Reading the database repeatedly can be quite slow. We need a way to speed
up Spack when it reads the DB multiple times, but the DB has not been
modified between reads (which is nearly all the time).
- [x] Add a file containing a unique uuid that is regenerated at database
write time. Use this uuid to suppress re-parsing the database
contents if we know a previous uuid and the uuid has not changed.
- [x] Fix mutable_database fixture so that it resets the last seen
verifier when it resets.
- [x] Enable not rereading the database immediately after a write. Make
the tests reset the last seen verifier in between tests that use the
database fixture.
- [x] make presence of uuid module optional
Spack currently cannot run as a background process uninterrupted because some of the logging functions used in the install method (especially to create the dynamic verbosity toggle with the v key) cause the OS to issue a SIGTTOU to Spack when it's backgrounded.
This PR puts the necessary gatekeeping in place so that Spack doesn't do anything that will cause a signal to stop the process when operating as a background process.

This makes sure that a package's fetch_options are used when fetching
new versions to checksum. This allows working around problems with
slow servers or those requiring a cookie to be set.
Bug: Spack hangs on some Cray machines
Reason: The TERM environment variable is necessary to run bash -lc "echo $CRAY_CPU_TARGET", but we run that command within env -i, which wipes the environment.
Fix: Manually forward the TERM environment variable to env -i /bin/bash -lc "echo $CRAY_CPU_TARGET"
When trying to use an upstream Spack repository, as of f2aca86 Spack
was attempting to write to the upstream DB based on a new metadata
directory added in that commit. Upstream DBs are read-only, so this
should not occur.
This adds a check to prevent Spack from writing to the upstream DB

Before this PR a call to pkg.url_for_version was modifying
class attributes determining different results for subsequents
calls and an error when the urls was empty.
This recovers the old behavior of replace_prefix_bin that was
modified to work with elf binaries by prefixing os.sep to new prefix
until length is the same as old prefix.
Testing the install StopIteration exception resulted in an attribute error:
AttributeError: 'StopIteration' object has no attribute 'message'
This PR adds a unit test and resolves that error.
The new build process, introduced in #13100 , relies on a spec's dependents in addition to their dependencies. Loading a spec from a yaml file was not initializing the dependents.
- [x] populate dependents when loading from yaml
The distributed build PR (#13100) -- did not check the install status of dependencies when using the `--only package` option so would refuse to install a package with the claim that it had uninstalled dependencies whether that was the case or not.
- [x] add install status checks for the `--only package` case.
- [x] add initial set of tests
This change stores packages' configure arguments during build and makes
use of them while refreshing module files. This fixes problems such as in
#10716.

- [x] rework possible dependencies tests so that expected and actual
output are on the left/right respectively

Add a 'define_from_variant` helper function to CMake-based Spack
packages to convert package variants into CMake arguments. For
example:
args.append('-DFOO=%s' % ('ON' if '+foo' in self.spec else 'OFF'))
can be replaced with:
args.append(self.define_from_variant('foo'))
The following conversions are handled automatically:
* Flag variants will be converted to CMake booleans
* Multivalued variants will be converted to semicolon-separated strings
* Other variant values are converted to CMake string arguments
This also adds a 'define' helper method to convert any variable to
a CMake argument. It has the same conversion rules as
'define_from_variant' (but operates directly on values rather than
requiring the user to supply the name of a package variant).
* Buildcache: Install into non-default directory layouts
Store a dictionary mapping of original dependency prefixes to dependency hashes
Use the loaded spec to grab the new dependency prefixes in the new directory layout.
Map the original dependency prefixes to the new dependency prefixes using the dependency hashes.
Use the dependency prefixes map to replace original rpaths with new rpaths preserving the order.
For mach-o binaries, use the dependency prefixes map to replace the dependency library entires for libraries and executables and the replace the library id for libraries.
On Linux, patchelf is used to replace the rpaths of elf binaries.
On macOS, install_name_tool is used to replace the rpaths and dependency libraries of mach-o binaries and the id of mach-o libraries.
On Linux, macholib is used to replace the dependency libraries of mach-o binaries and the id of mach-o libraries.
Binary text with padding replacement is attempted for all binaries for the following paths:
spack layout root
spack prefix
sbang script location
dependency prefixes
package prefix
Text replacement is attempted for all text files using the paths above.
Symbolic links to the absolute path of the package install prefix are replaced, all others produce warnings.
PR #15212 added a new connect_timeout option that can be overridden
using fetch_options but had to specified per-version. This adds a new
per-package variable that can be used to override fetch_options for
all versions in the package. This includes connect_timeout as well
as 'cookie' (e.g. for the jdk package).
Packages can combine package-level fetch_options with per-version
fetch_options, in which case the version fetch_options completely
override the package-level fetch_options.
This commit includes tests for the added behavior.

* add --skip-unstable-versions option to 'spack mirror create' which skips sources/resource for packages if their version is not stable (i.e. if they are the head of a git branch rather than a fixed commit)
* '--skip-unstable-versions' should skip all VCS sources/resources, not just those which are not cachable
