Packer can only install plugins from github.com, with
releases.hashicorp.com consulted first for HashiCorp-published plugins.
This has been a long-standing gap for air-gapped and policy-restricted
environments (#11164): the source address parser already accepts any
hostname, but both existing getters reject non-github.com sources at
install time.
Add a remote plugin getter that installs plugins from the host named in
a required_plugins source address. The host serves the directory
structure of releases.hashicorp.com under the source's path: an
index.json listing versions, and per version a SHA256SUMS file, the
zips it lists, and - when the zip names carry no plugin protocol
version - the version's manifest.json. A plugin published on
releases.hashicorp.com is therefore mirrored as a verbatim copy of its
tree, with every checksum file and signature upstream-authored. A
plugin published as GitHub release assets is mirrored by copying each
release's assets into a version directory, renaming their SHA256SUMS
file to the unprefixed convention with content unchanged, and writing
an index.json listing the versions. Both kinds of content can be
served side by side by one host.
Getter selection happens per source address: github.com sources keep
the release and github getters unchanged, while any other host is
served by the remote getter over HTTPS. Sources with three or more
components are supported, up to the existing 16-component limit, so
nested artifact-repository paths and hosts that embed the upstream
origin in their path all resolve.
Version discovery, constraint solving, checksum verification, and the
binary naming rules match the existing getters. The installed filename
is rebuilt from validated checksum-file fields and never taken from the
server's response, checksum entries matching neither known naming shape
are rejected rather than guessed at, and nothing the remote metadata
supplies is used to fetch from another origin or path. index.json
parsing is covered by fixtures captured from the live releases API, so
a format change there fails tests rather than user installs.
Closes#11164

- Enhanced logging for enforced block operations in HCP Packer.
* Remove PublishEnforcedBlocks function from Bucket struct
* Remove ExtractBuildProvisionerHCL function and unused imports
* Reverted the version upgrade
* Added the internal-sdk for the enforcedProvsioner api changes
* Enhance enforced provisioner handling and error reporting
- Update error handling in FetchEnforcedBlocks to return detailed errors instead of warnings.
- Modify GetCoreBuildProvisionerFromBlock to accept build name for overrides.
- Add tests for FetchEnforcedBlocks to ensure correct behavior and error handling.
- Implement diagnostics for unsupported legacy JSON templates.
* Implement enforced provisioner parsing and handling
- Introduced a new package `enforcedparser` to handle parsing of enforced provisioner blocks from HCL and JSON formats.
- Refactored existing code to utilize the new `ParseProvisionerBlocks` function from the `enforcedparser` package.
- Updated `GetCoreBuildProvisionerFromEnforcedBlock` method to convert enforced provisioner blocks into core build provisioners.
- Enhanced error handling and logging during the parsing process.
- Added tests for the new parsing functionality and ensured existing tests were updated to reflect changes.
- Modified `InjectEnforcedProvisioners` method in JSON registry to utilize the new parsing logic.

The GetBuilds function, available on both HCL2 and legacy JSON
configuration objects, used to return the Build interface.
This typing by interface is not useful in this instance, since all the
uses of `GetBuilds' are self-contained within Packer, and we're never
using any other implementation for it than `*CoreBuild`.
We've been relying on the dynamic type for all the builds being
*CoreBuild in some places of the code, so to avoid potential surprises
in the future, we'll change the signature now so it returns only
concrete types.
Since the protos for uploading an SBOM for a build have been changed to
use an enumeration instead of a plain string with the latest revisions
to the HCP Packer SBOM support feature, we update how we reference those
values for the SBOM format to use that enum instead.
Since packer now supports keeping track of SBOMs produced during a
build, we add the code to integrate those changes into the internal/hcp
package, so we do upload them on build completion.
The hcp-sbom provisioner is a provisioner that acts essentially like a
download-only file provisioner, which also verifies the file downloaded
is a SPDX/CycloneDX JSON-encoded SBOM file, and sets up its upload to
HCP Packer later on.
As we're trying to move away from gob for serialising data over the
wire, this commit adds the capability for Packer to pick dynamically
between gob or protobuf for the serialisation format to communicate with
plugins.
As it stands, if all the plugins discovered are compatible with
protobuf, and we have not forced gob usage, protobuf will be the
serialisation format picked.
If any plugin is not compatible with protobuf, gob will be used for
communicating with all the plugins that will be used over the course of
a command.
