In the HPC package manager, we want the fastest `zlib` implementation by default. `zlib-ng` is up to 4x faster than stock `zlib`, and it can do things like take advantage of AVX-512 instructions. This PR makes `zlib-ng` the default `zlib-api` provider (`zlib-api` was introduced earlier, in #37372).
As far as I can see, the only issues you can encounter are:
1. Build issues with packages that heavily rely on `zlib` internals. In Gitlab CI only one out of hundreds of packages had that issue (it extended zlib with deflate stuff, and used its own copy of zlib sources).
2. Packages that like to detect `zlib-ng` separately and rely on `zlib-ng` internals. The only issue I've found with this among the hundreds of packages built in CI is `perl` trying to report more specific zlib-ng version details, and relied on some internals that got refactored. But yeah... that warrants a patch / conflict and is nothing special.
At runtime, you cannot really have any issues, given that zlib and zlib-ng export the exact same symbols (and zlib-ng tests this in their CI).
You can't really have issues with externals when using zlib-ng either. The only type of issue is when system zlib is rather new, and not marked as external; if another external uses new symbols, and Spack builds an older zlib/zlib-ng, then the external might not find the new symbols. But this is a configuration issue, and it's not an issue caused by zlib-ng, as the same would happen with older Spack zlib.
* zlib-api: use zlib-ng +compat by default
* make a trivial change to zlib-ng to trigger a rebuild
* add `haampie` as maintainer

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()

e.g. 3.1.1 produces this during configuration when trying to install:
ERROR: This version of Botan requires at least gcc 11.0

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
|

* Fixed HeFFTe package spec to not do the smoke test prior to 2.2.0, where it breaks
* Convert test return to 'raise SkipTest'

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.
