yaml structure (#5115)Massimiliano Culpo1-1/+0
This PR allows additional unused properties at the top-level of the config.yaml file. Having these properties permits to use two different versions of Spack, one of which adds a new property, without receiving error messages due to the presence of this new property in a configuration cache stored in the user's home.
2017-08-16buildcache fixes: index.html & unsigned installsPatrick Gartung1-20/+21
This fixes a syntax error in the index.html file generated by the "spack buildcache" command when creating build caches. This also fixes support for installing unsigned binaries.
2017-08-16Add tab completion & update docs for buildcacheAdam J. Stewart2-67/+91
This adds tab completion and fixes some formatting issues in the documentation for the "spack buildcache" command.
