Status: VERIFIED WORKSFORME

(SeaMonkey :: Location Bar, defect)

Description

[Timothy]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021212
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021212

My browser freezes when I let it browse to  //  .
It will not respond to any interaction like mouse clicks or keyboard shortcuts,
but still keeps itself visible in a way that the program is "working", and not
crashing. In the meanwhile it starts eating memory and CPU usage until the whole
system crashes, but that only happens after about 1 minute if the browser isn’t
shut down with task manager.

Reproducible: Always

Steps to Reproduce:
1. Type  //  as location url
2. Hit enter

Actual Results:  
The browser froze, and didnt respond to any input.
In the meanwhile it started to eat all the internall memory and CPU usage,
Causing a full OS crash

Expected Results:  
Change the  //  url into  http:///

looks releated to bug 134793.

mozilla must not convert to http:// but it should not hang.

-> darin (or possible URL Bar ?)

reopening because this bug should be a) in networking until darin decides this
should go to URL bar and b) this bug conatins more information

Two points:

1- My personal preference is that duplicates should go to the first reporter. It
is sort of a way for giving them "credit", because that bug remains open.
However, sometimes bugs do not get enough analysis, or someone comes along with
a better description and the community find the later duplicate more useful. So
be it.

2- The litmus test for "URL bar" vs. "Necko" bugs is this:

Put the questionable input into a html document as an HREF. Click on it. If it
works fine in a link, Necko is not at fault.

So in this case, if you look at the URL field of the previous bug, and click on
the link (viewsource says " <a href="//">", you find that Necko returns an error.

So this should go to URL bar. (Lets not reverse the duplicate again, things are
fine the way they are now.)

BTW, "//" messes up Phoenix 0.4, Win 98 as well...

On the Mac OSX 10.2 Mozilla 1.3a 20021129
// in the URL bar is automatically changed to file:/// and a file list is
displayed.  The system does not hang.

I have also experienced the // hang on Win98 with Mozilla 1.2.1 and 1.3

In my case (Mozilla 1.3b Gecko/20030218, Linux i686) "//" changes to "file:///".
But "://" completely freezes X.
Different troubles?

This seems to be resolved in nightlies.  I now get the message "The URL is not
valid and cannot be loaded" message instead of a hang.

Currently tries to take me to http:///

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7b) Gecko/20040229
Firefox/0.8.0+ (djeter)

Results in 

The address (URL) is not a valid format and cannot be read. A typical address
will start with "http://", followed by an address, (e.g. www.netscape.com),
followed by a path to the content (or just "/"). A common cause for the problem
is using backslashes(\) instead of forward slashes (/).
