V0.33

v0.33

includes the following changes:

• Fixes a slight screen corruption on 80 column display. When highlighting the verify ones option the first two digits of DoD 5220.20-M disappear. This patch fixes that issue.@PartialVolume #348
• For some controllers/drivers the readlink method of obtaining the bus type for GUI display does not work. If we haven't already resolved the bus type, we then also check smartctl for the transport protocol for SAS. @PartialVolume #350
• Check smartctl for unresolved bus types SATA @PartialVolume #358
• Changed message from (No ATA pass-thru) to (S/N: unknown) as the reason the serial number is unknown is because there is no ATA pass through for the chipset being used by the USB to SATA adapter, basically we are making the message more meaningful for the end user rather than for the engineer/programmer that may understand the previous terminology used. @PartialVolume @Firminator #356
• Add drive temperature monitoring and display temperature in degrees Celsius in the GUI. Requires the kernel drivetemp module and makes use of the hwmon sub system in the kernel to extract drive temperatures. Nwipe will automatically load the drivetemp module if it's available. @PartialVolume #360 #361 #364
• Remove /dev/ from gui for long device names. This fixes column alignment issues in the gui with nvme drives i.e. nvme0n1 etc. If the drive name including path exceeds 8 characters the /dev/ is removed and prefixed with spaces to a total max length of 8 characters. @PartialVolume #365
• Add -q --quiet option - anonymize serial numbers and SMBIOS-DMI data. This anonymizes serial numbers and related identifiable information for drives and hardware but does not remove model information in both the GUI and the log displayed by stdout at the end of a wipe and also in the log file if enabled in options. This feature is useful for uploading logs when submitting bug reports. @PartialVolume #366 #367 #371 #379 #383
• Fixes a intermittent FAILED message that is displayed in the summary table when the message should have been UABORTED. The incorrect FAILED message only occurred when using control-C to abort a wipe. @PartialVolume #373
• When many verification or pass errors are detected the status line can wrap on a 80 column display. This patch makes the error message more succinct which will free up about 10 characters & prevents the line wrapping. @PartialVolume #374
• Fixes a problem that occurs with a unresponsive drive that causes the ETA to grow to an enormous value. We now do not calculate an individual drives ETA when the throughput of the drive is zero so avoiding the overall ETA being incorrect for drives that are working correctly when multiple drives are being simultaneously wiped. While a individual drives ETA is calculated it is not displayed but only used to determine the overall ETA when all drives have completed. @PartialVolume #375
• Add temperature monitoring and display with NVMe drives. @PartialVolume #377 #380 #381
• When one of the two verify only methods are selected change the drive selected text from WIPE to VRFY to indicate the drive is not being wiped, but is only being verified. @PartialVolume #378
• Fixes a incorrect sector, block and device sizes in 32 bit builds only as displayed in the nwipe log. This problem had no affect on the wipe as the issue was caused by a incorrect format specifier that affected the log text only. @PartialVolume #387 #388
• Fixes a issue where temperatures may not have been available on Debian systems due to the location of modprobe. Particularly relevant to Debian which when logged in as root doesn't put /sbin in the $PATH environment setting. This issue was not necessarily relevant for Linux distros based on Debian, for instance, Ubuntu where nwipe would have found the modprobe command. @PartialVolume #390 #391
• Improve wipe thread cancellation error checking. @PartialVolume #392
• Improve GUI thread messaging if a pthread_join fails. @PartialVolume #393
• Fixed a missing serial number on SAS drive.@PartialVolume #394
• Added ISAAC-64 for 64 bit systems. Thanks @chkboom #398 #401
• Fixes a problem with the Gutmann wipe where the random passes at the beginning and end were being re-arranged when only the inner passes should be rearranged. Thanks @chkboom #399
• Fixes a obscure incorrect summary table status, while the log text correctly reports the failure. If the drive becomes non responsive during the wipe, the MB/s throughput will slowly drop towards 0MB/s and will display a FAILURE -1 error. The logs will correctly display errors and nwipe's return status will be non zero, however the summary table may display erased rather than FAILURE, this is because
  the wipe thread exited prematurely without setting the pass error. This fixes the error by checking the context's result status, i.e non zero on failure and if pass equals zero it makes pass equal to one. This is then picked up by the summary table log code which then marks the status
  correctly as FAILURE in the summary table. @PartialVolume #400
• Fixes a spurious message on abort before wipe.This patch fixes a minor display issue that occurs when a user aborts a wipe before a wipe has started. It only occurs if the user had selected one or more drives for wipe and then aborted before starting the wipe. The spurious message only occurs in a virtual terminal, i.e. /dev/tty1, /dev/tty2, /dev/console It does not occur in terminal applications such as konsole, xterm, terminator etc. The spurious message that appears in the main window, states that "/dev/sdxyz 100% complete" along with garbage values in the statistics window. The message appears for a fraction of a second before being replaced with the textual log information that correctly states that the user aborted and no wipe was started. Basically the gui status information update function tries to update the data when the wipe hasn't even started. The fix is to only update the statistics information only if a wipe has started by checking the 'global_wipe_status' value which indicates whether any wipe started. '1' indicates that a wipe has started, else '0' if no wipe has started. @PartialVolume #406
• Fixes temperature update in drive selection window. This fixes a problem where the drive temperature is not updated
  automatically in only the drive selection window. The temperature is however updated correctly every 60 seconds during a wipe in the wipe status window. This bug would probably never be noticed by most people as usually the drive temperature changes slowly and only rises once a wipe has started. The only time I imagine it would have been noticed would have been if the drive temperature was already high and you were trying to reduce the temperature by cooling before starting a wipe. This has now been corrected so that the temperature in the drive
  selection window is updated every 60 seconds. @PartialVolume #407
• Fixes a zombie nwipe process running at 100% CPU on one core but only on a Konsole based terminal. This only occurred when the Konsole terminal is exited while nwipe is sitting at the drive selection screen but nwipe did not exit when the konsole terminal was closed. If nwipe is exited normally on completion of a wipe or aborted by using control C then this problem would not be seen. Also occurs during a wipe if the konsole terminal is closed without exiting nwipe first, again only on Konsole based terminals. @PartialVolume #408 #409
• Fixes a obscure segfault when --logfile option used with a non writable directory. @PartialVolume #410
