// cancelCmd represents the cancel command
|
|
var cancelCmd = &cobra.Command{
|
|
Use: "cancel [task id]",
|
|
Short: "Sends a cancelation signal to the goroutine processing the specified task",
|
|
Long: `Cancel (asynqmon cancel) will send a cancelation signal to the goroutine processing
|
|
the specified task.
|
|
|
|
The command takes one argument which specifies the task to cancel.
|
|
The task should be in in-progress state.
|
|
Identifier for a task should be obtained by running "asynqmon ls" command.
|
|
|
|
Handler implementation needs to be context aware for cancelation signal to
|
|
actually cancel the processing.
|
|
|
|
Example: asynqmon cancel bnogo8gt6toe23vhef0g`,
|
|
Args: cobra.ExactArgs(1),
|
|
Run: cancel,
|
|
