This was reported to docker https://github.com/docker/docker/issues/281
11 when doing a docker pull there is a multi-line scrolling progress
bar, when running under rxvt-unicode the final line is duplicated.
I've captured a trace with script(1) and attached as docker-
pull.{time,log} which can be replayed with
scriptreplay -t docker-pull.time -s docker-pull.log
(I find "-d 0.3" makes it easier to catch the bug occuring).
With rxvt-unicode while the pull is happening it shows:
3.3: Pulling from library/alpine
985c5f84712b: Downloading [=============================================>
] 2.113 MB/2.323 MB
985c5f84712b: Pulling fs layer
But the second 985c5f84712b should have been overwritten by the first
and there should be a blank line after the "Pulling from". When running
under xterm, aterm and mlterm the output is:
3.3: Pulling from library/alpine
985c5f84712b: Downloading [====================================>
] 1.687 MB/2.323 MB
There are several phases, "Pulling ...", "Downloading ...", "Extracting
..." which should each overwrite each other. A more complex pull with
multiple lines is shown in the ticket, but I picked a simple one,
hopefully the script capture is enough to reproduce for you.
In https://github.com/docker/docker/issues/28111#issuecomment-259165408
I said that I think this might be down to the sequence
"<ESC>[1B<ESC>[1A^M" and might maybe have something to do with the
behaviour of the CUU and CUD cursor movement ANSI codes at the edge of
the screen, but frankly I'm out of my depth...
Thanks,
Ian.
