267297 - Download rate gets screwed when changing the system time

Status: RESOLVED EXPIRED

(Toolkit :: Downloads API, defect)

Description

[Dimitris Mouchritsas]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041001 Firefox/0.10.1

I was downloading the Neverwinter Nights resources from Jeux Linux on
http://nwn.bioware.com/downloads/linuxclient.html when I noticed that my PC had
not the proper system time (with the recent daylight saving time change) so I
put the hour one hour back. Then I noticed that the download rate of my download
showed something like: -1923.-2 KB/sec and kept reducing (-2000, etc.) After a
while (maybe an overflow occured?) it was very large (3000 KB/sec) and now it's
coming down near the proper download rate (29KB/sec)


Reproducible: Always
Steps to Reproduce:
1. Start downloading a file (preferably a large one)
2. Change the system time one hour back (I changed it through KDE)
3. Watch the download rate change

Actual Results:  
By changing the hour from 14:32 to 13:32 gave me a change to the download rate
from 138 KB/sec (which is not true because of the first time I noticed the bug)
to -44 KB/sec.

Expected Results:  
Keep the download rate steady. I suppose one would need a separate timer and not
relate to the system clock for counting the download rate

The download itself does not seem affected, so this is why I'm reporting this as
a trivial bug.

Dup of https://bugzilla.mozilla.org/show_bug.cgi?id=250347 ?

Changing the clock in KDE didn't seem to affect the download.

Can you still reproduce this with a nightly build and a clean profile? If not,
please resolve this bug WORKSFORME.

I can confirm this bug with the Suite's Download Manager (Mozilla/5.0 (X11; U;
Linux i686; en-US; rv:1.8b) Gecko/20050217).
With Firefox (Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050317
Firefox/1.0.2) changing the clock (with "date --set") to a date in the future
decreases the displayed download rate, changing to a date in the past stops the
progress bar from working. The download is not affected by this.

Sorry for spamming. Suite recent nightly (Mozilla/5.0 (X11; U; Linux i686;
en-US; rv:1.8b2) Gecko/20050402) shows same behaviour as Firefox, ie download
bar stops working when setting clock to a date in the past.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
