Adapt functions to work for external Knative
Remove Kn services cache from Clusters::Application::Knative
Knative function can exist even if user did not installed Knative via
GitLab managed apps.
-> Move responsibility of finding services into the Cluster
-> Responsability is inside Clusters::Cluster::KnativeServiceFinder
-> Projects::Serverless::FunctionsFinder now calls depends solely on a
cluster to find the Kn services.
-> Detect Knative by resource presence instead of service presence
-> Mock knative_installed response temporarily for frontend to develop
Display loader while `installed === 'checking'`
Added frontend work to determine if Knative is installed
Memoize with_reactive_cache(*args, &block) to avoid race conditions
When calling with_reactive_cache more than once, it's possible that the
second call will already have the value populated. Therefore, in cases
where we need the sequential calls to have consistent results, we'd fall
under a race condition.
Check knative installation via Knative resource presence
Only load pods if Knative is discovered
Always return a response in FunctionsController#index
- Always indicate if Knative is installed, not installed or checking
- Always indicate the partial response for functions. Final response is
guaranteed when knative_installed is either true | false.
Adds specs for Clusters::Cluster#knative_services_finder
Fix method name when calling on specs
Add an explicit check for functions
Added an explicit check to see if there are any functions available
Fix Serverless feature spec
- we don't find knative installation via database anymore,
rather via Knative resource
Display error message for request timeouts
Display an error message if the request times out
Adds feature specs for when functions exist
Remove a test purposed hardcoded flag
Add ability to partially load functions
Added the ability to partially load functions on the frontend
Add frontend unit tests
Added tests for the new frontend additions
Generate new translations
Generated new frontend translations
Address review comments
Cleaned up the frontend unit test.
Added computed prop for `isInstalled`.
Move string to constant
Simplify nil to array conversion
Put knative_installed states in a frozen hash for better read
Pluralize list of Knative states
Quey services and pods filtering name
This way we don't need to filter the namespace in memory.
Also, the data we get from the network is much smaller.
Simplify cache_key and fix bug
- Simplifies the cache_key by removing namespace duplicate
- Fixes a bug with reactive_cache memoization
