Package: duplicity
Version: 0.6.08b-1+b1
Severity: important
I believe I had a connectivity problem which interrupted a transfer, and
since then duplicity has failed on every run saying:
"time not moving forward at appropriate pace - system clock issues?"
- which was the result of a failed assertion.
I examined the surrounding code:
if dup_time.curtime == dup_time.prevtime:
time.sleep(2)
dup_time.setcurtime()
assert dup_time.curtime != dup_time.prevtime
... this appears at first glance to get the current time, sleep for two
seconds, and then get the current time again, before comparing the two times.
.. however having modified the code to print the time stamps, and
subsequently investigating dupclicity's metadata, it would appear that
both pretime and curtime are set from the timestamp of a file, and thus
the test always fails. To the best of my knowledge there are no system
clock issues on this system, and the error appears to be a duplicity bug.
The system has been running squeeze for a while, and duplicity was updated
from lenny-backports to squeeze during September (duplicity
0.6.08b-1~bpo50+2 -> 0.6.08b-1+b1).
I have not investigated further, but see output below for the details of
the modified asssertion etc. etc.
A search of google would appear to show multiple people hitting the same
issue in the past.
HTH.
Thanks,
Tim.
