* add an example of an external rocm configuration
* include more info
* generalize section to all GPU support
|

This reapplies 66f7540, which adds supports for hardlinks/junctions on
Windows systems where developer mode is not enabled.
The commit was reverted on account of multiple issues:
* Checks added to prevent dangling symlinks were interfering with
existing CI builds on Linux (i.e. builds that otherwise succeed were
failing for creating dangling symlinks).
* The logic also updated symlinking to perform redirection of relative
paths, which lead to malformed symlinks.
This commit fixes these issues.

#35042 introduced lazy hash parsing, but didn't remove a
few attributes from the parser that were needed only for
concrete specs
This commit removes them, since they are effectively
dead code.

* Uppercase global constants in spec.py

The heuristic for duplicate nodes contains a few typos, and
apparently slows down the solve for specs that have a lot of
sub-optimal choices to be taken.
This is likely because with a lot of sub-optimal choices, the
low priority, flawed heuristic is being used by clingo.
Here I split the heuristic, so complex rules that matter only
if we allow multiple nodes from the same package are used
only in that case.

fetch_cache_location was erroneously renamed to FETCH_cache_location
as part of #39428, breaking "spack module create".
|
|
Since #34821 we are annotating virtual dependencies on
DAG edges, and reconstructing virtuals in memory when
we read a concrete spec from previous formats.
Therefore, we can remove a TODO in asp.py, and rely on
"virtual_on_edge" facts to be imposed.

* Fix spack frozen on child process defunct

Computing str(spec) is faster than computing hash(spec), and
since all the abstract specs we deal with come from user configuration
they cannot cover DAG structures that are not captured by str() but
are captured by hash()

Delay lookup for abstract hashes until concretization time, instead of
until Spec comparison. This has a few advantages:
1. `satisfies` / `intersects` etc don't always know where to resolve the
abstract hash (in some cases it's wrong to look in the current env,
db, buildcache, ...). Better to let the call site dictate it.
2. Allows search by abstract hash without triggering a database lookup,
causing quadratic complexity issues (accidental nested loop during
search)
3. Simplifies queries against the buildcache, they can now use Spec
instances instead of strings.
The rules are straightforward:
1. a satisfies b when b's hash is prefix of a's hash
2. a intersects b when either a's or b's hash is a prefix of b's or a's
hash respectively

The median length of this list of 1. For reasons I don't know, `.sort()`
still like to call the key function.
This saves ~9% of total database read time, and the number of calls
goes from 5305 -> 1715.

* Do not impose provider conditions, if the node is not a provider
fixes #39455
When a node can be a provider of a spec, but is not selected as
a provider, we should not be imposing provider conditions on the
virtual.
* Adjust the integrity constraint, by using the correct atom
|
|
|
|
* Add "only_clingo", "only_original" and "not_on_windows" markers
* Modify tests to use the "not_on_windows" marker
* Mark tests that run only with clingo
* Mark tests that run only with the original concretizer

If a possible provider is not used to satisfy a vdep,
then it's not a provider of that vdep.
|
|
This even though right now we don't have cases where
the effect is on another package.

For the time being this directive prevents the vendored package
to be in the same DAG as the one vendoring it.

To avoid paying the cost of setup and of a full grounding again,
move cycle detection into a separate program and check first if
the solution has cycles.
If it has, ground only the integrity constraint preventing cycles
and solve again.

The "concretizer" section has been extended with a "duplicates:strategy"
attribute, that can take three values:
- "none": only 1 node per package
- "minimal": allow multiple nodes opf specific packages
- "full": allow full duplication for a build tool
|
|
These bugs would show up when we try to split nodes by
imposing different targets or different compilers to all
build dependencies.
