218419 - parent.output.document.write(line); doesn't work sometimes

Status: RESOLVED EXPIRED

(Core :: DOM: Core & HTML, defect)

Description

[Fabian Seitz]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5b) Gecko/20030827

The given URL is the address of our chat, which is based on the open source chat
PHPOpenChat. This chat works basically through a JavaScript, which runs in an
endless loop in a blind frame and writes the lines in the display frame. The
function is just :

function wrt(line){
 parent.output.document.write(line);
}

Until Mozilla 1.3 or so everything worked alright. Since Mozilla 1.4 some lines
are dropped occasionally, although Mozilla has received them.
The error is not reproducable.

I've created a test account.
Username: mozillatester
Password: mozilla

Unfortunately the whole chat is in German.


Reproducible: Sometimes

Steps to Reproduce:
1. chat
2. from time to time lines are not shown
3.

Actual Results:  
Most of the lines are shown, but some not.

Expected Results:  
All lines should be shown.

DOM, not JS.

A small testcase would be invaluable here.

Comment 2

[Fabian Seitz]

I really would like to give you some examples, but I don't know how. I logged
the output of this blind frame and saw that all lines are put out, but some are
not shown. I couldn't see any difference between those which are shown and those
which not. The only hint I have is that all lost messages in the chat are
private ones. That's the reason why I can't give you any examples.
All I can say is that I worked well in the past but does not now.

Can you give me any hints how I can create a testcase which is suitable for your
purposes ?

I'm not even able to login with mozillatester as an username and mozilla as
password. I get
"Teilnahme verweigert! Das Kennwort ist falsch."
error message. There is not much to go on here.

Sorry. After such a long time the account was deleted automatically.
I reopenend the account for testing purposes.

I checked that chat room and the generated code is so long, also poor markup
code, full of js functions (scroll functions also permanently ON), that there is
no way we will ever be able to construct a testcase out of this or ever be able
to identify whatever bug there might be with the Mozilla browser **if there is
actually a real bug with Mozilla here after all**. The page is continuously,
endlessly downloading, parsing and rendering new lines in the frame.

mmh, well - I just thought I report it because Opera and Internet Explorer work
well with the chat, and Mozilla did too with some very old versions. Maybe some
code cleaning on the page will help. Thank you anyway.

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.
Thank you for your help in this matter.
