87164 - Progress updating is intermittent downloading large newsgroups

Status: RESOLVED WORKSFORME

(MailNews Core :: Networking: NNTP, defect)

Description

[[e-mail] (gone - use [e-mail] instead)]

Build ID:  2001-06-20-15, RedHat 7.1 (out of the box setup)

Summary: We're not getting good progress meter/throbber updating when
downloading large newsgroups.

Steps to Reproduce:

1.  Create a new account with at least 50,000 headers in a single newsgroup. 
(In my case news://news.netscape.com/mcom.beta.feedback.browser did the trick)
2.  Click on the newsgroup, and choose "Download All Headers".

Expected Results:

While expecting this to take a while due to the large number of headers, there
should always be throbber updating and progress meter updating occuring.

Actual Results:

I saw the throbber only update once every 3-5 minutes, and Moz stopped updating
the "Downloading X of 67231 headers" at # 59720, after which the program hung. 
Also, the progress meter was only updating every 20,000 newsgroups or so.

I just tried this on my Mac OS 9.1 build 2001-06-21-08, and although the
throbber and status bar synchronization could be better, it finished and
returned the app to a responsive state once it was done downloading the headers.

... and my linux box just finished now, too.  Even with 4.x, this takes a
considerable amount of time, but the real bug here is that we're not properly
updating progress.   Since I'm not freezing with this build, changing the scope
of this back to the progress updating.

Side note: this newsgroup takes 41 minutes to download on my Win2K machine using
4.x.  Your mileage may vary.

I'm downloading older trunks builds, will attempt to track this down to a batch
of checkins.

The earliest ftp.mozilla.org has builds is the 10th.  Checking bonsai now.

Seth, do you think this bug is a DUP of your bug 60822?

cleaning up nsbranch keywords.

Stephend, AFAICS bug 60822 is for downloading subscribable newsgroups, this bug
is for downloading headers from a single newsgroup.

Hwaara, indeed you are correct, thanks for the clarification.

Trying with rec.games.pinball on a server with ~1mo retention time (total articles 23K or so). It updated about once every 200 headers (noticeable lag, but only a few hundred ms), and the progress bar and throbber kept on spinning. Not stellar, but you can tell it's still running.
