and found when using the RelWithDebInfo build type.  Change protobuf
to only support Release and Debug build types.

Increase the connect timeout for elfutils to 60 sec.  Elfutils (and
bzip2) tar files are on sourceware.org which is often slow to respond.

* added UQTk package

* Add missing expat dependency to uqtk

Spack's fflags are meant for both f77 and fc. Therefore, they must
be passed as FFLAGS and FCFLAGS to the configure scripts of
Autotools-based packages.

* use os.sep instead of null byte to pad replacement paths in binaries

* Prefix the pading os.sep's

Removed the code that was converting the old index.yaml format into
index.json. Since the change happened in #2189 it should be
considered safe to drop this (untested) code.

Since 1.9.0 is broken for Darwin, which impacts many developers, and
the fix is still a RC, let's keep the previous release as default.

This avoids distruption for OSX developers and CI.

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.

Add the python dependency and CMake hints when build with tests.
`spack install --tests=root adios2`

* ADIOS2: Version `master`

Rename branch version to supported, real development branch `master`.
The old name is legacy Spack when alternative development branch
names were not yet supported.

* ADIOS: Simplify via spec Variable

use the already defined local variable `spec` to shorten
lines

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.

    your current directory for a regex pattern.  ripgrep is similar to
    other popular search tools like The Silver Searcher, ack and grep.

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.

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.

* Add Ceres Solver version 1.14.0

* Add variants for Ceres Solver

* Add gmsh v4.5.4 with new options

This adds OpenCASCADE as an alternative to the oce package.
A new variant 'privateapi' is added to enable the gmsh private API.

* Make oce conflict with opencascade in gmsh

Added freeipmi package. Configure and build work fine, install only as root,
thus added warning and added reference to issue #4432 .

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

* davix: add cxxstd variant

Davix is written in C++, so add this variant to allow dependents to specify
this so a consistent ABI is used.

* davix: fix flake8 errors

Update WarpX for recent developments:
- add openPMD I/O (default: ON)
- remove electro-static solver option (now a runtime option)
- enable tiny profiler by default
- depend on new CXX std support in make scripts for C++14
- WarpX only supports 2D and 3D in cartesian dims
