49760 - composite sidebar URL causes images to display as broken

Status: VERIFIED WORKSFORME

(Core :: Graphics: ImageLib, defect, P2)

Description

[ekrock's old account (dead)]

Using Commercial 2000082108 on WinNT 4.0 SP4.

To repro:
1) visit above URL
2) note that most of the images on the page fail to display, and you see the
name of the image file instead; in particular, you see:

- "divider2" in the column on the right edge of the page
- "torpedo Kursk" in the center of the page

Here's the markup for divider2:
<img src="/images/hub2000/divider2.gif" hspace=0 vspace=0 align="top"
width="163" height="11" border=0>

Note that the image SRC doesn't begin with a space and it doesn't have a NAME
attribute, so this isn't a DUP of some other open image display bugs I've seen.

Additional info: got to this URL by clicking a news link in the cnn.com sidebar
panel. This creates a very strangely-formed URL with http://...http:// (see URL
above). I wonder whether this odd base URL is making it hard for netlib to find
the images?

Marking top100,regression,4xp,nsbeta3,correctness. Whatever's causing this is a
clear must-fix for nsbeta3.

hmm this isn't a case of a broken image - the images load fine if you remove the
referring url and go right to
http://cnn.com/2000/WORLD/europe/08/21/russia.submarine.cause/index.html

it seems like we were getting broken images from bug 48200 (which was just 
fixed), and bug 41924 was giving making those broken images give us bad alt 
text.

REOPENing. Not so fast, Ian -- these images are not broken, as in bug 41924, so 
I don't think this is a DUP. The images display fine:
1) in Nav4
2) if you change the URL to be something other than the funky glommed-together 
composite of two URLs

Thanks to R.K.Aa's observation, I think what is going on is this: we have a bug 
in which we no longer are correctly understanding these funky URLs; that bug is 
causing Necko to fail to locate the linked image files (probably because the 
doc's base URL is funky); and as a result, Mozilla thinks the image link is 
broken and is displaying whatever it's using for ALT text. 

Changing Summary from "most images on page fail to display (especially 
divider2)" to "composite sidebar URL causes images to display as broken." Will 
reassign to gagan due to suspicion that this is a networking URL decoding 
problem.

Reassigning to gagan for investigation of apparent problem in decoding URLs for 
linked images.

Fix for 48200 was checked in 15:36 but didn't fix this bug; it still behaves
like originally reported.

I suspect the P3 designation is by accident ... changing to P2 to get in on
people's radar (has been ignored for a month).  Does this problem still exist?

[Phil Peterson]

Not holding PR3 for this, so marking nsbeta3-. If there's still a critical bug 
here, please nominate for rtm with explanation.
