The purpose of this is to read year, month, day, hours
minutes and seconds into variables for updating in the GUI
prior to writing back to the system.
For systems isolated from the internet this will allow the
user to update system date/time from the nwipe GUI rather than
having to drop into the command line.
To complete this feature next will be to create the write_system_datetime
function.
Created a function that truncates a string that is printed
to a window if the string should exceed the window width.
This prevents the line wrap that occurs with mvwprintw
when the window width is not wide enough. This mainly
occurs with a 4:3 ratio monitor, 80 columns wide.
Created a window that shows a preview of organisational,
customer and date time information that will be added to
the PDF report. Items within the preview can be selected
which takes you to the relevant window for editing the
data. This can be optionally displayed before the drive
selection window is displayed.
To complete this I need to add a further entry in the
config window to allow editing date & time. Plus a
function needs to be added to truncate the strings
based on window width as some address strings could
be wider than the window and mess up the display as
they wrap to the next line.
When using backspace or esc to abort customer deletion,
first customer in list would incorrectly be deleted.
Corrected by this fix.
Also when aborting customer selection, first customer
in list would be automatically selected. Also corrected
by this fix.
Removed the csv field double quotes from the customer
selection list as displayed on screen. The double quotes will
still obviously exist in the csv file and are required
for the code to work correctly in various places. However, for
human readable text they are removed before displaying the
customer details line on the selection screen as it makes the
list look less 'busy' on screen hopefully.
I also fixed a issue where spaces were incorrectly being removed
from the customer details when filtering for printable characters
only.
PDFGen20 Started creating new GUI dialogs. A Configuration dialog and sub dialogs for allowing the user to enter business and customer details. Further dialog windows and code to be added...
If you are running nwipe within the KDE konsole
terminal and you resize the window by pulling on
the corners, occasionally nwipe will exit with the
error message:
"GUI.c,nwipe_gui_select(), loop runaway,
did you close the terminal without exiting nwipe?
Initiating shutdown now"
The loop runaway detection has been made less sensitive,
i.e 32 iterations per second of the GUI update can now
be completed before a loop runaway is detected. previously
it was 8. In practise when sizing the konsole window,
anywhere between 1 and 17 iterations will occur.
Fixes to apparent and real disc size fields in PDF based on use
of c->Calculated_real_max_size_in_bytes.
Minor changes to HPA status messages for consistent messaging.
When HPA and DCO sector information cannot be obtained display the
message "HPA/DCO data unavailable, can not determine hidden sector
status" in the information field on the PDF.
Determine human readable size for the c->Calculated_real_max_size_in_bytes
as used in the PDF real disc size field.
Instead of >>FAILURE!<< -1 when a I/O error occurs display >>IOERROR!<< -1
in the GUI.
Simplified the code that determines whether a HPA/DCO
is present and in the process fixed some related bugs
to do with the HPA/DCO fields in the PDF document
displaying incorrect information in some drive specific
cases.
Fixed a issue that occurs when a drive is attached via a USB adapter
that doesn't correctly pass the ATA commands for HPA/DCO determination.
It incorrectly set the HPA_status as enabled when in fact it should
have determined that DCO was accessible and a comparison against
the size as returned by libata and the real max sectors which in this
particular adapters case worked, was sufficient to correctly determine
whether there were hidden sectors or not.
Now fixed, so HPA status is now determined correctly even on some
less than ideal USB adapters.
The Seagate EXOS family of drives don't support the ATA
drive configuration overlay (DCO) command, however they do
support host protected area (HPA). Therefore these drives
can have hidden sectors.
The code was changed to accommodate the slightly different
way these drives respond to a hdparm -N, that is, the
response is accessible max address enabled or
accessible max address disabled. The new code correctly
determines a the status of a drive in regards to
whether it has hidden sectors or not and what it's
apparent and real size is.
Changed the way percentage is calculated. As we
are dealing with large numbers and for some reason
printf prints a double that is 99.99999999999 as
100.00 when a precision of two is specified I wrote
a function that creates a percentage string such that
99.99999999999 is displayed as 99.99%. This is important
in the report as a disc with one hidden sector will now
correctly show as 99.99% erased and not 100.00% erased.
Many changes related to DCO real max sectors and HPA set and real
sectors and how they are processed and used in the PDF creation
function. More testing is required until I'm happy this works
correctly with lots of different hardware including USB adapters
that don't support DCO/HPA and also drives that don't support
DCO/HPA such as the Seagate Enterprise EXOS drives.
