Change how provenance information is captured from builds. While previously frontend passed the buildinfo sources with metadata, now all information is captured through buildkit. A frontend does not need to implement buildinfo and can't set incorrect/incomplete buildinfo for a build result. All LLB operations can now collect as much provenance info as they like that will be used when making the attestation. Previously this was limited to a single Pin value. For example now we also detect secrets and SSH IDs that the build uses, or if it accesses network, if local sources are used etc.. The new design makes sure this can be easily extended in the future. Provenance capture can now detect builds that do multiple separate subsolves in sequence. For example, first subsolve gathers the sources for the build and second one builds from immutable sources without a network connection. If first solve does not participate in final build result it does not end up in provenance. Signed-off-by: Tonis Tiigi <tonistiigi@gmail.com>
packageurl-go
Go implementation of the package url spec.
Install
go get -u github.com/package-url/packageurl-go
Versioning
The versions will follow the spec. So if the spec is released at 1.0. Then all versions in the 1.x.y will follow the 1.x spec.
Usage
Create from parts
package main
import (
"fmt"
"github.com/package-url/packageurl-go"
)
func main() {
instance := packageurl.NewPackageURL("test", "ok", "name", "version", nil, "")
fmt.Printf("%s", instance.ToString())
}
Parse from string
package main
import (
"fmt"
"github.com/package-url/packageurl-go"
)
func main() {
instance, err := packageurl.FromString("test:ok/name@version")
if err != nil {
panic(err)
}
fmt.Printf("%#v", instance)
}
Test
Testing using the normal go test command. Using make test will pull the test fixtures shared between all package-url projects and then execute the tests.
$ make test
curl -L https://raw.githubusercontent.com/package-url/purl-test-suite/master/test-suite-data.json -o testdata/test-suite-data.json
