161212 - Too many IMG SRC calls will hang mozilla.

Status: RESOLVED WORKSFORME

(SeaMonkey :: General, defect)

Description

[Matthew]

Too many IMG SRC calls will cause Mozilla to crash. In order to access the URL
you need an account at BBR. I was advised by a mod there to post the following
instructions:

1. Someone should go to http://www.broadbandreports.com/ and setup an account
titled "Bugzilla"

2. Send a private message to the moderator Kevin informing him you are from
Mozilla or Bugzilla, and need access to the "Stars Watercooler" he will send you
tool points.

3. Go to http://www.broadbandreports.com/prof/new and click the buttons
confirming you want premium

4. You can now access the example URL. Please post the account password on this
bug report. Sorry about the long process, but site rules prohibit me from
setting up the account myself.

Reporter:
Which Build ?
Can you please use a talkback enabled build and add the talkback ID from that
crash into this bug ?

Comment 2

[Matthew]

The build is 2002071808 and is talkback enabled, however the talkback feature
doesn't seem to activate when it crashes. It causes the browser to crash/freeze
and then it normally has to be killed. But even when it crashes all the way,
still it doesn't talkback. I double checked and it was talkback, because it has
activated talkback on a different crash...

Comment 3

[Matthias Versen [:Matti]]

you mean a freeze/hang and no crash ?
Talkback can only catch crashes.

Is there a flash on that page ?

Comment 4

[Ian Neal]

Can you provide another URL as the one above complains of not being in an active
or available forum
Can you try a more recent build?

Comment 5

[Matthew]

Yeah its more of a freeze/hang.It'll hang, and then I will have to forcefully
kill it and it'll then crash. I don't remember it sending a talkback report
though. How do I check the talkback IDs in Linux? And as far as not being able
to see the message, make sure to follow the instructions for getting an account
in my original report. If you'd rather, I'll try to create an HTML page with
tons of IMG SRC calls in order to attempt to duplicate the bug again. There was
no Flash on the page at all.

you can see submitted talkback IDs by running 
mozilla/components/talkback/talkback

yes, please.

Tweaking summary, orginal summary was "Too many IMG SRC calls will crash mozilla."

Reporter, any idea of the number of img src calls there were? Can try and grab
the page source using another browser and add it as an attachment? Is it still
happening on a recent build?

Comment 8

[Matthew]

I wish I could. However the moderators at the message board have put the post in
an archive and have been less than helpful as far as getting access to it.
Anyways I'm going to create a simple HTML page, and using my copy & paste skills
see how many it takes to crash it...

Comment 9

[Matthew]

Okay I've created more IMG SRC calls than any sane (and most insane) web
designers would use on their page in a test page. I can't get 1.0.1 to crash.
Currently using build 2002092619. Must have been a bug in that build. I
currently see no reason to leave this bug open. If I encounter the same problem
in the future I'll report back.

if this bug still exists on the trunk, then it still needs to be fixed.  how
many <img> were you testing with?  I tested 100000 with trunk build 20021011 and
it worked ok (took a bit to load, but didn't hang).

Comment 11

[Matthew]

I know that the amount on the webpage that originally caused mozilla to hang was
much less than 10,000. I know I tested around 5,000 IMG SRC calls myself and
didn't crash Mozilla.
