A helper class that finds valid StackHub licences on SkyArc systems. Note that the StackHubLic class and extension disabling is only available in SkySpark 3.0.13 or later.
Copy and paste the Fantom class below into your SkyArc project.
Repeated calls to the findXXX() methods whittle down the number of valid licences until one is left. The remaining licence may be retrieved with get().
A LicErr is thrown should no licence match the given criteria. This may be caught to disable the containing SkyArc extension.
licence validation may be performed during the extension onStart() event. Typical usage would be:
using skyarcd::Ext
using skyarcd::ExtMeta
using haystack::Ref
using stackhub::StackHubLic
@ExtMeta { name = "acmeExt" }
const class AcmeExt : Ext {
** Validate the licence file.
override Void onStart() {
try {
lic := LicHelper(sys)
.findVendor(Ref("87654321-87654321", "Acme"))
.findPackage(Depend("acmeExt 1.0"))
.findValid.get
cap := LicHelper.parseCapacity(lic)
// ... validate licence capacity here ...
log.info("${lic.product.dis} licensed to ${lic.licensee} --> okay")
} catch (LicErr err) {
// if a valid licence can not be found, disable this extension
StackHubLic.extToFault(this, err.msg)
}
}
}
Note findVendor() should be called with your StackHub Vendor ID available from the My Products page.
findPackage() should probably be called with the details of the current pod:
findPackage(Depend("${typeof.pod.name} ${typeof.pod.version}"))
