I posted earlier that my daughter found that gphoto could no longer
download pictures from her digital camera after I upgraded
her machine to 2.2.16.
I tried 2.2.17pre6 to see if it made any difference.
I also did an strace against gphoto 0.2, 0.3, and 0.4.3.
Basically all versions do the same thing. After I click
on the button to fetch the picture index from the camera
the code does:
nanosleep({0, 1000000}, NULL) = 0
write(6, "\0", 1) = 1
select(7, [6], [], [6], {1, 0}) = 1 (in [6], left {0, 610000})
read(6, "\25", 1) = 1
select(7, [6], [], [6], {0, 0}) = 0 (Timeout)
nanosleep({0, 250000}, NULL) = 0
write(6, "\33", 1) = 1
nanosleep({0, 250000}, NULL) = 0
write(6, "S\6\0", 3) = 3
nanosleep({0, 500000}, NULL) = 0
write(6, "\0\21\5\0\0\0\26\0", 8) = 8
select(7, [6], [], [6], {0, 400000}) = 1 (in [6], left {0, 400000})
read(6, "\25", 1) = 1
nanosleep({0, 250000}, NULL) = 0
write(6, "\33", 1) = 1
nanosleep({0, 250000}, NULL) = 0
write(6, "S\6\0", 3) = 3
nanosleep({0, 500000}, NULL) = 0
write(6, "\0\21\5\0\0\0\26\0", 8) = 8
This code calls nanosleep a total of 58 times and takes 15 seconds of
real time if left to itself. During this time the X pointer is stuck in
molasses. After which it reports the timeout on the screen.
If I press a key on the keyboard at any time during the 15 seconds, the
code zips by to the point where it reports the timeout.
I.E. click (wait 15 second) for timeout
or
click (press key) timeout shows up more or less instantly.
The machine runs XFree86 4.0, has an AMD K6-3/400, and 128MB of RAM.
