Description JanS 2008-07-02 17:49:15 UTC
Description of problem:
While downloading rpm's yum displays download progress for file and overall
downloads progress as percentage information.
After something goes wrong (loss of network for a while), yum resumes
downloading from another mirror. After this percentage overall progress is not
well calculated. This could lead to value over 100% (as on attached screenshot)


Version-Release number of selected component (if applicable):
yum 3.2.16-2.fc9
Fedora 9, 2.6.25.6-55.fc9.x86_64

How reproducible:
It is easy to reproduce.
Try to update few bigger packeges and unplug ethernet in the middle of
downloading process for a while (not too long not too short, few seconds to
force yum to try another mirror) or disable wireless and plug ethernet after a
while.

Steps to Reproduce:
1. while yum is downloading rpm's, unplug your ethernet cable 
2. after a while plug in, to force yum to try another mirror but continue to
download
3. watch overall progress percentage (in brackets)
4. at the end you should see 101%, 102%, 103%, etc
  
Actual results:
98%, 99%, 100%, 101%, 102%, 103%, 104%, etc...

Expected results:
98%, 99%, 100%. Finished

 If you upgrade to the latest python-urlgrabber this should go away almost all
the time (incl. the case in the screenshot). Although for all corner cases you
need yum-3.2.17, when that comes out.

same bug with newest python-urlgrabber 3.0.0-8.fc9

I have allready uptodate python-urlgrabber.
And was able to reproduce ths bug once more (see attachment).

Comment 4 James Antill 2008-07-02 23:11:18 UTC
 Can you show the top part of that output ... as I said there are certain
conditions where urlgrabber can't fix it itself, for instance if the remote end
doesn't give urlgrabber the full size ... or if it all gets downloaded but then
doesn't checksum.
 Does it sound like any of that could have happened to you?

yum output, last comunicate during download was (118%)

see next attachement, screenshot from same situation as log, but caught in
action 104%.

I dont think that it is because of wrong full size got from internet, rather
from interrupiton. One can check sizes of this updates and compare with the
log.

Maybe its because of one of my yum extensions?

 Ok, after being very confused for a bit, I see the problem.
 This was actually fixed in
https://admin.fedoraproject.org/updates/F9/FEDORA-2008-5396 which is still in
updates-testing ... sorry. I thought I'd already moved it to updates, so just
took the version from there.

 I'll move it to updates now.
