e5d6f28b4e binary caching: handle files misidentified as needing relocation (#6679)

28d8784ab9 Compiler flag handlers (#6415)
This adds the ability for packages to apply compiler flags in one of
three ways: by injecting them into the compiler wrapper calls (the
default in this PR and previously the only automated choice);
exporting environment variable definitions for variables with
corresponding names (e.g. CPPFLAGS=...); providing them as arguments
to the build system (e.g. configure).

When applying compiler flags using build system arguments, a package
must implement the 'flags_to_build_system_args" function. This is
provided for CMake and autotools packages, so for packages which
subclass those build systems, they need only update their flag
handler method specify which compiler flags should be specified as
arguments to the build system.

Convenience methods are provided to specify that all flags be applied
in one of the 3 available ways, so a custom implementation is only
required if more than one method of applying compiler flags is
needed.

This also removes redundant build system definitions from tutorial
examples

0192455885 spack install: make restaging the default (#6465)

'--dont-restage', inverting its meaning and the default behavior
of the command.

Skip collection of compilers which report an empty version (#6684)
Fixes #6200

For compilers that successfully run a version detection script but
don't actually return a version, Spack was keeping track of the
empty version and then failing when attempting to construct a
compiler spec. This skips any attempt to add a compiler entry when
no version is reported (but logs when a compiler fails to report
a version).

5727054c4a misc fixes, changed to EnvironmentModifications (issue #6501) (#6541)
* Support pruning of vars with Env from_sourcing_file (issue #6501)

- Blacklist string literals or regular expressions of environment
  variables that are to be removed from consideration as being affect
  by the sourcing of the file. Conversely, whitelist modifications
  that should not ignored.  Whitelisted variables have priority over
  blacklisting.
  Eg,

      EnvironmentModifications.from_sourcing_file
      (
          bashrc
          blacklist=['JUNK_ENV', 'OPTIONAL_.*'],
          whitelist=['OPTIONAL_REQUIRED.*']
      )

This modification can be used to eliminate environment variables that
are not generalized for modules (eg, user-specific variables).

* BUG: module prepend-path in wrong order (fixes #6501)

* STYLE: module variables in sorted order (issue #6501)

- looks nicer and also helps when comparing the contents of different
  module files.

* ENH: remove duplicates from env paths when creating modules (issue #6501)

- this makes for a cleaner module environment and helps avoid some
  unnecessary changes to the environment that are only provoked by
  redundancies in the PATH.

  eg,
      before PATH=/usr/bin
      after  PATH=/usr/bin:/usr/bin:/my/application/bin

  should only result in /my/application/bin being added to the PATH
  and not /usr/bin:/my/application/bin

Activate via the 'clean' flag (default: False):

    EnvironmentModifications.from_sourcing_file(bashrc, clean=True,..

According to the documentation here:

  http://www.sphinx-doc.org/en/stable/ext/autodoc.html

"For module data members and class attributes, documentation can either
be put into a comment with special formatting (using a #: to start the
comment instead of just #), or in a docstring after the definition."

f6c99d7beb Buildcache: relocate fixes (#6512)
* Updated function which checks if a binary file needs relocation.
  Previously this was incorrectly identifying ELF binaries as symbolic
  links (so they were being excluded from relocation). Added test to
  check that ELF binaries are not considered symlinks.

* relocate_text was not replacing paths in text files. Added test to
  check that text files are relocated properly (i.e. paths in the file
  are converted to the new prefix).

* Exclude backup files created by filter_file when installing from
  binary cache.

* Update write_buildinfo_file method signature to distinguish between
  the spec prefix and the working directory for the binary cache
  package.

`spack activate`). See #5559.

f6ead27b5b spack spec: don't show normalize + no hash for non concrete specs (#6417)

Group flags and values separated by space (#6169)
Fixes #6154

For compiler options which set values using the syntax "-flag value"
(with a space between the flag and the flag's value) the flag and
value were treated as separate and reordered. This updates Spack's
logic to treat the flag and value as a single unit, even if there is
a space between them. It assumes that all flags are prefixed with
"-" and that all flag values are not.

1484a94b1e spack buildcache: symlink and relative RPATH fixes (#6140)
* Skip rewriting files that are links (this also avoids issues with parsing
  the output of the 'file' command for symlinks)
* Fail rather than warn for several gpg signing issues (e.g. if there is no
  key available to sign with)
* Installation with 'buildcache install' only retrieves link and run
  dependencies (this matches 'buildcache create' which only creates tarballs
  of link/run dependencies)
* Don't rewrite RPATHs for a binary if the binary cached package was created
  with relative RPATHs
* Refactor relocate_binary to operate on multiple binaries (given as a
  collection of paths). This was likewise done for relocate_text and
  make_binary_relative

#3183 removed the print_help function from the "modules" module.
This adds it back so that if a user invokes 'spack load foo' without
having sourced an environment setup script, they will be prompted
to do so. This also improves the placeholder message to tell the 
user to invoke 'spack' as shell function rather than as an executable.

56bafdc282 database: rename installed_extensions_for
Views support activating packages, so rename the method because it will
soon query what is activated versus what is installed.

76305038ef determine full compiler version for gcc-7
Fixes #5778.

Spack uses 'gcc -dumpversion' to determine the full version of gcc.
'gcc -dumpversion' no longer gives the full version on gcc 7.2.0.
'gcc -dumpfullversion' is required instead. This PR detects when
'gcc -dumpversion' gives a truncated version of '7' and in that
case retrieves the full version with 'gcc -dumpfullversion'

update filename used for cc wrapper invocation debug log (#5837)
The name of the debug log written by the cc compiler wrapper was given
by Spec.short_spec, which includes the architecture. Somewhere along
the line Spec.format started adding spaces around the architecture
property so the filename started including spaces; the cc wrapper
script appears to ignore this, so files like spack-cc-bzip2-....in.log
(which record the wrapped compiler invocations) were not being
generated. This uses a different format string from the spec to
generate the wrapper log file names (which does not include spaces).

60a485591c Fix user specs which include already-installed packages (#5939)
* when a user-provided spec refers to an already-installed package, packages with patches applied were causing validation errors based on the recorded variants in the package's class

* avoid checks on all reserved variants (not just 'patches')

e5b8312de3 Auto install available pre-built packages from binary cache (#5242)
* basic functionality to install spec from a binary cache when it's available; this spiders each cache for each package and could likely be more efficient by caching the results of the first check

* add spec to db after installing from binary cache

* cache (in memory) spec listings retrieved from binary caches

* print a warning vs. failing when no mirrors are configured to retrieve pre-built Spack packages

* make automatic retrieval of pre-built spack packages from mirrors optional

* no code was using the links stored in the dictionary returned by get_specs, so this simplifies the logic to return only a set of specs

* print package prefix after installing from binary cache

* provide more information to user on install progress

function.

bd6378a6d2 Package.extends: update semantics when package isn't concrete (#5600)
This updates the logic for Package.extends so that if the spec
associated with the package is not concrete, it will report true if
the package *could extend* the given spec; generally speaking a
package could extend a spec as long as none of the details associated
with its extendee spec conflict with the given spec. When the spec
associated with the package is concrete, this function will only
report whether the package *does extend* the given spec. When both
the specs are concrete, the semantics are the same as before.
