Subject: [PATCH 72/75] parted/ui: remove unneccesary information of command
|
|
|
0cb0b9 |
line
|
|
|
0cb0b9 |
|
|
|
0cb0b9 |
When some command fails, the information still exists in
|
|
|
0cb0b9 |
command_line buffer. When in command mode or interactive mode,
|
|
|
0cb0b9 |
if an interactive exception prompts, the remained information
|
|
|
0cb0b9 |
will be processed as option from user. This will raise some other
|
|
|
0cb0b9 |
information or even unexpected results. So before getting option
|
|
|
0cb0b9 |
input from user, clean the command line buffer.
|
|
|
0cb0b9 |
|
|
|
0cb0b9 |
Example: When the disk label is invalid and user tries to make
|
|
|
0cb0b9 |
new partition on the device with command like,
|
|
|
0cb0b9 |
mkpart 0 50%. Then parted will raise an exception
|
|
|
0cb0b9 |
telling an invalid disk label found and whether to correct it.
|
|
|
0cb0b9 |
But at this time 0 as the input of mkpart will be
|
|
|
0cb0b9 |
considered as the option input for the exception(yes/no).
|
|
|
0cb0b9 |
So one more exception will raised with error information.
