If two Specs have the same hash (and prefix) but are not equal, Spack
originally had logic to detect this and raise an error (since both
cannot be installed in the same place). Recently this has eroded and
the check no-longer works; moreover, when defining projections (which
may truncate the hash or other distinguishing properties from the
prefix) Spack was also failing to detect collisions (in both of these
cases, Spack would overwrite the old prefix with the new Spec).
This PR maintains a list of all "taken" prefixes: if a hash is not
registered (i.e. recorded as installed in the database) but the prefix
is occupied, that is a collision. This can detect collisions created
by defining projections (specifically when they omit the hash).
The PR does not detect collisions where specs have the same hash
(and prefix) but are not equal.
Fix syntax of conflict between numpy 1.21.0 and gcc11 to that the clingo
concretizer recognizes it.
In addition the upstream master branch was renamed to main.
* Switch hdf5 package from autotools to cmake.
* Add variant for building with zlib, default to ON.
* Update for format requirements.
* Format change.
* Fix breakage from last merge from develop.
Switch szip to use libaec (unrestricted encryption).
Remove 'static' variant: static libs will only be installed when
~shared.
* Improve args based on suggestions from pull request.
* Update code URL to github.com
Add/modify 4 depends_on lines to fix running "spack graph --deptype=link hdf5".
* Remove trailing whitespace.
* Remove dependencies added solely to make "spack greph --type=link" work.
* Add new version HDF5 1.8.22.
* Remove unnecessary java_check.
* Fix whitespace for style checks.
* Reverted zlib version dependency to 1.1.2:.
zlib variant removed.
api version default renamed "default".
* Remove blank line.
* Whitespace corrections.
* iRemoved unnecessary 'debug' variant.
* Fix typo in version number in conflict for '+szip'.
* Set default for tools variant to True.
Remove patch functions dependent on 'libtool' file that cmake doesn't
produce.
* Remove line to set ONLY_SHARED_LIBS to true.
Add post_install code to install only one version of tools with shared
linkage and original tool names.
* Remove trailing white space and import of glob package not used.
* Leave BUILD_TESTING set to default which is ON.
* Remove post_install code to install only one version of tools because
some dependent packages running tests in e4s testing are using
h5diff-shared. Keep both tools versions for now.
* No longer need to import os.
Instead of refusing to build +mpi with gcc10, add what I guess is now
the standard workaround, ie., `-fallow-argument-mismatch`.
Getting this into pfunit's cmake-based but kinda non-standard build isi
a bit ugly, but you gotta do what you gotta do...
Version 1.17 of DD4hep was renamed from "01-17-00" to "01-17", in line
with the naming conventions of previous releases. Since release archives
contain a subdirectory with the version string in it, this changes the contents
of the tarball ever so slightly, so the SHA-256 checksum must change as well.
Fix url to find newer versions, add newest version 4.0.2 and add
variants for
- cxxstd: To use a specific c++ standard
- static: Enable or disable build of static libraries
- boost: Boost support
- sqlite: SQLite support
- postgresql: PostgreSQL support
