* Support Vetu virtualization on Linux in addition to Tart on macOS
* api(portForward): ensure that rendezvousConn is closed
* Re-try SSH connections in integration tests
Because a VM might be still booting.
* controller(api): new "GET /vms/{name}/exec" WebSocket-based endpoint
* Split SSH connection and execution to avoid standard input handoff
* execstream: make Exit field a pointer again
To support serializing exit codes equal to 0.
* Implement server-side filtering for VMs by worker
* Parse more than one filter but error out when more than one is provided
* Fix off-by-one
* No need to use "\n" in Debugf()
* Ability to set VM's power state and retrieve backing Tart VM's name
* Validate user-provided "powerState" field
* Introduce TestSpecUpdatePowerStateSuspend
* Introduce TestSpecUpdatePowerStateStopped
* OpenAPI specification: add note about suspended VMs to "tartName" desc.
* Sometimes we need to wait more than 30 seconds
* Simplify state reconciliation and support changing Softnet settings
* Remove unused "updateFunc" parameter from syncOnDiskVMs()
* Don't take an address of a loop variable
* ensure → ensures
* updateVMState(): don't forget to update VMState
* Introduce TestSpecUpdateSoftnet integration test
* Update OpenAPI specification to include generation/observedGeneration
* API: introduce ability to watch a VM
* Document ?watch=true for GET /vms/{name} in the OpenAPI specification
* WatchVM: ensure that goroutine is terminated on early return with error
* WatchVM: close channels on goroutine exit
* WatchVM: ensure that we wait for the goroutine after additional barriers
* WatchVM: ignore unexpected keys instead of throwing an error
* WatchVM: perform context-aware writes to a bounded channel
* WatchVM: don't forget to close errCh on goroutine exit too
* WatchVM: don't close readyCh in goroutine to avoid ambiguity
* WatchVM: filter out spurious KVs that signify VM deletion
* Allow creating VMs with implicit CPU and memory
* Clarify why cpu/memory can be 0 a bit better
* Controller(API): don't forget to update DefaultCPU and DefaultMemory
* Add an integration test for implicit CPU and memory
* Introduce WebSocket-based RPC v2
* go test: add -ldflags="-B gobuildid"
* No need to change the "controller.workerNotifier.Notify()" error message
* No need to modify Protocol Buffers/gRPC generated code
* rpcWatch(): explain that connection shouldn't be normally be closed
* Avoid "port forwarding failed: " repetition in error messages
* Improve comments and avoid repetition in IP resolution errors
* Schedule opportunistically and more granularly
To avoid transaction conflicts.
* Measure scheduling loop iteration duration and log it at debugging level
* Use "continue NextWorker" instead of just "continue" for clarity
* Controller: emit lifecycle events when the VM gets restarted or deleted
* vm_{scheduling,run}_time → vm_{scheduling,run}_duration for clarity
* Update VM endpoint: only update VM started time when zero
* Support URLs in hostDir policies
We can't just blindly allow remote URLs since they might contain symlinks leading to outside the archive. Instead, let's support specifying URLs where the remote archive can come from.
Fixes#145
* Ignore Lint issue
* Reverted old validation logic
* Implement restart policy for VMs
* Do not update VM.Resource, we only use it as a read-only specification
* Err()/setErr(): use atomic.Pointer instead of sync.Mutex
* Controller API: introduce controller's information endpoint
* Prevent generation of empty events after channel closure
* Allow events to be buffered in the events channel
* Controller API: introduce controller's information endpoint[1]
* IntegrationGuide.md: a couple of Python and Golang examples
* Rephrase a sentence

* Fail VMs if the worker had crashed/is unhealthy
* OnDiskName: properly handle cases when VM's name contains hyphens
* Worker: introduce Offline() method and check it before scheduling
* tart.List(): use Tart's JSON output
* OnDiskName: remove empty parts check
* Scheduler: move health-checking logic to a separate function
* Only fail "running" VMs
* Only fail orphaned VMs if they're in terminal state
* Integration tests
* Run healthCheckingLoopIteration() before schedulingLoopIteration()
* Worker: sync on-disk VMs only once at start
* Resources support
* Ability to provide VM and worker resources via the CLI
* orchard dev: always listen on :6120
* orchard dev: support --resources
* REST API: provide resource defaults when creating VM
* OpenAPI: document "resources" field
* orchard dev: serve Swagger API documentation on /v1/
* Integration guide
* Generic Events
We can try to use these generic events for script execution and storing of the output logs in events with `log` kind.
* Lint issues
* Cleanup events upon VM deletion
* Basic integration test
* Run an actual VM in tests
