[Bug-ddrescue] ddrecue GUI bug, progress report

[Petr Slansky]

Gentlemen,

I want to report a small problem with ddrescue and I think it is a bug in
ddrescue.

I use ddrescue often to copy data from one disk to other. And I already
observed several times that ddrescue stops to show progress on the screen. I
decided to report this problem. 

I copy one 128GB SSD disk to other SSD disk, the last report was after 85GB
were copied:

address@hidden:~# ddrescue -f /dev/sda /dev/sdb 

GNU ddrescue 1.16
Press Ctrl-C to interrupt
rescued:    85430 MB,  errsize:       0 B,  current rate:     115 MB/s
   ipos:    85430 MB,   errors:       0,    average rate:     115 MB/s
   opos:    85430 MB,     time since last successful read:       0 s
Copying non-tried blocks...

Copy operations continues in the background but progress is not updated (it
should be updated once a second). Once whole disk is copied, report is
updated:

Welcome - Parted Magic (Linux 3.5.3-pmagic)

address@hidden:~# ddrescue -f /dev/sda /dev/sdb 

GNU ddrescue 1.16
Press Ctrl-C to interrupt
rescued:   128035 MB,  errsize:       0 B,  current rate:   45710 MB/s
   ipos:   128035 MB,   errors:       0,    average rate:     179 MB/s
   opos:   128035 MB,     time since last successful read:       0 s
Finished                   

I think this problem is random; it can happen after several gigabytes
transferred or it doesn't happen at all. It is not repeatable but it happens
with some probability.

With regards,
Petr
