func (*Handlers) HandleAssignProcess ¶
func (h *Handlers) HandleAssignProcess(c backends.Context, recoveredID string, payloadType string, jsonString string, originalRequest string)
handleAssignProcess handles HTTP requests for process assignment to executors.
This function implements leader-based exclusive assignment with retry loop and timeout support. It handles four main scenarios: 1. Non-leader node - redirects request to cluster leader for exclusive assignment 2. Colony assignments are paused - waits for resume signal or timeout 3. Process found - assigns and returns the process immediately 4. No process available - waits for new processes to be submitted
Flow:
- If exclusiveAssign is enabled and this node is not leader: redirect to leader
- Validates request parameters and executor permissions
- Enters retry loop that continues until timeout is reached
- Each iteration calls controller.assign() to attempt process assignment
- If assignments are paused: waits on resume channel or timeout
- If no process found: waits for new process events via waitForProcess()
- Returns assigned process or appropriate error (timeout, forbidden, etc.)
Parameters:
- c: Gin HTTP context for the request
- recoveredID: Executor ID recovered from authentication
- payloadType: Expected message type for validation
- jsonString: Request body containing assignment parameters
- originalRequest: Raw request for leader redirection in cluster mode
