Extremely long URLs don't display properly

[Adam McMaster]

Binary package hint: firefox

See attached screenshot. In this case the URL is almost 55KB of text.

screenshot of problem on linux

I swear I'm not crazy. Could be linux-only :)

[Peter-vanderwoude (peter-vanderwoude)]

1. have you tried in -safe-mode to rule out any extension ?
2. did you try the official build ?

[Vladimir Vukicevic (vvuk)]

This also happens for tooltips for long bookmarks (e.g. javascript scriptlets).

No extensions installed, I'm running the official DP Alpha 1 build.

Can someone attempt to verify this on linux? It could just be a Gtk gfx problem.

The overlap problem is not just from pasting a long URL. It can also result from a long URL derived from an HTTP GET operation. The instructions in bug 338510 explain how I was able to cause overlapped text consistently.

This is very similar in effect to the bug I'm seeing on Mac: bug 348202, which only became apparent since fixing the vanishing-long-line problem (bug 237085). It appears that if you have a long line of text with no breaks or whitespaces, at a certain length vs text size the end of the text begins to be drawn over the start, and vice versa. The text is also still drawn in its original position, so it's not like it's being wrapped around... it's just a copy of it that appears where it shouldn't. The more you increase the window text size, the more of the long line is covered by the duplicate text.

Another long word sample in page content.

I can confirm this happening in the address bar, in input fields and in page content. I'm using mozilla-firefox-1.5.0.6 on Gentoo Linux.

I have replicated this as well using a poorly written cgi script for a web-based email system.

The cause was clicking a hyperlink containing a very large URL (>4k, and possibly >8k - my cut/paste buffer in xfce is only 4k). This happened because the code embedded the entire body of an email message in the URL itself.

Apart from garbling the address bar, on a Dell Lattitude D620 (using an nVidia card with the proprietary nVidia drivers), mousing over the address bar seems to "reliably" cause X to crash.

I should add I'm using 1.99+2.0rc3+dfsg-0ubuntu1 on edgy.

Is this still an issue with Firefox 2?

[Adam McMaster (adammc)]

Yes. This still happens with the latest Firefox (in Feisty).

Hello Adam,

Can you give us an example of a URL you are experiencing problems with, what actually happens and what you expect to happen instead, this will greatly aid us in solving the problem.

Thanks, Alex.

[Adam McMaster (adammc)]

The specific example is a form from cPanel which modifies an apache configuration file. For some reason it uses method="get" instead of post. I've attached a copy of the page, click Save Configuration to see what happens.

[Alex Latchford (alex.latchford)]

Aha ok, I get what you are seeing now, I presumed that you had masked the Address Bar in the previous screenshot, not that that was the bug :)

Okay, I am going to send this bug upstream and see what they feel the problem is.

Thanks again, Alex.

[Alex Latchford (alex.latchford)]

Woops linked in the wrong one. This should be the one we are looking for.

Thanks, Alex.

Not that it matters, but afaik, GET urls must not be longer than 4096 according to HTTP standard ... so your webapp is properly messed up it it uses GET for submitting text forms.

Anyway, no question, the rendering problem is a bug.
