Description
Assuming the backend's VNC server supports *CutText actions we can send text more quickly using the ClientCutText message: https://tools.ietf.org/html/rfc6143#section-7.5.6
Control flow:
- Test case calls type_string or perhaps a new call like paste_string
- Check the guest is in a state which supports the clipboard
- Check the string for any none latin characters or control codes which may break the operation
- Send ClientCutText message in VNC.pm
- Send the appropriate key sequence to perform paste/yank
Similarly ServerCutText can be used to send text in the opposite direction, if the test writer can reliably copy text to the clipboard.
Potential problems:
- The backends may not support the *CutText operations
- It may require a daemon to be running on the guest OS
- Not all software supports the clipboard.
Advantages:
- Faster
- Won't drop keypresses
- May work in most situations
I will investigate further if other attempts to speed up text input are not adequate.
