82799 - Hang navigating a secure site which is having network problems

Status: VERIFIED WORKSFORME

(Core Graveyard :: Security: UI, defect, P1)

Description

[Simon Fraser [no longer active]]

I'm seeing a hang (in both psm2-enabled release and debug builds) navigating a 
secure site; in this case, I'm trying to connect to sourceforge.

Steps:

1. Go to http://sourceforge.net/. Because of akamai network problems, some
   images on the page fail to load; the throbber keeps spinning.
2. Click on the 'Login via SSL' link. At this point the browser hangs. It seems
   to be a threading issue; breaking into MacsBug never shows me a useful stack.

Blocker. I can't test other networking bugs.

I can reproduce this problem with a new profile too, so it's not just something 
funky in my profile.

I'm not sure this is a PSM bug.  If I visit https://www.verisign.com/ first.  
The page loads fine. I then go to http://www.sourceforge.net/ and see the 
behavior described.  If I then visit https://www.thawte.com/ that page loads 
fine as well.  Seems like there's something about that page that's causing the 
necko layer (or some layer above it) problems.

This problem appears to be related to the fact that parts of the site are not 
loading properly (the images), which itself has got better just now (I guess they 
were having some network issues), and I could make it hang up by hitting the stop 
button in the browser.

Maybe the SSL code doesn't deal well with cancelled connections?

Moving from Browser/Security:Crypto to PSM 2.0.

When I visited https://www.sorceforge.net, the connection just hung up on me. 
So I turned off TLS and tries again.  This time it CRASHED.

I can't load either https://sourceforge.net or http://sourceforge.net in linux
build 2001062206
Nothing happens.

javi, this is not mac only anymore. and it's different from bug 84219

ssaux: there's seems to be a bug when typing URL's into the location bar.  Have
you tried using File->Open Web Location?  That works for me.

Comment 12

[Bob Lord]

With today's build, I can visit https://sourceforge.net/ without trouble. No
hang, no crash.

I can't type into the location bar, but that's another bug...  :-)

[Bob Lord]

Simon: are you still seeing this problem with the latest builds?

Comment 14

[Bob Lord]

My previous test (which worked) was on Win2K.  I just confirmed that this works
on my home WinME machine as well.  No hang and no crash.

Worksforme with the 6/25 branch builds on WinNT, Win98, Linux and Mac.

Note that simply going to the sourceforge site, and having it work, is not 
sufficient to test this bug. On the day that I saw this bug, akamai were having 
network issues, so some of the iamges on the page were failing to load, and this 
was causing the browser to hang.

So to really test this, you need to set up an https site with pages that have 
images (maybe http, maybe https) that fail to load (or reside on a very slow 
server), and check that this does not hang the browser.

I constructed a page with images loading from other web servers:
https://beaver.netscape.com/moztesting/82799.html
and same with http.
I don't see any hanging there. If there is a bug here, it require such a
peculiar set of circumstances that it can't be considered a blocker.
target -> 2.1

Marking worksforme. I'm not seeing any hanging with secure sites.
