* Preliminary support for include URLs in spack.yaml (environment) files
This commit adds support in environments for external configuration files obtained from a URL with a preference for grabbing raw text from GitHub and gitlab for efficient downloads of the relevant files. The URL can also be a link to a directory that contains multiple configuration files.
Remote configuration files are retrieved and cached for the environment. Configuration files with the same name will not be overwritten once cached.
Extend the semantics of package requirements to
allow using them also under a virtual package
attribute in packages.yaml
These requirements are enforced whenever that
virtual spec is present in the DAG.
Per #32214, the existing patch `92b2c...` for `gcc@11:` only applies
cleanly for `libzmq@4.3.3:4.3.4`. This PR adds a conflict for earlier
versions, as they cannot be patched due to different context.
For `gcc@11`, this leaves the most recent two versions available (a
satisfactory compromise).
For `gcc@12`, however, there is another existing conflict that makes
these most recent two versions unavailable. This PR adds an upstream
patch for the single most recent version that allows compilation with
`gcc@12` for that most recent version.
Starting point:
- `gcc@11` concretizes on all versions, attempts to apply patch on
`@4.2.3:4.3.4`, and only succeeds to apply patch on `@4.3.3:4.3.4`,
- `gcc@12` concretizes on `@:4.3.1` (and `@master`), attempts to apply
patch on `@4.2.3:4.3.1`, fails to apply patch on all.
Ending point:
- `gcc@11` concretizes on `@4.3.3:4.3.4` (and `@master`), attempts and
succeeds to apply patch on `@4.3.3:4.3.4`,
- `gcc@12` concretizes on `@4.3.4` (and `@master`), attempts and
succeeds to apply patch on `@4.3.4`.
Verified with environment build:
```yaml
spack:
specs:
- libzmq@4.3.4%gcc@12.1.0
- libzmq@4.3.4%gcc@11.3.0
- libzmq@4.3.3%gcc@11.3.0
view: false
```
which returns the following:
```console
